Class Ψ

• Unsafe
• Mental Hazard
• High Entity Count

Description

Structure Overview

Level 667 consists of an unknown amount of gigantic PMMA (Polymethyl Methacrylate) hollow spheres¹ and their contents, as well as the heavy water sea with an extremely high content of deuterium and tritium. The level features a 24-hour day and night cycle with an equal duration of day and night. The climate is pleasant, but thunderstorms and heavy water rain frequently occur.

The PMMA spheres contain a remarkably wide range of contents, including but not limited to, microcities, non-Tokamak² nuclear fusion power plants, abnormally large amusement parks, and wastes. The contents of each sphere are categorised in accordance with their general common characteristics as the styles and specific impacts of each sphere are not entirely consistent. See below for more details.

The heavy water sea is the only supply of raw materials for the aforementioned non-Tokamak nuclear fusion power plants since, as its name suggests, it includes a significant volume of heavy water that cannot be consumed and contains deuterium and tritium atoms. There are no other significant structures in the heavy water sea that are large enough to be seen with the naked eye from a distance except for the PMMA spheres. Other floating buildings, including little rafts, sailboats, and miniature cruise shipwrecks, are visible at times, though. The evaporation of heavy water sea is minimal, but it is sufficient to combine with freshwater to create rainfall. The sea is the only source of the level's radiation hazards, but due to the level’s abnormal nature, the radiation hazards have been reduced to a level that can only result in nausea, headache, and other symptoms during first-time entry. As yet, there have been no reports of wanderers dying of these diseases.

Mental Hazard

Level 667 contains a fully covered mental hazard. This mental hazard undergoes periodic changes, and the following actions can be taken to promote its development:

• Drinking any amount of heavy water in the level.
• Being injured by a special entity in the level.
• Hearing a noise at a particular frequency (the noise frequency varies according to the location).
• Seizing others' M.T.S.G. devices.
• Killing a certain amount of fore-keepers.
• Inhaling heavy water vapor long-termly or contacting the any surface with heavy water.
• Long-term exposure to a special PMMA dome³.

The stage promotion effect of the mental hazard is typically not enhancive, but it rather directly turns the performance of the affected to those with a comparable effect, including but not limited to:

• α: Regarding other entities and wanderers in the level as hostile targets and having a non-fatal predatory inclination.
• β: Showing an unusual desire for the water in the heavy water sea. The purpose of this desire is to simply fill the stomach.
• γ: Robbing the M.T.S.G. of others and destroying their existing blueprints.
• τ: Destroying the normal vegetation accompanying the PMMA spheres' contents⁴.
• θ: Having a strong desire to approach an unknown coordinate. Dozens of wanderers carrying lethal weapons with unknown purposes are currently reported missing.

Matter Transmission & Synthesis Gun (M.T.S.G.)

In Level 667, the M.T.S.G. is a special processing tool that will be unusable in other levels. Although the M.T.S.G. looks like a white, streamlined "welding gun," it has far more uses. It has a side ionic fluid thruster and an embedded LCD in the rear. The M.T.S.G. can process materials (such as crushing, melting, splicing, etc.) on a solid surface according to a blueprint to manufacture different items in addition to general welding and melting operations. It should be noted that the M.T.S.G. can carry out relevant operations regardless of the various physical characteristics of the materials or the phenomena in the Backrooms. Self-controlled processing does not require manual operations, but the M.T.S.G. relies on the ionic fluid thruster to change its pattern. Since its interior precise structure is readily broken during disassembly, all current attempts to reproduce the M.T.S.G. have failed. Although having a precise structure, the M.T.S.G. performs relatively solid and reliable under normal conditions.

When wanderers no-clip into the level, the M.T.S.G. will appear inside a circle of about 3 yards from their current location. The M.T.S.G. can be replaced by taking other wanderers' M.T.S.G., however doing so will alter the stage of the aforementioned mental hazard. The M.T.S.G. is the main and most valuable survival tool in the level, and whether to pick it up depends on the wanderer's situation. For information on using the M.T.S.G., please read the following documents. The technical grades mentioned below are classified according to the M.T.S.G.'s unique identification system. Similarly, material consumption is also defined according to the original text.

The only way to charge the M.T.S.G. is to find specific buildings with charging interfaces. The use of ultracapacitors allows the empty battery to be fully charged in around 8 hours. The fully charged battery can maintain a hover state for a maximum of 20 hours. The non-Tokamak nuclear fusion power plants in the level are the source of all currently known energy resources.

Spatial Anomalies

The environmental stability in Level 667 change at all times, and these changes usually have disastrous effects. Spatial anomalies known from the summary report are as below:

Falling Curves
The "sky" in the level abruptly collapses in the form of concave triangles and convex triangles in non-Euclidean geometry. Perfectly straight-cut fragments of buildings will roll down from the edges of convex triangles and injure wanderers and PMMA spheres. The PMMA spheres are vulnerable to attacks from ultraviolent falling objects.

Sphere Drifting
Rarely, PMMA spheres floating in heavy water will drift due to strong underwater disturbance, which will easily result in the disconnection of PMMA corridors connecting the spheres or the collision of two or more PMMA spheres, directly leading to the full disintegration of the dome. After that, the heavy water may flood into originally enclosed spheres, contaminating sources of drinking water and preventing normal vegetation from surviving. Long-term investigation has confirmed that this anomaly is related to the overuse of non-Tokamak nuclear fusion power plants.

Transmission Corridor Blast
When the aforementioned occurrences take place close to the PMMA spheres that contain nuclear fusion power plants, the wireless substations connected to them may be damaged, causing transmission corridors to form arcs and allowing the current to flow outside of areas with danger signs, posing a high-voltage electric shock threat to wanderers.

Entities

Processes-29

• Process-29 is a unique entity in Level 667 as a result of the spatial instability. When there are falling curves, some of the fragments that come from convex triangles will be imposed with an unknown angular momentum, begin rotating quickly, and continuously destroy the objects until they are totally worn. Process-29 is classified as an entity for its preference to destroy organic life and its target appearing to have a distinct direction after rotating at a high speed. We discovered the report files of this entity, named "Process-29", while investigating the Unknown Coordinate.

Fore-keepers
Fore-keeper is a unique, highly intelligent mechanical organism in the level. Its advanced motor nerve center appears to be very viscous suspensions of brain tissue as compared to complete robots, meaning that powerful shocks won't impair its thinking or actions. Yet as soon as the suspension leaks, all of its essential actions will be completely paralyzed. According to anatomical studies, the tissue cells of the suspension in the cranial cavity of fore-keepers communicate through plasmodesmata, which discharge at various frequencies to enable the communication. The body of the fore-keeper appears to be a dark-green robot, and its body is very solid except for its cranial cavity and connecting parts. The general work of the fore-keeper is to take care of plants in PMMA spheres; if a sphere is slightly damaged, the fore-keeper can restore it by itself. When a significant damage is discovered, a group of fore-keepers can also assemble timely and use specialized machinery to restore the dome. The tools and weapons carried by fore-keepers include PMMA hot-melt guns, gardening tool kits, and stun air rifles. Fore-keepers are friendly to wanderers and are hostile to Sharkopards. They cannot attack Processes-29, however, when attacked by humans, they will use a non-lethal stun air rifle to strike back. Sometimes they will seek the help of wanderers when they need to start the underlying components of specialized machinery. The reward for this help is generally a special blueprint that is difficult to find in other parts of the level.

Sharkopards
Sharkopards are the only organic and highly intelligent animals in the level that is inferior to humans. They reside on barriers formed by fragments in the heavy water sea and in submarine bases. The upper part of their body appears to be the front end of the shark, and their legs, which have the appearance of shark leather, is legs of a leopard. Sharkopard can't use the M.T.S.G. but can acquire weapons with a technology level slightly lower than the M.T.S.G. products from submarine bases. They have a potent short-range explosive force, are amphibious, and hostile to wanderers and fore-keepers. Sharkopards have a strong predatory propensity and are open to allowing wanderers suffering from long-term stage τ and β mental hazards to join their predatory groups. They have even been known to attack nuclear fusion power plants⁵, occasionally causing heavy water to pour into PMMA spheres, polluting the source of drinking water. With the aid of their special lasso, Sharkopards can also bind Processes-29, making them a lethal weapon for destroying the dome, but it also gives us a new way to avoid falling curves. Sharkopard strongholds have been observed frequently recently; we need to pay closer attention to them and continue reporting on their trends.

Plasmaniacs
Plasmaniacs, whose bodies exist in a highly unstable plasma state and whose movement speed varies from one another⁶, will appear next to leaky substations. Despite not having a physical body, they project a fuzzy human shape made of current that is capable of paralyzing all nearby electronic devices. The physical hazards of Plasmaniacs have various effects because of various relative positions between wanderers and them, with them as the center: wanderers within the radius of 12 meters will experience a strong tingling sensation; within the radius of 7 meters, wanderers completely lose their sense of touch but can still use weapons; within the radius of 4 meters, wanderers will directly faint; within the radius of 2 meters, wanderers will be instantly vaporized and turn into new and weaker instances of Plasmaniac. S1 (Scale 1), S2, S3, etc. are used as the names for these new instances, up to S6. A native Plasmaniac won't exist for more than two hours, but Plasmaniacs invading in densely populated areas still pose a serious threat to the locals. Without effective counterattack strategies, the entire community - including wanderers and fore-keepers - will be devastated.

Steel Bustards
Steel Bustards are the most enigmatic mechanical beings of unknown origin in this level. They resemble birds in appearance and can carry resources. Resources carried by Steel Bustards are various materials from fragments on the heavy water sea, as shown by the use of specific isotopes other than deuterium and tritium to trace them. The process of gathering resources at the heavy water sea typically takes 48 hours, and each Steel Bustard has its own operation route. After gathering resources, they will go back to their own route and stay for two hours at the berth of each PMMA sphere. At this point, wanderers are free to take the supplies brought by the Steel Bustard or to place their own supplies.

Bases, Outposts and Communities

One of the entrances to the M.E.O.D. Base Network "Fore-guard".

M.E.O.D. Moderate Base Network "Fore-guard"

A base network under the control of the M.E.O.D. that is used to receive wanderers that entered this level and produce weaponry to be exported to other levels. Now, the network occupies 24 PMMA spheres and 27 heavy water sea structures. Although there are more than 6,000 people living here, the population is distributed very unevenly. The largest city, City-β, accommodates more than 1,000 residents.

M.E.O.D. Base "Squadron Shark-hunter"

Another large-scale M.E.O.D. base, established to resist large-scale Sharkopard attacks. At present, the base occupies 12 PMMA spheres and 49 heavy water sea structures.

The F.O.J. Outpost

In this level, the Followers of Jerry actively spread their beliefs and use Steel Bustards to distribute leaflets about Jerry. Under the influence of Jerry, the mental hazards to those followers have been reduced a lot. Their passionate missionary activities even prevented the M.E.O.D.'s "Parachute Project" to rescue wanderers from being put into operation. After a small-scale conflict with the M.E.O.D., the F.O.J. agreed to do missionary work by painting the Steel Bustards that land on the ground blue and putting the slogans on them. At the same time, the M.E.O.D. will place life rafts on such blue Steel Bustards to rescue wanderers in danger. It is suggested that wanderers do not believe the slogans on blue Steel Bustards.

P.R.I. (Pallas Research Institute) Scientific Outpost PLS-SO-FC

The majority of the level's laboratories are occupied by this outpost, which conducts entity research and tries to interact with Sharkopards in order to come up with workable solutions for innocuitizing them. Currently, the "Blueprint Project", which strives to develop more complex blueprints and quickly produce more advanced equipment, is receiving the majority of the outpost's scientific research resources.

Other bases and outposts' personnel are classified as residents.

Entrances And Exits

Entrances

• Finding a leaflet on "Forecity B-29" with a "Corporate" logo in a wreck in Level 711 and no-clipping into it will lead to this level.

Attack & Defense

Harpoon Sharkopards

Sharkopards with a low level of ability that can act rapidly with their harpoons and can also attack with their mouths. A single Harpoon Sharkopard can be directly repulsed using firesalt. When encountering a group of Harpoon Sharkopards, they should flee without being discovered; if you are discovered, please run and hide behind any nearby obstacles.

Shotgun Sharkopards

Shotgun Sharkopards have poor dexterity. The shotgun of this kind of Sharkopard comes from submarine bases, and despite having a limited range, the accuracy of the Shotgun Sharkopards is rather high. The shotgun uses round lead bullets or ordinary steel bullets. Shotgun Sharkopards are not good at close combat and have weak static eyesight. When a Shotgun Sharkopard is alone, wanderers can try to approach it and knock it down to obtain the shotgun - long-range weapons are particularly valuable in this level. When killing a Shotgun Sharkopard, be careful to look around to see if there are any other Shotgun Sharkopards hiding nearby and avoid stepping into their area of concentrated fire.

Bombing Sharkopards

Bombing Sharkopards who use self-made simple bomb-throwers to attack are usually more muscular Sharkopards. The old bombs they use is obtained from submarine bases with reformed detonators. Bombing Sharkopards are few in quantity, but they generally only show up in medium and large-scale attacks. If you observe a single Bombing Sharkopard, please shoot it down in time, and we will give you corresponding rewards. Your contribution will help us build a safer community in this level.

Lead Sharkopards

In comparison to other Sharkopards, Lead Sharkopards are easy to identify because they are armed with a shotgun and a Samurai sword and have a bulletproof board covering their front. Often, the only way to kill a Lead Sharkopard is to shoot them in the head. Lead Sharkopards are just Shotgun Sharkopards with better defense, but their leadership skills make them fearsome opponents. They can appear in a variety of small and medium-scale attacks, and they usually bring 2 to 4 attendants. As there is no way to estimate how many Sharkopards are still being ambushed nearby and underwater, wanderers should not directly conflict with Lead Sharkopards' team.

Plasmaniacs

If the first place you show up in the level is next to a substation, do not enter the substation unprotected in order to look for supplies. Please immediately evacuate to a location 500 meters away from the substation if you experience intense shaking or see curves falling from the sky, and pay close attention to the transmission corridors in mid-air. The corridor has been overloaded and there is a risk of electrical leakage when the outer collars of the corridor turn red. At this time, it is necessary to seek an indoor shelter in time and earth all possible entrances to the shelter with wires. This method can eliminate Plasmaniacs. When encountering a Plasmaniac while exploring in partnership, you should keep a distance from your partners to prevent them from attacking you after turning into a non-native Plasmaniac. Throwing firesalt at them will block their attacks because it will temporarily scatter their non-physical bodies.

Runaway Steel Bustards

The normal behavior of Steel Bustards is neutral or friendly, but some Steel Bustards may experience component rustiness and switch on their self-defense mode after being submerged in heavy water. experience component rustiness and be activated in their self-defense mode. Their wings become extremely sharp, their airspeed is substantially boosted, and they are in a no-load state in this mode. They launch indiscriminate attacks with their swift wings against wanderers and other entities. When you come across them, don't panic; instead, look for enclosed spaces nearby and, if possible, shoot them down. If you are in city-α, you can seek shelter in the small VTOL airport.

M.T.S.G.

The usage of the M.T.S.G. falls into two cases: self-controlled processing and manual processing.

Self-controlled Processing:

The M.T.S.G. processes an adequate amount of materials in accordance with the blueprint that has been input into it, producing the final product specified in the blueprint. The final product by self-controlled processing has high quality and strong durability. The blueprint must be converted to digital form before being output to the M.T.S.G. through a storage device. When using the M.T.S.G., be aware of its state of charge and the anticipated power usage of the product; at least 10% of the power should be reserved for emergencies.

Wanderers should collect the following basic materials before using the M.T.S.G., including but not limited to:

• High-quality Steel
• Lead Ingots
• Glass Shards
• Planks
• Baobab Fruits

These materials can be used to make simple self-defense weapons with the simplest blueprint.

After that, within the PMMA spheres, wanderers should search for a charging interface for the M.T.S.G., which can show up in a variety of small, enclosed spaces like bedrooms and utility rooms.

Preparations before using self-controlled processing:

• Check SOC and switch to self-controlled processing mode.
• On a relatively flat, dark desktop, mark the scanning area with the marker pen attached to the M.T.S.G. A rectangular area is recommended.
• Select a blueprint.
• Place enough materials.
• Start the M.T.S.G.

Manual Processing:

Manual processing is typically used to process non-blueprint components or to modify surrounding objects in an emergency to use them as a shelter. According to feedback from residents in the level, they generally use the manual processing to make shelters out of some discarded steel plates, to make double glazing for sound insulation, or to make insulation shields out of thick layers of PMMA.

There have been only 4 reports of special use of M.T.S.G., all of which occurred when wanderers encountered injured fore-keepers. When they confirm that the wanderers show no hostility, it is said that the injured fore-keepers will approach them and request help from the M.T.S.G. According to reports, their M.T.S.G. can fix their limb damage and even fill in holes in their cranial cavities. Wanderers will receive a small communication module in return, which can be used to contact them or even the specialized machinery they use to summon reinforcements in an emergency.

Refuge

Falling Curves:

Do not panic when there are falling curves. People working inside the domes should immediately move to the underground area, while those outside the domes should flee to areas with more barriers. A typical size Process-29 can pierce 6 to 8 reinforced concrete walls that are around 5 meters thick, for example. It is best to leave space of two barrier distances at least to prevent attacks from Processes-29.

Sphere Drifting:

The best way to prevent damage from sphere drifting is to prepare life rafts in advance, load them with essential supplies, exit the PMMA sphere and board a life raft two hours before the anticipated collision of the two PMMA spheres, and row the raft to a location 1200 meters away from the sphere within two hours. If you don't have a life raft, you should choose a shallow underground area near the PMMA sphere's center to take refuge. In order for wanderers to quickly clear the escape passage from the debris in an emergency, it is advised that they carry explosives and blasting equipment when escaping.

Transmission Corridor Blast:

As a secondary disaster of the two aforementioned disasters, transmission corridor blast will release a large number of Plasmaniacs, and their presence will result in unimaginable casualties in densely populated areas. When your group encounters a complete leakage in transmission corridors, escape to the inside of a nearby structure, and use pyroil to set the ground in front of you on fire to prevent Plasmaniacs from approaching. Then, use the M.T.S.G. to create an insulation plank to keep Plasmaniacs out. Make sure that all of the Plasmaniacs outside have completely vanished before leaving the structure.

Heavy Water Rain:

The weather outside the domes, where all of the precipitation is almond water or pure water, is very different from the one inside the PMMA spheres. However, the heavy water rain outside the domes presents a serious threat to wanderers. Those who are exposed to the heavy water rain will start to experience mental hazards, and excessive soaking in heavy water rain can cause irreversible physical damage. When encountering heavy water rain outside the dome or on the heavy water sea, use your M.T.S.G. to quickly create a steel plate with a thickness of about 1 centimeter and a length of 50 centimeters into a foil according to the blueprint, then use it to cover your body to avoid contact with heavy water rain as much as possible.

Sharkopard Pillaging:

A relatively rare disaster brought on by Sharkopards, but just as dangerous as the aforementioned spatial anomalies or natural disasters. Sharkopards frequently organize predatory operations inside the PMMA spheres, but they cannot survive within the PMMA spheres for a long time, so they quickly retreat to their barriers and submarine bases after the operation. Wanderers should stay calm, adhere to the M.E.O.D.'s instructions, be compliant to agreements, and work together to resist invasions when Sharkopards conduct predatory operations.

Locked Information 1 - Overview of PMMA Sphere Structures:

This is a thorough introduction based on the various properties of each PMMA sphere's contents, to help you quickly adapt to various situations and make correct decisions in the level. In fact, the so-called "city" is much smaller than a real city; the average radius of the PMMA spheres is only about 300 meters.

Structures

Domes

As mentioned earlier, the semispherical domes are made of seamless PMMA doped with titanium dioxide microcrystals. The maintenance of the dome is essential because it serves as the main safety net for the creatures inside. After various disasters or attacks, the dome needs to be repaired as soon as possible, and when wanderers are unable to repair certain sections themselves, they should contact fore-keepers to use specialized machinery for repair. There are a small number of steel skylights above the dome for Steel Bustards to berth.

Roads

Roads in the PMMA spheres have little use because there is little transportation in the level, but they are suitable for arranging defense when trying to stall invasions. triple-layer paving technology is employed for the road. Periwinkle sand makes up the bottom layer, followed by a wood coating made of Brazilian mahoganies and sycamores in the middle, and delustered PMMA plates on top that allow wanderers to vaguely see the strange patterns reflected by the coating below.

Habitation Units

The habitation unit is a collection of large buildings with living facilities in the level. The habitation unit has a uniform appearance, with a futuristic, streamlined architectural outline. It employs minimal indoor and outdoor design and is fitted with high-quality glass with seamless connections.

A single suite of habitation units has a kitchen, bedroom, and bathroom. It also shares a living room, storeroom, and a small interior garden with other suites. This arrangement creates a smaller community around the interior garden, which strengthens the sense of community among the wanderers residing in the unit.

There are M.T.S.G. charging interfaces in the kitchen and bedroom that guarantees the long-term use of the M.T.S.G. The interior garden has a delivery point nearby that appears to be ductwork and is where supplies are periodically dropped. The duct's measured depth is 15.12 meters. Although the origin of these supplies is unknown, it can be determined that the ductwork is separate and has a dead end.

When the PMMA sphere is not seriously damaged, and the transmission corridors continue to work normally, the habitation unit have a sustainable supply of water and power, both of which come from non-Tokamak nuclear fusion power plants. However, the corresponding relationship between habitation units and power plants is unknown.

In the habitation unit, there is an empty underground area that is connected to the other underground facilities.

Overall, the living space of the habitation unit is adequate, but due to its relatively hollow interior, it is not a suitable place to defend against attacks from Sharkopards. When pillaging occurs, wanderers should retreat to the underground area in time. As per the instruction of the M.E.O.D.'s defense standards, the underground space has been stored with enough supplies for 200 people to survive for 2 months and employed with modified M.T.S.G. charging interfaces, so all defenses should be deployed in the underground area.

The Mall

The mall is actually a large shopping and entertainment complex, but the majority of its entertainment installations have vanished, leaving only a few smaller, single-person entertainment facilities like individual KTV rooms, massage chairs, VR exercise equipment, etc. The mall's shopping area is relatively well-reserved, with a few useful instrument supplies on the shelves.

The M.T.S.G. charging interfaces are easiest to find in the mall, with a charging rate that is 130% faster than the civilian charging interface in the habitation unit. Additionally, the mall's hidden corners contain many advanced blueprints.

The architectural design of the mall is extremely complex, with passages relying on elevators. There are fewer entrances and exits on higher floors, making it easier to defend against attacks and more challenging to attack. Therefore, during the period of defending pillaging, the mall is frequently used as the living center.

City-α

City-α appears to be a massive, liminal streamlined architectural complex.

The Estimated Survival Difficulty of City-α

Livability——3

Supplies Adequacy——4

Population Density——4

Dome Theseus

Dome Theseus uses a different type of PMMA than the other PMMA spheres. The special material causes the light transmitted into it to appear unnoticeable light yellow, creating a bizarre dusk scene inside the dome. However, this enchanting light can promote the stage of mental hazards, so long-term staying in City-α outdoors is not recommended.

Dome Theseus.

The Quadruplet Tower

The Quadruplet Tower, located in the heart of City-α, has limited living supplies, but it has a large number of available information terminals and M.T.S.G. charging interfaces, as well as a rooftop parking area.

The Quadruplet Tower’s exterior appears to be a square structure consisting of four cone-shaped spires connected by corridors on the upper part. There is a pool in the center that can continuously pump out Almond Water, which can be used as a long-term source of drinking water. Most intermediate floors have a typical Corporate office building appearance, with unusable office equipment. However, some snacks such as chocolate bars, nut candies, freeze-dried fruits, etc., can be occasionally found in the drawers. Luckily enough, even some blueprints can be found.

The base of the Quadruplet Tower has a security site with heavy anti-theft doors. The site stores stun air rifles with the same model as the ones carried by fore-keepers, as well as some ordinary gunpowder stored in powder-horns. Basic riot gear such as steel forks, riot shields, teargas, and powerful flashlights can also be found. Interestingly, the names of the security guards in these security sites are all Process-81.

The Small VTOL Airport

The Small VTOL Airport is a type of heliport with a radius of about 20 meters. There is a 32% chance of finding a two-seat helicopter without engines here, and below the helicopter is a unique light strip flashing blue lights. The ground near the heliport is equipped with a small terminal building and a narrow power distribution room.

By collecting data from the terminal building and power distribution room, we discovered that two types of aircraft should be parked here, but currently only the helicopter without engines can be found. The other type of aircraft is a quad-rotor UAV. The blue light strip on the ground marks out the wireless charging coil of the transmission corridors, which can directly charge the M.T.S.G.

Another characteristic of the VTOL Airport is its ability to drive away Runaway Steel Bustards, which will retreat to an area 40 meters away from the airport.

City-β

The overall appearance of City-β is nothing different from City-α, but there are more plants in the habitation units, most of which are edible. Besides, the underground area of City-β has been heavily reduced, with only its unique underground structures remaining. Overall, it can be classified as a research-centered city, with the most corridor joints.

The Estimated Survival Difficulty of City-β

Livability——5

Supplies Adequacy——5

Population Density——4

The Pit Hotel

The Pit Hotel is usually located by the second ring road of the city center. The main rooms of the hotel are built on the inwall of the area 40 meters underground, and the other components of the inwall are steel caissons discovered through drilling, which are used to maintain the balance and stable floating of the PMMA sphere on the heavy water sea.

There is a group of fountains that periodically spout Almond Water in the center of the Pit Hotel. The living conditions in the Pit Hotel are better than those in the habitation units, so it is also used to accommodate common residents other than the M.E.O.D. combatants. Due to its unique terrain, it is rather easy to protect the Pit Hotel.

Supplies and resources are adequate in the Pit Hotel, making it the top choice for most wanderers to settle down.

The dome in City-β

The Corporate Co. Industrial Laboratories

The Corporate Co. Laboratories are located in the northwest of City-β, appearing to be steel spherical buildings built in imitation of the appearance of PMMA spheres. Most of the facilities inside the lab are no longer functional, and even those that still work are easily damaged, making it difficult to operate at full power.

Although it no longer has its former functions, basic quantitative substance analysis research and some simple experiments can still be conducted in the lab. Therefore, several scientific research groups have been deployed in the labs to conduct in-depth research on the recording of the exploration of the level. Currently, the M.E.O.D. has taken control of 14 Corporate Co. Industrial Labs.

The exact ownership of the labs is unclear, but it can be learned from some incomprehensible and indecryptable laboratory reports that the laboratory belongs to a large commercial corporation named Corporate, whose logo appears in most industrial areas in the level. The current CEO of the corporation is named Process-42.

The Spiral Base Station

The Spiral Base Station is the signal source of all Wi-Fi in the level, and the signal strength around the station decreases according to the following formula as the distance increases:

\begin{align} \it{S}=\it{S}_{0}*e^{-1.2θd} \end{align}

Note: S is measured in signal strength bars, and S₀ is the default value of full strength (5 bars); d is the distance measured in kilometers; θ is the correction factor, which is set at 1.2 as an expected value.

It can be inferred from the formula that Wi-Fi in the level is not fully covered, and the limited number of Spiral Base Stations in the level also leads to blind sides in some areas. However, this can be solved by installing specific repeaters in the level, which are necessary in important bases and offices.

The Spiral Base Station is an optical cable clustering signal tower with a special glass core and a steel plate cover. The space inside the tower is extremely narrow, but there is usually a chance of finding repeaters, safety helmets, and empty toolboxes in the maintenance room near the top of the tower, but no food supplies have been found.

City-γ

City-γ is relatively small compared to the first two cities, with a determined radius of only about 240 meters. Such small area has led to reduction of typical buildings inside the city, but has increased the number of other unique structures in the city, making its structure more complex from both the planar and steric perspectives. All habitation units in the level are located on the outer circle, reaching straight up to the dome, forming a cylindrical internal space with them as the curtain wall. Generally, the central area of the curtain wall is more habitable, but due to the lack of survival resources, only few wanderers choose to live here. Most residents of the habitation units are garrisons dispatched by various groups to scavenge materials.

The odd-numbered floors of the habitation units that make up the curtain wall transform into malls every other half day. However, the supplies that appear in these malls are extremely different from those that appear in typical malls.

The center zone of CIty-γ.

Gun stores

A large structure protruding from the curtain wall that appears during the transformation of the odd-numbered floors of the habitation units.

After several explorations, it has been found that the shelves of this structure store firesalt, conventional gunpowder, and steel bullets of various radius, as well as lead bullets with a large range of time spans. Rarer items are long-range firearms, with the highest record of discovering 5 at once. These firearms include but are not limited to: breech-loading carbines, automatic loading rifles, and the rarest marksman rifles. All firearms except marksman rifles can use traditional gunpowder and firesalt, but may require a ramrod when firing.

The logo of Corporate Co. can be found in the gun stores.

Lighthouses

An abrupt structure in CIty-γ.

The Lighthouse is a structure similar to the Spiral Base Station in City-β, with the difference being that it is used for lighting at night. Its light transmits in a wide-range way, making streetlights in City-β unnecessary.

There is a small operation room inside the lighthouse, which is totally empty, without even any report of discovering blueprints. However, the operation room can be used to focus scattered light at a point, making the minimum radius of the lightspot to be 2 centimeters, making the light intensity extremely high. It can even melt the surface of fragile metals and be used as a searchlight to target enemies in night battles.

Waste Treatment Facilities

Waste treatment facilities are specifically used to collect and process various types of domestic waste from habitation units in the level. Currently, only the slots of these waste treatment facilities can be found on the curtain wall. It was discovered that the end of the discharge pipes is a dead end when conducting further investigating, and the furthest visible section of the pipes is a cube block with a side length of 72 centimeters covered with white film.

The devices inside the waste treatment facilities can be started and stopped by using the corresponding touch screen in the central control room, where blueprints can be found. However, the more valuable items in the facilities are film blowers, hydraulic presses, and hammer mills.

The Crystal Spiral

There is only one Crystal Spiral in CIty-γ, located within 12 meters of the central point.

The Crystal Spiral features a steel frame, and uses PMMA as the surface of its steps, which can reach the top of the dome. Occasionally, minimal supplies and some inexplicable notes will appear on the steps of the Crystal Spiral. The following are extracts of the identifiable contents of the notes:

Coordinate (392,0██), heavy gunfire- Backup

Northeast, city-α, sea fragments, hurry up! We are running out of t-

Down here. These demons want people with guns, like us. I can't go back.

Amusement facilities, waste spheres, metal… metal, I, I don't remember-

Currently, the M.E.O.D. is collaborating with other groups to conduct joint operations, hoping to find the location mentioned in these notes.

Treehouses

Another abrupt structure in CIty-γ.

Treehouses are built on baobab trees and maple trees that grow on both sides of the curtain wall. The overall layout of the treehouses follows that of a single bedroom. The decoration style inside the treehouses is simple, containing only an external M.T.S.G. charging interface, a vine bed, two nightstands, two bamboo blinds, a set of desk and chairs, and a vine ladder. A blueprint will appear on the desk.

There are no other supplies in the treehouse, but its soothing environment is beloved by wanderers in City-γ. Now, it is generally used as a leisure club or a small conference room.

City-δ

City-δ is the last city that exists within the PMMA sphere. This city is the second most habitable city after City-β, but has a lower population density due to the extreme mismatch of resources and living facilities. After all, no one likes to live in extremely poor environments with their hard-earned resources. The area of City-δ is not much larger than that of City-γ, with few malls and habitation units, and fairly unitary buildings. Overall, it appears to be a temporarily constructed new city with inadequate facilities.

Livability——3

Bungalows

Bungalows are the single-story buildings made by jointing containers in City-δ, forming a vast building complex.

The basic unit of bungalows - a container - is 7.2 meters long, 2.8 meters high, and 2.2 meters wide, white both inside and outside. The most common layout in a bungalow is a cramped bedroom that contains a central air conditioning, which constantly sets a temperature according to the best body feeling temperature. Therefore, we recommend that the wanderers who have settled in bungalows hang out periodically to avoid the decline of body functions caused by long-term automatic temperature regulation.

The kitchen and dining room in the bungalow are composed of two containers combined together. The white inwall between them is replaced by an PMMA curtain wall. The kitchen contains a four-door refrigerator and a freezer specifically used to ice drinks. Almond Water may appear in the refrigerator, and 2 to 3 bags of Candy may appear in rare circumstances. There have been only two reports of finding Royal Rations.

The living room and storage room are composed of three containers combined side by side. The side containers are equipped with large chests that can be used for storage, and when the lid is closed, they can be used as seats surrounding a rectangular long table.

The power source of the air conditioning is the non-Tokamak nuclear fusion power plants, and the outdoor unit of the air conditioning is a prototype turbine, located above the container used as the kitchen.

The long-term living experience in the bungalows is extremely awful, not only because of the small area of these containers, but also because the dazzling white ceilings can induce photosensitive epilepsy, and make wanderers ignore other objects in the container, causing a strong sense of loss and desperation, leading to the reduce of living and work efficiency. Currently, the living pattern we recommend is to spare some of the bedrooms and share your rooms with another two wanderers to eliminate this sense. Works on establishing small communities and organizing entertainment activities is currently carried out in order.

Fuel Banks

Despite having power plants to provide energy for the city, there are still fuel banks of various sizes in the city. Usually, the ultracapacitors and other power storage facilities in the city are available for emergency, making it surprising that such amount of fuel banks exist in City-δ.

The fuel stored in these banks is not completely useless, as some of the blueprints used to make high-energy explosives need it. Therefore, the M.E.O.D. and other cooperating groups are willing to open some of the fuel banks to wanderers with needs and permissions, while ensuring their safety.

The top of the fuel banks is painted with the gigantic logo of Corporate Co., and the commander of all fuel banks is named Process-56, as expected.

Non-Tokamak Nuclear Fusion Power Plants

The supplies adequacy of the non-Tokamak nuclear fusion power plants is relatively limited, but as the structure that supply power to all buildings in the level, their strategic value is of great importance. Although these power plants use nuclear reactions for energy supply, their stability and safety are rather reassuring. They cannot be easily destroyed by force, preventing chain nuclear explosions.

Livability——2

Population Density——1

Reactor

The actual size of the reactor is not that large, with the largest structure being a triplet cooling tower, used to cool the high temperature helium gas and steam.

Currently, no group has the intention of opening the core of the reactor, as it would result in disastrous consequences. Also, due to its extremely solid inwall, the core cannot be exposed, which guarantees the safe operation of the power plants. However, transmission spectrum detection from outside the core has proven some information about the internal conditions of the reactor: the magnetic field intensity inside the reactor is almost the same as that outside, indicating that there is no Tokamak limitation device in the core. Instead, another power system is used to make fuel pellets release energy in the void generated by an unknown device.

There is a storage room in the southeast corner of the reactor, where a dark green, unknown viscous liquid is stored in large glass jars, whose ingredients are extremely complex and cannot be completely analyzed. However, according to the notes on the jars and manuals, the liquid is named blockers, which is different from moderators or control rods that appear in common nuclear power plants. According to the information in the manual, it can be inferred that the liquid can not only slow down the nuclear fusion reaction, but can also completely stop the nuclear fusion reaction when a large amount of blockers are added into the core. The blockers have extremely excellent performance and can unboundedly diffuse in the vertical direction, forming a molecular curtain wall that blocks the nuclear reaction.

Substations

Substations are widely distributed around the reactor, mainly used to reduce the ultra-high voltage outputted by the nuclear fusion power plants before inputting it into the ultra-high voltage transmission corridors, which then transmits power to other PMMA spheres. Other than acting as transformers, the substations can also bridge-connect the transmission corridors to other PMMA spheres.

The substations will become extremely unstable when encountering disasters in the level, causing leakage in the transmission corridors and producing native Plasmaniacs. Under normal circumstances, the internal step voltage is also extremely high. At the same time, there may also be some valuable industrial machinery blueprints inside, which can only be explored by professional teams with specialized equipment.

Transmission Corridors

The transmission corridor,strictly speaking, does not belong to the non-Tokamak nuclear fusion power plant, but because the power plant is the beginning end of the transmission corridors, acting as the key node of the transmission network, it is classified within the scope of the nuclear fusion power plant.

The transmission corridor is a type of virtual pipeline that employs a wide-range infinite transmission mode under an unknown force. To mark out that the air in the area contains high-voltage power, there is virtual light rings around the pipes that will change their color according to the maintenance status of the transmission corridor:

⬤——Normal Operation; No Leakage

⬤——Abnormal Operation; Black-out

⬤——Pipeline Damaged; Slight Leakage

⬤——Complete Fracture; Severe Leakage

⬤——Currently Maintained by Fore-keepers

Waste Spheres

Waste spheres refers to all types of PMMA spheres in the level that have suffered severe damage. The PMMA domes have lost their function of isolating their contents from heavy water rain and waves. Usually, pipes extended from the seabed can be found around the spheres, and Sharkopards are often observed there, seemingly collecting supplies by entering from these pipes. However, exploration by volunteers has implied that these pipes are all solid structures and cannot be entered, but some assumed that Sharkopards enter the waste spheres by no-clipping into these columns.

Most of the plants within the waste spheres have been dried-out, leaving an area of yellow-brown debris. Meanwhile, under the radiation of heavy water, vine and other herbaceous plants are the most prone to mutation, growing wildly inside the spheres under the nourishing of heavy water, to the point where they cover the top of the dome, block the sunlight, and make the inside of most waste spheres look gloomy. Small groups of wanderers are almost completely outgunned when facing the advanced groups of Sharkopards under such harsh conditions, so it is recommended that wanderers do not get into waste spheres for supplies.

Locked Information 2 - Overview of Heavy Water Sea Structures:

Generally speaking, wanderers who no-clip into this level will appear inside the PMMA spheres, but there are also a few unlucky ones appearing in the heavy water sea structures. This often results in a significant increase in the survival difficulty during the early entry period, but understanding the characteristics of these structures and the distribution of supplies can help you evacuate to the safe zone inside the PMMA sphere in time.

Sharkobay

Sharkobay is the only open structure on the heavy water sea that has an actual ground. The main body of Sharkobay is a heavily weathered reef with a large gap at the larger end, forming a natural deepwater port. The reef has a layer of fine sand paved on the bay mouth due to the high degree of weathering. Sharkopards often converge here and use it as a transfer station, setting up material storage points. When Sharkopards cannot be observed on the reef, a small amount of food supplies and ammunition for their shotguns can be found in the iron plate boxes they use to store materials.

A stranded yacht may be found in the southeast corner of Sharkoay, and some parts can be found in the storage box at the rear engine. One can repair the yacht according to a specific blueprint with the M.T.S.G. and quickly escape from Sharkobay. In addition to the parts, a pistol can be found in the storage box. The model of the pistol is unknown, but its firing method indicates that it was designed after the 1960s. The magazine of the pistol is half full and the safety catch is not on.

If you are in a bad situation and cannot find the yacht, just try to find a shabby tin hut at the end of a trail in the jungle of the reef, where you can find extra food supplies. After settling down, do not approach the Sharkopard’s camp and stay inside the hut until the Steel Bustard lands on the reef. The M.E.O.D.'s “Parachute Project” has been implemented for about half a year. We use blue Steel Bustards to drop life rafts to heavy water sea structures such as Sharkobay, and you can use the maps on the rafts to go to the PMMA spheres where the M.E.O.D. and cooperative groups are located.

Observatory/Turret

The observatory/turret is a type of structure with great strategic significance. It appears to be a lighthouse, but the difference is that the top of the tower is replaced by a unidirectionally transparent spherical dome.

A mechanical device similar to a low-resolution astronomical telescope protrudes outward from the top of the tower. The device can indeed be used as an astronomical telescope at night. However, when the internal timing system detects that it is daytime in the level, it will switch to firing mode to complete the transformation to a turret. After the transformation, with the power supply from the power plant, the turret can accurately attack sea targets within 800 meters around the tower with high-explosive shells with a caliber of 84mm by electromagnetic ejection. These high-explosive shells come from the ammunition bank at the base of the tower, and the replenishing process in the bank is parallel to the transformation process of the observatory/turret.

Considering the increasing mechanization level of Sharkopards attacking PMMA spheres, the M.E.O.D. is currently trying to find more observatories to conduct sea monitoring and defense work, and to destroy the Sharkopard's yacht squads that appear outside the attack range of coast defense forces.

Sea Stronghold

The sea stronghold is a sea platform controlled by Sharkopards to connect their submarine bases and the sea surface, and to assemble forces to attack PMMA spheres.

The sea stronghold appears to be an open and dilapidated sea drilling platform. Multiple harpoon ejectors are placed above the platform to accurately destroy rafts and yacht engines. Multiple simple frame-style watchtowers are also built near the drill rig, with Bombing Sharkopards and Shotgun Sharkopards patroling above.

A certain part of the platform was smashed open by the Sharkopards to form a deepwater port to accommodate their yachts and rafts. The entrance to the port is blocked by fishing nets and steel plates. Currently, we have only received one report from a wanderer who appeared next to the sea stronghold when they no-clip into this level. They seized the opportunity to send a report before being thrown into the heavy water sea by a Sharkopard, and then the M.E.O.D. quickly contacted the troops stationed inside the nearby PMMA spheres to suppress the stronghold. The troops discovered that the internal pipelines were the same as those in the waste spheres, all solid columns that can only be no-clipped in/out by Sharkopards. We appreciate the contribution of this wanderer at the end of their life.

Unknown Coordinate

There are various opinions on the actual use of the unknown coordinate, among which the most likely three hypotheses are:

• The center point of the Sharkopard’s submarine bases
• The location of some sort of “core” of the level's running
• An unknown “distress” signal

Currently, we have no way to track people missing in the unknown coordinate due to the mental hazards of the level, nor do we know the specific location of the unknown coordinate, even if we obtain relevant coordinate data.

Subject: New Discovery on Measures for Sharkopard Innocuitization

---

To our honorable Dome Governance Committee:

This is Dr. Havoc. We have made proper arrangements for the innocuitized Sharkopards found by your committee and conducted comparative study on the components inside their bodies with those of ordinary Sharkopards. Four months ago, we made a list of suspicious components and compared the analysis data of the samples of captured Sharkopards with the components of innocuitized ones, from which we discovered a new compound called Manicormone. This compound can affect the Sharkopard's behavior, giving them strong pillaging, even hunting desires even without an established social structure or sufficient resources

After conducting a thorough investigation on the source of the innocuitized Sharkopards, we have identified a substance that is almost abiotic and has innocuitization capacity - blockers. Yes, when we discovered this group of non-aggressive Sharkopards, they were covered with this kind of dark green liquid. After several experiments, the P.R.I. finally proved that blockers can accelerate the degradation of Manicormone in the Sharkopard's body. However, we still need to find out where the Manicormone comes from.

At the same time, I will show you a new plan to deal with these Sharkopards in the appendix: in brief, we can try to use blocker aerogel to decrease their aggression. In order to speed up the extraction of blockers, we need more equipment. We hope to request more laboratories from the D.G.C., and we promise to keep you updated on the latest research results.

FILE——002——Invasion Report from the Blocking Squad "Astronomers":

Sharkopard Invasion Report

---

Abstract: Recently, Sharkopards are witnessed remarkably more frequently on the sea, and the number of yachts has also increased. Some Sharkopards' weapons are now equipped with universal optical sights, and some Shotgun Sharkopards have learned to use canned explosives. The defensive pressure on the observatory has increased, and we request that the headquarter increase our supplies.

---

Invasion #1:	Small-scale invasion. The weapons and tools used by the invading Sharkopards have been significantly upgraded, and all the Sharkopards take yachts to approach the coastline of the PMMA sphere. Fortunately enough, we destroyed all of them in time. Four yachts were destroyed in total, and the observatory was hit in explosion, but no real damage was caused.
Invasion #2:	Small-scale invasion. Sharkopards tried to use yachts to tow a sea operation watchtower. We tried to puncture its riveted joint, but the joint was incredibly solid. After the battle, we found the wreckage of the yacht and the watchtower embedded in the foundation of the observatory, and the trace of jointing matched the trace of the steel plate processed by the M.T.S.G. One yacht was destroyed, two Sharkopards were shot dead, and one yacht escaped. Now we've got evidence to suspect that there are humans colluding with these Sharkopards.
Invasion #3:	Medium-scale invasion. They used the same jointing technology to construct a new type of operation platform towed by four yachts, carrying Bombing Sharkopards. We took pains to destory this platform. However, several detachments of Sharkopards seized the opportunity to bypass the occupied platform, but they are annihilated by the coast defense forces.
Invasion #4:	Large-scale invasion. We don't know how their quantity of equipment have grown this fast during this period, even their yachts also seem to have become more solid. However, we have not seen any humans joining them. We assumed that these traitors are hiding behind the background and providing them with weapons and technical support! Two observatories have fallen by now, but no Sharkopards can control the turret, which is truly a lucky miss. We will soon get them all back. We are in an emergency situation; we cannot report any details of the battle for the time being.

Note from the D.G.C.: The “Astronomers” squad was encircled by a large number of Sharkopards and completely destroyed during the fifth large-scale invasion. Eventually, the coast defense forces made efforts to resist their operation. We hope these brave souls can rest in peace.

Emergency Status Activation Announcement:

To all residents under the protect of the domes:

Considering the increasing rampant activities of the Sharkopards recently, the frequent loss of turret defense forces, and the fact that some Sharkopards have even started to attack our cities, all PMMA spheres governed by the D.G.C. will be blockaded in two days, during which we will set up checkpoints and blockade devices in each corridor connecting the PMMA spheres. Please stay calm and receive your supplies in order. We will inform you about the specific evacuation location later.

FILE——004——D.G.C.'s Resolution on Dispatch of Special Investigation Team:

Voting Result of the 14th Emergency Conference
After comparing with previous proposals: large-scale use of blocker aerogel and mobile forces to eliminate Sharkopards, large stock of explosives, and even level transfer, we found that the success rate of the above proposals is not optimistic. Most of the exits in the level have been invalidated, and we have lost 34 PMMA sphere stations in the heavy battles, while the total number of evacuees by now accounts for only 7%. We cannot afford any more losses. We need tough medicine to immediately eliminate the flooding Sharkopardical invasion, and the only feasible solution is to destroy the source of Manicormone.

Dr. Havoc’s latest findings show that the unknown coordinate is the source of Manicormone. If we can destroy the source, the aggression of the Sharkopards will completely falter in 3 to 4 days. After several debates, we decided to transfer some combatants, volunteers, and researchers into the “Argonaut” investigation team, and use our last few large yachts to send them to the unknown coordinate.

The voting result:

YEA	ABSTAIN	NAY
41	1	38

In the next few days, we will recruit a total of 20 members for the investigation team, dividing them into teams α, β, γ, and δ to head to the unknown coordinate from different directions, and the equipment will be distributed correspondingly to ensure that each team can handle specific events independently.

FILE——005——Log Summary from Team Argonaut-α:

Team-α

[21/11/2049]

Captain of Team Argonaut-α reports.

We successfully bypassed the blockades of the observatory taken over by the Bombing Sharkopards. The other four members are in good condition. We saw an operation platform cruising at around 9 a.m, but fortunately we did not run into it.

Our speed is too slow, and the aerogel in the rear seriously hindered our maintenance work on the engine. I’m thinking about getting rid of them.

[24/11/2049]

Captain of Team Argonaut-α reports.

We seem to be heading towards the central zone of a large PMMA sphere containing a large number of deactivated nuclear fusion power plants. There are lookout Sharkopards shooting at us on occasion, and several domes have been blasted. I don't know where the fuck they got those powerful explosives.

A City-β we passed by seemed to be sinking because the Pit Hotel has been taking in water. The fore-keepers were still having a tough battle with the Sharkopards, but I don't think they can hold on much longer.

Mission in hand, gotta move on.

[27/11/2049]

Malena died.

Early in the morning, we found a group of Sharkopards attacking us with new explosives. Despite the strength of the hull, we didn't expect that the explosive didn't aim at our yacht at all, but instead sputtered yellow-green phosphors after the explosion, and we were all covered in the phosphors, becoming sitting ducks in the dark.

We set up covers in time, but Malena was unable to dodge and got shot. We tried to save her life, but all we could do was watch her bleed to death.

After we repulsed those Sharkopards, we sorted through Malena’s relics- one of which was a photo of her daughter. I'm just an ecologist, to be honest, and being appointed in this crisis did sound honorable, but it actually made me realize that I am a terrible leader. I should have arranged her in a safer location, moreover, she has gone through less training than I have.

We cannot afford to lose anyone else.

[02/12/2049]

We have been through a tough battle during the day, and Rick was seriously injured, but no life threat. I am writing down this log during a short break at night.

We have been encircled by the Sharkopard's yachts, but we quickly shook them off. However, our yacht crashed into the sea stronghold while we were dodging their bullets. Their firepower grew even stronger, however, thanks to the blocker aerogel, we were able to escape the stronghold in panic under the cover of cluster bombs and the dark green smoke.

The windshield of the yacht was destroyed by the explosion, and we need to find something to repair it, otherwise the heavy water rain will madden us all! Besides that, we need to vacate an area for Rick's recovery.

[04/12/2049]

The visibility on the sea was really poor, but at least the Sharkopards did not come for us.

We experienced the heavy water rain at noon, and I finally understand the wonder of heavy water. The sound of it hitting the metal foil is like pearls of various sizes hitting a jade plate, clear and melodious. We lit a fire next to Rick to keep him warm, then I roasted some Baobab fruits for lunch. Ivan was beside me, still leafing through his beloved botanical dictionary. C'mon, we're in the Backrooms, for fuck's sake.

As an ecologist, I have never seen such tough battle. In my initial opinion, any technology should exist for the purpose of building a peaceful and tranquil homeland, and now I understand it's also for wars.

I hate violence, but when it comes to necessary evils, I will…

If this is the only way to achieve peace and coexist with these entities…

I will do it, even if it puts me in a dilemma of morality.

[14/12/2049]

The fog on the sea has not lifted. I am a little delirious, maybe because the fog contains heavy water and Manicormone, or maybe because I have been thinking too much in the past few days and haven’t been able to have a good rest.

Rick is feeling better and can hold his gun now, but he still can’t walk on his own, so we arranged for him to do logistics. He has always been with that pile of plastic boxes. The problem worrying me most now is that although our direction is correct, we cannot make sure whether we will encounter another ambush of Sharkopards on our way.

[18/12/2049]

The number of Sharkobays and observatories around us has been growing, but fortunately no Sharkopards were there. We have found some shells from multiple observatories, but we don’t know how to use them yet. It is surprising that we do not even have the technology to easily modify the detonator of the shells like the Bombing Sharkopard does.

Rick can walk carefully on the deck now, but still cannot take any drastic action.

[23/12/2049]

We can vaguely see what is at the unknown coordinate through the thick fog. I will get the yacht closer for further observation, but I have been sure that it should be a non-Tokamak nuclear fusion power plant, with thick fog covered with a light pink PMMA sphere. If the thing we have to deal with is really here, the situation may become thornier. Nevertheless, we have prepared for the worst.

We have reached the shore, and I plan to leave Rick and Ivan on board, while Sterling and I enter the power plant to investigate separately. Wish me luck, I'm masked now, and we will go deep into the fog.

FILE——006——Log Summary from Team Argonaut-γ:

After Team-α departed, Beta, Team-β,γ, and δ departed simultaneously from the command’s south coast to investigate the unknown coordinate. Two days after departure, the three teams were ambushed by the Sharkopard's sea platform. After a tough battle, all personnel in Team-β and δ died, while three members of Team-γ died. According to subsequent documents, the survivors finally arrived the unknown coordinate, but no audio logs were sent to the headquarter from Team-γ after the battle.

Team-γ

[23/11/2049]

Penrose, lieutenant of the M.E.O.D. "Astronomer" reserve team, reports.

As scheduled, we will depart together with Team-β and δ, and after arriving at the supply center of City-δ-27, we will head toward our respective directions. Everything's fine now, we are all good. We are grabbing our minutes checking our equipment at hand now, and given the path we are currently on, I think we can arrive at the unknown coordinate before Team-α as expected. The formed preparation plans we have include detonation, suspension, and calling for reinforcements, and I have backed up all the plans on my laptop.

48 knots, downwind. We set the flying jib and went full speed in the afternoon.

[28/11/2049]

Team-β arrived two days later than expected, seriously dragging our feet. Despite this, we finally found a large amount of fuel stored in the fuel bank in City-δ-27, and now we are able to move on.

Nothing abnormal happened at noon. The cook of Team-δ boarded our yacht under my permission, asking to exchange some blockers for our compressed drinks. Considering the surplus of compressed drinks and the need to reduce the weight of the yacht, we accepted this exchange.

A placid night. I saw through the binoculars that the members of Team-β were playing poker with the lights on. My intuition implied me this was not a good habit.

[29/11/2049]

We were attacked by the Sharkopards' yachts! I knew those guys from Team-β would drag us down!

The bow of their yachts was equipped with some kind of cannon, and all of the teams' boats were hit several times. I was puzzled as there was no signs of shaking or leakage. However, we soon realized we were hit by yellow-green phosphors, and our location was completely exposed! Their firepower was times stronger than ours.

The battle was over, but I am still hiding in my own cabin. I couldn't contact members of other teams on my phone. The signals from β and δ have completely gone; they… probably have been destroyed.

[04/12/2049]

The food in my cabin has run out, so I have to return to the deck. Hope I can escape this time.

The deck was empty. No signs of battle except for the shells, bloodstains and phosphors. It seems that β and δ blocked most of the firepower for us. I need to check whether there are survivors.

Found him! Exley's here! He has been hiding in the cab.

Exley was shot in the right leg, fortunately the injury was not that serious, but it still needed dressing. We'll go on our way; hope these residents can hold on.

[12/12/2049]

My head is… spinning… feel like someone is grabbing it. Have I been affected by the mental hazards?…

Exley said he could hold on for some minutes and urged me to rest. I think I really needed it, so I went back to my cabin under the deck to have a nap.

…Where am I? Uh, the cabin. We need to go to the Shrine at full speed.

[13/12/2049]

The Shrine is calling me. I can see its pink light from afar, so dazzling, like a raging pink inferno.

I paced around on the deck and saw another person pacing there - Exley, a mediocrity ignorant of his destiny. But soon, the Shrine will grant him evolution.

A voice in my head has been implying me about the key to return to the Frontrooms stored in the Shrine. Well, a great mission has been given to me, so I will become a prophet with alacrity, guiding everyone back home, ha!

[15/12/2049]

Exley started to look at me with a strange look in his eyes, but I won't blame him. His brain structure is far different from that of the faithful followers of the Santuary like me. I will try to explain the existence of the Shrine to him.

I displayed my skills a bit in the evening. I haven’t tried a punching bag for a long time, but Exley fitted right into it. I sacrificed this betrayer’s blood to our sacred heavy water sea - the Mother Sea, causing a slight ripple. It seems that the guide of the Shrine really enjoyed it.

I feel the guide has an imperial edict to convey to me. I can’t wait to meet him in my dream.

[18/12/2049]

I still clearly remember the inspiration given by the guide in my dream. I understand that I must find the K’awiil Jar in the Easter Sanctuary in the Shrine, and the black slurry inside can tear open the gate of homecoming in the Shrine.

I will I will I will I will I will I will I will, my supreme home guide.

This is gonna be my last time recording this fucking niggling audio log, so there's no need to be formal.

I’m sorry, Rick. Sorry, Sterling. And Malena ahead of me - I've promised you to keep out of this.

When we boarded this sphere covering thepower plants, I somehow had a sense of my fate. It’s interesting how human beings always see their own fate as it is and calmly face it.

We found another yacht at the landing point, and when I entered the reactor first, I saw another person - Lieutenant Penrose of Team-γ. When I wanted to call him over to help me investigate, he suddenly fired several shots at my feet, with a mad, twisted smile on his face. He seemed to have suffered severe mental hazards, maybe so have me, as I had a headache then.

He was yelling that he would get my blood as a sacrifice to the Sanctuary. After a while of playing cat and mouse, he knocked me down, tied me up, and then threw me into the lounge.

When I woke up, I found that my abdomen had been tied to the chair in the lounge. In front of me was a chess set from that most useless blueprint. He wanted me to have a game with him, and if he won, he would cut my belly open to take my blood; if I won, he would find another part of my body to take my blood. He fucking maniac.

I found no difference between the two ways, but I thought the second one had a higher chance of survival. So I chose to play this fucking absurd game of chess with him.

When I had his king surrounded, before I could yell out “you lose,” he gave a scornful smile and said, “Checkmate.” Then he grabbed his combat knife and slashed my wrist. I could only watch as the blood sprayed into that plastic box.

He poured my blood into the spittoon at the doorway, and the wall of the lounge slid open, exposing a sign with a colored light ring said “Easter Egg Room”. I almost laughed out. Was this the so-called - Easter Sanctuary?

Then he brought out a jar of black slurry - the K’awiil Jar he mentioned. This maniac said that it could open the door back to the Frontrooms. Didn't he realize that it was just a jar of Russian black caviar? A fucking absolute maniac. He took a little bit and wiped it on the wall, and then a hint of fishy smell made him realized the truth.

Thanks to this prank, he raged up and kicked me and the chair out. Then, in a deep growl, he shot himself in the mouth, and the chair also fell apart. I couldn’t waste a single second. I found a bunch of files marked “processes” in the control room, and the last process was the activation of the "Mania State". In short, I have to destroy this power plant.

It's possible to destroy it following the method in section 12, but we need something to block the chain explosion within a certain range, or the whole level would be fucked up. I preseted the meltdown device according to the operational regulations and told the three members outside to hang the blocker aerogel behind the yacht, take a loop around the sphere, and then evacuate I also told them I would leave on another yacht.

Then it came to my own curtain call. As I activated the Easter Egg Room, the self-destruct system of the center was broken, and I had to keep repeating the combination of keystrokes there.

There's no way out for me.

Uh, the meltdown degree is 92% now. Time to say goodbye.

94%…

At least I didn’t let down "Argonaut", the team's name, ha.

96%…

I didn't get the Golden Fleece like Jason did, but I don't care.

98%…

To have the “Sun” buried with me, how glorious.

99%…

Farewell, fellas…

FILE——008——D.G.C.'s Resolution on Establishment of Monument for Team Argonaut:

For Our Alliance
During the defense battle, Team Argonaut has made huge sacrifices. However, after destroying the power plant producing Manicormone, the Sharkopard’s offensive completely disintegrated within 4 days. We were left with only 14 cities in our remaining bases, and only 3 members of the Argonaut investigation team survived.

We honor the team for taking on all the risks, especially Captain Carlos of Team-α, who perished with the Manicormone generator. His spirit will become a bond that connects us to confront all sorts of challenges. Here we propose to establish a monument in honor of the heroes who participated in this operation.

The voting result:

YEA	ABSTAIN	NAY
38	4	0

Proposal approved.

Documents about the later discovery of Level 667:

Submitting the document modification request. The survival difficulty will be amended to 3E.

SURVIVAL DIFFICULTY:

Class 3E

• Unsafe
• Unsecure
• Non-Entity Hazards

After the explosion of the Manicormone generator, the overall environment of the level underwent a significant change. The external temperature of the PMMA spheres dropped, with an average temperature of -29°C, and the surface of the heavy water sea iced. The frequency of the appearance of Processes-29 increased, but with a lower threat. The mental hazards of the level have completely disappeared, and now we can have effective communication with Sharkopards.

Iced heavy water sea.

According to the data sent back by Carlos who sacrificed himself, the complete destruction of the Manicormone generator activated a new emergency process, causing changes in the level's ecology, and decrease of the overall amount of supplies in the level, but it is still enough to maintain the lives of the residents under the dome at present.

Due to the freeze of the heavy water sea, Sharkopards can no longer return to their submarine bases to obtain supplies, and their numbers are sharply decreasing. With the help of the P.R.I., we have successfully conducted meetings with some Lead Sharkopards and planned to relocate all Sharkopards to several vacant cities for refuge.

Despite the continuous controversy in the committee, we have still made it. After all, this is his last wish…

As an ecologist, I have never seen such tough battle. In my initial opinion, any technology should exist for the purpose of building a peaceful and tranquil homeland, and now I understand it's also for wars.

I hate violence, but when it comes to necessary evils, I will…

If this is the only way to achieve peace and coexist with these entities…

I will do it, even if it puts me in a dilemma of morality.

But when everything is settled down, I am willing to reconcile with them, as they are also struggling with their hands tied…
…

The first snow starts to fall slowly, covering the dome of City-α, where the headquarter is located.

Threads of sunlight converge together, projecting a dazzling beam on a newly established statue of the deceased. On the square next to it, visiting the statue are the Sharkopards recently arrived and the surviving residents after the disaster.

Redemption is not over; we must combine as one.

1. This form of PMMA appears to be doped with titanium dioxide microcrystals, giving it the ability to self-clean, resist dust, and repair itself. The PMMA layer has good transmittance.

2. Tokamak is a type of coronal or annular device. It achieves artificially controlled nuclear fusion reactions by using electromagnetic waves to push and restrain the fuel pellet during the reaction in order to generate a proper environment and an extremely high temperature for D-T fusion and realizes artificially controlled nuclear fusion.

3. That is Dome Theseus mentioned in the picture.

4. The majority of the vegetation relies on normal water to survive, although some mutant plants can also survive under heavy water and are typically found outside of domes.

5. In order to prevent chain nuclear explosions, non-Tokamak nuclear fusion power plants are fitted with brake devices that work on unknown principles.

6. No more than 14m/s.
