Background

Humans entered the Bunker only a few decades before the present story. Elderly residents still remember the outside world, including the sky and sea, while younger generations know them primarily through the Three Towers. 10

The Bunker originally consisted of only two layers: one Functional Layer and one Residential Layer. It has expanded as humanity explored the Three Towers, leading to speculation that tower exploration effectively “moves” the towers and may eventually allow the Bunker to reach the surface. 4

Its origin remains unknown. Sha Ruijing cannot explain how humanity entered a structure with no exit, suggesting that the answer may lie within the Three Towers Game. 4

Structure and Environment

The Bunker is a sealed, vertically organized settlement. At the time Wen Xishu receives his Level Six reward, it contains sixteen floors: eight Functional Floors and eight Residential Floors. Even-numbered floors are functional, while odd-numbered floors are residential. 17

Floor range / location	Function
Lower levels	Densely populated residential areas with comparatively poor medical and living resources. The Second Level is the lowest Functional Floor and serves many lower-level residents. 17 19
Second Level	Houses lower-level functional facilities, including a Level Four warehouse and Wen Xishu’s Level Six Hospital. 18
Upper functional floors	Concentrate Level Four and Level Five facilities, including many entertainment-oriented structures inaccessible to most lower-level residents. 17
Sixteenth Level	The highest Functional Floor and seat of the Bunker’s major power holders. It contains more than half of the Bunker’s Level Five and Level Six facilities. 19

The Bunker’s dome simulates a day-and-night cycle, producing strong daylight during the day and dim moonlight at night. 33

Animals and plants are maintained on Functional Floors, including a zoo. The Bunker’s residents can see the sky and sea only inside the Three Towers. 4

Society and Governance

The Bunker is governed through a rigid social hierarchy. Authority, identity, wealth, and status generally determine how high a person lives; upper floors receive better facilities and resources. 17

Exploring the Three Towers is the primary recognized route for social advancement. The Bunker maintains institutions intended to assess and assign citizens to suitable tower systems, including the Three Towers Academy, Three Towers Research Bureau, and Three Towers Game Allocation Office. 4

Major governing bodies

• Bunker Security Bureau — Handles security, interrogation, armed enforcement, and part of the Three Towers exploration effort. It has six branches; the Second and Sixth Branches are responsible for external affairs and tower exploration, while the other branches primarily act as Bunker guards. 20
• Bunker Administration Bureau — Oversees administrative functions and participates in resource distribution and public messaging. 19 21
• Bunker Elder Council — Can convene senior officials to address major changes in population, resources, and facilities. 19
• Bunker Health Bureau — Responds to public-health emergencies and administers medicine supplied through Bunker facilities. 19 21

The Level Seven Conference Room on the Sixteenth Level automatically produces data on population, health, birth and death rates, supplies, and Bunker structures, giving top officials a detailed view of internal conditions. 19

Social inequality

Lower-level citizens have limited access to facilities and suffer disproportionately during crises. During the epidemic, the passage from the Second Level to the Third Level was largely sealed, trapping lower-level residents while upper-level personnel treated containment as preferable to risking wider infection. 19

Although Three Towers exploration provides a theoretical path upward, the allocation system is vulnerable to favoritism. Well-connected citizens can receive altered physical records or preferential placement, while ordinary people may be directed toward more dangerous tower assignments. 3

Connection to the Three Towers

The Bunker’s continued survival and expansion depend on the Three Towers Game. Exploration can return material supplies, technology, equipment, and facilities, while insufficient exploration risks the Great Devourment. 3 21

The Bunker’s adult population corresponds to the total number of Login Devices. These identity-bound devices provide access to one of the Three Towers. 4

Login Device	Tower access	Notes
Black Watch	Strange Tower	Wen Xishu is restricted to this device when first entering the game. 4
Red Watch	Tower of Slaughter	Intended for combat-oriented climbers. 4
White Watch	Tower of Desire	Intended for people suited to fulfilling others’ desires. 4

Normal citizens seeking to switch tower systems must wait at least six months. The Bunker uses formal allocation institutions to prevent everyone from choosing the comparatively gentle Tower of Desire. 4

The Tower of Deception is particularly important yet feared: veterans entering it must begin again without their prior tower attributes, abilities, or sequences. This makes the Bunker more willing to send newcomers there than risk established specialists from the other systems. 4 28

Facilities

Bunker facilities are graded by level. Higher-level structures offer increasingly transformative capabilities, with Level Seven facilities possessing special functions beyond ordinary infrastructure. 17 19

Facility Level	Documented examples	Significance
Level Three	Construction Prison	Used alongside the Level Four Prison for detention. 46
Level Four	Warehouse; Prison	The Second Level warehouse receives Wen Xishu’s material rewards; the Level Four Prison holds serious offenders and former cadres. 18 46
Level Five	Various upper-floor facilities	Many are concentrated on high Functional Floors. 17 19
Level Six	Hospital	Facilities capable of significantly changing Bunker civilization; Wen Xishu’s hospital includes medicine and advanced medical resources. 17 18
Level Seven	Three Towers Academy; Conference Room	The Academy improves Three Towers exploration, while the Conference Room monitors major Bunker data. 17 19

Wen Xishu’s Level Six Hospital

Wen Xishu returns from the Tower of Deception with a Level Six Hospital and substantial supplies, placing the facility on the Second Level to serve lower-level residents. Its ownership display identifies him as the owner, though Bunker authorities quickly occupy and control the hospital. 17 18 19

The hospital’s medicine begins curing the epidemic within hours, and its equipment is expected to help the Bunker address future plague crises. 23

Major Events

Wen family case and Wen Xishu’s execution order

The Bunker sentences the Wen family to death for grave crimes. Wen Xishu’s execution is delayed after authorities conclude that he may possess information concerning his brother, Wen Chaohua, described as the Bunker’s most heinous criminal. 1 2

Wen Xishu is permitted to enter the Strange Tower because the authorities hope tower exploration will reveal a lead on Wen Chaohua. 3 4

Second Level epidemic

An epidemic spreads through the lower levels, affecting younger residents as well as the elderly. The threat of losing future tower climbers makes the crisis politically significant, while upper levels initially restrict movement rather than prioritize relief. 5 19

Arrival of the Level Six Hospital

Wen Xishu’s first Tower of Deception exploration produces Level Six supplies and a hospital, exceeding the expected completion target. The hospital’s arrival transforms the Second Level’s medical capacity and makes Wen Xishu a symbol of hope among lower-level citizens. 17 18 22

Senior officials debate whether Wen Xishu should be treated as an asset or interrogated for presumed links to Wen Chaohua. 19 20

Public campaign around Wen Xishu

Sha Ruijing organizes a publicity campaign presenting Wen Xishu as the “saint of the Bunker,” its future, and a savior of lower-level citizens. Public gratitude helps raise the political cost of executing him after his return. 22

Security Bureau interrogation and rescue

Despite his contribution, Wen Xishu is interrogated with a lie detector and truth serum by the Bunker Security Bureau. Albert Napolitano ultimately rescues him with Liu Jinsen and agents from the Security Bureau’s First Branch. 20 26
