Purpose and Responsibilities

• Protect the sanctuary city: Inspectors are charged with containing Infection Sources and killing Infected, treating both as threats to the city's continued existence 285.
• Screen arrivals: Settling and inspecting migrants and refugees is an established Checkpoint responsibility, although its importance has been neglected during the city's development 128.
• Control entry and exit: Checkpoints use inspection equipment, isolation areas, guards, and automated defenses to screen traffic 24 28.
• Conduct field missions: Assignments include deliveries, reconnaissance, patrols, and cooperation with Inner City operations 48.
• Pioneer and preserve: The inspector's broader role extends beyond gate duty to opening up territory and preserving settlements 269.

The Checkpoint once formed one of Xingfu City's three principal branches alongside technology and the supernatural, controlling internal security while the other two handled development and external affairs. It later remains a distinct participant in high-level negotiations with the Tech Faction, Supernatural Sect, and Idealist Faction 128 138.

Background and History

Cheng Wu, Cheng Long, Xiao Shuntian, and Zhou Changhai are named in the leadership's account of the Checkpoint's establishment and development. Inspector positions can pass to descendants: Cheng Ye inherits his father's profession and becomes the third-generation holder of his family's inspector identity 2 270.

Xiao Shuntian becomes a notorious betrayer after losing his ideals during the Great Expansion era. Regan Carl kills him, and his punishment is memorialized through a black kneeling statue at the Main Gate rather than an inscription on the Station Administration Building's welcome wall 143.

By the restructuring discussions, more than 150 inspectors have defected from Xingfu City—more than the institution's remaining personnel. Zhou Changhai's infiltration by Star Ark exposes the weakness of a system in which powerful field inspectors largely rely on self-discipline. Cheng Ye's containment of the Immortal Relic prevents a catastrophe and helps avert immediate dismantlement of the Checkpoint 270.

Stations and Facilities

Principal Stations

Station	Documented Role and Features
Central Checkpoint	Houses the Station Chief Building and a field mission board. Its quarantine infrastructure is repaired after He Fei's death 48 92.
North Checkpoint	West Faction-controlled rapid inspection station, led by Downs, also rendered as Towns. Cheng Ye initially serves in Quarantine Zone A 11 27 28 34.
South Checkpoint	East Faction-controlled station led by Lei Hu. Liu Bi initially recommends it as the safer first posting for Cheng Ye 11 106.
Big Wave Town Checkpoint	Associated with Cheng Ye's developing settlement. Luo Kuke requests a transfer there after losing his legs and later helps guard its institutional boundaries 247 285.
Industrial Zone Office	A newly established Checkpoint office where Lei Hu meets with inspectors during the later institutional changes 282.

Quarantine Layout

North Checkpoint has six areas, A–F. Areas A–D form the front line, with E and F behind them 28.

Area or Facility	Documented Use
Quarantine Zone A	Inspects vehicles and quarantine convoys; includes warehouses, isolation chambers, and a garage 28 30 40.
Quarantine Zone B	Matthew Li's inspection post; also receives scavenger traffic 39 112.
Zone D	Contains a bathhouse used by Cheng Ye 280.
Isolation Chambers	Hold people awaiting inspection; Zone A contains 271 detainees when Cheng Ye tours it 30.
Charging Garage	Zone A has six charging piles. The fast-charging facility is subject to access restrictions, while slow-charging piles are reserved for checkpoint vehicles 28 29.
Research Branch	Handles Infection Sources and connects inspectors to the Xingfu City Infection Source Research Institute's mission system 32 70.

Security Procedures

• Isolation gates and disinfection: Entrants can be required to leave vehicles and pass through quarantine and disinfection on foot, even when their vehicle bears the Checkpoint emblem 85.
• Full lockdown: Following He Fei's death, North Station seals its checkpoints and prohibits entry and exit 39.
• Flag signals: Red indicates danger; white indicates the sacrifice of a duty officer. A yellow flag precedes the announcement lifting the lockdown 38 40.
• Yellow-line boundary: Crossing the line exposes personnel to exceptional danger. A stated duty exception involves rescuing Inner City Lords attacked within three kilometers of the Checkpoint 33.
• Infrastructure limitations: Central Checkpoint's post-disaster repairs use ordinary steel because stronger Isolation Alloy is unavailable 92.

Personnel and Advancement

Command Structure

Position	Authority or Function
Station Chief	Leads the institution; Ding Yishan also assigns Dongren field missions 48 270.
Deputy Station Chief	Senior command position held by Halin, who assigns Xiren field missions 48 212.
Duty Station Chiefs	Lead the rapid inspection stations. Lei Hu and Downs occupy the two positions 106 270.
Inspectors	Perform inspections, containment, and field assignments; their authority places them above ordinary station staff and guards 24 26.
Observers and Guards	Assist inspectors with local operations, detainees, and security. Raven and Owl support Cheng Ye in Zone A 28 118.
Researchers	Study and transport Infection Sources; Qin Feng serves at the checkpoint research branch 70.

Recruitment and Evaluation

• Hereditary entry: An inspector's descendant can inherit the profession, as Cheng Ye does after his father's reported death 2.
• Unpaid internships: The institution maintains an unpaid internship system for inspectors' children 24.
• First-posting assessment: A trainee arriving at the rapid inspection station must demonstrate sufficient ability. Downs gives Cheng Ye a passing score of 60 and issues his evaluation paper 25 27.
• Combat assessment: Halin's study session requires inspectors to kill an Infected within fifteen days 41.
• Survival-based selection: Rank advancement is fundamentally a selection process. An inspector reaching the third stage has generally survived at least three near-certain-death situations 234.
• Restricted Inner City access: Inspector status ordinarily prevents entry into the Inner City. Cheng Ye later receives a special quota of two entries every six months 4 248.

A disaster review records 52 distinct duty inspectors serving between June 6 and July 6 86:

Rank	Personnel
Fourth Stage	3 86
Third Phase	7 86
Second Phase	22 86
First Phase	19 86
Trainee	1 86

Internal Politics

East–West Division

• East Faction: Associated with Dongren inspectors and South Station; Ding Yishan controls its field assignments 11 48.
• West Faction: Associated with Xiren inspectors and North Station; Halin controls its field assignments 11 48.
• Mission patronage: Taking sides provides access to lucrative assignments, while neutral inspectors such as Li Maitai accumulate contributions through routine fieldwork 48.
• Temporary cooperation: The Starfish Doppelganger crisis suppresses factional conflict as both sides prepare to face the disaster 66.

Additional Factions

Faction or Outlook	Documented Position
Radical Faction	Mostly high-phase inspectors seeking to restore the Checkpoint's former glory and reclaim power 191.
Conservative Faction	Mostly high-phase inspectors advocating strong walls, stockpiled supplies, and patient preparation 191.
Academy Faction	Primarily low-phase inspectors 191.
Emerging Faction	Primarily low-phase inspectors 191.
Chuxin Faction	Holds that Buffer Zone residents and the Checkpoint's defensive line are mutually dependent and neither may be abandoned 96.

Privileges and Abuses

• Contraband tax: Inspectors benefit from a 30% price difference on certain goods, explained as compensation for accepting contamination risk 29.
• Dangerous discretion: A person deemed Infected can be killed immediately; an erroneous killing may require only a self-criticism afterward 10.
• Unequal treatment: Guards who initially dismiss Cheng Ye become deferential once they learn he is an inspector 24.
• Limited promotion opportunities: One Station Chief, one deputy, and two duty chiefs leave little room at the top, encouraging senior inspectors to seek influence elsewhere 270.

Major Institutional Events

Event	Consequences
He Fei's death	The Central Checkpoint chief dies from an Infected; North Station enters lockdown, and trouble handling his corpse causes further spread 39 47 53.
Starfish Doppelganger review	Entry records identify Garcia as the inspector who admitted the Mother Source Infected. The duty roster itself is found to comply with internal rules 86.
Empty Fog incident	Electronics fail and inspectors are isolated for about ninety minutes. Ant wolves appear in the quarantine zone after the fog lifts 110.
Migration expansion	The Checkpoint reasserts its responsibility for migrant screening and participates in plans for new settlements and facilities 128 138 146.
Satellite city construction	Inspector teams are assigned to outside settlements, with personnel arrangements balancing factional affiliations and rivalries 169 183.
Zhou Changhai's defection	A Fifth Stage Inspector leaves with seven others and key city personnel. Star Ark's involvement triggers renewed scrutiny and restructuring discussions 269 270.

Proposed Restructuring

Cheng Ye proposes separating inspectors into four functional paths to limit concentrated power and create clearer responsibilities 270.

Proposed Direction	Scope
City Defense and Duty	Guarding settlements, patrols, and maintaining the inspection line 270 285.
Field Operations and Trade	Wilderness operations and dealings with other sanctuary cities 270.
Containment and Research	Containing Infection Sources and pursuing research 270 285.
Overall Management	Coordinating the institution's functions and administration 270.

Border Inspector

• Qualification: Broad recognition and outstanding results across all four directions 270.
• Authority: A proposed position above Station Chiefs, with direct access to Xingfu City's high-level meetings and substantial influence over trade, research, and institutional affairs 270.
• Succession: Ding Yishan presents the role as an honorable future path for Cheng Ye, contrasting it with Zhou Changhai's flight 271.

Public Trust

Cheng Ye later recognizes that separation is necessary not only to curb power but also to preserve trust. Residents must be able to believe that patrol inspectors will keep Infection Sources outside the gates, even while a separate research branch studies them 285.

Luo Kuke's warning about Yu Yong illustrates the problem: many inspectors cannot accept cooperation with an Infected, regardless of mission needs or potential benefits. Revealing such cooperation could undermine confidence in the Checkpoint's protective role 285.
