Background / History

The Imperial City Security Department is one of Great Yin's most feared institutions. It may supervise officials, act before submitting a report afterward, and is associated with the Emperor's direct surveillance through eunuchs serving within its ranks 385 388. Local government does not control it; even Wushui Commandery's Prefect cannot demand answers from it as though it were a subordinate office 591.

Its commandery branches form part of the Imperial Court's organized martial force. Their strength lies not solely in individual experts, but in disciplined personnel, intelligence access, resources, and the ability to mobilize official power throughout a region 347 430.

The department's remit includes managing martial cultivation resources. In Wushui Commandery, the County Martial Academy's cultivation methods, secret manuals, and elixir pills are kept under the department's control, preventing resources from being lost outside Imperial Court oversight 481. Promising local martial artists may gain access to its outer armory only after advancing through county and commandery-level arena selections 295.

During the spread of the Black Calamity, the department's higher echelons appear to have informed the Imperial Court's restrictions on movement between cities, balancing containment against essential commerce 357. Its personnel were dispatched to Qinghe County after suspicious incidents there, including the death of County Lieutenant Wu and possible Black Calamity activity 385 388.

Authority and Jurisdiction

• Imperial mandate — The department is authorized to supervise officials and, in appropriate cases, “execute first, report later” 385 540.
• Independent standing — It is specially empowered by imperial authority rather than being subordinate to local administrations 591.
• Military access — An Investigative Captain's token permits the mobilization of local troops, examination of classified archives, and summary action before reporting 545.
• Protection and deterrence — Eunuch Cao publicly invoked the department and the Imperial Court when promising protection for Fang Yuan's family, martial arts school, and associates 461.
• Resource control — The department uses Contribution Points to distribute cultivation methods and other valuable resources, allowing the Imperial Court to regulate access to martial advancement 482 549.

Organization

Command Structure

Position / Group	Known function or standing
Jiangyang Dao Chief Inspector	Highest-ranking Imperial City Security Department official in Jiangyang Dao; personally selects Investigative Captains 542 549
Chief Inspector	Head of a commandery-level branch. Shen Qianshan holds this post in Wushui Commandery 492
Inspector	An honorary inspection post with no fixed station or clearly defined rank; authority depends heavily on the holder's background and personal strength. Eunuch Cao holds this title 498
Investigative Captain	A Principal Seventh Rank post dedicated to Black Calamity investigations; its holders report directly to the Jiangyang Dao department rather than the local commandery leadership 540 545
Regular Captains	Personnel with fixed duties, daily roll call, and regular salaries, including gate guards and other stationed officers 544
Clerks	Maintain and sort case files, assist Captains with onboarding and missions, and receive rewards tied to successful assignments 544 556
Training instructors	Train recruits and lower-ranking martial artists; during the war crisis, some were transferred to the front lines 634

Investigative Captains

Investigative Captains are the department's dedicated Black Calamity investigators. The position grants exceptional authority but carries a high mortality rate, as its holders confront incidents that are difficult to understand, contain, or survive 540 576.

• They are appointed from above, potentially by the Jiangyang Dao Chief Inspector personally 542.
• They must accept at least one assignment annually to retain their post 544.
• Their principal duty is to investigate newly emerging Black Calamity incidents, which are considered less dangerous and more controllable during their early stages 559.
• Only Investigative Captains may accept missions through the Mission Courtyard; regular Captains instead use the Mission Hall 630.
• Chief Inspectors in every region must be selected from the ranks of Investigative Captains, making the role a potential path to senior command 542.
• The department provides no systematic induction training for Black Calamity investigation despite its resources, forcing many Captains to learn through lethal experience 576.

Facilities and Resources

Armory and Scripture Depository

The Wushui Commandery branch stores the County Martial Academy's cultivation methods and secret manuals in its armory and Scripture Depository 482. Access is regulated through Contribution Points and official authorization 482 504.

• The outer armory is a prize for martial artists who survive the layered county and commandery tournament selections 295.
• The Imperial City Guard Armory's Mysterious Zone is not a conventional armory but a repository for classified files. Within Wushui Commandery, only Shen Qianshan and Eunuch Cao are known to have access 498.
• The department's defenses are described as exceptionally thorough, with overt guards and concealed observers positioned throughout its grounds 482.

• High-grade resources and the True Bodies associated with them require substantial Contribution Point expenditures 549.

Story Role / Major Arcs

Qinghe County Intervention

Department riders led by Eunuch Cao arrive in Qinghe County amid fears of Black Calamity activity and the suspicious death of County Lieutenant Wu. Their presence alarms County Magistrate Liu Wenhe, who recognizes that the department's involvement signals imperial scrutiny 385 388.

Eunuch Cao subsequently orders arrests of selected suspicious persons, using local officials and Captains in Black Martial Clothes to carry out the operation 392.

Wushui Commandery Arrival

When Fang Yuan reaches Wushui Commandery City, four department Captains greet him at the gate due to Eunuch Cao's patronage 475 476. He then learns that the County Martial Academy and the department's resource system are effectively integrated under the latter's control 481.

Fang Yuan's Appointment

Following Fang Yuan's performance in the Martial Artist Arena, the Jiangyang Dao Imperial City Security Department appoints him a Principal Seventh Rank Investigative Captain 540. The appointment places him directly under the Dao-level department and grants him authority beyond local control, but also exposes him to Black Calamity cases 540 545.

Escalating Black Calamity Crisis

As Black Calamity incidents multiply around Wushui Commandery, the department's Mission Courtyard accumulates reports of disappearances and strange phenomena 547 556. Its investigative capacity becomes strained, with sects such as the Carefree Sect reporting that their cases were recorded but left unresolved due to insufficient manpower 631.

War Preparations

With the Rebel Army conflict worsening and Hanshan Commandery falling, the department shifts into an urgent military posture. Captains receive assignments involving provisions, troop movements, intelligence, and defensive arrangements, while even training instructors are sent toward the front lines 615 634.

Trivia

• The emblem on an Investigative Captain's dark-blue official robes depicts a sharp sword piercing a lotus flower 545.
• Department Captains are seen in differing uniforms depending on station and role, including black fitted clothes, green official robes, and dark-blue Captain robes 385 475 545.
• The department is widely feared enough that ordinary city residents avoid its gates, while its Captains can allow favored convoys to bypass normal city-entry inspections 476 591.
