Authority and Mandate

The Demon Suppression Bureau was founded by Great Tang's Grand Ancestor Emperor to oversee demons and monsters under heaven. Its officers may execute first and report afterward under imperial authority. 102

• Slays demons and exterminates monsters; this is described as the Bureau's central rule and duty. 20 26
• Investigates anyone colluding with demons, including civil and military officials, nobles, and martial sects. 20
• Holds authority above ordinary officials and laws: it may oversee civil and military administration and suppress the martial world. 20
• Patrol Envoys may investigate misconduct within the Bureau itself; for serious offenses, they may execute first and report later. 114
• Its work is dangerous enough that many talented martial artists prefer sects, wealthy households, or the army over enlistment. 18
• The Bureau formally values demonstrable ability and merit over family background; this principle governs promotion, though exceptional appointments can still provoke internal opposition. 18 37 159
• It may conduct large-scale searches and arrests in the Imperial City when demon-related threats require it, including operations targeting concealed rogue cultivators. 464

Organization

Central and Regional Commands

• The Demon Suppression General Bureau is based in the Imperial City of Chang'an. 20 158
• Great Tang has fifteen circuit commanderies beneath the main bureau; the Longyou Circuit Commandery manages demon-related affairs in Longyou. 20
• In Jiangnan East Circuit, the Suzhou Commandery General Headquarters oversees eighteen commanderies, each with a branch office and a Demon Suppression General. 161 163
• The General Bureau is led by a Commander-in-Chief, a position held by Bai Yulou during later events. 472 532
• Although Chang'an houses the General Bureau, its permanent martial strength is comparatively limited because the capital's dragon qi suppresses ordinary demons; most experts above the Ink-Dotting Realm are deployed to circuits, passes, and border patrols. 142
• Regional Commanders are responsible for maintaining stability in their assigned regions, while retaining Patrol Envoy authority may allow them to travel and act independently when necessary. 207
• Jiang Yuechu was first appointed acting Commander of the Longyou Regional Command, subject to reaching the Lotus-Planting Realm and completing a General Headquarters trial. She later formally took office in Liangzhou as Longyou's Commander. 107 225
• The Bureau keeps case files on personnel; under its rules, these record important assignments, cultivation breakthroughs, and merit earned rather than every action an officer takes. 1009

Uniforms and Identification

The Bureau is identified by black fitted uniforms patterned in crimson, with a Horizontal Blade worn at the waist. These symbols are widely recognized by civilians, martial sects, officials, and demons alike. 3 20 41 57

• Black-and-crimson uniform — The standard attire of Demon Suppression Guards; later inspection ranks use black, white, silver, or gold robes. 3 20 158
• Horizontal Blade — Standard weapon issued to new guards; the black-iron blade is described as sharp enough to sever hair blown against it. 18
• Waist token — Bears “Demon Suppression” on one side and the holder's name on the other; exempts the bearer from inspections and permits unimpeded entry to and exit from Great Tang's cities. 18
• Silver Robe and Gold Token — Insignia issued to a Silver Robe Patrol Envoy. 159
• Cloud Bo / Cloud Tide mount — A one-horned, cloud-hoofed divine steed reserved exclusively for Silver Robe Patrol Envoys. 163 196
• High-ranking battle attire — Certain senior officers are identified in the field by blood-red cloaks and dark-gold beast-head pauldrons, which retain the Bureau's fearsome martial image even outside its standard uniform. 324
• Demon-Seeking Compass — A Bureau device that detects nearby demonic aura. Given a trace of a particular demon's aura, it can track that demon for up to a thousand li. 143

Recruitment and Benefits

The Bureau evaluates recruits primarily by ability and merit rather than origin or past offenses. 18 37

• New Ninth Rank guards receive five taels of silver monthly, three shi of rice, ten jin of meat, a standard Horizontal Blade, two uniforms, and a waist token. 18
• The Bureau provides compensation for injuries, posthumous honors for those killed in service, and free academy admission for dependent family members. 18
• Eighth-rank officers and above receive free housing in the Demon-Pacifying Ward; Ninth Rank guards may purchase homes there cheaply. 37
• Staffing shortages have led the Bureau to relax recruitment standards, accepting discharged soldiers and jianghu figures with useful skills. 35
• Promotion may include a formal promotion bonus in addition to elevated salary, rations, authority, and housing. 34
• A clerk describes a merit system in which slaying a String-Hearing Realm demon alone earns ten points and slaying a Bone Resonance Realm Great Demon earns one hundred; one hundred points qualifies a guard for advancement to Eighth-rank Team Leader. 19
• Martial arts manuals and opportunities for cultivation advancement may be awarded in recognition of exceptional demon-slaying merit. 89
• Despite its pay and benefits, frequent demon outbreaks, patrol requirements, and high casualty risk regularly leave the Bureau overstretched. 18 22

History

The Bureau's name carries a severe reputation throughout Great Tang. It is said that an Imperial Guard of the Demon Suppression Bureau arriving at one's door is like the King of Hell arriving; even children fear its name. 1

During Jiang Yuechu's early career, the Longyou Command lacked a Commander. The vacancy weakened the Bureau's standing against entrenched noble clans and sects, especially Jeweled Temple, which expected the Regional Command to show it deference. 102

The Bureau's authority was reasserted through investigations into Jeweled Temple's collusion with demons. Following the execution of monks Huiming and Huiyuan, the Longyou command received orders to investigate and execute any temple found to be collaborating with demons. 43 106 Later, Bureau forces mobilized to surround Jeweled Temple on Qituo Mountain. 229

The Longyou vacancy was ultimately addressed through Jiang Yuechu's appointment as acting Commander by the General Headquarters. After her subsequent advancement, she returned to Liangzhou and assumed the Commander's office, entrusting much of the region's administrative and military management to General Wei He. 107 207 225

When demons simultaneously rose across Jiannan and Longyou, the Bureau suffered severe losses and struggled to hold the line. More than half of fifty-four commanderies reportedly fell in a single night, and local Bureau offices were devastated. 316 317 Surviving guards later regrouped as Jiang Yuechu's campaigns reclaimed demon-held prefectures. 322

In later years, Liangzhou changed from a region plagued by demonic disasters into a peaceful, demon-free area under the Bureau's protection. Chen Tong, Liu Ke, and Bujie continued to serve there as Seventh-Rank Captains. 710

The Bureau remained active during a subsequent crisis in Chang'an. When a blood-red omen appeared over the city, civilians called for its officers, who mobilized alongside constables to respond to the public panic. 965

Relationships

• Jeweled Temple — A major Longyou sect whose protection of demons and defiance of Bureau authority escalated into open conflict and siege. 42 106 229

• Martial sects and noble clans — Subject to Bureau investigation when suspected of collusion with demons, though powerful local factions can challenge its practical authority. 20 41 102

• Jiang Yuechu — Rose from a Ninth Rank Longyou Guard to Team Leader, acting Longyou Commander, Silver Robe Patrol Envoy, and eventually Longyou Commander. Her exceptional advancement strengthened the Bureau's authority in several regional crises. 18 37 107 159 225
• Wei He — Longyou General who recruited Jiang Yuechu, defended the Bureau's authority against local powers, and later managed Liangzhou affairs under her delegation. 18 102 225
