Mandate and Jurisdiction

The imperial court established Demon Suppression Bureau branches in every county to resist the threat of demons and evil cultivators. Their stated duties are demon extermination, bandit apprehension, and preserving the Great Yan Dynasty's local stability 8.

Tianshui Prefecture's Bureau is one of the prefecture's four top-tier powers, alongside Famous Sword Villa, Puzhao Temple, and Flood Dragon Palace 83. Its presence serves as a principal counterweight to the Flood Dragon Palace and other major demonic forces operating around the Tianshui River 205.

Facilities and Resources

• Training grounds — Headquarters maintains an open-air training ground where officers may spar privately, provided nobody is killed and future missions are not impaired 102.
• External Affairs Hall — One of the busiest locations at headquarters, surpassed in activity only by the training ground 102.
• Armory — Officers can exchange Armory Secret Tokens for martial arts and cultivation techniques 13.
• Exquisite Pavilion — The deepest section of the Tianshui armory and its core treasury; even Spirit Sea Venerables cannot freely access its treasures 227.
• Inheritance Secret Realm — A Bureau-controlled inheritance site used to cultivate exceptional young talents such as Gu Cheng and Tang Lingyu 100.
• Lifespan Extending Pills — The Bureau possesses exceptional wealth and reportedly monopolizes most pill formulas that extend lifespan, making these rewards a major means of attracting allied talents 100.
• Emergency identity tokens — Officers' tokens can emit a blood-red warning signal during life-threatening emergencies 203.

Policies and Methods

Recruitment and Talent Cultivation

The Bureau rewards demon-slaying achievements with promotions, martial arts, Armory Secret Tokens, rare treasures, and Lifespan Extending Pills. Its leadership emphasizes that officers who follow assignments and diligently eliminate demons will be rewarded accordingly 100.

It can tolerate unusual cultivation methods when they are used for demon slaying. Venerable Ling Que explicitly reassures Gu Cheng that exceptional individuals are not heavily restricted so long as their power serves the righteous purpose of eliminating demons and monsters 100.

Treatment of Demonic Cultivators

The Bureau's policy is not uniformly exterminatory. It issued an information bounty for the mysterious “Blood Kirin” rather than a kill order, intending to recruit the powerful Demonic Grandmaster instead of treating them as an automatic enemy 133.

After learning that Blood Kirin could contend with two Spirit Sea Venerables alone, the Bureau cancelled the bounty as a gesture of respect toward a powerful individual it could not easily recruit 206.

Dark Division

A secret Yunzhou-based unit reportedly exists within the Bureau. Its members are Demonic Grandmasters who conceal their identities while handling clandestine and disreputable assignments across Yunzhou's twelve prefectures 133.

Enforcement

The Bureau is known for harsh, highly visible enforcement during major operations. During a sweep in Changle County, resisting suspects were killed and their severed heads displayed on the city wall, rapidly restoring order through fear 75.

Its earlier prefecture-wide “great purge” targeted demonic forces such as the Blood Blade Sect, while established powers with long-standing friendly ties to the Bureau were treated differently 18 99.

Documented Operations

Tianshui Prefecture Great Purge

Three months before Gu Cheng's transfer toward headquarters, Tianshui Prefecture underwent a major Bureau-led purge. The Blood Blade Sect was among the principal targets, suffering heavy losses that left its Demonic Grandmasters largely eliminated 18 127.

Baihe County Water Demon Investigation

A headquarters team was dispatched to Baihe County after the Innate Azure Water Demon Ape disappeared and Mortal Breaking Realm demons began fighting for its territory, displacing local communities 86. The operation escalated when the Innate Dragon Turtle Jiao Wushang attacked and severely injured several Bureau officers 91.

Iron Cloud City Investigation

The Bureau investigated Rebirth Sect activity in Iron Cloud City after receiving a lead concerning the City Lord's mansion. Deputy General Liu Qingshan personally led the inquiry, accompanied by Huang Qiuyue 192.

After the Rebirth Sect's blood-sacrifice ritual devastated Iron Cloud City, Bureau commanders arrived to assess the destruction and learned that Blood Kirin had annihilated the Spirit Sea Corpse King and the remaining cult forces 199.

Crimson Rock Mountain Range Reinforcement

Hundred Beasts Villa appealed to the Bureau after repeated clashes with demons left it at a disadvantage and cost it two Innate Realm elders. Xu Wenying assigned Gu Cheng and Tang Lingyu to assist with the crisis 227.

Internal Problems and Threats

• Branch corruption — Some local branches are compromised or ineffective. Changle County's Bureau was described as corrupt and included personnel colluding with demons 14.
• Infiltration — The Rebirth Sect placed informants within the Chongshan County Bureau and used false intelligence to mislead its officers 178.
• Uneven local authority — Chongshan County's Bureau was overwhelmed by the region's demon population, leading locals to rely on independent Demon Hunters instead 154.
• Political constraints — Headquarters officers cannot act against a branch commander without irrefutable evidence, even when corruption is suspected 87.
• Loss of Venerable Yan Blade — The concealed death of Venerable Yan Blade weakened Tianshui Prefecture's balance of power and emboldened external demonic cultivators and half-demons 205.
• Pressure from rival powers — Famous Sword Villa's growing influence and the emergence of the Heavenly Sword Venerable forced the Bureau to weigh political stability against direct intervention 214.

Relationships

• Great Yan Dynasty — Founding authority; the Bureau serves as the dynasty's official anti-demon enforcement body 8.
• Flood Dragon Palace — Major regional threat and rival power. Bureau Venerables guard the Tianshui River against its Spirit Sea Flood Dragons 205.
• Famous Sword Villa — Traditionally maintains friendly relations with the Bureau, though tensions escalated into an open clash in Tianshui City 99 221.
• Hundred Beasts Villa — Regional ally that requests Bureau reinforcements when its Demon Servant cultivators cannot contain large-scale demon activity 227.
• Rebirth Sect — Primary hostile demonic sect responsible for infiltrations, blood-sacrifice plots, and attempts to divert Bureau attention 178 190.
• Evil King Pavilion — Hostile assassin organization whose activities create major security concerns for Bureau officers and leaders 212.
• Hundred Saints Valley — Half-demon organization exploiting the fall of Venerable Yan Blade to expand into Tianshui Prefecture 203.
