Resources, Rewards, and Protection

Notable Incidents

Xu Ye's Examination

Xu Ye enters through the open examination after his special-pardon writ is taken by the Su Family. He passes the strength test, kills 120 demons in the Demon Prison within an hour, takes first place, and becomes a Black-Robed Demon-Suppression Guard 13 15 18 20 21.

Mu Family Town Intelligence Tampering

The Bureau dispatches Xu Ye's group to investigate disappearances in Mu Family Town based on Demon-Patrol Guard intelligence identifying the threat as a sixth-level Meridian Opening fox demon 41 47. The actual target, Xi'er, is a Qi-Control Realm demon with a mind-control technique, nearly causing the team's deaths 47 48.

Song Kai's investigation establishes that the original report correctly identified Xi'er's realm and abilities. A Bureau clerk altered the report after being bribed by Su Yu of Tranquility Hall 56.

Su Yu's Death

After Su Yu's role in endangering fellow guards is exposed, Xu Ye demands his execution. Xu Ye ultimately kills Su Yu inside the Demon-Suppression Bureau despite intervention from Gao Jie and Du Yuanxiu 58 60 61.
