Qinghe Prefecture

Biodata

Geography and Cityscape

• Qinghe Prefecture is one of the thirteen prefectures under Anling Prefecture and ranks among its stronger prefectures in both land area and overall strength. 46
• Its prefecture city is heavily populated, commercially active, and inhabited by numerous martial artists; Qingxi County is considered comparatively small and lacking in high-level martial arts. 46
• The city walls are ten zhang high, built from blue-black granite with iron poured between the masonry. Its main gate is wide enough for four carriages to pass abreast. 50
• Ranked martial artists guard the gates. Even a gate squad leader possesses at least second-tier Tendon-Bone Realm strength. 50
• Major streets are lined with shops, wine houses, merchants, and street performers; the city remains active after dark, with entertainment venues inside the walls and music along the riverbanks. 50 51
• The Clearwater River sustains much of the prefecture's population and gives Qinghe Prefecture its name. 100

Guaizi Alley

• Guaizi Alley lies in the eastern part of the city near the docks, several li beyond the city walls. 93
• It is Qinghe Prefecture's cheapest district, populated mainly by migrant workers and laborers; its narrow, damp streets and dense low houses sharply contrast with the city's prosperous central districts. 92 93
• The Water Transport Gang recruits much of its manpower from the alley. 92
• Rumors of the Wedding Dress Woman and the discovery of pale, desiccated corpses drew Mu Yang to investigate the area. 92 93

Administration and Security

• Yuan Yin, the former Demon Slayer Bureau Slayer Commander, was regarded as Qinghe Prefecture's strongest individual while overseeing the local branch. After breaking through to the True Astral Realm, he transferred to Anling Prefecture. 122 254
• Liang Qing succeeded Yuan Yin as Qinghe Prefecture's Demon Slayer Bureau Slayer Commander. 254
• Shen Chongyuan, the Prefecture Constabulary's Chief Constable, is a fifth-tier Channel-Opening Realm martial artist known as the “Thunder-Galloping Blade.” 126
• Qinghe Prefecture officials, led by Literature Aide Fu Rui, responded to the Sancha County crisis alongside Demon Slayer Bureau personnel and prepared a replacement local administration. 152
• The prefecture's Demon Slayer Bureau directly assigns rare Earth-rank missions involving fifth-tier or stronger demons rather than placing them on its ordinary mission board. 132
• High-rank demon activity is comparatively uncommon in Qinghe Prefecture because discovered threats are quickly handled before they can cause widespread disorder. 132
