Zhongli Jiuque, a new agent of the Demon Slayer Division, accidentally encountered the "Seven Star Life Extension Bureau" while investigating the Qinling Yin Mansion, causing his consciousness to merge with the remnant soul of Sikong Hui, the demon slayer of the Ming Dynasty. The two discovered that the resurgence of demons in 2025 is causally related to the "Civil Conflict in the Demon Slayer Division" 600 years ago. In order to prolong life, the great elder of the Ming Dynasty implanted a "bronze hexagram" in the core of the dragon vein, triggering a time and space paradox. Hope everyone will like it
