Chen Xiaoliu, the eighteenth generation descendant of a run-down Taoist sect, was a dabbler in Taoism and sneaked into Jiangnan University to work as a night shift security guard in a work-study program. Unexpectedly, the first thing he did during the night shift was to bump into a female ghost, and be tricked by the underworld into becoming a demon slayer in the underworld - to be honest, he was still a temporary worker. Relying on three tricks and half of his family's kung fu, he led two cheating best friends to deal with campus supernatural phenomena while cooperating with the policewoman to solve the case. The salary is not much, and there are a lot of mistakes. After all, they are all working as workers, and it is not easy for them to be ghosts.
