An ordinary young man, Lin Ci, was forced to bind the system and run a haunted house connected to the abyss. His "employees" are all real ghosts: the schoolgirl in red, the weird suture doctor, etc., All show their magical powers and scare customers out of their wits, but they are thought to be otherworldly experts because of their excessive "dedication". Lin Ci used this to collect fear energy and expand his business territory. From opening branches and establishing ghost pawn shops, to cooperating with the government and taking in refugees from other worlds, he eventually developed the small haunted house into a terrifying holy place across the multiverse. In this ridiculous venture, he also grew into the real "Lord of the Abyss."
