Xuanyuan Wujin was imprisoned in Qingshan No. 7 Mental Hospital, and everyone thought he was crazy. He said there are "gods" in the world who feed on people's fear and despair, and that he is the only "purifier." In the eyes of doctors and nurses, he was just a dangerous patient who shook his fists in the air and talked nonsense. However, when unexplainable and strange events began to occur in the hospital, and when people around them fell into the shadow of madness and death one by one, they began to suspect that this so-called madman might be seeing the truth of the world. When the boundary between reality and madness blurs, Xuanyuan Wujin must kill the gods lurking in the world and protect this fragile real world before he is completely "cured" as a madman.
