Lin Ye is an "ordinary" patient in the No. 7 Mental Hospital and is diagnosed with severe delusional disorder - he always says that he can see various "gods" floating above other people's heads. It wasn't until a strange rainy night when patients in the hospital began to disappear one after another that he discovered the secret hidden in this mental hospital: every madman here is a container for a fallen god. And he is the only one who can kill gods.
