The world seems normal, but in fact it is a huge, recurring drama stage. The vast majority of people are "NPCs", unaware of the truth. A few "awakened ones" (such as the protagonist) can perceive the "scripted nature" and "reincarnation" of the world. They are called "actors". "Gods" are the directors and screenwriters of the stage. They feed on the emotions of all living beings (especially despair, fear, and hope) and carefully design desperate reincarnation scripts - "the final curtain." "Qingjiang City No. 4 Mental Hospital" is a weak point where the real world and the "Final Curtain" intersect. It is both a shelter and an entrance.
