Don't Stay in a Noisy Ward

The Anning ICU of Mingde Hospital on the outskirts of the city is not an ordinary medical institution, nor is it a single mental experiment site, but a closed prisoner game field built with intelligent acoustic systems and hierarchical artificial screening. All deaths, weirdness, temptations, and good intentions in the hospital are a screening system that has been running for ten years, iterated at every level, and controlled by humans. There are no random accidents, no natural evil, and everyone is a player in the game and the planner.
