Lu Mingyuan, an intern at a mental hospital, accidentally got involved in a death game called "Rules Trial". Every patient is a "player" trapped in the spiritual world, and the rules of the game will continue to twist with the actions of the protagonist——
High-energy reversal: The protagonist uses psychological knowledge to break the rule of "no looking directly at the person in the mirror", but the real murder scene appears in the mirror;
Survival challenge: By tampering with the rule of "taking sedatives three times a day", the protagonist gains extraordinary mental power, but it triggers collective madness among other players;
The ultimate puzzle: When all the players think they control the rules, the protagonist discovers that the source of the game is actually the "rule prototype" in the dean's brain.
