Qin Yi, a 28-year-old high school mathematics teacher with rigorous logic and calm personality, was involved in the "rules game" after a night study hall. Participants need to abide by the constantly updated "death rules" in a closed space. Violators will die in strange ways. The price of obeying the rules is to participate in a high-IQ game. The winner can obtain "immunity" or get a glimpse of the truth of the game. There is a conspiracy of the controller hidden behind the game. Most of the participants are selected "high-value targets", and each other is both an ally and an enemy.
