Lin Mo, a social animal, is drawn into a different-dimensional survival game by a scarlet invitation. He and strangers travel through dungeons such as the Silent Sanatorium, the Time Loop Town, and the Mirror Maze. Each scene is closely linked to the deepest fears of human beings. Survival depends on abiding by the rules of hidden murderous intentions.
On the edge of life and death, Lin Mo met Su Qing and others, witnessed betrayal and sacrifice, and gradually discovered that the "rules" are a screening experiment of high-dimensional civilization that feeds on fear. They went from following the rules to survive, to exploring loopholes, and finally faced the source of fear. This game is a battle for survival, but also a confrontation with oneself - only by accepting the fragility of one's heart can one break free from the shackles of rules.
