When Lin Mo woke up in a ward covered with blood, he found himself involved in a strange survival game. The rules imprinted on the wrist are the only guide to survival - "You must stay in the ward after 10 pm", "You must bow your head to say hello when meeting a doctor", "You must not enter the special ward on the third floor"... There is a murderous intention behind every rule, and violators will face unimaginable horrific punishments.
Fortunately, Lin Mo accidentally awakened the "Rule Eraser" ability and was able to see hidden loopholes in survival. The secret of the doctor's work card, the trap of the potion in the nurse's station, the loose chain at three o'clock in the morning... He moves step by step in the thriller dungeon, establishing alliances with other players and hiding suspicions.
As the gear mark gradually became complete, the secret of "Source Power" in the experiment log surfaced, and Lin Mo discovered that behind this game, there was actually the truth about the human experiment thirty years ago. When the rule-maker appears in Ward 307, he must make a choice between obeying the rules or breaking them, uncovering the ultimate conspiracy of the survival game.
