Dressed as a gravekeeper in a haunted house, Lin Xu opened his eyes and was enveloped by the rules of death: if a ghost knocks on the door at midnight, he must remain silent, and if he answers incorrectly, he will die. His teammates were scared to death on the spot, but he smiled - not only could he see the hidden rules, but he could also forcibly tamper with them! When the evil ghost broke through the door with a ferocious smile, Lin Xu raised his hand and rewritten: "Gravekeepers are not allowed to hurt ghosts? Instead, evil ghosts must surrender." The ghosts screamed and knelt down, and the haunted house changed owners from then on. While others survive within the rules, he becomes king within the rules. The evil ghost worked, taboos were rewritten, and the entire haunted house became his private domain. Lin Xu has only one rule: from today on, I am the rule.
