Seven days before the end of the world, Lin Yan received a text message from the future: Don't trust Su Mi outside the door. I have been killed by her six times. After zero o'clock, the city is dismantled into countless copies of the rules: schools become death examination rooms, hospitals only accept people without shadows, and midnight trains head for non-existent destinations. Lin Yan, who has returned from rebirth, has awakened as a hidden profession "Rule Editor". Every time he enters a dungeon, he can modify a rule, but at the cost of permanently losing a piece of memory. When he continued to rewrite the desperate situation and establish a survivor territory, he found that the one he had forgotten the most was Su Mi, and Su Mi remembered everything he had lost. It wasn't until the end of the world that Lin Yan discovered that the earth was actually an abandoned novel, and he was just a supporting character who should disappear in the first chapter.
