Su Nian accidentally got involved in an infinite game called "Ten Days Rules". Each copy has strange rules, and once violated, it will be wiped out. In the first copy of "Midnight Campus", she relied on her keen observation and calm mind to break the rules such as "cannot stay in the classroom after ten o'clock in the evening" and "cannot look at herself in the mirror" and successfully survived. As the difficulty of the dungeon escalates, she meets the mysterious teammate Lu Yan. The two go from testing each other to fighting side by side, and gradually uncover the conspiracy behind the "Ten Day Rule". In the last copy of "Doomsday Castle", Su Nian not only had to face the most terrifying rules, but also had to fight against the mastermind behind the scenes. In the end, with her super strength and the help of her teammates, she broke the constraints of the rules and became the "God-Conferred" in the dungeon, leading the survivors to escape from the game.
