The heroine Su Qing is involved in the world of rule-based murder and exile, and enters various horrific copies where the rules must be followed and violation will result in death. With her cool mind, extreme observation and in-depth understanding of the rules, she saw through traps time and time again, avoided death, and relied on common sense and logic to survive until the end.
From the study room to the killing apartment, and then to the bloody battle arena with hundreds of people, she went from passive survival to awakening the ability to manifest rules and turning rules into weapons; on the way, she met Lin Mo, a young man with an eye for data, and the two teamed up to pass the level and tell each other the truth.
She doesn't kill indiscriminately or be a virgin, she only relies on abiding by the rules, breaking the rules, using the rules to crush all dangers, fighting her way out in the infinite dungeon, and finally facing the behind-the-scenes observer in the world of rules.
