In 2028, cracks in the rules tore reality apart, and humans were randomly dragged into strange cages.
Rule 1: Don't answer the knock on the door, even if it's from the person you're closest to.
Rule 2: The dormitory aunt is safe, but never look at her face.
Rule 3: The above rules are not all true.
Lin Mo's sister was swallowed by the rift a year ago, leaving only one last word: "Go to the old dormitory and stay there for seven nights."
In order to find his sister, he took the initiative to enter this hellish world of rules. He awakened his "eye for paradoxes of rules" and saw through the fatal trap behind every rule. He went from the old staff dormitory to the midnight teaching building, and from the last subway to the hospice hospital.
When the butcher knife of the observant church fell, and when the rift swallowed up the entire city, he finally discovered that his sister was not dead, but voluntarily became a container for the origin of the rules.
This time, he will break all the rules and snatch his sister back from hell!
