When rules come down, you must obey them.
Violators will die.
The modern city suddenly changes one day. Subways, hospitals, schools, office buildings... There are countless "regular spaces" hidden in the city. Those who step into it will be forced to abide by strange rules, and those who violate it will encounter unspeakable horrors.
College student Jiang Cheng accidentally gets involved in the rules space, but discovers that these rules are not unbreakable - there are loopholes in the rules, and the truth is hidden under the lies.
This is not a problem that can be solved by force. This is a death game of logic and details.
——Live until the rules are completely broken.
