There is a kind of place in the world called a forbidden area. It's not a copy, it's not a secret realm, it's not a different dimension - it's the remains of reality swallowed up by logic after someone wrote the rules alive. People who enter the restricted area will not disappear. An identical version of you will appear in the real world, quietly going to work, eating, and sleeping for you, without anyone noticing anything unusual. But the real you is trying your best to make mistakes in a set of rules that you don't know the content of. The Rules Bureau is the official body that regulates restricted areas. Externally, they protect ordinary people; internally, they sell customized restricted areas and use unsuspecting people as guinea pigs. Chen Chi has worked in the Archives Office of the Rules Bureau for three years. He is gentle, obedient, never causes trouble, and all his colleagues think he is easy to talk to. But they didn't know - Chen Chi's younger brother died three years ago in a restricted area where the grade had been deliberately tampered with, and the altered appraisal file had been filed by Chen Chi himself. Thought it was a clerical error. Later he discovered that his younger brother was the scapegoat. Chen Chi did not collapse, did not yell, and did not rush to retaliate immediately. He just quietly spent three years holding the fatal handles of the six key figures in his hands one by one. Then he started to move. At the same time, Shen Zhiyu, an ordinary college student who accidentally entered the restricted area, was crawling out of impossible exits again and again in a death game without a rulebook with his eyes that refused to let go of any details. Everyone said she was lucky. Only Chen Chi, when he saw her for the first time, was sure that this person, like his brother, could see the emotions behind the rules.
