Twelve years ago, abnormal copies invaded reality. When others enter the dungeon, they think about how to memorize every rule and how to survive. However, Lu Chen discovered that the rules first determine identity and then behavior. There are priorities, conflicts and loopholes between the rules.
After a call from Black Rain, he was forced to enter the "Midnight Convenience Store". When everyone was abiding by the employee rules, he took off his work badge and changed himself from an "employee" to a "customer". For the first time, he allowed the rules to open up a way for him to survive. He also received the extra reward of "effective use of the rules" from the dungeon for the first time.
