I received a strange text message while working overtime late at night: "Welcome to the strange rules story, please abide by the following rules - otherwise you will become part of the rules." When he discovered that there was a fatal contradiction between the rules, everyone said he was crazy. But the first person who strictly followed the rules was dragged into the wall alive in front of everyone. I realized: these rules are not meant to be followed, but broken. Each rule is a clue left by a dead person, and the writer of rule 13 died seven days ago. In this world where rules are laws, only by seeing through the truth behind the rules can we leave alive.
