Welcome to the world of weird rules.
[Warning: When you open this file, the ghost radio station will be automatically turned on. Please remember three iron rules: don't answer the question of the person in the mirror, don't count the steps of the stairs, and - always trust your shadow. Violation of any of these conditions will result in immediate invalidation of containment.
Everyone thought Cheng Yu was an unlucky guy who accidentally entered the restricted area, until he casually tore up the S-class files and whispered to the twisted containment objects on the floor: "I will rewrite your rules."
From the absolute silence of the ghost radio station to the reverse collapse of the mirror maze, when thousands of monsters prostrate themselves, people were shocked to realize that he was the only living rule itself that was jointly wanted by extraordinary organizations around the world.
