The protagonist awakens the "death rehearsal" ability and can see the death of others and himself. He discovered that he could "reject death" - when the rules locked him, he could transfer death to the rules themselves through "instructions". From then on, he became the "death immune" in the rules world. Everyone was afraid of him, and the rules were also afraid of him.
He entered the dungeon not to escape for his life, but to hunt the rules. For every rule he hunts, he gets a "rule fragment". If he collects a hundred fragments, he can send all players home.
