Three years ago, a "rule restructuring" occurred around the world, and the world was eroded by various weird rules that went against common sense. Logician Chen Mo, unable to turn a blind eye to phenomena that violate logic, has become a rare consultant in dealing with "rule-based anomalies". Relying on his deep understanding of the laws of logic, he finds and exploits loopholes in the rules to solve life-threatening abnormal events. From the infinitely falling elevator to the contaminated victim, Chen Mo traveled through the dangerous new world and gradually uncovered the truth behind the strange rules. In this era of collapse of logic, can he use reason to hold the last anchor for mankind?
