The world has been invaded by "abnormal rules", and people must abide by incredible rules to survive. The protagonist Shen Yu is "immune" to rules - he can't see any rules, but he is born with the ability to intuitively understand "how to live". His younger brother Shen Bozhou is the "manifestation" of rules - he can see the dense rules covering the world, but he is on the verge of collapse due to being too sensitive. The brothers are each other's eyes and hands and feet, relying on each other for survival in a broken world.
