When Luo Xiaozhou wakes up, he can’t remember a thing. The doctor says his brain has been damaged by a fever, and his best friend says he’s had a hard life. Only Luo Xiaozhou knows that he seems to understand what cats are saying.
As it turns out, he wasn’t human to begin with, but a cat. A cat that had gained intelligence and, for some unknown reason, possessed a human named “Luo Xiaozhou.”
The rules of this world are simple: when evildoers commit crimes, the Heavenly Dao marks them as Ratmen, and cats can possess Ratmen and become Catmen. But the person Luo Xiaozhou possessed was a well-behaved student who neither smoked nor drank nor styled his hair. There was no way he could be a Ratman.
His very existence is a bug that breaks the rules.
This world is full of dangers for Catmen. Fortunately, he awakens a special ability and encounters others like himself.
To survive, he has no choice but to find a way to join the Catmen organization.
