Turning the Tables on a Psychopath

(Light parody + Light System + Light supernatural powers; no saintly protagonist, no brainless decisions, and no wish fulfillment! The male lead is naive and pure-hearted, the supporting cast is balanced in strength, and the villain isn't Ding Zhen.)

Breaking the mold! Usually, a psycho goes on a killing spree. This time, an ordinary person fights back and kills the psycho.

A fresh approach! The whole book uses linear storytelling, with chapters that each have a different theme but remain connected.

On his way home, Chen Xionglong, a math teacher at Senhai Elementary School, happens to spot the strange man he encountered earlier that day: the deranged Zheng Haoxue. As Chen Xionglong struggles against the man's restraints, he accidentally kills him in self-defense. How will Li Xing, the flower shop owner who witnessed everything, help Chen Xionglong? And what kind of ties connect the XIS Special Agent Organization to him?
