The story is set in the future 2069, and all content has nothing to do with the real image or social system.
The story mainly takes place in the bustling streets of S city. In the year 2069, many similar murders occurred in various cities. In each murder case, there were two victims who were married to each other. The deceased had their arms and legs cut off, and they were all tortured during their lifetimes. No suspicious traces were found at the scene and there were no signs of violent intrusion. These murders were determined to be "serial homicides." But the victims of these murders did not know each other, and most of them were members of the upper class. It was initially determined that the murderer's goal was to take revenge on society.
The protagonist Fang Zizhou is a people's policeman in S city with 5 years of service. He was arranged by his superiors to go to the bustling street with his team leader Chen to assist the forensic doctor Gu Yan in handling the "serial murder case". On the night when Fang Zizhou arrived, he received a report from Happy Park in the bustling street. The deceased, Ms. Gu Kexin, was hanged in the Ferris wheel cabin. Due to lack of manpower and pressure from public opinion, Fang Zizhou was assigned to be responsible for the Ferris wheel incident, while Gu Yan continued to be responsible for the serial murder case.
The case that Fang Zizhou was responsible for went very smoothly. Just when the murderer was about to be arrested and finalized, a diary and an identification report caught Fang Zizhou's attention. A past incident was revealed, and a dirty industrial chain was exposed. No one who walks in the dark is innocent.
