Shen Yan, the former chief criminal profiler, suffered from amnesia due to the mysterious and tragic death of his teammates three years ago, so he secluded himself in the old city and opened an investigation office. A murder case in a secret room of an old man living alone caused him to accidentally trigger the "regular crime domain" - red rules appeared on the walls, and those who violated them would be obliterated. Behind the reverse clock and the strange bronze mirror, there was a shocking conspiracy that spanned three years.
Judgment's vision awakened, and memory fragments revived. He was forced to get involved in the fatal game of "Rule Judgment": cracking the cross-dimensional crime domain, fighting against the fallen and disordered, and tracing the truth about the death of his teammates. From the haunted house in Linhai Lane to the top hair belt of the world's seven major sins, every rule cracking is a game of life and death, and every rule fragment points to the origin of original sin.
"The real murderer is hidden in the realm of crime, and the rules determine life and death." Shen Yan uses reasoning as a blade and rules as a shield to fight his way through the darkness of human nature and alien crises, only to find that he has long been the core chess piece of this balancing game.
