Reborn into the public security system of the 1980s, Chen Qingfeng returns with regrets from his previous life and 40 years of criminal investigation experience! There is no systematic golden finger. It relies entirely on hard-core reasoning and on-site investigation. Starting from the unresolved case of Liu Fengying's rape and murder, it overturns the wrong investigation direction and uncovers the hidden female murderer. Then he faced the two kings of Kanto, a tomb-robbing gang, and a serial murderer, and repeatedly solved strange cases using advanced methods such as luminol tracking and psychological portraits. Conflicts in the workplace, entanglements in family relationships, and chasing murderers across cities. In an era of backward technology, he single-handedly rewrites the fate of unsolved cases, and protects the peace of the world with blood and justice. Each case is thrilling, and the whole process is highly reversible!
