Jiang Chenxing, who was the chief female forensic doctor of the Ministry of Public Security in her previous life, was killed in revenge by a serial killer. Opening her eyes and going back to 1985, the seventeen-year-old girl was being married off by her family to a widower from a wealthy family in the town who had lost two wives. On the day of the wedding, she found two bones in the cellar, and everyone thought she was doomed. But she drew the autopsy diagram, extracted the evidence chain, and reported the crime overnight without expression. Three days later, the widower confessed and was punished, and the whole village was upset. From then on, a girl who was expelled from her family and escaped from marriage used logic as sharp as a scalpel to break through the business world in the 1980s: detecting fakes, uncovering spies, and fighting fraud. She doesn't do business, she specializes in dealing with those who do business. And the young police officer who came to investigate her didn't know yet - the biggest case in his life was to fall in love with her.
