The Secret Case of Qingpei: the Crown Prince of Forensic Medicine and the Cold Recruiting Official

In the middle of the Dajing Dynasty, things were peaceful on the surface, but in reality there were undercurrents: the princelings and the Prince's Party were at odds with each other in the court, secretly competing for military and financial power; local officials colluded with aristocratic families and businessmen, corruption was common, official bank was stolen, poisons were smuggled, and serial murders occurred frequently. Suzhou in the south of the Yangtze River is a prosperous place. It is not only a distribution center for salt, medicinal materials, and silk, but also the focus of competition between various forces. The status of the autopsy industry is extremely low and is regarded as a "cheap industry". The technology is backward and it can only simply judge trauma. The official referral and handling of cases mostly rely on oral confessions and lack of systematic testing methods, which provides convenience for the murderer to take advantage of the loopholes and the masterminds behind the scenes to cover up the truth. Xie Heng was demoted to Suzhou precisely to trace the truth behind his brother's death and the "Jiangnan official silver smuggling + serial murder case" (the core major case) involved. Lin Yan's time travel happened to be the key to solving this series of mysteries.
