During the Jiaqing period, Ye Wanzhou, the daughter of a widower, was involved in the whirlpool of power due to a bizarre murder case. Relying on her family's autopsy skills and modern forensic science knowledge (can be set as time travel or gifted), and under the Qing Dynasty regulations that "emphasis on oral confessions over evidence", she pioneered the use of silver needle poison testing, bone examination, and fly maggots to estimate the time of death, and repeatedly solved strange cases. From a small town in the south of the Yangtze River to the Ministry of Justice in the capital, from local tyrants to palace secret cases, she teamed up with the cold-faced police chief Shen Jinghong to uncover the truth that has been buried in the dust of history.
