In the Dajing Dynasty, the heroine Su Qinghe is the daughter of the executioner of the previous dynasty. She has learned top autopsy skills from her father since she was a child, and is proficient in ancient bone examination, autopsy restoration, and toxicology screening. However, her father was involved in the "Canal Canal Works Murder Case" twenty years ago. She was stigmatized as the daughter of a guilty minister and hid in Yizhuang, the capital, to work as a corpse collector. At the beginning, she was involved in a serial case of missing girls because of a female body that died mysteriously, and was targeted by Yin Huaixu, the minister of Dali Temple. She used her autopsy skills to solve the mystery of "living corpses with no injuries and dead bones without traces", cleared her own suspicions, reached a cooperation with Yin Huaixu, and tracked the serial cases as a non-staff partner, but found that each murder was closely related to her father's unjust case back then.
