Three years ago, the widower Shen Zhaoye discovered the secret of the Zhenguo Palace using poor women to protect the nobles from disasters, and then a fire broke out in the Dali Temple room. The government found that she secretly altered the files and committed suicide in fear of crime. Xie Wujiu, the young minister of Dali Temple, personally signed the document closing the case.
Three years later, on a cold night, Shen Zhaoye woke up from an "unnamed female corpse" in Yizhuang, west of the city. She has no heartbeat, no household registration, and incomplete memory. She can only be recognized by her autopsy skills and an ancient cyan lamp. Shen Zhaoye found the gold foil of the birthday of Qin Lingyi, the legitimate daughter of the Zhenguo Palace, from the corpse, and concluded that the deceased was not an ordinary maid, but was killed according to Qin Lingyi's identity, and suffered a death that should have happened for her. As the investigation progresses, she discovers that the deceased's name is Su He, who was Qin Lingyi's personal maid. Qin Lingyi no longer wanted to accept someone else's replacement, so she ordered Su He to steal the soul-testing lamp and rescued Shen Zhaoye from the secret room of the Duke's Mansion, who had been sleeping for three years. After the old case was revealed, Shen Zhaoye woke up from the lamp, had a real heartbeat for the first time, and regained his own name and identity.
