Lin Yan, the modern chief forensic doctor, unfortunately fell into the water while tracking down a suspect, and his soul passed through the body of Shen Qingyan, the second lady of the Ministry of Officials of the Dajing Dynasty. The original owner was cowardly, bullied by his sister-in-law, and fell into a trap full of suspicion. With the professionalism of modern forensic medicine and his dedication to the truth, Lin Yan pretended to have amnesia to investigate secretly, and unexpectedly met Xiao Jingyuan, a young minister from Dali Temple who was an expert in solving cases.
With her unique autopsy perspective and criminal investigation thinking, she has repeatedly cracked strange cases for Xiao Jingyuan - from poison murder puzzles to serial murders, from secret fights in deep houses to plots by powerful traitors in the court. She looks for the real murderer in the clues and keeps justice amidst the light of the sword. Xiao Jingyuan was also attracted by her intelligence, courage, and unique qualities. From initial suspicion to later devoted protection, the two worked together to solve the mystery of the case and expose the conspiracy in the court.
In the deep house, she resolves the jealousy of her eldest sister and the strife in the family; above the court, she helps Xiao Jinyuan fight against the powerful traitor and clarify Yu Yu. In the end, the two went through the test of life and death, and were blessed with the divine will to get married. After their marriage, they still worked together to protect the purity of the capital. There are even more naive people who carry on the tradition and continue their original intention of justice. Lin Yan not only found a good match and a destination in ancient times, but also continued his youth with forensic wisdom, allowing justice to travel through time and space and warm the years.
