Traveling through desperate situations and being horrified at the execution ground (beginning): Shen Qingli, a modern forensic doctor, opened her eyes and knelt in the execution ground in the torrential rain, wearing a blood-stained prison uniform. The original owner was falsely accused of murdering his wife (who was actually a scumbag) and was about to be executed. The cold light of the executioner's ghost-headed sword was dazzling. At the critical moment, a horse ridden the rain curtain. The regent Xiao Jue held the gold medal and ordered "Save the person under the sword." He needs Shen Qingli to find out the truth behind the mysterious and sudden death of the late emperor (his brother). Shen Qingli seized the only chance of survival, shocked the audience with professional terminology, and requested an autopsy.
Self-proven by autopsy, the edge is revealed (development): Shen Qingli dissected the body of the original owner's "dead husband" in full view of the public (especially under the scrutiny of Xiao Jue). With professional techniques (simple tools but clear thinking), she found key evidence (such as the real cause of death, poison residue, fake injuries), cleared her grievances, and uncovered the real culprit (the powerful pawn who framed her). His calm, precise and almost cold autopsy process shocked Xiao Jue and the officials present, but also attracted criticism from "witch" and "dirty". Xiao Jue overcame all objections and temporarily took her under his wing (the palace/specific agency) on the grounds of "assisting in the investigation".
The palace is established, and cases arise one after another (in-depth): Shen Qingli is in a delicate situation in the palace (disdain from subordinates, doubts from officials). Xiao Jue throws out suspicious cases (such as the mysterious deaths of powerful people and the theft of secret palace medicine) to test his abilities. Shen Qingli relied on her forensic knowledge (on-site investigation, autopsy, trace evidence analysis) to repeatedly solve strange cases, and uncovered clues pointing to a deeper conspiracy (which may be related to the death of the late emperor and the party disputes in the court).
