Shen Qingci, a doctor of modern forensic toxicology, dressed as the legitimate daughter of the Hou family who was poisoned on her wedding night. She climbed out of the coffin and transformed into a ghost market poison doctor, using modern knowledge of toxicology to track down the murderer. Fiancé Xiao Jue pressed closer, but under the autopsy silver needle, he discovered half a jade pendant hidden in her sleeve - that was the key evidence in the murder case of the Tai Hospital twenty years ago. When the poison was exposed at the Queen Mother's birthday party, and when the court judge pointed out that she was the murderer, Shen Qingci dissected the drug residue in court and used chromatography to restore the truth: "The poisoner is the apprentice you taught yourself." Xiao Jue picked up the jade pendant she dropped in the pool of blood, and held it with her husband The broken jade in the middle merged into one - the inner wall was clearly engraved with: "Guiyou's unjust case, the real culprit is now at the table." Using poison as the blade and the corpse as evidence, this revenge gambles on human life, and it is also the fire of truth that burned three hundred volumes of medical records twenty years ago.
