The deposed queen Yu Wanyin was given a glass of poisonous wine to die, but when she woke up, she returned to the night when the Yu family was exterminated. In her previous life, she was an abandoned child of the royal family; in this life, she is a ghost returned from hell. With toxicology knowledge and anatomy skills that transcended the times, she personally opened the corpse's mouth and allowed the dead to speak. From the bizarre death methods of small cases in Jiangnan to the court intrigues of major cases in the capital, all those who destroyed her entire family will die in a "reasonable" way. When she once again stood before the emperor and powerful ministers as the "first female widow in the world", she wanted to settle not only family feuds, but also all crimes and punishments under the imperial power. Why does that cold-faced young man who is looking for the truth always want to hold her blood-stained hand?
