Qiu Weiyan, a genius widow from a humble background, became famous in the capital for a "bizarre case of the oiran's corpse". She was also involved in the struggle for the throne between the seventh prince Xie Zhifei and the prince Xie Zhiheng. Xie Zhifei is romantic and passionate, and has a strong interest in Qiu Weiyan's talent and calmness, using love as a net to seduce him step by step; Qiu Weiyan, on the other hand, is calm and self-possessed, and uses his power to investigate the tragedy of his adoptive father's family being exterminated many years ago.
As the investigation deepened, Qiu Weiyan discovered that the murder case was intertwined with the feud between the princes, Jianghu forces, and even the secrets of the palace. She uncovered the bloody truth in autopsy after autopsy, but she also fell into Xie Zhifei's web of love and murder time and time again. Xie Zhifei's "passionate" is sincere and a weapon against everyone. He loves her and uses her to make her struggle repeatedly on the edge of love and hate.
When the truth was revealed that the death of her adoptive father was actually related to Xie Zhifei's biological mother, and when her most beloved master (relative) died to protect her, Qiu Weiyan completely cut off her love. Using herself as a pawn, she set up a shocking Shura battle that spanned the court and the rivers and lakes, and finally brought down the prince, Xie Zhifei and all the black hands behind them. Power changed, blood flowed, and she personally sent her former lover to a dead end. After the dust settled, she refused all the rewards from the new emperor and returned to the original mortuary alone, becoming a heartless and heartless "living dead", imprisoning her heart forever.
