In the 22nd century, Mu Nansheng, a poison medicine scientist of the Chinese National K Organization, was involved in a car accident while escaping from the organization. Once he traveled to the Kaiyuan Kingdom thousands of years ago, he became Mu Nansheng, the daughter of the second wife of the Mu Mansion, who has the reputation of being the most beautiful woman in Kyoto.
Her fiancé was snatched away, her birth mother died tragically, her grandmother was poisoned, her uncle betrayed her, and she was targeted by the venomous snake of the prince and was trapped in prison.
Mu Nansheng, who only wanted to have a happy marriage and enjoy family harmony, swore an oath in front of her mother's grave that the prince would pay with his blood!
