Mei Nianqing, a resentful spirit from the underworld, learns that she is about to be reincarnated as an aristocratic girl who is well clothed and well-fed until she is three years old. After that, she is trafficked, imprisoned and tortured to death. The resentful spirit was furious and decisively chose to run away with the help of mysterious forces. The underworld searched everywhere but could not find it.
Xu Lingjun is a grievance-releasing master in the Underworld's Grievance-Relieving Department. He was once responsible for channeling grievances for Mei Nianqing. Because he empathized with the resentful spirit, Xu Lingjun was attacked by the resentment. The third wife of Duke Dingguo of the Xilu Dynasty was about to give birth, and the underworld made a hasty decision to reincarnate Xu Lingjun as the vengeful spirit. When she grew older, Xu Lingjun was secretly told that her mission in this life was to protect He Cairen from being taken over by the resentful spirit Mei Nianqing, and to help He Cairen become a queen.
Many years later, He Cairen, who had become the Queen, said: "Lingyun, among my sons, is there anyone you like? If my son can't do it, my nephews can do it too."
Many years later, Mei Nianqing, who had become a gangster assassin, tried hard to persuade her: "Lingyun, career is the most important thing. That Madam He is not good at heart. Do you know that Taoshan, where Princess Bailian was suppressed in the past, is the mountain of love. Don't get carried away and indulge in romance."
Xu Lingjun: "But, I want to have both career and love."
Dijun: "Lingyun, do you really still can't remember it at all?"
Purpose: Equality between men and women
