Bei Yi, a student in the school's Department of Traditional Chinese Medicine, was assassinated due to an emotional entanglement at school and was reborn into Bei Nujin in another time and space.
Bei Nujin, the most unpopular young lady in the Bei Mansion, was married by her father to the Sixth Prince, the most disliked prince in the royal family. Not long after marrying into the royal family, she was assassinated.
The sixth prince, Leng Zirun, had his mother framed by people in the harem. Leng Zirun was not favored at first. Later, he was always ostracized and exiled to the border. Later, due to some incidents, he was forced to take the road of seizing power by force.
