The capital of the Southern Dynasty fell, and the Ye family of Zhongliang was wiped out. The last descendant of the Tianji Sect, Ye Xuanyun, escaped with her younger brother. In order to save the lives of her siblings, she was forced to enter into a contract marriage with Murong Xiao, the regent general of the Northern Dynasty. She endured and lay dormant, using the ancestral secret seal and the secret technique of the organization as a bargaining chip, dealing with the battles in the harem, the struggle for power in the court, and the war between the north and the south. After going through many fatal situations such as poisoning, frame-up, hunting, and kidnapping of relatives, she gradually uncovered the truth of the treason and injustice. Amidst the hatred of the country and the family and the deep love in the troubled times, she grew from an orphan girl on the run to a generation of strange women who can stabilize the country and protect the common people.
