After realizing that her father, King Rui, had lost his throne due to his concubine Tang Jingrou stealing his luck, she fought back forcefully. Qi Zhiyu used a series of tricks to force the King of Wu to be deposed as the crown prince, and then exposed the Tang family's secret exchange of heirs in public, and overthrew the Weiyuan Hou Mansion. In the end, he helped King Rui regain the Sacred Heart.
