Barrister Xiao Qingxue transformed into Xiao Qihuang, the heir to the Nanzhao empress. The original owner was the down-and-out prince Pei Ziyan, who pretended to be a medical woman. After Pei Ziyan became powerful, he demoted her as a concubine. Xiao Qingxue couldn't stand Pei Ziyan's hypocrisy, so she not only wanted to reconcile with him, but also wanted to take back everything from the original owner. On the day when Nanzhao's cavalry broke through the palace gate, all the soldiers knelt down to greet them, shouting to take the eldest princess back to the court and enthrone her.
