One Hundred Thousand Cavalry Took Me to the Throne

Princess Qihuang of the Nanzhao Kingdom concealed her identity due to a dream and transformed into a medical woman, Xiao Qingxue, to detoxify and cure the illness of Prince Pei Ziyan of Dayong, and to help him win the title of crown prince. The two fell in love for a long time and became husband and wife. Pei Ziyan even promised that he would never take a concubine in his life. However, as soon as Pei Ziyan became the crown prince, he put all past promises behind him, and in order to consolidate his position in the court, he asked to marry Yun Xueyao, the daughter of the general of the auxiliary country, as his principal concubine. Xiao Qingxue was demoted as a concubine, and she wanted to make peace with her, but she encountered many difficulties from the Dayong royal family.
