Adopted since childhood by the general's Su family, the Miao border girl Su Luoshuang returned from gathering herbs only to witness the entire Su family slaughtered by the emperor and her loved ones brutally killed. Possessing the Miao secret art of controlling a hundred beasts, she led ten thousand beasts to storm the palace, swearing to avenge her clan. In the Hall of Supreme Harmony, the state preceptor fabricated lies to disrupt the situation, attempting to alienate her from her past with the Su family. Calmly seeing through the conspiracy, Su Luoshuang rescued her biological parents who had been imprisoned for eighteen years, settled accounts with all the villains, took on the heavy burden, and guarded the magnificent rivers and mountains that her adoptive father defended with his life.
