Fifteen years ago, Shen Nian's biological mother, Liu Yuehua, coveted the position of Empress and slaughtered all 399 members of the Medicine King's Valley clan. She then impersonated Shen Nian's aunt, entered the palace, and was crowned Empress. Shen Nian, who miraculously survived, mastered extraordinary medical skills. When the Crown Prince was poisoned by a deadly toxin and sought treatment, she flatly refused to treat him because of her deep-seated blood feud. The Empress brought people to intimidate her, and Shen Nian was sentenced to death. Countless commoners gathered at the execution ground to plead for justice on her behalf. Shen Nian displayed the coffins of her clanspeople outside the palace and publicly exposed the Empress's crimes, uncovering the deception behind the blood test used to verify their kinship. After the Crown Prince's evil deeds were confirmed, he was sentenced to death. The Empress was sentenced to execution after the autumn harvest, and Shen Nian finally cleared her entire clan's name and restored their honor.
