In her previous life, Shen Qingci was the legitimate daughter of the prime minister’s household in the Great Yin Dynasty. Gentle and virtuous, she trusted the wrong people and was framed by her half-sister Shen Yurou and her fiancé, Prince Jing. As her entire family was sentenced to execution, she died in the snowy grounds of the Cold Palace, consumed by bitterness. Reborn overnight, she returns to the eve of her fifteenth birthday ceremony and unexpectedly binds herself to the “Healer’s Heart” System. It can unlock medical knowledge from ancient texts, warn her of danger, and let her trade for rare medicinal herbs. More importantly, it can help her uncover the truth behind her parents’ tragic deaths in her previous life. This time, Shen Qingci casts off her weakness. She wields medicine as a blade and the System as a shield, tears apart her scheming half-sister, kicks her scumbag fiancé to the curb, and protects her family. While healing the sick and saving lives, she also meets Xiao Jinghan, the Marquis of Zhenbei, a man she had never noticed in her previous life. From testing each other’s trust to fighting side by side, she helps him pacify the border and unravel conspiracies, while he shelters and protects her. As the layers of deception are peeled away and the struggle for imperial power grows ever fiercer, Shen Qingci uses the System and her wits not only to change her family’s fate, but also to forge a place of her own in a world in turmoil. In the end, she becomes a legendary physician and joins Xiao Jinghan in protecting their land.
