In the twenty-third year of Yong'an, Shen Nianqing, the legitimate daughter of the Shen family, dies in a woodshed consumed by resentment. Her half-sister Shen Nianyao and former fiancé Su Yichen conspire to frame her, leaving her family ruined and dead. As the flames engulf her, she swears through bloodied tears that if she gets another life, her enemies will pay for their crimes in blood.
When she opens her eyes, she has returned to her fifteenth birthday, the day of her hairpin ceremony. Her father is still alive, her mother is healthy, and the Shen family remains a respected scholarly clan in the capital. Meanwhile, wolves in the guise of gentle souls are circling them.
In this life, Shen Nianqing keeps her talents hidden and her claws tucked away. At her hairpin ceremony, she deftly foils her half-sister's scheme; in the garden, she outwits her wicked aunt. She advances step by step, tearing away the masks of the hypocrites around her. She cuts off the wrong match and refuses to marry a treacherous wolf, instead befriending the loyal and gathering allies to build an iron wall around her family.
When the conspiracy returns, she is no longer a lamb waiting to be slaughtered. From the grain transport case to court disputes and the dark secrets of the inner household, she navigates a treacherous world, wielding strategy as a blade and ruthlessness as armor. She will not only protect her family, but also drag each of her former enemies into hell.
Murderous intent hides amid finery. The legitimate daughter returns to fight for a way to survive, and to walk a path of revenge that will overturn heaven and earth.
