The immortal Wuyi, who had cultivated for three hundred years, fails to overcome her heavenly tribulation and unexpectedly returns to the mortal world, inhabiting the body of Sang Xia, the true daughter of the Grand Tutor who was abandoned by her top-scholar husband, Su Xiangchen. With insight into good and evil and a clear mind, she sees through all kinds of schemes and conspiracies. Facing the cruelty of her cold-hearted former husband, the hypocritical impostor daughter, and biased elders, she remains composed and steadfast, walking her path with integrity. She meets Shangguan Zhao, a noble young master who loyally protects her, and wins the affection of Yue Rongfang, a loving mother, along with a circle of kindhearted confidants. Guided by compassion, she helps the vulnerable, seeks justice for the wronged, exposes the misdeeds of the powerful, and remains true to her principles by doing good and accumulating virtue. Uninterested in the vanity of wealthy families, she ultimately breaks free from society's constraints and lives a life of freedom and integrity uniquely her own.
