Pei Shenyu, the elderly matriarch of the Marquis of Ningyuan Manor, awakens from rebirth at eighty years old, with merely three days left before her entire clan is exiled. In her past life, her eldest legitimate grandson Pei Jingxing was bewitched by Su Man’er, a wandering female healer. To marry her, he publicly rejected his betrothal to Princess Qinghe, enraging the emperor. Three hundred members of the manor were banished to the frontier, and Pei Shenyu froze to death along the way. Reborn, she would no longer show mercy.
Pei Shenyu moves swiftly. She reclaims the industries managed by Pei Jingxing, cuts the main branch’s monthly stipends, and elevates her overlooked illegitimate grandson Pei Jingxuan. She warns Pei Jingxing to stay away from Su Man’er, or he will be struck from the family genealogy. Still obsessed, Pei Jingxing brings Su Man’er into the manor. On the early morning of the 15th day of the twelfth lunar month, Pei Shenyu hurries to the palace, petitioning the emperor to remove her eldest grandson from the clan and name Pei Jingxuan the heir. The imperial edict arrives, expelling Pei Jingxing from the household.
