Xie Linyuan exchanged a hundred years of his cultivation for a hundred years of lifespan for his wife, A Ning. After junior sister Chu Jing returned, he established the "Ledger of Returned Lifespan", stripping away A Ning's lifespan and tricking her into drinking a decoction causing infertility. Crafting the Youth-Preserving Pill and lighting the Lifesaving Lamp for Chu Jing, he exhausted A Ning's lifespan. With white hair all over her head, A Ning died on the night of Chu Jing's birthday, failing to return home to see her mother. Checking the ledger, Xie Linyuan discovered a miscalculation of twenty years, realizing he had personally killed his wife with remorse beyond remedy. A Ning's mother exposed the sect's vicious deeds, took her daughter back home, and refused compensation. Years later, the mother and daughter's souls were finally reunited, while Xie Linyuan died in loneliness, never receiving forgiveness until his death.
