Imagine discovering the secret to eternal life...through fatherhood. In *Longevity Starts From Having a Daughter in Old Age*, we meet Xu Mu, a sixty-year-old cultivator seemingly trapped in the lowest ranks of Qi cultivation. Facing the twilight of his years and a stalled path to immortality, Xu Mu makes a life-altering decision: he chooses to embrace mortality, find a wife, and start a family. But fate, it seems, has a sense of humor. On the very day his daughter is born, Xu Mu's stagnant cultivation springs back to life! A mysterious system notification heralds a new beginning: "Blessed with a Daughter! Increase your Luck Value by 10 points every day!" This luck, though unable to directly boost his cultivation, holds the key to mastering skills and unlocking hidden potential. Suddenly, Xu Mu's journey shifts. No longer is he merely seeking a peaceful end; he's driven by a renewed purpose. Marriage and parenthood become the unexpected path to longevity, each milestone – a son, a perfect family – bringing him closer to his ultimate goal. But can Xu Mu balance the responsibilities of raising a family with the demands of a revitalized quest for immortality? Dive into this heartwarming and humorous cultivation story, where the greatest power-up of all might just be the love of a family.
