After cultivating immortality for 300 years, Bai Qianxue is struck by divine lightning and sent back to the mortal world, only to discover that just 30 years have passed outside. Her son and daughter-in-law are already dead, leaving behind only their orphaned daughter, Yaya. Concealing her identity, she disguises herself as a beggar woman to secretly protect her granddaughter. Touched by Yaya's kindness and resilience, she decides to pass on her cultivation powers. With her grandmother's secret assistance, Yaya starts by hunting and selling wild game, defeats village bullies and unscrupulous merchants, establishes a mountain produce company, cultivates rare medicinal herbs, and leads the villagers to prosperity. Eventually, the grandmother and granddaughter reunite, and Bai Qianxue passes down all her extraordinary cultivation powers and beast-taming techniques.
