Su Qingwan, a modern-day university student, travels through time to Lotus Village in the ancient kingdom of Dayu, where years of famine have devastated the land. She brings with her a huge stockpile of supplies purchased with the compensation money she received after her parents' deaths, along with modern knowledge. Facing a desperate situation in which her parents in her new life are both dead, her younger siblings are starving, and greedy relatives are pressuring her into marriage, she fights back. Under the guise of receiving guidance from a Bodhisattva, she cleverly uses modern technology to break off her engagement and intimidate her wicked relatives, establishing herself as an untouchable fairy-like immortal. Using the supplies stored in her personal space, Su Qingwan provides for her family's needs. With the help of her modern pet dog, which traveled through time with her, she finds water sources and leads the entire village in fighting a devastating drought. By selling chilled jelly, making starch noodles, producing ice, and boiling down brown sugar, she gradually builds her own business empire, leading her family and women workers from nearby villages to prosperity.
