Transmigration: Farm Girl Spoiled to Madness And Sets up a Small Food Stall in Town

Shen Qingli, a scientist from a future interstellar era where radiation has wiped out almost all plant life, dies from excessive exposure and awakens in the body of a twelve-year-old girl in an ancient agricultural village. She finds herself in the courtyard of the Shen family, witnessing a bitter dispute between her mother, Li Liuye, and her grandmother, Old Madam Yang. The grandmother intends to force the eldest daughter, Shen Qingping, into a marriage exchange with Liu Ergou, a violent and notorious gambler, to secure a bride for her own son, Liu Dagang. Shen Wenxuan, the father and a newly minted scholar, remains passive and complicit, prioritizing his mother’s wishes over his family’s safety. Shen Qingli, having inherited the original host’s memories and a mysterious "Little Yellow Fish System," intervenes physically, displaying supernatural strength that shocks the onlookers. She protects her mother and sister, leading to a confrontation where Shen Wenxuan demands a divorce to rid himself of his "unfilial" wife and daughters. The situation escalates until Li Liuye’s father, Li Dashan, and her brothers arrive from their natal home in Li Village. They forcefully intervene, demanding a separation agreement rather than a divorce, and escort the women back to their family home.

Upon returning to Li Village, Shen Qingli and her family are warmly welcomed by the Li household, a large, boisterous, but kind-hearted family of butchers and farmers. Shen Qingli discovers that her system allows her to scan and collect pollution-free green plants, which she can exchange for "Little Fish Coins" to purchase items from her interstellar past, including food and medicine. Recognizing the value of this ability, she begins scanning wild grasses and medicinal plants, rapidly accumulating wealth. She uses these resources to improve her new family’s livelihood, secretly placing extra eggs in their chicken coop and later purchasing wild chickens that appear as if by magic. Her actions earn her the reputation of a "lucky star" within the village, strengthening her bond with her grandfather, uncles, and cousins. She also begins training her sister in basic martial arts to help them defend themselves, attributing her strength to an encounter with an immortal, a cover story that her family accepts.

The narrative shifts when Doctor Zheng, the village’s benevolent physician and a neighbor to the Li family, is falsely accused of malpractice by a grieving son whose mother died after visiting him. The local constables arrest the doctor, and the village mobilizes to support him. Shen Qingli accompanies her grandfather and uncles to the county court, where she uses her knowledge of toxicology to defend the doctor. She identifies that the deceased woman died from poisoning caused by wood ear mushrooms that had been soaked in water for too long, producing bongkrekic acid, rather than from the doctor’s medication. By proposing a live test with a mouse, she provides irrefutable evidence of the food poisoning, clearing the doctor’s name and exposing the plaintiff’s attempt at extortion. Her logical reasoning and medical knowledge impress the magistrate and the villagers alike.

In the aftermath, Doctor Zheng, deeply grateful, offers to take Shen Qingli and her sister on as apprentices. Shen Qingli accepts, seeing an opportunity to legitimize her knowledge and access to medicinal resources. She suggests reforms to the doctor’s practice, including a tiered pricing system and a barter option for poor patients, which he adopts. The sisters begin their training, helping to organize herbs and learn the trade. Meanwhile, Shen Qingli continues to utilize her system to benefit her family and community, such as using interstellar fishing bait to help the Li cousins catch an abundance of fish, which she generously shares with the entire village. This act further cements her status as a valued member of Li Village. The story concludes with the family enjoying a feast of fish soup, solidifying their new life away from the toxicity of the Shen household, while Shen Qingli looks toward the future with the security of her system and the support of her newfound family.
