Lin Wanwan, a doctor of agriculture, traveled through time and became Lin Xiaowan, a poor girl from Qingzhu Village during the Wanli period of the Ming Dynasty.
The family is poor, the father is sick, the mother is weak, and the eldest brother, a gambler, is in debt, forcing the family to despair.
Fortunately, she still had modern knowledge at hand. She used herbal medicine to alleviate her father's illness, used "irrigation to wash out salt" to improve saline-alkali land, and experimented with growing high-yield corn. She was ridiculed for her whimsical ideas but she worked quietly.
Outsmarting wild boars, selling goods for the first time: sugar-fried chestnuts.
She gradually won the trust of the villagers by offering her summer-preventing medicinal soup at the Dragon Boat Festival and offering irrigation models at the Qiao Qiao Festival. But they didn't expect landlords to covet the land, county government to frame them to seize land, and even droughts and plagues to come one after another.
Lin Xiaowan stepped forward: diverting mountain springs to build water trucks to save crops, formulating prescriptions to fight epidemics to save people, and even opened Baicaotang and built an agricultural and medical cooperative, leading the whole village to grow medicinal materials, process medicinal tea and corn flour, and pave business roads to become rich.
During this period, he and the scholar Xiao Jingchen worked together from the compilation of agricultural books to the plague, and their relationship gradually grew.
She outsmarted the powerful, donated rice seeds and was awarded the title of "Agricultural Medical Female Official". She reformed the family and helped her eldest brother quit gambling and become a craftsman, and her younger sister studied and became a talent.
In the end, the water town in the south of the Yangtze River became a beautiful granary. She and Xiao Jingchen worked together in the countryside to write books and educate people, passing on the name of agriculture and medicine - writing farming legends with modern wisdom, and warming the world with benevolent medicine.
