Lin Yu was originally a young man who was considered stupid in the village. An accidental slip and fall allowed him to accidentally obtain a cure for the world and save people hidden in a cave. Relying on this good prescription and his own understanding of medical skills, Lin Yu began to show amazing medical skills, curing the villagers who were suffering from illnesses one after another in the village. From being questioned and ridiculed at first, to gradually winning the trust and respect of the villagers, he not only became the village's miracle doctor, but also led the villagers to use the resources in the mountains to develop medicinal materials planting and other industries, putting the whole village on the road to prosperity and writing a legendary counterattack story from "fool" to miracle doctor.
