Lu Chuan, a surgeon in the provincial capital in the 21st century, died suddenly after a series of operations. He was reborn in 2003, when he was 26 years old, his father had just fallen ill, and his hometown Qingshiwan Village was on the eve of the "old and new fault". Young people in the village are away from home, while the elderly are staying at home. Traditional herbal medicine experience is about to be exhausted. Rural medical care is almost blank. The old bridge leading to the town is also in disrepair, becoming the most intuitive "disconnect" between the village and the outside world. Lu Chuan relied on his medical skills in his previous life and his understanding of the future market. While treating diseases and saving people and rebuilding rural health stations, he also led the villagers to grow medicine, set up cooperatives, build roads and bridges, and fight against the capital forces who wanted to acquire land and build mines at low prices. The story revolves around "technological faults, intergenerational faults, and urban-rural faults." In the game of rural construction and business war, it tells the story of a man's process of putting a village back together that was about to fall apart.
