A modern agricultural research institute researcher transmigrates into the body of Su Wen, a timid peasant burdened with overwhelming debts. His wife and daughter are constantly bullied by local tyrants. After awakening to his new life, he uses ancient methods to detoxify konjac and creates a unique white frozen tofu, earning his first fortune. He then builds bamboo greenhouses to grow fresh mushrooms out of season and leads the villagers in establishing a cooperative to achieve prosperity together. Just as devastating floods leave countless refugees homeless, Su Wen provides relief through work, reclaiming silt-covered fields and planting taro. He promotes konjac as a filling food to help feed thousands of people. After foiling a conspiracy between unscrupulous merchants and bandits, he donates money to build roads and eventually receives an imperial plaque from the court. Together with the entire village, he establishes a stable and prosperous livelihood, leading everyone toward a life of comfort and abundance.
