The modern woman Nangong Qianqian was unexpectedly reborn, and her soul traveled through the fictional world of the Dajing Dynasty, the daughter-in-law of the Lin family, a poor peasant woman in Qingxi County. At that time, her husband's family had only four walls and a young daughter who was waiting to be fed. With her modern agricultural knowledge and business thinking, she started by improving farm tools and planting high-yielding crops, manufacturing and selling specialty foods, and took the lead in establishing a farmers' cooperative. She gradually led the Lin family out of poverty, and even became a famous merchant in Qingxi County. By chance, she met the regent Ye Sheng who was in disguise to investigate the disaster, and was appreciated by him for his "work-for-food" disaster relief strategy. Later, in order to stabilize the trade route and seek support, Nangong Qianqian went to the capital and officially met Ye Sheng.
