Liu Qingqing, a modern white-collar worker, unexpectedly finds her soul transported into the body of a poor farm girl in ancient times. By chance, she obtains a plant-trading system that allows her to make money with ease. Using her superb tea-making skills, she cleverly fights back against her domineering aunt's attempt to force her into marriage. She then builds a business with innovative foods such as canned goods and pastries. Along the way, she bravely battles mountain bandits, encounters influential benefactors, and reunites with her older brother, who has become a general. Later, she expands into the capital and opens a winery, rising from humble beginnings to become a powerful business magnate who commands respect throughout the region, while her entire family enjoys an increasingly prosperous life.
