Lu Yuan travels through time to ancient times and takes his wife to seek refuge with her family in their time of poverty. His father-in-law, mother-in-law, and several brothers-in-law show no contempt for them. They would rather tighten their belts as a family than withhold food from the couple. Touched by this warmth, Lu Yuan resolves to work hard and make a better life for them. Using his ingenuity, he leads his brothers-in-law in making soap and brewing fine wine. Through painstaking effort, he gradually lifts his wife's family out of poverty and guides them toward prosperity. Later, his biological parents arrive hoping to take advantage of his success, but his brothers-in-law firmly turn them away. Once life becomes stable, Lu Yuan returns to his books and studies diligently. Through hard work, he advances through the imperial examinations and ultimately achieves a fulfilling life, with a flourishing family business and a successful official career.
