A down-and-out young man accidentally travels back to ancient times and is unexpectedly transformed into a city lord. From then on, relying on his wisdom and hard work, he gradually develops and expands the small city step by step. He turns the tide to save the city lord's mansion, which was on the verge of bankruptcy; he actively implements policies to increase the employment rate of the common people; he outwits and contends with wealthy and powerful gentry to maintain order in the city. In the end, he successfully stabilized the situation, won universal praise, and became a highly respected and good city lord.
