Shen Yiheng, a modern young man, travels back to ancient times and takes charge of the dilapidated and impoverished Taoyuan Village. Zhou Ze, a local gentryman, has long exploited the villagers, using moldy grain to pay taxes, buying grain at unfairly low prices, and putting obstacles in their way at every turn. Shen Yiheng improves farming tools, introduces scientific composting methods, establishes a cooperative, and leads the villagers in making tofu and repairing irrigation canals. Using a modern bookkeeping method, he brings every account into order. He gathers complete evidence of Zhou Ze's embezzlement and illegal occupation of land for a poorly constructed embankment. Rather than seeking revenge, he proves his innocence through hard work and evidence. Leading the entire village to work together, he transforms their lives from constant hunger to overflowing granaries, turning a once-despised poor village into a prosperous and peaceful home.
