At the end of the Ming Dynasty and the beginning of the Qing Dynasty, Shen Yan, a master of modern agriculture in a small fishing village in the south of the Yangtze River, traveled through time due to a laboratory accident and became a poor boy whose parents both died. He only had half an acre of thin farmland and two thatched huts left, and he depended on his ten-year-old sister. At the beginning of the rainy season, the hut leaked and the rice tank bottomed out. The second uncle wanted to seize the land deed on the grounds of "keeping it for him".
