In Bianjing in the Northern Song Dynasty, Lin Fu, a boy from a poor family, was tricked by his uncle, so he left home and settled in a slum outside the capital with his elderly mother and frail young sister. With no land, no money, and no shortcuts, Lin Fu started by reclaiming wasteland on the outskirts of the city, plowing in the spring, harvesting in the autumn, and storing in the winter. Others thought that growing grain was low-profit, but he insisted on cultivating it intensively and growing high-yielding grain and rice; while others stuck to the old methods without asking for flexibility, he explored composting and breeding techniques to turn wasteland into fertile farmland. From a few minutes of thin farmland to a hundred-acre farm, from growing his own food to supplying restaurants in the capital, Lin Fu used his sweat to carve out a farming avenue in the bustling city. Despised by the powerful? Conquer with real gains; make things difficult for your peers? Stand firm with fair management. Along the way, he opened up wasteland and expanded the land, built workshops and developed agricultural markets, and eventually became the "King of Fields" respected by everyone in the capital, allowing his family to live a good life with plenty of food and clothing, and building a solid foundation for his own farming family in a city where every inch of land is precious.
