I Have an Infinitely Upgradeable Farm

Li Chengen's sister was suffering from leukemia. He dropped out of school and returned home. He borrowed 500,000 yuan in foreign debt and was struggling. Li Chengen was lucky enough to open an unlimited upgrade farm, obtain a first-level farm, and discover a nine-section grass that can treat leukemia, a Tianling flower that can treat cancer, and a nine-petal flower that can treat gastroenteritis. His parents suffer from rheumatoid arthritis, so Li Chengen grows Zhenlingguo, which is more than just that. He contracted land, grew vegetables, raised fish, and raised livestock, becoming a world-class rich man, starting a myth of wealth, and running a huge business empire.
