Lin Chang Geng, a modern entrepreneur, is betrayed and loses his life, only to transmigrate to an alternate world suffering through a famine, where he becomes a frail, impoverished 13-year-old farm boy. His family can barely afford three meals a day, and after splitting from the extended family, they endure constant harassment from his aunt. Fortunately, his family genuinely cares for him. After awakening an exchange mall system, he builds up capital by buying and reselling grain, creates his own amber eggs to launch a business, and leads his parents and elder brother toward a better life through honest hard work. He improves their living conditions, brings his sister-in-law back home, and uses his intelligence and perseverance to support their poor little household as their days grow increasingly prosperous.
