In the thirty-seventh year of the Qianyuan era of the Dayin dynasty, Chen Mo, a modern master's graduate in agriculture, transmigrates into the son of a wealthy merchant in Luzhou. His estate is beset by crises: the bookkeeper absconds with the money, tenant farmers live in poverty, the salt fields are exploited, and powerful factions covet his holdings. Drawing on his knowledge of modern agriculture, he improves farming tools, cultivates superior seeds, and reforms business practices. He achieves bumper harvests and commercial success, standing in stark contrast to the corrupt aristocracy. In the years to come, he is destined to claim the throne amid the chaos and unite the realm under one dynasty.
