Qin Ming wakes up one day to find himself transformed into a young manor lord during the Zhenguan era of the Tang Dynasty. Faced with barren farmland and the challenges of harsh winters, he introduces winter wheat cultivation, greenhouse vegetables, tea roasting, winemaking, and improved farming tools. His innovations quickly transform the once-dormant Qin Family Manor into a thriving estate. He also takes in displaced refugees and gathers talented people from all walks of life, turning a small manor into a new home that everyone dreams of. Li Shimin, the emperor, secretly visits the estate in disguise, initially intending to test Qin Ming, but is repeatedly impressed by his knowledge and ingenuity. Little does Qin Ming know that every seemingly ordinary step he takes is quietly changing the future of the Great Tang and leading it toward a golden age.
