Fang Zhengyi promoted sweet potato cultivation in Taoyuan to solve the local food shortage. His political achievements caused a stir in the government and the public, and he was recruited to Beijing and was awarded the title of Imperial Imperial Master. The court officials were afraid of his New Deal ideas and set traps everywhere to obstruct reforms. There is an undercurrent of competition for reserve positions, and hidden dangers on the border come one after another. Fang Zhengyi, who is well versed in people's livelihood, based himself in the capital with the concept of enriching the people through farming, and used ingenuity to resolve every conspiracy. He laughed and scolded the forces of all sides, promoted national policies that benefit the people, and cleaned up the accumulated abuses in the court. The grassroots ruffian Emperor Shi starts his journey again, with power and people's livelihood running parallel, and reversals one after another.
