Prince Li Chengqian, a modern agriculturist whose soul has passed through a desperate situation, has his left foot hanging in the abyss of deposedness and his right hand holding the "Prosperous Agricultural System". No longer competing for the test paper of the emperor's mind, he chose to plow the first acre of experimental fields within the palace walls. When the potatoes are harvested in the East Palace, when the plow pushes away the undercurrent of the court, what he faces is the scrutiny of Li Shimin, the emperor of the ages, the encirclement and suppression of Guanlong's powerful ministers, and the inertia of the wheel of history. This is a journey of becoming a prince with seeds as sword and granary as armor - what he wants to plant is not only the land, but also the future of the entire Tang Dynasty.
