Agricultural college student Chen Mo guards the rundown farm left by his father, daily pressed for debt by the village bully. His own old well unexpectedly transforms into a spacetime wormhole, connecting to the Qin Xianyang Palace! The emperor through the ages, Qin Shihuang, steps across the door, a two-thousand-year generation gap colliding with modern agriculture, and the artistic style completely goes off track! A bag of potatoes exchanged for a Qin dynasty gold biscuit, folk-method cement and telescopes make Qin infrastructure take off directly, and Chen Mo casually tosses out a world map, making the First Emperor instantly furious: "There is a world beyond Qin? I want all of it!" Selling antiques, paying off huge debts, opening a modern ecological large farm, and directly bringing Qin into the industrial era, even Fusu steadily sits in the position of crown prince!
