Wan Ping'an awakens in 1950s Beijing, transmigrated into the body of a malnourished orphan within the infamous Siheyuan courtyard. Facing a future defined by poverty, interpersonal scheming, and an impending great famine, he initially despairs at his lack of advantages. However, his fortunes change instantly when he binds the unique Farming System.

This powerful cheat allows him to cultivate crops and raise livestock with supernatural efficiency, yielding massive harvests from his meager six mu of land. Armed with a novice gift pack containing a perfect gene potion, master-level Baji Fist, elite culinary skills, and a portable storage space, Wan Ping'an transforms from a victim into a powerhouse. No longer intimidated by the courtyard's notorious residents or the harsh era, he resolves to dominate his surroundings, secure endless food supplies, and punish those who previously oppressed him.

As he begins to unlock the system's potential, Wan Ping'an prepares to turn the tide of history, ensuring he never goes hungry while establishing himself as the undisputed king of the courtyard.
