The apocalypse arrives, and food and water become more precious than human life. When Li Qing awakens, he finds himself already owing a resource quota. Not only has his home been seized, but the Wasteland Hunting Squad has also sent him outside the city as cannon fodder. In this desperate situation, he discovers a spirit spring in the dry well of his own home. Drinking its water strengthens his body, while pouring it onto barren land makes crops grow. From hunting wild boars and claiming wasteland to recruiting people to grow food and building his own team, Li Qing gradually establishes himself with the help of the spirit spring. But as his farmland continues to expand, the squad leader who profits by sending wasteland hunters to their deaths, unscrupulous merchants hoarding relief grain, and various covetous forces begin targeting him one after another. In this famine-stricken world where no one has enough to eat, whoever controls the food controls the entire Black Wheat City.
