Caught in a street gang altercation, Lin Yi is suddenly thrust into a post-apocalyptic nightmare. Naked and desperate, he flees through a hospital corridor as an army of undead closes in—until a miraculous power awakens within him. A dimensional shelter materializes under his control, offering sanctuary in an otherworldly refuge where he reigns supreme. As his shelter expands to Level 2, mysterious rewards arrive: enchanted potato seeds and fertile ground waiting to be cultivated. "Where is the plant button?" Lin Yi demands of the system. "Plant it yourself," comes the cryptic reply. What begins as a desperate escape becomes the foundation of an extraordinary new world. In the shadow of humanity's collapse, Lin Yi must master cultivation, defend his dimensional sanctuary, and discover why humble potatoes hold the key to his survival in this decimated realm.
