Modern youth Chu Feng inherits a grocery store and unexpectedly transmigrates into the perilous Abyss Dungeon, binding the Two Realms Grocery Store System. He must develop Night City within a limited time, or face elimination upon failure. Relying on modern supplies, he solves famines, resists extreme cold waves, and rescues the elven mage Aaliya. Instead of brute force, he uses food to dismantle enemy forces and neutralize the offensive threats of the nobles. Developing commerce, he exports commodities like instant noodles and white sugar to expand influence, integrates mineral resources, and navigates various lordly factions. From a dilapidated abandoned mine stronghold, he transforms Night City into a prosperous divine kingdom with a population of thirty thousand, radiating across multiple layers of the dungeon.
