Tang Yu'an's family runs a small grocery store, and after school every day, he helps mind the shop. One afternoon, his parents are out restocking, leaving him alone in the shop, with a neighbor's older brother helping him with homework. **"Boom—"** Suddenly, the grocery store door slams shut on its own. Tang Yu'an gets up to reopen it—only to find the bustling street outside replaced by a collapsed, desolate wasteland. At the same time, a crisp electronic voice rings in his ears: **【Post-Apocalyptic Grocery Store System activated!】** — After dangling the carrot ("Become the top dimensional merchant to return home"), the system goes into hibernation. The wasteland is fraught with dangers: harsh conditions, fierce natives, terrifying mutated creatures. Survival is hard enough, let alone completing missions to level up. The system doesn’t expect its young new host to succeed. Still, due to protective protocols, it enables the "Lucky Wheel" feature—allowing rewards like points, rare items, or skills via draws (though the odds are *very* low). The system drifts off, ready to find a new host upon waking. Instead, it returns to find the two boys thriving, with "Peace Grocery" franchises spread across the apocalyptic world. And— *AAAAH! Why is its inventory EMPTY?!* Where are the precious items and rare skills hoarded over generations of hosts?! Tang "Gacha Luck King" Yu'an: *Can’t help pulling miracles every time. My bad?*
