Doomsday Convenience Store: Dumped & $50K in Debt, I Trade Ramen for Gold

Dumped ruthlessly by his girlfriend, drowning in fifty thousand dollars of loan shark debt, and left orphaned after the passing of both his parents, he had hit rock bottom. With no family to rely on, no partner to support him, and crushing debt looming over his head, he was trapped in utter despair, fully convinced his miserable life was completely over with no way out. His only trivial possession was a shabby, broken-down small convenience store that barely scraped by in the modern world. Yet just as he surrendered to hopelessness, an unbelievable miracle happened: his run-down convenience store began traveling back and forth to a brutal zombie apocalypse dimension, opening a mysterious passage between his desperate modern life and the ruined end-times world. The moment the dimension connection opened, hordes of ferocious zombies swarmed toward his store, violently smashing and slamming against the door in a frenzy. Miraculously, an invisible protective barrier shrouded the entire shop. No matter how wildly the zombies attacked, they could never break through or step foot inside, turning his tiny store into an unbreakable safe haven amid the endless zombie hell. In the resource-depleted apocalypse, ordinary daily supplies became priceless treasures. Simple instant ramen and bottled water, worthless in the modern world, instantly turned into the most hard-core hard currency that desperate survivors would fight tooth and nail for. Seizing the once-in-a-lifetime opportunity, he started his apocalypse business with nothing but a humble tricycle. He hauled cart after cart of daily goods across the dimensional barrier, trading common supplies for pure gold from struggling survivors. Wealth accumulated rapidly, and his business kept expanding. He upgraded his worn-out tricycle into a sturdy cargo truck, transported more supplies efficiently, and gradually expanded and reinforced his store into a spacious, solid survival shelter. As time went by, his territory grew larger and safer, evolving into the only reliable, top-tier safe house in the surrounding apocalyptic ruins. Countless beautiful and desperate female survivors, wandering aimlessly in the zombie-infested wasteland, fought eagerly to join his shelter and seek his protection. With ordinary ham sausages, fresh bread, and endless daily supplies that no one else could offer, he built a massive, thriving business empire from scratch, firmly establishing his absolute dominance and rising to the top in the cruel, lawless zombie apocalypse.
