When Alex Carter stumbles upon the truth about his security guard uniform—a gateway to a famine-ravaged past—he realizes fortune has knocked. In this starving world, everyday items become treasures beyond measure: a single bottle of mineral water trades for gold, while instant meal packs command the favor of oirans. Armed with knowledge of modern convenience goods, Alex launches a trade empire spanning two realities. Each transaction converts mundane supplies into wealth, each deal compounding his power in this desperate land. What takes others lifetimes to build, he achieves through strategic commerce between worlds. Dominating the wealth rankings in a single year? Child's play. Uniting an entire empire within twenty-four months? Merely routine. In a world where survival itself is currency, Alex Carter becomes unstoppable—one bottled transaction at a time.
