I Have a Military Shop Tab in Fantasy World Novel

Reincarnated into a fantasy world, a high school FPS enthusiast discovers he lacks the typical isekai advantages. Rather than receiving overpowered magic or legendary beasts, he awakens an unusual ability: a military shop system that grants him access to modern American weaponry. Recognizing that contemporary firearms rival magical power in this new realm, he leverages this unique advantage to establish himself. Where others rely on fireballs, he deploys an M203 grenade launcher with superior destructive capability. While summoned beasts serve as companions, he commands UAVs equipped with thermal optics. As mages split oceans through magic, he possesses nuclear weapons capable of erasing entire cities. In a world where traditional magic dominates, his arsenal of military technology proves exponentially more formidable than any spell, allowing him to surpass even the most overpowered magical abilities through sheer technological superiority.
