Soren transmigrates into a fantasy world and becomes a destitute baron buried in debt.
His domain is bankrupt, and green-skinned monsters are running rampant outside.
Luckily, he gets bound to a System that lets him buy Earth products with gold coins.
Even crazier, modern industrial goods undergo magical mutations in this other world!
A Glock pistol that costs twenty silver coins fires an instant "Magic Missile" with a pull of the trigger.
A fragmentation grenade worth thirty silver coins becomes a second-circle "Explosive Fireball" when its pin is pulled.
Even five-cent spicy gluten strips can replenish mana!
To hide where his weapons come from, he tricks a hapless fairy kicked out of the academy into taking the fall as his "chief researcher."
He also trains a cold-blooded half-orc assassin catgirl into a food-guarding house cat who only knows how to beg for treats, using a packet of grilled fish strips.
While other nobles are still exploiting serfs, high-ranking mages are still practicing their incantations, and knights are still laboring to cultivate battle aura,
Soren simply grants land and abolishes taxes, then raises a special forces unit armed to the teeth with modern firearms, crushing every foe with overwhelming firepower.
"Who'd want to work hard to become a slave owner?"
Soren presses his gun to the forehead of an enemy lord.
"My lord, times have changed."
