I Summon Guns and Cannons in Another World

After transmigrating to another world, I unexpectedly awakened an arms System.

Others use swords and magic, while I use pistols, submachine guns, machine guns, land mines, missiles, and atomic bombs!

You have an army of a hundred thousand mages, but I have my artillery positions!

I'm no good at writing blurbs, so come on in and see for yourself.
