Traveling Through Another World but the Rust War

[Another world] [Behind the scenes (fake)] [No heroine] [The protagonist is a bit inappropriate (multiple meanings)] As a glorious (but not) science student, Morris traveled to a different world of swords and magic. There are no brave monsters in this world, only a bunch of churches fighting each other, but these churches can really shake the gods. However, Morris said that that was the end of the matter, let's eat first. What? ! Only hard, unpleasant brown bread? ! In this case, everyone should stop playing. The pride of mankind, the heavily armored knight who swept through thousands of armies? Say hello to my torrent of steel! An elf demon archer with perfect shots? Eat my cannon fire to cleanse the ground! A giant dragon that shakes the sky? Air formation assault! A fortress that never falls? Start world nuclear peace! Although it is said that once the cannon is fired, gold will be ten thousand taels, but if I fire the cannon, you will lose the gold. (It may be boring to practice typing. The protagonist is Morris, but it is generally from other people's perspectives, and the protagonist's early scenes are not many.)
