Demon Invasion: From Cold Weapons to Firearms

Dong Guyunjiu transmigrates into a world where demons and monsters have resurged.

Here, demons run rampant, ghosts roam at night, and evil gods lurk in the shadows! There are also ability users who cultivate spiritual energy to awaken their powers!

Fortunately, he activates the Super System and awakens the Weapon ability.

Demonic beasts? He sweeps them away with a blue-flame Gatling gun in his left hand and blasts the ground with a Katyusha in his right.

Ghosts? Ever seen a 999-meter broadsword? I'll let you run 998 meters first.

Evil gods, let me show you the power of an orbital cannon.

P.S. The early story features melee weapons; modern firearms are introduced in the middle and later parts.

I'm a new author, just starting out.

This novel and its characters are entirely fictional. Any resemblance to real people or events is purely coincidental. Do not imitate.
