I'm bombarding the Supernatural World with my firearms - Chapter 439 - 360: "29.32 million!"_4

Arthur got randomly transported to another world. Some people would find that terrifying, but not for him, who was tired of his old life; it was an opportunity.

And, after having bad luck all his life, the tide changed.

It was a world of magic where wizards fought side-by-side with their familiars. Arthur got summoned to be one of these so-called familiars.

He was furious. The thought of becoming a pet was not something he liked. Well, that changed when he saw who his master was.

A hot-woman. And, to make everything better, Arthur was inside the Frostpeak Magic Academy, which only had women students.

“This is heaven. All familiars are beasts, but I'm different. I'm a good-looking man inside a place filled with hot girls.”

When he thought his luck could not get better, he unlocked a system that helped him with everything. Of course, he used the system for a greater good, like getting girls.

Xiao Yu’an was reincarnated into a novel. As a cut-sleeve teen emperor. ​Terrible, so sad. Because of this, Xiao Yu’an does his best to continue living. But! It’s fine if you guys want to fantasize about the male lead, but can you stop trying to climb into his bed?
