Zach was a sci-fi game enthusiast who unintentionally crossed over to a magical isekai. Fortunately, he had access to the previous game system and could fight the magic-savvy aborigines with high-tech weapons.
“Magic? No, I have the lightsaber. ”
Unlike what he expected, the system presented him with a different way of leveling up. He had to get some kind of special energy from the pretty girls' bodies on this planet so that he could unlock his weapons.
"What the hell happened? Is my sperm capable of upgrading girls? Can my blood cause those girls to burst out instantly?"
This was incredible.
The succubi were a hated race in the magical isekai because they oversucked male sperm and killed men, but not Zach.
Surprisingly, the majority of the special energy that Zach required was distributed in succubi.
He appeared to be having a fantastic journey.

Release That Succubus

Zach wanted to train these people into a cohesive and complete force that could take on the best forces in the world. He couldn't have them become passive in the face of mages who constituted the greater part of the world's elite forces but were weak to the smallest of his guns. He needed to show them that the mages were not to be feared. They weren't as outstanding as they had believed in the past.

Unfortunately, the belief had been ingrained in their thinking since birth as they were born in slavery and needed to deify something or someone to continue moving forward. To common folk, magic was no less than a miracle.

Therefore, he needed a magic tutor who was not only good at his job but also loyal and trustworthy enough to steer his people in the direction that Zach wanted.
