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

Before he could lash out at the merchant, the latter spoke up with a crafty smile.

Zach wondered how the bastard was still able to smile after hitting such a weak girl. He couldn't help but think what the bastard had done with his consciousness.

"Although I don't want to sell this girl to you, I might be willing to trade her with you if you want her so badly."

Zach's expression changed instantly, and his eyes became bloodshot. No one had managed to piss him off to that extent in a while.

Zach bared his teeth and answered with a beastly growl akin to that of an awakening disaster of the apocalypse.

The merchant, though apprehensive of the sudden outburst, didn't care as long as he could achieve his goal of bringing down the Smith family's image in the eyes of the public.
