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.

"I understand. I will keep that in mind when I talk to him. Can you send someone over to call him over right now? Why wait when we can begin right now?" demanded Zach as if he had some place else to be at this time of the night.

"And don't let him find out that we don't trust him." Clara asked once again as she grew worried that Zach might use forceful means to get the answer out of him.

"Don't worry and call him here. Tell him that I am going to perform a medical check-up on him because you have been worried for his health during this time. He knows that I have some unique medical skills so he wouldn't doubt you or me when I attach this to him and proceed as per the plan." Zach laid out the whole plan in the open for everyone to consider.
