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.

"EXACTLY~" Frederick chimed as a huge smile covered half his face.

It was then that Raisman felt that he had fallen into a trap woven by his father.

"You see…the female fire mage that he brought with him was at least a C rank mage. Given that she beat our man, who was a D rank mage, within ten seconds without a single scratch, she might even be closer to jumping into the B rank. So consider this…if his subordinate is either a high C rank mage or a B rank mage in the early reaches, what would be the rank of that dark mage then? Can it be lower than his subordinate?" Frederick explained the reason why he hadn't tried to antagonize Zach.
