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

Jack and Christina, who had already been released from her bounds were helping out as well.

Although, they were all at the very least B rank mages, Zach and his team made quick work out of them. After all, none of the three had a combat power lower than that of an A rank mage. While Christina and Jack were true A rank mages who were about to reach the S rank, Zach with his light saber wasn't too far behind either.

Dispatching the escorts was too easy for the trio.

Just when Christina was about to blast the last of the escorting guards to bits with her overwhelming magic spell, Zach stopped her by grabbing onto her wrist with the intent to pull her back.
