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

The system had previously reminded him that Christina hid a power that he craved when he first met her in the Luther family estate. Therefore he had easily agreed to her marriage proposal.

Now he wanted to find out exactly how special she was and how much of a treasure cove he had tapped into.

After dismissing several notifications, he finally came across something noteworthy.

[….. has been unlocked. It will be available in the Weapons Arsenal from this moment onwards and can be accessed at any time.]

After a series of notifications regarding the unlocking of new weapons, Zach was dumbfounded. He finally knew how much of a gem Christina was for her. She had opened so many doors for her that it was difficult for him to count the boons of his union with her.  He couldn't help but want to kiss her badly but unfortunately she was still out of her senses and probably tired beyond herself.
