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 Zach could answer Christina in kind and apologize to her symbolically on behalf of Luna, a familiar *ding* sound attracted all his focus.

[You have come into contact with a mysterious power. There is a high chance that some new possibilities might open up if you ingest this power.]

Zach cleared his vision as he took care of the notification window that had popped up out of nowhere. If before he was intent on establishing a connection with the Elizabeth family due to Christina's initiative, he was now focused towards the mysterious power that could only be within this girl.

Zach had never received this kind of message before. Even though he had an ability that allowed him to absorb energy from women and get stronger, the system had never given him this kind of notification for any woman he had come across before; not even Luna.
