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

After she retreated, the mage had joined up with Kolt and his troops but he was too tired to pursue Zach and the others at his full speed. Even if he had been in his top condition, there was no guarantee that he would have been able to catch up to them since they were travelling on trucks which didn't utilize any magic or physical ability. As such there was a high possibility that the mage would have exhausted his magic before catching up to the trucks. Even if he did manage to reach Zach, he would have been too tired to attack them in order to halt their progress.

Therefore, when his lord asked him to move ahead to stop Zach and the others, he could only tell him the truth regarding his condition which annoyed Prince Kolt as it put his entire plan in jeopardy.

"Then you are of no use to me in your condition. You might as well have died trying to kill that slut who caused this." Prince Kolt yelled at the mage as if it was his fault that he was exhausted.
