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 fact that Marico was innocent didn't negate the fact that he had indeed murdered several people even if they weren't exactly innocent. That kind of guilt could be amplified by solitude and break a man's will, no matter how strong.

Zach grew worried about Luke because he knew that the prince had a strong sense of justice. Such people were the most adversely affected by moral dilemmas.

For example, choosing between an old man and a kid wasn't too difficult for a villain with no value for human life. He could instantly make the decision to kill one of them to save the other, or he could kill both of them because it didn't matter to him either way.

But a righteous man who believed in justice would study the situation from every perspective and would end up lost in his struggle to do right by both the old man and the kid. He would try to find a righteous reason for his action in a situation where there was none.
