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 energy brimming inside him just a moment ago vanished as soon as Zach showed him the truth of the false hopes, he had been holding out in his heart in order to keep the guilt from eating away at him from the inside.

"...protected her...I should have protected her...kept her safe...safe from that pirate...it's all my fa...it's all my fault...I should have kept her safe..." Bruce's mental state almost broke down at the cold reality as he began to mutter words of regret underneath his breath. He was so consumed by guilt and remorse for not being able to save his sister that he didn't even understand his current condition.

Zach forcefully gave him a sedative and stationed two guards outside his room to keep a watch on him. Bruce needed to calm down. In his current state he was not only a danger to himself but also to those around him. He could be easily manipulated by the enemies in his vulnerable mind state.
