Chapter 583: Relieving Fatigue I (R-18)

 "Huh, who knew experimenting would be so tiring." Alros muttered to himself. The Demon Lord, while enjoyed doing one of his favorite activities, still get tired from doing it over a long period.

 "At least some of them are finished," Alros merely need to create a single Hybrid for one type. One type means for like one ant species being turned into a hybrid, he did not need to make one of other ant species. It saved both time and energy, as little changes need to be made if the species shared some anatomical figure.

 However, even if the number of Hybrid he needed to create were cut down, there still a lot of them, plus he is working hard to ensure the one he focused on would be A-rank Hybrids.

 So far, he had finished Beetle, Scorpion, Hornet, Mantis, and Ant. That still left Spider, Termite, and different Beetle variants. Oh, he loved doing this, almost as much he loved fucking women, but it still a tiring job.
