Leonel began to quickly make good on what he had missed out on.
The gems were most likely to be found in demons with spatial affinities. This made them very difficult to catch and lock down, and since they were quite rare, just finding them was a great hassle.
Leonel had no reason to hunt down such demons previously because he didn't know anyone with such a higher spatial affinity that would also be in need of such demon carcasses aside from maybe that genius of Earth, Karolus.
He had been potentially thinking of nailing down some with spatial affinities later on if he had the time remaining, but it hadn't been an absolute top priority until this moment. Now, he would go all out against them. As for their escaping abilities, he wasn't worried.
Leonel began to quickly cut down one after another, quickly racking them up.
