Bardeelus was happy that he fell in a pool which was full of crocodiles. No one in their right mind would feel the same as him, but in comparison to what they went through this past hour, it was easier to handle a bunch of massive crocodiles instead of an undead army.
Crocodiles were the easiest to kill, because no matter how huge in body size, their hearts were still vulnerable. He was in an environment which he could manipulate, so this was a great treat for him!
The water was refreshing too, it splashed him to the point where he focused greatly. He had killed three crocodiles within the first few seconds after he landed, and continued the massacre without remorse.
"12…13, okay, that's pretty good." He counted, but of course it wouldn't be smart to leave any of these beasts alive, so he continued the slaughter.
