Poor display
It was a mess. It took Nero and Wendy ten minutes, at most, to clear out most of the snakes, barely using any aether along the way. In fact, Nero was the only one using aether at all, and Wendy hadn't even done that. Yet if one were to observe their group, it would look like they had just experienced a massive assault by formidable foes. At least a dozen angry bears, or something along those lines.
Nero was genuinely bewildered by the performance. Kolar had given them combat training from a young age. That was a fact. They must have also received survival training. Surely most of them had their abilities much longer than him as well.
So why then had they all panicked so badly, and reacted so poorly?
