The quasi-rank 7 Eternal Snake never stopped. It chased after Noah even when his presence vanished.
The creature wasn't stupid. The underlings in the heroic ranks were almost intelligent beasts, so the leader was even smarter. It could vaguely understand what Noah was trying to do.
That understanding mostly came from its instincts. The leader knew that the world was in danger, and Noah's actions taught it about the solution to that issue.
Still, the quasi-rank 7 Snake was a magical beast. There was a limit to how much it could care about Noah's good intentions. The creature mostly felt anger at the sight of its dying pack.
Anger wasn't the only feeling that spread in its mind. The leader saw how Noah never spent more than a few instants in each region, and the destruction that he could unleash in that short time was worthy of respect.
