章 428: Unbelievable Improvement

Whoosh!

Just as the Shadow Tigers were about to make a move on the being that had stopped them from baring their fangs on their initial target, a wave of dark energy appeared out of nowhere, spanning a height over a few meters tall as it engulfed all of the Shadow Tigers in its vicinity one by one.

"Groooaaarrr!!!" Unsurprisingly, those at the forefront of the group were the first ones to be engulfed by the wave of dark energy, leaving nothing behind from these engulfed bodies whatsoever. 

Naturally, a small portion of those at the middle and the back of the group felt a foreboding feeling that all of them would be engulfed by the wave at some point, thinking that the best course of action at this moment was to turn tail and run.
