Zeke was just about done with his task. In fact, if they finish all the troops that came for them, the elites and Zeke would have no trouble vanquishing the other fortresses because, not much could stand in their way.
And while Zeke massacred the enemies that remained for him, the elites also did the same. With all of the regular troops killed, all that was left for the elites to deal with were the generals who were already on their [Primal State].
At this time, Zeke explained to Heron that every incoming enemy has been dealt with. This amazed Heron once again who understood what this meant. And that is, his master went and accomplished this all on his own once again.
"You never fail to amaze me master." Heron said.
"I have no idea what you're talking about." He replied, giving her further instructions to help out the elites.
