Night Ranger System
The arrival of the third party and the entrance of the ants was too perfectly timed to be a mere coincidence.
After all, when Ianon gazed into the tunnels before, he noticed the ants squirming within, having no intentions of coming out. So, he judged that they weren't the type to participate in such a fight.
This was his misunderstanding since he had been focused on people all along, having not paid much attention to mutated beasts.
Moreover, with the intentions of separating the two fighting parties, the host to the Night Ranger System had been charging an attack that was enough to knock them out. With that, she planned to transport them to different locations.
That was enough to put an end to this unnecessary fight. But now, the situation had changed for some reason.
