Despite feeling so much powerful now, especially after the realization he got about his ability, he didn't let himself get intoxicated by that.
He knew he couldn't wipe out the monsters at all, or even last more than a couple of days here.
He had a limited number of forces, a number that kept shrinking by the expanding list of death by each passing minute. On the other hand, his enemies had endless reinforcements coming from the large number of dungeons in the region.
Dreaming about exterminating all the dungeons and killing all monsters was a childish talk. So Aroon put that station on top of everything else, especially since he now had such a means to protect it.
"Let's do it," without any hesitation he controlled the drilling pillar and made it move towards the depth of the city.
Like it crushed monsters and rocks, this pillar crushed buildings and even killed some mechas fighting against monsters.
