Sloth's thought drifted towards Fang, but soon enough he dropped the idea, "if that old monster had such power, he'd have used it already. No, it's not him..." Sloth was very curious to know from where William learnt such technique. But soon enough, his attention got diverted to the swarms of weak enemies who came at his direction.
"Scram!" Sloth wasn't in the mood to play with these weaklings. But for a moment there, he recalled something, "I need to know where you came from, and what are you doing here... So..."
He cracked his knuckles and looked in an evil way towards the incoming masters. William didn't bother about this point, but Sloth felt like he shouldn't neglect that.
As he started to interrogate those masters while killing those who weren't cooperative, William was pushing forward amidst the masters and monsters.
"This technique is the nemesis for those monsters indeed..." After a few more attempts, William could tell his new technique was sweeping monsters like they were nothing.
Monsters were hard to deal with, as they always hid through the ground, attacked and ran away without warning. But now they couldn't hold their advantage against his technique.
For a reason, the areas he attacked with the technique seemed to dig the monsters out of the ground. He couldn't see clearly though the waves of attacks, but he could tell the monsters were drawn to something in his technique, luring them out of their safe spots in the ground.
At some point, he had to check the areas he attacked to make sure his technique didn't cut the earth open or something.
From examining the leftovers of his technique using spirit sense, he found out that most of the masters got killed and never left behind anything worthy. But this was different for monsters.
He didn't need any spirit sense to tell him that his team was surrounded out there, deep into that part of the underground city. Yet trying to see anything through the tons of enemies, debris, and ruined buildings filling the entire city was impossible.
If he had to know the truth and find his team, he had to go there himself and force his way through everything. And that wasn't a problem to him until he reached that edge of that zone.
*Sizzle!*
"Yes, it's a man-made thing then," as he released an attack that touched the edge of this region, it was clear that it was made by masters.
He unleashed many attacks already, and was familiar with what these attacks would cause. But when he got close enough, his last attack landed and a big part of it got stopped by some sort of a hidden barrier.
The shattered black ball pieces didn't expand like usual, instead almost one third of the pieces got stuck at a barrier, one that rose from the ground to the sky.
As there was something able to stop his technique, it told him how strong the arrays implemented there were. But he didn't jump to considering solutions, waited for the second and more devastating part of his technique to kick in.
And as if his technique got insulted and enraged by such a barrier, almost most of the attacks landed at that barrier. In front of him, the thick tongues of lightning and flashes of lights kept piling up and rising in intensity while the fog swirled and rose higher, trying to dominate that barrier with brutal force.
"Get it," William stood from behind as if he was cheering for his technique. But as expected, the technique failed to crush the barrier.
