Sloth thought William was acting weird thanks to the long coma he suffered recently. In fact, he acted out of kindness before, but William mistook his actions.
"This isn't related to that comma," William muttered to himself, while feeling harder the closer they got from the ground, "it's not a spirit power suffocation... It's like a clash of something from outside with something within me... Is it related to that spirit?"
William couldn't help but move his attention towards the spirit he gained lately from here. That monster was bizarre in the first place, and its spirit must have held tons of secrets, rather than the ones he explored already.
But as Sloth was walking normally, he had to keep up. He had no time to investigate what was going on, and so he decided to activate his spirit at once to counter that pressure.
"Using that this early on?!!" Sloth paused when William's fox spirit appeared, "do you want to retreat and let me handle this?"
"It's fine," William said these words calmly, but inside, he felt a tornado brewing inside. The moment he activated his fox spirit, and something tapped into his spirit power, something that was previously suffocatingly pressuring him.
The moment he activated his spirit and gained his spirit body, it felt like all the pressure was gone. Instead of being pressured, he felt like an external power was gushing fast and in copious amounts, heading directly towards his spirit.
He knew it wasn't spirit power, or else it'd affect everyone else, Sloth included. He knew it was something related to the new spirit he gained, and so he started to think about what this would be.
"It's not touching my spirit power at least," he closed his eyes and examined his spirit power, to end up feeling no change in it, "so... What is it?"
Before he'd figure out what initially pressured then supported him, the two arrived at the ground.
His aim was to bypass the encirclement of these masters, and head directly towards the monsters deep inside. He knew the masters wouldn't pose a threat or a challenge to him and Sloth. His main focus was to test his new technique over the monsters and see how things would turn out.
"I'll release it now," when he got close enough to see the monsters up front, William shouted to warn Sloth from coming closer to him, "stay back there, keep them busy."
"You..." Sloth was getting on the edge thanks to William, but before he'd complete his words, William released his attack.
The technique was launched without a weapon, against what Sloth imagined. The first thing William did was to plant the sword to the ground, roll his sleeves up, before forking his fingers in a grasping motion.
"Let there be death," William muttered to the incarnation fast, but Sloth could hear the last words he mumbled before the attack landed.
The moment William unleashed his new technique, a huge ball of darkness appeared. It wasn't a normal one, even if it grew to a twenty metres radius, it still gave Sloth bad vibes.
The ball expanded in one breath to such a size, then stopped. When Sloth looked closer, he could see arcs of lightning dancing across its surface, but for a reason they got engulfed all with the darkness.
He could see sparks of small dots of lights that popped up and died fast across the surface of that ball as well. And before he'd got any clue of what was going to happen, William suddenly lowered both hands down, as if he was carrying this ball with his bare hands, and was about to throw it away.
And it flew, past over the heads of masters, then monsters. The ball travelled fast, crossing a thousand metres in a single breath, before it finally landed on the ground.
*Boom!*
