It appeared as a tiny ball of light, then expanded to form a massive ball of bright white light. Then it started to emit dazzling rays, ones that travelled fast and seemed to cover the entire world.
In the eyes of the masters standing close to this behemoth, it felt like this ball was a bomb that got detonated. As for the masters standing away, they saw the giant form a ball, one that turned to be a real star, shining rays of light brightly and blinding all of them.
The light lasted for ten minutes straight. During which, no one could see anything, not even while using spirit sense. Only William was the only one able to see and control the attack.
The minutes that passed slowly on everyone, felt quite boring to most, passed quite fast over William, while he developed small beads of sweat over his forehead.
They might have released their spirit power to the Troll, but William had to control everything, guide such a brutal force and lead it to attack without allies.
This wasn't an easy feat, as he had no power to perfectly control this behemoth now. He tried his best to just let the rays evade any area close to the masters standing around, even if he left a buffer zone of a few kilometres, didn't risk attacking it.
It felt terrible, but luckily all he had to do was to try his best to control this behemoth, not fuel it. So even if he got exhausted mentally, his spirit power was still the same at the end.
The moment the attack finished, the entire world started to appear again in the eyes and senses of everyone. And the moment that happened, they all sucked a cold air of breath.
"This… Is this the true strength of that weapon?!!!" Even Fang felt a cold shiver down his spine. The world before was filled to the brim with monsters and dark masters, filled with enemies to the brim. But now the world looked vacant and desolate, as all the enemies in here got killed!
There wasn't even a single speck of dust left behind by them. They vanished as if they never existed here before. If not for the standing tall two gates, with newly gushed-out monsters and dark masters coming out from them, then everyone would doubt the enemies before were real.
William killed everything, but left a few monsters and dark masters around them, stretching for a few kilometres around.
"Kill the remaining enemies," William said the words as if he were a god speaking to his creations, "Push the frontline to cover one hundred kilometres then we'll stop. Let's use anything to defend that area, we need to persist as long as we can!"
They all jolted awake by his words, looked at him, then at the giant Troll that was just shrinking in size as if it was totally innocent about all this.
"What are you waiting for? Attack!" The remaining enemies were already petrified by the scary night of the Troll. The Troll released a scary amount of spirit power in such a deadly attack, one that swept clean all the enemies in a mere ten minutes.
As they felt the true might of that attack, they couldn't even move a muscle. And that made the task of clearing them quite easy for the masters when they started attacking.
Then they moved out, and expanded the area to cross one hundred more kilometres quite fast. They didn't meet a single enemy during their march. The enemies needed time to gather up their forces, arrange their lines, and get over the shock and fear from the scary attack the Troll unleashed.
For hours they didn't come at them, and during this, the masters started to use their techniques to form defensive lines.
They made hills, and lightning holes, and even laid down traps with explosives and corrosive materials. They did everything they could, and William just stood behind, working on building more formations.
He didn't forget to collect materials from the unused formations he laid down before. After five hours, the enemy finally managed to gather up enough forces to come at them.
"Let's do our best," Sloth said to everyone around. Right now, they were scarcely scattered across the entire frontline, having a group of tens of weaker masters on their side to help. This wasn't even enough to be considered enough force to stop the incoming enemies. But they had to safeguard the frontline with everything they got.
As the fight resumed again, William finished a few more formations, then he personally joining the fight. Before starting to move out to expand and barricade the frontline, he made sure to leave clear instructions to the digging team.
"I don't care what you'll do, I need you to dig through all this as fast as you can…"
He knew the digging team lacked enough members to dig a hundred kilometres of areas in a short time, but he made sure to let them work on lines, extending from all the way behind to the frontline.
He didn't ask them to do so just to take a look at the entire underground formation, or to make sure they covered the entire formation with this. He wanted to use these deep holes as lines of defence as well.
William had to find a way to help everyone in defending this area as long as they could. Not to mention he had to think about the floating rocks, and find a way to handle this formation.
He still didn't get what the true nature of the formation was. And he had to find out everything about it as soon as possible and find a way to counter it.
Trying to take the floating rocks away from their places wasn't a problem for him. But he had to make sure doing so wouldn't end up triggering the entire formation, ending up detonating the entire area instead of deactivating the formation.
