Reincarnation Of The Strongest Spirit Master

The four looked quite ferocious, and William could recognise these spirits from first glance. "This is indeed bad," these spirits were infamous for the big variety of elements they supported. They were all spirits of dark masters, and quite special ones on top of that.

Seeing such four standing outside, gathering up their power and hammering the shield protecting this lair made William sure this was going to be super hard to stop them.

"Don't panic, as long as we are here, they can't do anything," the golden spirit paused, "but alone I can't do anything. I need your help."

"How?" William pointed at himself, "can't you see? I'm in special shape and mode right now."

"I know, but if that fox prepared for you to come and hold his castle, then he must have left something for you to use in such a state," the golden spirit paused, "I believe you can use your techniques right now, right?"

"Yes, I did it before," William felt puzzled, "but I can't see how it can make a difference…"

"Just try and you'll see for yourself," the golden spirit didn't explain, after all this was one of the special things of the spirit world.

William shrugged, didn't know how using his human techniques would be enough to stop four strong and ferocious spirits. Yet he didn't cling much on doubt, and started using his strongest technique ever; the Holy Sword technique.

He flashed a few times, stacked a few attacks, before releasing them. As he moved, he didn't notice the swirling black power that appeared out of nowhere, surrounding him.

It was clearly visible to the golden spirit, and yet the dude never mentioned anything about it. When William was done, he released the attack towards the emptiness around, not at any specific target. And that was when something new happened.

The attack moved like a gigantic bolt of lightning towards the front, yet it didn't live for more than a few blinks of an eye. A black vortex appeared out of nowhere, without any warning, and sucked dry the entire attack.

"This…" before he'd ask about what happened, he couldn't help but shift his eyes towards the golden screen. And there he spotted something new flashing on its surface.

The same bolt appeared, yet it wasn't small, wasn't just one. Weirdly enough, it felt like a rain was coming, a storm was hitting, and everything around the four spirits got blurred by what William could tell it was a bloody hell storm.

The screen could only relay a detailed image of what was happening out there. Yet it lacked lots of stuff that made William unable to tell what was going on out there.

There was no sound, and the images were just viewing the scenes from one direction, from the outside, without the ability to delve through the current storm he created and tell what was going on to the four spirits inside.

"Don't tell me my attack will harm them!!" William couldn't believe that, but as the storm lasted longer than five minutes, he couldn't help but think about this possibility.

"It can, but not from just one hit," the golden spirit seemed to know much more than what he said, "why are you standing like that? Recuperate and recharge your spirit power to launch another attack!"

"Recharge? Come on! I don't need that," William harrumphed, before releasing another wave of his attack. Like before, the attack came at the enemies outside, boosting the storm outside, enlarging it even further.

One hit after another came, but soon William felt something weird. "My spirit power didn't decrease that much, but why do I feel empty?!!"

He wasn't exaggerating. Right now, he was panting, leaning on his knees, supporting his body with his arms, while feeling tired like never before.

"Told you to recuperate," the golden spirit laughed, "this isn't you using spirit power, it was never like this. Don't tell me you thought you released all this using spirit power? Hilarious!"

"If not, then how did I release the attacks then?" William didn't get it, yet the more he tried to speak, the more tired he felt.

"Just rest, you won't do us any good while being half wasted like this," the golden spirit sighed, "damn you humans, you never listen to a word of advice until it's too late."

William didn't argue against this, as the spirit was right. Yet that made him recall something. "I never suffered from any loss in my spirit power before, I thought this is related to the black fox's special world… Yet it seems I was wrong…"

As he sat down and started to train, he couldn't help but have his thoughts drift towards that point. He fought here before and never felt exhausted nor felt like his spirit power was decreasing.

He always thought this was the act of the black fox, but it seemed like this wasn't the case. "It's something related to the spirit world… Don't tell me these folks don't use spirit power!!" This was a wild conclusion, yet he couldn't think of anything else at the moment.

It was another huge discovery for him. If spirits didn't use spirit power, it meant they use another form of power. And that was like opening a brand new door for him.

He wanted to ask about this quite badly, yet he knew he wouldn't get any answer from that golden spirit. And he didn't have much time even to rest and recuperate.

"Hurry up, they are about to get freed from your attacks," the golden spirit suddenly said, disturbing William from training and thinking, "release three attacks and then have ten minutes of rest."

"I'll try my best then," William stood up, feeling much better. Yet after releasing the second attack, he started to feel weak again, and by the third, he felt even a little dizzy.

"F*ck! I can't keep releasing two attacks," after doing this for the fourth time, William couldn't even keep his body standing, and crashed on the ground, while fighting for his breaths.
