Thirty minutes later...

Muku and Legion exchanged blows for half an hour without either party gaining an advantage.

Muku was naive to think that he could punch it nonstop until it died. He would use his Telekinesis to disorient it while punching it.

Unfortunately the bastard was just too tough. And the more they fought, the more its regeneration ability improved.

At the beginning it would take a few seconds for it to recover. However, now it healed almost instantly. Which made it harder for Muku to weaken it to the point of landing a decisive blow like he wanted to.

In fact, he ended up being the one with the more visible damage as some of Legion's attacks landed on him.

Fortunately for him, his Mithril armour was strong enough to resist the black energy. However, it took began giving in after numerous blows hitting the same spot.

It was almost like the mindless creature actually thought things through before it did them. But that couldn't be the case, right?...

"Fuck this! Screw the expenditure! You're going down!" Muku screamed in frustration then created distance between himself and Legion.

He used most of his remaining mental energy to lock the creature in place. Then...

Grey light began gathering in-between his hands which he was holding out. The more grey light he gathered, the more the Mithril armour he was wearing faded.

The reason for this was, he was turning the Mithril into energy form. It was an ability only his Mithril had and his normal metal couldn't do.

Which was understandable considering how unique Mithril in every way possible.

Anyway, soon enough Muku's body was completely exposed when the thin layer of Mithril was all gone from his body.

It was exposed then that it wasn't actually his body which had grown bigger. His body didn't change form at all. It was still the same size.

It was just encased by an energy avatar which looked like Muku. The being was made out of a combination of his metal energy and mental energy. It was somewhat transparent in appearance but looked exactly like Muku.

And Muku was chilling with his eyes closed in its chest area. The reason why his eyes were closed will be explained later on in detail.

For now let's just say the avatar was now his body and his body was the core.

Anyway, after gathering all the energy, Muku didn't delay any longer. He let the energy blast go.

"Ka.... Me.... Haaaa.... Mee... Nuh, I'm kidding. Die!" Muku shouted out then released an energy blast which was suspiciously similar to Goku's Kamehameha.

But the colour and movements were different so it totally wasn't the Kamehameha.

Anyway, the blast of destructive Mithril energy quickly made its way toward Legion.

A little smirk appear on Muku's tired looking giant face. From his calculations. The energy blast should be enough to kill the completely bound and defenseless Legion.

He couldn't wait to end things then beat the shit out of Raya for being so unreliable. There was no excuse he was willing to take for how late she was in assisting him. Hell, he didn't assist him at all!

Unfortunately, things didn't always go according to plan no matter how air tight the plan is.

After all, he wasn't omniscient, so he couldn't prepare for everything since he didn't know everything.

With that said, just as the energy blast was about to reach the Legion. Something unexpected and quite creepy happened.

The creature's tosso began splitting up in two from the centre... It happened exactly at the spot where the red line passed through.

Muku had been wondering why that was there... Well now he knew why...

The red line signified a horrific-looking vertical mouth with countless teeth inside. The creature literally had nothing but teeth in its torso. There were no internal organs at all.

Well, there was one other thing. And that was a weird black orb about the size of a beast core. However, it didn't give off the aura beast cores gave off at all.

Before Muku could make sense of it. The energy blast reached Legion. However, instead of being blasted into the afterlife. The creature actually absorbed the blast.

All the energy was drawn in by the black orb and completely sucked in until nothing was left.

Just like that, all of Muku's painstakingly created Mithril was gone.

The blow from the realisation was so strong that he lost concentration for a moment. And that broke his Telekinetic hold on Legion.

The creature which was constantly fighting to break free from the start immediately exploded forward with force the moment it was freed.

Countless thick black vines stabbed forward and pierced through Muku's avatar.

It was so quick Muku couldn't escape. Fortunately for him, he still managed to control his real body to dodge the corrosion vines or he would have been done for.

However, getting his avatar destroyed like that caused a huge backlash which made him spit up a mouthful of blood. Not to mention that the avatar feels things, so he felt the pain of being stabbed everywhere then ripped apart.

To say that Muku was disoriented and out of commission was an understatement at this point.

He could barely even keep himself afloat....

Legion quickly took notice of the insect and a little smirk actually appear on its face.

Then it held its large hand below Muku. Then...

Bwah!

It closed it shut with so much force an mini wave formed around the hand.

With that... Muku was dead. Squashed like a mere bug by

At the very least that's what's Legion thought until he opened his hand to see the squashed remains... And they weren't there.

"HAAaaAAaaAAaAAH!" For the first time ever since the snicker at the start. Legion made a sound.

And instead of the roar you'd expect from a creature like him. He screamed like a human... Just that the voice was way louder than anything a human could be. On top of that, the pitch and intensity kept on changing which made the creature even more creepy.

At one point you'd hear a grown man and the next you'd hear a delicate woman. This was because the Tactoa team had members from both genders...

"So noisy..." Raya's voice rang out behind Legion.

However, before the creature could react....

"Die"

BOOOOOOOOOOOOOOOOOOOOOOOOOOM!

Legion was consumed by an explosion made out of black and white energy. Interestingly enough, the explosion created the Yin and Yang sign at the top which Muku completely missed from where he was.

Anyway, to the informed it was obvious that Raya had used a combination of her darkness and light elements to create one ultimate attack.

And it was as destructive as it could be since Legion was hit point blank...

Muku who had been left in the distance by Raya looked on with a tense expression on his face.

He was amazed by Raya's destructive capabilities she rarely showed. But at the same time he couldn't help but wonder if it was enough. After all, Legion was able to tank his strongest attacks to the point of even devouring his strongest move...

He couldn't help but think that it might eat Raya's attack too.

His eyes widened in surprise the moment the explosion cleared up.

Legion was... Completely gone!

Raya's attack had erased the creature out of existence.

Sure it had been so destructive that it rearranged the already ruined battlefield but still... Why did sheake it look so easy?!

Was Raya really that much stronger than him?...

The mere thought of that possibly being true made Muku feel like vomiting.

He might not have shown it much, but he was always proud of being the strongest member of their team... However now if he dared claim such a thing he'd seem like an idiot.

Raya literally one-shotted a creature which would have killed him if she didn't save him...

"So easy. Why were you struggling with that thing anyway?" Raya appeared beside Muku and taunted him.

"What took you so long?" Muku asked calmly. Completely disregarding the taunt.

"Tsk. Not even a thank you for saving your life. Anyway, do you think that the move I used can be randomly used? Let me tell you this... That was my ultimate attack which I haven't perfected yet. It's called Yin and Yang destruction. By the time I'm done with it, it will be stronger than my space energy blasts. For now, not only does it take long to prepare, it also ate like 95% of my mana. But why are you complaining anyway? Everything worked out okay in the end right? I destroyed the thing which needed to be destroyed. So why are you so salty?" Raya explained herself then complained.

She felt that Muku's attitude was too much. How could be so ungrateful when she saved his life and completed the task he failed to at the same time?

"Sigh... I guess you're right. I'm sorry and thank you..." Muku calmed down a bit and realised that he really was being ungrateful...

"Good. I accept your apology. Now let's go. The others are worried about you..." Raya spoke then grabbed Muku.

The duo then disappeared from the area.

.....

At the centre of the explosion. A several kilometres deep hole was left with nothing but soil in sight.

At the very centre there was a little hole which went deeper like something escaped through it...

But Muku and Raya where long gone. Both of them were mostly spent and Legion's aura was gone so they had no reason to stay at that dangerous area which can easily summon R5s over...
