Demon Lord's Reincarnation

After meeting with the ORIGIN, the original incarnation quickly went into a lotus position and started meditating. Even though his will that had been tempered through countless battles was the strongest among all the incarnations, the original incarnation was still in a chaotic state from the news he just heard. After stabilizing his emotions the original incarnation's state returned to his usual neutral state. 

'So the time has finally come. Will I be able to win this time?... What the heck am I thinking, of course, I'm going to win this time! As the original incarnation of those battle freaks how can I think of defeat even before a battle starts.' 

When that thought crossed the original incarnation's mind he could not help but shake his head as he smiled. 

'I guess it's been eons since I actually fought a good battle, I have already forgotten the thrill it brings me. I have become a bit rusty... Since the time for the final battle is approaching I need to prepare.' The original incarnation suddenly disappeared from his private space. 

...

In the inner parts of the soul realm, the sound of clashing steel and exploding spells could be heard everywhere. If this was happening in the outside world many dimensions and galaxies would've already crumbled from just a few attacks. 

Among the powerful maniacal group of battle junkies stood two weaklings, well weaklings if you compared them to the people within the soul realm, but in the outside world, the two were considered rather powerful. These two were none other than the Primordial Demons that Ren had captured. 

Even now these two Primordial Demons were trying their hardest in training trying their best to keep up with the lunatics inside the soul realm. Yet despite their efforts, they could barely match up with even the weakest incarnation. 

Every single incarnation that was sparring with each other suddenly stopped as they felt an immense pressure fall upon them. When the numerous incarnation of the Strongest Mortal Soul felt that immense pressure all of them could not help themselves as they smiled that vicious smile of theirs. There was only one person that could emit such pressure that even they who were hailed as the strongest people of their era were having difficulties resisting it. 

"My reincarnations, the final battle is coming, and I want you guys to help me warm up a bit." The original incarnation landed on one of the floating islands. When the other incarnations saw him and heard what he said, they all quickly rushed towards him wanting to challenge the strongest of them all. 

"I should be the one to go first." 

"No, it should be me." 

"You two are both wrong, it should be me. If you guys have a problem with that how about we decide who goes first with a fight." 

Chaos erupted between the many incarnations as all of them wanted to fight the strongest incarnation the original who was the base form for all of them. Seeing that a battle that didn't include him was about to ensue the original incarnation spoke to all of his reincarnations. 

"There's no need for you guys to fight each other. All of you come at me at the same time, since only then would it be a bit of a challenge." When the other incarnations heard such arrogant lines they stopped fighting and stared at the original incarnation. 

All of them had extreme pride and arrogance but they knew that the words spoken by the original incarnation were the truth. They all looked at each other and they hesitated. It was at that moment the nine strongest incarnations appeared. 

"Hahaha! Finally, we get to see the original incarnation's true strength. You guys cast away your pride and let's join hands to fight the strongest among us. If you won't join then you'll be missing out from such wonderous battle!"

The one who spoke with so much excitement in their voice was Leonard Tranor, he was already eager to move in and attack but he held himself back, and waited to see what the others plan to do. 

"Since the final battle is nearing this is a good way to practice a bit of cooperation among us incarnations of the Strongest Mortal Soul. Seeing as our fight against the ORIGIN will most probably not be a one on one fight, but all of us against the ORIGIN. So let's practice our teamwork in the heat of real battle!" This time it was Rei Kuraki who spoke, the second strongest incarnation. 

The other stronger incarnations also spoke about cooperating and eventually, everyone agreed to fight against the original incarnation with all of them as one. Once they agreed to fight, the incarnations that were archers and mages all fired their strongest attacks at the original incarnation. 

Seeing the attacks that could easily obliterate a galaxy coming towards him, the original incarnation smiled a vicious smile and summoned a sword. 

"Origin style swordsmanship second form [Star Breaker]!" The original incarnation's sword grew as large as a planet and pierced forward towards the barrage of ultimate attacks. Upon making contact with the sword all of the attacks from the archers and mages were instantly nullified. 

The Primordial Demons who were watching from afar could not even comprehend what was happening. All they understood was that among the monsters in this realm it was obvious that the guy fighting everyone else was the monster among monsters. 

...

After several days of fighting nonstop, the final winner was obvious. In the middle of the numerous fallen stood on man the original incarnation. Even against all of his reincarnations fighting together he still won. Normally the original incarnation would not be surprised by such an outcome since he already knew most of everything the incarnations knew, their techniques, their philosophies, even their deepest darkest secrets. 

The original incarnation had the most experience and the greatest power among his reincarnations. So even though he was a little bit rusty he knew victory was his. Yet to his surprise his absolute victory without a scratch on him that he envisioned did not come to pass.

The original incarnation looked at his body that had a few wounds here and there in a daze and after a while, he started laughing.

'As expected from my reincarnations! They actually grew so much during the battle that they went beyond my own expectations. If they continue growing at this pace, they might actually win against me. Once they perfect their teamwork even I won't be able to do anything. Though one on one we are nothing much in the face of the ORIGIN's true body, but with this, we might actually stand a chance once I join in.' Just thinking about how much stronger they could become excited him. He then looked at his fallen incarnations and spoke in a loud voice. 

"How about it guys, let's start round two!" The moment those words came out of his mouth, all of the fallen incarnations stood up with a smile on their faces. They all quickly took a battle stance and started attacking again.

The Primordial Demons who had witnessed the entire battle from afar had already gone numb from all they had seen.
