Demon Lord's Reincarnation

Nyarlom could no longer tell how long he has been in this forsaken place. Since the moment he entered Ren's soul he had only spoken once, and most of his time was spent fighting different incarnations of Ren.

Despite being at his peak strength he was nothing more than a child in front of these monsters. The strongest mortal soul lives up to its legend. 

'The strongest of every era, the legend that can never be forgotten.' Nyarlom couldn't help but remember that legend as he was getting pounded away by one of the incarnations. After fighting countless incarnations of the Strongest Mortal Soul Nyarlom understood a few things. These guys were practically unbeatable with his level of power. 

'That must be why they say in the legends only beings that can surpass the world can face an incarnation of the Strongest Mortal Soul.' He also understood that no matter what kind of damage he has taken in this soul realm, even if it was his death, he would always be revived a few seconds later. So there was no escaping this place even in death. 

Another thing he noticed was if you stop fighting, the incarnations would mentally torture you until you want to fight again. Their way of mentally torturing their opponents was something, not even he a Primordial Demon would come up with. 

'These guys are supposed to be heroes, right? Why do they seem more demonic than me a true demon?' 

Nyarlom had given up in resisting and assisted the numerous incarnation by doing sparring sessions. Still, it wasn't all bad, even though he could not receive malice in this place, there was something else that fuels him here. Supposedly in this realm, there was something called Origin energy, the base form of all energy, be it the mana that normal creatures use, or the Malice that Primordial Demons use, even other forms of energy such as Spirit Aura, and Sword Will, and many more could be reproduced using Origin Energy. 

So even in here, Nyarlom was growing stronger, he had already surpassed his former peak and was now stronger than before, yet despite the increase in strength, he was still nothing more than a plaything to most of the incarnations. 

In this place, no matter what kind of legendary being you were, aside from the ORIGIN everyone else would feel like a piece of crap if you come to compare yourself with the monsters that reside in this place, were not even deities dare tread. 

...

"This is getting boring, the only thing that seems to be increasing is just your power output, aside from that you're worthless. You have no technique, all you do is wield your power around like a child." The current incarnation facing Nyarlom spoke as he was holding Nyarlom in a stranglehold. The incarnation let go of Nyarlom and sighed. 

"I wasn't even able to use my weapon, after fighting you twice, I see that there's nothing else you have to offer... Have you learned nothing after facing off against all the different incarnations?"

'What the f*ck do you want me to say here?! Do you want me to say that I learned how to get beaten up?!' Nyarlom wanted to scream but had no energy to do so. Even though theoretically speaking it was impossible to get tired in the soul realm, but it wasn't Nyarlom's body that was tired he felt that it was his spirit that was tired. 

"We used so many different techniques, yet you're unable to learn a single one of them?" No longer able to hold it in Nyarlom replied. 

"What the f*ck, do you want me to learn your techniques as I get beaten up?" When the incarnation heard Nyarlom's reply he tilted his head confused. 

"Huh, isn't that how you learn techniques, you learn them by experiencing them?" 

'Only you weirdos could do such an unbelievable thing!' Nyarlom cried internally. She couldn't say it out loud and only looked at the incarnation dumbfounded. 'Is that why they kept using different techniques as they face me? They were actually trying to teach me.'

"Why?" 

"Huh, why what?" 

"Why are you trying to train me?" Hearing Nyarlom's question the incarnation looked at him as if he was looking at someone stupid. 

"Isn't the answer obvious? We were training you so that you can grow stronger." 

"Aren't you guys afraid that I will grow stronger than you?" The moment those words left Nyarlom's mouth he immediately regretted it. 

"Pfft, HAHAHAHA!" The incarnation started to laugh heartily, which made Nyarlom frown. 

'Yeah, I know that no matter how much you train me I won't be able to surpass you freaking monsters. Still, that doesn't warrant so much laughing.' As if able to read through Nyarlom's mind the incarnation answered. 

"Do not misunderstand, I'm not laughing because I'm looking down on you. No, in fact, it's the opposite, I'm laughing cause I got too excited. Of course, we aren't afraid that you would grow stronger than us, as a matter of fact, I can speak for most of the incarnations that we welcome you growing stronger than all of us. To fight someone that's more powerful than us, and wants to control our very soul, what a wonderful battle that will be." The incarnation then showed the signature vicious smile that all of the incarnations would show as they get truly excited. 

'As expected these guys are insane. They would even train their enemies just so that they can face a stronger opponent.'

"Alright, since you aren't able to learn it as quickly, I'll teach you a simple technique." The incarnation then summoned a halberd. "Oh wait, I guess I should teach you unarmed techniques first." The incarnation unsummoned his halberd and then took a stance, he then showed a couple of fists and leg techniques. 

"Did you get that?" Still startled Nyarlom replied. 

"Can you show it again, but slower?" 

"Fine." 

After a few hours, Nyarlom finally understood the gist of each strike. 

"I'll tell the others to give you some free time after every fight so you can practice." After telling that the incarnation left. 

After that incident, Nyarlom's routine changed a bit. This time after every fight each incarnation would teach him a basic move from their branch of fighting. Even though it was hard to digest all of the techniques he had learned, Nyarlom had tried his very best. 

Now with the increase in his power as well as the refinement of his techniques, Nyarlom felt like a new being. He no longer wished to devour the malice of others, now all he could think of was how to get stronger. Yet even with the change in his mindset and the increase of his abilities, Nyarlom couldn't beat a single incarnation. 

Still, there was a visible improvement. At the start, Nyarlom couldn't even last one move against the incarnations, yet now depending on who he was facing he could last more than ten moves. Some of the incarnations got too excited and taught Nyarlom some advanced forms. 

Unfortunately for Nyarlom he wasn't powerful nor experienced enough to understand those forms properly. He couldn't practice them, since when he tried to do so, his spirit almost self-destructed. Seeing that Nyarlom wasn't at that level yet, some of the incarnations looked a bit disappointed. 

...

Nyarlom continued his days like this, until one day another spirit arrived in Ren's soul realm. It was a familiar person, it was another Primordial Demon. 

'So it's Hako.' Seeing his fellow Primordial looking around confused, Nyarlom approached him. When Hako spotted Nyarlom his eyes widened in astonishment, he was about to ask where they were, but Nyarlom spoke first. 

"Thanks for backing me up, now we can both experience the abyss together." After Nyarlom said those words Hako saw numerous humans appearing and surrounding them. Hako noticed a lot of familiar faces, especially one face that he could never forget. It was Leonard Tranor, when he saw that man Hako immediately knew what he had gotten himself into. 

"Oh, how fun, another Primordial Demon to play with." 

"Ren should collect them all so that we can have a lot of different sparring partners."

Hearing the excited voices of the incarnations of the strongest mortal soul, Nyarlom sighed as he looked at his kin and saw the face of true despair. It was obvious that Hako wanted to flee. 

"Don't even bother trying to escape. Just accept the fact that you have been captured, the faster you accept this the better." 

"Is there really no way to escape?" 

"What do you think, with not only Leonard Tranor here but all the incarnations of the Strongest Mortal Soul, do you still think we have a chance?" Hako looked at all the smiling faces that were surrounding him, and the answer became pretty obvious. 

"Then should we just give up?" Hako looked at Nyarlom filled with reluctance. 

"You better stop thinking unnecessary things, in this place all you need to think of is how to get strong. If you're stronger who knows maybe someday we can escape." Even though what Nyarlom said seem to have some form of hope in it, but for Hako he felt like those words brought only more hopelessness.
