Demon Lord's Reincarnation

The Primordial Demons that escape the seal had gathered a few miles away from the cave from where they were sealed. The place they chose was an open grassland where a few powerful monsters resided, but being the so called father of monsters, the Primordial Demons weren't bothered by them. In fact, they were able to control the monsters and make them part of their army. 

"It has been a long time since I've felt such intense malice in the air." One of the Primordial Demons spoke in excitement. He and the other Primordial Demons were taking in the malice surrounding them. 

"It would seem those five were able to succeed in bringing about the start of chaos." The Primordial Demons could feel their strength finally returning to their peak states. 

"But can you guys smell it in the air? Unlike before the pungent smell of pure mana is stronger now, it all over the place. Some of it is actually merging with our malice." Another chimed in while showing a sour face. He even looked like he was going to puke but did not. 

"Hmm, I guess the Tree of Life has grown larger in this era. Still, this malice that has a bit of mana in it is hard to absorb." The other Primordial Demons nodded their heads agreeing to what was said. 

"Well, it has been about two resets already since we were sealed. Of course, that wretched tree would grow, it's the only living thing that could easily survive the reset. I guess if you think about it, being beaten and sealed by Leonard Tranor was good fortune for us. If we were here during the reset we would've died alongside all the others."

When Leonard's name was spoken the some of the Primordial Demons visibly shivered while the others had a look of anger. 

"Feel grateful for that b*stard who defeated us and sealed all of us! I would rather have died than do that." 

"Still you got to admit that guy was too powerful. He even created a seal that could hide us from the reset." 

"What do you expect wasn't he the reincarnation of the Strongest Mortal Soul?" 

"Now that you mention it there was a rumor at the time that he was indeed the reincarnation of the Strongest Mortal Soul. Where those rumors actually real?" 

"If they weren't how can you explain that guy's existence. He was able to kill most of the War Gods of that era, he played around with adult dragons as if they were toys, and he almost made our whole race go extinct. If he wasn't the Strongest Mortal Soul, then who else could be?" 

"Let's just stop talking about the guy. So what do we do now that we're free?" 

"How about we do the same thing we did eons ago, go our separate ways, and spread as much chaos as possible." 

"Wasn't that the reason for our downfall the last time?" 

"Don't you sense it?" 

"Sense what?" 

"The aura of the other races, it would seem after two resets some of the old races have ceased to exist. The only ones capable of facing us in this era are the elves, the winged ones, the dragons, and the deities. Those elves after the first reset would never leave their territory. The winged ones don't really care about what happens below those clouds of theirs. No matter the era the Dragons would never attack first if not provoked, and the Deities have too many restrictions. Isn't this the Golden Era for our comeback?" The Primordial Demon who spoke licked his lips as he got excited imagining the mayhem he would produce. 

"Wait what about the humans and the dwarves? Last time they were the main reason for our fall. Aside from Leonard Tranor, those pesky humans and dwarves dealt a huge blow on us." 

"Look around you, what do you guys see?" 

"Nothing special, just grass and monsters." 

"That's what I mean, if this were back in our era, the sky would've been filled with floating warships of the humans. This grassland would have had a stronghold of the dwarves, equipped with those irritating mana cannons of theirs. Yet from where we came from to our way here we saw nothing. It's probably safe to assume that the humans and the dwarves of this era aren't the same as before. Not to mention they don't have their trump card the Strongest Mortal Soul at their side. If we play our cards right, we could become the rulers of this era." 

"Do you guys agree with what he said?" 

"It does sound exciting to become the rulers instead of simply being their nightmares. We should try doing it, become the rulers of this era." 

"Before we get to do that, we should gather information first. So let's spread out and in five days let's all meet back here to share the information we gathered."All of the Primordial Demons gathered nodded their heads and moved to different directions. 

...

After five days the Primordial Demons returned to the spot they agreed to. Upon arriving they waited for the others to arrive, yet once the day had ended the Primordial Demons were rather shocked by what they saw. 

"We're missing eleven of us."

"Could it be that they actually died?" 

"I don't know but based on what I saw of the races in this era that seems unlikely." 

"Yeah, that's what I think as well." 

"Alright, maybe they found something fun to do so they couldn't come back. So let's just start without them." 

"I'll go first, I found out that the current humans of this era are a joke. They're extremely weak and they have no idea how to use mana like the old humans. Not only that their equipment is worthless. Not to mention having airships, but in this era, the humans still use horses as their source of transportation."

"I also learned something about the humans. Unlike before when they stood united, but in this era, there are numerous human kingdoms that are at war with each other. We can easily take over and make them our slaves." 

"It's not only the humans but the dwarves of this era are also pathetic. Same as the humans the dwarves have broken out into different clans. They can still create relatively powerful weapons but they refuse to leave the mountains." 

"I found out that there is a new race in this era, called the warbeasts or beastmen. They seem to be artificial humans of sorts. I'm guessing in the past era humans created a hybrid with the mix of animal DNA and their own DNA. They are physically superior to humans but that's all there is to them."

"Heh, that's nothing compared to what I discovered. In this era, there is a race called demons. Supposedly these demons are now just mismatches of the original ones that died in the past era. They are nothing like us and based on what I heard they are also nothing like their predecessors. These current demons abhor conflict, and unless it was a last resort they would never use violence. They are pretty strong compared to the current era humans, but since they don't want to fight they're worthless." 

The Primordial Demons continued to share the information they gathered. When they got near the end of their meeting they noticed something. 

"It would seem the rumors about the Temples of the Deities having chosen their respective heroes were true."

"Who cares, if they have chosen heroes or not." 

"No we shouldn't think that way, even though the current humans aren't as strong as before, we must never underestimate their heroes. Those guys are the same class of humans as the ones who protected the seal. If they even have half the power of the Draconic b*stard they will become a threat to us. We need to handle this properly." 

"Alright we'll be careful, but what about the rumor of the human who is supposedly stronger than heroes?"

"Oh right, the guy who even though he has a B rank in the adventurers guild is said to be stronger than all the S rank adventurers combined." 

"Don't worry too much about that guy. Even if he does prove to be stronger than the heroes, he shouldn't be that much stronger at most he should only be somewhat stronger." 

The strongest of the assembled Primordial Demons didn't speak as everyone was sharing their thoughts, but once everyone seems to be done talking he spoke. 

"Even if it turns out that the heroes are weaker than we expected we shouldn't let our guards down. So for now let's separate into two groups. The first group should investigate the heroes of those Temples. The second group should investigate anything to do with the rumored strongest adventurer. We don't need to rush things this time, we will slowly plant the seeds of Malice in everyone's hearts. Once we're strong enough we could finally destroy the tree of life." 

"Yeah, once that tree is gone, we can make all the other races into our playthings. Just imagining myself torturing an ancient dragon makes me tremble in excitement." 

"Without the tree, we could finally enter an era of eternal chaos!"
