Demon Lord's Reincarnation

The Elven Queen was talking to the other elders when she suddenly felt the strongest mortal soul's nearing presence. She started to think if she should go by herself or have an entourage. If she came by herself he might think that they were being rude. 

'Tsk, there's no time to think I just bring whoever is available.' The Elven Queen quickly called the nearby soldiers and elders to come with her. 

...

As their group was gliding through the forest, the Elven Queen could feel a powerful presence approaching. When they were by the entrance of the forest, the Elven Queen as well as the other elves couldn't help but stare at the man just outside the perimeter of the forest. 

The current Elven Queen hasn't actually seen an incarnation of the strongest mortal soul but based on the memories passed down by the former elven queens the person standing at the entrance of the forest wasn't someone the elves can mess with.

Now that she has personally seen him she finally understood what those past Elven Queens meant. That sheer force of his presence was frightening not to mention that immense mana that he's trying to suppress. 

The Elven Queen and the others continued to stare in a dazed state. Despite knowing that the one looking like he was reminiscing was the strongest mortal soul, they couldn't help but be shocked. They had met many humans before but none of them possess such abundant and pure mana. 

"Why don't you guys come out and show your faces, or is hiding like rats the elven way?" When the Elven Queen heard that person's voice her whole body shuddered. She and the elders standing behind her quickly stood before Ren and bowed their heads. 

"I'm sorry if bringing this much has offended you." The Elven Queen and the others didn't dare lift their heads as they waited for Ren to say something. Most of them had seen the accounts in regards to the Strongest Mortal Soul.

All the incarnations of this being had nearly identical personalities and fates. They all loved to battle, it was as if they were born to do just that. No one, not even the first Queen that had met an incarnation of the strongest mortal soul knew why they loved battle so much. Aside from that, all the incarnations have been called the strongest of their generation. As long as they get to reach a certain point in their life, it is all but certain that each incarnation would be someone that could shake the world and beyond. They were natural disasters and at the same time saviors. 

...

"It would seem that you guys know who I am."

"Of course stories of the strongest mortal soul has been passed down for ages. Even as the world resets we have been able to somehow sustain the knowledge of the lost epoch." 

'I see they don't know Ren, but they know of my previous incarnations.'

"Hmm... I see... So who are you?" 

"My apologies for not introducing myself beforehand." The Elven Queen once again bowed her head. 

"Enough of the bowing, it's starting to get irritating." The Elven Queen and the others quickly lifted their heads. 

"My apologies, I am the current Elven Queen Kara." 

"So how were you able to determine who I was so quickly?"

"I could read some traces of the flow of fate, and with the memories of the previous Elven Queens I could somehow understand who you are."

"Read the flow of fate?... That does sound interesting, but that's not what I came here for." 

"If there is anything you need, the whole elven race will try and help." 

"Oh?... If you already know about me, that would mean you also know about my last incarnation correct?" When Kara heard Ren's question she couldn't help but sigh in her heart. She already knew that he would ask her this question but she wasn't expecting it to be this terror-inducing. Kara looked Ren in the eyes as she gathered her resolve. 

"Yes, we knew of your past incarnation." 

"Then you should also know what you guys did back then." 

"I know this might sound like an excuse, but those things were done by traitors. We have already dealt with them."

"So you're telling me the ones who helped my son were already killed by you." When the Elven Queen heard what Ren said, she immediately knew that this incarnation has memories of his past life. Another ancient Elven Queen had met a past incarnation with a similar situation. She had was fortunate enough that the incarnation she met was a more understanding type. The one before her now was a former demon lord who had conquered and massacred thousands. Yet for some reason, there was no anger in Ren's tone. 

"Yes, we had killed them all." 

"Heh, that's too bad I wanted to thank those people for helping my foolish yet loyal son."

"Huh?" All the elves who knew of that incident were dumbfounded to hear what Ren said. What did he mean thanking the traitors, as well as having a loyal son?

'If I remember correctly the son he's talking about was the one that killed him in the end. Why is he calling him a loyal son?' Ren noticed the confused looks the Elves were showing and wryly smiled. 

"You all must think my son was a traitor, of course, you would all think that, who wouldn't? But in my eyes, that son of mine was the most filial of all. He had given me the greatest gift I could have ever wanted. He had granted me the taste of defeat, and more than that he had allowed me to die in battle!" Ren viciously smiled as he remembered those final moments in his last life. 

The dullness and boredom he felt before were all erased by that single battle. He was outwitted by his own son and he was defeated promptly. He had numerous battles, more than he could ever remember but among those battles, the one he would never ever forget was that one battle were he had lost. That battle was even more memorable than the one he had with the ORIGIN. 

When Kara heard what Ren said and as she looked at Ren's smiling face, she couldn't help but gulp dryly. This was indeed the strongest mortal soul, the one who loves battle and in return is loved by battle.

"Well, it doesn't matter, since you have already killed them then that's the end of it. Now onto my real business.. I'm here looking for someone."
