Demon Lord's Reincarnation

Ren looked at the person Lance brought, he was a middle-aged man that had an angry look. He was radiating bloodlust and anger that could even make Ren sweat. Ren then scanned the man using his mana, the middle-aged man had above average mana but it wasn't even enough to scare a knight in training. 

'This is weird why am I feeling something is wrong?' Ren could feel his very soul being shaken. That must mean that even his past incarnations were feeling weird. Yet not one of them was sure what was wrong with the man. Was his rage so great that it could even affect someone like Ren? This made Ren look at Silika and saw her expression remained the same, even Lance didn't look worried. 

"Master, this is the man who had hired that assassin. He's another one of my uncles, Fean Resteti" Lance tossed the angry Fean towards Ren. 

Once he was face to face with the man Ren got even more confused, he actually felt a bit threatened by Fean's glare. 

"Master are you alright?" 

"Ren is everything okay?" 

Lance and Silika got a bit worried about Ren since he hasn't said anything and continued to simply look at the man. Ren who was still thinking what the feeling was about, discarded the thought for the moment. 

'No matter what it is I'll just deal with it when the time comes.' 

"It's nothing," After answering Lance and Silika's question Ren once again focused on the man before him. 

"Why did you want to kill the Kirche family?" Ren asked but Fean didn't answer. Ren then smacked Fean, making his face bleed. "Answer me!" Despite the pain he was feeling Fean remained silent. Ren then continued to slap Fean's face with enough force not to kill him, but still bring him indescribable pain. 

After a few more slaps, Ren heard Fean whispering. 

"The Reschbeauch kingdom must fall..." After whispering that part, Fean then suddenly shouted in a rage. "The Royals of this sh*tty kingdom should all die! Their allies must all die! They took everything from me! They took my son and killed my wife for trying to take him back! The Serbek Kingdom would have been better rulers than this! That fool tried to give information about the spies from Serbek that have infiltrated the Kingdom. It was a good thing he died... Why must we the Restetis follow the rule of a king who treats us as slaves!"

Ren was about to say something to Fean about his incoherent ramblings, but then he felt something was weird. Even Silika and Lance could feel it as well. 

"Alright, I will give you my body, I only wish for the destruction of the Kingdom of Reschbeauch!" Fean was talking to an invisible being. 

...

Silika who was watching the changes happening to Fean's aura felt an ominous presence. This aura was something she felt before, she remembered the final battle she, Leo, and all the others had on that fateful day.  Even though the presence she was feeling was weaker than that time, she was sure that this person was being possessed by the seed of the ORIGIN.

...

Inside Ren's soul, the other incarnations were having a discussion. They all knew that even against a weak portion of the seed of the ORIGIN, Ren wasn't strong enough to face it. Unlike the time when the original materialized his own body using an artifact, the past incarnations needed to possess Ren's current body. Yet they just can't possess Ren's body to face it. As evidenced by Leonard's past possession Ren's body was still too weak for them to use most of their techniques. They needed someone strong enough to face the seed of the ORIGIN but it had to be an incarnation that can use Ren's weak body to win. 

...

Lance who was seeing the change that was happening to his uncle was confused and at the same time, he felt fearful. He backed away unconsciously as he drew his sword. 

...

Fean Resteti who emitted only an above-average level of mana was now emitting something totally different. Ren didn't know what kind of power it was but it felt really ominous. Yet instead of fear, he felt truly excited. Aside from that one time when he first faced Alfred, this was one of the few times he felt like there was no chance for victory. He couldn't help but smile at the thought. 

...

Fean Resteti's whole demeanor changed as he looked at Ren. It was the same as the first incarnation, Fean Resteti was there but at the same time, Ren felt like he wasn't there. Fean then looked at Ren and spoke in a solemn voice. 

"We meet again my rebellious prodigal son." 

"Hmph, I don't know who the f*ck is possessing you right now, but I'm no son of yours," Ren answered while taking a stance.

"It seems like your current incarnation is still as rebellious as the first, and also as disrespectful... I see unfortunately this is where our talk ends, this life form can no longer control the seed and retain its sanity." The thing that possessed Fean no longer spoke, as the aura Fean had started to get more violent. 

"AAAARRRRGHH!" Fean then roared and without any warning attacked Ren. It was at a speed that not even Ren could perceive, he was only able to see the moment Fean's hand was about to reach his face. Ren then gathered his Spirit Aura to envelope his body as tried to dodge the attack but it still nicked him and blew him away. 

Ren who was about to hit the wall of the cave used a wind spell to soften the blow. As he was going to stabilize himself, another attack from the vicious Fean was coming. There was no technique, no ability used, not even a trace of mana or Spirit Aura was felt, but Fean was currently able to beat up Ren so one-sidedly. 

The fight had only started for a few seconds and Ren looked like he was already half dead. Lance was confused as to what was happening. Silika, on the other hand, wanted to help, but Ren already told her to not interfere. Also, she knew that even if she joined in this fight she will be nothing more than a liability. If only Ren would use the scythe but he refused to use it since the opponent was fighting weaponless.
