Demon Lord's Reincarnation

While Ren was running towards the Serbek Kingdom, Willmont the warrior king of Reschbeauch was finishing off another soldier from the Serbek Kingdom. It has been weeks since he went to the Southern border to defend from the supposed full-scale invasion of the Serbek Kingdom. But the moment he arrived until to this day, they had only been some small skirmishes here and there. 

Also every time he decides to return to the capital the enemy forces show signs of attacking in full force. Not only that Willmont also noticed something weird, among the soldiers of the Serbek Kingdom there, seem to be some demons mixed in. 

'Demons... It can't be those cowards that hide in that little kingdom of theirs. Another force? Either the demons are regaining their former pride, or someone is controlling them. Either way, it's obvious what there plan here is. They're trying to make me stay away from the capital. Seeing as there have been no reports coming back, something is definitely happening in the capital. Even if I want to go back and check on the situation, I can't leave because the threat here is real. They're actually using a whole army as bait... So they had me at checkmate since the beginning.'

King Willmont clicked his tongue and sighed as he looked at the direction of the capital. He had no choice but to trust his foolish sons to protect the Kingdom. He couldn't help but shake his head at the thought. 

As he was thinking of countermeasures, King Willmont suddenly felt an oppressive aura approaching him. He turned around and saw someone dragging the bodies of five men with a rope. The person who was dragging the men was a young man with tattered clothes that revealed his toned body. It would seem that he had battled the five he was dragging, but aside from his clothes, there was no indicator of said battle. His body had no visible wounds, not even a bruise could be seen. 

As King Willmont was looking at the intruder, he finally noticed who the five bodies were. It was his most loyal retainers, the ones that guard him at all times. The five most powerful masters under his service.

"Heya, Kingy I heard you're one the most powerful warrior among the humans. I hope you're better than that old man that calls himself the Grand Mage or whatever. Oh, what are you glaring at? These guys, well I decided to play with them a bit since they might get in the way of our fight. Don't worry I won't kill them since we need powerful humans. Oops, I wasn't supposed to say that. Well, it doesn't matter since I'll kill you and these weaklings. So come at me and show me your strength" The youth then taunted the King to attack. 

"I thought that you need powerful humans, then why do you want to kill me?" The King asked while looking around signaling his men to retreat.

"Hmmm?" The youth tilted his head before answering. "Oh, you misunderstood, sorry about that. What I meant was we want strong humans that we can control. You and that old man aren't humans that we can control, right?"

"I see... Then before you kill me can I ask you a question?" 

"Sure, why not." 

"You're saying that you want to enslave humans, am I too assume you aren't human?" 

"Of course, I ain't something lowly like a human. I'm a proud demon!"

"Aren't demons those that want to be friends with all races? Are you perhaps a deviant of sorts?" The moment King Willmont spoke of demons being friendly with other races the youth's facial expression changed. 

"THOSE GUTLESS THINGS AREN'T DEMONS! Friends with other races? Friends with those inferior races? Those races that are greedy hypocrites that kept on suppressing us? HAHAHA, that's the sh*tiest joke I have ever heard! Enough talk time for you to die!"

...

At the same time, King Willmont was about to face the young demon, Ren was finally nearing the capital city of the Serbek Kingdom. 

It took Ren a full day before he reached the Serbek Kingdom. Even though he was filled with rage, he couldn't help but notice the lack of soldiers patrolling the area. No, it wasn't just soldiers, not even animals nor monsters in the surrounding area. 

As Ren continued to run without pause, he finally spotted someone and that person was blocking his path. Ren was about to pass by, but then he felt a very ominous presence coming from the person in front of him. 

Ren stopped running and looked at the man blocking his path. The aura the man was emitting felt similar to something Ren had encountered before. Ren who was confused at first until he finally remembered where he felt that aura before. 

The being that even his powerful incarnations consider a threat. No, it was the only being his incarnations even considered as an enemy. The one true threat to all of his incarnations.

"The ORIGIN." The man that was possessed by the ORIGIN nodded his head. 

"Yes, it is I, my disobedient son." Hearing the response of the person being possessed, Ren became cautious. Ren quickly covered his whole body with Spirit Aura and gathered his mana onto the tips of his fingertips.

"Are you behind this?" 

"Of course not, I do not need to scheme or play these games with you. I know such things don't work on you my son. The most courageous, the most vicious, the strongest, most powerful son I have ever created. Such petty squabbles among these lesser children should've been beneath you. Yet here you stand as always trying to join in. You should know why I'm here more than anyone. I'm here to help out these lesser brothers of yours, a game between my children should always be fair. But the moment you step into the game, the game can no longer be called fair. So as the parent of all of you, I came to make the game a bit more fair for your lesser brothers."

"What the heck are you saying? You keep on yapping on and on about me being your son, but I don't have a parent like you. My only parents are my honorable father Matias, and my loving mother Milly." 

After Ren said that the ORIGIN stopped talking for a moment. After a few minutes passed, the ORIGIN sighed before speaking. 

"Why do you always disobey me?" 

"Huh?" 

"Every time we meet, all you do is disobey me. From the time I created you, to all your subsequent changes. All you have done is disobey me. Even though in every lifetime, you always meet a tragic end. Even though you know full well that coming back to me, will end you suffering. Even knowing all that you continue to disobey me." 

As the ORIGIN continued talking, the mana of the body he possessed started to rise. 

"Always the disobedient child. No matter what form you take, that trait of yours that always tries to defy me makes you the naughtiest child of all. Before I make the game a bit fair, it's time for a little punishment."
