Black String of Fate

"A bloodline, huh? Ah, what a way to make me jealous." Xavier commented as he took a stance against that monstrosity that the heavenly demon had transformed into.

'Bloodline. An unfair advantage possessed by those of a legacy lineage. This is what distinguished nobles from the common people in the first place. It is said that these bloodlines are based on the myths of an otherworld, but many debate this idea as being just propaganda to raise the image of nobles.

Tsk, he has grown too strong. I have to finish this quickly.'

Xavier tapped into his soul and started using Desolation's Requiem. A cold energy began rushing through his body, and he could feel his lifespan decreasing by the second.

Though, he could afford a lot more, given that he's now a Savant.

*WOOSH*

With a blinding speed, Xavier charged ahead, aiming towards the neck of the heavenly demon. It was now close to his full power, any more would require drastic sacrifices.

"Your sword isn't sharp enough, junior."

The heavenly demon muttered as he simply raised his sword and blocked the incoming attack with utter ease. There was an expression of indifference on his face as he looked deep into Xavier's eyes.

He smiled as he saw shock, panic, and desperation in those red, arrogant eyes. It was a look he was all too familiar with.

Xavier jumped back and charged again, this time using his whole weight and drawing out all of his power. That look the heavenly demon gave him, that sight of treating him like a pitiful being, he hated that.

But alas, there was something different about this bloodline user. He became far too powerful with just a bloodline awakening. Xavier had faced plenty of others who used bloodlines, including every single member of the hero's party, but never had anyone come close to this overwhelming boost he was witnessing.

"I know what you're thinking of, Xavier. This is not a simple bloodline that you are born with, one that your world is familiar with. It is a true legacy chosen by the holy flame of our cult every three generations. Only those who are the truest to the teachings of the demonic sect are bestowed this gift.

Your shallow pride can never match this power built brick-by-brick by my forefathers."

The heavenly demon now went on the offensive, and Xavier could not even see him approach. His left arm was cut off by an upward slash that he could do nothing against. Before he could come to his senses, he was kicked away towards the very same mountain that the heavenly demon crashed into.

*BOOOM*

The already big crater got even bigger and the whole mountain crumbled down and fell on Xavier. In mere moments, he was crushed beneath a huge pile of stone. The heavenly demon slowly walked towards the pile, with his sword on his shoulders.

"You're not done, are you?"

"Of course not."

A huge blast of energy erupted from the pile, blowing away the house-sized stones. When the dust cleared, the silhouette of a man with a sword in one arm and the other arm growing back in real-time appeared. All the injuries incurred with the attacks just now were glowing with Force and healing extremely quickly.

"Tsk, how tenacious."

Xavier did not respond to the provocation, but once again dashed into the heavenly demon. He only had one hand, but he quickly adapted to the new weight and balance and attacked with full force once again.

The result, this time, was similar, with him being knocked away, but he managed to move the heavenly demon's sword by a millimeter. He had avoided injuries in this exchange, so his previous ones managed to heal fully and his arm had regenerated.

All this cost him a huge amount of energy, but Xavier's reserves were anything but normal. Never once has he fought needing to conserve energy, he just had that much stamina.

'This fucker is no weaker than an Archon. I can see why someone like the Elemental King was needed to kill this bastard.

I only have one choice… It has to be done.'

Demonic Soul Supernova."

Xavier raised his sword and pointed it towards the heavenly demon. Internally, he started using his soul energy to refine soul energy, preparing his newly realized ultimate attack.

The heavenly demon, who was relaxed up until this point, felt an overwhelming amount of dread from his instincts. He looked towards Xavier, who seemed spaced out and rushed with his full force.

"You're too slow, Xavier!"

'SHIT!'

Xavier could not complete the formation of the Soul Star fast enough and was attacked by the heavenly demon, disrupting his technique.

'Unlike that fake silhouette, his instincts can warn him of such a deadly attack. Damn it, my mastery in this new move isn't high enough. How am I supposed to practice a life-sacrificing move in the first place?!'

Xavier, who was once again tossed around, tried to get back up and try again, but was once again interrupted by the heavenly demon.

"How pathetic, don't tell me you're a one-trick pony."

"...Shut the fuck up."

Xavier got up and abandoned the idea of using the demonic soul supernova. He can't execute it because it took too much time to prepare. Plus, being called a one-trick pony pissed him off.

"You fucking annoying bloodline-dependent bastard, I'LL FUCKING KILL YOU!"

With a newfound vigor stemming from his main source of power, wrath, Xavier rushed to attack again. The heavenly demon noticed that instead of getting tired, he was instead springing out more strength out of pure rage.

"What a talent, just getting angry allows you to be stronger. Unfortunately, such a blade will never touch me.
