It's been like this since forever the great black dragon has destroyed countless kingdoms across all of the continents, he had destroyed everything in his path as he devoured and kill every creatured for countless thousand of years.

Humanity had driven into desparation as they still struggle to slay the evil dragon who had already killed millions of civilians every year.

The dragon never cared, he just wanted to ease his boredom for some reason.

Life for his is the survival of the fittest, only the strong one deserves to decide the life and death of countless creatures.

"Humans are boring, even their so called hero wasn't a match compare to my abilities, every moment my powers grew, the humans seems becoming into weak pitiful mammals."

The demonic dragon lost interest in the battles that even those braindead arrogant adventurers dares to challenge him into his domain.

He had gotten tired of life as it was no longer fun, he the greatest and the most evil dragon who ever lived seems so done of his role.

"What if..."

The dragon seems to be contemplating if he should use his greatest spell to erase his existence into the memories of every humans and other creatures across the world.

"Let's see how it goes."

From the moment the dragon made up it's mind he then proceed his long incantation which needed a bigger medium of energy to continue working.

"Now"

The magic circles then began to grew lager and spread into every continent, a spell that needed his life entire life force as a sacrifice.

BOOM!

The center of the magic circle begins to glow and flash an explosive beam into the sky as the runes had already spread around it.

The runes the dragon had created from all the knowledge he accumulated towards his entire existence.

"Ha haha, now for the final part."

As the energy source is now feeding of his body, he finally began his main goal.

The black dragon mark a rune in his body as he uttered another spell.

"Now"

As the power source continue to devour his entire body, before it could even touch his soul, the dragon's mark had glowed into bright purple.

"I did it, as expected of me, nothing is possible. Bwa haha haha!"

The demonic dragon let at a nerve chilling evil laugh as the time seemed to stop and his soul momentarily leave his body.

"It's weird"

As he took a glance at the surroundings, the environment seemed to turned into lush gray. Everything stop moving, including the spell was on pause.

The soul of the demonic dragon then began heading into the human land as he wanted to search for a soul that he would body swapped himself with.

"Well well well"

Searching from every corners of the land, the demonic dragon finally found his perfect target.

He headed to the empire which was also frozen in lush gray colors.

There are many choices to choose from, but his gaze still lingered at the biggest castle where the royal empire family live.

"Look what do we have here."

From his gaze he had seen a spot were a certain person was peacefully training in the most secured location.

"So, this is the person they tried so hard to kept secret with."

The pureblooded dragon slayer.

A being in the prophecy believed to be the one to kill the evil dragon.

For so many thousands of years of waiting after the prophecy, the dragon slayer child had been born as the first child of the emperor and the empress. They kept it a secret for years so that when the crowned prince finally mature he will finally be able to leave a mark on killing the demonic dragon that once terrorize the world.

"Hehe, unfortunately for you, your life is about to change." The demonic dragon laugh mischievously as he had finally spot his target for possession.

The crowned prince was seen to be practicing holding a sold inside a secluded place, the demonic dragon take out the mark he had prepared for the possession and drew a magic circle filled with dark evil demonic energy, gathering themselves into one careful placement, the rune was ready.

"Done, and now for the moment of truth."

The demonic dragon soul was directly sucked inside the small rune and then the small rune having the soul of the demonic dragon then led it's way into the secluded hidden room.

The demonic rune began headed itself itself where the frozen crowned prince whose still holding a sword.

Whiiiiiish!!

The moment the rune attached itself into the crowned prince chest, it also sucked the crowned prince's soul from from his boys and place the dragon's soul inside.

After the rune successful implanted the demonic dragon's soul inside the crowned prince body. It then flew always back to where the dragon's body was located.

Whiiiiiish!!

The rune attached itself back to the evil dragon's body and put the crowned soul inside.

After the process had ended the rune lost all it's powers and began to dissipate, the moment it disappeared, the time which had been frozen begins to play back to normal like nothing happened as the lush gray colored surroundings also returned to it's normal color.

"Where am I..."

The browned prince now on the demonic dragon's body couldn't help himself but to panic as the energy begins to eat his new flesh.

"Ahhhh! It hurts!"

The crowned prince now inside the demonic dragon's body writhed in pain as the energy begins to touch his soul.

He growled himself in pain as the spell to erase the demonic dragon's existence from the memories and minds of all creatures finally activates.

The energy began to seep into his soul, while the crowned prince's dragon flesh had long been dissipate.

"Help! I'm in pain. It's too painful. Nooooooo!"

The prince growled as his soul was finally erased into existence after the the energy absorbed it.

The spells began to distort reality, as every record of the demonic dragon's existence from across every books and monuments began to fade.

The memory of the existence of the demonic dragon had disappear in everyone's minds with the crowned prince soul being destroyed into oblivion.

* * *

Inside the secluded room, the being who had stolen the body of the crowned prince had finally come into it's consciousness.

"What a pity." The person's handsome face was grinning devilishly as finally reincarnated into a new vessel.

He then took a glance at the sword he was barely holding. The sword was a divine holy relic only a dragon slayer could wield.

The sword seems to shake as if it had still recognizing it's new honor.

"The soul might be different, but the body was still recognized as it's master. Bwa haha!" The demonic dragon let out a hollow laugh as it still processing the events unfolding.

The demonic dragon was already dead so what's the use of this sword now. The demonic dragon was still contemplating what to do with the dragon slayer sword in his hand.

"Hmm... So it's a soul bound item." Seeing the holy relic who hadn't contracted with anyone yet the demonic dragon finally made it's mind to try awakening it.
