RYU: THE HEAVENLY DEMON
Chapter 1 — The Eighth Primordial
A boundless darkness stretched across an endless plane.
There was no sky, no earth, no stars, and no discernible horizon. Nothing existed in this place except an endless expanse of darkness and a silence so profound that it seemed to swallow even the very concept of thought.
And in the middle of it all floated a man.
Ryu.
Untethered by gravity or any other physical law, his body drifted freely through the endless void, seemingly suspended between existence and nonexistence itself.
Before he even opened his eyes, his entire life flashed before them.
No, not just one life.
Two.
Every little detail, every memory, every experience, and every moment that had shaped him played out in his consciousness.
His first life as Kaden.
His first cry as a baby.
His childhood, his struggles, and all the bullshit life had thrown his way. The countless times he had picked himself back up, the days when he had wanted nothing more than to give up, and the moments that had forced him to become the person he eventually was.
Then came his training.
Jiu-jitsu.
Kickboxing.
The hours of practice, the bruises, the exhaustion, and the discipline required to turn his body into something capable of fighting back against the world. The techniques he had learned, the instincts he had developed, and the knowledge he had accumulated over the years.
All of it.
From his very first breath to the final moments of his first life.
Then the memories shifted.
His second life.
His first cry as a baby in a world that would eventually come to know him as Ryu, the Heavenly Demon.
Born into the monstrous clan once known as the Ryuomen Clan.
A clan where strength was everything, talent was worshipped, and weakness was treated as little more than a disease that needed to be eradicated.
It was a place that would have been considered hell by ordinary people.
But Ryu hadn't been born ordinary.
Far from it.
From the moment he entered the world, he had been blessed with a talent so absurd that it almost seemed like a joke played by the heavens themselves.
Anything he so much as dipped a pinky toe into, he excelled at.
Swordsmanship? A monster.
Assassination? A natural.
War strategy? An absolute menace.
His understanding of qi and his ability to manipulate it were so ridiculous that even the clan's most experienced elders struggled to comprehend how someone so young could possess such control.
And those were only the things he had learned.
What truly made him different were the gifts he had inherited from his ancestors.
The primordial traits.
The very same ancient gifts that had made the Ryuomen Clan a name feared throughout Murim for millennia.
They were the foundation of the clan's terrifying reputation, the source of its most monstrous warriors, and the reason entire sects had learned to think twice before provoking its members.
And Ryu had inherited them all.
His grey-silver hair and unusual eyes were only the most visible signs of what lay beneath the surface.
His natural talent had already been unfair from birth.
The primordial gifts simply made the situation worse.
When the clan discovered that the newborn possessed the founding traits of their ancestors in their purest and most terrifying form, everything changed.
He was no longer merely a gifted child.
He was the heir.
From the moment his potential became apparent, Ryu was treated differently from everyone else in that brutal hellhole. He was showered with resources, given access to knowledge that others could only dream of, and afforded a rare kindness that the clan reserved exclusively for those it considered worthy.
Of course, the Ryuomen Clan's definition of kindness was still questionable at best.
Their idea of raising an heir involved training that would have broken ordinary children, expectations that bordered on insanity, and enough pressure to make most people question whether living was worth the trouble.
But Ryu had never been most people.
He adapted.
He learned.
He grew stronger.
And eventually, he became something that the world itself struggled to accommodate.
The memories continued.
The countless battles he had fought.
The armies he had challenged alone.
The enemies who had underestimated him and paid for it with their lives.
Then came the destruction of his home.
The fall of the Ryuomen Clan.
A once-mighty power brought to its knees by overwhelming numbers and the combined forces of a world that had finally decided it could no longer afford to let the clan exist as it once had.
But the clan's destruction had only been the beginning.
Because once the world learned of Ryu's existence, fear began to spread.
One sect became ten.
Ten became a hundred.
Alliances were formed between people who had spent centuries trying to kill one another. Enemies became temporary allies, old grudges were put aside, and even those who had spent their entire lives hiding from the affairs of Murim eventually came out of seclusion.
All because of one man.
Ryu.
The Heavenly Demon.
The world had banded together to destroy him.
And they had spent years trying.
The memories rushed forward, bringing him to his final battle.
The mountain where the snow never stopped falling.
The endless white plains.
The millions of enemies.
The swords piercing his body.
The blood staining the snow crimson.
He remembered every single moment of it.
The dirty tactics.
The sacrifices.
The countless lives thrown away just to create an opening, even if that opening only allowed someone to land a single hit.
He remembered the pain.
The exhaustion.
The sheer desperation in the eyes of men who had come to kill him, only to realize that they might have to die alongside him to accomplish it.
And finally, he remembered standing there until his very last breath.
Refusing to kneel.
Refusing to give them what they wanted.
Refusing to let the world dictate how his story would end.
The memories gradually faded.
The darkness returned to silence.
And then, finally, Ryu opened his eyes.
They were a peculiar shade of grey, tinted with silver, and they gleamed faintly against the endless black surrounding him.
For a few moments, he simply stared into the void.
Then he spoke.
"So I died, huh?"
His voice was quiet, almost indifferent, with a hint of amusement that seemed entirely out of place given the circumstances.
He tilted his head slightly as the memory of his final battle returned to him.
The amount of underhanded tactics those bastards had used was honestly impressive in the most pathetic way possible.
Poison.
Ambushes.
Sacrificial formations.
Techniques specifically designed to exploit his injuries.
And that was before they started throwing their own people into the slaughter just to exhaust his qi.
It had been the most cowardly, desperate battle he had ever had the pleasure of participating in.
And somehow, it was also one of the most entertaining.
A faint smirk appeared on his face.
"Though they still died in the end. Who would've guessed?"
He let out a quiet chuckle.
"All those holier-than-thou, pathetic wastes of resources."
His expression became slightly more thoughtful.
"Though, in reality, they just wanted me dead because I was a threat to everything they had going on."
He shrugged.
"Can't really blame them, I guess."
His smirk widened.
"I still won in the end."
And that was all that mattered.
He had died, sure.
But he had taken their victory away from them, too.
They had wanted him on his knees.
Instead, the entire world had bowed before his corpse.
Honestly, he couldn't have asked for a better ending.
…Well, maybe one with fewer swords sticking out of him.
That part had been rather unpleasant.
Speaking of which—
Ryu's thoughts drifted back to the sensations he had experienced during those final moments.
Pain.
Real, genuine pain.
It was a strange thing to remember, considering how much punishment his body had endured throughout his second life.
He had been stabbed, slashed, burned, poisoned, and subjected to techniques that would have reduced ordinary martial artists to little more than a bloody mess.
Yet he had continued fighting.
His pain tolerance had been absurd.
But during that final battle, when his body had been riddled with weapons and his strength had finally begun to fade, he had experienced something he hadn't felt in a very long time.
The sensation of his body genuinely struggling to keep going.
A memory surfaced.
The burning pain of steel piercing his flesh.
Then, faintly, a series of unfamiliar notifications appeared in the darkness.
[Pain Resistance: Acquisition Successful.]
[Physical Attack Resistance: Acquisition Successful.]
Ryu didn't hear them.
His eyes remained half-open, his attention still focused on the memories of his previous life.
"I was the best."
He spoke as if he were casually reminiscing about an old accomplishment.
"An absolute monster of talent. The world literally had to adapt to my mere birth."
His expression was almost smug.
"And despite all that, I still ended up dying because a bunch of bastards decided that throwing millions of people at me was a reasonable solution."
He paused.
"…Actually, fair enough."
After all, if he had been in their position, he probably would have tried the same thing.
Probably.
Another notification appeared.
[Acquisition of Unique Skill: Absolute Monster.]
The words flickered briefly before disappearing into the darkness.
Ryu remained unaware.
"And yet…"
His smile faded slightly as another memory surfaced.
The sensation of countless swords piercing his body.
The burning heat spreading through his wounds.
The feeling of his blood soaking into the snow beneath his feet.
"And yet, despite all that, I've never felt more than I did when I died in that life."
He could almost feel it again.
The heat.
The pressure.
The pain of steel buried deep within his flesh.
[Heat Resistance: Acquisition Successful.]
Then came the final sensation.
The cold.
Not the ordinary cold of a winter morning, nor the freezing winds he had endured while training in the Ryuomen Clan.
This had been something else entirely.
The cold touch of death itself.
The snow beneath his feet.
The wind brushing against his face.
The slow fading of warmth from a body that had finally reached its limit.
[Cold Resistance: Acquisition Successful.]
[Heat Resistance and Cold Resistance detected.]
[Merging compatible skills…]
[Skill Acquisition Successful: Thermal Fluctuation Resistance.]
Ryu's expression shifted as another thought occurred to him.
"Man, I didn't even get to use those ridiculous looks of mine properly."
He sighed dramatically.
"All that effort, all that talent, and I spent most of my life getting chased by every random dickhead with a weapon in his hands."
He shook his head.
"What a waste."
[Acquisition of Unique Skill: Celestial Beauty Successful.]
If he had heard that notification, he probably would have been insufferable about it.
Then again, he already was.
Ryu leaned back slightly in the endless darkness, seemingly comfortable despite having absolutely nothing beneath him.
"Haa…"
He exhaled.
"If I get reincarnated again, I'm definitely finding myself a companion."
He paused.
"No, wait."
His expression grew serious.
"For all the time I missed out on that part of life, I'll get multiple."
The decision was apparently final.
[Acquisition of Extra Skill: Eros Successful.]
[Acquisition of Extra Skill: Dark Sage Successful.]
The notifications continued to appear.
Then something changed.
A new message emerged, its characters flickering erratically as though the system itself had encountered something it couldn't properly process.
[Abnormal quantity of soul power detected.]
[Searching the user's soul for an accurate desire…]
[ERROR: %#!£#+}{¥{^]
[ERROR: }^#£%<€#]
[Reconfiguring…]
[ERROR: €>>>>%^€]
For the first time, the darkness seemed to tremble.
Something was happening.
Something far beyond the ordinary acquisition of skills.
The system continued to process Ryu's soul, searching through the remnants of two lifetimes, an extraordinary will, and a quantity of soul power that appeared to defy its existing parameters.
Then, another notification appeared.
[Innate Traits: Configuring…]
[Trait Acquired: Eye of the Demon.]
A brief silence followed.
Then—
[Unique Skill Acquired: Limitless.]
[ERROR: €<€<]
The darkness swallowed the remaining notifications.
And finally, a single message appeared.
Clear.
Unmistakable.
[Welcome, Traveler.]
[You have successfully been reborn as the Eighth Primordial.]
Everything went black.
…
"Ugh… fuck. Where am I?"
Ryu's voice echoed through a vast, otherwise silent cave.
He slowly opened his eyes.
Dark stone surrounded him, forming uneven walls that stretched upward into the shadows. Strange formations protruded from the ceiling, and faint traces of energy drifted through the air like invisible currents.
The atmosphere felt heavy.
Not with pressure, exactly, but with something he had never experienced before.
Magicules.
He could feel them.
They were everywhere, flowing through the cave and gathering around him in quantities that were almost absurd.
Before he could investigate further, a calm, feminine voice spoke directly into his mind.
[Dark Sage: Answering, Master. You are currently inside a cave located within the Demon Realm.]
[Your body is emitting magicules at an excessive rate. It is recommended that you leave the cave and gather further information regarding your surroundings.]
Ryu blinked.
"…Ah. Right."
He looked around the silent cave, taking in his surroundings with a surprisingly calm expression.
Well, that explained absolutely nothing.
He had apparently died, been processed by some kind of system, and reincarnated as something called the Eighth Primordial.
And now he was sitting inside a cave in a place called the Demon Realm.
Honestly, he had experienced stranger things.
Probably.
He sat there for a moment, allowing his thoughts to settle before deciding to deal with the most immediate problem.
"Hey, Dark Sage."
[Yes, Master?]
"Why do I feel different?"
He flexed his fingers, studying his hands.
"Physically, I mean. I can feel it. My body's different. Stronger, somehow. And I can sense the amount of… what did you call it? Magicules?"
[Correct, Master.]
"Right. Magicules."
He leaned back slightly, closing his eyes as he focused on the energy circulating within his body.
Even without having anything to compare it against, he could tell there was an absurd amount of it.
It wasn't merely a feeling of being powerful.
It was as though his body had been designed to contain something far beyond the limits of an ordinary creature.
"And I'm guessing this isn't normal?"
[Answering, Master. Your current physical and spiritual constitution is fundamentally different from that of an ordinary demon.]
Ryu raised an eyebrow.
[You are a Primordial Demon, one of the oldest and most powerful categories of spiritual life within this world's known demonic hierarchy.]
He remained silent, allowing the information to sink in.
[After analyzing your current existence, I have determined that you are the Eighth Primordial and the last of your kind to have emerged.]
A brief pause followed.
[Your designation is Grey, the Primordial Demon of Grey.]
Silence.
Ryu stared at the cave wall.
Then he slowly turned his head toward the empty air.
"…Grey?"
[Affirmative, Master.]
He blinked once.
Twice.
"That's it? Grey?"
[That is your current designation.]
Ryu stared into space for another moment before letting out a quiet laugh.
"Well, shit. Could've been worse, I guess."
He wasn't particularly attached to the name, but it wasn't as though he had any immediate plans to argue with the universe over it.
Besides, he had bigger things to worry about.
He leaned forward, resting his elbows on his knees as he began organizing his thoughts.
"Alright. I need information."
[Understood, Master.]
"First, I need to understand what I am, what I can do, and where the hell I am. I still have all my old instincts and knowledge, so replicating my previous fighting style with this body should be easy enough."
He glanced down at his hands again.
The body felt different, but not unfamiliar in the way he had expected. His instincts were still there. His understanding of combat hadn't disappeared, and the experience accumulated across his two lives remained firmly within his mind.
If anything, it felt as though his old knowledge had been placed inside a vessel that was capable of doing far more with it.
That was promising.
Very promising.
"But there's a problem."
His expression grew slightly more serious.
"If I'm already at the top of a food chain that I know absolutely nothing about, then that means there are probably others who occupy a similar position."
He tapped a finger against his knee.
"And if there are seven other Primordials, there's a chance they might be able to sense my existence."
He paused.
"Or find out about me somehow."
[Your assessment is reasonable, Master. However, insufficient information is currently available to determine whether the other Primordials can detect your presence.]
"Yeah, figured."
Ryu sighed.
"So, let me get this straight. I've just been born into a completely unfamiliar world, I'm apparently one of the most powerful beings of my kind, I'm leaking enough magicules to make myself a walking beacon, and I have no idea what the local power structure looks like."
He stared at the ceiling.
"…Wonderful."
For a moment, he said nothing.
Then his lips curled into a familiar, almost predatory smirk.
"But then again…"
His grey eyes, their sclera gleaming gold in the darkness, narrowed with amusement.
"When have I ever cared about who wanted a problem with me?"
He slowly rose to his feet.
The movement was effortless.
Too effortless, actually.
His body felt light, his senses sharp, and the unfamiliar energy circulating within him responded to his thoughts with an almost instinctive obedience.
Ryu looked toward the cave's entrance, where a faint glow illuminated the darkness beyond.
A new world.
A new body.
A new set of rules.
And, if his luck was anything to go by, a whole new collection of idiots who would eventually decide that he needed to die.
He couldn't help but smile.
"Whatever."
He took a step forward.
"I'll deal with the situations accordingly."
And with that, the Eighth Primordial began his first steps into a world that had absolutely no idea what kind of monster had just been born into it.
