The smell of blood filled the air.
Flames devoured the battlefield while the sky burned red like the end of the world. Broken swords and fallen warriors covered the ground, their bodies lying motionless among the ashes.
In the middle of the battlefield stood a young warrior in dark armor.
His body was covered in wounds, and blood slowly dripped from his sword. Yet his glowing blue eyes still burned with rage.
Around him, the once glorious army of his kingdom had fallen.
Everything was gone.
His friends, his comrades, the people who trusted him, all of them were dead.
And the one responsible stood right in front of him.
A tall man dressed in silver armor walked slowly toward him, a cold smile on his face.
"You look pathetic," the man said calmly.
The young warrior clenched his teeth.
"You betrayed us..." he said with a trembling voice.
The man laughed.
"Betrayal? No. I simply chose the winning side."
The young warrior's heart burned with anger.
"You were my brother."
For a moment, silence filled the battlefield.
Then the man raised his sword.
"In this world," he said coldly, "only power matters."
Before the young warrior could react, the sword pierced his chest.
Pain exploded through his body.
His strength disappeared instantly as he fell to his knees. Blood poured onto the ground beneath him.
The battlefield slowly grew darker as his vision blurred.
So this was the end.
His kingdom destroyed.
His friends dead.
His life meaningless.
But then...
A strange voice echoed inside his mind.
Cold. Ancient. Mysterious.
"Do you wish for another chance?"
The young warrior's fading eyes widened.
The voice continued.
"Do you wish to return... and take revenge?"
His heart trembled.
Revenge.
The word burned inside his soul.
"Yes..." he whispered weakly. "I want revenge."
Suddenly, a powerful light exploded around his body.
The battlefield disappeared.
The flames vanished.
Everything turned into darkness.
And then...
He opened his eyes.
But he was no longer lying on the battlefield.
Instead, he was lying on a wooden floor inside a small room.
The young warrior slowly sat up, breathing heavily.
His body had no wounds.
His hands were clean.
Confused, he looked around the room.
"This place..."
It looked familiar. Too familiar.
Then his eyes fell on a small mirror hanging on the wall.
He stood up and walked toward it slowly.
When he looked into the mirror, his eyes widened in shock.
The face staring back at him was younger.
Much younger.
"This is impossible."
He touched his face with trembling fingers.
"I returned...?"
Memories began flooding his mind.
This was the past.
Five years before the war.
Five years before the betrayal.
Five years before everything was destroyed.
A cold smile slowly appeared on his face.
"Good."
His eyes began glowing faintly with blue light.
"If fate gave me another chance..."
He clenched his fists tightly.
"This time... I will destroy everyone who betrayed me."
The era of revenge had begun.
Chapter 2: The Second Chance
Morning sunlight entered through the half-open window, but the young man did not move.
He stood before the mirror for a long time, staring at the face he had once forgotten.
A younger face.
A weaker body.
But behind those eyes was not the same naive boy who had lived in this room five years ago.
Behind them was a man who had seen kingdoms burn.
His name was Kael Draven.
Once, he had been known as the kingdom's brightest sword.
Later, he had become its greatest failure.
And now, he had returned.
Kael slowly sat on the edge of the bed, trying to calm the storm in his mind.
He remembered everything.
The war.
The betrayal.
The blood.
The screams.
And above all, the face of the man who killed him.
Darius.
The one he had once called brother.
Kael lowered his head, and his hands trembled slightly.
Not because of fear.
Because of hatred.
A knock suddenly came from the door.
"Young master? Are you awake?"
Kael froze.
That voice.
He knew it.
"Come in," he said.
The door opened carefully, and an old servant stepped inside carrying a tray of food.
For a moment, Kael could not speak.
The old man was still alive.
Garen.
In his previous life, Garen had died protecting him during the fall of House Draven.
But now, he was standing right there, healthy and breathing.
"Young master?" Garen asked with concern. "You look pale. Did you not sleep well?"
Kael looked away quickly.
"I'm fine."
Garen placed the tray on the table.
"Your father asked me to remind you. The family gathering starts at noon."
Kael's eyes narrowed.
The family gathering.
He remembered it clearly now.
This was the day everything began.
The day he was humiliated in front of the entire Draven family.
The day he was called talentless.
The day Darius first stepped into his life with a smile and poison hidden behind kindness.
Kael let out a slow breath.
"I understand."
Garen hesitated for a moment, then spoke softly.
"Young master... no matter what they say today, please do not take it to heart."
Kael stared at him.
Even now, the old servant cared for him.
In the past, Kael had been too blind and proud to notice such loyalty.
This time would be different.
"Thank you, Garen," he said quietly.
The old servant looked surprised, then smiled warmly.
After Garen left, Kael walked to the window and looked outside.
The Draven estate stretched before him like a sleeping beast. Stone courtyards, training grounds, high walls, and noble halls. A place filled with wealth, power, and smiling snakes.
He knew every corner of it.
He also knew who among them would one day sell his family to the enemy.
One by one, their names surfaced in his memory.
His uncle, Marrok Draven.
His cousin, Lira.
Three knights of the household.
And Darius, the outsider who would slowly win everyone's trust before cutting out the kingdom's heart.
Kael's expression turned cold.
"Since heaven sent me back," he murmured, "I will not waste this chance."
He closed his eyes and searched within his body.
In his previous life, he had awakened his Flame Core at the age of nineteen.
That was considered late.
Because of that, he had always lagged behind true geniuses during his youth.
But now he knew the method.
He knew the breathing technique.
He knew the dangerous path that others feared.
If he started now, he could awaken years earlier.
Kael sat cross-legged on the floor.
He slowed his breathing.
Inhale.
Exhale.
He guided his thoughts toward the center of his chest, where all spiritual power slept.
At first, there was nothing.
Only darkness.
But Kael did not stop.
Again.
And again.
Minutes passed.
Sweat formed on his forehead.
Pain slowly spread through his chest like burning needles.
Then—
A spark.
Tiny.
Weak.
But real.
Kael's eyes snapped open.
He smiled.
"It's there."
The Flame Core had not awakened yet, but the seed was already responding.
That alone changed everything.
In his previous life, he had wandered in confusion for years.
Now, he had found the path in less than an hour.
Suddenly, footsteps echoed in the hallway.
Then a mocking voice sounded from outside his room.
"Kael! Don't tell me you're still hiding in there."
Kael's face darkened.
He recognized that voice too.
Ronan.
His older cousin.
A coward who loved humiliating the weak.
Kael stood up slowly.
"Come out already," Ronan shouted. "The family is waiting to laugh at you."
Kael walked to the door and opened it.
Ronan stood there in expensive blue clothes, wearing his usual arrogant grin.
For a few seconds, the two stared at each other.
Then Ronan laughed.
"What's with that face? Did you finally realize how useless you are?"
In the past, Kael would have lowered his head and stayed silent.
Today, he did not.
Kael stepped forward and looked straight into Ronan's eyes.
"You talk too much."
The smile on Ronan's face stiffened.
"What did you say?"
Kael leaned slightly closer.
"I said... enjoy laughing while you still can."
For the first time, Ronan took half a step back.
Something in Kael's eyes had changed.
Something dangerous.
Kael walked past him without another word.
Behind him, Ronan stood frozen in confusion.
And for the first time since returning, Kael felt the future begin to shift.
Chapter 3: The Name of the Traitor
The central hall of House Draven was already filled when Kael arrived.
Long tables stood beneath crystal chandeliers. Noble family members sat in groups, talking in low voices while servants moved quietly between them.
The moment Kael entered, several gazes turned toward him.
Some were indifferent.
Some were mocking.
Some were filled with open disdain.
Kael ignored them all.
He had seen far worse than noble ridicule.
At the head of the hall sat his father, Lord Arthen Draven.
A stern man with sharp features and tired eyes.
In Kael's previous life, his father had died with a sword in hand while defending the capital.
Even in death, he had stood like a wall.
Looking at him now, alive and unbroken, Kael felt something tighten in his chest.
"Kael," Arthen said. "Take your seat."
Kael bowed his head slightly and sat at the lower end of the table.
Immediately, whispers began.
"So he really came."
"He still has the nerve to show his face?"
"I heard he failed again in yesterday's training."
"What a disgrace to House Draven."
Kael heard every word.
But his expression did not change.
Then another figure entered the hall.
A young man with silver hair and calm eyes.
He wore a gentle smile and moved with the grace of a noble knight.
Darius.
The hall seemed to brighten around him.
Several people greeted him warmly.
Even the elders nodded with approval.
Darius placed a hand over his chest and bowed politely.
"My apologies for being late."
"It is fine," Arthen said. "Take your seat."
Kael watched him in silence.
The same smile.
The same calm voice.
The same false warmth.
No one here knew that this charming young man would one day drown the kingdom in blood.
But Kael knew.
And that knowledge was more dangerous than any weapon.
Darius glanced at him and smiled.
"Brother Kael, it is good to see you."
Kael looked at him coldly.
"We are not brothers."
The hall fell silent.
Several nobles frowned.
Darius blinked in surprise, then laughed softly.
"My mistake. I only meant it as a sign of friendship."
Ronan snorted from the side.
"Friendship? Why would someone like you lower yourself to befriend him?"
A few people chuckled.
In the past, Kael would have burned with shame.
Now, he simply watched.
This gathering had always seemed chaotic and cruel to him as a boy.
But now he could see the currents beneath the surface.
Who aligned with whom.
Who laughed too quickly.
Who remained quiet.
Who looked at Darius with trust.
It was all useful.
Then Marrok Draven, Kael's uncle, spoke with a fake smile.
"Since everyone is gathered, perhaps the young ones should demonstrate their progress. It would bring life to the hall."
Several elders agreed.
Kael already knew what was coming.
A public comparison.
A stage prepared for humiliation.
Arthen's face darkened slightly, but he said nothing.
The first few young nobles stepped forward one after another, showing sword forms and basic aura control.
Polite applause followed.
Then Ronan displayed his technique with exaggerated confidence and received praise from Marrok.
Finally, all eyes turned to Kael.
"Well?" Marrok said. "Will my nephew not show us his talent?"
Silence spread across the hall.
Kael rose slowly.
He could feel the expectation.
They wanted entertainment.
They wanted failure.
He stepped into the center of the hall.
"What would you like me to show?" he asked calmly.
Ronan laughed.
"Anything. Assuming there is anything worth showing."
Kael said nothing.
An elder brought a crystal orb used to measure spiritual resonance.
In the past, Kael had touched that orb and produced almost no response.
The memory still remained sharp.
He placed his hand on the orb.
For one second, nothing happened.
Then a faint red light appeared within the crystal.
Small.
Very small.
But visible.
Murmurs spread immediately.
"Did it react?"
"Impossible. I thought he had no affinity."
"It's weak, but it's there."
Kael removed his hand.
The room was no longer laughing as freely as before.
Marrok's eyes narrowed.
Ronan's smile faded.
Darius, however, remained calm.
Too calm.
That alone told Kael enough.
Darius had always hidden his thoughts well.
But Kael had spent years at war reading faces before battle.
He saw it now.
A tiny flicker in Darius's eyes.
Interest.
Not surprise.
As though he had just noticed a piece on the board move unexpectedly.
Good, Kael thought.
Notice me.
Fear me.
Remember this moment when your plans begin to fail.
Then Darius stood and clapped lightly.
"Well done," he said with a pleasant smile. "It seems Kael has been working harder than we realized."
The others slowly followed with reluctant applause.
Only Kael knew how poisonous those words were.
Praise from Darius was never simple praise.
It was a way to draw attention.
A way to make others suspicious.
A way to set traps under the mask of kindness.
Kael looked at him and smiled faintly.
"Thank you."
For the first time, Darius's smile paused for half a heartbeat.
Just enough.
Kael turned away.
Inside his mind, one thought echoed clearly.
I found you.
Chapter 4: Hidden Rage
After the gathering ended, Kael did not return to his room.
Instead, he walked alone through the western side of the estate, where old stone paths led toward an abandoned garden.
Few people came here.
That was why he had chosen it.
The air was quiet. Dry leaves moved beneath his boots. The statues in the garden were cracked with age, and the fountain at the center had long since stopped flowing.
Kael stood before it and closed his eyes.
His pulse was still steady, but inside him, rage moved like a storm.
Seeing Darius again had reopened old wounds.
The betrayal no longer felt like a distant memory.
It felt fresh.
Raw.
Alive.
Kael gripped the edge of the broken fountain until his knuckles turned white.
"I should have killed you the moment I saw you," he whispered.
But he quickly forced himself to breathe.
No.
That would be foolish.
He was weak now.
Far too weak.
If he acted only on anger, he would die before changing anything.
Revenge required patience.
Planning.
Strength.
He straightened slowly and released the stone.
"In my last life, I lost because I was blind," he said to himself. "This time, I'll be worse than my enemies."
He sat beneath a dead tree and began circulating his breathing method again.
The Flame Breathing Art.
A forbidden technique he had discovered years later in a ruined battlefield shrine.
It was unstable and dangerous, but its results were terrifying.
Ordinary people trained by absorbing spiritual energy slowly over years.
The Flame Breathing Art consumed weakness like fire consumed wood.
It hurt more.
It risked more.
But it advanced faster.
Kael inhaled deeply.
Heat gathered in his chest.
He guided it down his veins with careful control.
Pain followed immediately.
It felt as though hot metal was being pushed through his body.
His muscles trembled.
Sweat dripped down his neck.
Still, he did not stop.
He had endured death once already.
This pain meant nothing.
Time passed.
When he finally opened his eyes, the sunlight had shifted.
A faint red aura shimmered for an instant around his hand before vanishing.
Kael looked at his palm.
The energy was still weak, but more stable than before.
At this rate, he could truly awaken the Flame Core much earlier than in his previous life.
A voice suddenly interrupted his thoughts.
"So this is where you were."
Kael turned.
A girl stood at the entrance of the ruined garden.
She wore a simple noble dress, her long dark hair tied behind her back. Her expression was calm, but her eyes were sharp.
Lira Draven.
His cousin.
In the future, she would help deliver military secrets to their enemies.
At the moment, however, she looked like nothing more than a quiet noble lady.
Kael rose slowly.
"What do you want?"
Lira glanced at the cracked ground near him.
"You left the hall too quickly. People started wondering."
"I didn't know my movements were so important."
"They aren't," she replied. "But your change is."
Kael remained silent.
Lira stepped closer.
"You were never this confident before. What happened?"
Kael gave her a faint smile.
"Maybe I got tired of being looked down on."
"That alone doesn't explain your eyes."
His smile faded.
Her instincts were sharp.
Even as a young woman, she had already been difficult to read.
In the past, Kael had underestimated her because she hid behind elegance and silence.
He would not repeat that mistake.
"Then stop trying to explain me," he said.
For a moment, the two cousins stared at each other.
Then Lira unexpectedly smiled.
"A warning, then."
Kael said nothing.
She turned slightly and looked back at the estate.
"Ronan is angry. Uncle Marrok is suspicious. And Darius..." She paused. "Darius is interested."
Kael's voice became colder.
"Should that concern me?"
"It should concern anyone." Lira looked at him carefully. "He makes people lower their guard. That is what makes him dangerous."
Kael almost laughed.
So even now, some part of her had already noticed Darius's nature.
Interesting.
"Thank you for the warning," he said.
Lira gave a small nod and began walking away.
But before leaving, she stopped.
"You changed overnight, Kael. I don't know why. But if you're planning something..." She looked at him from the corner of her eye. "Be careful who sees it."
Then she disappeared beyond the garden wall.
Kael stood in silence.
In his previous life, Lira's betrayal had come much later.
At this point in time, perhaps she had not yet fully chosen a side.
Or perhaps she was simply better at hiding it than everyone else.
Either way, she would remain on his list.
No one would be trusted easily.
As evening approached, Kael returned to his room.
But he found someone waiting outside.
Darius.
He stood beside the door with his usual calm smile, as if he belonged there.
Kael's eyes sharpened.
"What do you want?"
Darius raised both hands lightly.
"Nothing hostile. I only came to speak."
"Then speak."
Darius studied him for a moment.
"You've changed since yesterday."
Kael said nothing.
Darius continued, his tone warm and friendly.
"That is a good thing. A man should not remain weak forever. If you truly wish to improve, I can help you."
There it was.
The offer.
In the previous life, Kael had accepted without hesitation.
Darius had trained with him, guided him, supported him.
And by doing so, he had entered every corner of Kael's trust.
Never again.
Kael opened the door to his room.
"I'm not interested."
For the first time, Darius's smile became thinner.
"You reject me without even listening?"
Kael looked at him directly.
"Yes."
Then he stepped inside and shut the door in Darius's face.
Outside, silence remained for several seconds.
Inside, Kael stood still in the dark room.
Then he let out a slow breath.
The game had begun.
And this time, he had made the first move.
Chapter 5: Awakening the Flame Core
For the next seven days, Kael vanished from everyone's attention.
He attended meals when necessary, answered only when spoken to, and avoided all unnecessary contact.
To the rest of the household, it seemed as though his brief change in attitude had already faded.
That was exactly what he wanted.
Every morning before sunrise, he went to the abandoned garden.
Every night after the estate had gone quiet, he trained again inside his room.
He slept little.
He ate only enough to keep his body standing.
All his focus was on one thing.
Awakening the Flame Core.
The process was brutal.
His veins felt as though they were being burned from within.
Sometimes, blood rose in his throat after training.
Sometimes, his hands shook so violently he could barely hold a cup.
But with each session, the spark in his chest grew stronger.
On the seventh night, Kael sat alone on the floor of his room.
Moonlight spilled across the wooden boards.
His breathing was deep anThe heat inside his body had reached its limit.
He could feel it clearly now.
The barrier.
A final wall between dormant talent and true power.
Kael opened his eyes slightly.
"This is it," he murmured.
He placed one hand over the center of his chest and inhaled.
The Flame Breathing Art moved through his body with dangerous speed. Energy gathered from every corner of his flesh and converged inward.
Pain exploded.
Kael bit down hard enough to draw blood.
His vision shook.
His heartbeat became wild and violent.
Still he pushed forward.
More.
A little more.
The heat in his chest became unbearable.
Then—
Crack.
A sound like glass breaking echoed inside his body.
Kael's eyes flew open.
Red light burst from his chest and spread across his skin in thin burning lines before fading.
For a brief moment, the room felt filled with invisible fire.
Then everything became still.
Kael remained frozen, breathing hard.
He slowly lowered his hand.
And smiled.
The Flame Core had awakened.
He could feel it clearly now.
Deep inside his chest, a tiny core of burning energy pulsed like a living ember.
Weak for now.
But alive.
Real.
He had done it years earlier than in his previous life.
A laugh escaped his lips.
Low at first.
Then sharper.
"Good..." he whispered.
At this speed, the future would not merely change.
It would break.
Kael stood and walked toward the mirror.
He looked pale, exhausted, and slightly thinner than before.
But his eyes...
His eyes had changed.
There was now a faint red glow hidden behind the blue.
A sign of awakening.
A sign of power.
A sign that the useless young master of House Draven no longer existed.
Suddenly, a sharp knock came from the door.
Kael's expression hardened instantly.
"Who is it?"
"It's me," Garen said from outside. "Young master, forgive the interruption, but Lord Arthen requests your presence immediately."
Kael frowned.
"At this hour?"
"Yes. There has been an incident."
Kael opened the door.
Garen looked unusually tense.
"What happened?"
The old servant lowered his voice.
"One of the family's external warehouses was attacked. Several guards were killed."
Kael's eyes narrowed.
This had happened before.
He remembered it now.
In his previous life, everyone believed it had been a raid by common bandits.
But months later, hidden evidence had revealed the truth.
It had been a test.
A small attack arranged by enemies connected to Darius, meant to measure House Draven's response and weaknesses.
Back then, no one had noticed.
This time, Kael would.
"I'm coming," he said.
As they walked through the estate corridors, Kael's mind moved quickly.
If the warehouse attack was happening now, then the hidden pieces were already moving much earlier than most people realized.
That meant he had less time than expected.
Inside the main strategy chamber, several important figures had already gathered.
His father stood at the center with a grim face.
Marrok was there.
Ronan too.
And beside them, as always, stood Darius.
When Kael entered, a few eyes turned toward him in annoyance.
But Arthen spoke first.
"You came quickly."
Kael bowed slightly. "You called for me, Father."
Arthen studied him for a moment, then nodded.
"Listen carefully. Our eastern warehouse was attacked tonight. Five guards are dead. The attackers escaped."
Marrok crossed his arms.
"It was likely a simple robbery."
Kael looked at him.
"No."
The room went still.
Marrok frowned. "What did you say?"
Kael took one step forward.
"It was not a simple robbery."
Ronan scoffed. "And how would you know?"
Kael ignored him and looked at his father.
"If it were ordinary thieves, they would have taken goods and fled as fast as possible. But if guards were slaughtered and the attackers still escaped cleanly, then they were testing the estate's reaction speed."
Silence followed his words.
Arthen's gaze sharpened.
Darius remained calm, but Kael noticed his fingers stop moving for just a moment.
Tiny.
But enough.
Kael continued.
"This was planned."
Marrok's face darkened.
"You speak boldly for someone who knows nothing of real battle."
Kael turned to him.
"Maybe. But I know this was not random."
Arthen raised a hand, ending the dispute.
Then he looked at Kael for several long seconds.
Finally, he said, "Interesting."
Those single words changed the air in the room.
For the first time, Lord Arthen Draven was no longer looking at his son with disappointment.
He was looking at him with attention.
And Darius saw it too.
Kael met Darius's gaze across the room.
Neither smiled.
Neither looked away.
The ember in Kael's chest pulsed quietly.
His power had awakened.
His enemies had begun to move.
And soon, the first real blood would be spilled.
