The Reincarnated Assassin is a Genius Swordsman

Paaaaaang!

Raon didn’t miss the fleeting instant when Glenn’s sword and the Heavenly Demon’s fist collided. He hurled the Soul Requiem Sword with everything he had.

‘Damn it…’

His head felt like it was about to split.

He’d burned through so much Aura and mental strength that even moving Sword Control made his thoughts sway.

Pain surged—unbearable—but he endured, recalling Evelyn’s tear-streaked face.

“You taught your grandson…”

Even while blocking Glenn’s Sword Strike, the Heavenly Demon sensed the Soul Requiem Sword’s movement and reached out with his left hand.

“Wrong! Glenn Zieghart!”

‘Now!’

The moment the Heavenly Demon raised his hand, Raon unleashed the Light Wind Style with the Soul Requiem Sword.

Chiaaaaaang!

His unique swordsmanship—piercing space and targeting the enemy’s vitals—slipped past the Heavenly Demon’s defense and flashed before his chest.

“Hmph!”

As expected of Eden’s absolute being, the Heavenly Demon didn’t miss a sword that transcended space. He seized the Soul Requiem Sword in his grip.

‘As expected.’

Raon had predicted this.

‘If he can’t stop this much, the name Heavenly Demon would be a joke.’

Knowing he couldn’t pierce the Heavenly Demon with Light Wind style alone, he’d thrown the Soul Requiem Sword from the start—not Heavenly Drive, not the Wooden Wheel Sword.

‘Because I have a last resort.’

He could communicate with the vengeful spirits within the Soul Requiem Sword. With a single thought, he asked for their help—and raised an invisible blade.

Chiaaaaaaaang!

The black sword conjured by the red vengeful spirits wasn’t his.

It was Glenn’s Heart Sword. Or more accurately, an imitation of Glenn’s Heart Sword.

A sword that severed the enemy’s soul. Following that noble, magnificent flow, he honed the blade of his heart together with the vengeful spirits.

‘Kuhhhh!’

His skull throbbed like it would crack, and his three dantians twisted as if they’d explode. He forced down the blood rising in his throat and focused.

‘Only one chance.’

He had to drive it all the way through and stab.

The soul sword he and the Soul Requiem Sword had formed was small and weak.

It would struggle to cut even an ordinary person’s soul—but it was enough to sever The Fallen One’s soul, which existed only as faint fragments.

Woooooong!

Raon resonated the Ring of Fire—quivering as if it might explode—to sharpen his concentration.

‘There!’

He felt The Fallen One’s soul from the pocket where the Heavenly Demon Bell was kept.

Trusting his senses, he thrust the soul sword at that lingering soul.

Paaaaaang!

Even the Heavenly Demon hadn’t imagined he could form a blade that cut souls. He didn’t even try to defend—only watched as the fragment of The Fallen One’s mask shattered.

Kiaaaaaaaaaaaaa!

A shriek like thousands of metal shards splitting apart erupted from inside the mask fragment.

Even The Fallen One, who’d never screamed while dying, couldn’t endure pain that struck the soul itself.

Kuaaaaaaaaaaa!

The Fallen One screamed as if paying the price for mocking countless lives—then melted away.

“Kuh…”

The moment Raon confirmed The Fallen One had become gray mist, he collapsed where he stood.

‘I-it’s over.’

With that last strand of soul severed, not even the Heavenly Demon could revive The Fallen One.

– “You crazy bastard!”

Wrath stared at him, eyes wide.

– “You are a true madman!”

Shocked by the psychological warfare that had outplayed even the Heavenly Demon, he pounded Raon’s shoulder with his round hands.

– “To aim for that single gap! You’re insane! Well done!”

Wrath was genuinely impressed, grinning brightly.

“You…”

The Heavenly Demon looked at Raon with anger and embarrassment, as if his pride had been wounded.

“Keuh!”

The moment Raon met that gaze, he vomited the black blood he’d been forcing down.

‘T-this is really the limit.’

He wanted to retrieve the Soul Requiem Sword from the Heavenly Demon’s grasp, but he couldn’t move even a finger.

Maybe because he’d overexerted himself while already injured, even breathing was hard.

“Taught wrong?”

Glenn shook his head, smiling as if pleased.

“No. He’s my grandson—who’s grown better than anyone else in the world.”

His bold voice rolled like thunder, and lightning surged, carving a red line that split sky and earth.

Kuaaaaaaaa!

With a strike that seemed to carry the wrath of the gods, black Fighting Spirit split apart, and the Heavenly Demon’s solid body was driven back, crashing into the cracked earth.

Kuaaaaaaaaaaaaaang!

A streak of red lightning erupted from below, stretching endlessly, as if heralding the end of the world.

“Keuh…”

As the Heavenly Demon fell beneath the ground, Raon braced himself and vomited blood again. His condition was so bad that even the vibrations felt like they were twisting his insides.

“Are you okay?”

Larian was already behind him, supporting his body. She used nature’s Mana to loosen the stagnant energy clogging his insides.

“I-I’m okay.”

Raon barely nodded.

“You really…”

Larian stared at him like she couldn’t believe it.

“You’re a man who does what he says. I’m seeing you in a new light!”

She laughed cleanly, looking at the empty air where The Fallen One’s soul had melted away.

“I-I was lucky.”

Raon waved a hand, saying it wasn’t skill—just luck.

“I couldn’t have done it alone.”

He offered a faint smile, meeting Evelyn’s eyes.

‘

‘

‘

“R-Raon.”

Evelyn pressed her dry lips together as she watched Raon smile—then vomit blood.

‘Promise…’

Raon had promised he’d kill The Fallen One again if he returned, but she’d honestly thought it was just something he said to comfort her.

After the Heavenly Demon revived The Fallen One, she’d given up on killing him. She swallowed everything down and accepted that there was no choice.

But Raon rose on exhausted legs, as if he meant to keep his word, and stepped into the battlefield of the martial gods—where Glenn and the Heavenly Demon were clashing.

Eyes set like he would stand again even if he fell a thousand times, he advanced—then split the soul of The Fallen One, protected by the Heavenly Demon, with a single dagger.

Watching a man who barely had the strength to walk risk his life to kill The Fallen One for her sake, tears she couldn’t contain spilled out.

Sniff…

Evelyn wiped her tears and squeezed her eyes shut, wanting to see Raon properly.

‘Mom…’

Was it because The Fallen One had died? In the brief moment her eyes closed, her mother’s face surfaced.

Sella—always hazy, like she was hidden behind mist—was smiling brightly, as if telling her she’d done well.

“Haa…”

Evelyn slowly opened her eyes, still holding Sella’s smile in her heart.

Raon nodded calmly at her. As if he were telling her he’d kept his promise, tears fell again.

“Thank you. Thank you so much…”

For the first time, gratitude rose from her heart, not her head. All she could do now was offer it honestly.

“……”

Raon smiled faintly, like he was fine. Seeing him accept her thanks even while blood pooled at his lips, gratitude swelled even deeper.

‘My life…’

Evelyn clenched her weakened hand into a fist.

‘No. I’ll dedicate my soul to you too.’

She struck her chest where ten Circles spun, engraving the oath of a transcendent.

===

Kuaaaaaaaaang!

The Heavenly Demon rose from the deeply carved fissure like a cliff bearing the mysteries of the beginning. A deep sword mark ran across his chest—Glenn’s blade carved into him.

“Haa…”

He looked at Raon without even caring about a wound split like a canyon.

“Hm…”

Raon let out a strained breath as he stared at that body.

‘What kind of monster is that?’

To still be standing after taking Glenn’s sword—his body and mind were absurd beyond belief.

‘No… it’s not like it did nothing.’

His momentum had clearly dulled. The wound had definitely affected him.

“Amazing.”

The Heavenly Demon nodded as if genuinely impressed.

“To forge a sword that cuts souls—even if you borrowed the power of a dagger.”

He looked at the Soul Requiem Sword in his hand and curled his lips.

“I understand why he told me to take you. You have both power and talent.”

The anger in his eyes shifted into joy, and he tossed the Soul Requiem Sword down at Raon’s feet.

“You… Keuh!”

Raon spat black blood as he tried to reach for it. His body was in ruin; even speaking was difficult.

“Stop looking.”

Glenn stepped to the side, blocking the Heavenly Demon’s gaze from Raon.

“You’ll wear him out.”

He shook his head, denying him even the chance to watch.

“A Sword God acting like a fool for his grandson… no one would believe that story.”

The Heavenly Demon smiled faintly and tossed the shattered mask fragment onto the ground.

“Was that surprise attack also for that grandson?”

He stroked the wound on his chest, lips curling.

“You tried to lay hands on children beneath your level, so I gave you the same treatment.”

Glenn shook his head like he didn’t feel even the slightest shame.

“Is that so.”

The Heavenly Demon nodded, faintly smiling, and the bleeding from his chest began to slow.

“It seems both you and I have changed a lot.”

He withdrew the Heavenly Demon Bell from his pocket.

“Originally, the Heavenly Demon Bell is an object bound by an oath between The Fallen One and me.”

He clicked his tongue while looking at it.

“Thanks to your excellent grandson, I couldn’t keep my promise to the one who asked me to save him—so I have to pay the price.”

Even as he said he had to pay it, he didn’t look upset.

If anything, the pleased curl of his lips made arrogance feel tangible.

“Price or not, you won’t lay a finger on Raon.”

Glenn shook his head, making it absolute.

“It’s true your grandson is impressive—but not now.”

The Heavenly Demon waved a hand, as if Raon didn’t interest him in his current state.

“Turning the wheel of fate the way you want is certainly impressive. But what I’m interested in now is…”

He raised a finger toward Glenn.

“You. Glenn Zieghart.”

A chilling laugh slipped from within his helm.

“I planned to trade a few moves and end it, but since The Fallen One is dead, I have to trade a proper one.”

He put strength into his fingertips, as if everything before had been play.

“I’ll accept it.”

Glenn nodded calmly, as if inviting him to come as hard as he wanted.

“It’s refreshing.”

Tension rippled through the air as the Heavenly Demon rolled his shoulders, loosening up. His movements were free and magnificent, like they followed the providence of the universe.

He pointed his left fist at the sky and set his right fist at his waist.

A fighting stance—the posture of a supreme ruler, harmonizing attack and defense, heaven and earth, yin and yang.

Oppression poured out of him, as if compressing a thousand years into a single breath. The world itself seemed to hold still under that presence.

Chiaaaaaang!

Glenn raised Heavenly Tremor with calm composure despite the Heavenly Demon’s magnificent Energy Wave.

Scarlet lightning burned along the silver blade as if it would purge all evil, and he aimed sword energy at the Heavenly Demon’s neck.

It looked like a basic posture, yet Glenn’s existence distorted space-time. Even the Heavenly Demon could ignore everything else and focus only on him.

The ultimate of martial arts.

Glenn’s sword—at its peak—created an absolute Energy Wave that invaded the realm of the gods and poured out as clear light.

Kugugugugugu!

Their momentum climbed into the sky, and a crack formed as if the world were being split in two.

In a realm of transcendence slowly turning gray, killing intent sharpened between the two.

Kuuuuung!

In that suffocating confrontation, the one who moved first was the Heavenly Demon. The moment his fist moved, Mana solidified as if time had stopped.

Kuaaaaaaaaaaaaa!

A massive Mana wave surged from his fist, warping nature’s Mana itself. It looked like chaos blooming—beyond simple destruction.

Kuuuuuuuuu!

He wasn’t just throwing a punch. It felt like he meant to crush Glenn’s existence with a fist forged from soul itself.

Hwaaaaaaaa!

Glenn’s presence swelled in response, resisting that tyrannical momentum that shook heaven and earth.

The magnificent thought rising from his soul formed a noble Energy Wave, as if erasing the chaos the Heavenly Demon brought.

Chiaaaaang!

As Glenn extended Heavenly Tremor toward the Heavenly Demon charging with a black Fist Strike, a red light bloomed—so intense it seemed to twist space-time.

The crimson radiance around the Sword God was vast and mysterious, like it didn’t belong to this world.

Not Aura, but thought.

An absolute sword that cut the essence of the soul, not the body.

Heart Sword and Limitless Aura.

The martial arts of absolute beings who walked different paths collided head-on.

Kuaaaaaaaaaang!

The instant red sword and black fist met, the sky and earth shattered as if the universe’s providence had been twisted.

This wasn’t just a contest of techniques.

It was a clash of souls—everything those peerless martial artists had built as humans.

Raon carved the collision that seemed to shake his soul into his eyes and drew a ragged breath, like he might die.

‘Their colors are different.’

Glenn honed his sword to its limit, forging a Heart Sword that severed the enemy’s soul.

The Heavenly Demon refined the concept of martial arts itself, forging a soul and body that wouldn’t break under anything.

It wouldn’t be wrong to call it a spear and a shield—except the spear could become a shield, and the shield could become a spear.

Raon watched the battle as if a new myth were being written, not missing a single moment—forgetting even to breathe.

Tuuuuuung!

At the peak of their clash, when darkness like an abyss bloomed between them, golden flames blazed within Raon’s sunken eyes.
