The Reincarnated Assassin is a Genius Swordsman

“G-Grandfather?”

Raon’s eyes widened as he stared at Glenn’s straight back.

“How are you here…”

He’d been about to risk his life and use Demon King Advent because Larian was in mortal danger, but Glenn had appeared out of nowhere and blocked the Heavenly Demon’s Fist Strike.

He was so stunned he couldn’t even close his mouth.

“I can’t let it happen again, can I?”

Glenn nodded calmly, saying he’d prepared with Larian in case of an emergency.

“You’ve been through a lot.”

He smiled gently at Raon and Evelyn.

“I, I…”

Raon bit his trembling lip.

‘What should I say first?’

He wanted to explain everything, but Glenn’s smile made it hard to speak.

“We can talk about your story later.”

Glenn patted his shoulder like nothing was wrong, then turned back to the Heavenly Demon.

“Glenn Zieghart.”

The Heavenly Demon’s eyes, filled with flames of nothingness, lit up with joy as he let out a deep sigh.

“I didn’t expect you to come all the way here.”

He didn’t sound like an enemy—more like someone genuinely pleased to meet an old friend.

This was the first time someone hadn’t wavered while facing Glenn’s Energy Wave head-on. The Heavenly Demon’s martial prowess was lofty and refined, befitting his name.

“Should I call you Heavenly Demon now?”

Glenn tilted his head at the Heavenly Demon.

“Since your name has changed, it seems your behavior has changed as well.”

He frowned, displeased.

“The old you wouldn’t have bothered with children who weren’t up to your standards.”

Glenn clicked his tongue, saying he’d grown uglier than before.

“Since I’ve already acted, I won’t make excuses.”

The Heavenly Demon nodded, accepting that ugliness.

“However, the word ‘children’ doesn’t suit those two.”

He narrowed his eyes toward Raon behind Glenn.

“Because those ‘children’ you’re protecting are the ones who made The Fallen One end up like this.”

The Heavenly Demon spread his hand, floating a fragment of The Fallen One’s mask.

“……”

Glenn didn’t retract his heavy aura even after sensing The Fallen One’s soul faintly rising from the mask fragment.

“Even so, they still wouldn’t be up to your standards.”

He furrowed his brow deeper, as if that only stoked his anger.

“I have my reasons, but I don’t want to talk about them.”

The Heavenly Demon lifted both arms, making it clear he had no intention of explaining.

Gooooooo!

Glenn and the Heavenly Demon locked eyes, neither willing to yield an inch, and raised their Auras.

Kwarurururu!

Lightning bloomed from Glenn’s fingertips, wrapping the sky and raining red.

Kuuuuuu!

Black Fighting Spirit surged from the Heavenly Demon’s shoulders, shattering the earth and calling up boiling lava.

Catastrophes erupted from the sheer force of two absolute transcendents clashing.

“Let’s move back.”

Larian grabbed Raon’s arm and stepped away.

“You ignorant bastard. That freaking hurt.”

She frowned and shook her reddened palm, still stinging from clashing with the Heavenly Demon.

“Did the Magic Tower Master call the Head of House?”

Raon exhaled shallowly as he looked at Larian.

“To be honest, I thought Derus might come, but it worked out in the end.”

Larian chuckled, saying it was meant as a measure against Derus, not the Heavenly Demon.

“How did you…”

“I don’t believe in omens. I just judged from experience.”

She snorted, glancing at the fragment of The Fallen One’s mask.

“We’ll talk later. We need to move farther back.”

Larian said if they stayed near Glenn, not even bone fragments would remain, and retreated to where Evelyn and Mark Gorton were.

“Let the monsters fight each other.”

She was a monster herself, but she seemed to feel a clear gap between herself and Glenn or the Heavenly Demon.

“Are you okay?”

Raon approached Evelyn, collapsed on the ground, and Mark Gorton, kneeling unsteadily.

“I can manage…”

Evelyn smiled awkwardly, insisting she could manage.

“I-I’m fine too.”

Mark Gorton nodded, even as he vomited blood from internal injuries.

He couldn’t believe either of them were fine, so he kept a close eye on them.

“I’ve used up all my healing magic. Eat medicine for internal injuries.”

Larian produced round pills from the air and fed them to Evelyn and Mark Gorton.

“Raon, you too.”

She handed him one as well, like she was offering a piece of chocolate.

“……”

Raon chewed the medicine and looked at Glenn facing the Heavenly Demon.

‘Is he going to be okay?’

The Heavenly Demon had not only absolute power, but also Divine Authority. For the first time, Raon found himself worrying about Glenn.

“There’s no need to worry.”

Larian patted his shoulder, as if she’d read his expression.

“That man won’t lose. Especially…”

She smiled broadly.

“Never in front of you.”

– “That is correct.”

Wrath nodded heavily.

– “Instead of worrying about that lovesick old man, recover from your internal injuries.”

He clicked his tongue, saying there was no need to worry about Glenn. Hearing that, Raon felt a little more at ease.

Uuuuuung.

Raon ran the Ring of Fire and Ten Thousand Flames Cultivation, watching the Heavenly Demon standing before Glenn.

The Heavenly Demon didn’t spare this side a glance, as if his interest in Raon and Evelyn had vanished.

“Are you going to raise Eden now?”

Glenn lowered one eyebrow as he looked at the Heavenly Demon.

“No. I’m only here because of my pact with The Fallen One.”

The Heavenly Demon shook his head, lightly jingling the one remaining Heavenly Demon Bell.

“Isn’t it funny?”

He twisted his lips and looked at the mask fragment beside the bell.

“You claim to read celestial omens and know everything in the world, yet this is what you’ve become in the end.”

He tapped the fragment as if mocking The Fallen One, then slipped it into his uniform pocket.

‘As I thought…’

Raon frowned.

‘The Fallen One and the Heavenly Demon aren’t on good terms.’

From the Heavenly Demon’s tone alone, it was hard to believe they belonged to the same faction. Their relationship felt openly hostile.

“However…”

The Heavenly Demon turned his red eyes to Raon, strength gathering at his fingertips.

“I haven’t seen The Fallen One’s prophecies be wrong so far. It seems your grandson has something special about him.”

He licked his lips plainly, as if he still coveted Raon.

“Yes. He is special.”

Glenn nodded, acknowledging it without hesitation.

“But he’s not a vessel you can handle.”

He twisted his lips, saying Raon’s vessel was so vast even the Heavenly Demon couldn’t contain it.

“We’ll see about that soon enough.”

The Heavenly Demon smiled faintly and loosened his fist.

“Actually, now isn’t the time to clash with you. The great reader of celestial omens has decided something. But…”

He clenched his fist again, his eyes glowing red beneath his helm.

“I can at least get a taste, right?”

As the Heavenly Demon stepped forward, black Fighting Spirit flared like flames from his shoulders—darkness so heavy it swallowed light.

“That’s good.”

Glenn tilted his chin, arrogant.

“I wasn’t planning on letting you go easily either.”

As he said he needed to vent his anger, thunder and lightning struck from all directions, turning the night red.

“Let’s see if that name—‘the demon who ascended to the heavens’—is real.”

Glenn said he would become the heavens himself and drew Heavenly Drive from his waist.

“Can you handle it?”

The Heavenly Demon returned the words as they were, smiling coldly.

“Let’s see how long you can endure the laws of causality with that decaying body of yours.”

He extended his thinly clenched fist as if to say, begin.

Huuuuung!

It wasn’t even a heavy punch, yet Fighting Spirit surged and twisted space. It was a Fist Strike worthy of being called Divine Power.

Kuwahhhhh!

Glenn didn’t flinch even as the Heavenly Demon’s Fist Strike ripped through space and surged toward him. He calmly raised his left hand.

Paaaaang!

Glenn took the Fist Strike with only his left hand, without even lifting his sword.

“You talked so much. Is that all you’ve got?”

He shook his head, suppressing black Fighting Spirit with red Fighting Spirit.

“Good. I won’t be bored.”

The Heavenly Demon curled his lips, pleased.

Strangely, his stance wasn’t formal. It was loose and free, like an arena fighter’s.

Paaaaang!

As the Heavenly Demon unleashed his fist with True Enlightenment, space burst again and again, and a wave of black Fighting Spirit surged toward Glenn. It was ogre-like force that devoured light and Aura alike.

Chwaaaaa!

Glenn lightly slashed Heavenly Tremor as if practicing, and the Fist Strike split in two before sinking into the ground.

“They say you’re called Sword God now instead of Thunder God. I can see why.”

The Heavenly Demon smirked, amused. He flicked away the circular Fighting Spirit condensed on his finger and charged, his massive frame closing the distance in an instant.

Kuwahhhhh!

As Glenn erased the Fighting Spirit exploding before him with a Sword Strike, the Heavenly Demon lunged in from the left.

Huuuuung!

A Fist Strike slammed toward Glenn’s waist, so fast it felt like it had already landed the moment the fist extended.

“You’re not one to judge that name.”

Glenn replied evenly, flipping Heavenly Tremor—still holding firm from the earlier explosion—and placing it before the incoming fist.

Kuwahhhhh!

Heavenly Drive became an ultimate shield, showing not a hint of wavering even against the Heavenly Demon’s direct Fist Strike. It was the sword’s divine nature—erasing even a transcendent’s will.

“Good. You need to be able to do at least this.”

The Heavenly Demon pushed off with his toes and shot to Glenn’s right. The ground seemed to fold beneath him, like teleportation.

Kugugugugu!

Heaven-and-earth energy gathered on his clenched fist. In a world warped like a kaleidoscope, his fist fired like a brilliant flash.

Chiaaaaaang!

Glenn thrust Heavenly Tremor into the Fist Strike that crushed heaven and earth.

Pajijijijik!

Red lightning ignited along the silver blade, scorching the black Fighting Spirit. Lightning—the foundation of Glenn’s martial arts—forced the Heavenly Demon’s Fighting Spirit back.

“Ha!”

The Heavenly Demon shook off the red lightning that seemed to burn into his fist and stepped back. He smiled deeply as he looked at the blood flowing from the back of his hand.

“You’re definitely different. Different from anyone else.”

His eyes flashed with excitement as he drove his thick fist toward Glenn’s heart.

Huuuuuk!

Glenn stepped forward as well, refusing to give ground, and swung Heavenly Tremor blazing with red lightning.

Kuwahhhhh!

In Glenn’s duel with the Heavenly Demon, the waves of Aura and Fighting Spirit no longer spread outward.

In a transcendent world where sound and light vanished, sword and fist plunged for each other’s throats.

One sword technique split the horizon. One Fist Strike collapsed a mountain. It was a battle of martial god avatars—like a dream, not reality.

“Haa…”

Raon exhaled roughly as he watched the clash of true transcendents.

‘Can I reach that level?’

He’d been satisfied with stabilizing his transcendence, but seeing the real thing made him feel ashamed of his complacency.

‘When I think about it, I didn’t catch the Black Tower Lord or The Fallen One on my own.’

Chamber had exhausted the Black Tower Lord, and Evelyn had perfectly interpreted The Fallen One’s magic, letting him strike the weakness.

If he’d faced them alone, he would’ve been crushed.

‘And on top of that…’

Raon frowned as he watched the battle that seemed to twist space-time.

‘Those two aren’t going all out.’

Just as Glenn wasn’t using his Heart Sword, the Heavenly Demon was also hiding something.

‘Learn. I have to learn, even now.’

A duel between warriors who had transcended even transcendence was something you couldn’t witness just because you wanted to. He had to take at least one thing from it.

Heeeuuu.

As Raon tried to focus by resonating the Ring of Fire, he heard a sob from behind.

Dedeuk.

When he turned, Evelyn was clawing at the ground with blood-soaked hands.

“Evelyn?”

Raon grabbed her arm as she tried to tear the earth apart.

“What’s wrong?”

“It’s frustrating…”

Evelyn grit her teeth, head lowered.

“I said I was okay, but I’m so frustrated…”

She’d said it was fine to let The Fallen One go, but the anger inside her was unbearable.

“I barely caught him after five hundred years. How can this happen again!”

Red tears spilled from her eyes as she said that if The Fallen One slipped away now, she might never catch him again.

– “Madwoman….”

Wrath seemed to feel her emotions as well. He bit his lip and patted her back, as if he empathized after seeing her memories.

“……”

Raon bit his lip as he looked at Evelyn crying through blood and tears.

‘How pathetic.’

While he’d been thinking about learning from the clash of martial gods, Evelyn was reliving the dead, her past, and everything The Fallen One had destroyed.

Heat rose up his face at the shame of boasting he’d solve everything—and still achieving nothing.

“Did I say it earlier?”

Raon bit his lip and stood.

“I said I’d kill The Fallen One again if he came back. That promise…”

He smiled, baring his teeth, and walked toward the black fissure where Glenn and the Heavenly Demon fought.

“I’ll keep it now.”

“R-Raon?”

Evelyn shook her head quickly, as if asking what he meant.

“No! You’ll vanish without a trace too!”

Larian grabbed his arm to stop him.

“It’s fine. I’m not rushing in.”

Raon said he had enough chances to win. He set Heavenly Drive and the Wooden Wheel Sword on the ground, then drew the Soul Requiem Sword from behind his waist.

‘I have no choice but to use Sword Control.’

As Larian said, if he stepped directly between those transcendents, his body would turn to dust.

He had to aim for The Fallen One’s mask fragment from afar with Sword Control.

‘And with the Soul Requiem Sword.’

No other blade would do. Only the Soul Requiem Sword could cut The Fallen One’s soul right now.

“Don’t do it! Just don’t!”

Evelyn shook her head wildly, begging him to stay.

“I believe in you.”

Raon smiled at Evelyn, telling her not to worry, and slowly moved toward the battlefield.

‘Not yet.’

Glenn and the Heavenly Demon were trading martial arts like a warm-up. They still had plenty left.

‘Waiting is…’

Raon stroked the red blade of the Soul Requiem Sword and took a deep breath.

‘What I’m best at.’

“As expected.”

The Heavenly Demon curled the corners of his mouth inside his helm.

“You’re the only human on this continent who can satisfy me.”

He nodded, enjoying his exchange with Glenn.

“That’s how it’s been so far.”

Glenn shook his head coldly and split the Heavenly Demon’s Fist Strike with Heavenly Tremor’s sword energy.

“Now that I’m warmed up, shall we start properly?”

The Heavenly Demon lowered his clenched fist to his side. A tyrannical Energy Wave poured from his entire body, and the earth surged like waves from the Mana’s pressure alone.

“Come.”

Glenn set Heavenly Drive at center, and a magnificent red radiance that seemed to touch the sky rose from the silver blade.

Kugugugugugu!

Their grand Energy Waves spread endlessly, dyeing the world in light and darkness—martial gods ascending beyond transcendence into the realm of the absolute.

Kuwahhhhh!

The Heavenly Demon shattered the ground and advanced, eyes flashing with joy. His fist fell with terrifying weight, as if it carried the sky itself.

Kurururung!

Glenn’s Heavenly Tremor surged like a red thunderbolt. Crimson lightning lanced upward, splitting the clouded sky in two.

Kuwahhhhh!

Sword and fist collided, overturning heaven and earth. Thousands of cracks opened, and a storm of Aura and Fighting Spirit erupted.

Kwaddeudeudeuk!

Just as Glenn and the Heavenly Demon were about to drive sword and fist in to measure each other’s martial arts, a red dagger flew in silence.

It was the Soul Requiem Sword, carrying the subtleties of Sword Control.

“You taught your grandson….”

The Heavenly Demon frowned, fury flashing.

“Wrong! Glenn Zieghart!”

He swung the back of his left hand to deflect the Soul Requiem Sword.

But the Soul Requiem Sword pierced space before his hand could reach it and shot toward his chest.

“Hmph!”

Even in that extreme instant, the Heavenly Demon reacted—catching the sword in his fist.

Paaaaang!

However, the sword contained more than just the subtleties of the Sword Control And Spatial Sword. Raon’s will, honed to the extreme, mingled with the energy of vengeful spirits, giving rise to a blade of light that tore at the enemy’s soul.

Paaaaaang!

The tiny slash extending from the Soul Requiem Sword split the fragment of The Fallen One’s mask, which the Heavenly Demon was protecting, in half.

Kiaaaaa!

The Fallen One’s soul, lingering within the mask fragment, shrieked grotesquely and scattered into the air.

Kugugugugu!

For the first time since the fight began, the Heavenly Demon turned his gaze from Glenn to Raon. His eyes filled with rage and bewilderment as he gnashed his teeth.

“You bastard…”
