The Reincarnated Assassin is a Genius Swordsman - Chapter 720

Raon focused all his attention on Glenn’s swordsmanship, forgetting even to breathe.

‘What is this…?’

There was no overwhelming aura, no mysterious technique, and no intense intent. Glenn’s Heavenly Tremor sword simply moved forward in complete stillness.

Yet, the result brought by that single, slender blade was anything but ordinary.

The radiant attacks unleashed by the White Blood Cult Leader and the Fallen One were sliced apart. The breath of the Dragon Lord was erased, and the deathly aura from Derus Robert melted away into nothingness.

Even the colossal sword projection of the Sword Saint, which had seemed capable of severing the heavens and earth, was broken cleanly in two.

‘Is something like this… even possible?’

The miraculous slash shattered everything Raon had learned and understood about martial arts.

Ssss…

Glenn lowered his sword, which had cut through everything before it.

“This sword… is the *Heart’s Sword*.”

With those words, Glenn gave Raon a smile—one unlike any he had shown before.

“Heart’s Sword…”

Raon looked again at the world created by Glenn’s sword.

A sword not only capable of cutting through auras, techniques, or enemies but one that erased everything into nothingness—a transcendental sword that turned all into void.

– *Heart’s Sword, huh.*

Wrath, observing the scene, narrowed his eyes.

– *That’s a fitting name.*

‘A fitting name?’

– *Indeed.*

The small round spirit nodded solemnly and extended one of his stubby fingers.

– *That old man’s sword contains something far more profound than aura, technique, or intent.*

‘What’s more important than those?’

Though Raon thought he might know the answer, he waited for Wrath to say it.

– *Life and soul.*

Wrath prodded Raon’s chest lightly with his small hand.

– *That old geezer has imbued his sword with his entire life, his soul, and the essence of every moment in between.*

A glimmer of satisfaction appeared on Wrath’s face as he added:

– *It’ll be difficult to determine victory now.*

‘Difficult to determine victory?’

Wrath had always claimed he could easily defeat Glenn. For him to admit otherwise… it could only mean that Glenn now stood on the same plane as him.

Raon swallowed hard, looking at Glenn. His crimson eyes, though usually stern, now shimmered with warmth. That unfamiliar kindness tugged at Raon’s chest.

“What… what even is that?”

Ogram muttered, his disbelief apparent.

“What kind of sword technique is this?”

Even the typically composed Lecross, the King of Balkan, furrowed his brows.

“It is a sword, and yet… it is not,” he murmured, as if perceiving something beyond what he saw.

“Are you alright?”

Lecross spoke softly, concern coloring his voice as he looked at Glenn.

“I am.”

Glenn nodded calmly, as if nothing was out of the ordinary.

“What are you all waiting for? We need to make sure those bastards are dead!”

Chamber, now floating midair, clicked her tongue in irritation.

“We can’t let those damned lizards escape! If they do, I’ll hunt them down myself and skin them alive!”

Her frustration seemed directed not at the corrupted Five Demons but at the Dragon Lord trailing behind them.

“Let’s move!”

Grabbing Lecross by the neck, Chamber turned into a bolt of lightning and disappeared.

– *What are you waiting for? Chase after them!*

Wrath waved his little hand eagerly, his eyes gleaming.

– *This might be your only chance to feast on dragon meat!*

Raon exhaled a long sigh. Wrath might have seemed impressive just moments ago, but now he was back to his usual food-obsessed antics. He brushed the spirit aside and glanced at Glenn.

The old man looked calm, as if he already knew the outcome of the battle that had just concluded.

“Aris, Karoon, Sylvia.”

Glenn called out to the three as he glanced back at them.

“What did you see in my sword?”

His hands folded behind his back, Glenn patiently waited for their responses.

“I saw boundless freedom.”

Aris’s eyes glimmered with confidence as she answered.

“A sword that can extend endlessly in any direction, as if it had no limits.”

Her excitement was visible in the slight blush on her cheeks.

“I saw the majesty of a ruler.”

Karoon placed his trembling hand on his chest and bowed.

“A sword with absolute power, capable of cutting through anything in its path.”

His crimson eyes burned with newfound resolve.

“I… I felt…”

Sylvia hesitated, struggling to find the right words. Her lips quivered slightly as she finally spoke.

“I felt… sadness and bitterness.”

Her nose reddened as she lowered her head, as if surprised by her own response.

“I see.”

Glenn stroked his chin thoughtfully, his gaze turning toward Raon at last.

“And what did you feel, Raon?”

“I…”

Raon met Glenn’s gaze—those crimson eyes that mirrored his own.

“I felt warmth in your sword. It was a sword that could cut through everything, yet I sensed kindness and a desire to protect…”

Though he knew his words might sound foolish, Raon spoke truthfully.

“Warmth, is it?”

Glenn smiled—an expression so rare that it startled those around him.

‘Everyone felt something different…’

The freedom Aris sensed represented the days when Glenn had roamed the continent, witnessing and experiencing countless wonders.

The majesty Karoon perceived was the fierce dominance Glenn had wielded when he shattered all before him and ruled the battlefield.

The sadness and regret Sylvia felt echoed the burdens Glenn carried after leaving the world of martial arts, haunted by his past mistakes.

‘And the warmth Raon felt…’

Glenn’s gentle smile deepened.

‘That is who I am now.’

He no longer regretted the past. All he wished was for Raon, Sylvia, and the children of the Zieghart family to live happily.

Even if that meant his presence would fade, becoming nothing more than a foundation for their future, he would gladly accept it.

“That’s right.”

Suppressing the surge of emotion in his chest, Glenn offered Raon a heartfelt smile.

“Lord?”

Raon’s hand shot out instinctively, grabbing the torn sleeve of Glenn’s robe. Something inside him whispered that if he let go, the old man would vanish.

Thwap.

Glenn gently tapped Raon’s head before stepping forward.

“Clear out the remnants of the Five Demons. Today, the name of the North-South Union will be wiped from this continent.”

“Yes, sir!”

The Zieghart swordsmen pounded their chests in unison and charged toward the union’s headquarters.

Having witnessed Glenn’s divine swordsmanship firsthand, their eyes now shone with reverence and unwavering loyalty.

“Lord… are you really alright?”

Raon walked beside Glenn, swallowing nervously.

“For now, I am.”

Glenn glanced at Raon’s trembling hand and shook his head, his expression calm.

“There are still things I need to tell you, things I need to teach you. And I have a promise to keep, don’t I?”

His smile was serene, like the setting sun at the end of a long day.

Raon bit his lip, feeling that something had shifted irreversibly within Glenn.

‘For now?’

—

“Hey, uh…”

Muston stood on the bank of the now-silent Label River, his jaw trembling slightly.

“I don’t mean to be rude, but… doesn’t it seem like our Sword Saint just dives headfirst into trouble like a moth to a flame?”

He blinked in disbelief.

“I mean… to show up and immediately get cut down by Glenn Zieghart’s sword… What even…”

Muston exhaled a breath of disbelief.

“You’re not wrong,” Rektor murmured, slowly lowering his gaze.

“But I think I understand why.”

Simply crossing swords with Glenn could elevate one’s martial prowess to new heights. For someone as obsessed with the sword as the Sovereign, it was a natural choice.

Rektor gazed at Glenn’s back and let out a sigh.

‘In the end… he’s truly achieved it.’

The Heart’s Sword Glenn had shown was a dream—a pinnacle sought by countless sword masters.

It was not merely a martial technique but a manifestation of life and soul, transcending the limits of human achievement.

‘How envious I am…’

Even though Rektor had long abandoned his martial dreams for the sake of Raon and Sylvia’s happiness, he couldn’t help but feel a twinge of envy.

Watching Glenn place a reassuring hand on Raon’s shoulder, Rektor absentmindedly touched the hilt of his sword.

‘It seems you’ve finally made up your mind.’

For the first time, Glenn’s gaze toward Raon was steady—without a trace of hesitation.

‘I just hope… you take good care of him.’

Though… it seemed there wouldn’t be much time left.

“Master, what will you do now?”

Muston scratched his head and approached Rektor.

“With the Sword Saint dead…”

He trailed off, gazing at the still waters of the Label River.

“If he’s dead, we’ll need to retrieve his body. And if he’s alive…”

Rektor gripped the hilt of his sword tightly without finishing his sentence.

“What? That’s the path Lord Raon should take.”

Muston nodded and moved toward the other side of the river.

“Raon, Sylvia.”

Rektar smiled warmly at Raon and Sylvia, standing next to Glenn.

“Be happy.”

With those words, he offered his blessing to his grandson and daughter-in-law and disappeared into the dark forest.

—

“Two ancient dragons are dead.”

Chamber returned to the Label River, flicking her fingers.

“The corpses are a mess, and the Dragon Hearts? Completely shattered. Whoever named it Heart’s Sword—what a fittingly awful name.”

She let out a short, incredulous laugh.

“The Lord?”

Glenn narrowed his eyes, gazing into the distant sky.

“Gone.”

Chamber frowned.

“That damned lizard—always the first to flee.”

She sneered as if mocking him.

“Becoming enemies with dragons… This feels surreal.”

Lecross rubbed his temples in disbelief.

“Isn’t it better this way?”

Ogram grinned, placing a hand on Lecross’s shoulder.

“I never liked their hypocritical neutrality. Now we can break their necks openly.”

He clenched his fists, already envisioning new trophies from their hides.

“And the others?”

Glenn turned toward Chamber, his voice calm.

“The Sword Saint? Not a trace. He’s likely dead. As for the White Blood Cult Leader…”

Chamber grimaced as if disgusted.

“There was a field soaked in white blood, but I wouldn’t believe that cockroach is dead.”

She shook her head, certain the Blood Cult Leader would be the last to fall.

“And the Fallen One escaped.”

Chamber clicked her tongue, clearly irritated.

“And that bastard in the dragon helmet?”

“Alive,” Glenn replied curtly.

“Alive?”

“Yes. The bracelet he threw expanded the death energy and gave him a way out.”

Recalling the moment, Glenn narrowed his eyes.

“Of course,” Raon muttered, nodding calmly.

“There’s no way Derus would die here.”

Raon had known from the beginning that Derus wouldn’t fall so easily.

“But…”

Now, there was finally proof—a chance to unmask Derus and bring Robert’s downfall. Determined, Raon clenched his fist.

“You did well.”

Glenn placed a hand on Chamber’s shoulder.

“Well, someone had to do it.”

Chamber waved her hand dismissively but stole a glance at Glenn.

“You can’t keep using that sword, right?”

“…No.”

Glenn nodded quietly.

“Figured as much.”

Chamber pulled a lollipop from her pocket and popped it into her mouth.

“There’s a similar concept in magic. I think I understand now.”

Crunching down on the candy, she nodded in realization.

“Enough talk!”

Ogram clapped his hands loudly, pointing toward the now-abandoned North-South Union headquarters.

“What are we doing with that place? You won, so you need to think about what comes next.”

“You thinking that far ahead, muscle-head grandpa?” Chamber widened her eyes in mock surprise.

“What was that, punk?” Ogram flexed his arms and scowled.

“Hm.”

Ignoring the exchange, Glenn walked past them toward the riverbank.

“Come out.”

“….”

Despite his call, the water remained still.

“It’s okay. Don’t be afraid—come out.”

At his reassurance, bubbles rose from the water, and a young member of the Blue Wave Tribe peeked out. It was Garam.

“Garam!”

Raon quickly stepped between Glenn and Garam.

“He’s not an enemy. He’s my friend and helped me.”

“I know.”

Glenn raised a hand, signaling that he had expected this.

“Why did you help, despite the danger?”

Glenn narrowed his eyes, noticing the blood seeping from Garam’s shoulder.

“Because we’re friends!”

Without hesitation, Garam shouted his answer.

“I see.”

Glenn smiled softly and gave a small nod.

“When it’s dangerous, that’s when friends help each other.”

He raised a finger, pointing toward the river where the North-South Union base stood.

“Do you know who originally owned this land?”

“N-No…”

“It belonged to the Blue Wave Tribe.”

“Oh…”

“I’ll return it to you.”

Glenn knelt and extended his hand toward Garam.

“H-Huh?”

Dazed, Garam slowly reached out and grasped Glenn’s thumb.

“Stay close to him,” Glenn said, gently stroking Garam’s head before standing up.

“Lord…”

“I’m tired. Let’s head back.”

Glenn turned his back, ready to leave. He seemed sincere about returning the river to the Blue Wave Tribe.

“Ra-Raon!”

Garam called out in excitement, running up to him.

“Is it true? Is this really ours?”

“Yes. Though it might be more of a partnership.”

Glenn likely planned to establish a branch here, ensuring both the river and the tribe would be protected.

Now, Garam and the Blue Wave Tribe no longer had to hide in the depths of the Gazel River.

“Wooohooo!”

Garam threw his arms up in joy, shouting in excitement.

“Thank you, Raon!”

“No, I should thank you.”

Raon ruffled Garam’s hair, smiling.

– You’d thank him but not me?

‘Hm?’

– Hm? Hmm?! Have you lost it? I saved your life! Where’s my… oh?

Mid-rant, Wrath suddenly froze, shivering.

– M-My ribs ache…

‘Ribs? You have ribs?’

– Obviously. Oh no, it’s coming! It’s coming!

At Wrath’s urgent cry, Raon quickly expanded his senses.

But it wasn’t an enemy.

[You have accomplished an incredible feat!]
[You saved a transcendent from the brink of death!]
[A being of a higher realm has acknowledged your prowess….]
[All stats are increasing….]
[New traits unlocked….]

– Aaaagh!

Wrath screamed as a flood of messages overwhelmed him.

– I knew it! This blasted system is obsessed with you!

He flailed wildly, foaming at the mouth as he cursed the messages.

‘You’re unbelievable….’

Sighing, Raon calmed his senses—only to widen his eyes as he scanned the notifications.

‘Wait… what’s this?’

(TL Note: Wow! What a fitting end for this arc. So no more tsunder grandpa now?)
