The Reincarnated Assassin is a Genius Swordsman

Paaaaang!

Raon stepped forward with his left foot and thrust Heavenly Drive. The flames blazing over the silver blade drew a black silhouette, as if piercing a hole through the sun.

It was the first form of the True Demon Sword Art: Sun-Piercing Red Glow, infused with the will to pierce the sun itself.

Chiaaaang!

Raon violently swung the blade, which had shot into the air, back down. Brilliant flames fell like a bolt of lightning, carving a massive crater into the North Sea. It looked like the caldera of a volcano. This was the Scorching Flame Split of the True Demon Sword Art.

Huuuuk!

Even after Scorching Flame Split, Raon continued to unfold the forms of the True Demon Sword Art in succession, controlling the sword and flames as naturally as his own limbs.

Due to the overwhelming power of the True Demon Sword Art, the glacier protected by Gold Dragon Parateus began to slowly melt.

“How does it look?”

The Blade Monarch asked the Sword Monarch without taking his eyes off Raon’s sword.

“We wanted mid-level proficiency, right?”

The Sword Monarch pressed her trembling lips down with her front teeth.

“I think he has far surpassed that level.”

She let out a hollow laugh, admitting that she didn’t know what had happened during the few days Raon had been left alone.

“It’s true that the linkage between forms is still lacking. However…”

The Sword Monarch lowered her eyebrows, looking slightly conflicted.

“The forms themselves aren’t lacking much. It means he knows exactly what the key elements of the True Demon Sword Art are.”

She nodded, noting that Raon accurately understood the essence of the True Demon Sword Art, where every single form was crucial.

“I’m thinking the same thing.”

Just as the Blade Monarch wore a faint smile, feeling a good omen—

Hwaaaaa!

After completing the True Demon Sword Art, Raon drew the Wooden Wheel Sword. The leaf-shaped guard froze white, and blue frost spread in all directions.

Chiaaaang!

Raon swung the Wooden Wheel Sword down gently, as if combing a woman’s hair.

It wasn’t the flow of a Blade Art, but a fluid motion like swordsmanship. However, its power was fierce and menacing enough to split and explode the glacier. This was the first form of the Demon Soldier Blade Technique, Blood-Stained Frost Fall, which possessed a brutality diametrically opposed to the flow of traditional martial study.

Paaaaang!

Raon slashed upward diagonally with the tilted Wooden Wheel Sword. Unlike the original flow of the Demon Soldier Blade Technique, the angle shifted slightly as it soared.

The second form, Demon War Whirlwind—which he had researched with the Blade Monarch to enhance its power and weight—revealed itself to the world for the first time.

Chiaaaang!

Stepping with a heavy True Step, Raon drew the forms of the Demon Soldier Blade Technique as if they were a single line.

Unlike the True Demon Sword Art, the precision of each individual form was lacking, but the linkage between them was flawless from start to finish, without a single tremor.

“How does it look to you?”

The Sword Monarch nudged the Blade Monarch’s back with her shoulder.

“…”

The Blade Monarch couldn’t answer immediately; the fingertips of the hand resting on his thigh trembled.

“The completion of the forms is lacking, but the linkage is as smooth as a single Blade Art. He isn’t merely aware of the true meaning of the Demon Soldier Blade Technique; he is manifesting it.”

He let out a long, deep sigh, saying that even the word amazing was insufficient.

“Moreover, he properly applied the parts we revised together.”

The Blade Monarch nodded, visibly moved by that part.

“I feel that this person could walk the path I could not.”

He wore a subtle smile, believing that Raon could reach the pinnacle of the Demon Soldier Blade Technique.

[Well, he’s decent…]

Gold Dragon Parateus tilted his head. However, contrary to his words, his eyes were shaking violently.

Having witnessed the martial arts of the Sword Monarch and Blade Monarch, he understood exactly how incredible Raon’s achievement was.

Ssssh.

After unfolding all the forms of the Demon Soldier Blade Technique, Raon rested the Wooden Wheel Sword, still blooming with frost, on his shoulder.

“You did great! It was beyond expectations!”

“I acknowledge you, Raon-nim.”

Just as the Sword Monarch and Blade Monarch stood up simultaneously to applaud Raon—

Raon raised Heavenly Drive and the Wooden Wheel Sword at the same time. Crimson flames blazed over Heavenly Drive, and the blade of the Wooden Wheel Sword was covered in blue frost.

Chiaaaang!

Heavenly Drive drew the first form of the True Demon Sword Art, Sun-Piercing Red Glow, creating a rift of flames in the air.

At the same time, the Wooden Wheel Sword fell, shaking the massive glacier. It was the first form of the Demon Soldier Blade Technique, Blood-Stained Frost Fall.

Kuuung!

Raon pivoted his ankle to the right, slashing down with Heavenly Drive while bringing the Wooden Wheel Sword upright. The lightning summoned by the flames split the glacier, and the blue frost cleaved the sky in half.

Hwaaaak!

Petals of flame and mists of frost swirled around Raon like a meteor shower.

Normally, these energies would have clashed and destroyed each other, but the Aura of the Diamond Earth Art intervened between the flame and frost, acting as a breakwater that allowed the pinnacles of the True Demon Sword Art and Demon Soldier Blade Technique to unfold.

Huuuuk!

The forms of the Demon Soldier Blade Technique and the True Demon Sword Art did not hinder each other’s flow at all, as if they had been a single martial art from the beginning, covering the heavens and earth with the trajectories of the sword and blade.

“Ah…”

“Is… is this the martial art of the true Sword-Blade Master…?”

The Sword Monarch and Blade Monarch looked on with eyes full of emotion, seeing the martial arts of the rivals they had fought their entire lives blending together to exert an even greater power.

The two forgot to breathe, completely immersed in the beauty and strength of the swordsmanship Raon was painting.

Huuuk.

Finally, after completing the linkage between the True Demon Sword Art and the Demon Soldier Blade Technique, Raon lowered both swords.

‘Fortunately, it worked.’

The linkage between the two was more natural than expected. As the memories of the past month flowed through his mind, a deep smile unconsciously formed on his lips.

》”You… you bastard…”

Wrath descended in front of him, his jaw trembling.

》”Did you intend to use swordsmanship and blade arts together from the very beginning?”

He stared with wide eyes, as if he had no idea.

‘Of course.’

Raon nodded calmly, as he had planned the linkage between the True Demon Sword Art and the Demon Soldier Blade Technique from the start.

‘I think it turned out a bit better than expected.’

Though the level of completion wasn’t perfect, he was reasonably satisfied with the result given the short amount of time, and the corners of his mouth curled up slightly.

》”No, you’ve never even tried it before!”

Wrath gaped, finding it nonsensical.

‘As I told you before, I’m a practical learner.’

Today was the first time he had unfolded the True Demon Sword Art and the Demon Soldier Blade Technique simultaneously, but since he had been taught the subtle principles of dual-wielding by Sheryl and had always swung two blades due to the Divine-Demonic Harmony State, it wasn’t that difficult.

》”This damn…”

As Wrath gnashed his teeth, the footsteps of the Sword Monarch and Blade Monarch approached.

Srrrung!

The Sword Monarch and Blade Monarch drew the Sword of Blazing Wave and the Blade of Frost Severity and stood before him.

Kuuung!

The two drove their respective weapons into the ground and knelt on their right knees.

‘Again? No, it’s different…’

It was a sight he had seen often, but there was something different this time.

The Sword Monarch and Blade Monarch weren’t looking at him as the descendant of the Sword-Blade Master, but with burning eyes directed toward the sword master known as Raon Zieghart.

“Sieran, descendant of the Sword Sect…”

“Yubert, descendant of the Blade Sect…”

The Sword Monarch and Blade Monarch spoke simultaneously and bowed their heads.

“We greet our Lord!”

“I look forward to working with you as well.”

Raon bowed politely to the Sword Monarch and the Blade Monarch.

“Please stand up. For people of your reputation, your knees are far too light.”

He told them he would only accept this today and helped them up.

“I’m only saying this now, but I never imagined I would serve such a young Lord.”

The Sword Monarch let out a hollow laugh, still feeling bewildered.

“Actually, I was planning to hand the True Demon Sword Art over to that man.”

She wore a thin smile, admitting she had considered making the Blade Monarch the descendant of the Sword-Blade Master.

“I knew.”

The Blade Monarch nodded calmly, as if he had noticed from the start.

“That’s why I only used the level of martial power appropriate for that situation.”

He lowered his hand, stating he had the same thought as the Sword Monarch.

“Anyway!”

“Hmm…”

The Sword Monarch and Blade Monarch looked at each other with soft smiles, appearing to have grown even closer over the past month.

[Ugh, cringeworthy!]

》”I can’t stand the sight of them…”

Gold Dragon Parateus and Wrath wrinkled their noses in unison.

“Let’s leave this place now. I think the glacier is about to collapse.”

Raon lightly tapped the melting glacier and gestured to the Sword Monarch and Blade Monarch.

“We must follow the Lord’s word.”

The Sword Monarch nodded in agreement.

“I’ve already packed my things, so we can leave immediately.”

The Blade Monarch said he had already finished preparing, as if he had decided to serve Raon as his Lord long ago.

“Then let’s go right away.”

Raon smiled faintly and gestured behind him.

“Evelyn! Please.”

“Okay!”

As if she had been waiting, Evelyn let out a clear shout and opened a Dimensional gate.

Wooong!

Behind the shimmering blue portal, the summit of Stehrin Mountain, where Sloth’s bed was located, came into view.

“This gate connects to the summit of Stehrin Mountain. Please enter.”

Raon raised his hand and pointed toward the gate.

“Well, we should see the damage we caused.”

The Sword Monarch nodded and stood before the gate.

“She is a highly skilled mage.”

The Blade Monarch let out a small exclamation of admiration at Evelyn’s mana composition.

[It’s a bit narrow for me to enter, isn’t it?]

Gold Dragon Parateus tilted his head while looking at the gate.

“Why on earth would you go through there!”

The Sword Monarch frowned, as if he were talking nonsense.

“You clean up everything here and fly over!”

She stomped her foot, telling him to handle the aftermath of the site.

“Hmm, that’s true.”

The Blade Monarch nodded calmly.

[No, you guys made this mess, so why do I have to clean it…]

“Let’s go!”

The Sword Monarch ignored Parateus and entered the gate first.

“Make sure you clean up thoroughly.”

The Blade Monarch also gave Parateus a sharp look and followed the Sword Monarch.

[Why on earth won’t that evil-demon couple just die!]

Parateus trembled his fists in frustration.

[They’ve far exceeded the average human lifespan!]

While cursing the Sword Monarch and Blade Monarch, he faithfully began to melt the remaining glacier and clear away the cabin and its traces.

》”What a pushover lizard!”

Wrath gnashed his teeth, thinking there was no bigger pushover than this.

‘…Indeed.’

He looked just like someone.

Raon nodded awkwardly and entered the Dimensional gate.

‘I’m really curious.’

He wondered what kind of story had led an Ancient Dragon to become both a friend and a slave.

“Wow, we really broke a lot! There’s nothing left.”

“We certainly made a mistake.”

The Sword Monarch and Blade Monarch sighed deeply as they surveyed the scenery of Stehrin Mountain that they had demolished.

Grrrrung!

As soon as Raon stepped out of the gate, something like a grub popped out of the ground.

“P-Palace Lord!”

It was Dorian. He crawled toward Raon and grabbed his pants.

“Why did you take so long!”

His cheeks were slightly sunken, and his eyes were brimming with tears.

“Why have you become so thin?”

Raon blinked as he helped Dorian up. His once chubby cheeks had vanished, making it look as if he had been starving for a long time.

“I brought plenty of food.”

“I… I was too scared to eat…”

Dorian pointed toward Sloth, who was sleeping with a blanket covering him up to his head. It seemed he had been trembling in fear for a whole month.

“I told you it’s fine…”

Raon let out a hollow laugh.

“He doesn’t touch people.”

“How can it be fine when he’s a Demon King!”

Dorian sniffled, saying he still hadn’t adjusted. He looked pitiful, but honestly, his appearance was much better now.

“Where is Evelyn?”

Raon turned his head, calling for Evelyn.

“I’m here!”

Evelyn jumped down from the air with a bright smile. She brushed back her perfectly neat hair and waved her finger.

“Sorry. For making you wait a whole month.”

Raon bowed to Evelyn. Seeing Dorian’s state, he figured Evelyn might not be in a great mood, so he apologized immediately.

“I’m fine.”

Evelyn shook her head, as if such words were unnecessary.

“Because I was always with you.”

As she said that, she wore a chilling smile.

》”Hieeeek!”

Wrath shrieked and scrambled away in terror.

“A-always?”

Raon’s jaw trembled as he looked at the smiling Evelyn.

“Of course! I was watching you from nearby the whole time.”

Evelyn shrugged, as if telling him not to worry.

“The sword training, the Aura linked cultivation—it was all wonderful. I would have been happy watching for a year.”

She smiled, saying she had lost track of time while watching him.

“I… I see…”

Raon subtly shifted his gaze toward Wrath.

‘Did you feel her?’

》”I-I had no idea at all!”

Wrath shook his head violently.

》”It seems the Madwoman’s stalking ability has risen to the level of a Demon God!”

He clutched his head, stating that he could no longer sense Evelyn’s presence.

“Fufu.”

Evelyn wore a thick smile, as if this past month had been simply wonderful.

“Ahaha…”

Raon laughed awkwardly and slowly backed away.

“S-Sloth?”

To change the subject, he pulled back the blanket of the sleeping Sloth and woke him up.

“Let’s wake up now.”

“Mmm…”

Sloth slowly lifted his eyelids, appearing to have had quite a satisfying sleep. Unlike Dorian, Sloth’s face had a healthy glow.

“I’ve dealt with the noise. There won’t be anything to wake you up now. As for the circumstances…”

“Then… it’s fine…”

Sloth nodded without even listening to the explanation.

“You don’t need to hear it?”

“If it’s… solved… then it’s… fine…”

He let out a long yawn, as if trusting Raon.

“I guess so.”

Raon let out a hollow laugh. He didn’t know why beings like Wrath and Sloth, who were called Demon Kings, were so naive.

“I have one favor to ask of you too. Will you do it?”

“What… is it…?”

Sloth blinked, telling him to speak. He seemed to want to hear it quickly so he could go back to sleep.

“A war with the Archangels will break out soon. I’d like to borrow your strength then.”

Raon looked at Sloth, biting his lip slightly.

“Archangels… somehow…”

Sloth nodded, saying he had a dream where he felt the aura of Archangels from a very distant place.

“If I explain the circumstances…”

“I’ll do it… however…”

Without hearing the details, he said he would do it and looked at Raon.

“Fighting… Archangels… is dangerous… dimensional balance… Divine Authority… ah, too tedious…”

Sloth slowly shook his head, as if he had already grown tired of explaining.

“To pass everything… and for me… to fight… there are things… I need…”

“Things you need?”

“Normally… impossible… but you… can do it…”

He spoke with heavy lips while looking at Raon’s wrist.

“That is…”
