The Reincarnated Assassin is a Genius Swordsman

‘This is…’

Raon chewed his lip as he recalled the sender of the short, concise letter.

‘It’s from Merlin.’

It wasn’t just the clean, refreshing scent clinging to the paper. The moment he saw the words of gratitude scribbled on the back, her face came to mind.

– “Th, that’s the crazy woman’s letter?”

Wrath looked shaken by the letter alone, his eyelids trembling.

‘Yeah. Merlin always said she was going to look for Eden.’

Merlin would often disappear, saying she would find Eden Headquarters, which had relocated after she left, and the hidden Heavenly Demon.

There had been no word from her for a while, but it seemed she’d finally found Eden’s location.

– “Indeed. Her handwriting is as chaotic as if earthworms crawled across the page. It suits a madwoman.”

Wrath nodded, muttering that it looked like the writing of someone not in her right mind.

“No, that’s not it…”

He studied the letter more closely and let out a low groan.

‘You’re right. It’s not that she can’t write—she was in such a hurry that this was all she could manage.’

Raon had seen Merlin’s handwriting back when she stayed in Zieghart.

Her penmanship looked like something from a book written centuries ago—yet the strokes themselves were straight and neat, almost printed.

The fact that the location of Eden and the words of gratitude were scrawled like this meant she was in serious danger.

– “Then she’s being chased.”

‘I think so too. She probably tried to gather more information after finding the headquarters, got spotted, and had to run.’

It seemed Merlin had discovered that Eden was beneath the crater at the summit of White Spirit Mountain. While trying to learn more, someone must have found her.

‘If that weren’t the case, she would’ve come to me herself instead of sending a letter.’

With Merlin’s personality, if she weren’t being pursued, she’d have shown up in animal form and startled him.

The fact that only a letter arrived—no true form, no animal—made the urgency obvious.

‘There’s also the chance it’s a trap…’

But I have to go anyway.

If Merlin was in danger, he had to move, even if it was bait.

Squeeze.

Raon read the letter again, his fingertips tightening until the yellow paper crumpled as if it might tear.

‘Thank you for treating me like a person?’

I haven’t done anything for you yet.

For a long time, Merlin had thought of herself as something other than a person.

Not like a dragon that elevated itself and looked down on humans as insects—rather, she saw herself as something lower, keeping close to animals instead.

Merlin, recorded in the continent’s history, had abandoned her position as a royal archmage and sided with monsters. There were also rumors that she had been devoured by a demon from birth and killed her parents on the spot.

It all seemed connected.

‘How pathetic.’

If touching a wound makes it burst, then we should’ve dealt with it together.

He regretted never asking about her past, telling himself it was for her sake.

‘I’m such a damn fool.’

He had received so much help from Merlin, yet he’d done nothing for her. He sneered at his own cowardice.

– “You stupid bastard!”

Wrath frowned as if asking what he was doing.

‘I know. I know this isn’t the time for that.’

Raon nodded, grinding his teeth.

‘But I don’t know what to do.’

He knew where Eden Headquarters was, but he couldn’t figure out how to act.

There was no dimension door near White Spirit Mountain. By the time he reached it, everything would be over.

No— even if he could get there right now, there was no guarantee Merlin would still be there.

‘Wrath.’

Raon let out a heavy breath and looked at him.

– “Hmm…”

Wrath frowned and shook his head.

– “Even this King can’t do anything in the human realm, let alone the Demon Realm.”

He lowered his gaze, saying all he could do was spread his Aura Sense in the area.

‘Then what should I do…?’

Raon was biting down hard enough to crack his teeth when—

“Lord?”

Mark Gorton approached.

“Are you alright?”

His face was dark, as if he’d been watching the whole time.

“Ah, it’s nothing. I’m…”

Raon was about to say he was fine, but he swallowed as his eyes landed on the entrance to the Head of House Conference behind Mark Gorton.

‘The Head of House Conference…’

That’s it. That’s the only way right now.

If he went to the nearest dimension door and ran from there, he’d be late. He needed to borrow the strength of Glenn and the other Four Kings—whether it worked or not.

“Burren, Martha, Runaan. Please guide them to Mirtan Village.”

Raon said he had something to take care of and asked the three of them to help.

“What? What’s going on—”

“Understood.”

Burren stopped Martha from continuing and nodded. He seemed to realize immediately that this was serious.

“I’m sorry. I should be the one guiding you.”

“Ah, no.”

Latiru, reading his expression, waved it off and said it was fine. Honestly, Raon didn’t even know what his own face looked like right now.

“Then…”

Raon apologized to everyone and returned to the Head of House Conference.

“I will go with you.”

Mark Gorton fell in behind him and bowed his head.

“No. I’ll go alone.”

Raon refused firmly. If this were a family mission, he might have considered it, but this was personal—and urgent.

“I am your Guardian, Lord. It is my duty to follow you, whether it is personal or official. If I fall behind, you may abandon me.”

Mark Gorton bowed again, as if he’d read Raon’s thoughts.

“…Understood.”

Raon let out a short sigh. He couldn’t refuse after appointing Mark Gorton as his Guardian.

“Let’s move.”

He shoved the rising thoughts aside and ran to the audience chamber.

—

“…And that’s how he caught an Ancient Dragon and returned already. Isn’t it admirable that he keeps his word?”

Glenn nodded toward the blue screen floating near the ceiling of the audience chamber.

“Who would’ve imagined Raon would move faster than us? He didn’t just reduce the enemy’s numbers—he brought back a definite clue!”

He spread his arms wide, as if this achievement went far beyond catching a dragon. His lips curled high, like he was genuinely pleased.

“Haa…”

Chamber bit down on candy as her image flickered on the blue screen.

“I wondered why you activated the emergency contact network, but it’s just to brag about your grandson? I’m going crazy.”

She shrugged, looking dumbfounded.

“…But our Raon isn’t hurt, is he?”

Even so, Chamber raised her brows, worry slipping through.

“At this level, it wouldn’t be strange to brag all day! Just accept it!”

Ogram clapped, declaring it incredible.

“But where’s the protagonist? I want to see his face.”

His eyes darted across the blue screen, like he was trying to spot Raon.

“To have the Light Wind Palace Swordsmen catch an Ancient Dragon… the Lord of Light Wind Palace is not only a martial artist, but an outstanding commander as well.”

King Lecross chuckled, saying he couldn’t find a single flaw.

“As expected, he’s amazing. I want to see the inside…”

Magic Tower Lord Larian murmured, as if whispering to herself. Her eyes glittered strangely beneath her hood.

“Don’t even think about doing anything weird.”

Chamber bared her white teeth, warning her not to touch Raon.

“Th, that’s not what I meant.”

Larian dipped her head slightly, hiding those sparkling eyes.

“Lord. What clue did you discover about the Four Demons?”

King Lecross smacked his lips, saying that was what he was most curious about.

“Yeah. Tell me. We need to prepare right away.”

Ogram rubbed his hands, saying he should send sorcerers who could move in secret.

“The clue Raon brought back about the Four Demons is…”

Glenn was just about to speak, lips still curled—

Koo-ooo-ooo-ng!

The doors of the audience chamber slammed open, and Raon and Mark Gorton strode in.

“Raon…?”

Glenn’s eyes widened at how different Raon looked.

“Raon’s here?”

Chamber snapped her head around, as if she might leap out of the blue screen.

“Suddenly?”

King Lecross lowered his brows, surprised.

“Raon!”

Ogram waved immediately, delighted to see him.

“I apologize for barging in.”

Raon bowed deeply to Glenn and the heads of the Four Kings.

“I have found the location of Eden Headquarters.”

He stepped forward, facing the blue screen.

“The location of Eden Headquarters?”

Glenn’s jaw dropped, as if he couldn’t have imagined it.

“Eden Headquarters is said to be beneath the crater at the summit of White Spirit Mountain. It needs confirmation, but it’s likely certain.”

Raon bowed his head, asking them to dispatch personnel who could move in secret.

“H-how did you learn that?”

Chamber blinked, dumbfounded.

“Someone sent me the information. So I have something to ask right now.”

Raon held out Merlin’s letter toward Chamber.

“Is there any way you can tell me where the sender of this letter is?”

He’d never heard of magic that could trace the sender of an object, but he had no other choice.

“Hmm…”

Glenn, seeing Raon’s rigid expression, looked to Chamber.

“Is there such magic?”

“I’m an expert in space magic, but there’s no spell like that.”

Chamber shook her head. She said she’d never even thought of such a thing.

“Ah…”

Raon bit his lip until it bled, watching Chamber’s image shake.

‘Damn it…’

Was I wasting time?

He regretted not running for the nearest dimension door from the start.

“Understood. I’ll be on my way—”

“Wait.”

Chamber raised a hand as Raon turned with unsteady legs.

“I can’t do it, but there’s someone who can handle that kind of perverted magic.”

She lifted a finger and pointed at Larian’s screen.

“Isn’t that right?”

“Mm…”

Larian slowly raised her gaze and studied the letter in Raon’s hand.

“W-was it sent by magic?”

She tapped her finger, as if that detail mattered.

“Yes. It fell on my head a little while ago.”

“J-just let me take it for a moment.”

As Larian reached out, the letter in Raon’s grasp appeared on her screen.

“Eden Headquarters… beneath the crater at the summit of White Spirit Mountain. And…”

She didn’t read the words on the back. She simply stared for a moment.

“Ah. There’s a very faint trace of mana. I think I can do it.”

She nodded, saying Merlin’s mana remained because not much time had passed.

“Really?”

Raon’s heart hammered, because he’d expected nothing.

“Y-yes. I can, but I need to prepare. It’ll take time.”

Larian shook her hood slightly, saying it would be difficult, but possible.

“I’m counting on you. Please tell me where she is.”

“I-I can send you there.”

Larian raised her hand, saying she could not only locate the sender, but transport him to the place the letter was sent from.

“B-but later…”

Her dazed eyes flashed with a cold light.

“Can you do me a favor?”

She nodded, saying she’d send him no matter what if he agreed.

“Understood. Anything.”

Raon nodded without hesitation.

“No! She’s the least normal among us!”

Chamber shook her head, telling him to refuse.

“She might dissect you!”

“It’s fine.”

He couldn’t think about what came after. He had to move, even if it meant selling his soul to a demon or an angel.

“…It seems that child is being chased.”

Glenn lowered his brows, as if he’d realized who the sender was.

“I’d rather go myself. As long as I don’t overdo it.”

He rose from his throne, ready to act.

“N-no.”

Larian parted her lips, gaze lowered.

“I-I can only send someone I can control with this magic.”

She shook her head, saying she couldn’t send Glenn because he was stronger than her.

Hearing that, Raon could roughly guess what the spell was originally meant for.

“Don’t worry.”

Raon shook his head at Glenn.

“I won’t do anything like directly invading Eden. I’ll save her and come right back.”

He rested a hand on his sword hilt, asking him to trust him.

“Hmm…”

Glenn’s lips moved, but he didn’t give permission, still worried.

“D-don’t worry.”

Larian shook her head.

“I don’t know the exact location, but where this letter was sent from isn’t near White Spirit Mountain.”

She flicked the hand holding her staff, saying it was far from White Spirit Mountain.

“More than anything, I’m worried it could be a trap.”

King Lecross narrowed his eyes, saying the letter itself might be bait.

“Th-that’s fine too. I’ll be watching.”

Larian snapped her fingers, saying she’d observe and move him away immediately if it became dangerous.

It seemed she intended to secure the favor she’d demanded, no matter what.

“Since she says so, trust me just once.”

Raon bowed to Glenn.

“Haa, I can’t help it.”

Glenn let out a long sigh, as if he’d accepted he couldn’t stop him.

Chiiiik.

About twenty minutes later, Larian engraved a red magic circle—like it had been drawn in blood—on Merlin’s letter and handed it over.

“I-if you place your hand on the circle, you’ll move to where the letter was sent.”

Larian smacked her lips, saying he could leave right away.

“That kind of perverted magic…”

Chamber shook her head, calling it impressive and absurd.

“Then I’m going.”

Raon bowed to Glenn.

“If you’ve decided, bring her back no matter what.” (T/N : Awww… our grampa really had taken a liking at Merlin)

Glenn’s heavy gaze settled on Raon.

“Because I want to hear her call me Grandfather again—after all this time.”

He nodded, telling him to do it properly if he’d made up his mind.

“Yes. I will bring her back, no matter what.”

Raon pressed a hand to his chest, as if making an oath.

“Let’s go.”

He gripped Mark Gorton’s shoulder and unfolded the letter with the circle.

“I-if something happens, call my name.”

As Larian brought her hands together, the letter tore into thousands of fragments and whirled around Raon and Mark Gorton.

Hwaaaaaaaak!

The white paper pieces burned black and vanished.

And when they disappeared, Raon and Mark Gorton were no longer in the audience chamber, but in a charred forest.

‘Did we already move?’

He knew the Magic Tower Lord’s magic was mysterious, but not to this extent.

– “It seems she sent you properly.”

Wrath frowned at the blackened ground.

– “I can feel that crazy woman’s mana around here.”

He lowered his gaze, saying Merlin had fought here.

‘You’re right. It’s Merlin’s mana.’

Raon nodded as he examined the scorched trees.

Merlin’s mana was chaotically smeared through the area, as if she’d been attacked the moment she sent the letter.

‘But…’

I don’t know where she is.

About thirty minutes had passed since Merlin sent the letter. She—and whoever was chasing her—could be far from this forest by now.

‘Wrath.’

– “Even this King’s Aura Sense can’t catch her. It seems she’s moved somewhere else entirely.”

Wrath said it was difficult, yet still kept spreading his Aura Sense.

‘Damn it…’

Raon pushed the Ring of Fire and the Glacier to their limits, even drawing on the emotions of the Demon Kings.

Paaaaaa!

Pain twisted through body and soul as he spread his Aura Sense endlessly.

Then, from the far western edge, he heard the faintest sound—air tearing.

– “I found her!”

‘I heard it too!’

Raon and Wrath turned west at the same time.

“It’s west!”

Raon told Mark Gorton to follow and stomped off, smashing the ground as he sprinted toward the west.

“Yes!”

Mark Gorton grit his teeth and chased after Raon, who shot forward like a red beam.

‘I’ll follow you even if I die!’
