The Regressed Son of a Duke is an Assassin Chapter 20

Chapter 20: The Strongest in the Demon Realm (1)


Offspring inheriting the blood of gods and the beings closest to the Creator.

They are noble creatures that are rarely seen in a lifetime, and a race that exudes an overwhelming presence that lowly creatures dare not approach.


All eyes on the ground turned toward the sky.

A violet dragon soaring gracefully through the stormy sky with its large wings fully spread.

Its serpentine body was long enough to wrap around an entire tent, and its four limbs, each equipped with sharp talons as if swords were embedded in them.

A black horn grew on its forehead, sending a chilling sense of dread to those who saw it. Knights, including the emperor and even the duke who had seen many battles at the front, were speechless with their eyes wide open and mouths agape.

“Look here, Willeus! No matter how I see it, that there can only be a dragon… right?”

“Correct. It looks like a young one still growing, but there’s no doubt it’s a Devil Dragon.”

“Are they seen often?”

“How could that be? This is the first time I have personally faced one from inside the outpost.”

Though many demon beasts lived in the Limea Gorge, there weren’t any dragons among them.

It was a rare occurrence for the shadow of a dragon, seen far in the demon realm’s skies, to cross over into the valley.

The Devil Dragon was flying at low altitude, clearly observed, circling around without leaving the area.


The dragon seemed to be in some distress, emitting pained groans, suggesting it was not in a normal state.

As everyone puzzled over the situation, unable to move from their spots, the princess Arin pointed in a direction with a surprisingly clear voice.

“Look over there!”

Everyone’s gaze followed where her finger pointed—near the Devil Dragon’s ankle.

Soon enough, they spotted a familiar figure near the dragon’s right ankle.

Despite the limited visibility due to the storm, something resembling a small child was precariously hanging onto one of the dragon’s feet.


The duke’s focus sharpened when he realized that the one hanging was none other than his son.

“Si, Sian?”

“That… isn’t that your son?”

When the other knights, including the emperor, recognized the figure, their eyes turned to the duke in unison.

“How on earth did he end up there…?”

He was supposed to have led the monsters away alone after ensuring the princess’s safety, yet, somehow, he was leisurely traveling through the turbulent night sky with a dragon.

The situation, inscrutable to all.

Despite the complexity of the matter, the duke quickly shook his head.

This was not the time to inquire about the circumstances.

What appeared before them was a formidable demon beast.

As it was his duty to eliminate all the emerging demons, he would have to kill it, even if it was a dragon.

The duke’s right hand manifested an enormous amount of mana as he resolved his will.

“The sword of my conviction will soar to the heavens!”

Together with the incantation, a blue magic circle was drawn in the sky.

Five radiant swords materialized one by one.

The glimmering blades were all aimed at the Devil Dragon flying in the air.

This is troubling.

Actually, more than troubling—it’s a highly perplexing situation.

Below my suspended feet, over a hundred eyes were fixated upon me.

This is insane.

From the knights of the frontlines and the imperial guards, to the emperor and the duke at the center, to the corner where Emilie huddled, and the princess Arin with a face mixed with laughter and tears—everybody I should not have run into, I had met all at once.

[Hey! Why are you suddenly freezing like a statue? Aren’t we going to catch that thing?]

“I’m going to get caught myself if I try catching it right now!”

Exactly 10 minutes ago.

After dispatching the troll’s corpse at the Blood River, I encountered a dragon, the noblest of beings.

At first, I was a bit confused as to why it showed up here.

For a hefty demon beast from deep within the demon realm to appear in the frontline area was completely out of the ordinary; it could be considered unprecedented.

But that confusion was fleeting. Soon after grasping Ceyram, I charged towards the dragon.

It would be foolish not to seize the blood of a hefty demon beast when it’s right in front of me.

A noble being?

They might be the race closet to the Creators, but not each individual is overwhelmingly strong.

Just as among humans there are strong warriors and weak cowards, not all dragons are mighty just because they are dragons.

Moreover, the dragon I was grappling with was still a maturing individual.

To struggle against a green dragon with no experience was out of the question.

The dragon initially seemed interested when I pounced with courage, but soon after, it took to flight in retreat.

An irresistible prey, I chased it, utilizing even my secret techniques barely holding onto its ankle…

Unfortunately, I ended up coincidentally encountering all these unwelcome individuals.

[What? Were you just standing still because you were worried about those down there?]

“Should I put on a show of hacking and slashing in broad sight?”

[Then what are you planning on doing? Are you just going to keep hovering around like this?]

Having reached as far as manifesting the magic sword and yet unable to end it, Ceyram was infuriated.

Even though I understood his agitation, if I made the dragon crash and ended its life here, I’d be taken straight to the royal capital.

Perhaps it would be better to act as if I’ve been kidnapped by the dragon?

Just as I was pondering this, a familiar blue light flickered far below.

– Wooong

A sophisticated magic circle for casting a high-level spell.

The caster was none other than my father.

Wait, isn’t that spell a bit dangerous?

“The sword of my conviction will soar to the heavens!”

With the incantation, five glowing swords zoomed towards me—or rather, towards the Devil Dragon—at an incredible speed.

An 8-star grade light-attribute spell ‘Heaven’s Sword Rain’.

Knowing that his son was above, was he still unleashing such dangerous magic?

So, a dragon was, after all, a demon beast that needed to be dealt with?

He truly is the authentic guardian of the continent.

Sensing danger, the Devil Dragon agilely turned to evade.

– Thump!

However, the last sword, thrown in an unavoidable trajectory, struck the Devil Dragon’s leg.


With a scream, the Devil Dragon thrashed wildly.


Unable to withstand the aftermath, my grip on the dragon’s ankle slipped away.

Having nothing left to hold onto, I became a mere vagrant in the air.

– Swoosh

In the midst of pain, the Devil Dragon, without a backward glance after seeing me fall, flew off into the distance.

Ah, I let my prey slip right before my eyes…

However, now wasn’t the time to lament over the lost meal.

If I were to continue falling aimlessly, I’d be doomed to greet the reaper of hell.

Although knights below were rushing to catch me as I descended, they were clearly out of reach.

[What are you doing? Do you want to kiss the dirt? Fly already!]

“Do you think you could fly in this situation?”

[Then what? You’re going to die this way? If you fall and die like this, expect to be killed by me twice!]

Would that mean dying three times including my previous life?

It might sound like a joke, but I knew the current situation was severely critical.

Yet, I couldn’t use a secret technique in front of so many watching eyes.

As I closed my eyes briefly in contemplation,

– Kwaah

The sounds of a rushing river below caught my attention, and my eyes snapped open.

Directly underneath the spot where I was falling, a torrent with a crimson gleam.

It was a branch of the Blood River, where I had disposed of the troll’s corpse.

A smile crept onto my face at the sight of the river.

“Is there no simple way of dying after all?”

[Hey, master! What are you thinking right now? Don’t tell me you’re planning on diving down there?]

“It’s time I took a bath, isn’t it? Don’t think too poorly of it!”

[Are you crazy? You’re planning to wash me in that filthy water now?]

Ceyram was erupting like a boiling volcano inside my head, but I ignored it all.

I believed the method churning in my mind was the best course of action available.

To prevent an awkward crash into the ground, I rotated my body several times and aimed for the heart of the Blood River.

– Plop!

Without delay, my small body experienced a dramatic encounter with the icy blood-stained waves.

* * *

– Whoosh

Out of the blue, what appeared to be a young Devil Dragon flew past overhead at great speed.

Watching from the ground, ‘Belcalion’ tilted his head in curiosity.

“Devil Dragon flying over from that direction. Interesting.”

The direction from which the dragon came was the side of Limea Valley.

“It looks somewhat injured. An immature dragon seems to have taken a wrong turn and got hurt quite badly.”

A middle-aged demon added, piquing Belcalion’s interest.

“Hmm, is that so? A bit of arrogance is common among them, but it’s not every day you see dragons fleeing tail between their legs. Is there a formidable demon over there?”

“Well, if that was the case, chances are it wasn’t demons, but humans who did that.”

“Humans? Those creatures weaker than Hellhounds? Rogers, you’ve improved your sense of humor.”

Despite the sarcastic tone, the middle-aged demon remained unfazed.

“If they were weaker than Hellhounds, they wouldn’t have claimed those lands beyond us. Although they start the weakest and most insignificant, in terms of potential for growth, no species can compare to humans.”

“Oh! Rogers, you know more than I expected. Have you actually seen humans?”

“How could I have? I’ve lived here my whole life…”

“Then, making it seem like you know something…”

“I only spoke based on the history of the past.”

Belcalion pouted with deflated enthusiasm.

He turned his gaze away, intending to go on his way, but for some reason, his head kept turning back toward the direction of the gorge.

It was as if he was being drawn by a certain energy.

“Is there something bothering you?”

“No, it’s strange, but I feel a rather mysterious energy emanating from that gorge. As if it’s both unfamiliar and yet familiar.”

The middle-aged demon looked that way as well, but felt nothing.

“I don’t sense anything there…”

“I’m telling you I sense something! Just wait a minute!”

Belcalion continued to stare in the direction of the gorge, regardless of acknowledgment.

Even then, he strangely felt there would be something fun if he went there.

“Rogers, I’ll need to cancel our plans for a bit. Something urgent has come up on my end.”

“No worries, but please, just go and come back peacefully. If something infuriating happens, don’t go smashing everything up. It’d be terribly troublesome for me.”

Knowing that any attempt to dissuade him would be futile, the middle-aged demon merely issued a mild cautionary word.

However, even that seemed to merely flutter past the ears of Belcalion, who was pretending to listen.

His gaze remained fixated on the gorge, and his eyes even began to redden with excitement.

– Flap

Belcalion unfurled his black wings and took to the sky with high altitude.

He left without looking back, seemingly intent on something that had profoundly caught his attention.

“Please don’t cause any trouble… Your Majesty,” the middle-aged demon mumbled as he watched him fly away, hoping for a safe return.
