Dragonslayer’s Class Regression Chapter 183

Chapter 183

[What did you say?]

Arataso said in a dumbfounded voice in response to Zeke’s words.

“Why don’t you want to tell me?”

This was the most unreasonable demand possible.

Zeke was now trying to blackmail the demon tribe to steal their technique.

‘What kind of person is this?’

Throughout his demon life, he had never encountered such a human.

Arataso shouted at Zeke.

[Why should I tell you that! And how could a human even learn the demon tribe’s barrier technique in the first place!]

Zeke chuckled and retorted.

“I’ve learned the Hero King’s swordsmanship, so why couldn’t I learn the demon tribe’s barrier technique?”

Arataso’s voice trembled as he spoke.

[H-Hero King? Don’t lie!]

“It’s true. You’re so suspicious that you can’t even believe a person’s words.”

Arataso muttered to himself, unable to believe it.

[The Hero King’s swordsmanship? Impossible. That can’t be…]

“Stop mumbling to yourself. Are you going to tell me or not? If not, just live sealed in this sword forever.”

Just as Zeke was about to remove his hand from the sword,

Arataso called out urgently.

[Wait a moment!]

Zeke waited with his hand almost, but not quite, leaving the sword.

Arataso spoke with an anxious voice.

[If I teach you the barrier technique, will you let me go?]

“That depends on what you do.”

[You coward! Answer me directly! Will you let me go?!]

Then Zeke reignited the sacred flame.

WHOOSH!

[AAAAARGH!]

“Who’s raising their voice here? I was going to seal you forever, but I’m giving you a chance out of pity.”

As Zeke withdrew the sacred flame, Arataso quickly changed his tone.

[D-damn it. Fine. I’ll teach you the barrier technique. But promise absolutely not to use that damned flame.]

“You mean the sacred flame?”

[Yes, if you swear not to use whatever this sacred flame is, I’ll teach you.]

Zeke hesitated but ultimately accepted Arataso’s conditions.

Arataso spoke with a voice full of irritation.

[Besides, I won’t take responsibility if you can’t learn it.]

“If you teach it poorly, it’s a contract breach. You’ll be sealed along with the sacred flame.”

Arataso gritted his teeth at Zeke’s interference.

‘More demonic than a demon.’

After calming down somewhat, Arataso asked Zeke,

[You already have a strength unusual for a human. Though I can’t believe it, if you’ve truly learned the Hero King’s swordsmanship, what else do you want to learn?]

“I’ll use anything to become stronger.”

[What an unusual human.]

“And before that, you mentioned Aura magic as a demon clan technique. Explain what that means.”

[Just as it sounds. The technique you call Aura was created by stealing our martial arts.]

“Who stole it?”

[How could we know everything done by cunning humans? Perhaps some foolish demon who contracted with humans might have passed it on.]

Magic used by humans was originally passed down by dragons.

On the other hand, the origins of Aura remained unknown to the world.

Zeke, who had obtained the connection, knew that Sethon Draker created the Aura cultivation method to kill dragons, but he didn’t know exactly how it was completed.

‘Sethon Dreaker made a contract with the demon tribe to create the Aura cultivation method?’

It was hard to imagine that he, the heir of Hero King Kaisir and known as a knight of integrity, had made a contract with the demon tribe.

Zeke told Arataso,

“I’ll find out if what you said about Aura originating from the demon tribe is true by learning it.”

Arataso gritted his teeth and began explaining the barrier technique he knew.

[As the first carrier of the ‘Clear Green Wish’ and a user of the greatest power, I could use this strength…]

“Skip the unnecessary talk, get to the point.”

[…I’m increasingly curious if you’re truly human. Anyway… Right. To the main point. The barrier technique I used originated from the martial arts technique ‘????????????????’.]

Because it was in the demon realm’s unique language, it couldn’t be translated.

Zeke asked the system to translate it to the closest feeling.

[Using Chronos language as a proper noun, the term most similar in meaning is ‘strong wave empty vibration’.]

“Strong wave empty vibration.”

After naming the martial arts technique, Zeke told Arataso to continue explaining.

[Establishing territory is crucial in strong wave empty vibration. It’s about building my domain using energy and then extracting the power of enemies who enter that domain.]

“You mean the barrier created by stabbing the sword into the ground?”

[Yes. In the current realm, I’m using a clone since I can’t use my original body, so I had to use a medium to create the barrier. But originally, I would spread the barrier using my own energy.]

“Hmm, I don’t quite understand just by hearing about it.”

[I’m not sure if a human can actually do this. But a promise is a promise, so I’ll teach you.]

Suddenly, the cloud iron sword began to vibrate slightly.

[Remember this vibration.]

“What is this?”

[Creating resonance using vibration to turn your domain into a barrier.]

Zeke carefully observed the slight vibration Arataso created.

‘Is it about colliding mana with mana to create vibration?’

As a heavenly bone-grade being, Zeke could immediately imitate something he had seen once.

He immediately took out Bahamut and tried to generate the vibration created by Arataso.

WOOOONG!

It was a power using mana itself, not elemental power or aura.

As Zeke immediately created the vibration, Arataso was startled.

[Ah, no! How can a human create a strong wave resonance…?]

“Didn’t you think I could? Stop chattering and quickly tell me the next step.”

[Th… the next is……]

Through Arataso’s continued explanation, Zeke learned the magical technique of the demon realm and could understand its principle.

In the material world, natural mana cannot be used directly, so it is converted and used as magical power or aura.

However, the demon race’s method of handling power was completely different.

Just as mana exists in the material world, in the demon realm, the power of authority created by each constellation exists in each domain, and the retainers could use that power.

The stronger the constellation’s power, the wider the domain’s range, and the higher the power density.

Arataso’s master, the ‘Clear Green Wish’, was a strong demon ranking within the top 50, so it was said to have a considerably wide domain.

He could hear more stories about the demon realm unrelated to boundary techniques because retainers could only use the power of the constellation they serve, making betrayal impossible.

However, there was one exception, and that was the constellation battle.

If defeated in a demon-to-demon constellation battle and the ownership of retainers and domain is taken away, it becomes possible to become a retainer by receiving the power of that new constellation.

Since demons’ power comes from strong retainers and domains, this constellation battle played a crucial role in raising their rank.

Zeke, who was listening to the explanation, asked Arataso:

“Then why do demons or demon races contract to take human souls?”

[Human souls are an excellent material for strengthening forces. They can enhance the power of retainers and expand the constellation’s domain.]

“Do human souls have such power?”

[The souls of all living beings with free will contain strong energy. We prefer humans because among all races, humans have the strongest desires. If there’s desire, it becomes easy to specify the contract’s price.]

Zeke nodded at Arataso’s words.

Just as he said, no race was as vulnerable to temptation as humans.

“Wait, if the retainers receive power from the constellation as you say, what is magical energy?”

[It is a tainted power. It’s an unholy power created by souls that have completely fallen, lost their reason, and dropped into the abyss.]

“I didn’t know demons thought of magical energy that way.”

[It’s a low-level power used by lower-ranked demon races or demon beasts lacking reason. High-ranking demon races like me don’t even look at it.]

“The Herald’s of blood and madness use very rough and negative power. Is that a different power from magical energy?”

[Those barbarians are disgusting to even think about. Most of the constellations once worshipped by orcs used such barbaric power. They are strong, but the power itself is rough and quickly taints the user with madness.]

Arataso’s voice seemed to tremble with distaste.

‘Seems like demons in the demon realm also have various types of power.’

After that, while listening to various stories, Zeke learned the magical technique from Arataso. Fortunately, the technique could be applied using mana, so it wasn’t difficult for Zeke to learn.

Zeke created waves by vibrating mana according to the strong wave resonance Arataso taught him.

WOOOOOONG!

The resonance Zeke created gradually expanded its wave range. But at some point, the wave’s power began to fade.

“WHEW!”

Zeke, who stopped the resonance, was breathing heavily.

“It’s not as easy to endure as I thought.”

The magical technique of the demon realm was a technique using the power of the domain.

Arataso explained that because the mana in the material world has lower density than domain power, creating and maintaining resonance itself is not easy.

Zeke wanted to apply this strong wave resonance to Fab’s infinite chain formation.

If he could activate the infinite chain formation that restricts the opponent’s movement and continuously attack within it, he could potentially defeat many enemies with minimal damage.

Unlike the disappointed Zeke, Arataso was amazed by the resonance Zeke created.

[Huh, a human actually succeeded in strong wave resonance. Surprising.]

“Do all demon races know this magical technique?”

Then Arataso shouted loudly.

[What nonsense! Demons who can properly execute strong wave resonance can be counted on one hand, including me. Maybe the two-attribute demon race might know. Fundamentally, this resonance isn’t something easily learned.]

“But learning it, I found that strong wave resonance and aura cultivation techniques are completely different in principle.”

Arataso clicked his tongue and said:

[The technique you call aura is extremely trivial to us demon races. For high-ranking demons like me, typifying power is as easy as breathing. But humans can’t even do that properly, barely accumulating mana in their body and then barely typifying it on weapons. It’s proof of being an inherently inferior race.]

“You’re quite talkative for someone sealed by such a human.”

[Ahem.]

Zeke created a weak resonance and said to Arataso.

“Anyway, you mean this strong wave resonance is a technique superior to aura, right?”

[That’s right. Resonance can’t be created just by accumulating power. Ignorant fools like the blood and madness corps would never be able to use it even if they died and came back to life.]

Because it was the language of the demon race, it was impossible to know how much of it was true, but it was undoubtedly a technique from a new perspective.

Zeke said to Arataso.

“You did quite well, so I’ll give you a reward. Besides not using the sacred flame, is there anything else you want?”

[Let me go with honor.]

“That’s not possible.”

[Creak. Then don’t lock me up in that strange subspace, but leave the sword outside. Let me at least look around the current world.]

“Okay, I can do that much. It might be difficult to always leave it out, but I’ll let you take a look often.”

Zeke readily accepted and entered training.

It was during his training in the castle’s training room, practicing strong wave resonance and infinite circular connection, that Decker came to find Zeke.

“My lord. A message has come from the Four Seasons Castle.”

“Decker, I told you not to call me ‘my lord’ and call me as usual.”

“Honorifics create rank.”

Knowing Decker’s stubbornness, Zeke shook his head and let it go.

“Why suddenly from the Four Seasons Castle?”

“They want to assign a specific mission.”

“A specific mission?”

Specific missions were usually given to experienced knights.

This was because specific missions were mostly difficult and high-level.

Zeke hesitated and then stood up.

“I don’t know what it is, but I’ll go to the Four Seasons Castle first.”

“Should I prepare a carriage?”

“No, forget it. I’ll go alone.”

Since the Nostra Family might attack at any time, it was better to move secretly alone.

Zeke entrusted Zion, who was in the underground prison, to Decker and immediately prepared to go out.

It seemed the safest to keep him here until Arina returned from her mission.

The next day, Zeke rode Bucephalus and ran to Atlas in one breath. Using a portal would have been convenient, but he deliberately avoided it to avoid drawing attention.

While a normal horse would have taken about fifteen days at best, riding Bucephalus took only about two days.

Zeke entered the Four Seasons Castle right away.

When he tried to receive the specific mission from the assignment department, he was told an unexpected story.

“Are you saying the lord himself designated this mission?”

The clerk nodded.

“Yes. He said to send you directly to the lord’s office when you arrive.”

If the lord was directly designating the mission, it didn’t seem like an ordinary mission.

Zeke, feeling puzzled, went up to the lord’s office.

As he entered, Lord Arthur Draker welcomed him warmly.

“Zeke, you’re here. I was just talking about you. Sit here.”

There were already people Zeke knew sitting in the lord’s office.
