Episode 43. The Expert (3)
Coatl Zaire—a Calamity-grade Demonic Beast counted among the most fearsome in the Amazon, Oedae Demon Realm.
With a body length reaching tens of meters, it possessed a sheer, overwhelming scale akin to the manifestations of Jörmungandr or Ouroboros, the serpents spoken of as heralds of apocalypse.
Its scales, a blend of black and lapis lazuli, shimmered with violet luster whenever they caught sunlight.
The head, crowned with a cobra’s flared hood, bore no eyes.
Instead, it bore an otherworldly visage—glowing red script that could not be deciphered by any knowledge modern civilization possessed, etched into its very flesh.
A calamity the Association ranked as the gravest threat, warranting humanity’s closest vigilance.
Though eyeless, its sensory perception across its entire body was extraordinary—gauged by data compiled from the lives of countless Hunters, it left no blind spot in detecting intruders.
Whoooosh—!
Seizing the moment when a sudden downpour began to drench the land in torrential rain, Jeong Hyun-su slipped naturally into Coatl Zaire’s lair.
For Seon-u Yong-nam watching from afar, it felt less like observing someone who knew what they were doing than witnessing a man simply step into the jaws of death to avoid getting wet.
‘A weary one,’ Seon-u Yong-nam thought.
Seon-u Yong-nam had to weigh his decisions solely by the Association’s interests.
The Garam Guild showed no loyalty to the Association, and now Hanul was joining them—clearly something was afoot.
Yet here was an SSS-rank achiever from such a place, suddenly showing interest in the Association.
He needed to observe whether Jeong Hyun-su was worth exploiting, so he simply watched the man enter this South American calamity den.
It was no real combat situation—extracting Jeong Hyun-su would be well within his capabilities.
Thus, riding the squall as planned, Jeong Hyun-su entered Coatl Zaire’s lair.
He descended using the moss-laden vines that clung to the upper reaches of the den.
The downpour drowned out sound, and the surge of magical energy created by the mana-infused rain easily swallowed any presence as minor as Jeong Hyun-su’s current state.
Croak! Croak!
Chirp! Chirp!
The cries of insects and frogs dwelling in the lair echoed raucously.
Jeong Hyun-su wove his magical aura into the midst of it all.
To hide from the sensory perception of a Demonic Beast that could detect vibrations from great distances.
Splat!
Jeong Hyun-su burst open a large venomous toad he’d caught on the way in, coating his entire body in its slime.
He borrowed the repellent scent that survival had taught him snakes avoided, masking himself temporarily.
Then he ruptured the rotted seed pods strewn across the nest floor.
‘It’s been a long time since that stench,’ he thought.
Charitably called fermented, it was more accurately the stink of decay—a foul odor that would offend any normal sensibility.
All methods earned through groveling at the bottom of the food chain for survival.
Fighting Coatl Zaire, slaying it, required none of this—
But imprinting himself as a negligible, unremarkable presence before an absolute apex predator at the pinnacle of the food chain was worth the effort.
The rot-stench of these seed pods matched the scent of Coatl Zaire’s shed membrane piled everywhere nearby.
‘I wonder if that madman is still alive somewhere.’
The crazed fugitive who wanted to possess a dragon came to mind—and thanks to him, Jeong Hyun-su had learned survival techniques in this jungle with almost unnatural precision.
In any case.
Carrying the reek of serpent membrane, Jeong Hyun-su infiltrated the heap of dead eggs before him.
The power of a Demonic Beast like Coatl Zaire was boundless, and naturally, its offspring rarely hatched easily.
— Maybe one in a million?
That was what the snake-obsessed fugitive had said about a jungle full of carp and serpents.
In any case.
Jeong Hyun-su burrowed deep into the center of the egg mass, excavating hollow space within the stacked layers and curling his body inside.
Then he activated Hyeoncheongwi-wonggong.
‘Perfect.’
Now, with the time remaining, he could use Hyeoncheongwi-wonggong to erase his presence entirely while concentrating on raising his proficiency—an ideal opportunity.
Rumble, rumble, rumble!
A loud commotion echoed through the nest. There was a time, back when he knew nothing, when such a sound would have terrified him, but now his heart had no reason to clench.
How many times had it been now? The tenth, perhaps?
From that point on, his heartbeat had been nothing but calm—a memory from those early days. Now, with Hyeoncheongwi-wonggong at his command, what was there to fear?
Coatl Zaire flicked its forked tongue, inspecting each egg one by one.
Not searching for an intruder—but seeking eggs still viable, those harboring the potential to hatch.
Yet, as though nothing had changed this time either, the creature examined the eggs and turned its head away without hesitation.
Splash, splash, splash!
A sound of something pouring forth—not excretion, but parturition.
Coatl Zaire laying eggs it had been carrying.
Jeong Hyun-su suddenly recalled words the snake-obsessed criminal had once uttered.
— I wonder who her husband is?
A fragment of memory from the past.
* * *
Through the next day, Jeong Hyun-su devoted himself entirely to the Hyeoncheongwi-wonggong.
His presence, which erased even his own magical aura, kept him hidden even beside Coatl Zaire’s vast body as it cradled hundreds, thousands of eggs.
‘The Hyeoncheongwi-wonggong has reached the ninth tier.’
By fixing his concentration on that single pursuit without arrogance, maintaining density of focus through the entire night, his mastery had advanced.
Then a magic circle traced itself beneath Jeong Hyun-su, and the world shifted.
Inside a wooden building overlooking the Amazon rainforest stretching beyond the horizon stood Seon-u Yong-nam, eyes fixed on him.
“Good morning,” Jeong Hyun-su said.
Seon-u Yong-nam’s lips twitched.
He had much to say.
What he’d expected was to see a hothouse flower raised in Seoul break and despair when thrown into the Amazon—the Oedae Demon Realm—
driven to the brink through a night of relentless assault by demonic beasts and criminals, his true nature laid bare.
Instead, Jeong Hyun-su had slipped into Coatl Zaire’s nest, evaded detection, passed the night unmolested, and returned—bearing nothing but the viscous slime coating his body. There was scarcely a trace of hardship on him otherwise.
‘This one especially… is he specialized in concealment?’
His stealth ability deserved note—a skill that Seon-u Yong-nam himself would have missed had he not known the location from the start.
To trust that ability and enter Coatl Zaire’s nest on such faith showed admirable audacity.
“How did you even find the nest? How did you know it belonged to Coatl Zaire?”
“I simply wandered in while searching for shelter.”
His answer came with unwavering calm, leaving no seam to exploit. Yet Seon-u Yong-nam felt something off.
“Your response was far too composed for that story.”
“I trusted that the Association would send rescue within a day.”
His words flowed with perfect ease.
“So you survived on your skill alone?”
“Yes.”
Had he such faith in the unique inherited technique the Garam Guild was said to possess?
“Fortune favored me.”
Seon-u Yong-nam could not witness the process he’d hoped to see, but neither could he ignore the Association’s reputation.
“I’ll honor my word. From today, you are an Apprentice Knight of the Association.”
Though famous as the inner circle of Seon-u Hyeon, who commanded Battle Mages, the Association’s Knights were not composed of mages alone.
“I’ll give you your first order, Apprentice.”
“Yes.”
“Show me your skill. Eliminate this criminal here.”
Seon-u Yong-nam threw a Wanted Poster at Jeong Hyun-su.
[Name: Jeon Jeong-guk]
[Grade: Blue]
Though his current grade was Blue, he was scheduled for promotion to Red-grade soon.
It was a harsh task to assign an Apprentice.
“I saw you capture a Blue-grader. Prove yourself. You had no intention of receiving formal Association training from the start anyway, did you? If you demonstrate competence, I’ll back you without reservation. And don’t worry—I’m not sending you alone. I’ll assign professionals to work with you. Just pull your weight.”
Jeong Hyun-su nodded at Seon-u Yong-nam’s words.
“Yes.”
“Welcome to the Association Knights. You’re dismissed.”
Jeong Hyun-su’s brief Amazon expedition concluded, and he returned.
* * *
The moment he arrived, Jeong Chul summoned him, and Jeong Hyun-su recounted everything honestly.
“You spent an entire night in an Amazon monster’s nest like that?”
Growwwl!
Haengbok-i was unusually hostile. It made sense—Coatl Zaire’s scent still clung to Jeong Hyun-su.
Whoosh!
Once Jeong Hyun-su wiped it clean with magic, Haengbok-i panted and laughed.
‘You ought to see things through properly, too.’
Haengbok-i’s true identity was the legendary Spirit Beast, the Haetae.
Why it took the form of a small dog, he didn’t know, but the image of it forced into Awakening on the day Garam fell, fighting to protect its family, remained vivid in his memory.
“Eat.”
Jeong Hyun-su fed Haengbok-i strips of premium beef jerky he’d prepared beforehand.
The creature’s Awakening would need to unfold slowly and flawlessly.
‘Should I feed it Nine-tailed Fox meat? Or would Duwuksini work better?’
It was a future discovery that mythological creatures of specific nations required the mythological beasts of that same nation as sustenance.
As Jeong Hyun-su pondered the materials for Awakening, he received a text message.
“I need to step out briefly.”
His departure was for one purpose alone: to meet Kim Chun-sik.
“It’s been a while.”
“A while? It’s only been a few days.”
Kim Chun-sik smacked his lips as he looked at Jeong Hyun-su.
He was going out of his mind over the information concerning the Royal Artifact that Edward Farrington had stolen.
He’d agreed to hear out Jeong Hyun-su’s request in exchange, but the man had nullified the terms by abruptly handling the matter related to the Tyrant King himself.
He’d tried to make contact since, but Jeong Hyun-su’s movements had been too extraordinary—participating in the exchange tournament, severing Park Young-su’s arm, then vanishing with Seon-u Yong-nam, an Association executive.
The faces gathered nearby were far too luminous.
“…I haven’t been able to sleep at night.”
“Is it because of the commotion in Britain?”
“SIS agents are already here. If this turns out to be false, I’m dead…!”
“Don’t be so melodramatic. You found Farrington when those agents couldn’t—they’ll never kill you, chief.”
Jeong Hyun-su’s composure was absolute. Complaints clearly had no effect on him either; who would ever believe he was nineteen?
“Please, I’m begging you to take on this request.”
“I was planning to anyway. Once you complete this, I’ll find the Royal Artifact and hand it over to you.”
“…Really?”
Kim Chun-sik’s eyes flashed with light, then dimmed.
To say he’d find and deliver the artifact himself meant he intended to do it personally.
“Don’t worry. I’ll make sure to mention the name of the Bloodline and you, Chief Kim Chun-sik, to the king.”
Though it was a constitutional monarchy, Britain was a barbarous nation where the king had awakened as an SSS-rank Hunter and suddenly consolidated absolute rule, reviving the caste system.
However, since the king’s Awakening-related skill had made nearby nobles into powerful Hunters as well, making it a strictly merit-based caste nation, Kim Chun-sik was eager to accept any dealings with the mighty Britain.
“Thank you! So what am I supposed to do…?”
“Surveillance of one person—track their movements and get me real-time location information whenever I ask for it. That’s all. Easy, right?”
Easy in words, but the matter concerned the sheath Avalon of the Holy Sword Excalibur, which the British king was searching for with fierce intensity.
Given stakes like that, Kim Chun-sik doubted whether this was truly a simple task—but he couldn’t refuse.
A request involving a Holy Sword.
“I will complete it without fail!”
“Her name is Jeong Su-jin. She’s a mage. Her position is Senior Magical Engineer Researcher at the World Magic Tower.”
“Yes…?”
“Want me to repeat that?”
“Ah, no—how could I not know Jeong Su-jin?”
A disciple of Association Chairman Seon-u Hyeon and spoken of as the next Grand Mage; a pure-type prodigy.
Jeong Su-jin was an unparalleled mage of genius—believed capable of breaking every record relating to the Tower if she weren’t so devoted solely to magical research.
