Chapter 126
“Become the head of the family? Have you lost your mind, Saya!”
As expected, Baren cried out in shock.
“Your body won’t be able to endure it! It’s far too soon!”
“I’ll be fine. I can do this.”
Saya shook her head with unwavering resolve.
Of course, Saya understood. Inheriting Aconia’s secret art was fundamentally different from learning magic in the ordinary way.
It was the process of channeling a lethal venom, matured within the bodies of every past head of the family, into one’s own Mana Core. Without proper preparation, the body would face unbearable agony and the threat of death.
“Even if you throw yourself into that battle outside, you’ll only meet a dog’s death. And your opponent is the bloodline of Maelern, the enemy of your mother! Why would you stake your life on this!”
Baren gripped the iron bars, trying to dissuade her, but she shook her head.
“I despise Maelern too.”
“….”
“I hate them enough to chew them to pieces. I truly loathe them. But…”
Saya’s gaze pierced through the iron bars toward the bronze-skinned man who continued to stand firm despite the relentless blows from Spider Mask.
“As a mage, how could I simply stand by and watch that fool throw away his life to help us?”
“…Saya.”
“Right now, that idiot isn’t fighting as the heir to Maelern. He stands there simply as one mage. Then I too must aid him as a fellow mage.”
Baren’s expression grew heavy with conflicting emotions.
He saw the resolute determination burning in his daughter’s eyes—the same fierce light he had once carried as a proud head of Aconia.
That brilliance, lost to him long ago beneath the weight of fear, now blazed from his daughter.
And so, he had no choice but to make his decision.
“…Saya Nafelus Aconia. Do you harbor any regret in this resolve?”
Baren spoke in a low, solemn voice.
No longer the voice of a father worried for his daughter—Baren now addressed her as the current head of Aconia, calling upon his successor.
When Saya nodded, Baren continued.
“Extend your hand.”
“Yes.”
Saya thrust her hand through the gap in the iron bars.
Baren positioned his thumb above her palm. Soon, a transparent liquid secreted from his Mana Core flowed down his thumb, gathering in droplets upon Saya’s palm.
“Accept it. You must not resist. The poison will destroy your body.”
“…I understand.”
There was only one reason Aconia’s secret art adhered to the principle of single-line succession.
It was because the ultimate venom, passed through the bodies of every past head and matured over more than a century, was transmitted this way.
Its name: Extinction Venom.
Just as poison sealed in a jar grows more potent with time, Extinction Venom had used the Mana Cores of successive Aconia heads as vessels, cultivating its toxicity across generations.
Now, after more than a hundred years, it had evolved into a poison so terrifying that nothing else on the Continent could compare.
The past heads of Aconia had endured the agony of their own bodies being consumed, nurturing this single drop of venom for one purpose: to annihilate those abhorrent enemies of Maelern when war inevitably came.
Yet now Saya accepted Extinction Venom—not as a hidden blade to pierce Maelern, but to aid one who stood with Maelern.
A sharp hiss.
As Extinction Venom pierced her skin and seeped inward, a searing heat engulfed her entire body, burning through every mana pathway.
Even Saya, the heir who had built up tolerance by consuming countless poisons throughout her life, found the overwhelming toxicity nearly unbearable. Black-tinged blood burst from her lips.
Yet Saya swallowed her scream and focused every ounce of her consciousness. She carefully wrapped a single drop of the raging Melthan with her own mana, guided it to the deepest reaches of her Mana Core, and sealed it firmly away.
With that, the succession ceremony was complete.
“Saya, with this… from now on, you are the family head who will lead Aconia.”
“…Yes.”
Saya rose unsteadily to her feet, adjusted her sleeves, and made her way toward the Passageway of the Cave.
Watching her retreating figure, Baren let out a sigh.
“The Melthan has grown so formidable through bloodline inheritance, yet the hatred between families… perhaps it too dilutes as it passes through the blood.”

Spider, the leader of the Beast Face Society, felt that the current situation was unfolding in a most troublesome manner.
‘How tenacious.’
Rashek el Maelern, the bronze-skinned man, was merely a mid-tier 5th Rank warrior. Before Spider, a top-tier 6th Rank Mage, he should have long since become nothing but meat.
Yet Rashek showed no signs of falling. With one leg broken and limping, he still forced the power of spirits to his aid and stubbornly endured. Blood poured like rain from the hole in his shoulder blade, yet his fists extended without the slightest hesitation.
Pathetic.
His foolish and stupid persistence was enough to make her scoff.
“…Really, I can’t stand guys like you.”
Spider frowned and extended her tentacles long, aiming at Rashek.
Whoosh!
In that instant, a violet spike flew in from Spider’s blind spot.
Clang! Spider swung one tentacle to deflect the spike. But the tentacle that touched it rotted away in an instant.
In other words…
“…Poison.”
As Spider sighed and turned her gaze, the woman of Aconia stood with her fingertips aimed forward.
Spider’s expression turned vicious.
“…A mere poison user dares challenge me.”
The fact that someone of merely 4th Rank had interfered was deeply displeasing.
“Fine. If you want to die that badly, I’ll kill you together.”
Once she obtained Aconia’s secrets, that would be enough. It would be better to eliminate these useless burdens all at once.
Spider drew forth more tentacles from her back. Her control over the chimeras within the cavern would weaken somewhat, but if she ended this swiftly and then focused there, it would suffice.
Boom-boom-boom-boom-boom!
The tentacles surrounded all sides and surged toward Rashek and Saya.
The two struggled to deflect and evade the tentacles, but their limit was clear.
The tentacles broke, were severed, rotted away, and regrew, while their bodies could not.
By the time the cavern floor was slick with the blood Rashek had shed, he finally threw his last gambit.
Abandoning all defense, he charged in a straight line.
“Hmph.”
Spider smiled with satisfaction.
‘…Pathetic.’
This was actually welcome. The chimera factor grafted onto Spider’s back was specialized in defense rather than offense. Such a crude attack would never work. She would simply deflect it and pierce his heart in one stroke—the end.
That was what she thought, and that was what happened. Rashek’s both fists were deflected by the tentacles. At last, Spider’s remaining tentacle was about to pierce his defenseless chest when—
Whoosh.
The Aconia Mage slipped her fingers into her sleeve and withdrew them, extending her index and middle fingers straight toward Spider.
A trivial gesture that barely registered even a ripple of mana.
Spider ignored it. Whatever venom this woman unleashed, her tentacles could easily block it.
But that was her fatal mistake.
“….”
The Aconia Mage flicked her fingertips once, lightly.
In the next instant.
All the tentacles writhing behind Spider’s back froze in mid-air. Her consciousness ceased entirely at that very moment.
There was no warning, no delay.
Spider died without even realizing she had been poisoned.
“…Huh?”
Rashek el Maelern, who had braced himself for death, wore a bewildered expression.
Spider stood dead on her feet.
The Black Mage, who possessed power at the pinnacle of the 6th Rank—Archmage-class strength—had met a death far too hollow.
This was Extinction Venom.
A lethal poison that granted a quiet death like slipping into sleep the moment it took hold.
Saya gazed at her own fingertips and let out a hollow laugh.
“I… Miss Saya, I apologize.”
Rashek el Maelern offered his apology first.

[KYAAAAAAAGH!]
With the Chimera Sorcerers eliminated en masse, the uncontrolled chimera forces completely collapsed.
Panic-stricken chimeras rushed toward the small passageway in the corridor, trampling over one another.
There was only one passageway, yet dozens of massive chimeras.
Many were crushed to death as they fought to squeeze through.
“…I suppose it’s over.”
I steadied my ragged breathing and surveyed my surroundings.
Thanks to Renia’s rune magic support and my own fierce combat, more than half of the hundred-odd chimeras that had filled the cave lay slaughtered.
The Chimera Sorcerers of the Beast Face Society, save for one Fox Mask, were all corpses scattered across the ground.
“H-help! Don’t come near! I don’t want to die!”
The sole surviving Fox Mask screamed at me and tried to crawl away, but a pale blue mana blade was still firmly embedded in his thigh.
“Don’t worry. Why would I kill you? I have questions for you first.”
I wiped the blood from my sword and approached Fox Mask.
“Fox, I want to ask you about that elixir I saw at the Red Pirate Guild.”
“An… elixir?”
“Yes. That elixir that forcibly twists one’s vital essence to elevate their realm. I encountered a mage in a similar state long ago.”
My suspicion pointed to none other than House Rucen.
Petra, whom I had faced during last year’s Council meeting—her Mana Core had been grotesquely twisted just like the Captives of the Red Pirate Guild.
I had to confirm whether there was some connection between the Beast Face Society and House Rucen.
“I, I… regarding the antidote…”
Fox’s pale lips trembled as he struggled to speak, but the moment never came.
“Reagan…!”
Renia’s urgent cry echoed through the cave. Before I could even hear the rest of her words, I sensed movement from above and had already leaped backward.
Crash!
A massive black form plummeted directly where I had been standing moments before.
Unfortunately, Fox, who had been standing just below, was crushed into a pulp beneath the black mass. But I had no time to mourn him.
“…A chimera?”
I stared at the monstrosity looming in the settling dust, my expression darkening.
It was certainly a chimera born from synthesis, but at this point, it transcended what could be called a chimera.
A body so grotesquely bloated it consumed half the cavern. As if wearing an inverted mountain, a shimmering veil of cyan mana rippled ceaselessly through the gaps between peeling, oozing flesh.
“What in the world have those Beast Face Society bastards created?”
It was in an entirely different weight class from any chimera I had faced before. In fact, across my entire previous life, I had never encountered anything this vile.
The Beast Face Society must have crafted this as their trump card.
Then why had this chimera broken free from its sorcerer’s control and crushed Fox?
The answer came soon enough.
“Could it be… the Mage controlling this chimera is dead?”
If that were the case…
“Did Rashek el Maelern do this?”
If Rashek el Maelern had killed the Chimera Sorcerer, and the chimera, now freed from control, had begun acting on pure instinct, that would explain everything.
Regardless of the reason, what mattered now was eliminating this abomination.
But there was one problem.
“…I can’t see it.”
Even with my naked eye, I couldn’t locate the chimera’s heart, which should have been within its body.
The thick layers of skin and fat were entirely composed of murky mana, completely obscuring my vision.
To make matters worse, I could no longer maintain the “Sight” through my cloak. I wiped away the nosebleed trickling down my upper lip and stuffed the cloak into Andvari’s Cube.
What I needed to do now was clear.
‘I need to strip away its shell.’
I shouted toward Renia behind me.
“Renia, I’ll draw its attention however I can. You scrape away as much of that monster’s outer shell as possible!”
“Y-yes!”
Renia seemed startled by the creature’s immense size, but she quickly nodded and deployed her Rune magic.
Instead of Benheim’s greatsword, I gripped two mana blades forged through Temporary Blade magic in each hand.
With an exterior this thick, magic alone would struggle to carve through it. A brute-force dismantling with two blades would be far more efficient.
Crash!
The monstrosity raised its foreleg and charged. I threw myself aside, and the cavern wall collapsed entirely in its wake.
Devastating destructive power. If it so much as grazed me, I would be reduced to pulp like that fox.
[Roooar!]
The chimera twisted its massive body and descended upon me again. I lowered my stance and crossed my mana blades to block its claws.
Screech!
My palms screamed as if they might tear, but I managed to flick away the creature’s claws and shatter its stance.
Its chest lay exposed. A beam of light lanced out, tearing through its flesh.
It was Renia’s rune magic. While the abomination reeled from the impact, I burrowed deeper into its body and wielded my mana blade with frenzied desperation.
The process resembled butchery. Carving through thick outer hide, tearing through resilient inner layers, pulverizing the grotesque flesh writhing within.
The creature thrashed in agony and tried to shake me off repeatedly, but I was no novice to be undone by such straightforward, honest attacks.
[Crunch!]
Finally, when I drove both mana blades deep into its thick layer of fat—
The abomination twisted its massive body, attempting to crush me beneath its weight. I tried to pull the blades free, but regenerated flesh had already clamped down on them. I had no choice but to release my grip and roll backward.
Boom! A shockwave powerful enough to lift my body off the ground swept through the area.
“Reagan! Are you all right!?”
Renia cried out in alarm as I was helplessly driven backward by the shockwave. I wiped the blood trickling from my lips with the back of my hand and nodded.
“I’m fine. This is manageable. Just a bit longer and we’ll have it.”
“…Just a bit?”
“Probably.”
Thanks to Renia’s covering fire and my relentless assault, the thick shell that had encased the creature in layers was already tattered and torn.
No more veils obscured my vision. Now I could see clearly through to its left chest, where a heart pulsed in the depths.
“…Renia, buy me some time.”
“Got it!”
I rotated my Mana Core and drew out every last drop of mana remaining within me.
Upon the long spear blade forged through blade magic, I inscribed the rune letters Kenaz, Tiwaz, and Uruz. Then I layered the three-color spectrum combination of red, yellow, and white through prismatic magic—apricot.
I grasped the apricot-hued spear. The very same weapon I had wielded when I targeted the blood mage Markel’s life.
The target was, of course, its heart.
As I took my stance, the abomination sensed the danger.
[Kieeeek!]
The creature rushed at me desperately, raking its claws, but they bounced off the protective barrier Renia had conjured with Algiz.
Yet even Renia’s magic could not fully withstand the creature’s tremendous mass—the shield shattered after blocking just one assault. Renia staggered and retched.
But it was enough.
A single moment was all I needed.
Whoosh!
With all my strength, I hurled the apricot spear toward the creature’s heart.
Light flooded the cavern.
Exhaustion brought vertigo. Renia caught my swaying form and steadied me.
When the dust and brilliance finally cleared and my vision returned—
The abomination stood motionless, a gaping hole large enough for a person to walk through torn clean through its chest.
[….]
The creature collapsed without even a final cry, dissolving into formless ruin.
“…Wow.”
Renia let out a small gasp of awe.
For a moment, Renia stared at the melting chimera corpse, then turned her gaze toward me.
“Reagan.”
I lifted my head, wondering if she was perhaps replaying the recent battle in her mind, but her expression was far from ordinary.
“About earlier.”
“Earlier?”
“Yeah. When we first entered this cave. What did Reagan say to me back then?”
I searched my memory.
Certainly….
“…Whether the pay was good?”
“Right. That. The pay. You were talking about mercenary work?”
“I… suppose so?”
“The fact that he suddenly said something like that while looking at me means you must have had similar experiences back when you were a mercenary, right?”
….
Renia laughed.
But her smile did not spring from joy. Beneath it lay a current of displeasure.
“Didn’t Reagan promise to choose me instead of that girl?”
I was cornered.
