Chapter 162: When The Self Insert Meets A Main Character!!

"So that’s the king, aye?"

Adam spoke softly, arms folded as he watched on. Within his energy sphere, he floated upside down, slowly spinning in place.

The energy inside was in a slime like state, glowing brightly, and soft to move in.

This strange race possessed the uncanny natural ability called Water Affinity, it was a power so absurdly powerful and weird that it allowed them to transform the very fabric of existence around them into a liquid state.

Reality itself could be softened, made to flow, ripple, and bend under their will.

For example, if one of these tiny abominations wanted to warp space, they wouldn’t need portals or spells.

They would simply turn space into water, and swim through the joints between dimensions like diving into a current.

But putting that aside, using the power of Water Affinity, he placed his hands forward. Space in front of him began to fold and bend, forming a series of lens-like layers. Through them, Adam zoomed in on the area where the approaching king was located.

Just like a camera tightening its focus, the image came into sharp clarity; three figures stood at the center of the approaching energy.

Two women and one man. And not a single one of them shared the same race.

To the left of the man stood a towering, fish-like woman, easily 6’6".

Her skin shimmered in bluish-purple hues, and her body was a mass of writhing tentacles, all emerging from a black hole positioned squarely between her breasts, clearly the center of her existence.

Her glowing orange eyes burned beneath pink sclera, and her lower half trailed into the form of long, slick appendages that slithered across the tiled pew like curious serpents.

On the right however.... Stood a tall woman with clear skin, a curvy and luscious figure, and a pair of thick, demonic horns curving back from her forehead. Her eyes glowed an ominous red, unmistakably inhuman.

She held a massive staff in one hand, and her long, jet-black hair flowed like ink down her back.

Behind her, two prehensile black tails curled and shifted with eerie precision, flanked by a broad pair of devilish wings on her lower back, sleek, leathery, and regal.

After acquiring demonic energy manipulation from the Demonic Orcs during his run-in with their secluded tribe, Adam instantly recognized what she was: a Succubus, yet not a succubus.

But her Demonic Energy would dictate that she was a high-ranking one at that.

A halfbreed, Adam could also sense Monster Energy just like the Demonic Orcs from this woman.

She wore a simple yet stunning black and crimson dress that shimmered slightly in the warped light. Judging by the sheer density of Monster Energy pouring off her and the others, Adam knew what he was looking at.

All three of them were Peak A-Rank, that woman being more half demon and monster after a closer look, but each was standing right at the edge of Shinso Perfection.

The Emperor Class Stage, or Peak A-Rank, was a terrifying plateau. A stage where power was simply not still, rather it grew endlessly. A-Rank monsters didn’t hit a ceiling.

They kept evolving without pause, their potential unbound. But compared to the perfected state of a Shinso, where beings possessed infinite Monster Energy, never tired, and each bore their own twisted brand of immortality, even Peak A-Ranks were just flawed titans grasping toward godhood.

Monster where being that thrive on evolution more than any other race, even if they too had a Shinso state they can reach.

Monsters Shinso’s where just different in the overall uniqueness upon reaching said evolution.

And then there was the king.

A tiny, doll-sized man with clear skin, unnervingly pristine. Thick clouds of black miasma swirled around his body in liquid form, obscuring his chest and groin. Hovering just above his head was a floating crown, forged entirely from his own condensed Monster Energy.

It reminded Adam of his own fairy transformation, though this version was far more grotesque and refined.

As the crown was blue and and green.

And unlike the others, who floated in violet corruption spheres, the king hovered inside a dense sphere of black and purple energy, like a collapsed star barely holding itself together.

He had short, pale blue hair and thunderous glowing blue eyes. His face wore an expression of absolute boredom, as if he had already seen everything existence had to offer.

But none of that was the shocking part.

No, the real surprise came from Adam’s system, which spoke just then in a rare, shaken tone.

『Master, I sense the powerful aura of a Harem-Type Main Character like yourself』

And at that very moment, the king turn his head, and as if seeing right through Adam disguise, he met eye with his own through the lens.

The two looked at each other, and at this very moment her smiled and said.

"I found you."

Without warning, a massive ball of Monster Energy surged to life in the tentacle woman’s palms.

Before Adam could even react, she launched it straight at him, no hesitation, no concern for the crowd.

The projectile screamed through the air and hit with earth-shattering force. The moment it landed, a shockwave tore outward, the blast strong enough to obliterate an entire mountain range.

Red energy flooded in every direction, only stopped by the King’s barriers protecting the castle arena. With nowhere else to go, the raging energy shot upward, erupting into a pillar of light that pierced through the clouds of the monster world.

The ground trembled. Any chance Adam had at a quiet, clean takedown had just gone straight out the window.

One week earlier

[Notice!! My Lord, this one detects an intruder within the castle perimeter]

The mechanical voice of a woman echoed through the king’s mind, it lacked emotions, but like a loyal AI, it’s abides by his will.

But he didn’t stop, what he was doing.

"F-Fuck... yesss...AHHH! Deeper, my liege! Don’t stop!... Ahhh I-Im, uuuuooo... I’m cumming!"

The king was buried balls deep inside a small, fairy like monster, her tiny frame writhing beneath him.

She had wild curly neck long red hair, glowing crimson eyes, and dark skin, and strange red markings on her body.

Her beauty was fierce, as it was otherworldly, even more so for her size. She wasn’t any larger than a Barbie doll.

And neither was he.

Two doll-sized monsters, tangled in sweat and corruption.

They where making steamy hot sex on a large stone throne.

His hands gripped her thighs tight, his muscles twitching from exertion as her moans echoed between the stone pillars of the grand hall.

"FFWUUCKK...

He clench his teeth as he keeps drilling and humping away at her tight hungry pussy, her wombs sucking on his monster like cuck with bumpy flesh on it shaft and spike like head.

Painful one would think but these flesh wiggle inside the hungry little minx.

Till the sexy fairy monster wrap her legs around her beloved king’s waist, sensing his orgasm approaching rapidly alongside her own.

She squeeze tight, and with a half craze look, and time as began to cry with a smile, her body crave this.

But her soul did not want this, yet her mind was already broken beyond repair.

Fear, humiliation, and despair; all the bad memories she underwent for the past two years all came crashing back to her in this moment.

All of which excited her body to no ends.

The feeling of being used like this was a helping hand aiding her to reach the greatest climax of her fucking life.

Yet! As her body screams yes, on the inside she was crying.

’I don’t want this someone help me please.’

[If feels so good, yes, oh fuck yes]

’Kill me, how could this queen fall so pitiful, kill me, kill me, kill me before I give in.’

[Give up, the king has claim your womb, this next shot will assured the birth of a new heir]

’Nononono!!! Albedo please help me... I-I was wrong; you were right.’

She muttered to herself, staring at the woman bound in chains before her. Like her, the woman had red hair, but hers was long, flowing to the ground like a scarlet waterfall.

Like the herself, and man, she shared similar features, but the difference with her was the fact that she was size of teddy bear instead.

A variant among her species was the best way describe her.

Her arms were tied tight behind her back. In her ass was a vibrating anal plug, and she wore nothing but a black C-string panty that clung to her skin, molding tightly around the shape of her plump vaginal lips.

She was soaked, drenched beyond reason, and if the panties were removed, it would reveal the hidden dildo extension buried within.

A blindfold covered her eyes, leaving her in darkness, unable to see anything.

And yet, despite that, she was forced to hear it all; the queen’s lust fill moans, loud and unashamed.

Her flawless skin shimmered beneath the castle’s eerie green skylight, the glow of the monster realm casting her humiliation in perfect display.

She trembled and cried.

The blindfold drank her tears.

Her mouth was gagged, but if it were removed, the hate in her eyes would be mirrored in her snarl.

Deep down, she could do nothing. And that pissed her off.

She hated this man.

And more than that, she hated herself for failing her queen.

It gnawed at her how some low-rank nobody managed to acquire such overwhelming power. How he shattered the status quo of their clan like it was nothing.

He had killed the former king and his daughters, offering them up alive to the Reality Eaters, as dark offering and gaining power as a result.

Now, he had full control of the kingdom, and had also enslaved the entire monster clan that where their species, and dared to call himself the Sidhe King.

By custom, their race had no need for names.

They were children of the Great King of Force. Isolated as they where proud. Untouched by ambition, until this bastard came along and destroyed everything for his own dream.

To spit on their ancient traditions, he gave them a name: Sidhe.

It wasn’t even official, and yet he treats it as such.

Only a Progenitor could name a race. And he wasn’t one, he had no right, as such the naming did not stick.

The world did not recognize it, for the monster world only recognize a true king class monster if they sore the race or someone of the same race beats the progenitor henceforth becoming the new one upon eating them.

Another way was to marry into the position.

Lucky for them however the true Progenitor had been born from the Monster King of Force.

But five million years ago, she vanished. No one knew where she went, or what happened to her. Because of that, the Sidhe had remained dormant, and hidden.

Now, alongside humans, they were being worked like dogs. He was mining for something, she didn’t know what.

But it required a massive labor force. Even her precious Knights of Dawn had been reduced to hauling stone like slaves.

Because of him, powerful forces had started to turn their gaze toward their land.

He had ties with the High Demon Ladbras. With the Lamina Queen Medosa. Even the Cain Family’s Royal Guard Commander, Kifril Fallenblood acknowledge this bastard as a powerhouse worth teaming up with.

She couldn’t understand it, how he made so many alliances, how he carved out so many paths.

Thinking back, her heart clenched with bitter regret.

’I should’ve killed that bastard the day he beat Halpix... Why was I so blind? Of course someone this strong would threaten the natural order of our people.’

Her frustration was high, she had lost all hope, yet her will remain unbroken.

Tougher than anyone here.

But the same could not be said for the mind broken queen

In the middle of their rising climax the fairy queen hug him, she had given up, her claws sinking into his back, however as hard as she grabs his durable flesh, it was impossible to penetrate even with her claws that where harder than diamond’s, and sharper than electric saw.

"Alustus...alustus...ALUSSTUSSS!!...

She screamed out his great name in joy, as she cums all over his cock, at the same time Alustus cum deep inside her needy cunt.

As string after strings of thick cum fills her womb, till it flies out her pussy like burst water balloon.

The king raise his head in complete bliss, as he smiles at his artwork

After having what was arguably the best orgasm in his life.

He slowly pulls his cuck out of the Fairy Queen cunt, yet as he pull it out, her soft entrance tried to suck him right back in for another round.

"What a naughty hole, I love it, however I had my filled for the day, coming twelve times back to back without tiring sure is fulfilling though, hahaha...

With a loud pop, he yanked his cock out, and a system notification came to him right before his eyes.

A translucent blue screen materialized in front of him, accompanied by a soft chime.

He chuckled darkly.

"Heh... of course I am picking Option B. As much of an arrogant bitch as she was to me in the past."

He licked his lips, recalling the recent memory.

"She was an incredible fuck. I would be a damn fool to toss away a woman who can please me like that... Hahaha... I am in a really good mood today."

With no hesitation, he selected [Option B].

A second screen appeared instantly right after his descsion.

"Only six days, huh?"

Alustus muttered, leaning back into his towering throne, absently stroking his slowly softening cock.

"My last bloodcell infusion was three months ago, and that one only took two days...

He let out a low sigh, eyes glazing over as memories flooded in.

"But looking back... I can’t forget the mission I got that day...Well it was mor.elike.a warning, but I still want her despite the danger. In this world I am the chosen one after all, it’s only natrual my great self being a reincarnator from Earth Japan as the Main Character of this world has equally overpowered enemy I must face, truly cliche."

A low, perverse chuckle escaped him.

"I am destined to be strongest after all, Hahahaah... how could I be worry, I don’t care if this mate is some kind of God, soon even they will be squash beneath my feet as I take their woman for myself, I want Minerva, and I will get her?"

"Ohh she truly moves my heart, how could she not? After that day, oh yes that was the day I think I actually fell in love for the first time. The day I thought I was gonna die. Ahh power so radiant and unmatched I saw both the end of the world... and its beginning."

His voice lowered even more in that moment, as he simps even harder.

"Every damn night since, I fantasize about her. She passed through here a few times... but three months ago, I really saw her. Her true beauty up close for the first time."

Alustus said with glee, while Ollustis lay sprawled across the throne, her body twitching, legs sticky and dripping with his cum, her face slack with a fucked-dumb expression.

She didn’t even twitch as he sat forward, fingers sliding through his system interface, scrolling through memories he couldn’t forget.

His first mission that turn into a warning instead.

He opened the [Mission HUD], scrolling past dozens of completed objectives until he found it, the one mission that refused to fade from his mind.

There she was.

A still image of flying Minerva passing the Star Gaze Death Sea.

She always pass this place faster than light making it hard for the system to capture her but one day she seems to have taken notice of them, and slow down to observe, not that he mind.

But that one instance finally made her visual image clear instead of the usual purple blue he was use to seeing.

Her data was under the [Offering System - Emergency Classification].

RECOMMENDATION: DO NOT APPROACH MINERVA!!!

[Survival probability is unknown, attempt this mission at your own risk, but I would suggest to not take it at all. This unknown entity has too much unknown factor to its existence, as such the Offering System cannot gauge the difficulty of this mission]

That was the Alustus came across something he never expected to happen.

In the NovelFire he read in his past life, the system was an absolute power but in this world, power system where determine solely by feats alone.

So when he suddenly reincarnated after a heart attack during one of his gooning session back in his old world and suddenly got Isekaied to this one, with this mysterious system he thought he was unmatched in potential.

But seeing how it crash made something crystal clear to him, the system might not be the ultimate absolute power he might have deluded himself for it to be.

But he learned about the Monster Kings, and how they where the strongest existence, strong enough to challenge even the gods if not outright kill them.

So with that in mind, he figured the system wasn’t the ultimate power, rather it was the ultimate guide that was created for him to reach the ultimate power, which was to become the next Monster King of Force.

And once he reach that level, he was sure nothing in existence will be able to challenge him, not even Losdeus itself.

"Oh well, one day she will be mines, for now however, what the status on that intruder?"

But as he sat there, he didn’t expect his system to say this.
