Chapter Summary

The Academy’s Weakest Became A Demon-Limited Hunter• Chapter 303

“The Primordial Magic Beast… how could a monster like that exist in this world…”Water Sovereign Siren swallowed hard. If Isaac and the Primordial Magic Beast, Diakan, had fully intended to shatter the barrier of the Elemental Kings, it was impossible to even guess the ease at which it would’ve been broken. The moment all the magic collided, an intense blue light, like a flashbang exploding, filled the barrier of the Elemental Kings.

The iron gates that filled the sky slowly opened, and absolute zero spilled out like a waterfall through the crack.

The Elemental kings and the people of Aldreque gaped in astonishment as they watched the opening of the iron gates.

Boom!

A gigantic black arm of immeasurable size burst out from the crack in the door, tightly gripping it on its sides.

Beyond the arms, inside the iron gate, several eerie red eyes gleamed within the pale blue cold.

Finally, the iron gates relented at the arms’ rebellion, opening completely.

A black monster, transcending life and death themselves, thrust its head forward, revealing its massive body.

[Kaaaaaaaah!!!

]Daikan, the Primordial Beast of Ice, roared toward Thanatos.

Swoosh!!

Cold ripples spread outward from Isaac and the Primordial Magic Beast, Diakan.

Merely by letting their mana flow, the Elemental Kings had to grit their teeth or bite their lips to endure.

Without the barrier of the Elemental Kings, countless humans, including those in Aldreque, would have died in an instant from frostbite and cold.

At Isaac’s will, the place could easily be transformed into hell.

In the mouth of the transcendent Primordial Magic Beast, Diakan, piercing blue mana swirled fiercely.

The amount of mana that swirled and gathered was unfathomable, even for an archwizard.

“The Primordial Magic Beast… how could a monster like that exist in this world…”Water Sovereign Siren swallowed hard.

If Isaac and the Primordial Magic Beast, Diakan, had fully intended to shatter the barrier of the Elemental Kings, it was impossible to even guess the ease at which it would’ve been broken.

Even the Elemental Kings, who made up the core of the world, could not help but feel helpless in front of Isaac.

Meanwhile, Thanatos did not release the condensed mana of annihilation.

His right hand still contained astronomical amounts of mana.

Ian’s [Expelled from Paradise] successfully eliminated the [Veil of the Evil God], but it was limited to just that.

Thanatos remained largely unaffected.

The black magic beast that filled the sky was ultimately a minion of the Ice Sovereign.

Somehow, Thanatos had to bring down the Ice King.

[Graaaahh!!

]Thanatos howled.

He swung his arm, unleashing the full power of annihilation toward Isaac.

Fwooooosh!!!!

It targeted only Isaac.

The dark green flames, which ravaged even the dead and burned their souls, pushed through the cold air and surged forward without hesitation.

The Elemental Kings groaned, pouring all their mana into the barrier.

Whoosh!!

Isaac, as if finding it laughable, fired three masses of [Cocytus].

At the same time, the Primordial Magic Beast, Diakan, unleashed the cold mana stored in its mouth.

The moment all the magic collided, an intense blue light, like a flashbang exploding, filled the barrier of the Elemental Kings.

Boooom!!!!!!

A storm of immeasurable mana swept everything away, releasing an ear-splitting roar.

“Kyahhhh!!!

”Water Sovereign Siren tightly shut her eyes and screamed.

It dawned on her that Erin Campbell’s prior statement hadn’t been in jest.

Brace yourself for mana depletion?

No, even if all the Elemental Kings’ mana were depleted, it would be a blessing if they could just block the impact.

[Graaaaagh!!!

]Thanatos screamed amidst the raging cold and the flood of chilling light.

The density of the mana was so high that there was no sign of the light fading.

Thanatos’ massive, solid body froze and shattered in a brief moment, treading the path to annihilation, but there was still a way to survive.

At the center of the vanishing body, the true Thanatos, protected within an orb of mana, revealed itself.

[Do you really think I’ll be killed… from just this much.

]The flood of astronomical mana, the sharply surging cold, and the unrelenting blue light were eating away at Thanatos’ body.

His life force was resilient enough to withstand if only briefly, the deathly cold surrounding him.

However, it was clear that his body was gradually being destroyed.

He had to escape the icy hell, no matter what.

If he succeeded in escaping, time would be on his side.

He would grow stronger and fight the Ice King again.

However… there would be no second chance for Thanatos.

Vwoooom!!

A sharp tearing sound in the air.

A being wrapped in the chill of the Ice Sovereign flew at incredible speed and thrust its left fist toward Thanatos.

It was Isaac.

[…Ugh!

]It was too late.

He had no choice but to counterattack.

Thanatos, eyes wide open, inhaled sharply before swinging his right fist toward Isaac.

Wham!!

The fists of the two beings collided, sending shockwaves through the air.

Neither side was pushed back.

At that moment, the clashing fists froze and became connected.

Thanatos was flustered.

It was ice created by none other than the Ice Sovereign’s mana.

Thanatos was incapable of breaking it.

“Got you.

”Isaac spoke coldly.

[Did you know… I wouldn’t die that easily?

]“Of course.

How could I not know that your real body was inside that cumbersome form?

”The absolute zero cold consumed Thanatos’ flesh.

A sense of being overwhelmed.

Once again, fear reared its head.

What is this?

What is this being in human form, who dared to tread upon divinity?

Sensing his defeat, Thanatos voiced his question.

[You… what the hell are you?

No, who the hell are you?

]It was a vague question.

However, Thanatos wanted to hear whatever answer Isaac would give.

Isaac pondered for a moment, as brief as a blink.

There was something he had vowed to achieve.

It was a vow he made in the face of Luce’s death, to become a Munchkin, overwhelmingly powerful against the demons.

He would defeat the Evil God.

He would not lose.

“Demon-Limited Hunter.

”It didn’t matter if he wasn’t the strongest person overall.

In this journey, it was enough to become the strongest against one race alone.

He would endure, fight, and win, transforming from the Academy’s Weakest into a Demon-Limited Hunter.

He would move forward toward the ending he desired.

Whoosh!!

Isaac condensed cold mana into his remaining hand.

The swirling pale blue cold.

The magic circle for the 5-star ice spell, [Frost Explosion], rose above it.

Isaac declared.

“I am the one who will exterminate all of you.

”For a moment, Thanatos’ eyes widened as he inadvertently imagined the human before him reaching the pinnacle of all things.

His emotions settled.

Then, Thanatos chuckled quietly.

[Impressive!

]Though his entire body had already been wrecked by the storm of absolute zero, Thanatos gathered the remaining annihilation mana into his other hand.

Brilliant dark green flames flared up.

The one who wielded the power of death was now ready to meet his own end.

[Just try and bring down our god!

]As Isaac released the ice, the two beings reached out toward each other with hands filled with condensed mana.

The two mana forces clashed, and a sharp flash passed as they collided.

The intense cold pierced Thanatos’ entire body, and a fierce shockwave shattered him to pieces.

The howling cold storm swallowed the roar of the explosion.

Fragments of ice scattered, and sharp glaciers viciously flooded in all directions.

Thanatos’ voice faintly echoed in Isaac’s ears.

Thanatos turned to ashes and disappeared.

[Congratulations!

You’ve defeated the demon [Thanatos the Ruination (Lv 2■■)] and gained EXP!

][Level Up!!

Your level has increased to 178!

][You have unlocked the legendary achievement ❰Ah, Death❱!

You have gained 30 bonus stat points!

]The light began to fade.

The absolute zero gradually subsided.

The iron gates in the sky slowly closed and returned to its original location.

The fierce cold wind subsided, and the elemental barrier of the Elemental Kings, having reached its limit, unraveled.

The Elemental Kings, completely drained of their mana, sank to the ground and raised their heads with empty expressions.

At the center of everything stood Isaac, the Ice Sovereign.

Humanity gazed at him in disbelief.

They felt it.

Even if all the power of this world miraculously united into one, they could not defeat that man.

Such an unreasonable and resilient existence.

Without a doubt, the pinnacle of the world was Isaac.

“Haa.

”Isaac’s sigh escaped as a white puff of breath.

He weakened the skill [Ice Sovereign], which he couldn’t handle.

The magic circle with three pairs of wings dissipated, and Isaac began to fall with his bare body.

[Master!

]The Frost Dragon Hilde quickly descended and caught Isaac.

Now at level 178, maintaining Hilde in her true form was effortless.

“Thank you, Hilde.

”[Hmm, if you are grateful, I would appreciate endless petting later…]Isaac sloppily stroked the Frost Dragon’s scales and turned his head to the side.

He passed out.

Ian Fairytale had fainted, held securely in the ice of the Frost Dragon.

Suddenly, Isaac noticed Ian’s hand stretched out to the side, with his thumb raised.

Isaac let out a small chuckle.

And so, they headed back to Aldreque.

“That’s just too much!

Leaving without a single word of thanks?

Even if he is the Ice Sovereign, how can he be this cold…?

Still, that’s part of his charm.

Haha.

” ℞?ℕȏ฿ÊS̩“Yeah, next up, super-aged menopausal woman.

”Water Sovereign Siren shot a glare at Erin Campbell, the Wind Sovereign.

A cross-shaped vein popped on her forehead.

The Wind Sovereign responded nonchalantly, “What are you looking at?

”“What else would I be looking at?

You’re talking nonsense in a situation like this.

”“Haa, Honestly, you two are exhausting.

Stop bickering and assess the situation already.

”Siren furrowed her brows and surveyed the area.

The ruined city of Aldreque was reduced to rubble.

It looked as though the fierce battle had torn the city to shreds.

“I’ve assessed the situation.

The conclusion is simple: from now on, we must live in the shadow of the Ice Sovereign.

”A few of the Elemental Kings nodded in agreement to her words.

There was no longer any need to deny Isaac’s power as the Ice Sovereign.

Isaac was moving away from them, but the overwhelming power he had left behind was etched deeply into everyone’s hearts.

And perhaps, a new order for this world had just begun.

“Truly a remarkable man…”The Fire Sovereign Andersen let out a hollow laugh in disbelief.

“…Let’s head back.

After a brief rest.

”The Lightning Sovereign Jaul steadied his breathing and rested.

It had been so long since he last experienced mana depletion that he could hardly remember the feeling.

However, they were Elemental Kings.

Soon, they would recover enough mana to transform into elemental forms and travel.

As they rested, they quietly watched the white dragon flying off toward Aldreque.

In the aftermath of the battle, the sky began to shower early snowflakes.

The snow blanketing the sky settled around them, like the scars left by the battle.
