The Academy’s Weakest Became A Demon-Limited Hunter• Chapter 299

”If Charlotte, the number one magic authority in the Zelver Empire and archwizard, had been here, she might have been able to protect Aldreque from those demons somehow. The Imperial Wizard barely managed to stand, threw himself through the breached outer wall, and used wind magic to lift himself and fly somewhere. White understood that the Elemental Kings had appeared to stop a powerful demon, but she didn’t have the mental capacity to focus on that situation.

Above the iron sea that filled Aldreque.

Those who couldn’t evacuate to shelters fled to higher ground.

Thanatos the Ruination scattered annihilation mana as he glared in the direction of Aldreque.

It had the ferocity of a beast that had found its prey.

“If only Charlotte had been here…!

”If Charlotte, the number one magic authority in the Zelver Empire and archwizard, had been here, she might have been able to protect Aldreque from those demons somehow.

However, Emperor Carlos had brought only his elite forces to Aldreque.

No one, except for those who orchestrated the event, could have foreseen such a disaster.

In the distance, eerie mana began to gather in the mana stone attached to Thanatos’ staff.

Emperor Carlos swallowed nervously.

It was grand.

A magic circle of immeasurable size unfolded, ready to cast a spell of destruction.

Thanatos extended his staff in the direction of Aldreque.

“Your Majesty, at least evacuate Princess Snow White, if only for her sake!!

”“No… Stop it.

There’s no other way.

”“But!

”“Relay this to everyone in the frontlines of the Imperial Wizard Unit!

Even if it means exhausting their mana, they must pour out their mana at full power and protect Aldreque!!

”“I will… obey your orders…!

”The Imperial Wizard, who had barely regained his senses and was casting a healing spell on himself, replied.

It was merely a healing spell for emergency treatment, but it was enough for him to force his body to move.

The Imperial Wizard barely managed to stand, threw himself through the breached outer wall, and used wind magic to lift himself and fly somewhere.

And then.

[Graaaahhh!!!

]Thanatos roared.

The condensed mana in his staff seemed ready to shoot at any moment.

It was a power that killed instantly upon contact and even burned the soul.

The undeniable and terrifying mana ripped through the ground and blanketed the sky, striking fear into the hearts of humans.

Aldreque held its breath.

Emperor Carlos felt it in that instant.

The power couldn’t be stopped.

Even if the Imperial Wizards there deployed a barrier at maximum output, it wouldn’t be enough.

?…It was then that the strange event occurred.

Rumbleeeeee!!

Boom!!!

A blinding flash of light.

Afterward, a vast expanse of purple lightning rained down on Thanatos from the sky, like divine judgment.

Unlike lightning that vanishes in an instant, the lightning blast raged like a storm, relentlessly engulfing Thanatos.

The strike radiated a dazzling brilliance, even from afar.

Crackle!!

A man formed from lightning mana appeared before Thanatos, floating in midair.

A billowing black coat billowing and purple hair.

From Aldreque, his exact form couldn’t be discerned, but it wasn’t hard for anyone to recognize who could wield such powerful lightning magic.

His mana could be felt even from far away.

He was already a wizard beyond comprehension.

“The Lightning Sovereign…?

”The Lightning Sovereign, Jaul Dragoniac.

The Elemental King of Lightning stood against Thanatos.

Fwooooo!!!

A swirling water magic of brilliant colors merged with the lightning.

The pressure of the deep sea weighed down on Thanatos.

Its power was more than enough to devastate the entire area.

Another water vortex appeared around Thanatos and gracefully spread, revealing a beautiful woman inside.

Her blue hair flowing, she smiled.

It was the Water Sovereign, Siren Silivian.

Whhooooooo!!!

A terrifying tornado mixed with the lightning and water vortexes, amplifying the momentum of the elemental magics.

This level of Mana Mastery was beyond imagination.

In the world, few could perform a joint spell with the magic of an Elemental King that if one were to count them on one hand, they’d still have fingers to spare.

A petite woman enveloped in light green wind appeared.

A thick arm, formed of dense wind mana, materialized in midair above her head, gripping a massive bow made of wind.

The bowstring was drawn, and an arrow formed of wind mana aimed directly at Thanatos.

The woman blinked expressionlessly.

She was Erin Campbell, the Wind Sovereign.

Whoooosh!!!!

Crimson flames surged, engulfing all the elemental attacks of the Elemental Kings.

The ultra-high-temperature flames intertwined with lightning, exploding incessantly.

As the flames and lightning evaporated the water, intense steam explosions ensued.

The tornado utilized the resulting aftermath as part of its attack, leaving nothing unused.

Space warped from the astronomical mana.

The layered joint attack was nothing short of a disaster.

An elderly wizard, wreathed in flames, walked forward slowly, his wizard robe fluttering, staff in hand.

Behind him, countless fire magic circles unfolded.

Like fine wine, his mana, condensed over long years, weighed heavily on the area.

The Elemental King with a long white beard.

He was the Fire Sovereign, Andersen Versando.

“The Elemental Kings… All of them have joined the battle….

”Merlin spoke in a trembling voice.

“They must have judged that this demon was an immediate threat to the world.

”Emperor Carlos instantly understood the reason the Elemental Kings appeared.

It was the Zelver Empire.

Naturally, any incident that occurred there fell under the empire’s jurisdiction.

However, no matter if the event occurred within the empire’s territory if there was an imminent risk of catastrophe striking the entire world, the Elemental Kings would appear voluntarily to join the fight.

At that point, it was no longer just an issue under the empire’s jurisdiction; it became a matter where the whole world must unite its strength.

Neither the Abyss nor Rachnil, the Iron Fairy, was an immediate threat to the world.

When the Abyss appeared, it merely became the night sky, observing the world, and Rachnil has only occupied Aldreque so far.

On the other hand, it was clear that Thanatos posed an immediate and immense threat to the entire world.

Paaaaah!!!

With Thanatos’ roar, the magic of the Elemental Kings was driven back and extinguished by dark green flames.

The condensed annihilation mana in Thanatos’ massive staff dispersed, but the elemental mana that spread throughout the area was slowly absorbed by him.

Thanatos scanned the Elemental Kings that had appeared all around him.

“Not a single wound?

To absorb all this mana… What an intriguing demon.

”The Lightning Sovereign Jaul admired.

A demon that absorbed even the mana of the Elemental Kings to fuel its growth.

Its limits did not exist.

“If we use magic, it absorbs the power and becomes stronger.

Hold it off until we figure out how to defeat it.

”Wind Sovereign Erin Campbell spoke in an emotionless voice as she infused her wind arrow with mana.

“Is the absence of familiars due to the power of the fairy?

For its influence to extend this far, that’s impressive.

”Water Sovereign Siren Silivian looked at the distant Iron Sanctuary with a puzzled expression.

“It seems the Ice Sovereign is dealing with a fairy.

The Ice Sovereign is powerful, but even he would find it difficult to defeat a fairy…”No matter how strong the Ice Sovereign was, he was still just an ice wizard.

To defeat a Fairy, one ultimately needed the power of a Fairy.

“If it’s the Ice Sovereign, he’ll manage somehow.

Do you think the strongest of us would face the Iron Fairy without a plan?

”As the Fire Sovereign swung his staff, an immense wave of flame spread out.

“We will deal with this demon.

”The Elemental Kings spread their elemental mana as they prepared to fight Thanatos.

“Senior Isaac…”“White?

Can you move?

”As Snow White suddenly approached the broken outer wall, Emperor Carlos asked in a worried voice.

White understood that the Elemental Kings had appeared to stop a powerful demon, but she didn’t have the mental capacity to focus on that situation.

She looked outside.

A dull, ashen sky and a sea of iron.

The towering fairy sanctuary stood in the distance.

A gust of heavy wind blew, making White’s hair and clothes flutter.

“Haa.

”White closed her eyes.

─ The power of the fairy you possess will surge when the fairy disrupts the balance.

Your body temperature will spike then.

Keep a firm grip on your consciousness and try to master your mana.

It will be difficult, but remember, that power is yours.

Isaac’s image, often seen by the beautiful lake at the corner of the Hydrangea Garden, filled her foggy mind.

Even though she was close to him, there were many times when she felt like he was far away.

Like someone gazing at a distant place.

White didn’t know what, or what kind of scenery, he was looking at.

All she knew was that Isaac often seemed lost in deep thought.

That face always looked full of worry…Even though he didn’t show it, she could tell.

She had learned to discern those lost in thought, having faced assassination attempts since childhood.

Lately, Isaac’s worries seemed to have deepened even more.

Isaac seemed to consider relaxing or chatting as luxuries and lived his life in pursuit of even the slightest bit of efficiency.

A person like him probably wouldn’t have the time or patience to keep meeting someone as useless as White had become.

Why, then, was Isaac so deeply troubled?

It was as if he were someone about to plunge into hellfire at any moment.

Surely, there must be a deep reason for his worries…Whatever it was, it must have been something far scarier than anything White could imagine.

Senior Isaac.

It’s only right that I repay you for all you’ve done for me… No, it’s not even about repayment…You are selfless, a man who would sacrifice his own body to protect others.

Helping you means protecting the people.

This is for the sake of the Zelver Empire…No, it’s not even about that…White shook her head.

She realized.

Had she considered such self-serving calculations?

No, she simply wanted to protect Isaac.

She clutched her head as a violent headache throbbed.

Her breathing became rough, her mouth dry.

She felt like she would vomit at any moment.

Merlin tried to support White, but she extended her arm to block her.

She needed to focus.

“I’ll… help you…”White extended her hand toward the Iron Sanctuary.

Closing her eyes, she focused on the mana coursing through her.

Thanks to the painful mana mastery training she had endured with Isaac, she could vividly feel the mana flowing through her mana circuits.

The days of training under Isaac’s guidance, shedding sweat and blood, and her firm resolve to protect him, heightened White’s concentration to its peak.

Her racing heart slowly began to calm down.

Her breathing became steadier, and her mana came under her control, responding to her will.

White transferred another stream of mana circulating inside her body to her fingertips.

Soon, vivid mana gathered at her fingertips.

The navy blue mana held a glow of white light as if plucked from the night sky.

“White, what is that…?

”Emperor Carlos was astonished, but White paid him no mind.

She could sense the terrifying presence of creatures spread across the world.

She opened her hand.

Somehow, she felt like she could grasp the iron mana floating in the air.

Slowly, White was stepping into a new realm.

“If you’re going to protect the people…”White’s eyes slowly opened.

A strange blue light hovered in her eyes.

“I will protect you…”At last, White clenched that hand tightly.

Fwoooosh!!!

Starting from White, gentle navy blue mana fluttered like a butterfly’s wings, spreading rapidly.

Startled, Emperor Carlos and Merlin stepped back.

The mana was a power imbued with the energy of the night, a blessing from the Fairy Nix.

The Iron Sea was steadily devoured, and the Iron Sanctuary was engulfed by the mana of the night.

The reclaiming of the sanctuary.

It was the power of the Night Fairy.

From all directions, fairies turned into colorful meteors, streaking across the sky and simultaneously heading toward the Iron Sanctuary.

At the Iron Sanctuary, Noah had already pushed himself to his limits and was on the verge of collapsing.

Before Noah fell, Isaac had activated the power of his obsidian blade, [Rock Sovereign’s Barbican], which had a long activation time.

Isaac’s party, including Noah, who was slumped down and gasping for breath, was protected by the beautiful rock fortress walls.

Kakakakakrak!!!

Rachnil’s iron magic was gradually growing in intensity.

There was no doubt that he had recovered to the point where the accumulated damage seemed meaningless.

Unless certain conditions were met, it would be impossible for a human to defeat a Fairy within their sanctuary.

With a greatsword swinging through the air, Rachnil, holding a single greatsword, charged toward the [Rock Sovereign’s Barbican].

A high concentration of iron mana permeated the greatsword with tremendous force.

[You’re merely a human brat!

]As Rachnil prepared to strike the [Rock Sovereign’s Barbican] with numerous greatswords…“Thank you, White.

”Isaac’s calm monologue.

Suddenly, Nix’s magic swallowed the Iron Sanctuary, and Rachnil’s magic lost much of its strength.

[Why… the sanctuary…?

]Everyone present could feel it.

Rachnil’s power over the area was dwindling at an alarming rate.

The power of Nix, the Night Fairy.

The reclaiming of the sanctuary.

Rachnil had lost his control over the sanctuary.

Kwakakakang!!!

[Urgh!!

][Rock Sovereign’s Barbican] shattered, and at the same time, Isaac appeared, swinging his obsidian blade at Rachnil.

Startled, Rachnil blocked the rock blade strike with the greatsword in both hands, but he couldn’t stop the devastating shockwave.

[Stone Breathing-First Form] — Yellow Wave Slash.

Rachnil flew back like a ball and smashed into the wall, while the greatswords floating in the air shattered into pieces from the shockwave of the rock mana.

“Now…”Isaac gave Rachnil, who wore a bewildered expression, a cold glare.

“…It’s time for me to fight back.
