This is a story that no one knows, buried in the river of history.

At that time, humans were just humans, with no division between the Imperials and the barbarians.

And the hero named Karolgaris led the humans, driving the Bronze Kind of the Iron Kind into their rightful place.

After that, it was the era of the rise of the Iron Kind.

But after Karolgaris expelled all the bronze bells and protected the Iron Kind, people killed him.

"How could this be! You are a hero!" puzzled people said.

"Now I am still a hero, but soon I won't be," Karolgaris replied.

"Regardless, we can't kill you!!!" people pleaded desperately to Karolgaris.

But at that time, Karolgaris shook his head.

"I don't want to become a monster and hurt you afterwards," Karolgaris said.

"How could you! How could you be a monster!"

"The monster is here, relying solely on the Iron Kind, it was impossible to repel the endless Bronze Kind." Karolgaris touched his chest.

"But!!! You are our hero!!!" people cried.

Karolgaris did not continue speaking.

"In that case, imprison me, create a prison that I cannot escape from no matter what, a prison that I cannot escape from even after a thousand or ten thousand years." Karolgaris knelt down to the people.

The hero of the Iron Kind, Karolgaris, kneeled.

People finally endured their helplessness and built the prison.

Karolgaris put on his armor, picked up two large swords, and entered the prison by himself.

"Ah... the sky is so blue." Karolgaris took one last look at the azure sky.

Then darkness surrounded him, and the doors of the prison closed.

This is a prison that can support thousands of years.

The Black Swordsman moved heavily with each step.

The closer they got, the more nervous the adventurers became.

Then, the Black Swordsman stood still, raised his head, and slowly surveyed his surroundings.

"What's up with that guy?" Some adventurers were confused by the behavior of this stranger.

As if lost in confusion.

"Focus on the Black Armored Knights in front!" Nisa's voice suddenly rang out.

"Yes!!! Let's deal with these guys first!" The adventurers thought it was more important to deal with the Black Armored Knights in front of them.

"Dang!!!!!!"

The Black Armored Knight's sword slammed fiercely against Brey's sword, creating sparks.

Brey took several steps back, his face pale.

If it wasn't for "Last Sound" being tough enough, Brey would have been cut in half along with his sword.

But even so, Brey still felt like his hand bones were about to break.

This was the result even after relieving some of the force-

"What's wrong with you? You've been acting strange since earlier!" Brandy, who was fighting on the frontline, shouted at Brey.

Brandy had never seen Brey scared before.

And Brey had never seen himself so scared!!

Even when facing Jallu, Brey had never been like this.

The more they knew, the more afraid they became.

"He's only D-rank! If you're not focused, you'll die!!!!" Brandy kicked Brey.

Then the space where Brey was standing was split by the Black Armored Knight's sword.

"Phew... sorry." Brey took a deep breath.

- "Yeah, if you're just a D-rank fish, if you're not focused, you'll die."

The adventurers continued to battle the Black Armored Knights in a chaotic scene.

Suddenly, the Black Swordsman, who had been standing still, looked at everyone. A momentary red light flashed from under his helmet.

"GUAAAAAAAAAA—"

A beast-like roar suddenly rang out from under the helmet.

The Black Swordsman took a step forward, his movements incredibly smooth, completely unlike the stiffness of the Black Armored Knights.

The bricks that had never cracked before shattered into pieces under the Black Swordsman's footsteps.There was a pitch-black swordsman standing about a hundred meters away from the crowd. He dragged his large sword without any reason and swung it.

An invisible force swept towards the crowd.

Countless stone pillars were split in half, and the destruction continued until the end.

Bricks and boards were lifted by the force and then shattered.

Silence...

The entire arena suddenly became quiet, with no sound at all.

Only the smell of blood became stronger, covering up the previous stench.

Apart from those who immediately lay down, no one else survived.

They were cleanly cut in half by the force of the sword, falling to the ground with a shocked expression.

Not even the black armored knight was spared, they were all wiped out.

The blood was still warm, flowing through the cracks in the bricks.

"Ah ah ah ah ah ah!!!!! Who is that person?!" Suddenly, someone screamed.

Whoever was screaming abruptly stopped.

At some point, the pitch-black swordsman had swung his sword again and cut the noisy person in half.

Nessa's face had lost all color, her eyes were trembling, and she looked in fear at the knight sword in her hands, which had been broken into several pieces.

"What is this..."

"It's an S-rank monster... no... that's not right..."

Nessa's mind was in chaos.

The power of this pitch-black swordsman surpassed Nessa's understanding.

Those stone pillars, those bricks, even if Nessa used all her strength, she wouldn't be able to cause even the slightest damage to them.

But they were destroyed by this pitch-black swordsman with a single swing... destroyed by more than half.

Clasping her trembling right hand tightly, Nessa tried to calm herself down.

"Son of Light, my lord, give me courage."

"Holy Courage!!!"

Nessa stood up again, her face showing determination.

Holding onto her intact shield, Nessa stared directly at the terrifying pitch-black swordsman.

However, the pitch-black swordsman did not look at Nessa. He looked around in confusion.

After a while, he turned his head towards Nessa, who was ready to strike.

"Charge!!!" Nessa shouted and rushed forward.

"The knight's creed is to protect everything!!!"

At this moment, Nessa attacked the pitch-black swordsman without hesitation.

The more devout the user of "Holy Courage" is, the greater the enhancement to their strength!!!

Although Nessa would later fall into a state of extreme weakness!

But Nessa, whose strength was already close to S-rank, could defeat even S-rank adventurers with this enhanced attack imparted by "Holy Courage"!!!

"Peng"...

Nessa's delicate body flew backwards like a kite with a broken string, crashing into countless stone pillars.

The powerful desperate attack seemed like a joke in front of the pitch-black swordsman.

Nessa, who had finally stopped, coughed up blood violently.

Her shield had long been shattered into countless fragments.

Her lightweight armor also shattered, providing no protection for Nessa.

Her armor fell off, revealing a large amount of snow-white skin, with a faintly visible tattoo on her chest.

Despite being heavily injured, Nessa was not dead.

Nessa struggled to keep her consciousness from fading.

To survive such a heavy blow was already considered a miracle.

"Oh lord... thank you... but Nessa may not be able to escape this trial..."

When she was struck, a golden magic circle appeared in front of Nessa, blocking some of the impact.

On Nessa's chest was the tattoo given by the "Son of Light" to its esteemed and devout believers.

Once in a lifetime, in a moment of crisis, it would protect the bearer from harm.

Not even dozens of S-rank adventurers could harm it.

The pitch-black swordsman seemed to ignore Nessa's intentions and took step after step towards the terrified adventurers.

The remaining adventurers had no thoughts of resistance anymore.

"Ah ah ah!! Help me!!!" Only a few adventurers were left, fleeing and crawling in all directions.

Only a few were brave enough to face the pitch-black swordsman.

And probably the only one who could withstand a swing from the pitch-black swordsman was Nessa, who was currently lying motionless in the distance.

"Monster!!! Ah ah ah!!!""Don't come any closer!! Ahh!!"

The Dark Swordsman took what seemed like a slow step, but instantly appeared in front of a fleeing individual wearing heavy armor.

"Don't!! I beg you!! Don't!! No--"

The head was severed, and the pleas of the fleeing individual did not reach the Dark Swordsman's ears.

The Dark Swordsman remained silent, taking another step forward.

With a slow step, it was as if the Dark Swordsman ignored the distance and instantly appeared somewhere else.

The large sword in the left hand cleaved down, followed by the large sword in the right hand slashing to the other side.

Bloody roses bloomed, but no one dared to appreciate them.

Fear crawled up the spine, assaulting the minds of everyone.

Screams gradually subsided, and cries of despair became fewer and fewer.

Countless mutilated bodies lay scattered in the arena.

Over two thousand adventurers had all turned into lifeless corpses.

However, a dozen or so people still lived, but unfortunately, most of them had gone insane.

"Hahaha! Monster!! Hahaha!!"

One of the crazed adventurers writhed and pointed towards the Dark Swordsman.

"I'm not afraid of you! Hahaha!" The insane laughter was terrifying.

"Sssh--"

No words. The Dark Swordsman raised his hand and struck down, cleaving the person from head to toe.

It was a nauseating scene, but there were no more living people to vomit.

The Dark Swordsman approached Virginia.

There was no life left in Virginia's eyes, only deep despair that made her give up all hope.

"Miss!! Hide behind me!" Brangie opened her arms.

Although it was clearly meaningless, Brangie still stood in front of Virginia.

"Brangie..."

"Rest assured... I'm here." Brangie turned her head and showed Virginia a gentle smile.

"Brangie!! No!!!" Virginia's eyes regained their color of dissatisfaction, and she cried out in fear.

The Dark Swordsman raised his right hand, and in Brangie's eyes, time seemed to slow down.

She could clearly see the appearance of the falling sword.

-"Oh, the dark sword... truly ominous..."

"Peng!"

A sword with a rolled edge smashed into the Dark Swordsman.

The Dark Swordsman turned his head towards the direction the sword came from, letting go of his own sword.

Brey's forehead was covered in cold sweat, but there was no sign of fear on his face.

While the Dark Swordsman was stunned, Brey quickly rolled away and picked up "Last Sound."

"Clang--"

Then, with the left hand, the dark sword cleaved towards Brey's back.
