However, before the members of the Flaming Rose could even form a proper defensive formation, Nyx had already taken a step forward.

She casually swung the Holy Sword in her hand.

FWOOOSh!

A golden sword aura stretching dozens of meters instantly tore through the air before sweeping across the battlefield with unstoppable force.

BOOM!!

The dozen or so Flaming Rose members at the front didn’t even have time to scream before their bodies were completely swallowed by the terrifying Holy Light slash.

In the blink of an eye, they exploded into clouds of blood.

Seeing that, everyone behind them instantly turned deathly pale.

"Impossible!"

"A Holy Knight!"

"No... It’s Nyx Cromwell!!"

Fear rapidly spread through the crowd, and several people instinctively began retreating.

Unfortunately, Nyx had no intention of giving them a chance to escape.

Blinding pillars of Holy Light continuously descended from the sky.

Every impact was accompanied by a violent explosion that shook the entire underground entrance.

In less than half a minute, every single guard stationed at the entrance lay dead in pools of blood.

Throughout the entire battle, Nox quietly stood in the rear without making a single move, simply watched his sister fight.

Compared to a few months ago, Nyx’s movements had become far cleaner and more decisive.

Clearly, during the time he had been away, she had experienced countless life or death battles.

Because of that, she had grown to an entirely new level.

As he watched his sister’s back while she fought, a faint smile gradually appeared on Nox’s face. His eyes unconsciously filled with genuine relief and pride.

Just then, Nyx suddenly stopped moving. She slowly turned around and met Nox’s proud gaze.

The air fell silent for several seconds.

Nyx frowned slightly.

"...Why have you been staring at me this whole time?"

Nox blinked.

"Hm?"

Crossing her arms, Nyx looked at him with obvious disgust.

"Like some kind of creep."

Nox: "..."

After several seconds of silence, he finally let out a quiet laugh.

"I was just thinking that you’ve really grown. You’re so much stronger than when I left. Seeing who you’ve become now... I’m truly proud to be your big brother."

The moment she heard those words, Nyx’s entire body noticeably stiffened.

Almost instinctively, she turned her face away so Nox couldn’t see her expression.

"...How boring."

Although her voice remained as cold as ever, Nox still clearly saw the tiny smile that uncontrollably curled onto the corner of her lips.

It lasted for only a brief moment before she quickly suppressed it and returned to her usual indifferent expression.

"Let’s go."

"There’s still a lot of people waiting for us inside."

With that, the two siblings continued walking deeper into the underground base.

As they ventured farther underground, the scale of the base far exceeded both of their expectations.

One enormous underground corridor after another stretched endlessly in every direction, forming what resembled a gigantic subterranean maze.

Torches burned along both sides of the walls, causing the dim passageways to flicker between light and darkness.

The air itself was permeated with an overwhelming stench of blood that was enough to make anyone nauseous.

Not long after they entered, large numbers of Flaming Rose members received the alarm and hurried toward them.

However, none of them were even qualified to slow the siblings down.

BOOM!!

With a casual wave of his hand, Nox unleashed countless streams of blazing orange flames that instantly engulfed the entire corridor.

The blazing inferno devoured everything in its path as agonized screams echoed endlessly beneath the earth.

Elsewhere, the Holy Light released by Nyx continued blooming across the battlefield.

Every beam of Holy Light that descended marked the end of another enemy’s life.

Anyone foolish enough to charge at them fell almost instantly.

Not a single person could survive even one attack from the brother and sister!

Everywhere they went, bodies continued piling up. Blood nearly dyed the entire underground passage crimson.

Finally, when they arrived at an enormous underground hall, Nox slowly came to a stop.

The next second, his expression turned completely cold.

In the center of the hall, dozens of massive iron cages had been lined up.

Inside those cages, a large number of young Beast Tamers were imprisoned.

The oldest among them were only seventeen or eighteen years old.The youngest were barely seven or eight. Many were covered in wounds. Their clothes had long since been soaked crimson with blood.

Several children were curled up in the corners of their cages, trembling uncontrollably. The light had already disappeared from their eyes. The entire hall was engulfed by an overwhelming atmosphere of despair.

However, when those children saw Nox and Nyx appear, the lifeless eyes that had already lost all hope slowly lit up once more.

"S... Save us..."

A little girl whose voice had long become hoarse used the last of her strength to whisper.

Nox slowly clenched his fists.

Crack.

The sound of his knuckles grinding echoed throughout the hall as his gaze became unimaginably cold.

"These animals..."

...

At the same time, deep within the underground base, a Flaming Rose member drenched in blood desperately sprinted toward the deepest part of the headquarters.

His face was filled with terror, as though some horrifying monster were chasing him from behind.

"Sir!!"

"Sir!!"

He stumbled into the deepest hall of the base before collapsing heavily to his knees, gasping for breath.

Inside the hall, a towering figure stood silently with his back facing everyone.

His body was exceptionally muscular. His broad back resembled an insurmountable wall. And Embroidered upon his cloak was an enormous crimson Flaming Rose.

"Sir!"

The member knelt on the ground, his voice trembling uncontrollably with fear.

"Nox... Nox Cromwell has broken into the base!!"

The entire hall instantly fell silent.

After a long moment, the massive figure slowly rose to his feet.

A deep, icy voice echoed throughout the chamber.

"Seal the entire base. No one is allowed to leave."

After saying that, he slowly turned around.

Within those eyes overflowing with killing intent, cold flames burned fiercely.

"This time... I’ll personally deal with him. And put an end to my greatest problem... once and for all."
