The Invincible Full-Moon System

I couldn't use any of my stronger skills or spells.

Pneuma spells and moon abilities, I can't use any of them while he could use his.

The First Breath impaired most of the stronger spells and skills in his arsenal, Rex couldn't use them properly and was heavily restrained because of that. On the other hand, Demon Lord Ranath doesn't seem to have that kind of problem.

Is it because the Demon God is stronger?

A question appeared inside his mind, however, he put that in the back of his head.

Currently, the extreme moment would need his full focus.

"It is not you but me who would teach the meaning of fear in this fight!" Demon Lord Ranath's thunderous voice echoed from the sky, he was drowned in maniacal laughter as he envisioned Rex's demise with his hands.

SWOOSH!!

Rex gazed up to the sky and found that it was dyed completely crimson.

His eyes bear witness to the devastating fire and monstrosity coughed forward from the deepest corner of the underworld, followed by countless meteors that decorated the sky with their harrowing arc that looked beautiful to the Demons.

Synchrony of millions of soul that cries in anguish could also be heard as this continues.

But the sight that set Rex's eyes ablaze made him excited.

A gush of adrenaline coursed through his veins, filling him with relentless exhilaration. This moment delighted his soul and rejuvenated his mind, something he had dearly missed, and had been absent lately.

This is how a fight is supposed to go, this is what I wanted! 

Lately, he has always been overwhelmed by the opposing power that pressed against him.

Encounter with the Executor, the sudden attack from the Storm Prince, and even the combination of attacks from the Lunirich Gods. All of them could hardly be called a battle, it was only him trying to survive against their onslaughts.

It was a matter of life and death, he was pressured beyond his limit.

However, that's not the case against Demon Lord Ranath, the pressure just seems right.

Rex's lips subtly curled at the sight, but upon closer examination, they quivered, barely being restrained. A smile that tethered on the edge of jubilation, concealing an uncontained thrill beneath the facade of composure.

But this doesn't last long as his emotion breaks free.

"HAHAHAHA~"

Spreading his arms to the side, Rex laughed maniacally as he gazed at the incoming doom.

Fear...? Teach me fear...?! 

I have been walking in the thread of life and death ever since I was young!

Swish...

His eyes gleamed with a sadistic glint, suggesting that he took Demon Lord Ranath's words as an insult to his entire journey. Slowly, his King Mark, a full moon shape divided into halves of black and red, shimmered even more brilliantly and intensely.

Not once have I ever run from danger and feared for my life.

And you think you would teach me fear through this...? Don't fuck with me, measly Demon!!

KABOOM!!

A powerful booming sound resounded as a violent shockwave exploded from Rex's body.

"Haarrgggh....!!"

Rumble!

Putting his entire focus on confronting this attack despite his weakened and disadvantaged state. Black lightning started to dance around him, red force started to steam stronger across his presence, and most importantly, his King Mark was responding to the relentless anger within him.

Upon reaching a certain extent, Rex instantly activated both of his Gladiator Forms together.

It sparked a sudden change in his appearance.

Meanwhile, watching this from the side was none other than Adhara who was entranced.

Despite the chaos and destruction unfurling before her eyes that was caused by these two horrifying individuals that turned the sky crimson and the ground shaking, her gaze was fixed on Rex who was powering up for the last attack with a huge smile on his face.

'Eh...? I've never really paid attention, but was he always like this?'

Aside from the untamed energies that were coming out of Rex's entire presence, Adhara saw through the emotional aura that he emitted, mixing together and responding to the other energies like fuel to a blazing fire.

Somehow, the colors caught her eyes, and she couldn't look away from them.

One is a vibrant enthusiastic red color while the other is a warm yellow that intertwined with each other, the two keep dancing more intensely until eventually, they merge into one, producing a powerful ray of orange-golden color.

'S- Such a beautiful color...'

During this moment of trance, Adhara realized that Rex was actually enjoying this.

Clearly, the orange-golden color represents the excitement, thrill, and happiness that surged inside of him while fighting Demon Lord Ranath. Perhaps, the years of yearning for vengeance developed his love for fighting.

It was usually hidden underneath his hatred. Now that he's free, it is displayed vividly.

Like a gorgeous symphony, the rustling and whistling sound of his energies resonated with Adhara's very soul. A strange serenity settled in, and for a fleeting moment, Adhara couldn't help but appreciate the paradoxical beauty of this destructive combat, where power and excitement converged in an awe-inspiring painting.

Even though he was always driven forward by hatred and anger, that already changed.

During this moment, she could tell that he had changed, truly.

As the hue of hatred subsided, fading away, the radiant orange of excitement replaced it.

Similar to a deadly contagion, upon witnessing this scene, the excitement radiating from Rex was transferred to Adhara, and she sensed her own body responding with intense fervor, lifting her spirit to the peak.

Instinctively, Adhara's aura spiked even higher as her eyes darted to a Demon Captain.

Realizing that Adhara and Huvuki were distracted by the display of powers, one Demon Captain tries to sneak through in order to disturb whatever Rex is trying to do, yet is only met with a powerful kick to the face.

Bam!

Hurtling away, he recovered quickly but was surprised to see a pair of gleaming white eyes.

Splash!

Adhara went ahead and landed a series of fearsome attacks using her seething daggers, stabbing the Demon Captain on his elbows, knees, wrists, and even his neck in quick succession which happened in under a second.

"Where are you going, Demon...?" She asked with a haunting voice.

In the following second, the Demon Captain loses his power due to the attack, "Huh...?"

"Don't go anywhere, your opponent..." Adhara said and paused, raising both of her daggers upwards. A peculiar purple string of fire, way stronger than before slithered on her arms and circled her daggers. "Is me!"

Slash!

Slashing in a circular arc, she sent the Demon Captain crashing away across the ground.

Upon taking care of the Demon Captain, Adhara straightened her back before she glanced over her shoulder. "Leave the other things to me. Seeing you like this... it made me very happy. Go for it, Rex" she whispered tenderly.

Blitz!

Out of nowhere, the ground around the area turned raven-black.

Haunting inside of the blackened ground is the presence of black lightning. It was the Black Field Orko spell, his favorite spell, expanding throughout the entire area in preparation for Demon Lord Ranath's ultimate attack.

Rex then reaches out his hand before the Silver Eye flies over to him.

Putting it in front of him horizontally, he then focused and infused it with everything he got.

Don't let me down Silver Eye, I'm counting on you.

SHINGG!

Not wasting any more time as the meteors were about to strike, Rex garnered all of his elemental energies, kingly energies, and also red force into the Silver Eye and made it tremble uncontrollably to the brink of shattering.

It's not enough, more power!

Creasing his eyebrows together, he pushes his energies to condense even further.

Although he hasn't ever done it before, he's aware that his control over energies was exceptional thanks to learning to control the stubborn kingly energy. It was not a stretch to say that he's perhaps one of the best in controlling energies.

Under this pressure, he was able to condense his energies extremely.

Barely a few seconds passed and one could already see a combination of the color red, black, and white at the surface of the Silver Eye sword, it was only 1 centimeter thin, the product of condensing his energies to it.

Condensing the energy to this point made it even more chaotic and sharper.

I could feel that Silver Eye could cut through anything right now.

Smiling wickedly, the muscles inside Rex's legs bulged before he lunged himself upwards.

"Let's see who will be the last one standing, Demon Lord Ranath! Raarrggh!!"

"Arrogant! I'm going to teach you some manners, I'll have you pay the fee with your life!"

Swoosh!

Rex leaped high into the air for the ultimate final clash. Behind him were countless black lighting tentacles that were extremely enhanced and thick, soaring upwards like a network of entangling, destructive webs.

On the other hand, Demon Lord Ranath also did the same thing.

Deciding to end this with an ultimate clash, he descends with immense bloodlust.

Flames that came from the depth of hell itself coupled with the countless meteors that were raining out of the gate in the sky followed behind him, exerting everything he had, making sure that the victor of this bout was going to be him.

Kaboom!

Crack!

Splash!

Just before the two clashes, the black lightning tentacles and meteors collide.

Each produced an ear-shattering sound and was able to make the formation barrier wobble even more due to the chaotic mix between lightning and demonic energy, adorning the sky with a beautiful sight of explosion and destruction.

It was akin to fireworks in the night.

But a more dangerous one, the debris that fell was catastrophic.

"Spread out! Don't y'er dare stay in the middle! This is beyond our abilities!"

"Move your asses or you'll die!"

Dwarves Captains started to order a tactful retreat as the clash between Rex and Demon Lord Ranath would be too much for them to handle, the best thing they could do was pause the fight and get into safety first.

Similarly, the Rastrikan Demons were also surprisingly doing the same.

Most of them stayed behind in the hope of sacrificing themselves to distract Rex, however, they were blocked by Huvuki and Adhara who were relentless in their defense. Thus, there's no point in staying behind.

Despite their strong armor-like skin, they were not invulnerable to this.

Unfortunate individuals that got hit by the debris from the meteor were crushed completely.

"Lady Adhara, shouldn't we get into safety too?"

Seeing that Adhara was not moving to safety, Huvuki asked, his face etched with concern.

No matter what, staying here would be reckless.

However, Adhara waved her hand while her eyes were still fixed on the soaring Rex in the sky, gesturing that she wouldn't be going anywhere. "Go on without me, I want to bask in this monumental moment. Besides..."

"Right here beside him is the safest place I could be" She added with a sweet smile.

Although he doesn't understand what she is saying, he is not dense enough to not know that there's a deeper meaning to the moment for her. Huvuki didn't pursue her further and nodded his head in understanding.

Without saying anything, he dashed away to flee and get himself to safety.

On the other hand, Rex could feel the wind resistance brushing against his skin as he soared to the sky. His hands unconsciously gripped the trembling Silver Eye tighter, caressing it with power as Demon Lord Ranath encroached.

Closing his eyes for a second, he then smiled amidst the rush of the moment.

But no matter, I can turn this to my advantage. It's my weapon to protect the others.

I would not allow anything similar to what my parents suffered to happen anymore.

Jolting his eyes awake, Rex's eyes burned with determination as Demon Lord Ranath was already right before him, filled with extreme bloodlust. However, Rex welcomed him with a brutal smile etched on his face.

"I'll send you back to where you belong, Demon..."

"When I'm finished with you, even the depths of hell will learn to fear my name!"

KABOOM!
