The Invincible Full-Moon System

It was easy to determine his target. 

Out of the entire army of Dwarves, there was only one emanating a thick killing intent.

'A Demonified Human...? Or is he just a human?'

Demon Lord Ranath gazes at the figure that is coming straight at him with a frown. A sense of familiarity settled on him when he gazed at the wicked facial expression this figure was wearing that was akin to a demon similar to him.

But the weird part is that this figure doesn't emit demonic energy.

Maybe he was wrong and this figure was not a demon, nevertheless, this made him excited.

Rex was oblivious to what Demon Lord Ranath was thinking, he only kept on sprinting forward and went past the army. In this fleeting moment of rushing in, he could feel the muscles inside his body bulging in exhilaration.

Even his chest felt somewhat elated and soothed, seeing the charging legion of demons.

I don't know if it's because I'm frustrated or I've been dealing with too many matters regarding Dargena City and the alliance or even the fact that I was in a coma, but this... I miss this. I can tell that my body also misses the excitement of a real fight!

Starting from the First Breath, he was cramped in dealing with political matters.

Focusing solely on establishing his new home.

Leaving humanity also means that he was not participating in the war directly, he was a third major party in this world dominated by the war between the other two big parties, and thus he wasn't able to fight as much as before.

Additionally, the big fights he had with the Executor and Supernatural Elders were worse.

First of all, the Executor easily defeated him without an actual fight.

On the other hand, the encounter he had with the Supernatural Elders wasn't a real battle, it wasn't a battle to the death. Instead, it felt more like a chore as he needed to convince them of his capabilities rather than fully immersing himself in the fight.

However, in this fight right now against the Rastrikan Demons, he could fully let loose.

Gaining permission from Elder Tilrith who wanted the Rastrikan Demons dead, and the fact that the other high-rank supernatural races also don't seem to care about them, he could absolutely go nuts right now.

Planting his front foot onto the ground, Rex bolted forward in a flash.

Swoosh!

Kaboom!!

Rex gripped the handle of the Silver Eye with both hands and swung it in full force.

A powerful shockwave, a combination of red force and demonic energy, erupted from the collision of their attacks before the two were locked in a fierce power struggle, vying to overpower the other with a maniacal look that hungered the other's destruction.

"Hmmm, seems like I was mistaken. It turns out to be the infamous powerhouse I heard"

"Now, now... Don't tell me that my reputation scared a Demon Lord"

Rex and Demon Lord Ranath exchanged a mocking banter as the two were stuck in this extreme moment, it was rather a comical sight as both of them seemed to be as excited as the other, gauging from their gradually increasing energy.

In addition, the ground beneath their feet also started to sink under their auras' pressure.

Smiling savagely, Demon Lord Ranath exposed his gruesome fangs.

"Fear...? We Rastrikan Demons never experienced fear, we only inflict it on others"

"Great! That means I get to test if that's true or not!"

Crack!!

Blitz!

Motivated even more now that Demon Lord Ranath indirectly challenged him, Rex circulated the red force that was cloaking his body even more and made it steam stronger while also simultaneously activating his black lightning.

Suddenly, he gains a boost, propelling him forward as he uses the Flash spell.

Demon Lord Ranath was taken aback as his feet were lifted off the ground, propelling him thirty meters backward. His demonic red eyes dilated in shock just before a slashing attack struck his abdomen, sending him crashing away.

Like a bowling ball, his hurtling body hits dozens of red demons that were charging forward.

Rex then stopped and summoned Devo's presence on his back.

A dense mist enveloped the entire icy plain upon Devo's appearance, obstructing the vision of the Rastrikan Demons. Many of them continued to growl and charge forward, eager to encounter either Rex or the army to start their onslaught.

However, in the next second, a rumbling sound came from above.

Out of nowhere, a sudden shift of weather happened as thunderclouds covered the sky.

It's been a long time since you did this Devo, are you confident in an improvement?

[Please, your mana was nothing back then. Now, it's different. I'll show you the improvement]

Rumble!!

While Devo was gathering as much lightning mana that was starting to become abundant in the surroundings thanks to the rumbling thunderclouds, the army had already begun to clash against the Rastrikan Demons.

Sounds and exchanges of a battle permeate throughout the entire icy plain.

Thousands upon thousands of Dwarves embarked on a harrowing battle of life and death, all in a bid to safeguard the future of their dear race, which hung in the balance of ceasing to exist with the awakening of the Rastrikan Demons.

Not having an option to choose is what made them fight fiercely.

If the army was defeated here then there was no hope for the Dwarven Kingdom to survive.

Harnessing their deep connection with the earth element, the Dwarves unleashed a torrent of flying earth blocks and rocks through their incantations while also firing their strengthened arrows and bullets. On top of that, the stronger Dwarves initiated small-scale earthquakes, wreaking havoc upon the demon legion.

Additionally, thanks to the War Maul of Glacia, their spells were stronger.

Compared to firing normal rocks of different shapes, the rocks were not covered in ice.

Despite their rigorous raw strength and power to battle against a force that wanted to end them, the Rastrikan Demons proved to be as resilient as a cockroach, able to sustain horrifying damages and still stand back up and charge again.

It was not without reason that Huvuki suspected that the First Breath made them stronger.

Likewise, Adhara and Huvuki stick close to each other and take on the Demon Captains in the east. There are two of them and they would need to beat or stall depending on how they fare against them.

"Remember, don't use too much power until the Elves finish the domain" Adhara mused.

Upon hearing this, Huvuki nodded his head in understanding.

After saying that, she then redirected her focus back to the Demon Captain who was sprinting towards her, an imposing eight-foot-tall demon adorned in crimson and black armored body. His head bore two formidable straight horns, while a pair of light red imp wings protruded from his waist.

In his hand was a taller crimson trident, oozing greatly with its lethal demonic energy.

Not wanting to wait for the Demon Captain to approach any further, Adhara channeled her purple flames and leaped into the sky, a surge of fiery purple energy propelling her. With the two Dwarven daggers in hand, a pair of daggers she was given earlier, she swung them down.

A pair of two scorching purple arcs of fire shot down aimed at the Demon Captain.

Huvuki also didn't stay idle and swung his hammer down to the space in front of him, infusing icy energy into the earth which made his eyes glow with a light bluish hue, infected by the power of the hammer.

"Glacial Obelisk!"

Kaboom!

Crack!!

Both flaming arcs created a massive explosion upon colliding against the ground.

In the nick of time, the Demon Captain managed to dodge the attack by leaping high into the sky. But the other Rastrikan Demons weren't able to react as quickly and got blasted to smithereens due to that explosion.

More than a hundred got sent hurtling away in all directions.

Additionally, Huvuki summoned a sharp and long ice spike, impaling many demons.

Despite some of them being completely impaled through their bodies, creating gaping holes in their chests, none of them died as their heads were the only place that would guarantee their deaths, unlike the modern demons.

Even then, the other Demon Captain managed to block this ice spike with his trident.

"Humans allying with those wretched Dwarves...?" the Demon Captain in front of Adhara said with a haunting voice, astral and echoing. He then laughed in a maniacal manner, finding humor in this realization. "It appears the Dwarves have thrived in this new era, forming alliances with modern humans"

Upon saying that, the Demon Captain's expression turned hideous. "Unacceptable..."

"This won't do... Every last one of them must suffer, facing a life of misery for their deeds. What they did to us is unforgivable, and those who helped their lives become better, will also pay for the sins through agonizing death!" the Demon Captain continued and flapped his wings quickly.

Roar!!

Letting out a powerful roar, a wave of migraine hits Adhara in an instant.

For a fleeting moment, she struggled to steady her throbbing mind, leaving her momentarily dazed. Oblivious to her, the Demon Captain had closed the distance, poised to strike her down with his trident.

Slash!

However, the sheer scarf moved automatically and blocked the incoming attack perfectly.

Clang!

Upon seeing this, the Demon Lord frowns before he reacts fairly quickly.

"Hellfire Mind..."

Not even wasting a single second after having his attack blocked, the Demon Captain's sinister eyes then flashed with a peculiar light, unleashing a demonic beam that quickly stunned Adhara's entire body in place, akin to the feeling of being turned into a statue.

Following that, the Demon Captain grabbed the scarf and did another powerful slash.

"Kyarghh!" Adhara grunted as she was slashed across her body.

A disturbing amount of blood exploded out of the deep gash that she suffered from the Demon Captain that disorients her mind. Even then, the gash started to heal rapidly, however, the Demon Captain was not done.

Still maintaining the effect of the Hellfire Mind, he raised his trident again for an attack.

At this moment, Adhara tries to raise her daggers desperately.

However, it was futile as the binding power was too strong. In order to break free, she would need to transform into her Gladiator form or her Werewolf form. But she can't do it right now, not until the domain is established.

"Defending the Dwarves is a wrong move, now, regret it as I sent you to hell!"

Smiling wickedly, the Demon Captain intends to finish her off.

However, as he was about to slice Adhara's body into two, Huvuki came and intervened.

Just as the tip of the Demon Captain's trident glowed scorching red from the concentration of demonic energy, Huvuki came in clutch, putting himself on the way between them to protect Adhara from the attack.

In the nick of time, using his ice-armored arm, he managed to thwart the deadly blow.

Despite being a King, he knows that Adhara's life is extremely valuable.

Clang!

Upon blocking the attack with his left ice-armored arm, he swatted the Demon Captain away with a blow to the side with his hammer, sending the Demon Captain crashing back onto the ground, creating a vast crater.

"Lady Adahra, are you okay?"

"I'm fine, it's just hard to fight without being able to go all out"

But as this battle continued, Huvuki and Adhara stopped when it suddenly started raining.

"Hmm...? Black rain?" Adhara mused with a frown.

Huvuki also gazes up, hearing what Adhara said which then makes him confused.

Reaching out her hand, she observed the unusual droplets falling from the sky. Instead of the typical clear water, these droplets were a mysterious shade of black, showing that there's definitely a magical influence behind this phenomenon.

Sure enough, she sensed mana and spirit energy in them.

A particular mark then started to manifest on her palm, shaped like an ominous black gate.

On top of that, both energies were extremely familiar to her.

'Isn't this Rex's energies...?'

Upon realizing that this phenomenon was caused by Rex, she glanced over her shoulder. It was then she gasped when she saw a spirit in the far distance shooting a powerful ray of spirit energy into the sky.

A spirit that was the sole reason for the drastic changes on the battlefield.

"I am the Gatekeeper of the Sky! Devoratar Tridan!!"
