The Invincible Full-Moon System

Blood.

It was the ultimate seduction.

Rex swiped his claws and killed a voidal monster.

Blood screamed across his face, still warm from the last breath of the voidal monster he killed, forcing him to swallow hard in restraint. His Werewolf side was churning, activating, begging him to be let out as his body wobbled on the edge of transforming.

Even his lips parted slightly—his desire to devour flesh was barely contained.

But he managed to hold it all in.

Rex didn’t remember how long he had been dwelling deep within the horde’s ranks, probably almost a minute already, but he kept going. The dark dome was already gone. He was now fighting in the open, with the wetness of blood all around him.

His eyes blurred.

Not because he was unfocused, but he was hyper-focused on only the motion he picked.

Be it an attack from the pawns that mostly took the shape of a shadowy snake or even the knights that took the shape of a humanoid snake monster—with six arms, Rex did not differentiate. All motions his eyes caught are automatically assumed as an attack on him.

“Hrggh!”

Slash!

Rex sliced five pawns with the Red Dawn of Kaiser mid-air, severing their heads cleanly.

Another notification appeared, but it had become background decoration.

He was no longer counting the kills.

All his senses were focused on the heartbeats, changes in motion, and the gnarly scent of monsters.

Rex scanned the area and immediately made a leap, killing three more monsters by crushing their skulls before leaping away. He landed right in front of the voidal monsters that managed to go through him and immediately resumed the slaughter again.

No end to them.

His mind reeled as more stat windows kept on appearing from a distance.

More and more voidal monsters rushed in, akin to an endless black water tsunami.

Rex glanced over his shoulder in between attacks and found that Ethan was still helping the soldiers.

And worse, the other half of the voidal monsters that were clashing against Haxel’s side began to drift to his side. It was supposed to be good since their aim wasn’t to obliterate the horde, but to lead them to follow the White Mask.

But with the soldiers from Rex’s side still disoriented, they weren’t ready.

Some of the voidal monsters would stumble towards them, and casualties would build.

I can’t handle their numbers, and my stamina is rapidly draining.

Despite his efforts, he couldn’t keep up with their numbers.

He couldn’t use too much of the Inevitable Death Spirit Genesis, and he also doesn’t have any abilities that could cover a wide range of area. If he could access his elements in this realm, he’d have his lightning, but it was hard to hold back the horde without it.

Not to mention, he’s only stalling, too. He wanted to overwhelm me and make me of my powers.

Rex’s eyes were fixed on Haxel, who was commanding his soldiers to remain steadfast.

No sign of reinforcement from him.

It was clear that Haxel was going to let Rex and the soldiers suffer to gain an edge.

Just then, Rex’s crimson eyes flickered with an idea that made him grin deviously.

On the other hand, April unsheathed her nodachi when she realized the horde was now charging straight at the soldiers in formation. She was standing behind the first line of impact, tasked to provide support when necessary.

But in the last minute, her eyes were locked onto Rex within the shrinking dark dome.

‘It was hard to see it back then,’ She thought inwardly, recalling the time when Rex fought with the real Singing Lady. ‘He was too far within the Black Rift that I can only see glimpses, but now… I’ve never seen him in a real battle so closely, and I must say… he’s fighting so fiercely.’

April’s eyes shimmered with something as her grip on her nodachi tightened.

In her eyes, Rex was moving extremely fast.

He cleaved through five monsters with a single sweeping strike, then vanished in a blur—reappearing fifteen meters away to cut down a Voidal Knight slipping past his guard line, and then, without a pause, he unleashed a crimson arc of life energy, scything through dozens of Voidal Pawns in its path.

All of that happened in less than two seconds.

Rex’s quickness and reaction were off the charts, almost like he has eyes on the back of his head.

Despite possessing no effective ability to hold back the horde, he was still a formidable defense line.

‘He’s a technical fighter. I know of his combat skills more than anyone,’ April through, eyes narrowing as she focused on Rex’s movements. ‘But in a real battle, he didn’t fight technically with his superior skills. He’s fighting without any restraint to a specific martial art…. like an animal.’

Snapping from her daze, she noticed that the situation was getting dire.

More and more voidal monsters are sliding toward the disoriented soldiers on the other side.

Soon enough, the Seeker Flare would break, and casualties would climb.

“Sir Haxel,” April turned to Haxel beside him, who was commanding the soldiers under him, still not engaging in the battle himself. “Aren’t we going to help them? If we keep standing our ground, we’re going to sacrifice their side.”

“My concern is my side only. As for that side… It’s Sir Rex’s concern.” Haxel replied nonchalantly.

Even though they were supposed to be a team, he has no intention of helping.

“Berserker of Skartold!!”

Just as April was about to argue, an authoritative, baritone voice reverberated through the air.

She could see Haxel’s expression shifting from nonchalance to surprise visibly.

It was Rex’s voice, she recognized it, but she didn’t know why Haxel seemed to be taken aback by it.

Slowly, Haxel turned to look at Rex, who was still battling against the horde like a one-man army.

He tore through monster after monster, but still had time to glance at Haxel.

“Going to cower behind iron walls like a coward?” Rex growled, catching a Voidal Knight mid-lunge—one hand on its upper jaw, the other on its lower. Just as its fangs neared his face, he turned to look at Haxel with a savage grin. “Your power should be ashamed of you—skulking like a tiny serpent when you should be roaring like a lion.”

Brutally, Rex forced the maw to spread open and tore the creature in half.

Each wet snap echoed like punctuation to his words.

Not stopping at that, Rex grabbed a humanoid monster by the neck a ripped its throat with his teeth.

“Show me what you got, little snake,” Rex said condescendingly with blood-coated teeth.

He was laughing, eyes wide with insanity.

April’s heart pounded inside her chest, surprised to see how wicked and scary Rex looked right now.

But she quickly shook her head as that wasn’t what was important.

‘Berserker of Skartold…? Is that his Echo?’ April thought, confused as to how Rex could even get that kind of information. Some people decided to try and hide their Echo, and Haxel was one of them. ‘Even so, that level of taunt shouldn’t be worki—’

April stopped mid-thought when she noticed Haxel was grinding his teeth.

Not that she could see him grinding his teeth, but she could hear it.

Haxel was wearing a helmet, but it failed to hide the anger he was feeling right now.

Clearly, Rex’s words got to him.

“Haah…”

A slow exhaled hiss cmae through Haxel’s mouth, and with it came a thin stream of red vapor—hot and unnatural, as if his very breath had been boiled in rage. His hair, already tousled from the black wind’s rush, began to lift and rippled violently.

But not from the wind, but from the raw energy churning beneath his skin.

Swoosh!

Then, without warning, his body convulsed with power.

His muscles surged, stretching against the confines of his armor as his frame grew more massive. Red-blood light poured into his eyes, drowing out their original hue until they blazed like twin suns soaked in fresh blood.

A sudden pulse radiated from his shoulder.

Even though the dense armor plating, April saw a mark seared into view.

It was ancient and angular, thrumming with power.

Life energy coursed from it like a second heart, pumping molten strength into every fiber of his being.

Rapidly, the veins coursing through Haxel’s body flared with a vivid, steaming red—an unnatural sheen that caught April’s eyes the moment it crept up his neck and bloomed across his face. It was as if molten magma surged beneath his skin, replacing blood with something far more burning.

Haxel didn’t answer Rex with words.

Instead, he bent his knees, then launched himself into the sky with a thunderous crack of stone.

April placed her arm over her face, shielding her from the rustling shockwave.

On the other hand, Haxel soared high above the battlefield, a looming silhouette that melded seamlessly with the darkness overhead. As he ascended, his arms stretched toward the heavens, and in response, his Soul Artifact took form.

A colossal greatsword forged from pure life energy materialized on his back.

Grabbing the hilt, the greatsword shimmered with heat and fury, responding to Haxel’s touch.

Like a starfall and with a chuckle in his throat, he descended.

“RAARGH!!”

Haxel let out a roar that split the air as he brought the greatsword down in a single, devastating arc.

CRACK!

His greatsword struck the ground like a falling star, shattering the earth beneath the impact—destructive cracks webbed outward in every direction, and a shockwave exploded through the horde. Dozens, if not a hundred, of Voidal Monsters were launched like ragdolls, and the unlucky ones nearest to the blast had their bodies obliterated outright.

A wide, circular clearing formed in the very heart of the horde.

Laughing to himself, Haxel stood at the center of the crater he’d made, the greatsword still stabbing the ground and humming with crimson energy. Steam rose off his skin like smoke from a freshly forged blade as he turned to look at Rex thirty meters to his left.

“Challenge accepted,” Haxel growled, his eyes igniting with the same unhinged fire that burned in Rex’s. “I’ll give you a taste of Skartold’s Berserker.”

Rex bared his fangs in a savage grin. “And I’ll show you the wolf monster many feared.”

Boom!

Haxel grabbed the oversized greatsword with one hand and swung it in a circular arc, decimating more of the Voidal Pawns and also Knights that stood in its track. He didn’t stop there and kept swinging his greatsword wildly.

Each strike he made was a wide swing, backed with power, causing immense destruction.

Not even a collective effort from five Voidal Knights could stop the cleave.

On the other side, Rex also moved even faster, hacking the Voidal Monster one by one with precision.

His claws struck efficiently on their vital points, killing them almost instantly.

Haxel showed the might of a berserker, while Rex hunted his prey like an efficient hunter.

Under their collective effort, the pressure on the soldiers lessened greatly as the horde was scattered at the center. Only a few of them could brush past the rampaging Rex and Haxel, while the others were slaughtered like pigs.

Both were so immersed that even when the soldiers from Rex’s side recovered, they didn’t stop.

Rex and Haxel were drowned in the passion of blood, killing blindly left and right.

For a moment, the two of them forgot about their mission.

But then again, with the horde seemingly unending, the two of them could dwell in their bloodlust.

Until the tail of the horde could be seen, both of them were allowed to be blood-drunk.

April, on the other hand, watched from afar as the two slaughtered the Voidal Monsters brutally. It wasn’t entirely a foreign sight to her, but what stunned her was the big smile on Rex’s face.

He was having the time of his life—almost as if he took pleasure in committing slaughter like this.

Unconsciously, April clenched the hilt of her nodachi.

“Is this your real self…?”
