The Invincible Full-Moon System

In the extreme heat of the battle, Devo was spreading his arms to the side.

A violent torrent of spirit energy, boasting the accumulation of living for 30,000 years, exploded from his body. Simultaneously, his hands were entrapped inside a lightning bubble that was sucking as much lightning mana as possible to infuse the rain and turned the droplets black.

A sight that surprised Adhara. She saw Devo’s energy shooting up into the sky.

‘Compared to my spirit, his spirit energy is incredibly dense…’

Adhara might not recognize this attack, as it has been a long time since Rex used it. However, Evelyn or the other 25 Golden Crest descendants would recognize this instantly as the attack he used to obliterate the horde of mutated animals in the canyon.

Many Rastrikan Demons tried to get close, but they were unable to get relatively close.

It was due to a black lightning barrier that blocked them.

None of them realized that the black rain left a mark on them due to the adrenaline of the battle, however, there was a couple that realized this and tried to get rid of the mark forcefully using their demonic energy knowing that it was not a good thing.

But it was a futile attempt of them.

Disarming the mark was completely out of their reach, it stubbornly stayed on their skin.

Just like back then, Devo focuses for a brief second to wave his hand, disarming the mark that was imprinted on friendly forces. It was only when he finished that Rex pointed both of his hands to the sky, preparing to launch a powerful spell.

‘What is he doing? Aren’t we supposed to hold back until the formation is finished?’

Adhara who was watching this from the sight frowned.

In order to not alert the other legions, the plan involved the Elves creating a formation bubble to act as a cocoon that could contain the rampaging energies. Since the Elves were faster at magic and rune engraving, they were tasked with this responsibility.

But seeing Rex this blatant, it doesn’t seem like he was holding back.

“Seems the Elves already did their job, I didn’t realize it because the formation is quite subtle. Did the Elves know a way to mask formations? Or was it Lord Rex’s doings?” Huvuki mused inwardly, finding that the formation was already established.

Upon hearing this, Adhara was also surprised slightly as she didn’t sense the formation.

‘Right… I thought he was swept by the battle. But it seems he was not’

Rex said that he wanted to let out some steam, and that made her think this way.

However, she didn’t give Rex much credit knowing that his mind is most of the time composed, and he wouldn’t be that reckless, especially when the plan to take out the Rastrikan Demons involved defeating Demon Lord Ranath and his legion silently.

Maybe I should go all out, he would definitely try to stop me.

Gazing at Demon Lord Ranath who has recovered, he fixed his mind on going all out.

“Symbol of Lightning…”

Blitz!

Rex whispered softly through his lips, casting the new spell that he gained.

In an instant, the violent black lightning around his body intensified, becoming even more chaotic. Even the pressure emanating from it claimed to a frightening level, and a circular glow appeared on his chest, a second spirit core.

Since this is a big-scale fight, he would need to rely on his lightning elements more.

Upon seeing this, Demon Lord Ranath scoffed.

Roar!

Demon Lord Ranath unleashed another soundwave, which seemed to energize the Rastrikan Demons with demonic energy even further, and then charged forward, intent on interrupting whatever spell Rex was in the midst of casting.

Propelling himself with hellfire, he managed to reach Rex in a couple of seconds.

Like searing lava, the lightning barrier proved to be utterly inefficient against his charge, allowing him to penetrate it effortlessly. Even the black lightning attempting to strike him failed to have any effect, it doesn’t seem to faze him.

Seeing the black lightning travel through his skin before dissipating, Rex frowned.

Hmm…? Is he immune to lightning?

Rex suspects that Demon Lord Ranath is immune to lightning, the way the black lightning interacts with his armor-like skin is unnatural. It was then he glanced over at the other Rastrikan Demons fearing that they too are immune to lighting.

But thankfully, the other Rastrikan Demons don’t seem to be immune.

Kaboom!

Demon Lord Ranath swung down at Rex with his blade arms in full force.

<Wicked entity detected!>

<The user has suffered more damage due to the Infernal Weakening of the Abaddon effect!>

A vicious explosion was created as Rex blocked the attack with his sword and got pinned on the ground, he coughed a mouthful of blood but was still smiling in exhilaration. “Surely you don’t expect me to let you cast your spells? I would be a fool if I did” Demon Lord Ranath commented with a nasty grin.

“I kind of expected you’d come for me” Rex replied, a smirk plastered on his face.

Upon seeing this confident smirk, Demon Lord Ranath frowns.

Just then he realized that the ground was flooding, he didn’t realize when it started to flood, but he knew that this was definitely Rex’s doings, seeing that he was smirking from ear to ear at his realization.

“Come on, old spirit! Now!”

Moving fairly quickly, Demon Lord Ranath wanted to grab Devo but he was far too late.

Devo already flew to the sky and became an eye of lightning.

Rumble!

It was then the entire battlefield began to shake, and all within it gazed up when a thunderous rumbling sound permeated through the air. Compared to the normal entities, the Rastrikan Demons that saw this phenomenon growled towards the sky fiercely, having no sign of fear.

Under the guidance of Devo’s spirit energy and lightning mana, the sky obediently listened.

“Great Lightning Spell, Sky Rupture Assortment!”

Since Rex and Devo were connected, their powers were identical in the lightning element department. And upon chanting that, the entire sky flashed brightly, as if the gates of heaven had opened for a fraction of a second.

Following that were hundreds of small dots, firing black lightning strikes viciously.

A sudden silence enveloped the entire battlefield.

But in the next second, a ringing sound strikes their ears and impaired their hearing.

CRACK!

KABOOM!

Rex watches this with a huge smile, however, Demon Lord Ranath moves even faster in response and draws upon his demonic energy to completely cover the sky with a shield of hellfire that stands in the way of the black lightning strikes.

Despite this move, Rex doesn’t seem to be surprised.

I played it safe, knowing that he might be able to block this spell. And that comes to fruition.

Knowing that he was fighting a Demon Lord of the most vicious and brutal force, he decided to purchase a spell from the System called Flooding Area. As the name suggested, it created a flood in an entire area.

All he needs is one black lightning strike to go past Demon Lord Ranath’s defense.

No matter what, Rex believed that at least one would pass through.

Oh, there it is…

Upon seeing a single black lightning strike burst through the hellfire shield, Rex smiled as the black lightning strike electrocuted one of the Rastrikan Demons completely, scorching its nerves and everything inside its body.

<Rastrikan Demons killed: 1>

Moreover, the black lightning travels through the flood and spreads around the area.

It also seemed to be getting stronger instead of getting weaker.

This was precisely why Rex chose the Grey Water of Radiant element as his water element over anything else. It has an amplifying energy, a property that could make most elements that were infused with it stronger.

Just like that, the marked Rastrikan Demons got struck and suffered the same fate.

<Rastrikan Demons killed: 7>

<Rastrikan Demons killed: 41>

<Rastrikan Demons killed: 119>

<Rastrikan Demons…>

Notifications from the System keep on coming out as the Rastrikan Demons that got hit by his black lightning died, the combination of the Sky Rupture Assortment and Flooding Area is too much for them to handle.

Despite their rigorous vitality, they fell one by one by the bouncing black lightning.

“Do you actually care for your legion? I’m surprised, Demon Lord Ranath” Rex stood up from the ground, tilting his head and commenting descendingly. “Be careful now… If I know your weakness, then helping you feel fear would not be a challenge for me” He grinned.

Finding that Demon Lord Ranath looked back at the other demons, it seemed like he cared.

Upon hearing this, Demon Lord Ranath smiled savagely.

“Care…? Don’t get cocky in front of me”

Crack!

Turning around with a powerful stomp, a pulse of demonic energy came out.

One stomp is all it takes for Demon Lord Ranath to cancel the Flooding Area spell and dissipate Rex’s spells with relative ease, and the mark, a combination of the Wrath and Envy symbols on the center of his chest glowed with a chilling energy.

Almost as if something inside of him was awakening, something horrifying and wicked in the core.

It was then his eyes fixed onto Rex maniacally.

Demon Lord Ranath’s energy turned into an imposing mountain, cracking the ground around.

Similarly, his blade arms, oozing with reddish demonic energy started to slowly shift from crimson to eerie black. A sudden change that could be felt by anyone on the battlefield almost instantly.

Rex was no exception, he could sense his senses were alerting him of a powerful entity.

With a slow movement, Demon Lord Ranath then gets into his battle position.

Crossing both of his blade arms in front of him forming an ‘X’, he concentrated all of his demonic energy into them while keeping intense eye contact with Rex. It was then that his body disappeared into a blur.

Demon Lord Ranath moved faster than Rex’s eyes could perceive.

SWOOSH!

Like a rampaging star fire, the furious Demon Lord Ranath closed the distance between them in an instant, catching Rex off-guard as his speed increased exponentially. It was so fast that he couldn’t even glance in time at Demon Lord Ranath.

Slash!

Spurt!

Rex’s eyes widened when he felt a sharp excruciating pain in his right arm.

Blinking rapidly for a second, he shifted his gaze to his right arm and found it was severed, blood gushing from his wound. His right arm hung in mid-air, alongside the daunting crimson arc, with Demon Lord Ranath standing low directly before him.

His demonic eyes flashed as this definitely would be the turning point of his victory.

It’s all the same, his recipe for victory always remained the same.

‘Even the strongest I’ve fought would be distracted I caught them by surprise like this, and everything will start to go my way starting from there. Powerhouse of the new era? I’ll show you the might of the ancient era’ Demon Lord Ranath pondered with a maniacal grin.

Nothing would be stopping him from his victory now.

Since the demonic energy he infused in that attack is also thick, Rex will definitely be put off.

However, in the next second, Demon Lord Ranath widened his eyes.

Slash!

Contrary to his expectations, the pain of having his arm severed and the demonic energy infiltrating his body doesn’t seem to put him off. Rex grabbed his severed right arm that was holding the Silver Eye with his left hand and swung it at Demon Lord Ranath.

Inside his slashing motion was the red force and also the Executor Slash skill.

“Hmm…?!”

Demon Lord Ranath widened his eyes when he saw his own right arm also got severed.

It seems he was wrong to assume that Rex would be thrown off of his game, he wasn’t. Instead, he seemed to be even more excited judging from his smirk and the peculiar spark in his battle-hungry red eyes. 𝞸𝑣𝑙𝐞xt.𝗰𝑶𝑚

Thanks to the holy energy cloaking the Silver Eye, it sliced through rather easily.

Upon realizing what had just happened, Demon Lord Ranath also smiled and his eyes flashed with the same light as Rex. At that moment, the two realized that they were as maniacal as the other, and their blood boils in desire for wanting to out-maniac the other.

On the inside, Rex was laughing heartily, finding solace in this painful feeling.

Yes, this is what I wanted! Let’s dance more! Let’s try killing each other more! Let me feel alive! I’ll vent it all to you!
