The Invincible Full-Moon System

Swish!

Aside from the molten blue and red lava that are splashing out of the ground from the outburst of energy, the blue flames that were left behind by the Blue Demons that got extinguished completely sizzles and swayed by the hot air.

Rex is standing in the middle of it like a battle God that has killed countless enemies.

In that little timeframe that he used in creating chaos on the backline of the Supernatural army, at the very least a third of them got wiped out of existence. Most of them are unable to get near Rex who has activated the Alpha Bearing skill.

Not only that but his ninth-rank energy also turned the weaker ones to ash.

At the very least only the seventh-rank realm Blue Demons and Succubus inside a mile radius can sustain that sudden outburst of kingly energy, the others weaker than that and that are also too close got wiped out.

But out of nowhere, the sways of the blue fire around him become unnatural.

Rex noticed this occurrence before the eighth-rank Blue Winged Demons hold Rex's arm each, their demonic faces were covered by black charcoal skin and they glared at him while protruding their flaming tongues nastily, "Forfeit your life and King Saruth will save you from the torture of hellish flames..."

"Nothing in your life is worth living for, Werewolf Prince. Eternal doom awaits you..."

Each of the Blue Winged Demons said their lines with a slight cackle coming out of their mouths. On top of that, their voice was like the astral soothing voice of Satan trying to convince him to kill himself.

Upon hearing this Rex looks down to the ground with a dark expression.

Despite already noticing the weird sway of the blue flames earlier, it seems he deliberately lets himself get caught like this. With their demonic energy gathered in their arms, Rex can feel the burning sensation piercing his arms.

If he were any weaker than his arms would probably melt by now due to the demonic energy.

"What would my death serve...?", Rex mutters lightly while still looking down.

Although they were not expecting this the two eighth-rank realms Blue Winged Demons smiled mischievously as they looked at each other, it seems their incitement reaches the tip of Rex's heart.

Looking back at Rex, one of them then said, "Savior of the Supernaturals..."

"Your inevitable death would turn you into the Savior of the Supernaturals. Regardless of your contemplation of race, you are one of us. It's your duty to be our Savior, follow your fate and surrender to death", it added trying to push Rex further into the edge.

But upon hearing this, Rex smiled in ridicule, "Supernaturals, humans, all of you can go to hell"

From the start, he deliberately lets these Blue Demons give their all against him. Rex is still thinking about the fear that these Supernaturals are emitting, he needed to know what was that about and also why they are this desperate in trying to kill him.

It's clear that there's something more than meets the eye, and now he got a glimpse of the answer.

Just from hearing the two Blue Winged Demons alone, Rex can already tell that his death would benefit the entire Supernatural race. At first, he thought that they fear of his rapid progression, but it seems that is not the only case.

The Supernaturals' desperation is thick here, so there must be more reason than just that.

"If that is your choice Werewolf Prince, then so be it. We will force you to accept your fate in the name of the Vulvazith Ruler", the Blue Winged Demon replied before they both turns into blue flames and pulls Rex into the ground.

Rex was surprised as half of his body got embedded into the ground.

Upon being pulled down onto the ground his body got the full brunt of the blue and red lava that are residing inside this hellish plain, countless whips also wrapped around his arms from the succubus around him, trying to pin him in place.

But in the next second his eyes dilated feeling something probing his soul with a cold grip.

Slowly his consciousness was pulled into a different dimension, where everything turns shadowy.

Blinking his eyes a couple of times Rex saw that two red shadowy souls in the shape of a seductive succubus is already holding his soul, their sharp claws are already grazing his soul without any resistance whatsoever.

It surprised him to see that there was such a place in existence, the Dimension of Souls.

Out of nowhere as the two souls of succubuses are grazing his innocent souls with their claws, Rex can feel something burning on his chest. Looking down he can see that it was a necklace that he recognized almost instantly, 'Whiro Necklace of Despair is reacting?', he thought in surprise.

Remembering that Whiro Necklace of Despair has soul ability, Rex's surprise didn't last long.

Not long after the two souls of succubus latch themselves onto Rex's pale white soul, the Whiro Neckalce of Despair burns even brighter as it dyed Rex's entire soul with the color red. Immediately after that, the two souls of the succubuses wail and cry in pain.

From the plain of reality, Rex's eyes seem to roll to the back under a spell.

Above his body were two succubus with pinkish skin and their vital part covered by black charcoal armor, their devil tails glowing and so does their eyes as they cast a mix of mind and soul spell that can even bypass the Anti-soul passive skill Rex had.

Both of them are distracting Rex to create a chance to land a powerful attack.

On the other side of the place the snake-like Blue Demons already merged together turning into a two-headed Blue Demon Snake, they are channeling a devastating amount of demonic energy that even creates pulsating inward waves to its body.

It makes its body more robust and stronger, it can't help but roar powerfully.

Roar!

Soon enough a circle formation with demonic writings inside appeared right in front of Rex's chest which was created by the two-headed Blue Demon Snake. After the formation matured completely, the two-headed Blue Demon Snake then slithers very fast, turning into a gigantic size bullet that turns smaller and smaller.

As it got closer, the two eighth-rank realm succubus suddenly wail in pain.

"W-What is this fire?! How can it damage my body!!", the succubus cried out while looking at its own two hands that doesn't look different, but the burning sensation makes it feels like its entire body is melting.

It takes the two succubus a moment to realize that their souls are the ones on fire.

Just from touching Rex's soul briefly, they got a blowback so devastating that their spells were canceled instantly. At that moment they realized that there was a necklace reacting to them, but it wasn't the one that caused this burning sensation.

The necklace only creates a chance for Rex's soul to express itself completely.

What burns the two succubus was the wrath burning inside Rex that has turned even greater compared to before, it was so hot that even a succubus that should be quite resistant to fire feels its entire body burning.

Rex then snapped out of the Dimension of Souls but his eyes widened seeing the incoming attack.

KABOOM!

"Haahkk!"

Surprisingly, Rex feels the wing gets pushed out of his lungs upon getting hit by the demonic bullet the size of himself right at his chest, it was the first time feeling pain since the battle has started. It was completely baffling.

But looking at the two-headed Blue Demon Snake, it's clear that the attack was not a normal one.

Gritting his sharp fangs while looking at the Blue Demon Snake's core in its chest, Rex realized that it burned 99% of its life source just to do that. If not for that then it doesn't have any chance to do anything to Rex.

Coughing ash a couple of times, the two-headed Blue Demon Snake smiled.

"We demons embrace our demon energy to the fullest extent, using it and harnessing its strength. But you... you're a Werewolf and yet you're using a weapon. What's wrong? Are your claws blunt from living with the humans?", it said mockingly before hissing in ridicule.

For some reason, Rex was ignited by this and he feels a little bit angry.

Despite still being embedded inside the ground with the two Blue Winged Demons holding his legs inside the lave beneath the ground, Rex slowly raises his gaze to meet with the two-headed Blue Demon Snake before he suddenly jumped out of the ground.

Crash!

Putting away the Amuerus Katana into the inventory, Rex grabbed the demon with his claws.

With most of its life source burnt in that attack it did from before, the two-headed Blue Demon Snake can't put up any resistance at all as its body wrapped around Rex's arm but failed in doing anything to it.

Rex pulls both of the heads closer to him as his eyes glow with red, influenced by his kingly energy.

"For a dead demon, you talk too much..."

Instantly after he said that Rex gripped both of the necks tighter before he split the two-headed Blue Demon Snake's body in half before it shattered into dust. But swiftly after that, the two Blue Winged Demon sprawl out from the lava once again intending to attack Rex.

But Rex has done playing around, he already gets a little out of them.

Cloaking his arm with his kingly energy, Rex backhanded one of the Blue Wing Demons sending it crashing away while he grabbed the other by the neck. It was done with one slick motion before Rex jabbed his claws into the Blue Wing Demon's back.

Splash!

Despite being a demon, the Blue Winged Demon shows signs of pain.

Grabbing the spine of the Blue Winged Demon, Rex literally peel it out of its body until the spine alongside its skull got separated from the rest of its body. Such a gory scene but demons don't have blood, so Rex's furs are not stained by that filth.

After doing that he jumped to the sky before more Succubus and Blue Demons attacked him.

While he was looking down on the army of Supernaturals that are already lessened considerably, his eyes then landed on King Baralt, Queen Catsha, and Azzen watching from afar, not moving even a muscle.

Out of the three, King Baralt seems already impatient. Rex cans see it clearly in his twitching face.

Knowing that he needed to take their attention so that the others can even hope to survive this ordeal, Rex roared while bearing his kingly aura without holding back, "KING BARALT! Come fight me! Let's see who's the real King of Werewolves!!", Rex shouted tauntingly.

Upon hearing this King Baralt started circulating his own kingly energy with a daunting look.

Easily provoked like a monster that's trying to find a reason to fight, King Baralt instantly replied with an ear-shattering roar as his kingly energy shoot into the sky, "I ACCEPT YOUR CHALLENGE ROYAL BLACK PRINCE!! Let not the Origin but ourselves decide who's the real King of Werewolves!!"

Without even wasting any second, King Baralt leaped straight at Rex in the sky.

"King Baralt! Wait!! He must still have some tricks up his sleeves!", Queen Catsha shouted but ignored, she can only curse the barbaric impulse of a Werewolf that has its pride at the very top of its head.

Azzen on the side waves his hand, "Don't even bother stopping him..."

"We'll just watch and see what kind of power this Royal Black Prince is hiding, I have a feeling that he's still hiding most of his powers. Fighting King Baralt would definitely force his hands to use them, and you'll strike when we have enough information about his power", he added calmly.

Even though it was Azzen that is talking, Queen Catsha knows that Azzen is not usually like this.

Since she knows exactly what Azzen is due to her being a part of the Demon race before, Queen Catsha realized that it was not Azzen that is talking, it was King Saruth instead that used Azzen's body to communicate.

"What are you going to do if not helping King Baralt fight the Prince?", she asked with a frown.

Upon hearing this Azzen's blue flaming eyes glance at Queen Catsha before he shifted to Adhara, Flunra, and Gistella fighting at the frontline, "Me? I'm going to go and have a little bit of fun with the Betas of the so-called Royal Black Prince..."
