The Invincible Full-Moon System

"Step aside and live, or die", Rex said full of killing intent.

A subtle shockwave exploded from Rex's body making the winged demon frown, the winged demon can feel the sudden change in Rex's body.

"You...", he mutters in disbelief,

But the winged demon's disbelief look turns into a smirk, "They said you're a king, but now I see that it's just a fluke"

"King Saruth is right, there's no way a king is inside human's territory. Thank you for enlightening us", He added.

Hearing this, Rex looks at the winged demon in confusion.

He then realizes something, 'That shapeshifter told them?! I should've known, but what did he mean by that?', Rex thought.

The Shapeshifter that attacked him during the Faraday University tournament is still hasn't been caught, and it somehow told the Supernatural about its meeting with Rex.

That night, Rex activates his invincible item that makes his body glow red.

It startled the Shapeshifter and Rex intimidate the shapeshifter until it run away with the help of the Invincible item.

"Whether it's a fluke or not, I can still kill you", said Rex as he emits a white hue.

The moonlight enhanced 50% of his stats thanks to his Creature of The Night passive skill, but it's still not enough to fight the winged demon in front of him.

"Pure Brace of Moonlight"

Swooshh!!

After the white hue, Rex's body got enhanced once again with the yellow force.

White and yellow energy intertwines with each other as Rex's stats got enhanced once again, it makes Rex's body emits a different and more violent aura.

The winged demon frown as he felt Rex's aura becomes stronger and stronger.

It's not an exaggeration that Rex's aura is now as strong as him,

But instead of fear, the winged demon smirks as if he's not threatened by Rex at all.

Rex felt something is a miss before he signal to Delta on his side,

Delta growls towards the winged demon, she slowly walks back while maintaining eye contact before she runs in the opposite direction.

After Delta left, Rex gets into his battle position as he glances to the side.

Besides the winged demon that is focusing his attention on Rex, he saw Kyran already got there and is currently taking the rubble off of Adhara's father.

"You're fighting me alone? I don't mind fighting you both", the winged demon said pridefully.

Rex can only chuckle mockingly, "It's going to look bad now if you die"

The winged demon laughs back but then he notices Rex looking at his side, but just when he wanted to look at his side,

BOOM!

Rex's aura exploded as the ground cracked from the pressure, his eyes becomes crazed as his legs muscles bulged before he dash towards the winged demon.

SWOOSH!

Looking at this, the winged demon's body burns with blue fire as they clash with each other.

CLANG!!

The steel plate of his black devil gloves clashes with the winged demon's claw, it sparks with energy as they both stares at each other with a devious smile.

"RAARGH!", The winged demon roared as he pushes Rex backward.

Rex got flung away but his body started blitzing with black lightning, upon landing his body instantly vanishes.

He turns into a lightning current as he appeared in front of the winged demon.

Both of them exchange blows after blows creating a vortex of shockwaves, it destroyed the houses and buildings in the surrounding in the process.

The winged demon was quite shocked upon seeing a tattoo appeared on Rex's wrist,

The tattoo manages to weaken his blue fire, it makes his blue fire bearable for Rex who has a strong regenerative ability.

SLASH!

Rex manages to slash the winged demon's abdomen using his claws,

He turns his fingernails into claws whenever he attacks and turns them back into fingernails to avoid the watching eyes in his surroundings.

And he smiles when he manages to land a slash through, but then,

BAM!!

Rex cannot pull his claws out before the winged demon hits him with its claws.

BOOM!

The hit send Rex flying to the side like a jet as he crashed onto buildings and destroyed them, he stopped after stabbing his claws to the ground.

"Kuakh!", Blood gushed out of his mouth feeling the power behind the punch,

But before he can properly recover, he senses something coming at him.

Rex somersaulted in the air as he dodge the winged demon attack, his leg then suddenly glows with a yellow hue, "Force Beam!"

BAM!!

The kick landed directly on the winged demon's face, the winged demon got sent crashing away.

Although the fight is fierce, there's an evident smile on Rex's face even though his black uniform got tattered here and there with blood leaking out of it.

Rex then dashes towards the winged demon, his legs look blurry,

He glance towards Kyran's direction and saw that he's already gone, this means that Kyran manage to take Adhara's father away.

But then suddenly,

The winged demon suddenly planted his hands on the ground, he opened his huge mouth wide open as blue fire gathers in his mouth.

From just a glance, Rex can feel the huge amount of energy on the winged demon's mouth.

"With this, you die!", the winged demon shouted.

BOOM!!

A thick energy blast made of blue fire exploded from his mouth, it makes the ground trembles as the energy blast destroyed everything on its path.

Rex's pupil widened as he saw the energy blast,

He didn't have the time to dodge it because of his momentum, he wrecked his head for a fast solution as the energy blast hits him.

KABOOM!!

The energy blast exploded destroying everything in their surrounding.

All of the four-armed demons in the surrounding or even humans got propelled away because of the destructive shockwaves.

The city walls got destroyed again,

Its remains crumble exposing the city like a naked woman, anyone can see the city now from the front because of the destroyed wall.

Black smoke covered the surroundings because of the explosion,

The winged demon then stands back up while cracking his body, "I'll report this incident, the Alpha Werewolf of humanity has died"

But then suddenly, "Hmm?"

The winged demon frown when he suddenly felt uneasy,

He looked at his hand and find it trembling, his feeling also becomes nervous all of a sudden as if he's standing in front of a king.

GRAB!!

Out of nowhere, a big hand grabbed his face as he got slammed on the ground.

The winged demon was surprised and confused at the same time, he looks at the one who slammed him on the ground in shock.

In front of the winged demon,

Rex is staring straight into his eyes with immense killing intent, his eyes glow red as he stares at the winged demon with a death glare.

But what surprised the winged demon is not that Rex is alive, but he's in his Werewolf form!

Rex's body is now almost as big as the winged demon, his black furs are darker than night, and his horns that curve back and down shocks the winged demon to his core.

"Prince?!!", the winged demon shouted with a muffled voice.

The realization of Rex's Werewolf form greatly shocks him, it can clearly be seen in his face.

Hearing this, Rex frowns, 'Why is this demon shocked with my appearance, and why did this demon call me prince?'

Rex pins the demon on the ground with his right hand,

The smoke still covered the surroundings and he can use this to transform without anyone noticing, but he can't stay in this form for long.

Rex gripped the winged demon's face tighter, "Why did the demons decide to attack?"

"I'm not going to answer your question", said the winged demon stubbornly.

Hearing his, Rex smiles brutally, "I'm sorry, you thought that was a question huh?"

STAB!

"RAARGHH!!", the winged demon shouted in pain as his abdomen got stabbed by Rex's sharp claws, it pierced through easily until the back.

"Tell me right now or I will ki-", before Rex can finish,

The winged demons intervene, "Or you will kill me?", he laughs loudly.

"We are sent here to die, so I'm not afraid of your little threat little Werewolf Prince", the winged demon continues mockingly.

This makes Rex frowns, but then suddenly,

CRACK!!

Rex looks to the surroundings and finds the smoke was about to disappear, and the ground suddenly cracked and a blue fire emits from below.

'This is exactly like Benrith City', Rex thought with a frown.

When his train got attacked, the ground there is filled with demonic energy and fighting against the demons becomes two times harder.

And now this happened to Beah City too,

SLASH!

SLASH!

Rex cut all of the winged demon's limbs in anger,

The winged demons cried out in pain but Rex didn't care, he brutally severed the winged demon's limbs as the wounds emit an intense black smoke.

After doing that, Rex's body transforms to normal.

He looks around trying to find Kyran and the others, but it seems they already left the city.

The city already becomes quiet because of their fight, but the building in the center of the city lit up in blue fire.

Rex frowns looking at this, 'I send Delta to help rescue the humans, and Edward probably helped the humans too so they must be outside'

Even though Rex's face is trying to hide it, the winged demons notice it clearly.

Rex's left arm is hurt because of the energy blast from before, and it seems that it started to regenerate slowly.

"I'm going to watch as your expression turns into agony!", the winged demon said.

This makes Rex looks back at the limbless winged demon, "I'm going to kill you right now, tell me why or I'll send you back to hell"

Hearing this, the winged demon smiles but then,

TAP!

BOOM!

Rex looks up and saw two figures flying in the sky, their movement surpassed the sound barrier as they went in Benrith City's direction.

'Is that the high-rank reinforcement?', Rex thought.

Vargas' secretary, Linda told him about the reinforcement from the border will help.

But then, the winged demon suddenly said, "It's too late"

"What do you mean by that?", Rex asks with a frown, the way the winged demon is acting makes him feel something is wrong.

BOOM!!

Blue energy suddenly shot up to the sky from Benrith City,

And not long after that, another blue energy shot up to the sky from Lupis City's direction.

It makes Rex's heart filled with uneasiness,

'System, Do you know what that blue energy is?', Rex asks, but the system didn't answer, and this makes Rex become even more uneasy.

"Since it's too late, do you want to know what that is?", the winged demon said with an amused and creepy smile.

Rex walks towards the winged demon before he pressed the winged demon's chest with his feet, "Speak now!!", Rex shouted in anger.

The winged demon coughs weakly but the smile is still there,

"Do you know where that two powerful humans came from?", the winged demon asks.

Hearing this, Rex frowns in thought, 'Did he means the reinforcement? they're from the Great Barricade'

But then, Rex suddenly realizes as his face drains from all color.

Looking at this, the winged demon laughs loudly exposing his razor-sharp teeth, "You get it now? Watch as humanity burn"

Without wasting another second, Rex killed the winged demon in anger.

SLASH!!

He cuts off the winged demon's head in one slash before he takes his phone and dialed a number, the phone rang a couple of times but it didn't get answered.

Rex then dashes out of Beah City, he saw Benrith City on the edge of his vision.

The demonic aura coming from that city is very powerful but now he realizes, it's all a fluke just what the dead winged demon said.

'That's why he said thank you! FUCK!!', Rex screamed in his head.

Based on what the winged demon said, the plan is to lure the powerful Awakened from the Great Barricade by using these demonic cities.

The demonic cities emit a very powerful aura, but it was all just a fluke just like the Invincible item.

Rex looks at Benrith City and can feel the Awakened is fighting, he wanted to dash there to warn them of the demon's plan but his phone suddenly rings.

He then immediately answered it, "Rex? Are you okay?", Vargas asked.

"CALL BACK THE AWAKENED ATTACKING BENRITH AND LUPIS CITY!", Rex shouted on the phone.

Hearing this, Vargas frowns, "What do you mean?"

"THE SUPERNATURAL WILL BE ATTACKING THE GREAT BARRICADE!!"

~

The Great Barricade,

A man wearing a military uniform asks as he found a weird flying object on his computer, "What's that? Tell the watcher to scan that thing"

"Wait...", a military went outside and look at the flying object.

Just as he tried to identify the flying object, he realized that it was a creature, not an object.

But then suddenly,

SWOOSH!!

An immense blood aura suddenly exploded from the flying creature's direction, and this makes the military man widen his eyes in shock, "VAMPIRES!! That's a King!!"

In another part of Great Barricade,

BOOM!

BOOM!

Four Demon Hives suddenly fall from the sky just a couple of miles from the great barricade, this instantly alerts the military and the Awakened guarding the Great Barricade.

Many military men went into their posts prepared to defend the Great Barricade.

But then suddenly, the ground trembles which makes the humanity's side looks at their front in horror.

Thousands of Demons emerge from the horizon, and they're all charging straight towards the Great Barricade like an animal.

Then, a huge demon suddenly appeared.

This particular demon brought an overwhelming pressure just by standing still, and it raises a bastard sword filled with a demonic aura that makes the ground turns red.

From just this display, anyone will know who this demon is, King Saruth!!

King Saruth raises his sword with a devious smile on his face, he saw the two blue energy shooting to the sky as he shouted, "Charge my children!! We will take our first step in conquering humans!"

Three other powerful demons suddenly appeared beside King Saruth.

By their humanoid bodies and their powerful auras that resonated miles away show that they're all Archdemons.

"Let the Slaughter Begin!"
