The Invincible Full-Moon System

King Mark...

Any Werewolf would've instantly known the term, King Mark. It's the mark or sign of a Werewolf reaching the highest degree of the race hierarchy, it's the sign of strength, wisdom, and standing. Even the most-hated Werewolf would be respected and revered if it have King Mark.

Only the ones that are accepted can harness a King Mark, only Werewolves at the very top.

12 King Marks are recorded since ancient times revering to each Full Moon.

Out of the 12 King Marks that a particular Werewolf can hope or dream to achieve, four of them stand out as the ones stronger than the others. Blood Moon, Super Moon, Dark Moon, and Yule Moon. Time has recorded the might of these King Marks bearers.

With their variety of powers, they managed to earn the respect of the Supernatural Race.

Just like the Archdemons of the Demon Race, the Heavenly Dragonman of the Dragonman Race, the entities bearing King Mark are well respected in every land they stood on. It's the only thing that can unite the Werewolf race filled with resentment in this era.

King Baralt possesses a King Mark, and he's accepted as the King of the Scarlet Banes Kingdom.

If it weren't for the King Mark that shows that he's worthy of being the leader, King Baralt wouldn't be able to ascend to the throne rather easily. But with the King Mark at hand, everything went on smoothly.

Arnulf has been the guardian of the Dark Prince ever since the end of the Radical Era.

Being close with the Dark Prince he has the ultimate honor as a member of the Werewolf race, this of course leads to him knowing many things that regular Werewolves don't know about. Amongst others, he's the most aware of these King Marks.

Despite knowing it all, Arnulf can't believe what he was seeing right now.

Having personally seen the previous Royal Black Prince, Arnulf knows the power that possessing multiple King Marks is the trait of the Royal Black Prince. But even still, looking at the dual King Mark on Rex's forehead shocks him.

"This level of energy... it already reaches the mid or even peak of the tenth rank, impossible..."

With a clenched jaw, Arnulf is in a state of disbelief.

The word 'How' keep ringing inside his head like an unending bell that is being rung just beside his ears repeatedly, it was not possible to achieve this kind of state in such a short amount of time. Arnulf refused to believe it, but his eyes are convincing him.

"It's too fast, it shouldn't be possible! There's no sign of his acceptance too, this not right!"

Remembering that the previous Royal Black Prince needed a hundred years just to be accepted by two full moons, Arnulf doesn't want to believe what he was seeing. It's utter nonsense, but his senses hardened through the ancient years of his life have never failed him before.

It definitely won't fail him now, the energy coming from Rex is real. It surpasses the ninth rank.

Even Ian who was witnessing this happening with his own eyes widened his eyes in absolute terror, the power Rex emitted surpassed King Baralt's power which shouldn't be allowed at this time, "The world is not ready, but how can he reaches the tenth rank already?!"

Unknown to all of them, the demeanor of power was nothing but a facade.

Despite being a facade the energy coming from Rex's body is definitely real, the feeling of invincibility downs at him again caressing his ego to take on the whole world. If he possesses this kind of power, then he can definitely take down the entire world by himself.

It was simply intoxicating, and it was all because of one special item given by the system.

Invincible item...

Rex can gain this item only through completely a Berserk Quest, it's an item that can draw out the full potential of his body to the utmost limit disregarding any shackles that might bound him to achieve that state.

Having the Royal Black Prince bloodline, his potential limit is not the ninth-rank realm anymore.

Back when he used the Invincible item to save himself from the Shapeshifter that tries to want to kill him, the Invincible item also gives him the Blood Moon King Mark but it was maxed at the ninth-rank realm. Now that's not the case.

Without even needing to look at his forehead, Rex can feel to different energy coursing inside.

They were like two completely different energies that nourishes his body and filled it with power, and both energies worked perfectly along each other without any friction or restraint at all. It's a work of art, something that is devastatingly hard to achieve.

Rex doesn't know the process, but achieving this kind of harmony surely requires sacrifice.

It's only thanks to the Invincible Item that he can feel directly this kind of power, but just like the one before, this item is only a defensive mechanism given by the system. It's only able to block but not attack.

Although he was threatened by Ruston's advancement before, Rex has another plan in his mind.

Looking up to the fading Countess of the Dark Luniric being pulled away by the Black Shackle, Rex smirks confidently. With a flash of his fierce eyes, the steady stream sent by him to destroy the Black Shackle becomes even more powerful.

Despite not having any attack properties, the energy from the Invincible Item is real.

Rex has already thought of this in a fraction of a second when he saw Ruston lunging at him from behind, it's quick thinking of his and it seems it's going to work judging from the stream of energy getting thicker and more robust.

BOOM!!

Dark and Red Moonlight energy enters the stream of energy amplifying the density of the energy.

It travels lightning fast as it immediately imbued the Black Shackle with overflowing energy that even the Black Shackle can't contain properly, it started to heat up turning orange slowly from black.

Upon looking at this, Arnulf realized that the energy stream is too much for the Black Shackle.

"ROYAL BLACK PRINCE!! DON'T DO IT!! DON'T BREAK THE SHACKLE OF THE BANISHED COUNTESS!", with a desperate roar that reverberated to the surrounding, Arnulf tries to make Rex stop but his roar falls int deaf ears.

Rex didn't care about what he was saying one bit and just focus on the task at hand.

Out of nowhere, the Countess of the Dark Luniric started regaining her appearance with the Black Shackle losing its power from the powerful stream of energy that is equivalent to an energy beam of a tenth-rank realm being.

Just like a devil glancing down at a puny baby, Arnulf's throat went dry.

Even Ian and Ruston that doesn't experience it first-hand felt the overwhelming fear that they are feeling right now, the Countess looks down with her blackhole eyes at Arnulf but her expression now contains an emotion.

It was wrath, she bore anger towards Arnulf for activating the Black Shackle.

"We'll retreat! Stop this at once and we'll retreat! Just don't break the Black Shackle, the Origin will damn us if you do that!! You're the Royal Black Prince, honor the tradition of your direct superior, direct God!", Arnulf kept trying to persuade Rex for stopping the energy stream.

Arnulf tries to fight the force and approached Rex desperately.

With the moonlight energy amplifying his physical prowess and also creating a translucent shield in front of him, Arnulf becomes way stronger and able to resist the force but walking forward is a different equation.

Taking one step requires his full power, it's simply impossible to approach.

But replying with nothing but an evil smirk, Rex glances at Arnulf with a ridiculing expression.

"I think you have the wrong idea about me Arnulf, you only know my name and bloodline. I never consider myself as one of you and to hell the Werewolf Origin. If the Origin came and confront me himself then I'll kill him too!!"

Declaring fiercely, Rex gazes at the Countess before putting the last ditch of his energy.

SWOOSH!!

A spark of Dark and Red moonlight energy traverses powerfully before they destroy the Black Shackle into pieces. A powerful gush of Dark Moonlight started gathering at the Countess like a vacuum, and the world started to shake strongly.

Evelyn is the only one from Rex's side that witnessed this terrifying phenomenon.

With their bodies damaged beyond measure by their opponents that are ruthless in every way possible, Adhara went unconscious from overexerting herself while Kyran can only lie on the ground.

In an instant, the Countess opens her mouth and roared like a devilish being.

A black soundwave travels through the surroundings but Evelyn got goosebumps as the roar is silent, she can't hear anything at all from that roar as if she becomes deaf or the world has been silenced. Not one of them can hear her roar.

Everyone but Rex...

Rex can hear the maniacal roar that makes him fall onto his knees once more.

It's like the roar ignited something within him and the Dual King Mark on his forehead started to burn vigorously, Rex felt like his mind is being torched from the inside and the skin on his forehead started to burn.

Under the others' gazes, the black side of the King Mark engulfed the red part.

Soon Rex's King Mark completely turns black with its edges glowing with white light that amplifies the black color of the King Mark, it's a perfected King Mark belonging to the Dark Full Moon. But Arnulf finds the King Mark strange, it has a purplish hue to it.

ROARR!!

A deafening roar escapes Rex's mouth as he spread his arms wide apart.

The Countess of the Dark Luniric shifted her gaze from glaring at Arnulf back to Rex, she then turns into energy before she completely went inside of the King Mark on Rex's forehead. It puts Rex in agony as he stumbles around while holding his head.

It's a painful process but his eyes can vaguely read the notification from the system.

<Break the Black Shackle imprisoning the Countess of the Dark Luniric: 1/1>

<Congratulation on finishing the Banished Dark Moon Quest!>

<Countess of the Dark Luniric has begun engraving the King Mark of the Banished Dark Moon!>

With the notifications from the system, Rex composed himself but the pain overreached the limit of his pain tolerance as the energy within him starting to go on a rampage. Everything gathers into a mark on his forehead that is slowly being perfected and glowing.

Upon the last dip of energy flow into his forehead, "RAARGHHH!!!!"

KABOOM!

Evelyn already saw this explosion coming as she managed to reach for Adhara and Kyran in time and covers them with her body, it was a devastating explosion that even overcome the explosion of a nuke but this is an explosion of pure Dark Moonlight energy.

It completely covered dozens of miles in the rampaging black purplish energy.

Forests that are fought by the explosion got wiped off of the face of the earth, Mountains got leveled, and rivers went dry. It all happened while the ground is shaking, everything that the Dark Moonlight energy touches turn into nothing.

But when the energy touches Evelyn, it shifted in direction and passes by her.

She noticed the energy doesn't touch her and the others much less hurt them, and this made her look back with a smile. It seems Rex is still in control despite his energy being berserk like this.

SWOOSH!

When the explosion ended, Evelyn saw the plain turns oblivious of anything.

It turns completely into dead ground with nothing except scorched ground. Arnulf and the others are heavily hurt from the explosion, Ruston and Ian were the ones influenced the most as half of their bodies were torched.

Half of their bodies were nothing but burnt flesh with poking bones.

Despite their regenerating ability, they are unable to heal half of their bodies. The wounds are permanent as the power of the Dark Moonlight energy is too powerful to resist, Arnulf stands back up before gazing at the center of the place.

But out of nowhere he saw the entire sky covered by black clouds.

A crack in the middle of the black clouds shows the Dark Full Moon glowing brightly, it's not even the time for the Dark Full Moon yet but the scenery shows otherwise. It's a phenomenon that is well-known in the Werewolf race.

"Night of King Parturition...", Arnulf mutters with a hint of confusion and helplessness.

Even Ruston that is closer to Arnulf heard his mutter and instantly recognize the bearing of this night, every Werewolf knows Night of King Parturition, "It's the night birthing a new Werewolf accepted by the Full Moon..."

"It's the night where a King is being birthed"

While he realizing the night, Ruston finds black spots falling from the sky.

It looks like snowflakes but soon realized that it was black purplish ash, they were then attracted to a heavy growl coming from the middle of the destroyed place. There's a Werewolf there that has many of these black purplish black ashes surrounding him.

But the true eye-catching trait was the mark on his forehead, it was a King Mark.

Rex forces his body to stand up before his purple eyes gaze at the remaining survivors, black purplish energy swirls around his body like a snake with the Dark Moonlight descending down from the sky directly lighting his entire body like the light from heaven.

Looking down at the black purplish mark around his body, Rex smirks deviously.

<The user has been accepted by the Countess of the Dark Luniric and obtained the Banished King Mark!>

<Congratulation on achieving the huge leap toward the path to Invincibility!>
