The Invincible Full-Moon System

It was not a loud voice, it was subtle, but it rings louder than the loudest explosion.

Nobody has expected such an outcome from the awakening of the ancient human that feeds them with the facade of destroying their nemesis, the Supernatural races from the face of the planet for good and grasping back the era of humanity.

But as it turns out, the savior that they expected also hated their existence for sullying humanity.

An individual that brought hope has turned for the worst.

People watching this sight can hear a literal dramatical violin ringing inside their ears, the sight of a literal God that they heavily respected as the bulwark of humanity prostrating under a figure that they thought would be an ally has a devastating effect.

For a brief moment, the entire place was drowned in quietness.

Every fiber of their beings goes on pause with their eyes fixed on the horrific scene that lies in front of them, their mind stutters to catch up and girder their souls to comprehend what they were seeing right now.

"Sir Orson... L-Lady Brigitta..." Jasira mutters with a cold breath.

With her mind struck powerfully by the realization of the death of her mentor, she was not ready for this scene. It's like consecutive blows to the head that shakes her brain and left her disarrayed, rattled, and confused.

Jasira has received enough surprises today, and her heart can't handle any more surprises.

Out of everyone that is survived and was present to see this rare scene, Brigitta is the one that truly knows the effect of what she was doing right now. A ninth-rank realm Awakened prostrating is a huge blow to humanity's morale.

As one of the leaders of humanity, she should've been the most unyielding person who existed.

It was her duty to keep being strong and resolute for humanity.

But in the face of the hidden horrific that she and Orson have awakened, in the face of absolute power that surpassed her logic of the entire world, there's nothing she could do except submit and blame themselves to awakened this monster.

Someone that doesn't care about them and views them as lesser beings.

"With such sincerity in your words, I can only humbly forgive your careless behavior that does not know your own limitation. After all, I am your Savior and I am a forgiving person" the Executor replied, the suppressing air around him turned into an air of reverence.

Definitely a fake one that is put on to only shows his dominance to the entire world.

After handling the matters with Brigitta, the Executor looks over his shoulders and finds Rex still kneeling on his spot. No sign of movement can be seen, he just stayed there and seems to be mumbling something.

"Oh... you're still here?" the Executor mumbles and approaches once again.

Upon stepping closer he can hear Rex's mumbles that are getting louder inside his ears, but it was still inaudible and makes him frown. "Leave this place before I changed my mind, Royal Black Prince. I have numerous powers and many superior traits, but patience has never been one of them"

The Executor stands in front of the kneeling Rex, the same as before.

Stretching out his hand with the intention to grab Rex's hair, a hint of kingly energy suddenly sparks around Rex's remaining arm. A subtle kingly energy that rapidly increases in mass and becomes more violent in the blink of an eye.

'What's this...? My senses are reacting to this' the Executor thought, troubled by the kingly energy.

"Don't explode... Don't explode... Don't explode..."

Rex keeps muttering the same words over and over again, almost as if he chanting a powerful spell.

Utilizing his devastatingly fast reflex that matches if not faster than Rex's inhuman reflex, the Executor harnesses his Chaos element and summoned it into his arms. It was almost like an instinctive reflex, beckoning him to take the kingly energy seriously.

Soon Rex raises his gaze with his savage expression and his King Mark glowing brightly.

"Don't humor yourself too much Executor, it's not my first time meeting an overwhelmingly powerful opponent. And like the rest of them, eventually, you will succumb to my claws" Rex said harshly with a tone full of confidence, it was a confidence that he gained from everything that he had gone through with the system. On top of that, from the system's perspective, the Executor is nothing but an obstacle necessary to reach absolute invincibility.

In simpler terms, the Executor is just the next milestone for him in his path to power.

Clenching his remaining hand into a fist, the kingly energy inside his arm glowed and condensed strongly, solely to the fist. Red linings, almost like cracks on his skin appeared and also gushed insurmountable kingly energy, way denser than before.

Responding to this, the Executor wants to jump away but he was stopped, 'Hmm...? I can't move'

"I will not let myself be humiliated and spared by the likes of you, if I want to escape then I'll do it my way. Try overpowering this, Executor. I'd like to see just how strong you truly are..." Rex mutters, and the violent kingly energy reacted to his chant.

Unable to move his body, the Executor looks at the punch heading toward his face.

As his senses were reacting to this attack, he decided to cross his arms in front of him to block.

Bam!

But under the Executor's fixed gaze, the punch stopped a couple of inches away from his crossed arms with a loud blasting sound. Following that punch were some kind of ancient writings written in crimson color spread like a star in the space in front of the Executor, slowly crawling into existence.

Ancient engravings that slapped a surprised look on the Executor's face.

"Moon Ability, Brutal Impulse..."

KABOOM!

Despite the immense reaction possessed by the Executor that helped him block the attack while simultaneously activating his Chaos element, a gush of violent spiraling energy blasted him with immense power that pushes him back.

It looks like a red beam that is surrounded by sound waves spiraling around it.

Albeit the Executor's attempt his strong legs were slowly being pushed back by this attack, and the blast that went past his body destroyed everything on his back in a straight line. Like a laser that can evaporate and distinguish anything that it touches.

The shockwave created a crippling sound that is very sharp even for the Awakened.

"Argghkk!"

Jasira and Ryze alongside the other few surviving Awakened have their eardrums instantly shattered by the sudden crippling sound invading their ears, it was brief but very loud that the air itself trembles due to the sound produced.

Under such an intense amount of power, the Executor's Chaos element also becomes violent.

Fundamental arcane elements gathered onto his crossed arms before purple blazing energy was produced, the Chaos element then travels throughout the Executor's body and armor while simultaneously making his eyes glow fierce purple.

"Dark Chaos Magic, Energy Annulment"

With the intention of swinging his arms, the Executor fought the resistance and prevailed.

Crash!

A glass-shattering sound can be heard as the Executor managed to disperse the violent kingly energy that was threatening to tear him apart, dust exploded into the surroundings, and his purple eyes peer from the midst of the dust and smoke.

Inexplicable emotion riled up within him, and he jumped out of the smoke and landed outside.

Looking at the spot where Rex should be has gone empty, his face darkened realizing that Rex has already escaped in that momentary gap of him dealing with the sudden outburst of kingly energy. With this realization, he looked down at the spiraling vambraces on his arms.

The Executor paused for a moment before a mysterious glint appeared in his eyes.

"A Direct Moon Ability, the Royal Black Prince is more capable than I originally thought" he mutters to himself while looking at his vambraces that have their edges cracked, the power behind Rex's attack managed to actually damage him and draws a drizzle of blood!

Something he truly was not expecting, but he was not that surprised.

As he has already said that he would spare the Royal Black Prince this one as thanks for breaking the seal, he intends to honor his own words. It was his own words, if he doesn't honor it then he would be putting dirt on his own name.

"Next time, there will be no mercy" the Executor mutters silently.

Just when he was about to turn around and handled the affairs of humanity, his steps stopped and his eyes went completely round. Even the Brutal Impulse was not able to incite this kind of reaction, but the Executor seems to be very surprised right now.

Nothing astonishing particularly happened and yet the Executor is surprised.

Brigitta doesn't know what makes the Executor this surprised, but something definitely happened to make him expose this kind of reaction. "T-This... This is not possible, I've seen this before but how can this be possible?!"

Looking back to where Rex has gone off to, the Executor gritted his teeth.

While he was walking away a blue-chrome box appeared in his vision, there are written characters on it and he was completely caught off-guard. More than the sudden appearance, he was surprised because he has seen this holographic box that appeared in his vision.

'Is that Werewolf has a connection with the First Human Emperor?!' he shouted inside his head.

Meanwhile, Rex managed to escape the place on his own carved path.

In the extreme heat of the moment he managed to pull off activating the Brutal Impulse Moon Ability without exploding his remaining arm, he would've lost both arms if he made the slightest bit of mistake there.

Rex was even surprised by himself, but that might be his instinct kicking in.

Not wanting to be humiliated much less spared by his own enemy that has used him to awaken, the survival instinct and also pride got involved and allows him to actually use the Brutal Impulse Moon Ability despite the impossibility of using it consciously.

But looking at his current remaining arm, the drawback is devastating.

With only one use of the Brutal Impulse Moon Ability, his arm instantly went numb and was not able to be moved at all. It's almost as if his arm becomes crippled, or exhausted to the point of being unable to do anything but sway along the movement of his body.

Although he suffered the repercussions of using that, he learned something from that fight.

'Brutal Impulse... It seems I can use it to literally amplify anything that is a part of my body' Rex thought with clarity in his eyes, he realized it when he tries to activate it earlier. For a moment, he can feel that the kingly energy can be guided to any part of his body.

It needs to follow the specific energy circulation, but the end can be assigned anywhere.

Just then he channeled the end into his arm and use it to amplify his punch, maybe if he actually mastered it then he can run tests on the varieties he can create using the Brutal Impulse skill. 'But I need to get stronger first, the Executor wouldn't just let me get stronger'

Rex nodded his head, his determination can be seen on his face.

Knowing that the Executor is his stepping stone to a new height of power, he was thrilled, he now knows for a fact that he can still get way stronger. Only by reaching absolute invincibility will he be able to do whatever he wants and protect those who he cares about.

After reaching a distance away, he stopped by a tree before he started vomiting blood.

<Warning!>

<The user's condition is critical, it is advised to rest and bathe under the moonlight!>

"I can't, I need to get back first before resting" Rex mutters, it's not safe to be outside anymore with the presence of the Executor. Moreover, he doesn't know how long until the effect from the Mist of the Starfallen that allows him to be untraceable by the Executor fades.

As he was about to continue his journey, a couple of notifications appeared once again.

​ <Sudden Quest has only been partially completed!>

<Thre rewards for the Sudden Quest have been shared with the rival of absolute invincibility!>

<Congratulation the user has obtained 1 trillion exp and 3 million gold!>

<Level up!>

<Level up!>

<Level up!>

<Level up!>

Upon reading these notifications, Rex paused and his body stiffens, 'What...? Shared...?'
