The Invincible Full-Moon System

Unseeable by the eyes of the onlookers, numerous haunting vibrations crawl through the stuffy air and creep into the eardrums, turning into evocative whistling sounds which sounded like the whispers of the souls of the fallen.

Nothing can escape the grasp of this darkness, not even the world itself.

Anything that gets touched by this inexplicable darkness turns into the color of bleakness and death, ivory-grey. The source of power that weakens the beauty of colors a living being can see into nothing but a fragile world of ivory-grey.

Entertainment of the world was robbed, and the five senses were dulled in this turned bleak world.

It doesn't matter how long he has gone through without feeling this sensation. Just the tip of the taste of this sensation that seeped into his bones, he easily recognized it. The feeling of helplessness that dawned on Rex can't be mistaken by him even if it comes in myriads of ways.

Rex who is watching the entire place changed into something he couldn't recognize froze.

Nothing seems to be the way it was and it was all the doings of a beating that watches over him from above, a being that instills fear in the hearts of Supernatural. Flying like a literal God of Death that has come to collect the souls fated to die today.

'So this is the Executor...'

One by one, countless veins inside his eyes exploded just from seeing the Executor above him.

Although he has seen the upper echelon inside the absolute realm of power, he has never felt this much oppressive force just from looking at a creature. It feels like his entire body is being drowned in the bottom of the ocean, and the current threatens to crush his entire body into nothingness.

The Executor's presence is too strong that even Orson and Brigitta can't take a look at him.

Standing in the sky with his eyes looking down on others like a higher being, the Executor's body is slender and long. Rex can tell that the Executor is way taller than him, even with the distance between them. A bearing of mystery and ancient covers his entire body alongside the flaming black energy that contains numerous energies mixed together.

From a knit of his eyes, Rex can tell that the mix of energies is elemental arcane mana.

In this era, the Awakened that is considered a Dual Elementalist is a genius amongst genius. An occurrence that happened only once in countless thousands. Rex only knows a couple considered to be Dual Elementalist, and he's standing at the top of the world.

Just from this alone shows that Dual Elementalist Awakened is a rare sight for anyone.

But if his eyes are not deceiving him, the flaming thick black energy consists of not just two elemental arcane mana. 'Four, he has four elemental arcane mana fused together and create a breed of an element. Chaos element...' Rex sucked in a cold breath.

Rex's eyes glowed to actually see the mana around the Executor using his Awakened eyes.

As soon as he did that his back started to be drenched in his cold sweat, and he saw the massive difference between their elemental prowess. The Executor's power envelop Rex's entire vision, while his Dual Elements were nothing but a spec of light inside this darkness.

'Is this really the power of one entity...?' Rex thought in disbelief.

Even though it's horrifyingly unbelievable for one entity to possess so much power, Rex was forced to swallow this as that very entity is standing in front of him now. Clad in a sleeveless robe and heavy combat plate armor underneath that matches its ashen skin, the Executor's sharp red eyes are now staring straight at Rex.

"We meet again, Royal Black Prince..." the Executor opens his mouth and said.

But out of the things that Rex thought the Executor would say, he didn't expect the Executor to say this, "Meet? I've never met you before. If I'd met you somewhere, I would've remembered it without a doubt" Rex replied with a frown.

Although he said that, for some reason, the voice sounded similar.

It's like they really must have met before, but he doesn't remember where he heard the voice from.

Upon seeing the confused expression on Rex's face, the corner of the Executor's mouth quirks into a devilish smirk. A haunting one that alerted Rex's danger sense, "Maybe doing this would refresh your memory" he said before he bowed slightly and reaches one of his hands out, "One Light Elemental Orb for the Prince of Werewolf, it is my pleasure..."

DEG!

Rex's heart skipped a beat when he heard that, his mind was really refreshed instantly.

"W-What...? You're the ancient spirit from the Carabidis Temple! But how, no... if you're the Executor, why would you help me back then?!" Rex exclaimed in surprise, he was absolutely caught off guard by this as in no way he would've thought the Executor is the same as the ancient spirit he met in the Carabidis Temple.

Not only that but their appearance is also vastly different, with no similarities at all.

Back then the ancient spirit in the Carabidis Temple looks to be a knight of light, clad in golden armor and even shining brightly. Compared to the Executor now which excludes heavy black energy, it's not the same at all!

Orson and Brigitta behind the Executor heard their conversation.

Although this is their plan to make Rex and the other ninth-rank realm Supernaturals faced the Executor, they didn't expect the Executor to be an acquaintance of Rex. But it doesn't matter, as long as the Executor kills Rex in the end.

Savoring the surprise on Rex's face, the Executor's smirk stretched even wider.

"The Supreme Being whose name is unfit to be expressed by the likes of you foresaw the fall of Humanity and the rise of Supernaturals that wanted to denounce Humanity's supreme standing and take over the world. So he created me ahead of time. An entity that is made through his evilness, and can triumph over the limiter that destroyed Humanity, and be awakened when the time of Supernaturals' blasphemy happened and put an end to it"

"With his highness' supreme intelligence, he created a three-layered seal"

The Executor raised three of his fingers that are more like devil claws instead of human fingers, he takes a great sense of enjoyment from seeing Rex's expression crumple more and more the more he continues his explanation.

"The first layer is broken thanks to you, Royal Black Prince..." the Executor whispers eerily.

Rex clenched his fists as he was not expecting this to be his fault too, he was just blamed by King Solomon for what he did. And now, the Executor said that the first layer of this three-layered seal is broken because of him too?

The Executor then continues his explanation, "Out of the three layers, the first layer is the most important. I need to awaken exactly at the right time when the Supernaturals are attacking humans, and that is achieved by creating the Carabidis Temple that would change location in a fixed amount of time to lure anyone that seeks power. The purpose of the temple is to search for a royal or a powerful Supernatural which will indicate the Supernaturals have broken the seal they are trapped in, and awaken me using their blood"

"And guessed who came? You..." he added with a mocking tone, delighted that he has awakened.

Upon hearing this Rex can't help but widen his eyes and his body froze, he remembered clearly that he was stabbed when he was about to take the Carabidis Temple's Gem. There was a coffin there, and as it turns out that coffin contains the Executor.

It was his blood that got splattered on the coffin and awakens the Executor.

"I-Is it really my fault...?" Rex mutters silently, it was inaudible as he was stricken in terror.

The Executor tilted his head a little with the stretched-out devilish smirk still etched on his face, "What? You don't really think that the Black Dandelions are there just for decoration, did you? Don't be fooled, those plants are there to filter whether the seeker of power is a human or not, simple as that"

DEG!

Rex's heart started to thump hard, he knows that there was something wrong with the place.

During that time in the Carabidis Temple, he was skeptical about the ancient spirit, it was radiating with golden light but its attitude sometimes didn't align with the golden bright energy it was emitting. As if there's a hidden darkness, the way it looked at Rex with disdain shows that.

But since some time has passed, he thought nothing of it.

As it turns out he should've been more worried about the Carabidis Temple, now that skeptical feeling has taken a nasty turn and awakened the Executor that came here to end all Supernaturals by the order from the First Human Emperor.

Slowly the demons from the past started to catch up to him and stab him in the back.

The Executor keeps on explaining the second layer of the three-layered seal but the sounds that entered Rex's ears have already turned muffled, his mind was occupied and his senses starting to numb. 'I-Is everything my fault...? Did everything that goes wrong in this world be my fault...?'

Negative thoughts started to occupy his mind, and devour any light that wanted to prevail.

Rex understands very clearly that no matter what, he can't prevent this from happening. The Executor played the long game and even fooled him into thinking that there was nothing wrong, he wouldn't have sniffed the wicked plan of the Executor no matter how much he tried.

It was fated to happen, the awakening of the Executor is inevitable.

Just then Rex remembered an important piece that makes his eyes widen, 'No... this is not my fault. The system is the one that sent me there by issuing a Pack Quest, I'm there because the system told me to go there'

'But why would you do that? Why not tell me that the Executor is plotting against me?!'

Since he has been utilizing the system to become stronger, he knows that the system has the capacity to issue a sudden quest to any threat that appeared even when Rex didn't know that the threat has appeared.

If the system acted normally, then the system would've issued a sudden quest for this situation.

The system would issue a sudden quest right after he finished the pack quest and stepped out of the Carabidis Temple, but the system didn't. 'Tell me why! Tell me why you didn't tell me about this?! Answer me!' Rex roared inside his head.

Although he has done that in a fit of anger, three box-shaped interfaces appeared.

<My purpose is to make the user invincible under the full moon and to become invincible means the user would be standing on top of everything and become the absolute overlord of the entire realm of existence. Able to win against any source of power in the entire realm of existence, including the Gods that await a challenger in the higher plane>

<In order to reach absolute invincibility, the user needs to be exposed to all kinds of threats>

<Failing to reach absolute invincibility is not allowed, the user would either reach absolute invincibility or die trying to reach that realm. It's advised to look at the current situation as an opportunity. With my help, there's nothing that can reach the sense of impossibility>

Upon reading through these notifications, Rex's expression turns grim.

'A selective alert huh... so you deliberately don't notify me about the Executor's presence to make me face it, I see now. If that's the case, I look forward to the time when I can defeat this monster in front of me!' Rex thought before he refocuses his attention back on the Executor with a new sense of relief.

<Yes, the system will do everything to assist the user's climb to absolute invincibility>

If the awakening of the Executor is inevitable, then he would only need to think of the present.

Rex's eyes glowed as his battle instinct came back to him, he's man enough to admit that he lost to the Executor's plotting and dances in his hand. But that doesn't mean he's going to keep on losing to the Executor.

'No matter what, I'm surviving this ordeal. I'll gain the time to get stronger to destroy this thing!'
