The Invincible Full-Moon System

As his palm made contact, a surge of energy coursed through his veins, the Drain Touch skill activating with a potent force. Instantly, Edward's life essence began to flow into Rex's hand—a torrent of vitality that filled him with newfound vigor.

Swoosh!

Five streams of life essence formed, converging into one before being absorbed by Rex.

Instead of merging with Rex, the life essence gained disappeared as soon as it entered.

As opposed to healing his wounds, the life essence went straight to his cursed source which was gaining size rapidly. Due to the corruption—Edward's life essence had become robust, it filled Rex's cursed source expressively.

On the other hand, Edward's strength waned with each passing moment.

His body grew weaker and weaker as the life force was drained from his very being.

It could be seen vividly through his face that was gradually becoming drained and frail.

Given the process took longer than usual due to his robust life essence—the pain should also be equally more harrowing—considering that most died instantly to the Drain Touch skill. But even then, Edward didn't react and persevered in silence.

His determination was unwavering, and that made it harder for Rex to continue with this.

But he knew that it was a grim necessity, and he had to go through with it.

Swoosh!!

As the amount of life essence obtained reached the breaking point, Rex could feel his cursed source was stagnant in size beginning to show signs of cracking. He let out a heavy grunt as he pulled more life essence out.

Observing through his inner eyes, he finally saw a crack on the cursed source's surface.

Even though it was tiny, the effect of its appearance was devastating.

"Raarrggrghh!"

Boom!

Unleashing a thunderous roar, Rex's body exploded with a heavy pressure of cursed energy.

Standing on the side, protecting herself from the torrential of energy, the Witch squinted her eyes and saw through Rex's corporeal form, into his cursed source. Albeit the cursed energy made it blurry to see, she could tell that a symbol was forming.

It was being carved by the cursed energy rampaging around Rex's cursed source.

A symbol that took the shape of infinity.

'Eternal Curse... I thought it was the Hatred Curse, but turned out he has something stronger'

Just when the symbol was fully carved on Rex's cursed source—another explosion of energy erupted, marking his attainment of the ninth epiphany. His cursed presence was now heavier—it was at least five times stronger, a force even the Witch could no longer overlook.

Rex, as he felt his breakthrough, instantly retraced back his arm and leaped into the sky.

He wasted no time, instantly heading to the Symposium of Upper Divinities.

It was time to end this battle once and for all.

Crash!!

Navigating through the sophisticated rock formations that were inactive proved easy for Rex as he entered the Symposium of Upper Divinities, descended from the sky, and landed in the spacious, open sacred room.

He landed at the center, encircled by ancient stonehenge and statues of legendary figures.

Dauntingly, Rex rose to his feet and gazed ahead at the Executor.

Standing near the round table was the Executor, bathed in a radiant golden glow that starkly contrasted with his deep purple chaos aura. Gripped tightly in his hands was the infamous—supreme weapon he had been dreaming of, salivating to wield its power.

As pompous as its reputation, the supreme weapon is a sacred sight to behold.

Forged and wielded by the Supreme One himself, the supreme ruler of the ancient world, it is a colossal two-handed longsword that emanates a divine and sacred energy. A blade crafted from the purest essence of gold—gleams with an ethereal brilliance, that cascades the world in its radiant glow.

Its edge, honed to perfection, possesses an otherworldly sharpness.

One that was said to be able to kill even Gods.

Adorning its length, a royal black fuller flows, like a river of darkness—a striking juxtaposition to the divine luminescence that emanates from its core. At the crossguard, the golden wings arch downward in a protective embrace—signifying celestial authority—to be able to rule the entire world upon its bearer.

Nestled within the hilt, a resplendent gem pulsates with an ancient power.

It was the Supremacy of One.

Managed to reach the Symposium and laid his hands on the supreme weapon—the Executor engraved the Supremacy of One gem into the weapon—completing it and unleashing its raw power with a manic smile on his face.

"You came at the right time, Royal Black Prince!" the Executor declared, laughing maniacally.

He was excited as he held the supreme weapon with both hands tightly.

Even though the Executor was extremely strong, he was having trouble against the torrent of energy that the supreme weapon was emitting. It was obvious that the supreme weapon was in a realm of its own if even the Executor struggled to wield it with his power.

Additionally, the energy from the supreme weapon was strengthening the Executor.

One could see that all the negative effects he endured were negated.

The Witch's ploy of corrupting the link with her cursed energy was even purified completely.

"Meet the Golden Slayer, also known as the God Slayer! It's the supreme weapon that allows me to sit on the throne of the world, and also the weapon that would slay you, forcing you to pay for your filthy arrogance for even thinking of being able to defeat me!" He continued.

Shingg!

As the torrential energy calmed down, the Executor pointed the Golden Slayer's tip at Rex.

Sparks of gold essence splashed throughout the place as he did this.

Looking at Rex—who hung his head low—concealing his expression, the Executor's laughter grew louder—as he was aroused at the thought of mutilating Rex limb by limb. He yearns for the prospect of inflicting torment and committing other atrocities that flash across his brutal mind.

But as the Executor was laughing, a sudden pulse yanked the Golden Slayer downwards.

Clang!

Its tip pivoted and crashed to the ground as if there was a magnet pulling it.

Upon seeing this, an evident frown crept across the Executor's face as he didn't understand what had happened. Grunting—he tried lifting the Golden Slayer only to find that it was way harder to do so as if its weight had multiplied tenfold.

Even by putting all his might into it, the Executor could barely wield it properly.

His arms were trembling to keep the Gold Slayer pointing forward.

"Say... If everything has gone exactly as I planned, what do you think would happen next?"

The Executor glared at Rex with gritted teeth, "Impossible!"

On one side—the Executor strongly believes that regardless of how powerful and resourceful Rex is, he shouldn't be able to alter anything about the Golden Slayer. But on the other side— he couldn't help but feel a cold tingle on his spine.

If that was true, then how come he couldn't lift the Golden Slayer properly?

He already merged it with the Supremacy of One, so there shouldn't be any trouble with it.

Exhaling heavily, Rex slowly raised his gaze to meet with the Executor's as he gradually make a transformation back into his Werewolf form. Judging from the pace of the transformation, it was obvious that Rex was exhausted.

But nevertheless, he still had enough stamina to transform one last time for the last clash.

Gradually, his body was gaining mass, and his teeth turned into fangs.

"You couldn't possibly plan this! The Golden Slayer is incorruptible!" the Executor roared.

Upon hearing this, a sinister smile gradually spread across Rex's face as he finally savored a bleak aura beginning to seep out of the Executor's body. Visibly, the Executor's strong cover was slowly crumbling down, and he slowly began to feel fear.

A sight that was Rex waiting for—his grand plan was made to finally see this tasty view.

"Since you manipulated me, in fulfilling the conditions of your awakening—I thought that you were meticulous in anything you do—but I was wrong. It seems like the only thing that made you successful in manipulating me was the fact that the plan was not yours," Rex mocked—his voice was filled with disdain.

Not going to stand and receive these mockeries, the Executor charged forward.

Leaping high, he swung the Golden Slayer down.

Clang!

Boom!!

Despite the powerful impact, Rex was able to block it with the Blood Devourer easily.

A sight that caught the Executor in a complete shock.

Considering that the Golden Slayer was way stronger than the Blood Devourer, this shouldn't be happening. No matter what—it is impossible for the Blood Devourer to be on equal footing with the Golden Slayer.

But reality proved otherwise as the Blood Devourer easily parried the Golden Slayer.

"If I really want you dead—why would I wait for you to come here when I could easily do that through other means? Gistella is within your castle, and there are a myriad of ways to get rid of you" Rex explained, his expression icy cold.

Putting more strength into his arms, he parried and threw the Executor backward.

Brandishing the Blood Devourer expertly, Rex eyed the Executor.

"Poisoning and killing you when you're vulnerable, or inciting chaos within human territory to isolate you from gathering an army and turning them against you—these are just a couple of more effective methods to bring about your downfall from the top of my head" He continued.

Since Gistella made it through the castle, these are plausible plans that could work.

Nevertheless, Rex opted for another plan and confronted the Executor here.

"Just like I said..." Rex smiled hauntingly, his presence riled with cursed energy that made his shadow stretch over to the Executor, inducing him with a chilling grasp. "I will repay the favor back to you by making you dance in the palm of my hand. All of this is under my manipulation—including the Golden Slayer.

The moment you laid your hands on it was your doom, you are chasing a false hope, Fifthborn"

Upon hearing this, the Executor's body trembled as he clenched the Golden Slayer.

His heart began to quicken, and the palms of his hands began to sweat.

"And because of that, you have no chance of winning from the start..." Rex added devilishly.

Deg!!

"Even with the gap of strength between us, you dare to try that?" the Executor asked.

However, in return, Rex only smirked at him.

"Madman... You're a madman..." the Executor mused hauntingly, he couldn't believe that Rex was brave enough to attempt to do this instead of going with the safer plan. But in a frenzy, the Executor roared and charged once again.

He swung the Golden Slayer desperately, sending a flurry of vicious but desperate attacks.

But even then, Rex easily parried them with relative ease.

It was so easy that he didn't even need to move from his spot, only his right arm was moving.

Such a sight had an impeccable impact on the Executor's psyche.

He had never been treated like this, and not once had he foresaw this to happen to him.

"How...?"

Clang!

"How?"

Clang!

"How?!"

Slash!

"HOW IS THIS POSSIBLE?!!"

As he struck Rex repeatedly, the Executor kept on repeating the same words desperately.

Despite making sure of the authenticity of the Supremacy of One and also the Golden Slayer, he couldn't understand how Rex managed to nullify its power with an Origin-grade weapon— belonging to a mere Vampire race.

Channeling the power of the Golden Slayer, the Executor leaped skywards.

Even though reality proved that his attacks weren't effective, he didn't want to believe that to be a fact, as he gathered everything he had inside of him into a single blow. He stretches the Golden Slayer over his head, bringing about divine power into his strike.

Responding to the Golden Slayer's power, the ground trembled viciously.

Fixing his eyes, the Executor let out a thunderous battle cry.

Pulling nothing back, he did a cataclysmic vertical overhead slash to end Rex for good.

Crash!

KABOOM!!

A potent impact ruptured the air, creating a vortex of destruction before blasting a torrent of wind across the surrounding area. Gasping for breath, the Executor lifted his gaze to see the Golden Slayer before his chest heaved as he drew in a quick sharp breath.

"This is the end Fifthborn, accept it. You're at death's door..."
