Flash Back End,
That day, the Dragon Emperor was shaken to its very core. Never in its long life had it met someone so brazen, so unapologetically arrogant. Rex had looked down on his father with such certainty as if his full power were unnecessary. That kind of confidence… no, that kind of dominance—it wasn't something you could fake.
What was truly terrifying wasn't just Rex's arrogance—it was the fact that his battle with the Primordial Dragon had been dead even. Despite all odds, despite everything stacked against him, Rex stood toe-to-toe with a being older than kingdoms, and it hadn't been one-sided. That realization alone sent a chill down the dragon's spine.
But what haunted it most was Rex's job class—[Eye of Infinity]. It held three terrifying abilities, each more broken than the last. And how did the dragon know this? Because Rex, in all his overwhelming confidence, had talked about.
"Let me be generous and school you as i kick your ass, It's only right you comperhend the vast gap between us." he had said with a smirk.
The first ability was [Perfect MP Control]—a passive skill that didn't need to be learned. It came with Rex's eyes by default and granted him such precise control over his mana that, effectively, he had infinite MP.
The second ability was [Never Ending Energy]—a terrifying power that gave Rex complete mastery over every form of energy. Unlike [Perfect MP Control], which applied only to magic power, this skill extended far beyond. Ki, stamina, mental energy. Rex could harness and regulate them all with flawless precision. It was as if his body and mind operated on an endless fuel supply..
And then there was the third ability… the one that truly chilled the Dragon Lord to its core: [Ever Lasting].
This skill was deceptively simple in concept, yet horrifying in practice. Any buff-type skill or spell cast upon Rex, no matter how short its duration, would remain active for as long as he continued to fight. A spell meant to last two seconds? It would now stretch across the entire battle. There was no extra cost, and no effort needed to maintain it. Just the will to fight.
It was absurd and overpowere. But what made it worse… was the fact that Rex's children had inherited [Eye of Infinity]. That alone made them a threat of unimaginable scale.
"You're holding Rex!" Momon shouted, stepping in front of the others without hesitation. His sword was already drawn. The threat before them wasn't something the others could handle
"Holding? Haha! I ate him!" The Dragon's booming laughter echoed directly into their minds, rattling their skulls and leaving each of them momentarily dizzy. It wasn't just noise—it was power, overwhelming and suffocating.
"But now, I shall eat you all to speed up my growth!" the Dragon Emperor bellowed, its massive jaws opening wide as if to swallow the entire group whole.
But then—suddenly—it stopped.
The air trembled as the beast froze mid-action. A faint groan of pain threatened to escape its throat, but no sound came. It couldn't move. Not even blink. Its colossal body, so powerful and fearsome, was locked in place.
"Man, I was hoping to have a few more months to study the damn thing… but I sensed someone I used to know."
The calm voice echoed from deep within the Dragon Emperor's gaping maw. Michael, Momon, Mikoto, Mia, and Nabe all stiffened in unison. Their sharp eyes tried to make out the figure stepping out from within, but the distance—and the sheer scale of the dragon—made it difficult.
Still, they didn't need a clear view to know who it was. Their instincts screamed it. It was Rex.
"Impossible! I ate you!" the Dragon Emperor roared in their minds, its disbelief shaking the ground beneath their feet.
"I allowed you to," Rex said lazily. "I figured you wanted to steal your father's powers, and I was curious to watch the process unfold."
The Dragon Emperor's massive body trembled at those words. For a long, tense second, it didn't move. Then, in a flash, its colossal form began to shrink, condensing rapidly until it stood at roughly a hundred meters tall—its ideal size. A mistake its father had made during their battle was relying too much on raw mass, which only served to slow him down. But not this time. With its muscles compressed and body leaner, the Dragon Emperor's speed surged to terrifying levels.
"Die!" it roared, lunging forward with a claw swipe that split the air.
Rex casually sidestepped the blow. The Dragon Emperor didn't stop—its claws tore through the sky again and again, moving so fast they created thunderous sonic booms with each swing. Yet Rex, without any hint of urgency or strain, dodged every single strike. His movements were so smooth and effortless, it was terrifying.
Enraged and frightened, the Dragon Emperor shot backward, its wings cracking the air as it created distance. Without wasting a moment, it activated its primordial magic, its only chance. It could seal away just one of Rex's job classes, so it targeted the same one its father had locked away in their legendary battle. As the binding took effect, the Dragon Emperor felt a surge of confidence.
Sensing the job class fall dormant within Rex, the Dragon Emperor surged forward, its entire body tense with power. Unlike its father, it had surpassed him—it was now stronger than its predecessor had ever been during his fight with Rex.
"I've sealed your job class!" it bellowed, its voice filled with triumph. "Without that, and against my overwhelming strength… you're dead!" The Dragon Emperor rocketed toward Rex, determined to finish the fight before the tide could turn.
The Dragon Emperor moved, its massive claw striking out with terrifying speed. In a blink, it reached Rex and struck him with a blow that shook the heavens. The impact sent Rex hurtling through the sky like a blazing comet, the sheer velocity of his flight tearing through the sound barrier with effortless ease.
But the Dragon Emperor didn't pause—not even for a breath. It shot forward, relentless, a streak of destruction chasing after its prey. Each of its follow-up strikes was laced with primordial magic, magic potent enough to bend, twist, and rewrite reality itself.
Rex was knocked through the air, his form flickering from the friction and pressure of his own momentum. Every time he tried to regain control, the Dragon Emperor was already there, appearing in his path with another crushing strike. Blow after blow rained down—millions in the span of ten brutal minutes.
Then, with one final roar, the Dragon Emperor slammed Rex toward the ground. The moment his body hit, the earth erupted with a thunderous explosion that lit up the horizon, sending shockwaves across the land.
"You should be dead, no one could have survived that!" the Dragon Emperor said, its eyes fixed on the towering mushroom cloud rising from the crater where Rex had crashed. The ground still trembled, scorched and cracked from the sheer force of the impact.
Momon, Michael, and the others stared from afar, the shock evident in their eyes. After everything—the speed, the relentless barrage, the overwhelming force of each strike—there was no way anyone could survive. Each blow from the Dragon Emperor had been beyond even a Super Tier spell. Surely, Rex was gone.
"And who decided that?" The voice cut through the air like a blade. It was relaxed, as if the person was having a peaceful walk in the park
The dust began to swirl and fade, revealing a figure standing tall at the center of the crater. He stood, butt naked without a hint of shame. After taking so many attacks, his body didn't even hold a single scratch., his posture utterly relaxed, as if the last few minutes of devastation had been little more than a breeze.
"I-Impossible! How are you still alive?" the Dragon Emperor stammered, instinctively stepping back in disbelief. The sheer number of devastating blows Rex had taken—any one of which could have killed even the former Dragon Emperor—should have turned him to ash.
"Impossible, you say?" Rex echoed, his voice calm yet brimming with mockery. He took a step forward.
The ground beneath his feet began to wither and crumble, decaying into dust with each step. The disintegration spread outward, as if the world itself was recoiling. "Who decided that?"
This wasn't the doing of [Apex Singularity]. No—this was the power of [Vector Monarch].
"You said you sealed away my job class?" Rex asked, his tone casual, almost amused. "Who decided that?"
The ruined ground beneath him trembled before reversing course—ash and dust gathering, flowing like liquid toward his outstretched hand. In moments, it reshaped itself into a gleaming golden sword, humming with unmatched power. This was no ordinary weapon. It was the product of [Vector Alter], a spell that let Rex take one vector and turn it to become something else entirely.
The Dragon Emperor froze, its massive frame rigid with disbelief.
"H-How?" it whispered, stepping back as if distance might protect it from the impossible sight before it.
"How?" Rex echoed, his voice low but absolute. "Because I'm the Apex of life. I decide what affects me—and what doesn't. Across the 9 Realms and beyond… I, Rex Tempus, alone stand as the Honored One."
He raised the golden sword, its edge gleaming with condensed power, and pointed it directly at the Dragon Emperor.
"This next skill… I once hoped to use it against your father, but I couldn't… not without a sword." Energy began to hum violently through the blade as the very air around them twisted.
"It's a more powerful version of [World Break]. It's called [World Ender]—the skill with the highest known attack power."
As he lifted the sword overhead, illusions of the 9 Realms spiraled into existence behind him, each one orbiting his form like divine echoes. The ground quaked, the sky darkened, and for a moment, even reality itself seemed to brace for what was about to be unleashed.
Not wasting a single breath, the Dragon Emperor began layering buffs and activating every defensive skill it could muster. It knew there was no point in running—this attack would reach him no matter how far he fled. This wasn't a simple strike; it was a space-time-ending, durability-ignoring, all-encompassing assault. The only true countermeasure was to prevent the skill from ever being activated… but fear had taken root too deeply. At this moment, it didn't have the resolve.
"Haha… you actually believed a lizard like yourself was worthy?" Rex laughed, his voice dripping with scorn. "Run along and finish your fusion. You still have some use to me, so I'll let you live, for now."
He turned away with a casual smile, unconcerned. Of course, he had no intention of letting the Dragon Emperor escape forever. He still needed to observe how the creature would evolve. Once the process was complete… then, and only then, would Rex come to collect what was his.
"Y-you show me mercy?" The Dragon Emperor asked, visibly shaken, uncertain how to process such words. It had prepared for rage, for death—but not this.
"No," Rex replied coldly. "I show you pity. Gods show mercy… don't you dare look down on me."
The words cut deeper than any blade. The Dragon Emperor's body trembled, not from fear, but fury. Rex wasn't just insulting him—he was dismissing him, belittling him as something beneath mercy. To Rex, he was a creature too pathetic to even warrant hatred. He wasn't spared out of grace, but out of disregard.
And that, more than anything, was unbearable.
With hatred burning deep in its eyes, the Dragon Emperor made its move… and fled. What, did you think it was going to attack Rex? Please—he was power-hungry, not death-hungry.
Rex didn't bother chasing him. Instead, he turned his attention to the odd group of people nearby—those who seemed to be cosplaying as him. One of them was clearly Narberal Gamma, though the man dressed head-to-toe in black caught his attention. He looked exactly like Rex had back in the game.
Rex narrowed his eyes slightly, puzzled but amused. Judging by Narberal Gamma's presence, it likely had something to do with Ainz.
Teleporting over to them, Rex stood silently, taking a long look at all five individuals. But he never got the chance to study them all as he was attacked.
Without hesitation, Michael charged at him, eyes ablaze with hatred and raw killing intent. But before he could get close, Rex's hand moved in a flash, striking him with a sharp, echoing slap across the face. The blow dropped Michael to the ground instantly.
"Rude," Rex said calmly, his voice tinged with annoyance. "Did your mother never teach you how to behave, boy? Charging in like that… and after all the trouble you went through to make yourself look like me?"
Rex exhaled softly, his mind flashing back to similar moments from his time in Japan. The drama, the misplaced anger—it all felt strangely familiar.
"Looking like you is the worst thing to have ever happened to me!" Michael roared, his voice trembling with rage.
Rex didn't flinch. Instead, he tilted his head slightly, watching the younger man with an almost bored expression.
"Then why go out of your way to make yourself look like me?" Rex asked flatly. "You're a grown-ass man, so what's this little act you're playing at?"
He shook his head, sighing like someone tired of being dragged into someone else's drama.
"You know what? This isn't my business. Whatever issues you've got, that's on you. Do whatever you want—just keep me the hell out of it."
