I FOUND A DOOR TO TENSURA AND BECAME BROKEN IN THE REAL WORLD TOO-Chapter 30: Mastering Sovereign Dominion

I turned to Veldora with a confident grin.

"Hey, Veldora. Let me try this new ability on you."

The Storm Dragon raised a curious brow, then his mouth curled into a smug grin.

"OH HO? YOU WANT TO TEST YOUR NEW SKILL AGAINST ME?" He let out a deep chuckle, clearly entertained by the idea.

"HUMAN, DO YOU HAVE A DEATH WISH? EVEN SEALED, MY PRESENCE IS BEYOND YOUR COMPREHENSION."

I held his gaze without flinching.

"I'm not scared of you." My voice was calm, firm, and unwavering.

"And besides... you're sealed. You can't fight back anyway." I smirked slightly, taunting him.

Veldora's golden eyes narrowed dangerously, but he grinned in amusement.

"HAAHAAHAA! YOU'VE GROWN BOLDER, HUMAN. FINE! LET US SEE IF YOUR SO-CALLED ENERGY DRAIN CAN EVEN SCRATCH A TRUE DRAGON!"

I stepped forward, standing just outside the perimeter of his golden seal.

Taking a deep breath, I extended my hand, focusing on my new skill.

I could feel the tendrils of power slithering outward, reaching toward Veldora's enormous magical presence.

My fingers tingled as I activated Energy Drain, feeling the skill latch onto Veldora's magicules like invisible chains.

For a moment, nothing seemed to happen.

Then, I felt it.

A small surge of magicules flowed into me—like a river of raw, untamed energy, pouring into my veins. My stamina and magic reserves spiked slightly.

"Oh... it's working." I whispered in amazement.

However, Veldora suddenly burst into laughter.

"BAHAHAHAA! IS THAT ALL YOU'VE GOT?!"

he roared mockingly.

"I BARELY FELT THAT! YOU'RE TRYING TO DRAIN A TRUE DRAGON, HUMAN! YOU'LL NEED FAR MORE POWER THAN THAT!"

I clenched my teeth and focused harder, pushing my magicule control to the absolute limit.

"Don't underestimate me." My voice was sharp, filled with resolve.

The Energy Drain intensified. The tendrils thickened, glowing faintly with crimson light as they burrowed deeper into Veldora's essence.

I felt a much larger stream of magicules flow into me, and my body practically thrummed with energy.

"Hah... hah...!" My breath came out in short bursts, but I could feel my stamina replenishing instantly as Veldora's magicules were drawn into me.

I grinned manically, feeling my power swell with each passing second.

"Now THIS... this is power."

Veldora's eyes narrowed slightly, clearly noticing the unexpected increase in the energy being stolen.

"HOOOOH? YOU'RE DRAINING MORE THAN I THOUGHT YOU COULD." He smirked approvingly, his eyes flashing with interest.

"IT SEEMS YOU'RE STARTING TO GRASP THE TRUE NATURE OF YOUR SKILL. IMPRESSIVE."

I pulled back, releasing my hold on the skill.

The cavern air crackled slightly with residual magic as I lowered my hand, feeling the afterglow of stolen power coursing through me.

I checked my status screen. My magic capacity had increased slightly from the fight, and my stamina was fully restored.

"So, I can actually grow stronger mid-battle by absorbing energy from my opponents..." I muttered under my breath.

"This could be... broken."

Veldora's lips curled into a devilish grin, clearly pleased by my rapid improvement.

"WELL DONE, HUMAN. ENERGY DRAIN IS NOT A SIMPLE ABILITY. IF YOU MASTER IT, YOU'LL BECOME A NIGHTMARE TO FIGHT." His golden eyes gleamed dangerously.

"YOU COULD STEAL AN ENEMY'S VERY LIFE FORCE IF YOU PUSH IT FAR ENOUGH."

My eyes widened slightly at the implications.

"Their life force...?"

Veldora's sinister grin widened.

"YES. WITH ENOUGH CONTROL AND INTENT, YOU CAN DRAW NOT JUST MAGICULES BUT EVEN THEIR VITAL ENERGY." He leaned closer, his voice low and menacing.

"EVEN DEMON LORDS... EVEN OTHER TRUE DRAGONS... WOULD FEAR YOU THEN."

I stared at my hands, trembling slightly with excitement.

The weight of the skill's potential settled over me like a cloak of power.

"Heh... looks like I'm going to be stronger than I thought."

I clenched my fists, my eyes flashing with determination.

"And this is only the beginning."

As I stretched my limbs and prepared to leave the cavernous chamber, Veldora's deep, rumbling voice echoed through the air.

"HUMAN... WAIT."

I turned back, raising an eyebrow curiously.

"Hmm? What is it?"

The Storm Dragon narrowed his golden eyes slightly, his gaze sharp and inquisitive.

"I JUST REALIZED... AFTER ALL THIS TIME... YOU HAVE NEVER TOLD ME YOUR NAME."

I blinked in surprise.

It was true—I had spent weeks talking to him, learning from him, and absorbing his knowledge, yet I had never actually introduced myself.

A small smirk played at the corner of my lips.

"Heh... that's true, huh?" I chuckled lightly, then stepped forward, planting my feet firmly as I faced him.

"Tenjou... Yuuya." I paused deliberately, letting the words linger.

"My name is Yuuya Tenjou."

Veldora's eyes widened slightly in recognition of my bold, confident tone.

For a brief moment, he was silent, then his deep chest rumbled with mirth.

"HAAAHAHAHAHAA! TENJOU YUUYA, HUH?" His booming laughter shook the cavern walls.

"VERY WELL, TENJOU YUUYA! I SHALL REMEMBER THAT NAME!" His voice lowered slightly, becoming more somber yet resolute.

"I CAN'T WAIT TO SEE HOW STRONG YOU WILL BECOME."

I gave him a faint smirk, my eyes gleaming with determination.

"Oh, you have no idea..." I muttered under my breath before turning around.

Without another word, I strode deeper into the labyrinthine cave, my fists clenched and my heart pounding with anticipation.

I was ready to push my limits and master my Unique Skill—to force it into evolution, no matter how long it took.

The deeper I ventured into the Storm Dragon's cave, the darker and more treacherous it became. The air was thick with the remnants of Veldora's magicules, pulsating like an unseen force, constantly mutating the creatures that dwelled here.

It wasn't long before I encountered my first challenge.

A giant lizard, its body covered in obsidian scales, slithered from the shadows, its fiery eyes locking onto me. The instant killing intent it radiated was enough to paralyze any normal human.

But I was far from normal.

I took a steady breath, activating Sovereign Dominion as my Command Aura surged outward. The air crackled with unseen energy as the beast suddenly froze, its instincts screaming that it was now beneath me.

"Not bad. Let's test Energy Drain."

I lunged forward. The lizard snapped out of its fear, roaring as it lashed its tail toward me. I dodged effortlessly, my movements sharper than before thanks to the weeks of training I had undergone.

I extended my hand, focusing my will—thin, invisible tendrils of magic surged from my palm and latched onto the lizard's body.

It struggled. It roared. But it was useless.

I felt its life essence trickling into me, my stamina replenishing, my magic pool expanding. The more it fought, the faster it weakened.

"This ability is ridiculous..." I muttered as the beast collapsed, completely drained of energy before I even delivered the final blow.

I crushed its skull under my foot, watching as its magicule-infused corpse disintegrated into the cavern's environment.

I lost track of time in this vast underground labyrinth. If not for the timekeeping ability I had developed—something similar to a digital clock embedded into my mind—I would have had no idea how long I had been down here.

I fought everything the cave threw at me.

Draconic Serpents with scales harder than steel.

Giant Spiders that spat acidic webs capable of melting stone.

Shadow Hounds, creatures that phased in and out of reality, striking from the darkness.

Lesser Wyverns, malformed kin of true dragons, corrupted by Veldora's lingering aura.

Every battle forced me to push my Unique Skill further.

Reality Authority allowed me to alter the terrain, bending the battlefield to my advantage.

Spatial Subjugation let me blink short distances, creating gaps in combat and confusing my enemies.

Command Aura was especially useful—it forced weaker creatures to freeze in fear, giving me an instant advantage.

Energy Drain, however, was the real game-changer.

I learned to control the flow of absorption. At first, I was only able to take magicules in small amounts, but with every fight, I refined it.

I learned how to drain at a distance, latching onto multiple enemies at once.

I experimented with focused absorption, draining only specific aspects—stamina, raw magic, or even suppressing regeneration.

I found that with enough focus, I could sap energy from spells, dissipating enemy magic before it could harm me.

Each monster I defeated, each battle I survived, made my aura heavier—more refined.

The cave no longer felt like a place of fear.

It was my training ground.

And I was becoming the true apex predator.

On what I assumed was the fourth week, I faced something new.

A colossal drake, nearly three times my size, emerged from the shadows. Its scales shimmered dark violet, pulsing with the sheer amount of Veldora's magicules it had absorbed over the centuries.

Its eyes locked onto me, and unlike the others, it did not freeze under my Command Aura.

"Finally... a real challenge."

The beast roared, and I could feel the cavern tremble from its sheer force. It wasn't just some mindless mutated creature—it had instincts, intelligence, and more importantly... a terrifying amount of power.

The fight was brutal.

Every slash of its claws shattered stone.

Every breath attack was a torrent of pure destruction.

Every movement was faster than anything I had fought before.

I had never pushed Sovereign Dominion to its absolute limit before this battle.

And in the moment when I was pushed to the brink, something clicked.

A voice echoed in my mind.

Conditions met... Unique Skill: Sovereign Dominion is evolving...

My vision blurred as an immense surge of magicules erupted from within me, shaking the cavern walls and sending a pulse of raw energy outward.

For a brief moment, everything froze in place—the drake, the trembling cave, even the very flow of magic in the air.

And then the voice returned, louder and clearer than before.

The Unique Skill Sovereign Dominion evolved into Tyrannis, Lord of Absolute Sovereignty

The drake hesitated for a fraction of a second. And in that moment... it was over.

With a mere thought, I froze its movement completely, my aura surging with irrefutable authority.

A new instinct awakened within me.

With a simple gesture, I activated Energy Drain at full force—but this time, I didn't just sap its magicules.

I ripped them away completely.

The beast let out a deafening, agonized cry, its massive body withering, shrinking, until it collapsed into a lifeless husk before disintegrating entirely.

I exhaled slowly, my body still buzzing with raw power.

I checked my status.

Ultimate Skill: Tyrannis, Lord of Abosulte Sovereignty

Effect 1 – Sovereign Supremacy: The user's will becomes absolute over all beings below them. Grants the ability to dominate, paralyze, or command weaker entities with mere thought.

Effect 2 – Reality Enforcement: Allows the user to bend reality in localized areas, distorting the physical and magical laws of existence at will.

Effect 3 – Dimensional Authority: Full control over localized space, enabling instantaneous teleportation and the ability to create or erase small pocket dimensions.

Effect 4 – Absolute Drain: A perfected version of Energy Drain—capable of permanently stealing magicules, vitality, and even skills from defeated enemies.

Effect 5 – Tyrannical Aura: A passive effect that radiates supreme pressure, suppressing weaker beings, slowing their movements, and reducing their abilities drastically.

I slowly unclenched my fist, watching as the last remnants of the drake disintegrated into nothingness.

I took a step forward and immediately felt the difference.

My movements were smoother, faster, and far more controlled.

My magic perception was sharper, able to sense even the faintest fluctuations in the cave.

My very presence felt heavier, more commanding.

I clenched my hand again, and golden arcs of energy crackled around my fingers.

"This..." I muttered, staring at my hand in awe.

"This is power."

For the next few weeks, I roamed the cave, seeking stronger monsters to further master my new divinity.

I fought lesser wyverns and elemental wraiths, monsters far more powerful than those I had encountered before.

The magicules of the drake had supercharged the entire region, making the cave even more dangerous—but for me, it was nothing more than an opportunity.

Every battle was easier.

Every victory was more decisive.

I was becoming more efficient at wielding Tyrannis, draining enemies with pinpoint precision, and manipulating space around me like a god on a battlefield.

My status continued to skyrocket, and so did my confidence.

I was no longer merely a strong human.

I was now a force of nature, one that commanded reality itself.

After weeks of relentless combat and self-mastery, I returned to Veldora's chamber, stepping into the vast expanse where the Storm Dragon remained sealed.

The moment he sensed me, his golden eyes snapped open, gleaming with surprise.

"OHO? YOU ACTUALLY CAME BACK ALIVE?" His voice boomed, though there was a trace of genuine surprise behind his mocking tone.

I smirked, my gaze unwavering.

"Not just alive... but stronger."

Veldora's eyes narrowed slightly as he sensed the change. His gaze lingered on me, and for the first time, there was a flicker of something different—not mere amusement, but genuine curiosity and intrigue.

"Hmm... There's something different about you, Tenjou Yuuya." His voice was thoughtful, no longer just the playful tsundere tone.

"Your aura... it's heavier. More refined."

I stepped closer, my divine aura radiating subtly, making the very air hum with power.

Then, I met his gaze with a calm, confident smile.

"That's because I awakened." I raised my hand, and with a mere thought, Tyrannis flared to life, golden energy swirling around my fingertips like coiled lightning.

"I have an Ultimate Skill now.

Veldora's eyes widened slightly, then he threw his head back and let out his thunderous laugh.

"HAHAHAHA! TO THINK YOU'D ALREADY GAIN AN ULTIMATE SKILL!" His voice boomed with genuine delight.

"TENJOU YUUYA... YOU MIGHT ACTUALLY SURPRISE ME AFTER ALL!"

I smirked, clenching my fist with a surge of power.

"Heh. You better believe it."
