The Dragon Regin

Walking out of the Celestial Palace, Heisenberg found Heimdall standing beside the Bifröst Bridge, overseeing the Einherjar as they continued their repair work.

Asgard lacked neither the materials nor the expertise to rebuild the Bifröst. As the most crucial transportation tool and star-destroying weapon of the Aesir, Odin had long stockpiled emergency resources for the bridge.

Though, Odin likely never imagined his own son would be the one to destroy it.

Noticing Heisenberg's approach, Heimdall straightened up, setting aside the light-energy crystal in his arms.

He brushed the glowing dust from his body and bowed slightly to Heisenberg.

"Your Majesty."

"Good afternoon, Heimdall. Give me Surtur's location."

"As you command, Your Majesty. Surtur resides in an underground lair in Muspelheim, accompanied by the flame dragon Regin.

However, they are no match for you. May your journey be victorious."

"Hmm."

Heisenberg nodded, placing a hand on Heimdall's shoulder. Moments later, a faint location materialized in his mind.

Heimdall was marking Surtur's lair for him!

The rainbow light descended, and Heisenberg vanished instantly.

…

Meanwhile, in Muspelheim.

The towering fire giant Surtur sat on his decaying throne, brooding over his life's misfortunes.

As the master of flames in the Nine Realms, Surtur once lived a life beyond imagination.

He rode his flame chariot across infinite worlds, wielding his great sword to battle countless warriors. He was the offspring of fire, its very embodiment—arrogant and domineering!

Until… he met someone even more arrogant!

Surtur could never forget the man who fought him for days and nights, defeated him, and then uttered the most hypocritical words he'd ever heard!

That man had said, "Surtur, you're too dangerous. I must seal you away!"

And so, Surtur and the flame dragon Regin were sealed in a cavern eight kilometers beneath Muspelheim, never to step outside again.

To this day, Surtur couldn't forget that man, nor the rainbow light that accompanied his arrival.

That light…

"Hmm?"

Surtur froze, staring blankly at a spot thirty meters ahead.

That rainbow light…

How the hell had it returned?!

Boom!

Surtur leaped from his crude throne, brandishing his weapon and glaring at the light.

The next second, the rainbow light dissipated, revealing Heisenberg, smiling curiously at his surroundings.

"Heavy sulfur smell. Doesn't feel like the realm of fire, more like hell."

Heisenberg waved his hand, brushing away the dust drifting toward him.

"Plenty of flame creatures around. Look at them—their veins flow with lava. Impressive.

Too bad they're uncontrollable and lack order. Otherwise, they'd make excellent soldiers… or cannon fodder."

"Who are you, intruder?!"

Surtur's booming voice interrupted Heisenberg's musings. Heisenberg turned to face him.

Without his flames, the diminished Surtur lacked any imposing presence, leaving Heisenberg utterly unmoved.

Surtur continued to question Heisenberg.

"Answer me, foolish intruder! Who are you? Where is Odin? Speak!"

Boom!

Surtur roared, charging from his throne.

He raised his great sword, dragging the chains binding his ankles, and stopped two meters from Heisenberg.

The massive Twilight Blade pointed at Heisenberg's head. Heisenberg smiled, examining the blade's material.

The incredibly hard divine metal radiated intense flame energy, its fervor resonating deeply with Heisenberg.

"This is it. Perfect!"

Heisenberg nodded in satisfaction. Hela and Frigga's advice had been spot on. As the master of the sun, Heisenberg appreciated this metal.

But Heisenberg's nonchalance infuriated Surtur. Even his sword trembled slightly in his grip.

"This is how it is, you damned Aesir! Always so arrogant and rude!!!

Look at me, you Asgardian god! Tell me where Odin is! Tell me your relation to him!!!

Or you'll face your death…"

Before Surtur could finish, he raised the Twilight Blade high.

Heisenberg calmly watched as Surtur swung the blade toward him, unmoving.

As Surtur brought the blade down, he shouted his final words.

"Face your death!!!"

Thud!

A heavy, resounding impact, like the tolling of an ancient temple bell.

The Twilight Blade slammed into Heisenberg's left shoulder!

Surtur stared in disbelief at Heisenberg, then at his own sword.

Had he grown weak? Or lost his strength?

Why hadn't his strike even made the man flinch?

I know you're strong now, but… couldn't you at least react a little?!

Standing still like a turtle—what the hell?!

Whoosh!

Surtur pulled the blade from Heisenberg's shoulder and set it aside.

He waved his hand, dispersing the flame demons gathering nearby.

Watching Heisenberg's unchanged smile, Surtur's massive jaw slowly opened and closed.

After a moment, he spoke.

"Welcome, guest from Asgard. Your arrival honors me greatly.

It's been too long since I've seen any of you. My friends, Asgard and Muspelheim were always the best of allies!

Your king, Odin, and I were inseparable. This very house was his gift to me. But we haven't met in ages—such a shame.

Are you Odin's child? I've heard of his descendant, Thor, the famed Thunder God. I've never had the chance to meet him.

Now that I see you, I understand why your name echoes through the Nine Realms. Only a warrior like you deserves Asgard's throne. You must be Thor, right?!"

Surtur enthusiastically extended his hand, gesturing toward his throne.

The lava on the ground rapidly formed a table and chairs opposite his throne.

"Please, sit! Young and mighty god, I, Surtur, love making friends.

Let's drink Muspelheim's Flameheart Wine together. I'll tell you stories of Odin's past, haha!"

Having exhausted his polite words, Surtur silently awaited Heisenberg's response.

Heisenberg, under Surtur's tense gaze, brushed the dust from his shoulder and asked,

"You and Odin were close?"

Surtur quickly replied, "Of course! We were so close we could've shared a divine seat!

And I have proof—look around! He gave me all this!"

"Oh?"

Heisenberg glanced meaningfully at Surtur and softly said,

"Then I'm afraid I have bad news. I'm not Thor. You can call me Heisenberg.

As for your best friend Odin…

He's dead. I killed him!"

Surtur's eyes widened, and he roared,

"Look at this! This cramped space, this stifling cavern, this life never seeing the light—all his gifts to me!

He took my flames, my very essence, leaving me cold to this day!

He even chained me here, making me look like a fallen dragon!!!"

From the depths of the cavern, a massive dragon's head suddenly emerged.

Regin first looked around wildly, then, upon seeing Heisenberg, charged forward, ready to fight!

At that moment, Surtur wiped the lava from his head and pushed Regin's head to the ground, forcing him down.

Regin, confused, saw Surtur force a smile at Heisenberg.

"After Odin's brutal cleansing of the Nine Realms, Regin is the last dragon!

Care to try riding a dragon, my lord?"

As soon as Surtur finished, Regin struggled fiercely.

He was a descendant of Typhon! No one had the right to use him as a mount. No one could ride him—no one!!!

Regin's strength was immense. If Surtur still had his flames, he could easily subdue the dragon.

But now, Regin easily broke free.

He flipped over and lunged at Heisenberg!

His massive wings didn't flap like a typical dragon's but remained pressed against his body.

Instead, the tips of his wings unleashed rocket-like flames, propelling him forward like a missile!

His speed was astonishing—even Thor might not match it!

Though Regin's neck was still bound by heavy chains, they were long, and Heisenberg was too close.

In an instant, Regin reached Heisenberg!

Facing the gaping maw before him, Heisenberg blinked, smiling with interest.

This dragon was so cool, especially with his rocket-like propulsion—adorable!

Heisenberg gently reached out, grabbing the chain around Regin's neck.

The next second, Regin's neck slammed into Heisenberg's palm, and the dragon howled, flipping over.

Boom!

Regin's massive body crashed to the ground, shaking Surtur's lair violently.

The natural lava stalactites Surtur cherished most shattered in countless pieces.

Yet Surtur couldn't utter a word.

When you witness a beast you cannot hope to match being toyed with like a cricket, the gap between you becomes painfully clear…

In this eerie silence, Heisenberg's eyes widened.

An intensely scorching gaze made Surtur's body tremble. The heat of that light far exceeded even the Eternal Flame he once possessed!

The fiery gaze burned through the chains binding Regin, offering the dragon, who had slammed his throat and rolled his eyes, a moment of relief.

Looking at the now-free Regin, Heisenberg nodded in satisfaction. He casually lifted Regin, setting him aside in a cute, crouching pose.

Taking out his phone—before Muspelheim's heat could melt it—Heisenberg snapped a fantastic selfie with Regin.

Then, pocketing his phone, he turned to Surtur, standing silently in the distance.

The next second…

Surtur, his body dripping with magma, offered Heisenberg an awkward smile.

He raised his right hand, clenched his fist, and roared,

"I am Surtur, and I will have my vengeance against Odin!!!"
