Amaterasu: World-Burning

Inside the core chamber of the fortress, the Large Mangekyo containing the power of [Amaterasu: World Burning] was slowly turning, its deep red patterns seemingly waiting for its master to return.

Waiting for the moment when I am awakened.

The rainbow light receded, Tsukuyomi Space, like a cloak being gathered up, silently dissipated into the air.

Uchiha Jun group landed safely inside the core laboratory of the Sky Fortress.

The familiar cool touch of the steel deck beneath their feet, the low hum of the surrounding instruments and equipment, and the faint, fishy smell of Chakra- conducting fluid in the air—the smell they had before they left—everything was unchanged.

In just a few tens of minutes, they traversed thousands of kilometers, severed One-Tails tail of Shukaku, the strongest weapon of war in the Land of Wind, and took it away. They also intercepted the Fourth Kazekage's Kekkei Genkai and tested various abilities of the Tsukuyomi Space. The gains from this trip are enough to cause a dramatic change in the strategic landscape of the entire Shinobi World.

At this moment, everyone's attention was focused on the huge culture device in the very center of the laboratory.

It was a cylindrical cultivation device about three meters high and five meters in diameter. Its outer shell was made of a special Chakra-Conducting Alloy, and its surface was covered with densely packed Sealing Jutsu techniques, constantly flashing with a ghostly blue light.

Inside the device, there was a pale green culture medium that was bubbling away.

And in the very center of the culture medium—a spherical, deep red Mangekyo —was quietly suspended.

Its size is comparable to that of the Tsukuyomi Mangekyo, about one meter in diameter, requiring two people to barely encircle it.

However, its patterns are completely different from those of the Tsukuyomi Mangekyo.

The patterns on the Tsukuyomi Mangekyo are concentric circles like ripples on water, layer upon layer, giving a sense of depth, inclusiveness, and as if it can devour everything.

The Amaterasu Mangekyo in front of us—its patterns are radial cracks like flames!

The cracks extended outward from the core of the Mangekyo, like cracked ceramic or magma surging deep within the earth's crust, meandering across the deep red surface, exuding an extreme, dangerous, and violent aura that seemed ready to explode at any moment.

Just by standing in front of the cultivation device, Uchiha Jun could feel the scorching heat emanating from it.

It's not a physical temperature, but a burning sensation on a mental level.

--Transformed into Sage Transformation!

The next moment, Uchiha Jun entered Sage Transformation Mode, and the interference from his eye power immediately disappeared without a trace, forcefully suppressed by Uchiha Jun.

"The pupillary activity in the culture medium has reached 100%."

Hiruko strode to the control panel of the incubation device, her fingers flying across the screen to display rows of data. "All Sealing Jutsu are stable, and there are no abnormal fluctuations in the internal Chakra flow... The fusion of Amaterasu Mangekyo is completely complete!"

She looked up at Uchiha Jun, her eyes gleaming with excitement. "Boss, it's ready."

Ready.

These four words, like a pebble thrown into a calm lake, created ripples in the laboratory.

Orochimaru licked his lips, his snake-like eyes gleaming with anticipation.

Tobirama Senju crossed his arms, his gaze grave.

Uchiha Jun slowly walked to the cultivation device.

Raise your right hand and press it against the transparent outer wall of the culture device.

Through the specially made Chakra- conducting glass, he could clearly feel the pulsation of the Amaterasu Mangekyo.

That kind of pulse is not as steady, profound, or as natural as breathing as Tsukuyomi Mangekyo.

Rather, it was a violent, intense pulsation, like a heart pounding wildly.

"Open the culture device."

Hiruko deep breath and pressed a series of commands on the console.

"Buzz--"

The culture device emitted a low rumble, and its transparent outer wall began to slowly open to both sides.

The pale green culture medium evaporated rapidly upon contact with air, turning into wisps of white mist that diffused in all directions.

In the mist, the deep red light of Amaterasu Mangekyo grew brighter and brighter.

It's getting brighter and brighter.

until--

"Thump!"

A deafening roar, like a heartbeat, exploded in the laboratory!

Everyone's heart skipped a beat in that instant!

That's the pulse of Amaterasu Mangekyo.

As if it had come to life, the cracks that resembled flames began to slowly rotate, emanating a suffocating sense of oppression.

"Thump--!"

The heart-pounding roar echoed continuously in the laboratory, growing more intense with each resounding thud.

The deep red patterns on the Amaterasu Mangekyo began to spin wildly, no longer a slow, rhythmic pulsation, but rather—going berserk!

"Buzzing----"

The Chakra-Conducting Alloy inside the cultivation device emitted a piercing shriek, and the Sealing Jutsu on its surface shattered one after another, flashing a dark blue light rapidly, like a dam about to collapse.

"Not good!" Hiruko's expression changed drastically, and he frantically operated the control panel. "The threshold for the Sealing Jutsu's tolerance is dropping rapidly! The Amaterasu Mangekyo's eye power activity has exceeded 120%—it's rejecting the fusion of the White Zetsu Cells!"

Orochimaru's pupils contracted slightly, his voice low and urgent. "It... is resisting."

Perhaps the process of mastering the large Tsukuyomi Mangekyo was too smooth, so when the large Amaterasu Mangekyo suddenly rioted, everyone present was shocked.

"No." Tobirama Senju analyzed from the side, his hands already forming hand seals, ready to unleash Ninjutsu at any moment.

"It's searching for a host. It seems the power of the Large Mangekyo has matured to the point of developing instinctive consciousness. It's choosing someone capable of bearing it—if it can't be suppressed, it will devour the holder!"

Before the words had even finished --

"Boom--!!"

The main entrance to the culture device was blasted open by an invisible force!

The pale green culture medium evaporated into a cloud of white mist in an instant, while the deep red Amaterasu Mangekyo, like a ferocious beast breaking free of its shackles, slowly rose into the air.

The temperature in the entire laboratory soared in an instant.

It's not a physical high temperature, but a burning sensation on a mental level.

"It's about to unleash its Dōjutsu!" Orochimaru shouted.

The next instant, the patterns on the Amaterasu Mangekyo began to light up rapidly—

At that critical moment—

"--Don't be so presumptuous."

Uchiha Jun's voice was eerily calm.

The next moment, a completely different aura erupted from his body!

Sage Transformation--!

Deep within Uchiha Jun's eyes, faint golden patterns emerged, contrasting beautifully with the crimson of his Sharingan.

Faint, porcelain-like white lines appeared on his skin—marks of the perfect fusion of Natural Energy and Chakra.

Her black hair moved without wind, and the ends were tinged with a transparent silvery-white.

The air in the entire laboratory seemed to freeze in that instant.

If the aura emanating from the Amaterasu Mangekyo is a violent, destructive fire that intends to burn everything to ashes.

The aura emanating from Uchiha Jun at this moment was that of a majestic, unshakeable mountain that had stood firm since ancient times.

Senjutsu Chakra.

It is a power that transcends ordinary Chakra; it is a higher level of power generated by the perfect fusion of Natural Energy, spiritual energy, and physical energy.

"Buzz--!"

Uchiha Jun raised his right hand, palm up, and gently clenched his fist.

An invisible, boundless Senjutsu Chakra surged forth from his body like a tide, transforming into a giant, semi-transparent Chakra hand that grasped the rampaging Amaterasu Mangekyo in mid-air.

Grab it in one swift motion, and refine it instantly!

"What?!" Hiruko widened.

The moment the Large Mangekyo was enveloped by the Senjutsu Chakra Hand, it erupted with even more ferocious resistance!

The crimson flame patterns spun wildly, and jet-black flames erupted from the core of the Mangekyo, attempting to burn through the Senjutsu Chakra Hand!

But the next moment, he gripped it tightly.

The hand imbued with Senjutsu Chakra suddenly tightened!

The patterns on the Amaterasu Mangekyo flickered violently a few times.

Then--

It slowly and quietly, like a wanderer who has finally found his home, floated down from mid-air and hovered above Uchiha Jun's palm.

The deep red light softened and became gentle.

Just like the Tsukuyomi Mangekyo from before.

"It's a success..." Hiruko, slumping into the control panel, his forehead covered in cold sweat. "Successfully suppressed..."

Orochimaru licked his lips, a complex light flashing in his snake-like eyes. "Forcibly suppressing the rampaging Mangekyou Mangekyo with Senjutsu Chakra... is it a characteristic of Senjutsu Chakra, or Jun-kun's power?"

"Both are possible!"

Tobirama Senju spoke from the side, a deep, indescribable light flashing in his eyes.

Uchiha Jun slowly opened his palm, and the Amaterasu Mangekyo floated quietly in his palm, the deep red flame patterns slowly rotating, emitting a gentle yet powerful ocular aura.

Close your eyes and immerse your consciousness in the core of the Mangekyo.

The next moment--

Information about the [Amaterasu: World Burning] Dōjutsu flooded into his mind like a tidal wave.

--Summon conceptual-level black flames, lock onto the target, and incinerate it at the level of existence.

--The shape, range, and intensity of the flames can be freely controlled; they can be condensed into a single point or expanded into World-Burning Domain.

Those whose targets are consumed by the flames of the world-burning inferno will suffer soul-destroying damage.

Uchiha Jun slowly opened his eyes, the smile on his lips growing deeper and deeper.

" --Amaterasu ·Burn the World."

Above his palm, the Mangekyo slowly rose into the air, creating a wondrous resonance with his left eye.

The next moment, flame crack patterns identical to Amaterasu Mangekyo Sharingan appeared in Uchiha Jun's left pupil!

And in his right pupil—the concentric circles of water ripples from the Tsukuyomi Mangekyo appeared!

Awaken both eyes simultaneously!

In the laboratory, an invisible, unprecedented sense of oppression swept outwards like a tidal wave!

Everyone took a step back at the same time.

At the same time, a familiar, cold, mechanical voice suddenly rang in Uchiha Jun's mind!

[Bite--!]

[Detection indicates that the host has successfully mastered two Large Mangekyo — the Tsukuyomi Mangekyo (Spiritual/Yin) and the Amaterasu Mangekyo (Material/Yang).]

[Conditions met! Hidden achievement quest [Large Mangekyo - Tsukuyomi - Amaterasu] is complete!]

Uchiha Jun looked at the rows of rewards on the panel, even with his usual composure, he couldn't help but raise an eyebrow slightly.

The rewards for an SSS rating are indeed outrageously generous.

If these rewards were available, the battle between Ōtsutsuki Hamura on the moon could probably have ended much faster!

Uchiha Jun closed the system panel and held the deep red Amaterasu Mangekyo steadily in his palm.

He glanced around at everyone in the laboratory, his voice calm.

"Let's go to the deck."

"--A newly acquired 'weapon' should be tested for its sharpness first."

The group walked through the steel corridors of the Sky Fortress, took an elevator, and arrived at the open-air deck at the top of the fortress.

The wind howled through the high sky, carrying a biting chill from thousands of meters above the clouds.

Beneath my feet stretches an endless sea of clouds, while in the distance, the afterglow of the setting sun paints the sky a golden-red hue.

Uchiha Jun stood at the very front, his long robes fluttering in the wind high above.

"Amaterasu."

He raised his left hand, palm up, and the Amaterasu Mangekyo slowly floated up, resonating with his left eye.

"Target--"

Uchiha Jun's gaze pierced through the sea of clouds and landed on a towering black mountain peak a dozen kilometers away.

It was a barren rocky mountain, devoid of any vegetation, with only exposed black rock layers, about three or four hundred meters high, standing like a giant stone pillar among the mountains.

"That mountain."

Orochimaru followed his gaze, his snake-like pupils narrowing slightly as he exclaimed in surprise, "More than ten kilometers... At that distance, ordinary Ninjutsu can't even reach them."

"I'm afraid only Tailed Beast Ball can allow you to touch it, and only Tailed Beasts of at least the level of the Eight-Tails or Nine-Tails can do that!"

"The range of Large Mangekyo cannot be measured by ordinary standards." Tobirama Senju his arms, his gaze fixed intently on the floating Mangekyo. "If it can truly achieve ultra-long-range precision strikes, then its strategic value will surpass that of any Tailed Beasts!"

Meanwhile, Hiruko had already quickly set up the observation equipment on the deck, and streams of data flashed rapidly across the screen. "Observation system in place, data transmission complete... Ready to launch at any time!"

Amaterasu ·Burn the World--!

"Buzz--!"

The Amaterasu Mangekyo suddenly lit up, its deep red flame crackles spinning wildly, radiating a suffocating sense of oppression!

Immediately afterwards--

An extremely thin beam of black light, almost invisible to the naked eye, shot out from the core of the Mangekyo!

The beam of light, as thin as a hair, was faster than sound and beyond the limits of visual perception—like a black needle, it pierced through a space of more than ten kilometers in an instant, hitting the summit of that black mountain with pinpoint accuracy!

It took less than a breath.

"Boom--!!!!!"

The next second, black flames exploded on a mountain peak more than ten kilometers away!

Soaring into the sky!

That scene was beyond what could be described as "burning".

The black flames, like a living torrent, swept and spread from the mountaintop outwards. Wherever they passed, the black rocks were instantly melted into red-hot magma, and then instantly evaporated into white smoke!

The entire mountain, starting from the summit, began to collapse, melt, and disappear, like a candle being crushed by an invisible giant hand!

Three hundred meters, two hundred meters, one hundred meters --

In less than half a minute, the black rock mountain, which was about 400 meters high, was melted and evaporated, losing more than 300 meters of its height!

Less than a hundred meters of the scorched red-hot rock base remained, still emitting thick smoke, and the air was filled with a scorching smell, as if even the air itself had been burned through.

"This... this is amazing..." Hiruko's lips trembled, her fingers pressed tightly against the observation equipment, her voice almost distorted.

"From launch to impact, it took less than 0.3 seconds... covering a distance of over ten kilometers... and--"

Her voice trembled with disbelief.

"Moreover, that mountain was made of granite... a rock with a melting point above 1200 degrees Celsius... yet Amaterasu's flames completely melted and evaporated it in just half a minute... This means the temperature of Amaterasu: World-Burning flames..."

"No." Uchiha Jun slowly lowered his hand, the flame pattern in his left eye slowly rotating, a faint smile curving his lips. "Amaterasu: World-Burning Flame doesn't burn its target with heat."

Uchiha Jun paused, his voice calm and deep:

"--It directly erases the target's material structure from the level of 'existence'."

Temperature is just one of the physical phenomena produced during combustion, not its essence.

Orochimaru's snake-like eyes gleamed with unprecedented excitement. "Directly erasing existence... In other words, things destroyed by this kind of flame can't even be treated with Ninjutsu or regeneration Ninjutsu?"

"Theoretically, yes." Uchiha Jun nodded. "A target destroyed by Amaterasu: World Burning will be completely erased on a material level—no conventional Medical Ninjutsu or repair technique can restore it to its original state."

These words silenced everyone present.

Hiruko a deep breath and slowly said, "This power... surpasses any Fire Release Ninjutsu I know. It even... surpasses the First Hokage's Wood Release."

"With a range of over ten kilometers, an accuracy of half a meter, and enough power to melt a rocky mountain hundreds of meters high in a short time—"

"This is no longer within the scope of ' Ninjutsu.' This is—a strategic weapon."

Uchiha Jun did not deny it, but calmly withdrew the Amaterasu Mangekyo, letting it float beside him.

That evening, the conference room in the Sky Fortress was brightly lit.

A huge round table was placed in the center of the conference room, on which was projected a three-dimensional structural diagram of the Sky Fortress. Chakra- powered projectors clearly presented every detail of the fortress in mid-air.

Uchiha Jun sat in the main seat, with Tobirama Senju, Orochimaru, Hiruko, Seimei, Uchiha Hikari, and En Oyashiro seated on his left and right sides, respectively.

Through remote projection technology, a figure appeared in the empty seat next to the conference table—

Ōtsutsuki Ha, the current patriarch of the Moon Ōtsutsuki Clan, the coordinator of the White Zetsu Corps, and the overall person in charge of engineering and logistics.

"Everyone's here," Uchiha Jun said, his tone calm and direct. "Let's get down to business."

Uchiha Jun raised his hand, and two Mangekyo Sharingan projections appeared above the round table—one was the concentric circles of Tsukuyomi, and the other was the flame cracks of Amaterasu.

"I called you all here today to discuss something—"

"--Integrate the Tsukuyomi Mangekyo and Amaterasu Mangekyo into the Sky Fortress's defense system."

The meeting room fell silent for a moment as soon as he finished speaking.

Scorpion spoke first, his voice hoarse but tinged with interest. "Connecting to the defense system... exactly how does that work?"

"It's very simple." Uchiha Jun stretched out his finger and drew a circle on the projection.

"The biggest weakness of the Sky Fortress right now is that when faced with large-scale Ninjutsu attacks, it can only rely on the Chakra-Conducting Alloy of its outer shell to withstand them, or rely on its mobility to evade them."

"But what if we applied the power of Tsukuyomi Mangekyo to cover the entire outer shell of the fortress?"

"The moment the enemy's Ninjutsu attack touches the fortress's outer shell, Tsukuyomi's eye power will 'illusory' it—allowing the Ninjutsu's attack effect to be transferred into the Tsukuyomi Space and digested the moment it touches the fortress, while the fortress itself remains unharmed."

Seimei's eyes lit up. "Using the mental interference properties of the Tsukuyomi Space, physical attacks are transformed into mental illusions... In other words, when the enemy's Ninjutsu hits the fortress, it's like hitting a phantom created by Genjutsu?"

"That's right." Uchiha Jun nodded. "The ability of the Tsukuyomi Mangekyo is essentially 'mental interference with matter.' If this power is used in reverse—using mental interference to 'nullify' attacks on the material level—theoretically, it is possible."

Seimei paused for a moment, then slowly said, "This idea is theoretically feasible, but several technical issues need to be resolved."

"First, the range of Tsukuyomi Mangekyo's Mangekyou Sharingan's eye power— the Tsukuyomi World the size of a football field—is not even in the same league as the amount of eye power required to cover the defensive layer of an entire Sky Fortress."

"Secondly, response speed. The enemy's Ninjutsu attacks are extremely fast. The fortress's defensive layers must complete the illusion detection the instant they come into contact with the attack; otherwise, the fortress's outer shell will still be damaged."

"Thirdly, stability. To stably integrate the Mangekyo Sharingan's power into the fortress's defensive spell network, a completely new Chakra conduction system is needed."

Uchiha Jun looked at Seimei, a slight smile playing on his lips, "That's why I called you here."

He held up two fingers. "First, regarding the power of the Tsukuyomi Mangekyo, I've already arranged Energy Storage Array —one hundred and twenty pairs of Three-Tomoe Sharingan as power batteries, which can support the continuous operation of the Tsukuyomi Mangekyo."

"Secondly, response speed and stability--"

Uchiha Jun looked at Sasori and En Oyashiro.

"--This is your job."

"I'm giving you a budget of two billion."
