"Black King Nidhogg."
Like a deity, Uchiha Sogetsu's eyes seemed to contain blazing lightning and golden flames. His cold, indifferent voice echoed through the sky: "Don't die so easily!"
Indra's Arrow!
In the next moment, the Susanoo suddenly gathered strength and threw the destructive lightning bolt.
The sudden burst of intense light immediately split the sky!
The dazzling light even stole the brilliance of the world, plunging everything into a gray-white, dead silence.
The Black King suddenly became alert, feeling a sharp, almost tangible pain, once again sensing the overwhelming danger of being on the brink of death.
In just a moment of distraction, the Black King snapped out of it and saw a beam of light, like a comet trailing its fiery tail, or like thunder descending from the sky.
It was so radiant, interwoven with lightning and golden flames, that it even outshone the sun!
Boom!!!
Finally, Indra's Arrow hit the Black King.
However, due to an invisible barrier, the arrow was still half an inch away from the Black King. But the barrier was breaking apart.
Until, it completely shattered, and the Indra's Arrow exploded.
The sharp sonic boom that pierced the eardrums sounded, and the Black King's chest was pierced.
The friction between the Indra's Arrow and the air created sparks that vaporized the surrounding matter.
The remaining force continued along its path, creating a vacuum channel hundreds of kilometers long!
Blood surged wildly, the Black King's blood splattered high into the sky, and screams echoed through the air above the island.
Then, the massive body of the Black King crashed down, slamming into the consciousness island, raising a cloud of dust hundreds of meters high.
With a pierced chest, the Black King finally realized that the enemy before him was terrifying!
He no longer held back, opening his mouth to chant the ancient and mysterious dragon language.
Word Soul: Rhine!
There was no need for any preparation time; the moment he spoke, it was already a "final move."
"Is it finally happening?"
Uchiha Sogetsu not only had no intention of stopping it but was also watching with great interest.
The elements within a few hundred kilometers around them were instantly drained to a "vacuum" state, and it was as if tangible elemental currents gathered in the sky, rushing like a flood that had broken through a dam.
Uchiha Sogetsu activated his Spirit Vision, and what he saw was a scene of colorful streams, constantly surging toward the Black King.
The increasingly violent elemental currents formed a giant vortex in the sky, and inside, the fast-moving elements collided fiercely.
The flash-melting reactions acted like catalysts, causing the elements within the domain to accelerate friction.
The temperature above the entire island rose rapidly, like a pressure cooker with increasing pressure.
"Is this the ultimate Word Soul?"
Uchiha Sogetsu observed carefully. Even though he possessed the authority of the White King, the ultimate Word Soul wasn't that simple.
Each ultimate Word Soul was the pinnacle of alchemy, the utmost use of authority, and his use of it seemed more like a crude imitation.
Finally, he could see the real 'ultimate Word Soul' with his own eyes!
Uchiha Sogetsu's right eye glowed crimson, as though a windmill were spinning—his long-unused Mangekyō Sharingan.
Eye Technique: Mugen Rikai!
Every movement of the Black King, even the strength of his chant and the direction of the controlled elements, all appeared in Sogetsu's eyes.
"I see."
In just a few seconds, Uchiha Sogetsu 'understood' what was meant by the ultimate Word Soul.
At that moment, the chant of the Black King finally reached its end.
Elemental turbulence erupted in a dazzling display of brilliance due to the flash-melting effect.
At this instant, it was as if thousands of nuclear bombs had exploded, releasing enormous orbs of light that even outshone the sun.
Boom——!!!
Time seemed to stretch infinitely, and in the silence, only the sound of a deafening roar that tore through the sky could be heard!
It was like the roar of an ancient behemoth, shaking the sea of subconsciousness. The islands of consciousness swayed in the storm, seemingly on the verge of shattering at any moment.
The light ball, with a diameter of over 100 kilometers, emitted a blinding white brilliance that was even brighter than any star, more dazzling than any sunrise, scattering the dark clouds above the islands of consciousness.
The intense heat wave and shockwave spread out in all directions.
In the explosion's core region, the temperature reached that of a star's core!
With a terrifying heat of 15 million degrees Celsius, it was enough to vaporize or even atomize any material instantly. It was the pinnacle of Word Souls, the peak of destruction!
As the light ball gradually dimmed, the air inside it evaporated, forming a vacuum-like area.
The external air rushed in at high speed, causing violent waves, with layers of air currents surging like a tsunami!
The intense nuclear explosion triggered by Rhine engulfed an area of several hundred kilometers.
The massive ball of bright white light resembled the radiant glow of countless suns from Indian mythology, exploding in the sky all at once.
The temperature, close to the core of a star, obliterated everything within its reach—both tangible and intangible—completely annihilated!
From this, it's easy to understand why 'Rhine's' danger level is considered world-ending!
In the real world, such a vast explosion would instantly turn a city of millions into nothing but ashes.
The most powerful hydrogen bomb humanity has created, if we disregard the nuclear radiation, might not even cause one-third of the destruction 'Rhine' could cause.
And don't forget, this is still an incomplete version of the Black King's authority.
If it were in the era of the ancient past, when the Black Emperor still reigned, it's hard to imagine how terrifying the scene would be!
Perhaps the mythological stories passed down in human history aren't just 'stories.'
Perhaps they were real events that occurred at some point but have been deliberately hidden or altered over time.
The fierce winds and waves caused by 'Rhine' lasted for a full quarter of an hour before slowly dying down.
The Black King, at the center of the explosion, was surrounded by dark membrane wings, looking like a giant egg.
Around him, a barrier was placed, as if forged from gold, with ancient dragon runes flowing on its surface, completely isolating the explosion from the outside.
Mental Power: Diamond Barrier!
With the purity of the Black King's bloodline, the effect of his mental power naturally far surpassed that of any lowly hybrid.
