Naruto: Uchiha Youngjo's Konoha Spring

Chapter 231 Sasuke's Mangekyō
A deafening roar echoed throughout the Valley of the End, the entire earth groaning and cracking under the explosion! A tangible shockwave, forming a ring, exploded outwards at supersonic speed! Wherever it passed, the air was compressed into white walls of vapor, and the raging waterfalls beneath were abruptly severed, whipping up towering waves! Countless tons of water were instantly evaporated into scorching white steam, then brutally torn apart by the shockwave! The stone statues of Hashirama Senju and Madara Uchiha, which had stood there since that battle, enduring the daily ravages of wind and rain yet remaining unmoved, shattered like fragile plaster statues from the neck up under this cataclysmic impact! Countless massive fragments of rock were hurled high into the air like a meteor shower, then crashed back down into the churning steam and towering waves below!

At the heart of this destructive storm, Sasuke's vision was a blinding white and chaotic blur! The immense impact made his bones groan! His right arm was writhing in excruciating pain, as if it would be utterly crushed by the raging golden power in the next second! The lightning of Chidori, under the endless spinning of the Rasengan and the terrifying brute force of the Nine-Tails' chakra, emitted a piercing wail, its light rapidly dimming!

Was he going to lose? Was his arm going to break? No! Absolutely not! How could he lose to this loser who left without permission! He was going to break this guy's legs and take him back to the village! The loneliness of being abandoned, the anger of being left alone, burned in his heart like poisonous fire!

"Ughh ...

A desperate and unwilling roar, originating from the deepest part of his soul, burst forth from Sasuke's throat! The extreme desire for power that erupted in the face of despair, the obsession with turning the tide, was like a red-hot iron and a special chakra flowing from his body, fiercely burning into the depths of his wildly spinning three-tomoe Sharingan!
“Crack—!”

A crisp sound, seemingly from the depths of his soul, that only he could hear!

The three magatama that were spinning wildly in his vision suddenly froze, and then, in a fraction of a second, they seemed to be pulled, twisted, and exploded by an invisible force! An indescribable pain instantly pierced through his brain! At the center of the exploded crimson fragments, a brand new, bizarre, and complex pattern instantly formed and solidified!
The pattern was deep and cold, carrying a mysterious and ominous quality, as if it could see through the trajectory of fate. The instant the pattern took shape, a new, cold, and powerful torrent of ocular power, like a glacier that had been dormant for millennia suddenly collapsing, crashed into Sasuke's eyes and flowed throughout his entire body! The Mangekyou Sharingan!

The world suddenly changed in his eyes! The flow of energy became clearer than ever before, and every minute detail of the chakra circulation in Naruto's ferocious Rasengan was as clear as the lines on his palm! Furthermore, a cold power instantly awakened and condensed within the Chidori in his right arm, which was on the verge of collapse!
“Swish——!”

A tiny yet perfectly condensed arc of black electricity, like a blade from the underworld slicing through chaos, suddenly burst forth from the core of Chidori! Ignoring the Rasengan's high-speed spinning defense, it carried a power of annihilation, instantly piercing through the golden chakra's outer shell and heading straight for the core of Naruto's Rasengan!
"What?!" Naruto's eerie vertical pupils suddenly contracted, and his Nine-Tails Mode senses instantly detected the danger of that dark arc of electricity! It was a power that could erode and disintegrate the very essence of chakra! He instinctively wanted to withdraw, but the momentum of the all-out clash was unstoppable!

The moment the jet-black electric arc pierced the core of the Rasengan was like a drop of cold water being poured into a boiling oil pan!
"Bang——!!!"

The second explosion occurred! It wasn't an external shock, but rather an energy explosion triggered by the black arc of electricity eroding and destroying the internal structure of the Rasengan! The highly compressed chakra lost its restraint and exploded uncontrollably in Naruto's palm!

"Pfft!" Naruto was struck hard, spitting out a mouthful of blood. He was blasted backward by his out-of-control ninjutsu! His golden chakra cloak fluctuated violently, flickering and almost dissipating!
Sasuke was also violently thrown back by the force of the explosion, crashing heavily into a large, not yet completely collapsed rock wall behind him, creating a spiderweb-like crater and sending debris raining down. He knelt on one knee, panting heavily, the wound on his left arm and the excruciating pain in his right arm tearing at his nerves, his brain spinning and throbbing from the activation of the Mangekyou Sharingan. But he suddenly raised his head, his newly formed eyes, flowing with cold and eerie patterns, locking onto the flying Naruto, his pupil power like a tangible cold current, piercing through the billowing smoke and mist.

Smoke and water vapor, like a tattered curtain, slowly settled and tore apart amidst the violent aftershocks of energy. The Valley of the End seemed to have witnessed a divine war, leaving it in ruins. The colossal stone statues were reduced to broken torsos, and the once roaring waterfall was blasted apart, forming a massive water vapor cavity from which murky water gathered again, emitting a mournful sound.

Naruto staggered and steadied himself on a massive rock jutting out of the water in the distance. Blood stained the corner of his mouth, and his golden chakra cloak flickered like a candle in the wind. His eerie vertical pupils reflected Sasuke's cold, unfamiliar Mangekyou Sharingan, which held a terrifying new power. His heavy breathing aggravated the pain in his chest; each breath carried the stench of blood. He slowly raised his right hand; his palm was charred and mangled—evidence of the injury inflicted by his out-of-control Rasengan. Sasuke, leaning against the cold rock wall, endured the tearing pain in his left arm and the burning sensation from the Mangekyou Sharingan deep within his brain, and slowly straightened up. His newly awakened eye power flowed coldly in his eyes, clearly taking in Naruto's disheveled state, his charred right hand, and the undisguised pain and exhaustion in his eyes.

"Hahaha...hahaha...hahahahaha!" Sasuke laughed loudly, and after he had laughed enough, he looked at Naruto again: "Naruto, you can't escape this time."

"The Mangekyou Sharingan..." Inside the sealed space, Kurama stared solemnly at the slowly rotating Mangekyou Sharingan patterns in Sasuke's eyes.

"This time, we really have to get serious." Naruto took a deep breath, steam rising from his injured right hand, which then healed in a few breaths. "Let's go, Kurama-nii!"

Naruto's body was once again engulfed in golden flames as he entered Kurama Mode.

The two, standing on opposite sides of the pool, said no more and charged at each other. Their fists and feet clashed with swords. As Naruto attacked, his chakra condensed into claws and attacked Sasuke. Sasuke, whose body was wrapped in black and purple lightning, calmly used the bones of Susanoo to block. For a moment, the two went back and forth, neither able to gain the upper hand.

However, during the fierce battle, Sasuke seized the opportunity, first using his purple lightning to force Naruto back, then closing in and staring intently into Naruto's eyes.

Mangekyou Sharingan Genjutsu, activated!
Caught off guard, Naruto's movements slowed down, and Sasuke seized the opportunity to invade Naruto's sealed space.

After entering the sealed space, Sasuke ignored Naruto, whose pupils already bore the mark of his Mangekyou Sharingan, and instead looked up at the Nine-Tails behind the sealed gate.

"Nine-Tails, it was you who bewitched Naruto, wasn't it! Before these eyes, your schemes come to an end!"

Nine-Tails: ? ? ?
