Traveling through Naruto, I am Uchiha Obito?

Carrying the scroll containing the Uzumaki clan's sealing techniques, the Rubik's Cube left the Hokage Building.

The sun shone brightly on the bustling streets, and the villagers wore peaceful smiles. The sounds of children chasing and playing were clear and melodious. He looked down at the gift from three generations in his hand, his fingertips tracing the slightly worn leather edge of the scroll, a complex smile curving his lips.

He recalled what the Third Hokage had said to him in the Hokage's office.

Rubik's Cube was well aware of the dark side of power and the filth within its vortex. Long before coming to Konoha, he had prepared himself to harbor the utmost malice towards these high-ranking officials.

To his surprise, the Third Hokage truly loved Konoha from the bottom of his heart and genuinely cared for him, his grand-disciple. Even though he was indeed a very shrewd and experienced politician, this love could not be faked.

This spirit of protection is the foundation that supports Konoha, and it is also an important reason why the Will of Fire can be recognized by so many people and passed down from generation to generation.

The Third Hokage's sincerity and kindness were one of the reasons he chose to help them; of course, the generous reward was also key.

After carefully putting the scroll away, Rubik's Cube strolled towards a relatively secluded training ground on the outskirts of Konoha Village. Just as he stepped to the edge of the field, a burst of energetic shouts and the sharp sounds of fists and feet cutting through the air reached his ears.

"Drink up! Lee! Faster! For the Chunin Exams, give it your all, Lee! The sweat of your youth will never betray you!"

A man with thick eyebrows, big eyes, and a watermelon-shaped hairstyle, wearing a signature green bodysuit, is passionately instructing a boy with a kappa-like hairstyle, also wearing a green bodysuit, on high-speed physical training. Beside them, a boy with white eyes and a Konoha headband and a cute girl with a bun hairstyle, both with a cool demeanor, are quietly watching the training.

It was none other than Konoha's Blue Beast—Might Guy, and his subordinates Rock Lee, Neji, and Tenten.

Kai keenly sensed someone approaching, stopped instructing Xiao Li, and his bright eyes, beneath his thick eyebrows, instantly locked onto the Rubik's Cube.

He tilted his head, a puzzled expression on his face, as if he was trying hard to recall but couldn't figure it out, and scratched his chin with his thick fingers.

"Huh??? This guy... wait! He looks so familiar! I'm sure I've seen him somewhere before! This... this... um? Where?" Kai slapped his forehead hard, as if trying to find the answer from inside.

"This familiar feeling! Encounters in youth are always full of mysteries!"

Neji Hyuga, standing to the side, had already subtly activated his Byakugan, calmly observing the Rubik's Cube for a moment. Hearing Kai's confusion, his cool voice rang out, carrying a barely perceptible hint of a reminder:

"Teacher Kai, he should be the disciple of the legendary Jiraiya. Not long ago, he defeated Mr. Kakashi in a head-on battle at the training ground."

"What?!?!"

Kai's eyes widened instantly, his mouth gaping open wide enough to fit an egg. His earlier confusion was instantly replaced by a volcanic eruption of enthusiasm; he seemed to be set ablaze!

"Jiraiya-sama's disciple?! And he even defeated Kakashi?!"

Kai's voice suddenly rose eight octaves. He rushed to the Rubik's Cube in one stride, so fast that he almost left a blur. He excitedly gripped the Rubik's Cube's shoulders with both hands, his eyes burning with fierce fighting spirit, and his thick eyebrows twitching violently.

"This is the destined showdown of youth! Kakashi is my eternal rival! The man who can defeat him is definitely a strong opponent worthy of my Might Guy's burning passion to challenge!!"

He was trembling with excitement, and said in a loud voice:

"Mr. Rubik's Cube! Please accept my sincere challenge! Let's have a magnificent duel where we stake our manly dignity and youth!!"

The Rubik's Cube was slightly taken aback by the sudden enthusiasm, then, feeling the iron clamp-like force on his shoulder and seeing Matt Kai's excited expression, a smile of excitement slowly crept onto his lips.

Sure enough, compared to those cunning old bastards who are all scheming, I still prefer pure and kind people like Matt Kai.

Handsome guy, you've piqued my interest.

"The Eight Gates...?" A glint of eager anticipation flashed in his eyes. He gently pulled his hands away from Kai's tight grip, met the other's expectant and fighting gaze, and nodded, his smile carrying a hint of joy, yet tinged with seriousness:

"Sure, I'd like to get some exercise too. Please guide me, hot-blooded watermelon head."

"Ooo ...

"This is what youth is all about! Mr. Rubik's Cube! Let's burn brightly! Lee! Neji! Tenten! Watch closely, this is the clash of the strong!!" He excitedly waved his fist at his disciples.

The atmosphere on the training field was instantly ignited.

……

In the center of the training field, two figures collided violently at a speed imperceptible to the naked eye! The explosive sounds of their punches and kicks hitting each other were like dense drumbeats, making the air buzz.

At this moment, the Rubik's Cube truly felt the terror of the Blue Beast of Konoha! Might Guy's taijutsu was pure and direct, with every punch and kick containing immense power. Even more terrifying was his incredible speed and relentless, raging onslaught!

Kai seemed to transform into a relentless fighting machine, pushing the most basic straight punches, side kicks, and elbow strikes to their limits, creating an impenetrable storm of attacks.

"He's really strong! No wonder he almost ended the series with a single kick!"

Rubik's Cube felt a chill run down his spine. His physical skills were already quite formidable, but he felt significant pressure in the face of Kai's pure physical prowess, honed through countless trials and developed to the extreme!

Each block sent shivers of tingling numbness through his arm; each dodge was a close call. Kai's attacks were like a persistent, insidious attack, giving him no chance to catch his breath or form hand seals!

"Prolonged defense will inevitably lead to defeat!" Rubik's Cube's eyes sharpened. He took a heavy sweeping kick from Kai, using the momentum to slide backward rapidly, instantly creating a distance of more than ten meters. Taking advantage of this precious gap, his hands had already become afterimages!

"Fire Release·Dragon Fire Technique!"

A surge of intense chakra coalesced in his throat, instantly forming a ferocious, roaring fire dragon that lunged at the pursuing Guy! The scorching heat made Lee and Neji, who were watching from afar, feel their skin burning.

"Guy-sensei!" Lee exclaimed in shock, his face filled with worry. Such a powerful fire jutsu at such close range—even Guy-sensei would have a hard time escaping unscathed, right?

"Hmph, you stupid Lee, watch closely!" Neji's Byakugan was fixed on the battlefield, his cold face showing no emotion, but rather a hint of disdain for Lee's overreaction. "How could Guy-sensei be trapped by such an attack?"

As if to prove Neji's words, facing the roaring fire dragon, Kai not only did not back down, but the fighting spirit burning in his eyes became even more intense!

"Konoha Whirlwind - Modified!"

With a roar, Kai's figure blurred instantly! He didn't dodge in a straight line, but instead spun rapidly in place! His legs transformed into two raging green hurricanes! The astonishing speed stirred up the surrounding air, forming a visible, violent circular whirlwind! This whirlwind wasn't for defense, but rather, with his exquisite martial arts skills, he transformed it into a powerful pulling and tearing force!

boom--!

The fiery dragon crashed violently into the whirlwind of physical attacks created by Kai. The raging whirlwind, like a giant meat grinder, tore apart, dispersed, and engulfed the scorching dragonfire! The flames, caught in the whirlwind, transformed into countless tiny sparks, like tamed beasts, spinning rapidly around Kai, forming a spectacular yet dangerous fire tornado! And Kai, at the very center of this fiery whirlwind, remained completely unharmed!

"Using pure taijutsu to manipulate airflow, creating a whirlwind barrier powerful enough to distort and disperse ninjutsu... what amazing skill and control of power!"

Rubik's Cube's pupils contracted slightly, and his evaluation of Kai rose even higher. This was by no means brute force, but a qualitative change that came from mastering physical skills to the extreme!

"Lord Rubik's Cube! Your strength is indeed extraordinary! Be careful of my next attack!"

Kai's voice, filled with excitement and approval, came through the whirlwind of flames. The green energy around him suddenly surged, erupting like tangible steam! The veins beneath his skin were clearly visible, and the powerful chakra fluctuations caused the entire training ground to tremble slightly!

"Eight Gates Formation, Fourth Gate, Injury Gate! Open!!"

Boom! A terrifying aura, far surpassing anything before, surged into the sky! The ground beneath Kai's feet cracked inch by inch! At this moment, he was like a prehistoric beast unleashed from its shackles!

"Tsk, they're getting serious!" Rubik's Cube's eyes were serious, but a hint of excitement curled at the corner of his mouth. Facing Guy who had opened the Fourth Gate, ordinary ninjutsu and taijutsu alone were no longer enough!

"Earth Release·Earth Spear!"

Rubik's Cube formed hand seals and used a signature enhanced ninjutsu of an immortal ninja from the Akatsuki organization.

"Wind Release: Armor!"

With a low shout, Rubik's Cube unleashed a unique ninjutsu technique he had developed, combining Wind Release chakra nature transformation! The raging wind-style chakra was rapidly compressed and spun by his precise chakra manipulation skills, adhering tightly to his body like flowing armor! A blue aura swirled around him, emitting a sharp hiss!

Wind Release Chakra Mode! Greatly increases speed while granting stronger cutting power to limb attacks!

"Sharingan awakened!"

Facing an opponent of this caliber, the Rubik's Cube felt a long-lost excitement.

"Come!" Rubik's Cube roared, its figure wreathed in cyan gusts of wind, and took the initiative to meet Kai, who was radiating terrifying green energy!

Bang! Boom! Crack!

The clash between the two escalated instantly! With the opening of the Injury Gate, Kai's speed and power reached a whole new level, and every attack was accompanied by a shrill whistling sound that tore through the air.

The Rubik's Cube relied on the sturdy defense of its earth spear to withstand the impact, while simultaneously using the speed brought by its Wind Release Chakra Mode and the wind blades wrapped around its skin to launch a counterattack! Fragments of the training ground ground flew continuously at the point of impact, and the cyan wind blades and green energy blasts collided wildly.

The center of the battlefield was like a battlefield where countless bombs had exploded! Smoke and blasts of air billowed! Xiao Li watched with his blood boiling and his eyes shining.

Neji's Byakugan was fixed on the two figures moving at high speed and colliding fiercely, and fine beads of sweat even appeared on his forehead—he couldn't even see them clearly in a battle of this level.

"Awesome! The Rubik's Cube!!" Kai exclaimed enthusiastically during the intense exchange.

"Your physical skills and techniques are making every cell in my body scream! This feeling of burning with youthful energy!"

"Fifth Gate - Closed Gate! Open it for me!!!"

Guy's roar was like thunder! An even more violent and profound blue chakra steam erupted, blasting a shallow crater in the ground beneath his feet! With the Gate of Death activated, Guy's speed once again soared to an unbelievable level!

"Not good!" Alarm bells rang in Rubik's Cube's mind! The power of the Gate of Death far surpassed that of the Gate of Injury! Kai's figure almost transformed into a streak of blue light!

boom!

With a muffled thud, Rubik's Cube took a solid kick to the chest, which was reinforced by the Earth Spear! Even with the dual defense of the Earth Spear and Wind Release chakra, an unimaginable force still penetrated his body! Rubik's Cube was sent flying backward like a cannonball, as if hit by a battering ram, crashing into a large tree at the edge of the training ground and snapping it in half!

Smoke and dust filled the air.

Rubik's Cube stood up from the shattered tree trunk, wiped away a trace of blood from the corner of his mouth, and looked at Might Guy in the distance, who was exuding a terrifying aura. His eyes burned not only with fighting spirit, but also with a touch of solemnity and genuine excitement!

"The Eight Gates Formation... truly insidious... but that's precisely why I'm worth taking down!"

Chapter 26 Battle of the Six Gates

The dull pain in his chest continued to spread, but the fighting spirit in Rubik's Cube's eyes burned even brighter. He looked at Might Guy in the distance, whose imposing aura was like a rainbow and whose body was shrouded in violent steam, and grinned, revealing a blood-tinged, excited smile.

"As expected of the number one martial arts master certified by Wang Wenwang, he's really amazing. This enthusiastic atmosphere is getting me fired up too."

Rubik's Cube clasped his hands together abruptly, and the nature of his chakra underwent a dramatic change.

"Lava Release: Chakra Mode!"

With a low shout, dark red, viscous lava radiating terrifying heat seemed to come alive, rapidly seeping out, spreading, and solidifying from his body! In an instant, a ferocious, heavy lava armor flowing with dark red luster enveloped his entire body. Lava slowly flowed on the surface of the armor, emitting astonishing heat waves that scorched and distorted the surrounding air.

This was the spoils he obtained from Rōshi, the Four-Tails Jinchūriki, when he and Jiraiya traveled through the ninja world, and it was also one of the sources of inspiration for his development of ninjutsu and taijutsu!

"It's not over yet!" The Rubik's Cube continued its movements, pressing its hands against the ground once more!

"Earth Release: Granite Technique!"

Rumble! The ground trembled violently, and massive, hard granite boulders gleaming with a mineral sheen rose from the earth, encircling the Rubik's Cube's lava armor and forming a second, even thicker and more solid rock barrier! At this moment, the Rubik's Cube resembled a war fortress clad in double armor of lava and granite!

"Oh?! The bloodline limit of Lava Release?!" A strong fighting spirit burst forth in Kai's eyes, but a sense of vigilance flashed through his mind in an instant.

He could clearly feel the terrifying heat and astonishing defensive power contained within the lava armor! Close combat was his forte, but facing this flowing armor radiating destructive heat, every punch and kick carried immense risk.

—Not only will your power be absorbed or deflected, but you may also be instantly burned by the scorching lava!

'Troublesome!' Kai thought to himself.

Ordinary physical attacks would likely be much less effective against it, and might even injure the attacker! We need to use greater speed, more power, or… change our attack method!

"Youth must be a continuous burning flame!"

Kai laughed loudly, and the chakra steam around him churned violently as if boiling! He made a decision in an instant! Close combat was too risky; he had to use a stronger explosive force to tear through the defenses!

"Ohhhhhhh—!! Lord Rubik's Cube! I have truly received your enthusiasm! This power that can ignite the soul! It deserves my response with an even more fervent youth!!"

"Sixth Gate - View Gate! Open—!!!"

boom--! ! ! !

A terrifying torrent of chakra, far surpassing the power of the Gate of View and as powerful as a tangible tsunami, erupted from Guy's body! The ground beneath his feet instantly collapsed into a massive crater! Deep green steam almost completely engulfed his figure! The power brought by opening the Gate of View was devastating!

"Morning! Peacock—!!!"

Kai's roar shook the heavens and earth! His fists became afterimages beyond the limits of vision! Extremely fast! Extremely numerous!

Bang bang bang bang bang bang-! ! ! !

Countless visible fire shockwaves, generated by the pure, high-speed friction of fists against the air, erupted out like a peacock spreading its tail feathers—both magnificent and deadly! Their target was the Rubik's Cube, clad in lava armor!

Kai chose to use the power of the View Gate to unleash the ultimate technique of long-range area attack, attempting to forcefully blast open or even destroy that troublesome lava defense with sheer numbers and impact!

"Long-range air combat? Just what I want!"

Faced with this overwhelming offensive, Rubik's Cube was excited. In this ninja world where everyone was a cunning old fox, such a full-force battle was extremely rare.

"Lava Release: Meteor Volcano Modified!"

Dozens of condensed lava fireballs, each the size of a fist and radiating a blinding red light, instantly coalesced! These lava fireballs did not shoot straight at the attacker, but rather followed extremely tricky and unpredictable arcs, like a dense meteor shower, carrying incinerating temperatures, to meet the oncoming attack head-on!

boom! boom! boom! boom! boom! boom!

The deafening explosions continued unabated! A blinding sun seemed to rise in the center of the training field! Flame air bombs and dark red lava fireballs collided wildly in the air, exploding into a dazzling yet dangerous rain of fire and shockwaves! The entire training field was as if it had been baptized by a storm and flames!

Surprisingly, Xiao Li and his companion, who were watching from the sidelines, were not affected at all. The two of them had very skillfully controlled the scope of the battle's impact.

Amidst the raging fire and billowing smoke that obscured visibility, Cain briefly hovered in the air before landing after releasing the Morning Peacock.

The Rubik's Cube on the ground curled into a triumphant smile. His hands, already concealed by the dust, had completed the final hand seal!

"Earth Escape·Yellow Spring Marsh!"

puff--!

The solid ground beneath Kai's landing point instantly softened and liquefied, transforming into a small but bottomless swamp!
