Thunder Breathing × Composite Chakra

Is it Illusion Jutsu?

No, there was no Chakra fluctuation... Shisui stared blankly at the faded world before him, the three scarlet tomoe in his blood-red eyes slowly swirling, without sensing any trace of "Illusion Jutsu".

But if it wasn't "Illusion Jutsu," how did Nii-san manage to do it?

Shisui was watching, and Itachi was watching too. The [Transparent Domain] transformed into a delicate gray, instantly enveloping the two small figures... In just a moment, it captured their flesh, bones, movements, and breaths completely, as if they were... invisible people, and of course, it also included those standing to the side...

Sakumo Hatake!

The man stared at the two Great Sun slowly turning in Roy's eyes, and felt a rare sense of restraint.

He hadn't felt this way in a long time; he couldn't remember when it started.

But Sakumo Hatake knew that, given his reputation and strength, there were very few people who could give him that feeling nowadays.

The Kage of each major ninja village counts as one... the Tailed Beast counts as one... other genius Ninja like Namikaze Minato count as half... and the rest, it seems, are just this half-grown child in front of me who is not even six years old!

Six years old... He's two years younger than Kakashi!

A glint of light flashed in Sakumo Hatake's eyes. Stepping on the exquisite gray, he sensed his every move being peeled back, revealing threads of Lines of Flaw that connected to Roy. He said incredulously, "Just a few days ago I was talking to your father about taking you as my apprentice. Now it seems... I was naive."

"I never imagined you'd already found your own unique Sword Path!"

"The Sword Path..." Shisui sat to the side, lost in thought.

Itachi was younger than him and didn't quite understand, but that didn't stop him from gleaning a word from Sakumo Hatake's words and his brother's words: "Sword Eye"!

Sword Eye...

As the name suggests, is it... the eye of the sword?

In other words... "From now on, whether it's a sword or Kunai... there won't be any way to escape Nii-san's Sword Eye?"

The Sun-Earring Boy's mind wandered, and he unconsciously gripped the knife in his hand.

"Uncle White Fang, you flatter me," Roy said calmly, holding his sword level and gently Eclipse the Great Sun's radiant heat. "These are just trivial skills, far from ' the Sword Path '..."

"A mere trick?" Sakumo Hatake's lips twitched almost imperceptibly, and he smiled with narrowed eyes, "You've seen through every move I make, and you call that a mere trick?"

The unknown is the most terrifying; conversely, the known is not so scary at all. As long as we find a way to deal with it, we can easily solve the problem.

However, White Fang of the Leaf almost never needs a second strike to kill; it's often a single, "unknown" strike that easily ends the opponent's life.

Now... Sakumo Hatake looked at his hands, feet, and joints, all of which were connected by "Lines of Flaw." Any movement would be sensed by Roy, who would anticipate and counterattack...

His expression turned serious, and with a loud "boom," he unleashed an unprecedented aura!

He channeled all his Chakra into White Fang, and for a moment... blinding lightning flashed, forcing Shisui...

Itachi had to raise his little hand to cover his eyes... The two children felt as if they had been grabbed by a giant hand and thrown into a sea of lightning; their bodies went numb, they lost consciousness, and they struggled to see through their fingers...

All they could see, with great difficulty, was that their White Fang uncle seemed to have raised his knife!

"Sizzle~" The electric arc exploded into a ball shape!

With Sakumo Hatake's White Fang in hand, it was as if he were holding lightning. In an instant... it gave Roy the illusion that he was seeing Kakashi wielding Lightning Blade in the original manga!

One is a "ninjutsu," and the other is a pure "Lightning Release" Amplification... they are not comparable!

"Roy, you're right. The Sword Path is too distant, too ethereal..." The man's white hair stood on end. He slowly flipped his wrist, revealing his White Fang. The tip of his blade crackled with lightning, pointing directly at Roy's heart. His feet were spread apart in a lunge stance, and with another step... he vanished in an instant... like lightning...

The knife was already piercing Roy's body when his unfinished words finally reached him from afar!

He said, "I don't really understand either, but I only need to know one thing, as long as..."

"I'm fast enough!"

That's enough!

Really!

Fast enough!

With the Lightning Release, he transforms into a movie character...

Roy had anticipated and imprinted Sakumo Hatake's sudden thrust the moment he made his move, but... his body's instinctive reaction made him a little slow, and he felt a chill on his chest as a piece of his clothing was torn open.

"Sizzle~" A flash of lightning, and Sakumo Hatake reappeared, the man holding White Fang, twirling a piece of his clothing, turning back to look at him. "You dodged quickly."

It was fast... relying on the [Eyes of Truth advance perception... but, "It still couldn't dodge it..."

After his previous attempt failed, Roy gripped the Eclipse and gave it a gentle shake, shattering the tiny arcs of electricity that were trying to penetrate his body. He then looked up at Sakumo Hatake, frowning as he fell into deep thought.

[Hint: "Swordsmanship" +10... First Encounter with [Lightning Release]... Nen Ability Nature "[Lightning]" has been activated...]

Lightning... "Thunder Breathing..." The "Sea of Cognition" surged with towering waves, washing over the "Gate of Demon Slayer."

The doorway, adorned with a "Demon" ornament, trembled and opened a crack, revealing an old face with white hair and beard.

Roy carefully sensed the Thunder -infused strike of Sakumo Hatake, his consciousness immersed in the panel's notifications. In a daze, he entered the Gate of Demon Slayer, just like when he learned "Water Breathing" from Urokodaki Sakonji ago. This ethereal consciousness transformed into an outsider, quietly watching the old man named Kuwajima Jigoro, holding a stick, tirelessly instructing his two disciples. Before his eyes were nothing but "speed" and "lightning"!

"Thunder Breathing, First Form: Thunderclap and Flash..."

"Second Form: Rice Spirit...

"The 'Ginseng-like Formation' - Gathering Mosquitoes Like Thunder..."

"Fourth Form: Distant Thunder..."

"Type 5... Sixth Form..."

Before I knew it, I was completely absorbed...

"Hmm?" In the [Transparent World], the Sun-Earring Boy froze, gripping the knife in his hand like a stubborn rock, lifeless and unconscious.

At this moment, the world, which had faded, regained its former colors; the surrounding green trees, blue stones, birds, white clouds, and gentle breeze returned...

Shisui and Itachi felt a blur before their eyes, and when they looked at each other again, it was as if they had fallen out of the world and were back in the Southern Forest. Not far away... was the thick tree that their Nii-san had cleaved in two with his flying sword.

"This...

Nii-san...

"Is this an admission... of defeat?"

Shisui and Itachi exchanged glances, staring at Roy who remained silent with his eyes closed... but Itachi, with his sharper eyes and more perceptive mind, suddenly noticed...

Sakumo Hatake did not lower his sword!

The man frowned as he watched Roy frown, then calmly removed the piece of clothing that was being held by the tip of the knife. His flowing white hair swayed in the wind, crackling with arcs of electricity... He waited for Roy to open his eyes again, then gently released his grip...

The hem of her dress fluttered in the breeze, swirling as it flew to the Sun-Earring Boy, where he caught it in his hand with a single swift motion.

The Sun-Earring Boy bowed respectfully at the opportune moment. "Thank you, Uncle White Fang, for returning my torn clothes. If my mother sees that my clothes are torn, she might scold me."

"Heh heh... Mikoto isn't that kind of person, but... you!" White Fang of the Leaf stared intently at the Sun-Earring Boy: "You've really given me a big surprise!"

"Surprise... is this what you mean?" Roy gently stroked the Eclipse, the flames dissipated, but a bolt of lightning suddenly appeared in everyone's sight, like a lightning serpent, winding and crawling along the blade, instantly wrapping Asauchi into a... lightning blade!

"Sizzle~" Roy pointed his knife diagonally, and a flash of lightning pierced through the tip of the blade and into the ground, creating a deep crater. The crater was small, far less terrifying than the slash that split the tree, but... it was lightning... which meant...

"Nii-san has also mastered lightning Chakra!"

Shisui was stunned... He had been with Roy since he was a child and had only ever seen "fire," this was the first time he had ever seen "lightning"!

The Sun-Earring Boy tilted his head and asked Itachi, "Do you know?"

Itachi stared blankly at the Eclipse, which was crackling with lightning, in Roy's hand. After a long silence, he slowly shook his head. "This is the first time I've ever seen one like this either."

Shisui:

Silence.

"Whoosh~" A gust of wind blew by, stirring up some sand and dust.

Beside the broken tree, two children sat cross-legged watching, while Roy Sakumo Hatake stood on either side, their hands simultaneously unleashing bolts of lightning...

At one point, he charged at the other again!

However, this time, it's thunder against thunder!

Roy opened all the Aura Nodes in his body, transforming all his "thoughts" into "lightning." He became like an electric snake, flicking his tongue and striking out... This strike... a draw slash!

It is indeed "Thunder Breathing - First Form - Thunderclap and Flash!"

"Clang!" The weapons clashed, the Eclipse struck White Fang, and lightning erupted from the two of them!

Sakumo Hatake savored Roy's every move, from his footwork to his stance, and then to the swift draw of his sword, aimed directly at Roy's throat... It was a wondrous swordsmanship he had never experienced before!

The man was startled, lowering his forearm to knock Roy back. He then swung his sword in a backhand strike towards Roy's chest. Roy ducked, drew his sword again, and with a single upward slash, instantly struck five Thunderbolt —it was... "Thunder Breathing Second Form: Rice Spirit!"

Then... Third Form... Fourth Form... Type 5... Sixth Form...

Flashes of electricity... the sounds of blades striking each other incessantly... and the notification sounds from the control panel echoed continuously.

Taking advantage of the opening when he activated [Lightning Release], Roy quickly mastered [Thunder Breathing] using "Sun Breathing," constantly clashing with Sakumo Hatake, and soon...

The [Lightning Nen Ability Nen Ability Nature Transformation " category, is rapidly increasing.

"Too fast... too fast... completely invisible..." In his crimson eyes, the three tomoe swirled so fast they were practically smoking... Shisui stared intently at the two combatants, yet still couldn't catch a glimpse of Roy and Sakumo Hatake!

The two were like lightning, flashing and colliding in a blur, making it impossible to discern any sword-drawing movements or stances. As for... Itachi...

The Sun-Earring Boy put his hands behind his head, lay down on the spot, and simply stopped looking. He waited for Shisui to curiously nudge him, and heard him say, "Rest, after all... we still have extra practice later."

Shisui's face fell. Remembering that Roy had just punished him with ten thousand cuts not long ago, he simply lay down next to Itachi and dispelled his Sharingan.

"Clang, clang, clang..."

The sounds of clashing weapons grew louder and louder.

At a certain moment, a thunderous roar erupted!

"Bite"

Eclipse against White Fang, a blade against a blade!

Roy Sakumo Hatake stood in their imaginations, each pointing at the other, one with black hair and the other with white hair, standing silently... After a moment, they looked at each other and smiled, then sheathed their swords.

"Your Ray is even better than I imagined," the man said.

"Your knife is even faster than I imagined," the Sun-Earring Boy said.

Then, a gentle breeze came.

Two figures, one large and one small, each spread their arms out, mimicking Itachi and Shisui, lying on the ground in a starfish shape, facing the blue sky, watching the bright Great Sun and drifting white clouds. They stopped fighting for a rare moment and enjoyed the peace after the battle.

[Hint: "Nen Ability Nature Transformation" +10...]

[Current [Thunder]: lv2 (142/1000)]

The notification sound from the panel has faded away...

Perhaps a drop of dew hadn't yet evaporated in the sunlight, it dripped down from a green leaf overhead and landed Roy's eyebrows. The Sun-Earring Boy felt the coolness and tilted his head, saying, "Thank you."

Unexpectedly, at the same moment, Sakumo Hatake turned his head and looked over, also saying, "Thank you."

Both of them were taken aback for a moment, then smiled and asked each other, "What are you thanking me for?"

"Thank you for your guidance," the Sun-Earring Boy said.

"Thank you for letting me hit so hard for so long," the man said.

"That's because Uncle White Fang is too strong," the Sun-Earring Boy added.

"That's also because you're not weak either," the man added.

Sakumo Hatake rolled over, turning to face Roy, and looked at the Sun-Earring Boy seriously, saying, "Child, don't easily pass on your swordsmanship skills to others."

"Why?" Roy also rolled over, facing Sakumo Hatake, and said, "Can't I give it to you, Uncle?"

"For me?" Sakumo Hatake was taken aback.

"Yes."

[Hint: Detecting one "Believer"...]

["Believer" Sakumo Hatake's loyalty increases by 5 due to his high regard for his host...]

Roy rolled over and got up from the ground, dusted himself off, and solemnly bowed to Sakumo Hatake, saying, "Uncle White Fang is no ordinary person, and... what you taught me today is far more than I could have given you."

"But I didn't teach you anything." Sakumo Hatake couldn't lie down any longer.

He stood up and patted Roy on the shoulder. "It's all your own stuff."

Roy didn't explain. With a thought, he connected with the "Thunder Breathing" to condense a "Nen Flow," which shot towards a point on Sakumo Hatake's chest... Information exploded, splitting into several streams that flowed into the man's mind, and then—

The man froze, then regained his senses, repeatedly pondering the sword technique called "Thunder Breathing" that had appeared in his mind. He looked at Roy with a complicated expression, momentarily at a loss for words.

In the end, he could only pat Roy on the shoulder, say goodbye, and leave.

"Tap... tap..." The footsteps faded into the distance.

The notification sound on the panel arrived late, [Notification: "Believer" Sakumo Hatake is grateful to the host for imparting the "Thunder Breathing" technique, loyalty +5.]

..]

[Current Loyalty: Absolutely loyal, you can rely on someone's back...]

Roy listened silently, watching until Sakumo Hatake was out of sight, then suddenly asked, "Have you seen enough?"

Startled Shisui and Itachi, he coldly shot a glare towards a corner of the sky.

In the Hokage Building, Sarutobi Hiruzen back in his chair, dispelling the <Clairvoyance Jutsu> with one hand, and silently moved the Crystal Ball aside...
