Flying Thunder God Right to the Face from the Start! The Golden Flash Swore Brotherhood on the Spot!

The air was thick with the stench of gunpowder and blood, made even heavier by the standoff between the two.

Minato Namikaze's azure eyes were fixed on Kamizuki Yu. Those crimson, pinwheel-patterned Sharingan filled him with immense pressure.

A genin had instantly killed a jonin using an unheard-of spatial ninjutsu.

It was beyond his comprehension.

"You're... a Hidden Leaf ninja?" Minato Namikaze broke the silence. Though the other man's forehead protector and attire already revealed his identity, he still needed confirmation.

Kamizuki Yu calmly watched the future Fourth Hokage.

"As you can see." His answer was brief. The power of his Sage Body and the ocular strength of his Eternal Mangekyō gave him complete confidence.

Minato Namikaze sensed no hostility from him, only an unfathomably calm presence.

"That technique just now... was it your bloodline limit?"

Kamizuki Yu neither confirmed nor denied it.

"On the battlefield, any technique that kills the enemy is a good technique."

That answer was no answer at all, but Minato Namikaze did not press further. Everyone had secrets.

"The situation here has stabilized for now. Come back to the command tent with me. Your appearance needs to be reported to Lord Shikaku and the others." Minato Namikaze extended an invitation.

He needed to learn this boy's origins, as well as whether such terrifying power could be controlled.

Kamizuki Yu gave a slight nod.

"Fine."

He also needed a reasonable identity to integrate into this world. Contacting Hidden Leaf's upper ranks was the first step.

Besides, the system's newly refreshed check-in location was inside the command tent.

The two moved one after the other through the scarred battlefield.

Minato Namikaze was extremely fast, yet he deliberately slowed his pace and occasionally observed the boy beside him.

Kamizuki Yu walked steadily, as though the shocking slaughter from moments ago had nothing to do with him.

Before long, a fairly large temporary camp came into view. Security around it was tight, and patrolling Hidden Leaf ninja frequently cast wary glances their way.

The instant he stepped into the camp's guarded perimeter, Kamizuki Yu silently muttered to himself.

"System, check in."

[Ding! Check-in successful at [Land of Fire Border—Konoha Frontline Command Tent]! Congratulations, Host, you have obtained a divine-grade reward: [Flying Thunder God Technique (Perfect Mastery · Includes Technique Formula Improvement Concepts)]!]

A vast and intricate torrent of information flooded into his mind. It contained everything concerning the Flying Thunder God Technique, from its basic principles to its various applications, even several inconceivable methods of improving its formula.

Kamizuki Yu's body paused slightly before returning to normal.

Countless golden formula runes flowed, analyzed, and reconstructed themselves in his mind, eventually becoming instincts he could command perfectly.

If Minato Namikaze's Flying Thunder God was the creation of a genius, then what Kamizuki Yu now possessed was a perfect version optimized to the utmost by the system, built upon the shoulders of giants.

Inside the tent, the atmosphere was solemn.

Before the map, Shikaku Nara frowned deeply, his distinctive moustache twitching slightly. Beside him, Choza Akimichi stood with his arms folded, his expression equally grim.

"Minato, you're back. How did it go?" Shikaku Nara looked up and was slightly surprised to see Kamizuki Yu behind Minato Namikaze.

Minato Namikaze spoke steadily. "The Hidden Rock squad on the western side has been eliminated. This is Kamizuki Yu, a Hidden Leaf genin. He made significant contributions in this battle."

He paused, gathering his words.

"Using an unknown spatial ninjutsu, he killed a Hidden Rock jonin alone, along with at least ten Hidden Rock chunin and genin."

The tent fell silent at once.

Shock appeared on both Shikaku Nara's and Choza Akimichi's faces.

A genin? Killing a jonin alone? With spatial ninjutsu?

It sounded like pure fantasy.

"Minato, are you sure?" Choza Akimichi asked in a muffled voice, his massive frame exuding intense pressure.

"I saw it with my own eyes." Minato Namikaze's tone was certain.

From a corner of the tent, a slender Hyuga ninja with pale, glowing eyes stepped forward.

He was Tokuma Hyuga, an elite jonin from the Hyuga branch family, renowned for his speed and the insight of his Byakugan.

"Captain Minato, you're Genin Kamizuki Yu, right?" Tokuma Hyuga turned to Kamizuki Yu, his tone scrutinizing. "Killing a jonin is certainly impressive. But battlefield conditions are complicated. Sometimes, luck matters too."

The implication in his words was clear: he doubted him.

"I've heard that Lord Kamizuki is quite formidable. Would you allow me to offer you a little 'guidance'? After all, the battlefield is dangerous. The more we understand each other, the safer we'll be."

It was called guidance, but it was really a test.

Shikaku Nara did not stop him. He wanted to see the strength of this "genin" with his own eyes as well.

Kamizuki Yu was long accustomed to such tests.

In his previous life as an office worker, the open and hidden attacks in the workplace had been far less straightforward than this.

A faint curve appeared on his lips.

"Fine."

The instant the words left his mouth, Kamizuki Yu vanished from where he stood.

Tokuma Hyuga had already activated his Byakugan. His vision had no blind spots across three hundred and sixty degrees, yet he failed to catch even an afterimage of his opponent.

A chill suddenly ran up the back of his neck.

Every hair on his body stood on end as he instinctively tried to counterattack.

But a hand holding a kunai had already lightly pressed it against the major artery at the back of his neck.

The icy touch stiffened his body.

At the same time, strange yet refined golden technique formulas silently appeared across the command map in the tent, at the edge of the table, on the tent supports, and even along the rim of the teacup before Shikaku Nara.

Those formulas flashed and vanished in an instant.

"This... this is... the Flying Thunder God Technique?!" Minato Namikaze was the first to cry out.

He saw it clearly. Those distinctive formula marks and that ghostly movement technique were precisely the Flying Thunder God that had made his name!

Yet they were also different.

Kamizuki Yu's formulas were simpler and more concealed than his own. There was almost no chakra fluctuation when they activated, as though they had merged into space itself.

Cold sweat seeped from Tokuma Hyuga's forehead. He could feel that if the kunai in his opponent's hand moved even a fraction farther, he would die on the spot.

The suspicion and shock on Shikaku Nara's and Choza Akimichi's faces had completely turned into awe.

Instantaneous, perfect, and even superior to Minato's Flying Thunder God in certain details!

Was this really a technique a genin could master?

Kamizuki Yu withdrew his kunai and took a step back, as if he had merely done something trivial.

"You let me win."

Tokuma Hyuga's face alternated between green and white. He opened his mouth, but could not say a single word.

The speed he had always taken pride in was child's play before his opponent.

"Lord Kamizuki, your Flying Thunder God..." Minato Namikaze stepped forward, his azure eyes filled with delight and curiosity. "Your formula seems different from mine. It's more... refined!"

From Kamizuki Yu's Flying Thunder God, he saw the possibility of improving his own technique formula.

Kamizuki Yu replied calmly, "I gained a little insight on the battlefield and figured it out myself."

No one believed that explanation, but no one pursued it either.

Geniuses always had their peculiarities.

Minato Namikaze, however, seemed to have found a kindred spirit. He eagerly pulled Kamizuki Yu into a discussion of the Flying Thunder God Technique's various details and applications.

Kamizuki Yu was happy to exchange ideas with the future Hokage as well. His perfectly mastered knowledge allowed him to handle the conversation with ease, and he occasionally offered unique insights that left Minato Namikaze enlightened and exclaiming in delight.

Shikaku Nara watched the scene before him, his thoughts racing.

A boy who possessed a perfect Sage Body—though they did not know exactly what it was, only that his recovery ability was astonishing—along with strange spatial ocular techniques and such an exquisite Flying Thunder God Technique.

He could no longer be described as merely a genius.

He was a trump card capable of changing the course of the war!

"Ahem." Shikaku Nara gave a light cough, interrupting the spirited discussion between the two users of spatial ninjutsu.

"Kamizuki Yu, what are your thoughts on the current battle situation at Kikyo Mountain?" he asked directly, wanting to see the boy's strategic vision.

Kamizuki Yu glanced at the map.

His knowledge of the Naruto storyline from his previous life meant he knew the course of this campaign inside and out.

"Hidden Rock's current offensive is fierce, but their supply line has been stretched too far. In particular, Bird Slope Passage to the northwest is a dangerous terrain, easy to defend and difficult to attack, yet it is a key point in their logistics."

He extended a finger and pointed to an inconspicuous spot on the map.

"If an elite squad can launch a lightning assault there and cut off their food, supplies, and weapons, the Hidden Rock army will collapse into chaos without even needing a battle."

Shikaku Nara's pupils suddenly contracted.

He and the command staff had considered this plan as well, but it was extremely risky and required absolute control over timing and troop deployment.

Yet Kamizuki Yu had pointed directly at the heart of the matter.

"It is an excellent plan, but how can we ensure that the raiding force breaks through Hidden Rock's defenses and returns safely?" Shikaku Nara pressed.

Kamizuki Yu looked at Minato Namikaze.

"With Captain Minato, my Flying Thunder God, and an elite ANBU unit, we can complete the mission before Hidden Rock has time to react."

His tone was calm, yet it carried immense confidence.

At those words, a sharp glint flashed through Minato Namikaze's eyes.

"I understand!"

Shikaku Nara looked at the boy before him. This Kamizuki Yu, who called himself a genin, was worth far more than a mere combat unit.

"I will give your battle plan serious consideration."

He turned to Kamizuki Yu, his attitude now completely different.

"From this moment onward, you will temporarily be assigned to Minato's direct squad and await orders."
