The Fastest in the Ninja World

As the low shout of "Kou!" rang out, a crimson barrier instantly rose up from around Kou!

That barrier wasn't made of pure Chakra, but rather an absolute defense constructed from countless crimson Chakra of fire-attribute nature transformation!

The menacing black thunder leopard crashed heavily into the barrier wall. The moment it touched the crimson barrier wall, it was as if it had been thrown into a furnace, and was burned to ashes in a matter of breaths!

The Fourth Raikage looked at the scene before him with obvious surprise in his eyes.

He forcefully twisted his waist in mid-air, deflecting the heavy battle axe kick that was originally aimed at him, causing it to slam heavily onto the ground on one side of the barrier.

The earth trembled violently under the blow, and countless cracks spread wildly in all directions. The few fragments of stone that were stirred up were silently burned to ashes the moment they touched the crimson barrier.

The Fourth Raikage landed at the edge of the deep crater he had created with his kick, his expression suddenly turning serious as he looked at the fiery barrier that completely separated him from Kokoro.

Knock sensed the Fourth Raikage standing solemnly at the edge of the pit outside the barrier, rapidly Hand Seals and whispering:

"Expand!"

As he finished speaking, the crimson barrier that had been firmly protecting him at the center suddenly expanded in all directions!

"Lord Raikage, danger!!"

As Darui stared at the suddenly expanding crimson barrier, his usually languid face instantly changed color.

Almost instinctively, he shouted urgently to the Fourth Raikage, who was closest to the barrier.

Ai's gaze sharpened as he heard the urgent shout from his subordinate behind him.

Without lingering in the fight, lightning crackled beneath his feet, and he transformed into a fierce arc of lightning, breaking free from the expanding barrier and landing steadily in front of his two subordinates.

The Fourth Raikage stood in front of his two subordinates, his gaze fixed solemnly on the blazing fire barrier.

"Hey, is this for real?"

Darui looked at the barrier ahead, still flickering with crimson flames, and scratched his head, feeling utterly perplexed.

"To be able to use Barrier Ninjutsu of this level all by himself, when did such an amazing person appear in the Ninja World?"

He turned his head to look at his serious-looking companion beside him:

"Hey, hope, do you know anything about this barrier?"

hope looked solemnly at the crimson barrier wall ahead, and shook his head heavily.

No, I don't recognize this Barrier Ninjutsu.

If I had to pinpoint a similarity, it seems to share some structural similarities with Konoha's Four Violet Flames Formation, yet also appears to have some differences...

A deep thought flashed in his eyes, and he subconsciously turned to the burly figure beside him who was silently gazing at the barrier:

"Lord Raikage, what exactly is that...?"

"Uchiha Flame Formation."

Ai stared intently ahead and answered in a deep voice.

He crossed his arms, his rugged eyes filled with undisguised astonishment and bewilderment:

"A top-tier defensive barrier developed by the Uchiha Clan during the Warring States period."

But this Barrier Ninjutsu should have been lost long ago.

Where did this brat learn this technique? Could it be that the Uchiha Clan has actually preserved the complete lineage of this technique...?

The Fourth Raikage spoke in a low voice, his eyes showing even more doubt:

"Furthermore, according to records of this technique passed down from the Warring States period, the Uchiha Flame Formation should not be able to be expanded upon."

"Could it be that this kid... improved upon this technique?"

"Uchiha?"

Darui blinked in surprise, then turned his gaze back to the slowly dissipating barrier, and said in confusion:

"Wasn't it Sannin, one of the Orochimaru, who broke into the Cloud Thunder Mountain Range?"

This guy... isn't he one of Orochimaru's subordinates?

Orochimaru? He doesn't even deserve it!

The Fourth Raikage scoffed disdainfully, then looked at the slowly dissipating flame barrier, fixing his gaze on the black-haired youth who had revealed himself.

"This man is not someone like Orochimaru can handle."

As the Uchiha Flame Formation slowly dissipated, Kotori's tall and slender figure reappeared.

The hem of his Black Cloak with Red Clouds was still swaying slightly in the mountain breeze, and his right hand was still gripping the Inazuma that was still crackling with lightning.

Kou faced the direction of the Fourth Raikage and the other two, and slowly opened his eyes, which had been tightly closed since the beginning.

Those Three Tomoe Sharingan coldly scrutinized the two Cloud Village Kumogakure who had betrayed their martial ethics and ambushed him.

Darui, the right-hand man of the Fourth Raikage and an elite Kumogakure Jonin Kumogakure who possesses the Storm Release Kekkei Genkai.

Xi, the left-hand man of the Fourth Raikage and Raikage's advisor, is an all-around ninja proficient in sensory perception, Genjutsu, and Medical Ninjutsu.

Darui stared at Ko's eyes, which gleamed with a scarlet light, and for a moment, those languid gazes froze.

"That's... the Sharingan? Is he a member of the Uchiha Clan?!"

hope scrutinized the handsome, black-haired young man before him, a thoughtful glint in his eyes:

"According to the intelligence we received earlier, the Uchiha Clan should have been wiped out."

Currently, only three Uchiha are known to be alive in the entire Ninja World!

He fixed his gaze on Kou's roguish yet handsome face, as if repeatedly confirming something.

After a moment, hope seemed to understand something, and her usually calm and composed face began to tremble.

"Could he be...?"

Kou slowly turned his gaze to the burly man silently watching him, a feigned surprise curving his lips.

"The Raikage's right-hand man... No wonder you went to such Chakra to chase me, it turns out you had people guarding this place all along."

He shrugged, his tone carrying a hint of feigned helplessness and self-deprecation:

"First, they used close-range pursuit to force me to constantly deplete my Chakra, then they had their subordinates, who were already prepared at the exit, intercept me, creating a sandwich effect on me (intentionally)... What a brilliant tactic."

"Is it really worth the village's Kage going to such lengths to deal with a mere missing-nin like me?"

The Fourth Raikage looked at Koko without hesitation and said frankly:

"This setup was originally prepared for that guy Orochimaru."

However, using it to deal with you now is definitely worth the money.

He paused, then, meeting Kotori's deep Sharingan, said in agreement:

"You don't need to underestimate yourself; your worth is far greater than you think."

"After all, you are rightfully the fastest Ninja World right now!"

Ai Ying, facing the shocked gazes of her two subordinates, solemnly uttered the name:

"Black Lightning - Uchiha Kuro!!"

P. S.: I made a character illustration of the main character and posted it in the book circle. Will everyone be able to see it?

It seems like I can't see this in the book community. I'll try posting an author's note.
