Naruto: Starting with the Two Kamui

However, due to Orochimaru's forbidden technique in his early years, Itachi and Yu became blood brothers and had some of the power of the Senju within them. As the years have passed, Itachi's chakra reserves are now vastly different from what they used to be!

The power of the Fireball he unleashed was absolutely unparalleled!

Because Sasuke spent five full years in the Twin Moon Space, he is now thirteen years old, only one year younger than Itachi!

In the battle of fire-style techniques, Itachi had the upper hand!

Sizzle! Sasuke's cursed seal on the back of his neck was released, and the power of his Fire Release technique increased dramatically, making him a match for Itachi!

Sensing the sudden surge of flames on the other side, Itachi thought: The sudden increase in chakra must be the power of the cursed seal bestowed upon Sasuke by the shadows. There are three states in total, and this should only be state one at present. There is still a lot of room for improvement!

Itachi subtly increased the frequency of his chakra transmission!

Bravo! His powerful fireball has gained the upper hand once again!

Sasuke thought to himself: He really held back! Is he trying to conserve as much chakra as possible? I'm not going to give him that chance!

*Zzzzzzz!* Sasuke's cursed seal was further unleashed, entering a partially transformed state two, and he was once again locked in a stalemate with Itachi.

Itachi thought that was enough and did not increase the power any further.

The two sides engaged in a tug-of-war with their fireballs, each pushing the other, and after nearly ten seconds of stalemate, they exploded with a deafening roar!

The heat was intense, and the air was thick and hazy!

Bang! !

Sasuke rolled up his sleeve, reached for the hand straps inscribed with a summoning spell, quickly summoned a shuriken, and threw it forward...

There seemed to be some kind of tacit understanding between the brothers, and Itachi also used his signature shuriken technique!

Clang clang clang clang clang! The flames completely dissipated, and the two torrents of shuriken collided in mid-air, sparks flying everywhere, and shuriken fell all over the ground!

"Sasuke's shurikenjutsu is so exquisite. He must have worked very hard all these years..."

With a sigh in his heart, Itachi's hand formed the Shadow Clone Seal in the blink of an eye!

Bang!

White smoke rose from the side, and Itachi's shadow clone leaped into the air and threw a shuriken at Sasuke!

"Even under such intense shuriken combat, he still had the energy to form a shadow clone hand seal!"

Sasuke, startled, tried to block the shuriken with his cursed wings... but with a clang, the shuriken Itachi fired was blocked by the purple bone covering it!

Sasuke was startled, realizing that he had already activated Susanoo!

"So that's how it is. This is Susanoo. Its defensive capabilities are indeed impeccable. No wonder the Shadows were willing to use it! Hmph!"

Sasuke smirked, stopped throwing shuriken, and rushed forward, using his Susanoo to block the shuriken head-on. He then clenched his fist and swung it forward!

Bang! ! !

The spot where Itachi had just stood was instantly smashed open, leaving a hole. Although his main body escaped unscathed, his clone was instantly blasted to pieces...

"I see... Its attack power is also impeccable!" Sasuke was very satisfied with the power of Susanoo. He looked up at Itachi's main body, who had jumped into the air, and said coldly, "I really have to thank you. If you hadn't tried to sneak up on me with your shuriken just now, I wouldn't have realized that I already had this power!"

Hey!

After somersaulting, Itachi landed and said indifferently, "You look like a child who just got a new toy, childish and ridiculous..."

click!

Sasuke's eyes turned cold, and a purple greatsword materialized in the giant skeletal hand, which he then slashed horizontally... Crack!

As the wind swept past, Itachi leaped up from the spot, his body hovering in the air to avoid the wind, and the wall behind him cracked open with a loud bang!

Click!

The 'Chidori Spear' extending from Sasuke's hand pierced Itachi's body with a series of cracking sounds. Lightning radiated outwards from the edges, exiting from various points along Itachi's body...

Gaa gaa gaa gaa!

The weasel's body scattered into crows!

"Is it your signature genjutsu trick again?" Sasuke stared at Itachi, who was hanging upside down from the ceiling, and lowered his lightning-covered hand, thinking: His genjutsu skills are superior to mine. I need to be more careful with my timing, or I'll just be wasting my chakra...

Itachi, hanging upside down, looked at Sasuke and said, "Even with the same eyes, the things reflected in them are completely different. Sasuke, your power is nothing special!"

"You think this cheap trick of provocation will work on me now?! I told you, I've already seen how you die!!!"

Sasuke's left eye's Mangekyou Sharingan gleamed with bloodshot veins as he focused on Itachi above.

Amaterasu! !

Bear!!

The jet-black flames burst forth, but were blocked by the crimson light rising from Itachi's body!

"Susanoo isn't just your exclusive property!"

As Itachi finished speaking, a crimson hand formed into a skull, and within it, a crimson spear materialized. Itachi cleverly used the Amaterasu that Sasuke had previously released, attaching it to the spear, and then thrust it down fiercely!

This is the divine weapon of Itachi's Susanoo: the Heavenly Spear!

Click!

Sasuke's Susanoo was only in its initial first form. In front of the divine weapon, it was as fragile as paper and was easily pierced. Sasuke sensed something was wrong and dodged to the side. He successfully avoided the attack, but his huge wings in the second stage of the Cursed Seal were pierced by the Heavenly Spear, and Amaterasu's flames clung to them...

"Aa ...

Itachi thought to himself: According to what Lord Shadow said, Sasuke's right eye's power should be...

He said, "This is what they call lifting a stone only to drop it on your own foot. You're being burned to death by the fire you started. How ridiculous!"

"!" Sasuke's heart skipped a beat. He endured the burning pain and looked at the black flames on his wings. His right eye, which had just been activated, suddenly burst out with the unique brilliance of a dojutsu!

call out! !

The black flames have been successfully extinguished...

"Huff, huff, huff..." Sasuke covered his right eye: "So that's how it is, Kagutsuchi, is this the power of my right Mangekyou Sharingan?"

"Hmm?" Itachi feigned surprise and said, "They say Amaterasu is an inextinguishable flame, yet you were able to extinguish it. The power of your eyes is truly remarkable, but giving it to you is such a waste. You should leave it to me, so that I can be like Shadow Uchiha Yu, and like Uchiha Madara back then, forever shining with light!!"

Itachi's Susanoo once again raised the Heavenly Spear!

"Don't even think about it!!!" Sasuke's eyes both focused upwards.

Fire Release: Kagutsuchi!

Click! Click!

Black flames ignited on Susanoo, sharpening into a pointed flame spear that pierced into Itachi's Susanoo...

boom!!!

The ceiling broke open, and Itachi, clad in crimson Susanoo, emerged outside.

Boom!! Sasuke also came outside, activating his purple Susanoo, and stood up to Itachi!

Itachi gazed at the black flames within Susanoo, only centimeters from his body: "This is really dangerous, but..."

Whoosh! He took out a scroll, quickly drew some talismans on it, and formed a hand seal with two fingers.

—Fire-Sealing Seal!

call out! !

The black flames were quickly absorbed into the center of the scroll and sealed away.

Sasuke narrowed his eyes slightly: He was once someone the Shadow Masters valued; the breadth of his ninjutsu skills far surpasses what I can currently match…

He then coldly said, "It's nothing special. The black flames would be enough to burn you to ashes with the time it takes you to cast this spell!"

"Heh." Itachi's lips curled into a smile. "That's just wishful thinking on your part. Just like how you once thought I was a considerate older brother, your eyes, from beginning to end, only saw what I wanted you to see..."

Sasuke frowned and said, "You're just being mysterious!"

Itachi said, "Do you know why I specifically came outside? Was it just to escape the range of your control over the black flames?"

Sasuke's pupils contracted, and a sudden sense of foreboding washed over him!

Itachi pointed and said, "While Susanoo's defensive capabilities are impeccable, unless one awakens the Eternal Mangekyou Sharingan or the Complete Susanoo, they all share the same weakness: their feet!"

"Could it be..." Sasuke looked down at his feet, cold sweat pouring down his back.

Click!

The ground is cracking...

"Oh no!" Sasuke hurriedly tried to dodge.

"It's too late..."

Itachi's shadow clone below finished forming hand seals.

—Wind Release: Wind Blows Through!

Intense wind blades raged inside Susanoo, but the enclosed space created by Susanoo actually concentrated the power of the wind release even more...

"Waaaaaahhhhhh...!!" Under the cutting of the wind blades, Sasuke turned into a bloody mess and lay on the ground, his Susanoo beginning to dissipate.

Whoosh! Itachi casually threw the kunai with the explosive tag attached at Sasuke.

boom!!!

After the explosion, Sasuke lay panting on the ground, protected by the Susanoo skeleton that he had barely managed to maintain.

"What? You managed to leave the Valley of the Netherworld alive? I thought you were some kind of genius. But in the end, you're just this level. You still dare to dream of acting on behalf of Heaven and wielding your blade to slay demons?" Itachi mocked Sasuke.

"Huff, huff, huff..." Sasuke breathed heavily, his eyes unfocused.

"Oh right... I remember now, there were two other children who were lost in the Valley of the Dead with you, right? One was named Uchiha Yuki, the daughter of the Shadow, and the other was named Uzumaki Naruto, the son of the Fourth Hokage..."

Itachi's lips curled into a mocking smile: "The reason you've managed to survive is mainly due to their power, isn't it..."

Click!

Sasuke's eyes widened suddenly, and his five fingers were embedded in the cracks in the stone!

He sees Naruto as his only true friend and a rival to surpass! He has always been chasing after Naruto's footsteps! But every time he sees Naruto break through his own limits, Sasuke may not say it, but he feels extremely resentful inside!

In addition to liking, Sasuke's feelings for Yuki also included a deep-seated inferiority complex!

Itachi, who had been watching his younger brother's growth for years, had long seen through this, so he ignited the fire in Sasuke's heart and added fuel to the fire!

"—That's right, you're no match for them!! You're inferior to them!! You're just a useless piece of trash who's holding us back. Ahh, having a younger brother like you is a disgrace to our Uchiha clan!!!"
