Reborn Naruto: Starting with its own system

Naruto was watching the battle closely on the side. This battle was a huge challenge for Sasuke and Kimimaro, but it was also a great opportunity for them to break through themselves.

Just as the black-robed man was fending off Kimimaro's attack, Sasuke approached him again. He concentrated his spiritual power on the sword, and the sword glowed brightly.

"Chidori Flow!" A powerful electric current surrounded Sasuke's body and rushed towards the man in black robe.

The man in black robe felt this powerful force, and for the first time a trace of solemnity flashed in his eyes. He removed the light curtain, pushed his hands forward, muttered something, and a powerful black vortex formed in front of him and collided with Sasuke's Chidori Style.

In an instant, light and darkness intertwined, and the powerful impact caused everything around to fly up.

As the Chidori Flow and the black vortex collided, the huge impact force spread out in all directions, and Sasuke and the man in black robe were both shocked and retreated.

Sasuke knelt on one knee, a trace of blood oozing from the corner of his mouth. He supported his body with his sword, but his eyes became more determined.

The man in black robe also shook his body slightly, and the expression on his face became even more ferocious.

"Interesting, kid, you're stronger than I thought." The black-robed man said grimly.

Kimimaro took this opportunity to attack again.

He performed the secret art of bone escape, and the bones all over his body grew and deformed rapidly. Countless huge bone spurs extended from his back like wings.

With the help of this force, he rushed towards the man in black robe like a cannonball. The white spiritual power was wrapped around his bone spurs, which was extremely powerful.

Seeing this, the man in black robe raised his hands calmly and chanted an ancient and obscure spell.

In an instant, a layer of black armor appeared around him, with strange runes flashing on the armor.

Kimimaro's attack hit the armor hard, making a deafening roar, but the man in black robe did not move at all. He just sneered and waved his right hand. A black energy whip flew out from his sleeve and lashed towards Kimimaro.

Kimimaro dodged hurriedly, but the energy whip was so fast that it still left a deep wound on his arm.

He frowned, but showed no sign of backing down.

Sasuke stood up, wiped the blood from the corner of his mouth, and rushed towards the man in black robe again.

He pushed his speed and strength to the extreme.

He attacked the black-robed man from behind, stabbing the black-robed man in the back with the sword in his hand.

The man in black robe sensed the attack from behind, and black smoke suddenly emerged from his body. Sasuke's sword pierced into the smoke, but it felt like it was stabbing into empty space.

Soon a man in black robe appeared not far away.

Naruto chuckled and said, "Ordinary ninjutsu will have no effect on him. As a fellow cultivator enemy, you must abandon your original way of fighting."

Sasuke looked grim and nodded slightly. In an instant, a powerful aura as if coming from the abyss began to surge from his body like a surging wave.

The aura spread in all directions like a substance, and wherever it passed, the space seemed to be slightly distorted.

The Kusanagi sword in his hand, with its cold and sharp blade, trembled slightly and made a buzzing sound, as if it had reached some kind of mysterious resonance with the surrounding air.

Every slight tremor seemed to be echoing with some kind of power between heaven and earth. The mysterious runes flowing on the sword were also flashing with a faint light, as if excited for the upcoming battle.

At this breathtakingly tense moment, Sasuke suddenly swung the Kusanagi sword.

At first glance, the movement seemed as gentle as a breeze blowing across a calm lake, with an unexpected elegance.

However, beneath this seemingly gentle appearance, endless mysteries are hidden.

Every swing of the sword reveals Sasuke's exquisite control over strength. Although it seems careless, every slight change in angle and every increase or decrease in strength have been precisely calculated.

Sasuke's swordsmanship is as exquisite as art. He uses his sword as a pen and swings it freely in the air.

Smooth arcs appeared one after another. Those arcs were like the paths of the brightest meteors in the night sky, or like the lines drawn by the mysterious force in the universe, full of beauty and power.

The sword shadows were like wisps of cotton dancing in the breeze, seemingly light and weak, but overwhelming and pervasive, cleverly disrupting the opponent's vision.

Each sword shadow was like an illusion, making it difficult to distinguish between the real and the fake, which made the man in black fall into endless confusion and unable to capture the true direction of Sasuke's attack.

This sword technique is exactly the king-level sword technique that Naruto passed on to Sasuke - Lingxu Sword Technique.

This sword technique is a peerless magic skill, and each move contains the truth of heaven and earth. Sasuke is performing the first move "Gentle Breeze"

At this time, Kimimaro also moved.

He took a deep breath, a look of determination flashed in his eyes, and he began to mobilize the tremendous power in his body with all his strength.

As the power surged, his body trembled slightly, and bone essence was slowly drawn out from deep within his bones.

The essence was like silver threads, quickly interweaving and condensing in his hands, and in the blink of an eye it formed a bone sword emitting a cold light.

The blade of this bone sword is slender, like a nimble snake, with mysterious patterns engraved on it. Those patterns are like ancient spells, or symbols containing the mysteries of heaven and earth, faintly emitting a fascinating power.

At this time, Kimimaro held the bone sword firmly, slowly raised it in front of him, and the tip of the sword pointed straight to the sky.

At that moment, he seemed to have established some kind of mysterious connection with the vast starry sky, as if he was really summoning the power of the stars, to gather the energy of the universe onto this bone sword and inject endless power into the upcoming battle.

Soon, Kimimaro flicked his wrist violently, and the bone sword emitting a cold light rushed straight towards the man in black robe like a silver lightning.

The sword cut through the air, making a sharp whistling sound, and it was very powerful.

At this moment, the man in black robe was concentrating on dealing with Sasuke's "Cool Breeze".

Sasuke's sword shadows disturbed his vision from all directions like light cotton, and he didn't notice Kimimaro's sword at all.

At this critical moment, Kimimaro's sword, with the force of breaking the wind, whistled towards the black-robed man like the scythe of the god of death.

The sharp whistling sound echoed in the air, like a sonata of death, making the atmosphere around them even more tense.

The black-robed man's attention was completely attracted by Sasuke's dreamlike "gentle breeze". Sasuke's sword shadows were like countless light wools, coming from all directions, seemingly real and illusory, and successfully confused his perception.

He was so focused on finding Sasuke's weakness in the shadows that he was completely unaware that Kimimaro's fatal blow, like silver lightning, was rapidly approaching from behind, and the shadow of death had quietly enveloped his head.
