Reborn Naruto: Starting with its own system

Naruto collapsed on the bed, feeling exhausted instantly. Just when he wanted to have a good sleep, a figure appeared outside the window. "Naruto-kun, I'm so sorry to bother you." Hearing the call, Naruto got out of bed and came to the window.

"Itachi, is there something you want to talk to me about?" Naruto asked curiously.

Itachi replied hesitantly, "Naruto-kun, I have basically mastered the Marine Six Styles that you taught me. I came here this time to spar with you again."

Naruto looked at Itachi's serious look and couldn't help but sigh at Uchiha Itachi's talent. He was indeed a genius of the Uchiha clan. He learned the Navy 6 Styles in just one year.

Then Naruto said, "Okay, then you go to the training ground in the forest first, I'll be there soon."

Itachi nodded, turned around and ran quickly towards the training ground. Naruto looked at his back and recalled the scene when he taught Itachi the Marine 6 Style. At that time, Itachi repeatedly pondered every move and every detail, practiced hard, and showed extraordinary perseverance and determination.

Naruto cleaned himself up a bit, stretched his body, and headed to the training ground to prepare for Itachi's challenge. He was looking forward to seeing Itachi's growth and progress over the past year.

A breeze blew through the training ground, blowing up leaves. Naruto and Itachi stood on either side.

The leaves slowly fell between them, and the atmosphere seemed a little solemn. Naruto looked at Itachi with a firm gaze, secretly assessing his opponent's strength in his heart. Itachi, on the other hand, looked focused, and his eyes revealed a strong fighting spirit.

Itachi took the lead in attacking, and in a flash, he used the "Shave" to instantly appear in front of Naruto, and stabbed him with a "Finger Gun". Naruto reacted quickly, dodging sideways, and at the same time forming seals with both hands, shouting: "Fire Style: Great Fireball Jutsu!" A huge fireball flew towards Itachi.

Itachi was not in a hurry, and performed "Paper Painting", his body was as light as paper, avoiding the attack of the fireball. Then, he jumped into the air with a "Moon Step", ready to launch an attack from above.

Seeing this, Naruto formed seals with his hands again, "Ice Style: Ice Pillar Technique!" Several sharp ice pillars rose from the ground and headed straight for Itachi in the air. Itachi flexibly changed his body shape in the air to avoid the ice pillars.

I was horrified, "Naruto-kun can actually use the Ice Release Bloodline Genkai."

After landing, Itachi threw away all thoughts in his mind and immediately rushed towards Naruto, using "Iron Block" to forcefully break through Naruto's defense. However, Naruto did not engage him head-on, but shouted: "Storm Legs: Flame Blade!" A wind blade with flames flew out from under his feet and rushed towards Itachi.

Itachi quickly used the "Shave" to dodge, and then distanced himself from Naruto. Naruto took advantage of the situation to chase after him, "Ice Style: Ice Dragon Bullet Technique!" A huge ice dragon roared and pounced towards Itachi.

Itachi's eyes focused and he quickly formed seals with his hands, "Fire Style: Phoenix Flower Technique!" Countless fireballs collided with the ice dragon, stirring up a cloud of smoke and water vapor.

The battle between the two became more and more intense, and the air around them became a mixture of hot and cold due to their powerful ninjutsu.

In the smoke and steam, the figures of Naruto and Itachi were looming.

Taking advantage of the cover of the smoke, Naruto quickly changed seals with his hands, "Fire Style: Fire Dragon Flame Bomb!" A blazing fire dragon spewed out of his mouth and rushed straight towards Itachi in the smoke.

Itachi snorted coldly, "Water Style: Water Wall!" A huge water curtain appeared out of thin air, blocking the fire dragon's attack. The water and fire intersected, instantly generating a large amount of steam, and the training ground became white.

When the steam dissipated a little, Itachi instantly used "Shave" and appeared behind Naruto, "Finger Gun!" The finger gun attack quickly attacked Naruto.

Naruto sensed the danger behind him and lunged forward, shouting, "Ice Release: Ice Mirror!" A huge ice mirror formed behind him, blocking Itachi's finger gun.

However, Itachi's attack did not stop, he performed the "Moon Step" again, leaped into the air, "Fire Style: Great Dragon Fire Jutsu!" A huge flaming dragon swooped down towards Naruto.

Naruto clasped his hands together and said, "Ice Release: Absolute Zero!" The temperature around him dropped sharply, and the giant flaming dragon was instantly frozen when it approached him.

At this time, Itachi felt helpless. Naruto was too strong. All the ninjutsu he used were countered by Naruto. Even if he learned the 6 styles of the Navy, he was still no match for him. Itachi knew that Naruto had not yet used his full strength.

Itachi formed a seal again, "Fire Style: Dragon Flame Song Jutsu!" Several giant flaming dragons roared and rushed towards Naruto. Naruto was not in a hurry, "Ice Style: Ice Prison Jutsu!" In an instant, a huge ice prison trapped the giant flaming dragons.

The flames raged in the ice prison, but could not break through the solid restraints. Seeing this, Itachi gritted his teeth, flashed, used "Shave", and instantly approached Naruto, trying to launch a close-range attack.

Naruto reacted quickly, dodging sideways and punching back. Itachi blocked with his arm, but was knocked back a few steps by the powerful force.

Itachi gasped for breath, feeling helpless and unwilling: "Naruto-kun, let's stop here. I lose."

Naruto walked forward, stretched out his hand and pulled Itachi up, saying: "Itachi, you are already very powerful. If I hadn't made a breakthrough recently, it wouldn't have been so easy to win."

Itachi smiled bitterly and shook his head: "No need to comfort me, Naruto-kun, your strength is far superior to mine, this is an indisputable fact."

Naruto patted Itachi's shoulder and said, "But your fighting skills and experience have also benefited me a lot. This sparring match is also a good training for me."

Afterwards, the two of them quickly set up a grill in the training ground, placed two pieces of venison on it, and began to sizzle over the jumping flames.

The two of them talked happily, just like old friends. After a year of getting along and teaching, Itachi respected Naruto like a teacher. He did not look down on Naruto at all because Naruto was only 4 years old.

Itachi looked at Naruto's eyes full of energy and wisdom, and secretly sighed in his heart: "Although this child is still young, he has strength and intelligence far beyond his peers. His future is limitless."

Naruto was flipping the venison skillfully while enthusiastically describing his new ideas about ninjutsu. His lively appearance made Itachi couldn't help but smile.

In this warm atmosphere, the flames illuminated their faces, as if time had stopped at this moment, leaving only this sincere friendship and the rising scent of fireworks.

When they parted, Naruto suddenly turned to Itachi and said, "Itachi, if possible, you must not join the Anbu in the future, and especially stay away from that guy called Danzo."

Itachi was slightly startled, looked at Naruto in confusion, and asked, "Naruto, why are you suddenly talking about this?"

Naruto looked deep in the eyes and said seriously, "My intuition tells me that it is not a good place to go, and Danzo is a dangerous person. I don't want to see you get into danger and trouble."

Itachi was silent for a moment, then slowly said: "Naruto-kun, thank you for your reminder, I will consider it carefully."

Naruto nodded and said, "Remember, I don't want you to get hurt." After that, he turned and left, leaving Itachi standing there, deep in thought.
