Reborn Naruto: Starting with its own system

Naruto looked at the person who appeared beside him and couldn't help but said speechlessly: "Sasuke, why are you here?"

Sasuke stared at Itachi intently, his eyes seemed to be burning with rage, like a ferocious beast, vowing to cut the prey in front of him into pieces. But even so, he still answered Naruto's question: "I saw the note you left in the room. I went to the hospital to visit Kakashi, but I didn't expect to hear their conversation. It was him, Uchiha Itachi, who injured Kakashi. Then I asked along the way, and the uncle told me that you were here. I didn't expect Uchiha Itachi to follow here."

Sasuke's words were filled with anger and determination, his body trembling slightly, his hand tightly holding the kunai. The hatred between him and Itachi was like a surging tide, constantly impacting his heart.

Naruto looked at Sasuke who was already furious, knowing that he might not be able to suppress his anger. But this was the center of the village after all, and if a war broke out, the whole village would probably be affected.

Then Naruto no longer hesitated, his pupil power spread, and his Mangekyō Sharingan opened. The Spiritual Realm was activated directly. Then, the five people suddenly appeared in a snowy land. The biting cold wind was howling, rolling up the snowflakes all over the sky, and the ground was covered with silver. Sasuke was slightly startled, and then his eyes became colder. He knew that this was a measure taken by Naruto not to let the battle affect the village. Itachi still looked calm, and seemed not surprised by this sudden change. Kisame frowned and observed the surrounding environment vigilantly.

In this icy and snowy place, the atmosphere became increasingly tense. Sasuke held the kunai tightly and walked towards Itachi step by step, each step seemed to carry endless hatred. Itachi looked at Sasuke quietly, with complex emotions in his eyes.

Soon, Sasuke and Itachi collided violently. Sasuke's Lightning Release was like a violent lightning, constantly striking Itachi, and the air was filled with a burning smell. Itachi responded calmly, using the flame shield formed by the Fire Release Technique to resist Sasuke's Lightning Release attack.

The Navy Six Styles showed amazing power in the hands of the two. Sasuke's Moon Step allowed him to move flexibly in the air, constantly changing the angle of attack. The finger spear stabbed at Itachi like a storm, and each attack contained endless anger. Itachi cleverly dodged Sasuke's attack with the shaving technique, and counterattacked with the Storm Kick, and the powerful energy knocked the surrounding ice and snow away.

Their fight seemed like a duel of life and death, with every move and style full of strength and skill. Sasuke's eyes were burning with the flame of revenge, and he attacked Itachi desperately, trying to release the hatred he had accumulated over the years. However, Itachi's eyes were filled with indescribable complex emotions, he didn't want to hurt Sasuke, but he had to face Sasuke's attack.

In the ice and snow, the two figures were like two lightning bolts, constantly crossing and colliding. Their battle caused drastic changes in the surrounding environment, and the ice and snow were splashed everywhere by the powerful force.

On the other hand, Naruto's side was like a visual feast. The powerful ice escape was directed at Kisame again and again, and the ice-blue light shone in the ice and snow, like a dazzling ice crystal storm. Kisame waved Samehada and struggled to resist Naruto's continuous ice escape attacks. Every collision made a deafening sound, and ice chips and energy waves scattered everywhere.

Naruto's eyes were firm, his hands quickly formed seals, and the power of ice escape continuously flowed out of his body. He controlled the ice pillars to pierce Kisame like a sword, or condensed a huge ice wall to try to block Kisame's attack. Kisame roared, relying on his powerful strength and the special ability of Samehada to continuously dissolve Naruto's ice escape.

Their battle was like a contest of ice and strength. Naruto showed his outstanding control of ninjutsu, while Kisame responded with his fierce fighting style and powerful strength. In this icy and snowy land, their battle became a unique landscape, which made people marvel at the magic of ninjutsu and tense for their fierce confrontation.

Jiraiya, who was standing nearby, got a bunch of food from somewhere. He deftly shaved a huge block of ice and made it into a table and chairs. Jiraiya sat there leisurely, watching the two young Konoha Genin deal with the two S-rank rebels.

While eating, he occasionally commented on the two's skills, ninjutsu, and taijutsu. "Well, Naruto can actually use Ice Release Bloodline Genkai, but he still has to be careful to control the output of chakra." Then he looked at the battle between Sasuke and Itachi, "Sasuke, this kid, his coordination of Fire Release and Lightning Release is quite good, but he is still too impatient when facing Itachi."

Jiraiya's comments echoed in the snow, like an experienced instructor instructing a student. He had a relaxed smile on his face, and he didn't seem to be worried about the situation. However, a trace of vigilance flashed in his eyes from time to time. After all, he was facing two powerful rebels, and unexpected situations could occur at any time.

Under Jiraiya's watch, Naruto and Sasuke continued to fight fiercely with Kisame and Itachi. Their figures shuttled through the ice and snow, and the collision of the light and power of ninjutsu made this world full of tension and excitement.

As time went by, the two sides seemed to be in a stalemate. Itachi was sighing at Sasuke's growth. Seeing this once immature boy now possessing such a powerful strength, he had mixed feelings in his heart. Sasuke wanted to kill Itachi directly, and the flame of hatred burned more and more fiercely in his heart.

As for Naruto and Kisame, they were still exchanging ninjutsu. The power of Ice Release and Samehada continued to collide, and snowflakes and water vapor intertwined.

Until a certain moment, Itachi finally couldn't help himself and activated the Mangekyō Sharingan when he and Sasuke were in a stalemate. In an instant, Sasuke stood there as if he had lost his soul. His eyes were empty, as if he was controlled by a powerful force. The power of the Mangekyō Sharingan made the air around him seem to solidify, and the powerful illusion made Sasuke fall into deep confusion.

Jiraiya, who was standing by, saw this scene and felt his heart tighten. He couldn't help but frown. He knew that Sasuke might have fallen into an illusion, and he was worried that Sasuke would fall into a dilemma from which he couldn't extricate himself.

Naruto, who was standing by, couldn't help but sigh when he saw this scene: "Itachi, you really don't hold back on your brother." Then he put away his thoughts of playing and formed a seal with his hands - a white whale. A huge narwhal several hundred meters long appeared in an instant and crashed straight into Kisame.
