Reborn Naruto: Starting with its own system

Konoha, inside the Hokage building. An Anbu ninja appeared in the Hokage's office without warning, then knelt on one knee and reported solemnly: "Sir, there is an incident in the Vigilance Department!"

After hearing what the ninja said, the Sandai stood up abruptly and asked anxiously, "What happened? Did the Uchiha rebel?"

"No, Sandaime-sama, the Uchiha have not yet rebelled, it's just that a huge explosion occurred over at the Guard Department."

The third generation's eyes fixed, and he asked, "Are there any casualties?"

"It's not clear yet. Various departments are already rushing over there."

The third generation looked out the window, paused for a moment and said, "Let's go and take a look at the scene."

On the other side, Sasuke had just finished training and was returning home happily. Suddenly, he saw a fireball rising up in the distance like a giant sun. Then, a deafening explosion sounded. Just as Sasuke was stunned, a powerful air wave rushed over and knocked him to the ground in an instant. After about 5 seconds, Sasuke quickly got up and ran towards the direction of the security department without hesitation. When he ran to his destination, he was instantly stunned by the scene in front of him.

The guard department, which was originally heavily guarded, was now in ruins. Buildings collapsed, smoke billowed, and flames shot up into the sky. The ground was littered with broken rubble and twisted metal debris. Sasuke widened his eyes, his face full of disbelief and shock.

Sasuke took a deep breath, trying his best to calm himself down, and then began to anxiously search for any survivors in the ruins.

However, when he found the dead people, Sasuke once again had a very bad premonition in his heart, because he keenly realized that these deaths were not caused by the explosion, but were brutally killed by sharp weapons.

At this moment, Sasuke felt a strong sense of uneasiness in his heart, as if an invisible net was tightly enveloping him. So, he ran towards the clan without hesitation. But the moment he stepped into the clan, an even more terrifying emotion suddenly rushed into his heart like a surging tide. Quiet, too quiet! Not to mention that such a strong explosion occurred not far from the clan, even on normal days, the entire clan should not be so terribly quiet at this time.

Sasuke didn't hesitate for a moment and ran quickly towards his home.

As Sasuke stood in front of the door, the uneasiness in his heart grew stronger like a surging wave.

Sasuke took a deep breath, trying to suppress the uneasiness in his heart. However, his shaking hands reaching for the door mercilessly betrayed his inner fear and panic.

"Creaky", the door opened.

The moment Sasuke opened the door, he was struck by lightning and stood there in shock. His eyes were wide open, his pupils shrank sharply, and the muscles on his face twitched with extreme fear.

Inside the room, the strong and nauseating smell of blood hit me. The originally warm and tidy room has now become a miserable battlefield. The furniture is scattered, the broken vases, the overturned tables and chairs seem to tell the story of the brutal fight that just happened. On the ground, the messy bloodstains are like winding snakes, shocking, and there are deep scratches and broken kunai left by the fight.

His father, Uchiha Fugaku, once had a majestic and upright figure, but now he collapsed to the ground helplessly. His eyes had lost their former luster, and were empty and lifeless. His tightly furrowed brows seemed to still retain the pain and unwillingness before his death. Blood continued to flow from his chest, staining his clothes, which symbolized the glory of his family, bright red.

The mother, Uchiha Mikoto, lay beside her father, her beautiful face as pale as paper, tears dried on her cheeks, leaving two clear traces. In her eyes, there was no longer the tenderness and kindness of the past, only endless concern for the children and helplessness about this cruel fate.

In the dark corner of the room, Itachi stood quietly, his figure half-hidden by the darkness. His eyes were as cold as ice, so deep that no one could see through them, as if they were an endless dark abyss. The blood-stained blade in his hand flashed a strange cold light in the weak light, and blood slowly dripped down the blade, and each drop made a crisp and terrifying sound in the silence.

"Itachi...why?" Sasuke's voice trembled, as if squeezed out from the depths of his soul, full of despair and confusion.

Itachi slowly turned his head and looked at Sasuke. There was still no warmth in his eyes, only chilling determination and coldness. Suddenly, Itachi's Mangekyō Sharingan shone brightly, and Sasuke was instantly pulled into an illusion.

In the illusion, Sasuke saw Itachi ruthlessly killing his fellow tribesmen one by one. The cruel scene made him feel extremely painful. The screams of the people and the splashing of blood, every detail was extremely clear.

"See this clearly, stupid brother. This is reality." Itachi's voice echoed in the illusion.

Sasuke collapsed and yelled: "Why did you do this? We are a family! We used to laugh together and live together, why can you be so cruel?"

Itachi replied coldly: "Family? In this ninja world full of blood and fighting, so-called family is nothing more than the comfort sought by the weak. Only by possessing absolute power can you control your own destiny."

Sasuke burst into tears and screamed hysterically: "I will definitely take revenge, Itachi! I will practice day and night, I will make myself extremely powerful, and I will make you pay a heavy price for what you did today!"

Itachi was silent for a moment, a barely perceptible pain flashed across his face, but he immediately returned to his indifference: "Then work hard to become stronger, Sasuke. But remember, before you become truly powerful, you are nothing more than an ant in this world."

After saying that, Itachi's figure disappeared quietly into the darkness like a ghost, leaving Sasuke alone in this room full of despair and pain, crying heart-wrenchingly and gut-wrenchingly, as if the cry was going to tear the whole world apart.

In the forest, Naruto and Shisui, both wearing masks, stood side by side in front of a group of Uchiha clan members.

At this time, Uchiha Izumi walked up to the two of them and asked anxiously, "Senior, Itachi has been gone for so long and hasn't come back yet, is there anything wrong?"

Naruto looked at Izumi and was about to speak when Itachi appeared in front of everyone. Itachi looked around and felt a deep sense of remorse. There were still dozens of radicals who chose to fight, including his own father. And his mother, in order to follow his father, also chose to die. At this moment, Itachi's heart seemed to be pressed by a ton of rocks, so heavy that he could hardly breathe.

Naruto noticed Itachi's painful expression and knew that he was upset, so he advised: "Itachi, don't take it to heart. After all, it is the path they chose themselves. We can only sacrifice our small selves to achieve the greater self. As for your parents, you don't need to worry. You also know my abilities. Now is not the time to be sentimental. There are still many people in our tribe who are not out of trouble yet."

Itachi looked at Naruto hopefully and said, "Senior, the remaining members of the clan are all here. I'll leave the rest to you."

After listening to Itachi's words, Naruto nodded slightly. Then, he turned his gaze to the Uchiha clan members.

But the next scene was something that Itachi, Shisui and all the Uchiha clan members would never forget.

Naruto slowly closed his eyes, and when he opened them again, a pair of white Mangekyō Sharingan suddenly appeared before everyone's eyes.
