Reborn Naruto: Starting with its own system

At this time, Naruto finally found a quiet place in the forest after many twists and turns. Then, he couldn't wait to open the seal book in his hand. The seal book recorded in detail many mysterious ninjutsu such as Multiple Shadow Clone Technique, Eight Gates of Ninjutsu, Impure World Reincarnation, Flying Thunder God Technique, Flying Thunder God Slash, Mutual Explosion Talisman, Shikigami Fuujin, Four Symbols Seal, etc.

Afterwards, Naruto no longer hesitated, and decisively swallowed a enlightenment pill, concentrating on learning various ninjutsu. He looked focused and resolute, and devoted himself to the understanding of these ninjutsu.

After about an hour, Naruto had mastered all the ninjutsu in the Sealed Book. He slowly closed his eyes, reviewed the contents of the Sealed Book in his mind, and then gently closed the Sealed Book. Then, Naruto raised the corners of his mouth and revealed a confident smile: "The Sealed Book is nothing more than this. For me now, it is just the icing on the cake."

Just when Naruto was secretly proud of himself, a slight sound suddenly came from all around. He opened his eyes alertly and shouted in a low voice: "Who?"

However, as the person approached, Naruto finally saw his face clearly. It was Iruka. He stood with his hands on his waist in anger and shouted at Naruto who was sitting on the ground: "Hey, Naruto! Look at what you have done!"

Naruto scratched his head in embarrassment, and laughed playfully, "Teacher Iruka, I'm surprised you found out. I actually just learned a ninjutsu."

Teacher Iruka's face was filled with disbelief. He stared at Naruto with wide eyes and said, "Learning ninjutsu here? You are simply making a fool of yourself!"

"Oh, Teacher Iruka, I just learned a super powerful ninjutsu from this scroll. If I can learn all the ninjutsu in it, you will let me graduate from the Ninja School and become a real ninja, okay?" Naruto said proudly.

When Mr. Iruka heard this, his mouth opened slightly in shock. He looked at Naruto and asked, "Naruto, who told you that?"

"Of course it was Mizuki Sensei. He was the one who told me where the Book of Seals was kept. He also said that as long as I learned these ninjutsu, I would be able to graduate from the Ninja School and become a ninja."

At this moment, Iruka finally realized something was wrong. Just as he was about to say something more, several sharp kunai suddenly flew out from the depths of the forest. Iruka pushed Naruto away without hesitation, but he himself was unable to dodge, and all the kunai hit him accurately.

Then, a sinister voice sounded slowly: "I didn't expect you to appear here, Iruka."

At this time, Iruka completely understood the truth of the matter, and said with gritted teeth: "So that's it, Mizuki, all of this is a conspiracy you carefully planned."

Mizuki sneered contemptuously, and did not respond to Iruka's questioning. Instead, he turned his gaze to Naruto and threatened: "Naruto, hand over the scroll to me obediently, and I can spare your life."

Seeing this, Iruka gasped and shouted anxiously: "Naruto, you must not give the scroll to him! This scroll contains many powerful ninjutsu. Once it falls into his hands, it will lead to unimaginable consequences. He has been using you from beginning to end, using you to steal this scroll. Run quickly, run back to the village, I will hold him back!"

Naruto stared at the injured Iruka with eyes wide open in disbelief. His heart was instantly filled with a warm current of emotion: "Teacher Iruka..."

Seeing this, Mizuki's face turned ferocious again, and he said viciously: "Naruto, Iruka is afraid that you will get the scroll! Let me tell you the truth. The rumor that circulated in the village a few years ago that you are the nine-tailed demon fox that scourged the village 12 years ago is true. Moreover, it was that demon fox that killed Iruka's parents, and he has always held a grudge against you. Iruka has never truly recognized you, and his heart is full of hatred for you, Naruto."

Naruto looked at Shuimu calmly with a sharp gaze, and snorted in his heart: "Damn you Shuimu, if I wasn't a time traveler and knew the development of the plot, I would really believe your lies."

At this time, Iruka's thoughts drifted away, recalling what the Third Hokage had said, and recalled his childhood experiences: "Iruka, Naruto has never experienced the love from his parents. He usually looks well-behaved and sensible. But only he knows the pain in his heart. Isn't it the same for me? Since my parents passed away, I have never received attention from others. I also deeply understand the loneliness that goes deep into my bones. I'm sorry, Naruto, you must be very lonely too."

At this moment, Mizuki looked at Naruto who seemed to be in a daze, and quickly picked up the Fuma Shuriken and threw it at Naruto with lightning speed.

Iruka on the side finally woke up from his dream, reacted, and ran towards Naruto without hesitation, shouting at the top of his lungs: "Naruto, get down!" Just when the wind shuriken was about to reach Naruto, Iruka rushed forward and stood in front of Naruto without hesitation.

Naruto looked at the figure standing in front of him, and the emotion in his heart was like a surging tide that he could not suppress. Time seemed to freeze, and as the sharp wind demon shuriken was about to pierce Iruka's back, Naruto instantly performed the teleportation technique and pulled Iruka aside.

With a "clang" sound, the Fuma shuriken was nailed deeply into the ground.

Iruka came back to his senses from the shock and looked at Naruto in amazement.

Naruto smiled brightly, looked at Iruka-sensei and said, "Thank you, Iruka-sensei. Leave the rest to me."

Naruto turned around and looked at Mizuki with a cold gaze, "Ant, I have played with you long enough, let's end this."

Then Naruto quickly began to form the "Wei-Si-Yin" seals with his hands, and then a series of "bang bang bang" sounds came from the forest. After a burst of thick smoke, thousands of Naruto clones appeared in the forest like a tide.

Mizuki stared at the shocking scene in front of him, and finally fell into extreme panic. He tried to turn around and run away, but it was too late. Countless Naruto clones rushed over and punched and kicked Mizuki like a storm. In a moment, Mizuki had collapsed to the ground like a dead dog, motionless.

Iruka stared blankly at what was happening before his eyes, unable to believe that this was something Naruto could do.

At this time, Iruka slowly stood up, walked to Naruto, carefully took out a forehead protector from his pocket, handed it to Naruto, and said with relief in his eyes: "Naruto, congratulations on your graduation."

Naruto took the forehead protector with great excitement, tears sparkling in his eyes, and said firmly: "Teacher Iruka, I will definitely become an outstanding ninja!"

Inside the Hokage Building, the Third Hokage was watching everything that was happening in front of him through the crystal ball, a pleased and knowing smile on his face.
