Naruto: I, Naruto, started with the Rinnegan

"So, what kind of ninjutsu do you want to learn?"

Kakashi wanted to hear what these two genius students had to say.

Sasuke pondered for a moment and said, "I need advanced Lightning Release and Fire Release ninjutsu."

Low-level ninjutsu is no longer of any use to him.

"Alright then... I'll teach you an A-rank Lightning Release ninjutsu first."

All I can say is that he is indeed a Konoha technician who knows thousands of ninjutsu, and he casually throws out an A-rank ninjutsu.

However, it wasn't the Chidori that Naruto guessed, but rather the Lightning Release: Shadow Clone Technique—a shadow clone created using Lightning Release chakra. When attacked, it generates a flow of Lightning Release chakra to launch an attack on the opponent, paralyzing their body.

Sasuke went to practice ninjutsu on the other side of the training ground, leaving Naruto and Kakashi behind.

Seeing Kakashi's questioning gaze, Naruto said, "Sensei, teach me everything you know."

Kakashi frowned: "Don't bite off more than you can chew. I know a lot, and you can't possibly learn it all."

"How will you know if you don't try?"

Let's give it a try.

.........

"This is Earth Release: Earth Flow Wall..."

After explaining, Kakashi performed Earth Release: Earth Wall by forming hand seals. Naruto immediately said, "I've learned that, next."

Kakashi didn't believe him: "Then show me."

Rumble!

The ground trembled violently, and a long crack appeared, from which emerged a huge wall, hundreds of meters high, blocking out the sky and dividing the spacious training ground in two.

Kakashi was momentarily stunned. He looked up at the giant wall, then pointed at Naruto, his hand trembling. "You...you...you're really human?!"

You've made a B-rank Earth Release ninjutsu even more outrageous than an S-rank one!

Naruto immediately became unhappy. "Kakashi-sensei, are you doubting my dad or my mom?"

teacher?

Master's wife?

Kakashi jolted, then quickly shook his head: "No, I mean... how did you manage to use this ninjutsu like that?"

"Is it a problem that I have a large amount of chakra?"

It seems... there's no problem.

"How did you learn so quickly? You got it after just one take?"

"As everyone knows, I am a genius."

Kakashi was speechless. Just then, Sasuke and Sakura ran over the wall.

"What's going on? This wall..."

Seeing Kakashi looking at Naruto, the two realized that it was Naruto who had done it.

Sakura was stunned. Sure enough, her judgment when she was a child was correct; this was a monster.

Sasuke's jaw clenched. Naruto, just how much more power are you hiding?!

.........

To avoid disturbing Sakura and Sasuke's training, Kakashi took Naruto to another deserted training ground.

"This is Water Release: Water Dragon Bullet..."

The next moment, dozens of huge water dragons flew in the sky.

"You've learned that, next one."

"This is Lightning Release: Chasing Fang..."

The next moment, the lightning-escape form, tens of meters tall, shot out like a streak of light, destroying a large area of ​​forest.

"You've learned that, next one."

"This is Fire Release: Great Dragon Fire... Wait, Naruto, unleash it towards the sky!"

The next moment, a hundred-meter-long dragon head of flame shot straight into the sky, dyeing half of the sky above Konoha red.

"You've learned that, next one."

"This is... let's make this clear first, it's going to be aimed at the sky... this time it's Wind Release: Wind Cutter Technique..."

The next moment, countless wind blades shot into the sky, cutting the large white clouds into tiny pieces.

After waiting a while and seeing Kakashi not continue teaching, Naruto said impatiently, "Keep going, Kakashi-sensei! Five ninjutsu techniques? That's not even enough to fill my teeth."

Kakashi slumped to the ground, panting, "I...I can't go on, let's do it another day."

He used up too much chakra today, and he can't hold on much longer.

"Okay, then tomorrow."

"I meant another day, not tomorrow..." Kakashi wanted to say it, but seeing the Rasengan in Naruto's hand, he could only keep his mouth shut.

With Minato's training memories, Kushina's teachings, and other sources of knowledge, Naruto has mastered a great many ninjutsu.

However, none of this stopped him from his plan to empty Kakashi's coffers, because Kakashi, who had mastered a thousand ninjutsu, was a huge treasure in his eyes.

Through the Rinnegan, Naruto has been infusing his chakra with ninjutsu knowledge over the years, and now his chakra has grown into that of a ninjutsu master.

then……

"Chakra, you've grown up. It's time for you to learn how to train on your own."

When a certain ninjutsu is input into chakra, the chakra deduces and optimizes the ninjutsu based on past ninjutsu knowledge, and the result is fed back to Naruto's mind.

After that, Naruto can either use his hands to perform this ninjutsu or command his chakra to perform it automatically.

The speed and optimization of this ninjutsu depend on chakra or Naruto's knowledge of ninjutsu.

The more and the more varied, the better!

It is obvious that Kakashi's thousand ninjutsu greatly supplements the knowledge system of chakra.

Kakashi didn't hold back either. Because of his guilt for not keeping his promise to Minato, he readily agreed to teach Naruto ninjutsu, even handing over his signature ninjutsu, Chidori.

Sasuke also learned Chidori, and he felt that this ninjutsu was very suitable for him.

Sakura learned Water Release: Water Chaos Wave, and as for other ninjutsu...

Due to limitations in chakra reserves and physical fitness, she had neither the time nor the need to learn, and focused her energy on physical training.

Training and cultivation, completing D-level missions—and so, time slowly passed.

……

A month later.

Kakashi was surprisingly not late for the training ground where Team 7 usually assembles.

"What ninjutsu will we learn today?"

By learning ten ninjutsu every day, Naruto has now obtained 300 ninjutsu from Kakashi, a truly remarkable achievement.

"I won't teach you ninjutsu today; I'll teach you everything I can."

Kakashi was feeling a bit tired. It wasn't good for students to be too outstanding; there wasn't much to teach them.

"lie!"

Naruto didn't believe him: "You're Konoha's number one technician, the Copy Ninja who claims to have mastered a thousand ninjutsu, what about the other seven hundred?"

Top Technician?

A thousand ninjutsu techniques?

Sakura and Sasuke were filled with surprise; it was the first time they had realized that the guy who liked reading erotic novels seemed to be very strong.

"You won't be too sad to part with it, will you?"

Naruto added.

Kakashi's eye veins twitched. "I've given you my life savings, and you say I can't bear to part with it..."

He felt like hitting someone, but sadly, he seemed unable to win.

Kakashi sighed, "I have mastered a thousand ninjutsu, but most of them are minor ninjutsu with limited usage conditions, so they are basically useless. Learning them is a waste of time."

Naruto insisted, "Have you forgotten my learning speed?"

He didn't need to use his brain at all; he just inputted what he heard and saw into his chakra, and then he mastered the ninjutsu.

Kakashi sighed and forced a smile. "Fine, but I don't want to teach you. Let's do it another day."
