The upgrade system of all realms starts from conquering Naruto

"What kind of teacher will he be? Although I know that the standard teacher is a chuunin, the one who teaches us should at least be an elite among chuunin!"

Natsume Chao only cares about what kind of person the teacher who teaches them will be. As for how soon he will come and whether he will come, it has nothing to do with him.

Anyway, he can sit still, and he doesn't care if he is allowed to sit until night.

"Hey, how about we compete at the seventh training ground later?"

Just when Natsume Chao was about to close his eyes and rest his mind, Uchiha Sasuke's voice suddenly came to his ears, and then, his front became dark.

"No interest, you are too weak!"

Uchiha Sasuke thought that he would not refuse Natsume Yang if he issued the challenge in person, but who would have thought that Natsume Shio refused him with an extremely calm tone without even opening his eyes.

"You guy, don't go too far. Who are you calling weak? Don't think that because your chakra score is high, you can get carried away in front of me. It is just to test your chakra and does not represent your actual combat power. !”

Upon hearing this, Uchiha Sasuke became angry.

"Promise him!"

"Promise him!"

When the people around him saw this, they immediately started making noises. It would be a fool not to watch the excitement.

"How about it, if you are a man, give me a show, don't let me look down on you!"

When he saw the surrounding people starting to boo, Uchiha Sasuke suddenly showed a proud smile. He didn't believe that Natsume Chao still didn't agree to him.

"Since you are looking for abuse, then I will reluctantly agree to it. However, let's make an agreement first. Don't deny it if you lose!"

Natsume Chao scratched his ears. These people were really noisy. He thought that if he didn't agree, they would keep making noise.

"Okay, then it's a deal!"

Upon hearing that Natsume Chao agreed, Uchiha Sasuke suddenly showed a happy expression.

Yesterday, he pestered Uchiha Itachi who had just learned the Go Fireball Jutsu, but he didn't believe it. Natsume Chao also learned Ninjutsu.

"Ahem, cough, cough, students, please calm down!"

Finally, the teacher who had made Naruto and the others wait for a long time finally arrived. He was a young chuunin with a scar on his nose.

It was none other than Iruka Umino, who had important enlightenment significance for Naruto in the original work.

However, logically speaking, Naruto and the others' mentor should be Natsume Yo, so why did he suddenly become Iruka?

This requires setting the time back half an hour.

Natsume Yang suddenly thought that he didn't need to be an instructing Jonin, but there was no need to be a ninja teacher teaching students.

Therefore, he strongly recommended Umino Iruka to the Third Hokage on the condition that he must be free and live as an ordinary jounin.

"Let me introduce myself first. My name is Umino Iruka. You can call me Iruka-sensei!"

Iruka is still a somewhat shy young man, and it is inevitable that he will be a little shy when leading a class for the first time.

"Today is the first time we all meet, so come with me to the seventh training ground and let everyone get to know each other!"

For the first class, Iruka chose the open seventh training ground.

Because the first class in the ninja school is to introduce yourself and then do physical training!

"Everyone, please introduce yourself first, starting with you!"

Iruka caught Uzumaki Naruto in the crowd at a glance!
