The upgrade system of all realms starts from conquering Naruto

"Is there anyone else who wants to challenge!" Iruka felt that his words were simply provoking trouble!

"I challenge Uchiha Sasuke!"

As soon as he finished speaking, those who had a conflict with Uchiha Sasuke immediately started to challenge Uchiha Sasuke.

"Humph, idiot!"

This time, it was Natsume Chao who had closed his eyes and rested his mind and spoke.

Although he defeated Uchiha Sasuke so easily, it was because of his own strength. For ordinary people, wanting to defeat Uchiha Sasuke was nothing more than a dream!

After all, Ou Doudou, who is also Uchiha Itachi, how could he not have certain strength.

"Ruichi Murashita, please give me some advice!"

Although Uchiha Sasuke was extremely angry when he saw him, there was still a proper ritual.

"start!"

Iruka gave the order, and before Murakami Ryuichi could react, Uchiha Sasuke had disappeared from the place, making him widen his eyes.

"For someone like you to want to fight me, you really think that I, Uchiha Sasuke, are weak, don't you?"

Uchiha Sasuke appeared behind Murakami Ryuichi again, and his whip-like legs came crashing down, causing the air to roar violently.

"How can it be!"

Murashita Ryuichi screamed in shock, this was completely beyond his expectation. He originally thought that Uchiha Sasuke was really weak just like Natsume Chao said, so he dared to challenge him!

But who would have thought that after it was him, Uchiha Sasuke suddenly became so terrifying.

"puff!"

Uchiha Sasuke showed no mercy with this kick. Teacher Iruka even heard the sound of bones cracking, and Murakami Ryuichi flew backwards.

"The battle is over!"

Iruka immediately announced that the battle was over. If it continued, he really couldn't predict what Uchiha Sasuke would do!

"Who else wants to challenge?"

Uchiha Sasuke looked around and asked indifferently.

This time, everyone who had truly experienced the powerful strength of Uchiha Sasuke, no matter how dared to have any thoughts, they all chose to avoid it when Uchiha Sasuke's eyes swept over.

"Hmph, trash!"

Seeing this, Uchiha Sasuke immediately showed a contemptuous smile, then snorted coldly and returned to the team.

"Is there anyone else who wants to continue the challenge?"

After Uchiha Sasuke ended the battle, Iruka asked again.

…

What Ibra received was silence. Seeing this scene, Iruka suddenly felt reassured.

"Okay, in that case, let's end it here today! Let's get familiar with each other again, and then school can be over!"

The first year is relatively easy, and there are basically not too many courses.

"oh!"

As soon as they heard that the class was over, all the children immediately burst into excitement.

"Naruto, let's go!"

After hearing that it was time to leave, Natsume Shio stood up from the ground and looked at Naruto, who was standing unusually quiet among the crowd.

"Oh, here it comes!"

Hearing Natsume Shio calling him, Naruto immediately raised his head and wiped his sleepy eyes, looking like he had not woken up.

Seeing this scene, Natsume Shio couldn't help but have black lines in his head. He said, why is Naruto, who always likes liveliness, so quiet today? It turns out he is asleep.

"Wait, I want to challenge him!"

But just when Uzumaki Naruto was about to leave, Uchiha Sasuke suddenly made a voice and pointed at Naruto.
