Naruto opened the kaleidoscope because he was afraid of death

"Yo, it's quite lively." Uchiha Yu came out and greeted with a smile.

"Hey? Who is he, is he also from Konoha?" Naruto asked, pointing to Uchiha who suddenly appeared.

"You are the Naruto that Sasuke said." Uchiha said with a smile, but his eyes were fixed on Naruto's abdomen, and Naruto was furious.

Not only Naruto, but even the nine tails in Naruto's stomach also exploded, "Little devil, go, this man is very dangerous!"

Kyuubi has the ability to perceive good and evil. When Uchiha stared at Naruto, Kyuubi felt a strong malice, which made him feel even more disgusted than when Uchiha Madara controlled him back then. To be precise, it was fear!
"Hey? Who's talking?" Naruto was a little confused, because until now, he didn't know that there was a monster living in his body.

"Have you sensed it? But you can't escape, after all you all belong to Kaguya!" Uchiha said secretly, and then looked away.Only then did Nine Tails stop blowing hair, but he was still very vigilant.

Originally, Uchiha wanted to see Gaara, but was interrupted by Sasuke.

"O...Oni sauce."

Sasuke yelled, and quickly jumped down from the tree, and walked up to Uchiha Mu, blushing a little.

"O...Oni-chan?" Naruto and Sakura's eyes widened, their jaws almost dropped.

They remembered that Sasuke's brother didn't look like this, what happened?

"Everyone, I'm sorry, I have something to ask Sasuke, and I'll treat you to barbecue later." Uchiha Mu greeted and left with Sasuke.

Leave everyone with different thoughts.

Naruto: "Sasuke's older brother is much better than Sasuke, not like that stinky guy like Sasuke."

Sakura: "As expected of Sasuke's older brother, he is really handsome."

Temari: "Very nice man."

Gaara didn't think much about it, the person he was interested in left, and he didn't want to stay too long, so he left with Temari and Kankuro.

……

Uchiha first went back home to remove the shadow clone, and learned that Sasuke would spend several hours in the pupil space almost every day. Now he has mastered a lot of ninjutsu, but due to the problem of chakra, the staying power is not good enough.

Moreover, it has been two years, and there is only Ergouyu in Sharingan. Hmph, it seems that the stimulation is too little, so don't blame me!
So Uchiha took Sasuke to an open field in the mountains. "Sasuke, let me see your growth during this time!"

"Okay, brother, you have to be careful!"

Sasuke knew that Uchiha Mu was very strong, so he opened his Ergouyu Sharingan as soon as he came up.

"Huh? It's been two years, and I haven't arrived at Sangouyu Sharingan, Sasuke, you let me down!" Uchiha shook his head, showing a very disappointed look.

Sasuke couldn't bear this stimulation, attributes such as being arrogant and stubborn immediately came up.

"In the past two years, I have become a lot stronger. Don't lose just because you underestimated me!"

"Chidori!"

I saw Sasuke bowed his waist, grabbed the wrist of the other hand with one hand, and made a preparatory movement of Chidori, and then the thunder appeared suddenly, and Chidori sang together.

Thanks to Uchiha's help, Sasuke's overall quality is much higher than in the original book, so Kakashi gave him Chidori in advance.

"This is A-level ninjutsu, be careful!" (Chidori's advanced ninjutsu Raikiri is S-level)
After all, Sasuke, under the blessing of Chidori, doubled his speed, and suddenly appeared in front of Uchiha Yu.

However, Uchiha Mu didn't panic, and directly grabbed Sasuke's wrist with one hand, so that Sasuke couldn't get an inch in, and said in disgust, "Well, this can't be your full strength, it's really weak and pitiful!"

After finishing speaking, without waiting for Sasuke's reaction, he directly kicked Sasuke hard in the stomach.

Sasuke was kicked and flew out, and didn't stop until he hit a big tree.

"Ahem, damn it." Sasuke stood up in embarrassment, and wiped the blood from the corner of his mouth.

"Art fire escape ho fireball."

A fireball with a diameter of four to five meters spewed out from Sasuke's mouth, and the scorching breath approached Uchiha.

"The technique of water escape and water dragon bullet."

sizzle-

The water and fire collided, and a large amount of water vapor was formed immediately, covering the figures of the two people.

Sasuke looked around vigilantly, however, Uchiha Ou suddenly appeared behind Sasuke, but Sasuke didn't notice it.

"Don't expose your back to the enemy."

"Nani?" (o;
"Millennium Kill!"

puff--

Sasuke blushed slightly at first, as if enjoying it a bit, but the severe pain that followed made him take off on the spot! (Refer to Naruto's appearance when he was killed by the millennium. At first, his face was reddish. If you don't believe me, you can search it.)
Uchiha looked at Sasuke who was covering his butt and rolling all over the floor with satisfaction, and thought to himself: Now Sasuke and Naruto should be able to understand each other, after all, they have suffered the same pain, hehe.

"Brother...brother, you are too despicable." Sasuke stood up with difficulty and said.

As for Uchiha Mu, he changed from his previous kindness, and suddenly became serious, saying: "Sasuke, do you still think this is a game?"

"Huh?" Sasuke froze for a moment.

"Don't you want to avenge your parents with your own hands? How can you avenge yourself like this? How did you kill Itachi?"

Uchiha's words became more and more serious, and Sasuke was stunned for a moment.

"It seems that I have neglected my duty. I only wanted to take care of you, but I forgot to tell you how to become a real ninja!" After speaking, Uchiha Yu tied up Sasuke who was still in a daze with a rope, hung him on the tree, and took out a small leather whip in his hand.

Snapped--

A whip woke up Sasuke who was in a daze. Looking at Uchiha's current appearance, he said with some fear: "Brother...brother, what are you doing?"

Uchiha Mu snorted coldly, and said: "I was so gentle to you before that I made you forget your hatred and how to become a qualified ninja. Now, I'm going to wake you up!"

Snapped--

"Ahhh!"

As he said that, another whip was whipped, and Sasuke let out a painful wail.

Uchiha-san seemed to be addicted to smoking, with constant cracking noises, and at the same time he kept questioning Sasuke.

"Sasuke, tell me, do you still remember who your enemy is?"

Sasuke endured the severe pain and said, "Uchiha...Itachi!"

"Tell me, do you still remember the tragic death of your parents?"

"Remember...remember." Recalling the scene five years ago, Sasuke's hatred for Uchiha Itachi deepened.

"Then do you still remember the tragedy of the extermination of my whole clan? Do you know how many ignorant and ignorant children died under Itachi's butcher knife? Do you remember how many unarmed clansmen were slaughtered by Itachi like pigs? Do you remember the pride of our Uchiha clan?"

A series of questions made Sasuke's hatred for Itachi even more unforgettable!

"Answer me, do you remember?" Uchiha shouted while sobbing.

"Remember, I remember, how could I forget!" Sasuke also became emotional!

"Itachi Uchiha! I must kill you!"

After finishing speaking, Sasuke's Ergodama Sharingan began to spin crazily, and finally turned into a Sangoudama Sharingan!

Seeing this scene, Uchiha laughed heartily, "Silly boy, you got beaten up, and you still have to thank me in the end, I'm so bad! Hehe!"
