I became Naruto Uzumaki's younger sister

Naruto excitedly went to find Sasuke, and sure enough he found him in the corner of the Uchiha training ground.

Among all the Uchiha children, Sasuke was the only one who didn't wear yellow clothes and didn't go to Uchiha Izumi's class.

There are many reasons, the two main reasons are that he doesn't want it and excludes himself from others. In addition, Sasuke is Itachi's younger brother, and other people are not willing to persuade and force too much.

Uchiha Izumi and Shisui tried to persuade him many times, but with little success. Sasuke began to isolate the entire Uchiha.

"Sasuke, I know how to use ninjutsu!" Naruto looked excited.

"Really!" Sasuke was also very happy. He had tried to teach Naruto before, but it was of no use. No matter how he taught him, Naruto couldn't learn it. Now his friend can learn ninjutsu and can accompany him. Go further.

In Sasuke's heart, he cannot become a strong man through physical skills alone.

Naruto nodded: "Jiraiya-sensei broke the seal for me so that my chakra can be more stable."

Sasuke frowned when he heard the seal. He had never heard Naruto talk about the seal before, and asked in confusion: "When were you sealed?"

Naruto shook his head. He had never considered this. When he knew that he could use ninja, he was very satisfied.

Seeing Naruto's confused look, Sasuke knew that he was unreliable and had to let himself investigate.

"Come and see the clone technique I performed!"

Naruto didn't think so much. He only knew that his sister didn't say anything, which meant there was no problem.

Naruto never considered whether Naruko knew that in his heart Naruko was omnipotent. He took him away from the malicious crowd, proved to everyone that he was a human and not a demon fox, and even asked Teacher Kai for help. Teach yourself physical skills and be at the top of your class.

Sasuke looked at the somewhat dazed clone and shook his head: "The purpose of the clone technique is to deceive the opponent. Who can you deceive?"

Naruto looked over and laughed, "Yes."

Then he released the clone and continued to form the seal: "Then I will practice more. If I can't do it 10 times, I will do it 100 times. If I can't do it 100 times, I will do it 1000 times until I can."

"Then prove it to me." Sasuke crossed his arms.

Naruto nodded.

Naruto spent the whole afternoon performing the clone technique, and by the end even Sasuke was amazed.

[Naruto also has too much chakra!

And he really stuck with it. ]

Sasuke has also experienced the feeling of constantly performing ninjutsu. In the end, the pain of chakra loss and the mental sting will be very uncomfortable, but the celebrity has been enduring these pains while performing.

[Naruto, I recognize you as my opponent. ]

"Sasuke, what do you think?" Naruto felt that the clone next to him was already very satisfactory to him.

Sasuke looked at the panting clone next to him and said noncommittally, "Go back and have a good rest. See you tomorrow."

Naruto returned home happily. His sister was not at home, making soup for Jiraiya-sensei.

So he lay on the bed after washing up. He had indeed consumed too much chakra today, and his mental state was also very bad.

Suddenly he fell into a deep dream.

The cold black passage, the muddy water underfoot, and a wave of malice came from the depths.

Naruto was a little at a loss, he didn't know where he was, but this real feeling didn't feel like a dream.

A huge attraction drove him to go deeper, and Naruto slowly moved in that direction.

When they reached the end, a huge black shadow exuding endless malice appeared in front of them. Fortunately, there was a huge cage that isolated the black shadow. The railings emitted a faint light. While shutting the figure inside, it slightly illuminated the black shadow. look.

"Are you a demon fox?"

Of course Naruto has heard others call him Demon Fox. He has read a lot of books and will not be as dull as the original. He just doesn't care and is not stupid.

Kyuubi had been in a deep sleep. He heard someone telling him to open his eyes and saw the little one in front of him. He judged at a glance that he was now sealed in his body.

"Kid!" Kyuubi roared angrily and wanted to stretch out his claws.

Naruto was frightened and fell to the ground.

"Let me kill you!" Kyuubi was now full of anger. Ever since he was sealed, Naruto had been locked in this darkness, and nothing else could be seen.

The claws stretched out from the gaps in the cage, and the wind they brought up even hit Naruto's face.

"Ah!" Naruto was so frightened that his face turned pale and he ran back.

He woke up from the bed while running, and unknowingly broke out in a cold sweat.

Naruto was a little scared, he felt that the rising malice would engulf and kill him.

As soon as you close your eyes, you will think of that image.

[Is this the demon fox sealed in my body? ]

Naruto could not imagine who could seal such a terrible thing inside his body, making him hate others.

Throughout the night, Naruto did not sleep soundly. Every time he fell asleep, he would return to the black passage and force his way out through willpower.

When the sun rose in the morning of the second day, Naruto still remembered the agreement with Sasuke, and dragged his exhausted body to the Uchiha training ground to find Sasuke.

"Sasuke." Naruto greeted weakly.

Sasuke was shocked when he saw Naruto's appearance. The dark circles and bloodshot eyes were too serious. He quickly came over to support the shaky Naruto's shoulders and asked with concern: "What's wrong with you?"

Naruto felt very sleepy, but he didn't feel safe: "I didn't sleep all night last night. As soon as I fell asleep, I would see the sealed demon fox."

Sasuke frowned. He went back to investigate yesterday. Naruto was called a demon fox by some stupid villagers, but he didn't know what a demon fox was, so he had no choice but to let the matter go. Today he heard what Naruto said, Plan to investigate to the end.

"Naruto." Sasuke shook Naruto, trying to wake him up.

Naruto raised his head, his drowsy look looked a bit cute in Sasuke's eyes.

Sasuke regained his composure: "Don't resist my illusion later."

"Huh?" Naruto didn't know the concept of genjutsu yet.

Sasuke has opened his Sharingan and cast his unskilled genjutsu: "Sharingan!"

Sasuke controlled chakra to invade Naruto's body. Naruto's consciousness was already overwhelmed and he fell into a drowsy sleep.

Naruto appeared in the dark passage again, but this time, there was someone beside him.

"Sasuke?!"

Naruto was very surprised: "Why are you here too?"

Sasuke pointed to his Sharingan and said a little arrogantly: "Of course it's because of my eyes."

"So you're here to help me solve my problem?"

Sasuke said confidently: "Of course! No matter what kind of demon fox it is, it will never bother you again."
