In Naruto Universe, time travel to become Naruto's sister

It's like getting up early every day in Green Pool.The combination of her bloodline and the chakra of the Nine Lamas greatly reduces her need for sleep, allowing her to sleep for only about 4 hours, although the time is short, Green Pool can still get a good rest.

Every morning, she strictly follows her training plan.She floods her entire body with chakra, stimulating every muscle in her body while strictly controlling every bit of chakra in her body.This is very crazy, a bad one may explode and die, but it is very useful, it can train her control over chakra well, and it can also train her body.

An hour later, her whole body was drenched in sweat, she stopped exercising, and turned to meditating to increase her aura.If a normal 3 year old did this every morning, she probably wouldn't survive a minor, but how can Green Pool be considered a normal 3 year old?She has perfect control over every aspect of her body.She has hundreds of thousands of years of experience in exercising her body.She clearly knows how strong she can increase her strength without causing any permanent damage to herself.

"Well, it's time to buy us an apartment. How about going to the library first to learn more about the village. I also need to do some research on the best way to make money right now.

Just when Green Pool finished sorting out her thoughts, Naruto walked into the room sleepily.

"Good morning, sister."

"Oh. Good morning, Naruto. Ready to learn your first jutsu?"

This instantly woke him up.

"Yes, yes, yes. Tell me how to be sis. Sister"

Just when Green Pool was about to start explaining, someone knocked on the door.

"That should be breakfast. Let's eat, and then we can start."

Lvchi quickly turned into a human form and opened the door to take the breakfast.After breakfast, Naruto couldn't wait to learn his first ninjutsu, so Midorike quickly started explaining how it was done.Unfortunately, a big problem arose.

"Sister, what is Chakra?"

"Damn, I forgot about it. I don't think this explanation will help Naruto much. Maybe I can inject a little chakra into Naruto so he can understand what that feels like?"

【By the way, didn't you say that he started training at the age of five? 】

"Oh my God, Nine Lamas, you care about another human being. It's incredible, I'm so proud of you for taking that step."

[grunts]
"Here, can we stop doing this, is it interesting to pretend to be sleeping, the screen is full of embarrassment,"

As for Naruto's training: I decided to at least start teaching him something to improve his chakra control.If I were to start teaching him when he was 5 years old, it would take a lot of work to get to a level that I think is right.

[Didn't you say that your method is too complicated? 】

"Yeah, so I hope to come up with some simple methods, which are more suitable for Naruto's cultivation."

"Okay Naruto, close your eyes and try to feel something moving inside you. I'll inject a little bit of my chakra near your belly. Try to focus on that spot."

It took some time, but after about an hour, Naruto managed to feel his own chakra.

"As expected of my younger brother, he is a genius."

[You don’t even know whether it’s fast or slow and you exaggerate, Fudimo is too obvious]
"No, I know, because my brother is the standard answer, to be precise, the perfect answer."

[...]
"Well done, Naruto. Learning how to create and control your chakra is the first step to becoming a ninja. Do you want to try shapeshifting now? Remember, inject chakra into your mudra and imagine what you want to become."

"Okay, sister, I can do it!"

Naruto slowly started going through the correct mudra, and then began to infuse his chakra into it.When Naruto tried to inject it into his hands, a large amount of chakra began to leak out.

"This chakra is fifty times more than needed."

[Not surprising.Still just a drop in the bucket for my chakra. ]
"Indeed. Given the amount of chakra, Naruto might have a hard time learning to use this jutsu effectively."

A few seconds later, a cloud of smoke appears, then disappears, revealing that Naruto has become... something.

Somehow, it can be considered what humans look like.Well, it has at least 4 limbs and a head, however, the proportions are very inappropriate.The upper arms are noticeably larger than the other two.Yes, there are other "two".One of its legs somehow turned into an arm, and that face looked like a random template chosen during character creation.

Naruto quickly noticed that something felt wrong and canceled the transformation.He was momentarily disappointed at what he hadn't done well, but those thoughts quickly stopped when he heard Green Pool's laughter.

"What, you think you can do it with just one try? This is one of the ninjutsu you need to master to graduate from ninja school. You can already transform, which is not bad. Now you just need to try hard to imagine what you want to become. I suggest you start by changing small parts of your body first, and then try to completely transform."

Naruto couldn't help but blush a little, after all he really thought he could get it done on the first try.However, when Green Pool started to praise him and give her a happy smile, he quickly recovered, but then he realized that something seemed wrong.After thinking for a while, he realized what the problem was.

"Sister, you said that this is something that ninjas need to master when they graduate, but you can do it perfectly."

"Haha, that's because your sister is a genius."

【You are really shameless. 】

"What else do I have to tell him? One day I might tell him about my past life, but certainly not when he's only 3 years old."

[Anyway, for whatever reason, I still think you're shameless. ]
"Okay, but it's true, I can't deny it."

"Awesome! My sister is a genius"

' Sigh my cute little Naruto is so pure.I need to make sure he's not tainted by society.

【Aren't you the biggest source of pollution? 】

"Shut up, stupid fox. No one will think you are dumb if you don't talk."

[Oh, mad because you know I'm right? ]
"I'm not angry."

"Naruto, there is a good training method that will make it easier for you to learn ninjutsu in the future. Are you interested?"

How could he not be interested?He began to nod eagerly.

"Of course I want to know. Teach me, teach me!"

Green Pool quickly prepared an empty bowl and filled it with water.This is the chakra control exercise she came up with.

"Okay, Naruto. Here's what you have to do: I want you to cover one of your fingers with your chakra and then submerge it in water. Your goal is to protect your finger from getting wet while creating as few ripples as possible."
Green Pool quickly put some chakra into his finger, and then submerged it in water.After stirring the water for a few seconds, she withdrew her finger and placed it on a nearby piece of paper to show that it was indeed not wet.

"After you've learned how to do it, add more fingers until you can do it with your whole hand, and sooner or later you can do something like this."

This time Midorichi wrapped her whole hand in chakra and put it back in the water.This time, however, she grabbed the water and took a big bubble from the bowl.Hold it in your hand like a water polo.

"Cool isn't it?"

"It's amazing! So, as long as I practice like this, I can form such a water polo?"

"That's right. It won't be easy, though, and don't be discouraged if you can't do it quickly."

"Haha, okay, I'll go right away."

"How do you get a young child through a boring sport? Show him some fun things he can do."

[Are you a devil?He is still a child]

"Isn't it very interesting, Mr. Nine-Tailed Demon Fox, and please correct me, that is, I am also a child."

"I'll be out for a while Naruto, I have some things to do, I'll be back for dinner."

Naruto just nodded absently, trying to concentrate on applying chakra to his fingers.

"Well, we have to solve the problem of survival first, and then we can consider other things."
