Yes, I forgot how to use substitution jutsu in the story. I'm just going to make naruto train correctly on how to use it. I did some research and basically it is an illusion but just like in Shinobi striker, it will teleport him somewhere random kind of. Update: Wednesday October 19, I forgot about this story completely as I was completely busy with stuff (school too) I will try to be more consistent and upload more often. The time I'm updating this chapter is on a school day at 2:17 AM so I'm lacking sleep.

Skip the introduction

Just as naruto and kakashi made it to the training grounds, might guy noticed them both and stopped his training to greet them.

Guy: Kakashi! My eternal rival, are you here to train with me?!

Kakashi: No unfortunately 'fortunately' but I got someone who was looking for you to train with though.

Guy: who is the little guy?

(Guy would probably never say this but don't tell him or he'll probably narrate the story in which I don't want.)

Kakashi: This is naruto, he wants to train with you and possibly learn the 8 gates.

Kakashi: but before he does that I want to teach him something.

Naruto is confused on what kakashi wants to teach him and kakashi motions him to do a offensive jutsu in which naruto does hesitantly.

When the jutsu hits kakashi, naruto is faking his worry as he knows kakashi is alive. After the smoke clears, all naruto sees is a log in his place as he starts to wonder why his substitution jutsu doesn't do that.

Naruto: 'wait if he used the substitution jutsu then why is mine almost completely different?'

Kakashi: Yo naruto, look behind.

Naruto looks behind him only to see kakashi there.

Naruto: How'd you do that?

Kakashi: It's called the substitution jutsu naruto. Try doing it when I do the fire ball okay?

Naruto: okay!

They separate about 50 feet and kakashi does the fire ball jutsu and as it's about to hit naruto, he substitutes but for some reason there is nothing in his original spot.

This very much shocks kakashi who starts to walk to naruto to see if he knows anything about it.

Kakashi: How did you do the substitution jutsu but leave nothing in your previous spot?

Naruto: I honestly don't know, it's been happening ever since I learned it.

Kakashi: that's quite interesting, maybe we can call this a modified substitution jutsu? It could be surely helpful to think you're body got evaporated by fire or any other jutsu.

Naruto: It's really that good?! ( Naruto has stars in his eyes)

Kakashi: Yes, now let me and guy train you with all kinds of 'cool' jutsu's and training styles.

Naruto: Okay!

They begin to train and let's just say that naruto impressed kakashi with his skills and stuff, and kakashi was also shocked but kept it hidden very well when naruto did the fire ball jutsu.

Naruto is still getting absolutely whooped by kakashi and I don't mean it figuratively. He is basically getting mopped like team 7 did during the exam with kakashi to get the bells.

After a while, naruto rested up and went up against guy for training and he got whooped too. But he is improving fast thanks to his system.

They then do jutsu training in which he has to try to overpower kakashi's jutsu which leads to naruto getting his overpowered every time.

Naruto is getting both frustrated and happy at the same time because he keeps getting his butt kicked but he's also leveling up his skills and adding to his stats.

(I'm going to introduce more cursing as this fanfiction goes on but cursing will remain at a low level. I dont curse irl tho)

As naruto gets beat, he wonders something and asks kakashi a question.

Naruto: Ka-Ka sensei, what's fuinjutsu?

Kakashi then has a dark look on his face as he hears the nickname but when he hears fuinjutsu, he is a bit shocked.

Kakashi: where did you learn this naruto?

Naruto: When I snuck around the village I heard some whispers and went to check. I heard something called fuinjutsu. 'Gotta lie'

Kakashi: Alright naruto, let me explain about fuinjutsu because my sensei taught me a little about it.

Kakashi then explains what fuinjutsu is to naruto and a little about how it works and how to study it. He then disappears and reappears holding a book about fuinjutsu.

Kakashi then hands the book to naruto and he tells naruto to study it and learn about it.

A cliffhanger again, I'll upload the next chapter tomorrow if I don't forgot and if im not lazy.
