Yoriichi P.O.V
-Next day-
Uzushiogakure training grounds
Today, dad is going to be teaching me ninjutsu.
Finally, I would be able to do the cool ninja things.
Dad entered the training ground and handed me a chakra paper and said "Let's find your chakra natures first."
Well ,I already knew my chakra natures but I wanted to see if I had earth and wind due to my mom genes and if I do I will be able to do ice release and crystal release.
I passed a little chakra through the leaf. The leaf was divided into 3 - one part was burnt, one wrinkled and the last one got wet. Looks like no kekkei genkai for me.
" Looks like you have three chakra natures which is extremely rare - water , fire and lightning. Why do you look upside though?" Dad asked
"I won't have earth and wind so I won't be able to use ice release and crystal release."
"Haha, you don't have to worry about that son. You don't need affinity for the element to perform Kekkei Genkai what's important is the genes and you have your mom's genes so you just have to master nature transformation and shape transformation of both wind release and earth release and and you might be able to perform ice release or crystal release or even both."
"Really?"
"Haha, yes but you can be as powerful as with two kekkei genkais with your 3 natural affinity elements too so let's focus on them. And don't get your hopes high there is a very little chance that you could do Crystal release or ice release."
"Alright so what element do you want to start with?"
"Fire style" I answered confidently, fire because well because spitting fireballs from your mouth is cool.
"Alright but before we can begin teaching you fire style jutsus.We will first work on chakra control."
With that dad walked to a tree and stood upside down on a branch.
"So first step is walking horizontally on the tree which I believe will be easy for you since you have already mastered that much chakra control with your sword techniques but standing and walking upside down on a branch will be more tough so we will start with that." Dad said
With that my hopes were dashed of spitting fireballs today but chakra control was good and necessary.
I walked on the tree horizontally easily but when I tried walking upside down on a branch I fell but I managed to land on my feet with a backflip.
I tried again and again for more than 50 times but without success.
Dad was having fun at my expense as I can see him trying to hold back his laughter
" Help me dad !!!" I said a little angrily.
"Well, it will come naturally to you. You are using too much chakra,you need to lower the amount.
This is one of the drawbacks of having too much chakra. But once you master chakra control, it will be very easy for you to do ninjutsu, Genjutsu, fuinjutsu and medical Ninjutsu."
I continued trying to climb the branch upside down.
After a week, I managed to finally climb the branch upside down. Then it was time to walk on water.
It took me another week to master it .And finally it was time to learn ninjutsu .
"So let's start with some basic ninjutsu."
"First up is Bunshin no Jutsu (clone technique), you would be able to form clones of yourself but they would be just an illusion. The next one is Kawarimi no Jutsu (substitution jutsu )which will help you switch places with a log or something similar and the last one is Henge no Jutsu( transformation jutsu )which will help you to take the appearance of whatever you choose."
Father showed me hand signs for these 3 jutsus. I followed them and mangad to perform each jutsu perfectly.
"See like I told you, after mastering chakra control it would be easy for you to learn ninjutsu."
"Now let's come to fire style jutsus. The first jutsus I will be teaching you is the traditional jutsu for uchiha clan which they use to teach their kids and members of the Uchiha clan are not considered adults until they've learned to perform this jutsu. The jutsu I am talking about is Katon: Gōkakyū no Jutsu (Fire style : Fire ball jutsu )."
"The hand signs for this jutsu are Snake → Ram → Monkey → Boar → Horse → Tiger ."
Dad was about to use his jutsu but then I interrupted him
"Dad but I only know the basic hand signs."
Dad was dumbfounded " I forgot you were just a 4 year old, with your strength no one would believe that hahahahaha."
After that for the next 2 hours, I learnt different hand signs. Some which I could remember, some not so much.
I tried performing the jutsu a few times but I failed. Dad gave me some tips after which I tried again.
After that I performed handsigns for the jutsu again slowly
Ram → Monkey → Boar → Horse → Tiger
I inhaled a breath
Katon: Gōkakyū no Jutsu (Fire style : Fire ball jutsu)
A medium to large size fireball came out of my mouth which was constantly increasing so I cut my chakra supply to it and it caused a good explosion.
Dad looked proud and said "Well don son, those Uchiha elders would be so jealous of your talent."
I smiled sheepishly hearing this .
I continued having lessons with my dad for the next 2 years.

Author Notes
Well I am doing these time skips so that when I make a mc fight a High rank Shinobi and manage to beat him y'all don't say he is just 4 years old. Lol
At 6 Kakashi became a chunin so I guess it should be a good age.
And he would not be fighting a high level shinobi in a serious battle anytime soon.
But there are always cannon fodder all of these things.
