BECOME MADARA'S GRANDLE IN NARUTO WORLD
CREATING RASENGAN

Two more months passed like this. My daily routine includes some initial training with mom or dad. Later during the academy time, my shadow clone will replace me. I will train with Team Minato sometimes because I grow stronger day by day. 

When the Minato team is on a mission, I will look for Uncle Sakumo who will train me in the techniques of kenjutsu and ninjutsu. In the evening, I will train with Kurenai in the Genjutsu technique.

My training with Team Minato yielded the most results. I was able to surprise Minato during our first bell test. But after he found out my jutsu and tricks, it became harder and harder to take the bells from him. He even further improved his Flying Thunder God technique as he added new jutsu to his technique. His new technique is called,

'Flying Thunder God - Second Step'

I thought the name was lame for such a cool technique, but then it reminded me of the technique used by Minato in the Third Shinobi War and thought it was at least better than that.

Minato taught me more Fire, Lightning, and Wind Element jutsu, and I am grateful for that. My battle sense has improved greatly but all of this training is still under a safe environment. Minato would not deliver a lethal blow to us and we were aware of it which slightly lowered our vigilance. In these two months, I had already mastered all the elemental techniques taught by Minato and it was time to aim for the Space Technique.

As usual, today I started training in the forest near Training Ground 3. Soon, Minato and his team show up with Kushina as we begin our usual routine with other bell tests. We fought with Minato for almost an hour. My teamwork with Tim Minato has improved greatly, my only shortcomings being Taijutsu and Senjutsu who both need a strong body. Minato hit our asses because we couldn't reach for any bell.

Minato let out a heavy sigh as he said, 

“It's getting harder to beat the combination of the four of you now. Ha.. ha. you all improved too quickly and I can't keep up. I have to speed up my new jutsu creation.”

'Oh! He has already started the creation of the Rasengan. I can help him and instead ask him to teach me more about the space element. Minato was the only Shinobi before Otsutsuki who had extraordinary knowledge of Space. Well, Tobirama Senju had enough knowledge to create the Flying Lightning God Technique. But it reached a new height under the hands of Minato and Tobirama himself justified it.'

"Minato-san, can you show me your new jutsu?"

I asked Minato. Minato nodded while answering,

“This is still in development and not even a C-rank technique for now.”

Minato stretched out his right hand as he started kneading the Chakra in his palm and started collecting it in one place. Chakras began to gather in his hand as it began to form a ball the size of a marble, but before it could develop further, the Chakra exploded due to instability as Minato's hand jolted backwards due to the chakra's retreat force and smoke soaring. from the protector of his palm. Minato sighed as he began to explain,

“The principle behind this jutsu is to compress the Chakra in a small ball and then launch it towards the enemy as the compressed Chakra expands upon coming into contact with the enemy and explodes violently like a bomb. When you see a backward blow from the ball, the size of the marbles is enough to almost break my hand. Now, imagine if the size was say throw ball; the impact caused by the explosion of such a ball would be ten to twenty times stronger.”

I thought for a moment while thinking about it, though,

'Should I tell him the complete Rasengan training method or should I guide him in the right direction.'

After pondering for a while, I decided to guide her,

'Minato is a genius, he will be able to know the jutsu early if I guide him in the right direction. Also, I was unable to raise his suspicions by issuing an A-rank technique without proper training out of nowhere.'

Minato looked at me as I pondered,

“I decided to make this jutsu when I saw the tailed beast create a huge ball of Chakra called the Tailed Beast Bomb. The tailed beast bomb had an extremely high destructive power as it was able to obliterate a huge mountain into dust. I was thinking of imitating that technique to create something similar that can be used by a Ninja to produce similar effects albeit on a smaller scale.”

I acted as if I was thinking about this matter seriously but in reality, I was just thinking,

'The time has come to ask Minato for Space element training.'

“Minato-san, I think your idea is good but you're moving in the wrong direction. You won't get anything if it continues like this.”

"How's…? Do you have a better idea Izuna-Kun?”

I nodded to Minato as I began to explain,

“Minato-san! There was a fundamental difference between the physique of a tailed monster and the human body. I have read that the Tailed Monster is a being made entirely of Chakra whereas we are made of flesh and bones. Tailed Beasts can collect and chakra easily because their entire body is Chakra whereas in our body the chakra rotates in its path as it circulates within the body. So, you can't do the same thing as a tailed monster. If my hypothesis is correct then you should try adding rotation to the Chakra as you compress it.”

Minato was surprised by this revelation as he immediately tried to suppress the Chakra while adding rotation.

A small chakra ball begins to press in his hand as the chakra rotates and stabilizes the ball. The ball continues to expand until it reaches the size of a tennis ball. Minato slammed the Chakra ball into a nearby tree as it created a small, spherical rotating hole before the Chakra faded.

Minato became excited to see this as he started muttering,

“Chakra stability is great but it lacks the power to do lethal damage. I will continue to improve it further.”

He looked at me as he praised me,

“Izuna-Kun, you are very sharp and intelligent. You can improve the jutsu I tried to make in the last three months with just one observation. Tell me, which jutsu do you want to learn next?”

“Minato-san's chat. Can you teach me your space-time Ninjutsu 'Flying Lightning God'? I'll also help you with your new jutsu.”

Minato pondered for a moment before he replied,

“Izuna-kun! It's not like I can't teach you jutsu. Because learning this jutsu is very difficult and not everyone is suitable to learn it. First and foremost, you must have some affinity for the space element to be able to read this jutsu. Second, you must become a Fuinjutsu master to be able to create your own seal to print the coordinates of the space inside. Third, your body must be strong enough to withstand the stress caused by sudden spatial changes. Fourth, there will be a split second of vulnerability after a sudden shift.”

He looked at me and continued,

“Although in your case, we can ignore the fourth condition because you will eventually awaken the Sharingan which will give you tremendous power of perception. But still, with so many obstacles, it is very difficult to learn this jutsu.”

I began to think of a way to convince Minato to teach me the Jutsu 'Flying Lightning God'.

“Minato-san, how will you test my affinity with the space element.”

I wonder how the affinity for space elements can be tested. Chakra paper has limits and can only test the affinity of elemental and non-elemental types.

"Oh! If you want to learn my 'Flying Thunder God' jutsu, then I'll test your space affinity. ”

Minato took out a small scroll with a special seal with the kanji word 'Space' on it. He handed the scroll to me as he explained,

“This is a special scroll of the Uzumaki Clan. It was given to me by Kushina. When you insert your Chakra into the scroll, the mark on the scroll will disappear and will reappear on a scroll similar to this one if you have a space affinity. Otherwise, you do not have space affinity.”

Minato took out another similar scroll from his pocket and opened it. This is similar to the scroll in my hand but without the word kanji.

I started inserting Chakra into the scroll handed to me by Minato as I curiously waited for a response. 

'Well, I have the affinity of the space element so it won't be difficult for me to pass this test. Aye!'
