25 Creation of Rasengan

Two more months passed like this. My daily routine includes some early training with mother or father. Later during academy time, my shadow clone will substitute me. I will train with Team Minato sometimes as I grew stronger day by day.

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

My training with Team Minato yielded the most result. I was able to take Minato by surprise during our first bell test. But after he came to know of my jutsus and tricks, it got harder to take bells from him. He even further improved his Flying Thunder God technique as he added new jutsus to the 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 is at least better than that.

Minato taught me more jutsus of Fire, Lightning, and Wind Release, and I am grateful for that. My battle senses have improved a lot but all of this training was still under a safe environment. Minato won't deal a killing blow to us and we were aware of it which lowered our guard a little bit. In these two months, I have pretty much mastered all of the elemental techniques taught by Minato and now it is time to aim for the Space Techniques.

As usual, today I start to train in the forest near the Training Ground 3. Soon, Minato and his team appear with Kushina as we start our usual routine with another bell test. We fought with Minato for almost an hour. My teamwork with Team Minato had improved a lot, the only department I lack is Taijutsu and Senjutsu both of which require a strong body. Minato whopped our ass as we were unable to grab any bell.

Minato breathed heavily as he remarked,

"It is getting harder and harder to beat the combination of you four now. Ha… ha… all of you improved way too fast and I can't keep up. I will have to speed up the creation of my new jutsu."

'Oh! He has already started the creation of Rasengan. I can help him and in exchange ask him to teach me more about the space element. Minato was the only Shinobi before Otsutsuki's who had a profound knowledge of Space. Well, Tobirama Senju had enough knowledge to create the Flying Thunder God Technique. But it reached new heights under Minato's hand and Tobirama himself confirmed it.'

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

I inquired Minato. Minato nodded as he replied,

"It is still in development and isn't even a C-rank technique for now."

Minato stretches his right hand as he began to knead Chakra in his palm and began to gather it in one spot. The Chakra began to gather in his hand as it starts to form a sphere the size of a marble, but before it could expand further the Chakra explodes due to instability as Minato's hand got jerked back due to the recoil force of the Chakra and smoke rose from his palm guard. Minato sighs as he begins to explain,

"The principle behind this jutsu is to compress Chakra in a small sphere and then launch it towards the enemies as the compressed Chakra expands on contact with an enemy and explodes violently like a bomb. As you saw the recoil from the ball the size of marble was enough to almost break my hand. Now, imagine if it is the size of say a throwing ball; the impact caused by the explosion of such a ball would be ten to twenty times more powerful."

I pondered for a while as I thought about it,

'Should I tell him the complete training method of Rasengan or shall I just guide him in the correct direction.'

After contemplating for a while I decided to guide him,

'Minato is a genius, he will be able to figure the jutsu much earlier if I just guide him to correct direction. Also, I can't raise his suspicion by pulling out an A-rank technique without proper training out of nowhere.'

Minato looks at me as I am contemplating,

"I decided to create this jutsu when I saw a Tailed beast creating a massive orb of Chakra called Tailed Beast Bomb. The tailed beast Bomb had very high destructive power as it is able to obliterate a massive mountain to dust. I thought of mimicking that technique to create something similar that can be used by a Ninja to produce a similar effect albeit on a smaller scale."

I acted like I was thinking seriously over this matter but in reality, I am just thinking,

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

"Minato-san, I think your idea is great but you are moving in a completely wrong direction. You won't get anywhere if you continued like this."

Minato was perplexed by my claim. He had a pensive expression as he questions me,

"How so…? Do you have a better idea Izuna-Kun?"

I nod to Minato as I start to explain,

"Minato-san! There is a fundamental difference between the physique of the Tailed beast and the human body. I have read that Tailed Beasts are beings made up entirely of Chakra whereas we are made of flesh and bones. The tailed beast can collect and Chakra easily because their entire body is Chakra whereas in our body Chakra rotates in a pathway as it circulates inside the body. So, you can't do the same thing as the Tailed beast. If my hypothesis is correct then you should try to add rotation to the Chakra when you compress it."

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

A small chakra ball began to compress in his hand as the chakra rotated and stabilized the ball. The ball continued to expand till it reached the size of a tennis ball. Minato slammed the Chakra ball into a nearby tree as it created a small whirling hole the size of the ball before the Chakra faded away.

Minato became excited to see this as he begins to mumble,

"The stability of the Chakra is great but it lacks the power to do any lethal damage. I will continue improving it further."

He turns to me as he praises me,

"Izuna-Kun, you are very sharp and intelligent. You were able to improve the jutsu I struggled to create in past three months just by one observation. Tell me, which jutsu you want to learn next?"

"Minato-san. Can you teach me your space-time Ninjutsu 'Flying Thunder God'? I will also help you with your new jutsu."

Minato contemplated for a while before he replies,

"Izuna-kun! It is not that I can't teach you the jutsu. It is that learning this jutsu is very hard and not everyone is suitable for learning it. First and foremost, you must have some affinity for space elements to be able to read this jutsu. Second, you need to be a master in Fuinjutsu to be able to create your own seal to imprint space coordinates in it. Third, your body must be able strong enough to bear the stress caused by the sudden spatial shift. Fourth, there will be split second of vulnerability after the sudden shift."

He looks at me then continues,

"Although in your case we can ignore the fourth condition as you will eventually awaken Sharingan which will grant you incredible perception power. But still, with so many hurdles it is very difficult to learn this jutsu."

I begin to think of ways to convince Minato in teaching me the 'Flying Thunder God' Jutsu.

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

I wondered how the affinity for the space element can be tested. The Chakra paper has a limit and could only test the elemental and non-elemental type affinities.

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

Minato takes out a small scroll with a special seal with kanji word 'Space' on it. He hands over the scroll to me as he explains,

"This is a special Uzumaki Clan scroll. It is given to me by Kushina. When you infuse your Chakra in the scroll, the markings on the scroll will disappear and will reappear on a similar scroll to this one if you have the space affinity. Otherwise, you don't have space affinity."

Minato fishes out another similar scroll from his pocket and opens it. It is similar to the scroll in my hand but with no kanji word.

I begin to infuse Chakra in the scroll handed to me by Minato as I curiously wait for a response.

'Well, I have space element affinity so it wouldn't be hard for me to pass this test. Right!'
