Training, training, and even more training

[Kei Uzumaki's POV]

I was thoroughly reading a book about Fuinjutsu and all of its applications. I also had the stationary required for learning it near me. Fuinjutsu was known to be the most challenging art to learn to use due to the requirements it held. Something emphasised to me in this book.

The reason was unadorned. Only those with high intelligence could do anything with the art of seals.

One, it required the ability to comprehend what one was doing. Why? Because Fuinjutsu happened to be all about scientific mathematical formulae. It was similar to high-level calculus all in order to set parameters on the fuinjutsu. The kanji used is typically a sequence that the parameters follow.

In order to use Fuinjutsu techniques that don't require ink and paper, one requires to do all these calculations mid technique.

Though that wasn't the only thing as a single mistake with the brush whilst creating the seal could be dangerous.

Chakra is also an indispensable prerequisite to activate a seal completely.

It's the reason why the original summoned me. To gain knowledge over the recherché art of Fuinjutsu.

I had been reading about storage seals and explosion tags.

The types of equations required for explosive tags are principally composed of E=MC² equations. One manages mass and quantity of chakra whilst another handles the speed of it. Then, the force of explosion is the energy part of this calculation.

To create a storage seal, one has to use inflationary theory in order to create an otherwise small pocket dimension.

Needless to say, Fuinjutsu was complicated and required a special mind to understand it and use it fully.

Inside training ground 15. I held a rectangular chakra construct as I had been practising shape transformation with an exercise I myself created.

This exercise is referred to as chakra shapes.

This exercise is about taking one's chakra from their body in the shape of your choosing. Then you most change the shape to another constantly

Then, the next step is changing the density and size of the technique.

BTW, the Rasengan spins as well, so creating a sphere out of chakra does nothing except imitate it.

I increased the density of my chakra. Then, I changed its shape as well. I used my free hand to wipe a bead of sweat off my forehead.

I started to alter the size of the shaped chakra to be about 30 centremetres in diameter. As the ball condensed to be about 15 centremetres.

I stopped the exercise as I had run low on chakra with the exertion evident by the pool of sweat dripping to the floor.

Right time to dispel myself.

A leaf burned in my hand as I quickly applied water chakra to put the flames out. Why was I training nature transformation for an element not of my affinities? Kit versatility.

It is often noted that the more skills one possesses, the more likely one is to be employed. I took this concept and applied it to a war ridden world. The more tools one has at their disposal, the greater the chance of survival.

I gripped another leaf as I began to dry the leaf of its water, turning the leaf brown in the process. It died afterwards but soon regained life after I fed it by channelling the water through the leaf.

Then, the leaf crinkled as I generated lightning chakra into it. Afterwards, I utilised earth natured chakra to make it turn to mud.

It fell to the floor as I prepared for the harder part. Creating a stabilised form of the element that also trains shape transformation.

Starting from lightning, I channelled the  electrical current to my hands as I created a ball of lightning. I kept it there as the elemental ball started to destabilise. I continued to manipulate my chakra as I focused on restabling the ball of lightning.

The lightning equiliberated slowly as the ball became calmer and more subdued as I focused.

As the minute passed, I couldn't help but wonder what the original me was doing.

I used my right arm to do a one-handed pushup without my feet on the floor. In fact, I was doing a headstand push-up.

Up, down, up, down, up, down. I constantly and repetitiously repeated the motion. Seeing my face move closer towards the grassy floor and away from it. 

I stopped doing it as I inevitably finished my thousendth push-up. The soles of my feet touched solid ground from within my sandals.

I suddenly gained the memory of one of my clones dispelling. This one was training shape transformation with the chakra shapes method.

I felt something akin to anticipation as I couldn't help but like the idea that I was advancing quickly.

Those were my thoughts as I approached a notebook, and within it were the contents of my own personal Jutsu. One that was still being developed.
