Three Years Old

At first, they refused, but when they saw how boring I was to always do the same, they began to "play" with me when in fact they began to promote the training that was already registered in the documents of my clan that my mother had ready to use as a guide for my upbringing.

The training started when I was two years old, the training sessions were to take advantage of my flexibility with physical stretching.

These pieces of training were simple and basic with the intention of not hurting the children who perform these exercises, whether or not they have a chakra within them to be able to support the training.

The chakra worked as a medicine that encouraged my muscles to strengthen, this effect was also shown throughout my body, while at the same time my chakra grew in quantity by having a better physical state, I already had the soul, I just lacked having a body that would support my soul and come to have a harmony between the two, but since I am part of the Senju clan, that problem was solved by the nature of my clan for having great reserves of the Yang element that would be as vitality, which caused that from a child, I had more chakra than other children of other clans in the opinion of the Anbu.

When I was three years old, there were only two Anbu left protecting me, they maintained my training routine during that time, all under the orders of the Hokage, apart from the two of them taking turns looking after me, while serving under the Hokage directly awaiting some mission.

Since I was three years old, I showed a bit of my intelligence by not behaving like any normal child, something that was accepted as something very normal, well... it was common for children of ninjas to behave in a more intelligent or special way, a proof of this were; Kakashi, Itachi, Madara and almost the entire Nara clan.

In this ninja world, it was not a surprise that a four-year-old was as intelligent as a 10-year-old, the difference was only in how much emotional control they had and how much knowledge they had.

But all those children behaved like a child alone in front of their parents, something that I did not have and marked from the beginning, by not calling anyone dad or mom, always calling the others by their names or adding san, maybe no one questioned me for my parents something that made my life easier by not having to pretend to want to have some, when I don't know if I could accept them since I still can't forget my other family that I left behind.

At this moment I find myself using my chakra for the first time to be able to keep a tree leaf on my forehead and to my joy, it was very difficult.

"Don't be discouraged, I know you will do it" Sora-neesan told me as soon as she saw that the leaf fell from my forehead, but she was confused when she didn't see me depressed.

And why would I be?

Not being able to control my chakra is a sign of two things, that the chakra cannot leave my body like Rock Lee's disease or that I have so much chakra that I cannot control it and obviously it is the last one, since I could hold the leaf for two seconds and Anbu have affirmed this fact.

"The boy is not discouraged, because he understands that he has a lot of chakra" Inu-nisan's voice came from a tree and what he said is true, since he told me in one of the talks we usually have that I have a lot of chakra.

I just nodded as I picked up the leaf again to try to master my chakra again.

It was a strange feeling to feel my chakra, it was like warm water running through my body and once I realized it, I could not stop feeling it, all because I have 20 years of life where I had no chakra inside me, which caused the chakra inside my body to come out like a lighted spotlight in a dark room.

Ignoring it became impossible, excited to take the first step to be a ninja, I started trying to master my wild chakra.

First it was to put a leaf on my forehead, then I was to add more leaves in different places, one at a time, forehead, shoulders, elbows, hands, stomach, knees, and feet.

The farther from the forehead the more difficult it was to control my chakra, the mastering of this exercise took me half a month of hard effort every day in all my free time.

During all that time I never managed to exhaust my chakra since the consumption was very small, so I switched to holding rocks in my hands with only my chakra, something that came in the guide that I was following as part of my training.

They were flat rocks to make chakra training easy which became control and wear, and tear as holding the rock with chakra consumed enough chakra, and if I exercised too much chakra I would waste chakra unnecessarily so I need good control to regulate my chakra and last as long as possible.

This training was also physical as I had to have the riding position while holding both stones with my arms outstretched.

It was fucking difficult the routine I have, but knowing that my life depends on what I'm doing and having the second shinobi war happening as motivation, made it easier for me to continue with my infernal training.

"He is a boy with a strong will, he continues the exercises, although he doesn't like it and keeps the rhythm better than we had calculated" An Anbu with a dog mask found himself kneeling in front of the third Hokage [Hiruzen Sarutobi].

The Anbu was giving his weekly [Yuki Senju]'s report to the Hokage as requested after learning that Yuki's mother had planned to use Tobirama Senju's journal to train her son.

The diary was a copy of the original and only contained Tobirama Senju's training routines, some were simple ideas that came up when he created the Ninja Academy or that he did as a child, but that training was hell since it required a lot of Will to will be capable to do it, something that young children would not have unless they were born in a situation that forced them to have a great will like the case of Might Duy who cannot use chakra or the same Tobirama that was born in times of war and death.

Hiruzen was completely surprised that Yuki kept the rhythm with the training without complaining or slowing down, on the contrary, when he reached the chakra training phase it was when he had the most advancement.

Yuki showed great talent and dedication in chakra training, but he did not slow down with his physical training.

"Still watching and protecting him, he's still too young to have all those old men brainwashing him just to get him to marry someone from their clans." Hiruzen turned a little sulky when he remembered one of his Anbu's report of the plans, from some clans to try to get Yuki to marry someone from their clan to strengthen their clan by gaining the wealth of the Senju clan and improving their blood lineages by gaining the strong vitality of the Senju.

"He is a genius... but there is still a long time to show if he will be someone who survives and shows his talent or dies trying like many others" Hiruzen clenched his fist when he remembered many ninjas who were promising, but because of the war died before they could spread their wings.
