In Naruto as Ten Tail

In these five years, two years were spent on refining and solidifying the knowledge of intermediate seals.

They will be used as a foundation for advanced seals. It took me three years of trial and error just to barely qualify my skill as advanced.

I can slow time to 1:2 ratio for now. 1 year outside is 2 inside. Time is a very fragile concept, one cannot temper it without having enough power, only understand it.

I went and connected myself to the dimension and used its core as a base to set the array of seal lines and symbols to form a complicated web-like structure.

Once the seal was placed, the time seemed to slow down in the dimension but the person inside without enough understanding of time won't even notice it.

With this I can get more time. Let me see what's next. I scrolled through the system's screen thinking 'My Elemental resistance is lowest, let's make it go up.

What does it need? Let's use elementals to strengthen the body by using it on the surface and underneath.'

Using such methods may not be best in the long run, but for now it should be fine.

As I ran the fire element on the surface of my body and below the surface was the water element with my control I can use all elements at the same time regularly.

I used fire to burn and water to soothe but the effects were close to zero.

I increased the intensity and added lightning in the water to stimulate the body even further. 

Although our bodies are made of pure chakra it performs like a shell for us. My body was formed by it, Hagoromo even tried to stop it but to no avail.

when i was reborn in the 10th magatama. I only absorbed the core power of my being without the negative effects which 'he' helped me out with. 

Hagoromo wanted to destroy me at that time but I formed a connection with the rest due to me technically being their parent.

So due to not having all my energy as a foundation of my body , its formation was slowed down.

I can not go further than 10 tail power unless I involve myself or something.

What I need is to increase the durability of the shell, making it accustomed to the elements in large quantities to hurt it then heal it and then keep on repeating.

If I was human I would feel a lot of pain but since the body is just chakra no nerves for sensing pain or anything. 

Only thing that can make us feel pain is mental damage and affecting our chakra system.

When we are killed the chakra disperses and gathers to form a new shell.

The body itself would be weak and would need time to be at its peak strength.

As the elements on my body keep on damaging it, chakra heals the body. 

The process is very slow as the body needs time to be accustomed to every single element at a certain level. 

Using this technique again and again for the whole month is not an easy thing. It nearly bored me to death.

The intensity keeps on increasing as the time passes away and the whole month goes by. 

The body was getting sturdier and was able to nullify the damage to some extent but even after a whole month the level didn't  go which shows just how difficult increasing the level of this skill is.

I was getting bored so I made my clones find an effective method for this and went to do something else.

After sometime playing with my clones, games like tag, chess, wrestling all of this in full power without ocular powers as there would be no point in it otherwise.

Using full power to play like that was a good way to get a hang of your power and make myself accustomed to it, unlike those power driven people who just go and charge to the strongest person they find to test their power.

How idiotic a person could be, do you think that you could never die just because you got something to increase their power faster than others. 

They just kill them in the end by saying I am helping the people you will kill in the future.

How self-centered can a person be? Well they are only alive due to some omnipotent being (author) helping them from the shadows.

A whole week went by like this. I played chess with my clones using Transformation technique which I got from our one and only supplier.

'Now let's sleep, I have been training for 10 years and only slept for a total of a month. I need a month of sleep at least to have a healthy mind as I have 20 more years.' Thinking of this I went to sleep not before removing all the clones.

In a blink one and a half month went by  and I woke up ' looks like I was more tired than I thought. Let's take it slowly. I have all the time in the world. Not like I care about the world.

Even Madara and Hashirama have around 700 years to be born.

Uchiha and Senju clans will soon come into existence as those brats' descendants have scattered.'

Even Uzumaki will soon come to be.

I like Uzumaki's loyal character, they are just like asura. I have seen almost all of them care for their family and help each other. 

I never judge characters on the basis of anime. 

They never showed the full depths of a person's character unless they wanted to give them screen time, everything for the plot.

I can see everything I want to see while hiding in the dimension due to rinne-sharingan.

Even with all of that I won't save the clan.

Why would I, I don't have any connection to them. 

Nor do they have any use for me,  if things turn out to be good they will be saved without my help otherwise a certain Uzumaki will lose most of their power.

"Now let's go out and see what they are doing."
