I can say this because for any jutsu there is a limit of how much chakra we can put in. Past a certain limit adding chakra will just waste it away. Of course the limit of chakra put in will depend on the jutsu. A C rank jutsu will have a limit lower than a S rank one.
That is why peple creates new jutsu, to be able to put as much chakra as they can and thus have more powerful techniques. But of course it is only for certain situations as in a fight it is not wise to put all your chakra in a single attack.
But this was not the best effect that it had. I had an enhancement on my WHOLE body. That is, also my eyes. Of course my eyes are not rinnegans already, that would be too easy, but instead of the remaining 19 years, it is now only a few. I cannot say how much is left, but at least less than nine.
I went outside with Mikoto to test my new powers. Outside there only was sand everywhere so I could go all out without worry. I still walked a bit away and punched as hard as I could on the ground.
Even though it was sand below, the strenght behind my punch was so great that an earthquake began. It was not a big one but still a earthquake. I could not really test my strenght well so I turned toward Mikoto who understand and made hand signs.
Three huge walls of earth appeared. I punched toward the first one and it immeddiately crumbled to little pieces. The force of the punch also sent many rocks toward the second gate and destroyed it as the rocks were flying too fast. But the third one did not got destroyed.
So now I had a great strenght and could quite easily destroy a defence, but if that defence was made with multiple layers then I would not be able to go past it with only one punch. I then began to ran as fast as I could and was now faster than before.
I went back toward where Mikoto was and activated Time slow. The time was still slowed by the same amount but it was now even less exhaustive on the body. And now that my body can endure more I can keep it for at least 8 hours without fighting. Of course if I make efforts it will go down by a huge amount.
If I cannot use the Susanoo and Time slow at the same time for long is because of the pain procured by the Susanoo that makes it impossible to keep it long. I used my other power by making a cut on my arm. I had a little trouble to slash my arm by using my weapon only because my skin and flesh got enhanced so I used mu wind coat.
It was more powerful than before and easily cut my flesh. I then waited for a minute and began using my power. I had to use a bit of energy but it was alright. I wanted to use my Susanoo but I decided against it as I knew that it went to the next stage and seeing how tall it was before, now people will see it from miles.
I decided to use my final power and fire appeared around me. But this was not a normal fire. It was purple fire. I could manipulate as much as I wanted. I made it go toward the sand and it got burned as soon as the fire touched the sand. This was incredible becasue sand was something very hard to burn.
I made it disapear and made hand signs.
"FIRE STYLE: GREAT FIRE BALL"
I made it toward the ground and what came out was a purple fireball a an unusually big size. It just went through the sand and went far in the ground. I looked down at the hole I made and saw that my fire ball went down the sand and even burned a lot of earth. It closed itself as it was sand around but I could now see the power of my technique.
The flames that I could manipulate were less powerful than the one made from the jutsu but they still had a lot of good points. First they were made of fire essence only so I could manipulate like they were another limb, so they were not like the ones made from jutsu that were made from the chakra.
The ones made from chakra could not be used without hand signs to guide the chakra so they had limited uses. That means that for a huge attack I will need to use a jutsu made flame, but if it is not the case then the essence flames were better.
But the biggest difference was that my chakra was already so concentrated that it could not improve again, where my natural flames will one day become stronger than the one made from chakra. After,this I also made a very good discovery.
That was that I could now transport the violet fire in my body. If I keep it in then it will help me improve my natural flame continuously without doing anything and I will not have to be afraid of this element saturation in my body because of the sage mode. But there was another interesting propriety from this fire, that is that it is able to restore itself from just an ember.
It will use the surronding fire essence and restore itself to it's previous stage. So I would keep some in my body and leave another part for the village. They won't all be able to use the fire sage mode as even if this flame helps it is still difficult and require talent to use the Fire sage mode.
If Mikoto could use it it is because she was an Uchiha and all Uchiha had an incredible affinity toward fire. But even for those who will not use it, just the presence of the fire will strenghten the bodies of the inhabitants of Konoha over the years.
