The Uchiha - Senju Immortal

In less than half an hour, I was able to walk on trees or walls without any problem, just like walking normally, when my father came back and learned that I already mastered these, he was utterly shocked and examined my body ''You... you are a Sage Body!''

This time I got surprised, I thought that the knowledge about Sage Bodies wasn't known before Hashirama appeared, well, not that you can blame me since there isn't much about the Warring States, haha.

Shocked like that, my father quickly brought many different kinds of ninjutsu after he saw that my control over chakra is already that good, he probably wants me to be strong enough to protect myself earlier, I'll also start training my Taijutsu, Senju Clan don't have good Genjutsus techniques so I can't train it yet but at least these two I can.

There was one ninjutsu for each element - Suiton: Water Bullets, Katon: Flamethrower - Raiton: Thunder Ball - Doton: Earth Wall - Futon: Great Breakthrough, as for Yin-Yang, there wasn't any but anyway, I thought some of these weren't available at the Warring States, I'm honestly surprised.

I started to practice Water Bullets first and I wasn't able to use it on the first try perfectly, the reason of it is that my chakra control isn't good enough to use it perfectly, I missed some targets, meditating while analyzing why I failed, I took a deep breath before muttering and doing hand sings ''Suiton: Water Bullets''

Small balls of water were sent forward towards different targets before piercing it perfectly, seeing that I mastered it easily, I went for the next one, Doton: Earth Wall and it was actually very easy, the chakra control required was much less, after feeling satisfied, I started to practice the Katon: Flamethrower and it was more difficult than Water Bullets, it took me a few tries before making a good one, comparing, my chakra reserves are higher than a normal genin, this just because I only started to refine chakra.

A normal genin wouldn't be able to use this many jutsus without using all of their chakras, anyway, after half a hours practicing these three jutsus to make it perfect, I went for both Futon: Great Breakthrough and Raiton: Thunder Ball, the first was actually difficult but with the experience of Flamethrower, I was somewhat familiar, Thunder Ball was very easy and I was able to do it on the first try.

However, I'm feeling strange, I mean, very strange, like there's something trying to get out of me, this feeling is familiar but strange at the same time... yes, now that I think about it, it's the same feeling I got when I was on the voice, space!

It feels as if I can.... manipulate it freely, trying a few times, I failed miserably manner but I felt as if I'm just about to succeed so I kept trying for one, two, three, four and five hours, I was about to give up and tried the last time and suddenly, a small 'space opening' like the ones Kaguya did on the anime appeared in front of me, it was too small and even a 4-years old kid like me isn't able to enter, however, I indeed succeeded!

Haha, I also guessed the reason I couldn't make a bigger one, it's simply because of my chakra reserves aren't high, if I were to compare my own chakra reserve to the Great Villages ranking, it's only comparable to a Chuunin, anyway, my hand and arm was able to pass through it so I decided to test something, throwing a kunai randomly, I opened a small space where I threw it and then another one behind a target, the kunai appeared from the space opened behind the target and hit it successfully!

I'm able to open small spaces like this without caring about ending my chakra reserves drying up for about 10 minutes, which is more than enough to kill enemies, in my previous life, which is more than a few million years ago, I was the greatest scientist, doctor, etc, from the world and as a doctor, I naturally saw people dying, thousands over the years, I also used to be a doctor in battlefields that happened in small countries where certain countries were battling each other for resources, I also was forced to kill sometimes and I simply became dull to it.

Absolutely, I'm certainly not a good person and I did many things for my own d.e.s.i.r.e of having the Perfect Body, the current era that will last for a few decades will force me to kill, I won't kill anyone from Uchiha unless I'm without any way to avoid doing so, my mother is an Uchiha, after all.

Maybe my existence can finally make peace between them, haha. My thoughts were interrupted as my father entered the courtyard and talked in a rare happy tone ''Son, big brother wife's pregnant, I'll be uncle and you will be the child cousin, haha!''

''Really?! That's amazing, father!'' I said, I'm kinda excited to see my cousin, the future 'God of Shinobi' being born, however, I still need to start my training, my chakra control is considered good and all I need is new ninjutsus to train and get stronger, my taijutsu is still lacking very much

''Father, I want to start training my taijutsu!'' With determination in my eyes, I said to my father and for some reason, his smile felt awkwardly evil as he said ''I will make your training like hell, hahaha'' while laughing loudly.

I didn't get scared because after millions of years in the void, alone, if you don't get insane, you will surely have a strong 'Will', unbreakable, by the way, I'm probably immune to any kind of Genjutsu except Infinite Tsukuyomi, I'm not sure of its extent, after all.

''Bring it on!'' I yelled as my father started my training.
