The Uchiha - Senju Immortal

In the blink of an eye, eight years passed, on these eight years, both Senju and Uchiha Clan not only managed to get stronger but also expanded their influence because of their neutral status, even the old grudges between the clans slowly decreased, it seems that they finally realized that hate only generate more hate.

I also accompanied little Madara, Izuna, and the four Senju siblings growth, all of them seeing me as a big brother figure, despite the peace, I taught them that peace is always temporary and there'll always be someone with a bad mind trying to disrupt it, by the someone I mean Black Zetsu, by the way, Tobirama isn't an Uchiha hater anymore though he doesn't know I'm from the Uchiha Clan too.

Judging by this timeline, little Hashirama and Madara must be meeting right now, maybe I should use 'Transformation Jutsu' and fake a sneak attack on them? On these eight years that passed, I fully mastered not only the Gravity Seal that can now be used together with my Taijutsu but also many different minor Sealing Techniques.

Nodding to myself, a puff of smoke was heard as without hand signs, I transformed into an older version of myself but with red-colored hair, oh, I forgot to mention but I grew quite a bit, I'm now 1,65 meters tall, I also let my hair grow a bit. [A/N: Shiro current appearance is on the cover, just changed it, xd]

These years that passed, my eyes evolved from two-tomoes to three-tomoes, unfortunately, it didn't evolve to Mangekyou Sharingan but I believe it won't take too much time, I'm not really worried, with more than 70 years, it's quite possible that my eyes would have already evolved to Rinnegan when the Shippuden starts, even before it.

I picked a black outfit and a white mask before going to the familiar mountain that the two little brats were talking happily with each other, even fighting to get stronger, both of them are extreme genius, no, monsters and except for me, there's no one that can even defeat them at the same age of them except themselves, which is also one of the reasons they became best friends and rivals.

They share the same view of peace and with the idea that peace is really possible, as shown by the current Uchiha, Senju, Uzumaki and even the Hyuuga Clan, they achieved peace, more and more small clans are also adopting this style of being Neutral, most of them don't like war, in fact, no one like war.

My strength also advanced to A+ peak, from now on I'll just use the village rankings, basically, I'm now at the peak that an Elite Jounin can be, I'm on a bottleneck, anyway, I have plenty of time to get stronger, by the way, the difference between a Jounin and Elite Jounin is incredibly high, if before I could hardly open a portal to fit me and go back to the clan at the cost of exhausting myself, I can now do it while using a third of my chakra.

The 'Space Manipulation' isn't just opening portals, I literally can control it, it was just the easiest way I used to train my own control over it, after my control over it was perfect, I started to feel the spatial fluctuations and in two years, I learned how to teleport over small distances, on the start, I was able to teleport over only five meters but as the years passed, I can now freely teleport through 15 meters of distance, I can teleport more than that but the stain on my chakra would increase enormously.

If it's only 15 meters or less, the stain over my chakra is incredibly small but if it's more than that, my chakra would be exhausted easily, opening a portal and teleporting is completely different, I need precise control of my Space Manipulation and the spatial fluctuations, anyway, I got distracted on these thoughts but I already arrived on the mountain, where I silently observed little Hashirama and Madara.

They were talking happily before I suddenly appeared in front of you, Madara was the first to react as he said ''Who are you? What's your purpose?!''

''Who I am doesn't matter, you just need to know that today is your death, brats!'' I said while faking an evil laugh and tone.

Hashirama also reacted and said ''Hehe, we just need to beat the crap out of you!'' before both of them did hand signs, Madara shouted ''Katon: Great Fireball no Jutsu!'' as a huge fireball came towards me, before it could collide with me, Hashirama also shouted ''Futon: Breakthrough!''

A gust of wind went towards the huge fireball and merged before the fireball suddenly doubled in size, a good combination, indeed, however, this won't work on me, I said in a low voice ''Suiton: Great Waterfall!''

Water appeared out of nowhere and engulfed the Great Fireball as both jutsus nullified each other, a stream of smoke rose, intercepting everyone view but I could still sense their chakra, I dashed towards Hashirama first and with the back of my sword, I knocked him out as the stream of smoke slowly dissipated under Madara use of Futon.

Smiling slightly, I said ''I have your friend with me, I'll give you a choice, I'll let you live if you go away, he's my objective, after all..''

My intention was to see how deep their friendship currently is, even so, I would be disappointed if Madara abandoned Hashirama since I taught him well, I felt satisfied as I heard Madara talk ''Hmph, you think that just because you're stronger I'll abandon my friend? You're wrong! My nii-san taught me that some kind of people are trash, however, those that abandon their friends are worse than trash!''

I smiled before I started to talk ''Well, you passed my test, Madara, you too, Hashirama, I know you're already awake, haha''

If it were any other person, they wouldn't notice it but there's no one that knows Hashirama more than me and his father, I removed my transformation jutsu and the mask from my face, both Hashirama and Madara, that had confused expressions on their faces just a second ago, shouted at the same time ''Nii-san?!''

However, as they shouted at the same time, they noticed something wrong at each other with questioning faces, I have to admit, they're really similar, haha.
