Perfect Uchiha

" Okay, if stopping the process is genetic collapse, what is letting it run? "

" Scanning "

Shin tapped his fingers as his mind was concentrating on why this was happening. He wasn't a genetic expert, but he was a chakra one.

' I know enough about genes and a lot about chakra to understand this at least, what I thought was perfect combination obviously wasn't so, my body will go through a gene collapse any moment.. '

But this doesn't make sense, Hagoromo Otsutsuki was this makeup and so was the god tree.

Wait a minute, Shinnosuke's frowned as if he understood something.

And at that very moment his CI assistant spoke too.

" Scan complete, changes done are not suitable for human body, new organ changes are being rejected by subject's immune system. "

I thought so, Shinnosuke gritted his teeth, this was due to him achieving the complete evolution of Sharingan, the full nine tomoe Rinnesharingan.

' Maybe that is why the sage didn't give Sasuke the complete thing..? '

Sharingan in essence, was never made for human body, or even Otsutsuki body.

It was an organ of the god tree, Otsutsuki could use it due to them being the parasites they are, they were naturally compatible with digesting genetic material.

Humans aren't like that, so they had to evolve via natural selection and take what they could use.

The toned down regular Sharingan was the result.

Even mangekyou was too hard for them, everyone not named Otsutsuki goes blind naturally.

' I see, even the awakening of Sharingan when chakra reaches acceptable levels is body evolving to protect itself form chakra exhaustion.. I messed everything up with my forceful evolution. '

Indeed, the whitish cells of Hashirama are just cells of God tree, that is why it is so similar to white zetsu produced by the God tree.

He understood why even with such a crude operation, Madara's evolution worked, it was just the god tree coming back together.

' I thought Ashura chakra was enough, it is not, Ashura chakra isn't enough at all, the one in a million coincidence of Hashirama awakening wood release was also a requirement, Naruto doesn't have that. '

That's why Madara could body everyone using his rinnegan and Sasuke got bodied by his rinnegan, he didn't have the wood release.

Shin understood the crux of the problem, he was a human, and thus not suitable for the additional eye of God tree currently within him.

It was like taking a branch from a random tree and duct taping it to yourself, hoping you somehow grow leaves, body would start to reject the branch as soon as it can.

Now that Shin figured out the problem, he can find a solution.

" CI, scan what is happening to my body currently. "

As CI was scanning, Shin waited patiently, no reason to be upset on things beyond your control.

" Scan complete, the yang chakra of kurama is keeping subject alive, and it's radiation is assisting subject body to attempt a fix and stop immediate collapse. "

....

" Suggestion, let the process continue until DNA sequence is stabilized. The final result is currently unknown. "

Shin frowned as he nodded his head, this was the best course of action at present.

He kept tapping his seat as a new procedure was being developed.

" New procedure set, estimated time 2 hours. "

Shin didn't comment, he was smart enough to have around 2 to 3 hours leeway when he had made the plans, Hyuga's or Kakashi still won't start looking for these guys for a while.

Shin should be over by then.

" .. CI, tell me, how are the values I had calculated? "

" The values are similar but the genetic makeup is different. "

I see, thought Shin, then he shouldn't worry too much, the values he had calculated were fail safe values.

After a while of thinking, Shin suddenly stopped his tapping.

And smiled slightly, he just understood something.

" CI, check my body changes and list them. "

Scanning..

" Scan complete, muscle mass increased, bone density increased, nerve response increased, body structure fine tuned - "

" Stop "

Shinnosuke asked the CI to stop, he immediately understood what was happening.

" CI, remove code red, this is a false alarm. "

" Accepted, current status code orange, at risk. "

Shin nodded, this was fine, he was pretty sure of his guess but it doesn't hurt to be careful.

" CI, check if my body is still attempting repair. "

" Scanning. Yes "

Shin nodded.

" I see, that means my evolution is still ongoing, this is not out of the ordinary, I simply didn't see it coming due to my oversight. "

CI listened as Shin spoke of his deduction.

" The condition I had set up for evolution is what's keeping me alive correct? That is because I am still evolving! "

Chuckling, Shin spoke freely.

" What the Ashura and Indra chakra did was forcefully push me towards the genetic makeup of God tree, but now that it is done, there is one more step remaining. "

Narrowing his eyes, Shin poked at the crux of current problem.

" The step being, these new changes will need to be adapted to fit together with my human body, I am not god tree, cellular readjustment needs to happen. "

What Shin's body was doing was evolving to hold these new changes in ways a human body can.

And that would mean removing many unnecessary changes and keeping only the necessary.

That was the core of evolution.

" My body is adapting to the environment, Kurama chakra keeps me alive and it's radiation keeps the process running. "

Heaving a sigh of relief, Shin spoke.

" CI, add a new prediction, body should start rebuilding to adapt and achieve best biological human DNA sequence. Write that down. "

Shin made a bold prediction, he did this for two reasons.

One, the radiation from nine tails will stop affecting him only when his genetic structure is stable.

Two, yang was keeping him alive as a human, which in turn forced the genetic structure to remain human and not collapse into a meaningless mess.

" Noted, checking feasibility. "

...

" Success, currently prediction is looking probable. "

...

" Subject is evolving towards the perfect human DNA sequence, the end result is theorized to be - "

" Perfect Uchiha. "

Shin completed CI's sentence. With a smirk on his face.

This is good, something good did come after all from not blindly grafting Hashirama cells on his body, everything needed a process.

And Shin's process was successful, there were bumps along the way but -

" Error, unexpected circumstance detected. "

@#&*

Rubbing his eyebrows, Shin asked.

" What is it..? "

" Sharingan is going through a devolution. Currently losing tomoe. "

* Cough cough *

Shin almost choked on his saliva, what was he even here for then!

But he frowned again, he didn't feel his eyes weaken.

" Rinnesharingan has devolved to Rinnegan.. "

...

" Rinnegan is losing color.. devolving to mangekyou Sharingan. "

Shin just kept quiet, he didn't feel any weakening of his eyes at all.

And so he roughly had an idea what was happening.

" Rinnegan devolved, current stage mangekyou sharingan. "

...

" Devolution stopped. State, stable. "

Shin nodded, as he smiled, he knew what this was.

" I have adapted.. from ninja world's natural evolution it was pretty obvious every normal Uchiha could at max achieve mangekyou, that was because that is the human limit. "

Laughing out loud from feeling his immense pupil strength and the justus beginning to emerge, Shin was going wild.

" That's it! That's why Obito's mangekyou never evolved even after he became ten tails jinchuriki, human DNA can't evolve further than that, Ashura and Indra are aliens. "

But Shin knew what happened to Obito when he didn't evolve.

" His regular mangekyou became much stronger, so much so that he could affect truth seeking balls. This is what has happened to me as well. "

Shin laughed hard as he counted the influx of justus he just got.

He had them all.

" Human path, Ashura path, Animal path, every path of rinnegan, I have them. "

Shin may have lost his rinnegan but he kept all the paths as the doujutsu of his Mangekyou Sharingan.

" My Mangekyou Sharingan is my Rinnegan and Rinnesharingan..! "

Shin didn't care, as long as he could keep the justus and the eye power, he could care less how it looks, this might as well be an ascetic issue.

Who cares about that?!

But best of all

" I have it. "

With a wild look to his face, Shin whispered.

" Infinite Tsukuyomi "
