Let's talk Business

He raises his head "I wish to become Uchiha Madara!"

There was a choke sound echoing through the void as soon as he said his wish.

[Y-you gotta be kidding me! That-]

He instantly interrupted the voice "You said one wish not one power, again.. is all on the details" if he could grin, he would have a massive evil grin from ear to ear on his face right now.

[T-that's….]

"Are you going back on your word? God?"

[You can't have the full power of Uchiha Madara! The world laws wont bend that much! It's impossible!]

"But that's what we are doing here, its all a negotiation, lets talk business, how can we balance it?" he suddenly incarnated his inner lawyer, fighting for his own cause!

[NO RINNEGAN! THAT'S IMPOSSIBLE! YOU EVEN SAID YOURSELF THAT YOU DIDN'T WANT PEOPLE SPAWNING METEORS!]

"Fair enough" he waves his hands dismissively, honestly he didn't care about the Rinnegan, he didn't pick Madara just for his power, but he will try to squeeze every single possibility out of this god! "All I want is an Eternal Mangekyo Sharingan and I'm fine"

[Its also impossible, the ocular powers of each eye will break the laws!]

He thinks for a second, without the eye powers having a Mangekyo Sharingan becomes quite useless except for ... "Give me a 3-tomoe sharingan that also allows me to use Susano'o without blindness then.. it's not too unbalanced"

[How is that not unbalanced?! Susano'o is a freaking war god!]

"The spirit world exists, so such power should be doable if we bend the laws to its limit, lets see a possible way to make Madara work in the Avatar world, make me a firebender, you can take all the jutsu away sinse chi isn't chakra i just want my talent for firebending being equal to Madara's talent for ninjutsu, replace the chakra pool for an equivalent chi pool, the Susano'o can be treated like a guardian spirit under my control or something and the defense should be roughly similar to Aang on his ultimate Avatar State against Ozai! See? Easy!"

[Easy you say?!]

The voice stopped talking for a bit, although its stretching to the point of nearly breaking the laws it's possible, the sharingan would be an outlandish power but not to the point of being incompatible with some spirit powers, no six paths, no kyuubi summon, no mokuton sinse he accepted being a firebender, he won't be able to use actual justsu since it's not compatible with avatar's chi, no Izanagi or Izanami..wait..

[The genjutsu its out of limits!]

"Why? Illusions are a thing that more than one spirit can do, energybending is a thing! And its not limited by the world laws of bending, anyone could technically learn, even if they already are an elemental bender or not a bender at all! we can link genjutsu with energy bending or something like that.."

[Only basic Illusions, nothing on the level of mangekyo sharingan!]

He nods "Fair enough"

[Phew … on your power will be that then]

He shakes his head "No no no.. I didn't ask just for Uchiha Bloodline as power, I asked to be Uchiha Madara, although I lost many of his ultimate moves, I want the rest of the package! Taijutsu skills, combat experience, appearance, even Gunbai, make the Gunbai reflect the bending back to its bender, and it consumes my Chi every time it does, it's not THAT unbalanced, all I want to keep is my own personality and memories, none of this would be worth it if I just cease to exist and becomes the actual Madara, I want to enjoy my life, I think I deserve it." he shrugs

[… Alright.. by the way, you really went for the overpowered wish huh?]

He shakes his head "That's not it, you see Madara wasn't my first thought, Itachi was, but i knew you would freak out about genjutsu, and although even after the 'balancing' Itachi would still remain quite strong, why settle for that when I can go for Madara? Way more combat experience and I won't have to worry about any possible disease that would've gotten me killed by the age of 20, I could've picked Obito but I knew you would never let me have Kamui so what's the point of that?"

He also didn't know if by picking Obito he would've gone to the avatar world with a half destroyed face and mutilated body and a single eye, it isn't worth the risk if you can just pick a better wish.

[… Very well, but the Gunbai will have a simple spirit fused with it so it can reflect things, it will only activate with the sharingan, but anyone else can just take it and use it as a regular weapon, by no means it can be 'summoned back to your hand' or anything like that, so don't lose it!]

After that a soft glow spread all over the light in human form, indicating that the wish was granted.

An evil grin would've been all over his face right now if it was possible'the voice didn't reject the details, it was so fixed on the big stuff that it forgot a tiny bit detail, Madara chakra pool is MASSIVE, turning that amount into chi would make me have near unlimited chi when compared to ordinary people, hell I bet only an avatar in the avatar state would be able to outlast me since that they get unlimited chi in that state and that's not even considering the destructive power, adding Susano'o.. heh.. I can win!'

If the voice had a head, it would be having a nasty headache now.

[Now about the 5 knowledge points we are giving you, you don't have to worry about Madara related skills, you will already know them all as they come with his experience that you asked, but things related to the avatar world will demand using one of the points that we gave you, the genjutsu is part of package, but any extra energybending would require for you to learn and comprehend on your own.]

He stops to think for a bit, he knows a lot a about avatar, more than a lot considering that he knows everything that was possible to know from Aang's awakening to the end of Legend of Korra, small things in between are irrelevant and could be learn as he goes, and there was 100 years of war before Aang but considering how everything was around the existence of the Avatar, most of the needed stuff was already known, except for some.. obscure… knowledge that the show didn't go too much into detail.

"Fist knowledge would be.. I want to know all languages from the Avatar and Spirit world, how speak, write and read them!"

[Smart! It's a detail that most people would skip, as I said, anything from the avatar world would be unknown, and language, how to write and read in its various forms would obviously be unknown to a transmigrator.]

With click sound, another glow appears around him, the knowledge was acquired.

"I want to know how to achieve immortality, at least biological immortality as becoming ageless" the key of the question is on the 'how' if he asked if there was a way, the voice could just answer with a yes or no, but asking how it gives him direction, and perhaps a possibility of using another knowledge point to get it, it may cost 2 out of his limited 5 points but c'mon, eternal YOUTH is worth it isn't it? He might be able to find this information in Wan Shi Tong's library but.. have you seen the size of that place? He might die of old age before finding a clue about it, he is no avatar, the spirit wont spare his time to help him!

[Are you willing to sacrifice one point just to know that?]

He nods

[.. sigh.. it's related to opening your Chakras, done on a specific way will give you many useful perks, it won't directly empower you but will make you highly immune to many things and age is one of them, eternal youth is impossible, but you will earn a greatly increased longevity, on top of that once you reach your peak your body will only age again on the final 10 years of your life, eternal youth, or as you said, biological immortality, should be considered a curse for a mortal, not a blessing.]

He stops for a second, and stares at the void for several seconds thinking of what he just heard 'Things are more beautiful because we are fated to die, huh? Well I can't disagree with the voice, I doubt I could attach myself to anything if actually had immortality.. it's just… who never wished to remain young forever?.. perhaps is just my fear of death due to my past life...sigh.. but it is as the voice said, after certain point it will become like a curse.. watching everyone around me die while i remain, just thinking about it already depresses me.. I could share the knowledge and keep them alive too but, how many generations can I keep doing that before we all lose our sanity and our humanity..'

"If that's the case my soul will be destroyed after my death because I am an anomaly.. is it really worth it?"

[Now now, I understand your worry, but I said I would tinker your soul, so when the time comes, you will not be destroyed, you will come to me for your final judgement, you won't be able to reincarnate but heaven's door will be open for you just like a natural soul, I know that now you think that we could just 'fix' all the others like you, but it is as I said, although uncommon, it's not rare, there's too many like you, we would have to spend a tremendous effort just for that goal, and we are talking about the multiverse here, it's not just humans, is not just a bunch of planets, it's a nearly endless universes, even for us it's .. difficult..]

He nods "from the perspective of an earthling is really hard to imagine the scale, just like saying something is 10 million times the temperature of the sun, we can tell its absurdly hot but we have no way of understanding the actual scale, our imagination is limited by our knowledge"

[Very wise words, to think you had that much wisdom in you.]

"To think that you had that much sass in you.."

They both laugh for a while then they go back to their negotiation

[So, what else you want? You have 3 points left]

"I want all the knowledge you can give me related to the Chakras, how to open them and everything!"

[Though so.] another glow appears around him.

[2 more]

"I want the knowledge of the best firebending technique in existence, including the best chi breathing technique to improve my chi pool"

[Very funny, you think I'm one of these 'ROBs' that accept 3 wishes in one because they were requested together? The language one was acceptable because there aren't many languages in the avatar world, and the knowledge itself its quite simple, but this one will cost you your 2 last points, is that what you want?]

He sighs 'well it was worth the shot..well I will have to learn conventional energybending on my own.. if Amon achieved it on his own.. so can i, i might not have bloodbending but i refuse to believe that theres only one way to do it!' nodding he replies "Yes, its acceptable, was a pleasure doing business with you.. voice…" and two more glows appear around him, one after the other.

[hahaha, yes it was very entertaining, I hope I don't see you anytime soon]

"Yeah I don't want to see you soon either, but when I come back I hope you welcome me as an old friend"

[Sure, so should I send you two years before Aang's awakening? Is that acceptable?]

"Wait, do I have a choice?"

[More like a timeframe, I can't send you too far back otherwise the butterfly effect would be disastrous, I am sending you there to help the world not to ruin it]

"How far back can I go?"

[Hmm… I can send you ten years before Aang's awakening, right after Katara and Sokka's mother is taken, saving her would bring them joy but it could put the fate of the world in danger, so I can't allow it to happen, but sending you that far on the past will add some limitations on you until roughly two years before story begins.]

"Fair point, and when will my reincarnator friend arrive? Any hunting tips?"

[I don't know, it is marked for reincarnation so I assume it will be at some point in the timeline, keep an eye out for outlandish things, Reincarnators have an awful habit of using their knowledge openly, be it creating technology or bringing food recipes from their world, they are pretty easy to spot, the same for you.. being Madara and all that..]

"Noted, by the way, if they are good people, should I kill them regardless?"

[I will leave that to your judgement, this is a trial and humans are quite unpredictable creatures, who knows, perhaps the reincarnator is good hearted and you just earned yourself a free life in the avatar world to enjoy]

He laughs "hahaha that would be nice…" he stares at the portal appearing behind him, it almost looks like the hyperspace jump from Star Wars, floating towards the portal without looking back, but then shouts.

"BE A CHAMP AND SEND ME TO THE SOUTHERN AIR TEMPLE PLEASE, I DON'T WANT TO APPEAR IN THE MIDDLE OF BA SING SE SEWERS OR GOD FORBID, OZAI'S RESTROOM"

He hears a loud laugh from behind, it seems that the entity really is amusing and fun, do they miss this kind of carefree talk? Who knows, perhaps most souls don't talk like that to a god-like being with untold powers, he wonders if being a god is boring.

But just as he reaches the portal a final glow appears around him, instinctively turning around he starts to be sucked into the portal and hears a booming voice

[CONSIDER THIS A PARTING GIFT, SO YOU CAN PLAY NINJA IN THE AVATAR WORLD!]

And like that everything disappears, his consciousness is gone and when he finally wakes up, he finds himself laying down on a stone floor, staring at a broken ceiling, gentle clouds drifting through the sky and gentle bird sounds in the distance.

Leaning forward on a sitting position, he looks around the ruins of the southern air temple, quite well preserved if you ignore a few broken walls and ceilings, looking at himself for a bit he notices that he is wearing black robes, like the ones Madara used to wear when walking around Konoha, then he looks at his hands, small child-like hands perhaps 8 years old?

'Motherfucker.. they could've told me about the age thing.. sigh.. so these are the limitations of going this far back..' standing up he walks to a balcony like are staring down the mountain, inhaling the pure air 'at least It gives me more time to learn and master everything before I grow up..'

Turning around Madara walks back inside the temple with a satisfied smirk.

"Let's do this"
