[Discussion] the real question + asspull theory.

[sn0wy]

Okay, as we all know we know a few things about rennie tensi yet there are a ton of questions left unanswered.

1. There is no time limit on how long someone has been dead as to when they can be revived? This has been seen with madara and even with only one renniegan.

2. Apparently it only turns your hair white if your out of chalkra? or is this actually the result of using the jutsu you damn near die? I honestly don't think so because pain did like 500 ppl and turned white and obito just did one...

3. Apparently someone can be revived from not only when they died, but to an earlier time? as seen with madara....

And i'm sure there are many more things that can be said about the jutsu, everyone keeps saying what if itachi or minato get revived blah blah blah.... okay... i got one for you... to end this ****ed up system why not revive everyone from the begging of the true war?... Like from the times that hashi and maddy first fought... the last 100 years?... Revive everyone that was killed by a shinobi that didn't die of natural causes. Erase the hate by bringing them all back?.....

okay who can do this? well anyone with just 1 rennigan has shown the ability to do this. We have also seen naruto and sakura share their chalkra with people to make the sharingan stronger.. So why not make the rennigan stronger by sharing the chalkra?.... A 100% sakura and 100% naruto giving chalkra to sasuke why wouldn't he be able to revive everyone? Even if it wasn't done all at once it could be done in a year?....

So why wont they come back? plot no jutsu or maybe that's just whats going to happen on the last page of this manga who really knows..... Maybe that's how sasuke will finally be recognized by the village. He truly will revive his clan, quite literally. lol

If they can do this then why now or earlier? They needed all their chakra for battle.

the reason for madara revival is probably because his soul was close by, however it seems that if the soul is too far gone then its impossible.

I think the hair would turn white no matter what, because i think your trading your life energy to give it to someone else or something like that, this is just my guess after all.

Reviving just one person from long ago seems possible as opposed to trying to revive many within a short time period. Or perhaps it was simply possible because his soul was close by in an edo body, as Cael said.

Cael's life energy explanation makes sense for the hair turning white too. No matter how many you're reviving, the jutsu requires an exchange of life energy, perhaps, and turns the hair white no matter what.

Madara's revival was special as he was a specially altered edo thanks to Kabuto. Kabuto revived him old yet returned his youth by adding Senju DNA to his body. Since his edo was youthful, his revival adopted that youthful state. It all fits into what we'd expect in that situation.
