1.) The best way to find the Rinnegan is to catch her in a genjutsu. If he wants to search, he should use a Byaakugan instead of Sharingan.i think konan will stay alive but not for long i have 2 different way's for she staying alive
1. madara using his sharingan will take control over her and that way control the village of konan. and by the way he will get the sharingan
now he has a fighting force of a village for his disposal.
2. after a short fight konan uses some kind of teleporting or reverse sumoning tech to land in konoha she is barely alive and tell's what happend and where the rinnegan is.... while madara uses his sharingan to search for it.
I think she'll get the message to tsunade either madara gets the rinnengan she will definetly send a message... I hope so. Then probably I think Tsunade will resort to Naruto and bee...They'll probably go after madara.1.) The best way to find the Rinnegan is to catch her in a genjutsu.

2.) She'll get a message off to Konoha about Madara and the Rinnegan. Tsunade will be sitting at her desk when a little origami crane flies through the open window and lands on her desk and unfolds itself.
that's good idea, but if she is soon die then she will send paper with rinnegan to naruto and put note for him.she'll teleport to konoha and give the rinnegan to naruto. he'll put them in his eyes and that'll be that lol.
