Ok jus thought about something if madara didnt die at the valley of the end and he lived to somehow know nagato then why is he revived in his younger state it seems that edo revives you how you were when you died so shouldnt he be old if not why didnt kabuto summon an prime chiyo also the tech that nagato used to absorb bee and narutos chakra to regain his prime body couldnt madara have used that tech to stay alive if he lived that long
