Who is the "One who knows everything" that Sasuke is seeking for?

[Deadboy]

Its Rin! jk....Kinda farfetched but what if it was the Great Toad Sage, I remember somebody making a post with a theory about Fukasaku being the S06P, as if instead of the S06P dieing, he turned into that old toad. The reason his eyes were always closed, and his age being a factor.

I'm hoping its the Kages. Maybe Orochimaru has found a way passed death reaper seal...Or maybe its Shisui Uchiha or other significant Uchihas will be brought back...

The One Who Knows Everything is Shisui Uchiha

so6p,konoha elders, 1st hokage (wild guess)..........or maybe just maybe.....the founder of the uchiha clan oooor...madaras dad? so they can find out why madara had those motives in the first place

it is certain however, that sasuke needs Oro to immediately use that scroll
