I'm so bored I came here after ages of not posting just to say this.

Remember I said the 3rd got hokage at a young age and everyone said i was being too literal but a future chapter confirmed it. Ok so basically when orochimaru was around the second would have been dead based on the ages of the characters as orochimaru wasnt around at the time the 3rd became hokage. SO how did he learn edo tensei if only the second knew it and was already dead before even orochimaru's birth? Also if the third is the professor who posesses all the jutsu how come he didnt know it? Anyyyyways back to not posting for ages.
