The First Hookage's Secret Scroll of jutsus
We all know that at the beginning of the Naruto series, Naruto steals the First Hookage's Secret Scroll. Which contained very important secrets about the village and forbidden jutsus.
Naruto learned one of them, the Shadow clone jutsu. I am pretty sure that scroll contained much higher level jutsus, and in order to peform them, the user needs to combile other jutsus such as the shadow clone. Like how naruto use shadow clones to use rasengan(since he cant do it single handedly)
It would be interesting if Naruto learned more jutsus from there, we could then know what were the great jutsus that all the past hookage's could do. Somethinng that the first Hookage used to defeat Madara.
If sharingan was so god damn strong then how come the first defeated him without any eye technique? "The Senju Clan Ruled!"
