Fragment: Eternal Mangekyo
There are 3 timeline pages that aren't too hard to get, but require you to get 5,000 chakra fragments for the Residual Chakra Collection quest. Once you reach 5,000 chakra fragments, Gekomatsu will talk about a incredible fragment, and asks you to check it out. Go to the Western Land of Lightning, to the place where you fought the Jinchuriki, and run up to the purple crystal with a dark aura. Complete the battles you get there, and you'll have the 3 timeline pages added.
Hope it helps guys
