Naruto: I Rise to the Top with the Devouring System

It stands to reason! The protagonist has devoured so many talents in Konoha. Not to mention unlimited chakra, there is no shortage of it, not to mention it is comparable to Madara and Hashirama! That's also super cinematic! A huge amount of chakra ➕ a variety of ninjutsu secrets ➕ everyone's practice of changing the nature and form of chakra. There is also experience in practicing chakra of various attributes. If you stack up the senjutsu skills, you can even be able to match the Six Paths mode like Obito.

Nice looking, very good Naruto fanfic.
