first, the god tree didnt found anything be it heaven, earth or chakra.
second, MC looks like he is going to be a sog.
third, there is no such thing as refining chakra since you create it yourself, what is there to refine when its already yours?
I would like to kn how the MC managed to skip a year and join year 2 academy class. he shouldn't have been able to do so as only kakashi was able to do so because he's a genius.
