ok it says he's a mokuton user when madara has EMS.Mokuton means wood release
and what do you mean by strength? The techs he learned like flower tree world? The size of the wood?
Did you see how Obito was able to decimate the Hidden Mist shinobi without having any experience at all at using mokuton and create that huge spiky tree?
I'm saying how do you know hashi mokuton never got any stronger ?
