i wrote about that below.my personal opinion is that the df he had was something like hito hito no mi model:enlightement.he became one with this world.he could hear and understantd everything.thats how he could read and wright in poneglyphs.i dont know if observation haki can be upgadded 2 such a level.rayleigh didint mention if haki can be upgadded.could be.and oda never said that he made a mistake with rogers handcufffs in his execution.they werent made from seastone.we ll see mates.
