I dont get this. We know for a fact Fuji can distinguish all the rubble(=stones) in DR from everything else! Therefore CoO can read stones if u got the right CoO that is. And if Fuji does what he does in DR with rocks by the use of his CoO, i dont see how what Zoro did in Alabasta is any different!
It also fits all of Luffys/Ray-sans description of Haki and how it improves/awakens. Zoro was at deaths door at that moment, with Luffy/Ray-san explaining that dire situations are what leads to ur haki to improve i just follow whats been said.
BTW i find it very weird that Katakuri still lets Luffy the time to recuperate.....he aint attacking him whenever he is already lying down most of the times, instead he often waits for Luffy to stand up , even encouraging him to do so.
Then again he has stated numerous times in several chapters whether that was all that Luffy was able to. Even in this chapter he asked again.....i mean ok that still signifies huge superiority, but aint that far too risky? Luffy grow rate should ring all his alarm bells....i just dont know anymore.....i mean so far Katakuri still seems vastly superior his better CoA was shown once more this chapter but.....strange..its just strange....i fear some plot armor is coming up again......like .... soemthing real stupid.....like Katakuri cant fight if not given the time to take a pis* every day or so..... pls Oda dont do somehting like plot armor again..... Luffy won far too many fights because of that already.....
@Kazekage could be right, Katakuri may simply really enjoy this, thus trying to keep it going.
I think it's because Katakuri wants to break Luffy's spirit. He wants him to admit defeat. I kinda see it as plot armor because that shouldn't really be his concern but it seems to be the case.
