Splendid Chapter!! I want to be sure that the translation is correct and give my opinion later.
In any case, Zoro meditating and thinking was a really good moment, he get the thing done in an instant. Before that was pure caos there, and Queen was enjoyed it.
The moment where Zoro had it enough, he destroyed Apoo (drake was shoked), he gave the cure to Chopper and was so good seeing both interaction. He interrupted queen (queen is shocked) by cutting his rifle with an ultra fast and strong slice that cover huge distance (YC feat without any doubt), showing that Zoro has a great COO.
And last he shout to all people that he is going to slice Kaido which make totally sense for a guy that is holding Enma and need to achieve the blacken blade feat.
About the CoC, I am sure that many people there had the impression that Zoro used some kind of ambition (zoro did deny that) still pretty sure it is a foreshadowing if not a confirmation that Zoro ll use CoC in this arc!!!
