Basic more of a bunch of head canons.
Nothing suggests Zoro used Adv CoC and not even KAIDO mentions that, pretty much just dumb reasoning to believe a guy has a Advanced version of something he doesn't even knew he had.
We know for sure only that KAIDO, Luffy, Roger and Whitebeard can use it because either Luffy confirmed KAIDO using or we could see it by Oden's and Law's reaction when Luffy literally did the same stuff they did.
You literally dodge every point which I made, you not even try to answer my points but rather saying stuff who never be confirmed in first place. In fact Kaido said Zoro use CoC in his attack and attacks who are based on CoC are the adv version, why you deny this point.
As I ask you when Luffy ever use adv CoC until this chapter come out? Never, since no one with basic CoC could combinate their attacks with CoC, not even Luffy until this chapter come out and you wanna try to say me Zoro who has less CoC can fuse his CoC with his attacks?
Kaido get hit twice, one time he not make any comment about Zoro but when Ashura get use he make a CoC comment?
Isn´t this clear? Ashura is clearly the source of the coc power from Zoro, like it or not bro.
