Well I have no doubt that Zoro has finally unlocked CoC, but it's going to take time before he can advance it to the level that Luffy can now utilize it in, if he is able to at all.
But nobody is convincing me that Asura is AdCoC. Too much suspension of disbelief going into that one. Asura being linked to Sandai Kitetsu, and the cursed blades makes way more sense from a narrative standpoint, especially considering their mystique in nature, and the fact that Oda isn't going to introduce the concept of cursed blades without making them unique in some way.
As for Me i need a full confirmation that Zoro has CoC! For now i put him an asterisks next to him having CoC.
If Oda can make Visuals for Ussop/Coby awakening CoO.
If he can show visuals of Luffy using CoC pre ts.
If he can show visuals of katakuri using FS and Fuji using CoO.
If he can make characters truly comments with certainty that X has certain haki.
Then he surely can do it for Zoro having CoC! Show visuals and make clear confirmations! Even if Zoro isn't aware of himself having CoC.
About adCOc I agree with you,
Ashura is linked to curses or blades than to CoC
If adCoC was about making some avatars of many heads then why doesn't Luffy and kaido mention anything about that?
We see adCoC is when people don't even need to touch you for them to hurt you.
Ashura : blade curses
