He doesn't even know he has conquerors lol.
Tell me what is haki mass?
Zoro doesn’t know that he has a Power called conqueror’s haki
Zoro knows that he has a power that he is using in KoH.
understand? Zoro knows what he is doing when he activates KOH. He simply didn’t know that it was CoC related
anyway haki isn’t some vague magic power that can do anything. For example, Haki mass or whatever cannot destroy Ragnir’s ice.
So there are things that Oda has written into the story that outscale haki. One of them is lunarian durability
you forget that Luffy, the Yonko, fought the seraphims for literally 12 hours and it’s revealed that they had to be put in seastone to be defeated and none of them were injured. Luffy, the Yonko CoC man, didn’t do shit to lunarians for 12 hours of fighting
