Most people haven't realized but Oda gave Zoro 2 new styles with conqueror's haki.
The King of Hell sword style.
This seems to be a CoC upgrade to all of Zoro's old moves like Onigiri or Bird Dance.
And the King of Hell dragon style.
With this style Zoro uses a never before seen move and just annihilates everything in front of him, what happened is that Zoro blitzed King in the air from kingdom come, one of the fastest characters in the manga couldn't do anything about it. I think Oda is saving new moves for the KoH dragon style and that CoC might have given Zoro the ability to fly or dash in the air, not much compared to the timestop and reality warping abilities that people give to Shanks but it's something, after all Zoro is the only character in the story that can make illusions with his willpower, anything is possible with the strongest willpower/haki since haki surpasses everything.
