Hmm, I've changed my mind on it. For now, I think Zoro didn't draw blood from Kaido or otherwise significantly damage him this chapter. I might reconsider if the Viz reveals that Kaido indeed complimented Zoro and Killer on their attack.

@Geo.
Kaido said "well done"
Then went on to call them monsters in their own right.
He complimented all of them even though they didn't damage him
