You're jumping the gun, all we know is that Zoro defeated Lucci. Nothing else. You make yourself a target of ridicule by making statements like these.
The funny part the chapter isn't even like that
And btw Zoro didn't one-shot Luffy since we saw him being blocked by Lucci
That's no one-shot if the person blocks your attacks
Same way Luffy didn't one-shot Kizaru despite taking out Kizaru in one connected blow in round 1
One-shot is when you only attack once and win
