Yes, this part in particular
Did King get pushed back by a coc-forcefield or something
Either way, looking at King's dialogs, it kinda starts to make sense why he asked if Zoro wanted to become a king.
In his eyes, Kaido is the one who can change the world. Adcoc haki is viewed as a sign only the very strongest could use by Kaido
And according to the translations of this spoiler when Zoro named his king attacks, King had to remind Zoro that Kaido was the one who'd become the PK
That suggest that he views adcoc users as potential threats to the throne
With Oda overall using the adcoc barrier(Zoro, Yamato, etc) as a sign of people exceeding King's perspective and overall level(YC1)
