Kaido screaming in fear from the fact that Big Mom is arriving to Wano with couple of her children, while she left the whole army in WCI. And Kaido was still freaking out

Again your reading comprehension is so bad man.
First you start counting chapters in which Kaidou proved he's not trying to finish the fight.
Chapters should only be counted from the moment Kaidou said he wanted to end the fight, because we really know that from that point on he would really try to do that, does that make sense to you?
And now you make the same misunderstanding, proving the mediocre reading comprehension you have, see if your logic makes sense.
