All of the gods looked at Kai with confusion and then a bit of fear. They all had pledged their loyalty to Aion, so doing the same thing to his little brother felt weird. It wasn't because they didn't want to, but it was because Aion clearly lied to all of them about Kai's power had they didn't know if Kai was the same as him.
"It doesn't look like your knees are locked in place, because even with broken knees, one would be lower than my waist." Kai was basically telling them that if they didn't kneel, he would break their knees.
A few gods understood the message right away and knelt. They had seen what he did to the demigods and what he did during their prior fight, and they didn't wish to get hurt or killed.
"Good. I recognize you lot who kneeled. As for the rest." Kai swiped his hand and killed every last one of them.
Out of the thousand gods, only 10 remained. 11 if you count the woman from earlier.
