What was the point for Yang Kai to pretend to be weak even when the three divine spirits were already there? You'd think he shouldn't show those three any signs of weakness because he likes to bully them. Naturally they are only concerned about Ruo Xi, while they suffer Yang Kai's presence not to piss off Ruo Xi, but if Yang Kai treats them like fools, they will simply avoid him altogether in the future. If he can't contact them, he can't bully benefits out of them.
