@jokerxhisoka Do they know where/who the Divine Sea Pavilion is? Because so far the answer seems to be a resounding no.
What is the natural tendency for corrupt officials who don't know how to complete a critically important task they've been given? Find a scapegoat.
And what do you know, the north guardian patriarch has a ready made scapegoat nearby that "stole his daughter".
And even if they do know where/who the DSP is, it would be perfectly in character for the NG patriarch to blame Xing He anyways just for a spot of petty vengeance.
