Why did Wang Jian Sanchunyang Shence Army pursue Xu Jingyi's disciples?

I almost forgot the plot _ (:з∠) _

There should be two reasons, one is chasing Princess Jade Qing, and it may be that Li Muyun has a pulse of static deficiency.

Secondly, it should be because Xie defected from Chunyang to Japan, and then his disciples suffered.
