The so called "Three Qing" referred to the three highest status Protector Gods of the Taoist Faction.
They defended the Taoist Faction and didn't have a mind of their own so naturally there weren't any conflicts.
However the people under them were different. The Taoist Faction has a billion disciples each with their own thoughts and interests as well as demands. Thus there were these three factions, Vast Habitat and two sects which each grasped its own Protector God Spirits.
Actually what Zong Shou cared most about was the technique to form the God Spirit.
Unfortunately this Mingsheng Temple Sect Leader knew nothing about it. The Tailing Xuan Lord that was worshipped here was sent over by Daoling Vast Habitat and formed it for them. Mingsheng Temple didn't interfere and thus didn't know anything about the mysteries within.
