Of course, for the average independent cultivator, as well as for external sect disciples below the Golden Core realm, whether the local spiritual vein is guarded by a mountain god doesn't make any difference at all. After all, they're dealing with a 'god', and unless you hold the sect's command flag or the decree of authority, they wouldn't bother with you at all.
However, for those in the True Human realm, especially for the True Humans in charge of guarding, and magicians with official positions within the sect, having the assistance of a mountain god in the locality is a significant boon. It's akin to having an invisible protector; during conflicts, there's no need for elaborate rituals — a simple charm can directly call upon the spiritual power within the vein.
