The sacred land is mostly used for burying people, not for living. That's pretty interesting.
Because the living might squander the family fortune—no matter how much wealth there is, it can all be lost, and no one can guarantee their descendants will be competent. But the dead are different—they won't squander what they've left behind, and a sacred land can even bless the descendants, granting lasting luck and prosperity.
So just like Divination Skill, Earth Divination Skill is vague and elusive, full of hearsay and mysteries. No one can say for sure how useful it really is. Believers are everywhere, and so are skeptics.
But the higher up people are, the more seriously they take Earth Divination Skill. To sum it up in one phrase: Better to believe it than not.
Anyway, if you have the conditions, it's just some extra effort; what's the harm?
