Even the Demon Clan in Beijulu Continent is far less rampant than that in Xiniuhe Continent.
Though the Demon Clan in Beijulu is numerous, they keep a low profile. Unless necessary, they won't step out of Beijulu even a half-step.
But that's not the case with the Demon Clan in Xiniuhe Continent. They not only rule over the place, but each of them also claim to be a Demon King, making quite a name for themselves in the world.
Even Jiang Chen, who lived far away in Nanbuzhan Continent, has heard of the names of the various Demon Kings of the west. Thus, one can see how rampant they are.
Xiniuhe Continent, in fact, is also the main stronghold of the Buddhists. This is where their Holy Land, the Spiritual Mountain, is situated.
In the eyes of the Buddhists, the Demon Clan is rampant and commits all sorts of wickedness, yet they turn a blind eye to it all.
If there wasn't somebody influential from the Buddhist door backing them, then it'd be really strange.
