Bei Yin Mountain.
Despite its name meaning "shaded from the sun," it didn't actually face towards the sunlight.
Within the mountain, a Cave Heaven naturally formed, nurturing three thousand extreme path Devil Gods.
It evolved from a nine serenities mysterious monument that was originally no bigger than the size of a palm, becoming the core of this Nine Serenities Secret Realm.
Of course, it was still only in its rudimentary form at present, and it needed to develop and evolve along with the Secret Realm, eventually maturing into its final form.
This evolutionary process shouldn't take too long.
But even though it was merely in the rudimentary stage, it already possessed some outstanding features.
