Border.
The farther from the Ancestral Mountain, the more barren it becomes.
Because on the Ancestral Mountain, there are twelve spiritual springs planted by the Ancestor.
The Spiritual Springs are incredibly rich.
Apart from a few locations, the closer you get to the Ancestral Mountain, the richer the Spiritual Qi, and the faster the cultivation.
In other places, even if there is an abundance of Spiritual Qi, it often contains more impurities.
The so-called Spiritual Qi impurities, of course, refer to those black particles.
In the past, cultivators regarded black particles and Spiritual Qi as the same, absorbing them for cultivation.
But now, black particles have been identified as substances with great detriment to cultivation.

But even so, very few cultivators dare to do this.
