When the Formation had not been triggered, not much could be discerned, but now as the three made their move and activated the protective array, some details of the valley below were revealed.
A massive protective array, like an inverted bowl, enveloped a good half of the valley. The spirit force flowing above the light screen did not disperse, highlighting the richness of nature's spiritual energy in this place.
If previously Tan Sheng and the others merely suspected this might be Lu Ye's hideout, after seeing this protective array, their certainty had increased by at least seventy to eighty percent!
The strength of a protective array is directly linked to the concentration of nature's spiritual energy, the more concentrated the energy, the more potent the array.
This array, covering such a vast scope yet still maintaining such impressive strength, indicated that the spiritual energy here was definitely that of a Class A spirit ground.
