Hou Niao tunneled into the sand layer, and for this "ground mouse", such terrain was not too easy.
The sand layer was loose, and after a thousand years of sediment, its thickness had exceeded five zhang. This was because it was at the edge of the Kneecap Desert, and the deeper one went, the deeper the sand layer would be, and the more severe the sandification.
Yuan Shangyuan's Dharma Form could penetrate through the sand layer, but couldn't get through the soil layer beneath it.
When Hou Niao reached the bottom of the sand layer, he could clearly sense the presence of the Water Element. It was several times stronger than what should be found under a normal sand layer, which clearly indicated there was a more moist soil layer beneath the sand.
Leaving behind Yuan Shangyuan's Dharma Form clone, he continued to dive deeper, quickly blending into the soil layer, discerning the strengths of the Water Element, searching for any traces of undead creatures' presence.
