Zhang Chen, upon hearing this, thought the other party made sense. As he looked over, he indeed saw that the mound had been smashed to pieces, turning entirely into ready-made gravel.
Considering the special nature of Buzhou Mountain, Zhang Chen selected the Buzhou Mountain Stone as one of the gravel types for the Sand Merging Skill. He simply sat within the stone cave and began operating the Sand Merging Skill. He saw that strands of essence qi were continuously being drawn out from the Buzhou Mountain gravel and refined into Zhang Chen's Ha Acupoint, laying together with the vast yellow sand of the Sea of Blood.
At this moment, in the illusionary Ha Acupoint of Zhang Chen, the first layer was the yellow sand of the Sea of Blood, and the second layer was the sand of Buzhou Mountain.
