The Lost Soul Sand was indeed no ordinary treasure; to refine such a weapon capable of tainting other's magical treasures, the yellow-robed large man had secretly killed an unknown number of low-level cultivators, harvested their souls and Primordial Spirits, and used a multitude of rare materials, taking over a hundred years of hard work to finally succeed in its refinement.
In the past, when they encountered powerful enemies, the two large men simply had to release the sand, and it would almost always come out triumphant. Even when facing adversaries of the same rank, this treasure still displayed its mighty divine powers, repeatedly achieving miraculous feats and even creating a significant reputation as "the Elder of the Wild Sands" among the offbeat and unorthodox paths, becoming a famously distinguished senior expert.
