The nine prayer beads on Sha Wujing's neck are actually transformed from nine World Suppressing Steles. The Myriad Blood Halberd was originally forged from these nine World Suppressing Steles, but once the Artifact Spirit was lost, the Myriad Blood Halberd reverted to its original form; the blood and soul of the billions of creatures dissipated, causing the World Suppressing Steles that formed the halberd to naturally separate. Of all those present, both Sun Wukong and Zhu Bajie possess the ability to control the Wasteland Soil Stele and Ultimate Water Stele, but at that time, the nine World Suppressing Steles were intertwined with each other, making it impossible for Sun Wukong to control them.
