Although Bai Yu had attained the Enlightenment of the Dao, become a Primordial Daluo Golden Immortal, and advanced to the Thirtieth Tier, he still had not refined a currency one level above Sacred Spirit Stones.

Even if he managed to refine one, no one in Multiverse City or the Chat Group could use it—or afford it.
Of course, the main reason was still that Bai Yu could not refine it.
