The sect didn't move as fast as a cultivator like Xawery could, but it definitely wasn't slow. The speed was something similar to what a Saint Realm cultivator could fly. Considering its size, it was definitely impressive. Since the sect never accepted disciples below the Elemental Transformation, there was no risk of a cultivator going out and being outrun by the sect.
But then again, just how big are the regions of a place like the Divine Realm? That was why the Sect already expected to spend many, many years on this journey. That was also one of the reasons the entire sect was brought along. With it, there were enough resources to last a thousand years of constant consumption if necessary, not to mention it was a base for their rest. The sect was truly betting everything in this journey.
