The endless void is truly vast and boundless, even Ning Cheng's strength at the Primordial Stage, allowing his Divine Sense to penetrate dimensions, couldn't traverse the void from one place to another without utilizing transmission arrays. It's not that he doesn't want to tear through the dimensions and walk through, but with his current strength, he still can't achieve the ability to directly penetrate several dimensions, and then directly tear through the void to reach his destination.
Traveling through the vast void, the only thing that's worthless is time. Ning Cheng and others continuously switched transmission arrays, teleporting from one Star City in the void to another. Two years had passed in such a way, flying between transmission arrays and Star Cities. And this was with Elder Gas controlling the Starry Sky Wheel, saving a substantial amount of time. If it had been Bull Chasing controlling the Starry Sky Wheel, the time probably would have doubled.
