Qin Zheng inclined his head and stared up at the starry space. The experts who came here already flew up into the air. Even if Qin Wentian was here, it wouldn't be an easy task to find him. This place was the starry space and not on the ground. It if was on the surface, his immortal sense could easily sweep through the vast space, no one would be able to escape evasion from him. However, in the starry space where the nine heavenly layers existed, he had no way to do so. Just a single constellation was already as large as an immortal realm.
For some people who wished to head towards constellations that were further away, if it wasn't for this ancient pathway being able to shorten the distance, they could only depend on their own flying speed to reach where they wanted to go. It was unknown how much time would be needed then.
This ancient heaven vault pathway seemed to be able to extend indefinitely into the sky.
