The void is a borderland where Laws do not exist, a peripheral zone between worlds. To travel from one world to another, one must almost always preset the desired coordinates and then engage in Space-Time Travel.
To most Cultivators, the void appears as a deep tunnel, not a boundless, starry expanse.
Even someone at the Harmonization Realm like Celestial Star was incapable of traversing extreme distances. He rarely crossed through space and time, as doing so consumed an unreasonable amount of mental energy and Spirit Charm.
Otherwise, he wouldn't be in the Desolate Realm using special communication methods to contact his subordinates. While traveling directly to Blue Star would be faster, it would also consume a great deal of his reserves, requiring a period of recuperation to fully recover.
