Gravis exited Arc's clearing and traveled to the Nine Elements Sect. Since he had become quite a bit stronger, he finished the journey in just a couple of days. Even more, Gravis no longer needed to avoid any gatherings of Cultivators.
Yes, cities and important locations had beast crystals, but as long as Gravis kept his Law of Perceived Reality active in his surroundings, no one would notice if the beast crystals shone. Gravis couldn't control the beast crystals, but he could control the perception of everyone around them.
How many beasts straight up entered a big city?
Nearly none.
These beast crystals only existed as a precaution, but they very rarely started shining. After all, nearly all the beasts would be killed on the frontlines.
