Mortis went to the Myriad Sect after saying goodbye to Arc.
Arc also vanished. He wanted to get back to baiting arrogant Cultivators.
And Gravis?
Gravis wanted to check up on Stella.
Stella was still in the Shining Purity Sect, and Gravis didn't want to take any chances.
What if they managed to find out about her true affiliation?
After Gravis became a Star God, his speed had increased dramatically.
Something that would have taken him an hour to traverse now barely took two minutes.
After about half an hour, Gravis arrived near the Shining Purity Sect. Of course, Gravis kept himself hidden with the Law of Perceived Reality. As long as no one questioned their perception, no one would be able to see him.
The Shining Purity Sect was on a high mountain surrounded by several shining stars. These stars had obviously been created with some Matter and Blaze Laws, but their light used the Purity Element.
