The teacher gave Gravis the location of his next opponent, and Gravis thanked her again. After that, he talked with Stella for a little bit and gave her a spot where they would meet again. It was just a bit outside the Unrestrained Sect.
Gravis would probably be busy for an entire day or so since he had to conquer multiple resource points.
When everything was done, Gravis left the three of them alone. He wasn't close to any of them, so he didn't really care about the teacher's death.

SHING! SHING! SHING!
Three Immortal Kings appeared before Gravis.
"Report! What has happened in there?" one of them ordered.
