After settling in the underground fortress, Qin Shou returned to his room and didn't go looking for Leng Wanbai.
The cosmic creature metal still required Mark's involvement, so Leng Wanbai obviously wouldn't stir up trouble at this time.

"I just want to be a good person!"

"Crunch… crunch…"
They jumped out of their cockpits and stood looking down at the Mechanical Valley from above.
