Although Barren knew that Elsa's calmness was feigned, he didn't expose her because he understood why she was doing it.
"Alright, Elsa's situation has stabilized, so it's time for me to leave. What's everyone's plan? Is there anyone who wants to leave with me? If you don't leave now, you'll have to wait until Elsa completes her awakening from the Awakening Pool." Barren looked at Guding and his group.
"I'll go out with you."
It was Robert who spoke; she's from the Mechanical Clan. The energy in these waters is of no use to her, so staying here doesn't hold much meaning.
"Anyone else?" Barren nodded, then glanced around again.
"Probably not..." Guding also looked at the others behind him; it seemed everyone wanted to stay and cultivate, "You can just take Robert with you, and the rest of us will leave together once Elsa completes her awakening."
"Alright then," Barren said as he looked at Robert, "Follow me!"
