Knowing that they weren't in a deadly situation but had instead just been trapped inside a seemingly harmless formation that didn't cut of spiritual qi and allowed those trapped inside to cultivate, Chun Hua and Qing Yi weren't that afraid of the situation they had found themselves in. Understanding that with their current cultivation, they didn't have to worry about starving, and the worst-case scenario would be them waiting around for a few years until their master realized something was wrong and decided to check up on the two of them.
Neither of them were worried about their master being unable to handle the ancient spatial formation, as they were both aware of the fact that their master was skilled in both the Dao of Space and the Dao of Formation and in their eyes, was someone more than strong enough to handle the spatial formation that had trapped the two of them.
