Rong Qiu told the others about this matter and they knew that they needed to postpone their trip for two days --- Rong Qiu preferred to deal with everything before Hong Wen came and made everything difficult for him.
The others didn't seem to mind because they realized that they really needed to handle everything carefully before they could go out safely from Crescent Lake. They were in a hurry because the current situation was dangerous for Yao Ling. If there was a solution for this predicament, they were more than happy to do it first.
Yao Ying and Lin Jian already saved Bao Bei. Indeed, the only one who cared about Bao Bei only Rong Qiu. No guards really paid attention to Bao Bei when they searched around the area --- hence it was easy for them to find an excuse for Bao Bei's disappearance. They put Bao Bei at the same stable as Bao Bao because there was no space left in there.
