If Yun Jian had not covered Mu Shuang's mouth in time, Yang and Mu Rou who sneaked by the hallway outside of the bedroom would definitely have heard Mu Shuang talking. They might withdraw directly then.
Since they did not hear anyone talking now, though, they assumed that Yun Jian, Mu Ying and Mu Shuang had really fallen asleep.
As Yun Jian kept a palm over Mu Shuang's mouth, the latter did not make any sound obediently and had even slowed down her breathing.
For about 30 seconds after that, Yang nor Mu Rou could be heard from the hallway. Yun Jian squinted, knowing that the two of them must have their ears against the bedroom door to listen if the three of them inside were actually sleeping.
Mu Shuang blinked. Although she had no idea what was going on, she was willing to follow Yun Jian's instruction.
