In the dark room, Leng Feng and the others were lying on the large bed sleeping soundly.
Sima You Yue had prescribed something in their medicine pills that would calm their nerves and induce sleep, so that they would recover better.
Because of the efficacy of the medicine, Leng Feng and the others were unable to defend themselves against danger. If someone had come inside at this moment, it would be very easy to do something to them.
In order to protect their safety, she had set up a spirit barrier outside the courtyard where they were staying. If someone were to destroy the spirit barrier, she would know and she could rush back to save them.
When she put up the spirit barrier, she had spoken to the innkeeper as it would affect his business temporarily after all. She hoped that he would be able to help look out for them.
