NEED A FAVOR

After taking a nap, Mu Lan and Ru Xin went to the kitchen and saw that the lunch was ready for them. As for the cook, he was nowhere to be found. Ru Xin was very skeptical about this. His castle had high security and no one would be able to come here without him noticing. If a person wanted to invade here uninvited, a siren would have rung. However, when the doctor in blue clothes came and attacked him, nothing happened. It made him wonder if that doctor was some kind of terrorist. However, after being treated by him, Ru Xin couldn't think bad about it. Moreover, that doctor came for him Little Lan and she confirmed that she grew up with him. She was a person with a good heart and the person who taught her everything couldn't be a bad person; that's what Ru Xin believed. 

He asked Mu Lan, "Where did your doctor go?"

Mu Lan truthfully answered, "He didn't sleep well for the past few days. So, I told him to sleep. I believe we will find him in the clinic."
