Bai Jingfei was still pretty darn confused. She wasn't sure of what exactly she was supposed to be doing, but she knew that heavenly doctor Ming was dumping his dirty work on her.
There was no other good reason for him to act like he was dying if he wasn't.
After so many months of working with Ladder under heavenly doctor Ming's tutelage, she knew very well, how lazy heavenly doctor Ming was. He would not move unless absolutely necessary, or unless there was some great benefit out of him moving.
More likely than not, he was just dumping some work he had promised to do, on her, because he was drunk and hungover and lazy.
It was completely plausible.
There were drunkards, mad drunkards and then there was heavenly doctor Ming.
