Lin Yi walked straight to Fang Qing's room and knocked on the door.
"Please come in."
Soon, Lin Yi heard Fang Qing's voice from the room. She pushed the door open and realized that the door was not closed.
It was normal that the door was not closed. After all, she was a Saint, and no one would dare to find trouble with her.
Fang Qing saw Lin Yi walking in and asked,""How's your stay here? Are you satisfied with the food?"
"Very good. This is the best meal we've had in more than a month."
Lin Yi said with a smile as she sat down next to Fang Qing.
It was only then that she realized that Fang Qing was reading a book.
However, the book that Fang Qing was reading was different from ordinary books. It was thread-bound and the paper was a little yellow. One look and you could tell that it was quite old.
"Tuibei diagram?"
Lin Yi asked.
"Yes."
