Liu Shimei shook her head. "I'm just an apprentice under Doctor Du Gong. I haven't taken him as my Master yet. I learned everything myself."
"How long have you been in the Zheng Medical Hall?" asked the old man.
"Only recently." Liu Shimei looked at him and smiled. "You're not from the registry department, are you?"
The old man did not insist on asking any more questions. He took out a silver ingot from his pocket and placed it on the table. "With your medical skills, this doctor from the Zheng Medical Hall is not worthy of being your Master. It's better not to acknowledge him as your Master, lest you ruin your future! You have a good heart. You don't have to look for the rest. This old man will come to you tomorrow to get the medicine!"
With that, he turned around and left.
Xu Xian was surprised to see him walk out of the door. He turned to Liu Shimei and asked, "Miss Zhi Liu, what does that old man mean?"
