Under Apothecary Mu's lead, it didn't take long for them to arrive at a room.
"Please report that Apothecary Mu Yang requests for an audience!"
Apothecary Mu clasped his fist toward the apprentice guarding by the door.
"Yes!"
Knowing the other party's identity, the apprentice immediately went in to report his presence. A moment later, however, he returned with an apologetic look on his face. "Teacher is currently discussing some important matters with an esteemed guest, so he isn't free at the moment. Apothecary Mu, you should return tomorrow!"
"This matter is urgent. I really can't wait until tomorrow..."
Apothecary Mu shook his head. "I hope that you can relay another message for me. Just say that I have something urgent that I require Apothecary Hong’s help on!"
