There were four people participating in the advanced exam. The four of them looked to be of an old age, and Yun Feng was obviously too young.
"Not a bad to have someone new here. The exam is about to begin." Another teacher spoke. There were only a few spots in the small space. Yun Feng picked one. The four teachers would see her no matter where she was, forming an observation angle of 360 degrees.
"Are we starting?" A voice with a smile sounded. The secret door on the side opened and a few people walked in. The person in the lead was a middle-aged man who looked more amiable. The four supervising teachers immediately stood up and replied very respectfully. They even prepared a chair for their master. Yun Feng looked at them and understood that this person should be someone from the headquarters of the pharmacists.
