As if to respond to the instructor's voice, a riotous noise echoed from outside. It sounded like footsteps, like people were talking. Clearly, the person they were expecting was quite close by.
Then came a knock on the door. The instructor had barely said "come in" before a teacher around fifty years old entered, "Why are you not ready yet? They're all waiting downstairs."
Lu Weixi, having studied here for seven years, recognized him right away. He was a professor in the department of architectural design and had once mentored Qin Zhigu during his undergraduate thesis.
She advanced, "Professor Zhang."
Professor Zhang wasn't oblivious to another person's presence in the room, but upon noticing that they were a student, he didn't pay much attention. Only after hearing her greet him did he take a good look at her face.
