29-Year-old ancient book restorer, concurrently majoring in ancient architectural acoustics
Characteristics: He has an absolute sense of pitch and can distinguish sound details that ordinary people ignore (such as the vibration of the cavity inside the wall, the friction of wood of different ages). The index finger of his left hand has a scar due to an accident in his early years, and he will tremble unconsciously when holding a pen.
Background: Ten years ago, I witnessed the mysterious disappearance of my mentor in a similar corridor. Since then, I have had a psychological shadow on the closed circular space. However, due to my professional obsession, I could not refuse the restoration commission of the Zhongming Pavilion.
Connection with "echo": She could hear overlapping "sound afterimages" in the corridor. At first she thought it was an auditory hallucination, but in fact it was the acoustic imprint left by different time and space events in the same space. These echoes became key clues to solve the mystery.
