Tape recorder had its popularity in the eighties and nineties, but with the advent of internet, it had slowly become obsolete. Perhaps to preserve the feel of the bygone era, Tian Teng Medical School had placed many antiques inside this room, and the most conspicuous was the tape recorder and an old-fashioned flashlight.
Chen Ge was reminded of a horror flick he had seen a long time ago. The recorder would play on its own every midnight, and those who heard it would die a horrible death.
Is this just a prop? Chen Ge completely ignored the 'dead body' that was collapsed on the table. He walked past it to head for the bookshelf. When he was one meter away from the recorder, the play button pressed down on its own.
