As Ye Chen got closer and closer to the wall opposite, the panic in the eyes of the man with the stubbly beard grew more intense.
Zhou Susu and the other officers also noticed the change in the man's expression, and the gloom in their hearts disappeared.
Ye Chen arrived at the wall and knocked on it with his fist.
The man with the stubbly beard turned from arrogant to terrified upon seeing Ye Chen's actions.
Seeing Ye Chen forcefully striking the wall with the sharp end of his dagger, the man immediately hung his head low.
Ye Chen used the dagger to dig out a small hole in the wall and then took out a black USB drive from it.
Zhou Susu's face lit up with excitement upon seeing the USB in Ye Chen's hand.
She said to the officer beside her, "Little Li, quickly go to the car and bring over the laptop."
The young officer named Li received the order and hurried out of the room towards the police car.
