Bab 493: Interrogation Training (6)

Qing Shu Lian sat down on the sofa and raised his hand, pretending to fix his hair beside his ear. A small bug was placed behind his ear and it was retrieved along with his movements just now.

It was a transmission and listening device. 

The other bugs were in the hands of Nan Hua and Feng Yu Hua. This was one of their methods of communication that was done in secret. After all, even if they met each other every day, it was not very convenient to discuss everything openly in front of other people.
