After Lin Fei entered, he found the room to be very spacious, much better than the average good room.
Lin Feng came to the desk and sat down, Lin Fei followed, and saw that there was a computer and a pile of electronic devices on the desk.
Lin Fei brought over a stool to sit down, and Lin Feng took out a little glass box and placed it in front of Lin Fei. Lin Fei saw nothing at first glance but after looking carefully again, he barely made out two tiny chips lying inside the glass box.
"One of these is a location tracker and the other is an eavesdropping device, which can be located through an app I've specifically developed for the phone. Hand me your phone."
Lin Fei pulled out his phone and handed it over to Lin Feng.
Lin Feng took it, connected it to the computer with a data cable, and began installing a special app on Lin Fei's phone.
