Chapter 849 Unable to Detect

• Helpless, the technicians had no choice but to take Ning Feng's phone down first and then use their own phones to test whether it was a device malfunction.
• However, as soon as their phones were pressed against the device, the red light on the device instantly went out, and there was no sound at all. It proved that the problem was with Ning Feng's phone.
• Realizing this, the technicians couldn't help but turn to look at Qin Jiang and Ning Feng, their faces showing an expression of wanting to speak but stopping themselves.
