Grey Wolf got the information. Yun Xi's phone was near the alley.
Once he received that, Qi Yuan was able to find Yun Xi's phone in a trash can.
Qi Yuan's heart sank when he realized that her phone was there, but she wasn't.
Taking a deep breath, he barked orders at the person on the other end of the phone in a serious tone, "Grey Wolf, investigate all the surveillance cameras near this address right away! Right this minute!"
"As fast as possible." Grey Wolf answered, and soon the sound of this typing on his keyboard could be heard from his end of the call.
In three minutes, Grey Wolf had hacked into the surveillance system of a nearby camera. He relayed the information.
