Not long after, the detector made a notification sound. Xu Xiang looked at the screen, then squatted down, and picked up a strand of hair from the ground. She looked at the hair for a while, then turned to look at Mu Yucheng.
Seeing that he was still looking around seriously, she said, "Mu Yucheng, as long as we can track them down, that is enough, right?"
"Mhm." He answered while carefully touching the wall of the building.
After getting his answer, Xu Xiang turned off the detector and the small screen, then put them back in her space. She then took out a tracking device from her space. After turning on the device, she placed the strand of hair into a small box located under the device, and tapped the device screen a few times.
After a few seconds, the device beeps and a map appears on the screen with a red line on it. She looked up from the screen and said, "Mu Yucheng, I found their location."
