Even though a woman answered the call, Wang Yu still decided to initiate location tracking on the cell phone number. As for the possibility of Gao Xiaoyong lying, he had considered it, but he felt the likelihood was almost nil.
Both Qin Tian and himself had ruled out Gao Xiaoyong as a suspect, believing it was impossible for him to be a spy. Even after hearing Qin Tian's report, he had come to the same conclusion. He could doubt his own judgment, but he wouldn't question the observational skills of Qin Tian and Qin Xuyang.
Qin Xuyang had been a Dragon Bodyguard, someone responsible for the safety of national leaders during their travels. His observation skills were naturally beyond doubt; otherwise, he wouldn't have become a Dragon Bodyguard. And Qin Tian's skills were even sharper than Qin Xuyang's.
