Only those who have undergone long-term training would unconsciously reveal such unique characteristics of a soldier in their gestures and actions.
Rong Yan did not let her guard down because of this, and instead cautiously moved slightly backward, her eyes serene, "Why should I believe you?"
The two of them seemed to have anticipated her question and, following the instructions they had been given earlier, handed a mobile phone to Rong Yan.
Rong Yan hesitated for just a second before taking the mobile phone.
There was only one phone number displayed on the screen.
Moreover, the phone number was very mysterious, unlike ordinary phone numbers, with letters included among the digits.
Rong Yan was no fool and realized that they had given her the phone for her to call this number. After hesitating for a few seconds, she steeled herself and dialed it.
"Beep—"
The husky beeping noise from the phone did not last long before it was picked up.
"Hello."
