Ling Zhenfei knew the people opposite him were lying; their goal was to exchange Zhuo Yue for ransom, so it was impossible for them to release Zhuo Yue.
"Fine, but I need to hear my girlfriend's voice first. What if I go there and can't see my girlfriend?" Ling Zhenfei did this just to confirm whether Zhuo Yue was still alive.
"You're pretty clever, kid. Then listen carefully; I'll let her say a word to you."
After the person finished speaking, they heard Zhuo Yue cry out loudly: "Don't worry about me, don't come looking for me..."
Zhuo Yue shouted once before someone covered her mouth. Cries of Zhuo Yue came through the phone after she'd apparently been hit by the person on the other end.
"How about it, friend? You heard her, right? I didn't lie to you. Hurry up and bring me the memory card. As long as the item is fine, I'll release your girlfriend. But if you're too late, you know the consequences."
