"This is my contact information.. I mean, if you find any traces of Niu Sidun, you can contact me at any time."
Chen Fei'er wrote a phone number on the paper and handed it over.
Ye Feng glanced at it and threw it into the trash can.
"You... This matter concerns your safety. I hope you can take it seriously."
Cheng Fei'er frowned when she saw his actions.
"I've already memorized it. Do you want me to repeat it to you?" Ye Feng asked with a smile.
With his current memory, it was easy for him to remember a phone number.
"Alright, that's all I have to say."
Cheng Fei'er didn't say anything else.
Ye Feng immediately stood up and was about to leave.
At this moment, his phone suddenly rang.
The caller ID showed that it was an unfamiliar number.
He frowned, but still picked up.
At the same time, he pressed the recording button.
