Seeing the display on the screen of the mobile phone, Jian Ran's heart skipped a beat, and her right hand holding the mobile phone trembled slightly. She took a deep breath and answered: "Hello, hello!"

The other end of the phone was still silent as last time. Jian Ran tried to hear what sounds could be heard around him, but it was so quiet that not even the slightest sound of wind could be heard.

Jian Ran stood at the gate of the hospital and looked around. There were people coming and going around. In the distance was a main road of the city, with constant traffic, and she couldn't find any suspicious people.
