Su Zhan's fingers repeatedly rubbed the words on the back of the photo, feeling a bad feeling in his heart. He took out his mobile phone and called Fang Xuyang, "Xu Yang, check where Song Yingxing is." "Master, I just wanted to call you, Miss Song... She received a mission from Doctors Without Borders and went to Afghanistan." Fang Xuyang finished the report cautiously, and before Su Zhan could respond, he heard a loud noise, and then a busy signal. Su Zhan smashed his cell phone. Because he was out of breath, he put his hand on the table and coughed violently. The fire in his heart seemed to start a prairie fire. He picked up the photo and looked at him and her in school uniforms in the photo. He lowered his head and read a book. She sat opposite him and looked at him over the book.
