"Oh? Maybe it's all lost? Seongnam muttered to himself. At this moment, Seongnam had a flash of inspiration in his head, and suddenly remembered the postman in the morning and said excitedly: "That's right! Lin Kexin is actually a disabled child, so naturally she can't send this letter herself. It must have been taught to the teacher to send it. If Lin Kexin is not in contact with the other party for the first time, then the teacher who helped send the letter must know who the letter is sent to and where. After all, as a teacher in a school with a disability, I have to pay more attention to everything than ordinary people in my students. ”

"yes, I didn't think of anything." Zhang Mei suddenly came to her senses.

"I'm going to find the teacher who taught Lin Kexin at the beginning." After Zhang Mei finished speaking, she rushed out and threw Chengnan alone in the dormitory.

Soon after, Chengnan and Xiaogang were also taken to the hospital for examination. The results of the examination were all normal and there was no major problem.

When Chengnan and Xiaogang returned to the dormitory, Zhang Mei was already waiting for them in her dormitory.

"Officer Zhang, are you back? Did you ask what was going on? As soon as he returned to the dormitory, Chengnan saw Zhang Mei sitting in his dormitory, and Chengnan asked.

"Shoot!" Zhang Mei threw a file bag on the table, and said with a happy face: "I have investigated some clues, oh, all the details are here, you can take a look at it first, and then I will tell you." ”

Cheng Nan and Xiao Gang picked up the file bag on the table and looked down, while Zhang Mei explained: "I found the teacher who taught Lin Kexin just now, his name is Xu Ping, there are only three teachers in this school, he is the only male teacher here, under his recollection, he does know that Lin Kexin will occasionally contact a person named Xu Xin." Since Lin Kexin only wrote his name when he wrote the letter, he didn't know who this Xu Xin was, and they didn't write directly very often, so the last time we were making a record, he also forgot to tell us at this time. But because this place where Xu Xin is located is very famous, Xu Ping remembers it very clearly. ”

"What address?" Seongnam who was looking at the archives didn't forget to ask.

"University of Southern France! Nanjing's most famous university of technology. Zhang Mei said.

After speaking, Zhang Mei's tone was a little excited: "It was according to this clue that we found this Xu Xin's information." I didn't expect this Lin Kexin to really have a twin sister! ”

And Chengnan on the side couldn't help but gasp when he got to the photo on the last file and said: "It seems! ”
