Lin Ying pushed open the door of the Academic Affairs Office, probably because the police had been visiting Wei University recently, and she was already familiar with the teachers.

Director Xu of the Academic Affairs Office saw her and stood up without the slightest surprise.

"Captain Lin, you're here again. Hey, Mr. Shen, I just heard that you have been discharged from the hospital, what a blessing in misfortune. ”

"Xu, can you help me look at Du Wanqian's course selection schedule this year?"

"No problem, I'll take you to Xiao Chao, she's in charge of this."

I also followed behind in a daze, and Director Xu looked back at me with a meaningful smile on his face.

Probably because I often go to Wei University to look for Shen Yu, so although I haven't greeted this Director Xu before, he may have known me for a long time.

Director Xu led us out of the hut and into a large office full of cubicles. I know Xiao Chao from the Academic Affairs Office, who graduated from graduate school the year before last.

Director Xu explained his intentions, and Xiao Chao brought up Du Wanqian's course selection list in front of the computer three times and two times.

"From what I know about Du Wanqian, she shouldn't be there for every class—can you help me check her attendance records?" Shen Yu said.

"This—" Xiao Chao looked at Director Xu a little embarrassed.

"What? Having a hard time? Lin Ying walked over and asked.

Xiao Chao lowered his head and didn't speak, Director Xu sighed and said: "You all know that Du Wanqian's child loves to make trouble, so the teachers don't want to provoke her, she - basically whether she goes to class or not, she will be recorded as full attendance." ”

"Isn't there anyone but me who truthfully records her attendance?" Shen Yu looked at Director Xu and asked.

"That's right."

"How can I see her real attendance record?"

"I guess I can only adjust the classroom monitoring - you know, the attendance records in the education system are actually entered according to the data submitted by the teachers."

Lin Ying frowned: "But there are so many classroom monitoring records, do you want to check one class after another?" ”

"No, you don't." Shen Yu shook his head and said, "Because she hasn't taken a few classes at all, at least she never comes to my classes, we just need to follow the class schedule to find out which classes she is willing to attend." ”

The surveillance records are all in the Security Section, and Director Xu took us to the Security Section again.

"Start with the required courses or from the elective courses?" The officer of the Security Section asked.

"Electives." Shen Yu thought for a while and said.

The officer began to retrieve the control logs. Elective courses are generally held in the lecture hall, and the picture quality is not very clear, and it is really not easy to find Du Wanqian's head from the crowd.

Shen Yu turned to look at me: "Do you remember what Du Wanqian looks like?" ”

"I remember, there are photos in the dossier, and I have seen them a hundred times." I pointed to my head and said, "It's been in my head for a long time." ”

"Then you come and find it." She said to me.

I nodded, and stood right in front of the surveillance screen.

Although I have never seen Du Wanqian alive, I have seen more than a dozen photos of various angles in the dossier, and I still have her appearance and characteristics in my mind - although her hairstyle is constantly changing, her head shape is round, the edges above her ears are pointed, and her chin should be neat, slender and prominent.

And her cheekbones are relatively high, especially when viewed from the side.

Judging by the hairstyle, she seems to prefer to have short hair, and girls with short hair generally have their ears exposed.

I had an idea for a moment.

Just like Shen Yu needs logic to solve a case, I also need a logic to find someone according to my memory.

Since I don't have time to go through the dozens of students in each class head by head, I might as well use the "focus method" to narrow down the scope layer by layer - first find the girls with short hair, pointed ears and long chins, and then eliminate them one by one in a small area, and I have a memorable memory, even if I miss a picture, I can always call it up from my mind and superimpose it into a new image.

"Let's get started." I said with a deep breath.

Several pairs of eyes were staring at me in unison, and although I was a little nervous, I tried to keep my attention on the screen.

"I didn't have this class." I glanced at it and said.

"This lesson—no, never."

"Yes."

"Next lesson."

“…… Pass. ”

"Wait! Stop, there is her in this class, the one who sleeps on the desk in the last row, and the third on the right. ”

Xiao Yu took a closer look, then looked at the photo in his hand, looked at me in surprise and said, "It's true, Teacher Yan's efficiency is amazing." ”

Lin Ying also looked at me with strange eyes, and the expression seemed to say: Why didn't I know that you still had this ability?

"What kind of class is this?" Shen Yu asked.

"Wait a minute." Xiao Chao glanced at it and said, "It's an elective course, Western art appreciation." ”

Shen Yu nodded: "Next class." ”

"No, never." I continued to talk as I watched.

We were busy for a full hour and a half, and watched about two-thirds of Du Wanqian's classes throughout the semester, and the summary is that in addition to sleeping in the Western art appreciation class, the only class that can be seen and must be attended every time is the elective course "Folklore".

"Did An Yue take this course?" Shen Yu asked.

"Nope." Xiao Chao replied.

"Yan Zhu, do you remember some of Du Wanqian's actions in class?"

I nodded.

"What's her most frequent movement?"

"The movements are different in each class, but she always seems to be looking at a certain aspect in class and not moving."

"Bring up a video of a lesson."

The officer's hands and feet quickly switched to a certain picture of Du Wanqian's class, and she really held her cheeks and tilted her head, and kept looking diagonally ahead.

Shen Yu walked to the screen and bent down, her fingers slid on the screen, following Du Wanqian's line of sight to trace a line, we were surprised to see that the end of the line was a handsome boy on the side.

"One more class."

The director quickly called up another video of "folklore", and sure enough, this time Du Wanqian's eyes looked to the left front, and the end of his sight was still the boy.

Shen Yu raised his head to look at all of us, and then smiled.

"What's the boy's name? Can you help find out what connection he has with An Yue? ”

"Wait a minute." Xiao Chao simply opened the laptop she bought, and she also quickly retrieved the information of the course selectors, "It should be Ran Zijin, a junior in the School of Environmental Engineering, he and An Yue are not in the same department, but the two of them took the elective course 'Game and Society'." ”

"Can you help me pull up one of these lessons?"

The director typed in the name of the course, opened the folders, and finally selected a video file and clicked on it.

The video began to play slowly, and when Ran Zijin's back appeared in the video, we were all stunned.

Because his sitting posture is exactly the same as Du Wanqian's - tilting his head and looking straight ahead stupidly, and the person he stares at from time to time is none other than An Yue!

......

Ran Zijin returned to the semi-basement he rented a little dejected.

In fact, he has been secretly paying attention to the movements of the police.

A few days ago, the police officers inquired about Du Wanqian's connection to An Yue's death, but they did not find him, after all, he had no direct contact with the two girls on the surface.

But what everyone didn't know was that he had actually liked the girl named An Yue for a long time.

Because she is the kind of lover in Ran Zijin's dreams.
