The last time Ms. Lin was on surveillance was around 10:30 a.m. on Saturday. There are not many students who stay on campus on weekends, and generally only junior high school students who need to take entrance exams will apply to stay in school, and these students do not have time to wander around the school. So, they quickly found her traces in the surveillance.

I saw her wearing a school uniform and carrying a white leather backpack out of the student dormitory and walking towards the southwest of the school. The southwest corner is the school's playground and cafeteria, although there are surveillance along the way, but the school is more arbitrary when setting up the camera layout, without considering how to minimize blind spots, there is a lot of white space between stepping out of one camera field and entering another camera view.

"She must have gone in the direction of the playground." After observing the environment and terrain of the school on the spot, and comparing the direction of travel of Lin Xuerou in the surveillance video, the police came to a conclusion.

But there's nothing over there. In addition to a plastic runway and the green trees planted around the runway, it is a fence enclosed with iron fences and bricks. What exactly is she doing here? How did it disappear?

asked a few classmates who were good friends with Lin Xuerou on weekdays, and they didn't know what she stayed at school last weekend for.

Wen Qiao looked at the list of student dormitories, and a familiar name came into view, Gao Caiqin was not only Lin Xuerou's classmate, but also lived in the same dormitory as her.

When he came to the school, Ling Ling was a little surprised to see him, and blurted out, "Why are you here?" ”

Wen Qiao didn't answer, but said directly: "Do you know that Gao Liqun's daughter is in the same class as the missing girl, and even lives in the same dormitory?" ”

Ling Ling let out an "ah", and then said, "It seems to be...... What's wrong with that? Could it be that she had something to do with the girl's disappearance? ”

Wen Qiao just said lightly: "Wouldn't you know if you go and ask?" ”

Although there was one less person in the class, everyone else still had to attend the class normally. They took advantage of the gap after class to call Gao Caiqin out.

When Gao Caiqin saw that it was him, a hint of joy suddenly flashed on her cold face, but after seeing the person following behind him, she was immediately disappointed: "What about Sister Liu?" Why didn't she come with you? ”

Ling Ling also saw the change in her face, and instantly became unhappy: "She's not a policeman, why did she come?" ”

Wen Qiao heard Gao Caiqin suddenly mention Liu Mengwei, and his heart suddenly moved: "Have you been able to see her often recently?" What has she been doing lately? ”

When she was in the hospital last time, in order to appease Wang Huaying's emotions, Liu Mengwei offered to provide free psychological counseling for her two children to help them grow up healthily. Maybe it's because Liu Mengwei's attitude of admitting her mistakes is particularly sincere, or maybe it's because of this promise, Wang Huaying didn't continue to hold her accountable in the end.

Hearing Wen Qiao's question, Ling Ling and Gao Caiqin were stunned, but the thoughts in their hearts were completely different.

Ling Ling was surprised that Wen Qiao, who had never asked about the world, cared about a person so straightforwardly, and couldn't help but feel a strange emotion in his heart.

And Gao Caiqin smiled meaningfully: "I have already seen it, you two denied it last time." So, you just want to pursue Sister Liu, right? ”

Wen Qiao didn't expect that her question just now would be misinterpreted by her like this, so she lowered her face and interrupted her seriously: "What are you talking nonsense?" ”

"Wow! Uncle, you're so old, won't you be embarrassed? Gao Caiqin covered her mouth and laughed.

Wen Qiao couldn't help her, sighed helplessly, and simply stopped asking Liu Mengwei about it. "Then tell me about you."

"Me? What's wrong with me? Gao Caiqin showed a puzzled expression.

"Isn't Lin Xuerou your roommate?" Ling Ling really couldn't stand the fact that the two of them didn't talk about the topic for a long time, so he interjected impatiently: "The two of you usually have a lot of contact, do you have any clues about her disappearance?" ”

Hearing this, Gao Caiqin just pouted: "What clues can I have?" I'm not her mother, staring at her all day long. ”

Ling Ling also saw the clue: "The relationship between the two of you is not very good." ”

"Yes." Gao Caiqin said angrily: "So I basically don't know anything about her, so you better ask someone else." ”

Ling Ling was a little angry at her indifferent attitude: "She is your classmate after all, she is missing, aren't you worried at all?" ”

"What's the use of worrying about me? Am I worried I'll be able to find her? After all, it's not that you police are useless and can't find anyone. Gao Caiqin's teeth were sharp, and Ling Ling's teeth were speechless.

"Alright." Wen Qiao interrupted the bickering between the two: "However, after all, you live with her and have more opportunities to get in touch, so you may be able to think of some details to help us find her." ”

"We found her missing and headed in the direction of the school playground, do you know why she went there? Have you ever heard her say anything about it? ”

"Playground?" Gao Caiqin muttered, as if she remembered something.

"I don't know what Lin Xuerou is doing in the playground, but when it comes to the playground of our school, I really encountered something over there."

Ling Ling came to his senses and hurriedly asked, "What is it?" ”

"One night I couldn't sleep, so I wandered around the school. When I walked to the playground, I suddenly heard someone talking on the playground near the fence, so I hid and peeked, wondering what those people were doing hiding here so late. But after a while, there was no movement over there. Then, I walked over to look and saw that there was no one left. ”

"Can't it be a run over the wall?" Ling Ling guessed.

"But there's an electronic fence on that wall in our school." Gao Caiqin retorted.

"Maybe it's from the other exit." Ling Ling said again.

"If that's the case, I'll see it." Gao Caiqin said very firmly.

"So, you think those guys disappeared out of thin air from your school's playground, like...... Just like Lin Xuerou. Ling Ling's face changed slightly.

But Gao Caiqin just shrugged: "I don't know about this." It's only when you mentioned 'playground' and 'disappearance' that I remembered it, and I had almost forgotten about it. ”

Ling Ling had no clue and looked at Wen Qiao as if asking for advice.

"Do you remember where they disappeared?" Wen Qiao asked.

"Hmm...... I only remember a general direction, after all, there were no lights over there, and I couldn't see anything clearly when it was dark at night. ”

"Lead the way."

The three of them were about to go to the direction of the playground, but at this time, Wen Qiao suddenly stopped. He stopped Gao Caiqin: "Don't you have to go to class later?" ”

Gao Caiqin woke up like a dream: "Oh, I almost forgot if you didn't say it!" That's it, Uncle Policeman, you can help me ask our teacher for a leave, anyway, I don't want to go to class, so let me follow you to solve the case! ”

Wen Qiao looked at her steadily, and his cold eyes could see the bottom of people's hearts: "I heard that your academic performance was very good in the past, why are you like this now?" ”

Gao Caiqin had an expression of "why are you here again", and said impatiently: "Uncle policeman, you are too lenient!" My mom doesn't care about my grades, what the hell do you care? Aren't we going to investigate? Just now, you were still in a hurry to find Lin Xuerou, what's the matter? Aren't you in a hurry now? ”

Ling Ling was also a little surprised, she didn't understand why Wen Qiao suddenly cared about other people's academic performance.

"Have you never felt anything wrong yourself?" Wen Qiao does not relent.

"Something is wrong? What's wrong? I don't understand what you're talking about. Gao Caiqin's eyes dodged, and anyone with a discerning eye could see that she was not telling the truth.

Wen Qiao didn't press her anymore, because it suddenly occurred to him that he couldn't ask from her, but there must be someone who already knew the answer. Even if faced with a sudden accident, even if someone is forced into a corner, that person can smoothly turn the danger into a disaster, and even be able to turn the customer into the first, grasp the initiative, and turn the disadvantage into an advantage.

After becoming the family psychologist of the Gao family, what else is there that cannot be known? The password that Gao Liqun left on his two children, no matter what it is, the person who can solve it the most must be her.
