Zhao Xiaoyan's chuckle rang out in the small classroom, and everyone looked at Zhao Xiaoyan quietly. Zhao Xiaoyan smiled softly, but in the end she couldn't help laughing out loud. The classroom was quiet, and no one spoke on the other end of the phone. Only Zhao Xiaoyan's laughter could be heard in the classroom.

"Are you crazy?" Teacher Zhao squinted at Zhao Xiaoyan: "Why are you laughing when Wang Yedan is missing?"

But Zhao Xiaoyan ignored the crowd and kept laughing. It seemed that the news made her happy.

"I don't know why, I just wanted to laugh." Zhao Xiaoyan smiled and said, "Wang Yedan disappeared, I said that God will not give all the benefits to one person, Wang Yedan is missing, haha."

Shao Lao sighed, waved his hand and said, "Now is not the time to talk about this, go to the surveillance immediately."

Director Zhang also heard Shao Lao's words over the phone. Shao Lao's serious tone made Director Zhang think that Shao Lao was not joking. Director Zhang also realized the seriousness of the problem, and he said, "Comrade police, Mr. Zhao knows where the school's computer room is. Let's go to that place immediately."

Shao Lao nodded.

Teacher Zhao led the crowd out, and turned around and said to Zhao Xiaoyan, "Go back and write a five-thousand-word review for me, and I'll settle your account with you later."

Having said that, Mr. Zhao hurriedly brought everyone to the computer room. In the computer room, Director Zhang also arrived with Wang Kun and his wife.

Wang Kun frowned and stood at the door, still relatively calm, while his wife was pulling his arm tightly, looking very worried.

"Is Wang Yedan's cell phone turned off?" Shao Lao asked straight to the point.

Mrs. Wang nodded, looked down at her mobile phone and said, "Yes, just now my husband and Director Zhang talked about school investment. They talked about the present from the morning, and also talked about Wang Yedan's future at school. After the talk, we called Ye Dan, but it turned off. I called several times in succession, but it was also turned off, so I called Mr. Zhao. I called another one just now, but it was still turned off. "

Wang Kun asked: "How can you say that Ye Dan is missing? If there is no clue, the police will not say such unsure things."

As a business owner, Wang Kun has a very sharp mind.

Mr. Shao sat in the chair: "Yes, the reason behind Lu Ben's suicide has nothing to do with your daughter, but the incident happened because of your daughter. A lively and cheerful college student suddenly committed suicide. There may be some unknown reasons behind it."

"This reason is probably also the reason why my daughter disappeared." Wang Kun said.

"Yes." Shao Lao replied.

"It's here." The school security called up the morning surveillance records, which began when Wang Yedan left the dedicated self-study classroom for Class 941.

But Jiang He opened his mouth and said, "Move forward, starting from the moment Wang Yedan came to the school."

The security guard glanced at Jiang He and said, "You criminal policeman doesn't have as much brains as mine. It depends on when this girl disappeared, not where she appeared last, and who was the last person to see her. That's alright, why watch it two hours in advance, isn't it superfluous?"

Jiang He shook his head and said, "You just think it's good to find the time when she disappeared, and what we want to investigate is who caused her disappearance, starting from six o'clock in the morning."

The security guard mumbled a few words and began to look for it. This is a very boring and uninteresting job, and it is no wonder that the security guard is impatient.

But Jiang He didn't take his eyes off the computer screen for a moment, he said, "This is it."

"Ah?" the security guard said, "Where?"

Jiang He pointed to the far right of the screen. It was an exposed arm. He was wearing a black windbreaker with a small white metal button on it.

"Can you see one arm?" The security guard clearly didn't believe it.

But then, the security guard couldn't close his mouth. Sure enough, when the person was completely exposed to the camera at the school gate, the security guard found that that person was indeed the person they were looking for. At that time, it was about seven in the morning. Wang Yedan appeared in the video alone. She hardly stopped and walked straight to the Wenke Building.

At around 7:10, Wang Yedan was already waiting at the door of the 601 office. At that time, Shao Lao and others were in the 6 boys' dormitory, listening to Zhang Jun and others' views on Wang Yedan. Wang Yedan waited at the door, the corridor was empty and dimly lit.

Wang Yedan sometimes paced the corridor, and sometimes looked at the slogan on the wall.

Then, she put her hand into her pocket, and when she took out her mobile phone, a note appeared in Wang Yedan's hand. Wang Yedan opened the piece of paper, which seemed to have some words written on it. She looked at it for a while, then crumpled the piece of paper into a ball and threw it into the trash can beside it.

Just because of the angle, everyone couldn't see what was written on the note.

"Have you seen this trash can?" Shao Lao said, "How often does the trash in the trash can be cleaned up?"

Director Zhang scratched his head: "I don't know this very well, I don't care about it."

"Yuan Jun, look for it immediately." Shao Lao said.

Yuan Jun didn't hesitate. Hearing Shao Lao's words, he immediately ran out to find the note.

The video on the computer screen continued to play. At half past seven, Director Zhang walked out of an office at the end of the corridor, opened the door of 601, and let Wang Yedan walk in. Immediately afterwards, Mr. Zhao and the members of the task force appeared in the corridor with a large number of students.

There is no surveillance in the office, but except for the security, everyone present knows what is going on in the office.

At eight o'clock, a large group of students left the office. They sparred happily in the corridor for a while, and left the office in a mighty manner.

At 8:20, Wang Yedan's parents came to the office, and at 8:40, the members of the task force left the office. At 8:50, Wang Yedan left the office.

After walking out of the office, Wang Yedan stood in front of the trash can and hesitated for a few minutes, looking like she was looking for something in the trash can, but after a few minutes, she still chose to leave. After leaving the office, she did not go back to the dormitory, but walked to the playground alone.

There are layers of stands on one side of the playground. She sits in the center of the stands with her head lowered, her arms wrapped around herself, and she does not move. There are not many cameras in the playground, and it is too far away from Wang Yedan. No one can see what Wang Yedan is doing, but in fact everyone knows what she is doing. She doesn't actually do anything, just sits there quietly, feeling Cold and dry wind in winter.

The west wind blew the ends of her hair, and her long hair fluttered like a small black flag.

Until about 9:30, she stood up, walked through the path alone, and came to the classroom.

In the video, I saw Mr. Zhao's exaggerated movements, but because there was no sound, I didn't know what Mr. Zhao was talking about.

At ten o'clock sharp, Wang Yedan left the classroom. Wang Yedan, who left the classroom, was not with his classmates. In the backs of his classmates, Wang Yedan walked alone, looking a bit desolate and sad. Wang Yedan wandered aimlessly on the road. Suddenly, Wang Yedan seemed to have thought of something. She seemed to have a purpose and walked towards the distance.

Wang Yedan walked to a corner of the campus. The more she went, the fewer people there were. In the end, there was hardly anyone on the road.

"What is that place?" Shao Lao asked.

"Parking lot," the security guard replied.

Wang Yedan walked straight towards the parking lot, all the way to the bottom of the parking lot.

"Wang Yedan didn't come by car." Jiang He said, "Why did you go to the parking lot?"

After saying that, Jiang He turned his head to look at Wang Kun: "You asked her to wait in the parking lot?"

Wang Kun said: "Ye Dan urged us to come early on the phone. We could hear that her tone was not very good, so we didn't have time to park the car in the underground parking lot, and just parked it downstairs in the Wenke Building."

"That's weird," Jiang He said.

The security guard switched the video to the underground parking lot in chronological order, and Wang Yedan appeared on the computer screen again. Wang Yedan seemed to be looking for something, she walked slowly into the depths of the parking lot, and then she seemed to see something and walked in one direction.

A car was parked silently, but the camera couldn't see what was going on inside the car.

Wang Yedan walked straight to the front of the car and turned on the co-pilot of the car. After that, the car started and left from the underground parking lot. He drove out of the small courtyard soon, not knowing where to go.

"Who is this person?" Wang Kun said, "Why did Ye Dan get into his car?"

For a moment, Xu Yiman thought of the rumors that Wang Yedan was being fostered. Could it be true? But if you look closely, this car is not a luxury car, just an ordinary Beijing-Jing Hyundai. Given Wang Yedan's worth, it will definitely not be cared for by someone who drives such a car.

"Don't you know each other?" Jiang He was a little surprised.

"Know what?" Xu Yiman asked subconsciously.

"This car is not someone else's, it's yours." Jiang He looked at Wang Kun.

Wang Kun frowned. He wasn't even sure, so he asked his wife beside him, "Do we have this car at home?"

Mrs. Wang carefully looked at the license plate for a few minutes before she said, "Yes, this is our car, usually driven by Ye Dan, and this license plate was made by her uncle."

Wang Kun said: "Maybe Ye Dan parked his car in the parking lot a few days ago. He didn't drive it yesterday, but he came and drove away today."

"No." Jiang He stood up, shook his head and said to the two of them, "Yesterday morning, your daughter drove to the Public Security Bureau. At that time, the school gate was closed, and no more cars could come in. And your daughter came to school. She also walked in when there was no one in the car. Besides, if there was no one in the car, she would not sit in the co-pilot."

"Continue to watch the surveillance." Shao Lao said: "I want to know when this car was parked in the parking lot."

With that said, Mr. Shao said to Xu Yiman: "Inform Captain Liu immediately, and the whole city is looking for this white Hyundai with a license plate."

Who is this mysterious driver?
