Chapter 218: They had already escaped.

Watching the ambulance leave, the security guard was also dumbfounded. He looked at Xiao Yunshen and said, "Who are you? You are not the police. What are you..."

Xiao Yunshen took out his ID and said, "We are special Action team, please cooperate with our investigation."

As he said that, he asked his men to start investigating the building, and at the same time went to the security room to investigate the surveillance.

On Saturday night, the school does not arrange late self-study, so after school on Saturday, there will be no one in the teaching building.

Lu Yuebai asked, "Will someone come in while school is out?"

The security guard said, "If they are people from outside the school, they will definitely not be able to come in. We all need to register when we come in. No one from outside the school came in during the school break today." "

Xiao Yunshen said, "What if they are wearing school uniforms?"

This stopped the security guard. After all, they were wary of people outside the school. If someone sneaked in, it would be difficult to deal with it. There were people outside the school last time. Someone came in disguised as a student from the high school attached to the school.

In the surveillance video, after all the students left, the teachers also left one after another. After that, no one came for a long time.

Lu Yuebai said, "That boy probably didn't leave after school, but stayed at school."

Xiao Yunshen nodded, "That man may have known those people, so he stayed, and then those people used him to attract Shen Chutang to the scene."

There is no surveillance on the rooftop, and the surveillance on the stairs to the rooftop has been destroyed. No one knows who has been up there.

But there are surveillance cameras everywhere in the teaching building, and it is impossible for them to avoid every surveillance camera.

Lu Yuebai pointed to a place, "Look, there are a pair of shoes here!"

These people are probably internal personnel of the school who are familiar with school surveillance. Otherwise, how could they avoid every surveillance perfectly?

After discovering a pair of shoes, Lu Yuebai kept up his efforts and found another piece of clothing, "On the third floor. When my brother went up, they had already hid on the third floor!"

Because it was dark, the surveillance was a bit blurry. .

Xiao Yunshen's people checked all the classrooms and found no one there.

They have escaped.

Lu Yuebai and Xiao Yunshen sat in front of the surveillance camera together. They could only check some news from here.

Xiao Yunshen controlled the mouse, "Where is the back door of your school?"

The security guard explained, "We do not open the back door. It is just over the north gate. Students all go through the east door."

Lu Yuebai interjected, "Which school does not have a student? It's a place where people often break through the wall. Since that person didn't go through the east gate, he must have climbed over the wall.

"I really don't know," the security guard said

half an hour later. Looking at the surveillance camera, "Look, here!"

Xiao Yunshen stretched his head to see, "What?"

"Human!"

"?"

Lu Yuebai went crazy, "Didn't you see the reflection? There is a reflection here. They must have come from here. Let’s go!”

It must be said that Lu Yuebai was very careful.

Perhaps it was because he had been sick before and was unable to do strenuous exercise and had little entertainment, so he was more careful than others when it came to reading and checking information.

Lu Beiqin would occasionally give him some puzzle books to play with, and he could often see the problems in the patterns at a glance.

The ground was bumpy due to rain, and the shadows on the water were indistinguishable at all, but there was a patch of white where the water had accumulated.

This white color is probably from the school uniform!

The two people immediately came to the place where the surveillance found them, walked forward along the line, and climbed over the wall to find a snack street.

Xiao Yunshen put his hand on Lu Yuebai's shoulder and said, "You have made a meritorious service."

There were many surveillance cameras on the snack street, so they would definitely be able to take pictures.

At this time, the hospital.

Shen Chutang was sent for rescue, while Yan Ruyu drank a lot of sleeping pills and needed gastric lavage.

The hospital notified Yan Ruyu's family, and soon Yan Feng and Kuang Shuhua came with anxious faces.

"What's going on? Why do you need gastric lavage when everything is fine?"

Lu Beiqin didn't say anything, just looked at the operating room silently.

Yan Feng asked his wife to calm down and wait for notification.

At this time, the door of the operating room opened. Lu Beiqin's eyes flashed. Just as he was about to go up, he saw the nurse running away. "How is the situation inside?"

"The patient is still undergoing surgery. Don't worry. There are not enough blood packs in the operating room." , I'll go to the warehouse to send some blood."

Lu Beiqin nodded stiffly and continued to look at the operating room.

Yan Feng had a very good impression of Teacher Shen, and felt regretful at this time, "This is really sinful."

Kuang Shuhua's eyes turned red with worry, "What on earth is going on? Why should my son go when he is fine? " She's had her stomach evacuated, aren't you..."

Yan Feng hurriedly covered his wife's mouth, "Don't talk nonsense!"

Lu Bei and Qin Sen looked at her coldly, "She doesn't have to go to school today, it was your son who gave it to her. She just went there to send a message. Within half an hour, she was pushed down from the fifth floor. You ask me? "

She was pushed downstairs? " !

In an instant, Kuang Shuhua and Yan Feng felt chills running down their spines.
