Chapter 134

Qiao Xi put her hand into her pocket and then took out a silver metal USB flash disk. "Teacher, I have something here. I want to play it to the teacher and explain it to the teacher."

Although the counselor was confused, he still moved his position.

After Qiao Xi inserted the USB flash drive into the USB port of the host, put her hand on the Counselor's mouse, found the data in the USB flash drive and called up a video.

Qiao Xi's slender index finger pointed on the computer screen with a cool voice, "teacher, this is the monitoring at the door of the toilet on the fifth floor of the library. Teacher, you can see here. Xiaoxiao put his backpack in the cabinet outside and went in.

After Xiaoxiao went in, CHEN Si, Deng Xiangyue and LV Fangfei also went in. They were still carrying bags. If they went to the bathroom, there was no reason to go in with bags.

About fifteen minutes later, the three of them came out one after another. Here, Deng Xiangyue took the black schoolbag from the cabinet. This is where Huang Xiaoxiao put his backpack before. In other words, they took Huang Xiaoxiao's backpack. "

Qiao Xi said, pointing to the lower right corner of the video, "then at 9:05, the library was closed, but Huang Xiaoxiao didn't come out. Teacher, I don't think I need to say what happened."

Tao Yun didn't expect Qiao Xi to make such preparations. Finally, they understood why Qiao Xi said to give it to her.

However, the three of them obviously spend most of their time together and are still in the same bedroom. Why don't they know when Xi Xi got this video.

The counselor frowned at the computer screen, "do you mean they locked Huang Xiaoxiao in the toilet? And took Huang Xiaoxiao's backpack?"

"Yes, Xiaoxiao has the habit of going to the library to study at night. At 9:30 that night, Xiaoxiao didn't go back to the dormitory. We were very worried and went out to look for it. I suspect that Xiaoxiao is in the library and looks separately from Tao Yun and Wei Qintong.

That's why the surveillance camera caught the two of them leaving, but didn't catch me leaving. I moved the camera because I knew that the security room was monitored in real time.

If I don't remove the surveillance, I'm found in the library. Before I find Xiaoxiao, I'll be taken away first, so I can only remove the camera. "

The counselor was lost in thought, "how do you know the password of the library? The informant said that they asked the teacher of library management that no one asked her for the password last night."

"I asked the headmaster."

"Headmaster?!" the counselor looked at Qiao Xi in shock, "how could the headmaster tell you..."

"Sorry, teacher, because it was too urgent. The headmaster and my brother were friends, so I asked the headmaster."

"So the headmaster knows about it?"

"Well, I told the headmaster, and the headmaster agreed to let me go in and look for it." Qiao Xi nodded.

The same is true, so she didn't lie.

The Counselor's eyebrows were still frowning, "that is to say, you asked the headmaster and the headmaster agreed. You can't blame you for this. However, are you sure it was CHEN Si who shut Huang Xiaoxiao in the toilet?"

"Teacher, I'm sure!" said Huang Xiaoxiao. Huang Xiaoxiao stepped forward and stood next to Qiao Xi. "Teacher, I was locked in the toilet last night. Although I didn't see them clearly, I heard their voices. Moreover, my schoolbag was also found by Yu Xue!"
