As soon as Mr. Lu's words fell, the following became confused, and some female classmates even covered their ears and closed their eyes, a gesture that they didn't want to listen.

Liu Yang was also startled. He moved the bench and leaned against Lu Chu, wiped his sweat, and whispered: "What's going on recently, why is it so uneven ..."

Lu Chu gave him a soothing glance: "Don't panic, listen to what the teacher said."

Liu Yang nodded quickly.

"We doubt it," Teacher Lu looked around. "The killer is a person from the school."

When this word came out, the whole class was in an uproar again. Everyone looked at each other with panic in their eyes.

In fact, Mr. Lu didn't say anything at all. Compared with the suspicion that the killer was a person in the school, many people were more suspicious that the incident was not artificial, or it could not explain such a tragic death scene.

Immediately afterwards, Mr. Lu said, "This afternoon, I hope everyone can stay in the school and be questioned and investigated by the police."

"Teacher!" Meng Yu raised her hand.

Mr. Lu nodded: "You said."

Meng Yu stood up and said, "We are still not quite sure what is going on. If, as you said, the murderer is a person from the school, then we stay in the school in the afternoon, isn't it safe?"

Teacher Lu instructed her to sit down and said to the whole class: "For the time being, you can rest assured that there will be police people coming over. Everyone should stay in the classroom as much as possible to avoid acting alone. By then, there will be several teachers in each class. Follow. "

Regardless of the panic in the class, Mr. Lu ordered a few words after he spoke, and then left in a hurry.

Lu Chu looked back and looked at the 7 pairs behind him, and they were all clear in each other's eyes.

The bell rang at the end of the class, and no one dared to leave the seat. The girls were huddled together and huddled together, pushing hard to the middle of the seat to find a sense of security for themselves.

The charter passed a note to Lu Chu asking him what the situation was. Lu Chu passed it back and prepared himself to ask who knew what was going on.

The regulations were not small, and they quickly agreed with Lu Chu. The two left their seats and 7 also stood up. The three walked out of the classroom. As friends of several people, Qian Wenhao immediately got up and walked out of the classroom. The others in the class looked at each other.

There were not many people in the corridor. It seemed that everyone had learned the news, and they did not want to come out in the class.

Several people from Lu Chu walked down two floors, and they arrived at the place where the class was in high school. Unlike the quiet upstairs, this place is very noisy, but not busy, but more panic and chaotic.

Lu Chu saw a few schoolmates who were not together and were discussing what they were discussing, so they went up to ask.

These people are classmates in class one and five.

There are several laboratories on the fifth floor, mainly chemistry and biology laboratories. The teacher who was in the accident was in charge of the biological laboratory, but the strange things that happened later were not limited to the biological laboratory. Therefore, the fifth floor of the experimental building was sealed. stand up.

After the top floor of the experimental building was closed, the experimental instruments inside did not move, but a new batch of experimental instruments was purchased in a new laboratory.

The top floor is blocked, and generally no one will go up again. Even if the students who do n’t know the truth are curious, they ca n’t go up because of the strong iron locks, and other lab teachers with keys remember that there were colleagues who died there, and they would not go up. They also avoid it during cleaning on weekdays. Over time, a thick layer of dust has accumulated from the stairs on the fourth floor up to the various laboratories.
