As soon as Mr. Lu finished speaking, there was chaos below. Some female students even covered their ears and closed their eyes, as if they didn't want to listen.
Liu Yang was also taken aback. He moved the bench to lean against Lu Chu, wiped off his sweat, and whispered, "What's going on recently, why are you so uneasy..."
Lu Chu gave him a comforting look: "Don't panic, listen to what the teacher has to say."
Liu Yang nodded quickly.
"We suspect," Teacher Lu looked around, "the murderer is someone from the school."
When these words came out, the whole class was in an uproar again. Everyone looked at each other with horror in their eyes.
In fact, Teacher Lu didn't say anything. Compared with suspecting that the murderer was someone from the school, many people suspected that this incident was not artificial at all, otherwise it would be impossible to explain such a tragic death scene.
Immediately afterwards, Teacher Lu said: "This afternoon, I hope everyone can stay in the school and accept the police's interrogation and investigation."
"Teacher!" Meng Yu raised his hand.
Teacher Lu nodded: "You say."
Meng Yu stood up and said, "We still don't quite know what's going on. If, as you said, the murderer is someone from the school, isn't it unsafe for us to stay in the school this afternoon?"
Teacher Lu motioned her to sit down, and said to the class: "Don't worry about this for now, people from the police will come, and everyone should try to stay in the classroom as much as possible and avoid acting alone. At that time, there will be several teachers in each class for the whole process. follow."
Regardless of how panicked the class was, Teacher Lu gave some instructions and then left in a hurry.
Lu Chu turned his head and exchanged glances with Qi behind him, both of them knew each other clearly.
When the bell rang for the end of get out of class, no one dared to leave their seats. The girls hugged each other in a group and squeezed into the middle of the seats to find a sense of security for themselves.
Zhang Zhang sent a note to Lu Chu, asking him what the situation is now, and Lu Chu sent it back, conveying his idea of going out and asking who knows what happened.
Zhang Cheng is not a coward, and soon hit it off with Lu Chu, the two left their seats, Qi also stood up, and the three of them walked out of the classroom. As a friend of several people, Qian Wenhao immediately got up and followed out of the classroom, The rest of the class looked at each other.
There were not many people in the corridor. It seemed that everyone had heard the news, and they huddled together in class and refused to come out.
Lu Chu and the others went down two floors, and arrived at the place where the senior one had classes. Unlike the quiet upstairs, it was very noisy here, but it was not lively, but more panic and chaotic.
Lu Chu saw a few schoolboys who were discussing something together with bad looks, so he went up to ask.
These people are classmates in Class 1 and 5 of Senior High School.
———
There are several laboratories on the fifth floor, mainly chemistry and biology laboratories. The teacher who had the accident was in charge of the biology laboratory, but the strange things that happened later were not limited to the biology laboratory, so the fifth floor of the laboratory building was sealed off stand up.
After the top floor of the laboratory building was sealed off, the experimental instruments inside were not moved, but a batch of new experimental instruments were purchased in a new laboratory.
The top floor is sealed off, and generally no one will go up. Students who don't know the truth can't go up because of the strong iron lock even if they are curious. Other lab teachers who have keys remember that a colleague died there, and they won't go up. I also avoid it when cleaning on weekdays. After a long time, from the stairs on the fourth floor up to the various laboratories, a thick layer of dust has accumulated. Groups of students holding textbooks were chatting lively. When they walked up the stairs to the fourth floor and were about to turn into the corridor, a student suddenly pointed to the stairwell from the fourth floor to the fifth floor and said, "Hey , That is, footprints, right?"
"What?" The student's words instantly aroused the curiosity of the others, and everyone gathered together and looked in the direction he was pointing.
The stairwell had accumulated a lot of dust, and there was a particularly obvious footprint on the second step of the stairs.
A few students looked up the steps, and saw that there was a footprint on every other step, and they were all left feet.
A few students were curious at first, but when they reacted, they felt chills all over their bodies, because the stairs starting from the fourth floor were all behind iron bars, and the iron bars pushed up to the roof and were relatively dense. Climbing is impossible for people.
And those footprints are bare feet.
Several students were taken aback. Someone screamed and ran downstairs, just in time to bump into the chemistry teacher who had just come over.
The chemistry teacher reprimanded: "What's the matter, how many times have I told you not to chase and fight in the corridors of the teaching building, why don't you listen, what should I do if something goes wrong?"
The student stammered and pointed upstairs: "Teacher, where is... yes..."
After a long time, I couldn't tell what it was, the chemistry teacher was puzzled, and simply said: "If there is anything, come with me, the class is about to start, this time the experiment is more troublesome, if you delay the time, you will not be able to finish the class. "
The student obediently followed behind the chemistry teacher and walked upstairs. At this time, there were more people around the stairs on the fourth floor. The students who had already entered the laboratory all came out to join in the fun after hearing the noisy movement outside.
Because of the large number of people, the tense atmosphere was reduced, and those who were originally scared began to speculate about what happened to the footprints.
A student joked: "Could it be possible that the thief took off his shoes and jumped up two steps on his own?"
The others laughed together.
The chemistry teacher came over and saw so many people gathered here, and said angrily: "It's almost time for class, can't you stay in the laboratory to familiarize yourself with the experimental procedures and experimental equipment? You can do the experiments? You can write the reports?"
When everyone saw the teacher coming, they immediately corrected their posture.
Someone said: "Teacher! The laboratory building has recruited thieves!"
"Thief?" The chemistry teacher frowned, "Where did the thief come from? What is there to steal in the laboratory building?"
The student said: "Teacher, our experimental instruments are quite valuable. What if the thief is interested in this, look, there are still footprints in the stairwell from the fourth floor to the fifth floor!"
The chemistry teacher looked over and saw the string of lonely footprints. She couldn't say it was weird in her heart, but when she thought that if it was really a thief, the school would suffer heavy losses. She saw it but didn't deal with it.
So she asked the students to step aside and told the laboratory teacher who was on duty today. Hearing this, the laboratory teacher came over with the key to the fifth floor. The students dispersed automatically, and the teacher opened the huge chain lock. The iron lock, pushed open the iron bar door.
The chemistry teacher asked the students to go back to the laboratory to wait, while he and the laboratory teacher went upstairs to have a look.
A tall male student said: "Teacher, let me go with you. If it's really a thief and the thief hasn't left yet, bring a few taller boys with you to be safe."
Thinking of this, the chemistry teacher nodded: "Alright, thank you, let's ask some boys to join me."
Several boys took the initiative to follow the chemistry teacher upstairs. Although the others were curious, they followed the arrangement and returned to the laboratory to wait.
The chemistry teacher and the laboratory teacher walked in front, and several boys followed, and they all avoided the barefoot footprint in unison.
Turning into the laboratory corridor along the stairs, they found that the single foot footprint had turned into a laboratory.
The laboratory teacher wiped the sudden sweat from his head: "This laboratory is the laboratory where the teacher had an accident..."
The chemistry teacher paused and said, "Go in and have a look."
"No," the lab teacher shook his head, "I need a key."
She continued: "I'll go down and get the key, you guys wait here." After finishing speaking, she went downstairs.
The corridor was extremely quiet, and needles could be heard, the white floor was covered with taupe dust, and the string of footprints stretching towards the laboratory was particularly clear and eerie.
A male classmate swallowed his saliva: "I don't think it looks like a thief."
The person next to him slapped him: "It's broad daylight, don't talk nonsense."
Soon, the lab teacher came back with a bunch of keys in his hand.
Because it has not been used for a long time, there are some rusts on the key, and it is very difficult to insert it into the keyhole. The others did not speak again. In order to ease the atmosphere, the laboratory teacher opened the door and said: "If I knew it, I would bring some more oil. This key is too difficult... "
The door opens.
Her words came to an abrupt end.
The chemistry teacher covered his mouth and took a deep breath.
"Teacher, what's the matter?" The students behind were puzzled, because they were taller, they looked past the two teachers and looked forward.
The air stagnates.
The boy lost all color on his face and took two steps back.
The laboratory was in a mess, the dust on the ground merged with the solidified black and red blood, and the footprints of one foot changed from clear to bloody, all over the entire laboratory.
In the middle of the laboratory, a boy was sitting there. A rope was tied around his neck, and the other end of the rope was tied to the chandelier above his head, barely stabilizing his body. His two upper and lower eyelids were propped open by a short bamboo stick, and the two ends of the bamboo stick were inserted into the flesh, oozing a little bit of blood.
A microscope was placed on the experimental table, and the dead man was propped up by bamboo sticks to look straight at the microscope in front of him with his ashen and lifeless eyes, as if he was doing an experiment seriously. On the stage of the microscope, a square piece of meat sliced as thin as a cicada's wing was placed on it.
Such meat slices are evenly stacked in a row in the container next to the microscope. They are cut to a similar thickness and look very fresh. On the right side of the container, there is a divided right leg. A piece of meat on the thigh was missing, and the piece of meat was cut off and placed on the other side. A knife was inserted on it, keeping the cut The shape of the sliced meat was exactly the same as that seen under the microscope.
The deceased sitting on the chair happened to be missing a right leg.
