At this moment, two male teachers arrived and began to disperse the students, preventing them from any further access to the bin.

Subsequently, the police car also came to the campus.

The students gathered to the sidelines and exchanged ears, watching as the police used yellow tape to circle a cordoned off around the garbage bin, so that no unrelated people were allowed to enter.

"Oh my God, this can't be a big case of abandoning corpses, our school is famous!"

"Don't you look at the excitement there, don't you think it's a big deal, shouldn't you be afraid if this kind of thing happens?"

At this moment, a tall female teacher with gray hair but a straight waist appeared behind them.

It's the head teacher, Masako-sensei.

Her rough voice coughed and shouted, "Students, go back to class, don't stay here." ”

The students, who had been watching the excitement, were so frightened that they dispersed when they heard what seemed to be a mouse hearing the cry of an old cat.

After returning to class, Yingying did not tell Sayuri about the disgusting sights she saw.

She knew that if she did, she would not be able to sleep at night.

Even Yingying herself, recalling the picture at that time, still had stomach cramps, and she was extremely frightened when she thought about it.

She felt that the person who did it was either perverted or crazy.

The rest of the class in the afternoon was almost impossible to attend, and the students in the class were either overexcited or frightened, and no one could calm down and listen to the class.

The teachers who gave lectures frequently knocked on the blackboard for roll call, but it was useless to see it, so they simply didn't care.

Moreover, their own hearts were beating drums and panicking.

At the end of class, the students gathered together to discuss this matter, and the atmosphere was warm.

Although Yingying did not participate in the discussion, she has been paying attention to the dynamics of this matter.

After a while, someone returned to the class and told everyone that the biology teacher had been called to the principal's office by the police to talk.

Hearing this new information, everyone exploded.

The biology teacher is a young female teacher with long hair and a penchant for wearing skirts, which is usually very popular with the male students at school.

No one could have imagined that this matter could have anything to do with this delicate female teacher.

After another lesson, someone saw three police cars parked on the edge of the playground drive away.

"The biology teacher won't be, find out that your boyfriend has done something sorry for you, and kill him in a rage. A female classmate who usually likes to make soap operas the most makes a guess.

A male classmate next to him pouted, "Eh, you can't talk nonsense." How could a biology teacher do such a thing!

Besides, if this was the case, the police car would have taken her away a long time ago. You see, she's still here. ”

Just when everyone was frowning and didn't understand why, there was new information.

When a student passed by the door of the principal's office, he overheard the conversation between the biology teacher and the principal.

I heard the principal say, "Those bones are all pigeon and mouse bones, aren't the small animals in our laboratory missing?"

Then the biology teacher replied, "I did lose a few." The key to the school's laboratory has always been my sole care.

I'm pretty sure I lock the door every day before I leave. ”

Now the students had a heated discussion, it seems that those bones are not human bones, but the bones of small animals raised in the biological laboratory and used for experiments!

This time, the case has been reversed again, and it seems that it is not a case of murder and abandonment of corpses, but a case of mutilation of small animals.

Ying Ying listened to it and felt very strange.

How could anyone do such a thing to a small animal used in an experiment!

When she returned home that day, she called and told Xiaohai about this strange case on campus.

Xiaohai was very interested and felt that this matter was very bizarre.

"It stands to reason that animals like beasts of prey and birds of prey like to eat these little mice, rabbits and so on.

But, strangely, the bones were found in the trash.

Could it be that the beast finished eating and politely packed up the remaining bones and threw them in the trash?"

Xiao Hai reasoned, but in the end, he couldn't figure it out.

Ying Ying sighed, "Whether it's a man or a beast, this matter is too cruel. And, how did it get into the lab?"

Both of them were silent, neither of them could answer, and after a little more talking, they went about their own business.

Ying Ying promised Xiao Hai that she would definitely tell him if there was progress.

****

On the second day, as soon as Ying Ying entered the campus, she saw two police cars parked at the front and back of the main entrance of the building.

The area is still surrounded by yellow tape and no-go near the dumpsters, and a young police officer stands next to it.

Ying Ying walked into the classroom and caught a glimpse of several classmates gathering together and chatting about something.

She listened intently and heard what appeared to be the school's biology lab that had been sealed off by the police for investigation.

It seems that it really has something to do with the biology teacher, a classmate whispered.

Ying Ying noticed that the students' reactions to this case were a little different from yesterday, and they no longer had the excitement when the case first happened yesterday.

Today, it is replaced by a secret curiosity and fear.

The morning passed quietly, and there were no more classmates running around in the corridors, let alone people delivering news.

Teacher Masako, the head of teaching, stood in the middle of the two corridors, her tall body full of intimidation, and everything was back in order.

However, this does not mean that the students are not interested in this matter, and they will still discuss it in private.

Before lunch, the police cars drove away, and the biological lab was back in use, but the garbage bins were still surrounded by yellow tape.

Seems there is nothing wrong with the biological lab?

At lunchtime, Ying Ying and Xiao Hai met at a Tianpu shop in the commercial street, and while eating, they told him about the development of the morning.

Xiao Hai listened to her story silently, lowered his head and pondered for a while, and said to Ying Ying, "I probably understand what happened now, but I need to confirm one thing." ”

Then, Xiaohai urged Yingying to finish the meal, and the two came to Yuchuan High School together.

At Xiaohai's request, Ying Ying took him to the biology laboratory, which was at the end of a corridor on the third floor, a room away from Mr. Kobayashi's office.

The biology lab is usually locked when there is no teacher in it.

Xiao Hai stood outside the door, carefully looked around the door frame and the doorknob, then nodded, and pulled Ying Ying out of the building.

They went around to the side where the window of the biology lab was facing, and Xiao Hai looked downstairs to the lab on the third floor and nodded.

He dragged Ying Ying to a secluded place where no one was around, and then said, "It's the same as I thought, and there is no trace of intrusion." ”

Ying Ying said, "Well, but what does that mean?"

Xiaohai continued, "This just verifies my reasoning yesterday." ”
