The darkness seemed to envelop the lake, and a white mist flowed slowly. Pen ~ fun ~ pavilion www.biquge.info

Teacher Chen walked on the edge of the lake, saying that he was strolling, but in fact, he was trying to dispel the tension and fear in his heart, and he actually did such a thing. The child died in the lake, and without mercy, he threw her into the lake with his hands raised.

There are many terrible things in this world, most of them are caused by human beings themselves, when we are children, we will hate those who do bad things, and when we grow up, we will find that we can actually do worse things for our desires.

He can be said to have never met with Mr. Cai in the past few days, and he has not entered the office again, so he doesn't know what Mr. Cai has been busy with these days, but the only thing that is certain is that she seems to be much calmer, and I don't know how she recovered from this huge grief blow.

He looked back at the school building, as if trying to see through the gray hidden inside the school building.

At this moment, Mr. Cai is teaching biology to students in the classroom of this gray school building, and today he is talking about how to avoid the spread of infectious diseases.

"Therefore, you must wash your hands when you go back after coming into contact with strangers in public, otherwise you are very likely to contract some kind of infectious disease." Teacher Cai's voice was very calm, just like all ordinary teachers, calmly imparting knowledge, and she couldn't see what kind of grief she had had.

"But can you ignore this problem even in a habitual environment?" Teacher Cai closed the book and looked up at the students below; "Think about it carefully, if a terrible disease can be transmitted through saliva, but the people around you happen to be suffering from this disease, in this case, shouldn't you keep a certain distance from the people around you?"

"For example, if you have lunch and someone happens to sneeze around you, you will infect yourself with some of the germs in their sneeze without knowing it. What if the person is seriously ill? What are the consequences of a serious illness that is difficult to treat, or even a serious illness that cannot be treated? ”

The students below were booed, and some female students even frowned sadly, and the scene described by Mr. Cai seemed to be a little disgusting, besides, how could it be so coincidental that the person who happened to sneeze would be seriously ill?

"Of course, this is only an extreme special case, and I am only here to draw your attention and increase your awareness of your own safety. In order to broaden your knowledge, I asked a few students to name common infectious diseases, and everyone should remember to take precautions. Li Runqi, you can answer. ”

Li Runqi frowned a little strangely, this is a bit abnormal, basically Teacher Cai will never shout to answer a question by herself, why would she let herself answer such a question at such a time.

He slowly stood up and stared at Teacher Cai, wondering what kind of medicine she was selling in her gourd.

"Oh, wait, before you answer, let me ask you a question, have you eaten at noon?" Teacher Cai smiled and said as if he had seen a joke.

"I've eaten it."

"Is it eaten at school? Has anyone been sneezing around you? ”

The students below burst into laughter for a moment, and Li Runqi frowned slightly, what is the point of this question? Does she really just want to know what she ate for lunch? Or is it just making fun of yourself?

"Eat at school, no one sneezes around me."

"Oh good, then it seems that you are lucky, next time you should pay attention to this precaution." Teacher Cai's face was smiling, and there was a kind of strategic confidence: "Then have you eaten our school's special steak?" ”

"Eat." Li Runqi was a little impatient, and he didn't answer the question in the end: "Can I start answering?" ”

"Oh, of course." Teacher Li continued to smile.

"Generally speaking, there are many diseases transmitted by saliva, the most common are upper respiratory cold, dysentery, foot-and-mouth disease, type A and type B。。。。。" His voice stopped abruptly, as if he had thought of something important.

In an instant, all the classmates turned their heads to look at Li Runqi, his face was pale, sweat flowed down his cheeks in an instant, his hands were clenched into fists with some unwillingness, his eyes were frightened, and he seemed to know something terrible.

Only Mr. Cai continued to smile, as if he knew why he paused: "Go on, is it good to say that you have to?" ”

"You..." Li Runqi's voice trembled slightly, and then he reported a terrible term: "Viral hepatitis E." ”

"Well, that's a good answer, sit down." Teacher Cai nodded in satisfaction, leaving a group of students who didn't understand it at all looking at the two of them suspiciously.

After sitting down, Li Runqi couldn't help but break out in a cold sweat, that's right! It's viral hepatitis E! This is the headmaster's disease, she actually injected the headmaster's saliva into her lunch! He felt a little scared, although she didn't say it directly, but the performance just now was already telling herself that you are not far from death.

"Don't you say?" Li Runqi was so frightened that he was about to curl up: "Am I going to die like this?" It can't be, why did it happen, how did she do it, she had to follow herself all the time to know exactly which plate of steak she was taking, and she had to inject saliva without the cafeteria aunt noticing, and at the same time she had to leave no evidence. This plan may seem feasible, but in practice it can be very difficult. It stands to reason that it is absolutely impossible. ”

"Could it be that there is something wrong with Mr. Chen again?" Li Runqi thought to himself, "It shouldn't be his problem, he has deceived him away from Mr. Cai through the bomb, if they don't meet in private, Mr. Chen will definitely not show any flaws, because they haven't seen each other for the past few days." ”

Thinking of this, Li Runqi was a little relieved, after all, it was a disease, and there was still the possibility of being treated, but that bomb was a real bomb, but he did deceive Mr. Chen, this is not a so-called balance bomb, but a remote-controlled bomb.

If you think about it, you'll know, who would put a bomb that won't explode next to someone who wants to kill if you don't touch it? This is completely counterintuitive, and if that person just didn't hit the bomb, wouldn't all his efforts be in vain? So Li Runqi thought about it early in the morning, to make a bomb that could be controlled remotely by herself, and it must be detonated at her most desperate moment.

Even if he was found and did not detonate, he could successfully shift the responsibility to Mr. Chen, why did he suddenly choose to change offices? Why did he never see Mr. Cai again? These can be evidence of the police's suspicions, so that they can buy themselves time, which of course is the worst outcome.

But now it's different, and we may not be able to wait for the so-called most desperate moments. Li Runqi thought to himself, maybe it should be detonated immediately to avoid another extraneous branch.
