Chapter 554

"How do you know he's dead?" Yang Yu asked in surprise.

Xiao Qing then took out a stack of information from her bag and said, "he is on the list of the dead."

"And you guessed right again." Xiao Qing took out one of the diagrams and spread it on her desk. She said, "we came in according to the time of death, sorted it out and drew it into a graph. Then we investigated the relationship between men and women in the upper and lower levels, and found that all of them had sex."

Looking at the diagram, the old headmaster was surprised and said, "are so many people dead? This has something to do with the case of our school's experimental building? "

"It's a case in case." Yang Yu replied, looking at the information on the diagram, he did find one of the dead. He was in the bottom of the line and died not long ago.

"So there are two points that can be officially confirmed now: first, it is an infectious disease, viral; second, the route of transmission is sexual behavior. It's just that we don't know what kind of virus it is. We have submitted it to a more advanced R & D Organization for testing. " Xiao Qing admires Yang Yu very much. He is very inspired by the case. This kind of sensitivity is definitely not what a junior high school student should have. Generally, experienced veterans have such experience in solving cases.

Therefore, Xiao Qing had a great curiosity about Yang Yu.

Yang Yu looked at the diagram, in chronological order out of the appearance, he already in the heart: "sure."

"What did you find?" Xiao Qing asked.

"One spread two, two spread four, four spread eight, viral spread. If it goes on like this, the whole city, even the whole country and the whole world will fall into the crazy spread of this virus." Yang Yu saw an unprecedented sense of crisis.

"With the spread of sexually transmitted diseases, there are so many measures to prevent the spread of sexually transmitted diseases." Xiao Qing retorts that the truth she put forward can really refute Yang Yu's worries. Isn't Aizi and Meidu the same and not so terrible?

Yang Yu ponders that his biggest question now is the purpose.

"Aren't there four other boys? We'll find them out and ask what happened that night. " Yang Yu's heart has raised a very ominous premonition: "yeqinqin was missing that night, I suspect she has died, or even murder."

"Ah?" Yang Yu's judgment made the old headmaster extremely surprised: "you said that those boys killed Ye Qinqin in the toilet on the second floor of the experimental building that night? Then, ye Qinqin becomes a fierce ghost and stays in the world for revenge? "

"Yes Yang Yu still admires the inference of the old headmaster.

"Is there really a fierce ghost?" Xiao Qing is always reluctant to believe this.

Because it's Sunday, the students are out of school, but many students live in high school.

Yang Yu and Xiao Qing find several junior high school students who are the leading boys, ask about the situation, and get an important clue.

The boy who takes the lead is the second generation of Mingfu. He is arrogant and domineering. He is not short of money at ordinary times. He has four younger brothers who eat and drink with him. But he has a big problem, which is lust. Therefore, his group of five often bullies and plays with girls, and there are countless girls who are bullied by them.

"This is the information of the remaining four people. I made a comparison with the dead. There are five people in total. Four people have died. They are all on the death list. Only the last one Duan Xin is still alive." Xiao Qing's face is very ugly.

"Go to find the only survivor right now. He should be the only one who knows the truth. It's very important for this case. Now, we've finally connected everything." Yang Yu knows that the case has reached the most critical place: "what I am most afraid of now is."

"I'm afraid he's dead, too?" Xiao Qing asked.

Yang Yu shook his head and said: "if we calculate according to the logic of the fierce ghost's revenge, then what kind of revenge does the fierce ghost rely on? Because she can't leave the experimental building, as long as those people don't go to the experimental building, the fierce ghost can't complete revenge, so what does she rely on for revenge? "

"The spread of the virus?" Xiao Qing cried out.

"That's right."

"That means if the fifth suspect doesn't die, the spread won't stop?" Xiao Qing feels that her brain is also open.

"Yes, logically." Yang Yu replied.

They got into the police car and went to the fifth suspect.

According to the home address provided by the school, they went directly to the man's home.

But the parents said that the children live in school and have not been home this semester.

Yang Yu and Xiao Qing went to school again and found his roommate. The answer is that they haven't been back to their dormitory for a long time!

"Missing, too?" Xiao Qing felt that everything was so confused: "will we die somewhere, and we don't know? It may have been a virus attack! In what corner did you die? "

"No, he's alive. He should be hiding." Yang Yu replied.

"I see. I'll go back to the city and find him. " Xiao Qing's voice is respectful to Yang Yu, and she doesn't treat him as a child.Yang Yu and Xiao Qing separate and go back separately.

Yang Yu calculated the time. Time is running out. He is afraid that Su Qi will not be able to make it to that time.

Wait a minute, Yang Yu suddenly feels wrong. Su Qi, a student sister, has only had a relationship with herself. Now it must be sexually transmitted, so she has been infected, right? But who passed it on to you? Li Bi? The order is not right. There is only one woman, ye Qinqin, but ye Qinqin is dead?

Yang Yu's brain is big, have you ever been infected? How much time do you have for yourself? I must have died earlier than my sister, but I don't have any blisters or other disgusting things on my body!

Yang Yu is suffering back to the rental room, the shop decoration also to forget.

Yang Xueyu knocked at the door of the school, but there was no response.

At this time, the door of the opposite room opened.

Come out a beautiful woman.

This woman Yang Yu knows that the opposite couple are office workers, but they are also fresh graduates. Yang Yu has heard her cry several times, and her voice is sweet. Unexpectedly, when she first saw her, she was so sweet?

Yang Yu had a good look at this beauty with long hair. She had beautiful hair. She was twenty-three or forty years old, almost the same as Li Ruoshui. She was really beautiful.

But the woman didn't look at Yang Yu and passed by. When

passed by, Yang Yuwen came to a faint smell of perfume and good smell.

"This is the woman." Yang Yu sighed that Chen Jiaying and Tan Fangfang, who played last night, could not cover up their immature faces no matter how precocious they were. This woman is the real woman.

But he was not looked at. Yang Yu overestimated his charm. It seems that his popularity with girls in school gave him a big illusion. When, if can be like last night to sleep to rape Tan Fangfang, that can be enjoyable.
