Du Fan and his girlfriend Zhang Siqi held hands and came to the gate of the Beiwan District Police Station, looking at the two big words "Public Security" not far away, Du Fan just glanced at it coldly. For him, the police www.biquge.info have an indelible memory.

After the two registered in the guard room of the police station, they walked in together. As soon as they walked into the hall of the police station, an enthusiastic policeman stepped forward to them and asked, "You two, do you need any help?" ”

Looking at the very enthusiastic policeman in front of him, Du Fan smiled slightly and said: "Hehe, comrade policeman, we are the informants in Zhang Guohua's case, and the comrade police in charge of that case wants to learn about the situation from us, so we came over." ”

"Oh? I see. But I think you'd better wait here for a while. ”

"Why?"

"That's right, Team Chen, who is in charge of Zhang Guohua's case, is not in the office now, and he has already gone out of the scene to perform official duties after receiving the report."

"Isn't Zhang Guohua's case being investigated? How can there be other cases? ”

"Eh, ahem, this young man, this is a secret for our police, it's better not to ask. However, Zhang Guohua's case has been confirmed as a suicide, so I guess I just asked you to deal with the follow-up matters. ”

After listening to the words of the enthusiastic policeman in front of him, Du Fan suddenly became enlightened:

It seems that although Zhang Guohua's case has been seen through by someone, he has not yet had time to apply for a new investigation, so the police here should not know. And the scene where the so-called Chen team is going to now should be the city hospital, which means that Dean Zhao's body has been found. But the body was found much later than I expected.

"Well, okay, thank you, then we'll come back later." After Du Fan said goodbye to the enthusiastic policeman, he left the police station with his girlfriend Zhang Siqi.

On the way back, Zhang Siqi said to Du Fan: "Fanfan, why did Dean Zhao's body not be found until now, according to your plan at that time, the body should be found soon, and then call the police, but now it's a night away." ”

"I don't know about this, before the verdict against Dean Zhao, I investigated, at that time every night, his mistress will have a tryst with him in the form of a report, it stands to reason that when his mistress finds his body, she should scream, although the door of the dean's room is very soundproof, but his mistress will definitely call the police after screaming, this is a person's knee-jerk reaction. But why was the body not found until this morning? I guess I need to look into this. ”

"Well, then you have to be careful. By the way, Fan Fan, you said that you investigated that Dean Zhao had a mistress, did you pretend to be a doctor in the hospital and secretly observe? Zhang Siqi said after thinking about it.

"Hehe, Kiki, who knows me." Du Fan teasingly scratched Zhang Siqi's nose.

"Fanfan, will you promise me?" Zhang Siqi snuggled up to Du Fan's chest and said suddenly.

"Huh? What the? What promised you? Du Fan looked down at his lover without knowing his head.

"I'll ask you if you say yes." Zhang Siqi looked at Du Fan and said with a puffed mouth.

"Well, okay, no matter what you say, I promise you."

"Well, you have to remember what you said today. Let's go, let's go to the city hospital to see the situation first, and then go to the police station later. After Zhang Siqi finished speaking, he left Du Fan's firm and warm chest and walked forward first.

Looking at Zhang Siqi's back, Du Fan was stunned in place, what the hell is this, he doesn't understand it at all. Even if he has a very high IQ, he is a mallet when faced with emotional problems and Zhang Siqi's own thoughts.

Zhang Hao's dormitory 505 of the Municipal Public Security Bureau.

Zhang Hao sat on his bed and looked at Liu Feng, who had found a stool opposite him and sat down, his eyes showed eager anticipation: "Ah Feng, you said that the report I asked Ah Rong to test the air has come out?" ”

"Well, the report is here." Liu Feng handed a file bag that he had been carrying with him to Zhang Hao, who was sitting opposite him.

Zhang Hao took the file bag from Liu Feng's hand, then opened it and took out a stack of reports from it. Putting the empty file bag on his bed, Zhang Hao carefully looked at the stack of air test reports.

According to the air test report, the percentage of carbon dioxide in the blue Santana taxi that was hit reached 0.046%, and the normal percentage of carbon dioxide in the atmosphere should be 0.03%, which means that the amount of carbon dioxide in the taxi is 0.016% more than the amount of carbon dioxide in the outside atmosphere.

Zhang Hao still clearly remembers that when he was in the taxi, he felt the humidity, especially on the clutch and accelerator. At that time, I did not feel the temperature in the car, which means that the taxi was damaged, and most of the carbon dioxide in the car was expelled and mixed with the atmosphere.

The amount of carbon dioxide in the atmosphere or in a taxi exceeds 0.05%, which will exacerbate the greenhouse effect.

After carefully reading the air detection report, Zhang Hao suddenly laughed excitedly: "Hahaha, Ah Feng, my speculation turned out to be right, and now I finally know how the murderer accelerated the driverless taxi instantly." ”

"Oh! You got it? So what's going on? Liu Feng desperately wanted to know the answer.

"Hehe, after I wash my face and brush my teeth, we will 'visit' the scrap metal of the car that has been hit and does not look like a car. I'll explain it to you live. Also, when I'm done, let's solve the mystery of how the murderer disappeared from the taxi. ”

"Huh? Ah Hao, even you have solved this? ”

"Hehe, this is not the case, but I think it will be soon, when all the mysteries are solved, I will end my vacation early and take over your current case." Zhang Hao finally came to the point of complete interest at this time, because after solving the mystery of the murderer making the driverless taxi suddenly accelerate, he had a bold guess, but this guess still needs to be verified by himself, and the best way is to end the vacation early and devote himself to the case.

"Well, if you need help at that time, you can find me as soon as possible, who made us good brothers. Hehe. Liu Feng sat down next to Zhang Hao and patted the latter's shoulder, "And you poke out of the horse, no murderer wants to escape the punishment of the law." ”

Zhang Hao did not respond to Liu Feng's exaggerated statement, but smiled slightly, not thinking so in his heart. The murderer this time is definitely not that simple, if my bold guess is confirmed by then.................................
