Guan Zheng came back to his senses and said, "It's nothing. Pen, fun, pavilion www. biquge。 info go check it out. ”

Xu Jiuyan nodded and said to Jia Zhenkai: "Then let's go first, thank you steamed buns!" ”

Xu Jiuyan took the document in Guan Zheng's hand and said, "I came to see this, no wonder I was so stupid." ”

Guan Zheng looked up at the sky and said, "I really don't want this. ”

"Does this have anything to do with you?"

"My biology teacher, Feng Yuan, was just invited to join the Department of Bioengineering at Nanyi University as a professor last month, and she is the head of this lab."

Even Xu Jiuyan was stunned, such a coincidence?

Guan Zheng nodded and said, "What should I do if it's really her?" ”

"I'm waiting for your answer."

Xu Jiuyan looked at Guan Zheng's empty expression and said, "Don't forget what you said, the peaceful and prosperous world is because we are moving forward with a heavy load. ”

Guan Zheng was silent. For Guan Zheng, he has never been so worried.

Guan Zheng slowly started the car and went straight to Nanyi University. Guan Zheng parked the car on the asphalt side of the campus and got out of the car with Xu Jiuyan.

The trunks of the trees that had shed their leaves stood on either side, and the school building towered behind the trees, but it could not hide the light and appearance.

Guan Zheng pointed to the spiral building in the distance and said, "That's the Department of Bioengineering." Its shape is the double helix structure of the DNA molecule, implying that the biological era is never-ending. ”

"Boy! Don't stand in the way! As soon as Guan Zheng heard the voice that was both rigid and soft, he knew that it was Feng Yuan.

I don't know why, Feng Yuan's voice can always give Guan Zheng a sense of steadiness.

Guan Zheng turned his head and saw Feng Kite's still smiling face, Feng Kite was still holding a few books in his hand, looking like he had just finished class.

Guan Zheng smiled and said, "Teacher Feng, long time no see." ”

Feng Yuan nodded and said, "Officer Guan, long time no see." ”

Guan Zheng smiled a little embarrassedly: "The teacher is joking with me." ”

Feng Yuan looked at Xu Jiuyan and said, "It's a 10th grade graduate of the third middle school, Xu Jiuyan from the eighth class?" Xu Jiuyan smiled and said, "Do you remember me?"

"How can I forget, others can't say it's good, as long as it's my class representative, I won't forget it!"

Guan Zheng patted Xu Jiuyan on the shoulder and sighed: "The world is so small! Little sister! ”

Xu Jiuyan pushed him away with a look of disgust and said, "Who is your little junior sister, shameless." ”

Feng Yuan smiled and said: "When he was in school, he was like this, relying on his good grades in biology and chemistry, but he arrogantly let the whole school remember that there was such a character in class 11." ”

Xu Jiuyan said approvingly: "Oh, this can't be changed now." ”

Feng Yuan saw the handcuffs around Xu Jiuyan's waist and said, "You applied for the law department of Nanjing University for the college entrance examination, right, and you also became a policeman?" ”

Xu Jiuyan nodded and said, "Yes, I like it." ”

Feng Yuan still smiled and said, "It's good if you like it, no matter what line of work you are in, as long as what you do is people-oriented, the teacher will be happy." ”

Feng Yuan brought Guan Zheng and Xu Jiuyan into the office and said, "The two police officers came to me, it should be because of the loss of drugs in our laboratory, right?" ”

Guan Zheng said: "Teacher, our duty is here, so it's rude." ”

Feng Yuan smiled and said, "How can it be considered rude to be conscientious?" Yes, the bioengineering laboratory of Nanyi University is a provincial key laboratory and a national key training laboratory, which has the most advanced testing instruments and experimental instruments in the field of bioengineering in China, as well as many controlled chemicals necessary for experiments. When I counted the medicines last week, I found that some benzene was missing, and there were also Class 1 explosives. ”

Guan Zheng asked: "What kind of first-class explosive is it?" ”

"It's calcium carbide. As you know, the main components of calcium carbide are carbonization and calcium, which can be used to make ethylene and alkyne in the laboratory, and ethylene and alkyne can be used as growth hormones or related reagents, so they are widely used. However, calcium carbide is flammable when wet and is a controlled drug, so I reported it. ”

Guan Zheng nodded and said, "Who can come into contact with these things at any time on weekdays?" ”

"Me!" Feng Yuan said without hesitation.

Guan Zheng was stunned for a moment and said, "Can you elaborate on it?" ”

Feng Yuan said: "Because I am in charge of our laboratory, everyone comes here to teach or experiment, and my assistant and I have to do the relevant work, and in addition to the academic affairs office, only I have the key." ”

Guan Zheng didn't know how to ask, so he said, "Can I meet your assistant?" ”

Feng Yuan nodded and said, "Of course you can." He should be in the classroom, I'll call him. ”

Guan Zheng's thinking slowed down suddenly, and he didn't know who to suspect.

Feng Yuan smiled and said, "You two don't need to be so sad, right?" ”

Guan Zheng hesitated for a moment and asked, "By the way, have you been to Tang Dynasty KTV recently?" ”

Feng Yuan shook his head and said, "You all know that I have a bad heart, and a place like KTV is unattainable!" But Wang Weiqi and they went to it a few days ago, it seems to be called Tang Dynasty KTV. ”

As he spoke, a young man with glasses walked in.

Feng Yuan stood up and said, "Come, classmate Wang Weiqi, these two are my students, and they can be regarded as your senior brothers and sisters." ”

Wang Weiqi held her glasses, stretched out her hand with a smile, and said, "Senior brother and sister are good." ”

Guan Zheng and Xu Jiuyan nodded, and Guan Zheng said, "Please sit down, we are just here to ask you a few questions." ”

Wang Weiqi looked at Feng Yuan, then sat down opposite Guan Zheng and said, "What do you want to know?" ”

"We want to ask what you think about the loss of benzene solution in your lab?"

"Well, it's normal, every laboratory will have a certain amount of solution that doesn't know where to go, just like there will always be losses in experiments."

Guan Zheng said: "But I think you should know that benzene solution is flammable and explosive, and there is a certain danger. ”

Wang Weiqi shook his head and said, "Then I don't know, why are you asking this?" Suspect me of arson? ”

Guan Zheng looked at Xu Jiuyan, and Xu Jiuyan said: "We have been talking about an arson case recently, and we will ask about it according to the routine. ”

Wang Weiqi then asked: "Is it the one from the Tang Dynasty KTV?" ”

Guan Zheng asked: "Are you also interested in this?" ”

"No, after all, it's a pretty famous one, and it's said to be very explosive!" Wang Weiqi's tail note rose slightly, making Xu Jiuyan tremble.

Guan Zheng then asked, "Have you been to Tang Dynasty KTV recently?" ”

Wang Weiqi nodded and said, "Yes!" A few of our college classmates went to a party the other day. But at that time, the Tang Dynasty KTV was still good, but there was no fire. ”

Guan Zheng asked: "Where were you from five to six o'clock last Friday night?" Who can testify? ”

"Last Friday? I'm in the lab, and Professor Feng can testify. ”

Feng Yuan thought for a moment and said, "Yes, our laboratory is counted every week, and the two of us cleaned up the medicines in the laboratory last Friday. ”
