Guan Zheng remembered that Xu Jiuyan lost her father that year, so she turned around and said: "Feng Yuan is a teacher I respect the most." Pen & Fun & Pavilion www.biquge.info I was really good in high school, and I always worked against the teacher, but I only listened to Feng Yuan's words.

Her classes are not just books, they are life. She always talked to me about her affairs, patiently guided me and hinted at what I should do. If it weren't for her, I might have dropped out of school and become a gangster. ”

Guan Zheng said, shaking his head a little helplessly, and then said: "Before the college entrance examination, she guided me what kind of school to apply for and what kind of major to study. I have always been in contact with her, and she supported me before joining the police, telling me that it was time to do something for society.

Really, I can't forget her in my life, it was the History Bureau that made me embark on the road of the police, but it was Mr. Feng who gave me the capital to embark on this road. ”

Xu Jiuyan smiled slightly and said, "At that time, I was hesitant when I was divided into arts and sciences, and she helped me finalize my academic theory, otherwise I wouldn't have been admitted to Nanyi University." ”

Guan Zheng unceremoniously put his arm on Xu Jiuyan's shoulder and said, "Little junior sister! We are really fateful! ”

"Take your claws away!"

Guan Zheng played Lai Pi and said, "Bite me!" Bite me! Bite me! ”

"Childish!" Xu Jiuyan said with a smile: "Seriously, if you don't make a decision, this case will be handed over to someone else!" ”

"I've decided!" Guan Zheng stood up, as if relieved.

After a long time, Yan Ma got up and said, "What decision?" ”

"According to the normal procedure, summon Feng Kite!"

Early in the morning, Feng Yuan came to the police station, and as soon as he entered the door, he saw Guan Zheng and Xu Jiuyan already sitting at the table waiting.

Guan Zheng rarely arrived at the interrogation room before the suspect, then stood up and greeted with a smile: "Teacher Feng, please take a seat." ”

Feng Yuan still smiled and nodded, and said, "Well, okay." ”

Guan Zheng got straight to the point and said, "I called you this time because I want to know if you have anything to say about this arson case?" ”

"I was not involved in the arson."

Guan Zheng nodded and said, "I hope so, too, but now the evidence in our hands is very unfavorable to you." So I'd like to know what kind of call you got that afternoon. ”

"I'm sorry, I can't really say this because it's important for the person concerned."

"The parties? Who is this party? ”

"I can't really say that."

"How important is this person to be so protective of you?"

"I didn't cover it up, I just hid what I didn't want to say. As for this person, it's just as important as the two of you. ”

The conversation was not smooth, and Guan Zheng had no choice but to say: "Then I have to wronged you to stay here for 48 hours." I'll find all the evidence to get you out of here. ”

"Thank you for believing in me, and I believe I won't let you down."

Guan Zheng nodded, opened the door, and listened to Feng Yuan say, "Can I ask you for a favor?" ”

Guan Zheng turned his head and asked, "Please speak, I will do my best within the scope of my ability." ”

Feng Yuan said: "Help me convey to Wang Weiqi and ask him to check the Qipu generator in the laboratory again, and be sure to turn off the PCR machine." ”

Guan Zheng responded: "Okay." Then he turned around and walked out of the inquiry room, and his heart instantly became steady.

Xu Jiuyan asked: "Why did you tell Wang Weiqi like that, you were so relieved, did you know something?" ”

"The murderer is known, of course it's easy."

"Hurry up, what the hell is it."

Guan Zheng said: "The Qipu generator is a laboratory glass instrument invented by the Dutch chemist Qipu to produce hydrogen and other gases. A Qipu generator is a type of gas generator, also known as a Qili gas generator or hydrogen generator.

It is often used in experiments with the reaction of solid particles and liquids to produce gases. A typical experiment is the production of hydrogen from dilute hydrochloric acid and zinc granules.

Dilute hydrochloric acid is a chemical, which refers to the ignition of arson, and zinc particles refer to the human heart, hoping that he can wake up. The biggest feature of the Qipu generator is that it can be used immediately, which is to tell Wang Weiqi to stop evading, and he can get good results.

A PCR machine is an instrument that replicates DNA fragments more than a million times, which is to let Wang Weiqi know that he must not continue to make mistakes, and once he takes a wrong step, his life will be ruined. ”

Xu Jiuyan asked, "Then what now?" ”

"Do you remember, when I asked her who this person was, she said that she had the same status as us, and we were all her students, indicating that this person should also be her student."

"But she has been teaching for many years, and there are so many students, how can we check."

Guan Zheng said: "If you think about it the other way, she teaches a lot of students, but she remembers you when she sees you, which shows that she cares very much about people who are more active in the class, such as class representatives and class leaders."

This is also in line with the characteristics of human memory, always remembering things that are impressive for a long time, but this person must not be her previous student. ”

"Why, she's so good to her students."

"If it was a previous student, I wouldn't have thought of calling her, because a student has many teachers, and everyone's feelings are different, and Teacher Feng is not necessarily the favorite teacher.

On the other hand, students will always have a priority with their teachers, and they usually don't ask teachers for help, unless they have been dealing with them a lot recently and have a deep friendship. ”

"Could it be Wang Weiqi?"

"No, if it's Wang Weiqi, then the two of them won't have a consistent alibi."

Xu Jiuyan nodded and said, "Then let's check her latest batch of graduates and the students in her current class." ”

Jiuyan quickly flipped through the computer, and there were hundreds of search objects. Xu Jiuyan looked at Guan Zheng with blank eyes and said, "There are so many people, you have to check them one by one!" ”

Guan Zheng shook his head and said: "No, in terms of gender, it should be a girl who takes the initiative to ask for help or is dependent on the teacher, and the boy loves face and will never ask a female teacher for help."

Her grades should be in the upper middle range, and it is very likely that she will study in Nanyi No. 3 Middle School in high school and Nanyi University in college. It should not be a coincidence that she went to the shopping street on the day of the crime, and it is possible that she worked part-time there. ”

Xu Jiuyan put the screening conditions in, and soon a person appeared, Xu Jiuyan sighed: "There is really such a person." ”

"Then don't look at who the master is!" Xu Jiuyan couldn't wait to click on this person's information, and couldn't help but be surprised, and said, "She turned out to be Wang Weiqi's girlfriend!" ”

Xu Jiuyan sighed and said, "This is very bad for us, and it is very likely that she will not help us." ”

"I'm going to send you out, invite her to tea, and watch a play called Bitter Meat Trick by the way."
