Yu Fan and Chen Jieyang stood outside the classroom, quietly waiting for Dean Wu to finish class.

The bell rang for the end of class, and Dean Wu announced the end of class, but there were still many students who came forward to ask Dean Wu questions, and Dean Wu was very patient and kind to answer them one by one.

Dean Wu's assistant also came down from upstairs, apparently to help Yu Fan inform them of their visit.

Assistant: "Are you just standing outside all the time?" ”

Chen Weiyang nodded.

The assistant had a proud smile on his face: "Dean Wu is from chemistry, and our chemistry department is also the best department in the Faculty of Science. ”

After that, everyone's eyes fell on Dean Wu again, and the assistant continued: "I used to think that chemistry was a boring discipline, with endless equations to memorize and reaction mechanisms to remember, but Dean Wu was able to bring these to life, very vividly, for Dean Wu, chemistry is not a discipline, but... ”

"It's art." Yu Fan interjected, his face was also filled with a strange smile, as if he was very happy in his heart, but he pretended to be calm on the surface.

Assistant: "Yes, art, that's pretty much what it means." ”

After about ten minutes, the last student to ask a question left, Dean Wu took off his glasses and pinched the Qingming acupoint with his hand, it seems that standing for such a long time, and the passionate teaching is indeed very physically exhausting, and they are all such old people.

The assistant took Yu Fan and Chen Jiaoyang into the classroom. Assistant: "President Wu, two comrades from the public security system have come to you to learn about the situation. ”

Dean Wu put on his glasses again, looked at the two of them respectfully, and said kindly: "Two little comrades, what can I do to help?" As he spoke, he began to tidy up the experimental table, still so meticulous, even the angle of the reagent bottle label outward.

Chen Jieyang spoke: "Hello Dean Wu, my name is Chen Jieyang, I am the person in charge of the task force, and this is my consultant, Yu Fan. That's right, I took the liberty to come here today to ask you about a teacher in the Department of Chemistry of our Faculty of Science. “

Dean Wu smiled and said, "There are so many teachers in our college for so many years, I may not remember every single one, but I should know that you are from the Department of Chemistry, who do you want to ask?" ”

Chen Xiangyang: "A teacher in his fifties and sixties, with a full beard and a long face. We don't know his name, he is terminally ill and left the unit only a few years ago. As he spoke, Chen Jieyang showed the information to Dean Wu.

Dean Wu looked at the information carefully, frowned, and said, "Are you looking for Teacher Chen Tizhou?" ”

Chen Jieyang: "Oh? Do you remember him? ”

Dean Wu: "Of course I remember, he is our star professor here, Lao Chen doesn't like to teach students very much, and his temper is a little weird, but he is the kind of genius who does research, before leaving, one of his patents on 'fungicide' also won an international award, but unfortunately he left in a hurry without even receiving the award." None of us know why, I don't know he has a terminal illness, but if you say that today, if he really has a terminal illness, then the reason for resigning is reasonable. ”

Yu Fan: "Is the international award for fungicides you are talking about "Fungicide Double-chain Slow Release Technology"? ”

Dean Wu was a little surprised: "It seems that Mr. Yu Fan has heard this?" ”

Yu Fan continued: "I happen to be a person in a related industry, so I have heard of it, and at that time I knew that the developer of this technology also invented a more advanced 'bacterial limit challenge' experimental process, and we have been using his experimental specifications all the time, and he is a professor of our XA Jiaotong University for a long time." ”

Dean Wu was very pleased: "In the eyes of Mr. Fan, this person is not only an industry person, but also a person who can see through the real doorway inside." ”

Yu Fan was a little embarrassed: "Where, I'm getting an axe from the class." ”

Chen Jieyang then asked: "Do you know where this Professor Chen Tizhou has gone after he left his job?" ”

Dean Wu: "I don't know, his personality is very eccentric, and no one will say anything." Maybe geniuses are a little paranoid. In terms of scientific research level, Lao Chen is actually far ahead of me, but it's a pity, hey. ”

It seemed that the clue that was finally found was broken again, Chen Jieyang was a little disappointed, and then asked: "Can we take a look at Professor Chen's workplace before he left?" Also, we would like to see Professor Chen's archive. ”

Dean Wu happily agreed: "Of course there is no problem, I will take you there personally." Assistant Ma, you go to the archives room and take out Professor Chen's file, and bring it to the two comrades later. The assistant nodded and left first.

Dean Wu also happened to pack up the experimental table, and led Yu Fan and Chen Jiaoyang upstairs to Professor Chen's original office.

On the way, Yu Fan asked curiously: "Dean Wu, we just listened to your class at the door, it was very vivid, has your class style always been like this?" ”

Dean Wu laughed: "I, I belong to the kind of people with mediocre qualifications, I don't have any talent in scientific research, and the people who can really make scientific research results must be talented and hard-working people." This point, Mr. Yu Fan, you should have some understanding. ”

Yu Fan nodded. Dean Wu continued, "Therefore, I have put all my energy into research and teaching, and how to efficiently transfer knowledge to the next generation is the direction of my lifelong research. Therefore, I will do how students absorb knowledge. ”

After hearing this, Yu Fan nodded even more admiringly: "Dean Wu, there are not many people like you who specialize in research now. “

Dean Wu waved his hand: "This is wrong, for teachers, I think that teacher morality has never been annihilated, but now there are more and more affairs on university professors, it is difficult to choose, and they can't help themselves." Only those who have good self-regulation and are willing to give up can squeeze out the space for their hearts to breathe. ”

Soon, the three of them arrived at Professor Chen's office, which was on the third floor. Dean Wu called out to the staff of the security office to open the door. As soon as the door opened, there was a strong smell of books.

Dean Wu: "Since Lao Chen left, this office has been completely used, and in recent years, there have been fewer students who want to study chemistry, and there are fewer teachers who teach chemistry. Also, chemistry is hard, dangerous, and more importantly, not profitable. ”

Yu Fan took a closer look at this office, the office is about 20 square meters, as long as it is flat, it feels like there are books or materials piled up. Sunlight shines through the curtains in the room, which takes on a yellow tone. It's like an old photo from a movie memory. Chen Jieyang opened the curtains, and in the bright sunshine, the dust was particularly conspicuous, and Chen Jieyang couldn't help but chase away the ash in front of him.

Dean Wu: "Then you two will look at it first, and if you have anything unclear, you can find my assistant or find me." ”

The two thanked Dean Wu and began to carefully search this office full of age.
