In the early morning of the next day, according to the confession clues of the Fire Dragon Master, Yu Fan and Chen Jiaoyang came to XA Jiaotong University to see if they could find some information about the "benefactor" in the Fire Dragon Master's mouth.

XA City is one of the cities with the largest number of colleges and universities in the country, and XA Jiaotong University is the university with the strongest comprehensive strength in XA City. With a history of 100 years, it is rich in science and humanities. It's a place where people come out on top.

The Department of Chemistry at XA Jiao Tong University belongs to the Faculty of Science, and the building of the Faculty of Science is tall and long, and the entrance is a long staircase, which is full of academic majesty.

Yu Fan and Chen Xiangyang entered the School of Science, and under the guidance of the staff, they directly found the office of the dean of the School of Science, but unfortunately the dean himself was not in the office. In today's university environment, many teachers and professors don't want to take classes after becoming officials, because classes are hard work, time-consuming and laborious, and it is far less expensive for them to do a project.

Assistant Dean: "Why don't you sit here for a while?" I'll be back when Dean Wu finishes class, and I'll let Dean Wu know. ”

Yu Fan looked at the dean's office, the whole office was well-lit, clean and tidy, the file code on the desk was neat, and there were several ornaments similar to atomic models on the desk, Yu Fan: "It's okay, let's go around, come back later, by the way, where is Dean Wu in class?" ”

The assistant dean thought for a second and said, "If I remember correctly, today is Dean Wu's experimental class, Dean Wu's experimental class is the most popular, and many students from other departments also come to audit every class, and the classroom address is 1-106." ”

Yu Fan: "Thank you very much, you can go first, we will call you if there is anything." ”

After the assistant left, Yu Fan and Chen Jiaoyang went downstairs to find classroom 1-106 while dangling.

On the way, Yu Fan asked Chen Jieyang: "Why don't we go directly to the people from their chemistry department?" Isn't that more straightforward? ”

Chen Xiangyang smiled: "You don't understand, investigate and collect evidence, find the big leader first, get the support of the big leader, and the little ghosts at the bottom will do things honestly, and if you want to use the archives or something, only the big leader has the authority." ”

I see, Yu Fan nodded.

1-106 is a spacious chemistry classroom, the classroom is full of glass windows on both sides, everything inside is so clear, I see that the classroom is overcrowded, a classroom that can accommodate 100 people, there are 130 people seated, and this is not an open class.

Seeing this scene, Chen Jieyang couldn't help but quip: "My God, there are so many people, wouldn't it be answered for others and sneak away without being discovered?" We had 30 people in a class that year, but we actually went to 13 of them, and I had to answer for two of my classmates, which was really difficult. ”

Yu Fan ridiculed Chen Jieyang: "Being able to come to class with so many outside students shows that Dean Wu's class is good, and there will be students who want to skip class?" Tyrannical creatures. ”

Chen Jiaoyang touched his ears and said, "It's the same." ”

There is an old man standing on the podium of the classroom, if nothing else, this is Dean Wu, he has silver-white hair, although he is very old, but there are still many hairs, and the hair quality is also very good, the silver-white hair shines in the light, as if it is on a brightener, this kind of light gives people a kind of affinity and majesty of a wise man.

Dean Wu was wearing a white coat, he looked tall and tall, he cleaned himself up very cleanly, with a pair of black-rimmed glasses and a bustling white beard.

There are many reagent bottles and beakers on the table on the podium, and Dean Wu is doing teaching experiments for the students.

The students in the audience listened attentively to the teachings of this wise man. Yu Fan believes that the school is a sacred place, this place does not have too much utilitarianism, only selfless knowledge inheritance, in fact, Yu Fan's dream was to be a teacher, a stable life, spread the seeds of knowledge, peach and plum all over the world.

Although Dean Wu is old, but the action is very steady, pick up the reagent bottle, the hand does not tremble, Dean Wu's operation is very rigorous and delicate, after taking the reagent, put the reagent back in place, turn the reagent bottle to the label exposed outside, the titrator eyes level. Every detail shows Dean Wu's serious style.

Yu Fan recalled that when he first learned formula blending in the factory, Yu Fan's master also taught Yu Fan that chemistry must be rigorous, and the difference is a thousand miles. Once Yu Fan was responsible for mixing a tank of 5 tons of liquid, but because of negligence, an additive forgot to add, because the additive only needs to add 100 grams, Yu Fan thought at the time, just 100g of things are dispensable, after all, compared with five tons of liquid, whether there is this 100g has little impact. As a result, all 5 tons of finished products were scrapped, causing huge losses to the company. Later, Yu Fan's master criticized Yu Fan fiercely: "Chemistry is very rigorous, you are young and self-righteous!" Do you think that 100g is dispensable? If it's really dispensable, why do we have to have it in our formula? The smaller the amount of reagent, the more important it is!! A true master of chemistry must understand a truth: 'Details determine success or failure'!! “

Yu Fan recalled the teachings at that time and whispered to himself: "Yes, details determine success or failure." This is true of chemistry, and the same is true of life. ”
