In fact, the two old gentlemen were able to maintain their current life and become very famous professors in the school and even in the country. Neither of them, in fact, is not the kind of person who is very pedantic.

It's like Lin Su's approach, although they don't particularly like it. However, they also know that there are many such practices in this day and age. As long as it doesn't hurt the interests of other people, it's something you and I want, and they won't care too much.

Therefore, they will accept Director Zhang's invitation today and come over to help Lin Su take a look at the manual they brought.

However, after reading this manual, they changed their minds. The preparation of this manual is indeed very good. They really can't stand it, a very talented person, for some reason they don't know, buy their own hard work.

Even, Professor Liu has already thought about it. After he asked about the manual, the real writer. He had to find this person and talk about it.

If the age is right and the identity is right, he will find a way to get this person to their school. He would act as a gentleman and teach this man systematic and esoteric mechanical knowledge.

If the person's age is not appropriate, or if there is a problem with the identity. He will also try his best to help the person and solve his difficulties. Then talk to this person on an equal footing, and when the two of them are fine, they can also talk about the knowledge of mechanics together.

But in any case, they couldn't stand it. Truly talented people have been replaced by others for external reasons.

Of course, Lin Su and Director Zhang didn't know what the two of them were thinking.

They didn't understand why the two professors, who were not particularly enthusiastic at the beginning, but had a good attitude, didn't understand why. At this time, it suddenly became so serious.

But their attitude had no effect on Lin Su.

Hearing Professor Liu's words, Lin Su glanced at him with some doubts, and then said, "I wrote this manual, where is it, and is there any problem?"

When the first manual was written, Lin Su had already verified the content on the manual. Later, the instruction manual was lost. When Lin Su was writing the second manual, although it was based on the content projected by the system in his mind, he almost copied it. However, for some minor problems that were not checked out for the first time, Lin Su also made some modifications. Therefore, Lin Su really didn't find out that there was anything wrong with this.

Or it can be said that this is already the highest level of content that Lin Su can come up with in the manual.

Hearing Lin Su's words, Professor Liu, whose face was not particularly good, became more serious at this time.

Although he has some disdain for what Lin Su did. But the impression he had in his heart of facing Lin Su was still relatively good. Elderly people like them like this kind of clean, well-behaved and clever children.

So in the beginning, he and Professor Lu were two people. I even thought about not taking the words too seriously, so as not to hurt the self-esteem of this little girl.

Even if Director Zhang can lead Lin Su over and take out this manual. It shows that Lin Su's knowledge of machinery should at least have some foundation.

But how old is this girl?

Even if she had a talent for mechanics, at her current age, she shouldn't have been exposed to too esoteric, mechanical knowledge.

Moreover, it can be seen from this manual. The writer has a very clear understanding of this model of CNC machine tools. This is not the knowledge that a child who has not been exposed to physical objects should know. That's why they were skeptical of Lin Su's words.

Lin Su's words were very sincere. However, in the sound of Professor Liu and Professor Lu, there is some sophistry.

This era is not like the era in which Lin Su once lived, the Internet is particularly developed. As long as you are interested in something, you can search for it online. Even if there is no way to learn systematically, there will be no shortage of knowledge to learn.

In this era, there is a particularly single way to learn knowledge. If you don't study it systematically, it's almost impossible to master that much knowledge. Although there are indeed geniuses in this world, the number of geniuses is too small.

Although for various reasons, the two old professors do not seem to be particularly serious in teaching over the years. But for those students who are willing to learn, when they are fine, they are still willing to open a small stove for them.

So, for the two old professors. One of them can't stand the loss of talent, and the other can't stand the young children, lying and hiding in front of them, in their studies, for their own interests. And at this time, Lin Su, in front of them, just committed these two taboos.

Although the two of them had a good impression of Lin Su at the beginning.

But because of this incident, the two of them's Lin Su's favorability is constantly declining.

At this time, Professor Liu couldn't care about anything else. He looked at Lin Su, his face became more serious, and even a little stern.

"Look at you, you're not that old this year, aren't you? I want to ask, did you graduate from high school? What university are you studying at now?"

Hearing Professor Liu's words, Lin Su said to him: "I didn't study in college, I graduated from junior high school last year, and I went directly to work in our machinery factory." ”

Hearing Lin Su's words, Professor Liu continued: "The manual you handed me is very well written. It can be seen that the person who wrote this manual has a very clear understanding of the model of CNC machine tools commonly used in our country. He also has some understanding of the internal structure of CNC machine tools.

And he has a very thorough grasp of this knowledge, so that he can analyze some of the knowledge about this machine tool so thoroughly. Let the reader even if he does not have basic knowledge of mechanics, he can solve some common problems of this model of CNC machine tool according to this manual.

I want to ask, you are a young girl, you have not gone to university, you have not studied the knowledge of machinery, and you just entered the machinery factory last year. How do you understand the knowledge of CNC machine tools so clearly?"
