Professor Gu's study is very messy, there are books everywhere, there is an old rattan chair in front of the desk, and there is a four-legged stool used in ordinary schools next to the rattan chair, Zhao Qiang is sitting on this four-legged stool, Professor Gu takes off his glasses: "Zhao Qiang, I have read your previous files, and the results are indeed unsatisfactory." ”

Zhao Qiang still said matter-of-factly: "Yes, Professor Gu, I am afraid that I will not have such good luck again, so I refused to agree to study your graduate school before, you don't have any opinions, in fact, I am still worried at this time." ”

Professor Gu smiled: "What, do you still need me to find a test question to prove your own strength?" ”

Zhao Qiang smiled, this is not necessary, as long as Professor Gu does not dangle in front of his eyes, he has the help of Xiaowei and is not afraid of any test, that is to say, he has 'strength', and he will have to 'guide' Professor Gu in a while' material things, so now he must show some courage.

The confidence on Zhao Qiang's face suddenly made Professor Gu very satisfied, and he continued: "I asked you to come in to ask if you have any ideas about studying for graduate school, and if there are any difficulties at home that need to be solved, I know that you have spent more time working in the past three years than studying at school, it must be limited by family conditions, if there are difficulties, I will do my best to help you." ”

It was true that there were difficulties before, but after that, it was much simpler, and making money was just a trivial matter, so Zhao Qiang said: "Thank you, Professor Gu, the difficulties at home have been solved." ”

Professor Gu smiled: "Yes, I have started my own company, and I will ask Xiaoya to send me a business card in a while." ”

Khan, Professor Gu heard all the words outside in the study, and I don't know if it will affect the image in his heart because of this.

"Since there is no problem financially, what is your view on graduate school, is there a certain direction?"

Zhao Qiang was secretly happy, this was Professor Gu guiding him to say 'a' material things, "uh...... Professor, I do have some ideas, you can take a look at this kind of thing first, I dug it up in the field of my hometown when I was in high school, and these appraisal certificates, of course, are the identification of private surnames, I spent my own money to find someone to test, there is no authoritative surname, and it is just for reference. ”

Professor Gu actually just wanted to ask Zhao Qiang if he had any interest in a certain direction, he liked to be guided by the interests of students, but he didn't expect to have an unexpected gain.

A black iron plate, no, to be precise, it should be an unknown substance, because the iron plate should not have such a density, heavy, it seems to be one or two times more dense than gold, and Professor Gu can't hold it if it is just a small piece.

Professor Gu weighed and observed while taking the A4 printing paper, which was part of the analysis results of this substance, "The composition of ferroalloy is majority, but its hardness has far exceeded that of ferroalloy itself, so it is different from normal ferroalloy, and the hardness measurement data is not inferior to boron carbide, and in some cases even far beyond the surname of boron carbide." ”

Zhao Qiang also made up for the relevant knowledge, boron carbide is simpler, also known as a tetraboron carbide, the molecular formula is B4C, commonly known as artificial diamond, used in hard material grinding, grinding, drilling, etc., in addition to a more important use, in the arms industry can be used as a manufacturing gun nozzle, can also be used as a ceramic coating for warships and helicopters.

Zhao Qiang patted Professor Gu's ass on the side: "Professor, you should understand at a glance, I'm confused, I've been thinking about it for the past few years, what the hell is this, I'll sell it as iron, I'm afraid of losing money, when I sell copper, and no one will collect it, when I sell it for gold, I'm afraid of being scolded, if you can help me solve this long-standing problem, I can sleep soundly at night." ”

Professor Gu was amused by Zhao Qiang's several metaphors: "You little guy, you look very honest, and you talk about witticisms in a string, this should not be steel, even if the main ingredient is but there must be another substance in it, because the proportion of steel is not so large, but your analysis report is too general, I need to re-sign it." ”

Zhao Qiang nodded and agreed: "Yes, professor, you are a well-known expert in the physics world, if you identify it, you will definitely be able to see it through, I guess there may be a mysterious substance in it, maybe it is it that causes the ferroalloy to become so hard and heavy." ”

Professor Gu nodded: "Your guess is also correct, but no one can say for sure until my analysis results come out, this item is very precious, I can just take some samples, and you will keep the rest." ”

Of course, Zhao Qiang doesn't care about this scrap: "Since the professor said that it is precious, it is safer and more useful to put it here than in my hands, but you know that I have no fixed residence, and it is impossible to carry such a heavy thing with me all the time, so it is more suitable for the professor to be its master than me, isn't there a saying that the sword is given to heroes in ancient times, the professor is a leader in the physics world, and only you can study it thoroughly, so I want to give it to the professor you." ”

Professor Gu laughed: "You, you look honest, but in fact, you are also cunning and great, okay, since you said so, I will not live up to your trust, I will accept it, and I will notify you as soon as there is a result." Professor Gu said as he played with the black leftovers, looking at his demeanor, this seemed to be the best gift for this year's students.

Zhao Qiang knew that he could only 'pull' Professor Gu today, and if he said more, it would be easy for him to be suspicious, so he should wait for him to personally identify the results before further guiding him to move closer to the manufacture of 'a' substances.

"Professor, this is a gift from Xu Xiaoya and me, I hope you can use it." Zhao Qiang took out the copper paperweight and the root carved pen holder.

Professor Gu did not refuse, smiled and took it, the copper paperweight on the table and the old rattan chair complemented the truth, coupled with the simple and original pen holder, it is indeed very charming, completely in line with the atmosphere of the study.

Professor Gu took a few glances at the gift and felt a sense of relief, he kept nodding and said: "These two things are good, much better than the jade and gold sent by your four senior brothers outside, Zhao Qiang, call me teacher in the future, 'Professor' is a little outstanding." "This time, the sycophant was beneficial, and it immediately brought the relationship between Zhao Qiang and Professor Gu closer, and of course that piece of leftovers also contributed to it.

Zhao Qiang will definitely be polite when he should be polite, but he will definitely not be polite when he shouldn't be polite, "Yes, teacher." ”

Professor Gu looked at the strange black matter again, he had a wonderful feeling, there must be some kind of substance unknown to human beings, if you can find and understand it, it will be worthy of the physics that has been studied for so many years, for a while, Professor Gu's favor towards Zhao Qiang has increased by several levels, and it is he who has brought new hope to his research career.

Since this freshly accepted student has made himself 'rejuvenated', it is even more important to pluck him out, "Zhao Qiang, your foundation is still very thin, and your original major does not have too high requirements for physics, so you need to continue to absorb knowledge to enrich yourself." ”

Zhao Qiang replied: "Teacher, I am reviewing the university courses during this time, and I plan to spend one to two months reviewing them, and then I will study a certain direction with a focus, and I hope that the teacher will guide me." ”

Professor Gu nodded: "I can recommend you to read a few books first, I don't ask you to study in depth, you know a rough idea, and you will not be too unfamiliar when you transfer to the University of Science and Technology next year, and you will follow my research when the time comes." ”

Professor Gu said while going to the bookshelf to pick out a few books, about the basics of physics, and the elaboration and application of some new materials, it should be said that this is in line with Zhao Qiang's current goal, he can't blindly rely on Xiaowei, so it is urgent to learn a lot of knowledge related to the 'a' substance.

Bang, bang, bang, someone knocked on the door of the study with a finger, and a little girl poked her head in: "Dad, it's time to eat." ”

It turned out to be Professor Gu's daughter, Zhao Qiang took a look at it curiously, the little girl was eleven or twelve years old, but she developed quite early, alas, people who are engaged in scientific research generally don't have time to fall in love, so the child is young.

Professor Gu introduced Zhao Qiang: "This is my daughter, Gu Xuemei, it happened to snow heavily in the winter when her mother gave birth to her, and the plum blossoms in the yard bloomed, so she was named Xuemei, hehe, her surname is similar to her name, too introverted." ”

The little girl lowered her head a little shyly: "Dad......"

Professor Gu got up and patted Zhao Qiang on the shoulder: "Go Zhao Qiang, accompany the teacher to have two drinks, you can take the book, don't forget it when you leave in the study." ”

Gu Xuemei stared curiously at the book in Zhao Qiang's hand, with a look of disbelief in her eyes, which made Zhao Qiang very puzzled, what's wrong? Doesn't the little girl like her father borrowing books, then she should be careful to love Jane, don't fold the corner and miss the page for the teacher.
