After the meal, Gu Yunxuan made an exception and did not rest, and took Lin Han and Gu Wei to the laboratory again.

Gu Wei obediently entered her room and didn't know what she was busy with, while Gu Yunxuan led Lin Han to the examination room again. Lin Han understood that this was because the teacher was not worried about the mutation of the virus cells in his body, and he had to check it again.

The results came out quickly, just like last time. Gu Yunxuan only saw a large number of black cells all over Lin Han's body, but he still couldn't decipher the structure and characteristics of these cells.

It's normal for Lin Han to think about it, the big octopus under the 10,000-meter deep sea doesn't know how many tens of thousands of years it has lived, if it can't be done, it is an ancient species, there is no precedent and no previous information, if you want to explore its cell structure, I am afraid it will not be a day's work, not to mention that that guy is already weird and magical.

Gu Yunxuan then came to Gu Wei's laboratory with Lin Han, pointed to the steel plate and said, "I see that you were so happy just now, you only cared about one and didn't care about the other. If you take a closer look, what's different about this steel plate? ”

When Lin Han heard this, he stepped forward and squatted down to carefully examine the inconspicuous black steel plate.

Gu Yunxuan asked, "What do you know, what kind of steel is the hardest steel in the world?" ”

Lin Han scratched his head and said: "High-quality steel that must have enough strength and good flexibility at the same time, probably titanium steel, molybdenum steel, etc., right?" They are generally used in higher technology fields and are very expensive to build. ”

Gu Yunxuan corrected: "Maybe my question is too narrow, because Xiaowei developed this piece of steel, so I just asked...... Let's put it another way, what do you know about the hardest substance in the world? ”

Lin Han was stunned and replied, "Or maybe it's a diamond?" Nothing beats the hardness of a diamond. ”

Gu Yunxuan nodded and said, "If you don't say an accurate answer, just say a more general answer, you are right; But if you want to be more truthful, the diamond you answer will not be accurate. It should be said that polymerized diamond nanorods are the more accurate answer. In fact, it is a collection of nanoscale diamonds, which are extremely compressible and are the hardest substances known to man. There is data that shows that this compressed nanodiamond is 100 times harder than the steel plate you just mentioned! It was also invented by humans, first born in 2005 in the Germanic kingdom. ”

Lin Han nodded thoughtfully, and looked down at the steel plate on the ground, as if he realized something.

Gu Yunxuan said, "Do you remember the gold bar you brought back?" Now that it's set that record, Vicky and I have calculated that any part of that gold bar is 5,400 times harder than a nano-compressed diamond! And even more! ”

Lin Han was shocked when he heard this, and remembered the scene that day when Gu Wei operated a high-strength imported alloy gear to cut gold bars...... Later, the gears flew apart, and I still have palpitations. After that, he also checked the gold bars with Gu Wei, and did not find even a trace of scratched fine lines, which shows that what Gu Yunxuan said today is absolutely true, that thing is really indestructible.

Gu Yunxuan said: "But you must also remember that the phosphoric acid solution that Gu Wei accidentally sprinkled later easily disintegrated the hard surface of the gold bar, right?" Lin Han nodded and said, "Yes, I thought that the smell of that thing was harmful, and I grabbed the little junior sister and wanted to escape." ”

Gu Yunxuan said: "This thing is definitely not a gold bar, what is the specific element...... To be honest, neither of my uncle and nephew was able to study the clues, and I asked my old buddy Professor Xue Changrong to help, but unfortunately he couldn't draw conclusions. ”

Lin Han was surprised: "Professor Xue...... Can't you confirm it? ”

Gu Yunxuan nodded: "So, this must be another strange thing after the bright stone piece, let's call it 'tungsten gold', of course, it's just a one-sided title, you don't have to take it seriously." Under the guidance of Professor Xue, Xiaowei extracted a small part of this tungsten gold with a phosphoric acid solution, and then incorporated a considerable part of the common iron element to create this steel plate. ”

Lin Han heard the clue, reached out and gently stroked the steel plate, except for the cold and hard tentacles, there was nothing strange about it.

Gu Yunxuan said what he was going to say in the end: "But Professor Xue has personally tested it, and the hardness of this steel plate is still 2,000 times that of the compressed nano diamond rod!" And the flexibility is 46 times that of gold! ”

The more Lin Han listened, the more frightened he became, and he raised his head sharply and said, "Teacher, what do you mean......"

Gu Yunxuan nodded and continued: "The ancients said that you can't have both fish and bear's paws. We know that the higher the hardness of the steel, the less flexible it will be; Conversely, the higher the flexibility, the hardness will inevitably be reduced. For example, a steel plate that is extremely hard will become very brittle under the violent impact, and a certain point of its surface will crack with a brush; Although the extremely flexible steel plate will not crack due to violent impact, it will dry up and deform because of the very poor ability to withstand gravity......"

Gu Wei came up with a smile and said, "Brother Lin, this baby you brought back is different, it is hard at the same time, but it also maintains a strong flexibility, so in all the experiments of Uncle Xue and me, the performance is perfect...... Uncle Xue exclaimed that he had never seen such a miraculous experimental effect in his life, and the innovation that this steel plate could bring was enough to shock the whole world! ”

Lin Han said blankly: "What innovation can it bring?" ”

Gu Yunxuan said unhappily: "The stupid boy won't go around again, let me remind you, aren't you going to make a car?" It's great that you can build a car and use that new battery as power, but in today's world, where traffic accidents are frequent and car accidents are fierce, the safety of driving a car has become a major issue that needs to be solved urgently! The tragedy of car crashes and deaths is staged all over the world every day, just imagine, if you produce a car crash beam, add this tungsten gold material, or even you do not hesitate to cost, the whole car sheet metal is added to this material......"

Lin Han's eyes flashed with a flash of sudden realization, and he exclaimed, "That is to say...... That is to say, there will be no loss of the car body, and those hellish car accidents will no longer pose a threat to people! ”

Gu Yunxuan said: "That's the truth!" However, in view of the fact that there are no more experimental results to support it, the answer we can get can only be said to be theoretically valid, and whether it has any effect or not still needs you to practice it yourself. ”

Gu Wei stuck out her tongue and argued: "Uncle, who said that there are no experimental results!" How many things have hit this steel plate, and where do you see it deflated and broken? ”

Gu Yunxuan said with a smile: "Silly girl, the steel plate is just a steel plate, it does not represent the finished car!" If you want to know the final result, you can build a car with your brother Lin, I believe that now you don't want to go, he has to cry and shout and beg you to go, right? After that, he squinted at Lin Han and was proud.

Lin Han heard the door again, he wants to engage in automobile manufacturing, in the core of these two technologies, whether it is the power system or the safety system, its fundamental guarantee must be traced back to Gu Wei's research and development, otherwise everything else is impossible. The little girl has invisibly become an indispensable "intellectual talent" for him, and Gu Yunxuan's reminder is really insightful.

Gu Wei didn't know what to do, and applauded and cheered: "Okay, yes, yes!" Brother Lin...... Will you take me with you? ”

Lin Han nodded, and suddenly bowed deeply to Gu Yunxuan again...... The mentor strategized, and thought of his own front at every point, but he opened the way and built bridges for him everywhere to escort him. This is no longer the kind of feeling of life-saving grace, Lin Han knows that he has exhausted his life's strength, and it may be difficult to repay the teacher's kindness.

Gu Yunxuan flashed away and waved his hand and said, "Here again and again, if you bow again in a while, will my old man's body be regarded as the end of the view?" Lin Han was stunned when he heard this, and then laughed with him.

The harvest of this trip was really beyond Lin Han's expectations. At the time of parting, he said to his teacher: "Teacher, I may have to go to France next week, except for some personal affairs, there should be only one thing left to play in the mountains and rivers, if the situation allows...... I want to take my little sister out for a walk, do you think it's okay? ”

Gu Yunxuan nodded hurriedly: "Yes, yes, it's too good!" If you can take her out for a walk, it will be a great merit! Maybe this child will be able to open his mind and change little by little. ”

Lin Han said: "Originally, I wanted to take you with my wife, but considering that you are now employed by several colleges, I'm afraid you can't get out...... If I take my wife alone, there will be no one to cook for you. ”

Gu Yunxuan nodded and said: "It's rare that you have this filial piety, next time, next time you have a chance, your master and wife will go together, this time you just take Xiaowei with you." ”

Lin Han said: "It's easy for us to say, but it's you, you're getting older day by day, those academic exchange meetings and hiring teachers, if you can push it, you can push it, I always feel that you are more busy when you retreat than when you don't retreat......

Gu Yunxuan laughed, got up and patted him on the shoulder and said, "It makes sense, I didn't want to open it, I always can't do without those academic seminars...... There's no way, I've been doing this all my life, I'm a little used to it, and I can't throw it away. Speaking of which, it's also me, an old man, who is stubborn, and with such an uncle, it is natural to have a super crazy niece...... We are the wrong strange Gu Wei! ”

The master and apprentice looked at each other and smiled. Gu Yunxuan kept sending Lin Han to the door, and then went back to rest.

Lin Han took a taxi and went straight to Legend Real Estate, he was afraid that the negotiations were not over, so he sent a text message to Jiang Junjie: I'm downstairs, what's the situation?

After a while, Jiang Junjie's phone called, and his voice was slightly excited: "Lin Banxian, we are done early!" Oops, I didn't expect the negotiation to be unexpectedly smooth, that guy Will Pedder is really unambiguous, what conditions I proposed, he almost agreed, and he almost kowtowed and called Dad, haha! ”

Lin Han snorted: "Of course, I didn't misestimate him!" In front of interests, everyone has to pretend to be grandchildren! Besides, the significance of this transaction is extraordinary, and he can't be careless, for fear of accidentally messing up. ”
