"By the way, do you have an eyebrow for that gallium oxide paint now?" Academician Su asked Lin Yudao in the elevator.

Joke, how could Lin Yu, who had obtained the aerospace composite material package, not have eyebrows? He can even make a dozen materials that are more than five years old from the current one, and gallium oxide paint is one of them, but that's about it.

Lin Yu asked the system why there are only more than five years of materials in the current era, and it is completely possible to make materials that are more than many years old, but the words of the system still make Lin Yu silent.

"The host forgot again, reality is not science fiction, let alone fantasy, even if I distribute the material synthesis process to the host, but can the host find the corresponding equipment for synthesis?"

Front-end technology, this is an important factor that limits Lin Yu's play, if there is no such restriction, with the help of the system, which comes from the science and technology brain of an unknown number of years, it is estimated that human beings will be able to enter the stellar civilization in his lifetime, right?

Taranadi! Front-end technology!

This feeling of being able to see but not touch makes Lin Yu, a person who is obsessed with scientific research, like technology being locked by alien protons, knowing where the road ahead is, but he just can't cross it, and he wants to die.

"I already have an idea, but the material is something that needs to be done little by little in the laboratory, and I can't design it in my head like mechanical design, and finally make it to see where the problem is and slowly change."

"But after all, I am familiar with gallium oxide, and I have a hunch that I will be able to give you an answer within a week." Lin Yu didn't say too much, he could have made gallium oxide paint today, but the relevant materials should be accumulated little by little through experiments, and they can be made in one day and the properties are completely consistent, which is absolutely impossible.

This is also Lin Yu's painful realization, that is, when he was researching the fourth generation of semiconductor materials before, because his performance in Xu Ying's rented laboratory was too rebellious, he was suspected by Xu Ying more than once after coming down from the laboratory, whether he had found the research institute and secretly went to the experiment.

This also made Lin Yu alert, geniuses also need time to experiment and accumulate, as for why Lin Yu did not choose to confess to the Chinese officials that he had a future ultra-high-tech artificial brain in his head.

Lin Yu didn't think about it, but every time this kind of thought appeared, he would forget all about it, that is, the idea of handing over his brain to the country would always pass away, and he would forget what he was thinking just now.

On this point, it is necessary to explain that the system exists in Lin Yu's mind, whenever he has the idea of handing over the system, the system will release a special nerve signal blocker, as long as there is a key vocabulary such as "system handed over to the country", the system can detect the nerve impulse signal of the corresponding word, so as to release the nerve signal blocker, let him accept the next segment of the nerve impulse The neuronal cells are temporarily dormant, so that this idea will disappear.

Very dripping science!

This is to make it clear that the system does not want Lin Yu to hand himself over to the state for research.

"I believe you, I heard that you never disappoint, and you have a nickname called Yushen, right?"

Lin Yu was a little embarrassed, "Where did you hear this?" ”

"On the Internet", Academician Su looked at him with a smile, "By the way, what do you want to do after you get the materials, do you have an idea?" ”

"Reusable liquid rocket engines." Lin Yu said a noun.

Academician Su looked at him strangely, "Do you really have an idea?" Spacesuit-related, composite materials, you also have to make rocket engines, why are you researching rockets in different fields? ”

"What? Is it because I just told you that you should be my student, so you suddenly became interested in the major of aircraft design and engineering? ”

Lin Yuxin said, can I say that it is a system arrangement?

He nodded on the surface, "It's not just because you're old, but also because my roommate Wang Hong is also in this direction, so I'm a little interested." ”

Academician Su nodded, "You can decide for yourself, since I have given you the right to be free, then I can't restrict you, you can do whatever research you want." ”

Two men stepped out of the elevator.

Repeating yesterday's process, Academician Su introduced Lin Yu to everyone in the materials group, and by the way, asked him to join the rocket surface engineering technology group.

However, this time Lin Yu couldn't be a blockbuster like yesterday, but took two people step by step and began to study gallium oxide coatings.

The materials group is the largest group in the space center, with nearly 400 people, divided into different groups, and there are many groups in each group.

"What we want to study is gallium oxide, which has good heat resistance, and all we have to do is to find its optimal solution to better protect the safe launch of the rocket."

Lin Yu and two members went to the material center to obtain the corresponding materials, applied for a separate laboratory, and began to do various experiments on gallium oxide.

In this way, under Lin Yu's intentional control, the gallium oxide coating was finally made on the tenth day.

"Consultant Lin, didn't you say that it would be done within a week?" Academician Su said teasingly.

"Horses have stumbled, people have misses, I didn't expect this material to be quite difficult." Lin Yu pretended to scratch his head embarrassed.

"So now you want to apply for an ultra-high temperature experiment?"

Academician Su looked at the report that Lin Yu had just handed in, "I approved it." He picked up the black pen and signed his name.

Lin Yu walked out of Academician Su's office, took the application form that had just been approved, called his two assistants, and prepared to go to the responsible personnel of the Logistics Support Department to prepare the corresponding facilities.

Ultra-high temperature laboratories are special laboratories, and if you want to conduct experiments in them, you need to apply for approval in advance, and only after approval can you prepare for experiments.

After staying in the space center for eleven days, Lin Yu also basically figured out the various departments and routes here.

Therefore, he found the experimental equipment management office of the logistics department very easily, submitted the application form and instructions, and the personnel of the logistics department immediately mobilized to prepare for the ultra-high temperature experiment.

"Consultant Lin, do you think the gallium oxide coating we made can withstand ultra-high temperature experiments?" This is one of Lin Yu's team members, and his personality is more cautious.

"Don't worry, we made it ourselves, don't you know about its performance? Right, Advisor Lin. The other looked at Lin Yu.

"Don't worry, it's going to be fine." Lin Yu followed his words and comforted him.

For Lin Yu, the results of this experiment should be very different, although his system research institute does not have this kind of place to test ultra-high temperatures, but he has also created a high temperature of almost 2500 degrees Celsius through various means, and gallium oxide paint can easily withstand it.

So he was confident about this experiment!
