"Haha, this pit is well buried, hum, this Japanese didn't know how many national treasures they had plundered from our Huaxia at the beginning, and now they want to establish diplomatic relations with our empire when they bring a few national treasures, but there is no door, these things originally belonged to our descendants of Yan and Huang."

Yu Liang has always been straight, when he heard Tu Xueli's words, he laughed happily and gave Tu Xueli a thumbs up, the empire obtained the star map on the Orion spiral arm and the secondary spiral arm from the Kalan Empire, knowing that the Beichuan galaxy is developing around some galaxies, it will encounter a civilization on the secondary spiral arm that is more powerful than the Karan Empire, and then there will be a good show.

Thinking of this, not only Yu Liang, but also everyone else had smiles on their faces, the empire does not dare to expand externally now, with the urine nature of the Japanese, it is estimated that it will definitely be crazy to enclose land in the universe at that time, maybe it will not take a few years to encounter a powerful civilization on the second spiral arm.

"Actually, the Japanese don't have anything worth noting, what I'm more annoyed about now is that we haven't made much progress in the research of warp engines, I estimate that it won't be long before we will have contact with other civilizations, and if the strength is not strong enough, we may not be hard to speak."

After laughing, Li Fu's face also showed a look of worry, the secondary spiral arm was very small, and the original powerful civilizations on the secondary spiral arm had also been constantly expanding externally, like the Karan Empire, which had never given up external expansion.

Although the location of the empire is close to the dark abyss, it is very remote, and there will be no powerful civilization to expand here for a while and a half, but after a long time, it will naturally come into contact with more powerful civilizations, and there will definitely be a fight between them at that time.

With the current level of science and technology of the empire, it is not that it will be afraid of that civilization, but even if it can win, there will be certain casualties at that time, and if there is no warp engine, the casualties will be even more heavy if you want to expand, the empire is not like the Karan Empire, the population is hundreds of billions or trillions, and it is full of confidence and is not afraid of consumption.

"Alas, it's difficult, my side is in charge of researching controllable nuclear fusion, and the temperature generated by nuclear fusion is as high as hundreds of millions, and now we have no other way to control such a powerful temperature."

Speaking of this civilization, Chen Bin also sighed, this warp engine not only needs powerful materials, but also needs strong power, and controllable nuclear fusion is the only technology that can provide enough power now, but controllable nuclear fusion can not be studied in a word.

You must know that the nuclear fusion reaction, which is a reaction that occurs on the star all the time, produces hundreds of millions of degrees of high temperature during the nuclear fusion reaction, and any material will be directly ionized at such a high temperature, unless it is a special celestial body such as a legendary neutron star and a black hole that can withstand such a terrifying high temperature.

Controlled nuclear fusion technology is also the technology that the empire is now focusing on, and the scientists of the empire have tried all kinds of methods, but there is still no way to control the hundreds of millions of degrees of heat generated by nuclear fusion.

"We have made some progress in theoretical research, and we have found through the study of massive stars that when the mass is strong enough, or the energy is strong enough, the surrounding space will bend, fold, distort and so on, of course, this mass must be large enough, or the energy is large enough."

Yang Yiping, who is in charge of space research, led the good news to everyone, space can be folded and twisted, which means that the warp engine is possible, and the use of powerful energy to exert influence on space can fold space, so as to achieve warp flight.

"Powerful energy? Without mastering controlled nuclear fusion, how can we produce enough energy to cause space to collapse! ”

Speaking of this, Yu Liang said dejectedly, this problem is going around and around, in fact, it finally revolves around the two aspects of energy and materials, so that these two aspects can be solved, and it is not far from making a warp engine.

"There are always more ways than difficulties, as long as we continue to work hard, we can always solve the problems we encounter now, it just so happens that everyone is free now, or let's go to the Imperial Academy of Science together to take a walk and have a look."

Li Fu was full of smiles, in fact, the empire's technology has developed so far, and it is almost possible to make warp engines, as long as Li Fu says the method of making degenerate materials.

At that time, a strong magnetic field can be used to create degenerate materials, and then controlled nuclear fusion technology can be studied by using degenerate materials and magnetic field binding technology, and with controlled nuclear fusion technology, a huge amount of energy can be created to drive a warp engine to fold space, so as to achieve warp flight.

……

In the space of the Centauri Galaxy, only 2 astronomical units away from Yanhuang, somewhere in the void, a huge space city lies in the void, brightly lit, but unlike the busy scene in other places, it is very quiet, and there are very few spaceships coming and going, but these spaceships are basically marked with the logo of the Imperial Academy of Science.

The space city is one of many research institutes under the Imperial Academy of Science, a materials science institute dedicated to the study of materials technology.

At this time, in this huge space city, after learning of the arrival of Li Fu, Yu Liang, Chen Bin and other veterans of the imperial scientific community, Yao Tianyi and Li Qianyu, the deans of the Imperial Institute of Materials Science, also hurried over.

"Lao Yao, have you been working too hard lately, why do you have a pair of dark circles under your eyes?"

Yu Liang saw Yao Tianyi's tired face, and said jokingly with a smile.

"It's not just dark circles, I don't know how much white hair has grown, I can't sleep well now."

Yao Tianyi shook his head helplessly, obviously in no mood to joke with Yu Liang.

"Lao Yao, Sister Li, don't put too much pressure on yourself, there are some things that you can't rush to come, or I think you can rest for a few months first."

Li Fu saw the gray hair on Yao Tianyi's head and looked tired, and then looked at Li Qianyu, this famous beauty among the older generation of the imperial scientific community was also tired now, and after thinking about it, he also knew that they were facing great pressure now.

The core of the warp engine is the material, such a huge pressure is on the shoulders of the two of them, it is conceivable that the pressure of the two of them is now, originally both of them cultivated Yuan Li, they should be energetic and have a good mental outlook, and it is really too much pressure to become like this.

"Alas, what's the use of resting, if you have gray hair, you can study the degenerate material, and it's worth it if my hair is all white."

Yao Tianyi shook his head with a smile, and Li Qianyu on the side was also very helpless with the same wry smile.

"Let's talk about your progress and methods."

Li Fu smiled, and while accompanied by them, he began to visit the entire Institute of Materials Science, and was ready to give them a point.

As a discipline that the empire has vigorously developed over the years, the Imperial Institute of Materials Science has received very sufficient funds, a variety of advanced equipment and instruments, and so on, and a variety of advanced laboratories, such as high-temperature laboratories, high-pressure laboratories, superconductivity laboratories, and so on.

"We have tried to use tens of thousands of standard high pressure forging materials, we have also experimented with countless alloy materials, and we have also used ultra-high temperature shaping material methods, in short, we have tried all the existing material forging methods, but none of them."

Li Qianyu took the words, her voice was pleasant, although she was more than 100 years old, she looked like a young woman in her thirties, with a graceful figure, uneven, even a wide white coat still couldn't hide her graceful figure, at this time her figure looked a little tired, and people looked like it, which made people can't help but want to hold it in her arms and love her.

"Have you ever thought of some new ideas, such as trying some new methods of forging materials?"

Li Fu nodded after listening, the more this technology develops, the higher the demand for materials, and countless new materials are also emerging in an endless stream, constantly emerging, but the method of forging materials has always been so much, and the method of forging materials at high temperature can be said to be the oldest method in human history, but now it can control the temperature more accurately and can make higher temperatures.

"New ideas? A new approach? ”

As soon as Li Qianyu and Yao Tianyi heard this, they immediately raised their heads, and there was some secret in their eyes, as the top scientists in the field of materials science in the empire, they were very proficient in all aspects of material technology, and they couldn't be clearer about those methods to make those materials, etc.

"Yes, for example, the use of light to create materials, the use of magnetic fields to create materials, the use of space to create materials, the use of radiation, rays, etc., when we engage in research, we should not be limited by everything in front of us, and our thinking can be more open."

Li Fu smiled and nodded, in fact, he could have told them that it was feasible to use magnetic fields to forge materials now, but Li Fu didn't plan to do so.

Scientific research needs to be slowly and step by step to continue to explore and discover, if you tell the answer directly, it is completely meaningless.

It's like learning to do math problems, tell the answer directly, maybe you can make this problem, but if you encounter such a problem again, you will still do it next time, it is better to give some hints, let him slowly find the answer by himself, and finally solve it.

Only in this way can we better promote the growth of scientists, cultivate more outstanding scientists, and be truly useful for the future development of science and technology in the empire, which is why Li Fu has a plug-in, but he has rarely used it, because the road still has to rely on himself step by step.
