I have a chat group.

[Han Duoduo: Why don’t we give it a try? The level of technology in our world is higher than yours! ]

[Yang Dong: I can give it a try. The technological level of our world is also good, much better than yours. Moreover, the technological level of our world in the future is visible, unlike your world. I cannot see the technological level of your world. Your world seems a bit absurd to me.]

[Han Duoduo: I feel the same way. Your world is indeed a bit absurd. I simply cannot understand your world. Even before I became a martial god, I could expand the underground space and create small worlds, but I still cannot understand your world.]

[Aurora Lane: Actually, I can’t understand it either. After all, your world is a little too fantasy. Our world is science fiction, and your world is fantasy. These are two different systems.]

[Gao Wenfeng: It seems like the three of you have been together for a while. Are you discussing the development of technology? Miss Aurora's Avalon spaceship must be very useful to you.]

[Han Duoduo: It is indeed very effective. The Avalon spacecraft in Miss Aurora's world can reach a flight speed of 50% of the speed of light. This technology is very useful to us. In addition, they also have the technology to synthesize food. The food that the male protagonist eats on the spacecraft is all synthetic, which is much more delicious than dried earthworms.]

[Yang Dong: The technology in Miss Aurora's world is indeed very useful, but most of the technological products in their world are finished products, not technologies, which is a bit troublesome. Even if we reverse engineer them, we can't study those things.]

[Aurora Lane: I'm sorry, our spacecraft was the first to go to Home Planet II for pioneering, so most of what we brought were finished products. As for technology, we didn't store much. Even if we did, it was outdated technology. We wouldn't be given the most advanced technology, but that technology is enough for your world! ]

[Professor Oak, there is no problem with this. Didn't I release Rotom? That's a Pokémon that can fuse with any technological product. Rotom is still very useful. They have already controlled the entire spaceship. They can take out all the information on the spaceship. And 3D Dragon has also entered the network of Miss Aurora's world. They can connect to the database on Earth. We just need to wait for some time.]

[Yang Dong: Wait? How long? Their world has no space information transmission network, no quantum communication technology, and no proton communication technology. Their world's space information transmission technology is a bunch of shit, not even as good as my mother. My mother can at least use the sun to amplify the signal, but their world can't even do that.]

[Han Duoduo: Now that you mention it, it suddenly occurred to me that our sun might have also been dug up in this way?]

【Zhang Sanfeng: It should be impossible in known civilizations. Generally, the attacks on the sun are either energy absorption or light particle attacks, which cause the sun to age rapidly. This kind of thing should not be done by alien civilizations. It is very likely caused by some special energy in the universe.】

[Gao Wenfeng: I agree with this. Stars can generally be used as anchor points for cosmic jumps. In the universe, we cannot determine the direction based on the constellations on Earth, because those constellations do not exist in the universe. We can only determine the stars one by one. At the same time, we can also determine that the wavelength of each star is different, and we can use this to navigate our spacecraft.]

【Zhang Sanfeng: Not only can it be used for navigation, but it can also absorb energy. In the future, the energy used by spacecraft in the universe may not come from the energy on Earth, but directly absorb the energy of stars, because the energy of stars is almost infinite. Besides, don’t we have Dyson spheres? Although a star-level civilization can never use the resources in its own galaxy to create a Dyson sphere, what about those civilizations that control the entire galaxy? Will they do this? Will they create a Dyson sphere and use it as a spacecraft energy replenishment station?】

【Gao Yuliang: This should be necessary. Besides replenishing the energy of the spacecraft, the Dyson Sphere will also be the prerequisite for another technology, that is, a star-class computer. Don’t the civilizations of the Angel, Demon, and God Box in the Super Seminary have star-class computers? They use stars as the energy source of computers to make them perform large-scale calculations. One computer can manage civilizations in several galaxies. These things should also be necessary for advanced civilizations. Moreover, they will not only prepare one or two computers, but many computers, not only for insurance, but also for multi-project applications. This technology should exist, so generally speaking, no one would do such a thing as destroying a star system.】

[Draco Malfoy: I also think it may not be man-made. It is very likely affected by other galaxies. Will the Milky Way collide with other galaxies in tens of millions of years? This may be the problem that occurred before! ]

【Zhang Wei: It shouldn’t be possible. If there is a problem, it can’t be a problem with one star on Earth, it should be a problem with multiple stars at the same time. I think the solar crisis in Han Duoduo’s world is man-made, but the other party’s civilization level is much higher than theirs. It feels like humans facing the singer civilization.】

[Yang Dong: Can you please not mention that civilization, that civilization's dimensionality reduction attack slice, and use it as a special tool for garbage disposal? This is not a good thing! ]

【Han Duoduo: Yes, don’t talk about these things. If you talk about them, I will feel even more uncomfortable. Dimensionality reduction attack, this is something that can really destroy the world.】

[Draco Malfoy: I don't like dimensionality reduction attacks either. In my opinion, your worlds are not as good as Warhammer 40k. At least in that world, no matter how humans play, there will be a subspace to back them up. There will be no such thing as eternal death, nor will there be such things as star destruction. Because in the Warhammer world, they want people to survive, not to die. So their worlds are better than yours. At least they can back them up for some things! ]

[Aurora Lane: No, why did you guys turn the issue to this direction? Aren’t we discussing technology? ]

[Yang Dong: It’s good that they can discuss these things. You have to understand that although they know a lot of knowledge, and even have all the knowledge known to mankind in their brains, knowing does not mean they can apply it. They can only say that they are scientific dictionaries, but they cannot say that they are scientists. If you ask them for all the scientific explanations, they can answer as long as there are some things in their database, but if you ask them to conduct specific research, sorry, they can’t do it because they don’t have the brains to do it.]

Yang Dong knew very well that although these people in the chat group had purchased a lot of knowledge and downloaded it into their brains, doing this knowledge only expanded their knowledge and accumulated their knowledge reserves. As for asking them to do real scientific research, they could not do it because they only knew science. At this time, Yang Dong was looking at the space elevator in front of her with a look of surprise. She did not expect that in the world of Under One Person, a space elevator could be made so quickly.

Beside Yang Dong, Aurora and Han Duoduo were also looking at the space elevator.

"I never thought that this world would build a space elevator so quickly, and the location chosen is exactly the same as our world, but this space elevator is bigger than ours!"

Han Duoduo looked at the space elevator, then looked at the people nearby, also with a look of surprise on her face, because the space elevator in this world is two times larger than that in their world, and can accommodate at least 60 cabins going up and down at the same time.

Aurora looked at the holographic projection with his own bracelet, "This space elevator is not big. It is not as big as the space elevator we are going to build on Home Planet No. 20. On Home Planet No. 2300, we plan to build a space elevator with a diameter of kilometers. Otherwise, many things cannot be made. The space technology of the human world in is not what you can imagine in your world. Although you want to play the Wandering Earth plan and build a space city plan in the future, these things exist in our world, and Home Planet No. is only the second planet of the Home Colonization Company. The Colonization Company had the first planet before. In our world, space colonization has become a new field of capital investment and the development of planets has a great impact on companies and humans."

"Human civilization has developed more than 50 planets in the past. Many of them are habitable planets, but some are mineral planets. In order to develop the unique minerals on those planets, humans will colonize those planets. When colonizing those planets, it is necessary to build large airports. Large airports must have large enough space elevators to transport supplies. Therefore, this space elevator is just normal in our place, and some companies will make it themselves."

"But isn't your world overpopulated? Where does all this extra land come from?"

Han Duoduo was a little confused. Wasn't it said that the world's population in 2300 would be too large and the Earth would not be able to accommodate everyone?
Why are there so many immigrant planets?

Aurora said, "Isn't this normal? The Avalon is a large spaceship, but it can only accommodate more than 5000 people. How many people are there on those dozens of planets? Each planet has at most 200 people. There are only a few hundred thousand people on those dozens of planets, but the human population is close to 200 billion. A few hundred thousand people compared to billion is not a drop in the bucket, but better than nothing."

Aurora can be considered an aristocrat in the world of space travelers, because Aurora's father once won the Pulitzer Prize and was famous on Earth, and was already considered a local dignitary.

So Aurora knows a lot, more than those people on the spaceship.

Yang Dong listened to what the two said without any change in his expression, because he knew very well that the technological levels of these two worlds were stronger than their Three-Body World!
The most important thing is that the spaceships in the Aurora world have 50% of the speed of light. The Trisolarans do not have such fast spaceships. Yang Dong has always hoped to obtain the technology of this world, so he would not offend them if possible. Moreover, Yang Dong is still busy learning the techniques of the Divine Machine in the world of Under One Person.

The Divine Machine Hundred Refinements was truly amazing. Yang Dong watched how those who knew the Divine Machine Hundred Refinements could quickly build a space elevator. No matter what kind of thing it was, as long as there were enough raw materials, they could use the Divine Machine Hundred Refinements technology to manufacture it, and then use this technology to install it. The entire space elevator manufacturing process was like stacking blocks, except that those blocks were made by hand.

"Yang Dong, do you want to ask Gao Wenfeng about this matter? He should be able to help you get in, right?"

Han Duoduo thought of Gao Wenfeng because he knew what Yang Dong wanted to do?
"Shen Ji Bai Lian? Shouldn't this thing be put in the chat group? Isn't there already a way to practice Shen Ji Bai Lian in the chat group?"

Aurora knew about this, but he learned it in the chat group. It was just that Yang Dong didn't want to learn it that way, because Yang Dong knew very well that learning that way would cause big problems.

"The Divine Machine Hundred Refinements in the chat group. I don't plan to learn that thing. Although I learn it quickly, I can't learn other things. Now look at using the Divine Machine Hundred Refinements to make carbon fiber. Can you do it? Without using the Divine Machine, can you make refractory materials with Hundred Refinements? This is a material that can withstand the burning of stars! Who can do it with existing technology? Don't talk about your world of space travelers. What you have in that world are only entities, not technology. Your world does not have the corresponding technology, and a spacecraft will not be equipped with such cutting-edge technology for you."

Yang Dong knew very well what level of civilian spacecraft was. Although civilian spacecraft could reach 50% of the speed of light, which seemed very powerful, military spacecraft must have reached sub-light speed or super-light speed, otherwise the Home Company would not be able to broadcast the promotional video of Home Planet No. .

"I know all of what you said, but what's the use? I have a full set of technologies in my hands, and you have seen those technologies. As long as you get them, you can use them. Moreover, the Avalon spacecraft not only has 5000 passengers, but also several large cargo warehouses that store all the information and materials for a new space colony base. With these things, we can naturally complete the migration to the planet. We just need to find those things, upload them to the chat group, and make a large number of copies. There is no need to be so strenuous!"

Aurora thought everything was very simple, but Yang Dong's mouth twitched. If things were really that simple, that would be great. Science is about tracing back to the source, not knowing the facts without knowing the reasons. (End of this chapter)
