The two satellites were shot down for unknown reasons, which greatly stimulated Li Quan's curiosity.

First of all, a premise: this is an otherworld, there is no need to be surprised when anything happens, everything is possible.

Li Quan believes that this kind of thing is definitely not a coincidence. He could see the two lightning bolts clearly, and even the angles at which they were activated were exactly the same, and there must have been something in the sky that he couldn't see.

He must find out,

This is his plane, how can there be something unclear on his head peeping at him, even if it is really the so-called god of the Game of Thrones world, he has to go up and say hello first.

It will definitely not work with earth technology again. Without saying a word, Li Quan directly purchased a stealth reconnaissance drone on the plane market, which was a thousand years ahead of the earth. Because I don't know what the thing above my head is, what type it is, who is manipulating it, whether the other party has been paying attention to him for a long time, whether the other party is kind or malicious, etc., I don't know. For the sake of safety, I bought this super toy that costs as much as 30 million energy coins, which is absolutely unaffordable for ordinary plane merchants.

The streamlined stealth reconnaissance drone full of science fiction quickly rose into the air, like a feather under the breeze, rose up and entered a comprehensive optical stealth mode at the same time, and isolated all wavelength detection, only the microcontrol device on Li Quan's eyes could find it.

Li Quan stood on a steep cliff, looking at his toys expectantly like a model airplane, thinking about what would happen this time.

The stealth reconnaissance aircraft rose to the same altitude as the previous two rockets.

Nothing happened.

The lightning that shot down the rocket was unaware of the arrival of the stealth reconnaissance plane, allowing the stealth reconnaissance plane to continue to rise and fly out of the atmosphere at supersonic speed.

The aerial footage of the stealth reconnaissance plane was transmitted in real time to the microcontrol device on Li Quan's retina. He witnessed the moment the stealth reconnaissance plane flew out of the planet's atmosphere, and the sky seemed to suddenly go dark, and everything fell silent.

The starry sky is brilliant, and pitch black is the main color. Only the bright man-made building is so conspicuous. Li Quan saw the space building at a glance.

This is a space station, there is no doubt about it. The stealth reconnaissance plane approached, and it could be seen that the construction technology of this space station was very mature, and it was not at all the kind of tatters like the solar panels and iron barrels spliced by the countries of the earth. It's a real space building.

The overall scale of the building is not large, and the stealth reconnaissance plane soon transmitted back remote sensing data: about 500 meters long, about 400 meters wide, and about 200 meters high.

"Unexpectedly, at the head of such a backward world, there is an alien high-tech building! What the hell is going on here, and who built it? Is there anyone in there? Alien? ”

Li Quan stood on the top of the mountain, his vision already soaring into space with the stealth reconnaissance plane. Faced with such a scene in front of him, he couldn't help but have a whim, and he had a new view of the plane of power and power.

This stealth reconnaissance plane has a very high technology content, and there are many multi-functions that he can't understand, but it is very practical. Soon, some more data and images were passed to him. Seeing these pictures and data, Li Quan was shocked, he couldn't imagine that this plane still had so many secrets!

The stealth reconnaissance plane found a total of 6 identical space stations around the blue planet, and the remaining 5 were the same as the one in front of them, which were in various directions of the planet, forming a certain connection.

In addition, the biggest discovery is the data obtained by the stealth reconnaissance plane that has conducted a deep scan of this space in the past ten seconds. It's a sound star system with a total of five planets, with the exception of Westeros, a barren terrestrial planet, and the rest are gas giants. The most important thing is that the sun here is actually wrapped.

What does that mean? From the extremely clear pictures taken, Li Quan saw that the star in Westeros's star system was actually deployed with an artificial structure on the outside, like some kind of ring, layer upon layer.

Seeing this scene, he immediately thought of a term - Dyson ball.

"It's a Dyson ball...... I didn't expect it, I really didn't expect it! Li Quan looked up at the sky and muttered with a look of surprise on his face.

What is a Dyson sphere?

Li Quan is a scumbag, but he is particularly curious about the universe, and often reads some cutting-edge news of science and technology on the Internet. Part of what he knows about Dyson Ball is what he once saw in the news.

The so-called Dyson sphere is a theory proposed by an American scientist named Freeman Dyson as early as the mid-twentieth century.

Dyson believes that the energy contained in a planet like Earth is actually very limited, far from enough to support the development of civilization on it to an advanced stage. In a star system, most of the energy comes from the stars, but almost all of it is wasted. At present, the planets of the solar system receive only about 1/10^9 of the solar radiation energy, which is a drop in the bucket.

Dyson believed that a highly developed civilization must have the ability to surround the sun with a huge spherical structure, which would allow most of the sun's radiant energy to be intercepted. Only in this way can the energy consumption of this civilization be supported in the long term and its development to a sufficient height.

Wrapping up a star with a ball, sounds incredible?

It is worth mentioning that Dyson served as Einstein's deputy, and his theory has a certain scientific basis.

According to Dyson's scheme, this advanced technology can produce an almost unlimited supply of fuel. Energy is the primary factor restricting the development of civilization. He envisioned a civilization developed enough to harness the full energy output of their own star by building a sphere or ring of receivers and energy converters.

This structure came to be known as the "Dyson sphere".

Some have taken this idea a step further. They argue that civilizations that are millions of years ahead of Earth may have harnessed the energy of entire galaxies, or even entire clusters of galaxies. These extraterrestrial civilization researchers then divided potential civilizations into three classes.

Level 1 Civilization:

Including the earth, it is the natural resources of the world that have developed to be able to exploit and utilize the world where they inhabit. Strictly speaking, humans should currently be at level 0.7.

Level 2 Civilization:

Able to build a creation on the scale of a Dyson sphere, and able to handle the full energy output of their star. Civilization has advanced to this level and is almost certainly capable of interstellar travel. Such a civilization may have figured out ways to make objects move faster than the speed of light. A culture that has developed to this stage is thousands or even tens of thousands of years more advanced than the earthlings.

Level 3 Civilization:

Millions of years ahead of Earth, and have mastered the use of all the resources of their galaxy. This ability is like belonging to God to the civilization of Earth, but it is within the limits of the laws of physics. Such beings have almost godlike powers.

This classification of civilizations was accepted by most astronomers as soon as it was proposed. Later, it was once used by many science fiction writers.

Since the Dyson sphere absorbs the enormous energy of the star, it is supposed to radiate the same amount of heat as it. This heat can theoretically be detected at scales many light-years away, in the infrared range of the spectrum.

So some scientists have asked, is it possible to use this to discover and look for aliens in deep space?

Li Quan remembers that not long ago, scientists seemed to have made a breakthrough.

Among the more than 100,000 stars observed by NASA's Kepler mission, a team of scientists discovered a unique star called KIC8462852.

The star has a strange and elusive variation in brightness: its light curve is uneven, not periodic. Some peaks are very deep, one up to 15% deep, and another, even up to 22% deep! This is clearly not normal.

According to Kepler's data, KIC8462852 1,500 days, the brightness of the star has dropped by 22%. This alone determines that this cannot be caused by a planetary occlusion. Because even a planet the size of Jupiter can only block about 1% of the star's starlight. Jupiter is already almost the maximum size that a planet can reach.

It can't be another star, because if there were, it should be visible.

In addition, such fluctuations in brightness do not occur regularly and periodically, which is not consistent with the guess of a planetary or stellar transit. So whatever obscures the star must be "huge," at least half as wide as the star itself.

Scientists' initial thought was that could it be some kind of planetary collision event.

Planetary collisions create large clouds of debris and dust that, if they rotate around the star, cause a degree of transit, so it is possible that the phenomena seen so far may be reproduced in the near future. And the problem with this idea is that there is nothing extra in the infrared light of this star. Planetary collisions produce large amounts of dust, which emit infrared light when heated.

Another idea is that there is a series of comets orbiting the star. These comets may be encased in clouds of gas and other matter, and may also produce observed changes in brightness. Because there is another star that is quite close to KIC8462852, and that is a smaller red dwarf, about 130 billion kilometers away. This distance is sufficient to affect its Oort cloud, causing a large number of comets to be disturbed into the vicinity of the KIC8462852, causing this phenomenon.

Comets are a good guess, but it's hard to imagine a scene of a large group of comets that completely obscure 22% of the starlight from a star. 22%, which is a lot of money.

The last thought was that what they saw was an advanced alien civilization that was building a Dyson sphere. Huge solar panels or clusters of solar panels, millions of kilometers wide, with strange shapes, can of course cause changes in the brightness of the star, because the star is partially encased.

Li Quan went back to Earth and searched the Internet in detail about various theories and phenomena about Dyson balls. Finally, it was officially determined that the thing I saw was the Dyson sphere!

One set is set around the star, with a certain gap, and is not a ring-shaped creation that completely envelops the star.

This shows a problem, that is, there is a high civilization in the plane of power travel!

This is a mountain of ironclad evidence, even if he doesn't want to think about it, but it is undeniable that the situation seems to have become complicated.

"I thought it was really some kind of god." Li Quan thought helplessly. He returned to the Game of Throne plane.

Originally, he thought that he would meet some high-ranking beings, such as the Lord of Light, who always expected everything, and sent Melisandre to negotiate with him. If the Lord of Light had been paying attention to him, he would not have been so surprised if he was a god in the true sense of the word in the Game of Thrones.

Now the Lord of Light has not been seen, but the Dyson Sphere has appeared, and there are 6 space stations of considerable scale, whose role is temporarily unknown.

The existence of an extraterrestrial civilization is on the horizon. But the question arises again, since the alien civilization is in this galaxy, why hasn't it appeared? I've traveled back and forth so many times without realizing their existence. Now when I put the satellite into the sky, I shot it down without saying a word. What exactly does the other person think? He didn't believe it was unintentional.

Anyway, he has to talk to the other party. He's not afraid of aliens, he's about to fight aliens, and it's not bad to get in touch with a certain civilization in advance.

At this point, Li Quan felt that he had uncovered the secrets of the world of Westeros.

He still remembers that at the beginning of every episode of the Game of Thrones American drama, Dyson Ball appears. At that time, he always thought that it was just an artistic expression. Now it seems that it would have been too simple to think that way. Ge Wei said that the appearance of the plane is manifested after the spiritual intensity reaches a certain level. God knows what the author of Game of Thrones envisioned in the first place.

At least, he had found the real reason for the unique and strange alternation of seasons in this world.

It's all because of the Dyson ball.

As Westeros orbited the star, the star's Dyson sphere shell was constantly rotating, as was observed in the images sent back by the stealth reconnaissance aircraft.

And when the Dyson sphere shell just covers the star, the heat of the star cannot be transferred, Westeros becomes colder, and the winter becomes unusually long. So there is a legend that winter is coming, and strange ghosts are coming.

The existence of the Dyson sphere will cause the length of the seasons in Westeros to be irregular. In Li Quan's view, this may just be a trivial side effect - for this alien civilization.

He wanted to know the true purpose of this alien civilization here. Do they live on one of the other planets in the system? And most importantly, can you get along amicably? Is there a conflict or a negotiation waiting for him? Li Quan didn't know any of this.

For the time being, we can only let the stealth reconnaissance drone collect more information. The next goal is to get a comprehensive and close look at the Dyson sphere, and then visit every planet in the galaxy to find this advanced alien civilization.
