Chapter 2906: Dyson Ball

This time, the mysterious disappearance of the unknown light spot was very close.
Moreover, the sea of ​​clouds also clearly captured that the disappearance of this mysterious light spot was not an instant disappearance.
Its luminosity gradually dimmed first, then disappeared completely.
Without a trace of hesitation, the almost absolute invisibility obtained from the "Hidden Beast Alien" was displayed, and Yunhai quietly approached that area.
Before he was completely close to that area, a technological instrument appeared in his mental senses.
Its shape is round, and the diameter of the black metal instrument is about three meters.
On its surface, a large number of mechanical arms protruded.
At the top of each robotic arm, there is a radar-like device.
Almost instantly, Yun Hai determined what it was.
There is no doubt that it is a "detector" of a certain technological civilization.
When passing by the ghostly "detector" wandering in the icy universe, the sea of ​​clouds suddenly stopped.
Along with the fluctuations in the void, he was generally not sure whether it was a transport ship or a battleship spaceship that appeared not far from the "detector".
The shuttle-shaped spacecraft is black, just like the appearance of that "detector", on its surface a large number of robotic arms extend larger and more "radars".
It didn't stop, obviously it was just passing by.
After the space transition appeared, the black spacecraft advanced a certain distance at a constant speed, and then another space transition disappeared.
This time, Yunhai discovered more.
At the bow of this black spacecraft, there is a luminous "rainbow" pattern.
He wasn't sure what this pattern represented was the name of the spacecraft, or the so-called civilization symbol of the spacecraft.
It only took a few seconds to rummaged through the sea of ​​memories and immediately determined that among all the civilizations he had experienced before, no "technical civilization" had such a graphic logo.
It was only the appearance of the spacecraft, Yunhai stayed for a while, and no other spacecraft passed by.
No longer wasting time, he did not chase the spaceship, but flew towards the star field where the light spot disappeared.
It didn't take much time, Yun Hai quickly rushed to the target area.
That is a star system, a star system without stars.
That's right, when approaching this star system, the mental senses of the sea of ​​clouds have enveloped it.
From the icy ring-shaped meteorite on the edge of the star system to its center, there are more than 300 large and small celestial bodies, and the number of planets has reached 26.
However, there is no star in its center.
There are no stars, but there is a special thing.
Among the spiritual senses of the sea of ​​clouds, the core position of the planet, where the star originally existed, was replaced by an unusually huge and strange thing.
Around it, there are dozens of large and small "space bases" and more spaceships in different locations.
Say it is weird, there is a reason.
At least so far, Yunhai has not seen metal artifacts much larger than planets.
Its appearance is some black metal, which is impossible for Yunhai to make a mistake.
But it is too big. At least no planet in this star system can have its size, which is absolutely comparable to the size of stars.
Although this scene is strange, Yun Hai probably guessed something.
A large number of planets in the universe are energy sources for more civilizations, including fiery stars.
In fact, there is more energy contained in stars.
Basically speaking, just converting its light and heat radiation into energy is enough for a civilization to use for a long time.
For example, the "Dyson Sphere" proposed by "Earth Human Civilization" creates a huge structure within a certain radius around the star to "wrap" the star, and the inner surface can continuously absorb the radiant energy of the star and fully utilize the energy of the star.
Yunhai believes that it is more than 99% possible that what he sees now is a "Dyson ball", which also explains the inexplicable disappearance of the light spot he observed earlier.
After confirming this, the vigilance in his heart faded.
To be able to completely absorb the energy radiation of stars through the "Dyson sphere" method, for the former "human civilization on earth", this "technical civilization" must be an advanced civilization.
But for the current Yunhai, this "scientific and technological civilization" is at best an "intermediate technological civilization."
More "technical civilizations", such as "smart micro-civilization", "Morning Star Federation", etc., have already passed this stage.
Compared to the construction of the "Dyson Sphere", which completely utilizes the energy radiation of the stars, and also consumes terrifying materials to build the "Dyson Sphere" itself, they already have a better and easier way to obtain more energy.
It is estimated that the other party is only an "intermediate technological civilization", and Yunhai did not hesitate anymore. He chose an edge position without spacecraft coming and going, and then flew towards the inside of the star system.
What he wants to do is to figure out what kind of civilization they are as much as possible.
If possible, Yunhai also wants to contact them to see if they can find the clues they want.
However, just as he approached the central region of the star system, something unexpected happened to him.
The "space base" and the spacecraft close to the "Dyson Ball" suddenly began to evacuate, dragging a long light red tail flame, and they quickly retreated toward the outer star system.
The speed of the spacecraft was very fast, and it only took ten seconds to complete the retreat.
In the huge star system, apart from dozens of detectors not far from the "Dyson Sphere" in the mental senses of the sea of ​​clouds, the rest are the celestial bodies of the star system itself.
I was a little strange in my heart. The unknown sea of ​​clouds did not think that they were already strong and powerful, so they chose to stay in the star system, but they also silently retreated to the "interstellar medium region" outside the star system.
At this time, his mental senses caught a special electric wave signal.
The source of the radio wave signal is retreating to a space base outside the star system, and the front direction of the radio wave signal transmission is precisely the "Dyson sphere" in the star system.
Just a few seconds after the transmission of this radio wave signal, I was shocked by the sea of ​​clouds that I thought I wouldn't encounter in this "technological civilization".
The huge "Dyson Ball" suddenly began to shrink.
Yunhai was sure that he had not made a mistake, the metal "Dyson Ball" shrouded in a huge star suddenly began to shrink.
In that case, it was like the metal "Dyson Ball" turned into a leaking balloon.
At first, it was very slow.
But after the volume of the entire "Dyson Ball" was reduced by one-tenth, its speed suddenly accelerated.
