"Attention everyone! Start slowing down!"

When they set foot on the interstellar voyage again, they headed to the destination star. After receiving the feedback signal from the destination star, they opened the air-tight valve in their body and sprayed hydrogen clusters on the antimatter shield in front to cause annihilation reaction and release. A lot of gamma rays are used to slow down.

　　 Time and space changed from distortion to normal, and the star rainbow phenomenon disappeared, and the stars returned to their correct positions.

　　 After reaching the outermost Kuiper belt of the destination star, some individual collectors eagerly turned on their bio-radar to observe the star system that was about to be occupied by them.

　　 "A single star system, the main sequence star is a yellow dwarf, but the mass is small, the number of inner planets is five, in addition to the Kuiper belt, there are also two asteroid belts orbiting the star."

　　 "Confirmation completed, same as remote observation."

　　 The individual observing collector broadcasts the information he has observed to all members. Not only does it act like this, there are also several collectors in the group.

　　 This is to avoid observation errors. The longer the distance, the greater the observation error. Increasing the number of observers is an excellent way to reduce the error.

　　 So far, the distance is calculated from the star system of the designed pressure giant as the starting point. At present, the collectors have crossed a total of more than 60 light-years.

　　 "Alas, it's an ordinary star system. Why can't it be discovered? Just like the habitable planet with a complex ecosystem that was discovered before."

　　 Some gatherers complained in the group, because the excitement of the habitable planet in front of them inspired some gatherers to look for other civilized races.

Finding a new civilization will be of great help to the ethnic group, and the ethnic group will usher in a new change-all collectors agree this way, even if it is a newly born individual, because the Celine civilization is to let the whole The ethnic group has made progress beyond imagination, so they think so.

Without the Céline civilization, it would be difficult for them to study mathematics and physics in depth, and at most they can only reach the shallow level. The limit for the development and growth of the ethnic group stops at the two fields of chemistry and organic biology. It is impossible for ethnic groups to study mother Ship creatures, antimatter megastructures, leapfrog creatures, proton crystal lattices... These, although they have the ability to do so, but unexpectedly, such a concept would not have existed from the beginning.

　　 Therefore, the discovery of a new civilization means the discovery of a new field of knowledge, which has become a subconscious idea of ​​the collectors. Of course, the new field of knowledge also means a new round of technological explosion of the ethnic group.

　　 This is a great thing, and of course the collectors are very eager.

　　 "The requirements should not be too high. That kind of planet is very rare. If it is everywhere, then we don't need to keep that planet specifically for ethnic research."

"That's how it is said, but even if we lower the standards, we have never encountered a planet with life. I originally thought that even if we couldn't find a livable planet in a complex ecosystem for a while, we would find some algae, fungi, and single species. Cell biology should still be very simple."

In a voyage of more than 60 light years, the collectors have experienced two star systems, one is a three-star system, and the other is a four-star system. They are all stable, and the distance between each other is more than 20 light years, except for one of the four star systems. Apart from the novel observation experience provided by the star system to collectors, the others are similar.

　　 is nothing more than planets, stars, asteroids, and interstellar dust.

　　 "If life were everywhere, the universe would not be as dead as it is now."

　　 "Huh? Dead silence..."

　　 said Wuxin, listened intentionally, and the reply from the same family made the individual who was still complaining ponder.

"what's happenin?"

　　 Seeing that there has not been a reply for a long time, the comrades who were communicating with this collector gave back information, and the collectors also asked their ancestors to ask for confirmation.

　　 "You just said that the universe is dead, right?"

　　 "That's right, if it is not dead, we can easily discover new civilizations. As long as these civilizations are technically capable of being out of the planet's gravity, it is not difficult to achieve communication on the scale of a few light-years."

　　 thought that the collector was thinking about the reason that the universe environment was judged as ‘dead silence’ in his previous words, and he was in distress, explaining his reason for saying so.

The collectors are very puzzled, because the standards given by the same family are too low. It is not that simple to carry out light-year-scale communication. Take the feedback information required for sub-light speed navigation, it takes a whole satellite. Only planetary energy supply can realize the feedback signal that spans several light years.

　　 The feedback signal of the present type is transferred from the planet to the orbit of the star, and the energy is supplied by the star, so that the feedback signal can span more than 20 light years without attenuation.

　　 The technical difficulty here is of course needless to say, but it’s not a simple thing as “just need to be able to escape the gravity of the planet” as the family said.

　　 "How to achieve it? It is enough to get rid of the planet's gravity? There are no other additional conditions?"

　　The collector finds it unbelievable ~lightnovelpub.net~ Although it knows that there is no reason for its clan to talk nonsense to it, it can't imagine what it should do to exchange information with a level of technology that is out of the planet's gravity and sight across light years.

　　 Hearing the inquiries from the collectors, the same clan told the collectors of their thoughts without hesitation.

"Yes, just this is enough. It is very simple and direct to use the visible spectrum of stars to communicate. Apart from the shortcoming of the speed of light delay, there are basically no shortcomings. Even the observer is saved, and the naked eye of the Celin is used. You can get information that spans light years."

　　 Transmitting Morse code through the brightness change of stars can also achieve ultra-light-year ultra-long-distance communication. This kind of technical difficulty is not high, and the difficulty lies in how to shield the stellar light so that the stellar brightness changes significantly.

　　 But the collector thought about it carefully, and felt something was wrong, so it immediately refuted the same clan.

　　 "No, I know the use of stellar spectrum communication. It requires enough orbiting satellites to obscure the stellar illumination, and at least one entire planet needs to be dismantled."

The reason why the collectors say this is because they did it. The original star broadcasted the information by relying on this method, combining the polarized spacecraft of the Serines and the polarized organisms later added by the Hogu. So as to realize Dyson Cloud is construction.

　　 Relying on this Dyson cloud, changing the brightness of the stars, it also realizes light-year-level broadcast communications.

　　 However, this idea of ​​the collector was quickly rejected by the same clan.

　　 "No, no, no, it doesn't need to be that level."
