This time Xiao Yu's target is a red dwarf star, which has a mass of only about a quarter of the sun. The lower surface temperature makes the light it emits appear red, and at the same time gives it an extremely long life. With it
With such a mass, its lifespan will be at least a hundred billion years. But now, it has only spent more than eight billion years of life.
The lifespan of the universe is only over 13 billion years.
From the perspective of life on earth, this time the target planet is just within the habitable circle of the red dwarf star. It is about seven million kilometers away from the main star. This distance means that the temperature on it is not
It will be too high, not too low, and there will likely be liquid water on it. At the same time, it has an atmosphere and its own magnetic field. The atmosphere and magnetic field mean that it can more effectively resist alien asteroids and various rays.
attack, better protect the life on its surface, if there is life on it.
This is a planet full of hope. It can be said that among the more than 500 star systems that have been explored, this planet has the best conditions.
At this moment, Xiao Yu is about 1.7 light-years away from this star system. At Xiao Yu's current speed, it only takes two and a half months to reach it.
The closer to the star, the more detailed information will be observed by Xiao Yu. Therefore, in the process of constant approach, Xiao Yu will encounter surprises every time.
"It...it actually has a satellite? The significance of this satellite is too great, which means that its homeland security has an additional layer of guarantee. At the same time, if it has liquid water, the satellite will make these liquids
Water forms tidal waves... Also, the gravity of the satellite has a very good effect on the geological activities of the planet. This satellite at least increases the possibility of living things on it by five percentage points."
"Well? This star has an Oort cloud? These many comets... contain enough water. This means that in the early stages of the formation of this planet, many icy comets have impacted it, and there is a lot of water on it.
There may be liquid water present."
One piece of good news after another made Xiao Yu's sense of expectation reach its peak again and again. During the meticulous observation activities, two and a half months passed by, and Xiao Yu had arrived only seven days away from the red dwarf star.
A billion kilometers away, a sublight-speed voyage was launched.
Under the tachyon detection instrument, Xiao Yu discovered that the moment he broke away from the super-light voyage, the fourth-level alien beast also broke away from the curvature sailing state and was still behind him, following him.
"This lingering guy." Xiao Yu cursed secretly in his heart. After leaving the super-light voyage, the ordinary super-light broadcast communication method could be used, so Xiao Yu simply sent a message: "You are this
Guy, you have been chasing me for almost 700 light years. Are you tired?"
Xiao Yu's response was a message full of cold meaning: "Whether it's seven hundred light years, seven thousand, or even seventy thousand light years, you and I will fight until we die."
"Unreasonable guy." Xiao Yu scolded. "Stop hiding, you can't escape my detection. Are you fighting to the death with me? You are still a little bit behind. I am always preparing for a fight, so I will
I don’t believe you can take advantage of me."
Judging from the current situation, as long as Xiao Yu is careful and is not attacked, this fourth-level alien beast will indeed not be able to take advantage of Xiao Yu.
"One day I will find an opportunity to kill you." This level four alien beast said coldly.
Xiao Yu simply ignored it and followed it as long as it wanted, as if it had an extra tail that was a bit in the way, Xiao Yu thought.
The sublight speed is 170,000 kilometers per second. At this speed, a distance of 7 billion kilometers can be covered in less than thirty hours. Taking into account the acceleration and deceleration time, Xiao Yu will
Reach the target within two days.
Because the light of this star is so dim, even if it is only 7 billion kilometers away, it is still very dim and does not show any different characteristics from other stars. And if it were replaced by the sun, the sun would still be above this distance.
Has the brightness of a full moon.
The difference between the two is obvious.
But this is changing rapidly. As the distance approaches, the brightness of this star is rapidly increasing. From the earth, the brightness of Venus increases to the brightness of the moon, and then continues to gradually increase... until it is brighter than the sun.
Until it gets a little darker.
Here, seven million kilometers away from it, here is the orbit of that planet.
At this moment, Xiao Yu was staying 40,000 kilometers above the planet, admiring the planet like a fine work of art from a distance.
Above Xiao Yu is a round moon that emits soft light, and below is a planet with a light red color. Surrounded by the light red color, there are some other colors, such as pink, such as
blue.
Xiao Yu knows that those light red things are liquid water. The blue color of the ocean above the earth is determined by the spectrum of the sun, and the spectrum of this red dwarf star is different from that of the sun. Naturally, the ocean on the planet
The color of the ocean is also different.
In addition, Xiao Yu also knows that those pink things should be plants on this planet. Yes, the plants on it are not green but pink. This is also determined by the spectrum of this star.
.Because the pink color can absorb the energy of this star to the maximum extent. Therefore, according to the theory of evolution, they will inevitably evolve this color.
As for the other colors, I don’t know what they are. They may be clouds in the atmosphere, or they may be other things. This requires further detection to know.
At this moment, Xiao Yu felt excited and disappointed at the same time. He was excited because he had finally discovered a living planet, but he was disappointed because Xiao Yu knew that although there were living things on this planet, the possibility of intelligent life beings was not high.
.In other words, it is unlikely that there will be intelligent creatures whose technology has developed to a certain extent.
Because Xiao Yu has not found any man-made objects in the low-Earth orbit of this planet. The creation of satellites orbiting the planet is a sign of primary and secondary civilizations, which means that the vision of a civilization truly extends from the surface of the planet to the universe.
in space.
"No, there would be nothing." Xiao Yu sighed, "As long as there are intelligent creatures, even if they are just creatures in primitive society. Leave such creatures to me, and through genetic modification and species optimization, within three hundred years, we can
Within a thousand years, I can improve them to a level no less intelligent than human beings. Within a thousand years, I can probably contribute to the development of my science and technology."
From Xiao Yu's current perspective, human-level wisdom is no longer highly valued by Xiao Yu. This is because the development of science and technology will in turn improve the quality of intelligent and civilized creatures themselves. For example, genetic technology can eliminate the problems of various diseases and greatly improve the quality of intelligent civilization.
Improving the lifespan of intelligent civilization creatures, species optimization can increase the brain capacity of intelligent civilization creatures, allowing them to have faster reaction speed, calculation speed, thinking speed, etc.
Therefore, the higher the level of civilization, the smarter its intelligent civilization creatures will be. This sentence is basically correct.
With a trace of expectation and a trace of apprehension, Xiao Yu sent out a formation of rural-level spaceships and gradually approached the planet.
After passing through the atmosphere, the first thing that caught Xiao Yu's eyes was an endless expanse of light red ocean. Through the detection of instruments, Xiao Yu knew that the air at this moment was very humid, the temperature was very suitable, and the oxygen content was no lower than on the earth.
, if you still have a body, you will definitely feel very comfortable if you expose your body to such an environment.
Blown by the breeze, the surface of the red ocean was rippled with light. In the sky, a red sun hung there, and everything seemed quiet and peaceful.
But Xiao Yu didn't find what he wanted. On the ocean here, Xiao Yu didn't even see a canoe.
You know, canoes are a technology that primitive humans have mastered.
"Maybe it's because it's too far from the land." Xiao Yu murmured to himself. Up to now, Xiao Yu still refused to give up his hope. Under Xiao Yu's control, three hundred of the village-level spacecraft formation
The remaining spaceships dispersed and flew towards different places.
A spaceship came to the mountain peak. Under the light of the red dwarf star, the accumulated snowflakes also showed a light red color. They looked very beautiful. A spaceship came to the forest and looked at
With these pink plants of different heights, Xiao Yu began to feel comfortable. A spaceship came to the grassland. On top of these pink plants, Xiao Yu discovered what he had come to this planet.
The first animal I saw.
This is undoubtedly a herbivorous animal. The theory of evolution has given them flat teeth suitable for grinding plants and photosensitive organs in the front. These things allow them to survive on this grassland relatively comfortably. But it
At the same time, there is no doubt that they are not intelligent creatures.
Whether tools can be used is the most important indicator to distinguish intelligent creatures from ordinary creatures. On this animal, Xiao Yu did not find any limbs that could be used to use tools.
Its appearance is somewhat similar to the antelopes on the earth, except that they are obviously stronger. Xiao Yu knows that this is because of the gravity of this planet. The gravity of this planet is greater than that of the earth. In order to resist
With stronger gravity, their bodies must also become stronger.
Next to it, another animal was quietly approaching here. This herbivorous animal did not notice the coming crisis, and it was still eating quietly there. Then, the obviously carnivorous animal suddenly jumped up and pulled it
