This time, Xiao Yu's target is a red dwarf star, and its mass is only about a quarter of that of the sun. The low surface temperature gives it a red glow and gives it an extremely long lifespan. With its quality, it will have a lifespan of at least 100 billion years. And now, it has only passed more than 8 billion years of life.

The lifespan of the universe is only about 13 billion years.

From the perspective of life on Earth, the target planet this time is within the habitable circle of this red dwarf, which is about 7 million kilometers away from the main star. This distance means that the temperature above it is not too high, nor too low, and there is likely to be liquid water on it. At the same time, it has an atmosphere and also has its own magnetic field. The atmosphere and magnetic field mean that it is more effective against alien asteroids and rays, and can protect itself from life on the 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, there is one planet, which is the most conditional.

At this moment, Xiao Yu is about one point and seven light-years away from this star system, and at Xiao Yu's current speed, it only takes two and a half months to reach it.

The closer you get to this star, the more detailed information will be observed by Xiao Yu. So, in the process of continuous approaching, Xiao Yu will encounter surprises at all times.

"It'...... It even has a satellite? The significance of this satellite is too significant, which means that it has another layer of security for its homeland, and at the same time, if it has liquid water, the satellite will make the liquid water tidal...... Also, the gravitational pull of the satellite. It also has a very good effect on the geological activity of the planets. This satellite, at least five percent more likely to have creatures on it. ”

"Huh? Does this star have Oort clouds? These many comets...... The water content is very sufficient. This means that in the early days of the planet's formation, there were many ice comets that hit it, and it is likely that there was liquid water on it. ”

One good news after another made Xiao Yu's sense of expectation rush to the peak again and again. In the meticulous observation activities, two and a half months have passed in a flash, and Xiao Yu has come to a place only seven billion kilometers away from this red dwarf star, and has embarked on a sub-light speed voyage.

Under the tachyon detection instrument. Xiao Yu found that the next moment he broke away from the faster-than-light voyage, the fourth-level alien beast also broke away from the curvature navigation state, and was still behind him, following him.

"The haunted one." Xiao Yu secretly cursed in his heart. After breaking away from faster-than-light travel. The ordinary means of faster-than-light broadcasting communication can already be used, so Xiao Yu simply sent a message over: "You guy." It's been chasing me for almost seven hundred light years. Are you tired? ”

In response to Xiao Yu, there was a message full of coldness: "Seven hundred light years, seven thousand, or even seventy thousand light years, you and I will never die." ”

"Unreasonable fellow." Xiao Yu scolded. "Don't hide, you can't hide from me. And I'm not going to die? You're a little bit close. I'm always ready to fight, and I don't believe you can take advantage of me. ”

Judging from the current situation, as long as Xiao Yu is careful. Without being raided, this fourth-level beast really couldn't take advantage of Xiao Yu.

"Someday I'll find an opportunity to kill you." The fourth-level beast said coldly.

Xiao Yu simply ignored it, and followed it if he loved it, just as he had an extra tail that was a little in the way, Xiao Yu thought.

The sub-light speed is 170,000 kilometers per second, and at this speed, it takes less than 30 hours to cross a distance of 7 billion kilometers. Counting the time to accelerate and decelerate, Xiao Yu will reach the target in two days.

Because the star's light is so faint, even at a distance of only seven billion kilometers, it is still very dim and does not show any characteristics that distinguish it from the rest of the stars. And if it is replaced by the sun, the sun will still have the brightness of a full moon above this distance.

The difference between the two can be seen.

But that's changing fast. As the distance approached, the star's brightness increased rapidly, from the brightness of Venus from Earth to the brightness of the Moon, and then continued to gradually increase...... until it is a little dimmer than the sun.

Here, seven million kilometers away from it, here, that's the planet's orbit.

At this moment, Xiao Yu is staying 40,000 kilometers above this planet, admiring this planet like a beautiful work of art from afar.

Above Xiao Yu is a round moon that releases a soft light, and below, there is a planet with a pale red hue as a whole. Surrounded by pale reds, there are other colors such as pink and blue.

Xiao Yu knew that those pale red things were 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 not the same as that of the Sun.

In addition, Xiao Yu also knew that those pink things should be plants on this planet. That's right, the plants on it are not green but pink. Again, this is due to the star's spectrum. Because of the pink color, it can receive the energy of this star to the maximum. So according to evolutionary theory, they must have evolved this color.

As for the rest of the colors, I don't know what they are, maybe it's clouds in the atmosphere, or maybe it's something else. This will require further probing.

At this moment, Xiao Yu's mood was both excited and disappointed. I was excited because I had finally discovered a planet of life, and I was disappointed because Xiao Yu knew that although there were creatures on this planet, it was unlikely that there would be intelligent creatures. In other words, it is unlikely that there will be intelligent beings that have developed to a certain extent in science and technology.

Because Xiao Yu did not find any man-made objects in the low earth orbit of this planet. The creation of satellites orbiting the planets 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.

"If you don't, you don't." Xiao Yu sighed, "As long as there are intelligent creatures, even if they are just creatures in a primitive society. Leave it to me that through genetic modification and species optimization, I will be able to elevate them to a level that is not inferior to human intelligence in three hundred years. Within a thousand years, I will probably be able to contribute to the development of my science and technology. ”

With Xiao Yu's current vision, the wisdom of the human level is no longer much valued by Xiao Yu. Because the development of science and technology will in turn improve the quality of intelligent civilization organisms, for example, gene technology can remove the trouble of various diseases, greatly improve the life span of intelligent civilization creatures, and species optimization can improve the brain capacity of intelligent civilization creatures, so that they have faster reaction speed, calculation speed, thinking speed, etc.

Therefore, the higher the level of civilization, the more intelligent civilization creatures will be, and this sentence is basically not wrong.

With a hint of anticipation and a hint of apprehension, Xiao Yu sent a village-level spaceship formation to gradually get closer to the planet.

After passing through the atmosphere, the first thing that caught Xiao Yu's eyes was a large boundless sea of pale red. Through the detection of the instrument, Xiao Yu knew that the air at the moment was very humid, the temperature was very suitable, and the oxygen content was not lower than that on the earth.

Under the breeze, the surface of the red ocean is sparkling, and in the sky, a red sun hangs there, and everything seems quiet and peaceful.

But Xiao Yu didn't find what he was looking for. Above the ocean here, Xiao Yu didn't even see a canoe.

You know, the canoe is a jishu that primitive humans have mastered.

"Maybe it's because it's too far from land." Xiao Yu muttered to himself. Until now, Xiao Yu still refuses to give up his hope. Under Xiao Yu's control, the more than 300 spaceships in the village-level spaceship formation scattered and flew towards different places.

A spaceship came to the top of the mountain, under the light of this red dwarf star, these piled up snowflakes also showed a pale red color, which looked very beautiful, a spaceship came to the forest, looking at these pink plants of different heights, Xiao Yu's mood began to become comfortable, a spaceship came to the grassland, on these same pink plants, Xiao Yu found the first animal he saw when he came to this planet.

This is undoubtedly a herbivorous animal. Evolution has endowed them with flat, grinding plant teeth and photoreceptors that grow in front of them, which allow them to survive comfortably on this grassland. But at the same time, it is undoubtedly not an intelligent being.

The availability of tools is the most important indicator of distinguishing intelligent beings from ordinary organisms. In this animal, Xiao Yu did not find any limbs that could be used to use tools.

Its appearance is somewhat similar to that of the antelope on Earth, except that they are significantly more robust. Xiao Yu knew that this was because of the gravitational pull of the planet. The planet's gravitational pull is greater than that of Earth, and in order to resist a stronger gravitational pull, they must also be physically stronger.

Nearby, another animal was quietly approaching. The herbivorous animal did not recognize the impending crisis, and it continued to eat quietly there. Then, the apparently carnivorous animal jumped to its feet and threw it underneath...... (To be continued......)
