Four months later, the Vanguard spacecraft had actually entered the edge of the Red Dark Nebula, and from this distance they had officially arrived at the Red Dark Nebula, and as they moved further into the nebula, the surrounding environment became more and more complex and the navigation became more difficult.

Fortunately, the central brain system of the Pioneer spacecraft has been upgraded, if you look at the situation before the upgrade, in this case, the Pioneer spacecraft can no longer continue to sail in the curvature flight state, and now the upgraded Pioneer spacecraft can still continue to fly in the curvature state to the inside of the red dark nebula, but its speed cannot reach the highest curvature, but in any case, the current sailing speed is much stronger than the normal flight state.

After starting to really enter the Red Dark Nebula, Su Yichen and the others were surprised to find that the Red Dark Nebula was a little different from what they had expected. According to the initial data, the core of the red-dark nebula is almost 25 times the size of the solar system, and the entire nebula is an irregular cluster of nebulae that appears a dark red color in the universe. And the factors that produced it were formed by the final death process of the dying small galaxy, and the death process of this galaxy continues to continue, so that this bizarre nebula state is produced. What's even more strange is that in this nebula, there seems to be a new small galaxy in the process of forming at the same time as the stars die. Life and death are at the same time, and this situation is extremely rare even in the universe.

Inside the nebula, a huge amount of material is flooded, and coupled with the two completely different states of ejection and inward extrusion, the interior of the nebula exists in an extremely unstable posture. Even within this red-dark nebula, there may be previously dead stars and whole moving stars, and it is more likely that there are black holes forming.

And now when they reached the outer periphery of the Red and Dark Nebula at close range, and advanced towards the interior of the nebula along the edges, they realized that the initial information was quite different from what they saw in front of them. The first is the size of the red dark nebula. Originally thought to be about 25 times the size of the entire solar system, according to the solar system from the Sun to the Oort Nebula, the radius is 0.5 light-years, which means that the diameter of the entire solar system is about 1 light-year. Multiply this by 25, and the diameter of the red dark nebula is 25 light years. But as things stand, the diameter of the red-dark nebula is much larger than that. The most conservative estimate is that the entire red-dark nebula is nearly 100 light-years in diameter, and if the outer regions of the red-dark nebula are also included, then its diameter is about 150 to 160 light-years or more.

Secondly, the entire nebula is in an extremely unstable posture from a physical point of view, because the continuous evolution of the massive amount of material in the nebula, coupled with the two extreme changes caused by the collapse of dead stars and the formation of new stars, makes the red dark nebula almost equal to the forbidden zone of life.

And on the way here, Su Yichen and they have always thought so, but now reality has overturned their opinion. Although in the marginal region of the red-dark nebula. Including the interior of the direction of travel, the complexity of the terrain is unprecedented in the whole universe, and from a local point of view, the entire nebula is not as dangerous as imagined, and there are still balance and safety points in many areas. This imagination couldn't help but make Su Yichen think of a similar astronomical phenomenon, that is, the phenomenon of the eye of the wind.

Storms, which are very common climatic phenomena on Earth, especially in the oceans and coastal zones. The formation of typhoons can happen anytime and anywhere. But hundreds of years ago, scientists discovered a very strange situation, and that is a storm, no matter how violent. However, the most dangerous areas are often in the outer and remote areas of the storm, while the calmest areas are closer to the center of the storm, which is known as the eye of the storm.

Now, the red-dark nebula also seems to reflect this unique phenomenon, but this eye of the wind phenomenon is not a global phenomenon but a local phenomenon, which creates instability in some areas. In other regions, the situation is relatively stable. At first, Su Yichen thought it was a local unique phenomenon, but as he went inside, the more this situation appeared, which made him a little overjoyed. After all, in such a long-distance environment, the more complex the distance, the more dangerous it is. And now it is possible to ensure the safety of at least part of the journey, and in this case the speed of the Pioneer spacecraft can be accelerated in some areas, which also shortens their time.

"It's really beautiful, I didn't expect that from this angle, the red dark nebula looks like a beautiful gem." Standing on the bridge, Luo Yan looked at the red and dark nebula that was close at hand, and looked at it, in the dark universe, the red and dark nebula was as beautiful as a huge gem.

The whole nebula forms a clump, which is irregular, the upper part is somewhat narrow, and it begins to collide in the middle, and gradually shrinks to the lower part, resembling an ellipsoid. The interior of the nebula is red and black, and the two colors are different in light and dark. The light red is a little yellowish, the crimson is as thick as chicken blood, and even the black has several colors, dark black and blue-black, especially the excessive and strong contrast between the intersection of colors and colors, showing a brilliant and colorful color in the universe.

Luo Yan is right, it is like a beautiful gem, and it is a brilliant and brilliant gem set in the depths of the universe. Compared to the massive red-dark nebula, their Vanguard spacecraft was like an insignificant speck of dust, heading down its course.

Su Yichen and Luo Yan are both experienced astronauts, and they have even experienced space travel across extragalactic galaxies, but now, they are still shocked by this incomparably beautiful scene, which can be said to be the most brilliant and attractive starry sky they have ever seen in their lives.

"It's so beautiful, and the creation of nature is incomparable to any man-made being." Standing beside Luo Yan, Su Yichen couldn't help but admire, looking from the bridge, they were like in a dreamy color, this shocking beauty could not be described in words.

Just when they were immersed in this scenery and sighed, the brain system suddenly issued an alarm, Su Yichen and Luo Yan hurried back to the console, at first they just thought that the alarm of the brain system was the same as before to remind the route adjustment, but when they saw the alarm content clearly, they were stunned at the same time.

"Impossible!" Luo Yan blurted out in surprise, her eyes full of incredulity. In fact, not only her, but even Su Yichen suspected that the content of the alarm was wrong. Hurriedly issued an order to the brain system to review.

After a few minutes, the review content appeared, and the consistency of the two contents confirmed the authenticity of the alert. Faced with this result, Su Yichen and Luo Yan looked at each other and were speechless for a while.

"Is it a relic of civilization?" Luo Yan hesitated to guess, and Su Yichen shook his head. He is not denying it, but not being sure. The reason for their confusion was, of course, the content of the alert, because the brain system told them that a terrestrial planet had been discovered about ten light-years away in the direction of their path.

In the entire outer zone of the red and dark nebula, there are not a few terrestrial planets, and there are countless terrestrial planets that they have passed through and recorded along the way. However, this time it was different, the reason why the brain system issued a warning was because it showed that this terrestrial planet had signs of a living planet, which surprised Su Yichen and his wife.

The Red Dark Nebula has always been considered a forbidden place for life in the cosmic civilization of the Milky Way, and from the formation of the Red Dark Nebula and its structure. It seems that there is no normal cosmic civilization that can survive here, but now that they have discovered a terrestrial planet that may have a civilization, this almost impossible thing makes them stunned for a moment.

Luo Yan put forward the speculation of the relics of civilization, which is theoretically feasible. Her speculation was based on the formation of the red-dark nebula, or the destruction of the stars inside the red-dark nebula, during which time the airspace formed a small galaxy with living planets, and thus the possibility of civilization. But you know. Hundreds of millions of years have passed since the formation of the Red Dark Nebula to its current scale. In such a long period of time, even if there are the existence of previous civilizations and the remnants of relics, they have long disappeared into the river of time with the passage of time.

So, what is the real answer, is there really a unique civilization there? And how did this civilization survive? Why is it hidden in the Red Dark Nebula unknown to other civilizations? These questions flashed through the minds of the two, and eventually they looked at each other silently. Decided to check it out.

The course was not adjusted too much, and Su Yichen only gave the Zhi Brain System an order to temporarily detach from the curvature voyage after approaching that kind of earth planet. To be on the safe side, they plan to sail away from the current curvature at a distance of 0.2 light-years from the terrestrial planet, and then scan and search again to find out what is going on on the planet, which may have signs of life.

When the Pioneer spacecraft once again passed through the preset course. When approaching the vicinity of this terrestrial planet, it broke away from the curvature state, at this time, Su Yichen and Luo Yan were very surprised to find that there was a relatively balanced airspace here, and this airspace also resembled a small galaxy, but a small star here was much smaller than the sun in the solar system in terms of volume and mass, and there were very few terrestrial planets revolving around it, only three, these three terrestrial planets were two large and one small, and the terrestrial planet that the brain found was the smallest of them.

Along the way, they encountered a lot of relatively stable areas, but it was the first time that they encountered such a balanced and safe area with this place. This small galaxy is small, only one-fifth the size of the solar system, and on its periphery is a circle of enveloping areas formed by various celestial bodies, which, when viewed from a distance, looks like an egg protected by a shell, and the star much smaller than the sun is its yolk, and it is precisely because of its gravitational attraction and action that the operation of the huge red-dark nebula creates a delicate balance between each other.

As for the terrestrial planet, it was slightly smaller than Earth, and its color in space was a little yellow to blue, which reminded them of the primordial planet found in the Andromeda galaxy at a glance. Detached from the curvature voyage, the Vanguard spacecraft began to scan the terrestrial planet, in fact, when they saw the planet, they already sensed that there might be life on it.

In the entire universe, all living planets have a unique characteristic, which is their color structure. Planets that have life, whether primitive or cosmic civilizations, have blue or green in their colors, but the structure is different, and these colors are different. It's like Earth, or Blue Star, and other cosmic civilizations, even the Andromeda Galaxy's Galen planet and the primordial planet. And the appearance of this planet now basically confirms that it has a great possibility of life.

When Su Yichen and Luo Yan saw this, they had both expectation and apprehension in their hearts, maybe they had discovered a civilization that was isolated from the galactic cosmic civilization, or an unknown cosmic civilization, but no matter which one it was, this was an extremely important discovery.

When the Central Brain began to search for the terrestrial planet, they all waited intently for the search screen to appear. Soon, it didn't take long for a three-dimensional star map to unfold in front of them, as the star map got closer, they could gradually see the appearance of the planet clearly, the first thing they put into their eyes was the near-Earth space region of the terrestrial planet, where did they not find equipment similar to aircraft and satellites, as for what space cities and spaceships did not, this result made Su Yichen's heart feel a little more at ease, at least he could judge that even if this planet has a civilization, it is a very low civilization, Its level of civilization is not even as good as that of the late primitive civilization before the earth entered the cosmic civilization period.

This situation can ensure that the planet will not bring any danger to them regardless of whether there is civilization or not, and then after confirming it again, the central brain system began to scan the surface of the planet, and when these pictures became clearer and clearer as the scan became clearer, gradually showing in front of them, first skimming the ocean, then the mountains, then the forest and the earth, there were many signs of artificial structures faintly appearing in the picture, which means that there is indeed a civilization on the planet, and when the picture continues to zoom closer, cities begin to appear, And when one of the cities was locked and enlarged, Su Yichen and Luo Yan suddenly saw a building, and the two of them were startled at the same time, and couldn't help but raise their hands and rub their eyes, they couldn't believe what they saw, and then they were immediately stunned.
