Super Battleship Reborn

The so-called heliosphere is a big bubble blown out by the sun in the cosmic space, and the heliopause is the edge of the bubble. The several large planets that human beings have proven are all within the range of the heliosphere. The sun generously shelters her people, and uses its own radiation activities to open up a region exclusively for itself in the vast cosmic space. In the past, this was a safe haven for humans. If there is no heliosphere, all kinds of terrifying rays and energy bursts in the universe will make nothing grow on the earth, and no life can survive.

Now, this is also Xiao Yu's safe haven. After stepping into the heliosphere, Xiao Yu withdrew from the curvature navigation and started to move forward in a conventional way. Here, Xiao Yu once again saw the traces he left a hundred thousand years ago.

The tomb of seven billion humans, Xiao Yuli.

The tombstone is still revolving quietly around the sun on its own orbit. Low-power candles that use nuclear energy as an energy source are still radiating faint light, illuminating this line of writing. Its design life is not so long, but just like the Curiosity rover that humans sent to Mars in the Earth era, this candle has worked far beyond the design life.

The design life of the Curiosity Mars rover is only a few months, but it has worked for several years, and until the destruction of the earth, it is still roaming on Mars. If it hadn't been for the big event of the collision between the wood and the moon, it would probably continue to work.

I have returned to the place where I was born and raised, and returned to the human cemetery. Xiao Yu thought silently. After staying here for a while. The Hope spacecraft began to move on.

Xiao Yu visited Neptune first, and Pluto and Uranus are on the other side of the sun at the moment. So Xiao Yu didn't see them for the time being. Looking at Neptune, which is as blue as the sea, some distant memories are being gradually opened up.

Xiao Yu didn't stay here for too long, and he didn't even observe Saturn and Jupiter in detail, although one of Xiao Yu's main goals was to stay on the construction base on Titan. Xiao Yu quickly passed through these places, passed through the asteroid belt that was as empty as the rest of the universe, and arrived at Mars.

Mars is still the same as when he left. The long period of 100,000 years has not brought any obvious changes to Mars, except that there are more meteorite impact craters on it. Mars is still the same as before, among the yellow sand all over the sky. Filled with a cold, dead, desolate breath.

In fact, every planet that Xiao Yu saw along the way had many traces of impact, even gaseous planets like Neptune were not spared, Xiao Yu still found many dark red impact spots on it .

Extremely high energy bursts and temperatures can cause changes in the composition of elements in the area, and differences in temperature can also cause this phenomenon. This means a change in color. And these color changes express the events of the past life in another way. By analyzing the size of these dark red spots and the composition of elements in the area, Xiao Yu can even deduce how big an asteroid hit this area.

There is no doubt that these asteroids all came from Earth orbit. The impact of the earth's explosion on the entire solar system is comprehensive and far-reaching. Frequent asteroid impacts will last for at least hundreds of millions of years, and it is during this period that the solar system will form a new balance.

Xiao Yu stayed above the orbit of Mars for a longer time. Xiao Yu hopes to find some traces of life on Mars. Even the rudimentary traces of life are good. It is entirely possible that the explosion of the earth is certainly a bad thing,

But in some respects, it also has some positive aspects. The earth is teeming with life, whether in the vast oceans or the skies. Mountains or jungles, caves or deserts. Earth is covered with life everywhere. After the explosion of the earth, these lives may not all be killed, and it is very likely that some species with tenacious vitality will survive. Under such circumstances, the earth will be transformed into a huge life seeding machine, carrying the fragments of life on the earth and embarking on a long interstellar voyage, sailing with the wind like a dandelion, Titan, Ganymede, Neptune Weiyi, Venus, Mars, these planets may become the second home of life on Earth.

But Xiao Yu was disappointed. During these 100,000 years, Mars has undoubtedly withstood hundreds of millions of earth debris impacts, but there is still no sign of life on Mars. It seems that the seeds from the earth have not been able to take root on Mars. This result made Xiao Yu a little disappointed.

After crossing the orbit of Mars, the former Earth orbit is ahead. Of course, there is no trace of the earth, replaced by a ring-shaped asteroid cluster. The evaporation of gas still hasn't stopped, and many asteroids still drag their long tails behind them. For example, after the explosion of the earth, the sea water will condense into an icy asteroid, and when it is blocked by other debris and not exposed to the sun, it will maintain a solid form, but if the orbit changes, the light from the sun will When it can directly hit its surface, the water will quickly evaporate, and under the action of light pressure and high-energy particles, it will float backwards and become a tail.

This is the comet.

The tails of countless comets completely cover this area, so that the sun is a little hazy from here. But Xiao Yu knew that this scene did not last long. On an astronomical scale, it can only exist for a very short time. After all, the total amount of steamable matter is limited, and when they are completely steamed by the sun, this place will become an ordinary asteroid belt, only a little denser, and there is nothing special about it.

The Hope spacecraft shuttles through the dense asteroid community. Some traces of the Earth era can still be seen on many asteroids, such as some special lime structures - which come from the remains of some buildings in the Earth era, and some special calcium phosphate structures - which come from large organisms in the Earth era skeleton.

A strange emotion was brewing in Xiao Yu's heart.

During the long shuttle, Xiao Yu discovered a somewhat strange phenomenon. There are some peculiar red colors on some asteroids containing water, and these red colors are appearing and disappearing according to certain rules. Specifically, when these places are irradiated by the sun, water vapor begins to evaporate in large quantities, and these red colors will appear quickly. When these places are blocked by other asteroids, making it impossible to receive sunlight, these red colors will appear. quickly disappeared.

This phenomenon aroused Xiao Yu's interest. Xiao Yu began to approach an asteroid to take a close observation of these reds. Xiao Yu manipulated the Hope spacecraft to push away a few asteroids blocking here, allowing this area to receive sunlight. Almost immediately, a large amount of water vapor emerged from the asteroid, and those hidden red colors began to appear quickly.

Xiao Yu manipulated the Hope spacecraft to block part of the sunlight shining here. Immediately, the red under the shadows began to disappear, while the red part began to increase in the area next to it that was still under direct sunlight. It appears that the red material that was originally in the shaded area was transferred to the sunlit area.

This is a kind of life. Xiao Yu thought silently, It has a strong phototaxis and thermotaxis. When there is sunlight, they will quickly become lively, and if there is no sunlight, they will quickly enter a kind of life. In a state similar to hibernation, to resist the cold in the universe.

As the Hope spacecraft got closer and closer, more and more details about this kind of life were detected by Xiao Yu. Xiao Yu discovered that this is a creature similar to algae, which seems to be a plant, but has the fast response mechanism of an animal.

Xiao Yu has been observing here silently, knowing everything about these creatures, watching them go from quiet to active, and then back to quiet from active. Chasing sunlight is their only mission. Sunlight brings energy. Sunlight will melt the water ice, release the rich nutrients frozen in the water ice, and mix them in the water vapor. Once the water vapor appears, it means that the food is safe arrival.

The amount of water ice on an asteroid is limited. When the water ice is consumed, how will they survive? They don't seem to have the ability to migrate between different asteroids. Xiao Yu thought, Under such circumstances, species that cannot migrate between different asteroids are not qualified to survive.

They are not real animals, have no feet, cannot travel between different asteroids, and even if they have feet, the distance between planets is not something they can cross. Most importantly, these creatures live on water ice, without which they die instantly. In the universe, there is no water ice.

Xiao Yu is observing here. Suddenly, another asteroid broke in and slammed into this asteroid. Accompanied by the impact, a large number of fragments were immediately splashed out. These splashed substances included stones, ice, and of course this algae-like red creature living in the ice.

These sputtered substances traveled here and there, some hit other asteroids, and some traveled through space. But Xiao Yu knew that based on the current material density of the Earth's asteroid belt, they are unlikely to break out of this range, and they will eventually fall on the rest of the asteroids.

Looking at the small rocks and ice that were splashed out like a goddess scattering flowers, Xiao Yu suddenly realized.

So that's the case, I understand.
