The 9,000-word chapter is presented to ...... Today's and yesterday's are all in it.

――――――――――――

During this period of copying materials, Xiao Yu has already begun the preliminary analysis of the scientific and technological data of microscopic civilizations. Of course, the data stored in the central computer of micro-civilization is not only related to science and technology, but also the rest of the humanities, history, observations, society and so on. Xiao Yu copied these materials together.

Since a seventh-level civilization has possessed writing and the ability to record the history of its own civilization, it has developed to the current historical process, which also has great reference significance for Xiao Yu. From these materials, Xiao Yu learned that the microscopic civilization originally originated from another supercluster, which was more than 60 million light-years away from the Virgo supercluster where Xiao Yu lived. The microcosmic civilization has become a seventh-level advanced civilization for nearly 10 million years, and in this nearly 10 million years of history, the microcosm civilization has traveled tens of thousands of river systems, and has made relevant records for each of these river systems, and Xiao Yu is naturally very interested in these materials.

However, Xiao Yu is more interested in another part of the information. That part of the information is about the micro-civilization in the course of nearly 10 million years of travel, the record of the civilization encountered. Microscopic civilizations have encountered many civilizations, and the level of science and technology of these civilizations has been high and low, and there are even a few eighth-level civilizations. However, there are many fewer records of these eighth-level civilizations in micro civilizations, and there are many speculative elements in them. I think it should be because the microscopic civilization can't understand too much about these eighth-level civilizations.

But there is one thing that is a pity, and that is. The information obtained by Xiao Yu is incomplete, and there are many faults and omissions in these records. However, this is also an understandable thing, the microscopic civilization fleet I encountered is not the main fleet of this civilization - the main fleet of microscopic civilization is already in the Big Magellanic system. With the rebirth of the Great Magellanic system, it was destroyed.

However, the most critical part of the technology is not too much missing. Xiao Yu learned about the scientific and technological development process of the micro civilization, the situation encountered by the micro civilization when it chose the direction of development after becoming a seventh-level civilization, and how they evolved their bodies to such a small size step by step.

"Technology is only a tool in the hands of intelligent beings, but this tool has fundamentally changed intelligent beings themselves." Xiao Yu sighed secretly, "Step by step, start from the type of intelligent creature of normal size to make your body smaller and smaller." Then, it directly intervenes in the evolution of the body through technological instruments, and finally transplants only the organs responsible for thinking into the machine, and then slowly develops...... Every seventh-level civilization has a heroic story. The same is true of micro-civilizations. ”

Although it belongs to the hostile camp with the microscopic civilization, although the main body of the microscopic civilization has been eliminated by itself, this does not affect Xiao Yu's sigh and respect for the development process of a civilization.

"The seventh-level civilization is really a watershed. Before becoming a seventh-level civilization, the microcosmic civilization was the same as the sixth- or fifth-level civilization I had encountered. There is only a small difference - nothing more than a small difference in the details of technology. However, after becoming a seventh-level civilization, the development of civilizations began to develop in a blowout manner, and the gap between different civilizations was unimaginably large. Just like this civilization recorded in the micro civilization - the macro civilization? Every intelligent creature within a civilization has a huge body, some of which are the size of a planet...... This is really hard to imagine, I wonder if this macro civilization has integrated the technology obtained from the research of alien beasts in the process of its own development? The development of his body is getting bigger and bigger, which seems to be similar to that of a strange beast. ”

"Hmm...... Sure enough, there is also a civilization in the direction of the great universe. Specializing in the development of small universes as the direction of scientific and technological progress of their civilization, their small universes may include an entire river system. I don't know if the civilization in the direction of the big universe has carried out research and progress in the reconstruction of the rules of the small universe? I'm afraid that the seventh-level Great Universe Civilization doesn't have this ability yet. The eighth-level ones can't be said to be good. Xiao Yu thought silently.

Xiao Yu has already come into contact with the mystery of the rules a little, since he has destroyed a small universe. If this small universe can be brought back to chaos along with its internal rules, then there will inevitably be a way to re-establish the rules in it. Perhaps, there will really be a civilization that has built a small universe that works completely according to its own wishes, and in this small universe, all the rules can be changed by them according to their own needs. Among the types of civilizations that Xiao Yu knows at present, the civilization in the direction of the universe is the closest to his own speculation.

"One more point...... Civilizations were indeed similar in the embryonic period, and the initial stage of the development of this microcosmic civilization, like that of humans in the Earth Age, also experienced the Steam Age and the Electric Age, and finally reached the atomic Age. These basic technologies are the same, but the application of technology is a little different because of the differences in civilization customs and body structure. ”

"Let's take a look at their computer technology...... Let's see what I can learn from your computing technology......" Xiao Yu roughly flipped through the information obtained from the microscopic civilization, and finally set his eyes on computing technology. Computing technology has always been the technology that Xiao Yu is most interested in, and it is also the foundation and foundation of Xiao Yu's development of all other technologies.

With the issuance of an order in Xiao Yu's mind, immediately, among all the scientific and technological information of the microscopic civilization that Xiao Yu obtained, all the computer technology related to computer technology was presented in front of Xiao Yu.

"Their computer technology is not as advanced as mine, and even their overall performance is not as good as mine. But it doesn't matter, they take a different path than me, and these things inspire me a lot. Kindness? By continuously reducing the size of the computer to shorten the response time, and indirectly improve the computing speed? It's a good idea, and it's worth learning from. ”

"With the help of your own microscopic technology, you can directly engrave computing elements on microscopic particles such as atoms or molecules? With the help of different molecular and atomic structures of different substances, different use arrangements have been made accordingly? That's a good idea. ”

Xiao Yu only felt that his horizons had been greatly broadened. Just a cursory glance. Without conducting a detailed scientific and technological analysis, Xiao Yu came to a preliminary conclusion, that is. After comprehensively digesting the technology of microscopic civilization, the performance of one's own computer will be increased by at least 80 percent.

This is the power of the combination of technology from two different types of civilizations. Eighty percent is the most conservative estimate, and the final result is likely to be much more than that, and it is not a question of one plus one equaling two, and the combined technology of the two civilizations is likely to be much more powerful than two.

This is the first technology that Xiao Yu has obtained from the rest of the seventh-level civilizations. This point also caused Xiao Yu to think a little.

"Micro-civilizations have said that the Guardians are using forceful means to maintain peace between advanced civilizations. It is precisely for this reason that among the seventh-level civilizations, a large number of non-war civilizations have appeared. Maybe...... It is precisely because of the problem that one plus one is greater than two that the defenders strictly forbid wars between the higher civilizations - because it is obvious. War is the best way to promote the integration of civilization and technology. But. It is precisely because of this reason that those interest-based civilizations have lost their combat effectiveness and self-preservation ability too much. If there is a war-type civilization that defeats the rest of the interest civilizations in large numbers and obtains a large number of different types of technology, doesn't that mean that this war-type civilization can develop in an all-round way? Xiao Yu thought about this question silently. This thought made Xiao Yu's heart flutter. But then, Xiao Yu denied this idea: "The seventh-level civilization of the war type must definitely be the top priority of the guardian's surveillance. There is no way that the apologists will let this happen. But...... Since the Guardians are no longer capable of defending peace between the higher civilizations with force, then. This seemed like an excellent opportunity for me. ”

"That'...... What about the war between me and the microscopic civilization? This is also a war in the category of seventh-level civilizations. Xiao Yu remembered another question, and felt a little worried in his heart. However, he immediately dispelled: "There should be no problem with this, in this incident, after all, I have assumed the responsibility of the executor and helped the defender to improve the law of cause and effect." Perhaps because it's good for the defenders as well, all the defenders acquiesced to letting me get a little bit of good. ”

This is a very possible thing, but it also means that if Xiao Yu takes the initiative to take action against the rest of the interest civilizations in the future, Xiao Yu's luck may not be so good, and Xiao Yu is likely to be directly interfered with by the defenders.

"Let's talk about it later." Xiao Yu thought secretly, "If the technology of that civilization is attractive enough to me, I don't mind taking a risk. ”

By this time, all the scientific and technological data of the microcosmic civilization had been collected, and the nearly a million microscopic civilization spaceships had no value for Xiao Yu.

"Let's go." Xiao Yu said, "I keep my promise and will not hurt you again." I'm leaving, I'm going to continue my own journey, the universe is so big, I guess it's hard for us to meet again in the future. ”

The microcosm of civilization was silent and half-silent. After that, Xiao Yu received a reply: "Finally, I will send you a word, Xiao Yu, this sentence is not recorded in our central computer." Think of it as a reward for keeping your promise to let us go. ”

"What?" Xiao Yu asked.

The message of the microcosm civilization is full of sighs: "The development of war-type civilization has always been suppressed by defenders, and every war-type civilization will encounter many, countless disasters. You have to be careful later. ”

Xiao Yu has opened the spatial labyrinth and opened the way for the microscopic civilization to leave. After the passage was opened, nearly a million spaceships of the microscopic civilization immediately left here and came into the outer universe, quickly disappearing without a trace.

But Xiao Yu knew that they hadn't left yet, and they were still wandering outside their spaceship.

"Since it is a war-type civilization, it will surely perish because of war if it relies on war for development. This is the fate of all war-type civilizations in the universe so far. War-type civilizations are like meteors across the sky, although they are gorgeous, they cannot last long. You are still only a seventh-level primary civilization, and after becoming a seventh-level advanced civilization and having the qualifications to choose your own development direction, you still have to think about this issue. Micro Civilization said.

"Hmph." Xiao Yu snorted with some disdain. "Don't tell me that the civilizations in the Rebel Alliance are all non-war interest civilizations. Why weren't they destroyed according to your fate? ”

"What you don't understand, what you don't understand......" responded to Xiao Yu. It was the faint sigh of the microcosm civilization, "You will understand later...... Here we go...... Goodbye......"

The faint spatial fluctuation vanished. Xiao Yu knew that this was because the microscopic civilization had gone far away and was out of the scope of his own exploration.

"Pretending to be a ghost." Xiao Yu snorted coldly, "What if I understand?" I will not become a seventh-level civilization of the war type, nor will I become a seventh-level civilization of the interest type, I will become a type of civilization that you cannot imagine...... I will be all-round development. Whether it is war or interest, the science and technology of all civilizations have been mastered in an all-round way......"

Xiao Yu has obtained a lot of scientific and technological information about microscopic civilizations, but it is a pity that there is one point about the defenders. However, there is less information about the secrets of the universe such as the rebels. Come to think of it, this is also because this fleet is not the main fleet. However, just the information obtained so far is also a big gain, which is enough for Xiao Yu to analyze and digest it for a lot of time.

"One last thing, it's time to go." Xiao Yu sighed secretly. Begin to slowly launch your own fleet. Slowly increase your speed and move towards your predetermined goal.

What awaits Xiao Yu ahead is a long journey that lasts for 7,000 years. Among all known civilizations of the local galaxy group, Xiao Yu is the second civilization to sail across the galaxy group after the Guardian civilization.

Xiao Yu was not interested in this title, and no one else would know about it anyway.

Hundreds of years after his departure, Xiao Yu once again crossed the Andromeda Galaxy. However, this time Xiao Yu did not enter the Andromeda Galaxy again. Passing through the Andromeda Galaxy is purely a matter of course.

After crossing the Andromeda Galaxy, there will no longer be any large river systems in front of Xiao Yu in the local galaxy group, and some will only be a few dim satellite river systems of the Andromeda Galaxy. For example, Andromeda I, Andromeda II. M32, M110, etc.

Xiao Yu changed his course slightly, allowing his route to cross as many of these rivers as possible. While crossing these river systems, Xiao Yu made some observations of these river systems by the way. Some of these river systems are desolate, while others are young and vibrant. In these river systems, Xiao Yu also discovered some other civilizations, but the scientific and technological progress of these civilizations was not high enough. Xiao Yu had no interest in making contact with these civilizations, no matter what they were doing at the moment, what kind of situation they were in, whether they were thriving or living or dying, Xiao Yu did not show up. When observing these river systems, Xiao Yu only played the role of a bystander.

These civilizations will certainly not know that not long ago, a seventh-level civilization that has truly stepped onto the cosmic stage passed through their territory.

After passing through the last fairy in the direction of the Maffei Group, a member of the Milky Way Group, Andromeda IV, Xiao Yu completely left the group.

Andromeda IV is a dwarf irregular galaxy. Dwarf means that it is small, and irregular means that the stars inside it and the overall appearance of the river system show irregular shapes. It does not form a few distinct cantilevers like spiral or barred spiral galaxies, nor does it have a roughly circular appearance like elliptical galaxies. It's just an irregular galaxy.

It has less than 100 million stars inside, and the dust clouds inside the river system are very rare. This means that the ability of this river system to make new stars is very weak, and without new stars to replenish it, the original stars will inevitably dim over time, or become white dwarfs or neutron stars or black holes, and this river system is destined to dim and eventually become a desolate and dead place where only extreme stars exist.

If the majority of extreme stars occupy a river system, and the number of stars representing survival and hope is reduced below a certain limit, the river system will be completely annihilated in the starry sky, and it is unlikely that the rest of the civilizations will find it again. It's like a man-eating monster hidden in the darkness, quietly waiting for anyone to intrude into its sphere of influence.

Or when a star dies, such as a red giant, the outer layers of the star will spread into the universe, and when it becomes a neutron star or a black hole, a supernova explosion will eventually spread out a lot of stellar material, but there is one point that is very important. That's where the dust is distributed -- the dust slowly spreads around the position of the parent star, and it is difficult for it to merge with the rest of the dust. In other words, it is also quite difficult to rely on this dust to form the next generation of stars.

It's a desolate, dead silence. A small, hopeless river system. Just as the frontiers of those nations in the age of Earth were always desolate, so are the frontiers of the Fairy-Milky Way Group.

After passing Andromeda IV, Xiao Yu completely lost a large mass aggregate in front of him, and even no macroscopic matter. There are no stars, no planets, and no galaxies and rivers.

Xiao Yu's environment. The density of matter is pitiful. Compared to this one, star systems, such as the so-called vacuum zone inside the solar system. It's like a rich man compared to here. Here, the density of matter has reached an unprecedented point where there is only one atom per 100 cubic meters. This is equivalent to the density of matter that spreads a drop of water evenly across a space of six million cubic kilometers.

This is also because it is not too far away from the Milky Way-Andromeda Group. Xiao Yu believes that as he gets farther and farther away from his own galaxy group, the density of matter will further decrease.

It seems that Xiao Yu is the only one left in the entire universe. In this boundless and lonely universe. Only Xiao Yu's fleet was sailing. Ahead, there was a distance of hundreds of millions of light years at every turn, and in such a long distance, Xiao Yu could not touch any macroscopic matter other than his own fleet.

Probably, since the dawn of the universe, no civilization has ever arrived in this place, and no stars have ever arrived.

Loneliness is the norm here, but after the extreme thinning of the material. But it may contain some other mysteries, as well as some physical phenomena that Xiao Yu is very interested in.

The big universe is stable. Both stars and planets have their own orbits, and the chaos of certain river systems or certain star systems, such as meteorites flying around, cannot affect the overall stability of the universe. It seems that the universe is predictable.

But after coming to this environment close to an absolute vacuum, part of the truth of the universe was exposed in front of Xiao Yu. Here, Xiao Yu can easily perceive one point, that is, the universe is not calm, and some things here do not all abide by the rules of the universe.

For example, virtual particle pairs. This is something that belongs to the microcosm, and it just so happens that among the scientific and technological data obtained from the microcosm civilization, there are many studies on these phenomena.

There's not nothing in the vacuum, and it can be hilarious.

In a vacuum, there will be a large number of particles that suddenly appear in the original empty place, without any reason or pattern, after appearing, they will only exist for a very short time, and then they will both disappear and disappear. This can happen anywhere. It seems that the laws of the universe have failed here.

Here, mass and energy are not conserved. It is only because of their relatively short existence that the conservation of mass and energy of the universe as a whole is maintained.

This kind of thing, even Xiao Yu doesn't have the ability to explain it perfectly. Xiao Yu guessed that maybe after he had insight into all these things, his technology would make another leap forward.

Time slipped away in this boundless emptiness. In the blink of an eye, thousands of years have passed, and Xiao Yu has finally reached the true edge of the fairy, the Milky Way galaxy group.

The edge here is that after crossing here, the gravitational pull from the fairy-galaxy group of galaxies will no longer dominate, but the gravitational pull of the rest of the river systems will start to dominate here, even though there is nothing here at all.

For the first time, the gravitational pull of the remaining groups of galaxies overwhelmed the gravitational pull of the local group. Perhaps this kind of gravitational competition is meaningless at all - you know, in a position, because the distance is too far, the gravitational pull of hundreds of river systems, countless stars, black holes, neutron stars and other stars in this galaxy group is not as great as the gravitational force of a spaceship next to Xiao Yu, but this is a way to divide the territory of different galaxy groups after all.

"Just as Armstrong left the Earth for the first time and stepped on the moon, just as I left the solar system for the first time and reached the Tianyuan Four Galaxy, just as I left the Milky Way and entered the Big Magellanic Galaxy for the first time, and now, for the first time, I left my own group of galaxies and entered the territory of another group of galaxies, the Maffei Group. I'm coming. Xiao Yu said to himself silently in his heart.

"Perhaps, in the future, I will have the opportunity to leave the Virgo Supercluster for the first time and enter the rest of the Superclusters. Perhaps, for the first time, I will have the opportunity to leave the Supercluster Complex and enter the rest of the Supercluster Complex...... This vast universe has infinite possibilities, and so does my future......"

Here, it is six million light-years away from the Milky Way, 4.8 million light-years from the Andromeda Galaxy, and within the Maffei Cluster of Galaxies. The closest river system to itself is more than four million light-years away.

The sky that Xiao Yu could observe entered the darkest period. In terms of naked eyesight, in this position. No matter which direction you look, you can't see a few stars. A few dim points of light make up the entire field of vision.

Even these few dim spots of light are not ordinary. Every dim point of light that is not as bright as a random star in the night sky above the earth is actually a river system. And it's a very big and bright river system. Millions of light-years away hide all the details of these river systems. Their splendor and magnificence, and their enormity, are all diminished in the darkness, and only a dim point of light is displayed to the observers.

The Milky Way cannot be seen here with naked eyesight, and the Andromeda Galaxy requires the exertion of a person with good eyesight to see it. It's a long way off. And Xiao Yu's target, the Mafei galaxy group, is a little more miserable. The largest river system in the Maffei Group, Maffei I is not even comparable in size to the Triangulum Galaxy, and it is naturally impossible to see it in this unknown.

In front of Xiao Yu was a real nothingness, and there seemed to be nothing in front of him. There's just darkness. Xiao Yu is moving towards this nothingness. The telescope is like the sharpest scalpel, allowing Xiao Yu to tear through all the obstacles laid by the universe with the help of a long distance. Find what you're looking for. Although he couldn't see anything ahead with the naked eye, Xiao Yu knew that as long as he continued to sail, he would encounter another wonderful thing in thousands of years. There, there will be warm stars, gracious planets, huge river systems, everything you want.

In these thousands of years, with the help of scientific and technological information obtained from microscopic civilization, Xiao Yu's science and technology have once again begun to progress. Of course, the most obvious progress is in computing technology. In fact, just as Xiao Yu expected, after integrating the technology of microscopic civilization, the average performance of the computer equipment he made increased by 300% compared with before.

Xiao Yu, who has more computing power, began to analyze the rest of the technology with more powerful force, as well as the research and development of his own technology. Even, after analyzing and digesting the technology of some microscopic civilizations, Xiao Yu also made further research on the basis of microscopic civilizations. Xiao Yu is sure that at this moment, even if the micro civilization comes to compare with himself with the micro technology, he will definitely win.

This is Xiao Yu's excellence. Any technology, as long as you look at it, can be immediately understood, digested, and truly become your own. This is also Xiao Yu's confidence in the future.

Time was still slowly passing, and the starry sky in front of me was always the same, always empty and dark. But in this darkness, Xiao Yu made a new discovery.

Xiao Yu found a point of light. Perhaps it was because the observation force was only aimed at Mafei I and the rest of the large river systems, as well as some of the more important targets in the celestial sphere, until the brightness of this light point increased to a certain extent with the shortening of the distance, and it was discovered by Xiao Yu's non-stop survey observation system.

The non-stop survey observation system has been observing the entire celestial sphere at all times and at all times, and has never stopped. Xiao Yu uses this system to monitor any movement in the universe at any time, such as where gamma-ray bursts occur, where there is information storms, where there are supernova explosions and so on. However, since it is uninterrupted and all-celestial, the observation accuracy of this system must not be too strong. So it wasn't until now that Xiao Yu discovered this point of light. After discovering this unexpected point of light, Xiao Yu immediately mobilized his elite observation force and aimed at this location.

This point of light had never been seen in Xiao Yu's previous records. Although this area has been observed many times, Xiao Yu has never discovered it before. This means that it must be small and dark.

Further observations confirmed Xiao Yu's suspicions. It's a very small and bleak river system, or rather it's not a river system. It's just a separate star cluster.

It's really too small -- there are only a few thousand stars inside it, and it occupies less than 200 light-years of space. Such a little thing. It's really not appropriate to say it's a river system. Moreover, Xiao Yu discovered the most amazing point, that is, there is no black hole with absolute mass dominance inside this little guy to dominate all this. It seems that these thousands of stars simply rely on their own gravitational pull to maintain the stability of the group.

At this moment, this small stellar group is only a few hundred years away from Xiao Yu. Xiao Yu has always been very interested in such weird things. So Xiao Yu adjusted his course a little again and drove towards the small group.

The discovery of this little guy changed the name of the river system closest to Xiao Yu in the Maffei galaxy group. From another river system was transferred to the head of this small group. This small group is only a few hundred years away from Xiao Yu, and it is still nearly a thousand years away from Ma Feiyi. It is detached from the Maffei Cluster and is moving away from the Maffei Group at an extremely high speed, towards the Fairy-Milky Way Group.

It's a lost creek system. It's like being in the middle of the Milky Way. The wandering planets that Xiao Yu once encountered without a star belonging. It is also a wandering river system.

After hundreds of years, Xiao Yu arrived in this river system. After Xiao Yu's voyage lasted for nearly 6,000 years, in this distant foreign land, Xiao Yu finally came into contact with macroscopic matter again—glowing stars, planets with stable orbits, and energetic asteroids.

Xiao Yu carried out a detailed observation of this small river system, anyway, it was so big in total, and it would not take Xiao Yu long to observe in detail. Xiao Yu discovered. There are almost no clouds of gas and dust in this river system, and most of the stars inside it are more than 10 billion years old.

This means: For at least nearly eight billion years, no new stars have been born in this small river system. Another thing is very strange, Xiao Yu found that the stars in this small river system seem to be divided into two factions, and the two factions have great differences in terms of element composition and star type.

These two groups of stars could not have formed in the same place, and it is unlikely that they were formed in the same river system.

Gradually, Xiao Yu had a guess in his heart about the formation of this river system.

It may be that more than 10 billion years ago, or even more far, these stars were scattered in different parts or in different river systems and orbited according to their orbits. But the collision of rivers broke the calm. This is a gravitational battle between two river systems, and in this collision, the black hole at the center of the river system will be affected by the gravitational pull very violently, and they will even gradually get closer and eventually merge into an even larger black hole. In this fierce gravitational battle, these stars, which originally did not belong to the same river system, came together by mistake, bound by their own gravity to form an open star cluster.

The star cluster is a celestial body composition unit that is one level lower than the river system and one level higher than the star system, and the largest warship Xiao Yu has made at the moment is a star cluster-class battleship that is larger than the stellar class battleship. There may be a few stars in a star cluster, or there may be tens of thousands of stars. For example, the Pleiades star cluster, the Pleiades star cluster and the Hive Cluster in the Milky Way. Star clusters can be classified into globular clusters and open clusters according to their type. The small river system in front of you, if it is in the Milky Way or the Andromeda Galaxy, will belong to the category of open star clusters.

After the formation of the open cluster, the gravitational battle between the two large river systems continued, and eventually threw the newly formed open cluster out of the river system. From this moment on, it left its homeland and began to wander.

After some calculations, Xiao Yu came to the conclusion that after the infinite time in the future, if it was lucky enough, it might be captured by the Triangulum Galaxy and eventually merge with the Triangulum Galaxy.

"What a funny little guy." Xiao Yu thought with some regret, "There are billions of time waiting for you ahead, good luck." Unfortunately, I don't have enough time to stay here. ”

Xiao Yu's fleet slowly left the lost river system and continued to sail forward. The Maffei One galaxy is just ahead. (To be continued......)

PS: I ran thousands of miles today, and finally arrived at home, and I started to hurry up and code words without eating, and finally finished writing at this time...... Whew, Rainbow goes to rest and eat something first.
