These are two different universes, so no matter how intense the explosion in the small universe is, it can't affect the larger universe.

Finally became a real seventh-level civilization, and easily wiped out all the members of the Andromeda Galaxies Alliance, Xiao Yu had nothing to do if he stayed here. However, Xiao Yu still plans to stay in the Andromeda Galaxy for a while, explore the entire Andromeda Galaxy, and enjoy the exotic scenery that is different from the Milky Way. After exploring the Andromeda Galaxy, go to the rest of the river system, or continue to explore, or find the rest of the seventh-level civilizations to communicate with each other.

The most advanced stellar-class warships built by Xiao Yu can reach a speed of 1,500 times the speed of light, and the slowest can also reach a speed of 1,200 times the speed of light. It wouldn't take Xiao Yu much time to explore the entire Andromeda Galaxy at this speed.

"Flame civilization, from this moment on, the entire Andromeda galaxy is yours. It's time for you to go. Xiao Yu said.

The time of separation has come, and Xiao Yu has no interest in starting his own cosmic exploration journey with the flame civilization. Every civilization should have its own independent development route, and Xiao Yu has no intention of changing this situation.

The Flame Civilization also seemed to know that separation was inevitable, and after a moment of silence, the Flame Civilization leader replied, "Thank you, Great Sweeper Civilization, if it weren't for you, our civilization would have been extinct now. What you will be on is a great cosmic journey, and at the moment our flame civilization does not have the ability to follow in your footsteps. We're gone, and we hope you have a smooth journey. At some point in the future, we may be following in your footsteps. Embark on the journey you've taken. ”

"I'm waiting for that day." Xiao Yu replied with a smile.

The flame civilization manipulated the fleet of its own civilization and slowly broke away from Xiao Yu's fleet, and entered the vast and deep universe with a curvature sailing, and disappeared from Xiao Yu's eyes.

Xiao Yu is in a good mood at the moment. A new door has been completely opened for Xiao Yu. Inside this gate, there are endless mysteries and riches waiting for Xiao Yu to explore.

"Maybe I shouldn't have been in such a hurry to get out of here." Xiao Yu pondered, "Energy may exist in different forms, whether it exists in the form of space or in the form of matter, it will only transform from one form to another, and will not disappear for no reason." So, after I detonate the entire space of the small universe. What will this little universe look like? It's an interesting question, and I might as well stay here and explore it while the explosion in the universe has subsided. ”

There seems to be a bit of a contradiction in saying this. Because the explosion happened in space. As people usually say, there was an explosion in a certain place and a certain place, and a certain place is a spatial concept. And at this moment, in this small universe, what is detonated is space itself. The space is gone. What else are you talking about explosions?

But Xiao Yu couldn't find the right words to describe this situation. After all. Space and matter in the small universe are energy, and although it has been transformed into other forms, it must still exist. What Xiao Yu wants to know is what kind of state it will exist in. Xiao Yu speculated that the three-dimensional universe may have experienced a similar situation at the beginning of its formation. Exploring the aftermath of this small universe will help Xiao Yu understand the true face of the three-dimensional universe.

When the small universe was still stable, the speed of time in the small universe was the same as that in the large universe, but now it has been destroyed. Even the existence of space is another matter, let alone time.

"Maybe the explosion there has already taken effect at this point." Xiao Yu pondered. began to explore the existence of that small universe through various sophisticated instruments, through gravity, space fluctuations, etc.

But the result disappointed Xiao Yu. It was as if the small universe had disappeared out of thin air, and no trace of its existence could be detected in the larger universe.

It's an incredible situation. Xiao Yu secretly pondered this question: "The four fundamental forces are the innate attributes of matter, and it is impossible for them to disappear. Pure energy does not exist, there must be space where there is energy, and there must be matter, so there must be gravity. But now I can't find any traces? This doesn't make sense. ”

Xiao Yu thought about a lot of unexpected situations, such as the displacement of this small universe in the four-dimensional direction due to the strong explosion, and it had left its original position, and because the distance was too far, Xiao Yu could not explore the traces, or the rest of the situation. The possibilities are endless, but Xiao Yu doesn't intend to give up just yet. Discovering the unknown, understanding the unknown, and solving the unknown are the standard processes of scientific and technological progress, and discovering the unexplained is a good thing for a technological civilization. If there is nothing unknown in this world, then it can only mean two situations, one is that the science and technology of this civilization has reached the peak of the universe, and he has fully understood this universe, and the other is that the scientific and technological development of this civilization has gone astray.

Where there is the unknown, there is the motivation to explore. Xiao Yu discovered the unknown this time, how could he let it go easily. At this moment, there was nothing urgent on Xiao Yu's shoulders, and Xiao Yu had a lot of time to explore here. Waiting until there is really no harvest before leaving will not make Xiao Yu lose anything. On the other hand, if something is found, it will be significant. Xiao Yu's technology is likely to make another leap forward because of this, entering a higher level of civilization.

So Xiao Yu's fleet stopped here. In order to verify whether it was due to a location deviation, Xiao Yu expanded his search range, exploring a vast area thousands of light-years away. In order to verify whether this phenomenon was caused by other reasons, Xiao Yu also made many other attempts, but the result was always the same, Xiao Yu never found anything.

"It can't be." Xiao Yu muttered to himself, "How could a small universe with a diameter of a thousand light-years disappear like this for no reason? Here, something must have happened that I don't yet understand. ”

Xiao Yu simply gave up his plan to explore the Andromeda Galaxy for the time being, and instead stationed here, while carrying out the research and development of the Cluster-class battleship, he was looking for traces of this small universe.

Because of the new stellar warship as the foundation, Xiao Yu's new warship manufacturing theory has basically matured. Building a Cluster-class battleship was a technical problem for Xiao Yu, not a scientific one.

Quantitative changes can also lead to qualitative changes, and in this respect, the Cluster-class warships are also fundamentally different from the various types of warships under them. Because the interior of a Cluster-class battleship is too large, large enough to fit an entire star system.

There is no small universe in a seventh-level civilization, and this was already realized when Xiao Yu first became a seventh-level civilization. The reason why the seventh-level civilization does not have a small universe like the sixth-level civilization is obviously not that the seventh-level civilization does not have the ability to create a small universe, but that the seventh-level civilization has no need to create a small universe at all. It's like a Cluster-class battleship, the space inside is so huge, what is the need to create a small universe?

However, this is only a general situation, and there may be special cases in this universe, and there may be a seventh-level civilization that specializes in the development of a small universe as the direction of civilization progress. These are all bad things to say. What strange thing in this universe can't happen?

Cluster-class ships are much more complex to build than Stellar-class ships, not only because of the higher requirements for construction materials, but also because they have to have a deep understanding of space. The current Xiao Yu is still a little bit behind.

So Xiao Yu turned to refining his space model and exploring more space. Once again, the Stellar Battleship Science has become the place that devours Xiao Yu's computing power the most. In the huge internal space of the Stellar Battleship Science, a large number of scientific instruments are in operation all the time, and a huge amount of scientific data is generated every minute and every second for Xiao Yu to analyze and study.

Xiao Yu's scientific and technological foundation has been steadily improving, and finally a key breakthrough has been made after 30 years. With this technological breakthrough, Xiao Yu's last obstacle to building a stellar-class battleship has also disappeared.

So Xiao Yu sent a fleet of voyages, carrying dozens of stars from the surrounding starry sky to come here, and with the help of rich material resources, Xiao Yu officially began the manufacturing of star cluster-class warships.

The Cluster-class battleship that Xiao Yu is planning has a hull about the size of a previous planetary-class spaceship, and has a speed of up to 1,600 times the speed of light. In addition, it has been greatly improved compared to stellar warships in many aspects such as defense, attack power, and instantaneous mobility.

In the process of manufacturing the Cluster-class battleship, Xiao Yu once again realized the most serious limitation of his scientific and technological progress.

"My computing power is still a little insufficient......," Xiao Yu sighed silently, "Although there have been many major breakthroughs in my computing technology in the past 100,000 years, in the face of the current new situation, the lack of computing power has still become the biggest shortcoming restricting my development." At present, I have not yet chosen my development direction, and there is already a lack of computing power, let alone reaching the seventh-level advanced civilization level, and it is time to choose all-round development. ”

"R&D of computing technology should be a priority. This is the foundation of all my scientific development, and without it there would be nothing. I don't know that there is a seventh-level civilization in this universe that does not have a computing direction, if such a type of civilization exists, it would be nice if I could obtain their computing science......" Xiao Yu thought secretly. (To be continued......)
