At this moment, at least forty percent of the scientific research resources of the Shenzhou civilization are poured into the associated ghost clan. In addition, the power is still placed by Xiao Yu in conventional scientific research.

It is very unwise to put all the eggs in one basket, and Xiao Yu is deeply aware of this. So Xiao Yu did not relax his research on conventional technology. Xiao Yu's goal is also very clear, in terms of conventional scientific research, Xiao Yu will aim to create a stellar warship. After creating a stellar battleship, Xiao Yu will return to the galaxy.

Stellar-level warships are the most powerful weapons of war under the seventh-level civilization, and they are also the symbol of the sixth-level peak civilization. In Xiao Yu's speculation, the stellar-class battleship is also the most massive battleship. Xiao Yu believes that for civilizations of the seventh level or above, the increasing volume will no longer be able to bring about the matching performance improvement, and the use of perfect space technology will be able to bring about an effect of "accepting Sumeru in mustard seeds", and through space technology, the space in a village-level spaceship may be larger than a star system. On the other hand, an ordinary village-level spaceship may be the flagship of a seventh-level or higher civilization.

Neutron Battlestar is a good representative of this. The Neutron Battlestar is at least a Cluster-class battleship, and it may also be a higher-level River-class battleship, but its volume is just like that, probably only equivalent to the size of Xiao Yu's provincial and municipal warships.

However, there are still many very serious technical obstacles to the creation of stellar-class warships for Xiao Yu now. The most fundamental point is the limitation of material technology. Hydrogen atom polymerization materials are not capable of manufacturing stellar-class warships, although the flesh and blood of the Tree Clan Alien Beast and the Python Alien Beast can be competent for this, but some key parts of the stellar-class battleship cannot be made of alien beast flesh and blood. In addition to the limitations of material technology, the rest of the technological obstacles are even more numerous.

Through the analysis and study of the fragments of the stellar warship of the Guardian Civilization, Xiao Yu confirmed. The materials used to make stellar-class warships have gone beyond the category of elemental atomic polymerization materials. It seems to be a fusion of simple microscopic particles such as neutrons, protons, and electrons, and has lost the properties of the elements. The performance of this material can even be compared to the flesh and blood of the white dwarf alien beast that Xiao Yu once obtained.

Although that white dwarf alien beast was not as powerful as the Tree Clan alien beast or the python alien beast, it was also a sixth-level alien beast anyway. And through scientific and technological means, the difficulty of creating materials with properties no less than the flesh and blood of sixth-level alien beasts can be imagined.

"It's really not a simple matter to build a stellar-class battleship." Xiao Yu sighed, "Stellar-class battleships are the ultimate in volume, and they are already fundamentally different from planetary-level battleships. Suffice it to say, there are no stellar ships. It's not even the top existence in the galaxy. It's difficult to build a stellar battleship, but I still have a lot of time, and I have the confidence to build a stellar battleship. ”

Just when Xiao Yu was running his huge computing power to the extreme and making every effort to conduct scientific research in all aspects, Xiao Yu received a report from scientists from the Academy of Materials Science Sciences.

"The hosts. When it comes to materials science, we have a recent discovery. The chief scientist of the Academy of Materials Science said in the report. Stellar-class battleships are constructed from microscopic particle polymerization materials. And now, although we have the fragments of warships of the Guardian civilization as samples, we have never been able to find a way to make this material. But now, we have found that this material seems to have evolved naturally from the cosmic environment, if we can find a natural processing plant for this material in the universe. By observing and analyzing the mechanism of its natural formation, we have a great possibility of being inspired to grasp how this material is made......"

"Huh?" Xiao Yu's heart moved, and he immediately extended his computing power to the Academy of Materials Science Sciences. I copied the latest research results of the scientists of the School of Materials Science into my mind. After a moment, Xiao Yu responded: "Very good, then let's set off towards the Spider Nebula." ”

Scientists from the School of Materials Science have discovered that in some drastic astronomical phenomena, this microscopic particle polymerization material may be produced through natural evolution. Among them, the astronomical phenomenon that is most likely to produce this material is the fusion of stars. The collision of stars under certain conditions will not lead to destruction, but to new life. The two colliding stars will eventually merge into a larger, heavier star, and in the midst of this violent fusion reaction, there is a high probability that microscopic particle polymers will be created.

And when it comes to star fusion, the most suitable place is the Spider Nebula. The Spider Nebula is a star-dense site in the Great Magellanic System, and within it there are many huge stars that are apparently created by star fusion. Xiao Yu is convinced that in the mechanism of natural evolution of stars, it is impossible to give birth to stars larger than 120 times the mass of the sun, and there are many stars with more than 200 times the mass of the sun in the spider nebula. Since they were not born through natural evolutionary mechanisms, they could only have been created through stellar fusion.

For Xiao Yu, the Spider Nebula is the most suitable place to study. So Xiao Yu controlled his fleet, as well as the small universe, and began to set off towards the Spider Nebula.

The Spider Nebula is only about a thousand light years away from Xiao Yu at this moment, and it only takes about seven years for Xiao Yu to reach the Spider Nebula. And even at such a distance, the Spider Nebula still shows an astonishing brightness.

The stellar activity inside the Spider Nebula is too strong, and there are too many extreme stars, and there are many stars that are close to the limit of Eddington's luminosity alone. The Eddington luminosity limit is the brightest luminosity that a star can reach, it is not a fixed value, its size is related to the mass of the star. If the luminosity of a star exceeds the Eddington luminosity limit, the radiation pressure caused by the light will exceed the gravitational pull of the star itself, and a large amount of matter will be projected into the universe by the star under the action of light pressure, which will cause the luminosity of the star to dim. Therefore, the luminosity of a star can briefly exceed the Eddington luminosity limit, but it cannot maintain this state for a long time.

The force of light pressure exceeds the gravitational pull of the star itself, which then causes the star to produce a massive ejection of matter, and you can imagine how bright the star would be in this case, and how bright the entire Spider Nebula would be. For example, if the Spider Nebula is placed a thousand light-years away from Earth, the brightness of the Spider Nebula can make a visible shadow of humans on Earth. The Spider Nebula is powerful. What Xiao Yu is going to is such an extreme place.

Sailing alone in this unfamiliar galaxy, Xiao Yu's mood gradually calmed down. Sweepers, guardians, Taihao, alien beasts, all kinds of powerful existences flashed in Xiao Yu's heart one by one.

"If I can find a way to let the ghosts manipulate the corpse of the MSI civilization without damage, then after I return to the galaxy, the first thing I have to deal with is the Guardian civilization, even if I don't have the strength to wipe out the Guardian civilization, then at least I have to obtain their technology. The technology of the Guardian civilization and the corpse of the MSI civilization will bring me to the peak of my strength, and then it will be time to fight the Sweepers......"

Whether or not to start a decisive battle with the Sweeper Civilization is not something that Xiao Yu can decide. Even if Xiao Yu hoped to coexist peacefully with the Sweeper Civilization, it was useless, because the Sweeper Civilization had spent such a huge amount of effort to cultivate Xiao Yu, and the ultimate goal was to eliminate Xiao Yu when Xiao Yu was at his strongest. This is something that has long been predestined and no one can change it.

Xiao Yu is moving forward according to the route set by the Sweeper Civilization, because Xiao Yu believes that this behavior is in his own interests. The Sweeper Civilization is confident that it will wipe out Xiao Yu in the most powerful period, and Xiao Yu is also confident that he will win the decisive battle with the Sweeper Civilization. This is destined to be the largest battle in the history of the galaxy, and this battle will determine the fate of at least five top existences.

During the long journey, Xiao Yu passed through one galaxy after another, feeling the difference between the Big Magellanic Galaxy and the Milky Way. These different natural landscapes and different human environments will become Xiao Yu's accumulation and be recorded by Xiao Yu.

Xiao Yu saw that after the Great Emperor's civilization was wiped out by himself, the Big Magellanic Galaxy had completely regained its calm. Along the way, I have seen at least a dozen fleets of different civilizations and three trading places of different civilizations. Just as the Solan civilization said, the different civilizations in the Big Magellanic system have realized their original dreams, and all civilizations are living in peace and working together to develop their own technology.

"This is the ideal state. The exchange between science and technology does not necessarily have to be achieved through war, but can also be achieved through equal trade. It's a shame, why isn't this happening in the galaxy? But to achieve this exchange through the most brutal war? ”

If he could, Xiao Yu was very reluctant to choose war.

"The Big Magellanic Galaxy can also be regarded as a testing ground, let me see how far the civilizations of the Big Magellanic System, which have chosen peace as the direction of development, will eventually go......

A few years have passed, and Xiao Yu has come to the vicinity of the Spider Nebula. When Xiao Yu broke away from the curvature of the voyage, what appeared in front of Xiao Yu was a spectacular scene.

Xiao Yu's fleet was instantly overwhelmed by the infinite light. (To be continued......)
