In the middle of the Alliance Space, Hu Yu saw a huge building. The building was only a little over 5,000 meters high and wide, but hundreds of thousands of kilometers long. If one end of this building were placed on Earth, the other end could reach the Moon and be much longer.
The Erguan explained that this was the research center for the entire Alliance Space. Scientists from all civilized beings lived in this building, and each civilization could obtain enough space according to its needs. The reason why everyone was willing to be here was that scientists from several Great Star Region Civilization would occasionally conduct various experiments in the surrounding airspace. Hu Yu smiled and understood. Everyone wanted to glean some clues about technology, which would be very inspiring for their research.
Upon returning to Earth Hu Yu immediately informed several academicians and generals about the Alliance Space situation, especially the Andromeda Civilization. While everyone was surprised, they also felt a chill. However, Hu Yu told them not to worry, as several Great Star Region Advanced Civilization must have deployed warning systems in distant airspace. The Alliance and other self-developed Small Star Sector Civilization had enough time to relocate. It was just that other cultivated civilizations would only find out when the Andromeda Civilization attacked.
The next step was to arrange the migration of these cultivated civilizations. The Alliance's territory was vast, and accommodating 150,000 Small Star Sector Civilization wasn't too crowded. However, no civilization dared to disobey the joint order issued by the Great Star Region Advanced Civilization. Although they would be closer to the Zerg swarm there, there was a defensive line in place. As long as the defensive line didn't collapse, everything would be fine. If the defensive line collapsed, it would be the same anywhere in the galaxy.
In addition, the Great Star Region Civilization also offered competitive rewards, including territory rewards and technology rewards. This made all the cultivated civilizations willing to migrate to the target airspace. More importantly, the resources there are now unimaginably abundant, with various warship wrecks and insect corpses, all of which are excellent materials. The earlier you go, the more you will get.
Although the energy from the neutron star cluster explosion is still sweeping away into the distance, these civilizations' fleets are capable of protecting the stars and planets that have not been destroyed. Moreover, the Great Star Region Civilization also allow them to move some planets there, where there is no difference in survival for the civilized beings compared to living on this side of the galaxy.
As these civilizations rushed to migrate to the new airspace, only more than 300 Star System-Level Civilization remained in the once bustling airspace. Some civilizations that had been nurtured with technology but had not grown into Small Star Sector Civilization were also required to migrate. Only civilizations that had developed on their own were not allowed to go.
Hu Yu was initially somewhat worried that they might be unwilling, but what Hu Yu didn't know was that there was an even more important reason why these civilizations were so eager to move away: once they reached the new airspace, there would be no longer any of these real Small Star Sector Civilization to supervise them.
They can also secretly research technology, manufacture key components for warships, and strengthen themselves. Dozens of civilizations are Li Shun's Fortress Civilization. These civilizations have reached a deeper cooperation with Li Shun and have also obtained some of the technology from the Great Star Region Civilization. This technology is enough for them to become powerful in a short period of time.
All of this became top secret in each civilization, known only to a very few people. These people were originally the top scientists of each civilization, under strict protection. Now that they were conducting secret research, even fewer people knew about it. And not all of these civilizations trusted Li Shun.
Conversely, a small number of civilizations were relatively clear about Li Shun's actions, but the allure of the technology tree was too great. Moreover, obtaining the technology tree did not require any action; all that was needed was to keep it secret and not interfere with Li Shun. No civilization could refuse such a good deal.
The alliance returned to calm, but Hu Yu became even more depressed. The situation in the galaxy was in chaos, and no matter which way he went, it felt wrong. He was like a starving drifter in the deep sea, desperately thirsty. He couldn't drink the seawater, nor could he not drink it. But if he didn't drink, he would die immediately, while drinking it might give him an extra hour of life. He had no choice but to drink a little.
There's also the power behind the Fish Horse Star Civilization, which has remained completely silent for so many years. The quieter it is, the more uneasy Hu Yu feels. This unusual silence is almost suffocating, but Hu Yu can do nothing but develop the fleet and knows nothing about anything, leading to a deep sense of powerlessness.
Two thousand years have passed since the Battle of the Defense Line. A piece of news about a technological breakthrough finally made Hu Yu happy. Academician Zhou Xiaohua has finally solved the problem of locating the coordinates of the three-dimensional universe in the fourth dimension. From now on, there will be no need to rely on coordinate base stations for operations. However, precise positioning can only be carried out in the Milky Way.
Academician Zhou began researching this problem at the Star-Level level and it took him 80,000 years of painstaking research to solve it. In addition to admiring Academician Zhou's extraordinary wisdom, we should also admire his perseverance and indomitable scientific research spirit.
Three-dimensional space is hidden within four-dimensional space. Entering four-dimensional space from three-dimensional space requires not only technological methods but also high energy. Four-dimensional space is a high-energy space. Upon arriving in four-dimensional space, you will find that three-dimensional space has disappeared, and the warship is in another high-dimensional space. Returning from this high-energy space to a low-energy space is simple; you only need to lower the warship's energy level, and it will be automatically expelled by the high-energy four-dimensional space.
Because high-energy spaces do not allow low-energy objects to exist, just like a bird flying in the sky. If the bird lowers its energy and stops flapping its wings, it will immediately fall down. Therefore, in the fourth dimension, whether it is a warship or an insect, they are all high-energy. Even low-level insects are high-energy because the energy density of the Chong Element is almost higher than that of a warship.
Because of the extra dimension, four-dimensional space can arbitrarily abandon one dimension to allow low-energy objects to enter another three-dimensional space. If the coordinates in three-dimensional space are ABC, and in four-dimensional space they are ABCD, then returning from four-dimensional space to three-dimensional space could result in ABC, or it could be ACD, ABD, or BCD. Except for ABC, warships will get lost when entering other spaces. Even if they enter ABC, they can only randomly land in some three-dimensional space when their exact location cannot be determined.
Therefore, the warship must find the connection between the three-dimensional universe and the four-dimensional space to lower its energy level before it can return. However, finding this connection is extremely difficult. It is easy to find a high-energy place in a low-energy space, but it is difficult to find a low-energy place in a high-energy space.
However, Academician Zhou Academician Zhou overcame all difficulties and eventually discovered the spatial frequency, or rather, the spatial frequency of the entire three-dimensional universe. The three-dimensional universe is expanding and operating, and a powerful yet faint fluctuation has appeared in the entire space. It is powerful because this fluctuation is present throughout the entire universe and no force can stop it, but it is also very faint, so faint that it would not have been possible to detect its existence if it were not for the advancement of space technology.
