After so many years of separation, it's impossible for them to feel as if they'd only been apart for a few minutes, or as if no separation had ever happened at all. It's as if some of their memories had been erased, or as if some non-existent memories had been added to them, making them feel like they had never been apart.
However, this was not the case among the fleet's high-ranking officers and academicians. Although they did not show any joy or surprise at the long-awaited reunion, Hu Yu could tell from their feigned indifference that they were also puzzled by the situation. These people were all very perceptive and knew what the current situation was.
Hu Yu directed the fleet through the spatial fragments, turning left and right. Just as the fleet's energy was about to run out, a huge spatial fragment appeared. This fragment was 0.1 light-years in size, and within it, there was even a remnant of a celestial body the size of Jupiter.
Moreover, there was still some energy in this fragment. Approaching the stellar debris, Hu Yu immediately realized that a dangerous entity might be nearby. The fact that the Ancestor had mentioned the super- Great Star Region Civilization civilization that had broken into the Mirror Sub-Universe was true; otherwise, the Ancestor would not have made such an arrangement.
All of this was orchestrated by the Ancestor to conceal his own existence. Humanity's development in the Mirror Sub-Universe was due to the fortunate discovery of a large spatial fragment containing celestial bodies, energy, and the advantage of time, which naturally enabled the creation of a fleet.
Although this celestial body is so small, even if that Galaxy Civilization were to intrude now, it would be impossible to determine whether there was originally only one celestial body here, or the remnants of multiple celestial bodies.
Hu Yu felt a chill run down his spine. Just how powerful was this Galactic-Level Civilization that even the omnipotent Zudu in the Mirror Sub-Universe was so afraid of it? If this Galactic-Level Civilization were to attack him, he might not even have the courage to resist. However, for the time being, this Galactic-Level Civilization had not yet shown itself for some reason.
But the more lurking in the shadows, the more terrifying it is. Especially since this civilization has already surpassed all other civilizations in the galaxy. It's no longer a venomous snake hiding in the grass, but a giant python lurking in the shadows, with its mouth wide open, ready to swallow Hu Yu whole at any moment.
Hu Yu suppressed the chill and immediately summoned the academicians to discuss establishing a stable spatial channel in the spatial fragments. The space originally provided by the ancestor no longer existed or could not be found. Even if it existed, it would not be enough for so many civilizations. In the future, there might be a dozen or even dozens of civilizations that would need to build fleets in the Mirror Sub-Universe.
Only with a sufficient fleet can we fight against the Insect Race, the Fish Horse Star Civilization, and even the Andromeda Civilization. The Mirror Sub-Universe is the lifeblood of the galaxy, but creating a spatial passage through the space debris is as difficult as building a highway on a cliff, so difficult that even Great Star Region Advanced Civilization cannot do it.
Because there is a lack of space here, and more of Void, while the technological systems of all civilizations in the galaxy are based on space. Just like fish out of water, even a great white shark can't jump around much. Only in the water can sharks reign supreme and dominate.
Human technology is also based on space, but humans have already understood the nature of space. Hu Yu believes that the academicians may have a way to build a space highway here. As long as the fleet can perform warp drive here, it can take advantage of the time advantage.
Academician Zeng stated that to build a space passage here, the first step is to eliminate this Void, because this Void is the most energy-consuming factor in fleet navigation. Most of the warship's energy is used to combat this Void. Moreover, the warships of the Small Star Sector Civilization are simply unable to navigate in this space debris and are easily torn to pieces by it. This is why Hu Yu wants to place the Carina Civilization in the three-dimensional universe, because their fleet cannot withstand the tearing effect of this space debris.
Academician Zeng has been studying this kind of Void since the first antimatter star explosion. However, since this kind of Void only exists in certain special cases in the three-dimensional universe, Academician Zeng's research has not made much progress. In addition, the fleet has many other research tasks, so Academician Zeng has not had time to come to the Mirror Sub-Universe to conduct specific research.
Over the past tens of thousands of years, Academician Zeng has spent a great deal of time studying this Void. Academician Zeng believes that this may be a kind of Anti-Space, or Virtual Space. This space is the opposite of normal space based on a certain dimension. Positive and negative numbers are opposite based on the Y-axis, so Positive Space and Anti-Space can only be opposite based on a certain dimension.
An explosion with immense power and energy might twist space in another dimension, creating Anti-Space. This dimension is not the fourth dimension; Academician Zeng has not reached a conclusion as to which dimension it is, as it is merely a conjecture.
The greatest impact of spatial collapse occurs at the edge of the collapse, where dimensions and space may be twisted, to the point that even the Fish Horse Star Civilization could not withstand it. However, the Void after the collapse is not so terrifying; the Fourth Reversed State can already withstand it.
There is also such Void between the Basic Space that form Basic Energy, and the amount of this Void is greater than that of the Basic Space. Academician Zeng speculated that perhaps our Positive Space universe is just a low-probability event, and the real Anti-Space is a more advanced and vast universe.
Building spatial channels requires filling these Void spaces. The fleet currently lacks the method to manipulate Basic Space on a macro scale. Even if it did, repairing this space spanning thousands of light-years would be unrealistic. To achieve this, we must start from other aspects.
Unlike the larger universe, where space is disrupted, cut, or distorted, these spatial fragments do not quickly return to normal once the external force disappears. This is largely due to the macroscopic spatial force of the larger universe. The Mirror Sub-Universe is very small, and its macroscopic spatial force is also very weak. It was still manageable in the space where Zu lived, but in these peripheral areas, the spatial force is so weak that it can be ignored.
If the macrocosm is a vast ocean, then the Mirror Sub-Universe is a small puddle on the ocean's shore. These spatial fragments are the gaps between the sands connecting the small puddle and the macrocosm. The reason why there are so many Void in the connecting zones of the Mirror Sub-Universe is very likely because this connection between the mirror space and the macrocosm has been twisted, twisted in another dimension.
