" Demon Scorpion, as soon as possible, determine the location of the Fish Horse Star Civilization's main base. Remember, you must confirm the true main base of the Fish Horse Star Civilization. Don't let it turn out to be just another branch base," said the Yun San Civilization.
"We'll figure it out ourselves without you reminding us."
"Everyone, prepare yourselves and find a way to completely destroy the Fish Horse Star Civilization."
Hu Yu returned to the base. The Conqueror had almost been wiped out. After 2000 years of accumulation in the Secondary Universe, plus what Hu Yu brought back, the total was just over two trillion. This was only because Wen Zhonghua had taken back the original base. With the addition of the base in the Secondary Universe, the speed at which humanity built ships had reached 600 million ships per year with the assistance of Superintelligent Robot. Fortunately, in recent years, the fight against the Fish Horse Star Civilization had been entirely thanks to the Yun San Civilization; otherwise, Human Civilization's warships would have been even fewer.
However, building a base is extremely difficult. Even with current human technology, it would be difficult to rebuild a base in less than 10,000 years. Although the Conqueror warships are mostly produced by injection molding, the production lines needed for areas that cannot be produced by injection molding are still unimaginably large.
Without the assistance of Superintelligent Robot, humanity could at most maintain the operation of one base. Population has always been an important factor in the development of civilization. It is conceivable that if the Andromeda Civilization hadn't frequently cleaned up the Milky Way, the populations of these Great Star Region Civilization would have long since spread throughout the galaxy.
With the threat of the Andromeda Civilization and the invasion of the Insect Race, the five Great Star Region Civilization in the Milky Way have been struggling to cope and can only eke out a living in the Alliance Space. If it weren't for the intervention of that Galactic-Level Civilization, these major Great Star Region Civilization might have remained hidden in their own small spaces forever.
Deep within the Secondary Universe, Hu Yu met the busy academicians who were making full use of the time advantage of the Mirror Sub-Universe to improve the fleet's technological level. The Conqueror produced in recent years have the ability to fight in the fourth dimension and no longer rely solely on the off-target attack method of two-dimensional bombs.
Moreover, with the technological support provided by Yan Xue, their travel speed has reached more than 10,000 times the speed of light. In terms of speed, the Conqueror are no less Great Star Region Advanced Civilization. However, their ability to fight in four dimensions is still slightly inferior to that of the Yun San Civilization.
A common tactic in four-dimensional warfare is to manipulate energy in the fourth dimension, alternating between four and three dimensions to gain control of the battlefield. Fleets can now do this. Moreover, in recent years, academicians have conducted meticulous analysis and research on the attack methods they have seen in the fourth dimension, and selected two attack methods that are most suitable for human technology.
One method is Space Decomposition, which Space Decomposition into a collection of multiple three-dimensional spaces. This Space Decomposition is used to tear apart the enemy fleet. This is an attack method that Hu Yu saw used by a Insect King in the fourth dimension, and the academicians immediately took a liking to this attack method.
Previously, it was merely something to admire, but the fleet's technological means could not achieve it. Since the discovery of the Basic Space, all of this has become possible. In particular, Academician Liu has gone out of the Mirror Sub-Universe many times in order to study the Basic Space structure of the fourth dimension. However, Academician Liu did not discover the Four-Dimensional Basic Space in the fourth dimension. The Basic Space there is still three-dimensional. The four-dimensional space is formed by various combinations of Three-Dimensional Basic Space space.
Although it deviated somewhat from Academician Liu's assumptions, Academician Liu had already guessed this possibility. After discovering the essence of four-dimensional space, Space Decomposition was almost a piece of cake for humans who had mastered the Basic Space. After tens of thousands of years of effort in the Mirror Sub-Universe, the problem of Space Decomposition was finally solved.
Humans can now decompose fourth-dimensional space, just like that Insect King did back then. The Space Decomposition attack developed by Academician Liu is launched from the lowest level of space. No matter how powerful the enemy's warship is, it is difficult to withstand this attack. It's like a tank that is powerful, but you are holding a wrench and twisting it inside the tank.
Since the Basic Space is a three-dimensional structure, all Space Decomposition cannot further decompose the three-dimensional space into two-dimensional space. However, the Three-Dimensional Basic Space can still be changed into two-dimensional space. Currently, the dimensional reduction attack of the fleet's two-dimensional fragments has limited effectiveness and is barely enough to deal with the Fish Horse Star warships. More often, surprise attacks are needed to achieve combat results. Once the Fish Horse Star Civilization has made defensive preparations, the two-dimensional fragments will be difficult to play a role.
Another attack method for operating in the fourth dimension is also based on Basic Space Theory: Space Banishment. Four-dimensional space can contain three dimensions. Warships can still move normally in the three-dimensional space within four-dimensional space. Only when the warship needs to return to the three-dimensional universe can it reduce its energy level and find a point of convergence to return to the three-dimensional universe normally.
However, if the warship fails to find a point of convergence after lowering its energy level, it may not return to our three-dimensional universe. The fourth dimension is XYZS, the three-dimensional universe is XYZ, and the warship may return to XYS, ZYS, or even a completely new ABC space.
There is no way to study these spaces, and no civilization has ever been seen in them. No warship that has ever been lost in these spaces has ever returned. Civilizations capable of operating in the fourth dimension almost universally believe that these spaces are either meaningless or have a completely different physical system from the three-dimensional universe. Once a warship enters these spaces, it will collapse due to the difference in physical system.
The fact that physical systems are different is a terrifying thing, and its effects are even more terrifying than changing the rules. In the three-dimensional universe, changing the rules can only make appropriate changes to the existing rules in certain aspects. For example, the speed of light is 300,000 kilometers per second. Changing the rules might allow the speed of light to reach 400,000 kilometers per second, but whether light even exists in a space with a different physical system is a question.
The Space Banishment attack developed by the academicians based on Basic Space forces involves exiling enemy warships into these unfamiliar spaces, altering spatial forces, and allowing the warships to be directly exiled in a high-energy state. This move is even more terrifying than Space Decomposition.
However, neither Space Decomposition nor Space Banishment can be done at will by the Conqueror. All of this requires gaining control of space, which either means possessing more and higher-level energy or directly controlling the spatial power of the battlefield.
Given humanity's current situation, gaining control of space remains somewhat difficult. Being able to conduct space warfare in the fourth dimension signifies that humanity has officially entered the Great Star Region Intermediate Civilization. However, compared to those Great Star Region Advanced Civilization, humanity still lags behind in both the level of energy it possesses and the power of space.
