This is just the simplest form of cryptography. Some cryptography has multiple keys, and each key has a completely different meaning. However, Academician Liu made it so simple, and there is a reason for that. First of all, only the Chinese Nation can understand this key. Even if other people get the key, they will not know the meaning of these symbols. Moreover, the key itself is a set of cryptography. The real key needs to be deciphered from the key to understand the true meaning contained in this book on multidimensional space geometry.
"Academician, General, everything I've seen, encountered, and thought about is contained in this book on multidimensional space geometry. You must not reveal a single word of this content. Of course, once you've read it, you'll understand its importance without me having to remind you."
"Alright, but Academician Liu, you'll have to make do for now and continue living in anonymity on the Tree Race planet."
"Feeling wronged? Haha, not at all. I've never been this comfortable. No need for research, no need for work, I can see beautiful and wondrous sights every day, and when I'm tired, I can lie down anywhere. When I'm thirsty or hungry, there are delicious fruits everywhere. Now that my wife has come, she cooks me a few dishes every day, and my Tree Race friends and I often have a drink together. I can't imagine how wonderful my life is."
"We will pick you up as soon as possible," Hu Yu said solemnly.
Although Academician Liu Bo said that, Hu Yu and Academician Zeng both knew that what he really wanted was to return to the fleet to do research. However, the current situation was too special. If Academician Liu appeared on the fleet and was recognized by the four-dimensional spy, then there would be big trouble. If that being that Lord Zu feared knew that humans had a connection with the Ancestor, then humans might be wiped out of the universe in an instant.
"General, General Chen Peng is on another inconspicuous planet. If you want to go, have my Tree Race friend take you there; that way you won't be too conspicuous."
"We won't go for now. Ask your Tree Race friends to tell them that you'll all be able to return to the fleet soon."
"Okay, you guys should go out first. You've been here long enough; you don't want to attract attention."
The Tree Race celebration lasted for a full month, and Hu Yu could only stay there for that entire month. After a month, Hu Yu, Academician Zeng, and the leaders of other civilizations returned to their base. The others, still wanting more, stayed on the Tree Race planet, as the leaders had to go back to handle various matters.
Academician Zeng returned to Earth Two, while Hu Yu returned to Earth Four. Both of them began reading the book on multidimensional space geometry. What they found was quite shocking; Hu Yu broke out in a cold sweat after reading it. Hu Yu didn't understand the scientific parts, but the part about Lord Zu made Hu Yu shudder.
Which civilization in the Milky Way was Zu? And which civilization went to find Zu and even fabricated a huge lie to lure these Small Star Sector Civilization into searching for Zu's traces? It's clear that this civilization was very interested in Zu, although for Zu, this interest was not a good thing.
There was nothing wrong with Academician Zeng, since Academician Zeng had met Zu and knew about Zu's affairs. However, Academician Liu's research on the Universe Membrane was indeed very fruitful.
Within the Universe Membrane, Academician Liu observed the existence of two-dimensional space. Although the Mirror Sub-Universe exists in 3.5 dimensions, it is still a three-dimensional space. The macrocosm is also a three-dimensional space, with a layer of two-dimensional space sandwiched between the two three-dimensional spaces. This explains why directions in three-dimensional space are mirrored in the Mirror Sub-Universe.
Academician Liu believes that this is all the result of two-dimensional space. At first, Academician Liu only knew that it was Mirror Sub-Universe, but he had no idea why it was mirrored or why it produced a mirror effect. Logically speaking, when entering another three-dimensional space from one three-dimensional space, regardless of whether the direction is reversed, a person's left and right consciousness will not be reversed.
It was only after the discovery of the existence of two-dimensional space in the Universe Membrane that Academician Liu was able to solve this problem. Here, the two-dimensional space unexpectedly formed an incomplete Möbius strip-like structure under the relative rotation of the two universes. When the fleet sailed around this incomplete Möbius strip, its left and right sides would unconsciously switch.
Logically, three-dimensional beings walking on a Möbius strip should not have their left and right sides reversed. However, the warship was unconsciously turned into a two-dimensional entity after entering this two-dimensional space. Academician Liu also gave a detailed explanation as to why the warship was turned into a two-dimensional entity without any dimensional reduction.
The first thing involved is the Basic Space Force. Dimensional reduction is actually a process of force balance. When the force of the Four-Dimensional Basic Space is less than that of the three-dimensional space, the extra dimension will be reduced. When the force of the Four-Dimensional Basic Space is greater than that of the Basic Space Force, the phenomenon of dimensional reduction will not occur.
The two-dimensional space of the Universe Membrane is very small, and its spatial power is far less than that of the three-dimensional Reaper warship. Therefore, the warship did not exhibit dimensional reduction but was instead enveloped by two-dimensional space. Its exterior was two-dimensional, but its interior remained three-dimensional. This is similar to the hypersphere, which uses the energy of three-dimensional space to envelop four-dimensional space. From the perspective of the three-dimensional universe, the hypersphere is just an ordinary three-dimensional sphere, but in reality, it is a four-dimensional structure.
The same applies to two-dimensional space enveloping three-dimensional space. From the outside, the warship appears to be two-dimensional, but inside it remains a three-dimensional structure. The hypersphere undergoes dimensional reduction because the outside is the vast universe with exceptionally powerful spatial forces. However, the three-dimensional warship is not dimensionally reduced when enveloped in two-dimensional space because the outside is only a small two-dimensional space.
Academician Liu not only discovered the existence of two-dimensional space, but also discovered Two-Dimensional Basic Space. According to Academician Liu's Basic Space Theory, different types of Basic Space form different spatial structures. Two-Dimensional Basic Space, Three-Dimensional Basic Space form three-dimensional space, Four-Dimensional Basic Space form four-dimensional space.
However, Academician Liu did not offer any conjectures regarding spaces beyond four dimensions. Although the existing mathematical models are quite mature, Academician Liu always felt that there were significant differences between them and real space.
The discovery of the Two-Dimensional Basic Space was also accidental. Academician Liu originally thought that the Basic Space was a hundred orders of magnitude smaller than the Basic Energy. However, at the Universe Membrane, Academician Liu discovered the atomic-level Basic Space. This discovery excited Academician Liu greatly. However, this giant version of the Two-Dimensional Basic Space is very rare. Academician Liu only extracted a limited number of pieces. If enough Basic Two-Dimensional Space could be extracted and laid on the surface of the warship, even without Wen Zhonghua going to guide them, Academician Liu and his team could return to the base unnoticed.
