Xiao Yu is sure that even under different universes and different rule systems, the development of science and technology should have some commonality. When it comes to technology, the most important thing is energy.

In fact, looking at the scientific and technological development process of Xiao Yu or some other civilization, we can find that the progress of science and technology can also be regarded as a process of continuous updating and efficient energy acquisition. From burning firewood for energy, to burning fossils, such as coal or oil, to relying on nuclear energy and elemental decay to obtain energy, until now, space has been used directly as an energy source.

The more efficiently energy is obtained, the higher the level of technology.

In the face of Xiao Yu's super computing power and logical ability, Xiao Yu quickly found the primary energy acquisition method of this universe that was completely different from the previous universe, and Xiao Yu found the "firewood" in this universe, which is the easiest way to obtain energy in this universe.

Very unexpectedly, the "firewood" in this universe turned out to be a method similar to nuclear fusion in the original three-dimensional universe. Nuclear fusion is very convenient and safe in this universe, and it is also one of the least efficient ways to obtain energy.

With this way of obtaining energy, Xiao Yu finally gained the ability to further explore this universe. After receiving that piece of information and knowing that music civilization was protecting him, Xiao Yu completely stopped worrying about his safety. Although Xiao Yu still has a lot of questions in his heart - because it is a very strange thing for the music civilization to know that he will come here and wait here in advance, and. Xiao Yu still didn't know anything about what the so-called rebel's universe was, but none of these things were important in comparison. The most important thing is that Xiao Yu must find a way to survive independently in this universe in the shortest possible time.

Xiao Yu had already considered the grim environment he might face after entering another universe, but to be honest, the grim environment was so severe that Xiao Yu really didn't expect it at this moment.

"Fortunately, there is a musical civilization that protects me." Xiao Yu thought silently.

Xiao Yu put all his energy into the development of science and technology. Compared to Xiao Yu's computing power at the moment, some of the more rudimentary technologies really don't take long to fully master. As the level of civilization increases, information will explode. Correspondingly, along with the reduction of the level of civilization, there will also be an explosive decrease in information. So. In less than a month, Xiao Yu has passed through the primitive society in this universe, almost entered the scientific and technological process equivalent to the feudal era in the three-dimensional universe, and is no longer far away from the industrial revolution.

The interior of Xiao Yu's spaceship and the space occupied by the spacecraft still maintain the rule system in the three-dimensional universe. Xiao Yu began to study the technology of another universe in such a rule system.

There are already some simple ones. Machines that conform to the rules of the universe were created, and at the same time, basic sciences such as optics and mechanics made great progress. Xiao Yu finally built the first telescope and opened the first window to this universe.

Next to the space occupied by Xiao Yu's fleet, in the strange space that adheres to the rules of the universe, Xiao Yu built his first observatory. Of course, because Xiao Yu has not yet mastered the radio of this universe. At this moment, Xiao Yu can only obtain the observation data of the observatory through extremely complex means.

Xiao Yu cast a curious glance at this universe for the first time. What was presented in front of Xiao Yu was a bizarre scene. Indescribably bizarre scene. Xiao Yu saw the stars in this universe, and saw the stars, planets and dust in this universe.

It may not be a star, because of the dominance of the unique rules of this universe, the stars that Xiao Yu saw, although huge, are obviously not obtained through nuclear fusion, which is a way of obtaining energy that Xiao Yu has not yet understood. Thinking about it, in the original three-dimensional universe, when a civilization has only just mastered chemical energy, it is impossible to know what stars rely on to obtain energy.

What makes Xiao Yu even more strange is that the law of gravity in this universe seems to be completely different from that in the big universe. Although smaller stars still orbit larger stars, their orbits are not elliptical, but three-dimensional, more complex.

After the development of science and technology reaches a certain stage, it is inevitable to look into the universe. Just as Newton finally came up with the law of gravitation. The initial development of science and technology is a summary and induction of natural phenomena, and Xiao Yu has embarked on the same path at this moment. Xiao Yu tries to find out the mystery behind this strange orbit.

That's why Xiao Yu couldn't wait to build the observatory. If you want to discover more patterns, you have to broaden your horizons, and if you want to broaden your horizons, the observatory is the only way.

This observatory provided Xiao Yu with a large amount of observational data. At the same time, a large number of realities, physics, chemistry, engineering mechanics, materials science, and so on are also being carried out simultaneously. The laws of physics can be summarized by the observation society, and the laws of physics can in turn promote the development of the real laws in a better and more standardized way. Xiao Yu embarked on a virtuous circle in this way.

In the midst of these thousands of realities, as if on earth, Xiao Yu discovered a by-product in a casual mistake. This by-product is somewhat similar to radio waves in a three-dimensional universe that can travel at extremely high speeds. Xiao Yu was very interested, so he immediately started research on this kind of radio wave, and finally succeeded in developing a communication device based on this radio wave.

As a result, Xiao Yu's efficiency has been greatly improved. This means that Xiao Yu can directly control the real equipment and detection instruments he has arranged in the distance through this kind of radio wave, and no longer has to use the extremely troublesome method before. Xiao Yu can also use this radio wave to create a more advanced device, a radio telescope, to receive all kinds of radiation in the universe that cannot be seen or touched, but carries more information.

The discovery of this radio wave and subsequent research also brought another benefit to Xiao Yu. That is, Xiao Yu can finally connect with the music civilization that has been protecting him.

In addition to the complicated realism and calculation, Xiao Yu used this radio wave to make his first voice after coming to this universe.

"Musical civilization, thank you. Can you tell me where the hell this is, and why your civilization would know that I ended up here? Xiao Yu asked.

Xiao Yu soon received a reply.

"This is the Rebel's Universe." Musical civilization repeats the word, and then says, "This qiē stems from a delicate and vast plan." The spokesperson had already known the plans of the four eighth-level civilizations, so he arranged for me to come here to meet you in advance. And then with the help of you, calculate the rebel alliance. I hope you can understand the painstaking efforts of the spokesperson, and don't hold a grudge just because you became a pawn of the spokesperson in this plan. You know, this plan is good for you too. And, you don't have to pay much to get these benefits. ”

"Chess pieces?" Xiao Yu responded with a wry smile, "It seems that since I left the earth, I have always been a chess piece, and I don't care about being like this again." What's more, spokesperson, no, Chen Mo must have no ill will towards me. It's just that I don't understand, why didn't you sue me in the original universe, and you didn't sue me until now? ”

"Because suing you is tantamount to suing the defender, and this plan cannot be known to the defender in advance." The musical civilization was silent for a moment, and replied, "The Defenders are almost omniscient and omnipotent, and in order to resist the prying eyes of the Defenders, both the Spokesperson camp and the rebel camp have established their own bases in the outer universe. Because only by leaving the three-dimensional universe can we avoid the eyes of the defenders. This is the base established by the rebel camp, referred to as the rebel universe. ”

"The defenders are watching you, and you have come to the rebel universe, which means that the eyes of the defenders have also come to the rebel universe. The rebels are also enemies of the Defenders, and the spokesperson uses this plan to expose the Rebels' base information in front of the Defenders, so as to achieve the goal of weakening the Rebels. That's the whole process of planning. ”

"I see." Xiao Yu said, "So...... What about you? Is my current contact with you also in the eyes of the defenders? ”

"No, not now." "The barriers between the different universes are too strong for even the Guardians to break through in a short period of time. So now you are completely free. But this freedom lasted less than a year. After about eight months, I'll cut off contact with you to avoid the prying eyes of the defenders. That is, you only have eight months to develop safely. ”

"And...... There is another purpose for you to come to the Rebel universe. "After all, the rules in the Rebel universe are simpler and easier to change than the rules in the three-dimensional universe. This also means that it is easier to become an eighth-level civilization in the rebel universe than in the three-dimensional universe. You, Xiao Yu, step into the realm of the eighth-level civilization in this rebel universe......" (To be continued......
