Xiao Yu was still moving forward rapidly, towards the very core of this river system.

There, is the heart of this vast river system. Because of the tendency of matter to fall towards the core, the density of matter there is the highest in the entire river system. This means that there will be enough interstellar dust there, and enough star dust will mean that new stars will be born there. Young stars are not calm, and their stellar activity can be extremely intense, which is also not suitable for the emergence and development of life. However, as time passes, as these stars age, they tend to level off. And the stellar radiation brought by their stellar activities will also open up a world of their own in the space full of interstellar radiation, and intelligent beings may thrive here.

In addition to exploring different river systems, it is also important to communicate with various intelligent beings. It doesn't matter if these intelligent beings are advanced or low. At this moment, Xiao Yu is looking for the intelligent civilization that may exist in the river system IC1101.

Therefore, the advance speed of Xiao Yu's fleet is not too fast-compared to the 3,000 times the speed of light that Xiao Yu already has at this moment, and the forward speed of 1,200 times the speed of light, it is undoubtedly very slow. Even so, Xiao Yu also stopped and stopped all the way, and from time to time took some detour routes to go to some places that he was more interested in for field exploration.

In this process, a large number of probes were also launched by Xiao Yu. Xiao Yu's fleet is like a powerful seeding machine, which has passed thousands of years since it entered the river system IC1101. Hundreds of billions of trillions of probes were launched by Xiao Yu. These probes brought a lot of data that Xiao Yu was very interested in.

At this moment, tens of thousands of years have passed since Xiao Yu left the Shenzhou and Pegasus civilizations. During this time, Xiao Yu's technology has once again made great progress. The main reason for this level of progress is that there has been. It is the observation data from the inside of those black holes of the Shenzhou and Pegasus civilizations. These materials once again pointed out a broad way forward for Xiao Yu, who had basically fallen into a bottleneck.

Xiao Yu has even faintly touched the existence of the rules, and has some understanding of the most high-end and mysterious power system in this universe. This means that Xiao Yu has become the pinnacle of the seventh-level civilization, and he only needs one opportunity. With just one opportunity, Xiao Yu can fully grasp the rules and become an eighth-level civilization.

And thanks to Xiao Yu's own characteristics. After becoming an eighth-level civilization, Xiao Yu will inevitably be the most powerful eighth-level civilization. Because Xiao Yu has almost endless computing power, these computing power can allow Xiao Yu to build the most complete and impeccable rule system. Xiao Yu can have the advantages of cosmic civilization at the same time. It is also possible to have some of the advantages of other types of civilizations.

Xiao Yu is not any civilization that develops in a single direction. Xiao Yu is not a traveler civilization. It is not a cosmic civilization, not a macroscopic civilization, not a musical civilization, Xiao Yu does not belong to any type, Xiao Yu is a comprehensive civilization that condenses the advantages of all these types of civilizations.

"Maybe it's because my accumulation is still insufficient, and I have never been able to truly become an eighth-level civilization." Xiao Yu sighed secretly, "The rules are just like that, but I can't find a way to master them. ”

Xiao Yu thinks. The so-called rules are not actually an innate attribute of matter. For example, water. Freezing at zero degrees Celsius and boiling at 100 degrees Celsius at standard atmospheric pressure is not something that water is born with, but because of the influence and restraint of other forces. Similarly, light travels at a speed of 300,000 kilometers per second, and the speed of light remains the same no matter where it is observed.

Rules are such a magical force. It is omnipresent, it holds all the properties and forms of matter. Any movement, any reaction, is under the control of the rules. It is not ethereal, Xiao Yu believes that rules are also a kind of power, and it is this power, or energy, that controls everything he sees and learns.

It requires that the water must freeze at zero degrees Celsius and must boil at 100 degrees Celsius, so the water freezes at zero degrees Celsius and boils at 100 degrees Celsius. It requires that the light must be at this speed, so the light is always 300,000 kilometers per second.

This is an unknown existence in the outside world - Xiao Yu calls this unknown existence the rule-maker. Xiao Yu didn't know who the rule-maker was, it could be the universe itself, or it could be the defender, it didn't matter who it was, the important thing was that the rule-maker formulated this series of rules, stipulating the so-called physical properties that various substances in the universe must have.

Becoming an eighth-level civilization and mastering the rules will master the ability of a rule-maker to a certain extent. Level 8 civilizations can change the rules set by the rule-makers on a small scale, and re-formulate the rules according to their own hearts to give matter different physical properties. This is the ability that an eighth-level civilization can have.

It was only after he initially grasped the mystery of the rules that Xiao Yu knew why after he detonated the entire river system, there would be a temporary out-of-control phenomenon within the explosion range. Because rules are also a kind of power, and the energy of the explosion of the entire river system is too violent, and this energy washes away the regular power that binds matter.

At the same time, for the rest of the three-dimensional space that is meaningless, Xiao Yu also has some preliminary understanding. The reason why those rest of the universe is meaningless is because there are no rules within them. No rules mean that anything can happen, and since anything can happen, nothing makes sense. And the reason why there are no rules in these cosmic spaces, Xiao Yu guesses, is probably because there is no rule-maker who makes rules for them.

Does this mean that the three-dimensional universe in which you live also has no rules in the initial stage? Xiao Yu can't find the answer to this question for the time being. At this moment, there is another problem plaguing Xiao Yu.

The question is, if the difference between the rest of the universe and the three-dimensional universe in which it is located is only that it has rules and does not have rules, then what is so special about the universe in which it lives? If you become an eighth-level civilization and go to another universe by yourself, make rules for that universe, and let it develop according to the laws, then can the other universe also develop like the current universe?

"So, the universe I'm in is just an ordinary one of countless universes?" Xiao Yu muttered to himself, trying to think about this question. This conclusion made Xiao Yu feel very awkward in his heart, and Xiao Yu was very reluctant to accept it, but Xiao Yu couldn't find a reason to refute and overturn this conclusion.

"When I have the opportunity in the future, let's explore it in detail." Xiao Yu sighed and put the question aside for the time being.

At this moment, Xiao Yu's mood is like that of a medieval European. Medieval Europeans stubbornly believed that the earth was the center of the universe and showed a strong rejection of heliocentrism, although all kinds of observations have shown that the earth is just an ordinary planet, but people just can't accept it.

It's easy to understand – who wouldn't want to be from a special background? Who wants to accept that the earth, which has survived all their lives and is known as a god, is just an ordinary guy? If the earth is just an ordinary guy, then what are the human beings who depend on the earth to survive?

Xiao Yu is also in this mood at the moment. Living in this universe, Xiao Yu also wants this universe to be unique. If this universe is just an ordinary one of countless universes, it would be a little too miserable.

Unable to figure it out, he put this issue aside for the time being, and Xiao Yu continued to do his own thing. Up to now, Xiao Yu has penetrated hundreds of thousands of light-years into the river system IC1101, but compared to the huge span of the river system IC1101, this distance is still nothing. During the voyage of hundreds of thousands of light years, Xiao Yu personally visited countless stars, and Xiao Yu's probe advanced several times farther than Xiao Yu, and visited dozens of times more stars than Xiao Yu, but Xiao Yu did not find any signs of intelligent life.

This proves at least half of Xiao Yu's inference that life is unlikely to exist on the periphery of IC1101 in the river system. As for whether there is life in the core of IC1101 in the river system, further exploration is needed to know.

Under this dark red cosmic background, Xiao Yu's huge fleet continued to move forward.

Suddenly, a detector reported a piece of information that interested Xiao Yu. With the arrival of this message, another picture message also reached Xiao Yu's mind. Xiao Yu's spirit was shocked, and he immediately gave the probe an order for detailed detection. At the same time, a fleet of about 10,000 spaceships left Xiao Yu's large army and sailed towards this place.

This fleet carries enough detection instruments, and Xiao Yu believes that this fleet also has enough defense forces. This fleet is enough to dig up all the secrets hidden there.

"A crashed alien ship?" Xiao Yu thought with interest. (To be continued......)
