When he saw that thing for the first time, Xiao Yu's heart was quite shocked, Xiao Yu almost thought that it was the architectural civilization he had encountered in the three-dimensional universe and had also come here. If it weren't for an architectural civilization, what other type of civilization would have built such a huge, so beautiful, so magnificent that it is impossible to describe in words?

At this moment, what Xiao Yu saw was such a thing. It was a castle, a very, very large castle. Just based on some of the primary information that Xiao Yu had obtained at the moment, Xiao Yu calculated that the longest part of this castle, which was probably irregularly shaped, was ...... It is more than a hundred light-years long, and almost fifty light-years at its top. This castle occupies at least 200,000 cubic light-years of space.

A wordless shock spread in Xiao Yu's heart. Xiao Yu almost immediately denied that this was built by the architectural civilization. The reason is very simple, not to mention a building civilization, even if it is ten, a hundred building civilizations cannot build such a great building, even Xiao Yu, who has become a seventh-level peak civilization in the three-dimensional universe, is already the most powerful under the eighth-level civilization, and Xiao Yu, who has infinite computing power, has no ability to build such a building.

"To build a building of this magnitude...... It seems that turning the entire galaxy into building materials is not enough...... The Flying Kite Galaxy may be enough, but it's not sufficient......," Xiao Yu muttered.

A skyscraper may be tens of thousands of times the size of a wooden house, but it is much more difficult to build than tens of thousands of times. There is a very simple reason that as the volume of the building increases. The difficulty factor does not increase exponentially, but in a straight line. This means that the volume of this building may only be tens of thousands of times that of the building civilization. However, the difficulty of construction is tens of millions of times higher than that of building civilization, or even hundreds of millions of times.

This is a great building that even Xiao Yu dare not imagine.

With subsequent observations, Xiao Yu discovered more details about the building. Xiao Yu saw that there were countless stars surrounding this great building, like gems of different colors, the yellow ones were like topazes, and the blue ones were like sapphires. The black hole is a black gem, and these countless gems are dotted next to this building, making this building even more sacred. Meanwhile. There is also a large amount of cosmic dust, stardust gathered next to this building, and they are like a mist covering the mountain peaks, which sets off the building even more unreal......

There's even a river made of stars. In the middle of this river there are about the number of stars in the Milky Way. They are so closely packed that they are only a few thousand light-years long, but the dense arrangement of stars makes it even more dazzling and dazzling, and they are like ribbons that float in the wind around the building.

With stars as embellishments, stardust as foils, and rivers as ornaments, this is the great building that Xiao Yu discovered at this moment that made Xiao Yu feel extremely shocked and incredible.

It is roughly the color of the sun at dusk. There is a hint of red in the gold. It's like the rays of the sun at dusk are shining on it.

"It's a veritable twilight zone...... Twilight......" Xiao Yu muttered to himself.

After recovering from the initial shock, Xiao Yu immediately began to think about the next questions. The questions are simple. It's also straightforward, that is, who built this building? What was the purpose of building this building? How did such a great and incredible building come to be?

Xiao Yu almost immediately affirmed one thing, that is, to build such a great building, if there were no rules and technology, if there was no change in some rules, then it would not have been possible. This also means that the great civilization that built this building is at least the level of an eighth-level civilization, and it is an extremely strong eighth-level civilization. And here, is the world of the rebels......

A name suddenly appeared in Xiao Yu's mind.

"This is the base camp of the Rebel Alliance." Xiao Yu said silently, "It is basically impossible for another powerful eighth-level civilization that has no connection with the Rebel Alliance to appear in the rebel world. Here, only the rebel alliance meets this qiē condition, and only they have such great power. ”

"I, I actually came to the area around the rebel alliance base camp unconsciously......" Xiao Yu felt a little unbelievable in his heart. But what to do next, Xiao Yu knew very well in his heart.

"You can't go any closer here. I'm probably an unpopular intruder in the Rebel universe, and I've been able to quietly thrive here because of my musical civilization. If I had been discovered by the Rebel Alliance, I would have ended badly, as they were already very hostile to me. Xiao Yu immediately made a decision, immediately stopped advancing, and began to do his best to hide his whereabouts according to the guidance of the technology he mastered.

In the future, the wisest choice is undoubtedly to leave here, the farther away from here the better, it is best to find a person who no one cares about, and quietly complete his transformation from a seventh-level civilization to an eighth-level civilization there. But Xiao Yu couldn't leave here. No one stopped Xiao Yu from leaving here, it was Xiao Yu himself who stopped Xiao Yu from leaving.

This great building, as well as these strange phenomena around this building, are like strong magnets attracting iron filings, so that Xiao Yu can't leave at all. Xiao Yu has reached the pinnacle of the seventh-level civilization, and if he wants to become an eighth-level civilization, it will be very difficult if there is no new source of technology. The rules system here seems slightly weird......

Xiao Yu sensed that the closer he was to this great building, the higher the tenacity of the rules became. Specifically, at a distance of 10,000 light-years from this building, Xiao Yu could use one unit of energy to destroy the rules in the space and return it to chaos, while at a distance of 8,000 light-years from this great building, it might take two units of energy to achieve its goal.

Xiao Yu didn't dare to slack off, Xiao Yu quietly divided a part of the fleet, adopted the concealment mode of the highest range, and spent nearly a thousand years again in a curved way, and came to the other side of this building at a distance of no less than 50,000 light years from this building.

The truth did not surprise Xiao Yu, even on the other side of this building, Xiao Yu still detected this strange phenomenon, the closer to this great building, the stronger the rule toughness, and the farther away from this great building, the lower the rule toughness.

This situation couldn't help but make Xiao Yu have a guess.

"Perhaps, this building is the source of the rules in this universe. The strange power of the rules spreads from this great building to occupy the entire universe. This is the center of the whole universe, it is the heart of the whole universe. It's not just the Twilight Zone, it's not just the base of the Rebel League, it's the heart of the universe. ”

This is undoubtedly the center of the universe. Anything that is in this universe is controlled by this great building. Whether it's an interstellar dust orbiting a river at infinity away, or a star exploding farther away, or even a low-level intelligent creature on a planet sucking up some thick, nutrient-rich liquid, all actions, all events, all things in this universe are controlled here. Because this is the center of the rules, the rules that are followed in this universe spread to the entire universe from here.

This is the great power that controls the entire universe, and as long as it is in this universe, it is controlled by this building. Even Xiao Yu is no exception. Only an eighth-level civilization can not be dominated by this building, but Xiao Yu is only a seventh-level civilization.

It's ubiquitous, but it's extremely hidden. It is impossible to find this unless the level of civilization is high enough to reach a certain level. Even Xiao Yu only discovered this in his aimless wandering.

At this moment, Xiao Yu has fallen into a bottleneck, and Xiao Yu is once again stuck between the seventh-level civilization and the eighth-level civilization as if he is in the three-dimensional universe, unable to take a step forward. This has been proven by nearly a thousand years of painstaking research and exploration. Xiao Yu needs an opportunity to break through the current shackles. But Xiao Yu was never able to find this opportunity.

Now, Xiao Yu clearly realizes that the opportunity he needs is ahead, hidden in this great building. In this building, there is something that I have been looking for. But Xiao Yu didn't dare to go over. That's too risky. At this moment, Xiao Yu cannot be the opponent of the Rebel Alliance, and this is the base camp of the Rebel Alliance.

couldn't get any closer, but Xiao Yu didn't want to leave.

"Then wait here quietly." Xiao Yu thought silently, "In this place, the Rebel Alliance probably won't be able to find me. I'm here to develop silently, hoping to find a way to become an eighth-level civilization. ”

But Xiao Yu's plan to develop quietly fell through once again. Xiao Yu noticed that the rules in his environment suddenly shook, and it was an extremely violent, very unusual vibration. It seems that a force is peering into this universe, it has not come here from any direction, but it has made it here, to the greatest building in this universe, the heart of the entire universe, next to the base camp of the Rebel Alliance.

Xiao Yu could only hide beside him and look at this qiē in horror. (To be continued......)
