Xiao Yu is already getting farther and farther away from the Milky Way, from the Great Magellanic Galaxy, which has been destroyed and then reborn. Xiao Yu is about to embark on another long-distance voyage, and what awaits Xiao Yu in front of him will be a long voyage of 7,000 years.

That's right, even with Xiao Yu's average speed of light of 1,500 times the speed of light at the moment, it would take nearly seven thousand years to reach Xiao Yu's destination this time. Xiao Yu will leave the fairy-Milky Way Group and head to the other galaxy group closest to here, the Maffei Group. In the Mafei galaxy group, there is a river system named Mafei I by Xiao Yu, and this river system is the target of Xiao Yu's voyage.

The position of the Maffei One Galaxy in the Maffei Group is equivalent to the status of the Andromeda Galaxy in the current group of galaxies. Maffei is the largest river system in the Maffei Group, with a diameter of about 60,000 light-years, which is slightly larger than half the size of the Milky Way and larger than the Triangulum galaxy.

There are about 80 billion stars orbiting in the Maffei One system. Overall, it is a fairly ordinary river system, but its location can be a springboard for Xiao Yu to go to the Virgo galaxy group in the future. With Xiao Yu's technology at the moment, although he can directly obtain energy from the void, the transformation from space to the various materials he needs is still limited by his production capacity, in this case, it is still quite necessary to find a river system as a springboard and a material replenishment point during the journey.

The Andromeda Galaxy, the Milky Way, and the Triangulum Galaxy, as well as numerous tiny and dim satellite galaxies, make up the Fairy-Milky Way Group. Because this group of galaxies is the birthplace of humanity and the location of the Earth. Therefore, this group of galaxies is also called the local group of galaxies. The Local Group is an astronomical unit one level larger than the River Group, and the closest neighbor to the Local Group is the Maffei Group.

Nymphs - Milky Way galaxy group. The Maffei Group, the Celestial Furnace Group, the Auriga Group, the Virgo Group, etc., together constitute a higher astronomical unit - the Virgo Supercluster. The Virgo Supercluster is also known as the Virgo Supercluster because it is the birthplace of mankind. Then the Virgo Supercluster, and the Pisces-Cetus Supercluster. The Perseus-Pisces supercluster, as well as the Auriga supercluster and the Hercules, once again constitute a higher astronomical scale. Pisces-Cetus supercluster complex.

The astronomical structure of the supercluster complex is still far from the current visible universe. The vastness of the universe is evident in the fact that it is a great being that simply surpasses the limits of the imagination of all intelligent beings. Here, endless stars. Black hole. River systems, galaxy groups, super-galaxy groups, etc., follow the rules of the underworld, and operate here for hundreds of millions of years.

There are endless mysteries hidden here, and endless wonders and beauties waiting to be discovered by intelligent beings.

Sometimes, just thinking about these dazzling large-scale structures, Xiao Yu will feel a surge of blood in his heart. You can't help but feel a wave of lightheadedness. It's just too big, so big that it's desperately big. Even if Xiao Yu is already a seventh-level civilization at the moment. He could already travel at fifteen hundred times the speed of light, and Xiao Yu still felt so small. It would take nearly 7,000 years just to leave the local group of galaxies and go to the nearest Maffei group, let alone leave the local supercluster, or leave the local supercluster complex.

"The universe is so vast, and the range of activities of the seventh-level civilization is only so small in comparison, I don't know what kind of height the eighth-level and ninth-level civilizations can reach...... It's fascinating to think about. Xiao Yu sighed silently in his heart.

At this time, Xiao Yu began to somewhat understand the meaning of the existence of a seventh- or eighth-level civilization in the direction of travel. Simply speaking, it seems like a great waste or an insult to life to devote all of your infinite life to something like traveling. But the universe is so infinite and so magnificent, what's wrong with spending time on travel?

Even, if Xiao Yu didn't have so many mysteries and missions, Xiao Yu would have the urge to develop himself into a civilization in the direction of travel. It seems like a good idea to spend millions of years on a long journey. Sometimes, Xiao Yu really wants to ignore all this, just choose a random direction and sail for 1.8 million years first. Anyway, it has become a seventh-level civilization, so there is no need to worry about the source of energy.

Every time this impulse popped up in his heart, Xiao Yu needed great self-control to suppress this thought. Xiao Yu constantly admonished himself to be down-to-earth and develop step by step. As long as your own technology is developed, you can start your own cosmic journey in a more energy-saving and time-saving way.

Whenever this time, Xiao Yu will feel a little lamented about the days when he was still on the earth. It's just a small planet, and in this vast and vast universe, not even a speck of dust can be compared. However, there are so many of their own kind, for a little thing that is too small to be insignificant, there are all the organs, flies and dogs.

It was a ridiculous bunch of creatures, a ridiculous time.

After more than 1,500 years of voyage, Xiao Yu arrived in the Andromeda Galaxy. After a rough exploration of the Andromeda Galaxy, Xiao Yu confirmed one thing, that is, the Andromeda Galaxy did indeed go back in time, just like what happened in the Milky Way. The flame civilization is gone, the members of the Andromeda Galaxy Alliance have all disappeared, and even the Andromeda Galaxy has no technological civilization in existence. This was expected by Xiao Yu for a long time, and Xiao Yu was not too shocked by this.

After staying in the Andromeda Galaxy for about 400 years, Xiao Yu passed through the Andromeda Galaxy, came to the other edge of the Andromeda Galaxy, and began to set off towards the Triangulum Galaxy.

The Triangulum Galaxy is one of the three giants of this galaxy group, and it is also the only large river system that Xiao Yu has not explored. At this moment, before leaving this galaxy group, Xiao Yu has to go and explore it no matter what.

"The Guardian Civilization started a voyage across the river system with the scientific and technological strength of a sixth-level civilization, and this move has to be said to be indeed very courageous. However, based on their technological and sailing speed at that time, it took them more than 20,000 years to reach the Triangulum galaxy from the Milky Way. At this time, they were only halfway through their voyage. Xiao Yu thought silently, "Okay, let them develop, it's just a sixth-level civilization, it's not worth my time wasting time looking for them in this starry sky." Or...... I can leave something in the Triangulum galaxy and give them a little help. Or maybe I'll explore the triangulum galaxy first, and if there are too powerful civilizations, destroy them first, and clear a little obstacle for their arrival. After all, they are all civilizations that came out of the galaxy, and I'm leaving my own galaxy group, so it's reasonable to help them. ”

There is a grudge between Xiao Yu and the Guardian Civilization, but those things are nothing in Xiao Yu's eyes at this moment. It's like when people grow up, the grudges between them when they are children disappear. Even, if necessary, let Xiao Yu help the Guardian Civilization, Xiao Yu is also willing.

With this in mind, Xiao Yu once again spent about 700 years coming to the Triangular Galaxy. The Triangulum Galaxy did not go back in time, which Xiao Yu knew, and to Xiao Yu's surprise, there were no intelligent beings in the Triangulum Galaxy. If it was just like this, Xiao Yu was not so surprised, what surprised Xiao Yu was that there were many relics of civilization in the Triangular Galaxy.

Xiao Yu was exploring here, and many conclusions appeared in Xiao Yu's mind.

"This is the residence of a third-level civilization, and they obviously haven't mastered the curvature navigation technology yet, but it's strange why is there a relic of a fourth-level civilization so close? Could it be that this third-level civilization is a vassal of this fourth-level civilization? No, no, there are still the remains of a fifth-level civilization here, and there are also sixth-level civilizations...... It was empty, and it was clear that something had deliberately erased the traces of existence. Although there is no direct evidence, I believe that there must have been a seventh-level civilization here. ”

"Could it be that in this galaxy group, in addition to me, there are other seventh-level civilizations?" Xiao Yu pondered this question with doubts, "A seventh-level civilization, a large number of sixth-level or lower low-level civilizations, how can this be so similar to the existence of the Civilization Alliance?" Moreover, the ruins here are not very old, and it is clear that they have just left - no more than two thousand years at most, why did they leave in such a hurry, and it seems that they deliberately concealed their traces? ”

The scene here made Xiao Yu very puzzled. But no one is destined to solve this mystery for Xiao Yu. After thinking about it for a while, Xiao Yu still decided not to delve into it here.

"Whatever it is, it has nothing to do with me anyway. Let's go, get out of here and head to the Maffei One system......"

Xiao Yu reversed the course of the fleet and headed towards the distant river system in the void. Unexpectedly, at this time, a little sign of spatial fluctuation was detected by Xiao Yu.

"Spatial fluctuations? Curvature sailing? Nearby, ships with sapient beings are sailing in curvature! Xiao Yu determined this in an instant. (To be continued......)

PS: The fifth watch is over...... Exhausted...... Drink and go.

Hey, I'm very depressed. Because of some unavoidable reasons, even though I know that something is wrong, I still have to do it, and I have to hurt my dearest people, this feeling......

I don't have a place to talk, so I have no choice but to say it here, I hope it won't affect everyone's mood of reading.
