It is not strange to see the Earth in the Andromeda Galaxy, after all, the Earth just exploded more than 100,000 years ago, and the light carrying the Earth's explosion has only just advanced more than 100,000 light years, and it is still early to reach the Andromeda Galaxy. What you see in the Andromeda Galaxy at this moment is still the picture of the time when the Earth was intact. It's not strange to see the Earth, it's strange to see the Earth's orbit at the moment.

In terms of time and distance, roughly speaking, what Xiao Yu is seeing at this moment should be an image of the earth 2.5 million years ago. However, Xiao Yu was very surprised to find that the image of the earth he observed should be five million years ago. This is 2.5 million years off from the theoretical scenario, and the distance between the Andromeda Galaxy and the Milky Way is exactly 2.5 million light-years.

Xiao Yu's heart gradually sank. There is an explanation that can explain what Xiao Yu is encountering now, but this explanation is so absurd that it is unacceptable.

This explanation is that the Milky Way has gone back in time, and the entire Milky Way has returned to five million years ago, and then the light carrying the image of the Milky Way took two and a half million years to reach the Andromeda Galaxy, which was seen by Xiao Yu at this moment.

If it is explained in this way, then everything can be explained, everything that Xiao Yu saw, including the supernova explosion, the earth two and a half million years ago, etc., has been reasonably explained. But...... Xiao Yu clearly just left the galaxy thousands of years ago!

There was such a thing as going back in time, when Xiao Yu was still weak. It happened once under the leadership of the Taihao civilization, but that time turned out to be nothing more than a lie, and in that incident. Xiao Yu also completely denied the possibility of turning back time through various inferences. Even if Xiao Yu has now become a seventh-level civilization, Xiao Yu still doesn't think that going back in time is something that can really happen in the universe.

The reason is still the same reason that Xiao Yu had when he was still weak - if you want to turn back the time of a star system, you must affect the entire river system, and if you want to turn back the time of the entire river system, you must affect the rest of the river systems around this river system, and so on the chain reaction. Eventually, it affects the entire universe. And it is obviously impossible to turn back the time of the entire universe.

Xiao Yu's heart suddenly moved. Xiao Yu thought of another possibility. The progress of science and technology has greatly broadened Xiao Yu's horizons, and Xiao Yu has been exposed to more things, within the scope of the existing theoretical framework. Xiao Yu began to think about the possibility of going back in time again.

"If the rules are changeable and artificial, then going back in time is not impossible. For example, if I make the rules of a small universe, I can completely flip the rules of this small universe upside down, so that I can do it. The effect happens before the cause. In this universe, it is not because a person accidentally overturns a cup that the cup breaks, but because the cup is broken, that causes the person to accidentally overturn the cup. Is this entirely doable, or is it possible that someone has changed the rules within the galaxy to turn back the galaxy's time? But why didn't the time reversal of the Milky Way affect the rest of the river systems? Xiao Yu's mind was chaotic, and he couldn't figure out a clue.

No matter what explanation is used to explain the scene that Xiao Yu saw at this moment. There is a final conclusion that is extended, and that is. In the middle of the galaxy, something strange is happening.

This is a big premise. Since we cannot think through this premise, we will put this matter aside for the time being, and only use this conclusion as the basis for further inference.

"Now all we need to think about is, why is this weird thing happening in the galaxy? Was it intentional by some being, or did the natural evolution of the universe occur naturally? On the whole, it is more likely that one of them was intentional. So...... What is it that exists, and for what is it that has done such a thing? ”

"They...... Is it targeting me? At this time, such a thought suddenly popped up in Xiao Yu's heart. After all, he is the only seventh-level technological civilization in the galaxy, and his birth seems to be inextricably linked with some cosmic secrets.

"Is this hurting me, or is it helping me? However, I have long since left the galaxy, and even going back in time is unlikely to affect me, and if it is to help me, what does going back in time have to do with me? This thing, except for being weird, can't affect me at all, and if it's aimed at me, it doesn't seem necessary to do such useless work. Xiao Yu thought slowly.

"Or are they just laying a trap in the galaxy to try to lure me back with this strange situation, and then do something against me?" Xiao Yu thought of another possibility.

This possibility is not impossible, although the existence with the ability to reverse the entire galactic time is definitely stronger than Xiao Yu, according to normal thinking, it seems that there is no need for them to influence Xiao Yu in this way. But Xiao Yu knew that there was no absoluteness in anything, just like the white dwarf beast he encountered at the beginning, no matter how he speculated at the time, he couldn't guess that the white dwarf beast would have malicious intentions towards him, but in the end he was still fighting his own idea.

"It's something I can't refuse." Xiao Yu sighed silently, "The Milky Way is my hometown after all, and if something like this happens there, I have to go back and take a look no matter what." Even if there is no such relationship, in the galaxy, there are still people I care about, the Pegasus civilization, the Shenzhou civilization, and my compatriot, Zhang Shengya......"

"Even if this incident is aimed at me, I have to go back and take a look, and I have to figure out these things." Xiao Yu sighed and made a decision. The time spent in the core of the Andromeda Galaxy was enough, and Xiao Yu once again embarked on a long journey.

Since he eliminated the Sweeper civilization, there seems to be a faint connection between everything that has happened, but Xiao Yu at this moment can't find this line. Everything presented in front of Xiao Yu was shrouded in a layer of fog, and Xiao Yu couldn't find out the truth behind these things.

"I have become a real seventh-level civilization, and the Cluster-level battleship has also been manufactured by me, at this moment, my combat power has the strength to escape even in the face of a seventh-level civilization in terms of war, and my ability to resist risks is enough, then, go back to the galaxy and find out the truth behind all this." Xiao Yu made up his mind.

The space inside the battleship that Xiao Yu created at the moment is not an independent space separated from the big universe in the small universe, but through advanced space technology, through means such as condensing, folding, and overlapping the space, this relatively independent space is created inside the battleship. Therefore, there is no way for different warships to coincide, Xiao Yu does not have the ability to put a smaller spaceship into the space of a large spaceship, and the overlap of different warped spaces will bring a series of unpredictable consequences.

At the same time, this new type of spaceship of the seventh-level civilization cannot break away from the large universe and enter the small universe through the large and small universe connection technology. Doing so would result in the loss of space inside the spaceship. Of course, it is still possible to enter the small universe by passing through the space bridge. However, this is more troublesome, it is only suitable for use in tough battles and not for use in long-distance travel, so seventh-level civilizations generally do not have small universes, and after becoming a seventh-level civilization, Xiao Yu also abandoned his original small universe.

In order to solve this problem, Xiao Yu specially created a carrier spaceship, which has no folded space inside, it is just very large in size, even almost the size of a planet. Xiao Yu's spaceships with poor maneuverability were placed in such carrier spaceships, and along with the stars with stronger maneuverability, planetary or continent-class battleships, they began to set off towards the galaxy.

Xiao Yu advanced at a speed of 1,500 times the speed of light. At this rate, Xiao Yu will reach the galaxy in less than two thousand years. Moreover, during the long journey, Xiao Yu does not need to worry about the lack of energy. After mastering the formula of empty energy, the ubiquitous space is Xiao Yu's best source of energy.

More than 70 years later, Xiao Yu reached the edge of the Andromeda Galaxy from the core of the Andromeda Galaxy, and then continued to move away. The huge Andromeda Galaxy gradually began to shrink from occupying the entire field of view in Xiao Yu's eyes, and finally completely revealed its full picture in Xiao Yu's eyes, and then continued to shrink, revealing a clear swirling structure.

At the same time, the Milky Way is gradually increasing its brightness. It gradually began to brighten from a dim point of light, revealing more information. Xiao Yu has not relaxed his observation and monitoring of the Milky Way, and now, Xiao Yu is becoming more and more sure of the strange events that have occurred in the Milky Way.

The information that Xiao Yu has observed all shows that the Milky Way has returned millions of years ago. More than 1,900 years later, when Xiao Yu really stepped into the galaxy, Xiao Yu finally completely affirmed this.

Xiao Yu has traveled millions of light-years to his hometown, the Milky Way.

"Just let me see what's going on here...... Xiao Yu muttered to himself. (To be continued......)
