Xiao Yu had already led all his warships into the Star Gate. This stargate is intact, Xiao Yu can be sure of this. However, Xiao Yu didn't know what the process of traveling through the Star Gate was like, and he didn't know where the destination was. This means a certain risk, but Xiao Yu doesn't care.

Compared to the possible gains, this risk is well within the acceptable range. The ruins of an eighth-level civilization are not easy to see, and Xiao Yu hopes that during this trip, he can peek into the mystery of the eighth-level civilization stargate technology.

Stargate Technology is presumed to be made according to the principle of spatial limit bending, which is like drawing two dots on a piece of paper and then folding the paper in half to make the two dots coincide, and you don't need to move to reach your destination. Stargate technology is undoubtedly a more advanced way of space travel than curvature navigation, and if you can get data on this aspect, Xiao Yu's road will be much smoother.

This stargate looks more like the eighth-level civilization in that travel direction is secretly staying here, preparing for its own use in the future. Xiao Yu detected that there were traces of the use of this stargate about 300,000 years ago. More than 300,000 years ago, when the earth was still a barbaric era, human beings were still drinking blood; The Sweeper Civilization and the Guardian Civilization are still fighting, and the Taihao Civilization is still hiding. Without the knowledge of all the powerful forces in the galaxy, a powerful eighth-level civilization quietly went to another place with the galaxy as its starting point.

Now, Xiao Yu will repeat this journey along the path that this powerful eighth-level civilization once walked.

After obtaining enough energy, the stargate was activated. The scenery in front of Xiao Yu's eyes suddenly changed, from the stars in the sky to nothingness. However, this void only lasted for a short time, and after a while, the scenery in front of Xiao Yu's eyes was changed again.

appeared in front of Xiao Yu's eyes. It's still not a normal cosmic landscape. The scenery here is a bit like a kaleidoscope of light and shadow in the space warp shroud.

"I may have left the original three-dimensional universe and entered another three-dimensional world. Just as an infinite number of two-dimensional worlds constitute a three-dimensional world, an infinite number of three-dimensional worlds can constitute a four-dimensional space. Here, that's the rest of the three-dimensional world. Xiao Yu thought silently in his heart, "Light and gravity can both propagate at the four-dimensional level, which means that they can be transmitted to this space from the three-dimensional universe, and the source of the change of light and shadow here should be the space I am in." ”

It takes an infinite number of three-dimensional spaces to form a four-dimensional space, but this does not mean that the theory of parallel universes has been verified. In fact. Science and technology have developed to the present, and the parallel universe theory, which was once all the rage in the Earth era, has been completely rejected by Xiao Yu. The current situation is more like this: imagine the following scene, in an empty room, there is a piece of paper, suspended in mid-air. There is an infinite amount of the rest of the two-dimensional space around it, but the rest of the two-dimensional space is meaningless. Only there is matter on it. Energy as well as living things.

The same is true for three-dimensional space relative to four-dimensional space. Xiao Yu has detached himself from the meaningful three-dimensional space at this moment. came to a "meaningless" three-dimensional space.

"It seems that the stargate created by this eighth-level travel civilization is not a complete stargate technology." Xiao Yu pondered, "The real Stargate Technology Teleportation should not consume time, no matter how far away it is, it should arrive instantly. By now, I've been in another three-dimensional space for more than five hours. ”

Xiao Yu was manipulating his battleship and moving forward. The role of the stargate. It's more like providing a shortcut, but even if it's a shortcut, you have to walk it with your own legs. It is not an automatic conveyor belt.

The so-called thorough stargate technology still uses two-dimensional space. A piece of paper is used as a metaphor, that is, the two dots on the paper are folded so that they coincide completely. In this way, the distance between the two points is zero. Since the distance is zero, there is naturally no need to consume time.

And now the situation is more like the incomplete folding of this piece of paper, that is, it is only folded at a certain angle. In this way, the distance between the two points is still shorter than the straight-line distance, but it is not completely zeroed. It's a shortcut. As for how much distance this shortcut can save, it depends on the technological content of this stargate.

And at this moment, Xiao Yu didn't know the scientific and technological content of this stargate. To what extent the technology of the eighth-level civilization is strong, Xiao Yu does not know. Xiao Yu could only wait silently.

It's been a year now. Through the way of curvature navigation, Xiao Yu moved forward quickly at two hundred times the speed of light in this strange three-dimensional space. The scenery in front of you has always been changing light and shadow, as illusory as a kaleidoscope.

In the second year, Xiao Yu was still on a long voyage. Xiao Yu couldn't help but feel a little worried in his heart. If you get lost in the infinite three-dimensional space and never go back, then the fun will be great. Since the rest of the three-dimensional space is meaningless, then there will be nothing meaningful in such a three-dimensional space. There will be no stars, there will be no planets, there will be no nebulae, there will be no matter and energy. With Xiao Yu's current level of technology, getting lost in such a place will only lead to complete death.

"Maybe I was a little reckless in my previous choice." Xiao Yu thought secretly, "However, if I had to choose again, I would still choose to enter the Star Gate." If I don't choose the star gate, with my current technology and the time to lay the star path, it will take me at least 100,000 years to reach the Andromeda Galaxy. The Guardian Civilization has been busy for nearly a million years to complete the entire Star Path, and by now, they have been set out for thousands of years, but it is estimated that they have not even completed a third of the entire path. Hey, the universe is vast, and no matter how fast it is, it makes no sense to face the infinite universe. ”

Xiao Yu has been waiting silently, waiting for the moment when he arrives at his destination. Xiao Yu's heart is very peaceful, a few years, or even decades, is nothing to Xiao Yu. On the contrary, it was the scenery and physical characteristics of the rest of the three-dimensional space that made Xiao Yu have a strong interest. Xiao Yu once again launched his scientific research action here.

There are many interesting things that Xiao Yu discovered. For example, under normal circumstances, there is no time in these "meaningless" three-dimensional spaces. After the photons came to these three-dimensional spaces from the three-dimensional universe, the physical properties also changed somewhat, and they even lost all their mass and energy.

In the three-dimensional universe, photons have a moving mass but no static mass, but here, the photon linkage mass is also lost. It becomes a pure particle existence entirely, so simple that it has no physical quantity attached to it, and any physical quantity used to describe it is zero, except for velocity.

The speed of photons varies here, and they travel at irregular speeds, sometimes tens of thousands of times the speed of light, sometimes as slow as snails. Time is a physical quantity that describes the motion of matter, and without matter there is no meaning to time. Temperature is a physical quantity that describes the motion of particles, and without matter, temperature is meaningless.

Any laws of physics are invalid here. Any law that is enshrined as truth in the three-dimensional universe is as ridiculous as a joke here. But strangely, the laws of physics were still working in Xiao Yu's fleet. Xiao Yu's normal speed still can't exceed the speed of light in the three-dimensional universe, and he still needs to bend space to navigate with curvature.

This aroused Xiao Yu's strong interest. In addition to the speed of light, temperature, and time, Xiao Yu also measured a lot of data in this three-dimensional world and observed many physical phenomena. Everything here is so novel to Xiao Yu, which makes Xiao Yu puzzled and at the same time, Xiao Yu feels extremely excited.

It is rare to be able to come into contact with physical phenomena at the level of a seventh-level advanced or even an eighth-level civilization when you have not fully become a seventh-level civilization.

Stargate travel didn't last too long, and it proved its superiority in terms of space travel with realistic data. After two years, the scenery in front of Xiao Yu finally changed again.

The familiar cosmic starry sky finally appeared in front of Xiao Yu again. What appeared in front of Xiao Yu was a completely different scenery from the Milky Way. Xiao Yu knew that he had come to a new river system.

Xiao Yu appeared here abruptly like this, and behind Xiao Yu, there was no black hole like Xiao Yu imagined. The space in the front and back and left and right were very normal, and Xiao Yu did not find any signs of space travel. The Stargate journey seems to be a one-way voyage, coming here from the galaxy through the stargate, but not having the ability to return to the galaxy from here through stargate technology.

"Where is this?" Xiao Yu looked at this with some doubts, "I don't know how many light years of the long journey I have spanned in two years?" ”

Xiao Yu is working hard to observe those stars or neutron stars in this river system, trying to find some stars that he is familiar with, so as to determine his position.

But Xiao Yu hadn't found the star he was familiar with, and a message came unexpectedly: "Civilization from afar, welcome to come here." From now on, you are the sweeper civilization of this river system......" (To be continued......
