At the same time, at the very core of the Milky Way, there is a huge black hole, with an event horizon limit of 20 million kilometers alone, and any object that enters within 20 million kilometers of it will be completely pulled into the abyss, and there is no possibility of escape. Pen % fun % Pavilion www.biquge.info

20 million kilometers away, a large amount of matter is torn into pieces by its strong gravitational pull, the violent friction between substances and the gravitational tidal effect make the matter convert into energy with the highest efficiency, and the fusion reaction hundreds or even thousands of times stronger than the sun turns the area around the black hole into a sea of fire, which is the accretion disk formed by the black hole.

Just beyond this sea of fire, countless huge warships floated in space, these warships were so big, the smallest were larger than the human Battlestar class warships, and the largest was even more than 100 kilometers, like a planet.

In a huge spaceship, a group of creatures are working on various machines, seemingly experimenting on some kind of experiment, these creatures are also humanoids, all tall and muscular, with skin as steely as metal.

They are the only pinnacle high-civilization empire in the galaxy, the Valley Wind Empire.

The Valley Wind Civilization originated in the Valley Wind Galaxy, which is located at the core of the Milky Way, only hundreds of billions of kilometers away from the giant black hole.

The environment around the black hole is very harsh, a large number of planets and even stars attracted by gravity are constantly colliding, and few civilizations can continue long enough to give birth to life, but the star system where the valley wind is located is very lucky, and it has never suffered a huge disaster in the process of billions of years of evolution, so that the valley wind civilization can develop smoothly.

And being so close to the black hole also makes the Gu Feng civilization's research on energy and even space much faster than other civilizations, since the birth of the intelligent civilization, it has entered the advanced civilization in just 50,000 years, and then after another 10,000 years, it has entered the peak advanced civilization world.

Since entering the peak advanced civilization, the Gufeng civilization has experienced 50,000 years, and in these 50,000 years, they have conquered dozens of civilizations, and the empire area is more than 20,000 light years away, it can be said that the status of the hegemon of the galaxy is well-deserved.

However, since 10,000 years ago, the Gufeng civilization has stopped expanding outward, and is dedicated to conducting research near this huge black hole.

The pinnacle advanced civilization was already able to create a subspace, and the curvature speed reached the limit of this universe: 1,296 times the speed of light.

That's right, the fastest space layer in the universe is 1,296 times the speed of light.

Now the Gufeng civilization can create subspace, and it has been applied in many ways, a planet can be wrapped in a large subspace, but it is only the size of a room from the outside.

In addition, when traveling through time and space, creatures manipulate the subspace to attach to the surface of the outermost space of the universe to "glide", and the fastest speed can reach 2,000 times the speed of light.

However, the Gu Feng civilization has long found that their subspace technology has not yet reached the extreme, and the real ultimate is to create a space that is completely different from the rules of this universe, so as long as you jump out of this universe, you can do it, and at that time, the shuttle speed is likely to achieve 10,000 times the speed of light, 100,000 times the speed of light, or even millions of times, and this civilization is likely to be the legendary god-level civilization.

A god-level civilization is the ultimate civilization in the universe.

Human beings can't imagine this kind of civilization now, even the Kraxing civilization will not have the concept of god-level civilization, and only when the control of the space layer reaches the extreme will it realize the existence of this higher level of civilization.

Even the Gufeng civilization has only made some progress now, and this sign is the discovery of source energy.

What is source energy? It is the most mysterious energy in the universe, of course, this energy does not necessarily come from this universe, it is likely to come from outside the universe.

This kind of energy is extremely rare, and it cannot be extracted in ordinary environments, and it is only possible in some extreme environments, such as black holes.

However, not all black holes can extract this source energy, only the extraordinary gravitational pull of large black holes can extract a little source energy.

The black hole at the center of the Milky Way is a black hole that can extract source energy.

What is the use of source energy?

To put it simply, it is the foundation of a higher-level subspace, which is not the subspace that the Gufeng civilization has mastered now, but an independent space world that can really jump out of this universe and exist alone.

In the final analysis, the subspace created by the current Gufeng civilization is still formed by the spatial layers of this universe, and no matter what, it still has to rely on the universe, and it cannot leave this universe.

However, the subspace created by using source energy is a completely independent universe, and it can easily travel outside the universe.

Of course, the Gu Feng civilization is still far from this level, and all they can do now is use the source energy to travel through the universe over a longer distance.

You must know that even if the Gufeng civilization reaches the extreme speed of light with a curvature of 1,290 times, it will take seven or eight years to travel through the Milky Way with a diameter of nearly 100,000 light years, and it will take nearly 200 years to reach the Andromeda galaxy more than 2.5 million light years away, not to mention those more distant constellations, even if the maximum curvature is tens of thousands, hundreds of thousands of years or even longer, so if you want to achieve real interstellar travel, the maximum curvature is far from enough.

And a tiny source energy substance can instantly travel for decades or even dozens of light years, which is the ultimate energy source for interstellar travel now.

Of course, even for such a huge black hole, it is extremely difficult to extract source energy from it.

Therefore, most of the energy of today's Gufeng civilization is spent on this huge black hole.

"Extraction Ship No. 3 has been working for a hundred years and needs to be repaired. ”

Several crew members of the planet-like battleship were operating the equipment.

Suddenly, there was a "tick-tick" sound from the battleship, which was extremely pleasant to the ear, and people were shocked when they heard it.

"Huh?"

Everyone shouted, and the sound of this sound meant that there was another source of energy that had been successfully extracted.

"No! the source energy radiation source is not from a black hole, this is not the source energy ...... we extracted!"

It didn't take long for someone to find out about the problem.

"What? Not from a black hole? Where did that come from?"

All the Gu Feng Xingren jumped up, the source energy can only be extracted in the black hole This is the most basic common sense about the source energy theory, and in the Milky Way, only the central black hole will exist, if the source energy fluctuation just observed is not from the black hole in front of you, then where did it come from? Could it be from another galaxy? The nearest galaxy is the Andromeda Galaxy more than 2.5 million light-years away, and it can be so violent at such a distance, could it be that all the stars in the Andromeda Galaxy have been pulled into the black hole?
