According to Mu Cang's estimation, without his intervention, in about five billion years, the sun in its old age will be two thousand times brighter than it is now.

Therefore, the galactic center field, where tens of thousands of aging stars are gathered at a high density, is bright enough to blind the eyes of all weak creatures, and may even be turned into ashes by the terrifyingly powerful sunlight.

The fundamental reason why so many huge stars can gather in the Galactic Center and rotate closely together is the existence of the large black hole in the Galactic Center.

From the memories of Kedelon and Pan Lei, we know that this behemoth located at the center of the Milky Way, with an event horizon diameter of 24 million kilometers, has a mass of approximately 4.3 million solar masses.

Such a huge mass naturally brings extremely huge gravity.

Only in this way can so many stars dormantly rotate around it with sincerity.

However, although the motion states of many stars in the galactic center region will be significantly affected by the central black hole, it does not mean that the hundreds of billions of star systems in the entire Milky Way are also respected by it.

For example, many star systems in the Orion spiral arm, which are extremely far away from the galactic center, are almost unaffected by the gravitational pull of the black hole.

The reason why this is so is very simple.

Because the Milky Way is really too big.

The galactic core bulge and the galactic disk alone, as well as the large amount of invisible but invisible dark matter that exists between the two, all possess a power far greater than the mass of the central black hole.

In other words, these areas all possess strong absolute gravity due to their huge mass.

Therefore, except for the aging stars in the galactic center, most stars in the Milky Way do not revolve around the central black hole, or in other words, they revolve around more than one of them.

In the vast galaxy, every celestial body has a gravitational force, which may be large or small, strong or weak.

From a larger macro level, this power may be insignificant when taken alone, but once added up, it is an unparalleled and huge force.

Just like a certain low-spirited star system that exists deep in the spiral arm of Orion.

Perhaps it has also been affected by the extremely weak gravitational pull of the galactic center black hole.

But at the same time, it is more affected by the gravitational pull of a large number of other star groups in the distance and dark matter clusters.

This is the complexity of the gravitational interaction between the galactic celestial bodies.

In the memories of Kedron and the two, Mu Cang also saw that the six major ethnic groups living in the terrifying galactic center area, except for Youn who was born in the dust cloud in the high temperature and high pressure core of the nebula, had a strong desire to fight.

Rook civilization.

Except for the Pengruite Immortal clan, which is mediocre in combat power but has powerful natural psychic abilities and extremely long lifespan.

There is also a giant plant life group that claims to be the protector of life but is actually a biochemical experiment maniac - the Pelodi Tree of Life Civilization.

And the Loveling civilization, which is short in stature and average in physique, but naturally powerful in spirit, proficient in all kinds of strange magic, loves interstellar exploration and treasure hunting, and looks miraculously similar to the Blue Star cats.

When seeing this piece of information, Mu Cang recalled and thought:

"So that's it. The predecessor of the Zhouguang Tiger probably came from this so-called Loveling civilization."

Finally, there are two equally powerful Anel civilization, which ranks first and second among the six galactic tribes, and the Yin En civilization, which calls itself the Galaxy Shepherd.

These six major galactic civilizations are all so-called extraordinary ethnic groups.

That is, any individual within the ethnic group must be an extraordinary and powerful race as soon as he is born.

This is an... extremely terrifying advantage.

Throughout the galaxy, individuals from countless civilizations and countless intelligent groups almost all start from the mortal stage, practice and evolve, and then reach the extraordinary step by step, and then overcome various difficulties and obstacles, and finally reach the pinnacle of the extraordinary before they are qualified to look up to the overlord.

Rank.

But the Six Yinxin Clans are born with extraordinary lives. Under such a favorable premise, except for a very small number of individuals with poor qualifications like Pan Lei, most of the members of the Six Clans can achieve great success with just a little effort.

It is easy to practice to the extraordinary peak.

There are almost no obstacles in this process, only there will be some difficulty when advancing to a higher level of galactic overlord.

But for the large number of geniuses from the six galactic races, this is not too difficult.

Therefore, the number of galactic overlords among the six races can be regarded as a truckload.

There are so many of them that once they are deployed in formation, they are enough to wipe out all the thousands of interstellar civilizations outside the galactic center along the way.

Not to mention, they also inherited many relics from the Star Eater clan of previous civilizations.

Eliminate the above.

Mu Cang even saw that the number of cosmic sages in these six major ethnic groups was actually close to a hundred.

You must know that in the entire Orion spiral arm, and even when Kaidelon traveled through various regions of the galaxy, he never saw a genuine cosmic sage.

However, in his memory, he also saw that these powerful ethnic groups who have been living in the galactic center area and rarely go out. In addition to the Yunluk, who is rich in fighting maniacs, and the Loveling family, which is rich in interstellar adventurers, there are also shuttles.

Searching for various low-level civilizations to conduct biological experiments on the Pelodi Tree of Life throughout the galaxy.

The other three major ethnic groups basically have little interest in the outer galaxy with low spiritual energy activity, and only care about many affairs within their own civilization's territory.

Moreover, the sphere of influence of these six races is not located in the starry area where the number of stars is overcrowded, but exists around the most dangerous black hole in the center of the Milky Way.

It is also the location of the legendary testing ground for gods.

In Kedelon's huge memory that lasted for tens of thousands of years, Mu Cang saw that in fact all the six races in the galactic center lived in a research center called [Sanchegos] built around the black hole's horizon.

In the midst of extremely large structural projects.

What is the ultimate megastructure?

If the Dyson Sphere is the pinnacle of interstellar civilization in terms of cosmic megastructure engineering technology.

So Sanchegues, who has a partial Penrose sphere structure, is another engineering miracle that completely surpasses the Dyson sphere in all aspects.

The so-called Penrose sphere is a large-scale energy-draining device that continuously extracts a large amount of thermodynamic free energy from a black hole through the Penrose process.

The working principle is very simple.

Generally speaking, when a black hole spins, it drags the surrounding space and time, forming a circle of areas called the 'energy sphere' outside the event horizon.

In this area, because the three-dimensional space-time is extremely dragged by the black hole, the objects inside it will not be in a stationary state relative to observers in the more distant starry sky.

Because the ergosphere is outside the black hole's event horizon, objects that enter this area still have a chance to escape.

If when material is thrown into a black hole, the appropriate speed and angle are selected at the right time to enter the energy layer and then automatically disintegrate.

Part of it fell into the horizon, and the other part flew out of the ergosphere.

So as long as the trajectory is appropriate, the kinetic energy of objects flying out of the black hole's outer energy layer area will exceed the kinetic energy of objects flying into it.

This excess kinetic energy comes from the rotational kinetic energy of the black hole itself.

However, according to Kedelon's memory, the deep structure of Sanchegos is not just as simple as a Penrose sphere.

It's much more complicated.

From the appearance and function point of view, this super structure is almost a man-made...'prehistoric world'.

Sanchegos is a star with a thickness ranging from hundreds to thousands of kilometers and a diameter of two trillion kilometers. It surrounds nearly half of the black hole at the center of the Milky Way, and its surface is covered with rivers, lakes, seas, mountains, continents, and thousands of

Thousands of huge spheres with various types of mild or extreme natural environments.

But why is it said that it only wraps nearly half of the black hole?

Because this huge project... is incomplete.

Since Kedelon can remember, and at the same time, according to the records of the long civilization history of the Yunruk family that lasted for millions of years.

This Sanchegos seems to have always been incomplete, and can even be said to be extremely damaged.

It seems that a very long time ago, some extremely terrible disaster happened in the galactic center.

As a result, its current area is only one-third of its theoretical complete area.

And even this third was broken into hundreds or thousands of pieces.

However, even if it is broken to this extent, even the smallest one among these numerous broken plates has an area one hundred thousand times the total area of ​​Blue Star.

The six largest areas were completely occupied by the six races of the Galaxy a long time ago.

It is also for this reason that the main body of civilization of the six races in the Milky Way is based on the Sanchegos plate, supplemented by a few planets on the periphery of the galactic center area.

As for the more distant interstellar regions, the six races also looked down upon them at all and regarded them as low-spirited and barbaric areas.

"Sanchegos, the starry sky continent outside the black hole is really an interesting idea."

After reading this piece of information, Mu Cang suddenly became excited and wanted to build a Sanchegos of his own.

Just do it if you think of it.

Buzz——

Under his majestic will like a god, the dozens of naked singularities located in a huge four-dimensional unit cell of Dongtian's first clone suddenly trembled and gathered together.

Wow——

In a violent vibration of space and time, these naked singularities suddenly condensed into one, and were instantly transported by the dimensional rift into a certain three-dimensional space-time unit cell of the second avatar.

As soon as this naked singularity appeared in this empty three-dimensional space, it suddenly turned into a sound black hole with a complete structure, and its mass skyrocketed without swallowing any matter.

This is also Mu Cang's handiwork.

He has almost complete control over these space-time cells in his body.
