I didn't care much about it before, I only got what I needed, ignoring the mysterious historical background of the galaxy civilization, but I was sealed by the tree of civilization.

If it weren't for the Heavenly Palace Phantom that suddenly appeared this time, he would have thought that the ethereal things of the Galaxy Civilization would just follow his fate.

It seems that his fate also hides a huge secret.

Caught him off guard.

Again, that question came to mind again.

How to choose such a form?

However, saving my sister, nothing can change Song Xiaopeng's belief in the first place.

But if you save your sister, what should the people of Galaxy Academy do?

And then there's the task of spreading civilization.

Integrate five human settlements.

Now it seems that it is simply an impossible task.

He is not the Holy Lord of the West Shadow who did not become a part of the dark web civilization at the beginning, he has the means to penetrate the heavens and the earth, and left the ten ancient prohibitions before the elimination of the Dao, retaining the primitive human beings of the West Shadow.

But this prohibition, after the change of the Heavenly Palace Phantom, it is clear that it cannot stop the invasion of the dark web civilization. Otherwise, Coconut Pear and Wang Meili would not have been devoured by the huge eyeballs that the black lotus had turned into their own cultivation and true qi.

"Those who have the opportunity should be like thorns and inherit the task of spreading civilization. Regarding the dark web civilization, although it is powerful and terrifying, the prohibition of this mountain village cannot enter it, and it can only steal the cultivation of the people with their imprints, so there is no need to worry. Just when Song Xiaopeng was thinking about the problem and thinking a little autistic, the voice of vicissitudes in the tree of civilization sounded in his mind.

"Is that so?" Song Xiaopeng was stunned for a moment, his thoughts racing, "Then in the Galaxy Academy, there are still people who have been imprinted by them?"

"Not at the moment. ”

"That's good news. ”

"Then tell me about the galaxy!" Song Xiaopeng entered the space of the Tree of Civilization and said quietly to the void that dissolved the moonlight.

The voice of the Tree of Civilization said slowly: "The Milky Way includes 1000~400 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. The total mass of the Milky Way is about 1.5 trillion times that of Tianlan?? , which belongs to the local group of galaxies, and the nearest extragalactic galaxy is the Dwarf Canis Major galaxy, 42,000 light-years away from the Milky Way.

The Milky Way is a barred spiral galaxy, which refers to a spiral galaxy with a short bar shape composed of clusters of stars in the middle. About two-thirds of spiral galaxies are barred spiral galaxies. The short rod usually affects the movement of stars and interstellar gas in the barred spiral galaxy, and it also affects the spiral arm. The spiral arms of the barred spiral galaxy appear to emerge from the ends of the short bars. In ordinary spiral galaxies, stars are gushing directly from the core, and in the galaxy taxonomy, the people of the galaxy civilization are represented by the symbol SB.

The Milky Way is an oblate sphere with a massive disk structure consisting of a bright and dense core, two major spiral arms, and two unformed spiral arms, 4,500 light-years apart.

Tianlan is located on the Orion Arm, a branch of the Milky Way, and the distance to the heart of the galaxy is about 26,000 light-years.

At the center of the Milky Way is Sagittarius A, the source of complex and dense radio waves, and its proximity to the center contains a supermassive black hole, which is considered to be the central black hole of the Milky Way and the closest supermassive black hole to the Hexagram??。

The Milky Way is composed from the inside to the outside, including the Silver Heart, the Silver Core, the Silver Disk, the Silver Halo, and the Silver Crown. The central region of the Milky Way is mostly composed of old stars, and the outer regions are mostly nascent and young stars. There are more than a dozen satellite galaxies scattered over an area of hundreds of thousands of light-years, the larger of which are the Large Magellanic Cloud and the Small Magellanic Cloud. The Milky Way grows by slowly devouring the dwarf galaxies around it.

Most of the stars in the Milky Way are concentrated in an oblate sphere of space, which is shaped like a discus. The protruding part of the oblate sphere in the middle is called the "nuclear sphere" and has a radius of about 7,000 light-years. The middle part of the nuclear ball is called the "silver core", and the surrounding area is called the "silver plate". Outside the galactic disk there is a larger, spherical region where there are fewer stars and less dense, known as the "galactic halo", with a diameter of 70,000 light-years.

In the perception of galactic civilizations, the Milky Way has a rod-like structure composed of stars and dust that crosses the galactic core, is about 27,000 light-years long.

90% of the Milky Way is made up of stars.

There are many types of stars, and according to their physical properties, chemical composition, spatial distribution, and motion characteristics, stars can be divided into five star families. The youngest extreme star family, the stars are mainly distributed in the spiral arms of the silver disk. The oldest extreme star family, the stars are mainly distributed in the galactic halo. Stars often clump together. In addition to a large number of binary stars, more than a thousand star clusters have been discovered in the galaxy civilizations. There are also gas and dust in the Milky Way, which account for about 10% of the total mass of the Milky Way,?? Others are scattered in interstellar space. ”

The tree of civilization told the story, and Song Xiaopeng seemed to listen to a book from heaven.

"Among these nebula gases, there is a civilization like the Dark Ones?"

"Yes, the civilized races that exist in these star clusters are collectively known as the Heavens and Ten Thousand Worlds. The Dark Clan, not surprisingly, is the civilization of the more than a thousand star clusters found in the galaxy civilization world. Of course, it could also be a civilized race in the nebula that was not discovered. ”

"But after such a long distance, how did they come to Tianlan Continent?"

"In the original galactic civilization, there were strong people who could cross, and the scientific and technological means were even more against the sky, and they developed flying machines that could shuttle through the void black holes, reach different nebulae, and enter different racial civilizations. Some people advocate invasion and assimilation, and some people, like the current dark race, directly assimilate the race and become part of their own civilization......"

"What kind of existence is that mysterious civilization that has come to the land of the West now?"

"Presumably a civilization similar to the Dark Race. Don't worry about being stronger than the dark web civilization. The dark web civilization, in the galaxy civilization, although it is not so terrifying, there are other civilizations that can be compared to the existence. Moreover, today's dark web civilization is actually not so terrible, and it is thought that some existences exist in the resurgence of other civilizations and races. ”

"It's like I'm listening to a book, but I know that all I have to do is improve my strength. It's just that it's too slow to spread the civilization mission and gain strength, or I will be promoted to the strength that is enough to fight these giants at one time, so as to protect the fire of the galaxy civilization!"

"Don't think about that kind of good thing, it's impossible. The existence of the tree of civilization itself has the most natural system of rules. Those who have the opportunity are on the right path. What's more, the strength of the exotic civilization that can come to this continent is definitely impossible to surpass the powerhouses on the Tianlan continent too much, this is the law of exotic space, and no civilization can break it. The reason why the galaxy civilization has been able to survive in the galaxy for millions of years is because it has the most reasonable rules and principles that all races think,"

"Prosperity, democracy, civilization, harmony, freedom, equality, justice, rule of law, patriotism, dedication, integrity, friendliness......" Song Xiaopeng blurted out.

"Yes!" the vicissitudes of life in the Tree of Civilization added a little more seriousness.
