The earth is as small as dust in the universe.

Beyond the Earth, there is the solar system.

The solar system is located on the Orion spiral arm of the Milky Way.

There are 200 billion stars like the Sun in the Milky Way.

Larger than the Milky Way is the Local Group of Galaxies.

There are more than 50 galaxies like the Milky Way in this group.

The local group of galaxies is 10 million light-years in diameter, which means that it would take 10 million years to travel through the entire group at the speed of light.

This is not the end, and larger than the local group of galaxies is the Virgo Supercluster.

Larger than the Virgo Supercluster is the Pisces-Cetus Supercluster complex, which scales 1 billion light-years.

The Earth is just a speck of dust in the universe.

And human beings living on "dust" are in the first stage of civilization, planetary civilization.

The second level of civilization is the "stellar civilization".

Stellar civilizations can use the energy of stars as a source of energy to explore space, and warp engines to explore other star systems.

Usually, the development of civilization is at this level, and individuals are strengthened by implanting smart chips and other methods.

The third level of civilization is the "galactic civilization".

Civilizations that reach this level can use wormholes for interstellar voyages, populations are able to leave native stars, survive in other star systems, understand and exploit black holes, and begin to explore multidimensional space.

If one day, when human beings develop to the point where they can visit every corner of the galaxy and fly out of the galaxy to explore other galaxies, they will reach the third level of civilization.

However, what is frightening is that the information revealed by Rahu shows that he is from the fourth level of civilization, that is, the "super galaxy civilization" that is higher than the "galaxy civilization".

In the study of cosmic sociology, it is generally believed that the "supergalactic civilization" belongs to the most aggressive stage in the development stage of civilization.

Civilizations at this stage, in order to plunder resources, will not hesitate to launch interstellar wars.

Moreover, although the science and technology at this stage are advanced, if there are several technological explosions in the low-level civilization, it is entirely possible to catch up with the scientific and technological level of the "super-galactic civilization" within a few centuries.

Even if the level of science and technology is not surpassed, as long as the technological level of the low-level civilization is close to that of the "super galaxy civilization", it can leave the original galaxy, continue the fire of civilization, and spread the flames of war to all corners of the universe.

Therefore, the "super-galactic civilization" belongs to a stage that can be surpassed by a low-level civilization at any time.

For this reason, the "super-galactic civilization" will not hesitate to launch an interstellar war to eliminate the low-level civilization in the embryonic stage.

Prevent low-level civilizations from threatening them after the tech explosion.

Unfortunately, human civilization is a primary civilization in the stage of the big bang of science and technology.

Therefore, those who have learned about the sociology of the universe at the scene immediately thought of a lot of key information when they heard Rahu say the words "fourth-level civilization".

"What is the reason for the four-dimensional collision between the Earth and the Star Beast World?" Dr. Anlan asked aloud.

"Isn't that simple? Of course, it is my Palese civilization that is eliminating you low-level civilizations, and you are very close to the four-dimensional distance of the Star Beast World, so casually smashing your two worlds together and destroying two low-level civilizations at once, to explain it in your words, is to get twice the result with half the effort. Rahu replied.

When everyone heard this answer, a moment of shock flashed in their hearts.

The earth and the Star Beast World collided in four dimensions, and it turned out that the higher civilization was clearing the lower civilization.

When he heard this secret, Fang Yuan suddenly discovered that the fate of the earth was far more tortuous than he imagined.

If this information is true, it means that before the spatial rift appeared, the Earth had been discovered by the Palese civilization.

"What does Palese mean in your civilization?" Dr. Anlan continued to ask.

"Soul Descends." Rahu replied.

"So, the real name of your civilization is Soul Advent Civilization." Dr. Anlan repeated a few words.

"Soul Arrival? I think it's called soul parasitism, right? Or maybe it's more appropriate to call it energy parasitism. Fang Yuan said sarcastically.

"Whatever you say, you have long been discovered by my civilization, and your only hope for survival is to ensure the safety of my life in exchange for your chance to become a colony." Rahu uttered threatening words.

"Where is the advent civilization in the universe?" Dr. Anlan asked again.

"Not in your galaxy, far, far away, more than 100,000 light years, your observed cosmic star map is too rough, if you have to have an answer, in my civilization, the home galaxy is called Divine Descent." Rahu replied.

"So, your civilization is an extreme cleaner?" Dr. Anlan continued to ask questions.

"It's not appropriate for the washer to be clear, because we're really just sweeping the garbage, not extreme at all. Do you understand? I clean up your garbage just like you clean up cockroaches. According to your logic, cockroaches should also call you extreme cleaners. Rahu corrected.

"How did the advent civilization discover the earth? More than 100,000 light-years away, it won't be so easy for you to spot. The Milky Way is 100,000 light-years in diameter and has 200 billion stars. Dr. Anlan asked.

For the universe, the earth is so small, like a speck of dust.

Just as humans don't care about the dust in the corners, it is not so easy for high-level civilizations to find the sun in 200 billion stars, let alone the earth.

What's more, according to Rahu, the advent civilization is 100,000 light years away, so the advent civilization is not in the galaxy at all.

If what Rahu said is true, the advent civilization is a super-galactic civilization, then the advent civilization controls at least one galaxy.

If the home galaxy of civilization had been the Milky Way, humanity would have been doomed long ago.

From this it can be seen that the advent civilization is not in the galaxy.

"I don't know about this, maybe you were unlucky, and you happened to be discovered."

As for the question of how the advent civilization discovered the earth, Rahu did not give a definite answer.

"Where is the planet where the star beast is located?"

"More than 1,000 light-years away from you, if there is no four-dimensional collision, it is a place that you will never be able to reach in your lifetime." Rahu replied.

All afternoon, Fang Yuan's head was buzzing.

Because every piece of information that comes out of Rahu's mouth is explosive, and every one of them may lead to a possible catastrophe that will destroy human civilization.

The Star Beast World is a thousand light-years away from Earth, and the advent civilization is outside the galaxy.

In the eyes of the advent civilization, the earth is like a cockroach in the eyes of humans, a group of creatures that should be cleansed.

Fang Yuan felt that his breathing had become heavy, and he stood outside the corridor and took a few deep breaths to calm his emotions.
