The overall length of the Orion Arm even exceeds the radius of the Milky Way.

That is more than 50,000 light-years.

Because the spiral arms of the Milky Way don't go straight.

They are a kind of barred spiral extending from the core region of the Milky Way.

It is equivalent to a "satellite" in the core area of ​​the Milky Way.

Therefore, the Orion spiral arm according to the degree of concentration of stars.

And the distance close to the core region of the Milky Way.

It is divided into ten different areas numbered 1~10.

There are one or more very powerful cosmic civilizations in each region.

These powerful cosmic civilizations control areas with a diameter of 6,000 to 10,000 light-years.

They are the representatives of the peak civilization on the spiral arm of Orion.

If within the Orion spiral arm, the ranking among various cosmic civilizations is calculated according to the number of the ruled area.

The area closest to the core of the Milky Way is the first area.

That is, the comprehensive strength ranks first.

In addition, the region that is the second closest to the core of the Milky Way belongs to the second region.

Then their comprehensive strength ranks second.

and so on.

…

According to Noah.

Noah civilization as a third-level cosmic civilization.

And the Pulitzer Civilization Empire.

These two civilizations are actually nothing in the entire Orion arm.

They are also located in the tenth area of ​​Orion's spiral arm.

That is, the outermost area of ​​the Orion arm.

It's like a "backcountry".

It is the furthest from the core region of the Milky Way.

If you use countries or cities on the earth as an example.

The tenth area of ​​the Orion Arm is not even an inland province or a suburb.

It is an area where the old and the young are poor.

It is a subordinate county, even a township, tens of hundreds of kilometers away from the urban area.

…

Of course, even though it sounds like it at first glance.

It seems that Noah said that the civilization within Orion's arms is already very special.

What the first region, ranked first.

The second area, ranked second blah blah blah.

But in fact, Li Chen is very clear that it is outside the spiral arm of Orion.

There are also higher-level civilizations that suppress these ten sub-advanced civilizations within Orion's arm.

After all, the entire Orion Arm is just a part of the Milky Way.

In addition to the Orion spiral arm, there are several other main spiral arms.

The civilization on the main spiral arm is the real developed cosmic civilization, which belongs to the high-level cosmic civilization.

Take the countries on the earth as an example.

The civilization in the central region of the Milky Way is the most developed and powerful country in the world today.

The cosmic civilizations on the main spiral arm are countries with large size, relatively developed economy, strong military strength, and certain independent scientific research capabilities.

The secondary spiral arms, such as the civilizations on the Orion arm, are more countries that have just stepped into modernization.

The vast majority of them belong to the "third world countries".

As for Earth civilization.

Putting it in the Orion arm should belong to the low-level civilization among the low-level civilizations.

In other words, it can be regarded as the pinnacle of primitive planetary civilization.

A low-level civilization that is about to approach the civilization of the universe...

The solar system where the civilization of the earth is located.

It happens to be in the tenth area of ​​the Orion Arm.

"Noah, if you say that... isn't the earth and your Noah civilization and Pulitzer civilization still in the same area?"

"Everyone is the aborigine of the tenth sector of Orion's spiral arm!"

Li Chen listened.

After hearing Noah explain so much.

Finally, there is one thing that I can hear more clearly.

Earth and Noah Civilization, Pulitzer Civilization.

In fact, let alone the entire galaxy.

Even if it is placed in the Orion spiral arm.

That also belongs to the representative of labels such as "backward", "poverty", and "barren".

[Answer the host, yes. 】

[We are actually neighbors. 】

Noah responded.

"Your neighbor is a bit far away..."

"By the way, Noah, what is the diameter of the tenth area of ​​Orion's spiral arm?"

Li Chen asked curiously.

[Answer the host, the No. 10 area of ​​Orion's spiral arm is the third largest area within the entire Orion's spiral arm. 】

[If it is regarded as a circle, its diameter is about 9656 light-years. 】

The diameter of a region is more than 9,600 light-years.

According to the technological level of Noah Civilization or Pulitzer Civilization.

Their spaceship wants to cross this area.

Fly from east to west.

At least it will take more than two hundred days.

But in fact, Noah has already said it before.

This is the sailing speed under the ideal state, which can only be achieved.

In reality, no matter whether it is the Noah civilization or the Pulit civilization.

None of their spaceships are possible.

Sailing at this speed at all is too long.

So really want to span this 10th district, from the east to the west.

Whether the energy of the spacecraft can support them to do this is not discussed for the time being.

It is certain that the time consumed will be more than the theoretical value.

"Then the area of ​​this area is not small..."

After listening to Noah's answer, Li Chen sighed.

[Yes host, I didn't express clearly before, I'm really sorry, this is what I want to say now. 】

[The tenth area of ​​Orion's spiral arm is divided into six different 'community streets'. 】

[The strength level is also expressed according to the serial number, 1~6 community streets, the higher the number, the stronger the strength. 】

[The solar system where you are currently host is located in the weakest community No. 6 street. This community is the largest among the six major communities in the tenth region, with a diameter of 1,800 light-years. 】

[It is temporarily unowned. 】

[The remaining five regions have been controlled by various civilizations. 】

[Our Noah civilization controls the No. 4 community street, and the Pulitzer civilization controls the No. 5 community street. 】

Noah further explained.

Now, Li Chen finally understood why Noah wanted to apologize to himself.

Such a large area.

There are thousands of star systems in it, and there are many, many civilizations.

As for the tenth area of ​​Orion's spiral arm, there are more detailed areas.

If you compare the Orion spiral arm to a city.

Then these ten areas are the different districts and counties of the city.

And each district and county is divided into a certain street, a certain community, and so on.

Like Noah Civilization and Pulitzer Civilization.

Such a third-level cosmic civilization dare not say that he is the ruler of the tenth district.

Because their two civilizations are only ranked fourth and fifth here.

Some areas are controlled by one or more civilizations.

And some areas are in an unowned state.

As Noah said before, the "galaxy" where the solar system is located is in a state of no owner.

What people actually want to express is.

The Orion spiral arm of the Milky Way, the sixth community street in the tenth area is currently in a state of no one.

After understanding everything.

Li Chen's question returned to the original question.

So, if I want to evolve a star shelter now.

Who should I go to apply for the record?
