The Orion spiral arm is one of the four major arms of the Milky Way.

It is divided into ten star regions, and each star region was once covered with countless civilizations, large and small.

And with the passage of time, some of these civilizations were conquered, annexed or completely destroyed by other civilizations.

Another part of civilizations rose rapidly through conquest, plunder, embezzlement and mergers, etc., and became the overlord level civilizations of their respective star regions, or even several star regions.

Today, the civilizations on the spiral arm of Orion have more or less discovered a secret.

When they grow to the fourth-level peak civilization, they begin to realize that they need to further improve their own civilization level to reach the level of the fifth-level civilization.

You need to get a special item called "key".

On the surface, it is something called the Secret Code of Civilization.

It looks like a book.

The key is not complete, it is a combination of the secret books of civilization.

This also means that any civilization that wants to obtain the complete key must conquer other civilizations.

Furthermore, they obtained the secret tome of civilization in their hands, or... key fragments.

Only by collecting all the key fragments can they achieve their goal, synthesize keys, and then advance to a fifth-level civilization.

Due to such a discovery, the relationship between the various civilizations that have been competing for tens of millions of years due to the competition for energy resources, territory technology, etc., has become even more tense.

Even many civilizations fought each other, conquered and conquered each other...

This situation does not just happen on the Orion spiral arm.

The spiral arms adjacent to the Orion spiral arm are the Perseid spiral arm and the 3KPC arm respectively.

They lie to the left of Orion's spiral arm, one of the outermost members of the Milky Way's spiral arm.

On the right side of Orion's spiral arm, there are Carina spiral arm and Sagittarius spiral arm.

In addition to these relatively large spiral arms, there are actually many smaller spiral arms within the entire Milky Way.

Their area is relatively small, and their length is often only about 10,000 to 20,000 light-years.

And the number of star systems in the region is not as large as those of those large spiral arms.

So it is often ignored by people.

But in fact, above these small spiral arms, there are also advanced civilizations.

Third-level civilizations and even fourth-level civilizations also exist.

At this very moment, the half-orc civilization is on the frontier and staring at the shooter civilization.

Similar things are also happening on the Perseus spiral arm and the 3,000 parsec arm next door.

And farther away, the Sagittarius spiral arm and the Carina spiral arm are nearly 10,000 light-years away.

Something similar is happening over there.

Some powerful civilizations are absorbing other civilizations in an alliance.

Because they also realized that the next competitors, with a high probability, are civilizations from other spiral arms.

Faced with this situation, group cooperation is the most effective way to deal with it. It is even more difficult for any single civilization to fight against the entire spiral arm.

Of course, similar situations don't just happen in the Milky Way.

The same thing is happening in other galaxies as well.

In order to compete for the key fragments to upgrade to the fifth-level civilization, those fourth-level civilizations and third-level civilizations are attacking each other.

It's like a well-designed game.

Those low-level civilizations can only become victims of the competition of high-level civilizations.

And in the wider universe...

In greater realms far beyond the Milky Way, beyond the Virgo supercluster, etc.

Games belonging to higher levels of civilization are also taking place.

The competition seems to never stop...

It's just that the competition between higher-level civilizations is far from what the low-level civilizations in the small galaxy can see and perceive.

Li Chen woke up from his sleep and found himself covered in cold sweat.

The strange thing is that he can't remember the content of the nightmare he had.

I just feel my heart beating violently.

The whole person has a kind of coldness and lingering fear like falling into an ice cave.

It was as if in a dream, something terrible happened.

This sudden feeling made Li Chen uneasy for no reason.

"Commander, what's wrong with you?"

Xu Ruoxi happened to come over to deliver breakfast to Li Chen, seeing his pale face, she couldn't help asking about the situation in doubt.

"nothing…"

"what time is it now?"

Li Chen shook his head, put on his clothes, got out of bed and checked the time.

"Commander, it's only eight o'clock in the morning."

"This is a breakfast specially made for you by the kitchen. I said that you are too tired recently to replenish you."

Xu Ruoxi replied.

Hearing this, Li Chen turned his head and looked at the breakfast in the other party's hand.

I was a little speechless for a while.

"Don't do this next time, I am no different from you, there is no need for special treatment."

Li Chen went to wash up while talking.

Xu Ruoxi behind him reminded: "All the Star Destroyer Motherships have been upgraded, Commander."

Li Chen, who was brushing his teeth, was slightly taken aback when he heard this.

"Oh, I see."

"These guys are quite efficient..."

He muttered to himself.

That last sentence refers, of course, to the scientists of the Seventh Civilization.

You must know that in addition to the one million Star Destroyer battle group led by Li Chen himself, he later mobilized about 50 million battle groups from the rear.

So many Star Destroyer motherships need to be upgraded and refitted with fourth-generation curvature engines.

At the same time, weapons and defense systems must be upgraded.

Such a workload can be imagined.

The order was issued only two days ago.

Today, the seventh civilization has completely handled everything for him.

This kind of work efficiency can be described as a miracle.

"The opponents of the seventh civilization are all other four-level peak civilizations. According to their own words, these are basic crafts."

"Without such a strong support system, they would have no way to guarantee the loss of frontline troops in a timely manner in the event of a war..."

Xu Ruoxi smiled and explained.

Li Chen wiped his face with a towel, and nodded upon hearing this.

"Let's go and see our new Star Destroyer!"

He casually took a piece of bread from the tray in Xu Ruoxi's hand, took a casual bite and put it back.

"Ordinary food...is becoming less and less attractive to me."

While chewing the food, Li Chen was talking to himself.

"Then Commander, these foods...?"

"Don't eat."

Li Chen waved his hand, took out a bottle of high-concentration energy liquid, unscrewed it, and gulped it down.

After drying up the whole bottle of energy liquid, I immediately felt refreshed and full of energy.

The fatigue from continuous work has completely disappeared, and he feels that he can go without eating, drinking or sleeping for another month.
