The border war of the Pulitean Civilization Empire was shrouded in a layer of fog and shadow.

It is suspected that there has been a fourth-level civilization involved.

As a result, until the full half month after the end of the war.

Whether it's the Gaia civilization or the Pulitzer civilization, or the Noah civilization, or the Valoran civilization, or the Prome civilization.

Everyone kept secret about this matter and this war.

The five major third-level civilizations are shrouded in an emotional atmosphere of panic from top to bottom.

If it is really targeted by the fourth-level civilization.

They probably can't do anything but sit and wait.

Of course, neither are these imperial civilizations, they really do nothing.

During the half month of silence.

Naturally, they are also constantly sending spies to collect intelligence.

Constantly trying to obtain relevant information from various channels, and at the same time continuously strengthening its own combat effectiveness.

A steady stream of energy resources were mined and sent to the empire's research institute.

It is used to develop more powerful and advanced science and technology for relevant scientists.

As for those civilizations with evolutionaries.

The high-level executives have consumed a lot of energy resources during this half month.

To strengthen and improve oneself.

Even if they are above 10,000 people and have a noble status, they are also afraid of death.

As long as he is alive, it means that he can still have a chance to make a comeback.

With their skills and means, they can create another civilization.

But if he was killed, then everything would be out of the question.

Therefore, the founders of these imperial civilizations are the highest talkers.

It is understandable that they have been trying to improve their life-saving ability in the past half a month.

And at this very moment.

The southern border of the Pulitean Civilization Empire.

Rock Fortress.

This place has been completely remodeled by Li Chen's star shelter, and upgraded into a bigger and stronger super fortress.

It became the first springboard for the earth civilization to extend its hand to the Pulit civilization.

During the period of more than half a month, the earth civilization mined at least tens of thousands of star systems in the vicinity.

Harvested a large wave of energy resources.

Using these energy resources, Li Chen raised the evolution level of the entire star shelter to eighty stars.

That is, after he completed the operation.

Li Chen received a new invitation message from the Big Data Cloud Computing Center of the Universe Alliance.

An invitation for Level 4 Civilization Certification.

"Noah, have we become a fourth-level civilization?"

Li Chen was very surprised.

Some even feel dreamy and unbelievable.

Why did it suddenly become a fourth-level cosmic civilization? They had just received an invitation from a third-level civilization.

It's been less than four months...

[Host, are you unhappy? 】

Today's Noah is a bit skinny, he immediately asked back after hearing Li Chen's question.

"Why are you happy? It's not about giving me money."

"The four-level civilization certification means that our civilization level has reached the entry standard for a four-level civilization."

"This also means that our comprehensive strength has already surpassed those third-level civilizations, right?"

"The pressure is even greater..."

Li Chen sighed, and opened his property panel to check.

【Star Shelter System】

[Binding 2]: None

[Number of genetic evolutions]: 20

[Evolution energy needed to upgrade a little]: 500 billion Beijing.

[Second Power - Small Universe] Seventh Sense: Level 1.

…

During these half a month, Li Chen has not been idle.

In addition to directing various tasks and upgrading the overall strength of the entire star shelter.

He himself had also evolved to the peak of level 20 by the way.

Now his attribute points are no longer known how many times it was before.

Even a fraction of the attribute can be killed in seconds, and once made him feel like a Megatron that cannot be crossed.

The powerful power also made Li Chen truly feel the vastness of the entire universe.

With a stronger desire to conquer.

Of course, it is impossible for the earth civilization to be upgraded to a fourth-level civilization because of the improvement of Li Chen's personal strength.

It is determined by the improvement of the overall strength of the earth civilization and the degree of development of civilization science and technology.

First of all, it is naturally a star refuge, and it is a matter of upgrading to 80 stars.

An eighty-star star sanctuary.

No matter in terms of size, population size or defense capabilities, etc.

They have all reached the late stage or even the peak level of the third-level civilization.

Now if the entire star refuge that is in an invisible state is directly revealed.

It will definitely scare anyone who sees it.

Because the star refuge at this moment has completely become a super super super super star destroyer mothership!

It is more than 150 million kilometers long.

The width also reached 98 million kilometers.

The altitude is nearly 80 million kilometers.

Such a volume can directly accommodate countless suns.

Therefore, the scale of the star refuge has reached the middle and late stages of the third-level civilization, or even the peak level.

In addition, because Li Chen dispatched a large number of mining transport ship formations, they returned to the sixth star field to mine resources.

By the way, one low-level civilization after another was incorporated.

This has led to the number of affiliated civilizations of the current earth civilization as many as 550.

The total population adds up to more than three trillion.

It means that the average population of each civilization has at least five or six billion.

This is the population size of the current earth civilization.

The explosion of population naturally brought sufficient labor force to the civilization of the earth.

Under the professional training of the star shelter.

The life forms of these civilizations that were carefully selected and left behind each have different talents and values.

Trillions of people are working together to develop earth civilization.

This effect is naturally needless to say, it is very prominent.

In addition, the technology, economy, military strength and so on of the earth civilization.

Also in this short period of more than half a month, we ushered in explosive growth.

Especially worth mentioning is the military strength.

The current star refuge has 580,000 third-generation star destroyer battle groups.

All are equipped with the second-generation curvature engine propulsion system, as well as the most advanced anti-stealth and stealth technology bonuses.

In addition, there is the most powerful firepower configuration.

This is enough to ensure that the civilization of the earth can fight in places far away from the mainland anytime and anywhere, and conquer countless civilizations!
