The evolution level of the star shelter has been raised to 21 stars.

The total area expanded to 90 million square kilometers.

At the same time, the upper limit of the total population capacity has also been raised to 45 billion, and the maximum population can accommodate 60 billion.

In addition, it is not surprising that the overall defense of the shelter has been fully improved.

The strength of armor defense alone is enough to withstand the bombardment of energy cannons with an energy intensity of 350.

And the time it can withstand continuous bombing has also increased significantly...

Basically, most of the next threats can be dealt with.

But this is not what Li Chen wants.

Defense alone is not enough.

The level of weapons and equipment must also be raised accordingly.

And the levels that these weapons and equipment can be developed.

It is also strongly related to the evolution level of the star refuge itself.

Therefore, Li Chen still has to continue to evolve the level of the star shelter.

Thinking about it, he started the second evolution of the star shelter without hesitation.

【Ding! Congratulations on evolving the star shelter Lv22 (twenty-two stars) to star shelter Lv23! 】

…

【Ding! Congratulations on evolving the star shelter Lv24 (twenty-two stars) to star shelter Lv25! 】

…

【Ding! congratulations…】

…

Li Chen raised the level of the star shelter to level 30 in one breath.

Directly evolve the star shelter to thirty stars!

The star refuge at this moment.

The total area already covers the entire earth.

Even the area of ​​the star refuge is slightly larger than the surface area of ​​the earth.

The Earth's surface area is approximately 510 million square kilometers.

At this moment, the total area of ​​the thirty-star refuges has reached 650 million square kilometers.

If the star shelter is expanded into a planet.

Then its current volume has exceeded that of the earth.

Of course, not that exaggerated.

The length and width of the star shelter reached the level of the planet.

But its altitude is only about 500 kilometers.

It's not so much a planet.

Rather, it is more appropriate to say that it is a planet-level super-giant spaceship.

[Host, you have upgraded the star shelter to 30 stars, and the current civilization level has reached level 2. 】

[The Big Data Center of the Cosmos Alliance automatically sent you an invitation for certification. 】

Noah's voice sounded in his mind.

This made Li Chen calm down a little.

Otherwise, he will continue to evolve the star shelter.

Hearing Noah's words, Li Chen remembered what the other party said before, about the rules about hiding the level of civilization.

Li Chen basically shook his head and rejected Noah without even thinking about it.

"No certification, no invitation."

"It doesn't need to be said, Noah."

"It's the same next time, whether it's a third-level civilization or a fourth-level civilization."

"In short, just ignore as many certification invitations as there are from the big data center of the Cosmos Alliance!"

After waving his hand and finishing speaking, Li Chen opened the property panel of the Star Refuge.

After evolving to thirty stars.

The overall defense of the star shelter can only be described as terror.

Its overall strength is enough to resist the damage of energy cannons with an energy intensity of about 800.

In other words, even the most advanced Star Destroyer Mothership of the Pulitzer Civilization Empire.

Don't even think about threatening the overall existence of the star refuge.

Because their attacks couldn't break through the barrier defense of the star shelter.

Not to mention, there is a super powerful energy barrier protection outside the star shelter.

In addition, the thirty-star star sanctuary.

The upper limit of total population capacity has reached 150 billion.

If the limit is accommodated, the total population limit will reach 200 billion.

But as a price, Li Chen consumed a lot of energy resources in this wave.

He checked it out.

The energy crystal nucleus and evolution energy obtained from Silver Fist.

There are other materials and so on.

Basically, it has gone through a series of operations such as its own evolution and the evolution of the star shelter.

About half of it was removed.

This is the result of Li Chen's efforts to save flowers as much as possible.

"Master, we have noticed a huge change in the star shelter, you... are you evolving the star shelter again?"

While Li Chen was checking the attribute panel, commanders such as Xu Ruoxi, Dang Zhongcheng, Nougatang, Mo Yue, etc. came to the door one after another.

They all stared at Li Chen with big eyes and small eyes, their faces full of surprise and uncertainty.

When the star refuge evolved to twenty-one stars, they had already noticed it.

But no one paid much attention.

After all, this kind of thing is used to it.

But with the continuous evolution of the star shelter.

The level is constantly improving.

The area is getting bigger and bigger.

There are more and more functional areas, which are subdivided into more and more details.

These commanders became more and more shocked.

The total area of ​​the star shelter has expanded by about ten times in one breath!

How does this keep them from feeling magical? Not shocked?

"Well, I just casually evolved the level of the star shelter."

"Now we are preparing to strengthen other firepower systems."

"What's the matter?"

Li Chen turned his head to look at the crowd, and asked in doubt.

Just evolve...

Look, is this what people say?

Casually, turning a shelter into a "planet"?

"There is nothing wrong with the matter, it is the star refuge, and now it can really represent the entire civilization of the earth."

Xu Ruoxi replied dumbfounded.

Seeing the weird faces of these guys, Li Chen frowned.

"Have you nothing to do?"

"Hurry up and do your own thing, don't talk about it here."

"By the way, Xu Ruoxi, go and distribute this month's bonus to each of the fighters."

Li Chen remembered this matter and reminded.

Hearing this, Xu Ruoxi was stunned for a moment.

"bonus?"

"Commander, what bonus?"

Xu Ruoxi asked suspiciously.

The others also looked at Li Chen with puzzled faces.

Everyone thought that Li Chengui was busy with personnel and confused things up.

"In addition to the fixed monthly salary, they are given an additional bonus. From this month, everyone will have a share, and so will you."

"For the specific bonus amount, you go to Lao Chen and ask him for a form. He knows how to deal with it."

Li Chen waved his hand and didn't want to say more.

Hearing what Li Chen said, everyone understood.

Immediately, everyone's faces became joyful.

"We'll do it right away!"

Xu Ruoxi didn't talk nonsense, and quickly took the lead, turned around and left.

At this time, Noah's voice sounded in his mind.

[Host, you are so generous, don't you worry about the lack of energy? 】

Noah reminded.

"The boss eats meat, so why should the employees drink some soup? If you let people eat bones, ghosts will help you with your work!"

"Can you understand this truth? Noah?"

Li Chen asked back with a half-smile.
