Global Cataclysm: Get level 3 civilization at the start

Li Chen deliberately checked the description of this super energy barrier.

But it was as he expected.

Although the star shelter is upgraded, it comes with a super energy barrier.

And this super energy barrier is still able to resist mental and physical attacks, a double defense barrier.

But limited by the level of the star shelter itself, the defense capability of this super energy barrier is not particularly strong.

If you have to make a quantitative comparison.

Its defensive ability can probably only resist it.

A spiritual or physical attack launched by an evolutionary whose genetic evolution level is around the peak of level seven.

If the strength is higher than the peak of the seventh level of genetic evolution, basically the effect of defense will be greatly reduced.

Of course, continue to upgrade the level of the star shelter.

This super energy barrier will be further strengthened.

In general, Li Chen is quite satisfied with the upgrade effect.

The reason why he is so anxious to upgrade the level of the star shelter.

The reason is naturally very simple.

He has seen those incomparably powerful Star Destroyer motherships in outer space more than once.

Even the "Dyson group" of the shadow organization could not effectively resist that kind of attack.

Although at present, the defense of the star shelter can already resist all weapon attacks on the earth.

But those hot weapons on the earth are definitely not the same as alien technology.

In order to avoid any unexpected situation, Li Chen must consider various possibilities.

After all, the total population of today's star refuges is calculated in billions...

Thinking about it, Li Chen reopened the synthesis panel.

Consumed 55000 trillion evolutionary energy and 1000 million first-generation eighth-order energy crystal nuclei.

Synthesize a [Star Refuge Upgrade and Enhance Blueprint] again.

After successfully synthesizing the drawings, Li Chen thought about it.

"This kind of blueprint can unconditionally increase the level of the star shelter to 5 stars...then just make another one!"

Thinking that he synthesized another upgrade blueprint.

After the synthesis was completed, Li Chen opened the holographic map to check it out.

The overall situation of the current star shelter.

After upgrading to three stars, the area of ​​the star shelter becomes very, very huge.

Now it has truly surpassed the entire area of ​​Donghai City.

It's like a super underground city.

Its east-west length exceeds 360 kilometers.

The north-south width has also reached about 280 kilometers.

The total population capacity can accommodate about 2000 million people while maintaining the healthy operation of a city.

The maximum population limit is 500 million.

"I don't know how much this capacity will increase if I continue to upgrade to four stars..."

Li Chen thought to himself, and immediately used another upgrade blueprint without hesitation.

Upgrade the star shelter, plus the defense of the super canopy covering the entire Y province.

It can be said that it is like a paradise.

The safety factor has risen sharply.

As Li Chen once again chose to upgrade the star shelter.

Noah's notification tone also followed and resounded through every corner of the entire shelter.

At this time, most of the survivors in the entire star refuge have not recovered from the surprise.

I heard Noah say again that the star shelter is about to start upgrading.

These commanders, persons in charge, and ordinary residents were all dumbfounded and astonished.

"Upgrade again? What kind of operation is this!"

"The upgrade has just been completed, and the defense and area have been greatly improved! Didn't expect to continue to upgrade?"

"Our star refuge is going to be built into a super underground city, right?"

"Super underground city... I'm really looking forward to it!"

"Yes, there is a super-canopy protection in the sky outside, and a super-powerful star shelter underground to provide us with stronger defense protection! We no longer need to worry about safety issues..."

"These are operations in response to alien invasion?"

"..."

Following Li Chen's second star-rated shelter upgrade operation.

This time, even ordinary survivors.

Finally began to realize that things are not simple.

Amidst the speculations of everyone, time passed by every minute.

Soon, the star shelter was upgraded again.

It was the same as what Li Chen judged.

This time, the overall defense capability of the star shelter has of course been increased several times.

The average thickness of the shelter alone has reached 300 meters.

Moreover, the material has been further upgraded, using a super synthetic metal with stronger defensive capabilities.

The area has also increased further than when it was three-star.

The shape of the entire refuge has not changed much.

But the length from east to west exceeds [-] kilometers, and the width from north to south also reaches about [-] kilometers.

This makes the entire star shelter, the total population capacity.

It is ensuring that the entire shelter can operate healthily, that is, there is sufficient food, sufficient jobs, sufficient energy supply, and so on.

All aspects are maintained within a very reasonable and normal level of population capacity.

Probably around 4000 million people.

If overloading is allowed, the upper limit of the total population can reach about 6000 million.

Of course, the most important thing is that after upgrading to four stars, the strength of the super energy barrier that comes with the star shelter has been further strengthened.

Not only is there an extra layer compared to the original single-layer double-defense super energy barrier.

In other words, it is equivalent to having two layers of barriers that can resist mental and physical attacks at the same time.

Moreover, the defensive power of this super energy barrier has reached a level where it can easily resist the attacks of people with the eighth-level peak ability of genetic evolution.

"The area of ​​the four-star refuge is already equivalent to the size of two cities."

"The defensive ability has also been further strengthened..."

"The upgrade blueprint for Lv1 can be used again to directly upgrade it to a five-star level!"

"The other thing is that I don't know, can the defense of the super energy barrier be strengthened with this unlimited blueprint?"

Li Chen thought silently in his heart.

Since this kind of blueprint is called [Star Shelter Upgrade and Strengthen Blueprint].

This means it can be used for more than just upgrading star shelters.

It can also be used to directly strengthen the various functions of the star shelter...

Thinking of this, Li Chen decided to try it first.

"Noah! Can you see the super energy barrier that can strengthen the current star shelter?"

Li Chen issued an order in his mind.

Immediately got a positive answer from Noah.

[Answer the host, yes]

【This 'Star Refuge Upgrade and Strengthen Blueprint' was created specifically for this purpose! 】

Noah's words moved Li Chen's heart slightly.

But he didn't ask right away.

Instead he nodded.

Using the strengthening blueprint in his hand, he strengthened the super energy barrier.

Chapter 8 and six five stars

In fact, Li Chen had already noticed some details before.

[Star Refuge Upgrade and Enhance Blueprint] The appearance of this thing has long caused him to think.

Since this thing can be mass-produced.

Moreover, higher-level enhanced blueprints can also be synthesized.

It means that the demand is more than once.

If it is just a one-time consumable, there is no need to repeat the synthesis at all.

Because Li Chen only has one star shelter.

The reason why these things can be synthesized in batches is created.

There is only one possibility.

That is the star refuge, in fact, there is not only one.

Of course, at the beginning, this idea just flashed through Li Chen's mind.

Until Noah answered its question just now, he mentioned the statement that "this kind of thing is specially created for star shelters".

At this moment, Li Chen finally realized.

Your own judgment is correct.

There is indeed more than one star refuge!

And at this moment, just as these thoughts kept flashing through his mind.

Noah's reminder sound also followed.

【Ding!Strengthen success! 】

[The current level of the super energy barrier of the star refuge has been increased, which can defend against the physical or mental attacks of the ninth-level peak evolutionary of genetic evolution! 】

This trick is indeed feasible!

Hearing Noah's prompt in his mind.

Li Chen was overjoyed.

After being strengthened, the super energy barrier can perfectly defend against the strong at the peak of the ninth level of genetic evolution.

Whether it is a physical or mental attack launched against the star shelter.

If you continue to upgrade the star shelter or continue to strengthen it.

This effect will be further enhanced!

"Basically... it can be regarded as solving some worries!"
