The increase in supplies and combat personnel shows that the production capacity of various resources in the star shelter is still steadily improving.
Not only can the consumption be covered, but also a little left over.
At the same time, more and more combatants are completing training to join active duty.
There are also more and more newly joined members who have become reservists.
This is a good thing for a star shelter.
But what Li Chen is curious about now is that the output power level of the example energy cannon reaches level 999, what kind of terrifying existence will that be.
One level is equivalent to the explosion power of a mushroom bomb with an equivalent of 1 billion tons.
Level 999, that is 999 billion tons.
Although the power of mushroom bombs does not increase exponentially with the increase in equivalent.
There is not a proportional relationship between the two.
But with such a terrifying equivalent, the impact of the explosion is also at the level of destruction.
Li Chen is sure that even the Star Destroyer, which is attacking the earth now, does not have such a high-level weapon system.
I just don't know, the three hundred most advanced Star Destroyer Motherships that rushed over recently.
Is there such a firepower configuration...
Thinking that there are more powerful enemies coming towards the earth.
It is possible that the star refuge in the future will need to directly face the Pulitzer civilization.
In an instant, Li Chen lost the happy thoughts he had just had.
At this moment he only felt Alexander on his shoulders.
Came back from contemplation.
Li Chen set his sights on the last attribute of the Star Refuge's attribute panel.
That is the latest unlocked function after the upgrade was completed just now.
Air circulates inside.
This function can ensure that the star shelter does not establish air circulation with the outside world.
Automatically generate enough oxygen.
It is used to maintain an environment suitable for the growth and survival of life forms inside the shelter.
in other words.
Even if the star refuge is not under the ground, but deep in the sea.
At an altitude of 10,000 meters.
Even in outer space.
In an environment completely isolated from the air.
As long as the "air circulation system" is turned on, people in the star shelter can carry out normal production and living activities.
There is no need to worry about death due to depletion of oxygen.
This is a very nice feature.
However, once this function is turned on, energy and water resources need to be continuously consumed.
Now Li Chen is most afraid of seeing these two descriptions.
The lack of energy in the star shelter last time left him with a psychological shadow.
I always feel that no matter how much energy I have, there will be a day when I will run out.
So at this moment, he felt that it was better not to verify the effect of this function for the time being.
Li Chen looked at his personal attribute panel.
Let Noah spend one-fifth of his entire net worth, which is half of all evolutionary energy and energy crystal nuclei.
Public storage account allocated to Star Vault.
The energy consumption of the upgraded star shelter will also increase.
It must be ensured that the last time the situation will not happen again.
After finishing all this, he turned off all the attribute panels, and performed the upgrade and evolution operation on the star shelter again.
There are also two Lv2 upgrade evolution blueprints on hand.
Li Chen raised the star shelter from six stars to eight stars in one breath.
Then check the attribute changes after the upgrade of the star shelter again.
Evolved to an eight-star star shelter.
The area has soared from the original 210,000 square kilometers to 660,000 square kilometers.
Basically, the entire province Y has been completely covered.
But this province is located at a depth of hundreds of meters underground.
The protection level has been improved after the upgrade and has become SS+, which can resist the attack of particle energy cannons with energy intensity level 8 and below.
In addition, the super energy barrier that comes with the star shelter.
Defense has improved again.
From the original, it can only defend against the physical or mental attacks of the evolutionists at the beginning of the tenth level of genetic evolution.
Up to now, it has been able to withstand the double attacks of the early evolutionists of the eleventh level.
This is the case when Li Chen did not strengthen this energy barrier alone.
With the effect of automatic growth of the star shelter.
And this super energy barrier can be strengthened individually.
While the protection ability is greatly improved.
The total population capacity of the eight-star refuge has also been greatly increased.
At the current level, under a healthy state, the normal population that can be accommodated is about 800 million.
It can accommodate a maximum of 1 billion people living inside at the same time.
In addition, Li Chen also noticed a situation.
That is after the upgrade of the star shelter.
He found that the depths of star shelters are also increasing.
This is equivalent to the fact that the star shelter has been sinking.
Perhaps it is because of the increase in volume and the substantial increase in quality.
But Li Chen always felt that this might not be a good thing.
"Noah, I feel like the star shelter is sinking, it should be fine, right?"
"After all, there is magma under the ground..."
Li Chen asked Noah worriedly in his mind.
The interior of the earth is actually extremely dangerous. In addition to magma, there are various unpredictable dangers deep in the mantle.
Such as ultra-high pressure, and ultra-high temperature and so on.
Although the radius of the earth has reached thousands of kilometers.
Now they are only a few thousand meters underground.
But Li Chen still felt uneasy.
He worries that if this continues, the star shelter will eventually "sink" under the ground.
[Answer the host, please don't worry. 】
[With the current protection level of the star shelter, even if the entire earth explodes, the impact on the interior of the shelter will be very limited. 】
[What's more, your star refuge may not always remain underground. 】
Noah replied.
There is something intriguing about its last sentence.
It seems to mean something.
Li Chen noticed this immediately.
"Noah, what do you mean?"
"What does it mean that a star refuge may not always remain underground?"
Li Chen hurriedly asked curiously.
He felt that there was something in Noah's words.
[It means literally, host. 】
[No one stipulated that the star shelter must be underground. 】
【Didn't you see it? The Shadow Organization established the refuge in outer space. 】
Noah explained.
From its answer, Li Chen finally heard something.
According to Noah's meaning.
In the future, I can also turn the star refuge into a space refuge like the shadow organization.
The existence that makes it suspend in the air?
Just when Li Chen wanted to continue asking questions.
Suddenly, a hurried report sounded in Li Chen's ears.
"Total Commander, we just received news that a group of terrorists kidnapped about 300,000 survivors and offered us a redemption condition..."
