Li Chen carried out the upgrade operation with ease.
At the same time, the incomparably powerful mental power spread out in an instant.
It completely enveloped the entire province of Y and even the entire Dragon Kingdom.
According to previous experience, the upgrade process of the entire star shelter will take a certain amount of time.
During this period of time, it is up to you to be responsible for the defense, and be alert to the possible attacks of the enemy!
As the upgrade operation proceeds.
In an instant, the energy supply of the entire refuge was cut off.
Everything has come to a standstill.
Whether it is a fully automatic production line or a manual production line.
Or all other production activities and life activities.
All are affected.
This sudden scene immediately made the entire star refuge restless.
Puzzled, people asked what happened.
"Noah, explain to them."
Li Chen calmly ordered in his mind.
It is not the first time that Noah has done this kind of thing.
Of course, it is also familiar with the road.
So soon, under Noah's explanation and reassurance, a large number of ordinary residents, commanders and people in charge at all levels became quiet.
"Is our star shelter going to start upgrading again?"
"The strong artificial intelligence just now has been said, and it is going to be upgraded and expanded!"
"The alien civilization is really powerful...but Commander Li Chen is even more powerful, and he can command such a high-level civilization!"
"Now our star shelter will become more advanced and powerful? It's really great!"
"Noah said that after the upgrade, our shelter will have stronger defenses, a wider area, and a larger population that can accommodate... In short, this is a great thing!"
"..."
Countless ordinary survivors were smiling and full of anticipation.
Discussed this matter very enthusiastically.
The other commanders, on the other hand, saw it more thoroughly than they did.
"Improving defense and firepower is to meet the next challenge..."
"Well, the situation in the sky seems not to be optimistic. Although I can't see what's in the outer space above a thousand kilometers, and I don't know the outcome of the battle... But I can hear and see it. Explosion!"
"I also sensed those movements. I can only say that aliens may invade the earth at any time!"
"Get ready for battle! Everyone! You can't let the Commander-in-Chief face those enemies alone!"
"Everyone give me a good training! You must master more advanced fighting skills!"
"..."
Amidst the discussions of countless people, time passed by every minute.
Finally, after a long wait of three hours.
Suddenly, the survivors in the shelter found that they seemed to be rapidly moving away from everything they were familiar with.
It was an amazing feeling.
As if standing on the ground, moving forward or backward quickly.
At the same time, the surrounding scenes are also changing.
The originally spacious and vast space has become even more spacious and vast.
The height of the ceiling from the ground has also become higher.
Even, those people and things that were less than a hundred meters away from him just now.
Suddenly it becomes thousands or even thousands of meters away.
"It's almost finished! The upgrade operation of the star shelter!"
"Oh **** ho **** ho... The area has become much larger! I actually 'flyed' so far all of a sudden!"
"My dear, how many times has this area increased?"
"Is the defense stronger? We live and work here, so we don't need to worry about being attacked by aliens, right!"
"..."
Many of the people here have joined the star refuge since the catastrophe broke out in the last days.
Counting them, they have gone through the process of upgrading and strengthening the star shelter twice.
However, for the first time, it is mainly to upgrade the defense of the star shelter as a whole.
So everyone didn't feel much.
But for the second time, the area of the star shelter directly expanded many, many times.
These changes are very obvious, and every survivor living in the underground castle of the star shelter can clearly feel it.
It was also from that time that everyone had guesses in their hearts, and vaguely realized that this kind of technology is definitely not something that earth civilization can possess.
Later, Li Chen directly confessed that the star shelter did use the technology of alien civilization.
Instead of causing panic and fear among the survivors, this made them admire and respect Li Chen even more.
Generate stronger dependence and trust on star shelters.
So at this moment, once again going through the process of upgrading the star shelter.
The vast majority of survivors are just happy and excited.
I didn't feel anything abnormal or feel scared.
As for those who have just joined the star refuge, it hasn't been long.
Survivors who don't know and haven't experienced these amazing things at all.
Naturally, someone who understands will explain it for them.
In addition, the current survivors generally have a super receptivity.
So basically, there was not much commotion during the whole upgrade process.
【Ding! The upgrade of the star shelter is complete! 】
[The current level of the star shelter is three stars, and the protection level is upgraded to S, and the following automatic firepower system is unlocked...]
[Host, you can check the specific upgrade changes by yourself! 】
Noah's voice sounded in Li Chen's mind.
Hearing this, Li Chen immediately clicked on the detailed information operation panel of the star shelter.
【Star Shelter System】

The attribute panel in front of him shows the entire three-star star shelter in detail.
Various aspects of attribute information.
Including population capacity, resource capacity, firepower system and protection system and so on.
But what surprised Li Chen even more.
Star shelter after upgrading to 3 stars.
It even comes with a layer of super energy protection barrier!
It seems that my trillions of evolutionary resources are completely worth it!
