After a while, Noah's voice sounded in Li Chen's mind.

"It's not just that the defense level has improved."

"Has the storage capacity even increased..."

Li Chen didn't notice this before, but he was quite happy when he heard Noah's words.

The number of humans the shelter can hold.

Increased from 200,000 to 500,000.

Suddenly increased the capacity of 2.5 times.

This means that Li Chen is next.

The defense force of the shelter can be upgraded and expanded!

Develop more weapons.

[Congratulations to the host! Your shelter has been upgraded, the current level is 1 star! 】

[The upper limit of shelter material capacity +300%! 】

[The upper limit of the shelter weapon ammunition capacity +300%! 】

[Refuge energy reserve limit + 300%! 】

[Refuge purification system enhancement +300%! 】

…

【You can now strengthen your one-star shelter! 】

[Noah has designed a variety of optional weapons and equipment for you in advance, as well as various enhanced protection measures. 】

[You can choose the host yourself, you only need to consume the corresponding energy crystal cores, you can exchange them and put them into use directly. 】

【Host You can also design and build enhanced content that meets your expectations according to your own preferences and style. 】

Noah's warm reminder sounded again at this time.

"Commander, there seems to be no movement outside!"

Li Chen was browsing the selection window that popped up in front of him.

At this moment, Xu Ruoxi's voice interrupted him.

He came back to himself curiously.

"Noah, show the situation outside again."

When Noah was upgrading the star shelter just now, all the surveillance screens were interrupted.

At this time, under Li Chen's order, it summoned the holographic projection again.

Everyone immediately saw the situation outside the underground command center.

People found that they couldn't hear the movement outside.

It's not because the attacking zombies have receded.

But because of the movement caused by their attacks.

It has been insulated by the composite ultra-metal that has been thickened to 2.5 meters.

But at this moment, their attacks are only on the barrier of this composite supermetal.

Leave a little scratch.

I can no longer easily break through a layer of protective barriers like before!

Seeing such a situation, everyone in the star refuge was very excited.

"The star shelter has been upgraded, and all the previously damaged barriers have been repaired."

"Now these zombies have all become turtles in the urn."

"And they're separated into separate rooms..."

"Commander, how do we deal with them now?"

Party loyalty noticed these situations and asked immediately.

He is already eager to try and destroy these intruders.

"Let Noah tell you."

"Noah, you are responsible for showing them how convenient the star refuge is after the upgrade."

Li Chen issued an order in his mind.

Previously, the star refuge was invaded by an army of zombies from under the ground.

Everyone can only watch helplessly, they are wreaking havoc.

But there is no way to open them and go out to fight.

The upgraded star shelter fully took these situations into consideration.

At this time, Noah began to explain to each warrior.

[In the upgraded star shelter, there is a circular passage between each room. 】

[They are located at the top of each room, and can monitor the entire room from different angles, or they can also be used to encircle any creatures that invade the shelter. 】

As Noah said, he showed these passages in front of everyone.

Li Chen looked up.

It was discovered that the underground command center they were in at this time really began to change.

I saw it at the junction of the ceiling and the wall of the room.

At this time, a gap about twenty centimeters wide appeared.

Behind the gap is a channel protected by a one-meter-thick composite ultra-metal.

The passage can accommodate soldiers to enter.

Using these passages, you can avoid direct contact with zombies or other creatures.

Then launch a siege operation against them!

"Very good!"

"Now we can finally fight directly! We can't do anything without hiding here!"

Xu Ruoxi and Dang Zhongcheng looked at each other with joy on their faces.

Li Chen nodded nonchalantly.

"Now, go and wipe out all the invading zombies."

After speaking, his eyes returned to the selection interface in front of him.

…

the other side.

In the dark and damp underground abandoned laboratory.

In front of the corpse king, stood a zombie that looked like a skeleton.

Although it looks like a skeleton on the whole.

But on top of its bones, there are dark red muscles attached.

This skeletalized zombie not only became huge in size.

It seems to be nearly five meters high.

And at this moment, the aura emanating from its body is also very powerful.

Obviously, it has surpassed many zombies at the peak of the sixth order.

And on his back, there is even a pair of small, white ossified wings!

This zombie looks very familiar.

It was the one that had been criticized and angered by the corpse king several times before.

It has just completed the evolution from the peak of the sixth order to the early stage of the seventh order.

Named Shura.

"Master Corpse King, all the companions we sent to attack the star refuge were wiped out by those **** humans!"

"And just now we also lost contact with all the companions who invaded from the ground!"

There was a sternness and indignation in Shura's tone.

At this time, his fists were clenched tightly.

"hehe…"

"Did you actually let him carry it?"

"That's what makes it interesting."

After listening to Shura's words, the corpse king didn't show any anger.

Instead, he laughed playfully.

His tone and demeanor were as if he heard that Li Chen's star refuge had survived.

It's something to be happy about.

His reaction made Shura very puzzled.

But Shura didn't dare to ask more.

After evolving to the seventh-order form, his intelligence became higher.

At this time, he was not as reckless as before.

I won't do things that easily offend the corpse king.

"Go down first, Shura."

"The next game will be more fun."

"But it's not your turn yet, go back and wait for me."

The corpse king's tone suddenly turned cold.

Restored the majesty of the king.

Hearing his order, Shura didn't dare to disobey and nodded.

"I am always on standby! Master Corpse King!"

After speaking, he raised his eyes slightly and looked at the corpse king's body.

A look of deep fear quickly flashed in the depths of his eyes.

The evolution speed of Lord Corpse King is too fast!

At this time, it is already, is it about to break through the middle stage of the seventh order...
