I shocked the whole world!

The appearance of the Collapse Crystal shocked Ye Nan.

That's what he needs most right now.

The technology that relies on ordinary construction to unlock can no longer meet Ye Nan's needs.

Now.

Yenan's fortress is not so much a fortress as a small base.

It was far from the heavenly steel fortress that Ye Nan imagined.

It's not just scale, it's technology.

And to unlock some of the more awesome technologies, the only thing you need to use is the Honkai Crystal!

However, this time the collapse crack was solved by Ye Nan from the appearance to the closure of Ye Nan.

All the mutants were killed, but none were found.

Ye Nan, who was originally a little confused, suddenly saw the appearance of the Collapse Crystal at this time, and of course he was excited.

In the isolation room, several staff members are busy.

Seeing that the person suddenly broke out, several staff members were frightened and stupid, and they wanted to run out like crazy.

But right now.

They haven't opened the door yet.

Duh!

The door is automatically locked!

Several staff members were trapped inside, crying and shouting in the direction of the glass.

"What do you mean? Don't let them out? "

Ye Nan's face instantly became gloomy.

Such a scene is often seen in some zombie films that Ye Nan has seen in his previous life.

To stop the spread of viruses and infections.

At the moment of the zombie outbreak, the villain will completely seal the isolation room.

But this scene happened in front of him, and Ye Nan couldn't bear it.

Jiang Zhenbei also frowned, pulled the staff beside him, and scolded angrily.

"What the hell is going on!"

"I... It's not that I did it, this is the program design of the isolation room, if there is an emergency, the program will judge itself and then start the emergency plan to deal with it, this..."

"The so-called emergency plan is to let the staff die? What a shit program! "

Jiang Zhenbei was also angry at this time.

"Don't worry so much, open this door!"

Ye Nan urged and shouted.

Jiang Zhenbei took out a pistol from his waist and shot it at the doorknob.

Peng!

Next second.

Sparks splattered, but the doorknob was intact!

"Useless, useless, this doorknob is made of special materials, even the door and the surrounding walls are high-strength bulletproof materials..."

Jiang Zhenbei heard the words even better.

Through the glass door, it was already possible to see that one of the staff members inside was thrown out by the mad mutant and fell heavily against the wall.

One was scratched on the arm, and the remaining two were still frantically running away and dodging.

Suddenly.

Ye Nan stretched out a hand.

The watch on the wrist flashes with electricity.

Click!

The special material of the doorknob was melted in an instant.

This is not unlocked by the technology tree, but a small thing that Ye Nan has transformed himself according to what the technology tree unlocks.

Because he couldn't use it all the time, he almost forgot.

Now I suddenly remembered.

Jiang Zhenbei looked at Ye Nan in amazement, especially the children's watch on Ye Nan's wrist.

His pistol can't even hit the doorknob, don't a children's watch to melt instantly!

This Ye Nan is simply full of treasures!

But at this time, there were not so many Gu, and Jiang Zhenbei bore the brunt of entering the isolation room.

Ye Nan was about to follow, but was stopped by Jiang Zhenbei.

"Ye Nan, you can't go in, if something dangerous happens to you, the loss will be too serious.

"The lives of those staff members are at stake, they are in danger and the losses are serious."

Ye Nan said lightly, and his body flexibly bypassed Jiang Zhenbei and entered the room.

At this time.

The last two survivors had been cornered.

When you see that you are about to be pounced on by mutants.

Several people appeared on the spot.

As if sensing the movement behind him, the mutant suddenly turned his head to look at Ye Nan and the others.

Then he pounced with his mouth open and screaming.

The bone spurs on both hands stabbed at the head of Jiang Zhenbei, who bore the brunt of the attack.

Jiang Zhenbei reacted quickly and was not in trouble.

The pistol thumped and came with a few point shots.

But the effect is poor.

Although this mutant has not fully grown, in this state, he can no longer feel pain.

The bullet pierced the flesh and blood, but could not hurt the bones.

He only paused slightly, and then erupted again.

This was something Jiang Zhenbei did not expect, seeing that the bone spurs were about to pierce his head, his face changed greatly.

Good at the last crucial moment.

Peng!

Ye Nan raised his hand.

The mutant's head burst instantly.

Sighing, Ye Nan felt a little pity, because of the relationship between the Collapse Crystal, he also planned to study this mutant well.

As a result, he now has to die because he wants to save people.

Bite!

[Congratulations to the host, successfully obtained the Honkai Crystal: 1]

Well?

This is what you get?

Ye Nan glared in surprise.

I originally thought that this Honkai Crystal was some kind of physical object, crystal or something, but I killed this mutant and obtained it directly?

This feels a bit like playing a silent game where you get some kind of currency by killing monsters.

Jiang Zhenbei watched the mutant in front of him who had been hit on the head and slowly fell.

The chest heaved violently.

After being the Minister of Defense for so long, this is the first time I have encountered such an exciting thing.

In such a position, he knew that he could face the consequences of being assassinated by a killer and pierced by a bullet in the head.

But he never thought that his head would be pierced by bone spurs.

Turning his head and looking, Jiang Zhenbei hurriedly beckoned his subordinates to subdue a few staff members.

The one thrown on the wall, the injury is not serious, it is just that the five internal organs have shaken a little.

The two in the corner of the wall stretched out their hands flexibly and quickly, Ye Nan and they came in at the right time, and there was nothing wrong.

The only notable thing is the staff member who scratched his arm.

According to the zombie movie, this can be properly infected.

Thereupon.

The man was quickly isolated, treated, and observed.

Ye Nan did not stop it.

Although the source of infection has not been found, what if?

It's better to be careful.

"Ye Nan, are you all right?" Ye Xiangling was stunned to see this scene, and was also shocked when she saw the mutant's head being exploded.

Ye Nan shook his head.

Walked to the mutant and crouched, checked it, and found nothing special.

"What the hell is going on here? The mutants have all been killed, but why did our countrymen suddenly mutate like this? "

Jiang Zhenbei looked at the strange appearance of the mutant in front of him, and muttered with a slight frown.

Ye Nan's eyes narrowed slightly.

Looking at the sky outside the window, which had already returned to normal, he muttered, "Unless, when the Collapse Crack opens, something else mixes in." "
