Global Catastrophe: I Am Cultivating Immortals in the Refuge

Located 27,000 meters below the earth, here is a space that extends around.

On the ground of the space, there is a mass of strange wolves in darkness!

However, these strange wolves are different from all wolves known to people.

They have mouths like wolves, no ears, bodies as big as lions, and black hair all over their bodies. However, because the ground is too dark, even unmanned surveillance drones with lights on cannot clearly capture the true appearance of these unknown animals. down.

However, looking around, the surrounding ground is full of such strange wolves!

This shows how terrifying its number is!

...

Seeing this scene, Chen Nuo fell silent.

These…

Is it the beast at the core of the underground? !

What kind of species is this?

His heart was shocked, but no one could answer his question.

Putting away his thoughts, Chen Nuo controlled the unmanned reconnaissance plane and flew outside.

Now he has some answers in his heart, so he decided to put in the unmanned fighter jets to hunt and kill these monsters in advance.

After all, these are all upgrade points for him!

However, the only thing that worries Chen Nuo is the attack power of the current unmanned fighter jets...

However, because the only weapons I can use to hunt these monsters are unmanned fighter jets...

Therefore, he finally decided to take a risk, even if it might damage the UCAV.

...

January 13th, 2045.

It was the sixth day after the first wave of catastrophe, and it was also the penultimate day before the ferocious riot at the core of the underground.

Tonight, the underground core ferocious beasts will rush out from the ground to hunt and kill humans!

4:32 minutes.

Sitting cross-legged on the sofa, Chen Nuo withdrew from the cultivation state. The reason why he didn't sleep last night was because not only would he not feel sleepy after entering the cultivation state, but he was still very energetic after exiting the cultivation state.

This is an effect that cannot be compared with sleep.

Furthermore, now, he was going to prepare to invest in the unmanned combat aircraft, so he didn't sleep last night.

At this time, Chen Nuo loaded the appearance of the monsters detected by the unmanned reconnaissance plane last night into the unmanned fighter jet, and then released the drone fighter plane out of the shelter.

Because after the upgrade, the unmanned fighter can identify the enemy to attack, and there is no need for Chen Nuo to operate it himself.

This is not only simple, but also can enhance the strength of the unmanned fighter to the limit.

Of course, in addition to launching unmanned fighter jets, he also launched unmanned reconnaissance aircraft.

After all, he needs to watch what they are fighting, so that he can recover the UCAV in time if the situation is not good.

...

At four o'clock, the sky was still dark, not only that, but also a little cold.

At this time, three unmanned fighter jets and one unmanned reconnaissance plane quickly entered the black hole, making it difficult for patrolling soldiers to detect.

Entering the black hole, the four little guys dived directly without stopping.

Their speed was very fast, and they reached the position of 15,000 meters in less than an hour.

Then, they stopped.

Under the light of the reconnaissance plane, figures of strange birds appeared on Chen Nuo's computer on the surrounding walls.

In response to this, Chen Nuo controlled the unmanned reconnaissance plane to fly upwards, while the three unmanned fighter jets were below, ready to fight.

When the unmanned reconnaissance plane came to a position of one or two hundred meters above, Chen Nuo pressed the button that had already reminded him whether to attack!

In an instant, four or five small bomb tubes popped out from under the fuselage of the three unmanned fighter jets.

Immediately afterwards, bullets pierced the night and bombarded the surrounding walls!

Da da da!

Gunshots resounded throughout the black hole!

Bullets shot towards the surrounding walls like a storm!

To be exact, it was shooting at the strange bird on the wall!

for a moment,

Countless strange birds flapped their huge wings and came down from the wall. Among them, the blood-red eyes of countless strange birds were full of anger, and then they opened their sharp mouths and screamed!

Moan!

All of a sudden, the terrifying sound of the strange bird resounded through the black hole!

And at that moment, Chen Nuo also saw clearly the appearance of these strange birds!

It was a huge strange bird with a pair of huge wings, a black head like a crow, and a sharp beak like a sharp sword.

Seeing this, Chen Nuo's pupils shrank slightly.

These…

But a species that humans have never seen before!

"Ding, you killed a strange bird and got five upgrade points!"

"Ding, you killed a strange bird and got five upgrade points!"

"Ding, you killed a strange bird and got five upgrade points!"

...

Just when he was stunned, this kind of notification sound appeared in his ear for the first time.

But soon, Chen Nuo was taken aback by the projection on the computer in front of him.

Because, these strange birds were all awakened by the sound of fighting!

In an instant, in the pitch-black hole below, the black strange birds that had been attached to the wall opened their blood-red eyes one after another, and then came down from the wall, fluttering their huge wings and killing the unmanned fighter jets one after another!

In this regard, three tubes twice the size of the barrel popped up next to the barrel under the fuselage of the UAV!

That's a cannonball tube!

Seeing this, Chen Nuo was a little surprised, and then, three small missiles that were slightly larger than the bullets were fired from the shell tube in an instant!

A strange bird rushes forward with flapping wings, hits the cannonball, causing a dazzling explosion in an instant!

boom!

Then there was an explosion!

Thick smoke was everywhere, and each strange bird was injured or died by the explosion of the shell.

However, the number of strange birds is really too much, like a fountain pouring in continuously.

For this reason, several strange birds took the opportunity to break through the defense line and killed them, but the combat ability of the unmanned fighter jet was very strong, and it easily avoided the attack of the strange birds, and then killed the strange birds.

However, the number of these strange birds is ridiculously large, and their speed is very fast. It didn't take long for the three unmanned fighter jets to be suppressed and had to fly upwards.

Looking down, countless strange birds are struggling to kill, the scene is extremely frightening!

This scene made Chen Nuo astonished.

Although the defensive power of the strange birds is very weak, and they can be killed with only a few bullets, but their speed is extremely fast, their numbers are large, and their attack power... should not be inferior to that of lions!

During the analysis, the strange bird in the computer kept approaching the drone fighter, causing the drone fighter and the drone reconnaissance plane to retreat upwards.

At the same time, the sound of bombing and bullet firing continued to sound, and of course, there was also the angry chirping of strange birds.

At this time, as the strange bird continued to approach, the unmanned fighter plane and unmanned reconnaissance plane were forced to rise in altitude. At this time, they had already reached a depth of five kilometers!

In other words, there are still five kilometers to fly out of the black hole!

However, the group of strange birds in front of them didn't have any intention of retreating at this moment!

This made Chen Nuo stunned.

"This is..." His face was dull, as if he had thought of something, he hastily ordered the unmanned fighter jets and reconnaissance planes to retreat!
