Located 27,000 meters underground on the earth, here is a space extending toward the surroundings.

On the ground of the space, there is a black monster wolf!

However, these strange wolves are different from all known wolf species.

They have wolves, earless bodies, big figures, and black hair. However, because the ground is too dark, even the unmanned reconnaissance aircraft with lights cannot clearly capture the true appearance of these unknown animals.

However, looking around, the ground was full of these weird wolves!

This shows how terrifying its number is!

...

Looking at this scene, Chen Nuo was silent.

These…

Is it the beast in the core of the earth?!

What species is this?

I was shocked, but no one could answer his question.

Withdrawing his thoughts, Chen Nuo controlled the drone to fly outside.

Now he had some answers in his mind, so he decided to put the drone into the fighter and hunt these monsters in advance.

After all, these are all upgrades for him!

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

But, because the only weapons that I can use to hunt these monsters are drones...

So, he finally decided to take a risk and give it a try, even if it could damage the drone.

...

January 13, 2045.

The sixth day after the first wave of disaster is also the last day before the riot of the core beasts under the ground.

Tonight, the underground core beast will rush out from the ground and hunt humans!

4:32 points.

Chen Nuo, who was sitting cross-legged on the sofa, left the state of cultivation. The reason why he didn't sleep last night was because he was not only not sleepy after entering the state of cultivation, but also was very energetic after leaving the state of cultivation.

This is an effect that cannot be compared to sleep.

Furthermore, now, he is going to be ready to put into the drone, so he didn't sleep last night.

At this time, Chen Nuo loaded the monsters that the drone reconnaissance aircraft were reconnaissance last night into the drone fighter and released the drone out of the shelter.

Because after the upgrade, the unmanned fighter can recognize the enemy to attack, and Chen Nuo does not need to operate it himself.

This is not only simple, but also increases the strength of unmanned fighters to the limit.

Of course, in addition to deploying drones, he also deployed drones.

After all, he needs to watch what they fight so that he can recover the drone in time when the situation is not good.

...

At four o'clock, it was still dark, not only that, it was a bit cold.

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

Entering the black hole, the four little guys did not stop at all and dived directly.

They were very fast and arrived at a location of 15,000 meters in less than an hour.

Then, they stopped.

As the reconnaissance plane lights shone, strange birds appeared on Chen Nuo's computer on the surrounding walls.

In response, Chen Nuo operated the drone to fly upwards, and as for the three drone fighters, they were ready to fight below.

When the drone arrived at a position one or two hundred meters above, Chen Nuo pressed the button that had already prompted him to attack!

In an instant, four or five small ammunition tubes popped up under the fuselage of the three unmanned fighters.

Immediately afterwards, bullets cut through the night and bombed towards the surrounding walls!

Da da da da da!

Gunshots resounded throughout the black hole!

The bullets were fired at the surrounding walls like a storm!

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

In an instant, countless monster birds flapped their huge wings and came down from the wall. Among them, countless monster birds had blood-red eyes full of anger, and then they opened their sharp mouths and started to sing!

Song!

For a moment, the terrifying voice of the strange bird resounded through the black hole!

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

It was a huge monster bird with huge wings, a head as black as a crow, and a sharp sword with its pointed mouth.

Seeing this, Chen Nuo's pupils couldn't help but shrink slightly.

These…

But a species that humans have never seen before!

"Ding, you killed a monster bird and gained five upgrade points!"

"Ding, you killed a monster bird and gained five upgrade points!"

"Ding, you killed a monster bird and gained five upgrade points!"

...

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

But soon, the projection in the computer in front of him made Chen Nuo stunned.

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

In an instant, in the dark black hole below, the black monster birds that were originally attached to the wall opened their blood-red eyes one after another, then came down from the wall, flapping their huge wings and storming towards the drone!

In response, three pipes that were twice as big as the barrel popped up next to the barrel under the fuselage of the unmanned fighter!

That's the shell tube!

Seeing this, Chen Nuo was a little surprised, and then, he instantly fired three small missile guns slightly larger than bullets from the shell tube!

Strange birds flapped their wings and rushed over, hitting the shells, causing a dazzling explosion in an instant!

boom!

An explosion suddenly appeared!

Thick smoke spread everywhere, and strange birds were injured or killed by the explosion of the shell.

However, the number of strange birds is too large, just like a fountain.

For this reason, several monster birds took the opportunity to break through the defense line and killed them, but the combat ability of the drone was very strong. They easily avoided the attacks of the monster birds and then killed the monster birds.

However, the number of these strange birds was really ridiculous, and they were very fast. Soon after, the three unmanned fighters were suppressed and had to fly upwards.

Looking down, countless strange birds came to fight hard, and the scene was extremely terrifying!

This scene surprised Chen Nuo.

Although the monster birds have very weak defense and can kill them with just a few bullets, their speed is extremely fast and large in number. If they have an attack power, they should not be worse than the lion's attack power!

During the analysis, the strange birds in the computer kept approaching the unmanned fighter jets, which made the unmanned fighter jets and the unmanned reconnaissance aircraft have to retreat upwards.

At the same time, the sound of bombing and bullet launches kept ringing, and of course, the angry chirping of strange birds.

At this time, as the monster birds continue to approach, the drone fighter and the drone reconnaissance aircraft were forced to rise to altitude, and at this time, they had reached a depth of 5,000 meters!

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

However, the group of monster birds in front of you didn’t have any intention of retreating at this time!

This made Chen Nuo stunned.
Chapter completed!
