January 26, 2045.

On the sixth day after the second wave of disasters, the sky of the whole world was gray.

It was daytime, but it was very dark, it was that weird blackness.

The wind blows very lightly, but it has a biting cold.

Not only that, there are snowflakes dancing in the sky.

It’s snowing!

...

At the same time, Chen Nuo's refuge.

Because the temperature suddenly dropped, Chen Nuo woke up by the cold and couldn't fall asleep.

"Tomorrow is the third wave of disasters. It seems that the temperature is about to gradually drop." Chen Nuo wore a coat and pondered in his heart.

It is estimated that the temperature will reach minus one hundred degrees below zero at midnight, and the temperature will start to drop rapidly from this morning to evening.

Thinking of this, Chen Nuo turned on the heater and turned the temperature to twenty degrees.

Then, he came to the third floor scientific research base and planned to check the production progress.

The speed of scientific research did not disappoint Chen Nuo. When Chen Nuo arrived, there was already an energy-collecting cannon on the finished table with a color of white, up to 1.5 meters long, and the width of the barrel mouth was one or two times wider than Chen Nuo's waist!

Behind the energy-gathering gun is a groove, and the barrel has a button.

Seeing this, Chen Nuo's eyes lit up and he walked over quickly.

"Scientific research, how do you use this?" Chen Nuo asked after observing.

"Put the energy crystal first, then press the button to fire the energy-concentrating cannon. The power of the energy-concentrating cannon depends on the number of energy crystals!"

Upon hearing this, Chen Nuo frowned.

I've been hasty and forgot to ask about how to use it before.

I didn't expect it to be used with energy crystals.

You know, energy crystals are also very expensive...

"So, how many energy crystals need to be installed to launch its maximum power?" Chen Nuo couldn't help asking.

"Ten!"

Upon hearing this, Chen Nuo nodded, barely accepting such a price, and then thought of something and asked:

"Can the materials make four mechanical heavy swords now?"

"Yes!" With the scientific research answer, Chen Nuo directly ordered:

"Okay, make me four mechanical heavy swords!"

Since the materials are enough, then make some mechanical heavy swords to increase combat effectiveness to the Black Skins.

As the robot arm operates, Chen Nuo takes an automatic lift to the parking garage on the first floor.

At this time, in the parking garage on the first floor, they were fighting against each other.

But when Chen Nuo came here, they ordered to stop and then shouted in unison:

"Owner!"

"Well, you guys continue, Fighter 1 and Fighter 2, come with me." Chen Nuo nodded and said.

"By the way, take this thing over together." Chen Nuo said as he turned around and walked outside.

...

In the living room, Fighter One carefully placed the energy-gathering cannon on the ground.

Chen Nuo looked at them and said:

"This is a weapon I asked scientific research to make. It is very powerful, and the reason for making it is to let you help me deal with the monsters under the ground."

Upon hearing this, the two of them also understood.

At this moment, Chen Nuo took out ten energy crystals from his pocket and placed them on the table.

Then, Chen Nuo came to the energy gathering cannon, picked up an energy crystal and said:

"The way to use this weapon is very simple. You just need to put this in here and press this button on the monsters."

After saying that, Chen Nuo stood up and asked:

"Do you understand?"

"I understand!" They nodded in a vague way.

Nodded, Chen Nuo said:

"Okay, you will use this weapon to enter the black hole again later, and then fire this weapon at those monsters once!"

As he said that, he raised the energy crystal in his hand and said:

"At that time, you only need to put five such stones in it. Remember, don't put too much. Also, you must leave the black hole immediately after launch!"

"Okay!" They nodded one after another.

"Well, now, you can try to see how this weapon is used." Chen Nuo nodded and said.

Hearing this, they squatted down and tried to use it.

...

Because Chen Nuo did not let the drone follow him this time, Chen Nuo did not know the specific situation.

After all, the power of the energy-gathering cannon is very powerful and may affect the unmanned reconnaissance aircraft, so Chen Nuo did not let the unmanned reconnaissance aircraft follow him.

This can be seen from the point where Chen Nuo ordered them to launch and leave.

However, although the drone was not allowed to follow, Chen Nuo turned on the camera that was installed on the black hole building before.

However, this does not show the specific situation inside.

However, you can see the power of the energy gathering cannon.

This is very good.

...

At this time, in the camera's picture, fighter jets 1 and 2 were standing outside the black hole with energy-gathering cannons.

Obviously, they are preparing.

Soon, they entered the black hole.

Seeing this scene, Chen Nuo couldn't help but feel worried about them.

...

At the same time, in the black hole, Fighter 2 was fighting with energy-gathering cannons on its shoulders, while Fighter 1 was ready for combat.

"I will fire bullets later. When these guys come, we will rise. If you rise about 500 meters, you will fire the energy-gathering cannon, and then we will leave quickly!" said Fighter One.

This was what Chen Nuo ordered them, and the reason why they caused hatred among these nuclear beasts and then rose by hundreds of meters before firing the energy-gathering cannon was to allow these monsters to gather more.

In this way, Chen Nuo can make a profit in an instant after one shot.

However, the operation depends on two of them.

"Okay." Fighter 2 nodded.

One hour later, they reached a depth of about 15,000 meters.

Around the surroundings, the figures of the earth-core birds appeared, and the two stopped, and then rose by more than ten meters.

The reason for this is to facilitate the convenience of the earth-core birds not being entangled by the earth-core birds after they will attract the attention of the earth-core birds.

At this time, the bullet tube that fired bullets on the arms of the fighter plane No. 1 bounced out of it.

Immediately afterwards, dozens of bullets were fired instantly!

Da da da da da!

The sound of bullets rang in the black hole.

Ting!

The next moment, the chirping of the birds in the core of the ground sounded.

"Retreat!" Fighter One shouted, and then the two began to rise.

They are very fast, and it is hard to catch up with the birds that are so fast that they are hard to catch up with.

At the same time, the number of ground-core birds is also increasing rapidly.

Obviously, the movement and stillness all woke up the core birds!

Seeing this, the two looked at each other, and then the fighter plane No. 2 suddenly stopped and aimed the energy-gathering cannon below.

Almost without much thought, it pressed the button directly!

"Go to die!" As the roar sounded, a strong light suddenly appeared!

The terrifying light instantly illuminated the entire black hole!

A dazzling beam of light burst out, and rushed towards the core birds ahead as if they could swallow any substance!
Chapter completed!
