Looking at the scene on the computer, Chen Nuo's expression became a little serious.

"Is this an electromagnetic cannon?" Chen Nuo couldn't help but murmur.

He was a little surprised at the power of the electromagnetic cannon.

That kind of terrifying beam that feels shocked even through the screen is simply terrifying!

"This kind of power is probably a little stronger than the power of tank shells!" Chen Nuo's heart sank.

...

At the same time, the light quickly dissipated. Looking closely, the black hole below returned to its former darkness, and the earth-core bird disappeared.

This scene made everyone stunned.

"This... why didn't you use this weapon earlier?" the drone shouted indignantly.

However, at this moment, the fighter jet No. 2, which had fired the electromagnetic gun, fell down as if it had lost its buoyancy.

Fortunately, the fighter No. 1 quickly caught it.

At the same time, Fighter One glared at the drone and said:

"This is not something you can use if you want to. Once you use it, the power depends on all your energy. The attack just now has used all its energy!"

Hearing this, the drone shut up instantly, then flew over, looked at the fighter No. 2, and said:

"Then it's OK?"

"I'm fine... I just don't have enough energy to drive me to move." Fighter 2 said in a weak tone.

"Stop chatting! They are coming again!" Suddenly, the drone looked below and shouted in shock.

Everyone looked at them, and at this moment, countless core birds were flying quickly with their wings.

This scene made everyone's faces sank.

Fighter One didn't think much about it, and flew up quickly with Fighter Two in his arms.

Because they are very fast, they leave the black hole without any danger and come to the ground.

"Huh..." The drone sat directly on the ground, looking tired and paralyzed.

The others were relieved.

"Come back quickly." At this time, Chen Nuo's voice came from the unmanned reconnaissance plane.

"Yes!" They responded and then began to head towards the shelter.

...

"Thank you for your hard work." Chen Nuoyu looked at them earnestly and said.

"This is what we should do!" said Fighter One.

"We are willing to refuse to do the tasks assigned by the master, even if we go up to the mountain of swords or the sea of ​​fire!" The drone slapped his chest and said righteously.

Suddenly, everyone's eyes shone.

"You can run the fastest." The drone said with a lip silence.

"...I... Actually, I'm just following the orders of my master." The unmanned fighter thought for a while and said righteously.

Chen Nuo ignored it, looked at the fighter jet No. 2 and said:

"how's it going?"

"Master, don't worry, my energy will be restored after a while." Fighter 2 replied.

Chen Nuo nodded and said:

"You guys did a good job this time, let's go and have a rest first."

...

After seeing them off, Chen Nuo sat on the sofa, watched the video replay previously recorded by the unmanned reconnaissance plane, and began to observe.

"Although bullets cannot cause powerful damage to them, they are not without any damage..."

According to observations, the evolved nuclear beasts have enhanced their ability to defend against bullets, but they are not really afraid of bullets.

Apart from that, their speed has almost doubled!

Moreover, the damage power has also been increased.

And this is just the evolution of the Earth-core bird.

As for the changes in the Earth-core wolf, Chen Nuo doesn't know yet.

But it is probably like a core bird.

"It seems that it is still a bit difficult to obtain an upgrade point with this." Chen Nuo couldn't help but ponder.

After all, judging from the current situation, if the fighter planes are allowed to go down again, there will be casualties.

However, I just don’t know how powerful the formation can be on them.

Of course, I think so, but the formation is naturally impossible to set under the ground. After all, if the formation wants to activate, it must let itself go underground.

In that case, those core beasts will definitely kill themselves crazy.

This idea obviously doesn't work.

However, setting the formation at the entrance of the black hole is a good choice.

But, not yet now.

Because the third wave of disasters will last for a month of cold winter, and these nuclear beasts will surely hibernate by then.

Therefore, if the formation is set up now, then disasters will come and the formation will definitely be covered with heavy snow.

...

"System, how many upgrades do I have now?" In the end, Chen Nuo did not think of any good method, so he could only ask like this.

"13555 upgrade points!" The system's answer surprised Chen Nuo for a moment.

That's more than 10,000?

It seems that hunting nuclear beasts in this way is not bad either.

It's just that it's easy to lose your subordinates...

So, Chen Nuo had to suppress this idea.

After all, now he doesn't want his Transformers Corps to be damaged.

Now, he has more than 10,000 upgrade points, and the next wave of disasters should not cause harm to the current shelter, so there is no need to upgrade the shelter for the time being.

It's dark metal...

Judging from the situation just now, the defense of the fighter jet is too low, and dark metal is a good thing.

However, compared to dark metal, powerful weapons are what he needs most now.

It's best to be the kind of weapon that can shoot 20,000 meters deep and has a terrifying damage!

Listed as nuclear weapons!

Of course, nuclear weapons are too powerful. If they are launched, they are afraid that the entire black hole will be damaged.

Or, people are scared because of movement and stillness, and thus alarm the snake.

"System, how many upgrades are needed to upgrade the scientific research base again?" Chen Nuo asked quickly.

Now he can only look forward to the weapons he needs after the scientific research base is upgraded.

“6400 points!”

"Click out the newly added manufacturing technology of the scientific research base after the upgrade. "Before the upgrade, Chen Nuo can view the detailed introduction after the upgrade.

So, Chen Nuo asked like this.

As soon as he finished speaking, the light curtain appeared in front of Chen Nuo's eyes:

Energy-gathering cannon: The gun body is 1.5 meters long and has a radius of ten centimeters. It can fire a beam that is not inferior to a nuclear bomb, and it will not cause huge movement after launching!

It takes 100 kilograms of black iron, 50 kilograms of copper, and 50 energy crystals to make it!

Mechanical heavy sword: made of pure metal, the sword body is 1.5 meters long and 50 centimeters wide, sharp and hard!

It takes fifty kilograms of black iron and twenty energy crystals to make it!

Black iron: A substance that surpasses iron. One pound of black iron can be made for every ten pounds of iron!

...

really!

Chen Nuo's eyes lit up and he was surprised.

"Hiss... I can't help but sigh." Chen Nuo couldn't help but sigh.

Among them, the energy-gathering cannon is a weapon that can fire comparable to nuclear weapons, and the noise caused is still small!

In addition, there is also a mechanical heavy sword, which can be used as a weapon for his Transformers Corps.

However, the only thing that hurts Chen Nuo is this material.

One pound of black iron is made of ten kilograms of iron, while one hundred kilograms of black iron is needed for energy gathering cannons, and fifty kilograms of black iron is needed for mechanical heavy swords.

After all, one hundred and fifty kilograms of black iron is equivalent to one thousand five hundred kilograms of iron.
