The words of the President of the United States have not been finished, and he no longer has the strength to speak.

That kind of fear made his body seem to lose strength in an instant.

All the forces that supported his combat power were almost hollowed out.

In the picture, Xuanyuan is invincible in the storm and bombardment, standing proudly.

Countless parts have fallen from the sky, and the super soldiers have already broken into slag!

The explosion just now was indeed successful!

However, Xuanyuan Invincible survived, including the neutron light bomb with great lethality.

"I've disappointed you, and you're probably going to be unable to keep up!"

In the huge room of the Black Palace, no one spoke.

They could only see Xuanyuan Invincible, speaking arrogantly in the direction of the reconnaissance plane.

It turned out that Xuanyuan was invincible, and he always knew that he was being watched!

But now, Xuanyuan is invincible, and no one will be able to stop him.

"He's faster!"

"The speed has reached 12 kilometers per second, and the speed is still increasing!"

He ...... He accelerated again, and the reconnaissance plane couldn't catch up!"

"It's over, it's over, we've lost the trace of Xuanyuan Invincible......"

Monitoring information keeps coming, and the president of the United States, high-level bigwigs, no longer have any arrogance.

"Activate the Seven Interception System, no matter what, you must ensure the safety of the Black Palace!"

Although he didn't know where Xuanyuan was invincible, the president of the United States knew very well that the other party's goal was.

No matter what, Xuanyuan Invincible will definitely appear in the sky over the mainland of the United States.

Now the only thing that can stop Xuanyuan from being invincible and detonating a neutron light bomb is to rely on the local defense system.

This is the last barrier!

Even if the United States itself is all fallen, as long as the country is safe and the Black Palace is still there, there is still a little hope.

Within the territory of the United States, those secret anti-missile systems, anti-aircraft systems, unmanned suicide planes, anti-aircraft equipment, and so on, almost layer by layer, layer by layer, have formed an unprecedentedly powerful network of interception systems.

The entire system, covering the territory of the mainland, with a radius of several million kilometers, is densely packed with large-scale equipment of the armed forces of the armed forces, and all of them are unveiled at one time.

For example, all kinds of fighters will assist unmanned suicide planes in the battle and strive to intercept unknown dangers.

"Estimated speed, Xuanyuan Invincible will arrive at the mainland in one minute!"

"50 seconds!"

"30 seconds!"

"10 seconds!"

All the big people in the Black Palace, their fear and nervousness are beyond words, everyone is on the big screen, countless pictures, no one knows where Xuanyuan Invincible will appear.

3 seconds!

1 second!

The countdown was really accurate, and after Xuanyuan Invincible disappeared for more than 3,000 kilometers, he really appeared on the mainland of the United States.

The picture was quickly enlarged, and Xuanyuan Invincible galloped towards him at a speed that was incomprehensible to humans, surpassing all obstacles.

Countless anti-aircraft missiles, continuously launched, the only target, only Xuanyuan is invincible.

Like hundreds of millions of crows flying, the seemingly chaotic massive number of anti-aircraft missiles accurately impact from various angles, using Xuanyuan as an explosive point.

Xuanyuan Invincible smiled faintly, and his speed increased even more amazingly.

An unusually terrifying sight appeared in the sky!

A human being, stepping on a neutron light bomb, has about 10,000 anti-aircraft missiles launched by an interceptor system behind him.

The dense masses of missiles gradually moved forward, forming a long straight line.

The long line is becoming more and more slender and more conspicuous, and even the naked eye can see the clear lines on the ground, thousands of meters in the sky.

The big names in the Black Palace are already crying.

They forget a very serious fact!

The existing anti-aircraft missiles in the United States have limited speed and cannot be pursued at all, surpassing the speed of human understanding of Xuanyuan invincibility, let alone interception.

The fuel of missiles is short and explosive, and the speed is at the first time, reaching the maximum, and then decaying.

If you don't catch up in the first place, you can't catch up again!

What's more, fuel is limited!

Countless missiles fell from the sky during the pursuit!

This is a catastrophe!

"Quick, quickly stop the anti-air interceptor missile, give up and enter the next link, drone interception, hurry!"

The instructions in the Black Palace are constantly changing, and no one has thought of what method should be used to intercept Xuanyuan Invincible.

Xuanyuan is invincible, indomitable, like entering a no-man's land.

The terrifying hordes of unmanned suicide planes began a frantic pursuit and interception.

The second layer of defense has been fully opened.

The United States has entered a three-level defense state, and the local security alert has been directly raised to an orange alert!

In addition to a large number of unmanned suicide aircraft, there are also photonic weapons, and even the most advanced nano-level fighters in the United States have been dispatched as many as dozens of them.

These strategic-level fighters have extremely powerful anti-reconnaissance and stealth capabilities, and can quietly gain huge strategic value on the front-line battlefield.

What's even more terrifying is the built-in destruction system of these nano fighters, which can smash everything within a radius of one kilometer.

The United States has taken out all the money that can be used.

And at this moment, Xuanyuan is invincible, and has entered the sky above the capital of the United States.

In just three minutes, Xuanyuan Invincible can enter the Black Palace.

At this time, Xuanyuan Invincible suddenly changed his strategy and carried out threatening bombing of unmanned suicide planes and various long-range interception fighters that were constantly chasing behind him.

"A swarm of pesky flies!"

Xuanyuan Invincible raised his hand, his ten fingers were like claws, shocking the sky.

In the sky, there was a dull banging sound like thunder.

Boom!

The loud noise produces an astonishing sound wave that quickly radiates in all directions.

In an instant, within a radius of 100 meters, all the entangled fighters and all the high-tech combat equipment like flies turned into smoke and dust within a second.

The explosions continued one after another, and Xuanyuan was invincible for ten miles in one step, and the speed was outrageous.

The sky was filled with fireworks and countless wreckage.

"Quick, all defense systems, intercept at the same time, start quickly, quick!"

In the black palace of the United States, they have exhausted their donkey skills, and all their means have been almost exhausted.

However, there was simply nothing that could stop Xuanyuan from being invincible and domineering.

Dead horses are treated as live horse doctors, and they must fight with all their might, which is the only belief of the president of the United States.

One minute!

Xuanyuan Invincible blew up more than 100 interceptor fighters, and he is still soaring!

Two minutes!

Xuanyuan is invincible and continuously detonated, with more than a thousand interception devices, only one step away from the Black Palace!

"Retreat, enter the Doomsday Plan, transfer all scientists, transfer all technicians......"

Under heavy protection, the president of the United States carried out the final action!

Desertion!

This is the saddest, but the only way!

Xuanyuan Invincible is already close at hand, less than a hundred kilometers.

In the last time, except for escaping and preserving the living force, everything else is nonsense!

The Black Palace has fallen into unprecedented chaos, and the president of the United States is like an ant on a hot pot, except for the guidance of the security personnel, he has no freedom to call the shots.

"Go underground, quick, all transfer, go underground!"

The most powerful defense system in the United States has always been under the ground of the Black Palace.

Fight against nuclear bombs, world-destroying catastrophes, and can be perfectly defended.

Here there is a stockpile of supplies and food for a thousand people for up to three years.

No matter how the sky falls, this is where the president and scientists can all survive.

Boom!

Thundered!

The last barrier, the last defense, the defense that can resist the doomsday level catastrophe, was completely disintegrated in a second.

Xuanyuan Invincible kicked through all obstacles, holding aloft a neutron light bomb with the ability to destroy the world.

"Nukes for you!"

Airplanes!

As soon as he raised his hand, Xuanyuan Invincible threw the neutron light bomb at the president of the United States.

The audience fell into an extremely terrifying panic!
