In the South China Sea, the steel armor flew at full power, almost clinging to the sea surface and galloping away, at this time, Ye Fan's speed had reached three times the speed of sound, which was the speed limit that the steel armor could reach.

This is also something that can't be helped, why the space-based weapon "Xuanyuan Sword" can fly so fast, it is entirely because it is very lightweight, and its design is completely aerodynamic, otherwise it would not be able to fly so fast with just three ion engines.

As the saying goes, as long as the thrust is sufficient, the bricks can fly into the sky, and the thrust of the four ion engines is no joke, and the thrust of each engine is stronger than the thrust of the huge engine on the Boeing 747.

If it weren't for the fact that Amejian's side had not yet made a breakthrough in the related technology of batteries, the ion engine would have to be installed on the power station to operate, otherwise this thing could at least be installed on the fighter jet by them.

And Ye Fan's steel armor has been transformed, and it can be aerodynamic to the greatest extent possible, so that it can minimize air friction, so that the speed of flight can be greatly improved.

However, even after many transformations and optimizations, being able to reach this speed is already the limit of the Iron Warframe, and it is impossible to be faster.

About fifteen minutes later, Ye Fan had already flown directly out of the South China Sea, and according to the plan, Ye Fan would fly straight in this set of steel battle armors, climbing quickly like a rocket.

According to Ye Fan's plan, the flight speed of his steel armor is three times the speed of sound, while the flight speed of the second generation of steel armor is twice the speed of sound.

In order to arrive in Chicago as soon as possible to save people, Ye Fan's steel armor will be the first to fly, and after entering the laboratory, the second generation of steel armor will wait on the ground.

Because there is no network at all below, even the satellite signal cannot be entered at all, if there is a network signal, Ye Fan does not have to go to Chicago in person.

"I still have to wait until my strength is stronger and I can get this thing out of quantum communication, otherwise my steel legion and the battle of space-based weapons will be very restricted." Ye Fan was also secretly thinking in his heart at this time.

His steel battle armor was like a rocket, suddenly rising in a straight line, and after about ten seconds, he flew directly over the clouds, and Ye Fan could even feel the thrill of directly breaking through the clouds.

Is this what speed feels like?

Ye Fan was also overjoyed in his heart.

It's a much cooler feeling than driving a sports car on the ground, because there are so many obstacles on the ground and there are a lot of factors to consider.

But in the sky, it was completely different, Ye Fan felt like a bird, flying freely and carefree in the air.

After climbing straight to an altitude of nearly 50,000 meters, Ye Fan directly adjusted his flight attitude according to the navigation route of the holographic projection, and moved at full speed in the direction of Chicago.

After flying at full speed for a while, Ye Fan felt that the sky was getting darker and darker, and he could even see that it was dark in front of him, and after adjusting the camera behind him, he found that the sun was still shining behind him.

This means that Ye Fan has come to the so-called "morning and dusk line", and he is getting closer and closer to Chicago.

Because the earth is a sphere, the sun cannot accurately shine on every corner of the earth, only half of it, so the earth will be half day and half night.

According to the time difference, it is still night in Chicago.

And Ye Fan came to the morning and dusk line, which means that he is not far from Chicago, and he can reach it directly as long as he flies at a fixed speed for a period of time.

"Lan Lan, wait for me, I'm coming."

........

Chicago, Greenland Park, Underground Laboratory.

"Hmph, Dr. Kingsley, is that your security? If it hadn't been intercepted by the firewall of my supercomputing base within three seconds, her distress message would have been sent directly to the Huaxia Military Department! You need to know what that means! ”

At this time, in the underground laboratory, Mr. Tang was obviously angry, he grabbed Dr. Kingsley's collar, roared at him loudly, and even sprayed all over his face.

"Hehe, Mr. Tang, this doesn't seem to be my mistake, right? You must know that she sends a distress message through the port of the firewall of your supercomputing base, if it is not for the paralysis of your supercomputing base, how can she use this method to send a distress message? ”

At this time, Dr. Kingsley also spread his hand away, straightened his collar, and looked at Mr. Tang with a sarcastic face.

"I don't care so much about you, in short, you have to understand that her identity is not simple...," Mr. Tang was still chattering in Dr. Kingsley's ear.

"Hmph, Mr. Tang, I don't want to hear so much nonsense from you anymore, even if her identity is not simple, it is not in our hands, even if her father used to be a general, it was only once,

Now that the rank of general has been canceled, he is now just a general, I don't believe that with his identity, he can still really do something to us, hehe, Mr. Tang, those yellow-skinned monkeys will only verbally condemn,

I studied this knowledge for a day, and no one knows them better than me, and besides, if we really want to fight, we have an absolute advantage in military strength.

They can only end up in the same way, which is what they call 'barefoot people are not afraid to wear shoes', but now everyone wears shoes, ours is iron shoes, and theirs is just tattered straw sandals, so there is nothing to worry about. ”

Dr. Kingsley preached to Mr. Tang as if he was pointing the country, and continued to speak, regardless of Mr. Tang's idiot gaze, and continued to speak.

"I think, Mr. Tang, you still have to secretly clean up those people who sneaked into Chicago from Guoan, so that they won't be exposed, rest assured, as long as it takes a year, your consortium will return to the peak of the year."

"Fack, the current scientists are all idiots, although the rank of general has been cancelled, but the influence of the people is still there, not to mention that her grandfather is still one of the marshals of the year, how broad the network is, if we really want to do it, we will definitely not have good fruit to eat,

It's really to the point where you end up together, you mad scientist has completed your experiments, but you die without regrets, I don't want to give up my money and women! Mr. Tang was scolding Dr. Kingsley frantically in his heart at this time.

For a moment, a thought crossed his mind.

This guy can't stay.
