The space-based weapon "Xuanyuan Sword" flew all the way across the sea, and even some radars could not capture its information through special bands.

Because the Earth is spherical and electromagnetic waves propagate in a straight line, it is difficult to detect electromagnetic waves emitted by radar at a height below the tangent when they are tangent to the point where the Earth exhibits an arc.

However, even so, Ye Fan did not dare to be too blatant in the territorial waters, after all, there was a radar that specialized in detecting low altitude in terms of low altitude.

Moreover, the radar is not a few in the deployment of practical applications, but many parts, and the distance between them is different, and there is cross-coverage in the detection distance, thus forming a radar network.

Before it is completely out of the radar network, it is necessary to keep a low profile.

At this time, the flight speed of the "Xuanyuan Sword" had begun to slow down after rushing out of the offshore water.

After all, space-based weapons fly at several times the speed of sound, and the heat generated by air friction is naturally only high, not low, although a lot of heat insulation measures have been taken on non-Newtonian fluid liquid metals, but the body still can't stand flying at full speed for a long time.

After all, non-Newtonian fluid liquid metals are afraid of high temperatures, and the high temperatures generated by air friction are the best killers of this kind of steel.

"Okay, keep flying at this speed, and we can fly out of the South China Sea in fifteen minutes, and no one will be able to control us at that time." Ye Fan also breathed a sigh of relief and spoke.

casually found an office chair and sat down, turning off the monitoring screen of "Xuanyuan Sword".

After leaving the territorial waters, entering the middle of the high seas, the "Xuanyuan Sword" will rise straight like a rocket, and finally levitate in the atmosphere, and carry out a 24-hour non-stop floating cruise in the high air.

At that time, if there is any unexpected situation, the "Xuanyuan Sword" can reach any place in the world within two hours and carry out precise strikes against any target.

....

"Now that the basic weapons are ready today, let's just build a few more." At this time, Ye Fan was also secretly thinking in his heart.

Although space-based weapons are easy to use and can strike targets in real time, they have a fatal drawback, that is, they are very dependent on the network.

For example, the communication between Ye Fan and "Xuanyuan Sword" basically relies on the satellite network, but once there is a place that cannot be covered by the satellite network, "Xuanyuan Sword" will lose its effect.

Although it will not be like in some science fiction movies, some unmanned weapons will automatically fall after losing communication, although the "Xuanyuan Sword" will automatically return to the home, but no matter what, it still can't go anywhere as you want and freely.

For example, in the sea, because the sea water will weaken the electromagnetic waves as much as possible, diving operations cannot be realized for the time being.

There are also some inaccessible places, such as the Amazon jungle, the Sahara Desert in Africa, etc., where satellite signals are not accessible at all.

"Wait, according to the deduction of origin, in 10,000 years before history, the prehistoric civilization that disappeared overnight, the Mayan civilization, was in the Amazon jungle.

And in the depths of the Atlantic Ocean, there should still exist in the so-called Atlantis continent, but after the 'home' was pushed away, the monstrous flood caused by it directly submerged Atlantis.

If you follow this logic, you should be able to infer from the side what happened 10,000 years ago, hey, the matter of the rocket launch center will have to wait until the end of the science and technology conference. At this time, Ye Fan was also secretly thinking in his heart.

"Master, our 'Xuanyuan Sword' is being targeted." At this time, the voice of the origin suddenly sounded in Ye Fan's glasses.

"What's going on?" Ye Fan also frowned, and then let the origin connect to the communication to the origin.

At this time, after 20 minutes of ultra-low-altitude flight, the "Xuanyuan Sword" continued to fly at ultra-low altitude along the sea surface, and at this time it had already flown away from the South China Sea, began to circle around to avoid radar detection in the territorial waters, and flew towards the South Pacific.

Due to the increase in heat caused by air friction due to long-term high-speed flight, there is a possibility that the liquid metal of the non-Newtonian fluid in the shell may melt.

Therefore, Ye Fan reduced the speed of the origin a lot, and the speed was even slower than that of a propeller plane.

At this time, the holographic display on the glasses showed that there were three F22 fighters, hovering at an altitude of several kilometers, they were three patrol planes cruising in the nearby aircraft carrier fleet.

F22 "Goshawk" pilot: "Oh, what is this?!" ”

F22 fighter "Asuka" pilot: "I've never seen this thing, I don't think this thing is aerodynamic at all!" ”

F22 "Freedom" pilot: "I tried to lock it, but I locked it twice and failed!" ”

"Report it to the fleet command immediately, this thing is so weird, it doesn't even have any flight trails, it doesn't seem to be a fuel engine at all!"

"With such a slow flight speed, won't it stall?!"

At this time, the three F22 fighters were constantly hovering in the air, trying to lock on to the target, but Ye Fan's "Xuanyuan Sword" had already adopted a low-speed stepless orbit change at this time, and the route was extremely unfixed, causing the fighters hovering at high altitude to be a little surprised.

You must know that some fixed-wing fighters must fly smoothly at extremely high speeds, for example, some fixed-wing fighters must maintain a smooth flight speed at least 200km/h, if it is too low, it will directly stall and fall.

After all, if a large iron block weighing several tons stalls, it will be rescued by pulling the nose of the plane to start the engine, or the wing will be broken, the spiral will fall, and the plane will be destroyed and killed.

Therefore, the flight speed of the general fixed-wing fighter has always been only high, not low, unless it is some low-altitude fighters, it will maintain slow and stable flight, in order to have more time to aim and pursue, such as A10 fighters.

"Oh! I've finally succeeded in locking it down, and I'll send this information back to the headquarters immediately! At this point, the pilot of the "Freedom" finally locked on to the target after three attempts to lock on.

"There's an order from the command to shoot it down and bring it back for study." It was at this time that the pilot of the "Goshawk" spoke.

However, in the next second, something surprising to him happened in front of his eyes.

I saw that the "Xuanyuan Sword" directly took off into the air, and suddenly rose at a vertical angle of rocket launch, and the speed was very terrifying, much faster than that of air-to-air missiles.

"These flies are so annoying, Origin, close the door and beat the dog." Ye Fan also opened his mouth at this time and commanded the origin.

"Confirm the order, the GPS navigation system in the relevant area is being turned off, and the opponent's navigation and combat map is being forcibly intervened through the terminal access point."

"The intrusion was successful."

At the same time, all the GPS maps in this area were taken over by the origin, and the regiment was forcibly replaced.

"Dora dreams?" At this time, inside a nuclear-powered aircraft carrier two hundred kilometers away, the supreme commander looked at the pattern displayed on the big screen, was stunned for a moment, and then angrily smashed the water glass in his hand on the table.

At this time, all the map screens, communication signal interfaces, all turned into a cute blue fat man smiling pattern.
