"The question is how?" Chu Fan frowned and said, "Those things have protective shields. ”

Some experts on TV have already said that the protective shield of the alien mothership spaceship is about 1000 meters outside the main body, and the protective shield of the disc battleship is about 100 meters outside the main body.

It is already known that alien war machines have protective shields, and after the disc warships enter the atmosphere, humans still launch surface-to-air missiles, but the missiles are still stopped by the protective shield.

"There are already speculations!" Margarina recounted what she had heard: "They thought that the aliens' shields must need energy support, and that a saturation attack could break their shields. ”

When the Claude Disc Battleship approached the Earth, the outer space railgun that humans had previously built in Earth orbit had already launched an attack, but it was sucked into and destroyed as the Disc Battleship approached without a few shots.

Not only are the railguns that have been built with great expense and painstaking work, but even the satellites are sucked into the area where the disc battleship is close, and then crash into the protective shield and become space junk.

If the disc battleship rushed down the atmosphere, if there is anything beneficial to the earth, it is probably to help mankind carry out a space junk cleanup, and take the space junk into the atmosphere and then burn it up.

From a bird's-eye view, near the area where the disc battleship floats, some of the previously camouflaged military installations on the surface have been opened, and some of the unique gun barrels have been extended, and they are performing an action of charging, followed by a thick energy blast being punched out.

Lin Bin and the others at the base, they just heard a series of loud noises, and then saw the ground facing the sky to stimulate thick rays one after another, and the target was of course the alien disc battleship floating above the city of New York.

It was not only the base where Lin Bin was attacked, but at least seven nearby places that fired at the disc warship over New York City.

In an instant, at least two hundred and thirty energy rays hit the disc battleship one after another, and the energy rays reached about a hundred meters from the disc battleship and were stopped again by the protective shield.

"See!" Margarina pointed ahead, "This time the shield glows greener and lasts longer. Prove that attacks work! ”

It's about the effect of consuming alien energy, not really having a killing effect on the disc battleship.

Commands everywhere probably came to a similar conclusion, and as a result, a large number of missiles were fired from the ground into the sky, and their targets were still disc warships.

"That wave of attacks just now, it seems to have pushed that guy dozens of meters?" Chu Fan touched his chin and said, "I don't see what propulsion device it has, the floating technology is anti-gravity?" ”

"Attacking to drain their energy certainly has an effect." Lin Bin squinted his eyes and looked ahead: "It's just that the world's arsenal has been exhausted...... It may not be possible. ”

If human beings are still trapped on Earth, even if there are some activities in outer space, they cannot carry out long-term and long-distance manned space travel.

This time, the Claudes who came to Earth as invaders came from an unknown number of light-years away across the cosmic sea.

As long as the distance reaches the unit of light years, the voyage will pass through no place where there is no supply, that is, the cosmic space belt. The energy they use is definitely not the inefficient and high-consumption method of human beings.

The sound of explosions came from afar, and I don't know how many surface-to-air missiles were fired at the disc battleship, but they still failed to break through the protective shield to effectively damage the disc battleship, but repeatedly activated the protective shield and created a flash of bright light, leaving some smoke behind.

Lin Bin squinted his eyes, and those bright lights were very dazzling although they were short-lived.

The energy cannons on the surface are also firing continuously, and the time interval between each one is about three minutes or so?

In addition, some traditional artillery and firearms have also joined the attack, and they can also activate the shield of the disc warship when they hit the physical bullets.

In the face of the almost crazy firepower output of the earth's humans, the Claude people still did not react.

However, the disc battleship did not react in any way, and it made the hearts of human beings continue to sink.

If the aliens reacted, or even fought back violently, humans would be more comfortable, proving that human attacks were still a threat to them.

The aliens' complete ignorance proves that human attacks are not even an itch?

The heavy fire on the human ground lasted for about fifteen minutes, first no more missiles were fired, then the surface energy cannon stopped firing, and then all kinds of artillery and guns also stopped attacking.

The air base where Lin Bin is located used to be unmanned attack planes that have accelerated and then lifted off, and they will hover and cruise in the nearby airspace, waiting to form a formation.

"Didn't launch a nuclear bomb this time?" Mo Xi looked confused: "Shouldn't it be a nuclear bomb?" ”

"You idiot!" Lincoln choked angrily: "The greatest power of a nuclear bomb is radiation damage, and it is useless against an alien battleship with a protective shield!" Do you need a nuclear bomb to deal instant explosion damage? ”

There are still some weapons that are not so powerful to nuclear bombs. And the biggest threat of a nuclear bomb is indeed radiation damage, that is, the subsequent continuous damage to living beings.

Mo Xi touched his head and hesitated, "Is that so?" ”

Except for Eve, the rest of the people were already wearing anti-pressure suits under Lin Bin's signal.

The unmanned attack planes that have been assembled are leaving the sky above the base with a whistling sound, giving up the airspace to the manned fighters who are about to take off.

All over the world, at latitudes of day and night, there are aircraft taking off from air bases one after another.

Lin Bin's plane is an F22, but this F22 is not the original, it is an improved version of the "virtual race" technology obtained by human beings.

There are improvements in the energy system, propulsion system and fire system, and it is more obvious that there are two more energy cannons for hand-to-hand combat, which is no longer the type of physical bullet, but the main weapon is still various types of mounted air-to-air missiles.

The whistling sound in the sky was very dense, and when the ground looked at the sky, a large number of manned and unmanned fighters could be seen forming a formation, and the people watching this scene did not cheer, but were extremely heavy.

"Unmanned attack opportunity first!" Melly's voice reached the ears of the formation members through the contact device: "The main thing is to lure those dog mongrels to send out an engagement force. ”

It was a military operation bordering on desperation, with great risks to be tested.

If the aliens send troops, at least it proves that they are not completely ignoring humanity.

Once the aliens are still not reacting, then ......
