After reading the information, everyone stared at each other for a while. Finish. The feeling of a dog, hundreds of thousands of lasers at every turn, is this still the moon?

Although the cost of building a laser array is not as high as that of a capital ship, the power of the laser array exceeds that of all active capital ships, and it can even be said that it is the strongest weapon that mankind currently has, and even nuclear weapons have to stand aside.

And in order to facilitate maintenance, how simple is it in Beiyuezhou, all lasers are the simplest in structure, and even the control equipment below is much more sophisticated than lasers...... Having said that, the control equipment is the most critical foundation of the laser cannon array.

Think about it, if the control equipment is not precise enough, how can more than 700,000 lasers be aimed at targets tens of thousands of kilometers away at the same time? How can you let so many lasers fire at the same time and finally hit a target point together?

Coordination issues alone can be a headache.

Another disadvantage of this thing is that it must be fixed to the ground, if it can be mounted on a battleship...... Well, you don't need to be on a non-equipped battleship, you can get a few more battleships to get a salvo to achieve the same effect.

But in this situation, it's really hard to say when Beiyuezhou will be able to save so many warships.

Ye Han noticed that the construction of the No. 1 array was not long after the departure of the raiding fleet, and it seemed that at that time, the military began to take precautions and prepare for aliens to hit the earth.

He suddenly came to his senses: "You say, is there such a super cannon on the earth?" ”

"There should be, right?" Xiao Yuan said cautiously.

Don't look at him as the most talkative, but here he has the lowest military rank, so today is particularly low-key.

Unexpectedly, Ye Han suddenly shook his head when he asked the question: "I also hope to have it, but the possibility is too small." ”

"Why?" Xiao Yuan was puzzled.

"Because of the vacuum." Ye Han said, "The surface of the moon is vacuum, there is no wind, no rain and no fog, and the laser can always be there; The earth is different, the laser must have something wrong after a long time, even if there is, it is impossible to be so directly placed as on the moon, I think the possibility of dispersing the gun positions and firing in a concentrated manner is relatively high, as long as there are enough gun positions to fire at the same time, the power is definitely not worse than these arrays on the moon. ”

"That's great!" Everyone suddenly had a little hope in their hearts, looking forward to the laser air defense network to block the aliens.

Ye Han said: "If it's okay, don't wait and see, let's go back first, Lao Qi, if there is any situation, notify us in time, if there is anything to help, just say." ”

"Don't worry." Qi Haifeng immediately agreed.

They say what they should do, but the alien fleet is flying to the earth over there, and who doesn't feel like they're carrying a big rock in their hearts?

As long as the consciousness is still clear, one cannot help but worry about the fate of the earth.

Everyone spent a long day in deep depression, and the next day before they could do anything, everyone involuntarily rushed to the bridge.

Ye Han was a little earlier than scheduled, but when the bridge door opened, he was stunned to find that everyone else was already waiting in the bridge.

He slowly floated into the bridge and waved at everyone: "Lao Qi, how is the situation?" ”

"Just past the synchronous track, it's slowing down." Qi Haifeng said.

Ye Han casually found a position: "What is the reaction of the earth?" ”

"Nothing special, the railgun array should be ready." Qi Haifeng said, "Aliens are quite shrewd, and they play the game of dividing troops. ”

"Division? Tempting. Ye Han turned his head to look at the screen.

More than 200 enemy ships have been divided into several groups, approaching the earth from different directions, the farthest is still near the synchronous orbit, and the latest is close to the laser satellite.

Laser satellites have long been in full swing, and a series of satellites with wing-like photovoltaic panels, the angle and direction are surprisingly consistent, and they are so neat that they look imposing.

"Definitely." Qi Haifeng said.

Ye Han suddenly found that there were alien spaceships in all directions of the earth, but there was not a single enemy ship in the direction of the moon, and he couldn't help but point to the screen and said, "Is this to make the super cannon scared?" ”

The distance between the Earth and the Moon is 380,000 kilometers, and the range of the planned No. 3 laser cannon array is only 180,000 kilometers, so there is no need for aliens to hide so far.

Qi Haifeng smiled: "I'm scared, but it has nothing to do with the moon." ”

Ye Han glared angrily: "Sell less guanzi, hurry up." ”

Qi Haifeng agreed, pointed to the screen and said, "Beiyuezhou not only created a super cannon, but also a three-level defense system. ”

"What's that?" Ye Han straightened his ears.

"Three-tier defense system." Qi Haifeng repeated, "To put it simply, three space stations equipped with super cannons were built between the earth and the moon, using the cannons on the moon to protect the first-level space station, and then using the first-level space station to protect the second-level space station, and the lowest space station covered the earth." The aliens wanted to go this way, but they were shot and then retreated. ”

A top-down three-level firepower system immediately appeared in Ye Han's mind, and he couldn't help but be a little stunned: "Why don't you install this technology on a battleship?" ”

"You're going to ask me." Qi Haifeng said, "That's how much information I get. ”

Long Jianguo said: "There may be some flaw. ”

Ye Han was slightly stunned and nodded thoughtfully.

At this time, the alien battleship finally flew near the satellite artillery array, the hatch of the ship was wide open, and the ice-white alien fighters floated out like butterflies wearing flowers, and then pounced on the satellite light cannons in groups.

As soon as the group entered the firing range, the satellite light cannon automatically opened fire, and one after another lasers flew out of the barrel, destroying the enemy planes one by one.

Not to be outdone, the alien aircraft group vigorously launched insect bombs at the satellite.

The distance between the two sides in a straight line was less than a hundred kilometers, and it didn't take long for the insect bomb to fly over this distance. Satellites are not as good as drones, they don't know how to dodge at all, they are either smashed by insect bombs on the spot, or they are splashed with acid by acid bombs, and more are destroyed by light bombs.

Some of the insect bombs failed to hit their targets and continued to fly past the satellite light cannons to Earth, where they burned up in the atmosphere after a short time.

The insect bomb is too small to break through the atmosphere at all.

The satellite defense line is too fragile, and everyone watched the defense line go from existence to nothing, being beaten to pieces by a group of alien fighters, and everyone was holding their breath.

Bian Ge was angry and hateful: "Who came up with the bad idea?" "If you have the time and materials to build satellites, wouldn't it be good to build something else?

No one answered, Bian Ge wanted to say more, the surface of the earth suddenly appeared one after another shining bright spots, and in the blink of an eye, countless beams of light rushed from the ground into space, instantly penetrating the alien warships in the sky.

The alien group that had just won turned into headless flies, and the ground immediately replenished with a wave of artillery fire, sweeping away all the alien fighters.
