Bian Ge said without hesitation: "There must be some secret model, the beam is several times thicker than the alien battleship, it's not a secret weapon." ”

Ye Han turned his head again and asked, "Old Qi, you don't have any impression at all?" ”

"No, absolutely not!" Qi Haifeng shook his head repeatedly, "I've never heard of this kind of weapon. ”

Long Jianguo had an idea: "Where did this signal come from, or is it the one just now?" ”

"Yes."

"For the above, there should be an explanation, right?" Long Jianguo said.

"I can't say for sure." Ye Han shook his head, "It's more convenient to have a commentator directly." ”

"Then what about asking Beiyuezhou directly?" Long Jianguo asked unrelentingly.

"You can try." Qi Haifeng said, "I'm afraid that Beiyuezhou won't have time to answer us." ”

"Then let's try it too." Ye Han said.

The main force of the fleet is gone, the aircraft carrier group has fled back, and the super cannon has been exposed, and Beiyuezhou should have nothing else to do at the moment except to guard against aliens.

Qi Haifeng's fingers flew up and down, and he quickly nodded: "Send it out, wait a minute." ”

Everyone's eyes fell back on the screen, and after the super cannon destroyed dozens of alien warships, the remaining warships quickly turned.

The speed of the alien battleship is too fast, it is not so easy to slow down, and turning to dodge is actually retreating.

The Moon had no intention of sparing the enemy, and after about half a minute, the Super Bale opened fire again, destroying half of the remaining enemy ships.

There were a dozen or so remaining alien warships, and they fled like frightened birds, flying out of effective range before the super-cannon could fire again, and joining up with the following alien fleet.

"It's a pity." Ye Han sighed helplessly, "If only I could lead them all to the moon......

Probably afraid of human nuclear weapons, the aliens learned wisely this time, and after discovering the human fleet, they did not rush up, but completely separated the fleet, pressing up in waves, with as few as a dozen ships and as many as two dozen ships in each wave.

By the time the supercannon fired, at least half of the enemy ships were still out of range of the supercannon, and if it weren't for the cover of the carrier group, the supercannon would certainly not have fired so early.

Qi Haifeng said: "It's not bad to kill so many." ”

The combined fleet has fought out more than a hundred enemy ships, the super cannon has killed dozens more, and there are only a dozen alien striker fleets left, but there are almost two hundred alien warships behind.

The enemy has suffered heavy losses but the main force is still there, and the human race has exhausted its last strength, even if the Helicarrier sets sail again after replenishing the fighters, it will only be the most desperate struggle.

"What about the rest?" Bian Ge asked.

No one answered, and all eyes fell on the alien ship group, watching them gradually fly towards Earth.

Qi Haifeng said in a low voice: "Now it's up to us to see if the earth can withstand it." ”

"Resist? Are you kidding me? That's more than 200 warships! Bian Ge was indignant, and the faces of the others were not good-looking.

Everyone knows what the alien fleet means, it is not only more than 200 warships, but also tens of thousands of alien fighters, no matter how tight the defense of the earth is, it will not be able to block so many enemy ships and enemy planes.

Qi Haifeng sighed: "What about more than two hundred? This is not the case anymore. He called up a diorama of the Earth, which was constantly rotating with shiny points of light.

"What is this?" Ye Han asked.

"The laser air defense network of the earth, each point is a laser cannon." Qi Haifeng said.

Ye Han looked carefully and found that there were shining points of light everywhere, whether on the ground or on the water, and there were countless illusions.

But can laser cannons stop aliens?

The natural advantages of air-to-ground are not as simple as words.

"It's all gone." Ye Han said dejectedly, "What should you do, what should you do." ”

At the current speed of the alien fleet, it will take at least a whole day to fly to Earth, so there is no need for everyone to huddle in the bridge and wait.

"Wait a minute!" Qi Haifeng waved his hand violently, "There is news of a super cannon!" ”

"So fast?" Ye Han simply couldn't tell his ears.

"It's not a reply from Beiyuezhou...... Oops, don't care where it came from! Qi Haifeng said.

"Then what are you waiting for, hurry!" While speaking, Ye Han was already looking at the home screen.

Qi Haifeng immediately transferred the message he had just received to the main screen, and the earth on the main screen was immediately replaced by the moon, and three conspicuous points of light appeared on the moon.

Ye Han tightened his brows: "These three places...... It looks like it's all craters! ”

"It's a crater." Qi Haifeng said, "The super cannon is in the crater, this thing is called ...... Well? ”

"What are you peeking at yourself? Put it all on the home screen! Ye Han said dissatisfied.

Qi Haifeng shrugged, pointed his finger, and immediately many more text explanations appeared on the screen.

I don't know if I don't look at it, I don't know if I look at it, the so-called super cannon is not the kind of large laser cannon that everyone thinks, but a laser cannon array spelled out with ordinary laser cannons!

Beiyuezhou selected three internally flat craters on the surface of the moon, first laid a large number of cables at the bottom of each crater, and then placed a large number of laser emitters, each laser covers an area of 0.82 square meters, plus the necessary maintenance space, exactly one square meter.

The first array, one kilometer in diameter, contains 785398 small lasers and more than 20 nuclear reactors that provide electricity for the array.

Although the effective range of each laser is only a little more than five kilometers, after nearly 800,000 lasers are combined, the effective range can reach more than 70,000 kilometers!

The No. 2 array has a diameter of 1,200 meters, which is only 200 meters more, but the number of lasers has reached 1.13 million, with an effective range of more than 90,000 kilometers and a maximum range of 120,000 kilometers.

The largest No. 3 array has a diameter of 1,500 meters, and it is planned to place more than 1.76 million lasers, almost the sum of No. 1 and No. 2, and the range is expected to reach 180,000 kilometers.

But the No. 3 array needs too many lasers, even if Beiyuezhou goes all out, it can't get so many lasers, so far, the No. 3 array has just completed a small half, and the lasers that have been in place are about 450,000.

Due to the proximity of the aliens, the construction of the No. 3 array had to be temporarily stopped, and the commissioning of the existing array was completed before the arrival of the aliens, although it was far from the planned range, but the effective range of 40,000 kilometers was still available.

If the No. 3 array is completely completed, the moon will not need to consume the fleet at all, as long as the alien fleet is lured to the vicinity of the moon, the alien fleet can be cleaned up with the laser cannon array alone.

It is a pity that the completion of the No. 3 array is far away, and the No. 1 and No. 2 artillery positions are not in this direction.
