One Thousand One Hundred and Three Alien Revenge

Bian Ge was dumbfounded and speechless. He suddenly came back to his senses and asked, "What is the distance?"

Qi Haifeng glanced at the screen: "Satellite guns are 500 kilometers, and enemy ships are 600 kilometers."

"So close?" Bian Ge looked disappointed.

Qi Haifeng glanced at Bian Ge: "Then how much do you want?"

"At least 30,000 to 50,000 kilometers?" Bian Ge said without hesitation.

"30,000 to 50,000?" Qi Haifeng rolled his eyes, "It can directly hit the synchronous orbit, why not just destroy the alien fleet..."

Before he finished speaking, another wave of lasers was launched from the ground, aiming directly at the alien fleet at an altitude of 1,000 kilometers, and successfully destroyed three enemy ships.

The alien fleet was immediately in an uproar, so the alien warships turned around and ran away.

The aliens reacted quickly, but the laser air defense network reacted even faster, firing into the air wave after wave, killing more than a dozen enemy ships one after another.

Including the enemy ships killed in other directions, fifty or sixty alien warships were killed in such a short time, and the results were brilliant.

However, the range of the ground air defense network is indeed far inferior to that of the super cannon. After the aliens raised the orbital altitude to 2,000 kilometers, the laser from the ground hit the enemy ship again, but this time the enemy ship only emitted a puff of green smoke and then quickly fled, and the laser from the ground had to stop.

Everyone on the Donghai felt like they had escaped a disaster. Long Jianguo looked at Qi Haifeng at the first time: "Is this defended?"

Qi Haifeng nodded: "It should be."

"Great!" Bian Ge waved his fist.

After being worried for so long, I finally heard good news.

Although the others didn't say it, they were also relieved in their hearts.

What everyone is most worried about is the fall of the Earth. Now, the Earth has blocked the alien fleet. No matter whether the Earth or the Moon is something the aliens can plot against, they can only think about Jupiter. Ye Han is eager for them to get to Jupiter. The nuclear bombs in the center of the Earth are lonely and waiting for the aliens to come.

Thinking of this, Ye Han suddenly remembered something: "Old Qi, are there two alien spaceships heading for Jupiter?"

"Yes, that's the case."

"Where are the spaceships?"

"You asked the right question... I don't know!" Qi Haifeng rarely joked.

Ye Han also laughed: "Okay, if you don't know, then don't know. If the aliens dare to go up, they will definitely dare to bomb Jupiter."

A few nuclear bombs can't destroy Jupiter, but it is absolutely no problem to destroy the planetary engine placed in the center of the Earth. At that time, Jupiter will stay in front of the Earth forever.

Use Jupiter to hit the Earth? Wishful thinking!

The crisis on Earth was resolved, and everyone relaxed. They chatted about everything before leaving the bridge.

There was still more than a month of voyage ahead, and Ye Han planned to wait until the aliens left Earth, then re-inject hibernation hormone and sleep all the way back to Beiyuezhou.

His little abacus was very loud, but he didn't expect that he was suddenly woken up by Qi Haifeng when he was sleeping soundly that night: "Master Ye, something happened!"

Ye Han's sleepiness disappeared immediately: "What's wrong?"

"Alien fleet, they are flying towards L4 and L5!"

Ye Han's mind paused for a moment, and suddenly realized what Qi Haifeng said: "Lagrange point... asteroid?"

This news was like a basin of ice water poured on his head, and the cold penetrated from the epidermis to the bones.

Qi Haifeng's face was as gloomy as water: "It should be."

Ye Han quickly climbed out of the sleeping bag: "Is there any news from above?"

"Not yet."

"Is it reported to the top?" Ye Han quickly put on his clothes.

"I've reported it," Qi Haifeng said, "but I think the higher-ups should have known about it a long time ago."

"I'll be there soon." Ye Han said as he jumped out of the dormitory, swiftly flew through the corridor, and soon arrived at the bridge.

The main screen had long been replaced with a bird's-eye view of the Earth-Moon system. At this time, the alien fleet was divided into two, one flying to L4 and the other flying to L5.

Lagrange points are also called libration points. In layman's terms, they are the gravitational equilibrium points between two large celestial bodies. There are five of them in total.

L4 and L5 of the Earth-Moon system are located in front of and behind the moon, respectively, and are on the moon's orbit. Any point connected to the earth and the moon can form an equilateral triangle.

The most important thing is that there are asteroids at these two points!

(ps: I can't find any information about this online. There should be no asteroids at L4 and L5 on the Earth and the Moon. This is for the plot, please don't worry too much - this paragraph is not included in the paid word count!)

L4 and L5 are both stable gravitational equilibrium points. These asteroids are not a problem at all in normal times, but if aliens obtain these asteroids, it will directly threaten the safety of the Earth.

Ye Han stared at the screen for a long time before whispering: "How long will it take to get there?"

"At the current speed, L4 will take another hour, and L5 will take a little longer, between one and a half and two hours." Qi Haifeng said.

"Is there no movement above?" Ye Han asked unwillingly.

Qi Haifeng shook his head: "Too far."

Ye Han repeated blankly: "Yes, too far."

Whether it is the Earth or the Moon, the distance to these two points is nearly 400,000 kilometers. It takes at least two days to fly over this distance. Even if you set off immediately, you can't catch up.

After watching for a while, Ye Han shook his head and said: "It should be fine."

The asteroids at the two points are not that many when added together. Besides, the air defense network of the earth even forces aliens to retreat, so what's the big deal about dealing with a few asteroids?

A flashing cursor suddenly appeared on the screen in front of Qi Haifeng, and he immediately said: "There is news from the top!"

Ye Han immediately floated to Qi Haifeng's side: "What did they say?"

Qi Haifeng clicked on the icon and scanned it at a glance: "Nothing special, just reminding all units to be prepared or something... God!"

"What's wrong?"

Qi Haifeng raised his head and looked at Ye Han with astonishment: "The top said that several asteroids will soon reach the earth, the smallest is two or three kilometers, and the largest is about eight kilometers."

Ye Han was in a bad mood: "How many in total?"

"It is said to be six."

Ye Han turned back and stared at the alien fleet: "It must be aliens!"

There are many small celestial bodies near the earth, but most asteroids are less than three meters in size, and those over three meters are rare.

It's not that there aren't some larger asteroids, but it's definitely not normal. It's hard to have one at a time, so how come there are six at the same time now?

The only explanation is aliens.

And Ye Han thought of Ganymede.

When Ganymede was destroyed, the interception campaign had been over for more than a month, but the actions of the North Sea fleet could not be hidden from the aliens.

Although the aliens were in a state of decline, they were still an interstellar race after all. It was impossible for them not to understand the intentions of the North Sea fleet. If there were no other way, the aliens on Ganymede would have run away long ago.

So, the aliens may have deliberately brought a few asteroids after discovering the intentions of the North Sea fleet, in order to repeat the destruction of Ganymede and retaliate against humans in kind... But what does it mean that the alien fleet went to L4 and L5? Are these two places related to the asteroids that are about to arrive on Earth?
