The moon, falling to the top of the mountain.

Ou Zhanpeng and Xu Qing walked side by side, putting their helmets together from time to time to whisper.

There are many people who are stranded on the top of the mountain like this, and everyone gathers together in twos and threes, or talks loudly, or whispers.

A rapid siren sounded on the radio, and everyone immediately retreated to the edge of the hilltop until the radio siren stopped.

Ou and Xu were no exception, the two of them found a stone to sit on it, snuggled quietly together, and looked up at the blue planet on the sky.

The giant airlock in the middle of the hilltop slowly opened, and a moment later, there was a muffled thud, and a battleship module suddenly jumped into the sky.

The maglev base of the lifting module quietly separated, slowly falling out of the mountain, until it was close to the ground, and the recoil rocket ignited and slowed down, allowing the base to land safely.

The commandos who had been waiting there for a long time swarmed up and dragged the base back to the base.

As soon as it left the danger zone, the base immediately launched the second module, then the third, then the fourth......

"How many ships are this?" Xu Qing asked softly.

Ou Zhanpeng snapped his fingers: "The tenth."

"That's fast!" Xu Qing said

"yes, that's fast." Ou Zhanpeng agreed.

In the blink of an eye, it was six months, and under the strong pressure of the alien species, the countries of the earth worked overtime to prepare for the war, eager to use one minute as two minutes, and the propaganda machine was even more open to talk about aliens, and it was no longer as secretive as before.

The base initially built at a rate of 1.4 warships per month, but as the production capacity increased, the construction rate became faster and faster, and finally reached two ships per month.

As a result, the dozens of people in the expedition team were simply not enough, and more people had to be drawn to join, and the vast majority of them were old acquaintances who had trained at the base.

Originally, Xu Qing should have been a member of the ship, but because of Ou Zhanpeng's relationship, she received special care and stayed at the Luojian Mountain base.

This made her feel like she had betrayed the team, and she was very uneasy at the bottom of her heart.

But there is no way, Ou Zhanpeng's current position is too special, in order to let him work with peace of mind, it is impossible to arrange Xu Qing to carry out the expedition mission.

Ou Zhanpeng originally planned to toss for a while, let Xu Qing conceive a child, and take advantage of the loopholes in the rules - no matter how short the military is, it will not arrange pregnant women to perform dangerous tasks.

But after tossing back and forth for several months, there was no movement at all, which made Ou Zhanpeng depressed.

Deadlifted Xu Qing for a comprehensive examination, and the results made him even more depressed: the doctor said that his genes were different from ordinary people, and it was difficult to have children normally!

It's a problem with genes for a long time, the problem is that his own genes were changed before he was born, and now there is no way to change it back, the only feasible way is to repair the problems in the genes by manual intervention, and then make Xu Qing pregnant by artificial assistance.

In other words, without Xu Qing's consent, Ou Zhanpeng's plan was completely ruined to achieve his goal.

Fortunately, it is more user-friendly above.

In the distance, a very uninteresting person jumped up: "Hey, I'm really convinced, where are you two so tired?"

Ou Zhanpeng glared at the Lingxiao brand light bulb viciously: "You hurry up and find one yourself, don't you know?" ….

"Forget it, I'm not in the mood." Ling Xiao sat directly on the ground and tilted his head to look at the earth, "Have you heard, the next one will not be an expeditionary ship, and it plans to build two space carriers to be the core of the fleet."

Ou Zhanpeng was a little disappointed: "This is the plan to let you go to the Helicarrier?"

"Yes." Ling Xiao said, "Before the battleship was built, I was given the position of aviation commander and let me command the fleet...... Well, what do you think I'm going to command?"

"Isn't it that it hasn't been built yet, just in time for you to learn." Ou Zhanpeng was even more disappointed, "You still have a chance, I have no hope at all."

The Aerospace Helicarrier is not an expeditionary warship, with a standard crew of more than 3,000 people and a full load of nearly 5,000 people, but such a large warship still does not have him

Location.

"Cut!" Ling Xiao pouted disdainfully, "Forget it, you want to keep a lot of it, but the only ones who can stay are the two of you, don't leave me here to show off."

"What am I showing off to you?" Ou Zhanpeng sighed and diverted the topic, "I don't know how to build a space fleet and bring up the surface fleet!"

Ling Xiao glanced at him, "Isn't it good?"

Ou Zhanpeng shook his head: "I don't know if it's good or not."

He had seen many fleets in his dreams, but he had not yet discovered a single civilization with motherships as the core of their fleets. But from the perspective of historical experience, the space fleet and the surface fleet do have something in common, which is very tangled.

Xu Qing chuckled: "He is idle, obviously a eunuch, the emperor's heart every day!"

Ou Zhanpeng immediately smirked: "What am I, don't you know better than anyone else?"

Xu Qing's face turned red, and she smacked the shameless Ou someone: There are still outsiders here, what nonsense are they talking about?

Ling Xiao also expressed deep dissatisfaction: "You two are almost done!"

Ou Zhanpeng didn't blush at all: "If you can't get used to it, find one yourself, don't leave me here all day as a light bulb!"

Ling Xiao didn't move at all: "There is no humanity of the opposite sex, you!"

Ou Zhanpeng laughed: "You just met me?"

Xu Qing was angry, grabbed the soft flesh on Ou Zhanpeng's waist, and twisted it fiercely.

Talking and laughing, the last module was launched, and everyone walked back in twos and threes, and before entering the base, Ou Zhanpeng suddenly received a notice from the base, asking him to go to the conference room immediately.

He sighed helplessly: "Notify the meeting, you two go back first."

Several people separated, Ou Zhanpeng rushed to the conference room as quickly as possible, and Xie Yu and several other high-level officials of the base were already waiting here.

"It's up to you." Xie Yu said.

"Just came down from the top of the mountain." Ou Zhanpeng explained.

Xie Yu shook his head and smiled bitterly: "Hey, what do you think, isn't it just to launch the battleship module, what's there to see?"

"I don't know." Ou Zhanpeng shrugged, "But my daughter-in-law likes it."

was forcibly fed a mouthful of dog food by someone Ou, and Xie Yu immediately stopped talking.

Single dogs have no human rights!

The door opened, Gong Yiding entered the conference room, and everyone immediately put away their jokes.

"I just received the news that the alien fleet has stopped in the asteroid belt and is pushing the asteroid in the direction of the Earth, and it is expected that the first batch of asteroids will arrive on the Earth in August today, and it orders us to draw up a plan to deal with the crisis as soon as possible!" ….

Xie Yu's eyes widened in surprise: "Such a big thing, let's make a plan?"

"Brainstorm ideas, other units should have received similar notices." Gong Yiding said.

"What else can I do, I must not let an asteroid hit the earth, and the easiest thing must be to bombard it with a warship." Zhu Yuhan said.

Lao Zhu stayed at Guanghan Station to preside over the work, and later all kinds of resources were inclined to Luojian Mountain, Guanghan Station has in fact lost the role of a scientific research station, Yanjing simply merged Guanghan Station into Luochuan Mountain, and now Guanghan Station has become a water supply place for Luochuan Mountain, and only five or six people are left to maintain buildings and equipment.

Gong Yiding was noncommittal, and turned his head to look at Xie Yu and Ou Zhanpeng: "What do you two think?"

"I don't think it's appropriate." Xie Yu said.

"I don't think it's good either." Ou Zhanpeng agreed, "Let me first declare that we are not right about things, now is the critical moment of combat readiness, every warship to equip consumes a huge amount of resources, and the precious ammunition consumed on the asteroid is really worth the loss."

The cost of a bullet is a few cents at most, and a shell is a few thousand dollars at most, but missiles are different, this thing is at least hundreds of thousands of dollars per shot, let alone mushroom bullets.

It's still on the ground, and if you send them to space, it's not that simple.

At a payload of 4000 meters per kilogram, the cost per gram is about 5 meters of knives, and each bullet weighs 12 grams

calculated, it is a full 60 meters of knife, which is more than 430 soft sister coins.

One magazine of 30 rounds is 12,900, and five live magazines are 64,500.

One small-caliber shell 320 grams, about 11,500.

One 155-mm grenade weighs 50 kilograms and is about 1.8 million.

Not to mention missiles, it's simply a burn of money!

Now that the military factory in the lunar industrial zone has long been put into production, the cost of ammunition has dropped by more than half, but the cost is still much higher than that on the ground, and the production capacity is limited, that is, it can barely meet the needs of the fleet, how can there be excess ammunition for asteroids?

Zhu Yuhan spread his hands: "I can't think of any other way, or don't you use lasers?"

Gong Yiding immediately shook his head: "The efficiency is too low."

"Where's the electromagnetic cannon? It's cheap."

Gong Yiding finally nodded: "Write this down first, alternative."

There are mines on the moon, and although the production capacity in smelting is always not high, it is still no problem to meet the electromagnetic gun.

And the earlier it is intercepted, the less force is needed, if the asteroid can be intercepted in the orbit of Mars, even if it is a random finger, the asteroid can be deviated from the earth by 108,000 miles.

Therefore, the battleship set off in time, and even if it only hit the asteroid with a steel ball the size of a soybean, it could complete the interception mission.

Ou Zhanpeng thought for a while and said, "Stationmaster, where is the enemy ship? Gather together, or disperse?"

Gong Yiding tapped the terminal, and a map of the solar system appeared on the screen behind him: "Here, here, and here, traces of alien spaceships have been found."

"That's at least four directions." Ou Zhanpeng frowned, "At least one warship is needed in one direction, and it is best for two to coordinate with each other...... If we send all the warships, will we be able to return to Earth before the enemy ships arrive?"

"Yes, it's easy to leave Earth, but it's hard to come back!" Xie Yu said. ….

The solar system is a system in constant motion, and it is impossible for either a natural celestial body or a man-made vehicle to sail in reverse after braking.

Not only does it take a lot of time, but it also consumes a lot of fuel, and unless there is a revolutionary breakthrough in human propulsion technology, it is impossible to turn around and return to the sea halfway.

The most reliable solution is to fly to another planet and use the planet's gravitational pull to reverse direction.

Gong Yiding and Zhu Yuhan were very aware of this, and both of them shook their heads at the same time, denying the idea.

Although the enemy ships are still far away, at this juncture, all human warships must defend the earth, otherwise once the enemy army arrives, the consequences will be unimaginable.

There was silence in the conference room, and a few people racked their brains, but couldn't think of a suitable solution.

"Why don't you call a few more people and brainstorm ideas?" Xie Yu reluctantly suggested.

Gong Yiding shook his head: "Not for the time being, wait for the above arrangement...... Adjourned!"

"Wait!" Ou Zhanpeng suddenly stopped, "I have an immature idea."

"If you don't care if you're immature, just say it." Xie Yu urged impatiently.

"Say it." Gong Yiding handed over an encouraging look.

Ou Zhanpeng tugged at the corners of his mouth: "You say, if you put a shield on the missile, can you directly hit the side of the asteroid?"

"It's fine, but it's certainly not that simple." Xie Yu instinctively felt that this idea was unreliable, but he really couldn't say what the problem was for a while.

"Straight hit?" Zhu Yuhan was stunned, "With such a high relative speed, can the shield withstand it?" I think it's better to do it in a non-contact way."

Contactless?

Zhu Yuhan's original meaning still refers to various shipborne weapons, but this sentence is like a key, and Ou Zhanpeng's mind suddenly brightens: "It makes sense, the impact is too unreliable, stationmaster, I heard that the artificial gravitational force and the protective force field are similar in principle, since the gravitational force can be generated within a certain range, can the repulsion force be generated in the same range?"

Gong Yiding was stunned: "You mean, use the force field to repel the asteroid and change the orbit of the asteroid?"

"Yes

That's what I mean!" Ou Zhanpeng nodded vigorously.

"Eh, that's a good idea, that's good!" Xie Yu agreed loudly, as if he had come up with the solution.

Zhu Yuhan said worriedly, "Can this gravitational force be changed to repulsion?"

"I don't know." Gong Yiding said, "Even if you can't generate repulsion, you can change the orbit of an asteroid by directly using gravity!"

"Hey, what are we talking about, don't we just ask the experts?" Xie Yu said.

Just do it, Gong Yiding immediately contacted the headquarters, and quickly got a reply: "There is no problem in theory, experiments are being arranged!"

"Great!" Xie Yu said excitedly.

Just a few days later, the good news came from the ground, the first artificial repulsion prototype was successfully trial-produced, although the repulsion generated is not large, but multiple generators are arranged together, which can produce a strong enough repulsion force to change the orbit of the asteroid!

Not only that, but the people involved also planned to design a repulsive thruster to power the warship through the interaction between the thruster and the star.

However, although the idea is good, it cannot be realized in a while, and it is important to solve the problem of asteroids first.

As a result, the relevant design was immediately put on the agenda, and only a few days later, Luoshipan received a very special set of spacecraft drawings.

It has eight repulsion generators mounted on a robotic arm on its hull, which can exert influence on eight targets at once.

In addition to this, two small-caliber electromagnetic machine guns were installed on the ship, which facilitated the use of influence on small celestial bodies outside the repulsion range.

Although the design is good, it is just necessary to overcome the precious printing resources of Luojian Mountain, so that Gong Yiding has made several reports in a row, asking for continued additional production capacity.
