Shortly after the task force left Hope City, Luo Yuan also started a curvature flight to leave Hope City after processing several documents. Happy; Wen; ＋

Nowadays, the earth environment outside is harsh, the extreme cold covers the earth, and the time for human beings to leave the underground and return to the surface is far away, and the material reserves and residual industrial systems entrusted to the underground cannot save a total of nearly five or six million people in Hope City and even the surrounding areas, let alone the reconstruction and development of civilization!

It is even difficult to reunite the surviving populations of the three nearby cities and establish a unified and efficient administrative system.

Fortunately, although the arrival of aliens has brought humanity to the brink of extinction, it has also left an entire ship intact.

And this is a huge spaceship, because the Boxing civilization technology is highly automated, so that the utilization rate of the spacecraft inside the spacecraft is pitiful, it can be said to be a luxury, especially in the habitation layer, perhaps considering the psychological depressive effect of living in a narrow space for a long time, its vertical height is as high as more than two hundred meters, almost occupying two-sevenths of the entire height of the spacecraft, and the diameter is an astonishing 1.5 kilometers long.

Among them, the central ecological park occupies the vast majority, and in terms of Boxing technology, this kind of ecosystem is already dispensable for them, and the air circulation system on the spaceship can automatically adjust the air finely, so that the air is always fresh and comfortable.

It exists only so that travel in space will not be so monotonous, and at the same time to avoid space syndrome.

However, for human beings who are struggling to survive at this time, it is undoubtedly too much luxury to think about these things.

If the botanical garden and some useless cabins are removed, the usable area of the entire spacecraft living area can reach more than 1.7 million square meters, and the usable space can reach 350 million cubic meters when multiplied by the height of up to 200 meters.

With the standard of two people living in every 3*3*3 space, then this residential area alone can accommodate 26 million people.

Of course, this is only ideal.

In terms of actual space utilization, it is impossible to be so high, but even a quarter of them have nearly seven million people, enough to fit all the remaining population of the earth today.

Compared to Hope City, Dawn City, Unity City and Victory City are all small cities, before the disaster, each city basically only had a population of more than one million, of which Victory City was only more than 900,000 because of its proximity to the wilderness.

After the disaster, the total number of people is probably less than 3 million, and the remaining population of Hope City is less than 5.4 million and less than 6 million.

However, before humans can move in, the spaceship living area must be renovated on a large scale, and some workers must be moved in first, and high-rise buildings with ultra-high floor area ratios must be built on the ship's living floor.

……

In less than ten minutes, his curvature flight speed was at its peak.

The last war with the Boxing people made a small breakthrough in his will last time, although it did not immediately reach 20 points, but it also made his curvature flight speed increase by leaps and bounds, from the original 150 kilometers per second to 1,000 kilometers per second in one fell swoop (modified above)

The spacecraft is 600,000 kilometers away from Earth, but at this terrible high speed, it is only ten minutes away, and even if you add the long start-up time before, it is only seventeen minutes.

I saw that the spaceship was rapidly enlarged in his eyes, and after a minute, he began to slowly reduce his speed. Not well, the space curvature bubble and his body went directly into the interior of the spaceship.

"Welcome, Captain."

Before entering the spaceship cabin to unravel the curvature bubble, the voice of Zhi Brain sounded softly.

Luo Yuan didn't have any accidents, with the detection ability of this spaceship, it was completely impossible to enter the interior without knowing it, he walked briskly towards the control room, and asked, "How are you doing?" ”

"Everything is in good condition, but the production area cannot be contacted, resulting in production not being able to be carried out, please arrange engineers for your Excellency the captain to rush to the overhaul!" Zhi Brain said softly.

"I see!" Luo Yuan was noncommittal.

This is a contradiction, once repaired, the core program of the brain is to automatically contact the production area to produce the quantum communication device, and then repair the communication device to keep the link with the Boxing, without repairing, the production area will not work, and the automated factory on the spaceship will be idle.

But this is only temporary, and when human beings gradually migrate in, and gradually become familiar with and understand the operation mode of these automated factories, even if they are separated from the automatic control of the intelligent brain, they can also produce normally, but the efficiency is reduced.

The wisdom brain is just a routine reminder, and then it is no longer reminded.

"Can this ship go to Earth?" Luo Yuan asked.

"Unfortunately, no, today's spacecraft has a total mass of 1.57 billion tons, which can only withstand an acceleration of 5.3 m/s^2, and the gravitational pull on the Earth's surface is as high as 9.8m/s^2, so flying to Earth will cause the spacecraft to produce subtle deformations and unpredictable consequences."

"How heavy is it?" Zhi Brain's answer made Luo Yuan frown slightly, this kind of quality was completely beyond his imagination, the mass of 1.57 billion tons was equivalent to 15,000 tons of 100,000 tons of aircraft carriers before the end of the world.

"The ship's weight comes from three parts, the ship's own weight, the supplies the ship collects, and the spare parts in stock.

The weight of the entire spacecraft is 110 million tons, the total mass of spare parts is 400 million tons, and most of the remaining weight comes from various collected materials, including pure water: 530 million tons, pure iron 180 million tons, pure copper 120 million tons......"

The ship's collection of materials is staggering, covering almost all the elements that can be found in the entire elemental table, with the largest amount being water, which accounts for one-third of the ship's total mass. Unlike in the eyes of human beings, water is only the source of life, in the spacecraft, in addition to supplying the needs of life, it is also the fuel for nuclear fusion, and it is also an important element for the synthesis of various organic matter and chemical raw materials, and its consumption is quite amazing during the long interstellar flight.

"And what about the little ship on the top floor?" Luo Yuan continued to ask, and as he spoke, he had already walked to the control room.

"If you're talking about the emergency escape spaceship, it can fly to Earth!" Zhi Brain replied.

Luo Yuan couldn't help but breathe a sigh of relief in his heart and asked, "Then how does it operate?" ”

"Its control system is my subsystem, as long as Your Excellency gives permission, it can intelligently control the flight?"

"That's good, by the way, give me a few copies of the comparison between Boxing and Chinese?" Before leaving, Luo Yuan remembered something and said again.

……

After a while, Luo Yuan took a stack of thick paper materials and came to the spaceship on the top floor, and after verifying the permissions, the spaceship hatch automatically opened.

"Your Excellency, Captain, welcome to you, I am the control system of the emergency escape spaceship No. 002, ready to serve you."

Luo Yuan walked into the control room, the layout of the control room here was exactly the same as the mother spaceship, he glanced at it, and said, "I'm going to Earth." ”

"Please enter coordinates?"

On the three-dimensional screen, the image of the entire earth flashes at once, as well as dense coordinate groups.

After this period of familiarity, he has also developed a certain understanding of this kind of three-dimensional imagery, which can capture the movements of the hands in real time and perform a series of operations on the image. The specific operation method is similar to human touch screen technology, but it is undoubtedly countless times more advanced.

He pulled the image slightly, and the influence of the earth suddenly magnified rapidly, and a huge physical sphere seemed to appear in the control cabin, which looked lifelike and dusty, if not looked closely, it was just like the real thing.

Moreover, this image is still the current real-time state of the earth, and the outer part of the earth is shrouded in a layer of white-gray light fog, and the situation of the earth cannot be seen at all.

"Remove the polluted atmosphere!" Luo Yuan frowned slightly.

As soon as the words fell, the earth suddenly revealed its original appearance, and Luo Yuan nodded in a certain position: "Just go there?" ”

"The coordinates have been entered, apply to open the dome ......"

"Application Approved......

"Anti-gravity engine start-up ......"

Virtual Location Imagery Affects Startup ......

"The ship is about to break away from the mother ship, please get ready."

As the dome above the head opened like petals, the small spaceship began to rise slowly, breaking away from the mother ship, and in just one minute, the main engine port suddenly erupted a brilliant and dazzling streamer, and the entire spaceship suddenly flew slowly towards the earth.

It was getting faster and faster, and in the blink of an eye, the mother ship was left behind, getting smaller and smaller.

Luo Yuan sat on the suspension chair, curiously looking at the image of the virtual location on the three-dimensional screen, but after watching it for a while, he lost interest, he picked up the comparison data of Boxing language and Chinese characters in his hand, and looked at it carefully.

Due to the popularity of personal biological terminals, in fact, the Boxing people rarely use paper, and are generally only used for precious historical archives and backup materials.

It has a very long storage time, has the ability to prevent waterproof, fireproof and corrosion, even if it is thrown in nature, it can not rot for hundreds of years, and it is precisely because it is difficult to corrode naturally, the use of this paper has strict restrictions, and every time it is obtained, it must be clearly registered for use and destination, of course, this kind of regulation can not control Luo Yuan.

He sat in the captain's seat, and after just a few minutes of watching, the small ship had already begun to enter the Earth's atmosphere.
