Emerging from the airport, the two boarded a free vacuum speeding train to the North Pole of Ceres.

After boarding the train, Su Ruyu's mood improved slightly, and she said to Lu An with rare appreciation: "This is probably the only place on this planet where the anti-smuggling team does not charge." ”

However, inside and outside the words, the style of the anti-smuggling team desperately reaching out to grab money is still full of irony.

Speaking of which, speeding vacuum trains still charge a five-point ticket fee every time on the planet, which is used as the maintenance cost of such old and obsolete public transport facilities. And on Ceres, a planet entrenched by an anti-smuggling team desperately reaching out for money, there is a speeding vacuum train with free services, which really surprised Lu Anzhong.

Before, when he walked out of the hub airport, the evaluation of the anti-smuggling team was suddenly taken back by him, which gave him a slight look at this organization.

Perhaps, any organization that has existed since the early days of the galactic calendar has its own way of survival. As the saying goes, existence is reasonable, isn't it?

As the speeding vacuum train raced across Ceres, Su Ruyu yawned and fell asleep. It had only been less than an hour since she woke up from the dormant chamber and sat on the speeding vacuum train, so she was still in a state of sleepiness; She is not as interested in the scenery outside the car window as Lu An, nor is she like other passengers who can pass the boring time, so there is nothing else to do except sleep.

Lu An stared at the scenery speeding by outside the car window with great interest, but the speed of the train was thousands of kilometers per hour, so his eyes were sour after staring at the nearby scenery for a while, and he had to look at the scenery on the horizon in the distance.

When the super-speed vacuum train was first designed, it was actually designed to meet the transportation needs of outer space colonization, so it was specially designed to be a train that runs in a vacuum.

After the design is completed and the Pacific Ocean floor test in the first region of the Earth is successful, there is an ambition to complete the construction of a vacuum train network on the Moon and Mars.

It's a pity that the elated people were poured cold water on their heads.

Although the train overcame the resistance of air friction, it ran at an astonishing speed, and even ran at a speed of 5,000 kilometers per hour in the Pacific Ocean floor in the first zone of the earth, and it only took more than an hour to reach San Francisco from Shanghai-Hangzhou City. At that time, some people shouted the slogan "One Hour Planet", which means that when the global ocean floor is covered with a network of super-fast vacuum trains, it will be possible to reach any part of the earth in an hour.

At that time, the first century of the galactic calendar had not yet passed, and it was not until the first three centuries of the galactic calendar that mankind really realized the concept of "one hour earth", and this was completed due to the technological progress of human spaceships, not by the completion of the super-speed vacuum train network.

In the human world, speeding vacuum trains have become an antique that should have been eliminated a long time ago.

In the first century of the galaxy, people found a dilemma of "you can't have both fish and bear's paws" after the super-fast vacuum train was really put into the vacuum of nature.

On the earth, people racked their brains in order to obtain a vacuum environment, painstakingly pumped the train tunnel at the bottom of the Pacific Ocean into a vacuum, and then cheered for the speed of 5,000 kilometers per hour, because the vacuum in the universe is everywhere, and the most difficult passes have been crossed, and the next step is to bury themselves in building a network of trains like spider webs.

However, when it came to the universe where the vacuum was everywhere, people were dumbfounded.

Where vacuum is everywhere, what about gravity?

In order for humans to obtain the air they need to survive, they must need gravity to bind the escaping atmosphere, but when the atmosphere is bound, where does the vacuum environment be? Do you have to dig tunnels in the ground like a mole? Tunnels are dug on the earth for experimentation, so why build vacuum trains if you can't save the cost of tunnels?

In the end, before the end of the first century, the human world abandoned the construction plan of the super-speed vacuum train, leaving only the super-fast vacuum train at the bottom of the Pacific Ocean to grow old year after year.

However, Lu An didn't expect that after coming to Ceres today, he would see the real use of the speeding vacuum train.

Because this planet is not a human colony planet, it is completely the base camp of the anti-smuggling team, and these unlucky children have no intention of building this planet into a habitable planet, this planet does not have a complete atmosphere, so many places still retain an almost vacuum of primitive environments.

Looking at the horizon in the distance, Lu An gradually understood why the speeding vacuum train could be reborn here.

The dome buildings in the distance are clearly human settlements on this planet, there must be a completely closed and independent atmosphere, artificial gravity and other environments, and it is enough for the anti-smuggling team to guard the dome buildings with one one, so why bother to extend the atmosphere to the entire Ceres? Why bother building man-made gravity systems all over the world?

The anti-smuggling team entrenched in the asteroid belt may never have thought of expanding the dome of those dome buildings into the sky of Ceres. Therefore, the original environment in a large area is not transformed, and the super-speed vacuum train has gained a glimmer of life.

The independent and enclosed dome buildings may need a network connection such as a speeding vacuum train to connect these isolated islands one by one.

It is probably because of this that the top brass of the anti-smuggling squad did not go home, but provided this transportation service completely free of charge. Even, Lu An could see that the anti-smuggling team also maintained this means of transportation with all his heart.

For example, the clean and tidy carriage environment is much better than those old and dirty carriages on the earth, and the seat backrest that Lu An is sitting on still has a soft and comfortable feeling, unlike the carriage seats on the earth that make sleeping people very uncomfortable, and every time Lu An wakes up from the carriage, he has some back pain.

And, most importantly, there is also a network signal on this train, which is an interstellar quantum synchronization network that is common in the human world. Based on this alone, Lu An had to take a high look at the anti-smuggling team.

Otherwise, no matter how many brains are strapped to your wrists, you can only do the same as when you were on Earth, and the train in the Pacific Ocean Bottom Tunnel in Area 1 is a hypnotic journey.

Even if you have to find fault, it's that Ceres' train can't compare to the speed of Earth.

However, although the speed on the earth can reach two or three thousand kilometers per hour, it is not a commendable thing, just because of the geographical advantage.

The speeding vacuum train itself may be no problem with running at 5,000 kilometers per hour, after all, this speed is normal on Earth, but unfortunately it is not the same on Ceres.

Because on Ceres, a train with a speed of 5,000 kilometers per hour may not be called a train, but a flying train. The speed of 5,000 kilometers per hour is enough to break free from the original gravity of Ceres, reach the first cosmic speed and fly into space. On the planet Ceres, the escape speed of primitive gravity is only a pitiful 0.5 kilometers per second, which is only 1,800 kilometers per hour, compared with the second speed of 11 kilometers on the earth, it is really sad for the listeners and tears for the listeners.

Of course, Lu An's mood at this time was really a little sad, and he really wanted to cry without tears.

Although there was such a surprising service on this train now, he had no choice but to salivate and shake his head. Looking at his bare wrists, Lu An deeply realized what tragedy was.

The so-called tragedy is not that you have been suffering and cannot extricate yourself, but that you finally usher in happiness after suffering it, but that person can no longer distinguish what suffering is and what is happiness.

When there is no Internet, there is no brain; When there was no brain, the Internet did.

So, Lu An could only stare enviously at the wisdom of the passenger in front of him, and even stared at the person a little hairy, and after repeatedly confirming that he had no problem, he glared back at the inexplicable guy behind him, which Lu An was quite embarrassed. He was bored, so he had to learn from Su Ruyu's appearance, leaned on the seat and tilted his head and fell asleep.

……

"Wake up! Wake up! Hey, it's time to stop, wake up! ”

Lu An opened his right eye and looked through the gap that had opened.

Arrived at the station? I seem to be on a speeding vacuum train——, well, is it so soon? I don't seem to have slept for long this time, why did I get there? What time is it, and the public speeds in the city of San Francisco don't know what time they're starting to operate?

Hey, something doesn't seem right, why did I suddenly end up in the fourth district? Shouldn't I be at home with my sister? She's just recovered, so how can I run around?

Hiss——, shoulders are so heavy and a little sore......

Lu An closed his right eye, squinted his left eye and looked over his left shoulder, a clump of hair resting on his shoulder.

This woman ......

The tide of memories poured back, and Lu An suddenly came to his senses.

I wasn't on Earth! Or in the asteroid belt, on a speeding vacuum train on Ceres, not on the Pacific Ocean floor on Earth. Neither was he on his way to the city of San Francisco in the 4th arrondissement, but on his way to the north pole of Ceres.

It was so realistic just now, it turned out to be just a dream!

Lu Anzhong sighed silently, gently pushed a clump of hair on his shoulder, and said, "Hey, wake up, we're here." ”

Su Ruyu raised her head from the messy hair, and her crumbling bun was now all scattered and piled on the shoulders of the two people leaning together.

"Oh, it's here, it's here, it's here, let's go."

Su Ruyu reached out and wiped the saliva on her face, and replied with a blank face, and then she got up blankly, but sat back suddenly, holding her head and trembling.

"Got it again?"

Lu An comforted helplessly: "Before getting in the car just now, I said to help you re-tie it, you don't let it, you look at ......, good, good, good, you don't have to stare at me, I won't say it, I won't say it, it's okay?" ”

Lu An stretched out his hand to help her tie her hair, and at the same time endured the mental attack of this woman's teary eyes, and he was quite helpless in his heart.

By the time the two of them actually got off the train, it was already ten minutes later, and even the train staff who had come to remind them just now were already quite impatient, and their muttering attitude was not far from scolding.

Lu An, who was almost kicked off the train, and Su Ruyu, who was numb in her feet, got off the train, just like when she was at the airport, looked back at the train she was on, and scolded fiercely in her heart.

The previous high-level evaluation in his heart was taken back by him in his heart.
