Zhang Yuan came to the train station non-stop.

A message was displayed on the mobile phone: "[Dahua Transport] Dear passenger Zhang Yuan, your ticket has been successfully paid at 10:03. July 14, 2264 train number G888 second class, Donghua (10:30) - Xisha (11:45), ticket number 781234......"

The time was almost up, Zhang Yuan boarded the train and found his seat and sat down.

A soft electronic sound sounded in the carriage: "This train is going to Xisha, the duration is one hour and fifteen minutes......"

The gray-black sea-crossing bridge is like a long dragon lying on the sea. Modern carbon nanotube materials can handle even a 36,000-kilometer space elevator, not to mention a small sea-crossing bridge on the ground.

These bridges can easily withstand a Category 16 typhoon.

Traditional means of transportation, airplanes, are about to be eliminated. There is no big problem with fuel, and hydrogen fuel can be used instead of traditional fossil fuels, but the carrying capacity and operating costs of the aircraft cannot be compared with that of maglev trains.

In addition, the speed of the maglev train is close to that of the airplane, the fare is cheap, and it is very comfortable, and there is no tinnitus problem caused by air pressure, so the plane is slowly losing its competitiveness and is on the verge of elimination.

An hour later, a few vague shadows finally appeared on the blue sea level, which were fusion nuclear power plants.

The fusion nuclear power plant at sea is 300 meters high, and because of the huge amount of heat dissipation, all the white fog around it is evapotranspiration water vapor. This distilled water is collected and supplied to the city.

Xisha Aviation City, located in the southernmost sea area of the Xia Kingdom, had territorial disputes with surrounding small countries hundreds of years ago. Accidents involving the detention of fishing boats and misfires often occur.

However, the times are developing, the society is progressing, and with the rise of the Xia Kingdom, these bullshit disputes have all become floating clouds.

"Controlled nuclear fusion is a good thing. How much can 3 cents per kilowatt-hour of electricity reduce the cost of industrial production? Other countries still play with eggs? ”

Fusion power plants have a not-so-glamorous feature: the larger the unit, the more stable it is, and the lower the cost of generating electricity. Coupled with the limitations of human technology, there is no way to miniaturize nuclear fusion devices, so every nuclear fusion power station is like a small mountain.

Nuclear fusion and the space economy have made Xia the first country to eat crabs, and they have made a lot of money, so it is not impossible to leak a little soup for the surrounding brothers to drink. Territorial disputes have long been gone. Those who have attained the Tao have much help, and those who have lost the Tao have little help, and interests are the closest bond between countries.

The train sped past the nuclear power plant.

"Look, look! It's a space elevator! ”

"Where, where?"

"That's it...... Hair as thin as a strand. ”

Squinting your eyes, you can faintly see a slender pillar towering over the sea of clouds, like a kite string.

Under the sunlight, there is a bright sense of unreality.

High.

It's too high......

Many people who saw the space elevator for the first time couldn't help but lie on the glass window and take pictures.

The legendary "Tower of Babylon", a miracle in history, on the planet, there are 17 in total. In the next 30 years, it is expected to increase to more than 30 seats.

Xisha Aviation City has the first space elevator "Tengyun" in human history. Its geographical location is about 300 kilometers from the equator. Keeping the space elevator at a slight slope maximizes the use of the Earth's rotational power, allowing the elevator to have a greater carrying capacity.

After nearly 100 years of development, Xisha has become an international metropolis.

"Won't it collapse?"

"How is that possible? The principle is different, the space elevator mainly relies on tension, not pressure. Do you understand the pull of the rope? ”

"Will the terrorists hit this tower?" Those who have good deeds open their minds and think wildly.

“…… It is said that attacking the space elevator is equivalent to starting a nuclear war and will be subject to reciprocal retaliation. Xisha City is relatively strict security, there are troops stationed nearby, and planes are not allowed to pass by ......"

"Brother, are you already in Xisha City? I just saw your circle of friends dynamics~~~"

At this time, my sister-in-law's daughter Ye Qingqing called, "Are you going to space?" I really want to go on a space tour, but my parents want me to work and study to make money, 30,000 yuan a trip, I earn the Year of the Monkey and the month of the horse......"

She was almost dying of envy.

"Space tourism, it's not wonderful at all, I'm serious." Zhang Yuan said with a smile, "Let's work slowly first, under the age of 18, you can't get a tourist visa at all." ”

It's one thing to get a visa, it's another thing to get a tourist quota.

The space elevator has a limited number of daily cargo deliveries, so there are not many places for tours. Not to mention spending money, maybe you have to rely on the relationship. This thing of human sophistication will not be completely eliminated in any era.

As we talked, the speed of the train slowly stopped.

"Dear passengers, the terminal station - Xisha has arrived, please bring your carry-on luggage and prepare to get off the train......"

When the train arrives, tourists excitedly look at the space elevator not far away, no matter where they are, as long as they look up, they can always see the thick pillar.

This kind of great power from science and technology and industry can fully stimulate the national pride of the Xia people. Almost all space elevators in the world have Xia Guoren's technology and shares in them.

After a lot of contact, Zhang Yuan didn't feel anything, but he just rented an unmanned motorboat by himself.

"Wow!"

The motorboat sailed fast in Xisha City, splashing with water.

Xisha City is like summer all year round, but the temperature in July is less than 30 degrees, which is much more comfortable than Donghua City anyway.

The city is mostly an artificial island, connected by bridges between the islands, with plenty of waterways and sometimes tropical fish.

There was once a leader who patted his head and wanted to fill in these waterways and replace them with land routes to improve transportation efficiency, but the result was unanimously opposed by the broad masses of the people, and the reason was ...... They find motorboats more fun and can attract tourism.

Facts have proved that the masses of the people are really right once. The omnipotent air rail solves the traffic problem, and the water traffic really promotes tourism.

"Drip ...... The service fee: 16 yuan. ”

Zhang Yuan stepped off the motorboat and came to his destination.

"I'm an astronaut on Earth Age, can I report now?"

The service staff of the Deep Space Planning Bureau swiped his ID card, smiled slightly, and said, "Mr. Zhang Yuan, you still have 19 days left on vacation, and you came too early. It's not your turn to lift off the batch yet. ”

"It's not...... I just want to ask, is there a place where I can stay? ”

The service staff smiled and said, "I'm sorry, if you arrive 3 days early, we will help you arrange accommodation." But now, it seems that there is no such arrangement. ”

"You might want to go to the university next door and see if there are any empty dormitories. I'll help you get an astronaut certificate. ”

Zhang Yuan frowned, he came too early and was disgusted. This kind of thing is normal, and the service staff just follow the rules.

"Okay then, thank you."

"You're welcome!"

There are many aviation universities stationed here, some of which are international schools, and they recruit students from all over the world. However, because of the summer vacation, most of the students are on vacation, and the university is empty.

Soon, Zhang Yuan saw the four gilded characters of "Xisha University". Since he looked more like a student, he was not hindered from entering the school.

Zhang Yuan asked several people in a row before he arrived at the bottom of an office building, [Deep Space Foundation (Xisha University Branch)]

"Hello, I would like to meet Wang Zhong, Professor Wang."

"Do you have an appointment?"

“…… There are no reservations. ”

"I'm sorry, I didn't make an appointment, Professor Wang is very busy."

As a last resort, Zhang Yuan could only take out the big killer, the astronaut certificate, and his father's ID card.

Although this kind of thing of relying on the father is very embarrassing.

"I'm Zhang Qiming's son, so I said...... Can I visit Professor Wang Zhong? ”
