In the transmission center of the transmission base, a mechanical female voice sounds: "The pipes from the earth's crust and the kingdom of the earth have been connected, please enter the transmission chamber A1005 within 15 minutes, sit down and fasten your seat belt.

An Ran and Li Huasheng walked into the tube-shaped, pill-shaped transmission compartment, which was equipped with 20 seats facing the wall of the transmission compartment and forming a circle in the center, they sat down and fastened their seat belts, and after waiting for a while, the remaining 18 seats were full, everyone was talking quietly, and one of them, a young man with a childish face, seemed to be riding the transmission compartment for the first time, and looked around with a little curiosity.

The radio is going on again.."Please sit down, now count down to 3, 2, 1, and it's officially launched." The transmission chamber descended to the center of the earth, and the indicator light pointed to the current passing through the earth's crust, and they looked out of the small circular window, only to see the pitch black, and in the limited light to see the layers of rock walls, the indicator pointed to the transmission chamber descending 40 kilometers into the mantle layer, and saw a fiery red tumbling magma from the small window.

The young man was pleasantly surprised, "We walked through the lava and it didn't feel hot at all, it was amazing!

The bald uncle who was traveling with him touched the little mustache on his lips and said, "The transmission pipe on this layer is made of extremely heat-resistant tungsten carbide (WC), and the outer layer of the transmission compartment is made of synthetic diamond, which can withstand the high temperature of 3,000 degrees Celsius.

The general temperature of the Earth's mantle is around 1,500 degrees Celsius. So it's safe to stay in the transport warehouse.

The young man blushed a little and said embarrassedly, "Hello everyone, my name is Sammi. I was born in a surface base in the Northern Hemisphere, where my parents were both on duty, and it was the first time I had returned to Inner Earth in a warehouse.

I have an older sister who went to the center of the earth to study in the city of Suo, and she stayed there to work as a doctor in the hospital after graduation, and she asked her parents to arrange for me to go to the high school in Suoru City, and after we settled down, my parents will leave their jobs after the completion of their service in the surface base in December next year and return to Suoru City to reunite with us.

Thank you, bald uncle, for your explanation, you are so knowledgeable!" The bald uncle nodded and said, "Hello Mori, nice to meet you.

My name is Charlie, I can't tell you that you are so young and not yet in high school? Don't be nervous, we'll be in the Inner World soon.

The city of Soviet Russia is a large city with a population of more than 10 million, and I used to spend a lot of time there, and the people there are very respectful and public, and it is a good place.

Come on!" The indicator light points to the transmission chamber descending 80 kilometers into the magnetosphere, hence the name, which is composed of iron, nickel and other metals melting into fluid, in the flow of iron, nickel and other metals into a large amount of electric current, creating the earth's magnetic field.

Charlie, the bald man, added: "This section of the transmission duct is made of reinforced ceramic insulators, so it allows the transmission compartment to pass through the magnetic layer smoothly.

Patted the young man and said, "It's safe." When the indicator pointed to the transmission compartment descending 100 kilometers and reaching the gravity layer, An Ran and Li Huasheng suddenly felt the familiar feeling of gravitylessness.

Yes, this layer is the most magical region, because above this gravitational layer, people are affected by gravity and stand on the surface of the earth; Underneath this layer of gravity is the centrifugal force of the earth's rotation, and man is affected by the centrifugal force with his head towards the center of the earth and his feet on the ground inside the earth.

Because the gravity of the gravity cancels out the centrifugal force inside the earth, the gravity disappears when passing through the gravitational layer, and people enter a weightless state.

The female voice is on again, "Please sit down, hold the armrests of your chair with both hands, and in 15 seconds your seat will be upside down.

An Ran, in the sense of gravity, saw the seats easily flip up and down, and now their heads were facing the center of the earth and their feet were facing the surface.

The material that makes up the gravity layer is a surreal material, made of technology from outer space, so that Charlie, the well-informed bald beard, can't easily explain it, he grins and touches the bald head and says, "The structure of this layer can only be asked online by the artificial intelligence teacher!

After about 30 minutes, the light pointed to the transmission chamber descending 140 kilometers to the protective layer of life, and they felt gravity again, but there was no obvious discomfort, as if they were living on the surface, and they did not feel that gravity had strengthened or decreased.

This layer of life protection is made of reinforced ceramics and fiber-reinforced plastics, strong, insulating and insulating, a thin layer, about 15 kilometers thick, which they look out of the window and quickly pass through this white smooth layer.

"Please note that you will be arriving at the next stop in the work area where you need to live, and those who want to get off the train in the work area should be prepared.

Charlie, the bald man, stroked the young man's hair and said, "I'm getting out of the car, please take care, there will be a date later."

The young man Mori smiled, "Uncle Charlie left me a light brain ID, I will talk to you when I have time, and I will have a long experience."

Charlie, the bald man, said, "Good!" The two exchanged optical brain IDs, and the transmission compartment ascended to the work area required for life from the bottom up, referred to as the work area, and the bald little bearded Charlie and the 6 people in the company waved their hands and left.

"The next stop is the human living area of the terminal station, please get ready to get off!" The radio sounded again. Li Huasheng said a little reluctantly, "Brother, we can't see each other for a while, after I go home, I won't go to work at the moon back base, and before you return to the moon back base after your vacation, you will use your light brain to chat with me, I live in Huaxia City in the northern hemisphere, and I will take the bullet train home later."

An Ran's eyes were red, and he said nonchalantly, "When you work together at the Moon Back Base, thank you for taking care of you for more than 3 years.

After I return to American City in the Northern Hemisphere, I will be back to the moon base in 3 months. I wish you a happy family and a happy journey in the ecosystem.

Li Huasheng left the transmission warehouse, said goodbye to Enron, took his luggage, and went to the platform where the bullet train was taken.

The bullet train is in a vacuum tube with the principle of electromagnetic levitation to push the transport capsule forward at high speed, fully autonomous, its track is straight, the transport capsule is as narrow and slender as a bullet, and can only accommodate 30 people.

Because the platform on which the bullet train operates is located above the working area and below the living area, there are no obstacles in this mezzanine, and the track of the bullet train needs to be rerouted, and it can move forward like an airplane without avoiding obstacles.

Hop on the train at the Arctic Bullet Railway Station and it only takes 3 hours to cross the other side of the world to the Antarctic Bullet Railway Station.

Li Huasheng's bullet train to Huaxia City in the northern hemisphere takes only 1 hour. "Finally home!

Li Huasheng walked briskly on the way home.
