However, that was a special military train or freight train. The train Rhine was taking now was a very ordinary passenger train, so it not only had a luxurious first-class cabin, but also a luxury business class, ordinary cabin, economy cabin, cheap standing cabin, and a freight cabin specially for transporting goods. The conical carriage he was in was the most luxurious first-class cabin in the train.
The layout of the luxury cabin is completely different from that of the carriage above. It is not distributed in the form of seats, but in the form of private rooms.
The outermost compartments are the most expensive, because passengers can not only see the tunnel through the windows, but also replace the floor with a transparent glass floor. Passengers in the inner compartments can also see, but they only see the images captured by the camera.
Since the Earth Center Train uses unmanned driving technology, there is no cockpit. Rhine's compartment is located at the front of the train, at the top of the cone.
In fact, there are no private rooms on the bottom floor at the top of the cone, because there is only one room on the entire floor, a luxurious circular room with a diameter of about 20 meters. This is the private room belonging to the royal family of the high elves.
The decoration in the room is extremely luxurious, and is no less luxurious than the luxurious suites Rhine saw in the Royal Resort of the High Elves. But you have to know that this is just a means of transportation.
But soon, he found that these decorations were just models fixed in place and had no practical function. But that's right, it's not a sightseeing train, the whole journey only takes a few minutes, not even enough time to take a nap, so there's no need for so many fancy things.
Just as Rhine was wondering what the meaning of the sealing suit was, a sweet girl's voice came from the radio in the room.
"To protect your life, please do not take off your airtight suit at will, and fasten your seat belts under the guidance of the staff. The train will be injected with deep-sea fluid in 5 minutes..."
While listening to the radio, Rhine followed the instructions and asked Alisha to sit on a sofa similar to a child safety seat. After making sure that Alisha's seat belts were fastened, he started to do it for himself.
He found that although he could no longer move after fastening his seat belt, he could control the position and angle of the sofa through the remote control lever on the armrest, a bit like driving an electric wheelchair. So he drove the sofa to the huge transparent floor-to-ceiling window.
Five minutes later, a pool of transparent liquid that looked like transparent glue or lubricant appeared on the ground. As time went on, the liquid quickly filled the entire room.
At this moment, his sealed suit seemed to sense the changes in the external environment, and the display screen on the helmet began to show prompts of program running.
"Begin testing deep sea fluid density"
Start to remove air from the human body
"Begin to adjust the human body's magnetic field"
……
Although he didn't know the principle, after a series of operations, Rhine found that he didn't feel suffocated at all without breathing. He guessed that it was probably because the airtight suit gave his skin the ability to breathe in deep sea fluid.
Generally speaking, the train will only start when all the carriages are filled with deep-sea fluid, a process that takes from half an hour to an hour.
But because the train was carrying only two passengers this time, Rhine and Alisha, the train started after the rooms on their floor were filled with deep-sea liquid.
"The train will depart in 10 seconds, please be ready."
When the countdown ended, the pipeline shut down the magnetic levitation device used to fix the train, and the train suddenly fell. However, the speed was not very fast at the beginning, it was just a free fall.
The train uses magnetic restraint technology, so there is no need to worry about the train hitting the tunnel wall during the fall. It will only fall within the magnetic channel.
Rhine adjusted the angle of his seat so that he was sitting at a 90-degree angle to the pipe, and then replaced the floor with a transparent glass floor so that his face could see the falling process.
He watched himself flying through one blue halo after another. At first, there was one every few seconds, but later it became one every second, and then several every second. This showed that his falling speed was gradually increasing.
Theoretically, without the influence of air resistance, the falling speed of an object will become faster and faster until it reaches a constant value.
The fall continues.
Rhine looked down and saw a series of concentric circles of blue light coming towards him. He kept passing through the largest circle, and new small circles kept appearing at the center of the circle and quickly expanded. Soon, he could no longer tell how fast he was falling, and all he could see was a blue "time and space" tunnel.
Perhaps it was because of the deep-sea fluid, or perhaps it was because of the anti-gravity system inside the train, Rhine did not feel any sense of weightlessness caused by the fall.
At this time, Rhine noticed that a line of red words appeared in the liquid crystal display area in the upper right corner of the transparent mask that looked like a fish tank: "You have now reached a depth of 1000 kilometers underground, and your speed is 14 kilometers per second. You have passed through the discontinuity of the earth's veins and entered the mantle from the crust."
While falling, Rhine discovered that the tunnel was not completely straight, but had a certain degree of curvature.
After reading the official introduction about the geocentric tunnel, I realized that a straight planetary tunnel can only be realized on the axis running through the two poles of the planet, that is, the tunnel between the North Pole of the Penicsia world and the South Pole on the Dark Continent.
But this tunnel is only between the continents of the northeastern and southwestern hemispheres. The two points are at a certain angle to the earth's axis, and the rotation of the planet must be taken into account.
Although you can't feel it in the tunnel, that's because the distance is too long and the change is too small. But if you look at the official tunnel model, you will find that the tunnel is a double helix structure. The reason for the double helix is that there are two tunnels, one going out and one returning, but they merge together at the starting point and the end point, so it feels like there is only one tunnel.
"You have now reached a depth of 3000 kilometers underground, with a speed of 24 kilometers per second. You have entered the viscous material area of the mantle and are entering the electromagnetic acceleration tunnel area. For your safety, please stop all actions and hold on to the handrails."
Less than 3 seconds after the prompt ended, Rhine found that the blue space-time tunnel in front of him turned into a green space-time tunnel, and there were repeated arrows. Although it is a bit abstract, if I use a simple example, it is like the acceleration channel in QQ Speed?
"You have now reached a depth of 15000 kilometers underground, with a speed of 51 kilometers per second, and have entered the rigid material zone of the mantle."
"You have now reached a depth of 28000 kilometers underground, with a speed of 105 kilometers per second. You are passing through the mantle discontinuity and have entered the core of the star."
"The core of a planet is located at the innermost part of the planet. It has a radius of about 34700 kilometers and is mainly composed of iron and nickel. It has a high density. The average density of the core material is about 17776 tons per cubic centimeter. Except for strong interaction materials, no other material can exist under such a strong pressure."
"The general temperature of the core layer of a star is between 4000 and 6800 degrees. Under high temperature and overpressure, the iron, nickel, silicon and other materials in the core are molten or nearly liquid. When the core flows slowly, the planet's magnetic field is generated."
Rhine discovered that during the falling process, the display not only shows the current position and status, but also explains some little knowledge about the planets and the earth's core tunnels. This shows how popular the culture was during the era of the High Elves.
"You have now reached a depth of 41000 kilometers underground, with a speed of 185 kilometers per second. You are in the middle of the liquid core."
"You have now reached a depth of 54000 kilometers underground, with a speed of 235 kilometers per second, and are approaching the solid core. Our planet is larger than we imagined. If there were no tunnel to the center of the earth, it would take several days to travel from Penichesia to the other side of the planet."
"You have now reached a depth of 68000 kilometers underground, with a speed of 285 kilometers per second, and are approaching the center of the earth."
"You have entered the center of the earth and are about to reach the destination of this trip. The train is slowing down and is expected to arrive at the center of the earth in 1 minute. Thank you for riding."
“??? We’re here so soon?”
Rhine felt like he had only been sitting up for a short time. He had been watching the data changes on the display, but in the blink of an eye he was told that he had reached the center of the earth.
(ps: To repay everyone, I will open a silver treasure chest between 6pm and 10pm on Friday night. Mainly because I have no money, I can only give a silver treasure chest as a token of my appreciation, and it can also be regarded as a celebration of my achievement of 100 million words. It feels like time has passed so quickly. When I published the book, it was February 2th, and now it is almost August. 10 million in half a year, this speed is not too slow, right? If you want to maintain the book, it is best to subscribe from time to time, because the follow-up reading rate is really low. I feel that the more I write, the less passionate I am.)
Chapter 303: The Incredible City at the Center of the Earth
"The train is slowing down. Please fasten your seat belts and do not perform any operations."
"30 seconds, 29 seconds, 28 seconds to the center of the earth..."
"Dear passengers, we have arrived at the Geocentric City Station. Thank you for riding this time. The train will need to descend to the designated parking space. To ensure your safety, please do not unfasten your seat belt before the "seat belt signal light" goes out. Please do not leave your seat before the deep-sea fluid is discharged from the cabin. Please take all your carry-on luggage with you when you get off the train. Please go to the baggage claim area in the waiting hall to collect your checked luggage."
Just as the train broadcast was still playing polite words like thank you for riding, a buzzing sound was heard outside the train.
Afterwards, the deep sea fluid in the room was being drained rapidly.
Just as Rhine was about to unbuckle his seat belt, he heard a broadcast that concerned him very much.
"If there are passengers who are continuing to Penicia, please get off and wait. During this period, your luggage will be automatically transferred to the train to Penicia, but please take your valuables and confidential items with you when you get off the train. We will return to the Academic City Station after staying in the Earth's Center City for about 24 hours. If there are passengers who want to transfer, please ask the ground staff for the train to Penicia after getting off the train, and exchange or receive the ticket with your ID card. Please don't walk far while waiting and listen to the broadcast to board the train. Thank you again for choosing to travel on "Earth's Center No. 3". I hope we will have the opportunity to serve you again. I wish you a safe journey. Thank you!"
"What's the matter, Your Majesty?"
Alisha asked, looking at Rhine who suddenly froze.
Because she didn't understand High Elf language, she didn't know what the broadcast was about.
"Alisha, if you have the chance, would you be interested in visiting where I live?" Rhine asked.
"Where His Majesty lives? Okay." Alisha agreed without thinking.
After the deep-sea fluid was drained, Rhine unbuckled the seat belt around his body.
When he was moving his hands and feet, he found that although his whole body was soaked in liquid just now, there was no water stain on his body now, and he didn't even feel wet. It seemed that the material of the sealing suit had good waterproof and hydrophobic properties.
"The bridge has been connected. Passengers please leave in an orderly manner."
"Come on, let's see what hell looks like."
Because the cone-shaped carriages are luxury first-class cabins, the corridors connected by the corridors are different from those connected by the ordinary carriages. They have their own corridors, namely the VIP corridors. After all, the passengers who can ride in the cone-shaped carriages are either members of the royal family or other important figures, and it is impossible for them to leave with ordinary people.
In the sci-fi corridor, Rhine was walking and suddenly stopped, staring at the map on the wall.
Before this, he had always thought that there was only the Great Library of the Void in the center of the earth, but when he saw the introduction to the city in the center of the earth hanging on the wall, he realized that he was wrong.
The entire city in the center of the earth is divided into three cities and 24 districts like the Academy City, among which the Void Great Library is located in District 17 of the inner city.
The so-called three cities refer to the outer city, inner city and imperial city.
In the outer city, tourists can move freely without any permission; in the inner city, there are many important facilities, such as the Great Library of the Void, various scientific research bases, government agencies, etc., so only people with relevant permissions can enter; as for the last imperial city, as the name suggests, only relevant workers working in the imperial city or royal members can enter.
Don't think that the High Elves Era was a harmonious society with no class differences. The High Elves' royal family had the supreme status in that era.
Ultimately, this harmonious society was created by the high elves. The harmony here means that the high elves treat all races under their rule equally, whether they are humans, orcs, or other races. Everyone has equal status and no one is nobler than anyone else.
It’s just that the high elves are not a race that likes extravagance and debauchery, nor are they as arrogant as the elves of later generations, so they don’t give people a condescending feeling.
It can be said that every high elf is a born scholar. Compared with eating, drinking and having fun, they prefer to do scientific research, pursue truth and explore the unknown. Even the royal family is no exception.
"Your Majesty, where are we going next?" Although Alisha couldn't understand the words on it, she knew it was a map.
"Go here." Rhine said, pointing to the place in District 8 of the outer city.
The reason why we didn't go to the Great Void Library in Area 17 was because Area 8 was an energy supply station, which contained a device for charging the elves in the Divine Realm.
In this unfamiliar place, Rhine decided to wake up Laplace first.
Not only because he needed someone to act as a guide for him, but also because he needed Laplace, the high elf encyclopedia, to educate him on science.
Before leaving the station, Rhine had some questions that needed to be clarified, but he searched the entire station but could not find the staff mentioned in the broadcast, and he didn't even see a single intelligent robot. The entire station was silent, and there was no third person except the two of them.
Fortunately, there are self-service machines in the station so he can check the train schedule information himself.
But unfortunately, except for one train returning to Academic Capital Station 24 hours later, all other trains have been suspended.
It seems that his plan to take the opportunity to return to the Penicheia continent has failed.
After leaving the station, Rhine followed the signs to the driverless taxi parking lot.
The method of taking the taxi is very simple. Just put your ID card on the door. I don’t know if the taxi will still be able to move after tens of thousands of years.
With the mentality of giving it a try, Rhine found the most beautiful and handsome taxi in the entire parking lot.
As a result, as soon as he put the ID card representing his royal identity into the corresponding groove, the car swallowed his card.
You have to know that in the secret realm of the high elves, the ID card is the universal pass. If you don't have the ID card, it is no exaggeration to say that you can't move forward.
Just as he was about to dismantle the car, the door opened from the side. After making sure that the card could still be taken out, Rhine asked Alisha to get in the car.
After setting the destination on the LCD screen in the car, Rhine took out a few bottles of wine that looked very expensive from the car refrigerator. After checking with his identification skills that the wines were still drinkable, he poured a glass for himself and Alisha.
Anyway, the Royal Card is free for consumption in 99% of the places, so why not use it?
I have been busy traveling all this time, and I am still busy traveling now, but I can now relax a little.
"Alisha, don't you have anything you want to ask me along the way?"
Rhine sat half paralyzed on the sofa, holding an expensive glass of red wine in his left hand and holding Alisha's shoulders with his right hand.
"What should I ask?" Alisha didn't drink, but obediently lay on Rhine's chest.
"Like where is this place and what is my purpose for coming here." Rhine said as he took another sip of red wine.
"Did Your Majesty plan to come here from the beginning?"
She asked! Alisha finally asked her first question.
"That's not the case. I came to the maze mainly to see if there is anything I can use. Who knows there is such a huge secret realm of high elves hidden under the maze."
"What is the secret realm of the high elves?"
Alisha continued to ask questions based on Rhine's answer.
"Speaking of the secret realm of the high elves, we have to start from the era of the high elves. Let me tell you, tens of thousands of years ago, there was an unprecedentedly prosperous civilization in the world..."
Just as Rhine was talking endlessly to Alysha about the knowledge related to the Age of High Elves, the driverless taxi slowly drove out of the underground garage.
When Rhine was speaking with great interest, he suddenly stopped and his ears twitched unconsciously.
"Am I drunk? Why do I hear the sound of waves?"
"Your Majesty, I heard it too." Alisha sat up from Rhine's arms, so as not to affect his next actions.
When the hovercraft drove out of the underground tunnel, Rhine's eyes were not used to the dazzling sunlight for a while because he had been in the dark environment for a long time, so he had to squint. When he opened his eyes again...
"Alicia, kiss me. Let me see if I'm drunk."
Although she didn't know how this worked, Alisha still kissed Rhine on the face.
Feeling the fresh fragrance from his nose and the remaining warmth on his face, Rhine was sure that he was not drunk.
"This is the sea, right?" Rhine asked Alisha beside him.
"Yes, Your Majesty."
The scene before Rhine's eyes was an endless golden ocean. He could be sure that this sea water was real water and not a lava sea.
The undulating coastline offers beautiful golden sands to the surging waves. The beach is covered with various shellfish because there are no tourists all year round. The collision of waves makes a strange and loud sound. After opening the car window, you can feel the salty and humid sea breeze blowing on your face.
There is a real ocean in the center of the earth, 78000 kilometers away from the surface! This is even more fantastic than a fantasy novel!
Do you know why no one except gods, not even demigods, can enter the center of the earth?
Because of the unimaginable atmospheric pressure.
At the center of the Earth, you would be bearing the weight of the entire planet.
