Three days later...

"This is the transfer company between the two realms, the express passage to the upper realm, please open the security door with your ID card, and sit in your position and don't move at will."

On a platform similar to a train station, a silver-white hovering train is parked, and in front of it is a circular track like a Ferris wheel.

The lower world and the upper world are divided into two planets, and they are attracted to each other, just like the relationship between the Earth and the Moon.

The only difference is that there are no people on the moon, while the upper world is inhabited, and the civilization is more developed than the lower world, and it is there that the center of civilization.

"Sir, do you need coffee, we have handmade coffee here, it's definitely a royal treat!"

Wang Xu and Jasmine sat in the carriage, looking at the scenery outside through the glass, until a call came from their ears.

Looking down, the technological differences between the two worlds have been undoubtedly revealed at this moment.

Standing in front of the two of them was not a human, but a crawler service robot pulling a cargo box, selling products like a real flight attendant, and even speaking in the same tone as a human.

"I want a cup of coffee!"

After Wang Xu finished saying his request, he turned his head to look at Jasmine and asked, "What are you drinking?" ”

"Anything." Jasmine seemed to have lost her soul, there was no focus in her eyes, and she subconsciously spoke.

The robot moved its tracks, tilted its head to look at Jasmine, and said: "Sir, your friend doesn't look very good, according to the thirteenth law of robots, as a service robot on the train, I have the right to scan the passengers on the train without authorization, so as to notify the medical robot if necessary." ”

Zizi!!

Two red lasers, shot out of the robot's gaze, scanned Jasmine's body from top to bottom.

Jasmine was startled by the red light, and in her unfocused gaze, she regained a little regain her spirit.

Wang Xu saw that she was struggling, patted Jasmine's hand comfortingly, and whispered, "Normal physical examination, don't worry." ”

The robot's scanning was quick, and the red light was over with a sweep from above.

After the scan, the round crawler robot retracted the red light and replied in a low voice: "Madam, your blood sugar is low and your brain is highly active, I have preliminarily determined that you are in a state of extreme excitement, do you need me to call the medical robot for you?" ”

"Oh no, no, no, I'm fine!" Jasmine hurriedly excused herself and explained to Wang Xu in a low voice: "I'm fine, it's just that happiness came too suddenly, and when I thought that I was about to go to the upper world, I felt unbelievable, as if everything in front of me was just a dream." ”

"It's not a dream, I promised your uncle to bring you up, I'm a man who keeps his promises." Wang Xu smiled disappreciatively and said to the robot: "A cup of coffee, a cup of juice." ”

"Thank you for your patronage, eighty-three dollars!" The robot has a sensing zone on its chest with a paid 83$ symbol flashing on it.

Wang Xu took out a red card from the pocket of his jacket and swiped it in the sensing area.

In an instant, a green light lit up on the sensing area, and Wang Xu's avatar flashed in the video window on the robot's belly, and the three words in the check flashed on it.

"Didi, identity confirmed, 83 yuan has been deducted..."

After the robot deducted the fee, two silver metal tubes stretched out from the cargo box it was pulling, and began to pour drinks into the cups of Wang Xu and the others.

Wang Xu sniffed his nose gently, the strong aroma of the coffee couldn't be stopped, and the smell made the mouth dry.

When I took a sip, it was slightly hot, but the taste was unprecedentedly good, far better than any kind of coffee Wang Xu had ever drunk.

"It's so good, it's hard to imagine that such coffee was actually drunk on the train!" Wang Xu nodded with satisfaction and asked rhetorically, "What kind of coffee is this?" ”

"This is a mellow coffee produced by Fair, the taste buds are stimulated by different taste substances, and the information is transmitted from the taste nerve to the taste center of the brain, and people have a sense of taste and distinguish the taste of food. If you have a need, it is recommended that you buy the Shuffle 2200 model kitchen robot produced by the God of Food, and now there is a 60% discount on the purchase! ”

Wang Xu was still listening carefully at first, and when he listened to it, he felt that something was wrong, it seemed to be an advertisement.

Looking at a serious advertising service robot, Wang Xu took another sip of coffee and asked, "How much advertising money did Fell Company give you?" ”

"Sorry sir, your question is a trade secret and I have no authority to give any answer." The robot walked away under Wang Xu's disgusted gaze, and soon fooled others again.

Wang Xu shook his head slightly, looked at Jasmine who was drinking juice, and whispered: "For the upper world, we are hillbillies who have entered the city, and they will definitely do their best to cheat us out of our money." These people's routines are too deep, and even the words of robots can't be trusted, so we have to be careful. ”

Jasmine opened her mouth and said nothing in the end, just nodded silently.

Seeing her appearance, Wang Xu put down the coffee in his hand and asked, "What do you want to say?" ”

"It's so expensive that my mother works in a factory and only earns 32 yuan a month, which is not enough for a glass of juice here. I think if she knew, she would be distressed to death, and I couldn't believe it was true. Jasmine held the straw in her mouth and whispered with a dreamy face: "I also have a feeling of dreaming, as if the whole worldview has collapsed." ”

Wang Xu has some empathy for Jasmine's statement.

In the sixties and seventies, China was not like this, workers worked hard for a year, let alone in the developed countries of Europe and the United States, and even on Hong Kong Island, which is across the river, it was just a day's salary for others.

The gap between the lower world and the upper world is even greater, just like the China in the sixties and seventies, directly compared with the modern China.

The former has a salary of dozens of dollars a month, and the latter has a salary of tens of thousands of dollars a month.

"The lower world is a prison, and the upper world is the world of flowers, and there is no comparison between the two at present, and it is difficult to say in the future." Wang Xu raised the coffee, lightly touched it with the juice of jasmine, and said, "Cheers!" ”

Listening to soothing music and drinking crazy coffee, the transit train finally started slowly.

The upper world is parallel to the lower world, which also means that the train will cross the starry sky to the planet on the other side.

Wang Xu thought it would be as exciting as a roller coaster at first, but it turned out that he was wrong, and it was very wrong.

The full name of this transit train across the two planets is called the anti-gravity transit levitation train.

It has orbits, but no matter how it changes, gravity is always under control.

If you don't look out when you sit on it, you won't even notice it moving, even if you get motion sickness, you won't get dizzy when you sit on it, because it always maintains its own angle and center of gravity.

When you look out from the car, you can see the vast universe.

You will find yourself so close to the universe that it is as if you can travel to the universe by breaking the glass on the train.

However, this idea can never be realized.

The glass here is super tempered glass, even if a meteorite hits it, it's fine, and from here you can see how advanced the technology is in the upper world.
