Three days passed in a hurry.

Except for the toilet, everyone is confined to their seats. It's like going to jail, and it's a hard thing to do.

Gravitational force is decreasing little by little, and when the centrifugal force is completely equal to gravity, people will experience the sensation of total weightlessness.

The freshness of the tourists has long since passed, replaced by an inexplicable restlessness and irritability. It's been three days, and no matter how beautiful the scenery is, it's become commonplace, and the excitement at the beginning has turned into boredom.

Weightlessness, which looks funny and funny, is actually a terrible thing.

First of all, the blood pressure in the head will rise, and the legs will begin to swell, and there is a figurative medical term called "pig-headed bird's leg syndrome". A medical term is called the "Charlie Brown effect".

Second, as the brain loses its grip on gravity and floats within the skull, it can lead to blurred vision, which is collectively known as vision impairment and intracranial compression syndrome.

Even if medical technology is developed, these diseases will not disappear, so the elderly and underage children are not allowed to go to space.

In this case, the tourists became unusually silent and spoke softly.

Boys can only pretend to be bold, and girls become real ladies.

"Mr. Zhang, do you have a feeling of panic? I didn't feel too comfortable. ”

"No, it's good to get used to it. You can take a little bit of low-potency nitric oxide and other medications. ”

"I've eaten it, and I still feel bad."

Zhang Yuan said with a smile: "In addition to physiological factors, there are also psychological factors, which are a bit similar to wilderness phobia. The main thing is that this place is empty, and when you get back to the ground, it will be fine again. ”

The girl, who had just known her for three days, stuck out her tongue and her face was not very good.

Actually, it's not just her, it's almost everyone.

Perhaps she recalled, it was in the boundless universe. Man and the universe are separated by only a thin layer of glass.

Outside was utter nothingness, nothing but deadly radiation.

The slightest mistake can leave an entire batch of people dead without a place to bury.

Or perhaps, they suddenly turned around and looked down at the earth from an altitude of more than 30,000 kilometers, and after entering a broader line of sight, they would find that the earth was really too small and too small, just a small stone floating quietly in the solar system.

Almost all human beings thrive and live on this small stone.

Humanity has created countless stories here.

Including the four ancient civilizations, the eight wonders, the four world wars, countless love and hatred......

But the earth is too small, and all history, culture, religion, and wars are just small stories on small stones.

Humans and bacteria, there's really not much difference.

All the intrigues, flies and dogs, have become bacteria devouring each other.

The head of the coalition government has become a bacterial leader.

The richest man in the world, equivalent to the largest individual in bacteria.

And then what?

Which bacteria died, which bacteria gained a mate, and which bacteria was the glittering mass admirer...... Even if she completely conquers the earth, what does this mother, who is herself very doting on her children, say?

The world out there is so big, so big!

This wonderful contrast made the pride that they had generated from their conquest of nature a few days ago completely burned to ashes.

A few hours later, in silence, the world-famous "Tenglong" space city arrived.

"It's so small, why is it so small......"

People's first reaction turned out to be this space city, so small.

The tour guide introduced: "It's not small, it's a kilometer in diameter!" After all, it was an old device from a hundred years ago, and there was no space elevator at the beginning, so how difficult it was to rely on the propulsion of rockets to build this space city. ”

The gravity-free experimental area, the plant cultivation area, and the ring-shaped living area are all familiar to the public.

Because of its early age and outdated facilities, this space city has gradually become a sightseeing and tourism place, as well as an interstellar port for cargo delivery, and there is not much scientific research equipment.

Small, coupled with being deserted, means there is little sense of security.

Even if they managed to reach their destination, they didn't excite the tourists. Everyone just looked at it symbolically, but the tour guide kept introducing.

"It was in this space city that the Portuguese grass was born, and it is called 'the gift of space to mankind.'"

"If you live in a gravity-free zone for a long time, you will grow taller. It is very possible to stay in space for a while, and grow five centimeters tall......"

No matter how much emotions are mobilized, people still don't react much.

There are a lot of people taking pictures, and there is already a ground network in this space city.

They "click" to take photos and upload them to the circle of friends, so that relatives and friends envy it......

Anyway, you have to pretend to enjoy it. After spending money, you can't say it's not fun, right?

The vast majority of people are completely frightened after going to space once, and they don't dare to come up a second time.

Humans have evolved on Earth for millions of years and have a certain certainty, even if a self-righteous grasp, of where they live.

Abandon the gentle harbor and go to the kind of lonely and fearful life, not everyone wants to.

Zhang Yuan sighed, he has experienced this kind of thing a lot, and he is used to it. Anyway, there are so many people who sign up for space tourism that there is no need for repeat customers.

He turned his head and said with a smile, "Ms. Li, we are about to follow the team to the moon, so let's say goodbye here." ”

The girl, who had been in the same carriage for three days, asked, "Mr. Zhang, I have one last question for you. ”

Zhang Yuan said: "I was thinking, you might be a journalist? From your every move, it seems to have this characteristic. ”

The girl raised her eyebrows and said with a smile, "You found out!" But I don't mean to interview, but I want to know privately why you and your companions have left the solar system and traveled so far. ”

Zhang Yuan thought for a moment and replied, "My answer to your question is, I don't know. ”

"Don't know?" The girl looked puzzled.

"yes, we don't know. I don't know about the world outside the solar system, so I want to see it. Do you see the earth under your feet? Do you think that our home planet is very small, just a very ordinary sapphire? ”

"yes, it's small." The girl sighed, "When I came to space, my whole state of mind seemed to be a little different, as if there was a feeling of detachment from the world...... Although I still feel scared. I still want to thank so many space workers for their silent dedication. I finally understand why their salaries are so high. ”

Zhang Yuan continued: "I don't know how vast the starry sky is, we want to know. ”

"We don't know what will become of the earth in 3,000 years, we want to know."

"I don't know, it's our motivation."

"We must know, and we will know."

There is always a small group of people who are willing to summon up the courage to bounce high from the small rock, lift the tip of their heart, stand on tiptoe, stretch out their fingers, and touch the deadly and endless starry sky.

Even at the cost of life.

The woman was silent for a while, then smiled and said, "Your answer is really philosophical. I'll write it down, can I post it to my friends? ”

"It's better to ...... Don't do it! Zhang Yuan felt that he really couldn't afford to lose that face.

Several people laughed.
