As a member of the scientific expedition team, Zhang Yuan was one of the first people to land on Europa.

He cautiously stepped down the space elevator and strolled over Europa's ice cap. In the dark sky, only a few lights flickered. These permafrost ices have never melted since they appeared, and they are at least a billion years old.

If you look up, you can see Jupiter.

It's really overwhelming, it's about 23.5 times the size of the Earth when it saw the Moon, and it's visible to the naked eye that Jupiter's surface is lined with wood-like lines one after another.

Sometimes you can also witness the famous, dark red red spots, like a huge eye, quietly watching them.

If it is some people who are afraid of ghost stories, they may be scared to death at the sight of this real blood moon.

Zhang Yuan took a few photos with interest.

This side of the tide lock was chosen as a base because the place is less likely to be hit by a meteorite.

Jupiter, the big guy, has cleaned up countless meteorites for the inner planets of the solar system. With Jupiter as a shield, the Earth is much less likely to be hit by meteorites, providing a more favorable environment for the formation of life.

But Europa was not so lucky, living here, the probability of suffering a meteorite hit was greatly increased.

The entire interior of the base is also equipped with the most powerful helium-3 nuclear bomb to defend against possible meteorites. No way, who made Jupiter the most important reservoir of nuclear fuel?

"Friends from afar, welcome to Europa Industrial Park. The very edge of human space deployment. A middle-aged man in a space suit stood at the gate of the base and greeted everyone with a smile.

Immediately afterward, he and the captain shook hands again.

Academician Ding turned around and said to Zhang Yuan: "Let's go, this alien base may be similar to our future deployment...... You should take a good look at it. ”

"I have a few old friends here who want to visit, do you want to go with me, or do you want to go freely?"

Zhang Yuan thought for a while, "I also have an elder who wants to visit." Let's move freely for now! ”

"See you in the afternoon."

The first thing Zhang Yuan did when he walked into the Europa base was that Meimei had a barbecue meal!

The aroma of barbecue made his saliva water, and the sense of anticipation of saliva secretion was comparable to doing a math problem!

Even if it doesn't taste as good as a meal on earth, it's not synthetic meat anyway.

Europa's base is heaven compared to a spaceship!

"Not bad, really good! The turbulence problem is solved by you! The middle-aged man sitting across from him, a former colleague of his father, gave a thumbs up and compliments.

"Uncle Yuan, it's just luck. A method of numerical simulation, in fact, does not completely solve the ......," Zhang Yuan smiled embarrassedly.

"Luck? It's about strength! You think I don't know how to do it? There are many applications of turbulence, from astronomy to geography, if you look at Jupiter, that big red spot, isn't it formed by turbulence? By the way, what time does the meeting start? ”

"About one o'clock in the afternoon." Zhang Yuan replied.

"Then you can take a little rest."

The group had been invited to Europa to attend an academic conference on industry.

In this base, there are many existing achievements, which are the crystallization of human wisdom and are worthy of reference.

The large buildings inside the ice sheet are actually very exquisite. Various structures such as heat dissipation, support, and sewage discharge need to be planned as a whole. In particular, the heat emitted should not exceed the capacity of the entire ice sheet, otherwise the ice will melt too much, which may cause serious accidents such as landslides and earthquakes.

Europa, as a relatively successful planet of immigrants, is definitely good for field trips and learning a little more new things.

"Uncle Yuan, when are you going to go back to Earth?" Zhang Yuan patted his stomach with satisfaction and asked again.

"In three months, it will be three years, and I will never come to this ghost place again, there is no way to live video, and I haven't seen my son and daughter for a long time. The muscles also began to atrophy, and if I didn't go back, I would have a green grassland on my head. ”

"How can it be......" Zhang Yuan hurriedly snorted.

Europa produces the most important resource of a civilization – energy. So this is the equivalent of the previous Middle East, and the salary must be top-notch.

An ordinary worker has a work cycle, which is about three years.

Even the lowest-level positions can earn millions.

But because you are far away from the center of civilization, although you have money, you can't enjoy it, let alone take care of your family, so you will inevitably take some risks...... All kinds of bullshit, hard work to make money back, only to find out that the stories of cuckolds are simply countless.

"If there's anything else you want to bring back to Earth, I can be a courier for you." Uncle Yuan said with a smile.

"Hmm......" Zhang Yuan thought for a moment, "Is there a postcard?" I'll just send some postcards back. ”

"Okay, there are just a few more, I'll give them all to you."

After thinking about it for a while, Zhang Yuan wrote a few letters to Wang Lili and Xu Yunjing, Professor Wang Zhong, sister-in-law's family and Han Ziyue.

It's very brief, and he talks about his recent experiences and feelings.

When he wrote Han Ziyue's letter, Zhang Yuan was stunned and didn't know what to write.

"What, it's a girl?"

"Ah, a pretty cute girl. I don't know how it's now. ”

"That's ......" Uncle Yuan smiled, as if he understood.

What to write?

Zhang Yuan had an idea and drew a portrait of himself on a postcard, with a planet floating in the sky, that is, Jupiter.

His level of drawing was not very good, and he had only briefly studied with the painter Erwin. The whole portrait looks crooked and cracked, much uglier than himself.

However, because of its ugliness, it looks inexplicably funny.

Sign your name on the bottom.

[Zhang Yuan, 2265.8.31]

I don't have the opportunity to be with you all the way, and I don't have an excuse to talk to you all night, and I don't have the opportunity to tell you about my current life, so I can only send a postcard to tell you that I'm fine, and it's better to miss seeing each other.

Cherish each other.

Zhang Yuan sighed slightly in his heart.

In the end, he also kept one for himself.

After some consideration, he wrote: "Today, we have arrived at Europa, the outermost industrial base of mankind, where the mothership will carry out its last resource replenishment. Europa is not as good as Earth, but it is much more down-to-earth than a spaceship, after all, it is a planet. 】

[Next, we will go to the distant starry sky, I don't know, when we will reach another planet. 】

[The night is long, and I don't know the road ahead. I hope that in the future, we will be able to remember this beautiful and warm day. 】

【2265.8.31】

It's written, but it's inexplicably heavy.

Zhang Yuan raised his head and said, "I'll keep this one for myself, and the rest, after you return to Earth, just help me put it in the mailbox." ”

"Well, that's a little thing. So outward! Uncle Yuan put away the stack of postcards and nodded solemnly.

"Thank you! I'll go first. ”
