So, should you eat it up before hibernation, or wake up from hibernation and enjoy the good times?

How to achieve the highest level of satisfaction while reducing the risk of problems such as spoilage is a difficult mathematical problem.

Extremely bored, Zhang Yuan has been constructing a "satisfaction function" and a "deterioration risk function" in his mind, trying to obtain a higher degree of satisfaction at the cost of two kilograms of beef jerky.

Half a quarter of an hour later, there was a soft "bang", and the elevator they were carrying had reached the surface, and the outside temperature displayed on the instrument was minus 170 degrees Celsius.

"Mr. Zhang, I can only send you here."

"Maybe we will never see each other in the future, can you... give me a hug?" The little girl in charge of receiving Zhang Yuan hesitated for a while, then whispered in his ear. Nothing happened in the past few days, and she still felt it was a pity.

Zhang Yuan froze for a moment, opened his hands, and hugged this girl whom he had just known for five days.

Enduring the pain, he still gave her some of the beef jerky in his hand.

"Thank you for your care these days, this little gift is for you."

The girl jumped up happily: "Ah, you are such a good person! I haven't eaten beef jerky from the earth for a long time... Sigh, everything here is very expensive..."

From her surprised eyes, it can be known that this thing is definitely a famous "luxury" on Europa.

It's no wonder that the organizers regard them as small gifts.

Although Europa has begun to breed some livestock, in order to maintain the health of the ecosystem, the output must not be high.

"Just a little beef jerky. Nothing."

Zhang Yuan felt sad, the astronauts might have to face such a bleak tomorrow.

Perhaps... more bleak.

"Bon Voyage!"

Nodding slightly, Zhang Yuan turned around and took the train to leave. From a distance, he could still see the girl waving her hands inside the glass window.

The space elevator is hundreds of kilometers away.

"goodbye!"

Along the way, you can see all kinds of busy construction site scenes.

The flame of nuclear fusion has been ignited on this planet, and the next development is only a matter of time.

With efforts from generation to generation, this place will become another home of mankind.

maybe……

Compared with the earth, Europa actually has many defects. The surface here is full of ice, and there is no shortage of water resources, but this planet is abnormally lacking in metal elements, rare earths, and organic matter.

The current mineral mining companies can only develop certain large meteorite mines that fall on the surface. However, the reserves of these meteorite mines are all quite limited, and there will be no more after mining.

Jupiter also has another relatively large satellite, Io, which is even more difficult to mine.

The size of Io is similar to that of Europa. It is a terrestrial planet, but many super volcanic activities and super earthquakes occur frequently, making it an extremely dangerous planet.

No one would invest in an unstable place. Maybe in a few years, a super earthquake would wipe out all the investment.

From this perspective, there is still considerable room for improvement in the level of human interstellar development.

If there is enough power to quell volcanoes and earthquakes, there are still many places in the solar system that can be inhabited...

"Brother Zhao, I have noticed that some people's bodies have degenerated seriously due to improper maintenance, and their muscle lines are different from normal people." Zhang Yuan asked quietly when returning to the Earth Era by space elevator.

"This kind of drastic physical change may cause some irreparable damage. Even if you finally return to Earth, it will be difficult to recover, right?"

This question has been lingering in my heart for a long time, and I don't have time to ask it. It seems to be relieved to ask it at this time.

Under low gravity conditions, the pressure on the intervertebral disc caused by body weight between the vertebrae disappears, the compression of the intervertebral disc is released, and people become taller.

Normally, as long as the damage is not serious, the astronauts will return to normal height after returning to Earth.

But the low-gravity environment can have a cascade of effects on gene expression. For some people who are severely degraded, they may no longer be able to adapt to the earth's environment.

"Have you noticed it too..." Zhao Qingfeng thought for a while, then whispered, "Do you think they are from the Xia Kingdom?"

"It looks like it shouldn't be. I can't understand what they are saying."

"Will it be American, or Lan Guo?"

Zhang Yuan shook his head, "Probably not."

"Then who do you think they are and where they come from..."

Maybe... some small countries?

After pondering for a while, I suddenly realized.

Behind all the glamor and beauty, there are countless unknown nights.

The salaries of normal technicians here are too high, starting with an annual salary of one million. And most people's contracts are only three years, and they will eventually return to Earth.

Three years is actually too little compared to the decades-long development cycle. Frequent turnover of personnel is definitely not good for the entire development project.

That being the case, for the entire civilization and some capitalists, there must be some more "money-saving" and "economical" ways.

Even though the current automation industry is quite developed, the role of humans cannot be easily replaced in a complex environment.

Zhang Yuan asked quietly again: "Have these people settled here?"

"Yeah, from the beginning, decades ago."

"Why would anyone want to do that?"

Brother Zhao smiled and sighed: "What you think is good or bad, whether you like it or not, is only a relative term. Why do some people want to live in poor mountains and bad waters? Why do some people live on high loess slopes? Why do some people still live in rural areas instead of cities?"

"Compared to the hard times in the past, what's so bad about settling here? As long as you sell your labor, at least you won't have to worry about starving to death, and you can still live happily. There are more promising places on earth..."

Zhang Yuan was silent, and found himself asking a stupid question. He asked again: "So, can they reproduce?"

Brother Zhao looked around for a while, and then said, "It is said that it can."

After a pause, he added, "With the current medical level, it's still possible. It's just a little risky, and the chance of pregnancy is not high."

There was a deathly silence in the air. Zhang Yuan originally wanted to ask, under such drastic environmental changes, would the evolution from generation to generation lead to reproductive isolation and the formation of different races?

But after much deliberation, he swallowed those words again.

Physiological screening will take at least tens of thousands of years, right? Asking him to think about this issue is indeed a bit beyond his control.
