The extremely low temperature of this planet often destroys the machinery on the surface. Even if human beings are at the peak of the third level civilization, all kinds of machinery still can't stand this ultra-low temperature, and the failure rate is quite high

Wang Haifeng looks at the time, puts on the power armour, and walks out of the industrial elevator.

"The current external pressure is 0.0000092 Standard atmospheres, and the temperature is minus 246 degrees Celsius."

"Be careful when you go out, and pay attention to the safety of your feet!"

With a click, the elevator reached the ground.

The gullies formed by snowflakes are actually frozen air. Because of the different condensation temperatures of the air, the frozen air here is stratified. Carbon dioxide is the first to condense, followed by methane and nitrogen. A small amount of solid oxygen can even be found here.

Solid oxygen is a light blue crystal, a bit like copper sulfate poured into water, solidification.

Sometimes you can find this kind of blue crystal on the roadside. The small one is as small as peanuts, and the big one is as big as a lake.

Boys and girls like to collect these beautiful blue crystals and carve them into jewelry, which is a kind of fun out of nothing - even if this kind of jewelry will soon vaporize and turn into gas at room temperature.

This big ice hockey has been fully tested, and there is no alien microorganism, so it is allowed to bring these small jewelry into the underground base.

"Senior engineer, Wang Haifeng, driver's license, a class." He drove a car to the space airport. Even though all the cars can be driverless, sometimes he still likes to drive.

After arriving at the destination, a small transport ship just fell from the sky to the ground, and the bright light seemed to shine an arc in the haze.

Then a few young people came up.

"Uncle Wang!"

"Here we are. Sit tight!"

The car galloped over the ice.

"The cracks in the surface of the ice shell were pulled out by the super gravity when they passed the neutron star. It will never heal. "

Wang Haifeng said to a group of young people in the car, the car suddenly leaped up, and "plop" flew over the crack.

These young people have just come here by transport spaceship and need to be given a good place to live.

A boy said ambitiously, "Uncle Wang, I'm going to trouble you these days. As the planet's geological features have changed, we need to find a relatively stable geographical location and build about 500 steering engines. "

Wang Haifeng said with a smile: "Hey, it's only 500 seats. Compared with the original 30000 seats, it's not difficult!"

"That's not true!"

The work of the planetary engine above the "js131" Planetary Fortress has almost been completed. The whole project center of gravity has been transferred to the third stage. More and more people have moved here to build large astronomical observation devices and a small number of planetary engines.

These planetary engines will be used to counteract the rotation of the planet.

A group of people talk and laugh, the atmosphere is warm.

Through the power a's own observation equipment, we can see that the planet js131, the Planetary Fortress, is located near the neutron star, about 2 astronomical units.

Two small neutron stars can't be seen simply, but they can be seen faintly enough, the colorful plasma flames on the surface of the Planetary Fortress.

"Our first planetary fortress It's beautiful. It's almost finished

"It's not really a Planetary Fortress. It's just the initial motivation. No weapons, no ecology

There are still more than 30 million people on the top. In the next 100 years, more minerals will be dug up to provide sufficient fuel reserves for planetary engines, and then people will be able to hand over everything to the fully automated system and leave

A boy discussed later: "there is a saying that we have made great progress in the past 1000 years. Long term practice has made us more mature at the industrial level, and our automation capability has been greatly improved. In the future, the development of such a war star can shorten the time by one third. And that escape happened a hundred years ago... "

"Is escape progress?"

"History can always bring some harvest..."

Wang Haifeng is too old to judge these young people's discussions. He went to the underground city and took off his power armour. Suddenly he shivered and breathed into his rough hand.

He thought of some relatives and friends who had left, including his two elder sisters and one elder brother. His dry old eyes were moist again They should have reached their destination and started a new life, right?

Wang Haifeng looked back and saw that some young people were looking for the most suitable engine construction site for the geographic information system.

The voice chirps and the discussion goes on and on, which makes it very energetic.

Although these young people look young, they are notA part of the population is selected from the virtual world.

The foundation of the new civilization school is far deeper than imagined. Among the hundreds of millions of people who have died, even if one thousandth of the outstanding talents are selected, there are hundreds of thousands

These selected extraordinary people, at that most dangerous time, have stabilized the basic situation of the society, so as not to let the whole plan really fail.

The reason why most of the young people are not incited is that they hold the voice of student associations and various student organizations.

There are still some small differences between society and school. At the beginning, the division of school and society did not take effect until thousands of years later.

Wang Haifeng set the relevant parameters in the computer and said, "you live in these rooms, 1109-1122. Two people in a room, the authority has been set, if there is a couple like you can tell me, adjust it

"A room for two would be nice."

"Thank you, Uncle Wang!"

Boys and girls immediately rushed to their homes, these days they can be exhausted, a good rest to be able to work well.

Only a team leader in blue overalls, still in a daze at the elevator leading to the outside world.

"What do you think will happen when the people who used to leave arrive at their destination?" Wang Haifeng pointed to the ceiling and asked the man surnamed Fang, the leader of the team and the most stable one.

"Nothing will happen It's just It may lead to social retreat. " The man, surnamed Fang, sat down, grabbed a handful of nuts and stuffed them into his mouth. He said, "if you want to make permanent progress, you have to pay a price. Otherwise, you can't even stay where you are and you will go back."

"We thank them and express our deep regret to those human beings, whose future is unlikely to be as beautiful as imagined. Where is the perfect society? "

Wang Haifeng can't deny it: "the future is chosen by themselves. How can it be bad?"

The man surnamed Fang said with a smile: "what they can choose What can they choose? People will change, and they will change very quickly. "

"Multi party system? I don't like multiparty system To pursue lofty goals and ideals, we must adhere to the one party system. Even if the one party system refuses to continue, what eternal progress does the ruling party pursue with the fluctuation of public opinion? "
