The last human in the universe

Chapter 161 Let's Start
This is a huge planet far away from the star and with extremely low temperature.According to the existing theory of stellar system evolution, if the raw material of the interstellar cloud cluster that formed the Rakai 9352 galaxy was sufficient, the planet surrounded by the Yuanhang spacecraft at this moment should have formed a gaseous giant planet.

If that's the case, it should become the core of the gas giant planet at this moment.

But unfortunately, the evolution of planets and stars has not yet reached the end, and the raw materials have been exhausted.As a result, it became a rocky planet up to 2.1 times the mass of the Earth, and Rakai 9352 formed a red dwarf star.

Because of the distance from Lakai 9352 and the low temperature of this star, the temperature on planet 3 is extremely low, not even enough to vaporize hydrogen.As a result, it has no atmosphere.

——To be more precise, there is no atmosphere in the macroscopic sense.

However, it is precisely because it has no atmosphere that Zhao Changxing and other civilization leaders set their first stop when entering this star system.

At this moment, its true appearance appeared on the big screen, in front of Zhao Changxing and others.

It was a dark and cold world.On this world, the mountains are undulating, the basins are sunken, and there are endless frozen objects stretching on its desolate and barren land.Occasionally, dark red dots can still be seen from above the planet, but they often disappear quickly.

That's a volcano on this planet.

Yes, it also has more frequent geological activities.The high-temperature lava from the depths of the ground erupted thinly, not only ejecting a large amount of high-temperature gas, but also melting the solid hydrogen, solid oxygen, dry ice and other substances frozen on the surface.

If the volcanic eruption is too violent and the energy released is too high, this cold planet will temporarily have a relatively thin, but at least macroscopic, atmosphere.But unfortunately, this atmosphere is not long-lasting.Under its own extremely low temperature, and under the violent stellar wind, it tends to lose it very quickly.

After releasing some satellites and organizing a group of scientists to conduct a systematic and comprehensive understanding of planet No. 3, Zhao Changxing finally issued an order that all the waking people have been waiting for for a long time.

"let's start."

"start!"

"start!"

Accompanied by the cheers of tens of thousands of people, the first batch of hundreds of engineers and skilled workers, carrying a large amount of automated mechanical equipment and building materials, left the Yuanhang spacecraft on two space shuttles and landed on this spaceship. On the ground of the planet.

Dai Yunfei is one of them.

The place where the space shuttle landed was a small plain next to a huge canyon, or flat ground.

It is very small, only a few square kilometers at most, but it is completely enough to build the first factory after human civilization reaches this star system and this planet.

The canyon next to it is hundreds of meters deep.According to preliminary calculations, there are at least hundreds of billions of tons of water ice resources in it.

If this planet is as warm as the earth, then this place should be a huge lake.

Wearing a spacesuit, standing on the surface of this planet, feeling the gravity about 1.2 times that of the earth, Dai Yunfei let out a long breath.

He knew that at this moment, about a thousand kilometers above him, there were millions of compatriots waiting for him.

"let's start."

Saying something to himself secretly in his heart, Dai Yunfei started busy with his companions.

According to the plan, the first thing people need to do after they are finally parked in orbit around planet No. [-] is not to wake up the hibernating people, nor to build various grain factories, nor to build a "roller" base, but, Immediately build an electromagnetic railgun base on the planet that is rich in water resources, and launch a large amount of the most valuable and most urgently needed water ice to the Yuanhang spacecraft.

Yes, the resource most urgently needed by the Yuanhang spacecraft at this moment is water.Because it is so important and can play too many roles, it can create almost everything people need.

First of all, large pieces of water ice at extremely low temperatures can absorb the excess heat in the Yuanhang spacecraft and relieve people from the extreme heat.And this, for subsequent needs, is also a process of dissolving water ice into water.

After this, the water is electrolyzed, the oxygen is used for respiration, and the hydrogen is used for fusion to generate energy.

At this moment, the Yuanhang spacecraft has switched from the positive-antimatter annihilation power supply mode to the nuclear fusion power supply mode.As long as there is enough hydrogen, nuclear fusion power plants can generate a steady stream of energy.

In comparison, the annihilation of matter and antimatter is more similar to battery power supply.The nuclear fusion energy supply is similar to being connected to the power supply.

This means that people can be completely freed from the state of shortage of resources and energy.

At this moment, this small piece of flat land has turned into a busy construction site.Many machines are busy in it, and countless robots are shuttling among them. Dai Yunfei and others are wearing space suits with mechanical exoskeleton functions, and they are doing some work that robots cannot do.

The land leveling work was completed in less than a day.After this was the foundation construction, which only took one day.After that, it is the construction of the factory building, equipment installation and commissioning, and the fusion power plant that is next to it also quickly appeared on the ground...

All this work was completed in less than half a month.After that, the first standard resource box that could hold 100 tons of water ice was launched into space and captured by the Yuanvoy spacecraft.

Compared with planet No. 3, which is huge, with a mass of 2.1 times that of the Earth and a surface gravity of 1.2 times that of the Earth, the construction of a space elevator is a project that is infinitely more complicated than that of Sedna.In comparison, although the efficiency of the electromagnetic railgun is lower, it is more concise, simpler and more practical.

At the same time, this is also the most important reason why civilization leaders such as Zhao Changxing came to this planet in the first place.

Because this planet has no atmosphere, the electromagnetic railgun can launch resources from the surface into space without any scruples.And if there is an atmosphere, the electromagnetic railgun cannot be used at all.

Because the dense atmosphere will slow down the standard resource box violently.At the same time, the violent friction with atmospheric gases can place almost unacceptable demands on material properties.

At that time, the space elevator will not be built in a short time, and the electromagnetic rail gun will not be able to be used. People will have to rely on inefficient space shuttle ships to carry materials one by one.

The 100 tons of water ice in the first standard resource box were quickly placed on the internal conveyor belt by the people who had been waiting here for a long time.At the end of the track, the nuclear fusion electric field inside a spaceship has been waiting for a long time.

It was first sent to the electrolysis workshop, and the hydrogen was sent to the material bin.Following Zhao Changxing's order, the initial energy from the outside world activated the nuclear fusion equipment that was already in place.

A huge amount of energy is continuously produced from this fusion power plant.

What greeted them was the cheers of everyone present.

At this moment, on the canyon on planet No. 1000, many intelligent excavators are shuttling back and forth, sending large chunks of water ice to the tracks and passing them into the factory building, like ants running around.Inside the plant, with the first launch, people adjusted the parameters slightly, and then started the second and third launches, and the quality of the launches was also improving rapidly, and finally stabilized to about [-] tons of water per launch. ice level.

Every day, such launches will be carried out 720 times, and 72 tons of water ice will be sent into the Yuanhang spacecraft.

With the sufficient supply of water ice, one fusion power plant after another began to operate, and thus, in the Yuanhang spacecraft, one system after another, which was shut down for the purpose of saving energy and resources, was activated again.

The first thing to be activated is the temperature control facility.

Driven by sufficient electric energy, the liquid used to transport heat began to surge again in the outer shell of the Yuanhang spacecraft with a total area of ​​thousands of square kilometers and a total length of tens of millions of kilometers. Excessive heat is continuously transferred from the interior of the spacecraft to the outer shell, and then dissipated through radiation.

A long-lost coolness appeared around everyone.

"It's finally cool..."

Dai Yunfei, who had already returned to the Yuanhang spacecraft, sighed in a low voice.

The next thing to be activated is the air filtration system.As a result, the ubiquitous stench, sour, and sweaty smells that filled the air began to slowly decrease, and finally disappeared.The fresh air that only existed in memory appeared around people again.

After that, the remaining two huge "drums" were also activated.This means that people's living area has tripled in this instant.As a result, a large number of people who do not have any fixed residences have regained their spacious homes at this moment.

Then, water restrictions were lifted.

An hour before the restriction order officially came into effect, Dai Yunfei had already returned to the assigned temporary residence, waiting by the bathtub.

At this moment, Dai Yunfei was similar to almost every other famous companion, with a body full of mud, exuding a pungent sour and foul smell, and no hair on his head.

Severe itching comes from all over the body at all times, but almost everyone is used to this feeling, and they don't even bother to scratch it.Occasionally, the itching is so severe that I can't help scratching it. There will be a white mark on the skin, and some black mud will appear in the nails.

In the past, this situation seemed tolerable.But now that the water was coming soon, he felt that he couldn't bear it for a moment.

While waiting anxiously like scratching one's ears and cheeks, the time to lift the water restriction finally arrived.

He turned on the faucet, and the clean and clear water gushed out.

"Finally I can take a bath, finally, finally..."

He murmured, almost tears in his eyes.
