"Starlink's network manager must also be a southerner, he won't be comfortable if he doesn't see the rain, do you dare to come to some snow?"

Du Kai, director of the engineering department of the Gaoquan municipal government, was driving a three-wheeled tram and was patrolling the road at the edge of the shield, and he was quite unhappy to see the central area shrouded in a continuous drizzle. Recently, it has been raining a little frequently, and the water supply index is almost touching the top.

The urban water cycle project has not yet been completed, and the wastewater is directly discharged, as the former urban water pipe network engineer, this kind of thing is a crime at all, and he who sees this kind of thing happen but can't do anything is the same crime.

What's more, the water here is synthesized from hydrogen and oxygen in the primary plant, and the water is synthesized!

The primary material production factory, referred to as the primary material factory, after Du Kai arrived at Amstar, he was overwhelmed by the overwhelming new knowledge and new concepts, and this term is relatively easy to understand.

With a set of general production equipment, the production of iron, aluminum, titanium, copper, tin and other metals, as well as hydrogen, oxygen, helium, nitrogen and other gases, as the next level of processing raw materials, this set of production equipment is called the primary material production plant.

On the earth, this set of things is completely crooked, and each raw material has a set of sophisticated and complete production processes, which have been verified by the market for many years, and have the best solution in terms of efficiency and cost. But here, Starlink's subordinate Xingmen Infrastructure Company strives to use a set of equipment to handle the production of all raw materials.

They did a good job, smelting most of the commonly used metals through the intelligent ion furnace developed from the spacecraft's ion engine, and then doing the extraction of hydrogen, oxygen and other gases through various reduction modules. Even quartz sand can be directly produced from oxygen, quartz glass and monocrystalline silicon through a combination process.

Du Kai, as a technician who came to Amstar before immigrants, personally participated in the construction of Gaoquan City, and only then did he understand this idea of Xingmen Infrastructure.

The industrial system is as simple as possible, with as little equipment as possible, as short as possible processing links, and as simple as possible, so that the independent supply of raw materials, materials and components for interstellar colonies can be realized as soon as possible.

The industrial system is as adaptable as possible, whether it's on an asteroid, on Amm, or elsewhere, without spending much time designing and adapting.

As for efficiency, since the system is simple, the production efficiency will not be low. What is the cost, the machine is intelligently controlled, people do some maintenance and management work, and the rest is energy, catalysts and additives.

In terms of energy, Gaoquan City does not worry about electricity at all, it is all provided by the space reactor. Most of the space reactors came from spaceships during the Stargate War, and they still have years or even more than a dozen years of life, and the nuclear fusion power station is also a project in the expansion project of Gaoquan City.

Catalysts and additives are a problem, and Du Kai has also heard the people of Stargate Infrastructure complain that many of the things on it have to be transported from the earth. Xingmen Infrastructure is working hard to figure out how to produce its own catalyst additives, and how to improve the production process, directly relying on simple and crude ionization, magnetic field and even laser means to reduce the use of catalyst additives.

Therefore, in Amstar, not only Gaoquan City, but also the Starlink base and space center not far from Gaoquan City, the entire basic industrial system seems quite strange in the eyes of earthlings.

The raw materials are produced in the primary quality plant, and the processing plant uses these raw materials to produce various alloys and organic materials, and then directly manufactures high-volume finished products through external modules, such as power supply cables, water pipes, etc. As for the biomass such as water, salt, and mixed air, it is also directly encapsulated through an external module.

Then, there is no then. The manufacturing industry on top of this is basically covered by 3D printers and robots.

All kinds of components, from tools such as wrenches, pliers, and screwdrivers used by engineers to various parts of substations, are all printed on site by the 3D printers of the Engineering Department.

In addition to the battery, computer and cables, he operated a 3D printer to print out the other parts of the three-wheeled tram driven by Du Kai, and then completed the assembly with a remote robotic arm on the workbench, which took less than three hours in total.

As for the construction of large-scale projects, that is the stage for robots.

The construction process of the "buildings" of the various sizes of the "buildings" in Takaizumi City is quite interesting.

A deep pit was excavated on the site where the cabin was to be built, isolated and secured with baffles, and then a cage-like frame was installed. Then install the robotic arm, and the frame is the slide rail of the robotic arm. This part of the work, when there is no general-purpose anthropomorphic engineering robot, has to rely on people to do it, but after the adjustment is completed, people only have to watch.

The mechanical arm first builds the keel of the cabin layer, and then arranges the internal structure according to the design plan, and then closes the inner and outer layers of the keel, and then fills the inner and outer layers of the keel with gel materials to prevent various rays.

After the inner tube of the cabin is completed, the outer keel is built, this layer is to ensure the structural strength of the cabin, and the inner and outer keels will also be filled with aerogel.

From digging the pit, to removing the mechanical arm and frame, and backfilling the sand for use, the general residential cabin can be completed in three days at most. The various materials involved, whether it is a titanium alloy keel, an ordinary alloy steel plate, an organic material for the lining, or various components of the airtight compartment, do not need to be produced in advance, and are manufactured simultaneously during the construction process.

The building is still only pediatric, and the construction process of the urban shield makes Du Kai deeply shocked by the power of intelligence and robots.

It was half a year ago when he first came to Amstar, and Gaoquan City was just a circle drawn by a deep crater.

After the Star Alliance made a survey, it was confirmed that the wide valley of the plateau of Amm was the most suitable for building a settlement, and directly bombarded this circle of "foundations" with the railgun of the Scavenger.

Since then, a lot of things have happened, in addition to the liaison of the Star Alliance, Du Kai has also been in contact with the Blue Cross and the Star Gate Infrastructure, and I heard them say that the old spacecraft that was originally lowered as an energy station has also broken several ships, and almost had a nuclear pollution accident, because the cosmological constant here is a bit problematic, and the gravitational calculation is not accurate enough, so the most advanced artificial intelligence of the Star Federation has been adjusted.

When Du Kai arrived, the primary and processing plants had already been built, and the construction of the urban shield had just begun.

For Dukai, this is a big project, and it can't be done in three or five years on earth. But here, he saw the scalp-numbing pace of infrastructure.

There is no air or water, the temperature is as low as minus 250 degrees, and the skeleton of the shield adopts a three-stage structure. The lowest 100 meters are made of low-temperature alloy steel, the upper 100 meters are made of titanium alloy, and the rest is made of ultra-titanium materials that Du Kai does not know the details of, but only knows that it is lighter and tougher.

This valley is the least desertified area of Amms, with a sand layer only 30 meters thick and several kilometers of rock underneath. The city shield built by the Star Gate Infrastructure for Gaoquan City is 50 meters deep into the ground to ensure that it is embedded in the rock layer.

The outer shield, which is 3.5 kilometers in diameter and 600 meters high, was built in two months. A considerable part of the reason why it is so fast is related to the equipment of Stargate Infrastructure. In Du Kai's view, the engineering equipment of Stargate Infrastructure is slightly modified, and it is a weapon full of near-science fiction and has great power.

The digging robot of Stargate Infrastructure is a mechanical monster, similar to the giant sandworm in fantasy novels. The assembled body was free to move, and the head and body were covered with megalodon turbines, crawling all the way, throwing high pillars of sand, and it took only three days to connect the craters from the orbital guns into a 30-meter-wide sand channel, exposing the rock formations below.

After that, the excavation robot began to make a second turn, this time equipped with a high-power microwave transmitter on the head, which crushed the rock, and the pump-feed machine originally used to absorb sand ejected the crushed gravel again, which was relatively slow and took a week.

The excavation robot spent another four days making a third turn, laying the base of the skeleton, and then entering the erection of the skeleton. This part of the work requires people to cooperate with small engineering robots to build the keel of the first ten meters. The keel is a cross structure, the left and right ends are the connecting bases, and the upper and lower ends are the slide rails.

After the initial keel is built, people can rest again, and each keel is installed with a robotic arm that can move along the slide rail, and the robotic arm starts to build, weld or rivet a section of the upper section. These robot arms select components or tools from the material library prepared at the base as needed.

After the three-layer skeleton was closed in the center, the stargate infrastructure used a high-power laser to burn the landfilled sand and stone into glass, and firmly fixed the base.

After the skeleton is erected, the robotic arm continues to rely on the slide rail to lay the glass. For Amstar, which is dark in space, in fact, it is nothing to directly build opaque materials, but considering the mental health of residents, and the process of manufacturing quartz glass is simple, the materials are all over the ground, and with plexiglass, there is no problem in protection.

In the early two months, the outer protective shield was put up. The inner shield is still a gourd, and because it is smaller, the foundation does not have to be made so deep, and the progress is faster.

At the same time as the inner shield is erected, the internal "decoration" project is also being carried out simultaneously, of course, the so-called "decoration", even if it is only the air system, is a grand project on the earth.

At the edge of the inner shield, there is a circle of twelve columns about 200 meters high and more than 30 meters in diameter. These columns are not only the support frame for the shroud, but also the control system for the air.

The oxygen, nitrogen and other gases prepared by the factory outside the protective cover are transported to the air preparation station between the inner and outer protective covers, and the air preparation station is connected to the air circulation system and is intelligently controlled to form a new and old circulation of air. This air is assisted by the air supply and exhaust vents on these twelve pillars, plus the air inlets and outlets on the ground everywhere to form air circulation, which can be regarded as "artificial wind".

There is also a temperature and humidity regulation system for the air at the air supply outlets, which is intelligently adjusted by the municipal management GEI Mazu according to the set meteorological conditions.

The tricycle runs on the mirror-smooth obsidian floor, and Du Kai recalls the municipal miracles of Gaoquan City, and his heart is full of pride. He is a participant in every miracle, and he is still in charge of many small projects, and for a municipal engineer, what can compare to such a sense of achievement? Although Goquan City is small, it is a city of miracles.

But...... Even if it is a miracle, few normal people on the earth are willing to come here to live.

Thinking of this, Du Kai's heart couldn't help but be clouded with a layer of haze.

Yes, there are many miracles, and there are many defects. Not to mention being enclosed in this large glass cover, the ground is still full of sand, you can't see plants, you can't see fountains, you can't enjoy the fun of flying, the air you breathe is all made, there is no smell of fields, countryside and mountain forests, there is no hustle and bustle of the bustling city, and even the clothes are all close-fitting spacesuits.

No normal person would dare to come here and live with these stargate syndrome patients. In addition to the Blue Cross and Stargate Infrastructure, as well as Starlink's "new humans" who are not afraid of Stargate Syndrome.

His thoughts diverged, and Du Kai's heart became more depressed.

On PEI, colleagues have been chatting about the day, and Starlink Media's coming here to shoot a documentary is a hot topic. Du Kai thought of his relatives and friends who were far away on the earth and would never be able to see them in person in his life, and he felt even more sad.

In this life, will you really stay in this glass cover?

A woman's avatar suddenly popped up in the AR field of vision, it was his wife Zheng Ya, she smiled sweetly: "Get off work on time, don't run to the bar, I'll cook fish for you today." ”

Fish!?

Du Kai swallowed his saliva, but his mouth said, "What fish?" Don't be that kind of cloned fish, right? Not afraid of eating mutations? ”

Zheng Ya's little avatar glanced at him: "The space fish made by New Hope, I heard that the original fish eggs were frozen, sent over, and then hatched and raised, sturgeon." ”

Du Kai knows this, more than ten years ago, Norway developed the technology of freezing fish eggs, which can keep fish eggs at more than minus 170 degrees, which has nothing to do with cloning technology.

"Get a sturgeon and eat it twice, no, eat it three", Du Kai smacked his lips and said, then frowned: "Is it a benefit or a purchase?" ”

Zheng Ya said: "I still eat three things, there is no shortage of monosodium glutamate and salt, onions, ginger and garlic are all artificially cultivated, which is so expensive that it is dead, and soy sauce has to be saved." ”

She sighed again: "Of course it's a welfare, this is a gift from the first generation of successful breeding." You also know that even if it is a weed, it will have to be sold for iceberg snow lotus when it is brought from the earth, and when it is farmed on a large scale in the future, I am afraid that it will have to be bought at that time. ”

Zheng Ya's tone became a little heavy: "The city is expanding, and there will be more people in the future, so there will be no such good thing." Will the money we earn be enough in the future? It's just that we don't have anything to live by, but now we have children......"

Kid, by the way, I'm about to have a baby.

Although he can't see his parents and friends again, he at least has a wife, and his wife is pregnant with a child.

The rich warmth dispelled the previous gloom, and Du Kai smiled: "Wife, even if you don't have confidence in me, the director of the Engineering Department, you have some confidence in yourself." You are a teacher, and it is impossible for a school to do without a teacher. If the teachers can't get by, what future does this place have, what hope is there? ”

"Yo, you're not deceived by that kind of argument that artificial intelligence replaces teachers", Zheng Ya also laughed.

Of course, the wife is not afraid that she will not be able to live in the future, but she is afraid that she will not know what the future will be like, just like himself.

I was really hot-headed at the beginning......

Dukai thought that the Blue Cross would recruit space migrants in quarantine, preferably people with technical expertise, orphans, young parents, and couples who were already in a relationship.

He and his wife only met in Gaoquan City, they were both abandoned by society because of Stargate syndrome, isolated from their parents and friends, and almost desperate for the world, and immigration became their way to escape from the past.

Du Kai came first, Zheng Ya later, when he took the orphans to visit the city, Du Kai, the tour guide, called Zheng Ya. Judging from the speed of the earth, it was less than a month from acquaintance to marriage, and it was a complete flash marriage. But in Amstar, the city rises from the ground in two or three months, and people have no worries about status and wealth, and their interactions are purer and more need for mutual comfort, which is already slow.

Thinking about the sturgeon at dinner and the smiling face of his wife, Du Kai felt that the future was not so ethereal.

Next month, he will be transferred to the expansion project team in Gaoquan City, which is expected to accommodate tens of thousands of people, and the design plans will build the support columns into skyscrapers, and he will start to try to soil it, plant trees, build gardens, build lakes, and it should be a city that does not feel much different from the earth.

As he was walking, the checkpoint arrived, and he braked suddenly, and the electric car drifted out for a long time, almost hitting another electric car.

Du Kai reacted quickly, twisted his body, and pulled the car in the other direction, avoiding the car.

Without waiting for the car to stop, he jumped off, 170 centimeters and 180 pounds, but his movements were quite flexible, and after all, there was one-eighth less gravity than the earth.

"I'm sorry, I'm sorry! Fang Liai, are you alright? ”

The electric car also braked urgently, and the driver was a petite long-haired girl wearing a red and white Starlink uniform, with fair skin and delicate facial features, who looked very delicate and quiet. This is a person that everyone in Gaoquan City is familiar with and respects, surnamed Fang Mingping, only eighteen years old, representing the Star Alliance, responsible for the intermediary liaison between Amstar immigrants and the Blue Cross.

"Director Du, what kind of god are you going?"

Xiaoping waved her hand disappreciatively: "I've said it many times, just call me Xiaoping." ”

Du Kai scratched his head embarrassedly: "Ah, I'm sorry, thinking about miscellaneous things......"

"This is a lane, even if it's an electric car, you have to have the rules of motor vehicles on the planet in your heart!"

Xiaoping trained Du Kai seriously, and the latter listened obediently, the identity of the members of the Star Alliance was secondary, and Xiaoping led them out of the quarantine area one by one. In addition to a few technicians such as Du Kai, Xiaoping accompanied others through the two star gates, trekked hundreds of millions of kilometers, came to Am, and lived with them.

Most of the care that Starlink took care of them was passed on through this little girl, which can almost be regarded as a grace of recreation.

The little girl treats them very sincerely, and everyone can feel the desire for them to live a good life. What's more valuable is that she doesn't treat them as patients at all, she takes care of them when she should take care of them, and she is also fierce when she should be trained, just like now, so that they can regain their dignity as normal people.

"Now the city is still small, and when the expansion project is completed, the new immigrants are coming, and there is a traffic police, you, you have to deduct 6 points for this matter! Plus a fine for a fish! ”

Listening to Xiaoping's words again, Du Kai was stunned: "It's normal to deduct points, it's ...... to punish a fish."

"Isn't Gaoquan Farm delivering fish? I saw it, your lady came home with a fish", Xiaoping smiled slyly.

There are also small "bad" places in small cities, Du Kai nodded again and again: "Then it should be punished!" Penalties! Why don't Xiaoping come to my house as a guest? Incidentally charged a fine? ”

"Hey, just kidding, what kind of light bulb am I going to be", Xiaoping waved her hand a little shyly: "I'm going to the farm to see the situation, Sister Xiaohuan is going to shoot a documentary, we have to be ready." ”

Saying goodbye to Xiaoping, Du Kai turned to his place of work, Xiao Huan is really coming, the municipal side can't be sloppy, he decided to cheer up the spirit and make today's inspection work the most perfect.

As the supreme person in charge of Gaoquan Municipal Engineering, Du Kai certainly cannot take care of every screw. In fact, his small municipal team is only a maintenance worker for project management. Most of the work is done by the system itself, and they supervise the process to see if there are any problems, and then regularly check the maintenance effectiveness to see if there are any deviations and omissions.

Manually managing the inspection of the system is a rigorous and continuous task, and everything cannot be left to intelligence. When it comes to one's own safety, the last line of defense must not only be in one's own hands, but also be absolutely reliable.

Du Kai was nervously patrolling, and Xiaoping drove to a large cabin.

After getting out of the car, she shook her head at the scanner above, the hatch opened, and when she entered, the hatch closed, and she pulled the hood-like part of the back of the spacesuit into a flexible helmet, covering her neck and head, and the small box around her waist lit up green. At the same time, the small compartment was pumped into a vacuum, and then the fresh air filled the chamber with fresh air, and only then did the hatch to the interior open.

This process may seem redundant, but it can effectively isolate the inside and outside of the cabin when the shield is damaged, the real-time repair system fails, and the air circulation system fails. Therefore, in Gaoquan City, entering and exiting the capsule still follows the pattern of space life. Even in the future, when this is not usually done, all buildings will still be designed this way, after all, this is not the earth, there is no atmosphere.

"Welcome to visit Gaoquan Farm!"

All the staff of Gaoquan Farm guarded the hatch, shouting slogans, and greeted her respectfully, which made the little girl sigh helplessly, she was only 18 years old, and she was not old enough to do this. (To be continued.) )
