Once they have traveled to another plane, the first thing they have to face is three main problems:

1. Basic living security: no worries about food and clothing.

2. Guarantees against the threat of violence. Whether the threat comes from man or beast.

3. Safeguards against the invasion of the natural world. Bad weather, sickness.

Obviously, most people are more concerned about these immediate issues than the previous problems of the overly specialized industrial system.

Modern society is a highly developed society, with an extremely detailed and specialized social division of labor, and every convenience of life that people are accustomed to, even the simplest and most inconspicuous, requires an entire industrial system to maintain. Before a drop of tap water is released from the tap, it is supported by many industries such as electricity, chemicals, steel manufacturing, cement, construction, and so on.

In Hainan in the 17th century, none of this was possible.

Rice exists in the form of rice. Water, after a simple precipitation, the only way to disinfect it is to boil. Clothes, there is no concept of ready-to-wear, rich people can hire tailors, and ordinary people rely on their wives to cut and sew.

All daily necessities, even the things we are most accustomed to, things that can be obtained cheaply when we walk into any small store, do not exist in that time and space, or rather, exist in a very primitive way.

As the head of the internal affairs team in charge of people's livelihood affairs, Xiao Zishan proposed a catalog of equipment that caused controversy.

"Is it necessary to bring rice mills, flour mills, these grain processing equipment? The problem of spare parts, but also the consumption of electricity...... In ancient times, there were already water-powered rice milling workshops to grind noodles, and many rural people in China still milled wheat by themselves in the fifties. ”

"Well, I think that even if mechanized production is really adopted, it can be completely made by the mechanical department, and it is a bit of a waste of tonnage to bring it from this time and space."

"There are also sewing machines, edging machines, cutting tools...... Team Leader Xiao, are you going to open a garment factory or what? ”

"The agriculture group strongly supports the need for grain processing equipment! If not mentioned by the Internal Affairs Group, the Agriculture Group will also request the purchase of such equipment. Wu Nanhai stood on his side, "Processing speed!" The traditional way of grinding rice noodles is very inefficient, and we eat with hundreds of people, which is too labor-intensive to rely on manual operation. ”

"You can use a water-powered mill, China also has it, and Europe also has ......"

"You'd have to build a mill. The manpower and material resources consumed are not counted? If there is electricity, these equipment can be directly driven, and enough food can be processed in no time. ”

"These mechanical spare parts problems can be solved by the mechanical department." Xiao Zishan had anticipated the questions that this question might cause, and now that Wu Nanhai has an explanation, it will save a lot of effort. "In rural areas, dry grain is generally stored. We are such a crossing group, rationed according to the standards of the Jihua economic era: 12 kg of rice per month for adults. If there are 500 people, at least 6 tons of rice will be supplied per month.

"This 12-kilogram ration is still the standard for ordinary citizens and employees, and the ration of heavy manual workers needs to be increased. There will be a lot of physical work after the crossing, and the amount consumed will have to be calculated according to the figure of 14 kilograms. If we also want to bring in local labor, the supply will have to go up a level.

"The food processed by the machine is of good quality and will not be adulterated with impurities. Stone grinding has high requirements for stone, and if the stone quality is not good, there will be a large amount of crumble in the processed flour, which is very bad for everyone's teeth.

"As for sewing machines, the principle is the same. Sooner or later, the clothes will break down and have to be replaced, who do you expect to make the clothes? Your girlfriend? (laughs)

"Maybe you can ask a local woman, she can't make clothes like ours, it's not difficult to teach her to make clothes, but a hand-sewn garment, no matter how skilled it is, it takes a few days to make it.

"Of course, you may have to wait a few days. The question is that after we have to recruit workers, even," he lowered his voice, "the army." He raised his voice: "The uniform dress of these people also relies on your wives to sew it out stitch by stitch?" (laughs)"

"According to you, the armies of the ancients don't wear clothes anymore, and don't hundreds of thousands of troops change their clothes every year?"

"That's built on the basis of having a lot of cheap, even free, labor. We don't. Xiao Zishan made a heartache, "Our life is limited, and productivity should be more focused on climbing the technology tree." It is better to bring some necessary machinery and equipment directly. It is also possible to provide an engineering sample for future imitations. ”

Housing is another issue of greater concern. The House Affairs Team purchased a large number of tents and set up a tent camp as a transition before the official construction of the house. The proposal of the construction team was to purchase simple houses for direct assembly, which are common on construction sites - as dormitories and office space. There are a variety of board materials, and you can choose according to your needs. It is small in weight, easy to set up, has a certain amount of heat preservation, and is much more comfortable than a tent. Durability too: If properly maintained, seven to eight years of use is not a problem.

"A department of our company has been using the simplest color steel activity room as a warehouse and office space for almost ten years, and it is still in good condition." The person who made the introduction was Aunt Tian's daughter, Li Xiaolu, a thin northern woman, almost thirty years old, fair-skinned, wearing a pair of thin-rimmed glasses, "It can also be made into a building, but it needs to be lightweight." ”

"Because the environment we're dealing with is harsh," her voice is soft and thin, "we can use high-end materials, such as phosphorus and magnesium mobile houses."

"The walls and roofs of this kind of mobile house are made of magnesite composite panels with polystyrene foam pod core, steel doors and windows, and the frame is a light steel keel. No special machinery is required for installation, and skilled workers can assemble a standard room in 4 hours for 4 people using simple tools, which is about 60 square meters.

"Its combination is better than the color steel house, in the longitudinal xiangshang can be arbitrarily added or subtracted a number of groups, the area can be expanded or reduced at will, and the position of the doors, windows and front and rear wall panels in the house can be arbitrarily interchanged. It can also be used to build buildings after strengthening the structure.

"This kind of house has good sealing, thermal insulation, and the house materials are all fireproof materials. Moisture-resistant, anti-corrosion, earthquake-resistant, lightweight, a standard room weighs only 2200 kg. The expected service life is more than ten years.

"Dormitories, offices, and small warehouses can all be used in this type of house."

"What about a factory?" The industry group is more concerned about this issue.

"If it is a large-span factory warehouse, it is not possible, but it can be a simple room with water shabu." Li Xiaolu continued her introduction, "It is actually a simple cement slab house with an angle steel structure. It is much heavier than the average bungalow. The advantage is that the lifespan can be more than twenty years. It can be used to assemble a long-span house, and it can also be used to build a 2-3 storey building. ”

"Cement slab......" someone hesitated.

"The construction team has just discussed that it is not a big problem for us to produce cement and angle steel under our industrial system. If the plant is not particularly urgently needed, you can only bring the drawings and the necessary mold tooling materials, and build it yourself with local materials. "Her face was a little pale." However, installing a simple house is a jishu job, and I suggest sending some people to this kind of simple house company to learn on the spot. ”

Wen Deji nodded, and made a note on the memo: "Practical skills training".

"Can I install water and electricity in a house like this?"

"Yes, although you can't groove and bury pipes in the wall, it's no problem to do wall installation. However, our building team is of the view that there is no separate water supply and drainage system installed in the dormitories and office buildings to save materials.

"For water needs, we believe that it is better to take a separate public washroom, consisting of three parts: a bathroom, a washroom and a toilet. This facilitates the centralized installation of the water supply and water supply system. Considering the problem of rainy weather in Hainan, enclosed corridors will be installed from dormitories, offices to public washrooms so that everyone can use them on rainy days. The temperature in Hainan is not low in winter, so the preliminary design did not consider such a system as bathroom heating. ”

"What about refrigeration? It's very hot in Hainan in the summer. Have air conditioning. ”

This man's speech drew a roll of eyes. But many people's hearts are actually quite optimistic that there is air conditioning: they are used to using air conditioning, and they don't even have an electric fan in Hainan in the Ming Dynasty.

"Traditional air conditioning is definitely not possible." Li Xiaolu glanced at Xiao Zishan, and saw that the host of the meeting did not object, so he continued to talk, "Traditional air conditioners require a lot of electricity and chemical refrigerants. It's a little extravagant for us. If the Executive Committee finally decides to use air conditioning, we have two options available. She seemed a little dizzy, and with another nausea, she stood on the table for a while before continuing:

"One is the wet curtain cooling air conditioner, which is actually the use of evaporative ventilation fans, eliminating the internal fan and compressor, and the refrigerant is water. Electricity is very economical, the disadvantage is that the humidity is high, and the manufacture of this ventilation fan is also quite difficult. ”

"One is groundwater refrigeration and air conditioning, which is similar to heating in principle, except that the steam is replaced by groundwater pumped with a pump. The initial investment of this method is relatively large, and to drill deep wells, the evaporator needs to use copper pipes. ”

"Personally, I prefer the second one, which has more effects than the previous one. The system is also relatively simple. ”

"This kind of air conditioning is not allowed in the country, right? Say it's a waste of water. ”

"Damn, there's no such rule on the other plane."

"Well, I know. But wasting water is still the same, it's not environmentally friendly. ”

"At that time, you were still in charge of environmental protection?"

"You can refill the groundwater, so there's no waste." "If you want to be a little more advanced, you can also use ground energy air conditioning. The way is similar to the second one. The depth of 10 meters underground is generally at a constant temperature of about 20 degrees. This depth is reached by drilling holes, and then circulating water underground and in buildings as a heat exchange medium to achieve warm in winter and cool in summer. In winter, heat is taken from the ground, and in summer, heat is released from the ground. Of course, our camp had to be on a foundation with a relatively stable geological structure. If it's too active, it's only heated. ”

The eyes of the participants were all on Xiao Zishan, who was in charge of internal affairs, and Xiao Zishan on the chairman, Wen Desi. From the bottom of his heart, he was in favor of everything that would improve the living conditions of the traversers. He understands the basic truth that it is easy to move from thrift to luxury, and from luxury to thrift, a group of urban people, most of whom are pampered, will start over in a barren place, and the living conditions are too difficult to cause demoralization.

But he did not dare to openly state that such a system of life would involve the use of a large amount of industrial resources, and he really did not have the courage to say anything in favor of it.

Wen Deji made eye contact with him for a while, and then looked at the leaders of each group for a long time, and Zuihou said a classic line:

"Let's study this issue again."
