Yang Minghuan was a little depressed, "No, isn't there often people in our old time and space who spend a lot of money to buy seafood that comes by air?" ”

"This is true, but the problem is that the seafood in the old time and space was also made with a lot of spices and oils, and now we can only process all the seafood and throw it in the rice to cook paella or boil seafood porridge, and the salt is not enough, and it is simply a crime to eat. Not to mention seasonings like soy sauce, we didn't have enough to bring. ”

"So do you have any suggestions?" Yang Minghuan eats seafood on weekdays, and he has been looking forward to changing the taste for a long time, so he hurriedly asked Sun Wenbin at this time.

Sun Wenbin shrugged his shoulders. "First of all, the first thing is to stabilize the source of salt, just now Shi Li from the chemical group also came to me, saying that without salt, the chemical team would not be able to carry out its work, and they would not be able to ask us to use salt to make industrial products. The second is to determine the source of the food, and I have now opened up a field with the captives to grow a lot of sweet potatoes and potatoes, but it will take at least three months for these little things to mature. If I hadn't added so many mouths today and survived until that time, you would have given me food to support more than 2,000 people now, and we would have to get food from the outside world. ”

Yang Minghuan couldn't help but cover his face with both hands...... "Meow! I can't live, I don't have enough money before I cross, and I don't have enough food after crossing...... Do we have enough of it? ”

"Yes......" The crowd turned their heads to the place where the sound came from. It was Cheng Jun, who was still weak in his legs at this time, and in order to prevent himself from falling to the ground, he sat on the armrest of the sofa next to him. "We come from the future! Our scientific knowledge is far beyond this era, and we can do anything as long as we have the conditions! Let's just talk about salt, salt is an indispensable thing for human survival, didn't it say some time ago that there is a salt field in the north of us? Let's not talk about grabbing it, we can buy it. In addition, when it comes to food, we can find a local area to buy it, and exchange it for a trade. I can't let myself starve to death with my captives. ”

"That's right, there's a saltworks to the north of us, and it's like there's a village, what's it called?" Du Yande hesitated for a moment, but for a while, no matter how hard he tried, he couldn't remember the name of the village.

"The captive seems to be called Yancun ...... directly" Sun Wenbin checked the interrogation records, but he still remembers this vividly.

Yang Minghuan smiled, "It's really uncreative, let's send someone over there tomorrow to take a look, and let the reconnaissance team go over and have a look first." ”

Cheng Jun stood up and rubbed his legs, which were still weak. "So can I go over and have a look? Li Zhe from the technical department has been telling me for a long time, and he has always wanted to see how salt is made in this era. ”

"Yes, in addition, let's just send a combat team over tomorrow, and if you encounter resistance or something, you can quickly clean up the resistance." Du Yande heard the gunfire outside for most of the day today, and he didn't feel safe at all.

"Don't worry about this, I think all the capable soldiers in this place have been defeated today, and there will be no more enemies. The only thing to worry about is that the army sent by the court of the Wu Dynasty will be suppressed, and at that time it will be hundreds of thousands of troops......" The voice came from next door, and everyone couldn't help but be a little stunned.

Next door was Liu Yeqiang, who was wearing glasses and writing things down in his notebook. "However, to dispatch an army of tens of thousands of people, the emperor needs to authorize, the ancients did not have our radio station, we have to send it to Beijing through the post station one station at a time, and then wait for the cabinet and other officials to quarrel, and then send someone down to verify the investigation, and then report back, and then quarrel, and finally decide whether to send troops to suppress it, at this time it is generally a matter of about a year, and we are enough to complete the civil buildings and basic industrial construction required for ordinary life during this time."

Yang Minghuan could hear Liu Yeqiang's voice, and asked directly through the wall: "Then you mean that it is basically impossible for us to be attacked by the Wu Dynasty army during this time?" ”

"I think it's 90 percent likely. So don't worry too much about the counterattack of the Wu Dynasty, now you can focus on construction, and also, we have so much labor now, do we want to get that tap water system right? ”

"Huh?" Everyone in the house was in a daze, "Isn't the water in our drinking place now still tap water?" ”

"Of course not, now because they are building houses, the construction team has come to me several times and asked me to approve the project of the waterworks, and I have forgotten about ......it in the past few days" Yang Minghuan is now quite embarrassed, and actually neglected the most important drinking water safety in eating, drinking, and Lazar.

This is Liu Yeqiang walking into the office of the executive committee with a design drawing. "This is a drawing of a tap water filtration system I designed the other day."

"Can't you just extract groundwater?"

"No," Liu Yeqiang replied quite simply, "The groundwater on this seaside contains salt, and the content is relatively high, which is not suitable for drinking water, and the water we have been drinking for more than ten days has been directly imported from the Dongfeng." ”

"Won't it?" Du Yande jumped up, "Are you saying that you have been using auxiliary machines to control the light for more than ten days?" Oh, my God! He exclaimed again and again, leaving the people in the office baffled. I'll it! It's turning diesel into water! We may not be able to build the petrochemical system in the past ten years, this diesel is easy to turn into water, but there is no diesel flowing in the river! ”

"It's not that scary, I modified the desalination equipment on the ship, using an electric RO desalination system. As for electricity, anyway, the ship has a large area, and a solar power generation system is directly installed, and before the hydropower is installed, a large part of the daily electricity in the base is provided by solar energy. In addition, wind power has been installed on the beach, and now it is basically environmentally friendly electricity. Liu Yeqiang seemed to anticipate Du Yande's reaction, and explained slowly. However, after all, the use of RO desalination water will still consume the life of the reverse osmosis membrane, but it is relatively much better than direct electrolysis or host cooling and desalination. ”

In order to save fuel, he has even asked Zhang Yuan to design a solar power system that can be installed in the car, which is used for commuting between the camp and the brick factory. At this time, if you have been using diesel for more than ten days, you have to have a heart attack attempt.

At this time, everyone gathered around the drawings spread out on the desk by Liu Yeqiang, and sighed from time to time, Liu Yeqiang, a professional designer, decomposed every part of the entire waterworks in detail on the drawings: sedimentation tank, filtration tank, disinfection tank, canal, water supply tower......

"We've seen the river next to it, the amount of water is not small, and the self-purification ability should be very good, right, is it necessary to use so many things? We now lack building materials, cement can not be produced by ourselves, just rely on bricks to build? ”

"The amount of water in this river is indeed not small, and I originally thought that there would be no pollution in this river without modern fertilizer pollution, but a few days ago Wang Yizhi, who was in charge of water quality inspection, checked the water quality, although there is not much sediment in the water, but there are a lot of algae, indicating that the organic matter content in the water is still relatively high. There are no chemical fertilizers in this space, so there is only one reason, there must be large-scale agricultural areas or residential areas upstream. ”

"That means you can't drink this water?"

"Of course, you can't drink it directly, and the test report given by Wang Yizhi says that this should belong to three types of water."

"The quality of the three types of water is good, and I remember that the water quality of some waterworks is not at this level."

"That's right, but we have to know how many steps the tap water in the world we come from has to go through to purify? We can't purify tap water with chlorine right now. ”

"It's not a big deal, is it? When the chemical plant is put into operation, can't you just put chlorine gas into the pool? ”

Liu Yeqiang suddenly rolled his eyes, "You're asking everyone to drink dilute hydrochloric acid, not purifying tap water." ”

There was a burst of laughter in the office. Liu Yeqiang pointed to the drawings, "The brick factory now discards a lot of bricks every day, and it is already piled up, and these bricks can be used to make cement ......."

"What??" Everyone was stunned. "Bricks can make cement??"

"That's right," Liu Yeqiang nodded leisurely. "The main problem now is that there is no coal, lime needs coal, steelmaking needs coal, and coal is needed to burn cement, and I think the biggest obstacle in the industry is the shortage of coal. Now that shallow coal has been discovered in the north, we should free up some of our efforts to mine coal. ”

"Now there are things everywhere that need to be developed, the coal is scattered after it is mined, we don't have wagons to transport it, and now if we go to mine coal, it will not only occupy manpower and transportation capacity, but also need to open a new defense zone, which is not feasible until the captives are completely absorbed." Du Yande analyzed. "What we can do now is to go to the salt village tomorrow to confirm how much salt we can buy."

"Indeed," Liu Yeqiang responded, "salt is a good thing, and since ancient times, salt and iron have been very important means to control and rule, and the sale of smuggled salt has been a matter of repeated prohibitions from ancient times to the present, so it can be seen how great the benefits are during the period." I would even go so far as to assert that the smuggling of this salt alone would have met the needs of the grain trade. After solving the problem of food, I think we will be able to spare some of our energy to mine coal, right? ”

"If you have to cross the river to the north, and there are no wagons to transport it, how can you bring back the coal you have mined?" Questions were raised.

Liu Yeqiang opened another map, "After crossing the river, there is a plain, where we can build a new industrial base near the sea, and the mined coal will be transported there directly for coal preparation, and then a coking plant, a cement plant, and a steel plant will be built directly there." It would be enough to ship the finished product back and, if possible, set up a new shipping port directly there. ”

Du Yande, Yang Minghuan, and Sun Wenbin looked at the map carefully and felt that it was feasible, "That's it, Liu Yeqiang, you write a plan first, submit it to the executive committee, and then we will send a military team with surveyors to go there to investigate on the spot and then make a decision." ”
