Of course, this pressure cooker is not an ordinary civilian pressure cooker, and the pressure must reach at least 110 atmospheres.

In this era, it is still very difficult, this thing is back to the original point, Huo Gang suddenly felt that it seemed that it was easier to directly raise the temperature to 1700 degrees Celsius, because Huo Gang The temperature of their steelmaking can almost reach 2000 degrees Celsius, so the temperature of 1700 degrees Celsius can be easily reached.

It's much simpler than making soda ash.

However, three acids and two alkalis are necessary for the start of the chemical industry, since it has been written, Huo Gang naturally cannot throw it away like this, forget it, when the time comes, Huo Gang will hand it over to Sun Er and them to study it.

Sun Er: They estimate that it will be more difficult to study, but others should be fine.

Huo Gang basically stopped when he wrote this, and it happened that Xia Zhu's voice came from outside, and soon Cailian followed Xia Zhu in.

"I've seen the chief."

"Excuse me, sit, I have some things to know, how much does it cost to plan a house for the ordinary situation of Yumen Pass?" Huo Gang asked directly.

Although Cailian is responsible for Yumen Pass and the transaction between Yumen Pass and the Li family in Longxi, because Yumen Pass has already begun to plan, these works are naturally within the planning scope of Cailian.

"Looking back, according to the cost of cement that we have sorted out so far, our main cost is labor cost, as well as the cost of calcined coal, and the cost of transportation."

"After accounting, our current cost of a ton of cement is about 30 yuan."

"According to our current plan, if the house you mentioned before adopts a two-story small building, with a single-story area of 100 square meters, and the surrounding walls are made of fired brick walls, and the partition needs concrete, it will take about 30 tons of cement, which is 900 yuan. In addition, the cost of fired bricks, sand and gravel, plus if you say that you want to add steel bars, is about 3,000 yuan. Cailian told Huo Gang the approximate cost.

The price of 3,000 yuan food stamps is Huo Gang's cost price, and they will basically not make a profit. Of course, Huo Gang was not prepared to make money from this.

"If we spend this money, can we hold it?" Huo Gang thought for a while and asked.

"No problem, our other products are constantly creating value, and the grain has been being transported from the Li family in Longxi, at present, the grain in our territory is probably enough for all of us to eat for a year, which does not count our grain harvest this year, because we can't predict how much grain this year will have, and there is still food coming in later." Cailian said.

"There won't be much food behind it." Huo Gang shook his head, now that the time has entered June, the entire Western Regions has begun to become hot, according to this time, there is already a drought in the Guanzhong area, that is to say, the shortage of food in Guanzhong is estimated to break out soon.

Although it is said that this year is not a great famine, and Datang still has huge grain-producing areas in the Central Plains and other places, but in the case of famine itself, Li Shimin will definitely not allow a large amount of grain to be sold to Huo Gang.

You don't need to think about the amount of grain in the back to know that it will be very small, and some merchants may be able to sell some grain from Gaochang and other countries, but this part of the grain is not much.

Of course, these grains are enough for Huo Gang, and at present, the land planted on the first line of the entire Yumen Guanyang Pass is 120,000 mu, and the output of Datang grain is about one stone.

Huo Gang chose wheat for the grain here, because they lack water here, and it is not realistic to grow rice, so these cultivated fields are planted with wheat, and the wheat in this period is naturally incomparable with the wheat in later generations.

The yield of wheat per mu in Datang is basically about one stone, and some good fields can reach two stones, which is already the limit. Although the land here in Yumen Pass is barren, considering the effect of improving grain in the spiritual spring water, coupled with the crazy performance of these alfalfa grasses before, Huo Gang's requirements are not high, not to mention that these wheats can catch up with the wheat production of later generations.

It should be no problem for these wheat to yield two stones per acre, right? Because Huo Gang's current acre of land is about 166 square meters less than that of one acre in later generations, and his acre of land is only 500 square meters, so the number of two stones is not to mention.

120,000 mu, which is about 240,000 stone of grain.

In this era, according to the current statistics of Huo Gang, the food consumed by a heavy physical force in a month basically reaches one stone, with an average of 2 kilograms of grain per day, because there are almost no concepts such as vegetables in this era, and meat is not to be thought about, all nutrition depends on a variety of staple foods.

And if it is not heavy labor, although it can't consume one stone per month, it will be at least half, but considering that his own power must need some grain reserves, so according to one person's one stone of grain per month, each person is 12 stone a year, and Huo Gang's current subordinates are calculated according to a population of 200,000, and the grain consumed in a year is about 2.4 million stone of grain.

At present, the food in Huo Gang's hands is enough for everyone to eat for a year and a half, that is, there is no problem in getting through this winter.

And there is another problem that has to be taken into account, that is, Huo Gang and they have been constantly taking care of food for these ordinary people recently, as well as exchanging food, which means that the original food in the hands of these ordinary people has been stored.

The original grain stored in the Turks, Yiwu, and Loulan was almost close to a year's ration, and if these were counted, the food in Huo Gang's hands was enough for everyone to eat for two years.

So in the future, there is no need to worry about the food problem this year, the reason why we can't grow too much food this year is because this year's land is a little late, and when next year, the land allocated to each family, they will definitely dig a few acres of land to grow food.

According to the calculation of 4 people in each family, Huo Gang gave them 20 acres of land, and if they planted half of the land into grain next year, an average of 2.5 acres per person, then 200,000 people, next year will be 500,000 mu, and the output of one million stones a year will be 1 million stones.

This is the herdsmen's own grain, and this is not counting Huo Gang's grain, after the end of this year, Huo Gang will hand over the official fields to these farmers to plant. Moreover, the industrial city will need more and more workers who will earn more than enough food each year to feed their own land.

In this day and age, what country dares to say that all its people are well fed?

When these people have money in their hands, they will think about spending to make their lives better, and they will save some food, but not too much. If you think about it in this way, Huo Gang's plan can be implemented.

"If these people pay back the 3,000 yuan to us within 10 years, will they be able to afford it?" Huo Gang looked at Cailian and asked.

"There is no problem, 3,000 yuan for 10 years, they only need to pay us back 25 yuan every month, according to all our current labor estimates, their daily salary is 4 yuan, a monthly salary is 120 yuan, and many families are two people working, especially after our textile mill and weaving factory are established, too many women also have jobs, this salary is not a problem for them." Cailian said very dryly.

"Very well, just follow this plan, and divide the house assigned to them into five specifications. The most common is an ordinary person's house, the single floor of the house covers an area of 100 square meters, and the two floors are 200 square meters, which is enough for each family. In addition, the yard reserved for them is a total of 300 square meters. This is the most basic. ”

"In addition, there are fifth-level craftsmen and fourth-level craftsmen who have doubled their size. The third-level craftsman has a three-in, three-out yard, the second-level craftsman has a five-entry yard, and the first-level craftsman has a seven-entry yard. Huo Gang added.

"Remember, when you become a craftsman, we pay for all the houses, and they just need to maintain them themselves."

In addition, the salary is also divided according to the level of craftsmen, the basic labor workers are paid according to the salary of 8 yuan per day, and above the labor is the junior skilled workers, 10 yuan per day, the intermediate skilled workers 12 yuan, and the senior skilled workers 14 yuan. On top of that, there are 20 craftsmen per day, 30 craftsmen at the fifth level, 50 craftsmen at the fourth level, 80 craftsmen at the third level, 100 craftsmen at the second level, and 200 craftsmen at the first level. Huo Gang first formulated the standards he had in mind.

This seems very high, but in fact, this salary is not high at all, because there are only a few people who can get the salary of second-level craftsmen, and it is estimated that there will be no first-level craftsmen.

If Lu Ji, the highest level among these craftsmen, did not admit that he was a first-class craftsman, no other craftsmen would have that qualification.

Of course, Huo Gang can grant them that qualification, because the rewards of these craftsmen are equivalent to the example that Huo Gang will set for others in the future, only in this way encourage these craftsmen to learn and create inventions, and these sparks left by Huo Gang will burst out with the brilliance of civilization.

It's been almost half a year since he came to this world, and Huo Gang has discovered that the wisdom of these ancient craftsmen really can't be underestimated, and now these craftsmen of his are some basic craftsmen, but in this era, there are really some people who are from famous families, but they are only interested in the things of these craftsmen.

No one supported these people before, but Huo Gang was willing to support them, although Huo Gang couldn't attract them for the time being, but sooner or later Huo Gang would attract these people.

The standards should be set early, and even these wages will definitely be a little low by then.

"According to this standard, the salary is divided into 10 grades, and all other officials and soldiers are applied in the future. From the next month onwards, all salaries are paid. Huo Gang thought for a while and said.

"Yes, but you still need to specify the salary of the soldiers." Cailian nodded immediately.
