Zhang Dong serves Huang Yi almost every day. He is very studious and likes to think.
He felt that fire guns should be developed to hit farther and more accurately, and asked Huang Yi why he didn't make as many good fire guns as possible.
Huang Yi didn't want to make as many miniguns as possible, but it was a pity that conditions did not allow it. However, with the improvement of steel quality and the improvement of manufacturing technology, it was not impossible.
It's just impossible to predict how long it will take.
The top priority is to focus on the development of muskets, and strive to increase the firing rate of flintlock muskets within one or two years, so that all musketeers can use flintlock muskets that are much more convenient than matchlocks.
The base area had a lot of people, cars, and livestock, so we didn't give up digging coal and transporting it to Zhangjiakou in exchange for food and supplies.
Because the relationship with Li Weida has gone further, the Li family gave up the profits and did not even plan to make profits from selling coal, as long as they did not repay the money.
Last month, settlement with the base began in exchange for one pound of wheat for twelve pounds of high-quality coal.
Anyway, every ten or eight days, the base area will send a hundred carts of coal to Zhangjiakou. When the trucks come back, they always bring various goods purchased from Zhangjiakou.
At the beginning, bamboo and steel were purchased the most, followed by grain, cotton, and pots and pans.
After roasting, moso bamboo is prepared to be used to pour concrete instead of steel bars.
There are a lot of limestone, clay and iron slag required to make cement, and there are sufficient coal resources, so the output of cement can basically meet the needs.
The houses in the base area are all made of stone, and the foundations must of course be poured with concrete to form two ring beams each one foot high and as wide as the wall. The two ring beams are four feet apart.
This kind of house is strong, earthquake-resistant, and has a service life of up to a hundred years.
Building a city cannot be accomplished overnight. In order to prevent the base area from being attacked by large groups of enemies, Huang Yi decided to build a single wall one foot and two inches high and one foot and two inches thick.
Ancient Chinese city walls were very thick, with many of them exceeding ten meters at the bottom and between six and nine meters at the top.
The cities planned in the base area are all concrete structures with inner and outer walls one foot and two inches thick. The inner and outer walls are separated by more than five meters. There are concrete beams and cross beams between the two walls to strengthen them. They will later be filled with gravel, slag, and coal. Gangue and so on.
After all is completed, the height of the base city pool will be three feet and three feet, the thickness will be one foot and six feet, and the circumference will be eight miles.
Even though we know the historical trends, we still have to prevent accidents.
In order for the base area to resist cavalry raids and prevent Tatars or slaves from plundering the entire year's harvest.
The exterior wall, which is one foot two feet high and eight miles in circumference, must be completed after this fall.
Surrounded by this single wall, Huang Yi led hundreds of archers and hundreds of musketeers to garrison, and thousands of Tatars and Jiannu without cannons could not defeat it.
At this time, pollution issues were not considered at all, except that cement kilns, lime kilns, and brick and tile kilns were located within five miles of the suburbs.
Steel factories, quilt factories, shoe factories, equipment workshops, etc. Anyway, all the workshops and local factories are in the city.
Several concrete silos capable of storing five thousand kilograms of grain will be built in the city before the autumn harvest.
Huang Yi can draw the silo drawings.
The silos in the base area were not the kind that could easily store tens of thousands of tons in later generations. They could only store three to four hundred tons of grain.
This kind of silo would not be worth mentioning in later generations, but it is definitely a proud landmark at this time.
There is concrete and there are bamboo bars instead of steel bars.
The silo designed by Huang Yi has a circumference of fifteen steps and a height of four feet. Its service life cannot be less than seventy years.
With moth-proof and mildew-proof silos, in the dry and cold climate of the north, the loss of stored grain will definitely be close to or even exceed the inspection standards of later generations of grain depots.
Food can save lives and is so important.
Therefore, it is not only necessary to capture the harvest to ensure that the grains are returned to the warehouse, but also to eliminate all unnecessary losses.
Book friends, please do not think that the city to be built in the base is very big. In fact, the cities in ancient times were not very big. A city of three miles or a country of seven miles would be considered a big city.
A mile in the Ming Dynasty was more than 500 meters long, and a city with a circumference of eight miles covered an area just over one square kilometer, which was almost the same as a larger community in later generations.
In fact, if all the manpower is concentrated to build the city, it is fully capable of being completed after autumn.
But there is no need to do this, because it is known that the Jin Army will not care about Hu Duntu's side in the past two years.
The city in the base area has a four-meter-high wall, which is enough to defend against cavalry raids.
The top priority is to solve the problem of basic necessities, food, housing and transportation and improve the quality of life of all people.
Because cotton and cotton cloth are purchased in large quantities, and because there is no shortage of wool, sheepskin, and cowhide on the prairie, there is no one in the base area who is not naked.
Everyone has at least one pair of cotton-padded clothes and one quilt, and most young adults also own a set of white sweaters and trousers, and more than one pair of sheepskin riding boots or cowhide cotton shoes.
The basic necessities of food, clothing, housing and transportation are basically solved, and the food problem is no less than 80% full, with some meat every now and then.
There is no shortage of cattle and horses in the base area, there are many large vehicles, and there are carriages to pick up and drop off work places far away.
The only problem that has not been completely solved is housing, because there are still many people crowded in yurts.
After the busy spring plowing, the most important task is to build a large number of warm and well-insulated houses that can accommodate everyone.
Of course, it is impossible to have excessively high living conditions these days, and it is enough to just meet the most basic needs.
People who have started a family have their own small home, and the rest are guaranteed to live in warm dormitories.
Each dormitory must build a heated kang to accommodate twenty people.
Small families are usually allocated an inner and outer room, with the inner room being a bedroom and a heated kang that can sleep seven or eight people.
In winter, not just winter, as long as it was too cold to farm, in principle everyone lived in the city.
Food, daily necessities, bedding, clothes, etc. had to be stored in homes in the city. Those who did not have a family were of course stored in collective dormitories.
Of course, you have to go out of the city to farm, but some fields are far away from the city, so going back and forth every day wastes time.
Therefore, it is necessary to build ten or twenty collective dormitories for centralized living.
Dormitories outside the city only need to be sheltered from wind and rain and can make fires for cooking. They are temporary buildings and cannot be occupied in winter.
The centralized living method was adopted from the beginning not only for the convenience of management, but also for preparation for war.
It is conceivable that the base area will definitely be attacked.
According to the Jiannu's habit of sending troops, the war basically started after autumn.
When they come to the base area, they must ensure that they cannot grab a grain of grain, a piece of property, or capture a Han citizen.
This would at least ensure that the slaves could not coerce the captured Han people to participate in the siege and serve as cannon fodder.
They had come a long way and were unable to complete supplies through looting, so they were destined to suffer a loss.
If they fail to attack the city and lose troops and generals, their national strength may not be able to bear it. It is a question whether they will come again in the future and whether they are willing to go on an expedition.
