For the construction of the city, Qian Rujun did not get a complete plan, so she was also very vague about the appearance of the city, at most she knew what kind of cooperation she needed.

"Princess, we are going to use iron wire as the main building material, is it okay? We know that on the grassland, iron tools need to be restricted, but iron wire should be fine, right? ”

"We know that the princess can get what the Golden Wheat has from the Golden Wheat anytime and anywhere, but it needs to be prepared in advance and cannot be taken at will. ”

For them, they don't need to know how Qian Rujun did it, they just need to know that Qian Rujun can move things over.

They looked back on the past and guessed what they needed to get the items, but they found that the time it took for Qian Rujun to get different objects seemed to be different, and finally, they concluded that the things to be taken were different, and the princess needed different times, and according to the distance between the origin of the item and Jinmai City, as well as the difficulty of production, the speed at which it could appear on their side was different.

It seems that things are the same thing in the central water tower area.

The purchase from Jinmaicheng means that Qian Rujun must go to Jinmaicheng to pick it up, and as for the money, it must be paid by Qian Rujun.

They knew that the princess was very good at making money, and what he did, if there was no one else in the way, he could make a lot of "money".

Even if you don't get the money directly, but the things you get are almost the same as the money.

There are not many opportunities for rain in the grasslands.

There is no 400 millimeters of rain in a year.

In this area, one might even say desert, there is very little rainfall.

When Emperor Liu Heng of the Han Dynasty was there, the temperature in the north was relatively high and there was more rainfall.

However, the rain in this period is not like the aftermath, most of it is heavy rain, and the rainy days are very few.

In this era, the days of rain can be more than three times as many as in later generations.

Even if it rains a little more, it doesn't exceed too much, and on average, it rains a lot less.

Even if you don't have an umbrella, you won't be able to get wet in the rain on a rainy day in the north.

That's why the stall business in the central water tower area can be so prosperous.

When they consider building materials, they can take this condition into account, they don't need to take into account the problem of rainy days like Guanzhong Chang'an, and they don't need to take into account the problem of drizzle like in the south.

A rain can make a tent made of cowhide be soaked. Thatched houses need to be overhauled after rainy days.

In the eastern part of Yinshan Mountain, even if it occasionally rains heavily, even if the simple earthen house collapses, it is good to rebuild it.

It's a fence, and it needs to be stronger, so you need to use iron wire.

In this place, the house should be easy to dismantle, easy to repair, light is the principle, as long as it can keep warm, so the house made of cowhide is indeed very suitable.

The house they wanted to build for the people in this place was actually the simplest house, but it had to be light and comfortable to live in, so they thought about it for a long time.

It will be cold, so the house must not be ventilated in winter, but in summer, it will be too hot.

How to solve this problem in Dahan? Qian Rujun and the students on Xuetang Island did not know.

Even if they recall their distant childhood memories, they can't come up with a house that can be warm in winter.

In their childhood memories, winters were cold.

Perhaps, they should thank their parents for selling them. They will be able to enjoy the affluent life they have now.

They were sure that they were richer than most of the Great Hans.

This affluence is not only material, but also spiritual.

Steel, grass, and mud are their main building materials.

The reinforcement is used on the outer side of the fence. The walls on this level are relatively high, and there are no windows except in the high places. As for the inner part, the walls can be woven with grass.

They will think of this, it is Qian Rujun once mentioned to them a place where people build houses on the lake, and the building materials for building houses are reeds.

This kind of reed house makes them yearn for it.

Perhaps they could also add some pieces of wood to their building materials, which are made of cowhide or sheepskin.

Cowhide and sheepskin have a better thermal function, and one of the houses must be built in this way.

"You can actually use the kang to keep warm. There are mountains here, so you can have a variety of point trees. There is a lot of water in this river, and it is inexhaustible. ”

Qian Rujun will be able to support hundreds of millions of people in the future, but he can't support millions of people in the upper and lower reaches.

"Also, there are a lot of coal mines around here, you can dig them out so that people can burn them. There is nothing wrong with cutting down trees, what is wrong is that there is a large area of view, not knowing replanting. This part, I can teach you. Also, if it is not necessary, old trees, do not cut them down. ”

As for the city wall, since it is no longer ready to build a high wall, then the best is the wall, and the wall does not need to be built in particular, but when the houses are connected together, it can form a wall.

Therefore, in their imagination, the houses of the prairie are actually not criss-crossed, but a circle by circle, and the concept of a round sky and a round place, which is actually very suitable for the prairie, may make this place a new center of faith for the grassland people.

The sky is round, so that the heaven and the earth are combined with a circle, and the dome of the sky is combined, and the prairie should be round. As for the land, perhaps in the eyes of the prairie people, the land should also be round, and there is no such thing as a square at all, unless there are mountains blocking their view.

If the tent is round and the sky is round, then the city wall should also be round.

Maybe they didn't calculate that the city walls were round, the most economical building materials, but in fact, they did the most labor-saving thing.

Moreover, in their planning, the city wall is actually equal to a part of the house, which belongs to the perimeter of the house, so that it can show a kind of boundary, a kind of distance.

In Qian Rujun's mind, there is a certain image of the concept they put forward.

That's a lot like the appearance of Fujian tulou.

Why are most of Fujian tulou round?

It is because the round tulou can save building materials.

The mountainous areas of western Fujian are poor, and because the mountains are high and the emperor is far away, there are many bandits.

In this era, it is estimated that there are few people on the mountain.

The Hakka people are from the ancient Central Plains and are estimated to still live in the north. It will not be until the time when the Jin Dynasty crosses south will they begin their life of rushing.

If people are rich, they will always think of places where life is more convenient, and over time, places that cannot attract rich people will be filled with poor people.

People will live there, and they are basically poor, so the round one that saves building materials has become the first choice for that place.

There are still square buildings in the mountainous areas of Fujian Province, and those who can afford to build square buildings are basically better off at home.

However, in the mountainous areas of Fujian Province, if we do not rely on the strength of the group, there is almost no way to survive, and the improvement of law and order is still a matter of entering the 20th century.

The tulou is closed, and the way of life inside is impossible for outsiders to know.

For the circular building imagined by the students of Xuetang Island, Qian Rujun is very optimistic.

From their discussions, Qian Rujun can know that it is not impossible to communicate with each other.

There are still many corridors connected between the houses in the outer and inner rings, and these corridors become radial.

However, for the sake of safety, there will be two closed lanes between the large circle and the small circle, forming the outer city and the inner city. This is the concept of the Great Han, Qian Rujun thought about it for a while, and did not force them to give equality to everyone.

At least, the brainwashed Huns are inherently unequal to those who are not brainwashed.

Therefore, a good place should be given to the people who are most likely to be centered on the Han people.

That's the rule of this era.

In Dahan, there has always been inequality between natives and foreigners.

Qian Rujun looked at the city where construction began, 100,000 people worked together, and it was such a simple construction, so the speed was very fast.

The students of Xuetang Island have the experience of building the Chang'an Women's School, and they already know how to make more luxurious and rich decorations, and even all the difficult and ingenious things can't hide from them.

Qian Rujun stood on the hill and looked at the construction site and asked, "What kind of building will it be in the center of the circle?" ”

Since it is a circle, there must be a center of the circle.

If it was a city in later generations, the center of the circle would probably be a lake or a park, but in Dahan, Qian Rujun felt that it would be a building.

A building that represents the highest governing body of the city.

"Tell the princess. In our plan, the center point, we are ready to build a very tall building that can be seen far away.

If there are no mistakes in the design and we can complete the building, we will build a torch in the highest place and let it shine in the night.

As for the source of fire, you can use coal, or you can use wood directly.

This is probably the city's biggest daily expense.

Where there is expenditure, there must be income.

Outside of the city's lighthouse, we will build some floors where you can make money.

To achieve these plans, wood construction is not possible.

Neither can grass,

Mud is not good, only cement can be used.

But for cement buildings to be strong, they need to be reinforced. Even steel bones.

If steel bones were used, we feared that the steppe people would tear down this majestic building.

So we decided to just use rebar. ”

The person who spoke quietly watched to see if Qian Rujun would be angry.

As long as iron and steel are used, Qian Rujun needs help.

Moreover, the Great Han did not provide iron tools to the grasslands.

After a few days of life and consideration of building a city, they learned that the miserable life of the grassland people and the Han people had to pay a little responsibility.

If trade is opened, in fact, everyone's life can be a little better.

After starting the work of building the city, these people began to have the intention of helping the grassland people build a better home.

Building the most suitable city may be a thought process.

"If you want it, as long as you can give a reasonable reason, I will agree to it. ”

The person who spoke was obviously much happier, but he was busy and happy, but the conversation was picked up by someone else.

"Unlike other buildings, half of the cost of building this city is spent on this building. Other houses, when they have money, will naturally build their own homes for the better. Only those who live in the walls cannot renovate the walls. ”

Qian Rujun realized that the building they imagined was estimated to be the same as the dormitory building in the Chang'an Women's School, or even higher than the dormitory building.

Perhaps, the beginning of their idea was a dormitory building.

Any thought must generate needs before it begins to look for a possibility from the existing impression.

"What about the other floors?"

"The other floors will be designed into different functional floors, two of which are commercial and will sell the most noble things, while the lowest floor is an office building, which serves as the administrative center of the place, and the second floor is a restaurant building, which is also convenient for other people to eat here. ”

School Island students, very intimate design.

In this era, many people do not have the habit of eating lunch, and eat at most snacks at noon, but rich people who are not officials do not eat, and there is no place to eat, they go too far outside, bring lunch boxes, and there is no place to steam rice trucks.

"Looks like you're ready to bring in a lot of merchants?" Qian Rujun asked.

She felt that in their conversation, these floors were accommodating a lot of businesses.

To accommodate a lot of businesses, it has to be a big building.

Then, they proposed that the building could spend half of the construction power.

There are more than 100,000 people here, half of the building, whether it is time or materials, it is estimated that it will be considerable, it is estimated that Qian Rujun has to find a way to raise materials as soon as possible, otherwise Jinmai City will not be able to prepare.

"Yes, a city, if there are no merchants, transactions, basically, unqualified cities, can only be said to be a large village, so we are ready to use this commercial building as the core. ”

"Princess, not only are we going to build a house on top of a commercial building, but all the shops are going to be around this building, and there will be a circular road next to it, and there will be a circular road facing this building, and there will be a lot of merchants, and this part of the house is a commercial house. ”

If you concretize this passage into a picture, you will probably be able to understand it.

"Give these Huns, leave some houses, let them have a place to trade, and some houses, so that they can freely come and line up every day to get the right to open shops, and don't give all the benefits to the Han merchants." So that they can find a shop at any time, when they want to buy something. ”

"At the beginning, these shops should be easier to rent, but if you estimate that the shops will be rare in the later stage, you must find a way to make these shops available to those who really need them. This location is estimated to be the most exciting. ”

Qian Rujun knew that when it came to doing business, there was no place where people could compare with the Han people, and it would be too difficult for these grassland people, who were close to primitive people, to compare with the Han merchants.

If it is compared with the merchants of Jinmai City, then it would be good to surrender directly.
