When the wound is injured, it is always little by little, slowly squirming when it is recovering. When Qian Rujun followed Chun Yuyi, he saw many wounds.

Although it was her students who studied, Qian Rujun also followed suit.

Looking at the long river, Qian Rujun wanted to take a boat down the river and see the beautiful riverside scenery.

She thinks that before stepping out, she should take a good look at the scenery of Dahan, and let more people live in the space, so that when she goes out to travel, she can sprinkle people at any time and build more Dahan villages.

Culture can only spread if it occupies more places.

Qian Rujun likes that there are people everywhere who can communicate.

But she doesn't like to learn foreign languages.

So she likes to brainwash the grassland people and teach them the popular words of Guanzhong Chang'an.

Now, in Jinmaicheng, Guanzhong Chang'an is the most common language.

The appearance of Metroidvania, from the outside to the inside, is like a milky bug, constantly spreading and growing taller. Of course, Metroidvania will not grow too tall, except for more than a thousand water towers, only the central tower can be proud of this vast world.

As far as the eye can see across the grassland, the horizon is the farthest you can see.

Yin Mountain is next to it, so there is a side of the horizon that they can't see.

The eyes of the grassland people, in this high city that is the most magnificent in their eyes, Qian Rujun's eyes often look outside the city.

There are more than a thousand places in the whole city, wriggling nodes. Because all the work is going on around the students of this school island.

This city, from these thousand nodes, gradually spread outward.

At first, I couldn't see what the new city looked like. But gradually, you can already see its outline.

Half a month later......

Gradually, the future of Metroidvania has been seen, and apart from the tower in the middle, there is also the outer earthwork used as a city wall, and the rest of the place is almost completely new.

By the way, because it is more difficult to peel fur, and Qian Rujun found that there are so many houses, the fur is not enough, so Qian Rujun asked people to go out and rob again.

The target this time is mainly cattle and sheep, and if you accidentally bring people back, you can only brainwash.

At this stage, Qian Rujun does not want too many uncontrolled freemen.

If there were more freemen, they would want to take back control from the Han Chinese.

They don't know that the first person is the one who has been brainwashed and will not betray. The last two people will definitely fight, and for Qian Rujun, she can't afford the damage of the fight.

These hundreds of thousands of foreigners who used to be called Huns and are now called steppe people have also lived in built houses, and for them there is a space to nest, which has made them very happy, although the outside is still being built, but the warm air inside is much better than living in a tent outside.

Once inside, they hardly want to come out.

Unfortunately, they have a higher authority controller in their heads. They had to come out.

What's more, the city has not only built circles on the surface buildings, but also in the corners of the underpasses that they can't see.

On the lower floor of the building, there is a circle. As for the streets of the city, they did not bother to build bricks, but laid them all with cement.

Cement is a building pattern that hurts horses' hooves, so if they're smart enough, they won't ride horses in.

The horses they are currently riding do not belong to them, but to Qian Rujun.

The circle under the building is special.

This ring is a tube, and this tube is not made of ordinary clay natives, but is made of copper.

Copper is a precious item in the Han Dynasty and elsewhere.

In Dahan, there are not many copper mines that have been mined.

There are not many copper coins minted.

Now, history should have developed to the point where Deng Tong went to Shu to dig copper mines, and Wu also began to dig copper mines in Chu.

Since the crown prince still beat the crown prince of Wu to death, the rebellion of Wu seems to be doomed. There is no way to change it.

Copper pipe is a precious material for the Han Dynasty, if the Han people, or ordinary grassland people, see the copper pipe, it is estimated that they will immediately become thieves digging copper pipes.

If Qian Rujun had not developed the most meticulous orders. This kind of thing is bound to happen.

You know, in this day and age, copper is money.

If you want more money, you go to copper mines.

If you dig it, you will become rich.

It's the same as digging for diamonds in the future.

This matter cannot be known to the Firehead Army.

Therefore, Qian Rujun didn't let the Huotou Army know, or even let the people of the grassland who were brainwashed by her management know.

Qian Rujun doesn't know how greedy people have to be to surpass the shackles of brainwashing, she doesn't want to take risks, and for this city, the existence of copper pipes is a very important foundation. If it is dug up, the periphery of the city will be destroyed.

Therefore, she is leading the students of Xuetang Island to do this job herself.

No matter how powerful it is, the students of Xuetang Island are still people, and they can't move too heavy things.

In order to allow students to move copper pipes, each section of copper pipes is not too large, and it is the distance that people can transport.

It is very difficult to go to the copper mine, there is no copper mine near Galaxy City, and these copper mines must be smelted and cast into copper pipes.

In the absence of a choice, Qian Rujun had no choice but to let the people of Jinmai City, combined with the ability of Qinhuangdao, dig out the copper mines in Liaodong.

In fact, she knows that the island country has more copper, but this copper is not suitable, and shipping is still too dangerous in this era.

Moreover, the island nation is too far away.

The island people of this era don't know what kind of people they are.

Qian Rujun asked someone to do this very early.

The goal is to build a new city, which is in the north, but not Metroidvania.

The copper pipes are transported through the space, so all the students have to do is to connect the copper pipes, and more than 1,000 students can connect more than 1,000 copper pipes, so they can work together. After all, the city doesn't have more than a thousand laps.

However, the copper pipe is very heavy, so it is well jointed and not easy to move. There are no big appliances in the grassland. So when you start putting the first circle, you have to measure it well.

But once you start to put the circle, basically the rest of the work is easy to do.

Finally, the copper tube forms a large circle.

There are more than 50 circles inside and outside the city, and some copper pipes are still outside the city, ready to wait for the expansion of the city, in accordance with the copper pipes, this part, has left a pattern in the galaxy City, I hope that the people behind can do the same. Now, on top of the copper pipes, it is possible to build a house.

After the copper pipe was built, a layer of rubber was added to the outer ring to make the appearance of the copper pipe disguised, but the heat could still be conducted, and finally soil was spread on it, which was Qian Rujun's improved ondol.

The fire kang was lit outside the city, and in order to prevent the air in the city from being polluted, many polluting buildings were outside the city.

People gather together will pollute the city, measures to reduce pollution must be done in the city, the Yellow River in this era, the self-purification capacity is okay, the comparative population in this era is still very small.

Therefore, most people, including Chang'an City, have not treated sewage much.

But Qian Rujun knows that the sewage created by so many people can make this place stink.

The smell is not tight, and the smell is easy to breed mosquitoes and flies, and mosquitoes and flies can bring diseases.

Even though there are not many concrete buildings in the city, the presence of people is a source of pollution, including equipment such as baths, which need to be piped clearly and separated.

There is indeed an advantage to separating the water, some of the water can be reused.

The construction of Galaxy City, the most time-consuming and labor-intensive, is not the construction above ground, but the construction underground, and there are infinite pipelines underground.

Wastewater, clean water, and fertilizer pipes are basically newly built pipelines by ordinary people.

Of course, these pipes must avoid copper pipes, and it is not easy to avoid them, so Qian Rujun left copper pipes at the end.

All this must be carefully calculated.

When the underground pipeline was completed, Qian Rujun felt that the city was almost finished. All that remains is the central tower.

Whether it is the source of fire at a high place or the strength of the building, it is a very difficult thing.

When the students of Xuetang Island built the city again, it was not as easy as it seemed.

The city's tap water is a new measure.

The way tap water is transported into the city is underground, not above ground, and there are pipelines buried underground, so that this tap water can flow in and block the wind and sand above.

This is the idea that Qian Rujun got from the qanats. She told the students about the school, and they immediately designed it.

This is a new city, built for foreigners, but it is the best way to show their talents.

Dahan's ban made them think of various ways to solve the problem.

When the water comes in, when it reaches the small water tower in one of the 100 places in the city, there will be a waterwheel to carry the water up to the water tower above.

The water tower then transports the water to every house.

The cost of repairs for the operation of this water tower is the responsibility of the city, so the residents who live in the city must pay taxes.

After all, living in this city, it is impossible not to enjoy these public facilities, as for the public facilities, the bathhouse, in addition to the basic bathing equipment, there are more high-end compartments, which allow them to do higher enjoyment, but if they want to enjoy a more high-end room, he has to pay, so they must have the ability to make money.

They can enjoy washing the quilt by the pool and drinking, eating, drinking.

As for women, Qian Rujun is impossible to arrange for them to appear, and as for what they will do later, it is not up to Qian Rujun to manage it.

There will be such a facility, because Qian Rujun thought of the Roman Empire, they used to use the bathhouse as a public saloon.

Qian Rujun thinks that maybe this place can also become a public saloon on the grassland.

After all, when one person is naked, he is best able to speak with an open heart and without a knife in his hand, and for most people, it becomes a luxury to want to defeat another person.

Having a weapon can still bring more courage to a person.

Even if people who accept Qian Rujun's brainwashing, there will still be conflicts between them, and there will still be disputes that cannot be resolved.

How to solve these problems?

Qian Rujun will exhaust himself if he comes forward!

So Qian Rujun thought of the court and the court.

It is not difficult to arbitrate a matter, but if someone wants to do something bad and does not let others know, then the dishonest person will often become the best offender.

People don't like to cheat people, but it's easy to find that when you cheat, you can often get more things.

Honesty and credibility are the most important capital of a person, which is based on the fact that everyone will not leave the place where they live too far, a person will survive in a place for a long time, if there is no credit, life here will become very miserable.

But Qian Rujun can be sure that in this city of the grassland, it will not be the world of acquaintances, but a place where many strangers gather, and the grassland people are used to wandering, and they have no way to stay in one place for too long.

Their personalities are actually similar to her, and Qian Rujun's personality is also like floating clouds, always like to float around.

If you stay in one place for a long time, you will want to find a place to go out and do activities.

In this case, you can only become a merchant of the steppe.

Businessmen are the most profitable people, and Qian Rujun doesn't want to give the right to do business to these grassland people.

Why are Hui people unwilling to work hard? Qian Rujun thought of a problem she encountered when she talked to her sister in Xinjiang Province in later generations.

She always complained that the people of Xinjiang Province would only hold their flocks, and they would not care about the welfare given to them by the government, and even take the seeds of fruit trees they gave them to eat.

For them, it seems that they don't have to do anything else to be fed and clothed.

Qian Rujun is Han, so he can't quite understand the other party's thoughts.

Another ten days passed

The buildings on the periphery are basically finished, and those that have not yet been done are at most covered with sheepskins and furs, so half of the people are collecting sheepskins and furs in the grasslands.

As for the meat that was taken off, they broke it down and hung it on a tree to dry. Or pickled.

Qian Rujun brought a lot of salt, and pickling, the delicacy of the same item, is much better than air-dried meat.

The remaining half of the people are concentrated on the central tower, and the construction skills involved are much higher, Qian Rujun doesn't plan to teach them, but he knows that if the grassland people are smart enough, in fact, if they look at it, it is estimated that they will.

This is their last chance to get in touch with advanced techniques, whether they learn it or not, it's up to them, Qian Rujun is not prepared to interfere.

In many cases, grassland people can only have one password and one action, and there is no way to do it well. These things are so unfamiliar to them that even the people who operate them may not be able to understand what they have in their hands.

However, they don't have the opportunity to practice perfectly, every time the students of the school island will always ask them to do different things, maybe only the smartest people can learn all the architectural skills, and their skills when they encounter things involve many aspects, but they don't have the opportunity to be familiar.
