The formation of the Han nationality is the result of a combination of vertical and horizontal.

In fact, the main axis of the Han nation was only a tribe after many wars, and this tribe realized that if they wanted to be strong, they only needed to defeat each other and kill each other. When their strength becomes weaker, perhaps they will be killed by others.

It occurred to them that perhaps they did not have to kill all the people, but only those who opposed them, and that the cowardly ones could be incorporated into their own tribes.

So that every time they merge a tribe, they become stronger.

This kind of thing is similar to the tribes in Borneo, or the island of Pearshape, or even countless places, except that most of the tribes still stop at killing each other, and do not accommodate the behavior of their own tribes.

The situation that Qian Rujun encountered before was that the other party began to protect other tribes, and there was an act of incorporating the tribes that collected protection money into their own territory.

And this kind of behavior may eventually develop into tribal integration, so Qian Rujun doesn't want such a thing to happen.

Of course, Qian Rujun can't just know about these things, he must tell the students of Xuetang Island, and let them pay attention to it, and plan for this situation at any time.

However, he felt that this was the most normal thing in this land, and most of the situations would happen, and it did not become anything to be noticed in the future life. At least, history proves that none of the southern tribes replaced the main ethnic group of the Han Dynasty in the end.

Most of the unification is also from the north to the south.

As for after the Tang Dynasty, whether it is considered that the Hu people unified this place, in fact, when Hu Yi entered China, he was considered Chinese.

As long as you live in the land of the Chinese, all people will slowly influence each other.

For most of history, there was no more glorious culture than the Han people in the vicinity, so it became normal for the Chinese to influence other tribes.

The other surrounding tribes, if they are to win, must absorb the culture that will best enable them to advance.

Han Chinese, in history, there are many sciences that have been abandoned by them.

Even the influence of Hu music was more prevalent than the Han Dynasty's own music.

But nothing is more important than food.

For all the tribes, what they want to learn most is also the various ways of farming.

Focus on farming, so that Dahan's farming techniques are easier to accumulate than other technologies.

In the twentieth century, a large number of Westerners tried to help Africa, but much of the agricultural technical aid failed.

In fact, many of the crops grown by Europeans in the tropics have been proven to be harmful to tropical soils.

Only the merchants of Southeast Asia were successful in their tropical cultivation industry.

The reason for their success has a very important relationship with the farming techniques of the Han people, as the Han Chinese migrated to Southeast Asia.

It can be said that if you don't take care of the land with the power of machinery, there is no one who compares to the Han people with purely human-based farming techniques.

The reason why the Han people are not as good as industrial agriculture is that of the Han people. The most important thing is that they lag behind others in agriculture, and the technical problems are very different from agriculture, but when it comes to understanding the land, no one can compare with the Han people.

In this primitive accumulation period, Qian Rujun is worried that any bit of disruption and any abnormal direction of technology transmission may change the country.

Qian Rujun didn't want her appearance to bring disaster to the Han Dynasty, so that this country that could survive would be destroyed because of her.

In fact, Qian Rujun felt that she was doing a mechanical action. If it weren't for the yellow rosewood, which was something needed for e-paper books, Qian Rujun's wood did not have special requirements.

Of course, Qian Rujun admits that rosewood is a good building material that can be kept for a longer period of time.

But Qian Rujun was in the north of the Han Dynasty and still found that many equally precious building materials had disappeared in the long river of time even earlier, and Qian Rujun knew that the better things were, the sooner they would be used. It will also be extinct sooner.

Because, people's observation, it is easy to detect the changes of these woods, and better record them.

Seeing the work in various places and slowly unfolding, Qian Rujun not only appeared from time to time to let people discover her existence, but also took the initiative to help them when they were in trouble.

She wants to be the most faithful person in this place, so although she will be stingy, she will often show up to help them when they need her most.

Then, on the land of Pear-shaped Island, more legends of Qian Rujun began to appear.

When Qian Rujun needed to leave, she specially performed that God was looking for her, so she temporarily returned to Heaven.

Then Qian Rujun naturally left secretly.

She did not take three ships. Instead, he secretly flew back to the Leizhou Peninsula.

This time, Qian Rujun flew over this land in a flying way throughout the whole process.

This is the first time she has taken a serious look at how people in this land live.

In order to be serious, her speed slowed down very low, but she had to stagger the human gaze.

If the speed is fast enough, Qian Rujun can't see the surface at the same time, the people on the surface can't see the people in the sky.

Slow down, in fact, there are a lot of troubles.

But Qian Rujun likes to find trouble.

The most important reason is that she has changed her appearance.

Qian Rujun knows that people are still animals with appearances, and he has judged and added impressions to people's appearances, so he has his way of treating them.

So, if you change your appearance, people will get to know her anew.

Whether there is a god in the Han Dynasty, Qian Rujun does not know.

But Qian Rujun knew that if he was discovered, he would be considered a god.

Qian Rujun has specially become a lot of images, and every time people find out, they change their images.

It's not that she deliberately wants to take such a risk, or rather, Qian Rujun wants to see the world with her own eyes.

If it was in the dark, Qian Rujun could only pass very quickly.

Even in the twenty-first century, there are many places in this land, where it is dark at night.

In this era, it is even more completely dark.

Jinmai City and Chang'an are the most beautiful flowers in the Han Dynasty.

At night, the splendor they exude represents that humanity is breaking through the curtain wall of this era and wants to unravel the mystery of the land in which they live.

For the most part, people are waiting to light up their civilization.

If you want to make a journey of civilization, Qian Rujun may be able to fly in the dark.

In the darkness, light and shadow can break through the darkness and reach the truth, in the same way, the light is very different in the night, and in this case, as long as you stand on the same horizon as the light, it is difficult not to see the light.

In the Han Dynasty, during the day, even if the light was dim, as long as people could see things, people would work hard.

Labor is labor and action.

When people move, a lot of danger and difficulty happens.

Although, in the dark night, they also have difficulties, but in the dark night of the Great Han, it is too difficult to find.

Qian Rujun wanted to investigate what difficulties the people of Dahan encountered.

In fact, Qian Rujun was able to summarize these difficulties into clothes and food, as well as politics and oppression.

In addition, human beings have always been the strongest animals, oppressing people and taking the fruits of other people's labor, not only can they get an extra share.

A lot of people enjoy it.

Many times, if someone wants more, it constitutes the evil of this world.

But the Han should have a unique pain that belongs to this era, a kind of pain that does not exist in other times or at other times.

Qian Rujun's flight this time wants to get rid of some unique pains that belong to this era.

This pain may belong to her alone, or to a certain group. But it doesn't belong to the whole of Dahan.

The problem of the Han group is the problem of the emperor, if you want to solve it for the emperor, the emperor will solve you first.

Qian Rujun didn't know what she wanted to do, she just wanted to study it, it stands to reason that she is already a powerful figure in this era, so what should she be able to do?

If she can't do it personally, what about adding the students of School Island?

Yes, Qian Rujun is looking for jobs for the students of Xuetang Island again.

One person's ability is limited, and if she pulls a thousand people to help people together, then the strength will be greater.

Qian Rujun knows that people will never be able to help.

But all the help, for most people, who are not particularly selfish, can bring him the fire of life.

He may not give you anything in return.

They can't afford to reciprocate either. Qian Rujun has too much, and very often, she finds that she seems to have no need for Dahan as long as others don't bother her.

Personally, she had lived to the point where she was bored, but at this time, she knew better what she had to do.

Helping people is never boring.

But repeating the same work, it will be boring.

At this time, it is appropriate to find someone else to do the work.

At least, Qian Rujun can find some people to undertake such labor for her.

Some people in Zhejiang don't necessarily need any kindness, as long as they treat these things as a job.

But in advance, Qian Rujun must go personally to see if there is anything in need of help in this world, and by the way, solve some things that need help.

Qian Rujun knew that even if she could fly in the sky, she would not be able to see the pain hidden in her heart.

But flying in the sky, she was able to see more crying people than on flat ground.

When a person cries, many times, it means that he has encountered difficulties that he cannot solve.

Qian Rujun knew that there must be someone who needed help.

As for the people who walked through the difficulties with a smile, Qian Rujun admired them, but Qian Rujun had no way to tell them that she was willing to help them.

But Qian Rujun knew that as long as she lit a fire, there must be a prairie fire burning, and the problem could not be solved until all the grass in the grassland was burned out, or someone came forward to extinguish the fire.

As for being discovered, people have a little more faith, knowing that they are afraid of being punished by the gods, and they can also reduce the suffering of some people!

At least some people found out that there really were gods, and they didn't dare to do the bad things they were supposed to do.

This is equivalent to helping many people, and it is also a merit to escape from suffering.

As for someone who began to create faith to create the suffering of faith, Qian Rujun had no choice.

Everything has two sides to the same body, and you can see how people want to use these two sides.

Qian Rujun found that things seemed to be a little more complicated than she thought.

Those who bully others do not know that they are part of the same people.

A lot of people are complicated, they bully someone and protect that person at the same time.

Qian Rujun didn't want to care about the complicated reasons at all.

But when Qian Rujun saw that many fertile plains on the land were still wasteland, she suddenly found that she had forgotten what she had discovered a long time ago, and her Jinmai City, before the construction of Shuizhen, was a wasteland full of water.

This kind of thing, the Emperor of the Han Dynasty is not impossible, Li Bing can do it, the construction of water conservancy facilities, people are not necessarily weaker than these ancients.

But to make a water conservancy project, you must have people, time, and money, at least without money, you must have food.

If an official wants to be in office for a long time, he must have an awareness, needless to say how badly you bully the people, everyone does this, but if you let the people not survive, one or two are fine, it is an accident.

But if a person under your management is starved to death because he is called to build a water conservancy, even if you complete a rare water conservancy project, your future is bound to be dark.

Qian Rujun saw the water flowing everywhere, she knew that if this water had been walking in a fixed place, people would look at the development of these green lands, but these water flows are too long to change direction, and this frequency makes people dare not take risks.

That's not a year or two, it's not two years or three years.

Rather, it is often dirouted.

In later generations, it was felt that the flow of water was basically a fixed river course and a fixed flow direction, because in the end, people had used river embankments to bind the direction of water flow, and the earth became relatively high.

However, if there is no man-made object to stop it, there will still be a big flood every two or three years, but this result is more bearable than if it happens from time to time every year.

Although every dynasty in the land of China has no money, the local officials never need the court to have money to do things, as long as there are enough gentry in that place, and the gentry have enough money in their pockets, they can use their money bags, and there are also opportunities for local people to serve in labor, and slowly repair the embankment.

And form something that can be irrigated and can bring greater benefits to the local area.

Although the imperial court has no money, the money of the imperial court alone has never been the part that these people fancy is the part they like, the part they fancy is power.

As long as the official position is promoted high enough, he will be able to expand his power and steal money from others. Especially those who can only make money, but don't know how to improve their power, this money is the real money bag of high-ranking officials in the imperial court. can let him, and his family, live a good life.

It is true that some people suffer because of this, but at the local level, a stable waterway has appeared.
