Qian Rujun looked at the newly made nautical chart and thought hard. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Even though she had sent the people of Jinmaicheng to listen hard, the chart was still not satisfactory.

First, there is the issue of measurement.

In terms of small-scale measurement, most craftsmen have no problem, but for large-scale measurement, it is estimated that only the military has developed a little method.

And the methods developed by the military, if they are not passed on, may be lost. Then it all starts all over again.

In this day and age, military personnel are the most likely lives to disappear.

Because their lives, in the eyes of those in high positions, are often only a few taels of silver.

In many cases, their families are too small to receive the money.

Fortunately, the officers of the Han Dynasty were not as corrupt as the Ming and Qing dynasties in later generations. And because it is not so corrupt, the combat effectiveness of the army is still relatively strong.

If the combat effectiveness of horses is not counted, with the combat effectiveness of individuals, one point and three Han people can be equal to one Hun person.

You must know that there were not many people in the army of the Huns.

In ancient times, there was a saying that was handed down, the Huns were less than 10,000, and they were invincible.

In fact, under the horse, the Huns were not so terrible.

However, they have powerful war machines and horses.

And their horses, able to adapt to the battlefield.

Unlike the horses of the big men, they can only pull the carriage, and when they encounter a battle, they can run faster than anyone else.

The emperor saw this, and so did the officials of the court.

No one is stupid, but no one can do anything.

First, the Huns were very strict with horses. It's not easy to import.

Just like the Han Dynasty, he also controlled the iron tools very strictly, and it was not easy for the Huns to get them.

During this period, the iron training technology of the Xiongnu was far inferior to that of the Han people.

After all, the Great Han was only in the era of the development of ironware. I am not mature, and I am still improving rapidly.

Under the blockade of layers, it was still difficult for the Huns to break through the cultural barriers and obtain the method of iron training.

Very far, the Huns have improved in iron training, but the blacksmiths in the Great Wall have made even more progress.

In fact, if it weren't for the blacksmith's deliberate concealment of technology, five hundred years of technological progress would have been achieved in five years for the Han people.

You can see how much time Dahan wasted.

And how many technologies have finally disappeared without being made public.

So the West will develop patented technology, and as long as you use its technology, you will give him money.

Therefore, the owner of the technology is not afraid that people will know his technology.

In the case where most of the technology can be made public, the progress of science and technology is like flying.

However, new problems have arisen since then.

It is the emergence of technical barriers.

Too much technology has to be given money, which leads to the development of technology later is not easy.

The products that people consume are also becoming more and more expensive.

Because the products they consume have to give people technology royalties.

Everybody shares a little bit, and at the end of the day it's a little bigger.

However, the advantage of iron tools is not like the later development of gunpowder, which can cross distances and knock down the horse nation.

No matter how good the iron weapon is, only the individual's combat ability can be improved.

When will this combat capability be used?

Perhaps only when the horse's skill slowed down, or perhaps the Huns' riders were thrown off their horses.

Therefore, although the iron tools of the Han Dynasty developed earlier than the Xiongnu, many inventions were able to surpass the Xiongnu.

But it's not as good as a car that can hit people.

What would be the result of taking a sword and swinging it at a mortal who was driving?

If the opponent's car skills are a little better, you don't have any luck hitting the opponent.

Fortunately, this question does not need Qian Rujun to think about.

If it were her, she wouldn't raise any horses, but asked those Shaofu people who invented bicycles to use more effort and invent a high-speed rail that can be 400 kilometers long.

Use the carriage of the high-speed rail to hit the Huns from beginning to end, and the other party only has the possibility of turning into flesh and blood.

Even gunpowder didn't have to be invented.

In the era when there was no gunpowder, in fact, it was possible to compare speed with pure speed.

It doesn't feel that bloody either.

Qian Rujun didn't have a good impression of gunpowder.

Although a car can also knock people flat.

But after all, it's a thing in life, and she is still more able to pull it.

The route can't be the same as last time.

Something like a thousand-year-old ginseng can't reappear in a year.

Even in space, it takes a hundred years.

With Qian Rujun's thinking, she will have to report to the coffin for a hundred years, and what kind of seed will she plant.

Where you have dug up, the likelihood of digging again is relatively low. In the case of a large number of thousand-year-old ginseng in other places, it is not worth the effort.

Looking at the map, Qian Rujun's eyes crossed the Great Wall and looked at Fuyu in the north of Youzhou.

That is, the area of Changbai Mountain in later generations.

In fact, there is no need to walk through the Great Wall, in fact, North Korea can take a boat directly to Jinmai, and then from Jinmai to Chang'an.

It's just that the envoys of the countries of the Korean Peninsula have always taken this route of the Liaoxi Corridor, that is, they have to pass through the Great Wall and pass through Yanshan.

In fact, Qian Rujun felt quite stupid.

How close it is by boat!

At the current walking speed, you can save at least three-quarters of your time.

Qian Rujun knew why they didn't take the boat.

In the absence of a sturdy boat, going to sea is an extremely risky venture.

There is a 99.9999 percent chance that the ship will disintegrate at sea.

Of course, if they can get the official ship of the Han Dynasty, the craftsmen of the Shaofu of the Han Dynasty represent the highest level of the Han Dynasty.

Joseon, a shipbuilding tycoon who can easily kill later generations, may be called Mahan or Benhan at this time. Or Anonymous.

At this time, Korea was not unified in the whole territory, and even in most places outside the city, there were many wild people who carried out activities.

Especially in the mountains and forests, it is a separate work. They also don't have much sense of nationhood.

The formation of the country is the same as that of the Spring and Autumn Period and the Warring States Period. It's a bit feudal.

And where there is no feudalism, it naturally does not belong to the territory of North Korea.

Qian Rujun was thinking, should I go to my husband?

In fact, Fuyu, a foreign race, is not mentioned much in history, and it is almost mentioned in passing.

I heard that the vicinity of Licheng used to be a country called Guzhu, and it has been a country for thousands of years. However, the inverted frieze had to encounter the expanding Qi State and was destroyed.

Later, this place was taken by Yan Guo.

The grievances and grievances of the Qi State and the Yan State have also been said a lot in history.

It's just that the names of these countries have been lost to history.

Only those who are particularly interested in historical texts will know the names of these countries, and the general public is not interested in knowing them at all.

Even though the history of the Yan Kingdom is not too long, the Yan Kingdom and the nearby Qi State have also destroyed several countries in the past. These countries are almost not in memory.

In fact, not only some small countries in the vicinity, how many countries were there on the land of China in the past?

After the names of these countries were destroyed, they were rarely mentioned in the canonical history.
