Leaving Lubanyuan and sitting in the carriage back to Chang'an City, Liu Ying couldn't help but think to herself.

More than three years ago, with the battle of 'Annihilating and Defending Korea', which can be called an armed parade, Liu Ying made a preliminary martial arts and initially accumulated his prestige.

But whether it is Liu Ying, who is the Son of Heaven, or the ministers and officials of the court, and even the common people, they all understand very clearly: for the emperor of the Han Dynasty, there is only one result worthy of being called 'martial arts'.

- Chase the Huns in the north!

In the original history, from Emperor Taizu Gao Liu Bang, to Emperor Taizong Xiaowen Emperor Liu Heng, and then to Xiaojing Liu Qi and Xiaowu Liu Che;

The kings of the Han family have all had the idea of going north to chase Hu.

For example, Liu Bang, Emperor Taizu Gao, proved that the charioteers must be eliminated with a very insulting siege of Baideng!

And the later Taizong Xiaowen Emperor Liu Heng, with that preparation for many years, smashed countless money and grain, but in the end could only compromise and make peace with the Huns, so as to turn back and extinguish the rebellion of the princes of the clan 'Jibei King Liu Xingju Rebellion', which proved that if the Han family wants to fight outside, it must first settle inside;

So later, as soon as Emperor Jing Liu Qicai ascended the throne, he couldn't wait to start cutting the feudal domain, and even did not hesitate to completely detonate the contradiction between the central Chang'an and the Kwantung clan princes.

Later, after more than 50 years of 'recuperation' and 'internal integration' of the fifteenth year of Empress Dowager Lu, the twenty-fourth year of Emperor Xiaowen, and the sixteenth year of Emperor Xiaojing, the Han family was finally able to complete the historical mission of chasing the Xiongnu in the north in the hands of Liu Che, Emperor Xiaowu of Han Shizong.

And now, the same problem is in front of Liu Ying.

——Is it the same as in history, Empress Lu, who was willing to be a green leaf, and the two emperors Wen and Jing, who endured humiliation and recuperation, and accumulated enough wealth for future generations to defeat the Huns?

Or fight for the national fortune, do it hard, and eradicate external hidden dangers for future generations?

Liu Ying has also thought about this question for a long time.

Everyone in the world knows that the First Emperor swept the Six Kingdoms and unified the world, but he always ignores the First Emperor's reign, and often hangs on his lips the sentence 'Qin Fen VI';

Everyone in the world knows that Han Wu chased the Xiongnu in the north and revitalized Liu Han, but he will always say the last sentence ridiculously: Wenjingzhizhi is a hammer, either amicable or soft, Emperor Wu is the first emperor through the ages!

But even so, it is still indelible in history, the great contributions to Chinese civilization made by generations of Chinese emperors who were willing to be green leaves, and even willing to bear the scolding of future generations, and also to lay the foundation for future generations.

Especially the five Qin kings before Qin Shi Huang, as well as the founding emperor and the second emperor Wenjing before Liu Che, Emperor Wu of the Han Dynasty.

Liu Ying also thought about whether to spend his life building the Han dynasty into an incomparably powerful centralized government and laying an incomparably solid foundation for future generations.

But soon, Liu Ying dismissed her idea.

Because after a short period of investigation and research, Liu Ying found that the reason why the Han family in history had to endure the humiliation of nearly a hundred years from the first battle of Taizu Gao Emperor Liu Bang Baideng to the Wu Emperor Liu Che sending Wei Huo to the north was simply because of the development model of the Han family.

——In history, from Taizu Liu Bang to filial piety Liu Ying;

from the former less Liu Gong to the later less Liu Hong;

and then to Emperor Wen Liu Heng and Emperor Jing Liu Qi, what the Han family has always implemented is a 'province' formula.

The treasury relies on agricultural taxes to support the operation of the court, and the small treasury is saved to the maximum extent;

It was only after Emperor Wu ascended the throne that the Han family was able to save enough money, food, and horses to support three to five decisive battles with the Huns!

But as a descendant, Liu Ying knows very clearly: money is not saved, but earned.

Especially now, when even the feudal social system has not yet been perfected, and all the ideas of 'deviance' have not yet been hindered by the 'ancestral system', the powerful feudal emperors do not have too many ways to make money.

It is said that in the years before and after Liu Ying's accession to the throne, the Shaofu relied on the income of the people's grain storage and official grain and rice, which was enough to match the achievements of the three generations of kings in the original history, filial piety, former youth, and later youth, and as long as fifteen years before and after!

As for the salt and iron, which rose later and gradually showed their power, it made the central financial level of the Han family reach the middle and late stages of Emperor Wen in the original history in just six years after Liu Ying ascended the throne!

In the annals of later generations, the description of the rule of Wenjing is: the people live and work in peace and contentment, the countryside pheasants and dogs smell each other, and the people do not interact with each other until they are old and die;

Men have farming, women have weaving, the young have support, the old have dependence, the hungry have rice and hunger, and the cold have cloth for clothing;

The treasury is overflowing: the new rice has not entered the warehouse, and the old rice is poured into the water; The rope of money is broken every time; All kinds of things are piled up like a mountain, and the head is raised and the top is not visible, and the height is not visible.

Compared with the rule of Wenjing in history, what kind of picture is the Han family today?

- The people are not suffering from hunger and cold, Liu Ying does not dare to say that it has been completely achieved, but at least within the scope of Guanzhong, the people 'do not have to sell the harm of grain price fluctuations', but it has long been a reality;

The treasury is so full that the grain storage is rotten and the rope that strings money is festering, and Liu Ying doesn't dare to guarantee it, but at least when there is a need, Liu Ying can take out tens of millions of stone grains and hundreds of thousands of copper coins with his eyes closed, and say easily: It's okay, it's a small meaning.

If you have to say that there is any other place, it is definitely not comparable to the rule of Wenjing in history, that is, due to time reasons, the Han family does not have as many as seventy-two horse gardens and tens of millions of war horse reserves.

However, compared with the 'saving money' model that was implemented from the early Han Dynasty to the period of Emperor Wu of the Han Dynasty in history, today's Han family, under the leadership of Liu Ying, has a complete set of stable and long-term profit models.

In the future that can be seen with the naked eye, the governance of Wenjing in history will inevitably become the 'rule of filial piety' in this timeline where Liu Ying is located.

In this case, why did Liu Ying have to adopt a conservative 'boring development to fight the later stage', instead of taking advantage of the fact that the Huns had not yet completely unified the grassland, and eliminated the threat from the northern grassland in one fell swoop?

After thinking about this, the Military Industry Department established by Shaofu by order also came into being.

- If you want to defeat the Huns, the only thing Liu Ying can create an advantage for the current Han family is logistics!

To be more specific, it is an adequate food supply, a perfect pension system, and weapons and equipment that are ahead of the times.

Therefore, Liu Ying's official grain and rice camp have increased the army's pension strength several times;

Therefore, the Shaofu Military Industry Department was formally established three years ago, and became the only subordinate department of Jiuqing that has reached the level of more than 2,000 stones, except for lieutenants and lieutenant generals.

At the beginning, Liu Ying also naively thought: as long as countless resources are thrown into it, then even if there is no 'traverser' to open a plug-in, with such a huge R&D resources, the Department of Military Industry will inevitably make something;

But soon, Liu Ying found out: she was wrong.

The limitations of the times and the limitations of thinking are almost infinitely magnified in the military industry, an industry related to the fate of civilization;

Liu Ying's first investment in the military industry department only received a batch of more well-made old weapons that were no different from the past, such as ge, spears, swords, halberds, and bows and crossbows that were not much different from the past.

The only unexpected gain is that the craftsmen of the Military Industry Department borrowed the records left by the Qin period to recreate the black technology that once dominated the Central Plains in the Qin period: the bronze hand crossbow.

Nothing else.

Realizing this, Liu Ying did not hesitate any longer, and almost immediately fired on the firepower;

Scale armor, plate armor, Mo knife, divine arm crossbow, all the weapons and equipment that appeared after Liu Han in Liu Ying's impression were put on the agenda by the Shaofu Military Industry Department.

The urgent need for forging steel technology was also placed in front of Liu Ying after the research and development of this series of new equipment began.

After that, Liu Ying did research again;

It's just that the conclusions reached are not satisfactory.

Nowadays, although the Han Dynasty has stepped into the Iron Age with one foot, let alone steelmaking, even iron-smelting technology is still in a very backward initial stage.

Compared with the bronze smelting technology that reached the peak level hundreds of years after the Spring and Autumn Period and the Warring States Period, the iron-smelting technology mastered by the Han family today is like a child pinching mud.

In the vast majority of cases, the performance of the iron tools that appear at this point in time is completely destroyed by the same type of bronze products!

Corresponding to the backward smelting process is the outrageously low output of iron: not counting Shaofu, it is only 200,000 catties a year in the whole world;

It is only fifty tons in later generations, and it is piled together, that is, a piece of iron billet with a length and width of one zhang and a height of more than half a zhang······

Iron is like this, and steel is even more needless to mention.

——Nowadays, the Han Dynasty, the only mature steelmaking process mastered is the frying method;

According to the description of Shaofu Yang Chengyan, a skilled steelmaker can fry hundreds of catties of steel a year;

But there are only a dozen craftsmen of this level.

Before the layout of Shaofu along the way, the annual output of steel and iron in the entire Shaofu was only 2,000 catties of steel and more than 50,000 catties of iron.

Two thousand catties of steel, what is enough?

- You can make thirty cuirasses that meet Liu Ying's requirements, or forty Mo knives of acceptable quality.

one year;

This is Shaofu's steel production in a year.

Obviously, what Liu Ying wanted was not an escort team of dozens or hundreds of people, but an elite field force composed of thousands of people;

And such a field force, especially a new-style heavy infantry unit with Mo knife and plate armor/scale armor as weapons and equipment, is definitely not something that Shaofu can complete the supply of weapons and equipment by relying on an annual steel output of 2,000 catties······

"To fight the Huns, since there are no horses, then you can only work weapons."

"Especially iron and even steel weapons, in order to occupy a cross-era advantage in front of the bronze weapons of the Huns."

"Alas······"

"100 Steel ·········"

With a gloomy expression, Liu Ying couldn't help but feel a touch of regret on her brows.

Liu Ying knows that the biggest difference between steel and iron is that iron is an iron element; Steel, on the other hand, is a synthetic metal, which is often referred to as an alloy in later generations.

The best way to turn iron into steel is to use iron as the main raw material to support the hardness of the steel, and then add other metals to provide toughness.

To put it more bluntly, it is through the mixing and melting of two or more metals to make the alloy have the advantages of a variety of metals.

However, in today's Han Dynasty, iron is made into steel, but it can only be forged to fuse iron and carbon to form an 'iron-carbon alloy', which is the carbon steel in later generations.

Compared with other types of alloy steel, carbon steel obviously has shortcomings such as too single performance, not good enough, and complex production in the current era;

But at this stage, Liu Ying can only retreat like this······

"Let's leave it at that."

"Let's get the carbon steel out first, and form a new army;"

"Later, we can make high-carbon steel, medium-carbon steel, and low-carbon steel respectively, and then consider more complex alloys."

Thinking so, Liu Ying shook her head implicitly, and then focused her attention on the bamboo slip in front of her.

This bamboo slip is the hand-copied version of the Xiongnu letter sent to Chang'an some time ago.

In this letter of state, Liu Ying only felt scorned at the unsubtle request of the Xiongnu Shan Yu Maodun, or to order the Han family to abolish Andong County and flow out of the 'strategic easing zone' for both sides.

In the past so many years, the Han and Hungarian sides have long known each other well!

Let's just say that now, the Han family has set up Andong County on the Korean Peninsula, which seems to be directly bordering the Xiongnu's sphere of influence from the map;

But in fact, if you find out what area of the Xiongnu is north of Andong, it is not difficult to find that the 'strategic détente zone' in Mao Dun's mouth is simply something to coax three-year-old children to play!

——To the north of Andong, or to the northwest, are the Xianbei and Wuheng mountains in the territory of the Xiongnu!

These two mountains were used by the Huns as exiled prisoners!

At the moment, the two slave tribes that once belonged to the overlord of the steppe: Donghu were felt by the Huns, and named these two mountains respectively: Xianbei Department and Wuheng Department.

Such a 'bitter cold place' used to exile prisoners needs to set up a 'strategic détente zone'?

Joke!

——Own Han, even Ji Zhou, the grassland people went south to the Central Plains, that time was not a breakthrough from the generation?

Not to mention the Xiongnu Far East where Xianbei and Wuheng are located, even the eastern half of the border of Yan State, such as the right and north equal directions, are rarely chosen by nomads as a breakthrough point for southward plunder.

So, Liu Ying decided······

"Since you want a 'strategic détente zone', don't say anything about Anton;"

"Wouldn't it be nice to just empty the loop?"

Thinking like this, Liu Ying also made up her mind and began to raise a letter of state for Mao Dun in her heart.

The Hetao area is the pearl of the grassland, and at the same time, it is also an indispensable horse breeding ground for the Chinese nation;

In order to completely eradicate the external threat of the 'Xiongnu' in their lifetime, the Han family needed such a piece of horse breeding land to provide a steady stream of war horses for the cavalry troops.

At present, in terms of the strength of the Han and Hungarian sides, the Han family still needs to make a lot of efforts to recapture the Hetao.

To be precise: there are many things that Liu Ying needs to do······
