However, the value of this Zhuo Wang Sun is not only this.

In Zhuo's hands, there is almost the most advanced ironmaking technology in this era.

Compared with bronze and iron, it is still very inferior.

However, in comparison, bronze weapons are harder than iron weapons, but there is also a fatal flaw, that is, bronze weapons are relatively brittle, and when two weapons collide violently with each other, they are easily damaged. Iron weapons are tough, not easy to break, can be well adapted to the fierce war, iron swords can often cut bronze weapons, so it is inevitable that bronze weapons will be replaced by iron weapons.

In this case, whoever masters the iron has the ability to wage war!

However, bronze ware also has its merits, but in terms of ritual ware, it is irreplaceable.

From ancient times to the present, in the history of China, as long as it is an important time, most of the important ritual vessels are cast in bronze.

Simu Wuding, and the god that has already been passed on, the nine tripods cast by Dayu, which is not cast in bronze.

And copper can also make money, this coinage, it can only be minted in copper, copper money can be said to run through the entire history of China, whether in the era of slavery, or in the era of feudal monarchy, are useful.

However, on the other hand, only by constantly strengthening the country's iron-smelting capacity can we achieve victory in future wars, and the Huns are not good at ore mining, let alone smelting.

However, the Han family has a strict border trade system, and no one is allowed to carry weapons and go away, except for those sent by the Han court, of course.

But the Huns are not stupid, of course, their favorite is looting, since I don't have it, then I will rob yours, grab your things, then I just have it.

In the course of the Han-Hun confrontation, the Huns plundered the border of the Han Dynasty many times, and naturally they also plundered many people from the Han Dynasty.

And among them, there are naturally some iron-smelting craftsmen, and it is in their hands that the Huns have obtained iron-smelting technology.

However, after that, the Han Dynasty appeared a technology called frying steel, and in the ancient world, I was the first country in the world to have a method of frying steel: cast iron decarburized steel. It is annealing and decarburizing iron castings to make them steel. Depending on the application, it can be properly mastered during annealing to obtain high-carbon steel and even low-carbon steel with different carbon contents, which is a convenient way to turn iron into steel.

In the Sanskrit of the third brother, there is a word "Cinaja", which reflects the impact of Huaxia Iron and Steel on the third brother, no, the current body poison.

In the first century A.D., the Roman naturalist Pliny said in his famous book: "Although there are many kinds of iron, none of them can compare with the beauty of steel from China." ”

Even the form of many swords of the Xiongnu is very similar to that of the Western Han Dynasty, which shows that the Xiongnu not only could not keep up with the materials, but also the design.

In a word, you take iron and steel to touch, of course, iron will be cut in two sections.

However, Li Ling, who was unlucky, was able to fight against 110,000 Xiongnu with 5,000 infantry, and fought for so long, and finally ran out of some Han troops, about 400 people. However, a large part of the reason why it can do this is that it takes advantage of weapons.

…………………………………………………………………………

At this time, the person in front of Liu Rong is in his hands to master the technology of smelting iron and forging steel, such a good opportunity is in front of him, of course Liu Rong must grasp it.

And Liu Rong heard that this Zhuo Wangsun, after the fall of Deng Tong, got several copper mines of Deng Tong and used them to make money.

In this regard, Zhuo Wangsun, a merchant with an extremely low status, can be said to hold copper ore in his left hand to mint money, and his right hand to pinch the art of smelting iron and steel.

Of course, even if he didn't come here to see him today, Liu Rong would find a rich businessman like Zhuo Wangsun.

The things in their hands are now exactly what the Han court needs, and the Han family cannot allow these things to be in the hands of merchants.

Only by keeping it firmly in the hands of the imperial court.

And at this time, the Han family could not allow merchants and commerce to develop like wild horses like this.

At the time of the bourgeois revolution in Europa, the once invincible emperor was finally guillotined.

However, in the Han Dynasty, industry and commerce, of course, could not be found to such a extent, but in this era of extremely backward productive forces, if commerce continued to develop, it would certainly threaten the rule of the imperial power............

However, a giant businessman like Zhuo Wangsun was able to rise and swell to this point in the imperial era, and his food, clothing, housing and transportation were comparable to those of a human king.

The livelihood he did must be a livelihood outside the laws of the Han family.

For example, if you sell foreign slaves and sell the silk and other goods of the Han family to other countries, it will definitely do something.

Then Liu Rong said: "Mr. Zhuo is a well-known rich businessman in the world."

Hearing this, Zhuo Wangsun immediately smiled, and saluted: "Xiaomin is just a cheap businessman, how can His Highness say so."

Seeing this, Liu Rong secretly said in his heart: Just a cheap businessman, Liu Rong doesn't believe it at all..................

Then Liu Rong and Liu Rong asked: "I heard that Mr. Zhuo had a relationship with Yidi in the southwest, and I don't know if I can know something about Yidi in the southwest."

Zhuo Wangsun didn't expect that Liu Rong came up to ask such a fatal question.

The Han family has some strict management systems, only the imperial court can intersect with foreign countries, and the rest of the people are not allowed to intersect with foreign countries privately, which is a capital crime of extermination.

The attitudes of all dynasties towards this kind of thing are actually about the same.

Even the Tang Dynasty, which claimed to be the most open and inclusive, was also inadmissible for non-governmental acts to engage with foreign lands.

Xuanzang went to Tianzhu to learn scriptures, but he was not really sent out by Li Er in person as in Journey to the West.

Instead, he went to the border and smuggled away.

…………………………………………………………………………

Solid this, of course, Zhuo Wangsun knows what to say and what not to say.

Of course, it is impossible to tell the truth.

When even he bowed with his body, he said: "Back to His Royal Highness the Prince, Xiaomin has always been from the laws of my Han family, and he has never dared to violate anything. ”。

In this way, Liu Rong felt that in the mouth of this Zhuo Wangsun, he really couldn't hear a word of truth.

Then, Liu Rong smiled, "What Mr. said, Lone Ke disagreed, Lone Ke once saw King Yelang present the song to the Son of Heaven, in this note, but I have mentioned Mr. Zhuo's business, but I didn't do it all to Yelang Country."

Hearing Liu Rong's words, King Zhuo almost fainted, and King Yelang actually talked about himself in the letter of state presented to the Son of Heaven of the Han family.

Of course, what Liu Rong said was untrue, the book of the Kingdom of the Yelang King, Liu Rong had seen it in Tianlu Pavilion.

It only said that he hoped that the emperor of the Han family would give him silk brocade, tea and other things.

However, the barbarian country of Yelang Country, although it is not far from the Han family, but it actually asked the emperor of the Han family for Shu brocade.

The preciousness of Shu brocade is rarely used even by Liu Rong, the prince, Liu Rong's father, except for the court clothes, the rest of the clothes are just ordinary silk and silk.

At the beginning, Liu Rong saw the clothes made of Shu brocade that Chen Ajiao was wearing, and he was a little "envious".

Even the Huns never got Shu brocade from the Han Dynasty.

However, the king of Yelang turned out to be bluntly asking, this does not need to be thought, it can be known that someone must have brought Shu brocade and other things to Yelang country.

And Yelang is adjacent to Shu County, and in the entire Shu County, there is no one else who can have this ability except Zhuo Wang Sun Dang.

Therefore, Liu Rong said this in order to pry open Zhuo Wangsun's mouth and learn some news about the southwest barbarians from his mouth.

From the change in Zhuo Wangsun's expression, Liu Rong found that what he guessed was indeed correct.

Then, Zhuo Wangsun had to talk about something.

And from his mouth, Liu Rong knew that the businessmen of the Han family had already been so bold.

He has repeatedly exchanged silk, tea and other goods for slaves in the southwestern countries for mining and salt production.

The Han family had slaves in the family, but they needed to pay a very heavy tax to the imperial court every year, according to the normal tax, only one slave had to pay a tax of 600 yuan a year.

However, if you buy a slave from outside the territory and smuggle it into the Han realm, then the slave can be used privately to avoid taxes.

However, the fate of these slaves is much worse than that of the slaves registered in the Han family, and as slaves, they still have some human rights.

And these slaves, on the way to the Han realm, there is a lot of loss, but their only value is to use their labor, if they are seriously ill, or for some reason unable to work, they will be ruthlessly abandoned.

According to him, this is no different from the triangular trade of blacks in the eighteenth century.

Of course, it took a lot of effort to get these slaves from the barbarian land to the Han Dynasty, because it was cheaper to use these slaves, and if they died, they could be buried directly on the spot, and they didn't have to worry about it at all.

It seems that the time has indeed come to take action to rectify these businessmen, and if this continues, something big will happen.

…………………………………………………………………………

And Liu Rong wanted to know something about the Southwest Yidi, of course, he also considered that in the Qin Dynasty, the Southwest Yidi countries were also ruled by the Qin Dynasty, and like Nanyue and the peninsula, they were also independent again when the Han family arrived.

However, these places, of course, still have to return to the arms of the Han family.

However, Liu Rong talked with Zhuo Wangsun, of course, not to investigate Zhuo Wangsun's human trafficking, but to learn more about the southwest from his mouth.

However, the most important thing, of course, is also to want to take all the iron ore and workshops of the Zhuo family into the ownership of the imperial court.

However, the largest iron producer in the world of the Han family is, of course, Shaofu, but this is only on the surface, and the iron produced by a family like the Zhuo family in a year should not be underestimated.

When he left, Liu Rong began to think about things such as returning the right to mint coins to the imperial court, and it was necessary to prepare for implementation in advance.
