Zhang Yuan spent a lot of thought in order to get the mold of the copper coin.

Now most of the molds are copper fans, and the more rough private casting workshops use pottery fans.

When Liu Che minted his own coins, he had just used Tiefan.

Zhang Yuan, on the other hand, wanted to use the steel mold directly.

The better the quality of the mold, the higher the quality of the coin, which is a natural thing.

Zhang Yuan first had to make out the convex orthography of the mother mold, and then he could let Xiong Da and them stamping in large quantities to manufacture the real copper coin sub-mold.

According to Zhang Yuan's assumption, the font of the copper coin, as well as the hollow inside and the outermost edge, must be convex.

This allows the weight of the coin to remain the same, but thicker.

Zhang Yuan still wanted to get out the five-baht coin, which could be circulated for thousands of years, which shows its irreplaceability at this time.

In fact, it is very simple, the five baht money is the word five baht, Zhang Yuan doesn't have to think about anything.

You only need to build the mother fan at the beginning, and then hand it over to Xiong Da and them in the end.

To create the mother fan, Zhang Yuan spent three days.

When it was completed, it actually took a lot of effort.

The general appearance of the mother fan is not much different from the appearance of the last coin.

Copper coins are actually a copper-based alloy, not pure copper.

Now the process can't get pure metal, but the hardness of pure copper and the actual use of it are also more likely to corrode.

Zhang Yuan's ratio is to come directly according to the proportion of half a tael that Liu Che got before.

The square holes and round-edged fonts of copper coins are raised, and those who want to grind copper chips are easy to find.

As long as ordinary people have copper coins that meet the standards in their hands, they can see the difference when they compare them.

For those who are privately minted, he has to use copper in the end to cast money, which does not mean that he has no cost.

Unless he has copper ore in his hand, he only relies on smelting a little copper scrap to make a few copper coins, which is not as much as the income from farming.

The difficulty of grinding becomes greater, the profit decreases, and when the private caster realizes that he is not able to make a lot of profit from it, he will stop the business.

As for taking back the power of the county to mint money, that is Liu Che's business, not what Zhang Yuan needs to worry about.

The mother model was given to Xiong Da and them, and they got a large number of child molds on the same day.

Then Zhang Yuan didn't let them polish the mold, for fear that the specifications and weight of the final money would change too much.

Even though the resulting coins may look a little rougher, they are much more beautiful than the copper coins in circulation.

Zhang Yuan knew that even when Liu Che started to mint five baht coins in the end and set up Shanglin Sanguan in order to mint money, the mold used by Shanglin Sanguan was not as good as his own.

In order to make the coins look beautiful and not easy to imitate, they used extremely high-quality copper and clay molds.

Each mold is beautifully made, but the weight of the final coin fluctuates by at least 20 percent.

This is the disadvantage of not having a master mold and the mold being easily damaged.

After making the mold, Zhang Yuan asked all the copper coins in the vault to be moved to the blacksmith workshop at home.

This is just behind the bamboo forest, and there is a ditch that leads down from Lam Tin Mountain.

Here Zhang Yuan also got some horizontal wheel water drains, the effect is of course not as good as natural rivers, but the melting point of copper is low, and lead ore is added in the process, and the horizontal wheel water drain can easily increase the temperature to melt these metals.

While everyone was in full swing to mint new money, Zhang Yuan took a look at Chu Da's family by the way.

Whenever he remembered that Chu Da was still on the side of the Huns, Zhang Yuan would always be worried in his heart.

Thousands of miles away in the north, the Xiongnu in Xushan Mountain, a group of Huns are discussing whether to launch an unprecedented revenge against the Han people at the time of the handover of spring and summer.

Between the Han-Hungarian Wars, the biggest blow to the Han people by the Huns should have been the time of Emperor Wen of Han.

At that time, the Huns went south, plundered the territory of the Han Dynasty for a month, and then left.

Han Gaozu was trapped in Bai Deng, and that was just a loss of face and dignity.

During the time of Emperor Wen of the Han Dynasty, it was really a major threat to the lives of the people and the wealth of the country.

Fortunately, the Huns did not do this all the time, otherwise the people's confidence in the country is estimated to continue to decline.

A country that can't even defend its borders will definitely not have the support of the people.

The military ministers never felt that the defeat in the first two wars was really because the Huns could not defeat the Han people.

It was only forced to forcibly fight two positional battles with the Han Chinese, and such a war was originally not suitable for the way the Huns fought.

The Huns' consistent way of fighting should be to shoot a cannon and then immediately change places.

The style of frontal toughness is really not suitable for the Huns, so the military ministers want to launch an unprecedented revenge to let the world see whether the Huns are still the Huns in the past.

After two consecutive defeats, the rest of the nomads under their control were already ready to move.

Not to mention the Qiang people, who are basically their lackeys, the Qiang people's nature is easy to repeat, and the character of the grass on the wall.

This is not a threat, the biggest threat is from Xianbei and Wuhuan in the east.

The Xiongnu occupied the best pastures, leaving the mountains and mountains in the east to the Xianbei and Wuhuan people.

What are the two huge nomads entrenched in the western foothills of the Great Khing'an Mountains?

In order to one day, riding a war horse from east to west, without any obstacles, occupy the vast prairie of the south and north of the desert.

The population of the Xianbei people, the Wuhuan people and the Qiang people has surpassed the Xiongnu, and the nomads who can be put on horses to fight have always counted not the number of large armies, but the number of ethnic groups.

Can the military minister not be worried?

The position of Da Dan Yu passed from Mao Dun to him, and he could not waste all the efforts of the Huns for a hundred years.

Those three nomads had not yet provoked the Xiongnu tribes, and it was really unwise to rush into war against them.

Moreover, in the Great Khing'an Mountains and the Qinghai Plateau, the Huns may not be able to catch up with the tails of the Xianbei people, the Wuhuan people, and the Qiang people.

The Han Chinese, who stood still in the south and had dealt two blows to themselves in succession, became the only option for the military ministers.

But why didn't Junchen make a decision directly, the reason why he hesitated was that he was worried about his body.

When he goes south, if he dies on the battlefield, then what revenge is there?

The left and right Xian kings, as well as the left and right Gu Li kings, may directly start a war in front of the Han people for the position of Da Dan Yu.

Yi Zhixian has now been promoted from the king of Zuogu Li to the position of king of Zuoxian.

Yu Shan is gone, how can he tolerate others to occupy the position of Da Shan Yu at his fingertips.

The military minister thought about it for a long time, and finally decided to personally lead the army south.

The Huns worship the strong, and they must not let the people below see that they have gradually begun to weaken.

This is the truest thought in the heart of the military minister.

After making a decision, the Huns began to meet to discuss which county to attack. Twelve Literary Network

"Da Shan Yu, in my opinion, we are still attacking the newly expanded Shuofang County of the Han people.

It was originally our territory, and we can take it back this time and wash away the shame of the previous time! ”

"That's right, Da Danyu, we'll attack Shuofang County, and then we'll take all the Wuyuan County and Yunzhong County!"

The big tent was basically filled with voices that were going to attack Shuofang County.

There's no way they've suffered a lot there, and now they want to get back on the field.

But I didn't want to gnaw on the two hard bones of Surrender City and Tou Manchester City, so I chose Shuofang County instead of Wuyuan County first.

"Chu Da, what is your opinion?"

Seeing that Chu Da on the left hand side had been smiling and not speaking, the military minister frowned and asked him.

He has never been able to truly trust Chu Da in his heart, a Han man standing in the king's tent, no matter how you look at it, it is a little abrupt.

Chu Da glanced at the Huns in the account, these people are all kings and generals of the Huns, and they basically belong to the highest level of power.

However, Chu Da really didn't take them seriously, just thinking about the losses there, and not thinking about why they suffered, it seems that this is the reason why the Huns are doomed to failure.

"Da Shan Yu, I don't think I should go to Shuofang County.

Have you forgotten why we fought such an inexplicable battle with the Han people in the first place? ”

The military minister naturally will not forget that he lost his son in that battle, let his son be captured and went to the Han State, and then danced for the Emperor of the Han State, and finally after his son died, Liu Che also sent someone to collect the body and send it to the grassland.

When the military minister saw the incomparably old Yu Dan and the corpse missing an organ, the hatred in his heart could not be suppressed.

This is also the fundamental reason why he would rather risk his own death this time and must take revenge on Dahan.

"I haven't forgotten and I won't forget.

If it weren't for a high que, our 200,000 cavalry would have been able to go south directly to rescue the Aries King and the Loufu King, and it wouldn't be..."

The military minister just wanted to spit out Shan's name, but in the end he swallowed it hard.

Now the word Yu Shan has been equated with shame in everyone's eyes.

If Yu Shan died in battle, then he was a hero, but he eventually surrendered.

One misstep turns into hatred for thousands of years, no matter what nationality it is, the most disgusting thing is naturally the betrayer of its own nation.

"Since Da Danyu still remembers, he should know that we can't take advantage of anything.

The Han emperor had already begun to repair the Great Wall on Yinshan Mountain, and if we chose Shuofang County to go south, we would definitely be blocked.

The Han people north of Yinshan will hide in the surrendered city and the head of Manchester City, and the Han people on Yinshan will hide in Gaoque Fortress, as for us, will we spend a lot of time and materials to cross Yinshan? ”

The most realistic problem is in front of us, and the moat is the moat.

In some places in Yinshan, the mountains are gentle, but the first thing that Han craftsmen repaired was the Great Wall of Qin.

A Yinshan mountain range that stretches for thousands of miles, originally a mountain range that fed the Huns, provided a large amount of prey and fruits for the Huns.

Now it has become the biggest obstacle for them to go south.

"Chu Da is right, we want to attack the Han people as quickly as possible this time, and we must not spend too long climbing over the Yin Mountain.

Shuofang County, Wuyuan County, Yunzhong County, and Dingxiang County were not suitable targets for this attack.

Let's talk about which place we should attack. ”

"Yuyang County!"

Before the others could open their mouths, Chu Da shouted loudly.

"Tell me why you want to attack Yuyang County?"

The military minister still wants to hear what Chu Da's reason is, which is also more convenient for him to analyze whether Chu Da is really taking refuge in himself.

"Da Shan Yu, do you know who the Taishou of Yuyang County is?"

"Han Anguo!"

In the list of border county guards, the only thing that the military ministers can remember is Han Anguo's name.

As soon as Chu Da asked, the military minister had already made up his mind to attack Yuyang County.

"Han Anguo used to be the imperial historian of the Han Dynasty, and although he is now demoted, the emperor of the Han State still attaches great importance to him.

When I was in Chang'an City, Hou Tian Wei of Wu'an of the Han State stepped down from the position of prime minister, and the emperor of the Han State thought about letting Han Anguo take over.

In addition, Han Anguo originally had a blood feud with Da Danyu, and our Huns were more familiar with Yuyang County.

The choice of Yuyang County for this retaliation is the most correct choice. ”

No one cared about what Chu Da said about us Xiongnu, and they all began to consider whether choosing Yuyang County was the best choice.

The military minister did not hesitate and directly affirmed Chu Da's suggestion this time.

"Ladies and gentlemen, gather 100,000 cavalry and baggage at once.

This time, we are going to attack Yuyang County, so that Yuyang County in the Han Kingdom will not grow a single inch of grass and be deserted! ”

"Yes!"

Chu Da This is not an act of treason.

The Huns were already destined to choose a large Han border county as the target of attack.

No matter which county to attack, it will be a great loss for the Great Han.

The military minister still had to ask Chu Da's opinion at this time, if Chu Da didn't say it, then his intention to join the Huns would be obvious.

If you only analyze it superficially, you will not be able to gain the trust of the military ministers.

Since the war will definitely be fought, it is important to fight there.

Chu Da didn't know much about Zhang Yuan, but he knew that Han Anguo and Chu Da had a grudge.

So since he had to choose one, he directly chose Yuyang County, where Han Anguo was the Taishou.

Moreover, he had to persuade the military ministers to attack Yuyang County with an extremely strong attitude, so that the military ministers would feel that Chu Da really hated the Han.

Zhang Yuan, who was amusing Chu Da's son thousands of miles away, did not realize that there would be a large-scale retaliation by the Xiongnu next.

The Huns have to invade the borders of the Han every year, and if it happens this time, it will be on a larger scale.

The military ministers themselves characterized this retaliation as an action, otherwise they would not have sent only 100,000 troops.

The number of people has been reduced, just to be able to narrow down their goals, and then quickly and accurately retaliate against the big man.

As for the siege, that is non-existent.

The Huns did not have siege tools, and if they wanted to attack the city, they could only temporarily build ladders and then fill them with human lives.

From the time of Maudun, the Huns knew that they would not occupy this large area of land to the south, and they considered themselves to be a nomadic people.

If the nomads wanted to occupy the territory of the Han Dynasty, they were destined to be gradually assimilated by the Han people in the process.
