"This is……"

Liu Xuan immediately understood what the cauldron was used for. To put it bluntly, it was the same principle as the quiver, except that the quiver came out with arrows for crossbows, while the cauldron came out with coins.

I took a copper coin from the hand of the historian. Different from the square-hole coins that were originally popular, although the coins coming out of the tripod were still round, they did not have a square hole in the middle.

Since the Qin Dynasty unified the world, it has abolished all kinds of complicated currencies and unified the currency system. Square hole coins have officially become the most important currency in this land.

Although the Han Dynasty overthrew the Qin Dynasty, it also inherited a lot of things - the official system basically followed the Qin Dynasty system, and then made appropriate changes. There were no major changes overall.

It was not until Liu Xuan upgraded the status of Shangshu, determined the Six Ministries to be the main political affairs processing agency of the court, and lowered the status of Jiuqing that there was a big difference with the Qin Dynasty.

Coins have also been inherited. Square-hole coins were also the main currency in circulation in the Han Dynasty, but this history seems to end here.

He turned the coin over in his hand several times and looked at it carefully - he found that there were no patterns on both sides of the coin, only words. Liu Xuan glanced at it casually and stopped looking at it.

Because the historian casually took out another piece of silver ore and threw it into the cauldron.

Then he took out a small handful of silver coins as before. They looked basically the same as the copper coins, but had different colors because of the different materials.

Then Liu Xuan didn't need to look at it. It seemed that this tripod could make three kinds of currency: gold, silver and copper. But what he was really worried about about the implementation of currency was not the casting, but the counterfeit currency. Xun You should know this.

"However, Gongda is not the kind of person who messes around. Since he proposed to let the Weapon Refining Department make this tripod, he must have some ideas, right?"

With this thought in his mind, Liu Xuan asked the Taoist Taoist beside him: "What is the difference between the coins made from this tripod and the coins made from ordinary coins?"

If Xun You thought of a solution, he would definitely tell Shi Daoren and ask him to take this into consideration when making it.

I only heard Shi Dao Ren say: "Xun Shangshu made a request at the beginning, and it is precisely because of this that making this tripod is a little more troublesome."

"oh?"

Liu Xuan was a little surprised. It turned out that there was something else in the cauldron? He really didn't check it carefully just now, but he didn't need to look at it now. He just let Shi Daoren explain it.

Shi Daoren took out two coins, one silver coin and one copper coin. He held the two coins with both hands and then knocked the two coins against each other in front of Liu Xuan.

There was no sound. Even if these two such small pieces of metal hit each other, what kind of sound would they make? But what happened next still surprised everyone present...

Although Li Su had seen it before, he still found it magical. He stared at it while sighing at the wonder of this magic.

Liu Xuan's eyes lit up, and he suddenly understood Xun You's thoughts.

It turned out that after the two coins collided with each other, they actually emitted soft light. The light was not dazzling, but it was very clear. Even in the daytime, you could see that the coins were shining.

The light emitted is generally the same as the color of its own material, and then the light will slowly fade until it disappears. However, as long as the Shi Taoist knocks the coin harder, the light will emit again.

Liu Xuan even excitedly patted the table next to him: "This is a good idea!"

After he fully understood Xun You's thoughts, he couldn't help but marvel at Xun You's intelligence. This method is very simple, and more importantly, almost anyone can tell the authenticity of coins anywhere and at any place.

This method is actually not difficult. It is to add an extra process to the tripod. When Baoding makes coins, it adds a magic circle to each coin. It is also because of this that the coins are not cast in a round outer shape and a square inner shape.

.

This array is not complicated, and in most cases it can even be said to have no effect at all. The only effect of this array is to convert the impact force into bright light when it is impacted - the stronger the impact force, the greater the light converted.

powerful.

Such a simple method can directly distinguish genuine coins from counterfeit coins. This is much more convenient than Liu Xuan's original idea of ​​adding a magic circle to the coins and then using a specific facility (banknote detector?) to determine the authenticity.

Much.

The real difficulty in implementing Liu Xuan's idea is that banknote detectors cannot be widely used. Ordinary people cannot immediately tell whether the currency they hold is genuine or fake, so counterfeit currency still has room to survive.

But Xun You's method allows everyone who gets the coins to immediately determine whether they are holding real coins or fake coins. More importantly, this technology is only mastered by Liu Xuan - he does not believe those who have the cultivation level.

Guys would mint fake coins for fun.

Even those guys in Nanhua who want to go against themselves cannot put their minds on this, because there is no such thing as economic war in this era.

In short, Xun You's method solved the hidden danger of counterfeit coins, so we can try to issue new coins this year. They were also circulated near Chang'an, and then slowly radiated to the entire Yongzhou, and finally spread to Liangzhou.

As for Sizhou, there are some remaining issues that need to be dealt with first. There is no need to worry about the currency issue yet.

"very good!"

Reaching out and playing with two coins, Liu Xuan was happy that the Artifact Refining Department was able to produce gratifying results so quickly - more importantly, this Fang Ding was not created under his own instructions and guidance, it was completely

It is the result of their own thinking and combined with existing technology.

This meant that he could be more relaxed in the future. Of course Liu Xuan was very happy, and he promised rewards to everyone in the Weapon Refining Department.

The most important members of the Weapon Refining Department are currently thirteen monks recruited by Shi Dao Ren through letters. Although the cultivation levels of these monks vary, they are all at a certain level.

In addition, the things Liu Xuan wants them to make are not advanced things. As long as they understand some basic technologies, they can start making them. More importantly, what Liu Xuan is doing is similar to assembly line operations. Even if they don't

If you understand and know how to do it, you can still produce it.

If it weren't for the fact that Liu Xuan didn't have enough people on hand who understood the methods of cultivation, there would be no need for these 'outsiders' to do these things.

Because of this, Liu Xuan also asked Zhang Rang to select several young eunuchs in the palace who were young, smart and smart to serve as apprentices in the Weapon Refining Department. Li Su also recruited some families from outside who had difficulty, but

Watch the clever children become apprentices and learn basic cultivation knowledge at the same time.

These children have been raised since childhood, and they will be the seeds for Liu Xuan to spread these technologies in the future, so they value them very much - they are basically under semi-house arrest, but these children have no worries about food and clothing here, so they don't care about that.

Raising his hand to pick up the quiver again, Liu Xuan tested the effect of the quiver, and he was also very satisfied.

"Can it be mass-produced?"

Shi Daoren shook his head: "It may be difficult at the beginning, but if those children learn quickly, they can make it faster!"

Liu Xuan pondered for a moment: "All quivers will be given priority to the Yulin Army!"

The Yulin Cavalry has a full strength of 5,000 men, which means that at least 5,000 quivers are needed. However, there will definitely be defective products during production, so it is not necessary to make many quivers to meet the demand of 5,000. Therefore,

Just such a goal is enough to keep everyone in the Weapon Refining Department busy for quite a long time.

What's more, Liu Xuan immediately gave instructions: "But before that, make ten of those square tripods!"

For now, ten square tripods are enough to meet the needs of coin issuance. After all, coins are produced when the ore is thrown in, and the manufacturing speed is much faster than that of ordinary workshops. Not to mention ten, even one is enough.

Instantly kill all official workshops in Chang'an.

Liu Xuan wanted to make ten of them because he thought about the future - he estimated that there would be no need to build these tripods in the future, and just ten of them would be enough to meet the needs of the entire dynasty.

"At the same time, the Weapon Refining Department should not just focus on making quivers. It is best to divide it into several teams. One team will focus on making quivers, and the other teams will do other things. If there are any novel ideas or new things made, and the

If you are useful to the court, you will be rewarded!"

He hopes that the Weapon Refining Department can independently develop and manufacture more things, but he also understands that this may not be high, and he still needs to guide the Weapon Refining Department's research direction.

"But for now, I still have to give you a general direction..." He lowered his head and pondered for a moment, remembering that although the Yulin Cavalry had a quiver to help solve the arrow problem, the armor problem has not been solved yet! I thought

Here, I have a calculation in my mind: "Find a way to come up with an armor whose defensive power is not much worse than that of heavy armor, but at the same time is light enough!"

After finishing speaking, he added another sentence: "The most important thing is that it must be beautiful enough!"

Hearing the last sentence, Li Su and others just nodded in agreement, but Diao Chan and Cai Yan covered their mouths and chuckled: "Your Majesty really values ​​these things very much!"

But Liu Xuan still had something to say: "This is related to the majesty of the imperial court. Do we want the elite cavalry of the imperial court to wear rags?"

Li Su and others had not yet retreated. They all nodded in agreement when they heard what Liu Xuan said. The elite soldiers and horses of the imperial court must not be too poorly dressed, otherwise others would say that the imperial court has declined to such an extent.

The most elite troops can no longer afford to wear armor!

Thinking of this, he naturally understood the importance of this task. Although Li Su was not responsible for the specific research and manufacturing, his enthusiasm was no less than that of Shi Daoren. After accepting the order, he took Shi Daoren and Sima Yi and left.

On the way, he also asked the two of them what materials they needed, and he would work hard to ensure all the needs of the Weapon Refining Department.

Watching a few people leave, Liu Xuan suddenly looked forward to the day when his Yulin Rider would wear the new armor made by the Weapon Refining Department and shoot an almost inexhaustible amount of arrows to the north.

While Liu Xuan was thinking about Yu Lin riding in the north, another elite troop under the imperial court had arrived at the border of Yanzhou.

The first general, wearing black armor, looked at the camp in front of him and smiled: "What if we let that black face serve as the vanguard? In this weather, why don't we, the Tiger and Leopard Cavalry, get to the ground first?"!
