"It's ......"

Liu Xuan immediately understood what this tripod was for, to put it bluntly, it was the same principle as the quiver, but the quiver came out of the arrows for the bow and crossbow, and the tripod came out of coins.

He took a copper coin from Shi Daoren's hand, and unlike the square hole money that was originally used, although the coin from this tripod was still round, it did not have a square hole in the middle.

Since the Qin Dynasty unified the world, it abolished all kinds of miscellaneous currencies and unified the currency system, and square hole money officially became 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, and the overall did not change much.

It was not until Liu Xuan promoted the status of Shangshu and determined that the Six Ministries were the most important political affairs handling institutions in the court, and the status of Jiuqing was reduced, that it was quite different from the Qin Dynasty.

And the coins have also been inherited, and the square hole money is also the main currency in circulation in the Han Dynasty, but this history seems to end here.

Flipped the coin in his hand back and forth a few times, and looked at it carefully - he found that there was no pattern on both sides of the coin, only words, Liu Xuan glanced at it casually, and then didn't look at it again.

Because Shi Daoren casually took out another piece of silver ore and threw it into Nading.

Then he took out a small handful of silver coins as before, and the appearance was basically the same as that of the copper coin, except that it had different colors because of the different materials.

Then Liu Xuan doesn't have to look at it, it seems that this Baoding can make gold, silver and copper three currencies, but what he is really worried about about the implementation of the currency is not minting, but fake coins, which Xun You should know.

"However, Gongda is not the kind of person who messes around, since he proposed to let the Refining Division make this treasure tripod, he must have some idea, right?"

Thinking so in his heart, Liu Xuan asked Shi Daoren beside him: "What is the difference between the coins made by this Baoding and the coins minted by ordinary people?"

If Xun You thought of a solution, then he would definitely tell Shi Daoren and let him take this into account when making it.

I only listened to Shi Daodao: "Xun Shangshu made a request at the beginning, and it is precisely because of this that this tripod is a little more troublesome to make." ”

"Oh?"

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

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

There was no sound, and even if these two small metals collided together, what would be the sound?, but what happened next surprised those present......

Although Li Su had already seen it, he still felt that it was magical, and sighed at the wonder of this immortal method while staring.

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 each emitted a soft light, the light was not dazzling, but it was very clear, and even in the daytime, the coins could be seen to be glowing.

The light emitted is the same as the color of its own material, and then the light will slowly fade until it disappears, but as long as the Stor strikes the coin harder, it will emit light again.

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

After he thoroughly understood Xun You's thoughts, he also had to be amazed by Xun You's intelligence, this method is very simple, and more importantly, almost anyone can distinguish the authenticity of a coin anywhere and any place.

This method is actually not difficult, that is, to add an additional process to the ding, so that when Baoding makes coins, add a magic circle to each coin. It is also because of this that the coin is not minted in a pattern with an outer circle and an inner square.

This magic circle is not complicated, and in most cases it can even be said that it has no effect at all, the only effect of this formation is to convert the impact force into bright light when it is impacted, and the stronger the impact force, the stronger the transformed light.

Such a simple method directly distinguishes between genuine and fake coins, which is much more convenient than Liu Xuan's original idea of adding a magic circle to the coin, and then semi-determining the authenticity through a specific facility (money detector?).

Liu Xuan's idea, the real problem that is difficult to implement is that the money detector cannot be popularized, and ordinary people cannot judge the authenticity of the currency they hold at the first time, so there is still room for the survival of fake coins.

But Xun You's method can make everyone who gets the coin half tell whether they are holding a real coin or a fake coin for the first time, and more importantly, this technique is only mastered by Liu Xuan, he doesn't believe that those guys with cultivation will go to mint fake coins to play. Even those guys in Nanhua who want to oppose themselves can't put their minds on this, because there is no such thing as economic warfare in this era.

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

As for Sizhou, we still have to deal with some remaining issues first, and there is no need to worry about the currency issue.

"Good!"

Reaching out and taking two coins to play with in his hand, Liu Xuan was happy that the Refining Division had been able to produce gratifying results so quickly—more importantly, this Fang Ding was not made under his own instructions and teachings, but was completely made by his subordinates by thinking on their own and then combining the existing technology.

This means that he can be more relaxed in the future, of course Liu Xuan is very happy, and he casually promised a reward to everyone in the Refining Division.

At present, the most important members of the Refining Division are the thirteen monks recruited by Shi Daoren through letters, and although the cultivation of these monks is uneven, they are more or less of a certain level.

In addition, the things that Liu Xuan wants them to make at present are not advanced things, as long as they understand some basic technologies, they can start manufacturing - more importantly, Liu Xuan is engaged in similar assembly line operations, even if they don't understand it, they can still make it if they know how to do it.

If it weren't for Liu Xuan's hands not having enough people who knew how to cultivate, he wouldn't have needed these 'outsiders' to do these things.

Because of this, Liu Xuan also asked Zhang Rang to select a few young, clever and clever eunuchs in the palace to go to the Refining Division as apprentices.

These children have been cultivated since childhood, and in the future, Liu Xuan will spread these technologies into the seeds, so they are very important - they are basically under semi-house arrest, but these children don't have to worry about food and clothing here, and they don't care about those.

Raising his hand and picking up the quiver again, Liu Xuan tested the effect of the quiver, which made him very satisfied.

"Can it be mass-produced?"

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

Liu Xuan groaned: "All the quivers are given priority to the Yulin Army!"

Yulin rode a full crew of 5,000 people, which means that at least 5,000 quivers are needed, but there will definitely be defective products when manufacturing, so it doesn't have to be how many to really make to meet the needs of these 5,000, so just such a goal is enough for everyone in the refining division to work for a long time.

What's more, Liu Xuan immediately gave instructions: "But before that, let's make ten of that Fang Ding first!"

For now, ten square tripods are enough to meet the needs of coin issuance, after all, this ore will be thrown into the coin, and the manufacturing speed is not much faster than ordinary workshops, let alone ten, even if there is only one, it is enough to kill all the official workshops in Chang'an.

Liu Xuan wanted to make ten, completely considering the future - he estimated that this Fang Ding would not need to be built in the future, and ten would be enough to meet the needs of the entire dynasty.

"At the same time, the refining department should not patronize the manufacture of quivers, it is better to divide into several teams, one team concentrates on making quivers, and the other teams do other things, if there are any novel ideas or new things that are useful to the imperial court, there will be a reward!"

He hoped that the Refining Division would be able to independently develop and manufacture more things, but he also understood that this might not be high, and he still needed to guide the research direction of the Refining Division on the side.

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

After saying that, he added: "The most important thing is to be beautiful enough!"

Hearing the last sentence, Li Su and the others just nodded yes, but Diao Chan and Cai Yan covered their mouths and chuckled: "Your Majesty really attaches great importance to these!"

But Liu Xuan still had something to say: "This is related to the majesty of the imperial court, do you want to make the elite cavalry of the imperial court wear tattered?"

Li Su and the others hadn't retreated yet, and when they heard Liu Xuan say this, they all nodded yes. The elite soldiers and horses of the imperial court naturally can't be too bad in terms of dress, otherwise others will say that the imperial court has decayed to such an extent that even the most elite troops can't afford to wear armor!

Thinking of this, he naturally understood the importance of this task, although Li Su was not responsible for specific research and manufacturing, but his enthusiasm was not lower than that of Shi Daoren, after receiving the order, he took Shi Daoren and Sima Yi away, and asked the two of them what materials they needed along the way, and he would try his best to ensure all the needs of the Refining Division.

Watching a few people leave, Liu Xuan suddenly looked forward to the day when his Yulin Rider wore the new armor made by the Refining Division and used almost endless arrows to cross the north.

And just when Liu Xuan was thinking about Yulin's riding across the north, another elite army of soldiers and horses under the imperial court had already arrived at the border of Yanzhou.

The first general, dressed in black armor, looked at the camp in front of him and smiled: "What about letting that black face be the vanguard? In this weather, didn't we tiger and leopard ride to the ground first?" (To be continued)
