After Wu Dapeng finished sending a message to Wanshida in sign language, he turned his eyes to the street. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

He didn't have the fear of this time and space in his heart, but looked at the pedestrians on this bluestone street boringly, and said in his heart, this broken mountain village, I thought it was a town, and it seems that the flow of people is not small.

At this time, he unconsciously cocked Erlang's feet, touched the pectoralis major muscle that was now redeveloped again with his hands, and while shaking his legs, he thought, this young man is really good, he feels that he has endless energy in his body, and he even wants to find someone to fight...... Why was he a mess back then......

Wanshida pulled out a few real copper plates from his arms...... Lined up on the table, he asked, "Brother Li, I will use this money in the country...... I wonder if it's available here? Yes...... The Great Song Dynasty copper coins that we had with us had already been used up at this time......"

Wan Shida looked at Li De's surprised appearance with satisfaction, this is brass, what about electrolytic copper, if you are not surprised, I will be strange.

The earliest use of brass to cast coins in China began in the Jiajing period of the Ming Dynasty.

The word "brass" was first seen in the "Shen Yi Jing and Zhonghuang Jing" written by Dongfang Shuo in the Western Han Dynasty: "There is a palace in the northwest, brass is the wall, and the palace of the emperor is inscribed."

What kind of copper alloy does this "brass" refer to remains to be examined.

There were indeed brass products in this period, and it cannot be ruled out that the ancient craftsmen happened to find suitable copper ore containing copper and zinc, and there were all kinds of coincidences when smelting...... Therefore, Jiajing also had brass products before, but by no means on a large scale...... It is still dominated by red copper and bronze products, and brass is generally very rare.

The term brass refers specifically to copper-zinc alloy, which began in the Ming Dynasty, and its record is found in the "Brass Ming Huidian": "Jiajing Zhong rule, Tongbao money is 6 million wen, and the two flames of brass are 47,272 catties ......."

Through the analysis of the composition of copper coins in the Ming Dynasty, it will be found that in the coinage mentioned in the Ming Huidian, the appearance of brass in the real sense is much later than that of other copper alloys, because it is difficult to obtain the metal zinc in brass, and the ancient craftsmen are far from realizing zinc.

Zinc oxide can be reduced to metallic zinc relatively quickly at a high temperature of 950C-1000C, and zinc has boiled at 906C, so the metallic zinc obtained by reduction can only exist in the form of vapor.

Only when this vaporous zinc reacts against it when it is cooled will it become elemental zinc. Otherwise, the vapor zinc will be re-oxidized to zinc oxide by the carbon dioxide in the furnace, so a special condensing device is necessary to obtain the metallic zinc.

This is one of the reasons why the use of metallic zinc came much later than that of copper, lead, tin, iron, and one of the reasons why brass coinage appeared later.

In fact, the ancients of the Ming Dynasty did not know about this, they just put copper and zinc ore in closed furnaces to smelt together...... It belongs to empiricism, knowing what it is, not knowing why it is.

At this time, Li De carefully picked up one, looked at it seriously and repeatedly, and said: "Two brothers, this thing is different from red copper, and even more different from bronze...... But the legendary brass? Look at this color...... Perhaps...... Don't use it as an ordinary copper coin......"

Wan Shida said, "How about I exchange some with you?" ”

Li De waved his hand again and again and said, "Absolutely not!" It's a very unfair exchange......"

Wang Defa said: "Then you can count more copper coins with me......"

Li De said: "If you are alone, where can you bring so many copper coins...... Even if you have copper coins, you don't want to exchange them. ”

Wanshida said, "Why? Are you afraid that the copper coins I am waiting for are not from the right way? ”

Li De's face changed and said, "How does Brother Tai think like this? The top of this copper coin is extremely smooth, and the edges are not made of Fan...... But it can be the same size, and it is by no means all the ...... on the market in the Great Song Dynasty."

After Li De finished speaking, he took out a small purse from the baggage, poured out the contents of the contents, and the table suddenly became a coin stand.

There are copper coins, iron coins, paper money, long strips, and round coins.

Li De said: "If the copper coins in the hands of Brother Tai can be integrated into twenty or thirty times and made into bronze ware, they can get ten times the benefits; If it is made into armor, it is difficult to say a hundred times...... So how can I exchange it with you? ”

Wan Shida looked at the money on this table and said in his heart: What this product said is not a lie......

Wang Defa said: "But we really don't have any other change to use, and we can only use this currency for this breakfast...... It's better to exchange some with brothers. ”

Li De said with a smile at this time: "It's easy to say, it's easy to say, I can exchange some with you, so that you can go to Lin'an County...... There are a number of big shops there, and you exchange them with them...... That's for the best. ”

After that, Li De selected more than dozens of copper and iron coins and said: "If you count it as five times, these coins are enough for you to use them on the road...... Dozens of miles away, in the blink of an eye. ”

Wang Defa said: "I will agree to this ratio, and I will change some more, but what if I find a lost companion?" ”

Li De also remembered it, so he said: "Yes, I forgot about it......"

After saying that, he added a few more.

After the calculation, that Li De said: "If you regret it, after seven or eight days, you can go to the Li family Saburo Crude Medicine Shop to find so-and-so, and so-and-so will be in ......."

And when he had said that, he was to take his leave...... Wan Shida laughed loudly: "Brother Tai, I will give you a great fortune, do you want it?" ”

In Wanshida's imagination, after hearing this, this Li De should show an expression that adapts to the hand style, it should be: smile faintly, you say, what am I listening to.

But Li De didn't, but he smiled bitterly, and arched his hand and said: "I understand, there must be something good in the goods of the two of you------"

“？？？”

Li De said again: "When you arrive in Lin'an County, you will say that there is really something important to do now. ”

"Hahaha, how much profit do you have to receive that herb?"

Wan Shida thought to himself, my anti-inflammatory, antipyretic and painkillers here are all like miracle drugs for you, mix with us, your benefits are great!

Who said this idiot: "It's this time of year to buy, you can't change it without notice!" ”

After saying that, this fool directly settled the account with the old woman, and said goodbye with his hands lightly, turned around and left, moving quickly.

People are like this, it's not good for these three people to come forward and intercept them, right?

The three of them watched in amazement as Li De walked leisurely towards another mountain road with a burden on his back.

Wan Shida was a little annoyed, and he said angrily: "This stupid Boyi is sick! Did he listen to me? ”

Wang Defa said slowly: "This birdman hasn't seen the real thing, we shouldn't want to capture the old guy------ just take out the real guy directly, he doesn't just kneel down and worship?" Think of us as big brothers? ”

Wu Dapeng chuckled and said, "That's not right. This kid has a way------ he knows that we can't sell it here, and when we get to the county seat, we can only look for him, and if he can't get it, he can still offer a good price, and now he can't get the money anyway, and he pretends to be moral...... This kid has a way. ”

The other two thought about it, but didn't figure it out.

Seeing that the Song people came here to buy steamed cakes one after another, the three of them looked at each other and withdrew.

The three of them slowly crossed the stone arch bridge. They also need to find out what the other side of the stream looks like.

Wang Defa pointed to the rut marks on the stone bridge and said, "Look at the rut marks on the stone slab, this bridge is at least 100 years old......

After crossing the bridge, there were obviously fewer people. Most of them are blue bricks and tiles, and there are sometimes thatched houses, but they all have yards, and the yards are not small.

Some hung with long copper locks, while others were ajar.

There's nothing to look forward to...... The three of them didn't believe that such a place could be exchanged for any good goods.

The three of them returned to the bridge.

The huts turned out to be taverns...... There are no customers yet.

The three of them discussed it and decided to buy a few stir-fried vegetables, get some wine, and go back to the mountains to eat.

After Wan Shida entered, he shouted: "Bartender, cut ten catties of beef, and add twenty catties of wine!" ”

A bartender wearing a cyan turban came over with a smile, and the bartender said: "The villain only sells mutton here, but there is no beef, so he wants all the fat sheep and fat fish." ”

After all, Wanshida was born as a civilized person, and it was impossible for him to jump up and beat up the bartender to be a hero.

Wan Shida said in a rough voice: "Then finely cut ten catties of mutton and garlic paste...... Do you have soy sauce here? ”

The bartender said, "There's the sauce too, there's the oil...... The villain didn't hear about soy sauce ......"

Well, it's really backward.

"And what kind of sauce are you here?"

"The beans and noodles are steamed, mixed into a yellow sauce, adjusted with underwater salt, and exposed to Heri ......"

Wan Shida rolled his eyes, fuck, this is Miso! …… I can eat it, too.

"How do you make fat fish?"

"Steamed, stuffed fish, fish soup villain has a famous ...... at home"

Well, it's okay.

"Steamed three, add two side dishes, ten steamed cakes, and twenty catties of wine, and a bird fades out of the mouth! How much does it cost? Pack them all for me, and I'll take ......."

The bartender's lips moved slightly, and then he said, "I don't know if the guest officer will pay...... Huizi, iron money...... Or copper coins......"

"How?"

"If it is a meeting, it will cost 20 and 500 words; If it is an iron cylinder, then it will run through all directions; If it's a copper coin, it's two ...... two hundred dollars."

It's so expensive, it's less than a tael of silver in that Water Margin...... This guy is ripping off!

"What if it's silver?"

Wanshida said with a sneer, and took out a silver collar or two from his arms.

The bartender took one look at it and said, "Two taels is enough." ”

Wang Defa and Wu Dapeng found a seat at the door and sat down, just in time to see the wheelbarrow parked at the door.

Wang Defa shouted: "Inflation! ”

Of the four people who heard this, only three could understand it...... Wan Shida suddenly understood that during this period of Song Lizong, due to the great military pressure, the Great Song Dynasty government often over-issued meetings, and the result was often a sharp rise in private prices...... Now it seems that it is okay, and in a few years, it is possible to rise more than ten times compared to the Northern Song Dynasty.

In the end, the bartender prepared everything they wanted, a large food box, and four wine gourds.

On the way back, the three of them did the math...... I feel that the price of goods is similar to that of the world.

You see, one tael of the Song people is forty grams, and two taels of silver is a maximum of three hundred and twenty yuan...... How much is that cooked mutton pound? Forty-two bucks!

This Song is still big, and it should have more than 600 grams......

But everyone thinks that the algorithm is not right, but they can't find a reason.

I still don't understand who has the highest prices in the world on both sides.
