It would be great if there was iron. Humans cannot do without steel. Even if there was no iron, iron ore. As a materials expert, although he had not studied smelting specifically, he understood the principles. He may not be able to make special alloys. Needless to say, ordinary cast iron and cooked iron should be fine. Ordinary steel should be fine. If he spends some effort, he will be confident to handle the most ordinary alloys.

The nearest iron ore location of the sacrifice has been sent out, and the first sacrifice is free!

A strange thought arose from the bottom of my heart. For some reason, Zhang Xuan knew about a mountain less than 30 miles away from Lilan County. He knew very certainly that the iron ore there was 500,000 tons, 52% taste, and the quality was hematite...

Zhang Xuan was confused. How did I know? Why did I know? What kind of sacrificial rituals are?

oh!

This... is this the legendary welfare link, the plug-in of the time traveler?

I didn’t see the system, nor did I have an old man, and I didn’t even have an expanded portable space. I had a bad review!

Zhang Xuan was not surprised by this sudden sacrificial sacrifice, only a little excited. At least this reincarnation was not a result. The family of the fetus was not very good, and he was also a second-generation official. The plug-in looked not strong, at least there was.

After discovering the so-called sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial

Recalling the state of the sacrificial ritual when the sacrifice appeared before, Zhang Xuan felt a little puzzled: It’s not enough to have iron ore. It would be great if there was another coal mine, so that it could be smelted.

The nearest coal mine location requires 100,000 coins or equivalent items.

It was here, and it was indeed here. Zhang Xuan trembled slightly excitedly. He wanted this. As for sacrifices, Zhang Xuan didn't care. He didn't really need a coal mine. He just wanted to try it. Is this sacrifice similar to the system the kind of thing he thought about?

It turns out that it really exists, just don't know where, deep in the brain?

A few minutes later, Zhang Xuan calmed down and curled his lips. He really dared to ask for 100,000 knives. With another memory in Zhang Xuan's mind, he probably knew the value of the knives.

The Great Zhou is a relatively primitive world, in the mixed period of the Stone Age and the Bronze Age, when the poor use pottery and stone tools, and the rich use bronze tools. Most of the commercial activities are bartering, and the concept of coins has been formed, but the usage rate is too low. The benchmark currency is not a knife currency, but food.

Taking Lan County as an example, the per capita GDP is less than 100 yuan, which is the result of conversion. In fact, except for the county people, that is, the urban people in Lan County, the Lizheng, Su Lao and the big landlords in the village have the opportunity to use sword coins, and civilians have never seen money at all.

Copper is used more in the Great Zhou Dynasty than in coins.

Hundreds of thousands of coins?

Zhang Xuan suspected that if he could not find so many of the sword coins in Lan County were gathered together.

Copperware, copper material, knife and coins are all copper themselves, but their values ​​are different.

The value of copper ware is higher than that of copper materials. After all, they have been processed by copper smiths and have manual fees. In addition, according to the style of copper ware, the quality and value vary greatly. Copper ware cannot be used as currency. It itself is just a ware and belongs to the "goods". It can be bartered with goods and has no benchmark value of currency.

Similarly, copper materials are also "goods" and are bartered according to their quality.

Only sword coins are the real money.

"Zhang Er" Zhang Xuan shouted.

"My master, here, you give me instructions." Zhang Er came out of nowhere. This kid was clever and could not see anyone. Only when Zhang Xuan needed him, he could always appear next to Zhang Xuan as soon as possible.

"Go and get a few sword coins."

After not much effort, ten sword coins appeared in Zhang Xuan's hands. This trick was similar to the sword coins in memory. There were three parts: the blade body, the handle, and the knife ring. Some had words on it, and some were light boards without words.

The sword and coin system of the Great Zhou Dynasty was also chaotic, not completely built. Twenty palaces had minting. In this era, there was no concept of coin rights at all. The reason was very simple. The production technology here was too poor. If you want to cast copper into knife and coins, the cost was too high, and you could not even cast it.

In Zhang Xuan's opinion, the characters cast on the sword coins are very simple, but in the Great Zhou Dynasty, these sword coins with characters are made by 800 officials, and they are minted by the Great Zhou royal family. It is hard to say that those without words are mostly from the nineteenth palace, and some are made privately. The quality and size are completely different, and the advantages and disadvantages can be seen at a glance.

"Zhang Er, how much does a stone of rice cost?" Zhang Xuan's knowledge of the prices here is limited, and he can't find them in his memory. After all, he is the top yamen in Lan County. Although he is studious, he doesn't care much about people's livelihood.

"My master, recently, a stone of rice costs twenty-two cents." Zhang Er replied in a low voice. Today, Mr. Xiao is so strange that he actually asked about the price of rice?

Zhang Xuan thought in his mind that although Lan County is a low-court, people's livelihood is pretty good. You don't have to think about eating enough. It's already good to be able to eat 80% full in half of the year. In the remaining half of the year, you can only deal with it.

In this era of lack of oil and salt, it is necessary to consume a pound of corn per day per person, and less of it is a hunger category. In this way, adults need to consume at least four stones a year, which is 88 cents.

The per capita GDP is about 100 yuan. By doing this, minting coins is basically not profitable, and even if you don’t get it right, you will have to lose money. After all, in addition to eating, people also have to wear clothes and travel, which is consumed.

I had a headache. I originally thought that it would be very simple to calculate an ancient business system and monetary system based on my own knowledge, but the more I calculated, the more confused I became.

"Zhang Er, which one is more cost-effective, copper materials, copper ware, and knife coins?" Zhang Xuan asked. Although he had the original memory of Zhang Xuan in his mind, he was not as good as the indigenous people here.

Zhang Er opened his mouth, not knowing how to answer. He couldn't understand what his master said. He understood every word, but what does it mean? And what does it mean?

"Okay, to put it another way, which of these three things do you like? In the same number, you can only choose one." Zhang Xuan also realized that this kid should not understand. The question he asked had already involved a relatively complex business and economic system. He had not figured it out himself, and it would be a bit too much to expect a servant to understand.

"Dao Coin." Sure enough, Zhang Er had an answer without any hesitation this time.

"Why?" Zhang Xuan asked, he couldn't understand the thinking of the ancients.

"It's convenient. With knives, you can buy copperware or rice. You can buy anything you need. If copperware is not good, most people can't afford it, and copper materials are the same." Zhang Er replied.

Yes, yes, I understand, the currency equivalent and settlement unification are the same, Zhang Xuan feels that he is the level of an economics expert here.

Cash knives?

It is useless to count on Lan County for 100,000 knives. Looking at the entire Luoxia Prefecture and the five counties, it is hard to say how many knives you can take out. If Zhang Xuan wants to continue using that sacrificial system, minting coins by himself is the best choice.

Of course, you can also use equivalent items for sacrifices, but the four characters of equivalent items are relatively vague. If you have more wealth in your hands in the future, you can try it out. I am afraid it won’t work at the moment.

For example, using corn as an equivalent amount requires more than 4,500 stones, and more than 450,000 kilograms of corn. This amount may not be able to be taken out in the rice warehouse of Lan County. Even if there is one, the county magistrate and his father will not give it to him.

Regardless of whether he can take it out or not, Zhang Xuan would not be so stupid as to get 100,000 knives to exchange for a coal mine. He could use other methods to find a coal mine, which would definitely cost much less than the sacrifice.

"My master, I'm leaving the yamen, and I'll call you to see him." An old man with a short figure, wide shoulders and a big body, and a huge copper sword behind his back, walked to the two of them quietly and said.

"I know Uncle Ma." Zhang Xuan responded and walked towards the outer courtyard. The one who was carrying a sisal face was his father's comrade-in-arms, and now the chief manager of the family. In Zhang Xuan's opinion, this Uncle Ma was extremely insecure. No matter when and where, even if he was sleeping, he would never leave his sword. When he was a child, Zhang Xuan wanted to see his giant sword that was as wide as an adult's palm, but he was ruthlessly rejected.

In fact, Uncle Ma is very good to Zhang Xuan. Uncle Ma is not married, nor has children. He regards Zhang Xuan as his son. He is more doting towards Zhang Xuan than Zhang Mo. Only that sword is a taboo for Uncle Ma, and it is impossible to ask any more questions.

In the outer yard room, Zhang Mo sat tiredly on the couch. On the small table in front of the couch, there was a bowl of warm turbid wine. Every day, a bowl of warm wine was placed in the yamen. It was Zhang Mo's few fun.

Recently, Lan County has been in trouble. The spring tax that Luoxia Prefecture has just collected was robbed fifty miles away from Lan County. Although the spring tax is a population tax and a small tax, the robbery tax is a big case. If the spring tax cannot be recovered in time, Luoxia Prefecture officials and county officials in the five counties will not have a good life.

The complicated things in the county, coupled with the major tax robbery case, Zhang Mo was exhausted. The boy who was usually well-behaved at home actually had to cause trouble. Can copper materials be moved lightly?

Zhang Xuan walked into the room and bowed. The eight-foot-tall uncle in front of him, who was a little handsome, was the father of this life, the eighth-rank county magistrate Zhang Mo.

"father."

"Well, why do you want copper?" Zhang Mo would ask Zhang Xuan about his studies, or talk about political affairs in the county, so that his son could broaden his horizons and increase his knowledge. Zhang Mo was not in this mood today.

"I'm going to cast a copper pot," said Zhang Xuan.

"What's the pot?" Zhang Mo asked. There was no pot in the Great Zhou Dynasty, so he only ate the cauldron. The cauldron is the most important cooking utensil. The civilian stones and the cauldrons used for scholars are half a reflection of the rule and status, while the other half is because he was too poor and lacked supplies.

"A food device." Zhang Xuan explained.
