Chapter 33 Account Book

Su You was speechless: "What you said is also true, but it is the most superficial thing. If you say that wood can make fire, then I tell you that water can also make fire. Do you believe it? Do you believe that light can also make fire? It's like earth making gold,

However, soil also produces salt, vitriol, pottery, and porcelain. How can we explain this?"

"We only start from our current experience, taking Yungang as an example. Your father and I first refined the pebbles to remove the sulfur gas and obtained pure carbon, which is finer in texture than charcoal and is called coke."

"Then mix coke and pure iron with river sand, blow it with a fan, and smelt it with high-temperature firepower."

"The texture of both is pure, so the iron obtained is very refined. Then add borax. Your father tried it, but it couldn't be removed even after ten forgings. He said that there is no one who is good at this in the world of crude steel."

"Well, the cloud steel we have now only consists of carbon and iron. If we continue to beat and fold it to remove the carbon, the texture of the crude steel will be solid at first. But as the smelting continues, too much carbon will be lost in the steel.

, it began to become soft and gradually turned into wrought iron.”

"Cut the wrought iron into small pieces and reuse the coke to make it. The carbon in the iron will be replenished, and you can get Yunnan Steel again."

"If you use a graphite pottery pot to smelt wrought iron, the iron properties will remain unchanged after quenching. If you add pure carbon powder to seal the smelting, you can turn the iron into steel. This proves that the only difference between steel and steel is carbon."

After speaking, he patted Shi Tong's thigh like a master: "If you don't believe it, you can try it with this piece of cloud steel and you will know that what I say is true."

Shi Tong still found it a bit bizarre. Su You's theory completely broke the theoretical system he inherited from his family.

Su You smiled and said: "The carburizing method I just taught you is actually another proof: how do the threads of bolts and nuts change from iron to steel? Isn't it because it is wrapped with a layer of carbon mud, which penetrates after being calcined?

Is it the reason for going in?”

"It doesn't matter if you don't believe it for a while. Make bold assumptions and verify carefully. This is correct. But the most urgent thing is to get what you want first."

Shi Tong then put aside his worries and said: "Master's words must be credible, otherwise my father would not be able to smelt such a sharp blade."

Su You said: "Actually, this blade has such good performance that it needs to be touched by the light of another element, but this is too far. By the way, your little lady likes weapons, and I promised to get them for her.

Can you get a good knife with green vitriol?"

Shi Tong was surprised: "Master has a sore?"

Su You was unhappy and rolled his eyes: "You just got a sore! Just prepare it for me."

Shi Tong smiled and said, "It depends on how much you use, master. If it's a little, you have to go to a drug store. If it's a lot, you have to go to the tax supervisor. This matter is also his responsibility."

Su You said: "Try two kilograms first."

Shi Tong said: "The green vitriol is crystal clear when it has not seen the wind, but when it is exposed to the wind, it is easily broken into powder. The tax inspector will usually transport it away quickly after receiving it. It is estimated that the inventory will not be too much. You can easily get a few kilograms."

Su You said: "I'm not picky, powder is fine too. By the way, you should have beeswax."

Shi Tong chuckled and said, "Whether others have come, Master, you have come."

Su You's face was tense: "I didn't say anything, you can't run away if you steal copperware! This matter will be troublesome if it comes to the situation. You can discuss it with your father and see if you can go to Dali and partner with others to build a copper mine.

Then directly make it into copperware, and then come over there..."

Shi Tong immediately beamed with joy: "Master is really united with us for the sake of my little wife. He has put all his efforts into it..."

Su You was puzzled: "It's all a mess! Apply beeswax to my triangle and ruler, and I'll take them back and let Yu Gong process them."

After speaking, he added: "You already understand the principle of screws and nuts, so you can find a way to make it smaller. I will install the compass tomorrow."

Shi Tong quickly said: "Wait a minute, Master, the tools you are going to make must be good ones, I will prepare a set for myself!"

Su You laughed loudly: "You are smart! Then I might as well come back and get it in the afternoon."

Back at the bookstore, the engraving workshop here is already in full swing.

Unmentioned, because of the application of plaster casts and calipers and small rulers, the production of ceramic codes immediately became efficient.

The engraving blocks are ready-made. You can directly turn the engraving blocks into clay tablets, then use a ruler to accurately draw the dividing lines, cut them with silk threads, separate them after drying, and then use calipers to accurately measure and polish them to a uniform size. In one day, a workshop can

Can turn out tens of thousands of pieces!

On the contrary, Lao Yu's family repaired the mud code and delayed some progress.

The best ones for reproduction are of course the two dictionaries Mrs. Cheng gave Su You, "Tang Yun" and "Guang Yun".

These two books collect almost all the text, and also have small-print annotations. This means that both large and small characters are available, and there are also these commonly used characters, so there are as many as you need.

If we carve this slowly, I am afraid that we will not be able to accumulate so many characters in ten years. Now, Lao Yu estimates that he can produce 50,000 or 60,000 in three days!

Cheng Wenying was almost overjoyed. How can this efficiency be justified? My nephew is truly a god!

Seeing Su You coming over, Cheng Wenying smiled as if he were seeing the God of Wealth: "My dear nephew, where have you been?"

Su You replied respectfully: "I went to the blacksmith shop to get a set of copper rulers and copper rules."

Cheng Wenying nodded: "How much money you need, go to the accounting office and let us know."

Su You waved his hand: "No, Shi Tong, the shopkeeper, recognizes me as his master."

Cheng Wenying was stunned and looked strange: "You know everything?"

Su You was confused: "What do you know?"

Cheng Wenying smiled and said: "Haha, it's nothing. How could he recognize you as his master?"

Su You said: "Oh, his grandfather Hengzhi and I have been friends for many years and have a good relationship."

Cheng Wenying clasped his hands and said: "Shi Fu, you are also one of the elders of Jiang Qing. It seems that I don't need to go to Shijiacun to plead for you."

Su You bowed and said, "The boy is so shameless, I've made my brother-in-law worried."

Cheng Wenying smiled and said: "Now I understand a little bit more about what you did. You will never be aimless. There will be a hit in the middle. It's just that others can't see through it."

Su You said: "In fact, after pigs are castrated, their ferocity is greatly reduced, and the meat quality will remain in the state of young pigs. And then you only know that if you eat fat, you will get more meat."

"Each village still uses grazing methods to raise animals, but they don't know that they can actually be raised in pens."

Cheng Wenying asked strangely: "Where did you get this weirdness from?"

Su You chuckled and said: "It is rumored that the ministers in the palace are all white and tender..."

Cheng Wenying let out a puff, then fell down laughing, waved his hands and said, "What a brain... hahahahaha..."

Until he laughed heartily, he said: "Although it is just a few pigs, it cannot be used as a set of jade porcelain or a bottle of Yongchun Dew. However, the country is based on agriculture, and my nephew also knows his heart in this farming work. It is good. It will be good for the future."

It will be helpful for people to serve as officials."

It depends on who is right. If any kid from the Cheng family dares to do this, Cheng Wenying will definitely ask the family to punish him for not doing his job properly.

As for Su You, no matter how you look at it, you like it, and no matter what you do, it's all right.

Now as long as Su You doesn't poke a hole in the sky of Meishan City, Cheng Wenying thinks it's not a big deal.

Su You said farewell to Cheng Wenying, and went to see Lao Yu first and asked him to carve the scale out of the waxed copper measuring stick. Then he went to his room to get two sets of rhyme books, and went to the opposite side to learn rhyme from Mrs. Cheng.

Mrs. Cheng is doing the accounting and looking through the account books with the shopkeeper.

Seeing Su You coming over, Mrs. Cheng praised the shopkeeper: "This is my arithmetic genius. You are right to find him."

Su You asked: "Sister-in-law, is there anything unclear about the accounts?"

The shopkeeper explained with a smile: "That's it, merchants from Jiazhou want to order a batch of orders, with a total value of 80 guan. They have already paid a deposit of 30 guan. We currently have about 15 guan in inventory. We are ready to spend this time.

One hundred guans were purchased from Chengdu and will be paid to Jiazhou merchants when the goods arrive next month. It is agreed that the money and goods will be paid, so it is a bit complicated to keep the account."

Su You smiled at Mrs. Cheng and said, "Can I read this account book?"

Mrs. Cheng said: "My brothers, it doesn't matter. The men in the family don't care about this. They just give me a headache."

The shopkeeper smiled and said: "In Jiang Qing's family, the young master's reputation for intelligence has spread throughout the family. I have heard about it these days."

Mrs. Cheng smiled and said: "Xiaoyou will go to school in the future, but if you know some housekeeping skills, you won't be easily deceived."

Su You smiled and said: "This is also my interest. It won't waste too much time."

I took a look at the ledger and saw that it was quite advanced. On a piece of paper, there were four headings: old management, new management, and expulsion.

Below are numbers, and each line is stamped with the verifier's seal.

After an explanation from the shopkeeper, it turned out that the four columns represented the balance of the previous period, the income of the current period, the expenditure of the current period and the balance of the current period.

As far as this Shanluo transaction is concerned, when the transaction is completed, the old management will have 15 guan in stock, the new one will receive 100 guan, the new one will be fired 80 guan, and finally it will become an actual 35 guan, with a profit of 20 guan, which is still good.

.

There is nothing wrong with the plan itself, and according to the shopkeeper, it is quite advanced.
