Chapter XXXIII Ledger

Su You was speechless: "What you said is also true, but it is the most superficial thing, if you say that wood makes fire, then I tell you that water can also make fire, do you believe it or not?" Light can also make fire, believe it or not? It is like the earth is born of gold, but the soil also produces salt, alum, pottery, and porcelain, how can this be explained? ”

"We only start from the current experience, let's take Yungang as an example. Your father and I first refined the charcoal to remove the sulfur gas, and obtained pure carbon, which was finer in texture than charcoal, and was coke. ”

"Then it is mixed with coke and pure iron river sand, and then it is blown into a fan and smelted with high-temperature fire."

"Both are pure in texture, so the resulting iron is very fine. After that, with the help of borax, your father tried, ten forgings and could not go to a point, he said that the world is coarse, there is no one who is good at this. ”

"Okay, then now the cloud steel, the composition is only carbon and iron, if you continue to hammer and fold, remove the carbon, the crude steel texture is still solid at the beginning, but as the smelting and forging continues, the carbon in the steel loses too much, it begins to be soft, and gradually becomes wrought iron."

"Cut wrought iron into small pieces and reuse coke to refine it, and the carbon in the iron is re-replenished, and Yungang can be obtained again."

"If wrought iron is smelted in a graphite clay pot, the iron properties remain unchanged after quenching, and if pure carbon powder is added to seal and smelt, iron can be turned into steel. It can be proved that the difference between steel and steel is only carbon. ”

After speaking, he patted Shi Tong's thigh with the appearance of 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 said is true." ”

Shi Tong still felt a little unbelievable, Su You's theory completely broke the theoretical system he inherited from the family.

Su You said with a smile: "The carburizing method I taught you just now is actually another proof: how to change the wire of bolts and nuts from iron to steel?" Isn't it because it is wrapped in a layer of carbon mud and penetrates into it after calcination? ”

"It's okay not to believe it for a while, make bold assumptions, and carefully verify it, which is true. However, the urgency of delay is to get the things you want right first. ”

Only then did Shi Tong put aside his troubles and said, "What Master said must be credible, otherwise my father would not have been able to cure such a sharp blade." ”

Su You said: "Actually, the performance of this blade is so good, and it needs to be stained with the light of another element, but this is too far." By the way, your little lady likes blades, I promised to get her a good knife, can you get green alum? ”

Shi Tong was shocked: "Master has sores? ”

Su You was unhappy and rolled his eyes: "You just have sores!" Get me ready. ”

Shi Tong said with a smile: "This depends on how much Master you use, if you have less, you have to find a pharmacy, if you have more, you have to find a tax supervisor, this matter is also in his charge." ”

Su You said: "Let's try two catties first." ”

Shi Tong said: "The green alum is crystal clear when it does not see the wind, but it is easy to break into the end when it sees the wind, and the tax supervisor will generally transport it away as soon as it receives it, and it is estimated that the inventory will not be too much." But you can get a few pounds at will. ”

Su You said: "I'm not picky, and powdered ones are fine." By the way, you should have beeswax. ”

Shi Tong said with a smile: "No one else came, but you came, Master." ”

Su You's little face was tense: "I didn't say it, stealing the bronze casting, you can't run!" This matter is a trouble, you discuss with your father, see if you can go to Dali, partner with someone to get a copper mine, and then directly make copperware, and then come from there......"

Shi Tong suddenly smiled: "Master is really with us for the sake of my little lady, this is a lot of thought......"

Su You was inexplicable: "What a mess!" I smeared my triangle and ruler with beeswax, and I took it back to be processed by Yu Gong. ”

After speaking, he said: "You already understand the principle of screws and nuts, then find a way to make them smaller, and I will install the compass tomorrow." ”

Shi Tong hurriedly said: "Wait a minute, Master, the tools you want to make must be good things, and I will prepare a set for myself!" ”

Su You laughed: "You're smart!" Then I'll come back in the afternoon. ”

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

Not to mention, because of the application of plaster turning and calipers and small rulers, the production of pottery yards immediately became efficient.

The engraving is ready-made, the engraving is directly turned into a clay plate, and then the dividing line is accurately drawn with a ruler, cut with a silk thread, separated after drying, and then accurately measured with a caliper and polished to a uniform size. At the end of the day, a workshop can turn over tens of thousands!

On the contrary, it is an old family, and repairing the mud code delays some progress.

The best ones to use for reprinting are, of course, the two dictionaries that Mrs. Cheng gave Su You, "Tang Rhyme" and "Guangyun".

These two books collect almost all the text, and there are also small text notes, which is the size and size of the code, and if so, there are also these commonly used word codes, which is how many and how many.

If this is carved slowly, I am afraid that ten years will not be able to accumulate so many characters, and now, Lao Yu estimates that he can make fifty or sixty thousand pieces in three days!

Cheng Wenying is so happy that he is about to die, where can he be reasonable in terms of efficiency? My virtuous nephew is truly a man of God!

Seeing Su You coming, Cheng Wenying smiled like a flower when he saw the God of Wealth: "Virtuous nephew, where did you go?" ”

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

Cheng Wenying nodded: "How much money is needed, go to the account room to inform you." ”

Su You shook his hand: "No, Shi Tong, the shopkeeper in the shop, recognizes me as a master." ”

Cheng Wenying was stunned, with a strange expression: "You know everything?" ”

Su You was inexplicable: "What do you know?" ”

Cheng Wenying smiled and said: "Hehe, it's nothing, how could he recognize you as a master?" ”

Su You said: "Oh, my father Hengzhi and I are friends and have a friendship. ”

Cheng Wenying clasped his palms together and said: "Shi Fu, I am also one of my Jiang Qing elders, it seems that I don't need to go to Shijia Village to intercede for you." ”

Su You bowed down and said, "The kid has no form, which makes the in-law worried." ”

Cheng Wenying said with a smile: "What you did, now I understand a little bit, you will never be aimless, you must be in the middle, just because others can't see through it." ”

Su You said: "In fact, after castration, the ferocity of the pig has been greatly reduced, and the meat quality will remain in the state of young pigs. Then I only know that Han eats fat, and there is a lot of meat. ”

"The villages are still raising in the way of grazing, but they don't know that they can actually be intensively raised in the enclosure."

Cheng Wenying said strangely: "Where did you know this weirdness?" ”

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

Cheng Wenying snorted, then laughed and fell, waved his hand and said, "You brain...... Hahahaha......"

It wasn't until he laughed heartily that he said: "Although a few mouthfuls of pigs are just a few mouthfuls, they can't deserve a set of jade porcelain and a bottle of eternal spring dew." However, the country is agriculture-oriented, and the virtuous nephew also knows how to work hard in this agricultural matter, which is very good, and it will be helpful to the people in the future. ”

It depends on who is right, if any kid in the Cheng family dares to do this, Cheng Wen should definitely ask the family law to punish him for not doing his job.

For Su You, it is how to look at it, how to like it, and how to do it.

Now as long as Su You doesn't poke a hole in the sky of Meishan City, Cheng Wen should think that it is not a big deal.

Su You said goodbye to Cheng Wenying, first went to find Lao Yu, asked him to carve out the scale of the copper measuring tape with wax, and then went to his room to take two sets of rhyme books, and went to the opposite side to find Mrs. Cheng to learn rhyme.

Mrs. Cheng was taking inventory and looking through the account books with the shopkeeper.

Seeing Su You coming, Mrs. Cheng praised the shopkeeper: "This is my family's arithmetic genius, and it is right to look for him." ”

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

The shopkeeper explained with a smile: "That's the case, Jiazhou merchants want to order a batch of single Luo, a total value of 80 yuan, has paid a deposit of 30 yuan, we now have about 15 yuan in stock, this time we are going to spend 100 yuan from Chengdu to buy, next month after the arrival of the goods together with the payment to Jiazhou merchants, said that the money and goods are good, this account is a little complicated to remember." ”

Su You smiled at Mrs. Cheng and said, "Can the little brother read this account book?" ”

Mrs. Cheng said: "My own brother, it's okay, the men in the family, they don't care about this, they give me a headache." ”

The shopkeeper said with a smile: "Jiang Qing's family, but the reputation of the young master's intelligence has spread all over the world, and the old man has heard it like thunder in the past few days. ”

Mrs. Cheng said with a smile: "Xiaoyou is going to study in the future, but if you know some housekeeping methods, you will not be easy to be bullied." ”

Su You smiled: "This is also the interest of the little brother. It won't take too much time. ”

I took a look at the account book, and it was quite advanced, and on a piece of paper, it was divided into four headings: the old tube, the new income, the expulsion, and the truth.

At the bottom are the numbers, and each line is stamped with the seal of the verifier.

According to the explanation of the shopkeeper, the original four columns represent 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 single transaction is concerned, by the time the transaction is completed, the old pipe is 15 times of inventory, the new income is 100 times, the expulsion is 80 times, and finally it becomes 35 times and the profit is 20 times, which is still good.

There is nothing wrong with the calculation itself, and the meaning of the shopkeeper is quite advanced.

In most places, the three-pillar accounting method is still popular, that is, the old management is missing, and Meishan has developed business, and the accounting method is ahead.
