Infrastructure masters in the red building

After Jia Fang recognized that page of "Theory of Everything", he immediately felt chills in his heart.

He ordered a lot of "Primary Chinese" and "Primary Mathematics" from "Tianyi Bookstore", so he knows how much it costs to print a book.Last night, the fourth prince asked people to distribute the books for five cents a piece, which was simply bleeding out of their pockets.

But just after one night, the pages of the "Theory of Everything" have already appeared on the market stalls, and the pages printed with the three laws of mechanics are being used to wrap goods at this moment.

The owner of the stall selling water chestnuts was a woman in her 40s. Seeing Jia Fang staring blankly at the packaging of those water chestnuts, she smiled and said, "Master, are you afraid that the paper will break easily after getting wet? Actually No, it’s pretty good paper, it’s not easy to break no matter how soaked in water..."

Jia thought at ease: That’s right. When Shui Xian opened “Tianyi Bookstore”, he said early on that the paper used in their bookstore is definitely the best paper in the world.

The paper with the best printing and the package is also top-notch, which is really a bit too ironic.

"If you don't like it, I'll give you a lotus leaf—"

Jia Fang shook his head, said "no" and asked as calmly as possible: "Auntie, where did you get the paper you used to wrap the water chestnut?"

"Damn, you're asking this. It's our family. Last night in Dongmen City, someone coaxed me to buy this for five cents."

Jia thought at ease: Sure enough...

"Both of us were blind. We showed it to the gentleman who could read on the street. He said that he had nothing to do with Guan Pu. We were cheated out of five cents..."

Last night, the fourth prince distributed "The Principle of All Things". He did say that he should study this book carefully, and that he would definitely win if he encounters a gamble like the pagoda experiment in the future.This has caused many people to pay for this book because they are greedy for small profits.

"But I look at this writing paper, it's really good. Even if I buy dried lotus leaves, it will cost five or six dollars, so I just use this, just like that dead ghost took the money to buy a stack of dried lotus leaves last night." When Ye came back, thinking about it this way, my anger also calmed down."

Jia Fang was not angry at all at this time, turned his head back very calmly, asked Zhao Cheng to count the copper coins to the stall owner, and handed over the water chestnut wrapped with the "theory of all things" to Li Qingsong to hold.

In any time and space, it is not easy to reverse the concept and promote change.

Like King Qing in the past, pushing his hands from top to bottom, he still faced tremendous pressure, and was even completely liquidated after his death; the fourth prince chose a bottom-up method last night, wanting to use the method of distributing books to enlighten the people's wisdom, so that The common people spontaneously realized that this step was too big, and there must be someone similar to this stall owner. They couldn't understand the deep meaning behind it, but all this had nothing to do with them...

Jia Fang tried his best to adjust his mentality and told himself that the road is tortuous and the future is bright.The fourth prince had already anticipated such a result when he did such a thing last night, and was prepared to bear the loss.With so many books distributed, even if it only attracts one percent or one thousandth of the attention, it has already achieved its goal.

But when this kind of thing happened, Jia Anxin was still a little bit depressed—it was inevitable.

He turned around and went to Baigongfang in Datong Lane. He was familiar with the way, and went directly to the backyard to find the craftsmen he was familiar with.

Unexpectedly, the courtyard that used to be bustling is quiet now, and no one knows where they have gone.Jia Fang turned around, only to find that the craftsmen were all gathered in the hall where their daily affairs were discussed - this hall is also the place where Jia Fang used to explain the structural diagrams and principles to them.

When Jia Fang entered the hall, no one noticed him. On the contrary, the craftsmen held a book in their hands, some were frowning and reading, and some were lying on the table to write and draw.

But Jia Fang knew their origins. This hundred workshops claimed to have gathered the best craftsmen in the world, but half of these craftsmen were semi-literate and couldn't read a whole bunch of big characters-let them read books, it was really the sun coming out of the west.

Jia Fang didn't make a sound, and quietly approached the old coppersmith boy, watching him holding a bald pen very clumsily, laying a piece of paper flat in front of a book, and drawing one after another strange pictures on the paper. graphics.Old Tong is also one of the craftsmen with limited literacy. It seems that according to his own understanding, he is drawing the contents of the book that others have said once into "ghost symbols" so that he can remember them.

Jia Fang looked again, and the book in front of the old boy was none other than "The Principle of Everything".

Looking around quietly, Jia Fang discovered that these craftsmen actually had a copy of "The Theory of Everything", and everyone read it intently, as if they were gnawing on the "hard bones".

"Third Master, Third Master Jia!" Suddenly someone found Jia Fang entering the room, and the hall immediately became lively.

"Third Master, I saw the friction you mentioned in this book, friction! I understand, I understand, why does Third Master have to fix the copper rail!"

"Hahaha, I thought it was strange at the time, but now I am also a person who understands the truth!"

The coppersmith stretched out his hand and quickly grabbed Jia Fang, very excited, "Third Master, I finally saw you, tell me, tell us, what is the difference between the 'fixed pulley' and the 'moving pulley'..."

Jia Fang waved his hand: "Everyone, don't worry, come one by one, I will answer one by one, everyone has a share, and we will never fail."

Jia Fang, who had just been beaten at the market, now saw that the craftsmen not only loved the book, but also gradually confirmed the abstract principles with the concrete phenomena they saw every day. Jia Fang felt relieved.

"Old boy, go and get the rope, the axle, the wooden frame, and the iron nails, let's do an 'experiment'!" Jia waved his hand, and everyone in the hall rejoiced. They all called, planning to listen to Jia Fang's reasoning and do experiments together.

After a while, the hall in Baigongfang was crowded with people, and it seemed that no one wanted to do business anymore.Jia Fang even heard someone say behind him: "Is that the so-called 'Heir of Luban' coming? Let me meet, let me meet!"

Luban, Gongshuban, the most famous inventor in the Warring States period, the ancestor of craftsmen, it is said that various tools used by later carpenters, such as drills, planes, shovels, curved rulers, and ink fountains for marking lines, were all invented by Luban.

Now in Baigongfang, the craftsmen also offer Luban's tablets, begging this patriarch to bless the disciples and grandchildren of future generations, just like his old man, can easily solve problems and invent more useful tools.

Unexpectedly, the current Baigongfang actually calls Jia Fang the "Heir of Luban". Jia Fang is completely embarrassed to the extreme - he really is not!

As soon as the young man who spoke just finished speaking, his master slapped him on the head and reprimanded him: "What are you talking about? Mr. Jia is a noble son of the Duke's Mansion. In fact, a first-class craftsman can than the character."

Jia Fang shook his hands quickly, and said: "No, no, I am also a person, just like you, but I have read a little more than you, and I usually like to do it myself... If you are in my position , I can think of it, it is guaranteed to be more than me..."

Now the craftsmen were all moved and blinded: "Third Master..."

The young master of the Duke's Mansion said that he is the same person as the craftsmen? ——Probably nothing like this has ever happened in the world.

"But the third master came up with so many ideas... Then, at least it was blessed by Lu Ban's ancestor!" Some craftsmen insisted on their own opinions.

Jia Fang: ...Okay!Just gave me this opportunity to spread the word.

"Everyone, I can come up with so many ideas, thanks to this "Theory of Everything", you can see that although it does not directly teach you to make some new objects or tools, but it tries to explain It is the principle of the operation of all things in this world, and if you understand it, I believe that all the difficulties you have encountered in the past may be solved."

"Even if you can't solve it easily, these principles can still provide you with ideas to solve the problem." Jia Fang said loudly, "I dare to assure you that if you thoroughly understand this book, it will definitely be of great help to everyone's craftsmanship—this book will also help you solve problems." It is worthy of being passed down as a family heirloom for future generations."

He spared no effort to bring goods for "The Theory of All Things", and also mentioned his Xiaoxiang Library by the way: "In addition, my family has a large collection of books. Come and ask me. I'll look for it, is there any ancient book mentioned in the family that can be lent to you. "

"Wow--"

"Third Master, is this true?"

"Can we too?"

"To be honest, we don't even know a lot of big characters. Third master, can we understand this book?"

Jia Fang asked with a smile: "Then how do you understand this "Theory of Everything"?"

The craftsmen looked at me and I looked at you, and suddenly laughed together.Someone said loudly: "Go to the next door and get Mr. Dong Hong to read us word by word. Where we don't understand, that person doesn't understand either, saying that he has never read such a bible in his life—"

Jia Fang imagined it for a while: Mr. Dong Hen... This picture is very impressive!

"Later, I was still a young man in the workshop. He knew a few words, and he and that gentleman combined together to explain the words in the book to us in vernacular." The old boy explained to Jia Fang, "We heard it, but we don't remember it very well. But everyone has their own way - as for my old boy, I draw ghost symbols that no one else knows..."

Everyone laughed together again.

Jia Fang also laughed, looked at the old boy and said, "Come on, if one day you can read and write down all your skills, just tell me and I will publish a book for you!"

Speaking of this, the atmosphere in the hall became even more enthusiastic. Everyone laughed together, and the old boy laughed like a fool. He probably never dreamed that someone would promise to help him "publish a book" one day...

But Jia Fang does have this heart.Various technologies in ancient China were mostly handed down from generation to generation by craftsmen in the form of dictation and copybooks. There were very few special books compiled by craftsmen themselves. This also led to a lack of technology flow between regions and technological iterations period is relatively long.

Very well, this matter can really be discussed.

Unexpectedly, the shopkeeper Ren squeezed in at this time, and when he saw Jia Fang, it was as if he had seen Bao, and said loudly: "Everyone, don't pester the third master, I have a very important thing to ask the third master—"

"Third Master, look at you. It's so easy for you to come here, but these craftsmen always pester you with irrelevant questions." Shopkeeper Ren apologized to Jia Fang.

"It's okay, I'm happy." Jia Fang's answer was in the hands of the craftsmen, and all the craftsmen in the room were laughing and applauding, and the shopkeeper's face was flushed with ridicule.

"That's all," Jia Fang hurriedly smoothed things over, "Old Ren, tell me, what is so important?"

Shopkeeper Ren hurriedly called for someone: "Bring the sand table you made last time."

"Sand table model?" Jia Fang really didn't think of this. He always thought that even if there were sand tables in ancient times, they were mainly used for military purposes.But his father Jia Daishan had never seen such a thing, so he naturally thought there was none.

As a result, Baigongfang took out one piece.

Jia Fang saw that it was a model of a port wharf, and it was done very finely—painted a piece of water with blue paint, next to the water surface was a pile of sand to create land, and straw and cardboard were used to make trestle piers and merchant ships.

The entire model is well-proportioned and well-crafted. Jia Fang is very familiar with this craft of making models.

But the most noteworthy thing about the whole model is not the delicate handwork, but the two shining copper rails on the pier.There is also a small carriage model placed on the copper rail.

When shopkeeper Ren saw Jia Fang looking carefully at the copper rail and carriage, his expression was very nervous and he almost held his breath.

But Jia Fang didn't show any concern at all. Instead, he smiled and said: "I forgot to remind you that this kind of track is most suitable for placement in docks and mines. It seems that you have realized it yourself." .”

Shopkeeper Ren breathed a sigh of relief, and stretched out his hand to push the carriage model on the copper rail. The model was so delicate that it could move slowly along the copper rail with just a push.

"This copper rail is really useful at the wharf. In the past, it could only hold a car with a hundred stones, but now it is no problem to hold a thousand stones." The shopkeeper Ren asked Jia Fang, "However, the manual labor to unload the goods from the docked ship is very difficult. It still can’t be saved, and it takes a lot of time to transport this truck with thousands of stones of goods back and forth, so the villain wanted to ask the third master if there is any other way.”

"Of course there is a solution!" Jia Fang said, "Monorail transportation is naturally time-consuming, but as long as another track is built next to the monorail, this problem can be solved immediately."

Jia Fang casually picked up two straws from the table to act as copper rails, and placed them on the sand table model.At this moment, many artisans with quick brains have already reacted.

"One track for loading, one track for transporting goods, and loading while transporting goods, without delay."

Jia Fang smiled and said, "There are more complicated methods, and I will explain them to you next time."

"As for unloading from the pier—who asked me about the fixed and movable pulleys just now?"

The coppersmith quickly raised his hand.

"Have the experimental supplies been brought?"

The other side agreed repeatedly.

"Let's go, let's do the experiment first. Old Ren, don't think that I'm wasting my time in vain. If you know what's going on, you have to know why." Jia Fang explained loudly to the shopkeeper, "Besides, who of you , go and help me prepare a set of ironing tools."

"Hot?"

"Mr. Jia even knows how to cook?"

"It seems that he not only knows it, but he must also be able to get started. In my opinion, it should be said that he is 'proficient'."

"Tsk tsk tsk, this is amazing. The third master is young, he knows everything, and he can do it by himself. This, this... This is not the reincarnation of the patriarch, who could it be?"

"That's right, Su Hui brought from my previous life."

The so-called ironing model is the three-dimensional model of the building. Because the ancient Chinese buildings, especially the imperial buildings, must be presented to the imperial court, the model is specially made. Because ironing is required in the production process, it is called the ironing model.

It is also because Jia Fang has studied ancient Chinese architecture for a while that he is very familiar with the craft of "hot sample".

In the yard of Baigongfang, he explained to a group of craftsmen the principles and differences between fixed pulleys and movable pulleys, and guided the craftsmen to assemble a set of pulleys on the spot.

After that, he reminded the craftsmen how to apply the principle of leverage described in the "Theory of Everything" in practice.

After that, Jia Fang returned to the hall with the craftsmen in a hurry. At this time, all the "ironing sample" tools were prepared and placed on the table for Jia Fang.

Jia Fang quickly made a frame out of sorghum straw and glued it together with paste.Then he cut out shapes out of paper, representing the pulley block, and mounted on that frame.

Shopkeeper Ren and the craftsmen were all waiting for his explanation: "Third Master, what is this?"

Jia Fang smiled: "This is called a 'crane'..."

Around AD, the Roman designer Vitruvius already mentioned the design of hoisting machinery in his "Ten Books on Architecture";

In the 15th century, the Italians invented the jib crane, which greatly simplified the operation of the lifting machinery;

In the 18th century, the invention of the steam engine provided new power for lifting machinery. In the 19th century, steam-powered cranes appeared in Britain...

Now Jia Fang doesn't know what kind of era he is in in this time and space.But why not start now, and regard today, now, and the present as the starting point?

Jia Fang explained to the craftsmen the structural points of the jib crane, gantry crane and bridge crane, but the specific ironing model was only made of the jib type, and the others were just inspiration and guidance. These artisans think for themselves while practicing.

But even so, after he finished speaking, the craftsmen in the room had already admired Jia Fang, and someone proposed to pay homage to Jia Fang: "I regard you as our patriarch in my heart."

Jia Fang: ...This is impossible!

Fortunately, shopkeeper Ren helped him out, and the shopkeeper kindly reminded Jia Fang: "Third Master, you came to our place today, is there something important?"

Jia Fang slapped the back of his head suddenly: "There is something important, I almost forgot if I didn't mention it."
