The strong servant hurried back with a hundred silver dollars, and Sun Yuanhua bought a large map of the Ming Dynasty. Before leaving, he flipped through all the books sold in the reading room, and felt pain.

These books are sold publicly, and although they are expensive, they are not deceitful. According to the old woman, the south has developed commerce and sufficient capital, and the officials and gentry have a desire for profit. Many people came to Tianjin to do business, and soon found that all kinds of short-term and fast-paced basic industrial projects were sold here. Not long after the books were sold, there were pirated copies in Jiangnan.

Most of these books deal with how to produce and process raw materials, such as ironmaking, which is an obvious science that can easily make people rich. The iron-making industry in Foshan, Guangdong Province is very developed, but only iron products are sold, but the iron-making technology is strictly kept secret. Others can't learn if they want to, but the 'revolutionary army' is open to selling knowledge at a very low price.

The book "Ironmaking by Soil Law" teaches people how to beneficiate, how to build a blast furnace, how to use animal power or even water power to push the blower to increase the furnace temperature, how to choose fuel to reduce impurities, and describe the problems that will occur in ironmaking one by one. However, the book only says that there will be those problems, but how to solve them, but does not say anything, and only allows people to go to the technical school of the 'revolutionary army' to study.

After Sun Yuanhua bought the map, he suddenly felt that it was too little for him to bring more than 100 taels of silver. He wanted to buy all the books in the old woman's hand in the reading room, but in the end he only bought one more copy of "Ironmaking by the Earth Law".

Back at the inn, Sun Yuanhua immediately asked people to send the purchased map to his teacher Xu Guangqi. At the same time, he recounted that the 'revolutionary army' sold a large number of various practical books in Tianjin, and asked the teacher to send some more money.

For the book "Soil Law Iron Smelting", Sun Yuanhua stayed awake all night. He immediately discovered that the industrial drawing technology of the 'revolutionary army' had made a huge breakthrough, and all the drawings in the book were drawn according to certain standards, and the proportions, dimensions, and perspectives were all specified. This is very different from the way the pictures are like landscape paintings in the Ming books.

"It's a great way to make a cartograph, and you can see the details at a glance. It's just that many places are also puzzling, and you must find a detailed explanation of this cartography before you can understand it. Sun Yuanhua relied on his smart brain to read the engineering drawings in the books as if he didn't understand it, constantly scratching his ears and cheeks, excited and angry.

The name of this book is Tufa, but many places are already the most advanced technology in the world, and it was excerpted and proofread by Shi Stone, the Minister of Mining in charge of iron and steel smelting of the 'Revolutionary Army'. In terms of content, it is extremely solid and very operable - the premise is that you must first learn some pre-knowledge of engineering and machinery, otherwise you will be blind and peep into the leopard.

After reading all night until dawn, the brocade agent in the inn brought Sun Yuanhua hot water and breakfast for washing. Seeing that he was flipping through "Soil Law Iron Smelting", he couldn't help but persuade: "Lord Sun, it's useless for you to read this book." ”

"Nonsense." Sun Yuanhua was not happy, he was an expert in smelting and casting, and he could see at a glance whether this book was useful or not, "The person who wrote this book is quite talented, and he has a deep understanding of ore and ironmaking. Many of the methods in the book are thought-provoking, and the drawings are extremely well-drawn, making it an absolutely amazing book. I learned this book, and it will be of great use to my court. ”

The Jinyi secret agent still shook his head and said: "My subordinates also know that this book is good, but because this book is so good, there are many people who are fooled." ”

"Oh......, what do you mean by that?" Sun Yuanhua was puzzled.

"Recently, many officials and gentry in Jiangnan have begged us for Jinyiwei, asking us to explore the key to the many secret techniques of this anti-thief. In particular, I asked if I could dig up a few craftsmen to go, even if it was to tie up tickets. After careful questioning, the subordinates learned that most of them valued the benefits of this iron tool and wanted to engage in this blast furnace ironmaking.

It's just that this book is good, but it's also too good. The anti-thief soldiers are strong and strong, and they must have a secret technique on the road of smelting. But the methods used in this book are so difficult to build that I can't even read the drawings. Some people have spent thousands of taels of silver trying to build it, but it is always not critical, and the quality of the iron smelted is not very good. If you want to know the essence, you have to find an anti-thief craftsman to teach it by hand. ”

Yes......

Sun Yuanhua exclaimed after hearing this, "I just said that this 'revolutionary army' is not so kind, how can this militaristic secret art be easily taught?" ”

"Not really." The brocade-clothed spy said again: "This book says that if you want to learn, you should send someone to the school of the thief to learn. It's just that to learn the essence of it, you must be recognized by the thief. For example, in Tongling, Anhui Province, and Dexing, Jiangxi Province, some people have learned the technology of copper mining and efficient smelting, on the condition that all the copper ingots produced by them are sold to the thieves.

In addition, many cloth merchants and salt merchants in the south of the Yangtze River forbade the goods of the anti-thieves to go south, and the anti-thieves could only negotiate with them. They traded these techniques such as iron-making for the support of southern merchants, who told them to give up weaving and specialize in growing cotton. In the same way, they bought cotton openly and increased their purchases of southern production, ensuring that southern merchants made a profit.

The thieves even openly publicized the matter in the newspapers, saying that this is a kind of business complementarity and win-win cooperation. Although the cloth merchants and salt merchants in Songjiang and Yangzhou are opposed, more people have been poured a belly of ** soup, and they have been moved by the words. There are many profit-seeking people in this world, knowing that the thieves hate the gentry, and there are even officials and gentry who are willing to seek skin with the tiger, I really don't know whether to live or die. ”

The 'revolutionary army' has clever methods in domestic and foreign affairs, and Sun Yuanhua has become accustomed to it. All he cared about now was whether he could learn the art of ironmaking. Knowing that the 'Revolutionary Army' had not completely closed the door to technology, he asked again how he could work with it.

The Jinyi spy thought for a while and said, "Didn't Lord Sun always want to see the anti-thief's agricultural machinery?" Why don't you go to see its demonstration farm and pretend to want to buy and sell its agricultural machinery. As long as you get in touch with the thief, you may be able to gain trust and learn their secret skills one day. ”

Sun Yuanhua nodded slightly, "It's okay, it's okay." It seems that I can only make a little maneuver and come back to steal the teacher. I happen to be free today, so I'm going to take a look at the demonstration farm outside the city. "He said he would do it, and he hurried out of the house without sleeping all night, and took a bus and a horse-drawn carriage to a place called 'Xinguang Farm' outside the city.

It's the end of May now, and the planting of rice has long been over. However, this is a model farm, a place where the 'revolutionary army' is specially used to publicize its agricultural achievements to outsiders. When Sun Yuanhua arrived here, he saw that all the originally small fields had been opened, and the plot became extremely large and boundless.

There have always been many people who come here to visit, and many people have heard that the 'revolutionary army' has a very good way of farming, and they even come from thousands of miles to see it. Sun Yuanhua is an inconspicuous person in the flow of people, and when he arrived here, he found that there was a special docent here, and he was still a woman.

"Master, I heard that when the thieves built the farm, they killed a wave of people." The strong servant followed behind Sun Yuanhua and said in a low voice, "Originally, there were too many fields and it was inconvenient for large-scale cultivation, so I merged small fields. For this reason, many graves in the field were leveled, and many of the original Zhuangzi were relocated, just to get this large field in front of them. ”

"And moved someone else's ancestral grave?" Sun Yuanhua was shocked.

The strong servant nodded, "What is it to change customs, in the future, people will be cremated when they die, and they can no longer be buried." It is said that burials occupy too much fertile land. Sir, do you say this is not fucked up? This thief has lost his conscience, and he can't do it if he wants to go to the ground for peace when he dies. The bones of many people's ancestors have turned to ashes, and there are many people who are desperate for this. But it didn't work, and they all had to die when the fire cracked. ”

Sun Yuanhua shook his head again and again when he heard this, "I really don't know what to say about this 'revolutionary army'. If you want to say that they love the people, the benevolence and righteousness of this handsome man are unparalleled in the world. But they can do anything under the ferocity, and the knives are really sharp, and they don't recognize their relatives at all. ”

After living in Tianjin for so many days, Sun Yuanhua felt very deeply. From hatred at the beginning, to admiration, to astonishment, he finally found that this 'revolutionary army' actually didn't care much about what the people at the bottom thought. According to the joke - the common people just do their own thing, don't take themselves too seriously. It's you who can't do without the handsome, and it's not the handsome who can't do without you.

This is really true, and Sun Yuanhua can't refute it. He walked slowly with the visitors, listening to the farmer's docent. If you take a closer look, the farm is really well built, the fields are unconventional, and there are many types of demonstration crops. Wheat is grown in dryland, and rice is grown in paddy fields. In addition, some of the poor fields are planted with sweet potatoes and peanuts, and even vegetables and pastures.

Most of the visitors came for the rice transplanters and seeders, so there were a few fields for demonstrations. When the rice transplanter was moved out, Sun Yuanhua squeezed in front of the person on tiptoe - a hand-cranked manpower rice transplanter, which was originally driven by a chain. But the 'revolutionary army' could not make a chain at the moment, so it simply rolled it with a belt.

The docent puts some of the weeds into the rice transplanter and pushes the machine around the field while shaking the handle. I saw that the belt drove the two groups of toggle mechanisms to move flexibly, and easily grabbed a row of weeds that were laid flat and inserted them into the paddy field. The weeds are evenly spaced and the lines are straight, and the point is that this is really too effortless.

Although he has heard of his name for a long time, Sun Yuanhua was still shocked when he really saw it. As long as the seedlings are lined up and put into the rice transplanter, there is no need to bend over, do not bow your head, gently push the machine forward, turn the handle to plant the rice seedlings - this is too easy.

There was an uproar at the scene, and many of them asked loudly about the price of the rice transplanter, asking to buy it back out of their pockets. Sun Yuanhua's brain was buzzing even more - with this thing, one person is worth ten people. The commentator also said that the 'revolutionary army' not only made a rice transplanter in this paddy field, a sowing machine in a dry field, and even a harvester with animal power.

Sun Yuanhua couldn't help it, and asked in surprise: "Even harvesting can be done with a machine?" ”

The answer, of course, is yes.

Sun Yuanhua suddenly felt that his eyes were dark, and he almost fainted - I am based on farming and reading, but now I can't read and read others, and I can't even farm land, how can I lag behind this? Hundreds of years of accumulation are not comparable to a gang of thieves.

At this moment, the narrator suddenly exclaimed: "Dashuai, our Dashuai is here." ”

The name of the marshal of the 'revolutionary army' is like thunder, and who in the world does not want to see it? Even Sun Yuanhua immediately turned his head and looked around, wanting to see what the leader of this terrible force looked like.

And on the way into the farm, dozens of guards were pulling out the cordon, politely but unquestionably, 'Please give way'. Sun Yuanhua was also pushed aside, and saw a young teenager walking with two men in their thirties.

The young man was still vigorously making amends to a man: "Mr. Chang Geng, don't be angry." My bad, my bad. I shouldn't have had your whole family tied up and frightened my husband. But I really admire his talent, and I want to ask him for help. Seeing you today, I will definitely make my husband's trip worthwhile. ”

The young man turned his head to look at a tall blonde maid behind him, and scolded loudly: "Look at the good things you have done, I asked you to invite Mr. Song here." You kidnapped the whole family, and you also wiped out all the relatives and friends, as well as the teachers and classmates, which is hundreds of people. You ran away for so long and didn't come back, and I was worried about whether you were harmed by some bad guy. ”

The man who was apologized looked angry, but he was helpless. He saw the young man reprimanding the maid, and couldn't help but sneer at him: "You maid is very skilled, who can harm him?" Our whole family was almost scared to death by her. ”

The young man suddenly came to play again, "Mr. Song, forgive the sin, forgive the sin." You see you're here, you have to open your eyes. I happen to have an artifact here, which Mr. Custodian hasn't seen before. ”

"I saw your rice transplanter yesterday. It's just a bit clever, and it's not a great thing. Song has already understood the trick, and in time, I can make it myself. The man was still not angry, angry that his whole family had been kidnapped.

"Sir is really talented, but this thing to see today is not ordinary." The young man shouted loudly, "If you make a bet with me, sir, if this thing can be understood by him today and made it himself, I will let him come and go freely." But if I can't understand the principle, can you help me? ”

What is it?
