The vast majority of Chu people do not understand what a system is, let alone the importance of a system. Only those people of insight can understand how powerful this art is, in Dachu, it is usually not called a system, it is called inheritance.

What is Heritage?

To put it in layman's terms, it is the craft, knowledge, and the ability to survive. Passing on the son but not the daughter, this is aimed at inheritance, translated into modern language, that is, a certain aspect of systematic knowledge.

The emperor's house is called the emperor's study, the merchant is called the business economy, and the craftsman is called the unique secret book. Even those who sell coolies have their own ways of surviving and working, and this thing is the system.

If there is no complete system for any line of work in Da Chu, it is the secret master. What the secret master learned was obtained from the secretary in ancient times, and the words on the secretary were unreadable, and so far, all the secret masters have recognized that there are only two words that are correctly translated: Xuanmen.

There are many other texts that have been circulated, but each has its own solution, and the difference between one word is a thousand miles away. There are too many differences between different interpretations, and there are also different schools of thought for the same secret masters.

It's just that the number of secret masters is too small, and compared to an empire like Great Chu, even if the number of secret masters is ten times more, there won't be much strife. Only when the number of secret masters is so large that Da Chu can't afford to support it, and it is necessary to choose between secret masters, will there be disputes between the schools and doctrines of secret masters.

Luo Ning, at the age of ten, was already on business, interpersonal relations, economics and other business-related knowledge, no teacher, summed up a set of systems by herself, it is with the help of this system, she can use five years to push the family to today's height.

The more Mozi talks, the faster he talks, all the things he usually uses, basically he doesn't need to think about it, he just opens his mouth, and when he talks about silk rice, humi, and micron, Luo Ning's whole person is not good.

If Mozi had talked about these units at the beginning, she would only have treated Mozi as talking nonsense, but people systematically spit out a series of various weights and measures, and she couldn't help but believe it.

"Wait a minute, how long is a millimeter?" Luo Ning asked, meters, centimeters, these two units, she can barely accept, to the level of millimeters, it is difficult for ordinary people to quantify it through thinking.

"It's so long. "It's easy to do, Mozi pulled out a metal ruler from his waist, for Mozi, this is his business for eating, he carries it with him, and he will put it under the pillow when he sleeps at night.

This is a metal ruler with a millimeter scale, and in order to make this thing, Zhang Tan did not put a lot of effort into it.

Looking at the clear scale on it, Luo Ning's face was gloomy and terrifying, he could still be treated as nonsense before, but seeing this metal ruler, Luo Ning couldn't believe it or not.

The industry and commerce of Da Chu are not separated, businessmen need to transport goods, and the workshop is the source of manufacturing goods, so big merchants must be the owners of the workshop, under the name of the Luo family, there are tens of thousands of people working in the workshop, and these are all built by Luo Ning, she is a connoisseur, and she knows at a glance how high the technical content of this metal ruler is.

Not to mention how the Shengong Temple engraved such a clear scale on the metal, just the material of this metal ruler, the blacksmith workshop under the name of the Luo family, will definitely not be able to create it, this art is sharpened, it is much sharper than an ordinary knife.

"Ten millimeters in a millimeter?"

"Yes. Interrupted by Luo Ning, Mozi, who had spoken very smoothly, was stuck, recalling, even he couldn't remember what he just said, it seemed to be quite familiar knowledge.

Holding a metal ruler, I carefully stared at the smallest scale on it for a while, if it was carved by hand by the best master in the house, it was not completely impossible, but the accuracy would definitely be affected.

As for the smaller so-called Humi, Luo Ning intuitively thought that Mozi had been fooled, he must have been deceived by Renault, such a small length has exceeded the limit of human eyesight, it is impossible to depict it, and there is not such a thin iron pen.

"Oh, smaller units, you can't use this kind of ruler. Measuring silk rice, you need vernier calipers, smaller units, it is still difficult to measure at present, Mr. said, now to silk rice is barely enough. As he spoke, he pulled out a vernier caliper from his waist.

This is also the finest length gauge that Renault can make at present, and he also understands the principle of a spiral micrometer, but the current manufacturing accuracy is not enough, and the measurement effect is not successful, so it has not been popularized.

How simple the vernier caliper is, he prefaced it in front of the chapter altar, and got the sample the next day. The craftsmanship of Zhangtan is actually far better than that of the fifth-level fitter, and the millimeter-level unit will not make a mistake when people touch it with their hands.

Mozi was very shy and didn't dare to look directly at the girl, but when it came to vernier calipers, he didn't care that Luo Ning was also a beauty, so he took the paperweight on Mr.'s table, sandwiched it into the caliper, and taught Luo Ning how to use it.

The use of vernier calipers is very simple, a smart person like Luo Ning, as soon as he learns it, measures a few things, and then he can't put it down, thinking about where this tool can be used.

"Mozi, you take Miss Luo to the craftsman camp for a walk, what you should say, if you don't know how to record it, wait for me to explain it to you when I have time. Renault looked at this pair of villains very interestingly, and his pure heart gave Mozi more opportunities.

secretly said in his heart, a young man like Mozi, placed on the earth, is destined to become a single dog in scientific research, even if he can become a master in a certain field, what people want is his status and money.

Renaud himself doesn't know much about love, four years of college, and little experience in this area is pitiful, but after all, he has seen a lot, like Mozi, who is unknowledgeable and wooden, I'm afraid he really can't get a wife.

Da Chu is good, this is a world where you look at your identity first, Mozi is regarded as his personal disciple of Renault, even if he is ugly as a pig, there are a lot of beauties upside down, not to mention that Mozi is not ugly.

Send the two of them away, and find a plan from the rattan box, this literacy plan was completed, and it was written before it arrived in Dingjun City, and it has been packed in the box to eat ashes. There's no way, the low literacy rate in the Dachu world makes people speechless, and the Shengong Temple team has a total of one hundred and ten literate people, and they are all of great use, where is the time to eradicate illiteracy for everyone?

This time, Cui Qing brought back nearly 400 literate bachelors, in a short period of time, they couldn't help, just while being a teacher, while learning the working methods of the Shengong Palace, if you want to really integrate into the Shengong Palace, it will take at least a few months, and the speed will be faster, so that most people can know hundreds of words.

The enthusiasm of the people of Dachu for learning is incomprehensible to the people of the earth. Learning, in Dachu, can be eaten as food and spent as money. It is difficult for ordinary people to find learning opportunities, and those who can become apprentices are the best of the best, and ordinary people are only worthy of selling coolies.

The ground of the Iron City has been partially built, but Renault's plan has also been changed beyond recognition.

Originally, Renault was unhappy, but when Zhang Tan took his disciples and pulled a so-called iron plate ten centimeters thick with a car, Renault knew that he was taking it for granted again.

In his mind, ten centimeters is one hundred millimeters, which is really not thick, and a slightly better suspension tank armor will not be less than this thickness, and it is made of modern alloys, converted into ordinary carbon steel smelted by Renault, which is hundreds or thousands of times stronger, equivalent to tens of meters, or even hundreds of meters thick carbon steel.

The problem is, this is Da Chu, and when he saw with his own eyes something half a student's ruler thick, he had to admit that it was more appropriate to call it an iron block than an iron plate.

Renault was as good as a stream, and with a wave of his hand, the thickness was halved. Although he didn't achieve the result he wanted, Zhang Tan was still very happy. The thickness is halved, which is equivalent to halving the amount used, doubling the area, and his burden is much lighter all of a sudden.

With the first piece of 1,000 square meters of fine iron foundation, Zhang Tan immediately began to build a new blast furnace, directly on the first furnace, and when the construction was completed, it was found that the first furnace was not enough, and the second blast furnace, on the basis of the first furnace, doubled.

Is furnace number one big?

In Dachu, it is naturally very large, producing 4,000 catties of refined iron at a time, which is two tons. With one furnace, five square meters of fine iron foundation can be laid.

You must know that after there is orange coke, at least five furnaces or even six furnaces can be produced in a day, and an area of nearly 30 square meters can be paved.

This is just a blast furnace, and in a few months, nearly 100 No. 3 furnaces have been started in the rainforest at the same time, otherwise such a large area would not have been paved.

How much is two tons of molten iron, just think about the density of iron, it is only a quarter of a cubic meter, if ordinary people have larger buckets, it is only a few buckets, this is already the No. 1 blast furnace.

Da Chu's smelting is even worse, because the technology is not up to par, there are too many impurities, the smelting furnace is larger, but the output is amazingly low, the most infuriating thing is that it is iron that comes out, you still have to look at luck, if it is not good, you have to return to the furnace.

The fine iron foundation uses the melt welding method, which is the most primitive welding method. The technology was insufficient, there was no equipment, and Renault couldn't think of a good way.

The so-called molten welding is to first lay a square of standard fine iron plate, leave a gap in the middle, first heat the edge to a soft state with orange coke, and then use red-hot fine iron to pour spoons into the gap.

One person in front of him pours it with a spoon, and two people have to follow him behind, one is responsible for heating, and the other is holding a scraper, constantly scraping it flat to ensure that after welding, the surface of the fine iron plate is basically flat.

Although it is very primitive and the efficiency is also very low, Renault has been to see it, and the effect is not bad, anyway, there will be no heavy trucks running on it, it will not be damaged easily, and it is easy to repair if it is broken, and it will be finished with a spoonful of molten iron.

Even if Renault provided a variety of equipment and tools, as well as the most advanced technological process of Dachu, as the project was fully rolled out, more and more blast furnaces were built, and manpower began to be tightened, not to mention the coolie battalion, and even the escort team began to reduce the number of people and join the engineering army.

Personnel are still living in the rainforest for the time being, seeing that the output of fine iron plates continues to increase, the people who originally thought that Mr. was crazy became suspicious, according to Mozi's calculations, with today's production increase rate, it is not easy to build a large fine iron city, and it will not take too long to accommodate the fine iron city of the Shengong Temple.
