The layout of the yellow yellow workshop next door is similar to the engraving workshop that has just been determined by Zhu Yuan's new name, and not all of them are making yellow steel and the like.

In the outer courtyard of the two-fold courtyard, Zhu Yuan entered the door, in addition to the house, the first thing he saw was that there was a furnace for smelting metal in this era on the left and right sides, and the craftsmen inside and outside the house were busy with various processes, such as scraping, blowing, turning sand, casting, forging, quenching, etc.

The gears, shafts and other parts other than the mainspring required by the watch engraving workshop, whether made of copper or iron, are preliminarily cast in the outer courtyard here, and then sent to the next door for fine processing.

Even for the production of engraved watch parts, the corresponding process is still relatively ordinary in this era, and Zhu Yuan just walked around and came to the inner courtyard.

When you enter the door here, you will only see a furnace system, a few large and small stoves, closed or open, and, although there are people working, they are obviously not as busy as outside.

Wei also motioned for Zhu Yuan to go to the west wing, and took the initiative to explain the current scene: "My lord, it's not Xiaguan who cherishes himself, Xiaguan began to forge yellow iron with his grandfather at the age of eight...... Well, that's it...... Playing Huanggang, it has been thirty-one years so far, barely succeeding, this craft, my father, uncle, have not been able to learn, the Wei family has only become one of me. Playing yellow steel, from the selection of materials to the heat, there is a difference of one point...... Or it is elastic, but to do that clockwork, but it can't. Even if the lower officials ...... Among the ten furnaces, only two or three furnaces are refined, and then the clockwork is made, and the forging and tempering are inevitably poor, and most of them are abandoned."

Zhu Yuan nodded in approval.

In those days, there was a lack of standard processes and measuring instruments, so it was decided that many crafts depended on the experience of craftsmen.

This is most vividly reflected in the ceramic firing that has been involved before.

Besides, I didn't understand this yellow steel, but I thought about it privately from the fundamental level of my habits, coupled with Wei Ye's introduction, Zhu Yuan understood that if it was simple, it was very simple, but there were two things: "materials" and "heat".

In particular, it is the top yellow steel that can be used to make engraved mainsprings, and the requirements for materials and heat will only become more demanding.

Lack of modern testing tools, lack of accurate temperature monitoring instruments, lack of a variety of clear physical and chemical knowledge as support, all based on experience for smelting and forging, even if each link has a ninety percent success rate, after seven or eight links, the original "0.9", will inevitably be reduced to less than half.

What's more, it can be ninety percent.

As he spoke, he had entered the west chamber, and here was a warehouse, and he turned to the south room, where seven or eight baskets of black ore were placed in baskets.

In this era, ordinary iron ore obviously did not have the current treatment, not only in a house, but also in a basket, the size of the ore inside is also very uniform, obviously carefully selected.

Wei Ye stepped forward and squatted down, grabbed a handful of ores and showed them to Zhu Yuan with a very precious feeling: "Your Excellency, please see, this is the ore needed for the forging of yellow steel, or the care of the adults, so that the lower officials can bring these ores from the capital to Jinling, a total of sixteen baskets when they came, half of them have been used, counting some of the accumulations of the upper and lower officials earlier, fortunately to supply the ten engraved watches."

Zhu Yuan reached out and took a piece of ore, and saw that Wei Ye subconsciously took out a handkerchief from his arms as if he wanted him to pad it, shook his head with a smile, and carefully looked at the dark ore in front of him, which still had some bright colors: "Tell me about reasoning, why this?"

"Why ......" Wei also thought about it and said, "This, the lower officials can't say it well, it's just that since childhood, my grandfather first taught me to choose materials, and I lived in Dadu at that time, and the Wei family had to ...... from the imperial court every year I have selected several times from the ore that has been transported from all over the previous dynasty, and I don't want other yellow ore magnets, but only focus on this one."

Zhu Yuan continued to look at the ore in front of him, thought for a moment, and said, "It should contain some kind of special metal component, I mean, metals other than iron, this ...... Oh, since you even read "The Science of Economics", it means that you are a motivated person, and you just said that you are the only one in your family, which also proves that you are talented. In this way, take the time to study chemistry, this chemistry major involves the secrets of the imperial court, and you can only contact it with the approval of your ancestors in person, you are new from the north, and you are not qualified to study, but I vouch for you once, and I hope you don't let me down."

Wei didn't know what "chemistry" was.

But listening to what Zhu Yuan said solemnly, plus he is indeed a motivated person, in just these short periods, he also discovered the different attitudes of this new dynasty towards craftsmen, and now, how can he not understand his own opportunity, and immediately knelt on the ground: "Wei Ye Xie cultivated, and would rather die than live up to the adult."

"Get up," Zhu Yuan said, "I said, this science involves the secrets of the imperial court, even if you can practice, there are still some deeper things that you can't touch, but even so, if you fail me, you can only die, and even your family will be affected."

Wei didn't rush to get up, and when Zhu Yuan finished speaking, he finally got up after reassuring him.

The people around saw that Wei Ye had another creation in the blink of an eye, and they all looked envious.

Zhu Yuan turned his head and looked at Jin Dahu, Zhao Xu and the other craftsmen and guards who had been accompanying him: "You guys go out first, I'll talk to Lao Wei, heh, he didn't explain it thoroughly just now, and he doesn't want you to hear about his own craftsmanship." You must not listen to what I am going to say next."

Waiting for everyone to go out, Zhu Yuan sat on the stool that Wei Ye brought from outside, still holding the ore sample in his hand, thought about it again, and said: "Everything in heaven and earth, whether it is the air we breathe or the soil under our feet, is composed of elements, which is the root of chemistry, and the elements can be divided into metallic elements and non-metallic elements, which are arranged according to their most fundamental atomic weight that is only one billionth in size compared with rice grains, that is, the so-called "periodic table", this table, oh, more than 100 elements in the world, I only memorized the first two dozen or so, namely "hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxyfluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chloride, argon, potassium and calcium" and "iron, cobalt, nickel, copper, zinc" after skipping five."

Speaking of this, Zhu Yuan turned to Wei Ye, who was listening carefully: "In this periodic table, how many familiar ones have you noticed?"

Wei also pondered a little and said, "There is 'charcoal', there is 'sulfur', there is 'iron', there is 'copper', and there is 'zinc', which used to be called 'Japanese lead'.

Zhu Yuan listened to what Wei Ye said, and he also recalled it, and said with a smile: "You are very powerful, you have grasped all the key points, and you can know "zinc" in such a short time, you are really a caring person, well, how old are you this year?"

"My lord, the lower officials are ashamed to spend 39 years in vain."

"39 years old, not big, in addition, too modest this problem has also been changed," Zhu Yuan said, "You are capable, understanding, willing to be attentive, willing to be motivated, and still in the prime of life, and your potential is far from just a manager of the Yellow Workshop now, and ...... in the future. Oh, if you have a good creation, you can't be worse than the Ministry of Works."

Wei Ye was subconsciously and modest: "My lord, the Ministry of Industry is still ...... I can't imagine that day."

"Indeed, whether you can be a person or not depends on fate, but whether it is the ancestor or me, I like people like you who are capable and willing to make progress, well, let's not say more, I am not in good health, I feel tired again, and I will talk about ores," Zhu Yuan turned to the black and bright stone in front of him: "This thing, do you think there is anything special?"

"If it's a special ......," Wei Ye still couldn't help but hesitate before he said, "The bullet yellow steel made from this ore ...... Such as...... Not easy to rust."

"Stainless steel," Zhu Yuan said, "that should be nickel, an alloy composed of nickel and iron, with stainless properties, the so-called rust of iron, is to react with oxygen in the air to form iron oxide, that is, the iron ore in our hands, but, well, remember, there are many types of iron oxides, ferric oxide is red, iron tetroxide is black, the ore in our hands, black, among which the oxide of iron, is ferric oxide. The process of ironmaking is a reduction process in which the "oxygen" element of iron oxide is removed with the element "carbon" and other auxiliaries, and the element is reduced back to iron alone, well...... I talked a lot about it, and in short, you'll learn all about it later."

Not much, not more!

Wei Ye, who felt that the door of a new world was opening to him, was almost subconsciously about to speak, but Wei also knew that the young man in front of him was so noble and in poor health, in case he was tired of these studies with himself, he could not afford this crime.

He could only suppress the curiosity in his heart, and bowed sincerely and nodded: "The words of the adults have also benefited a lot."

Well......

Zhu Yuan felt a certain déjà vu, but it was okay

This time I didn't meet the "saint" again.

In the past two days, the more Zhu Yuan thought about this matter, the more ashamed he felt.

All kinds of learning at the middle school level were sanctified.

So he turned back to the iron ore in front of him, and couldn't help but say one more sentence: "Let's talk about steel and iron, do you know the definition of steel?"

Wei also thought for a moment and said cautiously, "Tempered into steel?"

"This is a literary description, completely unscientific," Zhu said with a smile, "The one I know, steel, is clearly defined, and iron with a carbon content of between 0.02% and 2% can be called "steel". Percentage, I guess someone like you is so studious, you should already know it?"

Wei also memorized the concept given by Zhu Yuan, and when he heard the last question, he subconsciously showed a look of shame again: "The lower official also read the adult's "Mathematical Foundation" in private."

Zhu Yuan nodded and asked with a smile, "What about the Sketching Technique?"

"I also see it," Wei didn't hide it, and added frankly: "It's just that the lower officials have less talent for painting."

"Just be able to draw drawings, this will be very important in the future, and you can ask the Great Protector for advice privately." Zhu Yuan said, and played again: "Just understand a little."

"Remember."

"Finally, let's talk about the process of playing yellow steel," Zhu Yuan said: "I think you must know that this yellow steel can not only be used for simple engraved watch springs, but also can be used to make weapons, as well as various mechanical parts, the future will be the "industrial age", the representative of the "industrial age", that is, machinery, among the machinery, the indispensable is to play yellow steel, so, are you willing to let go of your craft and help the imperial court cultivate corresponding talents in large quantities?"

Wei also did not hesitate: "Xia Guan is willing."

Zhu Yuan was surprised, and asked with a smile, "So simple...... I know that if the family heirloom of this era is leaked to outsiders, it may be a great rebellion that can't even enter the ancestral grave?"

"Because Xia Guan can figure it out," Wei also laughed, "Even if Xia Guan doesn't give it up, the adults know the reason, and they can find someone else to make this yellow steel, but it will take more time." When the time comes, the craftsmanship of the lower officials will become chicken ribs. Therefore, if the lower officials do this, they will not blame the ancestors."

"You really understand people," Zhu Yuan said, "Actually, the essence of playing yellow steel is not so profound, and even, I think, your family's attachment to this kind of nickel-containing ore has become your limitation. Bullet Yellow Steel ...... I think the composition of the alloy may be a problem, but if we're going to produce it in large quantities, and it's not so high, it's just a matter of process, how to temper, how to quench, and so on, to finally get the rebound characteristics of the steel. This is more inclined to the change of physical characteristics, just like steaming steamed buns, making raw noodles into mature noodles, if I want a certain taste and a certain shape, as long as people do it, and I can mobilize a lot of people, there will always be people who reach the goal, the goal is achieved, summarize the experience, and immediately teach a large number of people. Compared with your small-scale workshop production thinking, large-scale mass production, this is industrialization that can bring us into the industrial age."

Wei also nodded again and again, feeling that he was starting to be a little unable to remember, and some of the expositions also made him seem to understand.

I'd love to find pen and paper.

Zhu Yuan just played casually, and after saying this, he threw the ore in his hand again: "Is this nickel-containing, when the time comes, you can also study it together, about this, metal oxides can be dissolved in acid, and the acid solutions of different metals are also different in color, as for how to separate iron and nickel, I know a displacement reaction, however, the distance between iron and nickel in the periodic table is too close, um...... When you think about it, iron and copper are also close, in short, try it yourself. Again, as I said, iron-nickel alloys, the best property is stainless steel, and think about how versatile it would be if steel could remain stainless steel."

Of course, Wei can imagine it, and he still thinks ...... It's incredible.

Zhu Yuan felt really tired, so he didn't say more, got up and went out, and listened to Wei also roughly introduce the forging process of playing yellow steel...... In fact, it's not abandoned, it can't be made into clockwork, but it's also on

Good steel, I can't help but remember another thought that I have been thinking about.

"These...... Draw it into silk and make it into a two-inch yellow with a diameter and a length of three inches, and make one or two hundred, is that okay?"

Wei was also listening, not knowing why: "My lord, what is the specific purpose?"

"Sofa, mattress, this kind of thing," Zhu Yuan saw that Wei Ye was still puzzled, and gestured with a smile: "Just make a mattress, the length and width are one zhang, the middle is stuffed with elastic yellow, and both sides are covered with coarse cloth or leather, and it will be very soft and comfortable to sleep on it."

Wei also understood, and said decisively, "My lord, give the lower official three days."

"Don't be in a hurry, don't delay the business, just use these corners for the material." After Zhu Yuan said this, he continued: "In addition to mattresses, you can also make sofas, which are big chairs with similar methods, which will not be limited to me alone, and can be made into an industry in the future, whether it is a mattress or a sofa, it can be sold for a very high price, and you can also make a profit from it."

Wei also knew that the young man in front of him, Pingzhang, was a person who was very interested in businessmen's affairs, and he was not surprised to hear Zhu Yuan speak, but he just agreed seriously.

Leaving the two adjacent workshops, more than half an hour has passed.

Approaching Shenzheng.

It was about four o'clock in the afternoon.

When I walked out of the courtyard gate of the Danhuang workshop, I don't know if it was because there was no wind, or if the kiln happened to start burning nearby, and the air was filled with a surging smell of fireworks.

In order to accommodate the craftsmen who came from the capital, as well as the construction of several universities, there were at least 100 brick kilns of various colors from the north of Xuanwu Lake to the vicinity of the Shogunate Mountain, and the bricks and tiles were burned all the time.

This area originally belonged to the mountainous and hilly terrain on the outskirts of Jinling, Zhu Yuan looked up at the smoke visible to the naked eye in the air, but he thought that after the completion of this infrastructure construction that was not small in this era, it is estimated that the surrounding area will become a plain, not to mention hills, and many mountains may no longer exist.

Also, the environmental protection issue is indeed time to pay attention.

Entering the sedan chair, a certain sack waited quietly in it, helped Zhu Yuan to sit down, and Nizi approached and pasted it, so that her adults could hold herself as a pillow.

Zhu Yuan didn't do this, he pushed, and the girl retreated slightly, wanting to kneel at his feet.

Zhu Yuan grabbed it again, just got up the sedan chair, but Lin Xiaoyu's body was only a little upside down, so he easily stood firm, and let his adult hold his soft waist wrapped in thick clothes, his eyes were bright, and he was inquiring.

After the sedan chair was stable, Zhu Yuan pulled Nizi in some more, kissed the little mouth, looked at the girl's blushing face, and teased her, "Say something, I'll kiss you again."

Lin Xiaoyu obediently opened his mouth twice, not even making a sound, obviously pretending.

Zhu Yuan laughed: "It's too perfunctory."

But I couldn't help but kiss it again, the girl's body was fragrant, coupled with that clear face, it really made people want to bully, and Lin Xiaoyu was also very obedient to let his own adults "bully".

After kissing for the second time, he didn't continue, but just hugged the girl in his arms and asked, "Will it feel boring?"

Lin Xiaoyu blinked.

The adults are saying strange things again.

In the Pingzhang mansion, except for occasionally accompanying his own adults to go out, the other ...... Just count her freedom.

Himself, but the fifth.

Zhu Yuan understood the girl's little expression of "adults are moaning without illness again", and felt that she had nothing to do, she was really bored, but this was also unbearable, so she glanced down at the girl: "You are not as big as Zhongli."

Lin Xiaoyu laughed again, and gently took the initiative to stick his body forward, and left with a little water.

Zhu Yuan understood again.

The girl said that she still prefers her.

That's narcissism.

Adult, I am such an obsessed with women, how can I be bound by a little girl, so I punished and raised my hand to give a slap of five cents.

Pity......

Not only did he lose his strength, but he also made Nizi laugh.

Zhu Yuan also laughed, laughed until he was annoyed and angry, grabbed the girl, and left her chin

A shallow tooth mark, look at you are still proud!

Wait to go back and be cleaned up by the jealous blank.

The girl also understood, but she was not afraid.

Sister Liubai has been embroidering wedding dresses lately and doesn't go out.

This time, I didn't go to the west of Hongshan again, and just told to go to the printing office to have a look, I turned to the campus of Jinling University east of Hongshan.

After interacting with the sack girl a few times, Zhu Yuan turned to the side of the sedan curtain, and Nizi reached out to open the curtain, carefully hiding herself, only letting the adult's eyes wander.

Zhu Yuan just wanted to breathe, and on the side of the road under the guard's protection, there happened to be a few students standing next to him, and when they saw Zhu Yuan showing his head, several people suddenly bowed their hands together, and seemed to say: "I've seen Mr. ......

Well......

This is not as energetic as a "saint".

Still, it feels good.

It's not polite, but it's very reasonable.

Obviously, many students of Jinling University have been involved in just a few days, and thus realized Zhu Yuan's transformation from "Pingzhang" to "Mr."

didn't think about deliberately lifting the curtain to make people shout about themselves, so he asked Lin Xiaoyu to put down the curtain and hold the sack girl again, intending to interact.

Where is the bite this time?

Before he could decide, Zhao Xu's voice came from outside the sedan chair: "My lord, where is the printing office...... Something happened again."

Lin Xiaoyu lifted the curtain on the other side where the sound came.

Zhu Yuan was even more puzzled...... Why do you say "again"?

Looking out of the sedan car, Zhao Xu explained briefly, only to know that there was another fight.

Last time, it was Tan Qu and ...... Whoever is that, the ending is not bad.

This......

After the news came out that the "production chapter" of "The Science of Economics" allowed booksellers to engrave, it happened that the two booksellers at Jinling University first went to the editorial office of the "Daming Monthly" to find out the news, and at that time they had a dispute over the printing rights of "The Science of Economics", and then went to the printing office, also hoping to purchase a batch of this month's "Daming Monthly".

It was already the middle of the month, and there was not much left of the monthly magazine, but it had been selling very well, and coupled with the previous dispute, the two booksellers fought.

After listening to Zhao Xu, Zhu Yuan was speechless.

You guys did it on purpose, right?

Thinking wildly, I came to the courtyard of the printing office located in the southeast of the campus, and this time it was even more powerful, a large tank in the courtyard for water storage and fire prevention had been broken, and the running water all over the ground had been cleaned up, and it could still be seen that it was in a mess.

Then there were two people who were tied up like zongzi.

Zhu Yuan didn't continue to have a good temper this time, and directly ordered to drag the two of them down, each play a *** board, and compensate for the loss by the way.

Besides, Zhu Yuan was a little suspicious.

This printing office......

Is it bad feng shui, once or twice, why are there always people fighting here?

As a result of consideration, I simply made a sign to hang at the gate of the printing office: Sven is important, no fighting!
