"With fire?" Blacksmith Zhang asked puzzled.

He is a blacksmith, how can an ironsmith not understand fire? But when he heard this, he was even more puzzled.

Nie Shuyao nodded and said, "That's right, this is called thermal expansion and cold contraction." ”

As soon as she heard the heat expansion and cold contraction, Nie Tianxi, who had been brainwashed by her strange theory since she was a child, understood, and said with a smile: "Sister, I understand, it turns out that heat expansion and cold contraction can still be used like this." ”

"Of course, there may be other uses that we haven't found yet." Nie Shuyao smiled happily, and once again felt that his younger brother was smart.

Black Bull, Xiaofu and the two masters don't understand this new term, and this is not just a noun but a phenomenon that most objects have.

Hei Niu was embarrassed to ask Nie Shuyao, so he asked the two masters, "Master Zhang, Tan Lao, what is thermal expansion and cold contraction?" ”

Blacksmith Zhang and Carpenter Tan looked at each other, and finally glared at Hei Niu, if they knew, would they still have this expression?

Carpenter Tan arched his hand at Nie Shuyao and said, "Miss Dongjia, we are old, we really don't understand those new words, what is the meaning of 'hot expansion and cold contraction'?" ”

"Hey, hey." The sisters and brothers looked at each other and smiled, it was really good to stump the master.

Nie Shuyao said: "This is troublesome to explain, why don't you go to the stove where Uncle Zhang is striking iron, how about it?" ”

"Okay, let's go!"

Blacksmith Zhang's blacksmith workshop is next door to them, and if he hadn't built this four-wheeled carriage, he would have been busy.

Coming to the iron-striking stove, Nie Shuyao found a piece of iron plate that had been chiseled and was ready to be rebuilt and a screw that was one point bigger.

She took the two things and said, "Shall we make a bet?" ”

Blacksmith Zhang was curious and asked, "What bet?" ”

"Bet if I can put this screw through this iron plate?"

"How is this possible, the screw is one size bigger than the hole in the iron plate." Blacksmith Zhang shook his head again and again, most of these screws came from his hands, and he knew it very well.

Nie Shuyao said firmly: "If I can do it, can Uncle Zhang give me the apprentice you brought in the future." ”

As soon as these words came out, Carpenter Tan hid his face and smiled, and their carpenters sometimes used objects beaten by blacksmiths. It would be nice to have two blacksmith apprentices waiting on call!

Blacksmith Zhang laughed and said, "I knew you would fight this idea." But what if you lose? ”

"If I lose, then this first four-wheeled carriage will be given to Uncle Zhang, and I won't take a penny. Bet not? ”

Stimulated by her words, Blacksmith Zhang slapped his hand, "Bet!" Don't regret it, girl. ”

He really took a fancy to this four-wheeled carriage, and he had a daughter who was about to get married, and there would be a carriage like this in the dowry.

"No regrets!" The siblings said in unison.

In the end, Nie Tianxi high-fived and swore to Blacksmith Zhang, and the bet was settled.

Nie Shuyao said that he would do it, and burned this piece of iron in a charcoal fire, and it didn't take long for this piece of iron to turn red. The siblings glanced at each other and were ready.

She clamped out the piece of iron with big iron tongs and said with a smile: "Xi'er! ”

"It's coming!"

Nie Tianxi also clamped the screws with pliers first, and the two masters looked at each other without blinking.

But this screw was so easy to penetrate, and at this time, the iron plate was not red, and Nie Tianxi quickly twisted the screw cap with a wrench.

When the iron plate was completely cold, Blacksmith Zhang wanted to remove the screw, but it took a lot of effort to get the screw cap off, but the screw seemed to grow together with the iron plate, and it could not be removed.

Although Blacksmith Zhang lost, he was happier than winning, this is the technique, he understands it, and others can't take it back if they want to.

"Aren't they just two apprentices, I have so many apprentices that I'm worried that there is no place to place them." Blacksmith Zhang laughed.

Then he changed his words, "However, you can't let me keep this technology a secret!" ”

Nie Shuyao smiled: "How can it." This is called thermal expansion and contraction, and it is a phenomenon that occurs in most objects, not just iron. However, we have to keep this secret for the time being, as long as our own people know. ”

This was a difficult problem, but the carriage could not be assembled together at the end, at least the carpenter's work had to be done on this iron plate, which made the carpentry more difficult.

Carpenter Tan smiled and said, "What's so difficult about this? Although the owner lady can rest assured, as long as Lao Zhang's blacksmith work is done, I can give the owner a complete four-wheeled carriage in two days, but it will take a few more days before the paint is dry. ”

"Okay, I'll wait for the carriage to appear." Nie Shuyao said.

Looking at the half-finished carriage in front of her, she smiled. At this time, in her eyes, this is not a carriage, it is clearly silver!

On the way back, several people in the carriage were still thinking about the expansion and contraction of heat.

Yuqin thought a lot, and she asked softly, "Miss, you said that most things will expand and contract." But why was the water in our tank burst after it froze that winter? ”

Nie Shuyao said with a smile: "In addition to water, water is cold and swollen and hot and contracted. Yuqin is very good at using her brains, and this month she will be rewarded with half a tael of silver. In the future, if you are willing to use your brains, everyone will have a prize! ”

"Thank you, Miss!" Sister and brother Yuqin thanked Wuniang mother and son outside in unison.

Nie Shuyao's sister and brother looked at each other and smiled, such a reward is very good. Don't always think that others are stupid, the three stinkers are still Zhuge Liang, maybe some thorny problems are found in their unintentional words.

Ten days later, when Nie Shuyao came to the workshop again, the four-wheeled carriage stood firmly in the courtyard.

This time she came with Song Yan'er, and by the way, she also brought a good horse. This horse is only seven years old, and he is in the prime of life.

The brown paint on this carriage is very light and looks more natural. The curtains, cushions and other fabric decorations made by Xiaofu's skillful hands, not to mention how beautiful they are.

Song Yan'er immediately liked it, and begged: "Sister Shuyao, can you give this carriage to my sister first?" ”

Nie Shuyao nodded without hesitation: "This car was originally intended for my sister, but ah, Sister Song has to run two laps on the boundary of our county these days, so that everyone knows about the four-wheeled carriage." ”

Song Yan'er looked at her with a smile, and pretended to be angry: "I know that you are not well-intentioned." ”

It can be said that this car is still regarded as a treasure by Song Yan'er.

With the first four-wheeled carriage, the carriage workshop is now working at full capacity to produce the next car, which is said to be used by Young Master Tianxi when he participated in the hospital examination.

The workshop now has two carpenters and two blacksmiths, and Tan Mutou, the son of Tan Carpenter, has a small apprentice in the workshop next door, which is Erlengzi. It's really hard to say the word talent, it seems that the kid has the talent to be a carpenter.

Nie Shuyao handed over the two workshops that had been started to Hei Niu to take care of, and he would report anything to the owner if he didn't need it. In the end, she made a new request for the carriage, that is, to add an iron plate in the middle of the carriage board, so that it would be safer.

In this way, the wooden planks used to make the carriage are very particular, and the furnishings in the carriage cannot be moved. This change alone was enough for two carpenters to keep their jobs busy.

After having a four-wheeled carriage, Song Yan'er sat very comfortably, and she was also willing to show Nie Shuyao this limelight, she asked people to write the word "Jiang" on the carriage. Who in Qu County didn't know the Jiang family's industry, so as soon as this carriage appeared on the street, it immediately became a sensation.

Although Qu County is not big, it is not small, and there are many businessmen who come and go, and all those who can do business in other places are bulging. They soon learned that the car belonged to Zhenweiju, so more people came to Zhenweiju to ask.

After the next carriage was ready, a "Nie Ji Four-wheeled Carriage Shop" appeared next to Blacksmith Zhang's small blacksmith shop.

After the previous publicity, this is a complete situation. As soon as the shop opened, people who were interested in the four-wheeled carriage poured in. And the one in the store is the carriage that has just been made, and the shopkeeper in the store is the black bull.

Don't look black, the black cow has good eloquence, and in the past two years, he has done odd jobs everywhere and has developed a pair of fiery eyes, which is called what a person says.

The car adopts a reservation type of sales, how many orders are placed to make as many cars, the deposit rate is 800 taels, and a car is 1,000 taels of silver. No counter-offers.

If someone makes a deposit, then the black bull will tell him again, this car is different, if you are willing to add another five hundred taels, then you will put iron sheets in the mezzanine of this carriage, and the safety will increase a lot. The deposit is still 800 taels, after signing the agreement, the car is ready, if you don't want the car, the deposit will not be refunded.

In this way, those who did not have much money in their pockets shook their heads, but there were still some rich people who ordered this car. On the first day, I received orders for four carriages, and received a deposit of three thousand two hundred taels of silver, and only one carriage asked for a wooden compartment.

Nie Shuyao, who was holding these silver tickets, smiled so much that she couldn't see her eyes, leaving 1,200 taels for the decoration of two workshops and pencil shops, and she planned to use all the rest to buy land.

In addition to buying another 20 acres of Jiang Xiaoluo's land on the edge of the workshop, almost all the Ya people in Qu County came forward and bought 300 acres of fertile land in the shortest time, all of which were dozens of acres contiguous into pieces.

Nie Shuyao, who is in Zhenweiju, has not yet visited these fields, but Jiang Yi, who is in charge of doing this for her, said that these are good fields. Although it cost her an extra hundred and ten taels of silver.

"Thank you, Gongzi Jiang." Nie Shuyao raised a glass to him, for which she personally cooked a table of dishes and promised him.

Jiang Yi smiled: "Miss Nie is too polite, Xiao Luo has made a lot of money because of your coal stove, and now he is soaking in the workshop every day." As his little uncle, it's nothing to help with this. ”

Nie Shuyao is not hypocritical, and sometimes friends don't have to worry too much about each other.

"That...... Don't call me a son in the future, it's a lot of life. I'm older than you, so call me big brother like Tianxi. He had been holding this sentence in his heart for a long time, and finally said it today.

"Yes, I also think that the eldest son is too sour, so I will ask Brother Jiang to take care of me in the future." Nie Shuyao has no objection to this.

Jiang Yi nodded solemnly and said, "Okay!" ”

The next day, Nie Shuyao took Yuqin to back up these land deeds to the yamen and asked the county magistrate to stamp them, so that their family would be a complete farmer. It's been less than a month since I left the hospital, and the time is just right.

Da Niu happily ran to report to the county master, but after Nie Shuyao waited for a quarter of an hour, he waited for the news that the county master was not there. R1152
