Cheng Chubi found that he had many identities, the emperor's son-in-law of the Tang Dynasty, the captain of the Tang Dynasty, and he was also a big landlord, a big factory owner, and a big slave owner.

Datang lacks everything, but there is no shortage of slaves. Serfs from Goryeo, orchids from the Middle East to Europe, Kunlun slaves from Southeast Asia and even Africa, and Silla women from Silla.

After Cheng Chubi told Chai Lingyu about the steel frying method, Chai Lingyu immediately bought back a group of slaves from the slave market, and then began to act according to Cheng Chubi's method.

If you can really get the steel out, it will definitely be a great achievement! Datang does not lack iron ore, but it lacks a way to smelt iron ore. When iron ore is just produced, it contains a large number of impurities, including carbon, sulfur, silicon, manganese, etc., which is not suitable for making things. The method of not dealing with the process is not the 100-for-steel method, but the frying method.

The raw material of frying steel is pig iron, and the key point of operation is to heat the pig iron to a liquid or semi-liquid state, and use blasting or sprinkling concentrate powder to oxidize silicon, manganese and carbon, and reduce the carbon content to the composition range of steel and wrought iron. One of the most important is to melt pig iron into a liquid state, which has a high melting point and is difficult to melt.

After the steel is fried, you can start refining weapons, in which the quenching process is also very important, but the most important thing is how to fry the pig iron into steel.

Chai Lingyu looked at the strange blast furnace in front of him, and asked with considerable doubts in his heart, "Can it really be made into steel?" ”

"Nonsense, when did I lie to you?" Cheng Chubi showed an extremely confident look on his face, and said: "This is called a blast furnace, the hot air blows in from here, and the charcoal is burned more vigorously, the flame is high, the temperature is high, the iron is melted into water, and then various minerals such as toner are added, and it is stirred into steel." ”

"How do you know this?" Chai Lingyu was a little curious, what kind of person was the person she married? Why does it seem like he knows everything?

You must know that Cheng Chubi was a well-known gentleman in Chang'an.

"From the ancient books, in fact, the method of frying steel appeared in the Western Han Dynasty, but unfortunately it was not able to spread." Cheng Chubi shook his head, pretended to sigh sadly, and said: "The method of frying steel has appeared in the Han Dynasty, and those so-called sword-casting masters have regarded this method as the biggest secret of their own casting weapons, and only passed on to their sons-in-law and not outsiders, as a result, war and disease struck, and some people died before they had time to pass down the secret, and this method was lost. There is very little time for the book to arrive, and the book ...... Forget it, in short, I just see it, it can be said that I am the most powerful reader in the entire Tang Dynasty, and the legendary Xuefu Wuche is talking about me. ”

"Oh? So what books have you read? Chai Lingyu asked.

"You really asked the right person this sentence, I have read "Golden Sick Plum", "Meat is not a group", "Pinhua Sword", "Jade Jiaoli", in short, I read a lot of pull." Cheng Chubi said with a smile.

"Then why use coal?"

"The temperature of the coal is high, and it saves money!" Cheng Chubi rolled his eyes and said, "Although our family is rich, it is too expensive to burn it with charcoal, and our family's money is not blown by the wind." ”

Coal, that is, coal, there was a lot of coal in this era, and it was in the open air.

"By the way, are we a privately made weapon, the saint knows about it, he won't think we are rebelling, right?" Cheng Chubi asked with some concern. Li Er's rebellious family is quite sensitive, and he will be killed if he makes weapons privately.

"Don't worry, I've already told the sage, you see that those few are from the Manufacturing Bureau, sent by His Majesty." Chai Lingyu said.

"That's good, if this steel is made, Your Majesty should reward me as a prince, right?" Cheng Chubi showed an extremely smug smile on his face.

However, at this moment, a figure hurriedly walked outside the foundry.

"Pony, Princess Gaoyang is here." Cheng Di came to Cheng Chubi's side and said in a low voice.

"Oh? What is she here for? ”

"She brought ten large boxes."

"Really?" When Cheng Chubi heard this, he couldn't help but be overjoyed, and hurriedly walked in the direction of the hall, only to see Princess Gaoyang with her back to Cheng Chubi, and there were ten boxes in the hall.

Cheng Chubi walked over and opened the box, which was golden, gold-yellow horseshoe gold, estimated at a thousand taels of gold, there should still be it.

"The money came so quickly, and you won the jackpot?" Cheng Chubi couldn't help asking, and at the same time marveled at the amount of gold and the wealth of the royal family in this era.

I have to say that there is indeed a lot of gold in ancient times, and the historical records record: Emperor Wu of the Han Dynasty rewarded the general Wei Qing with 200,000 catties of gold at a time; Wang Mang married the queen in his later years and spent 30,000 catties of gold; Tang Gaozu Li Yuan rewarded his son Li Shimin for his military exploits and used 6,000 catties of gold. And in later generations, why is there less and less gold? That's because the ancients had a habit of using gold, silver and jewelry as funeral goods after death, and more than 80 kilograms of gold and various gold ornaments and utensils were unearthed from a tomb in the dusk of the sea. Another reason is that gold was used as currency during exchanges between the East and the West, and as a result, there was a large outflow of gold, especially gold and silver in a certain period of modern times.

"Haven't you heard?" Gao Yang looked at Cheng Chubi, with a hint of smugness on his face, and said, "My father has already allowed me to go to the court to listen to the government." ”

"You're amazing." Cheng Chubi couldn't help but give a thumbs up and said, "You will definitely be able to go down in history in the future." Now that you're so favored, why don't I write another strange article about you? Let's strike while the iron is hot and strive to reach the next level. ”

"How much?"

"It hurts to talk about money, just give me three or four thousand taels of gold." The smile on Cheng Chubi's face became even brighter, since your royal family is so rich, who will you eat if you don't eat?

"Okay, if it can be like the last article, I'm willing to give another thousand gold!"

"It's too little, four thousand taels of gold!"

"Two thousand taels!"

"Three thousand five!"

"Three thousand! I can't do any more, I borrowed this gold from Emperor Ke's brother. ”

"Deal!" Cheng Chubi smiled faintly and said: "I Cheng Chubi's product must be a high-quality product, you can rest assured of this." ”

"Hmph." Princess Gaoyang snorted coldly rather dissatisfied, she really couldn't figure out what Cheng Chubi was all about, he obviously had a full stomach, but he preferred to exchange it for money, if he showed his talents, he would definitely be able to become the number one talent in the Tang Dynasty.

I am working hard every day, I hope to be able to go to the next level, you are the motivation for my efforts, thank you for your support.
