"Official, this is the kind of Xia Kingdom sword." Zhu Qing presented the sword.

Zhu Huan took out the open sword and tried the sharpness, and asked strangely: "How can a small village cast such a sharp sword?"

"Insider, it seems that they used the 100-fold method and baked it with charcoal for a long time. I can't ask about the specific process."

The most famous forging tools in ancient times were Baijing Steel and Baili Steel.

Baili Steel is to put iron on charcoal or charcoal and burn red, then forge it, then quench it, and then burn it forge it, repeating it for a hundred times. Baili Steel is more complicated, not only does it need to be forged red, but also add a cross-stacking process.

The actual process is very complicated, but the principle is very simple, that is, carbonized steel.

It is said that Tang Dynasty Modao used the 100-stack steel technology because there is a process of stacking, and the carbonization will be more even. If it is really done forging a hundred times, it will be a terrible stacking surface, two to the power of one hundred.

But Wang Ju doesn't think that the Tang Dynasty's Modao really does it have hundreds of stacks. Not to mention the terrible labor, just talk about the cost. Although iron reacts with carbon at high temperatures, there is also an oxidation reaction during the high temperature process, so it will be reduced once forging iron. If one hundred stacks are done, one hundred pounds of iron may not be left. Iron in ancient times was very expensive. On the Song Dynasty's market, an ordinary pound of pig iron was equivalent to about 30 cents. With the financial resources of the Tang Dynasty, can it be eaten?

Therefore, the emergence of steel frying and steel pouring in the Ming Dynasty was actually a simple process of carbonized steel.

Wang Ju did not use these two methods, the cost was too high and the process was complicated, so it could not be supported by Wangjiazhai.

He chose the steelmaking technology in the early stages of European industrialization, first disassembled the knife into pieces, placed it with the carbohydrate and heated it completely, reducing oxidation and improving the carbonization process.

The extremely rough craftsmanship is better than simplicity.

After heating for several days, take out the iron and repeatedly beat it. The effect of steelmaking is to scatter carbon and to remove impurities. Because it is often forged, it can refine grains and uniform composition.

But I won’t really go to Baili, I have been stacked more than a dozen times. There are blacksmiths and Yuan Heizi in the village, but Yuan Heizi’s craftsmanship is still difficult.

Anyway, it's a test object, including its simple carbon steel, which also needs to be improved.

So the product in front of me appeared.

The effect was pretty good, Zhu Huan continued to stare at the sword and asked, "Where did he hear this craft?"

"I asked," he said that he accidentally heard a Xixia merchant reveal in the security army city. He might have thought he was young, but he didn't expect him to remember it. But he didn't pay attention at that time. One was small, the other was poor experience. When he handled the battle in Hei'aoling, he remembered it and tried it."

"The swords are all here?"

"No, I only brought ten swords, and I should be able to shoot ten more."

"In other words, just about forty swords can be turned into twenty swords?"

"good."

"Why is there so little loss?" Zhu Huan couldn't help but pace, and suddenly laughed again: "He's really a suspicious boy."

Only part of the sword is used to make sword hilts, scabbards, and decorative sword bags or sword boxes. This involves leather craftsmanship, inlay craftsmanship, wood craftsmanship, paint craftsmanship, and smelting craftsmanship, which are far from what Wangjiazhai can do. Moreover, if a sword is made, there must be sales channels. Even if it is a real Xia Guo sword, can it be sold at a high price in the hands of the people of Wangjiazhai?

However, Wangjiazhai is not completely at a disadvantage, and in the final analysis, he must have a sword in his hand.

In fact, Zhu Huan performed well, and all the money from those horses was given to Wangjiazhai for pensions.

But that's different. It's one-time. It's long-term. It's business. Wang Ju can't figure out how bad Zhu Huan is. The Zhu family must make a little profit, but the proportion of profit is the key.

So he only handed over ten of them. If the Zhu family was too unintentional, Wang Ju would look for other families, which might be troublesome, but he would be prepared for any trouble.

Zhu Qing laughed.

"Forget it, find someone to process these ten swords. Let's see how much it costs and make half the profit each."

"The official is wise."

Compared with other wealthy families in Yanzhou, the Zhu family only rose to prominence when they were both Zhu Huan and his son. The trick is that they are not ugly. Of course, if they provoke the Zhu family, the Zhu family will be equally decisive. This is the real way to survive on the border.

Zhu Qing turned his head and looked at Zhu Huan's second son Zhu Jun: "What's wrong with Erlangjun?"

Zhu Jun was punished to kneel wherever he was punished.

"I was so angry that I was killed by this little beast. He met a beggar on the road yesterday and actually gave him a few taels of gold ingots together."

A trace of worry flashed in Zhu Qing's eyes. Zhu Huan had four children in total. The latter two were born by a concubine and were still young. Zhu Huan's wife gave birth to two sons. The eldest son Zhu Qi loved male style and had no children after several years of marriage. Some people even said that Zhu Qi's wife is still a virgin. The second son Zhu Jun is another nerd.

"We can't live for three generations, can't the Zhu family survive for three generations?" Zhu Qing thought to himself.

He had a sudden inspiration.

"Manager Zhu, what do you want to say?"

"It's better to let Erlangjun go to Wangjia Village."

"Not appropriate," Zhu Huan said, where is the owner handed over to the mule?

"With the sword, will that village still make a mule in the future? Erlangjun is not a stupid person, but has less training. The young man is strange and clever and decisive in his work. This is exactly what Erlangjun lacks."

Zhu Huan was a little moved by this statement.

…………

Yuan Heizi raised the hammer and forged the sword on the forging stone. His voice was as wonderful as a powerful symphony, but Yuan Heizi was sweating profusely.

"Put it into the furnace." Wang Ju said.

Yuan Heizi was put back in the furnace. When it burned red, Wang Ju said again: "Take it out, no, add a little hot charcoal residue."

This time, Yuan Heizi didn't have to do it himself, his apprentices did it for him.

"Why do you need this?"

"I don't know, but this method is used to forge the other side of the mountain," Wang Ju simply replied. This is the normalized quenching process. A complex process, even if you want a good sword, you have to test oil quenching and salt water quenching... Even this simple forging requires quenching technology, but unfortunately no one pays attention to this era.

Wang Ju's quenching process is still extremely rough, but no one can understand how Wang Ju answers it.

"I am not a material expert, so I can only debug slowly," Wang Juxin thought.

After a while, Wang Ju said, "It's almost done."

Yuan Heizi's apprentice, Wang Quan's second son Wang Qiang, immediately took out the sword and threw it into the furnace, then burned it red, and then put it into the stream water to quench it.

Looking at Jianyuan Kuroko, he said, "Big Bull, how much money will it be worth?"

"How many jin of money?" Wang Juya burst out laughing. Xixia has three weapons that can be used, including cold forged armor, Xixia bow, and Xia Guojian. A good jin of Xia Jian is worth a thousand gold, one thousand taels of gold, and two thousand gold. Of course, this value of jin of gold is an imaginary amount, but the best jin of Xia Jian is often worth a thousand coins, and even a slightly worse one is worth hundreds of coins.

Wang Ju doesn't expect to sell for hundreds of guan, but he won't only have a few guan.

A villager came over and said, "The boss's manager is here."

"Just say Cao Cao, Cao Cao will arrive, let's see how much his family will give you."

After coming to Wang Quan's family and making a little noise, Zhu Qing pointed to the sword box and said, "It is the real Xia Kingdom sword."

z "Can you let me see it?"

"The official asked me to bring it to you for your reading and reference, but it's okay to read it."

Zhu Qing said, pulling out the Xia Guo sword from the scabbard.

"Brother, look at its craftsmanship and its sharpness and toughness..."

The scabbard has gorgeous patterns full of northwest style, and the sword edge is green and cold, just like a proud prince.

"Good sword," Wang Ju stroked the sword and exclaimed.

The Zhu family brought Xia Guojian, which not only allowed Wang Ju to watch and learn from, but also had a layer of intention, which showed that the Zhu family was not terrified, and the sword you cast was still very different from others, and it could only be worth so much money.

After reading it, Zhu Qing said the matter: "The official plan to give your village a sword twenty swords."

"Twenty Kills?" Yuan Heizi couldn't help but look at his hand. He could actually shoot out a weapon of twenty Kills?

Others were also happy. One sword was twenty silos, and twenty swords would cost four hundred silos. That was the income that the whole village would not get in a year for a mule!

Wang Ju's face was very calm, mainly because the craftsmanship and quality were not kept up. If he could cast a real high-quality Xia Guojian, he would not be able to give him a 200-six ​​sprite one.

It also does not include the cost of other materials such as iron and carbon. If it weren't for those who were holding knives and giving twenty cents of money, the village might have only been able to actually get ten cents of money. However, for the poor village, it is also a considerable amount. And as the technology improves, the profit will gradually increase. Therefore, Wang Ju didn't say anything.

"The official said that the profits are divided in half. Brother, what do you think?"

Wang Ju nodded at this time. The Zhu family was very sincere, after all, there were also many jobs over there.

"But if so, I hope Dongweng will provide you with high-quality iron, carbon, and other materials. I will write a list for you later."

Carboniferous was started to be exploited and used on a large scale in the Song Dynasty. There were also two carboniferous pits in Yanzhou, but the quality was not very good. As for iron, the materials that were strictly under supervision and formal production, Wangjiazhai had no channels to obtain a large amount of pig iron or cooked iron, let alone good iron.

"OK."

"In addition, I would like to ask Dongweng to provide two highly skilled blacksmiths to come and support."

Zhu Qing looked at Wang Ju suspiciously.

Wang Ju was helpless. Yuan Heizi was also good at craftsmanship, but he couldn't keep up if he wanted to cast the top-notch Xia Guojian. Not to mention his understanding of the complex quenching process, even the stacked Yuan Heizi could not achieve perfection. Moreover, in order to increase the speed, Yuan Heizi brought several apprentices. This is a good thing, but he had to teach him step by step. Yuan Heizi couldn't be busy alone.

As for whether the blacksmith of the Zhu family would learn it, maybe the core technology is in the sealing kiln.

Zhu Qing couldn't figure out the intention, but nodded and agreed.

"Stay this sword first, let us learn from it for a few months, and can we return it to Dongwen later?"

"no problem."

"Then let's make an appointment." The two of them swear by high-high.

"Brother, come with me." Zhu Qing took Wang Ju outside, and there was a pretty young man standing outside, at the age of sixteen or seventeen: "He is the Erlangjun of the official's office."

"I've met Zhu Erlang."

"I've seen Xiaolang."

"The official's meaning is to let Erlangjun stay in your house for a while."

"He's staying at my house?" Wang Ju pointed at Zhu Jun's gorgeous clothes and couldn't help laughing.

PS: Cold forging armor, generally forging is hot forging, but this cold forging process is forging after the iron is cooled, so the nail plates are stronger and of course more labor-intensive. Moreover, because it is difficult to forge after cold, it can only be used for thin nail plates, but thick swords cannot.

The arch and crossbow shooting further and more accurately may not necessarily have to be strong. There are also materials and scientific designs. For example, the pulling force of the bow and arrow in the Olympic Games in later generations only requires 30 to 50 pounds. In the Song Dynasty, it was not considered a qualified crossbow soldier. However, the range and accuracy of the bow of the Song Dynasty may not be as good as the "light bow" of later generations. The Western Xia crossbow has a design problem. In addition, the yak horns from Ganzhou were used. Where did the yak horns in Ganzhou were obtained in the Song Dynasty? It was a strategic material for the Western Xia, and even if it was obtained, it was very rare. Therefore, a good bow of Xixia would often be worth hundreds of dollars.

And Xia Guojian may have used the Baidai forging technology, but there may be some alloying technology.

These three techniques are complex, the yield rate is low, and the cost is high. Even if the Western Xia is not armed, the Song Dynasty tried to copy the village many times, but it was not successful. Therefore, this sentence is left behind, "Khitan saddle, Xia Guojian, and Goryeo secret color are all the best in the world. Even if it is used elsewhere, it will never be able to achieve it."
