"Big Stone Forest."

"Big Stone Forest."

Yu Liyan and Xiao Chang greeted each other when they saw someone coming.

Big Stone Linya, this is a celebrity. Qin Mu didn't expect that it was this person who freed himself.

Yelu Dashi, just look at the surname and know that he is a member of the royal family. He was the only Khitan jinshi in the Liao State with historical records, and he became a Hanlin. The Hanlin of the Liao State is called "Lin Ya", so they all respect him as Da Shi Lin Ya.

The high-level leaders of the Liao State were proud to learn from the Great Song Dynasty, and they all spoke Chinese, so Qin Mu could understand the words of Yu Liyan and others. If they all speak vernacular, then Qin Mu will be blind, and he will completely listen to the book of heaven.

Yelu Dashi is a royal family, so he is naturally worried about the situation in front of him, he came to the armory today to see the equipment situation, but he didn't expect to listen to such a good show outside the door.

Between Yu Liyan and Xiao Chang, Yelu Dashi is naturally inclined to Yu Liyan. This is a family member, a surname.

But he had to admit that what Xiao Chang said was very reasonable. If it weren't for Qin Mu's words, he would have been ready to help his relatives.

Yelu Dashi was a little hesitant now, although he stopped Yu Liyan's impulse to prevent the situation from getting out of control, but what to do next? Is it to let Yu Liyan stop messing around and put national affairs first, or do you believe that Yu Liyan will build a brand new weapon once?

Da Shi Linya is a top talent in the Liao Kingdom, and he understands that it is difficult to stop the Jin Kingdom with only the current Liao army. What's the use of making more armor? When fighting with the Jin State, the Liao State Leather Room Army was not without armor, and it was not defeated.

No matter how much you build, you may lose more slowly, and even this may not be possible.

The emperor didn't do anything, hunting all day long, he didn't care about anything, and all the state affairs were handed over to the Xiao family. However, the Xiao family is a good hand in the court battle, and they are completely incapable of leading troops to fight.

Xiao Fengxian's own brother, Xiao Sixian, led his troops to fight the Jin Kingdom, not to mention the defeat of the battle by throwing away his armor, and putting all the responsibility on his generals. His subordinates were punished, and some were even executed, but because he had a good brother and two good sisters, he had nothing to do.

Such a Xiao family, how dare Da Shi Linya rely on it.

Yu Liyan said that this person could make new weapons, which made Yelu Dashi have other ideas in his heart.

If that steam crossbow is really so powerful, it can't defeat the Jin country.

In any case, you should try it.

However, the dispute between Yu Liyan and Xiao Chang must also be resolved. What Xiao Chang said makes sense, and Yu Liyan's request is not too much, so the only entanglement lies in steel.

Da Shi Linya thought for a moment, and said to Qin Mu: "Qin Mu, this steam crossbow you built is so powerful, it seems that you are a rare good craftsman." ”

He had listened to Yu Liyan's introduction outside, and knew Qin Mu and the steam crossbow: "Good craftsman, I want to come and make steel." In this way, I can give you enough iron, and you can make steel yourself. How is it? ”

Yelu Dashi deserves to be called "Lin Ya", his proposal not only solved the problem, but also maintained the face of Yu Liyan and Xiao Chang, and no one should be offended.

Qin Mu thought for a while, nodded and said, "Okay, I agree." ”

As long as Yu Liyan is not allowed to get mad in front of him, Qin Mu will agree. He has no other way now, he can't run, don't make himself uncomfortable.

Moreover, ironmaking and steelmaking is Qin Mu's next plan, just practicing in Liaoguo, adding some experience points to his future.

Even if the Liao State is messed up, he is not afraid, anyway, it is someone else's career that is bad. The Liao Kingdom will be gone soon, and they won't care about losing some iron or anything when they come.

Qin Mu wanted to make steel on a large scale, which was a plan that had been set a long time ago, so he has been learning the knowledge of steelmaking and ironmaking in the 21st century.

He knew that steelmaking was not easy in this space-time because there was no low-cost way to remove carbon from iron in a short time.

The difference between iron and steel is the carbon content. Steel is actually a ferroalloy, and iron with a carbon content of 0.02% and 2.04% is steel.

Coal was used in ironmaking in this time and space, and there were many elements in coal that were extremely harmful to ironmaking, so coke was used for ironmaking in later generations. It is to pre-process the coal to remove some substances that are harmful to ironmaking, and the iron that comes out in this way is no longer the iron of this time and space.

The iron produced by the steel mills in later generations is already similar to the steel of this time and space, at least it will not be broken if it is made into an iron rod.

Qin Mu couldn't get steel, so he could only make steel by himself. This time and space is known as "100 times made into steel", which shows that it takes a lot of time and effort to make iron into steel. What he lacked most was time, and he couldn't hold a pile of iron to knock and beat. He didn't have the time, and he didn't have so many people to use.

Although Xiao Chang sold Da Shi Linya's face and agreed to Qin Mu's casual use of iron, he would never allocate more personnel.

What can you do with such a small number of people? Twenty-four hours a day and night iron striking is not enough to see.

Speaking of time, Qin Mu was also angry. His watch is still on Yu Liyan's wrist, and he won't return it to himself. This made him unable to even determine the time, depending on the sky estimate. It's almost back to the era of Ru Mao's blood drinking.

And the food of Liao is also poor. In the Great Song Dynasty, especially in Bianliang, the diet is very good. There were already stir-fried vegetables in this time and space, so Qin Muzhen didn't feel wronged by eating. But when it comes to Daliao, it can't be done.

The development of the diet presupposes an extreme prosperity of the economy. Compared with the Great Song Dynasty, it is as if China in the seventies and eighties was too far behind the American imperialists.

It's good to have something to eat, you are a captive, what qualifications do you have to pick your mouth.

Qin Mu felt that even for the sake of his stomach, he had to run early.

He didn't come to the Great Song Dynasty to do penance, and he didn't want to be a monk.

In order to run early, you have to hurry up and get a steam crossbow. After Qin Mu inspected the ordnance station, he chose a place to prepare for a coke kiln. This knowledge is all on paper, pure theory. The pattern is there, but Qin Mu has never done such a job, he can only move his mouth, not his hands.

According to his own ideas, he drew the structure of the coking kiln.

The craftsmen who worked for Yu Liyan were all smart people, and they had already seen Qin Mu's unique drawings when they were building the steam engine, and now they have not many problems when they see the coking kiln.

Just do it. In two days, a small coking kiln was erected.

Then it's coking. After all, Qin Mu had put some effort into the big steel smelting, and the coking was successful once. After obtaining coke, Qin Mu borrowed a small iron-making furnace and began to make iron with coke.

For this, Xiao Changzhi did not interfere. First, Yu Liyan said that this new method of iron-making can directly produce steel, which is greatly beneficial to the ordnance institute, and second, the iron-making furnace used by Yu Liyan is also the smallest one, and there are several such furnaces and ordnance, and it is unreasonable not to give Yu Liyan a single one.

On the day of the new method of ironmaking, even Dashi Linya came to watch.

The craftsmen have long been skilled in making this set, and they cut the material in turn, but this time the coal, here called charcoal, was replaced with coke.

Then the refining begins.

When the molten iron came out, it really didn't disappoint Qin Mu.

He was not a man in this business, but even from a layman's point of view, this furnace of iron far surpassed the iron of the past, almost as much as steel. Qin Mu didn't know how much it was different. It's a lot better anyway.

Yu Liyan and Da Shi Linya were surprised, and at the same time, extremely excited.

How can you simmer the charcoal for a while and then smelt the iron to get steel? They certainly don't understand the principle. Yu Liyan asked if he didn't understand, this is related to the future of Liao.

With such a clever iron-making technology in Liao, whether it is armor or sword, it will be upgraded by more than one grade, which can be said to have saved half of Liao's life. Not to mention that legendary steam crossbow.

Yu Liyan is not a fool, for a while, she vaguely understood that Qin Mu would not be able to make an iron horse for her - Qin Mu shirked that there were not enough tools, but there was no iron horse, with this new method of steelmaking, plus a steam crossbow, it was enough to spare his life.

But the death penalty has been spared, and the living crime cannot be escaped, and it is unforgivable to dare to deceive himself.

Yu Liyan originally planned to get a thousand iron horses and let Qin Mu go, but now it seems that the iron horses are hopeless, so don't think about this person leaving.

If you don't use it for Liao, who will you use it?

Who doesn't know that the Liao State is the most powerful existence today? Is it to Da Song? The Great Song Dynasty couldn't even defeat the current Liao State, let alone the Liao State after the new method of iron smelting and steam crossbows.

Yu Liyan believes that those who know the current affairs are Junjie, and Qin Mu must know the current affairs. Follow yourself to have a bright future. She forgot for a moment at this time that the Liao Kingdom had lost half of its rivers and mountains, and life and death were only between the lines.

While she made up her mind, she asked, "Young Master Qin, why do you use coke to make iron, and you can produce steel?" ”

If Yu Liyan is in a good mood, he will be called Young Master Qin Mu, and if he is in a bad mood, he will not be given this treatment.

This has an advantage, allowing Qin Mu to simply judge Yu Liyan's mood.

Yu Liyan's words are exactly what Da Shi Linya wants to ask. He also waited intently for Qin Mu's answer.

"The difference between iron and steel is the amount of carbon." Qin Mu patiently popularized science to the two: "Coal, that is, what you call charcoal, there are some things in it that are harmful to ironmaking, and only by making coal into coke can the harmful substances be removed, so that the carbon content of the molten iron can be reduced." If the carbon content is low, it will naturally be steel. ”

"Carbon content." Yu Liyan nodded. Actually, she didn't understand it at all.

Da Shi Linya was also confused.

Qin Mu said that the carbon content, this "carbon" is a carbon element, how can they have the concept of elements, since they say "charcoal", they think it is charcoal, charcoal. But according to Qin Mu, if you want to reduce the content of charcoal, wouldn't it be good to put less charcoal?

But if you put it less, you can't burn it.

Although Qin Mu's words are not long, in later generations, people who basically hear them can understand everything, but don't forget that people in later generations have all gone through nine years of compulsory education, and these things have been learned in junior high school chemistry. Even after a long time, the knowledge is returned to the teacher, and it is not a problem to understand.

Yu Liyan and Da Shi Linya have not received nine years of compulsory education, a simple sentence is enough for them to think about it for a lifetime, how can they understand and understand it so quickly.

The molten iron condensed into a steel ingot, which was placed in front of him, and the facts showed that Qin Mu was not a liar, not nonsense. What he said must have made sense, but we didn't understand it for a while.

Not to mention Yu Liyan now, even Dashi Linya decided to entertain this clever craftsman. He must not be treated as a prisoner.

Xiao Chang was also beside him, and he was shocked when he saw Qin Mu directly turning iron into steel like a ghost. This is also too capable, no wonder Yu Liyan believes in him. Yu Liyan is a woman with eyes above the top, or she would not have married until she was seventeen years old, but she tied up a man from the Great Song Dynasty.

Sure enough, he has the ability. But if you miss the ability, you can cheapen yourself.

How to do the coking kiln, he can see it all. Immediately ordered to go down, as it were, to build five coking kilns in a row, and immediately start a new method of ironmaking.

Qin Mu didn't care about their plagiarism at all. He was very happy. What was written on paper finally came to fruition. This time, the coking and ironmaking went so smoothly that it was like playing billiards and clearing the table with one shot, and it felt very refreshing.

Xiao Chang wanted to scale up, which made Qin Mu even happier. This has a practical example, and in the future, it will not take a detour to build its own Weishanhu steel base.

But Qin Mu didn't think about whether he could go to Weishan Lake at all. Not to mention Weishan Lake, it's hard to say that even Zhongjing can't go out.

With his performance, if Yu Liyan is still willing to let him go, it will be really lacking in heart.

Obviously, Yu Liyan not only does not lack her eyes, on the contrary, she still has a lot of eyes.

That night, Yu Liyan sent a maid to warm Qin Mu's bed.

It's a bonus, and it's surveillance. She watched it with her own eyes during the day, but she couldn't see it at night, so she sent a maid to watch it, and she couldn't let Qin Mu escape from her eyes anyway.

This made Qin Mu suddenly fall into huge trouble.

The woman sent to the door, Qin Mu definitely can't ask for it, he can't be sorry for his group of little ladies.

This night, Qin Mu endured very hard. He decided that he had to protest with Yu Liyan tomorrow. I tired myself half to death during the day, and I still have to torture myself at night? Still don't let people live?
