[Comprehensive] The days when I pretended to be a meow in the Forbidden City

Liu Yong was full of fighting spirit, but Xia Anran's first sentence made him stunned.

The young man cupped his hands and said with a smile, "Mr. Xie Liu took the time to come, but I'm sorry I didn't greet you in person. I'm sorry."

"My name is Xia Anran. The reason for inviting Mr. Liu this time is to ask Mr. Liu to compose a song for my storybook..."

His words entered Liu Yong's ear from one side, and slowly came out from the other side. Liu Sanbian blinked and blinked again, and finally extracted his meaning from Xia Anran's words——no, no Check whether to be an official?Yes, do you want me to fill in the lyrics again?

At this moment, Liu Yong couldn't tell the emotion in his heart.

Although he claims to "write lyrics according to the order", he doesn't really want to write lyrics according to the order.

But many years of sinking has somewhat polished his temper, and after hearing Xia Anran say that his surname is [Xia] and his first name is [Anran], Liu Sanbian thought that the official was hiding his identity, and silently complained about the official in his heart. The family is not very good at taking pseudonyms.

Because it is Xia Tian now, the surname is [Xia], and the name is [An Ran] because he intends to make the country peaceful. Hmph, if someone else will definitely not be able to solve this problem, but he is Liu Sanbian!

Therefore, he was very cooperative and bowed his hands, asking Xia Anran to deliver the manuscript.

Liu Sanbian naturally read "Fighting Alliance". In his eyes, although this volume is novel, it does not have much taste value.

To put it simply, this is a book that looks pleasant, but it doesn't make people want to treasure it and study it again and again.

If Xia Anran knew his evaluation, he would definitely praise him for his accurate reading, because this is fast food literature.

It’s enough to have a good time after watching it, and naturally there is no more taste. It’s just a small storybook for playing time.

But now I know that the author of this script is today...cough.

Liu Yong is still very conflicted about whether to spit out words of praise against his will.

He originally thought that Xia Anran wanted him to compose lyrics and music for that storybook, and he was ready to force it, but the clinker Xia Anran took out another book.

The page binding method is very convenient for reading, and you don’t need to be too careful during the reading process, which improves the reading experience a lot. When Liu Sanbian saw that the protagonist is a lady, he suddenly became clever. Cough, frankly speaking, his personal reading tendency is still love novels , I also wrote a few story books in a vest, and received a lot of praise.

Even if it was written in the storybook, Liu Sanbian believed that he would not lose to others.

Unexpectedly, the love and love that I thought I would see did not exist, but the other half died as soon as it came up.

Liu Yongyue frowned more and more, and Xia Anran, who was sitting opposite him, also clenched his little paws nervously, feeling ashamed of being read while writing a composition, and he suddenly doubted whether it was right for him to take off his vest.

After all, the person in front of him is also the number one "ci" in the Northern Song Dynasty!Fortunately, he was not given much time to dwell on this, his story was not long, soon Liu Yong read the next part, and he frowned at the beginning.

In the next part, Xia Anran writes from the perspective of the lord. In order to solve the doubts left by the previous part, in Xia Anran's setting, after the death of the battle, the lord turns into a spirit body and watches the enemy's surrender ceremony , is also considered no regrets.

Just when he thought that he was going to be locked in by the impermanence of black and white, he found that he couldn't help being pulled by something.

Then he crossed half of the north with his comrades in arms, and was finally sent to the hands of his fiancée.

Yes, it is in the hand.

His soul was chained to the armor.

After that, he could only be a bystander. Although he had thousands of words, he couldn't express them because he was dead.

He looked at his fiancée in a daze, watched his fiancée arguing with his family, and finally resolutely married his tablet, and watched his old teammate wipe away his tears, pretending to be his elder and being worshiped by his wife.

He wanted to slap the brother and scold him for taking advantage of him, but he could only stand blankly beside his teammates and watch the lady bow slowly, with a faint smile on her lips, as if Satisfaction, but also regret.

The hand that wanted to land on the brother fell powerlessly and clenched into a fist by the side.

He and his wife met at the end of Weiwei, and they were already talking about marriage, and they also gave the dowry, but when they heard that the border was in danger, he still put on the military uniform and left his unmarried wife to go to the battlefield.

He knew his wife's feelings for him.

I also know how I feel about my wife.

Why go to war?

It has nothing to do with him, there are tens of thousands of soldiers in the Song Dynasty, and he is not alone, so why should he go to die?

Because the day he entered the camp, the soldier commander said something meaningful to them: You will serve in the army for a day, and you will serve in the army for life.

Back then he didn't know what he meant, and when he knew it, the soldier who said it had already fallen.

His captain was the first batch of people who re-approved armor.

He knew that he was going to serve as a chariot for the mantis, and the army hadn't arrived yet. They were just sent to the front line to delay the enemy's pace with their lives.

But he also knew that without him standing in front, tens of thousands of people in the Song Dynasty would be trampled by iron cavalry. If all the soldiers didn't think so, then they would kill their parents, wives, sons, close friends, and everything else. Everyone is exposed to the enemy.

If he doesn't leave, he can only keep his own home. If he leaves, he can keep thousands of homes.

He remembered that before he left, his wife asked him tearfully, "When will you be back?"

How did he answer it?

By the way, he said at the time, "If you don't return it once you go, you will never return it."

Mu Niang also asked him, "What about me?"

His answer was extremely cruel, "It's okay for Mu Niang to marry someone else."

Then he put on the battle armor that Mu Niang had repaired for him, and took the silver gun that Mu Niang had polished for him, and rode away.

Unexpectedly, when he came back, Mu Niang was indeed married, but it was his memorial tablet.

Mu Niang said, I look forward to your return every day, but you have not returned. Now I only hope that your soul will come back and join hands with me again.

He wanted to stop this ridiculous wedding, scolded his mother-in-law, and woke up his father-in-law and mother-in-law, but he couldn't do anything because he was dead.

The winter of this year was very cold and long, but fortunately, when spring came and warmed up, he was used to the days of being tied to the armor.

His armor was well cleaned by Mu Niang, and then put away in his own room, so he just went with the flow and stayed in their wedding room.

He would listen to Mu Niang chatting to his memorial tablet, and watch Mu Niang mend clothes for him under the lamplight, and then burn them one day.

In fact, he wanted to tell Mu Niang, don't burn it!I can't receive it, what a waste, it's better to change it and wear it yourself.

But he couldn't because he was dead.

Because he was dead, he couldn't stop Mu Niang from marrying his tablet, couldn't wipe away her tears, and couldn't protect his Mu Niang in gossip.

Fortunately, his parents-in-law decided to adopt a son for Mu Niang. The child was only two or three years old, but he was very clever, and he seemed to be able to see him with his dark eyes.

He made a face at the child, and the child giggled in Mu Niang's arms.

Later, when the child grew up a little bit, he realized that he was wrong, but this boy was naturally bold, and he didn't tell anyone. He only asked him quietly one day who he was, and when he learned that he was his name. After his father, he immediately rushed forward and wanted to beat him.

Then he pounced.

The children called him a bad person, called him a big bastard, his vocabulary was poor, so he could only swear over and over again, and he answered them all.

Because he is.

He is the most irresponsible husband-in-law in the world.

He didn't take care of his wife for a moment, but instead made her and their child a burden.

The child ignored him for a full year, and then suddenly one day he came back with a swollen nose and blue eyes, and then he came to him and said he wanted to practice martial arts.

Since then, the children practiced with him in the martial arts field every day.

He held a silver gun in his hand when he died, and naturally he also held a gun after he died. He taught this child how to shoot. His parents-in-law have excellent eyesight. This child has a good talent and a good character.But he didn't know if he could see that day.

His soul has become weaker and weaker.

He knew it was because fewer and fewer people remembered him.

During the years of becoming a ghost, he gradually understood why he was like this. He had a wife who took a soul for him, and thousands of people who took a soul for him. The soldiers with the name made their obsession keep him in this world.

Of course, also because he didn't want to die.

He wanted to come back and have a look, so he came back.

But precisely because he violated the law of the underworld and was forced to stay in this world, if he disappeared, he would completely dissipate, and there would be no way to reincarnate.

But now his stature is fading, it is because the war years have passed, the people no longer appreciate these soldiers like they did at the beginning, and even the court has gradually forgotten them.

But he doesn't blame them, forgot to be good, if you don't forget the pain, how can you usher in happiness?

It's just his wife, but she hasn't forgotten him at all.

She still burns incense in front of his memorial tablet every day, and tells him what happened today to him every night.

All report good news but not bad news.

Time passed, and Xiao Lang had grown up. During these years, he accompanied his wife to send away his old father-in-law and old mother-in-law, leaving Xiao Lang alone as his wife's relatives.

The wife's family has a big family and a big business. Although according to the Song Dynasty, even though the wife is a daughter, she can still inherit the family property. It's just that some villains insist that the wife is a married woman, so they want to embezzle her family property.

Fortunately, the wife met a good official, who punished the person who wanted to seize the family property, and the wife was tortured by repeated bereavements and relatives' rebellion.

That day, she finally shed tears in front of him.

His heart felt like a knife was twisting, and he only felt that the pain was worse than when the enemy stabbed his heart and lungs.

Later, Erlang went to take the martial arts exam and became the youngest martial arts champion. When he came back, his wife looked at him with complicated and pleased eyes.

At this time, Erlang could no longer see him, so Erlang just paid respects to where he might be, and said, "I will not disgrace my father's name."

His wife burst into tears in an instant.

Later, the border war started again, and he watched his wife slowly shorten three thousand black hair, take off the silk, and put on his battle armor bit by bit.

The potholes in the heart and lungs of the battle armor had been repaired, and his wife stepped on the family's old horse, and when Erlang answered the edict, she took only his tablet and went to the battlefield alone.

It wasn't until this moment that he realized that his wife had always known that he was there.

His wife has always known that Erlang's spear skills were taught by him, so she has been learning spear skills behind his back. He thought his wife's eyes when watching Erlang practice martial arts should be gratified, but in fact she is studying carefully.

I don't know how she managed to find out that he was restrained by armor, so she often went out to practice guns in remote places, and then she concealed him.She was doing pretty well.

He didn't know whether to laugh or cry, he just felt that his wife's mischievous appearance when she was a girl hadn't changed at all.

The wife said, let's return home hand in hand.

He smiled, so let's pay it back hand in hand.

The story is very short, Liu Yong read it all, but only ten minutes.

The story is very long and soul-stirring, and in a few words, it tells the whole life of a good man and woman.

After putting down the scroll, Liu Yong sighed with emotion. He felt as if he had been split into two pieces.

As a literati, Liu Yong sighed in his heart for this pair of lovers who were clearly affectionate and righteous, but deeply missed, while Liu Sanbian, who was born in a family of officials, had to calmly think about what the officials wrote this novel. Why, and why do you want him to write lyrics and music for it.

But no matter whether it is a literati or a poet, a scholar or a smart person can't avoid the problem of thinking too much.

For the emperor's actions, they couldn't help analyzing, analyzing, and re-analyzing. Even though he hadn't entered the officialdom, Liu Sanbian's instinct still didn't dissipate.

It would be a lie to say that he did not understand the emperor's intentions.

In this novel, the purpose of maintaining the image of soldiers is very obvious. At the same time, it also eulogizes the strong and independent women, and encourages women to learn the legacy of the Han and Tang Dynasties. But for Liu Sanbian, although he admires Mu Niang She is a woman, but deep down, she prefers the petite and weak singing girls and maikos of the Song Dynasty.

But can he say that?

Can he say that when the official looks at him expectantly?

Liu Yong was silent for more than ten seconds. When Xia Anran's face gradually turned from anticipation to dullness, he lowered his head and firmly told the little emperor, no problem, he will definitely give the best. lyrics.

Then he looked at the happy expression of the little emperor, and he also showed a look of relief, and when the little emperor cared about him this year's scientific examination, he even made a big wish, saying that he had studied hard and made progress every day.

In the end, under Xia Anran's delighted and relieved eyes, Liu Sanbian secretly thought in his heart that he must bring out the book after returning home.

...Otherwise it is the crime of deceiving the emperor!

Not knowing what happened, but feeling that everything was going well, Xia Anran happily sent away the high-spirited Liu Sanbian, and then devoted herself to the work of renovating and inventing the hydraulic press.

Of course, he didn't get out the hydraulic press just to thread a needle into the book.

The scope of application of the hydraulic press is extremely wide, not to mention other things, but in smelting, it can replace the manual beating of craftsmen, especially when manufacturing relatively large weapons, it can save the time-consuming of repeated folding and beating.

This is what he discovered when he saw a foreign cold weapon enthusiast doing experiments. Using a hydraulic press can perfectly replicate the operation mode of hundred steelmaking.

Under the force of the hydraulic press, the steelmaking knife that theoretically takes three to five months can shorten the construction period to three to five days.

At the same time, he needed a hydraulic press to make another thing for him—bricks.

To be precise, it is a high refractory brick.

Ordinary bricks are generally made of clay, and are red or blue depending on the cooling method. Because this kind of brick needs to go through a high temperature of about [-] degrees during the firing process, its heat resistance is also about this level.

In the Song Dynasty, the high development of porcelain kilns increased the temperature of the kiln. According to the determination of chemical elements in later generations, the highest temperature of the Song kiln could reach [-] degrees.

The natural melting temperature of iron is about [-] degrees. Theoretically, the Song Dynasty has been able to melt iron into molten iron and then filter iron slag, but this is not the case.

Because this is only an occasional momentary high temperature.

Some people may ask, since ancient times there was no way to reach the melting temperature of iron, how did the ancients make iron?

It's very simple, because limited by the raw materials and environment, they can't reach this temperature for a long time, but they can reach the instantaneous temperature by putting in flammable objects.

This is also the reason why swords are often sacrificed by the body in smelting myths, because human fat, bones, and internal organs can raise the temperature instantly after being put into the kiln fire, but in the later stage, the dyes in the smelting process are made of wood, charcoal, etc. It was transformed into coal, and throwing it into the animal had no further effect, so this smelting method was abandoned.

At the same time, most of the smelting methods at this time are to burn the iron to the point of redness, and then beat it into shape. The redness temperature is about [-] to [-] degrees, and ordinary blast furnaces can reach this temperature.

During the Three Kingdoms period, Xia Anran promoted the use of the pouring steel method and the well-developed steel frying method.

The principle of pouring steel method is that the pig iron is compatible, and everyone can get what they want, but all this is done as a last resort when the flame temperature cannot reach, and it takes a lot of time.

In the Song Dynasty, the high temperature resistance of Song Kiln made Xia Anran want to try again.

But before that, he still has to start with the manufacture of refractory bricks. This time the refractory bricks are not the refractory bricks that only need to withstand the temperature of the kang in the Eastern Han Dynasty, but the real ones that can withstand temperatures above [-] degrees for a long time. high temperature bricks,

...Of course, it is not that easy to make. In a world without scientific instruments, there are only experiments and adjustments to the specific gravity of materials. It is said that it is possible to explode, and when the molten iron of more than [-] degrees explodes, everyone present will not be able to live.

Ordinary bricks are made by pouring clay into a mold and compacting it, then turning over and pouring it out, and putting it into a kiln to bake, but the manufacturing mode of refractory bricks is far more complicated than him.

Raw materials are different.

Refractory Bricks - Various raw materials are used depending on its temperature requirements.

These still need to be collected, and he can’t do it by himself. He can only use the power of the country. However, we can start with another important factor-density.

The more raw materials per unit volume and the tighter the combination, the stronger the strength he can bear.

Relying on its advanced porcelain firing technology and cast iron technology in the Song Dynasty, the development of refractory bricks has far exceeded that of the Eastern Han Dynasty. Xia Anran has never touched this piece. He is not sure how much temperature the current refractory bricks can withstand. Of course, this No one can give him the correct answer to the question, because there are no thermometers today.

He can only estimate roughly.

In fact, the steel output of the Great Song Dynasty was very considerable. According to the investigation of later generations, the steel output of the Northern Song Dynasty may be the first in the world at that time, but how much of it is steel and how much is iron does not count.

No matter how much iron is produced, it is always steel that determines the value of a country's force.

The enemy of the Song Dynasty was not the Xiongnu as a nomadic people, but a large Liao Kingdom with scale, organization, smelting, and scientific and technological talents.

There is also a Xixia that can rely on the vast resources of the west. Of course, they are still party items now.

The steel production in the Northern Song Dynasty told Xia Anran that they already had enough iron ore, and with the quantity, they still needed to improve the quality.

Agricultural peoples treat nomadic peoples, and only higher technology points can defeat them.

Just like the Eastern Han and Western Han used iron tools to deal with the Huns who held bone tools; the Tang Dynasty used carbon steel armor and weapons to deal with nomads.

It is a pity that in the Song Dynasty, the northern nomads developed rapidly between fighting, running, counseling, learning, and stealing. They had their own smelting industry, a source of iron ore, and captive craftsmen. .

This made it impossible for the Northern Song regime to suppress the nomads as before.

It's just a pity that Xia Anran doesn't know much about the smelting industry.

So far, the only way he can think of is to increase the flame temperature. If the flame temperature can reach the melting point of iron, then the difference in melting point can be used to remove impurities that are not iron. At the same time, the increase in the surface area of ​​the liquid can make the iron Phosphorus, sulfur and oxygen in the air combine to form sulfur dioxide and phosphorus dioxide to reduce the impurity content in molten iron.

At the same time, this reaction can reduce the carbon content in pig iron, so that it can increase toughness while reducing hardness.

The key to steelmaking is the carbon content.

If there is less, it is wrought iron, which has more than toughness and insufficient hardness.

Too much is pig iron, with excess hardness and insufficient toughness.

Only when the carbon content of molten iron is just right, it is steel. Simply put, steel is actually an alloy, an alloy of iron and carbon.

Of course, the biggest advantage of this production method is that it can reduce the burden on blacksmiths, thereby increasing the armor rate in large quantities.

After all, the molten iron that comes out of the furnace basically does not need secondary processing, it only needs to be cast and cooled like molten copper.

Xia Anran wrote the planning book according to his past habits, and he put the planning book in the category of the next ten years.

But he forgot one important point. His house is no longer the heavily guarded Dasinong Mansion because of its many secrets, nor is it the summer house with a big killer next door. Instead, there is no house ownership, only the right of residence. The little emperor's private residence.

Under the circumstances that he had already formed a habit and forgot to tell him not to touch his desk, and that day the little emperor and the awkward Eight Sage Kings finally entered the house for a small sit down, and Xia Anran happened to be carrying the little leopard to wash his hands. Its leopard paws stained with syrup were in a state of embarrassment. Due to various coincidences, he asked someone to take the two of them to the study for a while.

Zhao Zhen has come to the study many times, and Xia Anran has always maintained a casual and upright attitude. Over time, he also got used to temporarily putting down the imperial dignity and royal demeanor here, and turned into an ordinary elder brother who came to a relative's house.

Naturally, these two most distinguished men in Song Dynasty didn't want to take a peek, they were really curious about the existence of folders.

Restricted by today's productivity, this folder is actually extremely simple in Xia Anran's view, just a piece of cardboard with two iron clips.

Of course, for the convenience of using folders, he also specially ordered a batch of such large long-lined paper from the Bai family.The biggest advantage of this kind of paper is that there are dark lines as the dividing line. Because it is dark lines, it is not obvious at first glance, but it can ensure that the words are clear and clear.

But the disadvantages are also inevitable. Compared with the Eastern Han Dynasty, the paper production process of the Northern Song Dynasty is better, lighter and thinner, and its ability to absorb ink is better than before. Naturally, such high-quality paper is easily broken when using clips.

However, Xia Anran didn't know that it was because he bought the wrong paper, and just thought it was normal.Therefore, he just foolishly changed the original upper clip type to a side clip type, the force bearing area is larger, and the pressure is naturally reduced.

Such large folders are inserted one by one on the bookshelf, which naturally looks extremely chic.But it looks weird to the uninitiated.

Especially since the nephew and uncle of the Zhao family had never seen the books with the new binding method that Xia Anran brought out, let alone the spines of the books that could be written on.

What a coincidence...Of course, in Zhao Zhen's eyes, it was like a god's help. He pulled out this booklet called "Ten Years of the Song Dynasty". Just wondering why I haven't read this book...

Then, when Xia Anran finished washing the leopard, changed into clothes and rushed over to receive the guests, she saw two men who were enjoying watching him. Seeing him coming, one of them raised his eyebrows and said with a smile, "I don't know." Brother Xia... still has such fantastic ideas."

Seeing this situation, Xia Anran was not in a hurry. There is nothing unspeakable in his books, and it doesn't matter if the little emperor sees it now. As for what if the little emperor wants to do it in a hurry... there are conservatives Is Uncle Eighth Wang here?

He didn't panic at all.

Seeing his calm appearance, Zhao Zhen showed no signs of dissatisfaction. He tapped the paper, pondered for a moment, and said, "Brother, I really want to see the day when Brother Xia stands in the court hall."

His eyes were shining brightly, and he was actually excited at this moment, "Brother Xia, what you wrote on the spine of this book is ten years...does it mean that it can be achieved in ten years?"

Under the stern gaze of the Eight Sage Kings and the scorching eyes of the little emperor, Xia Anran answered honestly after pondering for a moment, "No, the book was written for ten years, and it was done by An Ran. .”

After finishing speaking, he coughed dryly, and said with some pride and pride, "In fact, Anran has already built a hydraulic press."

"Oh?" Zhao Zhen was really overjoyed, and hurriedly asked Xia Anran to take him to see it. After he also tried to use the hydraulic machine to drill a few holes, and took the needle plate that he took off separately and tried to pierce the needle with his own strength, Xiao The emperor was pleasantly surprised, "It really saves a lot of effort!"

The two tried the hydraulic press to press peach kernels, gold nuggets, silver ingots and other activities with great success. Finally, the little emperor took out a sword and let Xia Anran try to press it. Xia Anran was speechless looking at this Holding the sword of cold light Lingling, seeing his attitude, the little emperor asked with some regret, "Can't this be suppressed?"

"This one won't work." Xia Anran said, "Your Majesty, if you want to break the sword, you must make a bigger hydraulic machine."

Zhao Zhen opened his mouth, first looked at the former coin that had turned into a puddle of gold and silver pancakes, and asked after hesitating for a while, "But, what's the use of this...?"

What's the use?

Xia Anran's eyes lit up, and he was going to talk about hydraulic presses to those Song people who don't know how to rejuvenate the country through science and education. What he said was intoxicating, and Zhao Zhen's expression changed from bewildered to dazed, and then he was also excited When he got up, only the Eight Sage Kings looked calm.

When Xia Anran mentioned that boilers were used to smelt steel and produce molten iron, since then swords would no longer be forged, he suddenly asked indifferently, "Didn't Anran lose her memory? Where did you get these...?"

The author has something to say: Liu Yong: I have seen through the official naming method!

Lu Xiaofeng: I got information from this name GET.

Xia Anran: Meow meow?Isn't my name the author to match any combination at random?

Author: You are talking nonsense!This is the deep love my mother gave you!

======

Ordinary hydraulic presses only need to ensure sealing. Of course, this kind of press can press about 1T at most. It is impossible to reach 20T every minute.

After all, the applied force must be considered. After all, the hydraulic press is not created out of nothing, but the expansion (or should I say transmission?) of force. In modern times, it is transmitted through mechanical energy, but in ancient times, a force was actually exerted.

The inspiration for thinking of this came from a foreign cold weapon brother who wanted to make a hundred steel smelting, so he used a hydraulic press to press the iron block.

Steelmaking is a process of folding iron blocks in half, and this step can be done using a hydraulic press.

That is to say, if it is operated manually, it may take 3 to 5 days, or even four or five workers, to knock on a piece of iron in turn. According to the records of the Han Dynasty, it takes about three months to manufacture a hundred steelmaking weapons. Of course, not only one weapon was manufactured in the past three months, but it can also be seen that it took a lot of time.

During the Eastern Han Dynasty, what An Ran transformed was the method of making steel, so in the Song Dynasty, what we had to transform was the method of smelting and beating.

As mentioned in the article, steelmaking is not an easy task. The temperature at which iron melts into molten iron is 1500 degrees, but in fact it is precisely this temperature that hinders the pace of ironmaking. There are also high temperature resistant bricks, although there are many The novel talks about blast furnace steelmaking. The source of inspiration for blast furnace steelmaking is probably the era of large-scale steelmaking during the Cultural Revolution. It is true that steel can be smelted through blast furnaces, but the premise is that it is very coincidental that high temperature resistant bricks can be obtained.

The high temperature level of ceramics is actually an instantaneous temperature, that is to say, for a chemical substance, as long as the temperature reaches it at this instant, its color will change, but this is not the case in ironmaking. The temperature is maintained for a long period of time, so that the elements inside have enough time and opportunity to react with other oxidants, so as to achieve the purpose of eliminating as many impurities as possible in the molten iron.

So if you want to get better steel, you must melt iron into molten iron.

Therefore, the first step is to start with bricks. All large-scale iron-making businesses that do not first produce refractory bricks are paper tigers, and they must be fried properly.

Of course, as a quick time travel article, the author will definitely omit a lot of technological points, but in the writing area, with a responsible attitude and an attitude of preventing cuties from doing so after time travel, the author still needs to follow up with Please make it clear, otherwise you will be misleading your disciples.

So before the refractory bricks were manufactured, we could only use the old method to build weapons, and the existence of hydraulic presses was crucial.

There are many kinds of paper in the Song Dynasty, not only Xuan paper, but also thick paper, and the surface is waterproof to a certain extent, so it will be written like a watercolor pen, but Xia Anran, as an ancient and modern person without common sense, he, I don’t know, So he bought plain rice paper hehehe.

Did Xia Miao fly away today?

Fly away.

This body is flawed, flawed.
