When Lin Chu got up, he saw Han Junye lying in front of Wei Rou's bed and fell asleep.

She whispered to Song Tuo: "Take the child back to the room."

In Lin Chu's opinion, no matter how sensible Han Junye is, he is just a child, sensitive and insecure.

After leaving the room, the night wind blew, and he could still feel a chill on his body. Lin Chu subconsciously hugged his arm tightly and covered his head with a wide cloak. She looked up and saw Yan Mingge's chin with cold and hard lines.

"Have you finished eating?" Lin Chu let Yan Mingge tie the straps for him to wear the cloak.

This cloak is made of Yan Mingge. It was much bigger when worn on Lin Chu, almost wrapping her whole body, leaving only a small head exposed outside. The lantern hanging in the corridor emitted an orange light, making Lin Chu's face look a little softer. Her white porcelain-like skin was extremely delicate, and her smiling eyes were full of gentleness and made people's hearts look.

Yan Mingge reached out and pinched her face: "I'm losing weight. I haven't had a good meal these days when I'm not here, right? I just asked the kitchen to cook soup and send it to the room. You go back and drink some soup to warm your stomach."

"I'm not hungry, I have important things to do." Lin Chu said, looking inadvertently, and found that the cloak strap Yan Mingge tied for him was very... ugly.

She had no choice but to take it apart and tie it again.

"What important thing can't be done tomorrow?" Yan Mingge raised his eyebrows. Although his voice had not changed much, Lin Chu could still feel his displeasure.

"When steelmaking is concerned, the blacksmith sent someone to send a message saying that he had boiled the iron water and could not have someone guarded the ironmaking furnace all night. I will go there tomorrow?" Lin Chu was anxious to go to the blacksmith, but was afraid that Yan Mingge would be unhappy, so he pinched the back of his hand.

Yan Mingge obviously liked these small moves very much. He pinched Lin Chu's hand with his backhand and pulled her to the yard over there: "I'll go with you."

"Don't you still have to accompany the guests?" Lin Chu was a little confused.

"Guest?" Yan Mingge raised his voice: "You said Mu Xingfeng? Yu Gong, he is now the counselor of the third prince. We are in different camps, so we have to avoid suspicion. Yu privately, his subordinates treat my wife badly, but I am not so generous. Therefore, it is already a perfect end to their meal."

Lin Chu was amused by his nonsense words, but she still knew that Yan Mingge was alienated from Mu Xingfeng, and there must be other reasons. She said: "Will you offend him like this?"

Yan Mingge laughed: "A person like him is too smart. Nothing can escape his plan. If he offended him, he would have offended him eight hundred years ago. He is the master of his own, and he knows this better than me."

The two of them said, and had already arrived at the blacksmith's shop.

As soon as he entered the door, he felt the heat rushing to the face. The fire in the stove was burning very strongly, making the whole room look red. The blacksmith was pulling the bellows. He was only wearing a short brown dress with a short and bare shirt, and he was still sweating profusely.

"General, Madam." Seeing Yan Mingge and Lin Chu coming, the blacksmith hugged and clapped their fists.

"No gift." Yan Mingge said. His eyes swept around the shop and finally landed on the boiling iron. "Use this to craft iron to produce hundreds of steel?"

During the years he was in the mountains, he still saw Wei Rou hit a lot of iron, and he was not proficient in this profession, but he probably knew what the procedures were. He usually just burned the iron ore to soften it. This was the first time he saw him directly burning the iron water.

"This... I did it according to my wife's instructions." said the blacksmith.

Yan Mingge looked at Lin Chu in confusion. Lin Chu looked around the house and said, "Let me find a bluestone mortar to pound rice, and find a few more wooden sticks."

The soldiers guarding outside the door immediately went to look for them, and soon they moved these two things.

Lin Chu looked at the iron in the iron smelting furnace, then looked at the bluestone mortar, and suddenly slapped his forehead: "Why did I forget this!"

Yan Mingge was very upset when he saw her face, and his eyebrows frowned: "What's wrong?"

"There was an accident in the morning, and I didn't have time to tell the blacksmith that he had to connect a water outlet on the stove, otherwise the iron would be boiling so much, so how could he get it into the bluestone mortar?" Lin Chu regretted that his intestines were blue. She thought that the furnace might not be able to burn the iron, so she didn't rush to talk about it.

The melting point of iron is more than one thousand degrees. What tools can she use to scoop the iron water?

"Just bringing the iron into this bluestone mortar?" Yan Mingge asked.

Lin Chu nodded in dismay.

Yan Mingge pinched her hand a little harder and whispered: "Leave it to me."

"What are you doing? My husband, this iron is much hotter than boiling water, don't..." Lin Chu wanted to say something, but after touching Yan Mingge's eyes, he shut up bitterly.

Yan Mingge then said, "You retreat."

Lin Chu and the blacksmith both retreated for more than two meters away. Yan Mingge's hands spread slightly and drooped, and airflow seemed to gush out of his palms. Slowly, a cyclone rose all over his body. The black robe danced without wind, and the broken hair on his forehead was a little messy. The flames in the stove were swaying from side to side by side by side by hurricane, and the light also became extinguished with Ming.

Lin Chu was so embarrassed that he couldn't open his eyes by the hurricane that he raised his sleeves to block his face. His vision accidentally touched Yan Mingge's figure. She suddenly felt like this man was like a god of creation.

Yan Mingge's wide sleeves were blown up like sails by the true energy. He used his internal force to lift the iron in the furnace and led it to the bluestone next to him.

The molten iron and the bluestone wall connect, making a "hurrying" sound.

The capacity of bluestone scoop is limited, and a small amount of molten iron remains in the stove and cannot be made out.

The airflow around Yan Mingge slowly disappeared, and the hurricane in the room also stopped.

The blacksmith's soul is shocked: "The general is young and his internal strength is so deep."

Lin Chu stuffed a wooden stick into his hand: "Don't be shocked, stir up the molten iron!"

She strode forward and handed Yan Mingge a wooden stick, then first inserted the wooden stick into the iron and stirred it vigorously with her arms: "If nothing unexpected happens, the iron in this scoop can be matured."

By stirring, the contact area with air is increased. The oxygen in the air will oxidize the carbon in the iron. When the carbon in the iron is reduced to a certain extent, a paste metal will be formed. Repeated stirring will become a mixture of cooked iron and waste residue.

Yan Mingge directly took the wooden stick from Lin Chu's hand and stirred the iron for her: "What is cooked iron?"

"It is also a kind of iron, but it is relatively soft and cannot be used to build weapons." Yan Mingge did not let her do these rough tasks, and Lin Chu was happy to stand aside to guide her.

"You can't build weapons, so why bother to practice them?" The blacksmith had waste a lot of effort in order to burn this pot of iron. When he heard that he could not build weapons, he became a little angry. Isn't this a waste of iron ore?

After saying this, the blacksmith felt that the air pressure around him was a little low. He accidentally glanced at the opposite side and found that Yan Mingge looked at him with a deep look.

The blacksmith was shocked by the eyes and stirring the molten iron was half a beat slower, so he had to shut up obediently.

Lin Chu then said: "Although cooked iron cannot make weapons, with it, it is thousands of times easier for us to make steel than forging with one hammer!"

When the iron water from the bluestone scoop solidified, Lin Chu asked the blacksmith to take a small piece of cooked iron and beat it into thin slices, then directly clamped the iron sheet with tongs and rolled it around the remaining pig iron liquid in the stove.

Let the cooked iron sheets be soaked directly in the pig iron liquid. In this way, the pig iron contacted by the cooked iron will not only produce a good carburizing effect, but also produce a severe oxidation effect, which separates the iron and slag, and produces steel with little slag and uniform composition.

The blacksmith used fire tongs to pick up the iron piece, beat it twice, and then picked it up, and found that the iron piece had become extremely bright. The blacksmith was so shaking that his hands could hardly hold the fire tongs, so that the fire tongs and the iron piece fell on the iron platform together.

He was so excited that he could hardly speak: "This... is this a hundred steel making? Can you make a hundred steel making without a thousand tempering?"

Yan Mingge used two fingers to pick up the iron piece, and the internal force burst out with his fingertips. He heard a "collapse" sound, and the iron piece was in two pieces.

The smiles on Lin Chu and the blacksmith's faces were stiff.

Lin Chu picked up the iron piece that Yan Mingge had broken with his fingers, and his expression could not hide his frustration. Although when I watched martial arts dramas before, I thought the male protagonist's fingers were very handsome, but what I broke is her hard work, it is not so beautiful.

Is steelmaking failure?

Lin Chu was about to try this iron piece by himself, but Yan Mingge took it over.

"Be careful of being hurt." Yan Mingge scolded.

Lin Chuxu grabbed her hair with annoyed. She couldn't figure out that the problem was there. Is it because the step of turning the iron into cooked iron that was not carried out in the square pond made of the earth pit?

"I'm sorry, my husband, I thought... I could make steel in this way..." Lin Chu was a little incoherent, because she was too blind and confident, thinking that she could make salt last time and this time she could make steel.

Looking at Yan Mingge's shiny iron piece neatly broken into two pieces, she felt frustrated.

Yan Mingge frowned slightly, and rubbed Lin Chu's big palm on his head: "What apologize? Who said you are not practicing steel? The hardness of this iron piece is comparable to that of a seventy-two-forged sword."

Lin Chu was a little confused when he heard this.

Seeing that she obviously didn't believe in her, Yan Mingge directly clamped the steel sheet with tongs and placed it on the iron platform, and spoke to the guard beside her: "Give me the knife."

The guard quickly took off the sword from his waist and handed it over.

Yan Mingge used fire tongs to fix the steel sheet with one hand and held the knife in the other hand and cut it down hard.

With a "ding" sound, the guard's knife was broken into two pieces.

Everyone was stunned, and the room was silent for a short second.

Lin Chu cried out, breaking the silence.

Yan Mingge was so shocked that he threw down the tongs and knife handle in his hand and walked over, and took Lin Chu's hand to look up and down: "What's wrong? Did he be injured by the bursting fragments?"

Lin Chuyi punched him in the face: "I'm almost scared to death by you."

She thought she failed to make steelmaking one second, and then told her that she had made steelmaking success. This was exactly the same as when she was in college, she heard that she had failed to make a mistake. When she checked her grades, she suddenly realized that she had not failed the exam but wanted to cry loudly.

Yan Mingge was caught off guard by this punch, and there were so many people present. Yan Mingge wanted to scold her, but she was crying and she burst into tears. She could not say anything about the fierce man. She just whizzed and turned on the air conditioner while coaxing people: "I just want to try the hardness of this fine iron."

The blacksmith and the soldiers at the door dared to watch, they hid far away quickly.

Lin Chu knew he was embarrassed, sobbed twice before stopping the crying. He buried his face in Yan Mingge's chest and rubbed his tears through Yan Mingge's clothes.

Yan Mingge was so amused and laughed: "No way you are like you, you are like a little dirty cat."

Lin Chu glared at him angrily, "I haven't washed your clothes yet!"

There are many things in the house, and there is only Jing He, a maid. Sometimes Jing He is so busy that he can't get rid of himself. Lin Chu is not spoiled, so she washes her clothes with Yan Mingge.

Yan Mingge touched his nose and stopped talking, but he was already thinking that he had to buy some maids to enter the mansion and not to suffer his stick.

Lin Chu held the steel sheet and his smile was almost cracking to his ears. He said to Yan Mingge: "My husband, let's get the iron ore back quickly. At this steel-making speed, it is no problem to build a fine iron weapon within the prescribed time limit!"

Yan Mingge nodded: "The road to the Broken Soul Stone Forest is very far. I asked the spy to inquire about whether there is an iron mine near Yaocheng. Tang Jiu brought back news that there is an iron mine, but if there is no such thing as a thousand, the blacksmiths will not go to pick the ore on the mountain."

This made Lin Chu wonder, "Why?"

"It is said that the stones on the mountain are very evil. When several blacksmiths used the stones on the mountain to punch the iron, the stove suddenly exploded and the blacksmith was also killed. Rumors said that the stones on the mountain had some curse." Yan Mingge said in a deep voice.

Lin Chuyouyou said: "My husband, don't you want to know what the weapon I used to blow up the reservoir for Song Tuo and the others?"

The author has something to say: In order to be able to hard-core steelmaking, the author Jun Shangqian.com has translated all the papers on ancient steelmaking technology...

To be honest, I didn’t work so hard to find information when I wrote my professional course graduation thesis [laughing and crying]

But among the information I found, the specific steps about steelmaking are still very fragmented, and many details I want to know cannot be found at all.

The heroine in the literary text wanted to use the steel filling method, but most of the information I found only talked about melting pig iron on cooked iron to make steel. However, under the limited conditions in ancient times, the specific details of how to make cooked iron were not explained in the literature I found.

The essential difference between pig iron and ripe iron lies in the different carbon content. Pig iron has a high carbon content. The carbon content of steel is between pig iron and ripe iron, and ripe iron has the lowest carbon content. The found literature says that ripe iron is obtained by forging and decarbonizing pig iron. I am very fascinated. It is difficult to make pig iron into steel by forging. Isn’t forging more difficult and cumbersome? Therefore, the author used the technique of ripe iron in the stir-frying method to refine iron, and then used the steel filling method to make steel.
