I do research in ancient times

Ning Zaozi lived in a cement house not far from the new dining room. It was a single-story single-family house with a front and back yard designed to separate his personal living room and study room from the public meeting room.The carpenter class built tables and chairs according to his requirements. Everyone is sitting at the table wearing shoes now, mainly to prevent the old socks in the blacksmith workshop from poisoning during the meeting.

Now the main building is vacant, and the only residents are the wooden statues of wicked saints.When moving, Mr. Xie wanted to bring him to the new house together, but Ning Fei sternly rejected him, saying that he should keep the Mozong tradition and not force the sage to move.

Heh, he got rid of the bad luck with great difficulty, so don't ask for trouble.

"Burning pig iron essence, using heavy and soft collars, and several nights will make steel. This is the method summed up by a senior named Qi Wuhuaiwen. Specifically, put wrought iron in the furnace, and put the pig iron plate on the furnace mouth , keep heating with fire, when the temperature reaches [-] degrees, the pig iron starts to melt, at this time, clamp the pig iron with tongs and move it left and right, at the same time, someone keeps turning the wrought iron, so that it is evenly poured into the pig iron liquid, changing the carbon content of the alloy , making it into the category of steel.”

"To do this, first we need to mass produce iron."

Ning Saw drew a new smelting furnace on the wooden board, and then made a fork on the previous furnace.

"There's not much difference, the main difference is the location of the blower."

"I have seen the current structure of the furnace in the blacksmith workshop. The height of the blast has actually been improved, but it is still not high enough."

"If we raise the tuyeres further, the path of hot air is upward, so the molten pig iron droplets produced by smelting will avoid the directly blown air, and a liquid pool of pig iron can be formed. At the same time, because the iron is relatively heavy, the slag ore Impurities such as powder can float on the molten iron. We open a small opening between the tuyere and the bottom of the furnace, and the slag can be released, and it can be observed through this discharge opening whether the pig iron liquid in the furnace is full. "

"Once the furnace is full, the molten pig iron can be discharged, poured directly on the wrought iron plate for casting, and the steel can be tapped."

After Ning Fei finished speaking, the sound of breathing came and went in the concrete room.

It turned out that everyone was so focused on listening that they didn't even dare to take a breath, for fear of missing some important key point.

Ning Zazi smiled lightly.

"Don't worry, steelmaking is not that simple. As I said before, pig iron is only one of them. There is a second key point, furnace temperature."

Ning Saw started knocking on the board again.

"There are three key points in the furnace temperature, first is the blast, then the fuel, and finally the design of the furnace body."

"Mass production of steel is impossible by manpower, it requires animal power or water conservancy, but there is no rush, we can make the steel first and then discuss mass production. I draw the furnace design here. The blast furnace can delay the heat loss in the furnace and save energy. Fuel. Blacksmiths now use coal for ironmaking. The temperature of the coal is sufficient, but it contains too much sulfur and other impurities, which easily pollute the molten iron, so we need to make coke.”

"How to make coke? Cut off the air and dry burn."

In this class, Ning Fei talked until late at night, and everyone heard it late at night, and they were so intoxicated that they were very reluctant to go to the bathroom.

Although they still don't understand many things, Juzi undoubtedly opened a door to a new world for them.There are many things that I couldn’t figure out before, but I seem to have an epiphany after this explanation, and the picture of the blast furnace drawn on the wooden board makes everyone in the blacksmith’s mood excited, wishing to rush out immediately to burn bricks. Kiln, try it yourself.

That night, everyone in the blacksmith workshop suffered from insomnia.

Many of them have heard of the glory of the blacksmith workshop since they came to Mozong. In the past, all the famous knives in the world were made by Mozong. It's just that after leaving Yunfu Mountain, this prestige has disappeared.

Some people say that the craftsmen of Mozong cheated the world and stole their fame, and they could go straight to Qingyun through Yunfu Mountain, and if they left, they would fall into the mud.Everyone in the blacksmith workshop refused to accept it, and they wanted to restore their prestige.But the Xue family's Longquan Jianfang suddenly emerged, and Mo Zong's skills were indeed inferior to others. Gradually, the blacksmith workshop fell into silence.

After listening to Juzi's lecture tonight, Mu Donglai originally thought that he would tremble with excitement, because he finally had the opportunity to fulfill his master's long-cherished wish and regain the prestige of Mozong's blacksmith workshop.

But in fact, he was much calmer than he expected, and he didn't care too much about fame and prestige.

He was thinking more about the unintelligible truths that Juzi said.Such as composition, such as structure, such as elements.

In the dark, these things are connected in series, which seems to be able to explain the principle between heaven and earth, it can explain the formulas that the master only asked him to memorize before, and it can explain why their hundred steelmaking is not as good as Longquan Jianfang.

So in the future, as long as they operate step by step according to Jizi, they can make better steel than Longquan Jianfang!

Early the next morning, Ning Fei woke up half asleep and went to the bathroom to relieve himself.When passing by the living room, he suddenly felt that something was wrong, and when he raised his head suddenly, he saw a group of people's heads crowded in darkness outside the window, almost bursting into urine in fright.

Ning Zaozi: ... Fuck, I'm a little terrified!

Ning Fei opened the door, and sure enough, all the people squatting on the side of the road were people from the blacksmith workshop.

They were also obedient, and they all squatted outside the yard and waited quietly, one by one neatly next to each other, and they didn't know how long they waited.

Ning Fei: "Aren't you all sleeping?"

Mu Donglai stood up, with a little panic on his face:

"Did you disturb Moko's rest? I'll go back later."

As he spoke, he kicked Xu Jin next to him.

"Walk around, tell me not to let you crowd here, why are you disobedient!?"

Xu Jin was also very wronged.

"I didn't understand what I heard last night. I couldn't fall asleep after thinking about it all night. I don't want to ask when Jizi wakes up in the morning."

"Besides, Master, aren't you here too?"

Ning Fei looked at the sky, in fact, it was almost dawn, and according to the time on Niubei Mountain, it was actually not too early, and the people in Wubao had all come out to work.

He wiped his face, signaled everyone to come in first, and went to the small kitchen to wash and change his clothes.

Clay had delivered breakfast when he came out.

The Mozi set meal is a cup of goat milk, a plate of wild vegetables, and a whole grain steamed bun.

Recently, the goods of "Ning's Workshop" have been sold so fast that Ning Zazi has made a huge profit, but he has enough money to add some staple food to the sect.

He raised his head and asked everyone in the small conference room, "Have you all had breakfast?"

Listening to his question, kid Clay reacted the fastest.

He stared at everyone in the blacksmith workshop, and said vigilantly: "If you want to eat, go to the dining room. Aunt Niu made this for Juzi!"

How dare the people stay, and scattered like birds and beasts one after another.After the meal was finished with the chopsticks, everyone in the blacksmith workshop sat back neatly, more obedient than the sheep in Wubao.

Ning Fei thinks this is not okay.Students miss too many classes and have almost no foundation. It is impossible for others to talk about theory.

"so."

He touched his chin.

"Let's build a coke furnace and an iron furnace according to the drawings. You actually operate it by hand, and you will understand after a few tries."

Hearing what he said, everyone burst into cheers.

The blacksmith workshop was originally handed down from hand to mouth. In the past, the master master also taught his apprentices in this way. Those who are savvy can understand a lot after reading it.

So on this day, the blacksmith workshop that had been silent for a long time became lively again.The hands-on ability of Mo Zong's disciples can be said to be strong. Ning Fei only gave a few instructions, and everyone used ready-made materials to build a simple iron-making furnace, and then used an abandoned fire kiln to transform it into a coking kiln, and successfully trial-produced it. The first batch of coke.

"Juzi, do you want to feed?"

, Mu Donglai stood by the blast furnace inlet, his hands trembling slightly.

This is not the first time he has started a furnace to smelt iron. He has lived by the furnace for half his life, and he has never been so nervous as he is today.

"Let it go."

Ning Fei nodded.

"Pay attention to the height of the molten iron in the furnace. When it is almost full, start to put it in. Don't wait until it is completely submerged."

"Good!"

Xu Jin near the material outlet responded, and then gestured to Liu Tie, and the tall man immediately started blowing.

The rest of the people gathered around, watching the three of them smelting iron without blinking.The heat quickly rose, every face was covered with beads of sweat, and the clothes were quickly drenched with sweat.

But no one cares.Wipe your face when you sweat a lot, and go outside to grab a bite of snow to eat when you are hot. Everyone takes turns to go to the dining room to get the food. Everyone takes turns to blow the blower, non-stop, and there seems to be flames burning in their eyes.

Finally, Xu Jin approached the discharge port again, and exclaimed in surprise.

"Okay! It's time to pour molten iron!"

Then, he carefully flipped the switch on the hearth, and the next moment, the red molten iron rushed down, pouring like a spring on the wrought iron placed under the bottom of the furnace.

"Turn! Turn the clinker!"

Ning Fei reminded.

"okay!"

Mu Donglai immediately grabbed the handle, swung his arms round and began to turn the wrought iron, and beat it with a hammer while turning, making sure that the molten iron soaked more evenly.

He felt that he probably used all his life's strength, every blow seemed to hit his heart, at the same frequency as his beating chest.

steel!

their steel!

Their Mo Zong's pouring steel method!

Since Mu Donglai was born, the steel that he has made with his own hands must be successful!

At the end of the knock, Mu Donglai was already in tears, his wrists trembling slightly.

Xu Jin snatched his hammer and smashed it again and again, his eyes were also red.

Afterwards, the blacksmithing became a ritual.When one person is tired, he will switch to another one. The hammer circulates in everyone's hands. I don't know how many times it hits the iron material, and each stroke is sonorous and powerful.

Ning Fei backed out silently.

In fact, the iron is almost knocked out, and knocking again is just a waste of time and manpower.

He respects this kind of tragedy, and they are worthy of admiration and respect for a group of craftsmen who are obsessed with improving technology.

"Brother Jizi, won't you let them stop?"

The kid Clay who came out with him looked disgusted.

A man does not flick his tears lightly, how can he work while crying?Not in a carpentry class like his.

Ning Fei was looking up at the sky, when he heard this, he lowered his head and smiled at him.

"Stop? Why stop?"

He suddenly breathed a sigh of relief.

"Being able to do what you like all the time is the happiest thing. This kind of security and satisfaction can only be understood by those who have experienced it."

Clay didn't quite understand the meaning of his words, but he remembered Brother Jizi's smile.

Years later, when Clay recalled it, he suddenly realized that that kind of emotion was called envy, as well as the nostalgia for the irreversible past.
