The steward smiled bitterly: "Where do I dare to bring that thing into the palace!" I just think this method of pouring pig iron is really good, and if it can be used to make weapons, it is a great achievement.

It's just that the sickle is a farming tool after all, and I don't know what the effect will be if it is replaced with a blade. That's why I couldn't wait to come to the war bureau, thinking about making some swords and arrows first. ”

Liu Fang nodded: "You are right to think so, let's order to go down and let the blacksmith try to use this method to create some weapons." But you have to watch and tell them what to do. ”

The steward agreed: "This is no problem!" ”

So the two of them got busy.

The War Bureau was originally responsible for building military equipment, and there were all kinds of materials in the warehouse, as well as ways to make iron, and there were many craftsmen.

Whatever you want to build, you can do it at any time.

So this busyness was busy for most of the night.

Liu Fang specially found the most experienced twenty blacksmiths to test, and found that the effect was really good, and immediately made up his mind, and after the next morning, he would go to report the good news to Emperor Yong'an!

Although it was busy for most of the night, everyone was extremely excited, and no one was tired.

Because it was too late, the palace gate was closed, and the steward was temporarily rested in the war bureau.

In the Qin Palace, Su Jinli couldn't experience their happiness.

She practiced in the space all night, and waited until dawn before she walked out in good spirits.

After breakfast, Su Jinli changed into men's clothes again and went to the ironworks.

In the ironworks, the blacksmiths are still busy.

All the blast furnaces have been lit and iron is being smelted.

Yesterday, Su Jinli's pig iron pouring made the blacksmiths extremely excited, and she later asked people to put the raw materials into the crucible, which seemed to be to use this method to make iron.

Many blacksmiths are looking forward to it.

So not long after Su Jinli arrived, a blacksmith couldn't wait to ask: "Mr. Su, can this furnace be ignited?" ”

Su Jinli checked the stove and found that the vault was dry, so he nodded: "Light the fire, light the middle one first, and then light the two ends after the smoke comes out." ”

This firing sequence is designed to allow the coke to burn more fully and evenly.

As soon as she came out, the blacksmiths who had been impatient immediately roared excitedly and got busy.

Su Jinli stood aside, watched the blacksmiths light the fire, and after all of them were lit, he said, "Continue to blow the wind for four hours, and then it's done." Wait until tomorrow morning to see how it turns out. ”

This is only the first batch of experiments, and Su Jinli can't be sure what the results will be.

Whether it is a crucible or this simple way, it is made under the existing technology.

Although she had controlled the composition of the crucible as much as possible, she herself had not really refined it after all, so how could she guarantee that she would succeed?

So when the blacksmiths had written it down, she said, "Be careful, don't get too close, be careful to get burned." ”

Blacksmiths are not stupid, and of course they know how to be safe.

However, when Su Jinli said this, they were still a little moved in their hearts.

In their opinion, this Su Gongzi is a staff member of His Royal Highness King Qin, a scholar, and his status is much more noble than them.

But not only did he not look down on them, but he actually reminded them to pay attention to safety, this is a good person.

Su Jinli looked at it for a while, and then went to the blast furnace.

I saw that the blacksmiths were busy, and the people in charge of recording were also diligently making records.

Su Jinli walked over and glanced at the notebook in the man's hand.

When he found out that the man was recording very carefully, and that he was recording according to her request, he ignored it.

If you want to test a set of effective solutions, you can't do it in a while.

In order to ensure the output, there is only one blast furnace used for testing in this ironmaking workshop, and the others are still smelted according to the old method, after smelting raw iron, and then stirring with willow sticks to refine mature iron.

As a result, the pace of experimentation naturally slows down.

Su Jinli didn't care, and left after watching it for a while.

……

In the palace, Emperor Yong'an ended the day in the Chengtian Hall as usual, and then returned to the Qinzheng Palace, ready to eat something to cushion his stomach, and then reviewed the chapter.

Who knew that when he finished eating and was about to review the recital, Gonggong Li suddenly reported: "Your Majesty, Liu Fang, the eunuch of the Palm Seal of the War Bureau, asked to see him, saying that he had something important to do." ”

"Liu Fang? What's important to him? Although Emperor Yong'an was surprised, he still decided to meet Liu Fang, "Xuan He came in." ”

He wants to see what Liu Fang is up to!

By the way, yesterday Su's ironworks have already started smelting iron, right? I don't know how many farm tools have been built.

Liu Fang quickly walked in with her head down.

He knelt on the ground, his posture was very respectful, but his tone was full of excitement: "Slave Liu Fang, see Your Majesty!" Your Majesty, the slave has something important to do! ”

When Emperor Yong'an saw him so excited, he realized that it must be a good thing!

So his face instantly improved by two points, and he said very kindly: "Get up and say, what's the matter?" ”

Liu Fang immediately said: "Your Majesty, Zhang Dayuan, the steward of the iron-making workshop, entered the palace yesterday evening and said that Mr. Su of the Qin Palace's mansion had proposed an unheard of steel-making technique. ”

Emperor Yong'an instantly became interested: "Oh? ”

Mr. Su from the Qin Palace?

How could he not know that there was another Mr. Su in the Qin Palace?

This surname......

Emperor Yong'an narrowed his eyes, and suddenly had a bad premonition.

Liu Fang continued: "According to Zhang Dayuan, Mr. Su proposed to use the method of pig iron pouring to create farm tools.

The method is to make a sickle directly from wrought iron, then put it in a furnace to heat it, and then quickly wipe the molten pig iron juice on the edge of the sickle.

This method of creating a sickle is not only faster, but also creates a sharp edge that is not easy to wear.

Zhang Dayuan came up with the idea that maybe he could use this method to make a blade, so he found the slave and proposed an experiment, and the slave and the maid had already ordered the blacksmith to try.

It was found that although this method could not create a treasure sword, it could make some small blades and farm tools. Like an ordinary kitchen knife, it can also be made with this method. ”

When Emperor Yong'an heard this, his face changed: "Is this true? ”

Liu Fang immediately knelt down: "The slave doesn't dare to deceive Your Majesty, but this method was first said by Mr. Su of the Qin Palace. ”

Emperor Yong'an narrowed his eyes: "Mr. Su of the Qin Palace......"

Don't guess, it must be my second daughter-in-law who refuses to let people worry!

He waved his hand: "I know about this, you go down, try more, I want to know the more exact result." ”

Liu Fang keenly noticed that Emperor Yong'an seemed to be a little displeased, and he couldn't help but be inexplicable in his heart.

But he didn't dare to ask, so he could only retreat honestly.
