"It's done, it's done!"

Gong Ming shouted while dancing.

The fiery red iron water continued to flow, like a spring water pouring out of the land.

The blacksmiths also put down their work and rushed over to watch.

The first time they saw flowing molten iron, they excitedly held each other's hands tightly.

The eyes looked at Liu Jun as if they were looking at a god.

After the iron was cooled, a blacksmith knocked the solidified iron with a hammer.

The area where molten iron is broken, revealing a white fault.

"White words." said the blacksmith.

Gong Ming and Liu Jun also came over. As the craftsman said, it was indeed white iron, which was cast iron, which was called cast iron by the ancients.

Contemporary saying is that iron with carbon content is higher than 2%.

And this is the correct product of the blast furnace.

"What you want is iron." Liu Jun said, pointing to the place where the iron flows, "It is easy to wrought iron. Dig a pool here, and the edge of the pool is also made of refractory bricks.

Let the iron flow in, stir with willow sticks while flowing, and it will eventually turn into wrought iron."

Gong Ming and others were speechless, and they naturally didn't know that this was not written on the drawings.

The method Liu Jun mentioned came from the Ming Dynasty's "The Creation of Things in Heaven".

The purpose of stirring with willow sticks is to allow the carbon in the pig iron to be fully mixed with the oxygen in the air to burn, so that the carbon content will be reduced and it will become cooked iron with a carbon content of less than 0.2%.

"It's late, Your Highness should go back and rest. I'll try again tomorrow." Hu Wei couldn't bear to let Liu Jun stay up late.

Liu Jun nodded. Although the matter was only half completed, the basic problem was solved, so the following things were much simpler.

Under Hu Wei's escort, he returned to the bedroom.

At the door, Tangyuan fell asleep at the door because she waited for Liu Jun too late.

Seeing Liu Jun come back, Tangyuan hurriedly went to boil hot water for Liu Jun to take a shower.

Liu Jun stopped her and asked her to go back to rest, and went back to her room to sleep.

The next day, Liu Jun went to the yard early,

At this time, Gong Ming and the craftsmen were chatting and laughing together with dark eyes.

On the ground, a pool for storing iron has been built, with many cooled iron blocks inside.

"Your Highness, this method is really useful. Pig iron has become mature."

Seeing Liu Jun coming, Gong Ming came over with an iron block.

"I've been busy all night?"

Liu Jun patted Gong Ming on the shoulder. The craftsman in his thirties moved him with his hard-working spirit.

"The official thought about making it for His Highness soon." Gong Ming wiped his face with his black sleeves, which made his face even more black.

Liu Jun took the iron block and looked at the broken mouth, not as rough as pig iron.

"Thank you for your hard work, let's take a day off today. I will ask the kitchen to prepare good meat and wine for you." Liu Jun said with a smile.

The following things are much simpler if you can produce large quantities of pig iron and cooked iron.

The second pot that was put into the drawing yesterday was actually the crucible in the crucible steelmaking method.

This steelmaking method appeared in the 1740s. It was this steelmaking method that ended the era of solid steel and produced liquid steel for the first time in human history.

The key to the crucible steelmaking method lies in the material of the crucible.

Like refractory bricks, this crucible requires ceramic clay to be made.

Because the crucible needs to withstand a high temperature of 1,600 degrees.

The method of refining is to put white tin and cooked iron together, and add limestone to remove sulfur.

The steel made in this way is of high quality and became the material for lathe tool and mold steel in the 18th century.

"Thank you, Your Highness."

Gong Ming and the craftsmen were smiling.

Liu Jun nodded slightly, no longer disturbed them, and asked them to go back and rest.

He came to Qinzheng Hall and took out a drawing from the base.

The title of this drawing is "Iron Molded Cannon", which is the real purpose of smelting steel.

After Gao Hongyun's death, he was not at ease.

Because the Fuyu people failed to plan internal unrest, they would inevitably adopt more radical war measures.

According to his understanding, the Fuyu people in this world are more shameless than the contemporary bran.

All dynasties have relied on the vassal of the Central Plains to survive until now.

Now he falsely accused the Fuyu people of the Central Plains, and he was quite stanced to not give up until he broke through Jingzhou.

Based on this, Liu Jun believes that he will face a long-term war with Fuyu Kingdom next.

This war will consume extremely financial, material and manpower.

That's why he was thinking about how to make money.

If he wants to defeat the strong with the weak and win this war, in addition to having strong financial support, it is also necessary to improve the weapon level of Jingzhou.

The equipment of the mesh rope gun only allowed Jingzhou to catch up with the tide of the times, and it was not said to be surpassed.

And artillery is different.

As far as he knows, most artillery artillery in Dongzhou is cast in bronze, which is very expensive and can only be equipped with a small amount of equipment.

The reason for this is that the technology of smelting steel is not up to standard.

But for him, it's different.

Jingzhou has mastered the "Iron Mold Casting Cannon" technology and is able to make cast iron cannons.

Because of crucible steelmaking technology, steel cannons with higher performance cannons can even be made.

In this way, Jingzhou can suppress Fuyu Kingdom in terms of firepower.

Thinking of this, he felt a little relieved.

If you want to survive in Jingzhou, you can only rely on technology.

After watching this for an hour, Liu Jun became calculating.

We are preparing to wait for the craftsmanship to build a small steel workshop before implementing it.

At this moment, a sudden sound of horse hooves came to mind outside the palace.

Then Li Ran hurried to Qinzheng Hall.

"What's wrong? Officials disagree?"

Li Ran's face was not good-looking, and Liu Jun thought that the salary was not going well.

Shaking his head, Li Ran said, "What happened to Haoshan Mansion?"

Liu Jun's heart suddenly sank.

After Ping'er told him about the bandits in Haoshan, he kept it in mind.

So after the new governor of Haoshan Huang Fang took office, he asked him to investigate.

"According to Your Highness's order, Huang Fang sent the Haoshan Prefecture Army soldiers and the captain of the bandits to take office. He never thought that the Haoshan Prefecture Army soldiers were ambushed by the bandits, and most of them were injured. The bandits took advantage of the situation and took over many displaced people and were attacking Qingshui County, Haoshan Prefecture." Li Ran said hurriedly.

Liu Jun frowned, although he took in some refugees from the four foreign governments.

But there are still more than 200,000 refugees still wandering around the four palaces.

Because the four outer palaces were occupied by Fuyu people, they naturally resented the incompetence of Prince Jing's mansion.

The reason why he talked to Li Ran about the land yesterday was to coordinate the arrangements and stabilize these refugees.

But now it seems that it has been used by people with ulterior motives.

"Call Xue Changqing." Liu Jun said to Hu Wei who served him.

Although the people are innocent, they are entangled by bandits and become a force that threatens Jingzhou.

He didn't want a Li Zicheng to appear on his fining ground.

Hu Wei was scared very much. Fifteen years ago, the power of the Han King swept across the three states is still being passed down by word of mouth.

Soon, Xue Changqing came hurriedly, and from Hu Wei's mouth he had learned about the chaos in the people.
Chapter completed!
