Wu Yanzhi walked around for a while, and was generally satisfied, but he felt that this ore was a little large, and it seemed that the charge was relatively small, and it could be increased slightly.

The crushing of this ore is also relatively easy, because there is a sand river next to it, and the ore can be crushed hydraulically.

In fact, the locals do the same.

Seeing the blasting of the mine, Wu Yanzhi led dozens of officials, large and small, to the steelmaking workshop a few miles away.

It is said that the first furnace of molten steel is produced today, but in fact, it is just a show for many officials.

Because this converter has been tested several times before, and some minor modifications have been made under Wu Yanzhi's arrangement.

Blowing into the furnace is ordinary air, no high-pressure pure oxygen is blown, and there is no pure oxygen to blow.

Wu Yanzhi used to connect a number of iron pipes in the middle and use the bellows to press air (oxygen) into the converter.

They have renovated the original iron-making earthen furnace to greatly increase the amount of iron produced by the furnace to meet the requirements of converter output.

"King Donglai, Yao Shilang, and Liu Tingshi, please sit ......," Judge Jiang Shipeng arranged.

After everyone was seated, the judge said to Wang Jin, "Eunuch, you can start." ”

"Okay." Wang Jin nodded.

Then he began to direct, pouring molten iron from the blast furnace into the converter.

In a moment, the red molten iron has reached the predetermined position in the converter.

Then someone added quicklime to it. Then seven or eight men added pieces of pig iron to the big iron basket that pleaded the lever of the converter.

Needless to say, the role of this lever is not elaborated, as soon as the pig iron block is added, under the magnification of the lever several times, the converter of more than 20,000 catties will be quickly straightened!

The bellows kept blowing air inside, and Wang Jin watched the reaction of the furnace fire according to the method of Wu Yan's teaching.

After about twenty minutes, I saw Wang Jian wave his hand and stop: "Stop!" ”

The bellows stopped the blowing.

"Yao Gong, Liu Tingshi, Liu Dianzhong, and all my colleagues, the thousands of catties of molten iron in this have turned into steel!" Wu Yanzhi stood up and introduced it personally.

"Huh? So fast, in the past, these thousands of catties of steel were hundreds of blacksmiths, and I am afraid that it will not be finished in a month! ”

"Yes! I wonder what King Donglai added to it? So amazing? ”

"Quite possibly! Is the king of Donglai mortal? Look at the zinc he invented, doesn't it make the annual pinch increase by millions of catties? Who else can do it except King Donglai? ”

“……”

The crowd was amazed!

"You may still have questions about whether the molten iron has turned into steel, but after an hour, the molten iron will be cold, you can try it and see if it is true. There is no basis for words, seeing is believing! Jiang Shipeng saw that some people didn't believe it, so he introduced them.

……

"Sure enough, it's steel! And this steel is not bad, you can directly make steel knives! Eunuch Wang introduced to the officials.

The difference between steel and iron is still clear to most people.

Seven or eight people who didn't quite believe it walked up and tried it carefully, and they all praised it.

The Xia official waiter wanted to look at it, and he was amazed: "With so much steel, my Great Zhou soldiers can hold a good knife, but it will be indestructible!" ”

"It's nature! However, Yao Gong, although this knife is good, it is not as good as firearms after all, and this steel is still mainly used to produce firearms! Wu Yanzhi said.

"Well, King Donglai's words are reasonable. In the future, with so much iron and steel, the price of this iron will definitely come down, and it will be more convenient for the people to use iron! Yao Chong said.

He saw this grand scene today, and his heart was extremely excited.

This king of Donglai is really not simple, he is simply a god!

In just two years, zinc, firearms, and copper production increased several times, and the Turkic and Khitan rebellions were defeated one after another.

Now, this strange steelmaking method has been invented, and in an instant, steelmaking is 10,000 times easier!

These things are like dreams! Where can the average person do it?

Is this the work of mortals? It is really a saint who was born!

……

Sand River, afternoon.

Wu Yanzhi discussed with Yao Chong and Liu Min

Political affairs.

Na Yao said: "Lord Wang, the contemptible people will rush to Taiyuan, Hedong tomorrow to supervise the matter of weapons and armor, I don't know what other instructions the prince has?" ”

"Don't dare! Yao Gong is in charge of Xia Guan, where do you dare to instruct? However, this armor and weapons workshop is indeed under the supervision of Shang Fang.

Contemptible meaning, this scale should not be too large, as long as it satisfies the defense of the armies in the northeast of the river! In the future, we will mainly rely on gunpowder and firearms. Therefore, armor can be produced a little more, and the number of bows and arrows must be controlled. Wu Yanzhi said.

"The prince's words are reasonable, and the contemptible people will reduce the number of military personnel under the control of Xia Guan as appropriate!"

Wu Yanzhi explained some things to Liu Min again. That Liu Min is a good person, where dare to offend Wu Yanzhi, he just blindly agreed.

Now that the Wu and Li families are vying to be the crown prince, the king of Donglai has sprung up, and his power cannot be underestimated. Especially when he actually became the final sacrifice on top of the great gift of sacrificing Jiuding, not only makes people have some associations, maybe he will soon become a prince.

In the evening, the Sand River Inn.

Liu Min was about to rest in peace when Yufei came.

"It's General Jade, please come in!" Liu Min was very polite, this was the person next to Wu Yanzhi.

I went to see that Yufei didn't come alone, but I saw that with a wave of his hand, four people came in carrying two boxes of things.

"Liu Dianzhong, this is a little bit of King Donglai, they are all native products of Xingzhou, and they are newly bought by our prince himself!" Yufei introduced.

He also dealt with Wu Yanzhi, and the last time he investigated the destruction of the Jiuding workshop, he came on behalf of Zuo Sutai.

Wu Yanzhi had already inquired about his details clearly.

"How does this work? Why is King Donglai so polite? Liu Min didn't refuse, and Yufei knew he wouldn't refuse.

"Our prince has always been very fair. Liu Dianzhong is very capable and young, so the prince will naturally recommend Liu Dianzhong to several prime ministers and saints, and he will soon be dressed in scarlet clothes when he comes to Liu Dianzhong! ”

"Thank you, General Yu! King Donglai has made remarkable achievements in handling copper and iron affairs, and his management of this gunpowder workshop is more rigorous than that of the Shangfang Fire Weapons Supervision Department, and he will report to his body one by one. ”

Liu Min is very happy, this Yufei and Yao Kuan, two years ago were nothing, but now they have won three battles with King Donglai, and have risen to the fifth rank, which is many times faster than his own move of the Ming Jingke more than ten years ago.

In recent years, there have been people in the DPRK and China who are good officials.

"By the way, Liu Dianzhong, King Donglai heard that Liu Dianzhong has a brother-in-law, who seems to be a law student and has already obtained a background.

Our prince is in need of a person who understands the law, if Liu Dianzhong is interested, he might as well let him come to Judge Jiang. Yu Fei further seduced.

"This ...... It is best to have some people around the prince who are in the Jinshi department or the Ming Jing department, he is a law student, how dare he accompany the prince around......" Liu Min was very surprised.

"Otherwise, he came to be a magistrate, just to supervise those unlaw-abiding metallurgical supervision officials and inspectors, but it's really good! Liu Dianzhong knows that our prince is in charge of the winter official monk and the eunuch, and he has all the opportunities, where can he manage this specific affairs......"

Become a pusher as soon as you go? Liu Min couldn't believe it: "This ...... Since the king of Donglai sincerely invited, after returning to Luoyang, he asked him to hurry to Xingzhou to meet the prince. "Please Baidu "Throw Book Network" Thank you for your support!
