Li Eryixing made a great surprise. This method of wrought iron really gave him a big surprise.

Empress Changsun’s eyes shone, “Is this what our Sheng’er did?”

"That's!"

"Otherwise, who can learn so well in the world?"

For a moment, Queen Changsun also had a smile on her face.

This kid is so proud!

But at this time, Du Ruhui said, "Your Majesty, please look at this method of wrought iron."

"That's right, look at when will the Ministry of Works be used to build it!"

"Yes. Yes..."

Du Ruhui took the booklet.

He found that the binding method of this book was a bit special.

But thinking about it, it is actually very good that Your Highness lives in the countryside and has the conditions to learn calligraphy.

Open and look.

It turns out that there are small characters in the fly head that I saw when I glanced at it during the day.

However, it is completely different from ordinary handwriting. Although the font is small, there is no trace of ink stain at all, and it is clear as if it is carved by a knife.

Du Ruhui was amazed. His Majesty wrote good handwriting! But the handwriting did not seem to be written like an ink brush, and he really couldn't see what kind of brush he used.

Not just handwriting.

After watching this for a while, Du Ruhui found that the content was also... very difficult to understand.

Although almost every page has pictures, the strokes are accurate and various values ​​are marked.

But precisely because of the rich information, Du Ruhui was dizzy and excited.

I couldn't help but sigh in my heart, why did Your Majesty be so rigorous in his studies? Often, young people were scolded by their elders if they couldn't read books, but today they turned around.

And there are many nouns in it, such as metallographic and so on.

Du Ruhui even asked and didn't know anything.

"How about, Lao Du. Can this method of wrought iron still work?"

"Your Majesty, this book..."

"Oh? What?"

"This book is very difficult and extensive, I'm afraid I can't understand it thoroughly."

Li Er was stunned for a moment, I'll go and be true.

Although Du Ruhui is the Minister of War, the Ministry of War also needs to manage military weapons. How could he not understand it?

Frowning, Li Er couldn't help but complain that Du Ruhui was so confused at such a young age?

He grabbed the booklet directly with his hands.

After seeing this...

Not to mention Du Ruhui, his face immediately turned blue.

The contents in it,

He was really profound and profound. He never expected that the art of wrought iron would have so many magical changes.

He believes this booklet, let alone iron smelting, even if it is elixir!

Li Er was a little stunned.

This kid is too smart and can only read the books he writes. So... what else can I do with this wrought iron?

After looking through this for a while, he found that the last few pages seemed to be able to understand.

...

How many hours do you add charcoal to the stove.

When charcoal is added to the stove, how many parts of sulfur should be used... as a combustion aid to increase the temperature.

The forging hammer should be powered by waterwheel, which drives large forging hammers, and will be fully explosive forging.

The waterwheel should be built like this... (a design drawing)

During forging, it should be stopped when the iron tool shows...

Li Er smiled immediately.

"Kiming, you are still not careful enough. What I wrote before is the principle of the method of wrought iron and the Tao."

"The last few pages are the specific technique!"

Du Ruhui was stunned and took the booklet from Li Er.

After going back, there are indeed a few pages of clear and clear forging methods.

"Some people know what it is, some people know why it is..."

"Your Majesty first discusses the reason, and then gets it right... This is a learning that even a great scholar cannot compare to."

Du Ruhui looked through the method of wrought iron behind.

This time, there was also an excited smile on my face, because... I finally understood...

Empress Changsun did not understand the use of iron and did not interfere in the affairs of the government.

However, the books written by one's children can make the famous officials amazed today.

As a mother, I feel so beautiful!

Li Er also had a smile on his face.

Giving a child should be like a grandson!

But at this moment, Du Ruhui's face suddenly froze.

He suddenly saw a few sloppy handwritten characters at the end of the page number, as if marked:

"Fool forging steel method, complete √"

"Li Sheng, remember, don't always talk to people about the principles in the future, and who can understand this. Just apply the fool's plan and it's all done!"

Du Ruhui was speechless.

Your Highness is indeed a genius who is comparable to that of Guigu.

The extremely magical method of wrought iron for us is just a common method in the eyes of Your Highness, and even a stupid method...

However, this iron-wrought technique is indeed very useful, and Du Ruhui will never deny this.

"Your Majesty, I have understood the law of Your Highness."

"Okay, let's call the best blacksmiths and replace my Xuan Armor Army with the best armored weapons!"

"Yes, your Majesty!"

"etc."

Li Er suddenly remembered something again.

"There is one more thing you have to do, raise pigs!"

"Raising pigs?" Du Ruhui was stunned for a moment. He had thought about raising pigs... but...

"According to your Highness, this method of raising pigs still requires medicine, this..."

"No, I have thought about this matter carefully. The key to preventing the plague is not about medical treatment. Do a good job of cleaning and separating the rings, so there should be no major problems."

Du Ruhui thought, this is true.

"But Your Majesty, where should this method be tried?"

"Where? Well... let me think about it. Forget it, I will come to Ganlu Palace tomorrow morning to obey the orders, and I will take the action myself!"

"Dear...yes, your majesty!"

Li Erke did not forget about raising pigs.

He read all the historical books and knew that the emperors of ancient times, any wise monarch who had done something would definitely care about the people's livelihood and would not be able to do it every day.

But he had never heard of any emperor who even cared about the people who could eat more or less meat.

Although this method of raising pigs is exquisite, the world is actually settled, and not many people eat meat.

If this method works, promote it

The meat production doubled,

It only reduced the price of 10 meat by three or four points, which is still a luxury for most people and can only taste it occasionally.

But... he, Li Shimin, is to be the first emperor who can make everyone in the world eat meat!
