The Lone Star of the Tang Dynasty

Li second-hand held this wrought iron cheats, his heart was surging, and he was amazed by Li Changge's intelligence.

Empress Eldest Sun also asked expectantly: "Is this our song?" Li Er nodded proudly and affirmed that looking at the world, he is the only one who can have such extensive knowledge and uniqueness.

Empress Eldest Sun had a pleased smile on her face, and secretly praised her children in her heart.

Seeing this, Du Ruhui knew the importance of this method, so he requested: "Your Majesty, the minister wants to take a closer look at this method of forging iron so that it can be put into practice as soon as possible. "

Li Er agreed with his words and ordered Du Ruhui to study it first, and handed it over to the Ministry of Industry for implementation in due course.

Du Ruhui took the booklet and first noticed that its binding was unique, although it came from the countryside, it could be seen that His Royal Highness had intentions. When I opened it, the fly-headed small block jumped on the paper, and the handwriting was as clear and sharp as a knife and an axe. Du Ru secretly claimed to be surprised, but he also suspected that these were not ink pen writing, but traces left by some special tool.

However, when he read deeply, he found the content difficult to understand. Each page is illustrated to the smallest of centimeters and detailed data descriptions, but the more informative it becomes, the more dizzy Du becomes. I can't help muttering in my heart, on weekdays, young people are reprimanded by their elders for not studying, but today, it's he, a seasoned old minister, who is a little powerless in the face of this work.

The professional terms such as "metallographic" involved in it, Du Ruhui is extremely unfamiliar. When Li Er asked him about his understanding of this method of wrought iron, Du Ruhui was embarrassed and admitted that he could not understand the mystery.

Li Er was quite surprised when he heard this, it stands to reason that Du Ruhui, as the secretary of the military department, should have some understanding of weapons manufacturing, but now he is confused about this. He suspiciously grabbed the booklet and flipped through it himself, and at this glance, his face instantly became complicated. It turned out that the iron-forging techniques recorded in this booklet were not only broad and profound, but also contained many unheard-of changes in skills, so much so that Li Er felt that it would not be too much to do it if it was not iron-making, but alchemy.

Just when Li Er was having a headache with this, he found some relatively straightforward content on the last few pages of the booklet: how to add charcoal and sulfur accelerant according to the hour, how to use a waterwheel to drive a large forging hammer instead of manpower, and even attached a detailed design drawing. Li Er smiled heartily and nodded at Du Ruhui: "Keming, you only see the part that discusses the principle in the front, which is the 'Dao', and the specific operation method is the 'technique' that follows." "

After listening to this, Du Ruyan revisited the booklet, and really found an easy-to-understand and practical forging process in the back. He sighed from the bottom of his heart: "Your Majesty's knowledge is really profound, first investigate its roots, and then achieve its application, which is a realm that many well-educated people cannot reach." "

Although Empress Changsun did not understand the specifics of wrought iron, she saw that her husband and important ministers praised her son's works, and her pride and joy were overflowing.

Just when everyone was rejoicing, Du Ruhui suddenly caught a glimpse of a few scribbled handwriting at the end of the page, and it was written: "Fool forging steel method, complete" and a comment: "Li Changge, you remember, in the future, you will talk to people about fool plans, who can understand those principles!" Du Ruhui laughed dumbly, Ge'er was really a ghost, and regarded them as unfathomable wrought iron techniques, which were ordinary and even clumsy methods in his own eyes.

Despite this, this set of wrought iron techniques was undoubtedly crucial to upgrading the equipment of the Tang army. Du Ruhui confidently reported to Li Eryu: "Your Majesty, the minister has preliminarily mastered the method of forging iron with His Highness. Li Er was overjoyed when he heard this, and immediately ordered to gather the top blacksmiths and prepare to use the new method to create the best armor weapons for the Xuanjia army to use.

Just when Du Ruhui was about to retreat, Li Er stopped him again......

seemed to think of another important matter, so he said: "Du Qing, there is one more thing that needs to be supervised by you, that is, pig raising." "

Du Ruhui was slightly stunned, although the matter of raising pigs is not a major policy of the country, it is not unconsidered, especially the pig breeding method mentioned by Li Changge involves drug epidemic prevention, which made him hesitate for a while.

"When it comes to plague prevention, I think about it, and the key is prevention, not cure. Keeping the pen clean and rearing in isolation should greatly reduce the risk of disease. Li Er explained confidently.

Du Ru thought about it carefully, it is true, prevention is the best policy.

However, Du Ruhui asked again: "Your Majesty, has the location for the trial implementation of this new law been chosen?"

Li Er thought for a while, and after a while, decided to take matters into his own hands: "Don't worry too much about the location selection, tomorrow morning you will all go to the Ganlu Hall to listen to the order, and I will personally supervise this matter." "

Li Er's obsession with pig raising is not a whim. He has read through the annals of history and knows that the wise men of the past dynasties have all cared about the people's livelihood and suffering, but now he wants to go further, not only to care about whether the people can be fed and clothed, but also to pay attention to whether they can eat meat regularly. Once that sophisticated pig farming technique is successfully promoted, meat production is expected to double, even if the price of meat drops by three or four cents, it is still a luxury for most people, but he Li Shimin vows to become the first emperor to make meat affordable for all people in the world.

At the same time, he was also concerned about whether the penicillin mentioned by Ge'er could be produced on a large scale and spread throughout the country as soon as possible, which would not only be related to the development of the pork industry, but also a major leap forward in the medical field.

At dawn the next day, Li Shimin was dressed in micro-clothes and appeared outside the palace gate with Du Ruhui, Fang Xuanling and the unexpected Li Jing. Fang Xuanling and Li Jing were confused, while Du Ruhui looked a little embarrassed. "What's going on?" Fang Xuanling asked tentatively.

"Naturally, I want to do the right thing! As the Son of Heaven, how can it be that I am calling you here to talk about elegance? Pharmacist, you will lead the way, and we will go to the barracks!" Li Er's tone was resolute. Li Jing was even more puzzled, as a military general, how could he be involved in such a seemingly inconsequential matter as raising pigs?

"Your Majesty means ......" Before Li Jing's voice fell, Li Er had clearly instructed, "You will understand when you go." Du Qing, are those piglets ready?".

"Back to Your Majesty, the piglets are all in place. Du Ruhui replied.

"Then let's go!" the group of horses' hooves sounded and marched in the direction of the Chang'an military camp. In fact, it was not for nothing that Li Er asked Li Jing to lead the way, just because the Chang'an military camp was under Li Jing's jurisdiction, although at the moment Li Jing was still confused and didn't understand why he had to go to the army early in the morning to feed the pigs.

"Brother Du, what is the ...... of Your Majesty's move" Li Jing couldn't help but ask again.

"Pig farming. Du Ruhui replied briefly.

Li Jing was stunned for ...... moment
