Li Shimin and a few people followed Xia Hongsheng and Yan Lide into the military aircraft workshop, but there were not many people in the workshop.

"This time of year, they are all busy in their respective shops." Xia Hongsheng said to Li Shimin: "Where is Your Majesty going to look?" ”

"Oh, then I'll just go for it." Li Shimin nodded, then turned around and walked towards a courtyard.

The military aircraft workshop is a whole organization, but because of the different things they do, they are also divided into different courtyards. If you can overlook it from above, you will find that the building structure of the military aircraft workshop is a long wall enclosing the entire military aircraft workshop, and then in the military aircraft workshop, there is a small courtyard enclosed by a wall, like a large square box, which is neatly arranged one by one.

When he entered the courtyard, he heard a clanging sound from inside, and when Li Shimin walked in, he saw a group of people repeatedly forging around a section of iron.

"What are you doing here?" Li Shimin asked, but because the forging sound was too loud, the craftsmen didn't hear it.

"Gotta use this, Your Majesty!" Xia Hongsheng pointed to the side and saw a hollow thing like a cylinder hanging on the wall, which was connected to a rope from the inside. Xia Hongsheng grabbed the rope and shook it, and suddenly heard the thing make a crisp metal sound.

The blacksmiths all stopped at this time, and immediately ran over in a hurry, and hurriedly bowed and saluted in a panic - Li Shimin was not wearing ordinary civilian clothes.

"Hehe, no need to be polite, no need to be polite." Li Shimin waved his hand and said to the blacksmiths who bowed down.

Xia Hongsheng looked at those blacksmiths, and said in his heart that kneeling is not popular yet, which is really good.

"What are you doing here?" Li Shimin asked, "I see that you are forging around this piece of iron, but this iron has not been deformed much. ”

The blacksmiths all looked eager to answer, but they did not dare to speak in front of the emperor.

Xia Hongsheng smiled, named a person, and said, "Don't be afraid, Your Majesty won't blame you for saying the wrong thing!" Zhao Tiezhu, you come to answer His Majesty's words. ”

The blacksmith who was named by Xia Hongsheng suddenly turned red, rubbed his hands excitedly, his voice trembled, and said, "Return, return to Your Majesty...... The little ones are trying to control and adjust the carbon content of the iron......"

With that, the blacksmith stopped, and he was so nervous that he trembled as he spoke.

Li Shimin couldn't help laughing, shook his head, and said with a smile: "Don't be nervous, I don't understand the forging too well after listening to it, and I don't understand it, what do you mean by adjusting the carbon content of iron?" You can rest assured, I would love to hear you talk about it. ”

"Hey!" The man saw that the emperor was speaking very kindly, so he nodded vigorously and said: "Your Majesty, this carbon content means that iron contains a kind of thing, and the Hou Ye taught the little ones that thing is called charcoal." The carbon content is the amount of this kind of thing contained in iron. The more this stuff, the harder and more brittle the forged iron becomes. The lower this thing is, the less hard it will be, but the more flexible it will be. Therefore, the small ones have to find a degree, so that the forged things can be hard, strong enough, not brittle, and tough. Your Majesty, the weapons made by our military machine workshop are very close to this degree, but the small ones have not yet found the best and most suitable degree. At present, the small ones have no way to look at the specific carbon content, and can only infer the carbon content based on the color, toughness, and so on. Moreover, because the carbon content is different, the iron made is also different, and iron with different textures can be used in different places. For example, the steel with the lowest carbon content can be made of small parts to make balls, which are strong and will not break, and the other parts are selected from different materials according to different functions, and combined together to play the best role! ”

Zhao Tiezhu said a lot in one breath.

"I see!" Li Shimin nodded, patted him on the shoulder with a smile, and said with a smile: "What you said is very good, very detailed." ”

Zhao Tiezhu suddenly became excited, oops, the emperor patted us on the shoulder and spoke!

Li Shimin walked around inside and asked a lot of things, and the blacksmiths scrambled to answer, whether Li Shimin understood it or not, at least his attitude was very kind and approachable.

Leaving the courtyard, leaving behind a courtyard of excited and trembling blacksmiths, Li Shimin turned into another courtyard.

As soon as I entered, I stepped on it not on a stone road, but on dirt.

When I looked up, I saw two greenhouses.

"Huh? Is it still possible to farm in the military aircraft workshop? Li Shimin has seen the greenhouse in Jingyang, and he also knows that he can eat fresh vegetables and vegetables in winter, all thanks to the credit of this greenhouse. So recognize it.

"Your Majesty, this is not growing vegetables, this is an experiment on how to improve the saline-alkali land, so that the saline-alkali land can also grow crops." Xia Hongsheng said to Li Shimin.

"Saline?" Li Shimin was stunned for a moment, and then said: "But that kind of wasteland that doesn't produce crops? ”

Xia Hongsheng nodded.

Li Shimin's face froze: "Let's go, go in and have a look!" ”

"Uh......" Xia Hongsheng glanced at Yan Lide, and Yan Lide said, "Your Majesty, here...... There's something bad about it...... Your Majesty, don't go in......"

Before he finished speaking, Li Shimin had already taken a step.

And they had no choice but to follow.

Someone had already bowed down to stop Li Shimin at the entrance of the greenhouse, and his face turned pale and he couldn't stop persuading: "Your Majesty! The little one really didn't dare to teach His Majesty to go in! It's going to dirty Your Majesty! ”

"So that the wasteland can grow crops, but it is a major matter related to the world's agriculture and mulberry, why can't I go in?!" Li Shimin shook his head and said, "You are not afraid of bad smells, let alone Yu I?" ”

Xia Hongsheng and the two of them frequently made eye contacts, and the two of them shivered and opened the door of the greenhouse for Li Shimin.

Suddenly, a sultry heat accompanied by a fishy, ugly, and indescribable unpleasant smell came to the surface, and Li Shimin's face turned white in an instant.

Behind him, the faces of the group also changed, and some people couldn't help retching a few times.

Li Shimin took out a handkerchief, covered his mouth and nose, and walked in without saying a word.

The two people in charge of the greenhouse behind him were about to cry, not afraid, but excited! - Your Majesty doesn't dislike it!

Everyone walked in with Li Shimin, Li Shimin looked down and said, "Yes, it's this kind of soil." There are a lot of such lands in Longyou Road, and there are no crops growing on it, all of them are wasteland! ”

"Not only Longyou Dao, this kind of land is also found in other provinces, if these lands can be planted, then my Datang will add countless cultivated land." Fang Xuanling looked at the land and said in a deep voice. (To be continued.) )
