As soon as Li Min's wedding date was announced, officials from the Ministry of Etiquette came to his door the next day to train him on wedding etiquette. However, just then Concubine Yang summoned him to the palace, and her mother-in-law taught him a lesson for a long time, which was nothing more than telling him that in the future

We are all married people, so we must be steady in our conduct and behavior, and we can no longer act as recklessly as before.

The next day, officials from the Ministry of Rites came again, but Li Min was dragged to a restaurant by Cheng Hualiang and his gang to celebrate. Speaking of which, these guys were really crazy. Once they went to the restaurant, they would not leave. When they were tired, they would just leave.

He slept inside, woke up and continued drinking, and ended up celebrating in a restaurant for three days and three nights. It wasn't until one of the guys got alcohol poisoning that the comedy almost turned into a tragedy, and the carnival had to be ended.

Before Li Min could wake up from the alcoholic carnival, the persevering official from the Ministry of Etiquette came again. However, God destined his mission to be extremely difficult. This time, the Lady's Mansion of Sui State sent someone to look for Li Min. Of course, Li Min could not

I didn’t want to go, so I could only get on the carriage and drive away under the resentful eyes of the official of the Ministry of Etiquette...

In the next few days, Li Min had no time to do any etiquette training. People close to him, such as the King of Hejian, the King of Jiangxia, and Li Ke, lined up to have a banquet with Li Min.

Here are some things that Li Min should pay attention to in his married life. Princess Hejian and Princess Jiangxia even told Li Min to treat his bride well and not to have any grudges because of her low background. Although their worries are all unnecessary.

However, Li Min was very moved. Being able to say these words to him showed that people really regarded him as a close junior.

After working for more than ten days, Li Min was finally free. The official from the Ministry of Rites was extremely excited, thinking that he could finally get the job done, but he didn't expect that someone from the Ministry of Works would intervene.

They even sent someone to invite Li Min, saying that they were following Duan Lun's order to help the Ministry of Industry improve the technology of iron and steelmaking.

Now the officials of the Ministry of Rites have quit their jobs, thinking that I have been here every day for the past ten days or so. The Ministry of Rites could not afford to offend the people who came to invite Prince Liang in the past, so they did not dare to stop them, but now your Ministry of Works actually wants to come too.

Stealing people? We are all at the same level, so our etiquette department doesn’t need to be afraid of you. We have to come first and then follow up on everything we do, okay?

The official from the Ministry of Rites felt dissatisfied and immediately started a quarrel with someone from the Ministry of Works. The official from the Ministry of Works also followed Duan Lun's strict order and told him to invite Li Min over no matter what, so he refused to give in.

The two officials started to quarrel more and more fiercely in Li Min's main hall. In the end, it was not known who made the first move. Anyway, the fight between the two turned from a civil fight to a physical fight.

Although both of them were scholars, the officials from the Ministry of Industry were out in the wind and rain every day. Their physical fitness had already been trained, so with three punches and two kicks, they took care of the weak scholar from the Ministry of Etiquette. Waiting for Li

When Li Min heard the report from his subordinates and came out to break up the fight, the poor official from the Ministry of Rites had already been carried away by the doctor. In desperation, Li Min could only follow the people from the Ministry of Works.

Last time, because of the patent law, Li Min promised Duan Lun to help the Ministry of Industry improve the technology of iron smelting and steelmaking. As soon as the patent law was passed, Duan Lun wanted to find Li Min to fulfill the conditions he had promised him, but who knew

It happened again that Li Min was about to get married. He also knew that Li Min must be extremely busy, so he resisted not going to see Li Min for more than ten days. It was not until today that he received the news that Li Min had nothing to do today. Only then did he

Send someone to fetch him.

Duan Lun had been waiting for Li Min at the Ministry of Industry for a long time. As soon as he saw him coming in, he immediately took Li Min to a large workshop behind the Ministry of Industry. This workshop was a bit special because the craftsmen inside were all of high quality.

Officials. They are all technical officials who were promoted to officials because of their superb skills. The content of their work is to use their superb skills to improve the current crafts or technologies. They are equivalent to the research institutes of later generations. Li Mindi

The first time I came to the Ministry of Industry, I knew about the existence of this large workshop. However, due to confidentiality reasons, even the prince could not enter without Duan Lun's permission.

After entering this large workshop, Li Min looked around curiously and found that it covers a huge area and is divided into many areas according to different industries. For example, Li Min saw papermaking, construction, weaving and dyeing, and ceramics.

Wait, there are as few as three or four people in each area, as many as dozens of people, either busy or discussing, it looks like a very busy scene.

The smelting area that Li Min and the others were going to was in the center, quite far away. Li Min saw several tall furnaces standing there, and people seemed to be walking around on them. Li Min knew that they were used for smelting.

Iron blast furnace and blast furnace iron-making technology had already appeared in the Han Dynasty. By the Tang Dynasty, it had developed into a very mature iron-smelting technology. Li Min could do very little to improve this technology. The key is to improve the current steel-making technology.

Improvements in technology.

"Chief Jiao Xing of the Ministry of Industry, please see Mr. Shangshu!" The director in charge of the smelting area saw Duan Lun and immediately ran up to salute. This boss Jiao had gray hair and looked to be in his sixties. He may have been exposed to smoke all year round.

Huo Liao, his two cloudy eyes were red, and his back was slightly hunched, but he seemed to be in good spirits.

"Master Jiao, you don't need to be polite!" Duan Lun said with a smile, then pointed at Li Min and introduced, "This is the famous Li Liulang, King of Liang. He is here to help you improve the smelting technology."

When he heard that the other party turned out to be King Liang, Chief Jiao was startled and immediately bowed and saluted. However, when he heard that Li Min had come to help them improve their smelting technology, Old Jiao raised his eyebrows subtly, and there was a hint of mystery in his eyes.

There was a look of disdain on his face, but it didn't show at all on his face.

"Mr. Jiao, can you show me the blast furnace used for iron smelting first?" Li Min had a clear view of the other party's reaction, but he did not criticize it. Instead, he pointed at the blast furnace and said with a smile.

Hearing Li Min's words, Master Jiao was stunned for a moment, then smiled and said: "If Your Highness is interested, I would be honored to do so!"

Manager Jiao led Li Min and the others to the blast furnace. As soon as they approached, Li Min felt a wave of heat coming towards his face. Looking at the billowing smoke above the blast furnace, it looked like the fire inside was burning brightly.

"Your Highness, this is a blast furnace for iron smelting. We stack fuel, iron ore, and limestone layer by layer. After igniting the fuel inside, we use a blower to blow air from the bottom. When a certain furnace temperature is reached, the ore

The iron inside is heated and turns into molten iron. When it flows out from below, it is very common pig iron. Now the iron is being made with the coke that was just delivered. The coke is used as a new fuel, so what we have to do now is to find out its nature.

, to facilitate large-scale application in the future." Chief Jiao did not know that the coke was made by Li Min in front of him, so he introduced the coke in such detail.

"Haha, Master Jiao, you may not know that this coke is the masterpiece of His Highness." Duan Lun said with a smile after hearing what Master Jiao said.

"Oh?" Manager Jiao glanced at Li Min hesitantly. He had also heard of Li Min's name and knew that the prince was good at making tools, but ironmaking was different from other things. This was all real experience, wasn't it?

You can do it if you are smart, but considering Li Min's age, it is impossible for him to have any experience in iron-making. That's why he looked so disdainful when he heard that Li Min came to guide them in iron-making.

"Your Highness is a talented person. This little old man didn't know that the coke was made by Your Highness, which makes you laugh." Master Jiao said with a bow. As a craftsman who has been smelting iron all his life, he certainly knows the impact of the appearance of coke on iron making.

The importance is that coke has good air permeability and can support the heap pressure of a large amount of iron ore. The most important thing is that using coke to make iron can increase the furnace temperature, resulting in better iron quality and higher iron output.

And unlike coal, which makes iron too brittle, it can be said to be the best fuel he has ever seen in his life.

"Haha, it doesn't matter!" Li Min saw that Chief Jiao immediately became more respectful towards him, and felt quite proud in his heart. The respect just now was just because of his status as a prince, and the respect now is respect for his talents.

These two kinds of respect have completely different meanings.

"Mr. Jiao, these should be used for blasting, right?" Li Min pointed at the row of skin bags next to the blast furnace. These skin bags were expanding and contracting in a reciprocating motion. The air outlet was connected to the bottom of the blast furnace with an iron pipe.

And those that provide power for the skin are several horses.

"Your Highness, this thing is called a water drain. It is indeed used for blasting. Because it is usually driven by water power, it is called a water drain. However, because the blast furnace here is only used for experiments and does not actually produce iron.

, it is not used much, and there is no water source around here, so it is driven by horse power, so it can also be called a horse platoon." Chief Jiao stepped forward and introduced.

"Oh~, I have a question to ask Mr. Jiao. When making iron, is the higher the temperature in the furnace, the better?" Li Min said with a smile. Although there is something he can improve in blast furnace iron making.

There are not many, but there happens to be one right in front of me, and with this improvement, it can also shock the craftsmen like Master Jiao and let them know their talents, so that they can better direct them in the subsequent steelmaking.

"Uh~" Manager Jiao was stunned. He was not used to Li Min's leaping thinking. Just now he asked about the water drain. Why did he suddenly go to the furnace temperature? But after all, he has been smelting iron all his life.

matter, so he opened his mouth on these issues, "Your Highness, if you don't consider the burning resistance and cost of the furnace, the higher the temperature of the furnace, the better. For example, the coke you made, your Highness, has its greatest advantage.

One is that it burns at a higher temperature than charcoal and is more resistant to burning."

After hearing the other party's answer, Li Min laughed and said: "Mr. Jiao, since you know that the higher the temperature, the better, why do you still blow cold air into it? Isn't it like blowing cold air into a pot of boiling water?

Pour cold water, how can it possibly make the furnace temperature inside reach the highest level?"
