After Du Lin left Chang'an, he saw the emperor for the first time, but he was not as excited and excited as he imagined, and looked very peaceful.

He said, "Your Majesty, I have read the books of sages for decades, but I am not as good as I have been in Baitu for a year. Only then did I realize that my previous books have been in vain!"

The emperor leaned forward and said, "It seems that you have a lot of insights. Let's talk slowly when you get up."

Du Lin stood up, sat down in the hall, and said, "Your Majesty, I used to be in the court. I always thought that things in the world are easy. As long as I am willing, it is not difficult to govern a county, even if I am willing, it is not difficult to govern a county. But when I came to Baitu, I realized that it is difficult to govern the people and even more difficult to manage academics. When I saw others governing the people, I always felt that this was wrong, and that was not right. I thought that if I changed me, I would definitely arrange everything carefully and not make such mistakes. But it was really my turn that I realized that things in the world seemed easy and difficult to do. Your Majesty said, please do not be useless people, and do more useful things. I remember Your Majesty's teachings and try to do useful things, but I don't know how I did it?"

"What have you done?"

"I came to Baitu and wanted to educate and start a county school first, but few people entered the school. I went to personally to persuade the people to go to school, and only then did I realize that the people were living in a difficult life and were busy with livelihoods and could not eat enough. How could I talk about education? I advised the farmers and the officials to take the lead in plowing the fields, but the results were very little. I didn't understand the reason and asked about the strong fields in the village. I realized that Baitu County had not much cultivated land and the land was barren, and it would not produce much grain even if I advised the farmers. I organized the people to open up land, but they were attacked by the herdsmen, which almost caused chaos. It turned out that the farmers were not as many farmers as the herdsmen's farming and herdsmen's miscellaneous areas in Baitu County. If they were opened, they would occupy the grasslands and affect the livelihoods of the herdsmen. Therefore, the herdsmen opposed me to open up land. I was in Baitu for half a year and failed to do anything, but realized that it was not easy to manage a small county."

The emperor nodded and said, "If you don't understand local affairs, you need to be administrative. No wonder you run into a wall everywhere... what after?"

Du Lin said: "What Your Majesty said is that after half a year of trouble, I realized my mistakes. So I put aside these thoughts and followed the old routines. I went to the countryside every day, from south to north, from east to west, and walked all over Baitu County, stayed with farmers, moved with herdsmen, and worked with the people every day to slowly understand the affairs of the county, and then I found some tricks."

"Your Majesty, the difficulty in Baitu County is due to the struggle between agriculture and herdsmen. The farmers are Han people who moved to live, and most of the herdsmen are Qiang, Hu and Xiongnu people who are affiliated with them. They have different ways of making a living, and each has its own customs. If they treat them together, it will be difficult to implement government orders. Farmers open up land and occupy the grazing land. The herdsmen will also eat the crops of farmers. Over time, the Han and Hu hated each other. However, when the border people are fierce, they will mostly not pass through the government, but gather in the village party and clans, draw their swords to face each other, fight against each other, and kill many people. The county is constantly banned, and it cannot be banned. As a result, the government orders do not leave the county town and the countryside do not accept education."

The emperor said: "You have found the reason. When it comes to the point, according to your opinion, can there be a solution to this matter?"

"Your Majesty, I am foolish in my opinion. In the governance of Baitu, we must first make the people fed and fed, and know the etiquette in the warehouse, and enrich the people first before we can educate them."

"You're right, but how can you enrich the people?"

"Your Majesty, if Baitu County still engages in agriculture and animal husbandry, it will still be a battle between agriculture and animal husbandry, and it may be difficult to enrich the people. I see that Baitu and the surrounding counties have poor land, but there are also fun things, that is, iron mountains and charcoal fields. There is iron mountains to the north of Shangjun, which has a lot of iron storage. There is also charcoal, and the people often pick it up in the severe winter and burn it as firewood. If you can use the people's power to mine iron charcoal from Shangjun, you can not only contribute to the country and make people live in the people, but it is actually a good idea. It is just that the court officials are in the mountains and seas, and this matter cannot be done by one county and one county. I beg Your Majesty to set up iron officials in Baitu and other counties to collect iron mountains so that the things can be used and the people can do their best."

The emperor pondered for a while, then slapped his thigh and laughed, "I'm really sleepy and I have a pillow. This is wonderful, great!"

Everyone looked at him, wondering why the emperor was so happy.

The emperor said: "Premier Ma, take someone to go there personally and work with County Magistrate Du to plan this matter well. If it is true as Du Lin said, then set up an iron official. I not only want to pick iron mountains, but also make large iron smelting tools. This carbonite is also very useful. Using it as fuel to smel iron will achieve twice the result with half the effort!"

The ancients said that carbonite was coal, and Baitu County was near Shenmu County, Shaanxi in later generations. In later generations, it was the place where coal-producing bosses were, of course there was coal.

During the Western Han Dynasty in my country, the application of coal was quite common, and the people used it to burn and keep warm, and even used it to smelter iron. However, due to the iron smelting technology at that time, the utilization rate was not very high.

After hearing the emperor's words, Ma Yuan was very happy. If this matter was done, it would be of great benefit to Shangjun. He enthusiastically discussed the matter of Tieshan and Tantian with Dulin, and decided to set out for Baitu the next day.

There were blacksmiths who specialized in iron smelting in the Hundred and Works Department set up by the emperor. He had always used his modern knowledge to guide the blacksmiths to study iron smelting technology and made great progress. However, there were too many things in China and he had not made any effort to vigorously promote new iron smelting technology.

It was just right to take this opportunity to build a base for iron smelting in Shangjun using new technology to build equipment for the heavy cavalry he was thinking about. In this way, Shangjun had a large horse farm to provide war horses, a good family who was good at riding and shooting as a source of troops, and a weapon manufacturing base to provide equipment, which just formed a complete industrial chain and could build a heavy cavalry team without relying on transportation from other places. This was an unexpected surprise for the emperor.

However, there is a prerequisite for the implementation of this matter, that is, it is necessary to ensure that the iron ore is safe. Shangjun is originally a border county, and Baitu is even north of Shangjun, which is too close to the border. If the Huns go south to rob, the Shangjun iron smelting base will become a base for the Huns' weapons, which will be to build weapons and provide for enemies.

Therefore, the emperor was even more determined to attack Bingzhou. As long as the northernmost counties such as Wuyuan, Shuofang, Yunzhong, Dingxiang were recovered, the county would become an inner county, and weapons could be produced safely.

What's even better is that Baitu County is not far from the Yellow River, and the hydraulic power of the Yellow River can be used to greatly improve the efficiency of iron smelting.

In ancient times, in order to increase the furnace temperature and continuously improve the blowing device, the "shrink" was used at the beginning, that is, using animal skins to squeeze the blowing, which was very inefficient. Later, several blowings were put together and lined up in a row, called shrinking. At the beginning, it was manpower to blow the blowing, which required many people and was very laborious. Later, animal power was used to blow the blowing with the so-called "horse shrinking".

It was not until the Eastern Han Dynasty that Du Shi, the prefect of Nanyang, invented water drainage and used water power. This was a major invention. Because of the generation of water drainage, the efficiency of iron smelting was suddenly increased several times, and due to the large increase in wind power, the furnace temperature was increased, and higher quality iron could be refined.

Now it is not far from the emergence of water discharge in history. The emperor is very confident that he will put water discharge into application a few years in advance, so that the Han Dynasty's iron smelting industry will develop leapfrogly in the short term. Once he leads the heroes in iron smelting, it means that he is in a leading position in the manufacturing of weapons and will naturally be much stronger than his opponents in military terms.
