After Handan was defeated, it was not a big deal for most ordinary people, but the food rations at home were stolen.

According to Zhao Yan's instructions, Han Sheng restrained the bandits below. After attacking the city, he did not set fire and pushed the wall.

In general, the vitality is still relatively well preserved. In addition, the people who have been brought along along the way, the people in Handan have reached 130,000, including men, women, young and old, and about 40,000 young and strong.

Handan contains a wide variety of mineral resources. Later generations were China's famous coal and high-grade iron ore production areas. It has rich "two blacks" - coal, iron resources, coal and iron ore reserves reached 4 billion tons and 550 million tons respectively. It is known as the modern "steel city" and "coal capital". Among them, the coal reserves are rich, the coal species are complete, and the coal quality is good; the iron ore is of high grade and there are few harmful impurities, so you can choose a good surname.

It has coal and iron, and the iron ore has a high taste, which is definitely an ideal smelting base. Most of the iron ore in China has a low taste and very few iron ore.

The staff who followed the army began to intensively resettle the people. Zhao Yan took his people to inspect the mining area. 90.8% of the iron ore in Handan was concentrated in Wu'an, and the remaining ones were distributed in Shexian County.

Zhao Yan inspected the iron ore in Wu'an. Wu'an is a small county. It was conquered by bandits in six years and has become extremely depressed. The miners in the mining area were also taken away by bandits, so Zhao Yan took it directly.

After visiting Shexian for three days in Wu'an, Zhao Yan determined to set up seven mining areas, and the iron ore in these seven mining areas is easy to mine, including the fifth in Wu'an, the second in Shexian, and three coal mines in Handan.

These eight mining areas were arranged to go to mine, and each person was given one tael of silver a month. This treatment made more than 100,000 people concentrated in Handan very enthusiastically sign up.

Finally, he chose 20,000 young and strong people and entered the mining area to start mining. It can be imagined that Handan will be a good place for labor reform in the future. So many iron ore and coal mines require a lot of labor.

Directly use gunpowder to fry mine, which can improve mining efficiency. A blast furnace with simple technology is used for iron smelting. In the Great Leap Forward era, there are such furnaces everywhere, and there is no need for any technical name.

Coking uses severely polluted local methods. Later generations have cracked down on local methods every day, but there are still many people who have refined them. The economic benefits seem to be very high. It is a good way for ordinary people to get rich and get rid of poverty, but there is a risk of being banned at any time.

In terms of steelmaking, Zhao Yan has not yet developed a flat furnace, and the flat furnace is not made of coke. Therefore, Zhao Yan can only use the Pudrin method, also known as the steel frying method.

Before the emergence of the open furnace, the first thing that was developed was the British steel speculation method. Some people say that this technology appeared in China more than a thousand years ago, and I don’t know whether it is true or false, but it is true without large-scale promotion.

The Pudrin method used to produce large-scale iron in the Middle Ages. It is also known as the stirring method. The structure of the Pudrin furnace is similar to that of the open furnace, but there is no lower heat storage chamber. The long flame formed after the fuel is burned is sent into the furnace, and the pig iron is heated by the reflection of the furnace top. The bottom of the furnace is built with iron oxides. Due to the excess oxygen in the flame and the large amount of oxygen in the furnace bottom, the carbon and phosphorus in the pig iron are oxidized and removed. However, the temperature of the Pudrin furnace is only about 1400℃. After the carbon in the pig iron is removed to a certain extent, the melting point exceeds the furnace temperature and the metal is in a semi-solidified state. It is necessary to rely on manpower stirring to make the smelting continue.

However, since the furnace bottom and slag contain extremely high iron oxide, the carbon can be removed to a very low level and become cooked iron; then after repeated forging, the iron oxide slag in the cooked iron is extruded and used as materials.

The Pudrin method was the main production method before the emergence of modern steelmaking methods, and it reached a considerable production scale. In the mid-18th century, the railway paved with Pudrin iron reached more than 70,000 km. However, due to the fundamental weakness of semi-solidified smelting, poor working conditions and poor quality of hard iron, the Pudrin method was quickly eliminated after the birth of Bessemai method.

The method of stir-frying steel is to first develop cooked iron and then use manual forging to make steel, so it requires a lot of manpower. Although the Bessemai method is better than the method of stir-frying steel, it requires adding manganese. Zhao Yan's chemistry is just average, and it is okay to teach students, but if he wants to find manganese, his eyes will definitely turn black.

Anyway, the Ming Dynasty had nearly 100 million people, so there would always be no shortage of manpower.

As long as these technologies are implemented and Handan is built into a steel base, it will definitely make Zhao Yan's strength a qualitative leap.

The plate armor can be directly made of steel, and the defense can be raised to another level.

Before the appearance of open furnace steel, you should not think about it. You can only continue to use cast iron and copper. Before the appearance of open furnace steel, the quality of the steel cannot be used as open furnace steel, and it is mainly easy to break.

...

Just as Zhao Yan was planning the steel base, the soldiers below suddenly came to report that the governor of Yunyang Lu Xiangsheng was coming, and Zhao Yan was so scared that he rolled and crawled out.

The thieves were disarmed, why did Lu Xiangsheng come here for? Zhao Yan hurried out to arrange the situation and thought to himself.

The arrival of Lu Xiangsheng made Zhao Yan extremely guilty and quickly called Han Sheng over. The two of them had a good attitude, so they hurriedly brought a hundred personal guards to meet Lu Xiangsheng.

A group of people appeared in sight from afar. Zhao Yan picked up the telescope and saw a man in his thirties in the army wearing a regular governor's uniform walking on a horse. It should be Lu Xiangsheng.

Lu Xiangsheng was the most capable civil servant among the civil servants in the late Ming Dynasty who dared to fight. Unfortunately, he was alone and eventually died in isolation and helplessness. During the Wen and Jie period, they were even bombed.

Facing such a great man in history, Zhao Yan was a little nervous, and he was more afraid of being insulted by the thief.

But if you think about it carefully, there is nothing to be afraid of. It is generally unlikely to be missed. Even if you are seen, you can deny it.

If you have money and someone has food, there is no need to be afraid of the court. You can be more unrestrained.

Thinking of this, Zhao Yanxin was a little calmer.

Five or six minutes later, the army in the distance came not far away from Zhao Yan. Zhao Yan led his men to meet him, and the army stopped immediately.

"Secretary General Denglai, please see the governor." Zhao Yan took off his horse and bowed his hand to see.

Lu Xiangsheng immediately looked at the young man in front of him, and couldn't help but look at him again and again, a little dazed, and then said for a while: "Are you Zhao Yan?"

"It's the lower official." Zhao Yan replied.

"How much does this year?" Lu Xiangsheng asked again.

"nineteen."

"I didn't expect to be so young. I heard that you were a scholar, why did you abandon your pen and join the army?" Lu Xiangsheng felt a little incredible. At such a young age, why did he raise a soldier?

"My father was harmed by Kong Youde's rebellious soldiers. He only read the books of sages for ten years, but he had no power to destroy the thieves. He felt helpless. He had to abandon his pen and join the army and train the soldiers in the village to protect the territory and the people." Zhao Yan immediately made up an excuse. Could he still tell him that the court was going to be over, the Qing Dynasty was about to enter the pass, and he practiced some troops and horses to protect himself...

"Well! It's better to abandon your pen and join the army, and you won't be able to talk nonsense and talk, sit and whistle and paint promises." Lu Xiangsheng nodded and asked, "Why are you expressing your words?"

"The Governor of Shandong gave the senior official a word of "staying firm" Zhao Yan said.

"I heard that the monkey invaded Handan and set off on the 19th. He rushed to the night. However, the journey was far away, and he was finally one step late. I don't know why he was a step late?" Lu Xiangsheng asked suddenly.

"This... the heads of the troops in the lower government army went out to Shandong to fight. Most of the soldiers were unacceptable to the land and water. In addition, there was no place to supply along the way, and the baggage they brought was too heavy, so they were one step late." Zhao Yan said vaguely.
