Guo An didn't know that Zhu Laosi's name as Prince Shangjia directly hung him in front of Lao Zhu, showing a wave.

Moreover, it was also his most defensive brocade guard, which allowed him to avoid the anger of the tyrannical Lao Zhu.

At this time, he was still concentrating on taking ten old craftsmen to run frequently in the Shangzhuang Village Iron Smelting Institute and Wanping County Ya.

A man's greatest hobby is his hobby, that is, he studies all kinds of things, money, food, machinery, women......

And once you study it, you can't stop at all.

Now, Zhu Di has assigned him ten old craftsmen and one to guard hundreds of households, and he can send him what kind of furnace he wants, and how much iron ore he wants, he can be satisfied immediately.

And Guo An only needs to brainstorm, which is nothing more than heaven for Guo An, who has always been lacking in hands-on ability.

The most important thing is that Guo An was also surprised to find that although it was only the beginning of the Ming Dynasty, the iron-making efficiency of these blacksmiths in the Zhu Laosi Iron Smelting Institute was also very high.

It's just that the only pity is that these blacksmiths still have some inertia and like to use an open iron-making furnace, such a big hole, although it is easy to blow air into the iron-making furnace, but the heat in the furnace will definitely not gather.

So, Guo An asked a group of old craftsmen to seal the big hole in an iron-making furnace.

Subsequently, Guo An discovered that these blacksmiths actually used coal to make iron directly, and the quality of the iron smelted in this way would also decline because of the presence of tar.

So, Guo An asked a group of craftsmen to start building a large coke oven for baking coal, and when the temperature is high, it will produce soft dehydrated and degassed coking coal, and then pour it with water, which is good coking coal.

However, then Guo An found that although the amount of iron smelted was more and the quality was better, it seemed that it was not enough for the steel in his impression.

Continue to renovate the iron-making furnace!

Add a hole that can be put into the wicker and used the wicker to hit the molten iron to make steel?

Add two, three......

Alternatively, a pig iron plate is inserted directly from the mouth of the furnace, clamped with tongs, melted and then slowly poured into the wrought iron of the furnace and turned over as if a uniform steel could be obtained.

Still, the pig iron is melted in a furnace, and then the molten iron is soaked in wrought iron to make it fit together, and then the sledgehammer is repeatedly beaten to make it one......

Anyway, Guo An was like encountering a fun toy, and he was immersed in it all day long.

At first, Zhong Huo, the manager of the Iron Smelting Institute, and the ten old craftsmen thought that Guo An, a noble son, had nothing to do in his spare time, and was fooling around in the Iron Smelting Institute.

It's just playing with you.

Even, even Zhu Di shook his head slowly after hearing what Guo An had done in the iron smelting plant all day, and then he didn't pay much attention to it.

However, with the gradual improvement of the iron-making furnace, Zhong Huo and the old craftsmen were shocked to find that under Guo An's whimsical transformation, the iron-making speed was getting faster and faster.

Moreover, the most incredible thing is that sometimes it is not pig iron that is smelted, but hard steel, and even so strong that it can reach 100 refined iron, and sometimes it can exceed 100 refined steel.

As a result, Guo An was surprised to find that these old craftsmen, as if they had eaten some rejuvenation pills, were full of motivation and energy all day long, and they were even more active in research than him.

At the same time, all the craftsmen of the entire Shangzhuang Village Iron Mine began to subconsciously learn some of Guo An's operations under Zhong Huo's arrangement.

Regarding Zhong Huo's stealing of school, Guo An didn't mind.

Anyway, sooner or later, these will have to be handed over to the Shangzhuang Village Iron Metallurgical Institute.

……

And just when Guo An has been going back and forth to the iron smelting station in Shangzhuang Village.

A few letters were sent to Ying Tianfu.

In Fengtian Palace, Zhu Yuanzhang handed several letters in his hand to Zhu Biao with a gloomy face.

"Biao'er, you see, the inspector of Beiping Mansion began to impeach Guo An again, a dog, and he was not good at being his magistrate, so he followed the hundreds of households around the fourth child every day, and drilled into the iron mine one by one.

Moreover, the fourth bastard also specially assigned ten old craftsmen to Guo An, a thief, what are they going to do? ”

"Now, in the court, there are also officials who have begun to play, although it is not impeachment, but it also means that Guo An's son often goes out of office and neglects his duties.

colluded with the fourth child, opened a barbecue shop, opened a farm, and now began to meddle in the iron mine, and compete with the people for profit......"

Hearing this, Zhu Biao's expression moved slightly, looked at Zhu Yuanzhang and said, "Dad, Beiping Mansion is the old four feudal countries. What does the fourth child want a little county to do, and which little county can still resist?

Is this Guo An offending people? Or did the fourth child offend someone? ”

Zhu Yuanzhang looked impatient, "Hmph, how do we know?" Let Jiang Zhen check, but after so long, I still haven't found a clue! ”

"What does Daddy mean?"

Zhu Biao asked tentatively.

"Let's prepare for a few days, let Feng Sheng, Fu Youde, and Lan Yu lead the Jingwei soldiers to Beiping, and the soldiers of the Dao will practice on the edge of the ditch."

Zhu Yuanzhang said, "Since the fourth Yanwang, and Guo An, the magistrate, like ironmaking so much, and they have been sued, let's ask them to prepare iron tools for our 10,000-strong army."

In this way, the mouths of those officials in the DPRK and China can also be stopped. ”

"Hiss......"

Zhu Biao couldn't help but take a cold breath, "Dad, the fourth child has only been in Beiping Mansion for five years, and during this period, there are still three guards of Yanshan to support, can the fourth child take out so much family funds?" ”

"Hmph, we don't care!"

Zhu Yuanzhang said coldly: "The fourth child doesn't have so much family background, so you can buy it." We have heard that he only copied the homes of a few corrupt officials in the palace a few days ago, and copied out more than 100,000 taels of silver.

Now, we heard again that the fourth barbecue shop can still earn more than 10,000 taels of silver every month.

Fuck the thief, this bastard boy is starting to get rich now! ”

"In that case, then listen to Daddy. However, is Dad preparing to conquer the Northern Yuan? ”

……

Wanping County.

Guo An, the magistrate of the county, took Wang Zhen, the historian, and a group of scribes, all stood at the gate of the county office.

"Wanping County Ya and Shan Congratulations to the Sect Experience!"

"Guo County is courteous!"

Beiping Bu Political Envoy Shi Zongzhi hurriedly returned the salute to Guo An slightly, he didn't dare to show his hand to the henchman of King Yan.

"Zong experience, please!"

"Guo Zhixian, please!"

Although he was surprised by the politeness of the political envoy, Guo An didn't think much about it, but politely welcomed Zong Zhi and the two officials behind him.

As for the scribes in Wanping County, they looked curiously at the two middle-aged people behind Zong Zhi from time to time.

They had already heard the news that those two would be the new officials of their Wanping County, the county lord and the lord.

It seems that His Royal Highness King Yan personally went to the political envoy to come!
