In addition to the blacksmiths, the stonemasons and carpenters are no better, there are drawings sent every three or five times, at first they feel relaxed, but then it becomes more and more complicated, so that they are a little unbearable, the original few old craftsmen can easily complete the task at hand, but now they have to get together, each with their own housekeeping skills to continue to communicate.

At this time, Zhu Di, who was out of the city, was full of interest, let the horse run wild on the official road, he rode a good horse under his seat, and his riding skills were amazing, Hao Fenglou was not able to catch up, so he simply ignored him, and slowly put the horse at his own pace, but a few guards were red-eyed and galloped to catch up.

Zheng He couldn't bear it anymore, so he simply walked with Hao Fenglou and said, "Senior brother, what does Your Majesty want to see?" ”

Hao Fenglou didn't hide it from him, he knew that Zheng He was the henchman of Zhu Di's henchmen, and in history, Zheng He did participate in the investigation of Jianwen's whereabouts, but he couldn't tell it all, he just said: "This matter is not small, and I can't say it clearly, you will know it then." ”

Zheng He smiled slightly: "The master wants to move in a few days to live with the senior brother, our family is a eunuch, we can only be in the palace, we can't serve the master and his old man, and the senior brother will have to take care of it more in the future." ”

Hao Fenglou glanced at Zheng He and said, "Master...... "Brother ......" When talking about his junior brother, Hao Fenglou always felt a little tongue-twisting, and he was very unaccustomed to saying: "Senior brother drives around day and night, I think it's very hard." ”

Zheng Hewan smiled and said: "It's hard work, in fact, serving the emperor is like a boat, going against the current is a violation of the scales, but if you go down the river, you don't have much to worry about." 陛xià is the male lord. thinks differently from others, and understands his temper. In fact, it is easier to get along, and the master said that the senior brother is a person with wisdom roots, and he thinks he understands it more thoroughly than me. ”

Hao Fenglou glanced at Zheng He deeply, as if he had some understanding, and couldn't help but smile: "Your Majesty has gone away, let's catch up." ”

Zheng He nodded.

The personalities of this pair of brothers are extreme, one is quite right, and the other is full of ghost ideas. But there is one thing in common, they are all smart people.

Hao Fenglou and Zheng He caught up with Zhu Di, Zhu Di stopped at his horse, his broad shoulders trembled slightly, and said, "It's a shame that you are still young people, and even I am not as good." ”

Hao Fenglou said with a smile: "Your Majesty, I arrived at the camp in a month or two before." ”

Zhu Di looked around with satisfaction. I couldn't help but nod and said, "This place is good." ”

Further down, the outline of the camp is revealed.

Zhu Zhiling saw the strange situation, confirmed that it was Hao Fenglou and Zhu Di who arrived, and hurriedly brought two cronies and warriors to greet him.

Zhu Di glanced at Zhu Zhiling with a smile and said, "Thank you for your hard work, you don't have to be polite." Let's go, take me to see it, and don't reveal my identity. ”

The group dismounted, because the strong men ran in a long group and did not come back for a while. Zhu Di simply went to see the others, and he first went to the settlement in the east. Seeing that many blacksmiths were smelting iron in the furnace shirtless, he asked Hao Fenglou with interest: "Why, Shenwuwei still has to make iron by himself?" ”

Iron smelting is actually harmless, but the Ming Dynasty did not allow private forging weapons, and most of the blacksmiths were made into craftsmen.

Hao Fenglou said: "Your Majesty, Shenwuwei is no better than others, if you ask the military department to transfer ordnance, I am afraid that it will make people suspicious." Moreover, the equipment used by Shenwuwei must be different from other guards, so Weichen had the courage to raise some craftsmen and let them make some preparations for the future according to the characteristics of Shenwuwei. ”

Zhu Di didn't see the guilt, but just smiled and said, "Do you want to make special weapons?" ”

Hao Fenglou said: "That's right, after all, they don't expect the Shenwu Guards to charge into battle, ordinary swords don't mean anything to them, so Wei Chen doesn't plan to give them long blades, but some weapons that are easy to hide are more suitable for them." ”

Zhu Di nodded and said, "Yes, that's the truth." ”

The blacksmiths learned that the 'master' was coming, and they came out to meet one by one, who knew that Hao Fenglou's face did not look like a precious master, so everyone stepped forward together, saluted Zhu Di, and said in unison: "Meet the master." ”

Zhu Di was provoked to laugh, pointed to an old craftsman led by him and said: "I am not your master, your lord is here." ”

The craftsmen were suddenly embarrassed, and they had to salute Hao Fenglou again.

Hao Fenglou was not polite, nodded and said, "I don't know if the drawings I handed over to you can be produced in a hurry?" ”

The blacksmiths were suddenly embarrassed, and looked at each other one by one, and the old blacksmith smiled bitterly: "Old ...... Young master, the villains have forged a few times, although they have improved a lot, but they are still ......"

Hao Fenglou interrupted him and said, "What's the problem? ”

The blacksmith replied, "Fire." The heat is insufficient, and the impurities cannot be removed, so it cannot produce purer pig iron, although it is forged into steel, but it is congenitally insufficient, so it ......"

Hao Fenglou smiled slightly: "I also expected that it was a problem of heat, in fact, the foundation of forging is ironmaking, otherwise no matter how good the skill is, without good iron, it will be in vain." But the root of iron smelting is the heat, and whether the pig iron is smelted well depends on whether the heat is enough, but why don't you use the bellows? ”

The blacksmith said, "Yes, but it's still a little worse." It was made by those carpenters, and it really works, but ......"

Hao Fenglou said: "You take me to see the direction of the wind." ”

The blacksmiths led Hao Fenglou to the thatched house, and Hao Fenglou saw that there was a bellows in the furnace, the bellows were very ancient, made of wood and cowhide, Hao Fenglou squatted down and looked at it, and then said: "Let the carpenter improve the wind direction and increase some wind power." What do you use to make a fire? ”

The blacksmith said: "Naturally, it is charcoal, but to be honest, the villain has a saying, I don't know whether to talk about it or not, this iron smelting is not easy, and the cost is huge, to smelt a pound of iron, not only ten catties of iron and stone, but also seven catties of charcoal, the cost is quite a lot, young master, we have wasted a lot of money." ”

Hao Fenglou smiled, he suddenly realized a problem, in this era, the value of iron is very high, to practice a pound of iron not only requires a large amount of iron ore, but also needs nearly ten catties of charcoal, to burn ten catties of charcoal, and people need to cut down trees and burn them into charcoal, which costs a lot of manpower and material resources.

It is precisely because the production of pig iron is not high and the cost is extremely high, so iron is not only an extremely important military resource, but at the same time, it has become a circulating currency, and iron can be turned into money, which also lies in its value.

Hao Fenglou suddenly had a bold idea, what if he could reduce the cost of iron making a lot? Once he had this thought, Hao Fenglou finally realized what was called the advantage of a traverser.

But he didn't show his face, there was no need to rush now, and let these craftsmen slowly become proficient.

The conversation between Hao Fenglou and the blacksmith, Zhu Di, who was standing on the side, did not interrupt, and when Hao Fenglou came out of the hut, Zhu Di pursed his lips and smiled: "What, you are also interested in ironmaking?" ”

Hao Fenglou said: "It's not interesting, anyway, I'm idle, I'm idle, and occasionally ask them for advice." ”

Zhu Di couldn't help but sigh: "I don't like literati, do you know why?" They are too noble and always refuse to let go of their bodies. However, you have a thousand households and blacksmiths to discuss these inevitably a little lost their identity, come to think of it, you have such a responsibility at a young age, and it is inseparable from this. ”

Zhu Di has a deeper understanding of Hao Fenglou, a young man is always unexpected, Zhu Di always felt incredible in the past, but now he is in the tube, but he suddenly finds that this guy can always be unexpected, and he wants to be inseparable from these details of life.

Zhu Di said: "Do you want to make good iron?"

Hao Fenglou said: "Your Majesty, Wechen heard that the Japanese are the best at refining knives, and the knives they make can blow hair and break hair, so Wechen also wants to try it." ”

Zhu Di said: "If it is refined, remember to send a good knife." What do we look at next? ”

Then, Hao Fenglou took Zhu Di to the study room.

This bookstore is the largest building in the whole camp, in order to prevent moisture, so some bricks and tiles have been added one after another, when everyone entered, several clerks hurriedly got up to salute the two, thinking that someone had already informed them in advance, so this time there was no oolong who mistook the owner.

Zhu Di stepped forward with a smile and said, "You guys are transmitting documents, but you don't know what kind of documents are being transmitted?" He walked up to a case, picked up a piece of letterhead, unfolded it very unceremoniously, and was soon stunned.

Because there are only numbers in the letterhead, there are no Chinese characters at all, and the whole letter is densely packed like this, starting with 5792, and then 7632, Zhu Di doesn't even know any of these numbers, let alone the meaning behind the numbers.

Hao Fenglou hurriedly stepped forward and said: "This is a number invented by the Tianzhu people, and Weichen saw that it was used for convenience, so he let the clerks learn, fortunately, it is very simple, 5 is Wu, 1 is one, that is, you can be familiar with it in a few days." ”

Zhu Di couldn't help but nodded: "It's really convenient." It's just, what does this five-seven-ninety-two mean? ”

Hao Fenglou said: "This is a code. ”

Zhu Di became interested and said, "You go on." ”

Hao Fenglou said: "The official document is delivered, in fact, it is nothing. However, Shenwuwei is different from other yamen, and what he is most worried about is that he is afraid of leaking news, and if the official document is passed on and intercepted, it is very likely to be completely exposed. However, in the future, a large number of people will be sent out, and there will be a large number of documents, so Weichen thinks that a secret code must be set in the documents, even if it is discovered and intercepted, it is useless. ”

Zhu Di was confused: "Do you want to make a code for these numbers?" But how does the person who receives the letter know what this figure means? ”
