In all dynasties, iron has been one of the most important resources, and it is widely used in agricultural production or military purposes.

However, the skill of iron making in ancient times was relatively low, and the cost was extremely high, so the price of iron remained high, so that iron could become a currency for circulation. In most areas, farmers did not even have iron plows or shovels.

Therefore, iron is a good deal, but it is not easy to trade iron tools. Although there are blacksmiths and small-scale iron smelting, it is not widely available.

However, Zhu Di didn't mind this, so he agreed happily, and then said: "In a few days, I will issue an order. You and Zheng He will handle other matters together."

Whenever salt and iron are involved, eunuchs must be involved. Hao Fenglou recognized this. Besides, Zheng He was his junior brother, and he has always been honest and honest, but he is not afraid of causing trouble.

Zhu Di had already stood up, and Hao Fenglou accompanied him to return to Beijing. When he passed through the inner east city, Zhu Di thought to himself, "What have you done recently? What are you doing? I have issued an order to make him a vassal, and I will set off these days, keep a good eye on it, and don't make any mistakes in the moment."

Hao Fenglou nodded and said, "Don't worry, Your Majesty."

Zhu Di was in a better mood and continued, "So you can't stay in the palace all day long. You have to go out and take a walk, otherwise I will have to get sick. Well, go do your own thing, and I will return to the palace."

Hao Fenglou and Zhu Di parted ways. This time, Hao Fenglou was in a much better mood. The King of Han had an excuse to stay and he was also planning to make a comeback. After this, the entire Jinyiwei was afraid that the number of people who had a good impression of him would increase greatly.

As for Zhu Di's visit to the camp, he also praised the Shenwu Guard. It seems that the level of the Shenwu Guard will be further improved.

Hao Fenglou returned to Qianhu House, and then someone came to visit him, but the one who came was not someone else, but the King of Han.

In fact, Hao Fenglou was not willing to have too much contact with the King of Han and always wanted to avoid suspicion, but he had come to the door and had no reason to turn it off.

Fortunately, Zhu Gaoxu came in casual clothes and had no show. Although he might be followed, at least he was quite low-key. Hao Fenglou welcomed him into the duty room, asked Zhou Fang to pour tea, and took the seat with Zhu Gaoxu. Zhu Gaoxu smiled and said, "The third brother is already in the vassal state. He has a good relationship with you. He often mentions you. If he doesn't leave, I want to come with him, but it's a pity. It's a pity..."

He said this with a different meaning. In fact, it was to bring the relationship between Hao Fenglou and him closer. Hao Fenglou and King Zhao got along, and Zhu Gaoxu had a harmonious relationship with his third brother. Just as friends of friends are also good friends.

Hao Fenglou smiled and said, "Actually, it's not a bad thing like King Zhao. Your Highness. Let's open the skylight and speak loudly. Your Highness will not enter the Three Treasures Hall for no reason, so he must have a purpose."

Hao Fenglou's words were a bit life-like. Zhu Gaoxu didn't care. People were like this. What he wanted most. The more distant Hao Fenglou was, the more he felt that Hao Fenglou was unfathomable, and he said, "Actually, I am here to thank Hao Qianhu this time. If it weren't for the solution you came up with, I'm afraid I would have to go to the vassal."

Hao Fenglou sighed and said, "But Your Highness should also understand that once you reach this point today, Your Highness can no longer turn back."

Zhu Gaoxu nodded. Of course, he knew what Hao Fenglou meant. He had already expressed his position and completely challenged the prince. From then on, the brothers will be incompatible. If they cannot replace the position of the prince, they will be liquidated sooner or later.

He said seriously: "I don't have to fight for the treasure, but I can't swallow it. What kind of ability does the prince have? Why is this king born and die in the Jingnan period, but he will kneel down to him in the future? His father is not the eldest son, and now he still rules the world. Although I am not as good as my father, I also have the ambitions of my father."

If this is what others say, it may make people's blood radiant, but this kind of words have no effect on Hao Fenglou. He just nodded calmly and said, "Knowing that there is a tiger in the mountain and going to the tiger mountain, your highness really makes the humble man admire him."

Zhu Gaoxu hesitated and said, "But now I am only staying in Beijing for the time being. My mother is already asking where I want to change the vassal. Although it is a temporary solution now, once the vassal is changed, I will still have to take the vassal sooner or later. Oh, my mother is urging me to hurry, and I am in a dilemma now."

Hao Fenglou smiled slightly and said, "In fact, it's easy. Your Highness just insists on enthroning the vassal of Peiping."

Zhu Gaoxu was stunned for a moment, Peking...

"I'm afraid it's inappropriate. My father has changed Peking to Shuntian Prefecture and established Beijing. Besides, it is a military territorial area. If you are a vassal, you will have 100,000 troops and horses, and the guards will have 150,000 people. Not to mention the crown prince, even the father will not agree."

Hao Fenglou smiled and said, "This is called asking for a lot of money to pay it back. Anyway, your highness said that he is used to Peking and wants to stay there and begging him. Even though Your Majesty and Empress Xu refused, they have to consider your highness's vassal state to appease you. In this way, how can you get things done in a few years? Your Highness can wait for an opportunity in the capital in recent years. As for whether the prince will give your Highness a chance, this is another matter. When Your Majesty is impatient, your Highness will bargain and say that he hopes to re-enact Shandong."

Zhu Gaoxu's eyes lit up and said, "Hao Qianhu said it well. He asked for a price all over the place and paid back the money. This is a good idea."

Zhu Gaoxu said a few more words to Hao Fenglou before saying goodbye. Before leaving, he looked at Hao Fenglou deeply, grabbed Hao Fenglou's hand and said, "Hao Qianhu, I am not talented and stupid..."

He wanted to take the opportunity to recruit him, but Hao Fenglou quickly pulled his hand back and said with a smile: "Your Highness is extremely smart, and he is used to being aloof. It is okay to give advice to your Highness. The rest are really powerless, so I hope your Highness will understand."

Zhu Gaoxu smiled bitterly and shook his head and said, "It's good that you don't have to see him off, I'm leaving."

After seeing off Zhu Gaoxu, Hao Fenglou breathed a sigh of relief and went back to the duty room to continue drinking tea.

For several consecutive days, Hao Fenglou has devoted himself to the Thousand Households, but during this period, he sent several drawings to Shenwuwei. One of them was about the bellows. At this time, it was the Ming Dynasty and the bellows had appeared. However, due to the simple structure, it was much worse than the bellows in modern times. Hao Fenglou lived in the countryside for several years in his previous life. At that time, the wind direction was popular in rural areas. He had some understanding of the structure and roughly drew a sketch to let the carpenters optimize and improve the pig iron based on this sketch. In some cases, it depends on the temperature. The normal fire is only eight or nine hundred degrees, and one thousand and two degrees is the limit. However, this temperature cannot dissolve the iron into iron, which makes the iron refined mixed with a large amount of impurities. If the temperature can be increased by improving the bellows and improving the iron furnace, Hao Fenglou believes that it can produce better pig iron.

So while Hao Fenglou delivered the bellows sketch, he also sent a blast furnace sketch he had figured out by himself. This sketch was actually based on the improvement of brick-burning kilns in later generations and blast furnaces. Hao Fenglou was not sure whether it was useful. Anyway, those stonemasons were idle and it was a pity that they didn't move bricks.

A few days later, when Hao Fenglou was doing nothing in a thousand households, an eunuch came on a horse, and someone had already come to announce: "The decree has arrived."

So Qianhu Office suddenly started a group of people, and everyone hurriedly moved the offerings and burned the incense. Hao Fenglou led the superiors and subordinates in the office to bow down in front of the case and said in unison: "I accept the order."

The eunuch's skin was well maintained, with fair skin, and said with a smile: "Hao Qianhu, you are polite and have official duties. We won't talk much about it. Please listen to the orders." Then, he looked serious, like a king, coughing twice according to the rules, and carefully holding out the imperial edict.

When the imperial edict was opened, the father-in-law's eyes fell on the imperial edict, and the majesty that had been shown was gone in a trace. Then the father-in-law instantly petrified and stayed in place, unable to move.

Especially those eyes were full of horror, as if they saw a ghost, and deep in their pupils, they contracted, contracted, and then contracted...

Everyone was waiting for the order, and their feet were numb. As a result, the eunuch was slow and he didn't hear a sound for a long time. So everyone raised their heads in confusion and looked at the eunuch in confusion.

Hao Fenglou was also impatient and couldn't help saying in his heart: "Brother, don't waste your expressions, you should recite it quickly."

"Cough cough..." The eunuch coughed again. This time it was not intentional to make a move, but the kind of cough with internal injuries, as if he wanted to cough out his heart and lungs.

In the end, the father-in-law gritted his teeth as if he was closed and letting others 'trash', and said with a complicated expression: "Nine nine six three, three four seven five, one two nine four, three three five seven, six nine four one..."

A long list of numbers is endless, hundreds of them.

As he was reciting, the father-in-law's tears fell down. He had been a eunuch for so long and had never seen such a strange thing. He doubted whether he had obtained the wrong imperial edict, or that his major had regressed, his eyes were blurred, and his mind was confused.

But all the numbers are in sight. Everyone was looking forward to reading them out. The arrow was on the string and it would not be possible to recite them. So he continued to pretend to be very majestic, and put on a sacred and inviolable tone of the emperor coming in person, and continued to recite: "Six five seven four, one one two nine, six eight nine four..."

Everyone was shocked. Some people were shaking their heads desperately, feeling that they were dreaming, some people couldn't listen, and they almost hit the ground with their heads. As the eunuchs were singing melodiously and rhythmically, three words appeared in Hao Fenglou's heart: "Grass-mud horse!"
