This kind of coke oven model made of mud, Zhu Changhao said very clearly, it is the other masters of the Ordnance Prison, the supervisor Sun Yuanhua, and the waiter Song Yingxing of the Ministry of Industry also understood at once, and many people also used pen and paper to draw it out, and recorded the functions of each layer.

Zhu Changhao saw that everyone didn't remember much, but he saw a few masters drawing the legends of the coke oven with a brush, looking at the outlined lines of different thicknesses, Zhu Changhao suddenly became green, the corners of his mouth twitched, and said, "In the future, all the legends of the Ordnance Supervision must be drawn with charcoal rulers, and the illustrations must be marked with numbers, and they must be standardized." ”

"Yes, we will obey the instructions of the prince", everyone saw Zhu Changhao speaking violently, and hurriedly clasped his fists and said.

"It's not too early for this king to see the sky, everyone, here today, the smelting furnace is completed, the coke furnace is completed, you will inform the king, finally, everyone must remember, our water flow is relatively turbulent, coking, steelmaking, we must think more about the use of water power, think about the technique, labor-saving, trouble, and, whether it is a smelting furnace or a coke oven, it is best to build an open top on it to prevent rain and snow."

"We will keep in mind the prince's instructions and send off the prince Jin'an."

The night breeze by the river is cool, and it is now the end of July, and there is no moon tonight. On the starry sky, a fiery red star hung high in the sky, although it was not so eye-catching, but it was also eye-catching, Zhu Changhao casually asked the housekeeper beside him, "What star is that crimson star?" ”

Liu Zheng glanced up, and just wanted to answer, but Uncle Wang next to him quickly said, "Lord Wang, that is Mars, also known as the Glowing Star, now it is July, when the Fu Qi is about to end, the Luminous Star is in the sky, and the ancients said that 'the fire in July is also'." ”

When Zhu Changhao heard this, he realized that in the 21st century, he thought that the 'July fire' was too hot in the summer, and the ground was going to be exposed to fire in July.

Zhu Changhao was asking the steward about the astrological question, and his nephew Emperor Chongzhen, who was far away in the capital, was watching an urgent report in the Taihe Palace.

"On July 23, the sea overflowed in Zhejiang, countless people and animals were drowned, and hurricanes and rains in Jiaxing caused countless drowning of coastal and suburban residents. Shaoxing is windy, the sea water goes straight into the county town, and the market can be boated. Shanyin, Huiji, Xiaoshan, Shangyu, and Yuyao were drowned, each in the tens of thousands."

This is the six-hundred-mile rush of Zhejiang Jinyiwei's fast horse urgent report, but Chongzhen is already frowning.

Since it was in the Taihe Palace, the Empress Zhou was also serving the emperor.

Empress Zhou sat on the brocade stool in front of the palace, gently cut a watermelon into small pieces, shaved off the melon seeds, inserted one of the pieces with a golden hairpin, gently handed it to Chongzhen, and said, "Your Majesty, you taste this, this is Miyun's watermelon this year, sandy, due to the lack of rain this year, the watermelon in Miyun Huangzhuang is sweeter than in previous years." ”

Chongzhen took the watermelon and was in a daze.

Seventeen-year-old young man, in such a high position, since he succeeded to the throne in October last year, in the first three months, because of copying Wei Zhongxian's family assets, he did become a dashing emperor for two days, but now, the imperial court is asking for money and grain when it comes to the localities.

Chongzhen took the watermelon and put it in his mouth, which was indeed not as good as in previous years.

Although there is a hint of Tianyi in his mouth, he is already bitter in his heart. Last year's locust plague and drought have caused the people's livelihood in the north to wither, and even Guangyuan Mansion, the country of abundance, has already caused a civil uprising. Since this year, the snowfall is on the low side, less than last year's 30%, the spring and summer drought, the summer grain production is reduced or even the harvest is a fact, but now, the situation in Liaodong is worse than that of my brother (Emperor of the Apocalypse).

Although the governors and political envoys of several places have made a break and said that there is a severe drought in some prefectures and counties, according to the current news of Jinyiwei, most of the five provinces of Gansu, Ningxia, Shaanxi, Shanxi, and Henan have been wiped out, and even Sichuan, the country of abundance, has been affected.

When it came to the beginning of autumn, there was no hope for autumn grain, and the provincial government that asked for relief did not know how much it would take. I don't know how much grain the fifth uncle can get from where in southern Guangdong, and can he get some silver taels for me?

When Queen Zhou saw her husband's thin face and some white fingers, she directly shed tears in her heartache, and said in a low voice: "Your Majesty, you also have to take care of the dragon body, although the Wanli country of the Ming Dynasty has to be governed, you are like this now, and the concubine is so worried." ”

Although there are many concubines in the harem, in Zhu Youzhen's heart, there are only the Zhou family, who is confident that the princess is the princess, and the other is the imperial sister-in-law Empress Zhang, but because she is her brother's woman, in order to avoid suspicion, she does not have much contact.

Chongzhen listened to Queen Zhou's words, raised his head and looked at his original match, and saw the worried look in his eyes, without any hypocrisy, and his heart warmed.

Thinking that in addition to being the emperor, he was also the husband of a woman, so he opened his mouth and said to the chief administrator Wang Chengen, "Wang Bandang, I will stay in the Baohe Hall tonight, and the brand will not be served." ”

"Yes, Your Majesty."

In the Baohe Palace, due to the sincere care of Queen Zhou, Chongzhen turned this strong care into the driving force of a fierce sprint tonight, and directly made Queen Zhou cloud seven times.

In the Baohe Palace, the room is full of spring.

In the palace, Zhu Changhao has returned, and he still has a sense of accomplishment in his heart for solving the coke oven today, and now that the steel has been trained, he just has to prepare this machine tool and the like, to be honest, he is still a little worried.

Who made themselves in the 21st century not "excavator technology which is stronger, Huaxia Zhili looking for Beixiang" skilled workers?

I haven't learned, but I have seen the appearance of some machine tools, because at the beginning, there was a manganese steel mill in my hometown, and the social research during the university holiday was the manganese steel mill, although it was to complete the tasks assigned by the school, but the production workshop, or I looked at it again, but I also had some impressions.

Especially cold-rolled steel, plate bending machines and the like have also been seen, and the working principle is also understood, but to draw a detailed structural drawing, Zhu Changhao is really a little difficult. In addition, if you want to produce silver coins in the future, you will need to use the water resources of the Han River to produce a forging press or a stamping machine.

The principle of the forging press is also clear to itself, that is, the punch is used to punch the silver plate, and then the pattern stamped on the silver plate by the shearing machine is completely cut into a round cake shape.

Now the question arises, how to produce the steel required for rolling machine tools, coiling machine tools, punches and shearing machines.

Zhu Changhao knows that these things are best tungsten steel, but how tungsten steel is produced, he only has a general impression, as if in the 21st century, in the physics of the third year of junior high school, he only remembers adding tungsten essence on the way to steelmaking, it seems to be 3 percent or 8 percent, he remembers it a little clearly.

But for manganese steel, he still knows that manganese steel seems to have to be added by about 20 percent, and the things produced will have high hardness, and there will be no magnetism at high temperatures.

Besides, now to look for tungsten ore, whether it is scheelite or wolframite, Zhu Changhao only knows the approximate origin, knows that tungsten ore is very heavy, very hard, and the origin also knows, it is in the Xiangjiang River Basin, but this thing is better to develop in the future.

Compared with the trouble of tungsten ore, manganese ore is very easy, in their own fiefdom, Hantai Mountain in Hanzhong, there is.

According to the iron smelting furnace of the government during the Chengzu period of Qingyang Yi in the past, there is such a saying, "Qingyang hot iron is bright red, Hantai stone is mixed with a little bit, and thousands of steel knives are smelted, and there is no need to grind for cutting iron and wood." ”

When Zhu Changhao heard this ballad at that time, he knew that there must be a trace element in the stone on this mountain, which can increase the hardness and density of steel.

Thinking of this, Zhu Changhao said to the subordinates outside the door, "Go and call Steward Zhang."

After saying to his subordinates, he felt a little hungry unguardedly, and looked inside the palace, and Qiao'er was on duty, and asked, "Where are the princess and Yu'er?" ”

"Lord Wang, Niangniang is in Miss Yu'er's courtyard, discussing business!"

"Oh, you go to the kitchen and take a look, get some pig's head meat, as well as refreshing side dishes and steamed buns, and come back, and this king will pad his stomach."

"Yes, lord, the slave will do it", Qiao'er finished speaking, made a blessing, and left.

Zhang Gongli came, and Zhu Changhao looked at the second housekeeper who was in charge of the palace rent and daily expenses, and seemed to be in the best mental state, after all, there were few positions in charge, and the way to live was relatively easy.

"Lord Wang, I don't know what to tell you to find an old slave?" Zhang Gongli clenched his fists and bowed and said.

"Lao Zhang, early tomorrow morning, you go to Hantai Mountain to bring two carts of stones, and you have to choose the kind of stones that those blacksmiths want, the stones are not too big, this king is useful."

"Yes, Lord Wang"

"In addition, now that the summer harvest is over, you will inspect the king's fiefdom on the fifteenth day of every month, look at the crops of the tenants, as well as the farmland and water conservancy, etc., and don't wait for the rent to be collected all day long, and the accounts of the king's expenses will be calculated."

"Yes, it's the old slave who is derelict in his duties, and the old slave will do it when he comes down."

"Well, that's good, you can go down."

Cold steamed buns, braised pork, two side dishes, one is a green chili pepper and cucumber salad, and another is an eggplant puree salad, looking at the green peppers to eat, Zhu Changhao realized that there are a lot of chili peppers introduced by the palace this year.

Zhu Changhao asked Qiao'er to pour himself a cup of herbal tea and began to eat. After being full, he put down the dishes and chopsticks, and went to the back garden of the palace to walk around and eat.

The next day, until the evening, two truckloads of manganese ore arrived in Hanzhong, and Zhu Changhao decided to try the smelting of manganese steel tomorrow.

Just when Zhu Changhao finished reading the manganese ore in the palace compound and wanted to ask the princess what she wanted to do, Liu Zheng came in with a letter, and after Zhu Changhao read it, his face immediately changed.
