Jia Jing turned over and dismounted. An official had already come forward to greet him. When he saw Jia Jing, he quickly bowed and said: "Zhengcheng, the supervisor of the Ordnance Bureau, met Marquis Ning in Yudao!"
Jia Jing looked at this person. It was Jian Zhengcheng Yudao, the top officer of the Ordnance Bureau. He seemed to be a very honest and honest middle-aged man. Compared with the serious Jia Zheng, he looked more pragmatic.
More like an old farmer than an official.
But he is indeed a fourth-rank official of Dayan! He is wearing a bright red Yunyanbuzi official robe and a short-winged black gauze hat, looking like a standard official of Dayan.
Jia Jing waved his hand and said: "Get up!" Cheng Yudao stood up quickly, but did not dare to look at Jia Jing. When he got the news that Jia Jing was coming to inspect the Ordnance Bureau, Cheng Yudao had the same idea as everyone else.
:
Don't you think this man is just trying to get away with nothing? Your Majesty won't let you, the Yulin Army, continue to play with firearms, so you will solve the problem directly from the source and directly contact the Ordnance Bureau?
So Cheng Yudao was actually worried, because he was just a technical director and a gatekeeper. He really had no right to decide who should give the weapons inside!
But people all over the capital are asking, what is this man's temper? He doesn't get what he wants. If this man is determined to transfer firearms from the Bureau of Ordnance today, then the only way he can succeed is to follow him
Fight!
Although Cheng Yudao himself knew that he could not defeat Jia Jing, what else could he do? All he could do was to rather die than surrender! Otherwise, if the weapons of the Ordnance Bureau were secretly mobilized, he would still not be able to escape the death penalty!
Therefore, Cheng Yudao's legs were actually trembling at this time, and he did not dare to look at Jia Jing! He was tremblingly thinking in his heart for a while how to refuse Jia Jing's unreasonable request without being humble or arrogant!
Jia Jing glanced at Cheng Yudao with some strange eyes, muttering secretly, and ignored him. He directly stated the purpose of his trip and said: "I'm disturbing Mr. Cheng this time despite his busy schedule, but I actually want to do some inspection."
Regarding the production situation of the Ordnance Bureau, please ask Sir Cheng to show me around."
"Please forgive me, Lord Marquis! This kind of request from me is really helpless, so why don't you ask Lord Marquis......"
Jia Jing looked at Cheng Yudao with a strange frown and said, "As the Left Governor of the Fifth Army Governor's Mansion, I am an unreasonable request to inspect the Ordnance Bureau? Isn't this justifiable, Master Cheng?"
Cheng Yudao nodded blankly, and then quickly shook his head. He really didn't expect why Jia Jing didn't follow the routine, but at this time he could only say quickly: "Okay! It's okay! Uh, Mr. Hou, this is
Please!”
Jia Jing nodded, then looked at Cheng Yudao's back suspiciously, and suddenly smiled evilly: "Oh... Mr. Cheng, do you think I am here to embarrass you?"
Cheng Yudao shuddered and quickly turned around and said with a smile: "No, no, no! How could the official think so? Lord Marquis misunderstood! Uh, Lord Marquis, please come here!" Jia Jing looked at it with a half-smile but not a smile.
He glanced at Cheng Yudao, then followed behind and began to observe.
In fact, it is still very rewarding. Many things make Jia Jing's eyes light up. In fact, many technologies are not weaker than modern people at all, and even far exceed modern people! Jia Jing is very amazed.
But while Jia Jing was observing with interest, Cheng Yudao, who was following Jia Jing, was covered in cold sweat. He felt that Jia Jing didn't bring it up now just because he was waiting for an opportunity, and he would soon snatch it away with a dark face.
These treasures of my own!
Therefore, Jia Jing's excited eyes at this time naturally turned into coveting eyes in Cheng Yudao's eyes, so Cheng Yudao followed with fear until he walked to the back and passed through the verandah of the main room. Jia Jing suddenly
He uttered a curse word: "Fuck me!"
Cheng Yudao was so frightened that he trembled and quickly looked at Jia Jing. He saw Jia Jing turned over and jumped out of the verandah in great excitement. Liu Ze quickly followed behind him. Cheng Yudao hurriedly climbed over and chased after Jia Jing.
Jia Jing quickly walked to the objects placed in the open space and glanced at the thing that looked like a tank in shock.
Iron chariots, moving wheels, and fire beasts?! I am invincible in the world!?
Jia Jing then turned around in shock and faced Cheng Yudao who was chasing him: "This, this, isn't this the legendary fire beast?" Jia Jing's voice trembled. If this thing is real, then
Jia Jing’s view of history is really about to collapse!
Unexpectedly, Cheng Yudao was confused for a while after hearing this, and then looked at Jia Jing pointing at the thing that looked like a tank in shock, and then smiled and said: "Oh, you said this! This is a side chariot! Throw it here.
It has been a long time since there were too many problems, so not many were produced. Counting this one, there are only two of them. Uh, which fire beast are you talking about?"
Jia Jing looked at Cheng Yudao and looked at him in confusion. If it was really a fire beast, wouldn't he have learned history in the past twenty years in vain? Fortunately, there are no ghosts in this world to that extent...
…
Jia Jing really doesn't know much about sidecars, and there aren't many historical materials left about these things in previous lives. Most of them are descriptions, but there are quite a few legends about them. Qi Jiguang played with them, and Sun Chengzong also played with them.
And it was said that it was very well received, so Jia Jing still looked around this sidecar with great interest.
Cheng Yudao saw that Jia Jing seemed to be very interested in this sidecar, so he took the initiative to introduce it: "This car is improved according to ancient methods. Lord Marquis, please take a look. The shaft of this car is one foot and three feet long.
The horizontal shaft is nine feet wide and seven feet five inches high. The carriage is divided into left and right compartments by thin boards."
Cheng Yudao pointed to the front and said: "There are two detachable antlers on the front of the car. If you encounter an enemy, you can put them down by yourself." Jia Jing nodded, then Cheng Yudao stepped forward and opened the door and said: "This car can accommodate two sharpshooters.
There are one cannon and two gunners, one strong bow, two card players, two long swords, and ten general-purpose soldiers. When there is no battle, they can take turns pushing and pulling. When encountering the enemy, they can close the carriage and fire cannons from a distance.
, when the enemy is encircling you, you can also release your soldiers to fight!"
Jia Jing's face was solemn, and Cheng Yudao came out and said with a smile: "There is a carbine in this car to fill the gap. The top and bottom of the frame are surrounded by cotton tents to avoid arrows. The car is equipped with two Franco guns.
There are thunder cannons and six fast guns at the bottom. Each horse-repelling gun has 12 long spears on the top. There are thunder cannons and six fast guns at the bottom. Each vehicle can have up to twenty-five pawns!"
Jia Jing frowned slightly and said, "So powerful?" Jia Jing had fought in a war, so he naturally knew what a powerful firepower it was! Cheng Yudao smiled proudly and nodded.
Jia Jing blinked in confusion and said, "How come there are only two such powerful chariots built?" Cheng Yudao's smile solidified, and he said with a sly smile: "Master Marquis, I don't know that this kind of chariot weighs as much as
Six hundred kilograms, the vehicle is too heavy, requires too many men and horses, is not easy to transport, is not easy to fight for a long time, uh, and is not suitable for danger, moves slowly, takes a long time to enter the battlefield, and is not easy to attack, so, uh, haha...
"
Jia Jing looked at Cheng Yudao expressionlessly and said: "So he is a waste?" Cheng Yudao seemed to have been shot in the heart, but he still nodded with a wry smile. Jia Jing rubbed his chin and said: "
In fact, the main problem is still slow action, right?"
Cheng Yudao nodded and sighed: "Xiaoguan and others can't figure out how to increase its speed or how to make it adapt to various battlefield terrain conditions. Therefore, we can only abandon it here."
Nonsense, it would be strange if you could think of it! Before there was a complete industrial foundation, who could have imagined such a thing as a steam engine?
Jia Jing was also helpless. He didn't understand mechanical matters, so he could only look at the sidecar reluctantly, then turned around and left. Cheng Yudao had no choice but to follow, and Jia Jing turned around and took a look.
Sidecar, I silently thought in my heart, sooner or later, I want it to become an energy-producing monster that roars on the battlefield!
Jia Jing said to Cheng Yudao: "Sir Cheng, in fact, the main purpose of my visit today is to visit the smelting plant of the Ordnance Bureau." Cheng Yudao was stunned for a moment, and then said: "You mean, you want to see it
Iron kiln?"
Jia Jing nodded, and Cheng Yudao smiled bitterly and said: "The iron kilns of the Ordnance Bureau are all far away from the outskirts of Beijing. You..." Jia Jing said without hesitation: "Yanagisawa! Be ready."
horse!"
After saying that, he turned around and left without looking back. Cheng Yudao had no choice but to follow him. In fact, it was not too far away. Ironmaking requires a lot of water, so the Ironmaking Factory of the Ordnance Bureau was
Beside the river not far from the outskirts of Beijing.
As soon as Jia Jing got off the horse, she saw several gray-faced people squatting there. They didn't care about the mess on their hands. They grabbed the steamed buns and gnawed them. Jia Jing took Cheng Yudao forward. Those people saw Cheng Yudao.
He quickly stood up and said hello.
Cheng Yudao waved his hand and said: "It's okay, it's okay! You eat what you have!" Then he said to Jia Jing behind him: "Old Songtou, come here, this is,,,,,,"
Several workers were so frightened when they saw the python robe that Jia Jing was wearing that they immediately knelt on the ground and shouted, "Have you ever seen a prince before?" Jia Jing had no choice but to help her personally: "I am not a prince! I don't want you to kneel either.
Get up quickly!"
Only then did everyone get up, and the old man who Jia Jing helped up quickly hid aside and said: "He's dirty! It's hard to bump into a noble person!"
Jia Jing looked at the steamed buns in their hands and the cabbage soup in the thick porcelain bowls, and felt a little uncomfortable.
As a child of workers and peasants in his previous life, it is inevitable that he has a natural affinity with workers and peasants. Jia Jing asked: "Old man, do you eat this for lunch?"
Old Songtou smiled when he heard this and said: "It's easy to deal with it! I've been working so hard recently that I really can't take care of eating! Only then, only then,,,,,, haha, made the noble man laugh!"
Cheng Yudao on the side also stepped forward and said: "Master Hou, Old Songtou is the best old craftsman in the nearby iron kiln run by our government! If you have any questions, just tell them!"
Jia Jing nodded, and Lao Songtou also said quickly: "My lord, what can I do for you?" Jia Jing smiled and said: "Well, I also had a whim, Yanagisawa took out the things."
Liuze nodded in agreement, turned around and took out a firearm from under his horse. Jia Jing took out the firearm and handed it to Lao Songtou and said: "Song Gong, show me this and see where it comes from."
question?"
Old Songtou took over the firearm with a confused look on his face. He was about to say that I don't know how to do this, but as soon as he took over, he really felt something was wrong!
Old Song banged the firearm's rod with his head, his blackened gray eyebrows tightly knitted together and said: "His! My dear, this seems to be an iron problem!"
Jia Jing immediately said: "Do you probably know what the reason is?" Old Song turned his head over and over to check, and finally nodded firmly and said: "It is definitely because of the iron quality! Your iron is brittle! It is not wear-resistant! This
After the gunpowder explodes inside it several times, it will become thinner and the chamber will explode if used again!"
Yanagisawa also suddenly said: "Most of our soldiers know this when they use firearms. After using them a few times, they have to explode! Sometimes they are hot to the touch!"
Jia Jing nodded and said: "Do you have a way to solve this problem?" Old Songtou suddenly realized: "You mean, you want to make this thing more durable!"
Jia Jing nodded repeatedly, and Old Songtou smacked his lips and said: "For this, even pig iron and wrought iron will not work. In my opinion, we can only use steel!"
Jia Jing nodded and said: "Can you always cast a steel pipe like this and show it to us?" Old Songtou immediately nodded and said: "My lord, please wait a moment, I will start the furnace right now."
But Jia Jing waved her hands and said: "No need, let's go with you!" Cheng Yudao quickly dissuaded him and said: "Master Hou, stay!" Jia Jing turned to look at him, Cheng Yudao smiled bitterly and said: "Master Hou doesn't know something.
, There are many dangers in this kiln, and the Marquis has no experience, so why don’t you go in?"
Jia Jing shook her head and said: "Who said I have no experience? You just lead the way!" I was taken to a steel factory when I was four or five years old, right? Modern steel plants are not as dangerous as yours?
Seeing that Cheng Yudao couldn't persuade him, he could only bite the bullet and follow. Everyone walked and chatted along the way, and Jia Jing also took the opportunity to learn about the iron smelting industry in this world.
Jia Jing asked: "Approximately how many people are there in Song Gong's kiln factory?" Old Songtou calculated in his mind for a while and said: "Oh! That's a lot! There are 410 civilian men and 425 military men.
There are 286 military craftsmen and 410 shift craftsmen! There must be more than 2,590 people in total!"
Liu Ze was shocked and said: "So many?" Old Songtou laughed and said: "This is not a lot! There are only so many people, and we have to work hard to pay the fees this year!"
Jia Jing nodded and observed the ancient smelting scenes around her. She was extremely surprised, but she asked Old Songtou on her face: "How many kilograms can you make in a day?"
Old Songtou chuckled and said: "That's not certain, but our factory uses a Dajian furnace. One furnace can only produce 81,600 kilograms. It is not a problem to burn three or four furnaces a day!"
One furnace is 81,600 kilograms! If you burn three or four furnaces a day, doesn’t that mean you can produce 323,000 kilograms a day? This is just a steel plant! A steel plant like this, whether private or government-owned,
, there are 456 in the entire Dayan!
Of course it cannot be compared like this. After all, this is the largest government-run iron factory near the capital. Other iron factories may not have such output and may not be able to afford the Dajian Furnace, but this steel output is definitely impressive!
Jia Jing looked serious, and Lao Songtou also took out the cooled steel pipe, handed it to Jia Jing and said: "Your Excellency, please take a look."
Jia Jing looked at the steel pipe in her hand. This was completely different from the steel she had seen in her previous life. Although it was indeed very strong in terms of hardness, its color and strength were far behind modern steel.
.
Jia Jing knew the key to this at a glance. This kind of steel is not doped with manganese! There are two indicators for steel to become hard and shiny. The first is that it needs to be in the converter during the refining process.
time, add manganese to it!
The second is to reduce the content of carbon, sulfur and other impurities in steel! Only in this way can the steel be made harder and shiny!
The steel in their hands is actually much softer than modern steel. The ancients already knew how to "fried steel" by blowing air or adding concentrate powder during the converter, or by using pig iron and wrought iron.
Doping is used to reduce the carbon content and transform pig iron into steel.
But the carbon content in such steel is still too high! This will make the steel soft and brittle! Jia Jing couldn't help but sigh.
Seeing Jia Jing's disappointed look, Cheng Yudao said without any surprise: "It's not that we haven't thought about replacing the barrel with steel, but the result is that the explosion rate is higher than that of pig iron! We had no choice but to use steel to save costs.
Wrought iron is here to make it.”
Jia Jing was silent. He had the impression that an anchor from Zheng He's ship when he sailed to the West was unearthed in Quanzhou, Fujian. This anchor was nothing unusual, but after investigation, historians came to a surprising result:
The carbon content in this anchor actually reaches an astonishing 0.01%! And the surface frosting process is even and delicate, not inferior to modern technology at all!
In other words, the level of this anchor has completely reached the standard of modern steel used to produce cars! People in the Yongle period could do it, but there is no reason why we can't do it!
Without modern large-scale equipment, how did Ming craftsmen reduce the carbon content in steel to such a low level?
Jia Jing didn't have time to think about this. The first people to mine manganese ore were Americans in the 19th century! Where could he find manganese at this time? He was not a geologist. Although he knew that China's manganese ore production was very high, how did he know?
Where can I find manganese ore in China?
However, Jia Jing vaguely remembers that there is probably some in Liaoning, but at this time, how long will it take to send people to Liaodong to find it? They don’t even know what manganese ore looks like!
Jia Jing sighed. Cheng Yudao probably knew the purpose of Jia Jing's trip, so he could only comfort Jia Jing to be more open-minded. Just leave this kind of matter to them. As the governor, Jia Jing doesn't have to worry about these small things.
Jia Jing followed Cheng Yudao in silence and left the iron factory, but halfway, Jia Jing stopped again. Cheng Yudao closed his eloquent mouth and looked at Jia Jing blankly.
Jia Jing looked at Cheng Yudao and frowned slightly: "I can definitely make it! It can be done without manganese ore!" Then she pulled the reins and headed towards the iron factory!
