Jia Jing turned over and dismounted, and an official had already stepped forward, and after seeing Jia Jing, he hurriedly bowed and said, "The Inspector of the Ordnance Bureau is Cheng Yudao and has seen Ning Hou!" ”

Jia Jing looked at this person, it was the highest commander of the Ordnance Bureau, Jian Zhengcheng Yudao, who seemed to be a very honest and honest middle-aged man, compared to the fake and serious Jia Zhenglai, he looked a little more pragmatic, more like an old farmer than an official.

But he is indeed the four-grade member of Dayan! He was wearing a red-bottomed cloud goose mending official robe, and a short-winged black gauze hat, which was the standard appearance of a Dayan official.

Jia Jing waved his hand and said, "Get up!" Cheng Yudao hurriedly got up, but he didn't dare to look at Jia Jing, when he got the news that Jia Jing was coming to inspect the Ordnance Bureau, Cheng Yudao and everyone else had the same idea:

This lord doesn't want to empty gloves white wolf, Your Majesty won't let you continue to play with firearms, you will directly solve the problem from the source, and directly reach out to the Ordnance Bureau?

So Cheng Yudao is actually worried in his heart, because he is a technical director and watches the door, who should give these ordnance inside, he really has no reason to make the decision!

But the Manshen Capital inquired, what kind of temper does this lord have? What does he want and what he doesn't get? If this master is determined to transfer firearms from the Ordnance Bureau today, then he can only fight with him when he becomes a Taoist!

Although Cheng Yudao himself knew that he couldn't beat Jia Jing, what else could he do? All he can do is rather die than give in! Otherwise, the ordnance of the Ordnance Bureau was transferred without permission, and he still couldn't escape a capital crime!

Therefore, at this time, Cheng Yudao was actually trembling with both legs, and he didn't dare to look at Jia Jing squarely! trembling in his heart, he pondered for a while how to refuse Jia Jing's unreasonable request without being humble or arrogant!

Jia Jing glanced at Cheng Yudao's sneaky muttering with some strange eyes, and didn't care, and directly said the purpose of this trip: "This time I disturbed Lord Cheng in my busy schedule, but I actually wanted to inspect the production situation of the Ordnance Bureau, and asked Lord Cheng to lead Ben Hou to take a look around." ”

"Master Hou, please forgive me! This kind of request is really helpless, and I ask Master Hou to ............... Ga? ”

Jia Jing looked at Cheng Yudao strangely and frowned slightly: "As the governor of the Zuo Capital of the Five Armies, it is also an unreasonable request to inspect the Ordnance Bureau?" Cheng Daren, this can't be said, right? ”

Cheng Yudao nodded stunnedly, and then hurriedly shook his head, I really didn't expect why Jia Jing didn't play cards according to the routine, but at this time, he could only hurriedly say: "Yes!" OK! Uh, Master Hou, please! ”

Jia Jing nodded, then looked at Cheng Yudao's back suspiciously, and suddenly smiled evilly: "Oh............... Does Lord Cheng think that Benhou is here to embarrass you? ”

Cheng Yudao shuddered, and hurriedly turned his head and said with a smile: "No, no, no!" How could Xia Guan think that? Hou Ye misunderstood! Uh, Master Hou, please! Jia Jing glanced at Cheng Yudao with a smile, and then followed behind and began to observe.

In fact, it is still very rewarding, many things make Jia Jing's eyes shine, in fact, many technologies are not weaker than modern people at all, and even far more than modern people! Jia Jing was very breathtaking.

It's just that when Jia Jing was observing with great interest, Cheng Yudao, who was following Jia Jing, was covered in cold sweat, he felt that now Jia Jing didn't bring it up just because he was waiting for an opportunity, and soon he would snatch these treasures of his own with a black face!

So at this time, Jia Jing's excited eyes naturally became covetous eyes in Cheng Yudao's eyes, so Cheng Yudao followed all the way in fear, until he walked to the back and passed through the verandah of the hall, Jia Jing suddenly burst into a foul mouth: "! ”

Cheng Yudao was so frightened that he hurriedly looked at Jia Jing, only to see Jia Jing turn over and jump out of the verandah very excitedly, Liu Ze behind him hurriedly followed, and Cheng Yudao hurriedly climbed over to chase Jia Jing.

Jia Jing walked quickly to the object that was placed in the clearing, and glanced at the thing that looked like a tank in shock.

Iron Wheel Assault Fire Beast?! I'm invincible!?

Jia Jing then turned his head in shock and said to Cheng Yudao, who was chasing after him: "This, this, this can't be the legendary fire beast?" Jia Jing's voice trembled, if this thing is real, then Jia Jing's view of history will really collapse!

Who knew that Cheng Yudao was confused for a while when he heard this, and then looked at Jia Jing in shock and pointed to the thing that looked like a tank, and then smiled: "Oh, you said this!" This is a partial-compartment chariot! It's been here for a long time, because there are too many problems, so not too much has been produced, and there are only two of them counting this, uh, what are you talking about? ”

Jia Jing looked at Cheng Yudao and looked at himself suspiciously, relieved, if it was really a fire beast, then his twenty-odd years of history were not in vain? Fortunately, there are no ghosts in this world...............

The partial van, Jia Jing really doesn't know much, and there are not many historical materials left of these things in his previous life, most of them are descriptions, but there are really a lot of legends about it, Qi Jiguang has played, Sun Chengzong has also played, and it is said that it is also very praised, so Jia Jing is still looking around this partial van with great interest.

Cheng Yudao saw that Jia Jing seemed to be very interested in this partial car, so he took the initiative to introduce: "This car is improved according to the ancient method, Hou Ye, please see, the wheels of this car are one foot and three feet long, the front and rear horizontal wheels are nine feet wide, and the height is seven feet and five inches, and the carriage is divided into left and right compartments with thin plates." ”

Cheng Yudao pointed to the front and said: "The front of the car is hooked to take off the antlers, and you can put it down by yourself when you encounter the enemy." Jia Jing nodded, and then Cheng Yudao stepped forward to open the car door and said: "This car can accommodate two guns, two gunners with the same cannon, one strong bow, two players, two long knives, and ten general armor soldiers. ”

Jia Jing's face was solemn, Cheng Yudao came out again and said with a smile: "This car is equipped with a horse rejection gun, fill the gap, the frame is surrounded by cotton wool cloth tents, which can prevent the loss of stones, the car carries two Franc machines, the lower thunder cannon, six fast guns, each with 12 tree spears on each horse rejecting gun, and six fast guns under the lower one, and each car can use up to twenty-five pawns!" ”

Jia Jing frowned slightly and said, "So powerful? "Jia Jing has fought a war, so he naturally knows what a powerful firepower this is! Cheng Yudao smiled and nodded complacently.

Jia Jing blinked his eyes suspiciously and said, "How did you build two such powerful chariots?" Cheng Yudao's smile froze, and he said with a wry smile: "Master Hou doesn't know, this kind of chariot weighs six hundred catties, the cart style is too heavy, there are too many people and horses needed, it is not easy to transport, it is not easy to fight for a long time, uh, and it is not suitable for danger, it is slow to move, it takes a long time to put into the battlefield, and it is not easy to attack, so, uh, hehe..............."

Jia Jing looked at Cheng Yudao expressionlessly: "So he's just a waste?" Cheng Yudao seemed to have been shot from the heart, but he still nodded with a wry smile, Jia Jingmo rubbed his chin and said, "Actually, the main problem is still slow action, right?" ”

Cheng Yudao nodded and sighed: "The lower officials and the others can't figure out how to make it increase its speed, and how to make it adapt to various battlefield terrain conditions, so they can only abandon it here first." ”

Nonsense, it's weird if you can think of it! Who could have imagined such a thing as a steam engine without a complete industrial base?

Jia Jing was also very helpless, he didn't understand mechanical things, so he could only reluctantly glance at the partial van, and then turned around and left, Cheng Yudao had no choice but to follow, Jia Jing turned his head and glanced at the partial van, thinking silently in his heart, sooner or later, one day, to make it an energy-producing monster on the battlefield!

Jia Jing said to Cheng Yu: "Lord Cheng, in fact, the main purpose of Ben Hou's visit today is to visit the smelter of the Ordnance Bureau. Cheng Yudao was stunned for a moment, and then said: "You mean, you want to see the iron kiln?" ”

Jia Jing nodded, and Cheng Yudao smiled bitterly: "The iron kilns of the Ordnance Bureau are far away on the outskirts of Beijing, you .................." Jia Jing said without hesitation: "Liu Ze!" Hurry up the horses! ”

Saying that, he turned his head and left, Cheng Yudao had no choice but to follow, in fact, it was not too far, ironmaking requires a lot of water, so the ironworks of the Ordnance Bureau are next to the river not far from the suburbs of Beijing.

As soon as Jia Jing got off the horse, he saw several grizzled people squatting there, and he didn't care about the mess on his hands, grabbing the steamed buns for a while, Jia Jing took Cheng Yudao forward, and those people saw Cheng Yudao and quickly stood up to say hello.

Cheng Yudao waved his hand and said, "It's okay, it's okay!" You eat yours! Then he said to Jia Jing behind him: "Old Song Tou, come here, this is ,,,,,,"

Several workers saw the python robe on Jia Jing's body, and hurriedly knelt on the ground and shouted that he had seen the prince or something, Jia Jing had no choice but to step forward and help him in person: "This Hou is not the prince!" Don't you kneel, get up quickly! ”

Only then did everyone get up, and the old man who Jia Jing had helped up with his own hands also quickly hid to the side and said, "It's dirty!" It's not good to bump into nobles! ”

Laughing with fear, Jia Jing looked at the steamed buns in their hands and the cabbage soup in the coarse porcelain bowl, and felt a little uncomfortable.

As a child of workers and peasants in his previous life, he was inevitably born with a sense of closeness to workers and peasants, Jia Jing asked: "Old man, do you eat this at noon?" ”

Old Song Tou smiled when he heard this: "It's okay to deal with it!" Recently, I've been in a hurry, and I really can't take care of eating! This is this, this is ,,,,,, hehe, let the nobles laugh! ”

Cheng Yudao on the side also stepped forward and said: "Master Hou, Old Song Tou is the best old craftsman in the iron kiln undertaken by our government nearby!" Just let them know if you have any questions! ”

Jia Jing nodded, and Old Song Tou also hurriedly said, "Nobleman, do you have something to do?" Jia Jing smiled and said, "Well, Ben Hou was also on a whim, and Liu Ze took out the things." ”

Liu Ze nodded yes, turned around and took out a firearm from under the horse, Jia Jing took out the firearm and handed it to the old Song Tou and said, "Song Gong, you show me this, can you see what went wrong?" ”

Old Song Tou took the firearm with a confused face, and just wanted to say that I wouldn't know this, but as soon as he took it, he really felt that something was wrong!

Old Song Tou tapped on the rod of the firearm, and a bunch of blackened white eyebrows wrinkled tightly together: "Hiss! Noble man, this seems to be an iron problem! ”

Jia Jing immediately said, "Do you probably know what the reason is?" Old Song Tou looked at it over and over, and finally nodded firmly: "It's definitely because of the iron quality!" You iron brittle! Not wear-resistant! This gunpowder exploded in it a few times, and he had to become thinner, and if he used it again, he would have to explode! ”

Yanagisawa also said suddenly: "Most of our soldiers know this when they use firearms, and if they don't use it a few times, they will have to blow up!" Sometimes it's hot! ”

Jia Jing nodded and said, "Do you have a way to solve this problem?" Old Song Tou suddenly realized: "You mean, you want to make this thing more durable!" ”

Jia Jing nodded again and again, and the old Song head smacked his lips and said: "This, you can't use pig iron and wrought iron, according to the little old man, you can only use steel!" ”

Jia Jing nodded and said, "Can you cast a steel pipe like this and show us?" Old Song Tou immediately nodded and said, "Your noble, please wait a moment, little old man will start the furnace." ”

Jia Jing waved his hand and said, "No need, let's go too!" Cheng Yudao hurriedly dissuaded: "Master Hou stays!" Jia Jing turned his head to look at him, and Cheng Yudao smiled bitterly: "Master Hou doesn't know, there are many dangers in this kiln, Master Hou has no experience, so don't go in?" ”

Jia Jing shook his head and said, "Who said that Ben Hou has no experience? All you have to do is lead the way! "Lao Tzu was taken to the steel mill to play at the age of four or five, okay? Isn't a modern steel mill more dangerous than yours?

Cheng Yu Dao couldn't persuade him, so he could only keep up, 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, "How many people are there in the kiln factory of Song Gong?" Old Song Tou calculated in his heart for a while and said, "Yo! That's a lot! There are 410 men, 425 soldiers, 286 warmen, and 410 shift craftsmen! There must be more than 2,590 of them! ”

Yanagisawa was shocked: "So many? Old Song Tou laughed and said, "That's not much!" There are so many people, and we still have to rush to work with the amount of money to be paid this year! ”

Jia Jing nodded, observing the ancient smelting scene around him, he was amazed in his heart, but said to Lao Song Tou on his face: "How many catties can you refine in a day?" ”

Old Song Tou smiled and said: "This is not possible, but our factory uses Dajian furnace, how can a furnace get 81,600 catties, and it is not a problem to burn three or four furnaces a day!" ”

One furnace is eighty-one thousand six hundred pounds! Burn three or four furnaces a day, isn't that 3230,000 catties a day? It's just a steel mill! Iron and steel factories like this, whether they are private or governmental, there are 456 in the entire Dayan!

Of course, it can't be compared like this, after all, this is the largest government-run iron factory near the capital, and other iron factories may not have such output, and may not be able to afford Dajian furnace, but this steel output is definitely enough!

Jia Jing's expression was serious, and Old Song Tou also took out the cooled steel pipe, handed it to Jia Jing and said, "Noble, please take a look." ”

Jia Jing looked at the steel pipe in his hand, which was completely different from the steel he had seen in his previous life, although it was indeed very strong in terms of hardness, but whether it was color or strength, there was a gap compared to modern steel.

Jia Jing knew the key to this at a glance, there was no manganese doped in this kind of steel! If steel wants to become hard and shiny, there are two indicators, the first is that it needs to be added to it during the refining process, when it is converterd!

The second is to reduce the content of carbon and sulfur and other impurities in steel! In this way, the steel can be harder and shinier!

The ancients already knew how to "fry steel" by blasting or adding concentrate powder during the converter, or by doping pig iron and wrought iron 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.

Cheng Yudao saw Jia Jing's disappointed appearance and said without any surprise: "It's not that we haven't thought about steel replacing the barrel, but the result is that the explosion rate is higher than that of pig iron!" As a last resort, we had to use wrought iron to save costs. ”

Jia Jing was silent, he had the impression that Quanzhou, Fujian Province had unearthed an anchor on Zheng He's ship when he went to the Western Ocean, this anchor was nothing unusual, but historians came to an amazing result after investigation:

The carbon content in this anchor is an astonishing 0.01 percent! Moreover, the surface frosting process is uniform and delicate, which is not inferior to modern technology!

In other words, the level of this anchor is completely up to the standard of modern steel for the production of cars! People in the Yongle period can do it, there is no reason why we can't do it!

In the absence of modern large-scale equipment, how did the craftsmen of Daming reduce the carbon content of steel to such a low level?

Jia Jing didn't have time to ponder this, the first to mine manganese ore was the Americans in the nineteenth century! Where did he go to find manganese at this time? He is not a geology student, although he knows that China's manganese ore production is very high, but how does he know where there is manganese ore in China?

However, Jia Jing probably vaguely remembered that Liaoning probably existed, but at this time, when would he send someone 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 persuade Jia Jing to look away, just leave this kind of thing to them, Jia Jing, as the governor of the capital, don't have to worry about these little things.

Jia Jing followed Cheng Yudao out of the iron factory in silence, but halfway through, Jia Jing stopped again, and Cheng Yudao closed his mouth and looked at Jia Jing in a daze.

Jia Jing looked at Cheng Yudao and frowned slightly: "I will definitely be able to refine it!" You can do without manganese ore! Then he pulled the reins and headed in the direction of the ironworks!
