Chapter 493: Tossing and Turning, Causing Trouble!

"Master, I'm checking the hue, brightness, and concentration of the flame!"

The environment was too noisy, so Jin Mi answered loudly.

Everyone couldn't help but frown slightly when they heard this.

Only Zhu Di's eyes lit up, but he didn't speak.

Zhu Yuanzhang was even more curious. He raised his finger and pointed at the three-swing converter and asked with a smile: "How do we feel that this flame has not changed at all? Is there any mystery in it?"

Jin Mi smiled shyly and scratched his head, "Master, this is my own experiment, pig iron slurry, wrought iron slurry, mixed steelmaking in the laboratory. It has not been verified in large-scale industrial applications, and I don't know if it is correct." ”

"Tell me! Tell me, Master. Master wants to hear what you discovered." Zhu Yuanzhang encouraged loudly with a smile.

Jin Mi looked at Zhu Di and Xu Miaoyun.

Zhu Di and his wife smiled and nodded in encouragement.

Jin Mi silently took a deep breath and introduced: "Master, I found that through the hue, brightness, and concentration of the flame, first of all, you can judge the temperature in the furnace, and secondly, you can also judge the quality of the steel produced. "

…

"The color of the flame is white and bright; the concentration of the flame is thick and opaque; and the height of the flame is not high. These characteristics all indicate high temperature."

"The color of the flame is dark blue; the concentration of the flame is thin and transparent; and the height of the flame is very high. These characteristics all indicate that the temperature is low."

…

Jin Miyue said, the look on his young and immature face getting brighter and brighter.

From time to time, he pointed to the converter not far away and made gestures in order to tell Zhu Yuanzhang more clearly.

Zhu Yuanzhang looked at Jin Mi's energetic and young face, and while smiling, he couldn't help but sigh in his heart: This little guy really likes to do these studies.

If you don't like it, you won't have this look on your face when talking about these things.

This little guy's talents are based on Jin Yiwei's tracking records in previous years.

Although not as good as the best ones like Dongxu and Yuanji.

But there is no problem at all in taking the imperial examination and becoming an official.

If you were a young scholar in the Ming Dynasty, if you had this talent, you would have studied hard and sharpened your head to become an official.

I would never do this kind of dirty, tiring and painful research like Jin Mi.

This is the gap between Zhongyuan and Laosi.

Comes from the gap in thinking!

"Master, look, the flames are starting to flutter and become less sticky. Moreover, the flames explode into several small flowers in mid-air, with big sparks and many branches."

Zhu Yuanzhang came back to his senses, squinted his eyes, and looked at the converter in the direction of Jin Mi's finger.

Everyone also looked at it carefully.

Sure enough, it was exactly what Wang Jinmi said.

Hu Weiyong, Lu Ben... everyone pricked up their ears, trying hard to hear what Jin Mi would say next.

"According to my small-scale experiments in the laboratory, the molten steel produced at this time forms a steel billet that has the disadvantages of high hardness, strength, and poor cooling plasticity. The steel produced at this time can be used to make crowbars, hammers, and drill bits. , reamers and other tools.”

"Although the carbon content of this kind of steel is lower than that of pig iron, it is still very high. I call this kind of steel rich carbon steel."

…

"The swing of the flame has shrunk slightly; the spark branches remain 3 to 4, and the branches are long and powerful; most of the ejecta is sparks."

"I classify the steel produced at this time as medium carbon steel. The steel produced in the laboratory has better preheating processing and cutting performance, and has strong endurance and tension. If this kind of steel is used To build a house, the steel refined from a small amount of small steel furnaces used in building houses in Yanjing is better than that. This kind of steel is made into steel bars to build a house. I think it is enough to ensure that even a seven or eight-story house is built. Solid, but this is my speculation and has not been verified.”

…

"When the flame swings violently, mainly from above, the bright white flame leaves the top; the spark disappears, and occasionally becomes weak, with only 2 to 3 branches; most of the ejected objects are sparks and stars (sparks that spray very quickly), Start spraying slag particles.”

"The steel billet that comes out of the furnace at this time is mild steel. I also call it low carbon steel. This kind of steel has low strength, low hardness and softness. It has very good plasticity and toughness, especially cold plasticity. It can be pulled directly without preheating. Steel wire, if this kind of steel is used to stamp the steel helmets used in the military, it will be easier to stamp and form. As long as it is stamped and formed, and then tempered and carburized, the hardness and strength of the helmet surface can be improved. "

"This kind of steel is very suitable for making paper clips, rivets, bolts, shafts, and bicycle chains. It can effectively simplify the process difficulty in manufacturing parts. If the hardness and strength need to be improved, as long as the parts are made and tempered Just carburize it.”

…

"Master, that's all. These are all my own guesses. I don't know if they are correct or not."

At the end of the sentence, Jin Mi became shy again, scratching his head with a smile.

Ha ha……

‘This is an honest kid. ’

Zhu Yuanzhang laughed heartily, patted Jin Mi on the shoulder, and encouraged: "Master doesn't understand this, but Master knows that when doing this kind of research, you are not afraid of making mistakes. Even if you are wrong a thousand or ten thousand times, as long as you are right once, you will be successful." You succeeded, work hard!”

Jin Mi smiled and saw Zhu Yuanzhang staring at the converter intently, so he stood beside Zhu Di without disturbing him.

Zhu Di looked at it with a smile and said with appreciation: "Master, your summary feels very reasonable. Since the correctness has been verified through small-scale verification in the laboratory, the possibility of application in large-scale industry is also very high."

He never expected that this little guy would actually come up with an experience summary of judging carbon content through flames.

I am afraid that in the laboratory of the Research Department, there is a lot of sweat, using small crucible furnaces, one furnace after another.

Before there were more advanced technical means.

Even the industrialization period in history.

In steelmaking, the quality of steel is also judged by observing the flame.

Jin Mi happily pointed at the converter and whispered: "Master, if my conclusion is correct, and this new type of raw and wrought iron converter steelmaking can be successful, in the future, as long as we train some experienced people who can 'watch the fire' Masters can control the quality of steel more stably, and there is no need to mix and re-smelt the steel in several batches to achieve a balanced steel quality."

Zhu Di nodded.

Not only can the steel quality be balanced.

‘Fire watching’ is also a prerequisite for large-scale industrial steelmaking.

To be honest, the small 100-pound steel furnace used by the First Steel Plant is not called industrial steelmaking.

It's just a handicraft steelmaking method that's slightly more advanced than wrought iron.

"You have concluded that high carbon steel, medium carbon steel, and low carbon steel, have you identified the carbon content of the three steels?"

Jin Mi scratched his head, "Master, the student really wants to identify, but the variables involved are beyond the control of the student. For example, if the steel produced in the small crucible converter in the laboratory is poured out and waited for condensation and weighing, the remaining steel in the crucible furnace will Part, has a great influence on weighing and determining the carbon content.”

…

Zhu Di listened carefully. The difficulties Jin Mi encountered were uncontrollable variables.

Reminder: "Why do you need to pour it out and weigh it? You can weigh it together with the crucible furnace. As long as you weigh every clean crucible furnace in the control group before refining, the total weight after refining is cooled Just subtract the weight of the crucible furnace.”

"In addition, the most important thing for this experiment is to choose pig iron and wrought iron produced in the same batch. Even if the carbon content of pig iron and wrought iron produced in the same batch is slightly different, the difference should not be big. More It can ensure balance.”

…

"Under our current conditions, if we want to measure more accurate carbon content, we need to increase the number of experiments. Suppose we select ten batches of pig iron and wrought iron. Each batch of pig iron and wrought iron must be tested for at least ten batches. For the secondary carbon content measurement and identification test, first find the average carbon content of ten tests in each batch, add the average values ​​of the ten batches, and then calculate the average. The carbon content data obtained in this way will be more accurate. "

Wang Jinmi's eyes lit up and he said happily: "Master, I understand! Master taught us when we were young!"

By expanding the amount of data and finding the average, this method was learned when the master gave them math lessons when they were children.

I haven't used it in so many years, and I actually forgot about it.

Zhu Di smiled and pointed at the converter, "Look at the flame, it looks like the low carbon steel flame you mentioned. Is it time for this furnace of molten steel to be released?"

Jin Mi couldn't wait to run to the laboratory for experiments right now, but was brought back from his thoughts.

Quickly get closer, take a closer look, even pull off the goggles, squint and take a closer look, then quickly back away and blow the whistle.

Di——

At the same time as the sharp whistle sounded, a flag message was played and shouted: "Close the No. 8 gas valve, operate the No. 9 gas valve alone, and push the converter to dump molten steel!"

Trumpeter on the high platform.

Suddenly he opened the whistle valve next to him.

Di——

A long and sharp whistle sounded.

White gas spurted out from the whistle horn, and the trumpeter turned to face the steam engine area and stockpile area behind, and quickly played the semaphore.

squeak!

With a sharp and piercing sound, the converter was pushed out by the cylinder from the high-temperature burning fire.

Several workers, wearing thick linen special work clothes, iron masks and goggles, were pouring water on their bodies when several co-workers poured a large basin of water on them.

Several people cooperated with each other, holding a long iron rod with an iron hook, rushed forward, and hooked the huge iron hook reserved on the edge of the converter.

"one two three!"

The trumpet sounded.

The mouth of the pot-bellied converter tilts outward.

As several workers dragged their iron bars and ran backwards to evacuate, hot molten steel poured down.

It flows along the diversion groove reserved below to the billet cooling area next to it.

Jin Mi watched the converter pouring the molten steel. He stood up like a tumbler and introduced to Zhu Di in a low voice: "Master, in the design, we tried repeatedly and wanted to use the power provided by the steam cylinder to pour the iron slurry instead of The dangers posed by manual dumping are huge.”

"However, there are many technical difficulties that cannot be overcome for the time being. Although some of the mechanical structures used in them have been designed and passed experiments, they have the disadvantages of being too complex, too difficult to maintain, and having poor durability. Moreover, if these mechanisms are added, bracket, it will also cause the durability of the three-width swing mechanism to be reduced...

After hearing this, Zhu Di smiled and comforted: "Don't worry, you can build this converter, which is already very impressive."

Of course he knew that the more complex the mechanism, the worse its durability.

Especially in the early stages of this industry.

When making industrial equipment, you must take the stupid, bold, and bold route.

During this period, if we go for refinement, it will stifle the development of industrialization.

Only with the continuous development of industrialization and various disciplines such as materials science and design making great progress can we pursue precision and sophistication.

"For workers engaged in this process, we can provide strict training and set up other safeguards in the operating environment. For example, can we draw a green line in front of the converter to indicate the safe area, draw a yellow line closer to indicate a certain dangerous area, and draw a red line in the most dangerous place? Through these eye-catching reminders, workers engaged in this process can be reminded at all times."

"In addition, some workers engaged in dangerous processes should be given higher treatment and disability protection."

"In addition, for workers in this process, they are prohibited from working while tired. Workers in other processes work eight hours a shift. Can these dangerous processes only take three or four hours?"

"In short, the technology is not up to the task. While slowly thinking about improving the technology, we can completely overcome the various dangers and inconveniences caused by technical defects from other aspects. How to implement these I said specifically depends on your continuous exploration and summary in the next large-scale industrial test, and summarize a set of safe production processes."

The laboratory test was successful.

The completion of industrial project construction does not mean that large-scale industrial production can be carried out immediately.

It is also necessary to carry out industrial production practice for three or four months.

Inspecting equipment, exploring processes, training workers...

He doesn't need to talk about these.

In the industrial construction over the years, this set of processes has been explored and summarized in practice.

Zhu Di watched the steel billet cooling down. In the converter, another furnace of smelting began, and the workers were busy using large iron tongs to move the cooled and formed steel billets away to make room for the next furnace to cool down.

Zhu Di turned his head and saw that Zhu Yuanzhang's face was flushed with heat. He was worried that it was too hot and would be bad for Zhu Yuanzhang's health, so he smiled and suggested: "Father, let's go and see the cooled and formed steel billets?"

Zhu Yuanzhang came back to his senses and looked at the piles of steel billets piled up by the workers, "Okay!"

Everyone followed Zhu Di to the steel billet pile area.

The factory director handed a manual drill to Zhu Di, and at the same time brought a piece of pig iron and wrought iron.

After seeing it, Zhu Di put the drill bit against the steel billet and shook the handle.

A moment later, Zhu Di drilled a shallow hole in each of the three billets.

He stood up and handed the manual drill to Zhu Yuanzhang.

After trying it, Zhu Yuanzhang nodded and said, "The hardness of this steel billet is indeed softer than pig iron and harder than wrought iron. It is still uncertain whether it is the low-carbon steel that Jin Mi mentioned, but it is definitely steel."

It can be used to cast cannons, muskets, boilers, carriages, bicycles, and Century Bridges without any problems.

Turning his head, he asked Jin Mi: "Little guy, tell me, how many kilograms does this furnace produce? How many tons can it produce every day?"

Jin Mi smiled and replied: "Master, such a furnace is one thousand kilograms, and it takes three to four hours to smelt pig iron and wrought iron..."

Jin Mi pointed to two blast furnaces, "These two blast furnaces can smelt ten tons of pig iron and ten tons of wrought iron, a total of twenty tons. If you use a converter to make steel, if you want to make this kind of low-carbon steel, one furnace takes half an hour, that is to say, to turn twenty tons of pig iron slurry and wrought iron slurry into steel, each furnace of 1,000 kilograms of molten steel requires forty furnaces."

"One furnace takes half an hour, and forty furnaces take twenty hours."

"This furnace, according to our design, can just do it for twenty-four hours, people rest, but the furnace does not rest."

"It can produce twenty tons of steel a day!"

"That is to say, now that you have this new converter, the amount of steel you make in one day exceeds the total amount of steel you made in a year before?" Lan Yu exclaimed.

He did not forget that when observing the 100-jin small steel furnace, Zhu Laosi said that Yan Fan now produces more than ten tons of steel a year.

Hu Weiyong and Lu Ben looked at each other.

Twenty tons a day.

Three hundred and sixty-five days a year.

Just such a steelmaking furnace.

Yan Fan can produce 7,300 tons of steel!

This is 7,300 tons of steel!

How many can be made for making guns and cannons!

Jin Mi is not only thinking about what Lu Ben and Hu Weiyong think.

He knew that Lan Yu had no hostility towards his master, and smiled and nodded: "In theory, this is the case. This steelmaking furnace is just an experimental furnace. Our Yan Fan's blast furnace technology for smelting pig iron and wrought iron can already achieve a 100-ton blast furnace."

This is not his bragging.

Although such a large blast furnace has not been used in iron smelting.

But this 100-ton blast furnace has been used in cement firing.

"As long as the technology is successfully verified, we will not build this kind of energy-consuming and costly ten-ton small furnace. Even if we don't build a hundred-ton blast furnace, we will at least build a fifty-ton blast furnace directly."

"One pig iron blast furnace and one wrought iron blast furnace are a total of one hundred tons. At the same time, although the thousand-jin converter in the middle, we can't make a bigger one with the technology we have now..."

It's not that we can't make a bigger one.

The main thing is that it's difficult to control the heating and smelting of a larger furnace and the full mixing of the raw and sparse iron slurry solution.

"However, we have thought of a way to set up a string of dozens of thousand-jin converters in the middle."

Adding a converter is very simple.

It's nothing more than ensuring that the steam power is sufficient, and copying it according to the current converter mechanism.

...

Is it that simple?

Lan Yu and others looked at Jin Mi talking freely, and it seemed very easy.

They couldn't help but be silent.

These seemed very easy for Yan Fan, for this little guy who was obsessed with researching technology. As he said, it was just copying.

But if it was the Ming Dynasty.

They all listened in a daze, let alone construction.

…

Everyone came out of the steel mill.

Zhu Yuanzhang took Jin Mi off and said a lot.

Then get on the carriage.

When the carriage started, Zhu Yuanzhang couldn't help but waved to Jin Mi who was standing at the door through the window.

Zhu Di smiled and said, "I can see that my father is very happy."

snort!

"A dog's mouth can't spit out ivory!" Zhu Yuanzhang snorted, withdrew his gaze and looked at Zhu Di, "Such a blast furnace can produce 7,000 tons of steel in a year. If you want to build a bigger one, wouldn't it be possible to produce 7,000 tons of steel in a year? The output will reach hundreds of thousands of tons? "

Zhu Di nodded, "There are only a few months left this year, and there is a high probability that this steel furnace will be verified. However, next year we will definitely build the fifty-ton or one-hundred-ton blast furnace that Jin Mi mentioned."

"Don't be overjoyed with success." Zhu Yuanzhang warned earnestly: "How much steel consumption do you have now? Suddenly the output increased several times. Don't let it happen that when you build the Century Bridge, there will suddenly be no sales. The large scale of the steel plant means that, There are many workers who are responsible for this job. If there is no sales, it will be a problem for workers to eat, and they will definitely be resentful of you and your regime. "

Zhu Di nodded seriously and explained with a smile: "I have remembered my father's teachings. However, with the increase in steel production, I am not worried about sales at all. With the emergence of new steel-making methods, large-scale industrial smelting has Starting with steel, costs will plummet."

"A thousand small steel furnaces each weighing 100 kilograms each, and seven to eight hundred people, can produce more than a dozen tons of steel a year. It consumes a lot of energy, and the labor costs are even more terrifying."

"This new steel furnace with an annual output of 7,000 tons only requires more than 300 people. One day's output is equivalent to that of a year. I estimate that the cost of steel is at most one percent of that of a small steel furnace. , as the price of steel decreases, the prices of machinery such as bicycles, new horse-drawn carriages, and animal-drawn harvesters must be cut by at least half so that more people can afford them. The increase in sales of such products can completely consume hundreds of thousands of tons of steel. "

At the end of the Qing Dynasty, why was there no such indigenous steelmaking method developed in a small 100-pound steel furnace?

It is because the price of foreign steel is cheaper than that of domestic steelmaking.

Why is it that the steel produced by blast furnaces like Daye Steel Plant, which uses backward foreign technology, has poor sales and is on the verge of bankruptcy?

You know, it stands to reason that the labor costs of the Qing Dynasty at that time were much lower than those of foreigners.

The era he lived in.

It relies on low labor costs and high energy-consuming technical equipment that is one or several generations behind to produce industrial goods that are cheaper than foreigners.

In fact, the reason is also very simple.

With the loss of tariff sovereignty and railway sovereignty, foreign steel was controlled by foreigners through control of tariffs, dumping at low prices, and the power to build railways.

You know, the construction of railways at that time consumed the most steel.

Daye Steel Plant has no market.

Even if its labor costs are low, it will not be able to develop.

And, of course, there's the bureaucracy.

Under such circumstances, the failure of the Westernization Movement was inevitable.

Zhu Di gathered his thoughts and continued: "In the future, Hai'er will also provide this kind of cheap steel to the green bicycle factory. With the cheaper labor costs in Ming Dynasty, Hai'er estimates that the bicycle cost of the green factory can be reduced to Within two silver coins, many people may be able to buy a bicycle or a human-powered tricycle after saving for a year."

"When the rail train is really developed in the future, even hundreds of thousands of tons of steel a year may not be enough. I estimate that under our Yan Fan rule alone, Japan, Penglai, and Luzon will build a continuous railway. The north-south railway, coupled with the steel consumption of other industries, probably requires two to three million tons of steel every year.”

"If the imperial court can cooperate with me, the Yan Fan, to build the Grand Cross Railway in our Central Plains, I can assist the imperial court in building the steelmaking technology and train a group of steel workers and railway and bridge construction workers in the process of building the Grand Cross Railway."

Of course he would not follow the example of the foreign devils in treating the Qing Dynasty and the Ming Dynasty.

To assist in the construction of technology, he will also assist in the construction of truly advanced technology.

As for him, is it profitable?

Of course there is.

The steelmaking plant built with assistance will definitely not be able to meet the needs of railway construction.

Most of the steel materials had to be provided by Yan Fan.

As well as steam locomotive locomotives, carriages, etc.

After the completion of the two grand cross railways, Yan Fan made a lot of profits from them, which spurred the explosive development of Yan Fan's industry.

The Ming Dynasty also mastered steelmaking and railway construction.

In the future, we will build three vertical and three horizontal railways, which will still be 100,000 miles or 200,000 miles.

Even Ming Dynasty could rely on the technology he assisted in construction and build it on its own.

Cultivate and develop the steel industry of Ming Dynasty.

This is a partnership that offers the best of both worlds.

Although Yan Fan suffered a slight loss in the construction technology, he didn't care.

Only with sufficient competition can Yan Fan be forced to carry out industrial upgrading.

snort!

Zhu Yuanzhang smiled and said: "It can be seen that the rail train is not there yet. You are already thinking about the Grand Cross Railway plan..."

Zhu Di smiled and scratched his head.

Zhu Yuanzhang smiled and glared. Even if he didn't know much about industry, he knew very well that in this plan, although it would be beneficial to the fourth Yan Fan.

But the court took advantage.

That is the fourth child.

If the current leader of the Yan clan is not named Zhu, he is not Laosi.

Will Ming be given so many tangible and intangible benefits in this way?

Won't!

He knows very well the relationship between countries.

"Dad makes you a promise. As long as Dad is still alive, if you make a rail train, Dad will sign a cooperation plan for the Great Cross Railway with your Yan Fan as the founding emperor of the Ming Dynasty!"

The rules he set.

Even if he is gone.

Biaoer should still execute it, right?

He didn't know about this, but he was very sure.

Zhu Di smiled happily and said, "Then the child must really work hard to make sure that the emperor can see the train!"

...

"Yan Fan is too powerful!"

In the carriage at the back, Wang Yu looked out the window at the large iron bridge that was moving backwards, and at the industrial area with billowing smoke to the south of the large iron bridge, and couldn't help sighing.

"Those steel giants, Ling Gu... Ling Gu..."

He saw the Yan Fan industrial area, and those steel giants were cold all over.

In the converter, the molten slurry poured in an instant.

The fiery red heat wave that came to his face seemed to swallow and melt him by the raging flames spit out by the beast of Yan Fan.

"My dear, if I forbid our Goryeo scholars to come to Yanfan to study, will it annoy Yanfan?"

Li Shi's face suddenly changed, "King..."

"I will not forbid our Goryeo upper-class children to come to Yanfan." Wang Yu raised his hand to interrupt Li Shi, "But I can't let those reformists see this scene in Yanfan, otherwise, those damn reformists will only become more fearless!"

Li Shi was silent.

Can it really be banned?

He didn't think so.

Merchants from Yanfan frequently traveled to Goryeo.

The more it was banned, the more curious those various reformist groups would be about Yanfan, and there would inevitably be many young scholars from the lower classes who would sneak into Yanfan on Yanfan's ships.

It is reported that many people in the Ming Dynasty sneaked into Yanfan!

…

"Whether to surrender to the Ming Dynasty is still uncertain, but we must not offend the Yan Clan. In the future, even if we make friends with the Ming Dynasty and get along with both sides, our shogun must not make friends with the Ming Dynasty on the premise of offending the Yan Clan."

Hino Yoshiko looked at Zhu Di's carriage and said solemnly to her brother Hino Zikang and her eldest son.

I thought that the industry of the Yan Clan was similar to what they saw in the Jinling Industrial Zone of the Ming Dynasty.

At that time, she thought about it.

The industry is the same.

The Ming Dynasty is larger.

It seems that when the time is right, they can get rid of the control of the Yan Clan by making friends with the Ming Dynasty.

She didn't believe that Yan Wang Zhu Di was so kind to let them develop in the subcontinent.

In the description of Yan Wang Zhu Di, the subcontinent is clearly a piece of land that is richer and more fertile than Japan.

Such a piece of land is closer to Yan Clan.

Why didn't Yan Clan occupy it?

So, she believed that Yan Wang must have other intentions to migrate them.

But people have to bow their heads under the eaves.

Perhaps, before the King of Yan achieves his goal.

They can gain a foothold in the subcontinent, grow stronger, and not fear the Yan Fan?

In the future, it depends on who is more skilled.

...

But since she came to the Yan Fan, the more she understands, the more desperate she becomes.

What the Yan Fan shows is really too powerful!

The ferocity of its powerful industry seems to swallow everything!

Of course, she will not sit and wait for death.

Perhaps, the strength of the Ming Dynasty will increase in the future?

The Ming Dynasty does not need to be too strong.

With its huge size, as long as the industrial scale has one-tenth of the Yan Fan, it may be able to destroy the Yan Fan.

It is said that the relationship between the Ming Prince and the King of Yan Zhu Di is becoming increasingly tense.

In the future, the two sides may not be without the possibility of fighting.

She has also met the Ming Prince Zhu Biao.

Submission to this person is definitely better than the King of Yan Zhu Di.

When facing the Ming Prince Zhu Biao, she did not have the feeling that her neck was firmly restrained by someone, as if she would suffocate at any time.

But every time I face Yan Wang Zhu Di, I will have this feeling.

"Yeah."

Hino Azuyasu hummed lightly and reminded: "Don't hesitate, go to see Yan Wang today, we must start to migrate people before other princes, the sooner we go to the subcontinent, the greater the benefit to us, in addition, we must rent and purchase some armed merchant ships from Yan Wang, we must control part of the transportation capacity of the migrated people, and we can't be completely controlled by Yan Fan."

...

That night.

Many people can't sleep.

Zhu Di's study.

"Your Majesty, I object!" Yu Jing stood up excitedly, "Our navy warships have only been built for three or four years, they are all top-notch warships, how can we sell them to Japanese pirates! What if they learn our technology?"

Zhu Di smiled and looked at Yu Jing, who only took in and never left, like a Pixiu.

It seems that no matter which era the navy is in.

They all have the character of Pixiu.

"We definitely can't just sell them the warships. We sell armed merchant ships, not warships. So, except for the deck guns, all other cabin guns must be removed. These warships can be sold at a price 40% to 50% higher than the purchase price."

"After gradually selling these warships, we will replace them with warships that are fully steam-powered. At the same time, with the technological progress of our steel production and steel rolling production lines, I am also thinking about asking the shipyard to build a few iron-clad warships. This kind of iron-clad warship is more suitable for your long-distance exploration."

To be honest.

He didn't expect that technology would advance so fast.

If he had thought of it earlier, he would have been able to make a steam-powered ship so quickly.

Three years ago, he would never have started the hybrid shipbuilding plan.

But it's not a loss.

The price of this batch of warships can completely replace a steam-powered fleet.

Yu Jing smiled and scratched his head, saying, "If that's the case, I support the sale of warships that have been dismantled and converted into armed merchant ships. It's just right to let these Japanese pirates go to the vicinity of the Chen Dynasty to make trouble for Chen Zuyi. The Japanese princes' seizure of the coast of the subcontinent can also limit the expansion of the Chen Dynasty in this direction. In the future, when the Chen Dynasty is destroyed, the Japanese princes can also be asked to send troops!"

Even if the prince accepts the Chen Dynasty's tribute.

It is not convenient for them to attack the Chen Dynasty.

They can also drive the Japanese pirates to attack, and then they will 'attack' the Japanese pirates and annex the Chen Dynasty!

Has the prince already thought of the future friction between him and the prince and has begun to lay out in advance?

Seeking monthly tickets, recommendation tickets, follow-up subscriptions, and full subscriptions.
