After Changsun rushed away, Li Xiaogong glanced at Yang Fan with a complicated expression. Finally, Youyou sighed and said, "You have the character of a fighting cock, right away. Now Changsun Chong may even hate me."
Without the other people around, Yang Fan became more casual. He walked to Li Xiaogong and sat down alone. He chuckled and said disapprovingly: "The prince's military strategy is so great that all the barbaric foreigners are staying away. How can he be afraid of a pretty boy who relies on his father's generation?"
Hearing this, Li Xiaogong didn't know whether to laugh or cry. He pointed at Yang Fan and cursed with a smile: "I just want to be an old man who is greedy for pleasure, but you use me as a shield. I have a grudge against you or something?"
"Besides, that kid is just as bad as his father. I don't want to cause trouble for myself. You should be careful during this time."
Yang Fan couldn't help but be stunned when he heard Li Xiaogong's words.
It stands to reason that even when facing Changsun Wuji, the Hejian County Prince would not be conceited.
Why are you so afraid of Changsun Chong now? Is there something hidden?
Seeing Yang Fan's face full of confusion, Li Xiaogong shook his head slightly.
Yang Fan is a kid with first-class abilities and learning, but his sensitivity to officialdom is a bit low!
The officialdom and the battlefield are two completely different places, and it is not possible to convince others with fists.
What's more, the Firearms Supervision, as a department that His Majesty Li Er attaches so much to, now has his eldest grandson rush in. Of course, he is helpless.
On the one hand, the Changsun family controls more than half of the iron ore transactions in Datang.
Without the support of the Changsun family, it would be extremely difficult to refine steel.
If there is not enough iron ore, how can we make muskets?
On the other hand, letting Changsun Chong enter the Firearms Prison was actually the result of a compromise between the emperor, the prince, the aristocratic family... all parties.
In addition to Changsun Chong, there are other children from aristocratic families in the Firearms Prison!
To put it bluntly, Changsun Chong represents the forces on the prince's side.
Although the emperor had great power, he had to consider the prince's feelings and compromise with the family.
It is also terrifying for these aristocratic families to unite, although it is impossible to overthrow His Majesty Li Er's rule.
But that's for sure. If these guys are looking for trouble, the emperor can't kill them all, right?
This is why His Majesty Li Er asked him, a prince who had nothing to do at home, to serve as the supervisor of the Firearms Supervisor.
The purpose is obvious!
The emperor wanted to use his seniority to suppress the members of the aristocratic family who joined the firearms prison.
Of course, it is also to prevent Yang Fan, a disobedient guy from messing around and ruining things!
In order to successfully create the musket and thunder, His Majesty Li Er put a lot of effort into it.
Of course he doesn't allow his efforts to fall short!
But now that Yang Fan came, he was at odds with the eldest grandson, which really gave Li Xiaogong a headache.
Yang Fan is really a troublemaker, and he doesn't bow his head at all.
No wonder His Majesty Li Er told him to pay more attention to this guy before coming here.
Thinking of this, Li Xiaogong could only say helplessly: "I am actually afraid of Changsun Chong. Is Wannian County Duke surprised?"
"But have you ever thought about who he represents?"
Yang Fan frowned slightly and asked in confusion: "Who else can that boy represent besides the eldest grandson's family?"
"His Royal Highness the Crown Prince..."
"oh!"
Only then did Yang Fan suddenly realize.
Unexpectedly, even the newly established Firearms Supervision Bureau became a battlefield.
Not only were the emperor and the aristocratic families fighting, but the various princes were also fighting for power and profit.
Seeing Yang Fan's clear expression, Li Xiaogong added: "I'm here. Rather than being the supervisor of the Firearms Supervisor, I'm here just to show my name."
"My king has only one purpose, which is to ensure that the imperial court can successfully produce firearms to blast the sky."
Yang Fan smiled bitterly. He originally thought it was a very innocent thing, but he didn't know it was also a fight.
Sure enough, wherever there are people there are fights!
But he still asked with some reluctance: "If they mess with me, can they just be a coward? I can't stand being cowardly."
Li Xiaogong said disapprovingly: "As long as we can produce muskets and thunder, I will not bother to deal with your disputes!"
Yang Fan looked dumbfounded!
This county prince obviously wants to be the hands-off shopkeeper!
However, it is also his style!
Since being crowned king, this guy has been degrading himself. He has numerous beauties and mansions at home, just to avoid getting involved in the imperial dispute.
If His Majesty Li Er hadn't invited him to come out this time, the prince might still be enjoying himself in the gentle countryside!
Thinking of this, Yang Fan couldn't help but smile bitterly and said: "It seems that my days as a firearms supervisor will not be easy in the future."
Li Xiaogong chuckled: "I can't control what you want to do, and I don't want to. I just want to complete the task assigned by His Majesty as soon as possible."
Yang Fan touched his nose and felt confused: "Then the prince can't just ignore everything, can he? Otherwise, why would you, the supervisor, be here?"
Li Xiaogong rolled his eyes and looked like a scoundrel: "I'm here to enjoy myself. What do you think His Majesty wants me to do? Make guns? That's what you should do!"
Yang Fan was really speechless!
This county prince is indeed very messy.
No wonder the original history records that this guy actually did the ridiculous act of sharing a mistress with his son.
Yang Fan had no choice but to ask: "You, the prison guard, are no longer in charge, so wouldn't the firearms prison become the private domain of Chang Sun Chong, the young prison guard?"
"That kid obviously doesn't deal with me. How can I do my job?"
Since Li Xiaogong wanted to be a shoo-in, Yang Fan certainly wanted him to express his stance.
Otherwise, that guy Chang Sun Chong would use chicken feathers as his arrows, which would be very annoying.
Li Xiaogong said displeasedly: "Why do you think so much at such a young age? A good man should face difficulties, work hard, make great achievements, and become a debt. Why do he shrink back when encountering difficulties?"
Yang Fan directly pretended to be cowardly: "It's not me who came to the Firearms Prison, it was His Majesty who forced me to come! My ambition is to have a group of beautiful concubines, eat together and wait to die!"
Li Xiaogong really couldn't listen anymore!
However, this kid's ambition is surprisingly consistent with his.
Li Xiaogong has been in the officialdom for many years. Of course, Yang Fan wanted him to delegate power, so he laughed and scolded: "You boy is born in the year of the monkey. In this way, there are two positions for the Young Prisoner of Firearms. Changsun Chong takes one and gives up the other." How are you?"
"As for my ugly words, the production of muskets and thunderbolts is the top priority. Don't get carried away."
"As for what you want to do in the firearms prison, that's your business, as long as you don't kill anyone in front of me."
Yang Fan laughed when he heard Li Xiaogong's words.
Sure enough, a child who cries gets milk.
Although Yang Fan didn't like the position of Young Prisoner of Firearms at all.
But Su Dingfang is still a non-staff member now!
Since then, he has fulfilled his promise and temporarily found a job for Su Dingfang.
It seems that Li Xiaogong really wants to be a hands-off shopkeeper.
However, Yang Fan liked it very much.
So he said with a smile: "Your Excellency, I have brought a talented person here this time. How about giving him the position of young prisoner?"
Li Xiaogong thought for a moment and then agreed: "Sure, please present his official diploma so that I can report it to His Majesty!"
"Thank you for the recommendation, Your Majesty. This person is Su Dingfang, who was suspended by His Majesty some time ago..." Yang Fan bowed and thanked him.
Li Xiaogong was stunned for a moment, then laughed loudly and said: "I have always heard that Wannian County Duke has an upright temperament, but after this deal, I know that I am as cunning as a fox. You actually said that I recommended you. You are too cunning! However, I The king admits it!"
Seeing Li Xiaogong react so quickly and so generously, Yang Fan couldn't help but sigh.
No one who can leave his name in history is a simple person.
Although Li Xiaogong usually looks like a fool who is greedy for pleasure, in fact, he is like a bright mirror in his heart.
If you really think of him as a fool, then you will really become a fool!
This time it seemed that Yang Fan took advantage, but in fact Yang Fan owed him a huge favor.
However, Yang Fan decided to accept this favor from him!
After talking about the main business, the two chatted about some men's topics.
Since their interests and hobbies were similar, the two had a feeling that they had known each other for a long time.
In the end, it was Yang Fan who said goodbye, and Li Xiaogong gave up.
After leaving the check-in room, Yang Fan was a little worried.
I know from the chat just now!
This time the firearms supervision department has actually started to supervise the production of muskets and thunderbolts.
Because the quality of steelmaking is not up to standard, the finished pistol can easily explode.
This makes Yang Fan a little strange!
Although the steelmaking during the Tang Dynasty was far inferior to that of later generations, the steel produced was not so fragile.
Is there something wrong inside?
With such doubts, he walked towards the steelmaking workshop under the leadership of Jin Wang Li Zhi.
He wanted to see where the problem was.
When they arrived at the steelmaking workshop, Chang Sun Chong was also there.
He was not surprised by Yang Fan's arrival, but looked forward to it.
Li Zhi on the side quickly reminded Yang Fan in a low voice: "Brother-in-law, you have to be careful that Chang Sun Chong is a stumbling block for us!"
Yang Fan glanced at His Highness the King of Jin in surprise.
Could it be that this kid is starting to have a desire to compete for the throne, otherwise there is no need to target Changsun Chong!
If you look at it, Changsun Chong represents the forces of the prince's lineage.
Perhaps understanding Yang Fan's meaning, Li Zhi quickly explained: "The steel produced now is not up to standard because the Changsun family is unwilling to contribute the most advanced steel-making technology. Obviously Changsun Chong wants to see our jokes... "
Yang Fan was a little surprised when he heard Li Zhi's words.
But when I thought about it again, I felt it was natural.
This time, I served as the technical person in charge of the firearms supervision of the production of pistols and Hongtian Lei.
If qualified steel cannot be tempered, then making a barrel with extremely high tolerance may be empty talk.
Changsun Chong obviously wanted to show off his power and make him laugh.
In Changsun Chong's view, unless Yang Fan could contribute his own steel-making skills, it would be possible to create a qualified gun barrel.
However, top-notch steel-making technology is the lifeblood of a family, and there is no way Yang Fan can use it for no reason, even if the other party is His Majesty Li Er.
Besides, His Majesty Li Er is still his biological uncle, and their eldest grandson family is still unwilling to come up with the most advanced steel-making technology!
However, Yang Fan didn't want to care about Sun Chong's thoughts.
Seeing a pile of scrap materials piled up in a corner of the workshop, I walked over and picked them up to take a look.
These scraps have all been made into gun barrels, but unfortunately they are either bent or exploded.
Obviously, these products are not up to standard.
Yang Fan picked up a gun barrel, looked at it carefully for a moment, took out the knife he carried with him, and chopped it down.
The discarded gun barrel broke with a sudden sound, but Yang Fan's knife was unscathed.
Yang Fan frowned and thought to himself.
Not only did the hardness and toughness of this gun barrel fall far short of the standard, it far exceeded Yang Fan's psychological expectations.
I originally thought that with just a few adjustments, I could produce muskets and thunderbolts. Apparently Yang Fan was a little too naive!
So Yang Fan decided to find out what was going on. He turned to Li Zhi and said, "Take me to the steel furnace to have a look."
When he came to the steel-making furnace, Yang Fan himself was dumbfounded!
He knew that the steel-making technology in the Tang Dynasty was very backward, but he never expected that the imperial steel-making furnace would be so crude.
It is no different than the steel-making furnace originally built by Wang Xuance in Junyangfang.
In Yang Fan's opinion, these shaft furnaces are not for making steel at all, but for making iron.
Because there is charcoal burning under the stove!
These steel-making furnaces are almost four meters high and have a bottom diameter of about two meters. They are thicker in the middle and slightly narrower at both ends. The outer skin is covered with mud.
There is a charging port at the top and a blast port at the bottom, which allows the relative movement of the charge falling and the hot gas rising.
The high temperature generated by combustion passes through the furnace body and transfers heat to the charge, which is considered a heating process.
There is no blower in these furnaces, and only some iron remains in the furnace!
Although Yang Fan didn't know what the iron-making furnaces looked like in later generations, that didn't stop him from understanding the truth after reading it once.
Compared with the steel-making furnace you redeemed from the system, this thing is too crude.
Yang Fan asked Li Zhi beside him: "You just use this to make steel?"
Hearing Yang Fan's question, Li Zhi looked surprised, but he quickly said: "Brother-in-law, this is not a steel-making furnace, but an iron-making furnace. If you want to get fine steel, it is impossible to make it directly from the iron-making furnace. "
"This kind of furnace produces fine iron. Only by repeatedly tempering and quenching these today can you get the steel you just saw."
"But I don't know where there is a problem. What we got just now cannot meet the needs of the gun barrel."
"Either it's hard enough but too brittle, or it's malleable enough but too soft. We've tried many times but can't find the reason!"
Yang Fan rubbed his forehead and said nothing, he was too depressed.
Xin said, this broken furnace is so crude, it will not be easy to boil molten iron.
If charcoal is used for heating, how high can the furnace temperature be?
How much temperature is needed to make iron?
Yang Fan touched his chin and thought for a while, it was probably more than a thousand degrees, right?
When he first established the steelmaking plant in Junyangfang, he went out of his way to check the information.
The temperature of steelmaking needs to be higher, and it needs to reach above 1800 degrees.
This broken furnace can hardly raise the temperature to 1,000 degrees, let alone making steel.
It seems that in order to produce qualified steel, these furnaces need to be modified.
In order to establish the steelmaking and spinning industry in Junyangfang, Yang Fan consulted a lot of information, and of course he knew some of the contents.
And if he followed some modern steel-making methods, he might be able to promote the first industrial revolution in the Tang Dynasty.
Uh, Yang Fan is thinking too far.
He looked at the molten iron in the furnace and sighed in disappointment.
Using wood charcoal to make iron is probably the reason why ancient China could not directly use furnaces to make steel!
After thinking for a while, Yang Fan asked again: "Why not use stone carbon to increase the furnace temperature, but use wood charcoal."
In Yang Fan's view, charcoal can only be used to extract molten iron, while coal can potentially be used to extract steel.
Before Li Zhi could answer, a strange voice came.
"Oh, Wannian is really eye-opening. I don't understand such simple common sense."
"As we all know, although stone carbon can increase the furnace temperature, the molten iron, although hard, is very brittle and is not suitable for refining refined steel at all."
"I thought that His Majesty appointed you as the technical person in charge because you know more, but I didn't know that you are a completely ignorant person. You have betrayed His Majesty's trust. You should just resign from His Majesty, otherwise it will be easy to lose face. Show your eyes."
Yang Fan turned around to look, but he didn't know that Chang Sun Chong and several people in green official uniforms were not far away, following them step by step.
At this time, these people were looking at Yang Fan with a playful expression.
Yang Fan frowned.
In his opinion, these people are just clowns!
Of course he knew that the ancient iron smelting industry had long been plagued by excessive levels of sulfur and phosphorus. This was probably due to poor iron smelting quality.
However, using coal can save charcoal, increase the furnace temperature, and make it easier to extract refined iron or steel with a higher impurity content, which reduces the cost of iron and steelmaking.
In fact, the solution to high sulfur and phosphorus content is very simple, which is to refine coke and use coke to smelt iron.
However, the Tang Dynasty did not know how to make coke!
Although coke has been extracted in Junyangfang, Yang Fan could not explain the difference between coke and coal to these ancient people.
It's even harder to explain to them what sulfur, phosphorus... these things are.
So, Yang Fan didn't want to pay attention.
But Yang Fan's tolerance made these people think it was weakness, and they couldn't help but burst into laughter.
In their view, the law does not punish the public, and Yang Fan did not dare to do anything to them even if he wanted to cause trouble.
Seeing Yang Fan's face turn gloomy, Li Zhi quickly pulled Yang Fan's sleeves and reminded anxiously: "Brother-in-law, please be patient, these people are children of aristocratic families, if you touch them, it may be very troublesome! "
