Fifty thousand taels of silver, to be honest, in Jia Changchao's subordinates often spend hundreds of thousands of taels of silver, it is not a matter to take it out, not to mention that the fifty thousand taels of silver were not given to Xu Deshan all at once, Xu Deshan every step he took, he had to find Jia Changchao to explain the situation, and then Jia Changchao returned to Xu Deshan to allocate the silver taels, so that Jia Changchao could effectively supervise Xu Deshan's actions, and also be able to prevent Xu Deshan from encountering losses, even if Xu Deshan used the 50,000 taels of silver and failed to make 40,000 ordnance, At the very least, it can be called that 50,000 taels of silver have not been spent in vain.

Xu Deshan agreed with Jia Changchao's suggestion, after all, Jia Changchao is the representative of the construction party, and the contractor must consider the opinions of the construction party, pay in installments, and follow the step-by-step schedule, which is also the work rhythm that Xu Deshan likes.

Of course, in order to persuade Jia Changchao to give him start-up funds, it was useless to rely on tricks, Xu Deshan still needed to come up with something real, and Xu Deshan took out two kinds of things that were enough to make Jia Changchao forget all the unpleasant things in the morning, steelmaking blast furnace and composite bow drawings.

Xu Deshan first gave Jia Changchao a drawing of the steelmaking blast furnace, of course, it is a three-dimensional drawing drawn with charcoal, but there is no size on it, just a rough drawing, Jia Changchao looked at the side, Xu Deshan explained "Yesterday I went to the foundry to see our existing steelmaking furnace, and also saw that they burned a furnace of molten steel, how to say, although they thought that this is already the most advanced technology available, but I think that on this steel furnace, it can be slightly improved, for example, like the picture." ”

Xu Deshan said, and quickly pointed out a few places to Jia Changchao, asking Jia Changchao to take a closer look.

Poor Jia Changchao, he was born in liberal arts and read the poetry of a sage, but the sage has not learned what a steelmaking furnace is like, even if Jia Changchao has some theoretical foundation, but Xu Deshan's fingers are pointing quickly, Jia Changchao has not seen exactly what the place is, Xu Deshan took his hand back, Xu Deshan also widened his eyes and asked Jia Changchao to take a closer look, what else to see, even if he stared out his eyes, he couldn't understand it.

Jia Changchao knew that this was not what he was good at, so he simply put down the drawings in his hand and asked directly, "Xu Deshan, just say it directly, if it is made according to a blast furnace like yours, what is the difference between it and the existing steel furnace." ”

Xu Deshan said with a smile, "If the adult asks about the technology or the details, if it is technical, we can talk about it for a day and a night, if it is the result, that is, what is smelted with my steel furnace is real steel." ”

Jia Changchao still didn't understand what this meant, and asked, "What is real steel?" ”

Xu Deshan said, "This ...... After the iron is smelted, the adults will see it for themselves. ”

Xu Deshan's personality, Jia Changchao is still clear, since Xu Deshan said yes, then most of the time it is, Jia Changchao sighed in his heart, this Xu Deshan, wouldn't really dream of any immortals, otherwise he was four years old, how could he just go to the casting place to take a look, and then transform the steelmaking furnace of others, if it is not a god, even if it is a saint in the next life, there is no such ability.

Jia Changchao suppressed the horror in his heart and asked, "Xu Deshan, are you sure that your blast furnace can have an effect, don't pat your head and ask for nonsense." ”

Xu Deshan hesitated for a moment and said, "To be honest, no." ”

Jia Changchao wanted to listen to Xu Deshan say something to give himself some confidence, but he didn't expect Xu Deshan to say such a thing, and he almost didn't get angry, and Xu Deshan continued, "However, I still have one thing here, look at it, just this thing, can you give me the down payment first." ”

Jia Changchao was stunned for a moment and asked, "What else do you want me to see?" ”

Xu Deshan handed over another drawing in his hand, it was still a three-dimensional diagram, there were no parameters, and while handing it to Jia Changchao, he said, "My lord, this picture is a little simpler, you should be able to understand it." ”

"I ...... If you have something to say, if you have a fart, let it go! Jia Changchao almost slapped the table.

Xu Deshan said, "My lord, I saw it, this is a drawing of a bow. ”

Jia Changchao said, "Nonsense, I can't see that this is a bow, I'm asking you what's special about this bow." ”

Xu Deshan stretched out his hand to Jia Changchao and said, "Look here, here, and here, this bow optimizes the mechanical structure by using pulleys, how to describe it specifically, well, how far can the best archer in our army shoot the bow and arrow?" ”

Jia Changchao thought for a while and said, "If it is this kind of ordinary bow and arrow, if it shoots directly, it will be about dozens of meters." ”

Xu Deshan said, "That's fine, with my bow, the range of the arrow should be easily doubled." ”

“……”

Before Xu Deshan took the blast furnace drawings, Jia Changchao looked more general, no concept, now after the actual data, Jia Changchao can feel how shocked Xu Deshan took the things, bow and arrow, the reason why it can have such power, is not it brought by ultra-long range, of course, on the battlefield bows and arrows generally have no chance of flat shooting, most of them are projectiles, flat shooting dozens of meters, the projectile distance is about two hundred meters, even if such a distance, It was already the biggest barrier for the Song army to block the Liao army, if Xu Deshan could double this distance out of thin air, and with the cooperation of the troops, Jia Changchao doubted that the cavalry of the Liao State could break through his own arrow rain.

Jia Changchao's

The hand suddenly became excited, Jia Changchao is a gentleman, but the same is a gentleman, and it is also divided into several kinds, there is a kind of real gentleman, self-cultivation inside, external governance, entering can calm the world, expand the territory, retreat can stabilize the government, cultivate and benefit the people, proficient in everything, good at everything, and there is another kind of gentleman, their personal character is no problem, like what to give the money to the uncle of the servant, help the old man cross the road, etc., can do it, but their Confucian poetry and books may have read a little too much, and they read the truth to death, Whatever the book says, they will do it, there is no flexibility and keeping pace with the times, guarding their stubborn truths, they can harm the world's major events, and small ones can make the court unstable and people panic.

Fortunately, Jia Changchao belonged to the former, otherwise he would not have valued Xu Deshan so much, when he heard the power of the compound bow described by Xu Deshan, he stood up from the chair excitedly and asked, "Are you serious?" ”

Xu Deshan touched his nose and said, "Theoretically, that's the case, but if you want to make this kind of bow and arrow, you still need several conditions." ”

Jia Changchao hurriedly asked, "What conditions?" ”

Xu Deshan said, "First, it is necessary to build the blast furnace I am talking about, and the steel that these craftsmen have trained is so bad that they can't make the parts of this composite bow." ”

Jia Changchao nodded and said, "This is no problem. ”

Xu Deshan said, "Also, if you want to make this kind of bow and arrow, then ...... The money will have to be calculated separately, and it is not known how much such a bow will cost, but if the plan goes well, the price should be between two taels and three taels of silver. ”

Jia Changchao listened, and couldn't help but call this bow worthless, you said that such a good bow and arrow, how could it be an inventor like Xu Deshan, if it is as Xu Deshan said, the compound bow can have such a large range and power, and Xu Deshan, who can create such a battlefield weapon, will inevitably leave a name for eternity, in this great time, how can Xu Deshan only think of money.

Jia Changchao asked again, "Xu Deshan, can you be sure that this compound bow you said can be so powerful?" ”

Xu Deshan said, "Not yet, I don't know if the craftsmen here can't learn my steelmaking technology, and how their processing technology is, if it's good, the range will increase, if it's not good, it's ......"

Jia Changchao hurriedly asked, "What will happen?" ”

Xu Deshan said, "If it's not good, the range can only be increased by half, but this also has the advantage, that is, the price can also be correspondingly cheaper." ”

Even half of it is amazing, Jia Changchao hurriedly said, "Then I will give you another thousand taels of silver, and you can make me four hundred to take a look." ”

Xu Deshan shook his head and said, "If you only need four hundred, it will be more than one thousand taels of silver." ”

Jia Changchao said, "Why is this, didn't you just say two or three taels of silver?" ”

Xu Deshan said, "That's different, how can the cost of large-scale production be the same as that of small-batch production, if you only need a few hundred, the price may have to double and double, ten taels of silver." ”

Jia Changchao was a little distressed, gritted his teeth and said, "Then a thousand taels of silver, a hundred, you must make it for me." ”

Xu Deshan sighed and said, "Don't be that kind of tone, I'll make a bow and arrow for you, I'm still suffering a big loss here, have you ever thought about how much I can value just this drawing, I dare to say, if I go to the Liao country, I'm afraid that the lord of the country will see it, and he can use a king of the Southern Courtyard to exchange this drawing with me, but I only exchanged a few hundred taels of silver for you with a drawing, and you said that I was not wronged." ”

When Jia Changchao heard Xu Deshan say this, he also felt a little reluctant in his heart, and asked tentatively, "Then I'll add some more silver to you?" ”

Xu Deshan said, "Well, then you don't have to, you hurry up and get me the money, I have to go to the foundry to teach them how to change the blast furnace." ”

Jia Changchao just wanted Xu Deshan to go, but suddenly reacted, hurriedly stopped Xu Deshan, and said, "Xu Deshan, you go slowly first, things don't seem right, let's start from the beginning, didn't we say at the beginning, are we going to build 40,000 sets of ordnance, why did you suddenly take out these two drawings, you want to change the blast furnace, make bows and arrows, what about the ordnance, you and I made a military order." ”

Xu Deshan said, "This is not simple, I have already said, use market means to solve it." ”

Jia Changchao asked, "What kind of market means?" ”

Xu Deshan said, "Since the adults asked, then I will explain to the adults, the market means I am talking about, divided into two kinds, the first is the labor cost, you think, since the cost of finding those craftsmen to make ordnance is high, we can find others to do it, anyway, it is all those processes, craftsmen are people, others are also people, how can only craftsmen do it, and others can't do it." ”

Jia Changchao frowned and said, "It's not like this, the reason why the craftsman asks for a high price is because people have that kind of craftsmanship, how can they find a random one and make an ordnance, then my Da Song Dynasty is not a mess." ”

Xu Deshan smiled proudly, "In normal times, it is naturally not good, but when it is in my hands, it is fine, otherwise, how can I be worth 50,000 taels of silver alone." ”

Jia Changchao said, "If you want to find ordinary people, I don't care what your price is or how you workmanship, but I am a Great Song Dynasty ordnance manufacturer, a wallet and a spear or something, but the bow and arrow are."

If a person is asked to steal the method of controlled goods, then the person has bad intentions, and won't it cause chaos in the world? ”

Xu Deshan smiled and said, "My lord, don't you know my methods, don't worry, even if there are many people here, I won't ask them to learn how to make ordnance, and besides, my compound bow is not as good as your bow and arrow baby, I'm not afraid of being stolen by others, what are you afraid of?" ”

Jia Changchao said, "No, no, this is a big deal, you talk about your method first." ”

Xu Deshan said, "Don't say it, if I say it, my method will not be new, maybe you won't give me the silver, there is a lot of money in it, I said it must be fine, you can't believe me so much." ”

Jia Changchao shook his head and said, "Since I promised to give you the money, are you still afraid that I will regret it, you have to believe me." ”

The two looked at each other like this for a while, Jia Changchao was waiting for Xu Deshan to make concessions, and Xu Deshan's reaction was even more straightforward, directly bypassing the topic, and said, "Let's discuss another of my methods next." ”

Jia Changchao knew that it was impossible to get something out of Xu Deshan's mouth, not because Jia Changchao had no way, but because the topic that Xu Deshan was mentioning now was also attention-grabbing.

Xu Deshan said, "Our first topic is to discuss the substitution of human resources, so now, let's discuss the substitution of production materials." ”

Jia Changchao asked, "What are production materials?" ”

Xu Deshan said, "The materials used for production are the materials used to make ordnance, such as iron and wood ropes, and so on. ”

Jia Changchao was puzzled: "How to replace this?" ”

Xu Deshan said, "There are no other things to replace, but we have iron, as long as the design is reasonable, cast iron parts can replace a large part of things, and it is durable and durable, and the damage rate is low." ”

If he said something else, Jia Changchao might still believe it, but if he wanted to exchange the original wood of the ordnance for city rail, it would be cheaper, and he wouldn't believe it if he killed Jia Changchao, how much is a pound of wood, how much is a pound of iron, this account, anyone will calculate it, how can Xu Deshan talk nonsense and lie to himself as an old man.

Jia Changchao was a little unhappy, sat on the chair, and said slowly, "Xu Deshan, why do you say that parts made of iron can be cheaper than wood?" ”

Xu Deshan said, "My lord, you think, the wood to make things, for example, want to process a bow, you need a craftsman to carefully ponder, carefully carved, the wood itself is not expensive, but counting the time of the craftsman processing is expensive, but if we use iron, a pot of molten steel out, I can cast countless parts, of course, this also depends on the quality of the blast furnace I designed, if the quality is good, such parts can be done more, if the quality is poor, you can only do a little less." ”

Jia Changchao nodded and said, "If you say that, there is some truth, but if you do this, you can be a little sure." ”

Xu Deshan said, "Look at it......"

To tell the truth, Jia Changchao has nothing to do with Xu Deshan, you listen to these things that Xu Deshan told himself, there is not a single practical thing, all of them are imagined by Xu Deshan, you know, this is not a trivial matter, the cost of tens of thousands of taels of silver, where can Xu Deshan be so fooled.

But Jia Changchao had the intention to ignore Xu Deshan, but he was also reluctant, there was no way, the big cake drawn by Xu Deshan was too big and too fragrant, if it could succeed this time, then whether it was steel or composite bow or this way of producing ordnance, it would cause a big earthquake to the long-dull society of the Song Dynasty, and the people couldn't imagine what the people were, but it was certain that the strength of the two long-standing hostile countries of the Song Dynasty and Liaoxia could be reversed at once.

In the face of the foreseeable bright future, Jia Changchao gritted his teeth, this silver, even if it is for Xu Deshan to be wasted, as long as there is hope for success, then this silver will not be in vain.

For Xu Deshan's plan to succeed this time, Jia Changchao made a bloody investment, not only allocated 10,000 taels to Xu Deshan's family at one time, but also worried about Xu Deshan's safety problems, and deliberately put his own guard, that is, Zhou Di, who dared to arrest Zhizhou Liu Xian, and ten guards were sent to Xu Deshan's side to protect Xu Deshan, and the word was passed to all yamen, as long as Xu Deshan went, he must try his best to cooperate, and there can be no obstruction.

In this way, a great change that gathered all the forces of the entire Daimyo Mansion began, and a five-year-old child became the leader of this change, of course, this change did not touch the essence of the Song Dynasty, the Great Song Dynasty is still the Great Song Dynasty, Xu Deshan just injected the technological productivity of the leading era into the Great Song Dynasty out of thin air, neither offended anyone's interests, nor touched any political forbidden areas, so Xu Deshan's actions were supported by everyone in the Daimyo's Mansion.

About this matter, Jia Changchao specially wrote a letter, after reporting this matter to the Kaifeng Imperial City, just like that, Xu Deshan's name appeared for the first time on the dragon book case of Emperor Zhao Zhen, Zhao Zhen looked at Jia Changchao's book very seriously, and looked at Xu Deshan's name, he was silent for a long time, and he couldn't see whether Zhao Zhen was happy or humble, angry or shocked, after staying for a long time, Zhao Zhen picked up the red pen, drew a big circle on the fold, and then wrote it down by himself, and after the success, Jia Changchao took Xu Deshan to the palace.
