As a salted fish, I was forced to become the teacher of all ages

Estum naturally knew that iron was expensive, and that iron on the grassland was even more expensive. At the most exaggerated moment, they didn't even dare to sharpen their small knives for cutting meat. .

Of course, Huamanlou’s improvement of ironmaking technology was never heard by the Oirats, so naturally they don’t know how cheap the iron in Xishan is. The policy of not causing trouble, the Wala people have not even been out of the Honglu Temple recently, so how would they know this?

"The price of iron is already expensive, and the labor required to shape iron into Pudu is even more expensive. Brother Er, do you know how much effort I spent in Xishan to recruit a group of blacksmiths? Blacksmiths are not ordinary young and strong, not everyone can get started ! So it is not easy to make a qualified Purdue, do you think these are not enough for a sheepskin?"

Hua Manlou sincerely showed how hard it was to make Purdue, but Zhao Ren who was on the side wanted to kick him twice: "Molten iron smelted in a blast furnace and poured into a mold will turn into a large number of warheads at once. How dare you lie to this honest man?" Purdue is artificially built?Want to face or not?

but……

For some reason, although he felt that Hua Manlou was extremely wicked, Zhao Ren felt extremely excited in his heart, like a little fox who stole the chicken but was not found, so...

Under such inexplicable circumstances, the Crown Prince of Da Zhao was being led more and more crookedly by Hua Manlou, and he didn't know it.

But Er Situmu had a different feeling. He faintly felt that Huamanlou was exaggerating, but after all, this was the limit of his vision. Therefore, when Huamanlou talked about the material and manufacturing of Purdue, he also felt that it was exaggerated. Can't help frowning: "Is...is that so?"

Hua Manlou pointed at Zhao Ren and said, "Of course, if you don't believe me, you can ask him! I forgot to introduce to Brother E. This is...well, he is the technical backbone of our Xishan. Brother E, don't think he is young, but he studies The things are very high-end, and he has put a lot of effort into the manufacture of Purdue and Firecrackers!"

As soon as Zhao Ren heard this, he immediately understood. He raised his chest and looked up at Er Situmu and said, "Yes, yes, this Purdue is very difficult to build, and it must not be sloppy at all! For example, the airtightness of the bullet, the gunpowder Capacity, lead wire material and length, warhead dent, etc., if there is a mistake in one place, either Purdue will fail to explode, or it will blow up itself, or the power of the explosion will not be very powerful, in short... it is very difficult!"

When Zhao Ren was tinkering with hand grenades in Huamanlou, he often heard some new words that he didn't understand, but now he threw them out regardless of whether what he said was correct or not, and Er Situm was stunned. : "So, the price... oh, the compensation is really not expensive, but... but there are too many things we lack on the grassland..."

He was telling the truth. After all, other than cattle, sheep and war horses, only cowskins and sheepskins can be traded on the grassland. They hope to exchange more food and cloth for these things. They can't all be exchanged for firearms. Bar?

Hua Manlou sighed with a look of resentment: "It's okay if brother Er doesn't want to change firearms, but... think about it, if you travel thousands of miles to get back a bunch of things with great difficulty, you end up being bullied halfway." If the Tatars are robbed, or the Tatars send troops to rob them, how do you resist?"

"This……"

"The so-called innocent people are guilty of carrying a large amount of goods back to the grassland, but if you don't have the strength to protect these things that carry the hope of your Wala's rise, then what are you planning?"

"Having said that, but..." Er Situm was at a loss for words.

The reason is correct, but the price is too scary, Wala can't afford it...

"Brother Er, the pattern! Do you know the pattern?" Hua Manlou threw down the last card: "If I were you, the first batch would definitely go back with a bunch of firearms, and then go to wipe out some tribes on the Tatar border, And then exchange their stuff for food for salt and bab, don’t you think this is a good idea? Wala people, it’s time to stand up!”

I have to say that what happened today was a bit sudden. Ever since Huamanlou entered, Erstum's scalp was numb from the series of news he dropped, and he didn't even have time to think about what to do with the firearm. But after Huamanlou was so little, he suddenly realized: That's right, after getting the firearm, you can't just watch the ashes fall, right?Gotta grab something and come back, right?

Once again, the people of the grasslands have been living in the form of tribes since ancient times. Only after a few powerful figures subdue other tribes can they form a group that looks like a country. Therefore, Tatar and Wala actually It is difficult to demarcate national boundaries, and the two sides only have a rough sphere of influence.

Therefore, perhaps the tribes that were attached to Oara a few years ago are now attached to the Tatar side, or there may be tribes that refuse to accept and take off and move westward to move closer to Oara. This is a common thing.

Under such circumstances, if Wala had such a powerful firearms force, then the tribes in the border area would naturally be in danger. If they want to survive, is there any other way than to move closer to Wala?

Oh yes, they can still die.

And naturally, in the tug-of-war between Oara and Tatar, some tribes sold Oara and defected to Tatar, causing great losses to Oara. Erstum hated it when he thought of this, so Once Wala is armed with firearms, can this revenge be avenged?

So he was moved: "What Brother Xian said is true, as expected, we should change more firearms!"

Hua Manlou said with a smile: "Since Brother Er has no objection, how about we move out of the city? Brother Er wants to see the power of Purdue, but that thing is not suitable for use in the city, and it is not justified to invite the censor."

Estum nodded, but then he was in a daze again: Wait a minute, when did I say I have no objection?I just said to buy more firearms... right?

(Already suffering from toothache, I finally fell asleep and was woken up by the crazy woman upstairs throwing things and crying and howling... But this guy was taken away by the police uncle after a while, so happy~)

160. You can learn whatever you want

Under Zhao Ren's slightly admiring and contemptuous eyes, Hua Manlou completely limped Er Situmu out of the city. Emperor Da Zhao and Er Situm signed the first 'lease' contract.

The two parties determined that the first batch of Purdue would total [-] pieces, of which [-] would be given away, [-] would be leased, and the price would be a total of [-] pieces of cowhide—that is, Huamanlou only gave Erstumu a [-]% discount.

As for the firecrackers, war horses or oxen are used for 'rental'. After Huamanlou complained about the difficulty of making firecrackers, the two set a price of one for two warhorses and one for one for cattle, and according to the price of the firecrackers One hundred rounds of bullets will be given away for each shot, and you will have to buy bullets later...

So, monopoly business is like this, you can set the price as you want, whether you like it or not...cough cough...

As for other things such as grain and salt, they are traded at market prices. Huamanlou is responsible for sending people to purchase and deliver the things to Hamiwei.

Looking at the back of Estumu going away, Zhao Ren said with a smile that was not a smile: "Tell me, if he knows the truth, will he turn against you?"

Hua Manlou smiled: "No, because he has no choice. Only with these firearms can they become stronger. Although this strength is based on our humanitarian assistance, if they don't do this, they will face It’s the destruction of the country and the extermination of the species, how would you choose for you?”

Zhao Ren's eyes widened: "You call this humanitarian aid?"

Hua Manlou said with a smile: "Ang, what else? As a vassal state of Da Zhao, when Oala couldn't survive, Da Zhao extended a helping hand to help them tide over the difficulties. Isn't this humanitarian? And..."

Hua Manlou reached out and touched Zhao Ren's dog's head: "Silly boy, do you really think that Er Situmu doesn't know that I'm exaggerating? Let me tell you, even if I don't tell him he can understand these things himself, but The reason why he didn't break up with me with a strong attitude is because he knows that if he really annoys me, he won't even be able to rent a Purdue. Besides, there are a lot of cows and sheepskins on their grasslands, but what do you think of these things? Besides us, who can eat it? Even if they can eat it, who can use so much?"

It has to be said that Zhao Renchang has not been touched on the head at such an age. After all, who would dare to rub the crown prince's dog's head except the emperor and empress?Therefore, Hua Manlou's actions made him feel very weird, but he didn't feel disgusted. On the contrary, he really felt that it was good to have an elder brother teaching himself by himself, so he let Hua Manlou act recklessly—although the few behind him 'Long Sui' turned pale with fright.

Hua Manlou continued: "Finally, remember, no matter who you tell about this, it is humanitarian aid."

Zhao Ren asked puzzled, "Why?"

Hua Manlou sighed and said: "Think about it, those old antiques in the court can't even accept the exchange market, so how can they accept us selling firearms to Wala? I told you about the benefits of the exchange market, a Wala who can compete with the Tatars I have also told you about the benefits of existence, but do you think I can tell those people in the court? Do you think everyone is as open to these things as your father?"

Zhao Ren was still a little puzzled: "But you are obviously right, why can't they make sense?"

Hua Manlou rubbed Zhao Ren's dog's head again: "Have you read "Zhuangzi Nei Pian"? It can fly for thousands of miles, with the breath of clouds, and the blue sky, but the sparrow still laughs at it. Why?"

Zhao Ren seemed to realize something: "Is it because... those old things in the court couldn't figure it out?"

Hua Manlou smiled and said, "That's right, so Zhuangzi used this story to tell us that we should never argue with idiots, because idiots don't understand my style~"

"Wow ha ha ha ha..." Zhao Ren laughed unsteadily.

Zhao Ren's smile was as low as ever, and Hua Manlou only thought that he was telling a joke. He didn't know how profoundly his influence on the future emperor of Da Zhao had been exerted by his subtle influence. Zhao Ren was just beginning to rebel. When he was old, he couldn't listen to the chatter of the old guys in Zhan Shifu, but Huamanlou was about the same age as him and the words he said were very appetizing to him, which made his three views gradually drift away from this era.

As for why the appetite...

Who do you think would explain the truth contained in "A Happy Journey" in such a down-to-earth and slightly vulgar way?

It would be fine if Zhao Ren was really the son of a civil servant, but he is the only child of Emperor Guangxing, and Emperor Guangxing felt that the big one could be saved, so he didn't plan to make a small one, so...

Whether you like it or not, Huamanlou's influence on this world is getting deeper and deeper.

……

After signing the contract with Wala, Hua Manlou felt a little worried.

Without him, it's just that it is really difficult to convey the changes here in the capital to Uncle Huai'an, and I don't know when he will get the news after sending the letter now.

Obviously, the opening of the exchange market by Dazhao is no less attractive to Tatars than it is to Oala. Therefore, the exchange market has become an extremely useful weight in the matter of pushing grace to divide Tatars, which is very useful for some tribes. And the three unlucky sons who are Tutuobuhua are even more attractive than flashy kings or acknowledging his khan status, so after Huai Anbo learned about this incident, his actions would naturally be smoother.

Just sending the letter made Huamanlou extremely painful. What could be solved with a phone call in the previous life, but now it takes a few days to send someone to deliver it, and Huai Anbo will be more dangerous if he stays on the grassland for one more day——Dad really What should I do if I get lost?

Huamanlou suddenly had the urge to develop steam engines, telegraphs, and telephones.

However, when she thought that she had enough things on her body, Hua Manlou cast her sinful eyes on Zhao Ren who was on the side: This guy is always idle, why don't you really teach him more and make this guy a better person? Great inventor?Anyway, he has already started to toss the hot air balloon, he seems to be quite enthusiastic, and his qualifications are also good...

"Why are you looking at me like that?" Sensing Hua Manlou's gaze, Zhao Ren felt a chill down his back for some reason.

Hua Manlou immediately smiled and said, "I've been in the capital for a few days, and it's almost time to go back to Xishan to make hot air balloons. Let's go tomorrow?"

Hearing this, Zhao Ren immediately said, "Shan, it's time to leave! For example, leave today and drive overnight?"

Hua Manlou smiled and said: "Not busy, why don't you go to my house first today? Some things need to be settled, and... don't you think your so-called magnetic theory is a bit rough?"

Zhao Ren was taken aback for a moment, and then said ecstatically, "I knew you played with these before! Go, go, I will let you teach me all of these today!"

"No problem, you can learn whatever you want..."

"...Why are you so talkative today?"

"Huh? Haven't I always been easy to talk to?"

161. That's the deal

Although Zhao Ren wanted to empty out Huamanlou's knowledge base about physics in a short period of time, it was obviously unrealistic.

After all, although basic physics is not so abstract, the current conditions make experiments very difficult. For example, the spring dynamometer required to verify Archimedes' principle is extremely bald, and it can't be on the steelyard, right?

What's more, it's not unreasonable to study physics in the second grade of junior high school, because the calculations involved in junior high school physics require at least a junior high school diploma, and you don't even know the multiplication formula. Where can you calculate F=(G×M?×M?)/ R? Go?

Therefore, Qiaoqiao greeted her classmate Prince with a dazed expression, and Zhao Ren also took a piece of paper from Qiaoqiao's hand that looked like a ghostly talisman: the formula for multiplication.

Suddenly, Zhao Ren faintly felt that he had more things to learn...

Having promised Zhao Ren to make a hot air balloon, Huamanlou would not lie to him. After returning to Xishan the next day, the two recruited the cobblers from Xishan to study an effective plan.

Huamanlou had said earlier that he would try using cowhide skins, but in fact, the impatient Zhao Ren had already bought a bunch of cowhide with his own money, but the problem was...

"This thing probably...can't be used." Hua Manlou held his nose and moved away from the pile of smelly cowhide.

Zhao Ren was anxious: "Why?"

Hua Manlou ignored him, but turned to the cobblers and asked, "Do you know about sheepskin rafts?"

The cobblers looked at each other and nodded, and one of them said: "Mr. Qian, the little one used to make rafts. What do you mean, you want to treat these cowhide a little bit?"

Sheepskin rafts were called leather boats in the old days. The so-called "nine bends and eighteen bends of the Yellow River, the rafts stand up and cross the river pass". The use of this thing is recorded in the "Book of the Later Han Dynasty", but its real rise was in the Guangxu period, mainly used in Qinghai. , Lanzhou to Baotou line of long-distance water freight, and until the 50s, sheepskin rafts were one of the main transportation methods in the upper reaches of the Yellow River.

The so-called Yellow River in the world is only rich, which means that the Yellow River tends to be gentle on the Hetao Plain, but in fact the upper reaches of Gansu are not so turbulent. Therefore, even after 2000, there are still rivers and rivers on the Yellow River. Sheepskin rafts exist, but they are generally only used for rafting.

The largest sheepskin raft is made of more than 600 sheepskin bags, with a load of 20-30 tons. It can be seen that the airtightness and strength of the sheepskin are good, and the weight is not heavy, so Hua Manlou decided to try it.But raw cow and sheepskin is useless, so it not only needs to be depilated with salt water, but also needs to be brushed with oil and dried for a while, so the cobbler asked this question.

Hua Manlou nodded and said: "That's right, after processing, you have to find a way to cut the cowhide into a big ball, and you have to consider the airtightness... Oh, that is, to make it airtight, it can be done Is it?"

"This..." Several cobblers looked troubled: "It's not difficult if it's sewn together, but if it's airtight..."

One of the cobblers hesitated and said, "Mr. Qian, after sticking the joint with a leather strip, can it be guaranteed to be airtight?"

Hua Manlou thought for a while: "Let's try it first, if it doesn't work, I'm thinking of other ways."

The glue of the day...

In addition to isinglass, it is leather glue, which is generally boiled with pigskin and the like, and it is heated through water when used.In addition, humans have learned to use birch bark to make tar glue as early as 20 years ago, and Hua Manlou thinks it is worth a try.

Hearing Hua Manlou's order, the cobblers immediately took action.

As the blacksmiths did before, the cobblers knew that if they could make some achievements, they would definitely get the same treatment as the blacksmiths, so they didn't hide their secrets, and some even took out their ancestral special fish. Glue production method: a mixture of animal bones, fish, milk, egg whites and the like.

Huamanlou suddenly realized that this thing is very close to modern glue, maybe it is really feasible?

In addition to the material of the balloon, Huamanlou's design uses a fishing net to make a huge net bag, which is used as the "skeleton" of the balloon to bind the hanging basket.Of course, this fishing net can not be so fine, but it must be strong.

Most of the current fishing nets are made of coarse cloth and hemp, and the so-called three-day fishing and two-day drying of the net... To be honest, it is not derogatory at this time, because the hemp fiber absorbs water and easily swells, and it is easy to rot when it is wet. No way.However, it is estimated that the hot air balloon will not take off on a rainy day, so in theory, the fishing net is available and strong enough.

As for the heating device, there is nothing to say. The only fuels available today are coal and charcoal. Therefore, after designing a light and strong stove, and adding some flame-resistant materials to the mouth of the hot air balloon, it is probably not bad. .

It has to be said that what Huamanlou has been tinkering with is much more advanced than the first hot air balloon that took off in his previous life - the hot air balloon released by the French papermakers Montgolfier brothers in the Place d'Annone on June 1783, 6. Balloons are made of paper-pasted cloth, and the seams of the cloth are buttons.Besides, their fuel is straw and firewood, and the passengers...

It's a rooster, a duck and a goat.

They also conducted the first manned test flight in the same year, and the materials used were roughly the same, so Hua Manlou felt that there was no reason why they could not succeed—at least it would not be a problem to find an unlucky rooster or duck to fly, right?

All in all, with the help of several cobblers and some young men Hua Manlou specially recruited, the world's first hot air balloon finally took shape.

On the 11nd day of the twelfth lunar month in the [-]th year of Guangxing, the weather was fine, cloudless and breezy.

The venue for the hot air balloon test flight is the school yard of the Xishan Qianhu Institute. There are four high platforms built of wood here, each of which is seven or eight feet high.The four high platforms are square, and on the top of each platform there is a teenager from Xishan Qianhu Institute. They use thick ropes to pull apart the hot air balloon on the ground to form an empty bag, waiting to be ignited.

Standing by the high platform were Huamanlou, Zhao Ren, and the anxious cobblers, plus a large group of random people such as Qi Pengfei, Qi Wanrong, etc., commenting on the hot air balloon.

"Tsk tsk, can this thing fly?" Qi Wanrong, who has been appointed as the captain of the Xishan Gendarmerie, looked up at the huge hot air balloon in front of her, and couldn't help curling her lips: "Hua Man Lou, are you crazy?"

She was smart enough not to mock Zhao Ren who was checking the hot air balloon with a nervous expression...

Hua Manlou gave her a blank look: "You said the same thing when I said earlier that the firecracker can hit a distance of one mile. What happened? If you don't understand, don't talk nonsense!"

Qi Wanrong spoke convincingly: "A firecracker is a firecracker, can this thing compare to a firecracker?"

Hua Manlou blinked: "Why don't you make a bet? If this thing can fly..."

"If you can fly, let my sister marry you!" Qi Pengwu suddenly squeezed to the two of them and interjected.

Hua Manlou was taken aback by him: "What the hell?"

Qi Pengfei on the side reacted for a moment, so he immediately echoed: "Yes, yes, you have to get a big one for the bet. If you can't fly, you can marry my sister, okay?"

Hua Manlou was dumbfounded immediately: How does this sound...whether he wins or loses, he will marry Qi Wanrong?

And Qi Wanrong stopped doing it immediately after hearing this: "Damn! If he can't fly, shouldn't he marry me?"

The Qi family brothers immediately said: "Okay, let's do it like this!"

Hua Manlou stared at Qi Wanrong in disbelief and said, "I said, are you still in a normal mind? Do you know what you just said?"

Only then did Qi Wanrong come to her senses, and she couldn't help but blushed with shame: "No... no, I mean that..."

Qi Pengfei smiled brightly: "Sister, Daddy always said that people in our Qi family always keep their word, and you can make a hole by spitting. You won't break your promise and get fat, right?"
