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

Once again, Hua Manlou is just an ordinary modern person with a wide range of knowledge.

He is not smarter than those of this year, nor is he more skilled than the craftsmen of this year, and he does not have those messy cheats—in fact, he had fantasized about this when he just came here, not to mention, It’s okay to give a Du Niang, knowledge is power!

However, it has been several years since he wore it, and he neither burst out with special talent nor suddenly had a male and female voice speaking in his mind after a 'ding' sound, nor did a transparent panel pop up suddenly to give him a glimpse. There are a lot of tasks, but there is a bit more memory, but most of them are the scenes of being beaten by his father, or the anxiety of losing red eyes in the casino...

So all he can rely on is the knowledge of several hundred years more, and it has to be the kind of knowledge that has a table of contents and provisions, that's all.

Therefore, he can quickly promote development in some shallow areas, and he can provide correct ideas in some areas, but if he is omnipotent enough to handle everything, then...

It's unrealistic, unless he brings Du Niang with him.

After all, his previous life was in an era when social division of labor became more and more detailed. Many people can specialize in one field. If they expect to make achievements in all fields... or multiple fields, it is very likely that they will accomplish nothing.

Therefore, the essential purpose of Huamanlou teaching physics to this group of people before is to let them follow this direction, use theory to guide practice, and continue to summarize theory while practicing, thus forming a virtuous circle and then promoting development. That's right, after all...

It is difficult for a strong man to let him promote the development of science and technology alone.

And in this idea, the role he plays is the employer, or the father of Party A. At best, he just controls the direction of development. It can be seen that Party A has changed its needs, but I have never seen Party A participate in research and development together...

Oh, changing needs is probably considered participation, such as mentioning the colorful black, colorful green and other demands that torture people.

But looking at the appearance of this group of people now, they seem to regard Huamanlou as omniscient and omniscient. It was an extremely smooth road, so this group of people got used to relying on him.

But this method is not healthy, because technological progress is often carried out through trial and error-one step is good, it can save a lot of time, money, energy, and resources, but what is lost is the possibility and A lot of experience, which will limit the development of these people to some extent, and...

Huamanlou doesn't have that much energy to follow up with every project, let alone the ability to follow up with every project—it's all in a catalog. If you want to tinker, don't you have to start from the most basic place?

But a good time is used for scientific research, it is like torture for a salted fish, so...

"Everyone." Hua Manlou calmed everyone down again, and then said slowly: "I know that everyone wants to achieve results as soon as possible, and I also know that the things you research will generally lead to some innovations or even complete changes. , I hope that everyone can come up with something beyond my imagination..."

Speaking of this, everyone knows that there is a "but" behind it, so many people are eager to talk, but Hua Manlou waved their hands to signal them to be quiet, and then said slowly: "But, I am not omniscient, and I am not omniscient, and I am not omniscient. It’s not going to be helpful to everyone everywhere.”

After hearing this, everyone was quiet.

Hua Manlou continued: "The so-called 'three people walk together, there must be my teacher', this is not Confucius teaching people to be humble, but a complete statement of a fact. For example, some of you Some people are good at making iron, some are good at carpentry, some are good at farming, and some are even good at calligraphy, all these are enough to be my teachers.”

"Everyone, you are all people with special skills, and you are all able to shine in your respective fields. Of course, what you do is also the most cutting-edge in your field, such as rifling. Rifling?"

"Of course, I know that I was the one who said this thing, even the name, but I proposed it, and you guys finished it." Hua Manlou patted the shoulder of the blacksmith beside him and said, "What I have done It is known that rifling can improve the power and accuracy of firearms, but how to make rifling and what kind of rifling is useful is up to you to experiment.”

Hua Manlou's voice suddenly increased: "So what I mean is, I am responsible for thinking up some things, and then provide you with everything that can be provided, and you are responsible for creating these things that I have thought of against all odds. Yes, otherwise, what use are you waiting for?"

The last sentence was a bit heavy, but everyone looked at each other for a while after listening to it, and then they all lowered their heads in embarrassment—the purpose of most people coming to Huamanlou is actually very clear, and it is all in order to get rid of Huamanlou as soon as possible. The things are made so that they can get bonuses and share, but everyone subconsciously ignores a problem: Huamanlou let them live and work in Xishan, and his purpose is basically to let them do these things, and if he can do it all by himself, then he can't do it. Why should they?

This is like the landlord’s family hiring a long-term worker, but the long-term worker ran to pull the landlord to do things together while doing things. How can there be such a reason?

This is also the case for those scholars who came to Xishan to be punished. Even if they have voluntarily joined the Polytechnic University, they have not yet finished what they should do. In theory, they are prisoners receiving labor reform, which is worse than long-term labor , Where are they qualified to discuss productivity with Huamanlou?

"Have you figured it out?" Hua Manlou looked at the silent crowd, and continued: "Go back when you figure it out, and use all your ingenuity to try to solve the problem. As I said just now, what you have studied All of you are at the top of your profession, so you should be the ones who know the most about those things in this world, and the solution to the problem is in your hands, so why don’t you come to me just for the sake of it?”

After Hua Manlou finished speaking, he left slowly, leaving a group of people standing there in shame.

After a long time, Liu Tiezhu raised his head to look at the people standing beside him, sighed and said, "Did you hear what Lord Hou said? If you heard it, you all go back to work!"

After saying that, the old man also left, and everyone was embarrassed for a while when they saw this, and then they dispersed in a hurry.

As everyone knows, after walking for a while, Huamanlou hid behind a rock and looked at the situation here. Seeing that this group of people seemed to be persuaded by him, he wiped off the sweat that didn't exist on his forehead and let out a sigh of relief. : "Huh... Fortunately, I can fool you! Otherwise, would it be possible to really engage in research and development with them? I am Party A!"

652. Scarlet letters on a white background

Huamanlou's trickery finally established her position as Party A in Xishan, which has two meanings.

As a result, the group of people in Xishan can only find ways to solve all technical problems on their own, while Huamanlou, as he said, only provides a platform and financial support, at most it is just like Party A to mention it in the past.

To a certain extent, this is the normal way of technological progress—it was also the case in most of Huamanlou's previous lives. People with projects seek sponsors to attract investment, and then round after round of financing. The only difference is that this Group craftsmen don't need to find it themselves, Huamanlou directly provides support.

Now, Huamanlou no longer has to hide from these craftsmen, and can finally catch fish openly - this is very important, salted fish...

"So this is the surprise you gave me?" Hua Manlou hugged Miss Wen with one hand, pointed to the pile of samples and project applications on the table with the other, and smiled angrily: "It's been almost half a month since I returned to the capital, and I'm going back to Beijing." It's been several days in Xishan, and you've never leaked a word!"

This room is a special place for Wenliang to store samples. Except for a large table, there are a bunch of shelves, large and small, filled with all kinds of weird things.

Leaning in Huamanlou's arms, Wen Liang smiled and said, "Do you still like this surprise husband?"

Hua Manlou clicked his tongue, then gritted his teeth and said, "I like it, I like it so much, don't leave at night, let's fight till dawn."

Wen Liang gave Huamanlou a white look, and then introduced to Huamanlou the situation of Xishan in the past six months.

The rifling technique that Liu Tiezhu has been putting on his mouth is actually very good at present. After all, Huamanlou mentioned this thing as early as two years ago, so Lao Liu tinkered with it from time to time. The firecracker in the hand of the precise shooter who shined when King Duan assassinated Emperor Guangxing was the first-generation rifled gun that had already been formed.

The only problem is that at that time the rifling was scraped out by hand with a scraper, not to mention the time-consuming and labor-intensive production, and the rifling was also very worn, so Liu Tiezhu has been trying to solve the problems of accuracy and efficiency.

Then with the help of carpenters, Lao Liu really thought of a solution: to make a lathe specially used for rifling.

The method is actually very simple. He fixes the hook knife on a pull rod, and when the pull rod is pulled, the barrel rotates at a constant speed, so that a rifling line with a certain degree of winding can be broached. After reaching the predetermined width, he can change the position and pull the second Rifling, the more times you pull, the thinner and more precise the grooves will be.

This method is similar to the method used by the bandits in the early West when they played colonization, commonly known as the hook knife broaching method.

This method was quickly recognized by everyone, but Lao Liu still felt that it was a bit rough and complicated, so what he wants to overcome now is to manufacture a lathe that can pull out all qualified rifling at one time, so that the quality can be increased. It can be guaranteed - that is to say, he is stuck at this step now.

Under Wen Liang's introduction, Hua Manlou looked at the blueprint and held his mouth in his throat, wanting to vomit: Who the hell would do this!Liu Tiezhu, you have thick eyebrows and big eyes, you actually want to pull the young master to study this thing with you?

Suppressing the desire to curse, Hua Manlou turned his attention to the non-military items, and the first thing he saw were chains and gears.

It was only after seeing this picture that Huamanlou remembered that this thing was mentioned when he gave this group of people a physics class. At that time, he was talking about levers and roller skating. Then he gave the example of gears, saying that this thing can Try building a tricycle...

Not long after that, someone reported the project, Wen Liang heard what Hua Manlou had said, and approved it.

Judging from the reported progress of the project, the group of blacksmiths has already understood the working principle of this thing, and successfully found a suitable alloy in the material class, and successfully built two gears, but the chain made this group of people It's a little tricky: it's not easy to tinker with a chain that's strong and works.

You must know that many things are developed by groping, and most of the small things are done by hand by craftsmen. Unless it has proven its value, craftsmen will find ways to improve efficiency, such as rifling and bearing parts. That's it.

But the problem is that the precision of handmade things is often not high, and the chain has to fit the gears, so the things craftsmen have made several times are barely usable, so they urgently hope that Huamanlou can help They want to see what the finished product will look like.

But even so, their progress is already quite gratifying. From Hua Manlou's point of view, even without his help, this group of people can get things done in a short period of time. Maybe it won't take long for the tricycle to come out—don't worry. Forgot, there is another person who studies spokes, the only trouble that person encounters now is how to combine these things...

It has to be said that the huge wealth created after the advent of the new carriage made many people in Xishan go crazy with jealousy - think about it, even Emperor Guangxing sent Xu Dacheng to collect Zhao Ren's share, let alone others?

Although the price of the new carriage is very high, it still makes many people start to focus on the development of things for civilian use, so this part of the project applications is the most.

For example, in the sample area, Huamanlou saw a very familiar thing: an enamel cup.

In fact, this thing is not technically difficult at all. It is nothing more than making a metal cup and coating it with a layer of enamel. According to the current Da Zhao's cloisonné craftsmanship, this thing is completely pediatrics, but...

"Who made this thing? Why hasn't it been produced?" Hua Manlou picked up the enamel cup with a look of surprise on his face: "It's a good thing!"

Wen Liang thought for a while, and replied: "This is made by a porcelain maker. He thinks this kind of cup is more durable and strong, but I think... well, it may not be sold, so there is no approval."

Hua Manlou was stunned for a moment before he suddenly realized, he pinched his warm nose and smiled, "Miss, do you think that others will drink tea slowly with a good tureen like you? Not to mention, The set of blue and white porcelain in your study is probably enough for a family of eight to feed for two years, do you think the common people can afford it? The common people use rough porcelain bowls, okay?"

I have to say that Miss Wen's political wisdom is quite brilliant, and she is also quite neat when dealing with Xishan affairs, but she still has to be a little confused about this kind of matter - or, she always thinks that everything that Huamanlou fiddles with should be tall and tall. on, but I have no idea about this kind of gadget.

So when Hua Manlou said this, she blushed a little: "Is...is that so?"

Hua Manlou smiled and said: "This thing is cheap, strong and light, and it can be used as a vessel for cooking or boiling water when the tools are not complete. Not to mention the common people, it is also a great weapon in the army , hang it on your body and you will have something for drinking water... Well, just call someone here, I want him to customize one for me, but I don't know if the red word can be written..."

Wen Liang asked suspiciously, "What word?"

Hua Manlou smiled but did not answer.

Red letters on a white background, Grandpa Mao's handwriting, tsk tsk, it's so touching...

653. Really good

Huamanlou had an enamel rice bowl when he was in college. It was very beautiful. He used it to smash old Mr. Jin and his cousin... Oh, that was Liu Lili.

But to be honest, enamel products are really easy to use at certain times, such as making instant noodles. The instant noodles cooked with alcohol lamps in the dormitory in the past, I don’t know why they are so fragrant, so aftertaste...

Of course, this dangerous behavior is still not advocated, and it is better to use an induction cooker.

Enamel products that still had a huge market in Huamanlou’s previous life will not be so low in this era—think about it, rough porcelain bowls are fragile and not easy to carry, but enamel bowls can perfectly solve these problems , if you use it carefully, it can last for a long time, and it can be taken to the field to work, and it can be placed directly by the stove in winter. It is really a good thing.

Enamel seems to be a simple gadget, but the speed of raising money is no slower than that of a horse-drawn carriage, and it is also a monopoly business-now there is no new type of iron-making place except Xishan and Lanzhou. Others make such an enamel product The cost of making it is not low, so even if you want to grab this deal, you can't take it away.

So, where can the traveler not get a few tons of silver?

Putting down the slightly ugly enamel cup, Hua Manlou personally drew a few patterns such as the cup and the rice bowl, and then added a five-pointed star on the cup with a look of nostalgia, and wrote the words 'serve the people' , someone took it to the porcelain maker and asked him to make one by himself. If he can pass the quality test, he will be the director of the enamel factory.

After finishing these, Hua Manlou continued to walk around the sample room with Wen Liang in his arms, and then he was attracted by a very strange thing.

"This is?"

It was a strange looking thing, one end was a wooden plank with something like a rope attached to it, and the other end was something like an empty bag.

When Wen Liang saw the thing, he pulled Hua Manlou away, and then said angrily and funnyly, "It's cow urine bubbles, and sheep intestines, I forgot it was still thrown here."

"... Huh?" Hua Manlou pointed at the thing, with a dull expression on his face: "This is... from the cook? Are you planning to make peeing beef balls?"

Wen Liang shook her head and smiled, "No, they said that thing was a mine."

"Water..." After Hua Manlou looked at the thing again, he suddenly understood.

There is a pipe on the wooden board, which seems to be connected with sheep intestines to the bag below... the cow urine foam is used to ventilate, and the cow urine foam is filled with black powder—of course, because it is a sample, so it is not installed now—it is still set A small device for delayed triggering: incense sticks.

I have to say that this thing seems very rough, and it is difficult to control the time of delayed explosion, but it is definitely a usable mine-in fact, the Ming Dynasty also had the same thing, and it was called the underwater dragon king gun at that time , is the earliest floating mine in the world.

"Although it's pretty silly, the way of thinking is still commendable... right?" Hua Manlou smiled wryly, "It's just that this thing will rot and stink after a long time, right?"

The idea is of course worthy of praise, after all, it is the world's first mine, but it is not easy to store...

Wen Liang nodded again and again, and then said: "This is from the Maritime Academy. When it was delivered, I happened to meet a few scholars, and the two sides chatted for some reason. Then the scholar said that they could make a kind of water that can be put into water." They left with the iron-shell mine that didn’t sink to the bottom, but it was just left here, fortunately it was only a few days after it was delivered..."

Can iron shell mines be built?

Yes, as long as you master buoyancy, and Huamanlou has indeed told these people about buoyancy, so it is estimated that there will be a finished product in a short time, and it may be triggered— —Similarly, the first sea mine in Huamanlou’s previous life that produced results was the underwater mine of the Ming Dynasty, which blew up Japanese pirate ships. It was nearly three centuries earlier than the sea mines used in the first Russo-Japanese War...

Hua Manlou shook his head in admiration: "Isn't this pretty easy to toss around? But it's enough to keep a record of this thing. Throw away the real thing. It will stink after two days."

Wen Liang nodded, recruited someone to enter the room and threw the cow urine foam out, then took Hua Manlou to the other side, pointed to a few bamboo-like things and said, "Here, these are also sent by the Maritime Academy."

"What is this?"

The bamboo is about one meter long, hollow in the middle, with a pointed head and four bamboo tubes at the end, which looks like a model rocket.

"They said that this thing is called a fire dragon coming out of water." Wen Liang pointed to the four bamboo tubes at the back and said: "First, these four bamboo tubes push forward with all their strength, and after the gunpowder inside is burned, continue to be pushed by the middle bamboo tube, which is said to be able to leap up to eight miles In addition, it is used to attack ships far away. They are still thinking about how to install a Pudu on this bamboo..."

Hua Man Lou: What a rocket!And it is still a rocket with the principle of rocket series and parallel connection!And install Purdue...

In the end, wouldn't it become an anti-ship missile?

"Maritime Academy... What a group of talents!" Hua Manlou sighed sincerely this time.

No exaggeration, they are all talented people, because the conditions at the Maritime Academy are not as good as those in Xishan—you can see from the things they make, these things are made with local materials, full of a very simple smell.

What's more, they lack Huamanlou, a person with advanced vision, than Xishan. No one there provides them with such ideas, as well as basic physics—such as mines. Have an idea?

"I have to add some budget to the Maritime Academy, and I have to send someone to popularize physics for them..." Hua Manlou felt very relieved: If they were all like the Maritime Academy, how much peace of mind it would be!

Wen Liang misunderstood what Hua Manlou meant when she heard this, she curled her lips and said, "Don't you think these people are too enthusiastic about researching weapons? Especially when you go out to fight, most of what you hand in are weapons !"

"well enough?"

"There are more over there!" Wen Liang took Hua Manlou to the corner, pointed to a round thing like an iron pot on the ground and said, "Here, guess what it is?"

Hua Manlou squatted down and picked up the thing to look at: "This is... a landmine?"

Judging from the appearance, this thing is an iron-clad jar with something that looks like a trigger device, which can be ignited by stepping on it.

In fact, the first landmine and the first anti-injury landmine in Huamanlou's previous life also came in the Ming Dynasty, and it was often used in the fight against the Japanese, so it is not surprising to research the landmine now.

Wen Liang nodded: "It was sent by the New Military Academy. They think this thing is a more powerful weapon than Purdue, and it is very convenient to use. It only needs to be buried on the road that the enemy must pass."

Hua Manlou shook his head and sighed: "It's really good, you can tinker with this thing? Is there anything else?"

(Who is it that said to find information for me?)

654. The ancient version...

As Wen Liang said, the highest proportion of submissions in Xishan in the past six months is still weapons.

A person from the New Military Academy found a few blacksmiths who had no projects in hand, and wanted to jointly develop a repeating gun.

This man, who was originally Xishanwei, injured his leg while fighting Japanese pirates in Ningbo. Later, he changed his job to a civilian job and became a firecracker instructor at the New Military Academy.
