Great Tang princess

Kerosene is more suitable for making oil lamps than petroleum. When burning, there is not much smoke and smell, so it is a good burning material.

Moreover, the production of the oil lamp is not very difficult. At present, the experimental product has been successfully produced. Li Yuechen plans to go and have a look in two days.

If it can be done, make some first, use it in the palace for a period of time, and then sell it as a commodity.

And compared to this, Li Yuechen has another thing he plans to make, which should be able to be done with the current level of craftsmanship.

The next day came the seventeenth day of the first lunar month.The holiday of Shangyuan Festival is over, and all walks of life have started to go to work.

Shangguan Wan'er and the others entered the palace early in the morning, while Li Yuechen came to Lelou.

Wu Luolan has selected a group of young artists, waiting to develop a new program format.

Today Li Yuechen is still dressed in women's clothing, keeping a low profile.

But this low-key is only relatively speaking, after all, her identity is here.

When the entertainers learned that the princess was coming, they hurriedly saluted.

Li Yuechen waved his hand: "It's all free, I don't have much time, so I'll explain it to you today, and I will mainly rely on you to practice on your own in the future."

While speaking, let them sit down where they were, and began to explain the performance forms of drama and opera to them.

As for the script, it doesn't matter. Not only are there many stories circulating among the people, there are also ready-made scripts in the story collection published by Li Yuechen.

Even she couldn't help but wonder if she should go back and write a story of "Detective Di Renjie" for them to act out.

However, this spoof-like idea was immediately given up. It required too many people, and it did not have the expressiveness of the screen in TV dramas.

The most important thing is that Di Renjie is still alive now, playing the role of the current minister always feels a sense of disobedience.

Especially if an actor is asked to wear a dragon robe to play the emperor, it is definitely impossible to perform well in this era, and it is easy to cause many problems.

……

But not to mention, this group of young artists are quite flexible in their minds, and they quickly understood Li Yuechen's explanation.

At the same time, several artists raised their own questions in time, and Li Yuechen answered them one by one.

"In short, there are various forms of performance." Li Yuechen stood in the middle of the crowd, "For example, if two people come on stage and tell jokes together, if they can make the audience laugh, it is also a successful performance!"

"Also, I have written many stories. If someone can tell them vividly on stage and arouse the audience's interest, that's fine too."

Taking advantage of it, I also explained to them performances such as cross talk and storytelling.

Li Yuechen also knew that what she said today might trigger an entertainment revolution.

But in this day and age, it's not a big problem.

Today, the output of grain has stabilized at more than 240 catties per mu, but any better field can exceed [-] catties.

This kind of production is already a proper high production for the current population of the whole country.

Not only do you not have to worry about people starving to death, in addition to the necessary procedures such as fixed granary storage every year, there is still a lot of grain that can be used to make wine and enrich the lives of the people.

Alcohol can also promote consumption and stimulate the economy, thereby entering a virtuous circle.

The people can have enough to eat, and the development of entertainment is almost a matter of course.

……

After staying in Lelou all morning and explaining the different forms of performance to them, I asked them to go back and figure it out on their own.

I don't know that the new form of performance will be produced soon, but at least they should study it more carefully.

Li Yuechen, on the other hand, went directly to the Engineering Academy in a carriage after eating at Le Lou.

After arriving at the Engineering Academy, Pei Bishu immediately came out to greet him.

I haven't seen him for a few years, he looks a lot older, and his temples are covered with silver threads.

Seeing the princess wearing women's clothing for the first time today, I couldn't help being surprised, and even forgot to salute for a while.

It was Li Yuechen who broke the silence first: "Old Pei, long time no see."

The two have been acquaintances for many years, so Li Yuechen spoke in a more casual tone.

Only then did Pei Bishu come to his senses, and hurriedly saluted: "I've seen Her Royal Highness!"

"Free gift!"

Li Yuechen smiled, and followed him into the engineering academy.

"It's a coincidence that your Highness came down. The first batch of oil lamps have been made, and I'm about to inform His Highness."

"Well, what's the result?" Li Yuechen asked as he walked, "Is the yield rate okay?"

"Your Highness has a wonderful idea, and the results are extremely gratifying." Pei Bianshu flattered her with a smile.

Today's engineering institute, with the steam engine put into use, can be regarded as the beginning of the industry.

Although the power of this steam engine is not enough to drive large equipment, it is enough to carry out a simple assembly line.

Take this oil lamp as an example, according to Pei Bishu's introduction, the daily output is as high as fifteen!

It may sound ridiculous to be able to make fifteen oil lamps a day, but this is already a big deal.

You know, if it is purely handmade by craftsmen, it would be great to be able to make one in five or six days.

But now many parts can be made by machinery, so fifteen pieces can be made every day, and the cost has been reduced a lot.

Entering the interior of the factory building, after the craftsmen came to salute, they brought Li Yuechen to the first batch of finished products to inspect them.

The structure of this oil lamp is relatively simple, with a height of about 25 centimeters.

The chassis contains kerosene and wicks, as well as two switches.

One is used to adjust the size of the flame, and can control the opening and closing of the patch on the wick.

The other switch is to buckle the glass cover to lock it, and there is a pull ring on it, which can be carried away like a lantern.

The vent hole of the oil lamp is on the slope above, so there is no need to worry about the flame being blown out even in the face of a lot of wind.

And the brightness is much higher than that of ordinary candles. Although it cannot be compared with light bulbs, it seems to be a black technology.

After Li Yuechen checked the whole thing, he nodded in satisfaction: "Everyone has worked hard, you did a good job!"

Hearing the princess's praise, the craftsmen also laughed happily.

At the same time, I couldn't help feeling a sense of accomplishment in my heart. I really never thought that I could still make such a miraculous object in my life.

Li Yuechen put down the oil lamp in his hand: "Speaking of which, I still have something here in this palace, you can try to mass produce it..."

While speaking, he took out a piece of paper from his arms and handed it over.

This was drawn with a pencil yesterday, and it is Li Yuechen's next thing that he wants to mass-produce.

The craftsmen gathered around to look at the drawings she handed over.

Although Pei Bishu was not a craftsman, he still leaned over to take a look out of curiosity.

Although I can't read the drawings, I can understand the three words on the top of the drawings.

"May I ask Your Highness, is this item called... a lighter?"

Li Yuechen smiled and nodded slightly.

She felt that since the kerosene had already been made, the lighter should also be arranged.

For one thing, people in this era mainly use fire pockets to light fires, and they actually need to be taken out and blown on from time to time to prevent the sparks from going out inside.

And it will emit smoke in wet weather and the like. In short, there are many shortcomings.

But now that the industrial level allows it, kerosene lighters can be made instead.

At the same time, it can not only replace Huozhezi, but also represents the current national industrial level.

Usually, it can be rewarded to ministers or foreign envoys to show the power of the country and the like.

In winter, people in brothels often light up lamps and heat wine.

But in this scenario, if one of them took out a metal lighter, opened the lid, turned the fire wheel, and lit the wick, it would be another scene of pretentiousness.

Li Yuechen could almost imagine that once this lighter was made, it would soon become a must-have fashion item in the aristocratic circle and earn a lot of money.

This thing is not difficult, but it still takes some effort to mass-produce it.

The craftsmen immediately expressed that they could roll out a few by hand first, and then consider mass production.

Judging from the drawings, this thing is not very difficult. With their ability, they should be able to make it by hand in three to five days.

The only troublesome thing here is the thin spring used to push the flint, other structures can be done by apprentices.

Li Yuechen nodded, letting them rest assured to do it, and at the same time answered some questions.

After finishing all this, it was already dusk, Li Yuechen didn't stay in the engineering institute for dinner, and got into the carriage and went back to the Princess Mansion.

……

When I came back, I happened to catch up with Shangguan Wan'er and the others who were also coming home from get off work.

"His Royal Highness went out in women's clothing for two consecutive days, which is rare." Shangguan Wan'er felt a little surprised.

"Hey, I'm here to keep a low profile."

Li Yuechen came to the table and sat down while talking: "Everyone in the city knows that I like to wear a big red round-neck robe on weekdays. A little change in clothing and hairstyle can reduce the possibility of being recognized."

"That's true, but why is Chen'er so low-key?" Princess Xuancheng said that she didn't quite understand.

"My sister doesn't know something, it's not a good thing to be too famous." Li Yuechen leaned on the back of the chair and said, "Sometimes, it's better to hide it."

The sisters ate dinner while chatting, drank tea and chatted with each other for a while at night, and then went to bed.

……

Five days passed in a blink of an eye.

During this period of time, Li Yuechen went to Lelou almost every day to rehearse their new shows for these new artists.

In fact, there is nothing wrong with the drama, and the cross talk and storytelling are still going well.

The only thing that was a bit troublesome was the opera aspect, which made Li Yuechen feel a little overwhelmed.

Because to be honest, she doesn't know how to sing, she just watched it on TV, and she wasn't very interested in it at first, let alone studied it.

So it is better to say that it is to guide them than to give them an idea, and the rest can only be imagined by themselves.

Of course, this group of artists couldn't make a new gadget from scratch, so they fell into a stalemate for a while.

Fortunately, Li Yuechen didn't urge them, and told them to take their time, don't worry.

After the matter here was settled, he ran to the Engineering Academy.

After five days, the Academy of Engineering has produced three kerosene lighters.

This was done by three craftsmen with apprentices.

One craftsman used copper, the other two used iron and steel respectively.

Li Yuechen picked them up and tried them one by one.

Let me talk about the part of opening the lid first. The sound made of copper is the best, and you can hear the crisp vibrato when opening and closing the lid.

In terms of ignition, there is no difference. They can be ignited stably, and the size of the flame is well controlled.

In fact, she has seen a lot of fancy lighter games in the video before, and each finger is very flexible, which can make the lighter fly up and down in her hand.

It's a pity that Li Yuechen didn't smoke back then, and he didn't know how to play these things.

But it doesn't matter, since this thing is made, someone will definitely think about it in the future.

What I have to do is to mass-produce it as soon as possible. This thing is interesting enough, and its size is not big. It will become a product favored by many foreign businessmen.

Li Yuechen even dared to say that in this day and age, in the eyes of those foreign businessmen, lighters may become a commodity comparable to silk and tea for a period of time.

In addition, now only the Academy of Engineering knows how to make kerosene, and it will continue to make money in the future.

Thinking of this, Li Yuechen couldn't help but think, the richer he is, the richer he is.

After asking them to determine the mass production plan, Li Yuechen returned to the Princess Mansion, and called in the future to discuss the matter of importing.

Although Pei Qingwan is taking care of her property now, the one who is mainly in charge of connecting with foreign businessmen is still here.

After so many years, today's Laicao is different from before. He is full of jewels, and he has gained a lot of weight, just like a big boss.

It's just that he is really old, and his hair is mostly white, but he looks good, with a rosy complexion, and he thinks that the pressure of life is very small.

After entering the princess mansion, Laicao entered the house, and immediately saluted respectfully: "I have seen Your Highness the Princess! I haven't seen Your Highness for many years, I really miss you..."

Li Yuechen picked up the teacup and smiled: "You will miss me? This sounds so fake!"

When he came here to mess with things, he was almost solved by Fulai, so to this day, he is still very afraid of the princess.

"Your Highness, don't be joking, these are all words from the heart of a villain...the truth is sincere!" Laicao was startled, and hastily explained.

"Okay, okay, don't use words indiscriminately if you don't read much!" Li Yuechen put down his teacup and waved his hands, "I called you this time, I want you to go back and tell those foreign merchants to buy some water..."

As he said that, he also took out a current map of the world: "This place is rich in this thing, just dig it out."

The emergence of kerosene means that the demand for oil will increase in the future, so Li Yuechen plans to gather some wool first.

"Wei water? Isn't there a lot in our country? Why does Your Highness pay for it from abroad?" Laicao expressed his puzzlement.

"You can't understand even if I explain it!" Li Yuechen waved his hand, "In short, the price can be as low as possible, and you can buy as much as you can. This item will be in great demand in the future! I will ask the Engineering Institute to build a batch of iron barrels. Used to hold..."

Li Yuechen planned to take advantage of the lack of information and not to exploit domestic oil, but to buy it from foreign countries.

For the people of Dashi Country, the current knowledge of this thing is that it can be used for burning, so it is almost zero cost.

Just give those merchants enough transportation fees, and buy it for 100 years first!

Thank you [Yelongsha] for rewarding 100 starting coins!
