Great Tang princess

After chatting with them in the Engineering Academy all afternoon, Li Yuechen turned and left.

After walking out of the gate of the Engineering Academy and getting into the carriage, Xiaodong was still staring at Li Yuechen with burning eyes.

"Anything to say?" Li Yuechen asked.

Xiaodong shook his head: "I'm just a little surprised, I didn't expect His Highness to invent such a miraculous thing."

To this, Li Yuechen just smiled and did not answer.

But I thought in my heart that after more than 1000 years, these are just children's toys.

But for people of this era, it is indeed a very magical thing, although it still cannot change the fact that it is a toy in essence.

After returning to the Princess Mansion, the sky had already darkened.

Li Yuechen sat down to eat with Shangguan Wan'er and others who came back from get off work.

Sister-in-law Pei Qingwan chatted about the recent business, but Li Yuechen didn't pay much attention.

Anyway, it's just a sentence, make a lot of money, and your assets will almost double.

Don't underestimate these small oil lamps and lighters. For this era, they are almost equivalent to epoch-making products.

With the spread of the news, it has already started to be sold to Chang'an, and some nobles who are in other places have gradually received the news and sent someone to ask.

But at the moment, outsiders can't afford it, and the survival of the next month has already been determined by foreign businessmen, most of whom are from the Great Food Kingdom.

The Japanese envoy Awata Masato also came to ask Pei Qingwan to keep some for him, thinking that when he bought some, he would take it back and sell it to others.

But he is still busy with exams now, and he won't be free in a few years, so Pei Qingwan said that he will definitely give him some when he returns.

Although the business was booming, Li Yuechen didn't feel too excited.

Money is just a number to her now, and it is useless for people in the royal family to ask for money.

Of course, maybe she's the only one who thinks this way, but not everyone else.

After all, I encountered such a problem in class the next day.

……

In the classroom, Li Longji was raising his own questions to Li Yuechen who was sitting on the desk.

"My aunt's business is so profitable, why don't you think of a way to expand production?"

Today's class is an internal class of the royal family that is only once a week, and it is not on the normal school schedule.

Li Yuechen asked back: "What do you think is the use of asking for money?"

"Naturally, you can buy all kinds of utensils you like, and you can also give them rewards, and..." Li Longji began to count slowly.

The others also nodded, expressing their agreement. Since the business is good, shouldn't they take the opportunity to expand production.

However, Li Yuechen shook his head: "You guys, you still haven't changed your thinking."

"What do you mean?" Li Longji asked.

"We are the royal family, and the royal family has the responsibility of the royal family. For us, money should not be the goal we pursue. In other words, we should consider it from the perspective of the entire country when we earn money." Li Yuechen explained slowly , "Otherwise, you will be like Emperor Wen of the Sui Dynasty."

Li Chongrun raised his hand and asked, "Auntie is talking about the Yicang set up by Emperor Wen of the Sui Dynasty?"

"That's right!" Li Yuechen nodded slightly, "Speaking of which, although the Sui Dynasty ended in the hands of Emperor Sui Yang, this hidden danger was actually planted during the time of Emperor Wen of Sui."

"Is there anything wrong with setting up righteous warehouses and stockpiling grain?" Li Xianhui asked, "And according to records, Emperor Wen of the Sui Dynasty was always frugal, and he sewed and mended his clothes. Didn't my aunt say that being frugal is a good thing?"

Li Yuechen picked up his teacup and took a sip: "Frugality is a good thing, but you have to know that Emperor Wen of the Sui Dynasty wasn't frugal, he was picky!"

"The clothes I wear are sewed and mended, but there are too many silks and satins in the warehouse, and they are even eaten by mice... Thrift is not such a way."

"As for the Yicang, at the beginning he was talking about asking the people to hand in grain to prepare for the disaster year. But when the famine really broke out, he didn't open the warehouse to release grain... The credibility of the court is gone!"

"In fact, most of the emperors since ancient times have this problem. As an emperor, they only want the interests of their own family. Rather than saying that they are emperors, it is better to say that they are a large local rich man. Such a person becomes an emperor. But it is still the thinking of landowners, then this country is doomed to not last long! So Sui Dynasty II died!"

Li Longfan put forward his own opinion: "But aunt, shouldn't we pay attention to me, Mrs. Li?"

"For the leaders of the country, private interests must never be put first! Especially the emperor! As an emperor, since he has the highest power, he must be responsible for the people of the country! Therefore, the emperor must be responsible for the majority Act in the interest of man!"

With that said, Li Yuechen jumped down from the podium: "Therefore, the future royal family must change, and can no longer run the country in the same way as before, like a local rich man."

Li Chongfu, the youngest, was a little confused: "After the change, can the country last for a long time?"

"It can only be said that there is a long-term foundation, and the rest depends on how to manage it." Li Yuechen replied, "Take Sui Yangdi as an example, if he is not so happy, maybe he can last for decades. "

Li Lin, who was sitting in the back, asked her own question: "Isn't this... because of Yang Xuangan's rebellion?"

"Then why did he want to rebel?" Li Yuechen asked back, and then said, "Actually, the country is ruined and the family is destroyed. It cannot be said that the minister is not responsible at all, but it cannot be entirely blamed on the minister."

Li Chengqi asked: "But what if the king is not the king of the subjugated country, and all the ministers are the subjugated ministers?"

However, Li Yuechen smiled slightly and said: "If the ruler is a wise ruler, even if the court is full of treacherous officials, the country can still operate normally."

"As we all know, Li Jing, Fang Xuanling, and Du Ruhui are all heroes of our Tang Dynasty. But in fact, if we really want to count forward, these people are all remnants of the previous dynasty. Why is this so?"

"That's because Taizong has the wisdom of people, and he is more capable of cleaning up the mess in the early days of the founding of the Tang Dynasty. The same will be true for you in the future. In this regard, remember to go back and read "Emperor Fan"."

"Okay, this is the end of today's class. After class, everyone will write a paper for me about how the Yang family and his son conquered the country." Li Yuechen waved his hand, announcing the dismissal of the get out of class.

……

In the blink of an eye, it is the end of March, and the weather has become much hotter.

On the way into the palace, Li Yuechen looked at the sunlight shining through the curtains into the carriage, and thought in his heart, according to the Gregorian calendar, it should be May already.

When I came to the Temple of Immortals, I saw that Wu Zetian had changed out of her usual complicated clothes and put on a cool cheongsam.

No, it should be said, princess gown.

"It's really strange that A Niang would wear the clothes invented by the boy." Li Yuechen said with a smile.

Wu Zetian gave her a white look: "I have to say, this kind of clothing is really cool, although it is indeed a bit offensive."

"Don't worry, Ma'am, it may not be like this in 100 years." Li Yuechen sat beside him and asked Shangguan Wan'er to help him pour a cup of tea.

"I heard that you have researched something that transmits sound for thousands of miles?" Wu Zetian asked.

"It's not that exaggerated, it's only two or three feet." Li Yuechen smiled, "Thousands of miles, it would be great if it can be done within 100 years."

Shangguan Wan'er on the side couldn't help asking: "How difficult is it so difficult? Even His Highness can't do it?"

"I told you a long time ago, I'm not a god..." Li Yuechen lay sideways on the seat, "If you can do it, then skip the telegram and do it directly."

"Speaking of this telegram..." Wu Zetian raised his head, "It seems that the project is about to be completed, right?"

"Ok!"

Li Yuechen nodded, and she has been paying attention to this issue recently: "I think it will be completed by the end of May at the latest, and the parts of the generator have also been finished, and it is almost time to consider assembly."

In fact, the parts for the generator had already been made from the moment the telegraph project confirmed it, and now it was time to install it.

It's just a hydroelectric generator, and it would be good to put it directly on the edge of Luoshui, so that the inner guards can take care of it when they patrol.

The size is also measured and will not affect the boats coming and going on the water.

"Well, this matter is worth looking forward to." Wu Zetian nodded.

Li Yuechen couldn't help but smile, and the telegram would indeed increase the administrative efficiency several times.

At this time, Zhang Chengxin suddenly walked in: "Saint, Your Highness, there is a hang glider landing."

"Well, if there is a letter in a while, just send it directly!" Wu Zetian promised.

Not long after, Zhang Chengxin came back again, holding a letter in his hand, and obediently handed it to Wu Zetian.

She took it over and opened it for a look, then frowned: "You girl, why do you send letters in such a format now?"

The army was greatly influenced by Li Yuechen, and now letters were written horizontally from left to right, which made Wu Zetian very uncomfortable.

The most important thing is that education in the military is different from that of the outside world, so letters are written in vernacular.

Scholars from the outside world generally use classical Chinese when writing letters, which is the formal written language.

"Of course it's for convenience..." Li Yuechen took the letter paper while stuffing snacks into his mouth, "Let's take a look, my son."

The content of the letter is very simple, that is to say, the second airship has been completed and Li Yuechen should give instructions.

The second airship was bigger than the first one, and the loading capacity was naturally increased a lot.

Li Yuechen thought that the main thing was to transport grain. Now that the land reclamation on the northern border has not been completed, there is no way to grow enough grain, so it is necessary to adjust the grain in the north.

Of course, the transportation of food does not need to be carried all year round, so this airship can also be used to survey the terrain of the country and improve the map.

The more precise the map, the greater the help to the military, so this work can also be put on the agenda.

The most important thing is that this airship can carry more people, so if there is a war in the future, it can be used as a means of transportation for soldiers when necessary, allowing combat troops to reach the battlefield quickly.

Li Yuechen wrote back his thoughts, and told them by the way, remember to paint the second airship, if possible, it is best to paint it with a shark pattern.

When I was playing Red Police when I was young, I thought it was really cool. Now that I have the opportunity to realize it, of course I have to try it.

Anyway, there are no anti-aircraft missiles these days, so there is no need to consider sky camouflage and the like.

In this day and age, when the enemy sees the airship, it means that they have no intention of hiding it.

So instead of thinking about sky camouflage, it's better to paint it directly to make it more conspicuous and stylish.

After writing the reply, Li Yuechen handed it to Zhang Chengxin: "Let the soldier rest and send it back. By the way, bring a can later."

"Yes!" Zhang Chengxin agreed, turned and left.

Wu Zetian raised his eyebrows: "It's not even April yet, so you want to eat canned food?"

"Eat it if you want it, no matter when it is." Li Yuechen got down again, "May I eat it together?"

"Forget it, Liu Shenwei said, don't eat too much sweets." Wu Zetian shook his head, picked up the teacup and drank tea.

Shangguan Wan'er smiled and said: "A can is not small, His Majesty can't finish it every time."

"That's it..." Li Yuechen nodded, "Why don't you make some sweets for Auntie?"

"If it's the lollipop, forget it." Wu Zetian said with a smile, "I've held it in my mouth for a long time, and my throat is dry."

Li Yuechen made lollipops when he was a child, but his mother didn't like them very much, and now only the third brother Li Xian in the palace occasionally eats one.

Shangguan Wan'er asked: "Will Your Highness make other sweets?"

"There are quite a few things that can be done," Li Yuechen turned over on the ground, and stretched out his body in large characters, "but in this era...huh?"

Lying on the ground, Li Yuechen happened to be able to see the clouds in the sky, and suddenly thought of a childhood memory - cotton candy.

Back then, I could occasionally see someone pushing a [-] bicycle for sale on the street, but it was rare to see it after elementary school.

The key is that this thing is very simple to make, and at the level of today's engineering institute, it is not difficult at all.

"Your Highness?" Shangguan Wan'er saw her in a daze, and called out cautiously.

"I'm going out to study a small object, and I'll show it to my mother in a few days." After speaking, he ran away in a hurry.

Wu Zetian at the back shook his head: "This girl, I still think about it."

"This is Your Highness." Shangguan Wan'er smiled from the side.

Wu Zetian thinks about it too, but a person who has hardly changed since childhood is relatively rare.

……

After Li Yuechen came out of the palace, he came to the engineering institute on horseback. While explaining, he drew pictures and asked them to make a cotton candy machine.

This thing has a simple structure and is not complicated at all. After seeing it, the craftsmen patted their chests and said that it could be done in at most three days.

She doesn't need to worry about the rest, just wait with peace of mind.

But at this time, Li Yuechen suddenly thought, since he decided to start maritime trade in the future, should he take the opportunity to plant more sugar cane in the south and develop sugar production technology?
Now whether it is abroad or at home, the sugar that is made is red, but Li Yuechen knows that the yellow mud can be turned into white sugar.

If this kind of thing is used as an export commodity, it should be very popular, right?

No, it's not just as simple as being popular, it should even be able to be used as hard currency in some places.

The more Li Yuechen thought about it, the more he felt it was possible, but it would be better to do a small experiment first, so he ran back to the Princess Mansion in a hurry.

Called a few eunuchs and court ladies to the kitchen of the princess mansion and started the experiment.
