"Alright, let's go to breakfast!" Li Yuanxing carried Wu Cao and did not go to the main house, but walked towards Li Changying's courtyard. He planned to let Qiu Xiang and Yuan Chun sleep a little longer.

Wu Cao suddenly asked, "I said, have you been transformed?" ”

"What nonsense?" Li Yuanxing slapped Wu Cao's ass with his backhand.

"You're amazingly strong, you can get out of bed, and you're in such good spirits, you explain it to me!"

"Lao Sun's internal and external skills are good, which proves that I am a genius!" Li Yuanxing said with a smile.

Wu Cao suddenly smiled stupidly.

"What are you laughing at?" Li Yuanxing asked.

What Wu Cao was thinking just now was, Li Lanshan, aren't you the man who robbed me, I don't know if Li Yuanxing is so strong, can you stand it? However, Li Yuanxing asked, she naturally didn't know how to speak, and immediately changed the topic: "Wait a while and go to the study, I'll show you an interesting one of the rules in the Tang Palace." ”

"Just pick the key points and tell me."

"The point is ......" Wu Cao whispered close to Li Yuanxing's ear: "According to the rules of the palace, the imperial brother has at least fifteen to eighteen days a month, and there are nine people who enter the palace every night to sleep. However, I don't know if it's all nine together, or one of the nine at a time. ”

Li Yuanxing's cheeks twitched: "Let's talk nonsense!" ”

"I found the relevant information, you have the ability to go to the palace to verify."

Seeing that he was about to arrive at Li Changying's courtyard, Li Yuanxing warned with a cold face: "Don't talk nonsense for a while." ”

"Yes, my honorable Highness King Qin!" Wu Cao smiled very happily.

Li Yuanxing went to his small courtyard. When Li Yuanxing was still a hundred steps away, a maid told Li Changying. Li Changying, who was greeting outside, asked with a smile after saluting, "What's the interesting thing, Princess Mingyue is so happy." ”

"Isn't it fun to have strawberries ripe with cream?"

"Really!" Li Changying shouted excitedly, and then quickly counted the date: "No, according to the date of the next planting, there should be two days left!" ”

"There are some early maturation, not unexpected!" Li Yuanxing took over the topic.

Creamy strawberries are naturally modern seeds, but there are not many of them, so they are planted in the flower room. And it was planted by Wu Cao and the seven princesses of Qin, so they were all very concerned.

Li Yuanxing was able to come to Li Changying's courtyard for breakfast. This made Li Changying very happy. At least she thinks it's Li Yuanxing showing favor to her. Because last night was supposed to be her night.

Li Yuanxing gave an order in Qinwangzhuang, it doesn't matter what you eat or how much you eat, but food can't be easily wasted.

So Li Changying's breakfast here is for a concubine with the title of prince. It's too simplistic.

Each person has a boiled egg, a piece of cake, a plate of side dishes, a bowl of white porridge, and a small snack. That's all!

"Your Highness. The concubine wanted a few bars of soap. There are also two bottles of white face cream. Li Changying's voice was not loud, she was pleading. Because of these things, Datang does not have. In particular, the soap is only available in King Qin's secret vault, and even the bathroom is not placed, but it is distributed to everyone, and there is a monthly ration.

Li Yuanxing didn't speak, just grabbed a chopstick and put it in his mouth.

Li Yuanxing is thinking......

Li Changying was afraid that Li Yuanxing would not agree, so he hurriedly explained: "Your Highness, my cousin will get married in two months, and we have been friends since we were young!" After that, Li Changying looked at Li Yuanxing with some nervousness.

Li Yuanxing shook his head with a smile, he just thought about whether Datang should make something like this. Seeing Li Changying's expression, he reached out and gently caressed Li Changying's cheek.

When Li Yuanxing stretched out his hand, Li Changying's body was stiff, and when Li Yuanxing's hand touched the skin on his face, Li Changying felt an indescribable thing gushing out of her heart, in short, it was very comfortable, and she even expected Li Yuanxing to touch her face again.

Wu Cao was just eating, and she wouldn't mention it if she had an idea.

Li Yuanxing is a man, and she will never lose Li Yuanxing's face in front of a third party.

This is the territory where Li Yuanxing is the master.

"You can make these things yourself in the future. Aren't you afraid of being laughed at if you take two dollars for a penny and give it away? If you want to send it, why don't you pull a car! Li Yuanxing said half-jokingly.

"A penny!" Li Changying didn't believe it.

"I can't make a penny, this palace thinks ......" Wu Cao said this, but he was not in a hurry to continue, and drank his porridge slowly, Li Changying kept staring at Wu Cao.

Wu Cao wiped his mouth and continued: "If it is pure natural, hand-refined, and the quality exceeds your synthetic things, it will cost at least four yuan, or even six yuan!" ”

I thought Wu Cao could name what a huge number.

Four pennies!

Soap, a thing that makes women crazy, is only four cents, can you add another zero to this price? Or, directly add two zeros, and the price in Li Changying's heart is definitely higher than four hundred Wen.

"I have already checked the raw materials, and in the medicinal fields of Yaozhou, hundreds of kinds of flowers weighing several tons of each can be harvested. Then there is the oil and ingredients, the oil is easy to do, and there are countless Qinwangzhuang. The ingredients are the most troublesome, but this palace believes that those Taoist priests who have gone crazy can make them in three days! ”

Crazy Taoist priests!

That's right, it's the crazy Taoists, you must know that alchemy is the craziest technique of the Taoists. Li Yuanxing's chemistry, basic chemistry, biochemistry, industrial chemistry, etc., the knowledge of various chemistry made the Taoist priests crazy, because they created many magical things. Like, sour!

The terrible liquid that can destroy all iron tools is not the most terrible thing compared to acid.

"Soap!" Li Yuanxing smiled and looked at Li Changying.

"Your Highness!" Li Changying blushed when Li Yuanxing looked at it.

"The king doesn't care about the soap thing, you can do it." After Li Yuanxing finished talking about the soap, he said to Wu Cao again: "You go to Yaozhou and let them make another steam engine for the train, I read the report on the locomotive last night." We use a multi-rise steam car, and the utilization rate of power is only 4%! ”

Wu Cao understood what Li Yuanxing meant.

There are some things that can't be said in front of Li Changying, but the meaning is clear, and the words can continue.

Historically, the earliest steam engines before the Industrial Revolution had an energy conversion rate of a few cents and less than three percent. That one is the most primitive and simplest steam engine.

Now this is not explicitly stated in the report, but Li Yuanxing used the coal consumption to roughly calculate according to the formula of later generations.

Even if it is wrong, it will not be too wrong, in a word, this steam engine is not a qualified product at all.

Wu Cao also said: "The problem of the process, the sealing is not good enough, and there are air leaks in many places. Moreover, the pressure of the boiler is not enough, the water temperature and air temperature are poor, and the most important thing is that the combustion of coal is too poor. I also know about the coal used in the trains, and many poor people can still pick up a large amount of coal cores and take them back to burn them! ”

"What is the proportion?"

"You can pick up three percent of coal cores!"

Li Yuanxing wanted to say, is it too urgent to have a steam engine now, and when the basic industrial capacity cannot be reached, will this method produce adverse consequences?

Wu Cao saw Li Yuanxing's worries. "Don't worry, you can fill all the gaps, even the pillars!"

"You go to Yaozhou. When you get back, I'll prepare you ice cream! ”

Wu Cao set off after breakfast, and there were three princesses of Qin who followed her, and their goal was not only to see the steam engine, but also the more important soap. It is a soap that gives off a floral fragrance and can make the skin more beautiful and cleanse the body very well.

If it weren't for the fear that Qin Wangzhuang wouldn't even have a hostess, then they would definitely all go to Yaozhou. Even Li Liyuan wants to follow and see, and even wants to know whether this soap workshop will be located in Yaozhou or Chang'an.

Li Yuanxing still has work in the morning, and he still needs to sort out the school textbooks.

Li Liyuan followed Li Yuanxing into the study.

"This morning, we divided the textbooks." Li Yuanxing said as he took out a box and opened the computer and printer at the same time. Li Liyuan's eyes were no longer enough, she couldn't figure out what was here, what were these things for, and when she heard Li Yuanxing's order, she just gave a stupid sigh.

"If I don't teach you how to use these things today, don't worry!"

Li Yuanxing took out the printed haode thing from the box, picked it up and put it on the table: "Each page is three, first divide it into three parts in order, the order is very important, and more importantly, you must also pick out the mistakes in it, or what you think is inappropriate." This is a textbook from 6 to 10 years old! ”

The Three Character Classic is definitely the first lesson of Mengxue.

This is the best Mongolian textbook, but it is not used by six-year-old children, this is used to learn to read and write when they are four to six years old, two years, Li Yuanxing believes that even stupid children can memorize it, and recognize all the words on it, two years, six hundred words, is not very difficult.

"Your Highness, this mathematics doesn't seem to be suitable as the first book for beginners!"

As soon as the fascicle began, Li Liyuan put forward an opinion: "Your Highness, this addition and subtraction formula is excellent, but this number. It took a long time for the concubine to get used to it, did His Highness consider adding a lesson to teach this number first? ”

Li Yuanxing used Arabic numerals, which were familiar to children in the modern era of later generations. But in the Tang Dynasty, there are not many people who really know this Arabic numerals, and it is only the merchants who have had contact with Qinwangzhuang that they slowly began to come into contact with them, and adapted to Arabic numerals, as well as the new bookkeeping method spread by Li Yuanxing.

Li Yuanxing really ignored this problem, and was reminded by Li Liyuan, Li Yuanxing even claimed: "Yes, it makes sense, I will add a few pages immediately, and at the same time I want to explain that in the official counting, it is necessary to use regular Tang Chinese!" ”

The formal Tang language mentioned by Li Yuanxing is: one, two, three, four, and Wu...... (To be continued......)
