Datang first village

"Okay, let's go to breakfast together!" Li Yuanxing carried Wu Zhao on his shoulders, and instead of going to the main house, he walked to Li Changying's courtyard.He planned to let Qiuxiang and Yuanchun sleep a little longer.

Wu Zhao suddenly asked: "I said, have you been transformed?"

"What nonsense are you talking about?" Li Yuanxing slapped Wu Zhao's ass with his backhand.

"You are amazingly strong, you can get up, and you are so energetic, explain it to me!"

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

Wu Zhao suddenly smiled foolishly.

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

What Wu Zhao thought just now was, Li Lanshan, you stole my man. I don't know if Li Yuanxing is so strong, can you bear it?But when Li Yuanxing asked, she naturally wouldn't say it, and immediately changed the subject: "Go to the study later, and I will show you an interesting rule in the Tang Palace."

"Pick the key points and just tell me."

"The point is..." Wu Zhao whispered close to Li Yuanxing's ear: "According to the rules in the palace, the emperor has at least fifteen to eighteen days a month, and nine people go to the palace to serve each night. However, what I don't quite know is whether it's the nine together, or one of the nine at a time."

Li Yuanxing's face twitched: "Nonsense!"

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

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

"Yes, my honorable King Qin!" Wu Zhao smiled happily.

Li Yuanxing went to his small courtyard, and when Li Yuanxing was still a hundred steps away, a maid told Li Changying.Li Changying, who was welcoming her outside, saluted and asked with a smile, "What's so interesting, Princess Mingyue is so happy."

“Wouldn’t it be nice to have creamy strawberries when they’re ripe?”

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

"It's no surprise that some of them matured earlier!" Li Yuanxing took over the topic.

Cream strawberries are naturally modern seeds, but they are not in large numbers, so they are planted in the greenhouse.Moreover, it was planted by Wu Zhao 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, which made Li Changying very happy.At least she thought it was Li Yuanxing showing his favor to her, because last night was originally her night.

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

So Li Changying's breakfast here is too simple for a concubine with the rank of a prince.

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

"Your Highness, I want a few pieces of soap and two bottles of white facial cream." Li Changying's voice was not loud, she was asking.Because these things are not available in the Tang Dynasty, especially the soap, which is only available in King Qin's secret treasury, and even the bathroom is not placed, it is just distributed to everyone, and there is a monthly quota.

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

Li Yuanxing was thinking...

Li Changying was afraid that Li Yuanxing would not agree, so he quickly 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 nervously.

Li Yuanxing shook his head with a smile. He just thought about whether Datang should make some of these things.You will see Li Changying's expression, reaching out and gently caressing Li Changying's cheek.

When Li Yuanxing stretched out his hand, Li Changying's body was stiff. When Li Yuanxing's hand touched the skin on his face, Li Changying felt something indescribable surge out of his heart. Anyway, it was very comfortable. She even expected Li Yuanxing to touch it again own face.

Wu Zhao was just eating, and she would not mention her thoughts.

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

This is where Li Yuanxing is in charge.

"You guys can make these things by yourself in the future. Don't you be afraid of being laughed at if you give away two yuan for something that costs a penny? If you want to give it away, you have to pull a cart!" Li Yuanxing said half-jokingly.

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

"I can't make a penny, I think..." Wu Zhao was not in a hurry to speak, and Li Changying was staring at Wu Zhao as he drank his porridge slowly.

Wu Zhao wiped his mouth and continued, "If it's pure natural, handcrafted, and better than your synthetic products, it will cost at least four renminbi, or even six renminbi!"

I thought what a huge number Wu Zhao could say.

Four pennies!

Soap, which drives women crazy, only costs four pennies. Can you add zero to this price?Or, just add two zeros, and the price in Li Changying's heart is definitely higher than four hundred coins.

"I've already checked the raw materials. In Yaozhou's medicinal fields, hundreds of kinds of flowers can be picked, each weighing several tons. Then comes the oil and ingredients. The oil is easy to handle. There are countless flowers in Qinwangzhuang. The ingredients are the most troublesome, but I believe that those Taoist priests who have gone crazy can make it in three days!"

Crazy priests!

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

A terrible liquid that can destroy iron. Compared with acid, gunpowder is not the most terrible thing.

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

"Your Highness!" Li Changying blushed at the sight of Li Yuanxing.

"I don't care about the soap, you can figure it out." After Li Yuanxing finished talking about the soap, he said to Wu Zhao: "Go to Yaozhou and let them make another steam engine for trains. I read about it last night. The report of the locomotive. We use a multi-expansion steam car, and the power utilization rate is only [-]%!"

Wu Zhao understood what Li Yuanxing meant.

Some things cannot be said in front of Li Changying, but if the meaning is clear, the words can continue.

Historically, the earliest steam engine before the Industrial Revolution had an energy conversion rate of just a few percent, less than [-]%.That kind is the most primitive and simplest steam engine.

Now, the report didn't say it clearly, but Li Yuanxing roughly calculated it using coal consumption according to the formula of later generations.

Even if it makes a mistake, it won't be too outrageous. In a word, this steam engine is not a qualified product at all.

Wu Zhao also said: "Problems in the process, the sealing is not good enough, and there are air leaks in many places. Moreover, the boiler is not pressurized 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 that the train uses Many poor people can still pick up a large number of coal cores and take them back to continue burning!"

"What is the ratio?"

"You can pick up [-]% of coal cores!"

Li Yuanxing would like to ask whether it is too urgent to have a steam engine now, and whether this method will have adverse consequences when the basic industrial capacity cannot be reached.

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

"Go to Yaozhou. When you come back, I will prepare ice cream for you!"

Wu Zhao set off after breakfast, and there were actually three princesses of Qin who followed her. Their goal was not only to see the steam engine, but also the more important soap.A soap that exudes a floral fragrance and makes the skin more beautiful, and cleanses the body very well.

If it wasn't for fear that Qinwangzhuang would not even have a hostess, then they would all go to Yaozhou.Even Li Liyuan wanted to go and have a look, and even more wanted to know whether the soap workshop would be located in Yaozhou or in 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, let's distribute the textbooks." Li Yuanxing said as he moved out a box and turned on the computer and printer at the same time.Li Liyuan's eyesight was no longer enough, she couldn't figure out what was there, what were these things for, and when she heard Li Yuanxing's order, she just gave a silly acknowledgment.

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

Li Yuanxing took out the printed things from the box, picked them up and put them on the table: "Each page is three sheets, first divide them into three parts in order. The order is very important, and more importantly, we must also pick out the mistakes. Or what you think is inappropriate. This is a textbook from six to ten years old!"

The Three Character Classic must be the first lesson of elementary school.

This is the best teaching material for elementary school, but it is not for six-year-old children. It is used for early learning and recognition when they are four to six years old. In two years, Li Yuanxing believes that no matter how stupid a child is, they can memorize it and recognize it clearly. All the words above, two years, six hundred words, not very difficult.

"Your Highness, it seems that this mathematics is not suitable as the first book for beginners!"

As soon as the volume was started, Li Liyuan put forward his opinion: "Your Highness, this formula of addition and subtraction is excellent, but this number took me a long time to get used to. Is your Highness considering adding one to teach this number lesson first?" Woolen cloth?"

Li Yuanxing used Arabic numerals, which are familiar to children in the modern age of later generations.But in the Tang Dynasty, there are not many people who really know the Arabic numerals. Only the merchants who have had contact with Qin Wangzhuang slowly began to contact and adapt to Arabic numerals and the new bookkeeping spread by Li Yuanxing. Law.

Li Yuanxing really ignored this issue. When reminded by Li Liyuan, Li Yuanxing even claimed: "Yes, it is very reasonable. I will add a few pages immediately. At the same time, I must also explain that in the official counting, the regular Tang Dynasty must be used. arts!"

The formal Tang prose mentioned by Li Yuanxing is: one, two, three, four, five... (to be continued.)
