Great Tang princess

Chapter 58 The Value of Commodities

Li Yuechen saw the opportunity, and added some goat milk and essential oil.

There is indeed essential oil in this era, but it is not called essential oil, it is called fragrance dew.

And after listening to Xiao He, it seems that it is not obtained by distillation, but by extraction, so there is definitely no way to compare it with future essential oils in terms of purity.

The only thing that is better is that this thing is pure natural, without any chemical additives.

After all, to make soap, you still need some fragrance.

When it comes to fragrance, it has to be said that human beings have been searching for a good taste since ancient times.

Be it past, present or future.

After more than a thousand years in this country, although most of them have perfume as the main product of daily life.

But when it comes to incense, the first thing most people think of is still incense sticks.

What is contained behind this is probably the power of culture. What you taste is not only the taste, but also the artistic conception of the green smoke and fragrance.

Li Yuechen shook his head and came back to his senses. Seeing that the viscous liquid in the porcelain jar was almost gone, he ordered the other eunuchs to come over, put on thick animal leather gloves, and slowly poured the liquid in the jar which had been set aside. in the mold.

Curious, Fulai took two steps forward, and smelled the fragrance of flowers as soon as he got close.

He bent down and asked curiously, "Your Highness, what is this?"

"Don't ask, you'll know when you're done." Li Yuechen waved his hand mysteriously, and asked them to put the assembled molds in the sun for a few days.

Looking at the irregular white lumps inside the mould, Fu Lai tilted his head, and followed Li Yuechen without asking any more questions.

Li Yuechen ordered the maid next to him to watch, and then went back to the palace to study and practice calligraphy.

Shangguan Wan'er and her two older sisters were there, and Fulai lit some incense with a small sachet and hung it in front of the table.

The curling green smoke filled the hall in a short while, floating in the sky above the few people and condensed without dispersing.

After a while, Fulai brought an account book: "Your Highness, this is the recent record of the store's income and expenditure."

"Ah."

Li Yuechen agreed, picked it up and flipped through it while writing and drawing on the desktop with his fingers.

Princess Xuancheng smiled and said: "No wonder Chen'er said that he is good at arithmetic a few days ago, so it was because of the account book?"

"That's right." Li Yuechen smiled.

About 5 minutes later, Li Yuechen nodded and called Fulai: "Okay, your nephew did a good job!"

"Thank you, Your Highness, for your compliment." Fulai got up and left with the account book.

Princess Xuancheng seemed a little surprised: "I didn't expect Chen'er to calculate so quickly, and the calculation of several hundred yuan was completed in a short time."

Only people like you who have never been tortured by high numbers can say this. Can simple addition and subtraction be called difficult?

"What's so difficult about it? It's extremely simple." Li Yuechen said indifferently.

Such a calm tone successfully aroused Princess Xuancheng's curiosity: "Then how did Chen'er calculate just now?"

Li Yuechen thought that she would be free anyway, so let's give her some popular science.

So he wrote down the Arabic numerals directly on the paper, "First of all, with these numbers, any number can be formed very simply..."

Princess Xuancheng is also relatively smart, and she learned it quickly.

So Li Yuechen began to explain to her the concept of addition, subtraction, multiplication and division on the basis of Arabic numerals.

Princess Yiyang and Shangguan Wan'er beside her also listened with great interest.

"The so-called multiplication is the addition of multiple groups of numbers. Like Jiujiu song, seven plus seven times seven is 49; on the contrary, division is to divide the number into multiple groups. For example, 49 is divided into seven groups on average, and each group is It's all seven..."

After explaining the concept, Li Yuechen put the numbers in the account just now into a small multiplication formula, and then got the final number.

"Look, it's very simple, right?" Li Yuechen put down his pen.

"I didn't expect it to be so miraculous!" Princess Xuancheng's eyes lit up, and she exclaimed in disbelief.

Princess Yiyang and Shangguan Wan'er next to her opened their eyes wide open, appreciating the magic of arithmetic at this moment with their hearts.

Princess Xuancheng raised her head: "Are there any other cases?"

Li Yuechen nodded, and began to explain to her many cases in elementary school mathematics.

A few days ago, Princess Xuancheng seemed to think that arithmetic is useless, but after seeing the magic of this aspect with her own eyes today, she immediately fell into it.

Li Yuechen told her for another hour or so, planning to go out and look at his soap.

Princess Xuancheng held her arm: "Wait, then..."

"I don't think it's better than this." Li Yuechen took the paper on the table and began to write, "What I said just now, sister, why don't you try to apply it."

While talking, he wrote down two questions on the paper.

They are "A bottle of canned food sells for 5 yuan, buy 5 bottles and get 1 bottle free, how much do you need to buy 45 bottles?" and "A soap is 16 yuan, buy 3 and get 1 free. several?"

After finishing writing, he pushed the paper in his hand forward, and Li Yuechen tapped on the paper with his fingers.

He grinned and said, "Sister, why don't you see if you can answer these two questions."

After finishing speaking, he turned around and went to the backyard to check the soap, leaving only Shangguan Wan'er and Princess Yiyang looking curiously at Princess Xuancheng who was beginning to think.

Obviously, the two of them are also secretly calculating in their hearts, but judging from their expressions, they are not as deep as Princess Xuancheng.

Princess Xuancheng fell into deep thought and began to calculate on paper.

When Li Yuechen came to the backyard, he saw that the soap in the mold had begun to solidify, it was spotless and white, and even had a faint glow in the sun.

Picking up the mold plate, leaning over your head, closing your eyes and smelling lightly, a faint floral fragrance rushed straight into your brain through your nose.

"Not bad..." Li Yuechen opened his eyes, nodded and said to himself.

Fulai on the side still looked curious, but didn't ask any more questions.

Then Li Yuechen asked them to take the mold plate into the hall and cover it lightly with wooden boards.

Back in the palace, Li Yuechen found that Princess Yiyang and Shangguan Wan'er had already started reading other books, while Princess Xuancheng was still thinking hard about these two questions.

In fact, relying on what Li Yuechen taught him is enough to solve it, but after all, he has just learned it, so the reaction is a bit slow.

In a blink of an eye, three days have passed.

Li Yuechen opened the soap covered by the wooden board to look, found a piece of cloth, and then asked the two eunuchs to turn over the mold plate and buckle it down.

"Clatter..." A dozen pieces of soap fell down and landed in the middle of the stretched fabric.

Li Yuechen took out two pieces and handed them to Fulai and Xiaohe respectively: "You guys use this thing to wash your hands now, the specific usage is..."

After listening to her explanation, the two took the soap and washed their hands.

He took the cloth and wrapped the remaining ten or so pieces and carried them into the main hall.

Just after putting down the soap, Fulai and Xiaohe came back with surprised expressions.

Li Yuechen sat down cross-legged in front of the table, with an inscrutable smile on his face: "How is the effect?"

Fulai's surprised expression remained unchanged: "Your Highness, this thing is really miraculous!"

"Yes." Xiao He also replied, "I still have a scent in my hands..."

As he spoke, he unconsciously put his hands in front of his face and sniffed vigorously.

Seeing her like this, Li Yuechen didn't laugh at her, but just smiled: "The two yuan will be given to you."

Fu Lai and Xiao He looked at each other and saluted respectfully at the same time: "Thank you, Your Highness, for the reward!"

Afterwards, Li Yuechen rewarded the two elder sisters, Shangguan Wan'er and Zheng Shi, respectively.

Anyway, there are only a dozen or so test products in the first batch, and there is no plan to sell them. It is better to let more people try to see if they work well and see the effect.

As for where the parents are, let's wait for a period of time to experiment and see the effect.

So Li Yuechen warned: "Don't let other people know about this thing, I'll see how it works, and then go and dedicate it to my parents!"

Several people expressed their understanding one after another.

……

The next day, in the morning, I still took my two older sisters and Shangguan Wan'er to practice yoga.

Today is the day to go to Liu Rengui's house for inspection, and Li Yuechen went to the master's house to practice in a carriage.

After coming back at noon, just as she sat down to eat, she saw Princess Xuancheng running over excitedly: "Look, Chen'er, I've solved it!"

As he spoke, he handed over the paper in his hand.

Li Yuechen took it over and took a look, and found that the process of concluding the question was written in detail. Although it was a bit long-winded, the answer was indeed very good.

So he smiled and nodded: "Yes, it seems that my sister is very talented in arithmetic."

"Really?" Princess Xuancheng was a little confused, "I just think these are very interesting."

"Why don't you explain something more interesting to my sister this afternoon?"

"Okay!" Princess Xuancheng nodded.

……

For the next period of time, Li Yuechen explained to her about mathematics every afternoon.

Time passed quickly, and it was the end of October in a blink of an eye.

The first batch of soap that Li Yuechen sent out has basically been used up, and the effect...is obvious.

Fulai and Xiaohe have fallen in love with this thing thoroughly, and now they are almost used up, and they dare not ask her for it, thinking about how to get her to give him another piece every day.

It was Princess Yiyang who said that the last soap was almost used up, could I give her another piece of soap.

As soon as these words came out, the others also looked at Li Yuechen eagerly.

Li Yuechen gave them another one piece, and took the remaining three pieces to Anfu Hall.

Li Zhi looks good recently, and he is also in a good mood. When he saw Li Yuechen coming, he asked her to come and talk with him.

Li Yuechen sat directly on the low table next to him, grinning: "Grandpa, my child has researched a new utensil again."

"Oh?" Li Zhi was obviously interested, "Let's hear it."

Li Yuechen didn't hold back, and directly took out a piece of soap and handed it to him: "Grandpa, please take a look, this is it."

"Huh?" Li Zhi took it over and looked at it, then smelled it, "What is this? Is it balm?"

"No, this thing is for washing the body, why don't you wash your hands and try it." Li Yuechen reminded.

Li Zhi nodded, and directly asked Zhang Chengxin to bring a basin of water, and then began to wash his hands in the way Li Yuechen instructed.

Wu Zetian also walked over curiously, wanting to see what it was.

Under Li Yuechen's guidance, Li Zhi's hands were quickly covered with white foam, and then he put his hands into the copper basin with water to wash off the foam.

After drying his hands with a sheep towel, Li Zhi took a closer look at his hands: "Hiss... this feels a little special! And..."

Speaking of this, put your hands in front of your nose and smell it: "Well, there is also a floral fragrance."

Wu Zetian asked Zhang Chengxin to change the water in the basin, and after trying it himself, he nodded happily: "It's really a good thing, and I feel that my hands are much cleaner."

Li Yuechen chuckled: "This soap can not only be used to wash hands, but also to cleanse the body, just be careful not to enter or enter the eyes!"

"Hahaha..." Li Zhi laughed twice, "Not bad! You are indeed my daughter!"

"I want to use this thing to earn money from those ministers, so that parents won't worry about money!" Li Yuechen said.

Li Zhi nodded: "Yes! Good idea!"

This time Wu Zetian didn't say anything, but took a new piece of soap and started to think seriously.

Li Yuechen took out the last piece and handed it to Zhang Chengxin: "Eunuch Zhang, this is for you!"

"Oh, thank you, Your Highness, for the reward!" Zhang Chengxin looked surprised, saluted respectfully, and took it with both hands carefully.

Li Yuechen waved his hand, turned his head and smiled and said, "In the future, my mother will use this thing to wash her body, and there will be a fragrance every day!"

Li Zhi happily picked her up and put his head against her forehead: "Oh, what a daughter!"

Li Yuechen laughed loudly, and started to fight with Li Zhi, Zhang Chengxin gave Wu Zetian a silent salute with a wink, and quietly withdrew.

After arguing with the two for a while, Li Yuechen resigned and left.

Only Li Zhi and Wu Zetian were left in the Hall of Renshou.

Li Zhi lay down on the rocking chair again, grabbed the health ball and rolled it up again: "It's really unexpected, Chen'er gave me a big surprise this time!"

"Yes, once this product comes out, it will definitely be huge profits!" Wu Zetian grabbed the new piece of soap and smiled, "At the beginning, Chen'er said that he would open a shop to solve his majesty's financial difficulties, but now it seems that it can indeed be realized. "

Li Zhi nodded: "I have always believed that Chen'er is a genius in the sky, and he is definitely my blessing in the Tang Dynasty... I am afraid that this thing will really make those aristocratic families spend a lot of money."

"Perhaps we should mention Chen'er and set the price higher," Wu Zetian said with a smile on his lips. "In this way, it will be difficult for them to resell."

"Hahaha... Meiniang who knows me!" Li Zhi laughed loudly, but then shook his head again, "But I think, Chen'er should be very clear about this! Why don't you talk about it after seeing the situation first."

Wu Zetian nodded: "Then follow what Your Majesty said!"

The two were discussing the price issue here, and Li Yuechen was indeed thinking about this issue.

In terms of the cost of this thing, as long as it sells for [-] cents each, it will be profitable.

But the problem is that this is no longer a price that ordinary people can afford. Perhaps mass production using assembly lines can reduce a lot of costs, but Li Yuechen also doesn't want anyone to use his own things to become second-hand dealers.

So...how should I think of a way to ensure the maximum benefit?
