During this period of time, the entire Wang family in Chang'an City was in an uproar because of the matter of Wang Guifei.

Li Chengqian rarely went out during this time, but on the contrary, he stayed in the East Palace more for his big business.

At this time, Guan Lishi was reporting everything about Chang'an City to Li Chengqian.

"His Royal Highness the Prince, now the Wang family is in danger, and many people are in prison. Now they seem to be showing signs of shrinking in Chang'an City, the Cui family, the Zheng family, and the Lu family take the opportunity to fight back and eat some of the industries that belong to the Wang family, and after a while, the Wang family may fall out of the five major families of Chang'an! ”

In fact, there is also a Li family, but this Li family is a royal family, so they can't move, and they don't bother to fight with them.

"Is that so? I can't imagine that a Wang Guifei has this power, so that the Wang family is corrected, this is also to blame them for being too arrogant, relying on a Wang Guifei is lawless, you know, the current world is still the world surnamed Li! They can't be presumptuous! ”

"Yes, His Royal Highness the Prince, there is one more thing ......"

Guan Lux said hesitantly.

"What's the matter, tell me quickly!"

"I'm afraid that the Seventh Prince will ......"

Guan Lux refers to Li Yun, afraid that he will hold a grudge.

After all, Wang Guifei is his mother, and as soon as Wang Guifei enters the cold palace, he will not feel good.

"I'll talk to him about him."

After all, this is a major right and wrong, and if Wang Guifei makes a mistake, she will be punished.

Li Chengqian is helping Wang Guifei, find out early, and give her a chance to mend her ways, otherwise if Li Shimin finds out directly, I'm afraid it won't be as simple as three years in the cold palace, and it may be that he will be killed, which will be miserable.

Li Chengqian had already had an idea to talk to Li Yun, and he was glad that this little kid believed his words.

"Then I'll be relieved."

"Okay, pay more attention to the situation of the Wang family when you have time!"

"Yes!"

After Guan Lux went down, Li Chengqian went to his three acres of land, during this period of time, he asked Yu Chi Baolin, Cheng Chumo, Fang Zhizhi and Du Wei to look at the farmland there, and in his spare time, he would also teach them a little knowledge, in his words, this is called part-time study.

Because he is his own person, he can rest assured, if it is someone else, if the secret of this farmland is known and spread, then he will cry.

But when he passed by the courtyard, he heard the cry of the palace maid.

He immediately stopped.

Among them is also the voice of the eldest grandson empress.

Li Chengqian thought to himself, why did Empress Eldest Sun come to the East Palace today? But if you want to come back, you probably came to find yourself.

But I heard the palace maids saying: "Your Royal Highness, please forgive me for the sin, the slave maid failed to wash the clothes of the four princes." ”

I saw that the palace maid was holding a piece of Li Tai's clothes in her hand, and there were many stains on the bright material.

After Li Chengqian saw it, he suddenly remembered what was going on, the stain must be the juice from the sweet potato vine when Li Tai removed the grass, and this thing can't be washed off with water.

You need to use soap......

Soap......

Li Chengqian suddenly remembered this name in his mind.

The people of Datang use soap to wash their hair and clean it, even the royal family uses this thing, Li Chengqian feels unaccustomed to it, and often can't wash it cleanly, and when it is washed, it still feels very greasy.

Why didn't you think of getting soap in the first place?

So, he quickly searched his mind, and sure enough, there was a memory of soap.

In the Song Dynasty, there was a man named Yang Shiying who wrote a book called "Renzhai Zhiji", in which the specific "soap recipes" were recorded

With this talent, the ability is really Bogu Tongjin!

Therefore, in Li Chengqian's mind, such a recipe appeared: Angelica dahurica, white aconite, white zombie silkworm, white rhizome, pig tooth soaphorn, tribulus terrestris, white silk, grass black, hawthorn, jatamansi, white cloves, rhubarb, weed, crane white, almond, soybean flour, pig fat, light powder, honey monk, camphor, children's tea......

You can also add some spices, and the soap is simply beautiful.

Soap can not only be used for laundry, but also for bathing, which is simply not too cool.

There is an ancient text about its function: the face is as white as snow in ten days, and it is like congealed fat in twenty days.

This wave was really 666 in ancient times.

If this soap is used to promote it, it must be a scarce product!

Thinking of this, Li Chengqian was also interrupted by the sound of conversation.

Empress Eldest Sun held Li Tai's clothes in her hand and said, "That's really a pity for this dress!" ”

Regret could be heard in her tone.

The cost of the princes' clothes is not cheap, and at this time, she must be scolding Li Chengqian in her heart for letting the five princes remove the grass and make good clothes like this.

"Her Royal Highness, slaves and maids should be damned!"

The palace maid actually started to slap her face, but it wasn't her fault.

"Alright, don't blame yourself! You are not to blame for this! If you can't wash it off, there's no way to go back and let them make another one. This kid is really ......."

Li Chengqian knows that Empress Changsun is usually a very frugal person, and sometimes she is reluctant to change into new clothes, and her character is obvious to all.

So it makes sense for her to say this.

"But Her Royal Highness the Queen is ......"

"I have a way! I have a way to wash this garment! ”

Suddenly, Li Chengqian stood up and said.

"Meet the Queen Mother! Queen Mother, why did you come to the East Palace? ”

Then he saluted the eldest grandson queen.

The palace maid also saluted Li Chengqian: "Meet His Royal Highness the Prince!" ”

Empress Eldest Sun explained:

"I happened to pass by the East Palace, and I thought I would come and see how they are studying! What's going on with this Tai'er's clothes? And what is the way you said? ”

When she said this, she was very attentive, but Li Chengqian said: "At this point, I was at fault first, I should have let my younger brothers do a good job of protection, but I let these young ladies be wronged!" ”

When he said this, the palace maids who were doing the laundry were so moved that they were about to cry, and I am afraid that no one understood them better than Li Chengqian.

And Li Chengqian then changed his words and said: "Queen Mother, the child recently looked at the ancient book, which recorded that dozens of raw materials can be used to make a thing, but it can wash the stains on this clothes and make it as beautiful as new!" ”

"Oh? How is that thing made? ”

"Queen Mother, you will do it in my East Palace for a while, and I will let the people prepare the raw materials, and then make them."

Li Chengqian said with a package ticket.

This made Empress Eldest Sun even more curious.

"Good! I'm waiting in this East Palace. I'm looking forward to it! ”

Then he entered the East Palace.

Li Chengqian said to the palace maids: "You all get up, come over and help in a while!" ”

"Yes! His Royal Highness the Prince! ”

Several people were very grateful to Li Chengqian, and hurriedly came over to help.
