Looking at her son who was carried back by a large sedan chair, Princess Yu's tears fell one after another.

After finally waiting for Qianniuwei and the eunuch to leave and asked what happened, Princess Yu cried loudly.

And she cried and scolded: "Your surnamed Liu is not something! It's okay if the emperor punishes my son, but is it necessary to hit the sixty-sixth board? Are you not afraid of hitting someone out?

There is also the Fourth Emperor Brother, is he a heartless person? My son is so miserable, and he still has to take him to the clan mansion to punish him? Is there any brotherhood? Ah?"

King Yu next to him could only laugh and didn't dare to say a word.

What else to talk about?

If you speak no matter what you are right or wrong, you will definitely be scolded.

However, seeing that his son was beaten so hard that he could not even get up, King Yu also complained about his second emperor.

Look at what son you gave birth to!

These children were having some money and even went to the embroidered ward to report it?

I deserve to be beaten so badly!

"Okay, dad, mom, my son did something wrong this time. Don't be sad. I won't do this in the future." Liu Mingqi lay on the bed and said weakly: "Let me rest for a few more days, and I'll summarize the lessons."

"Yeah yeah."

Princess Yu heard this and said, "Son, you should cultivate well and wait until you fully recover. As for the money issue, don't worry, your mother will send it to them in the next two days. But I'm so embarrassed! They are so embarrassed to collect the money!"

"Is our family's money enough?" Liu Mingqi asked.

"Enough! Enough!" King Yu showed his existence at this time. "Didn't the emperor reward three thousand taels of gold now? We don't have much money to use. We have accumulated a lot of savings over the years, and we have taken out a total of 80,000 taels of silver. It will take two or three years to earn it back."

The couple didn't ask why Liu Mingqi had to bear so much.

Since Liu Mingqi escaped from the river, the biggest expectation of her son is to be safe and nothing else matters.

Although they spoke lightly, Liu Mingqi also understood that the foundation at home was not as thick as they said.

But Princess Yu is very smart. Her words meant to directly exchange compensation for silver instead of gold, which reduced the losses.

If you take gold to a money shop outside to exchange it, you can get a one-to-one three exchange rate. One tael of gold can be exchanged for one tael of silver. In this way, you can get more than 6,000 taels of gold and eighty thousand taels of silver.

Then they will get 80,000 taels of silver to the Prince's Mansion. Do they still dare to refuse?

This is how the official exchanges one by one. I don’t have gold, so I can only use silver to compensate. Can’t it?

The emperor will not blame me for this!

But no matter what, more than 6,000 taels of gold is also 80,000 taels of silver. For Prince Yu's Mansion, it is equivalent to the entire income of not eating or drinking a year.

There are only three core figures in the family, but there are more than 200 servants and servants in the family, as well as their families.

He has to be responsible for the food, drinking, defecation and urination of so many people, and the various marriages and funerals in the scene, Prince Yu and Princess Yu are not stingy, and the prince's double salary will not be left.

The business at home is not big.

There are only five restaurants around the capital, and the scale can only be considered small and medium-sized, and the income of a few thousand taels is not much.

That is, the "prince-in-law double salary" that Liu Mingqi was named the prince, and the rewards on the emperor's festival day were saved every year, and then used for various emergency backups, as well as the book for Liu Mingqi to save his wife.

Now that he has lost so much money, it is equivalent to not making any money in a year, and the expenses are still the same, which naturally makes Prince Yu's mansion a little short of money.

...

When his parents left, Liu Mingqi asked Dazhu to call Tian Rong, the housekeeper, to come.

Today's Dazhu was not caught and beaten by the embroidered sibling guard like Chi San yesterday.

Because today I was going to beat a prince and a family member, it doesn't matter if Liu Mingqi and the others attacked, it can only be considered internal conflicts.

But if it were these servants who helped fight, no matter how generous Jing and Emperor were, Dazhu and the others would have to be interrupted and be exiled to the frontier.

So they all stood by and watched, and then waited until their young master and lady were arrested before going to their home to report the news.

In fact, before King Li and King Su entered the palace, many royal families had already come to ask for the emperor, including King Yu and King Yi, but Jing and Emperor did not let them in.

Tian Rong arrived quickly.

Tian Rong, who is already forty years old, gave birth to a son at Princess Yu's family. He came to Princess Yu's house when he was dowrying. It has been almost 20 years now.

When he was named Prince and moved out of the palace, except for some guards and slaves given by his father, Prince Yu did not have any team of his own. It was entirely up to Princess Yu to bring a group of people over, so that the family could have cohesion.

In this era, it is very important for a family to have children.

Their fate is already tied to the master, and they are in a state of prosperity and loss, so they have always considered it for the master, and most of them will not be scattered.

"Your Highness, are you looking for me?" As he said, he looked at Liu Mingqi's appearance and sighed without hesitation, "This... is too strict!"

Tian Rong dared not say bad things about the emperor, so he could only express his sympathy in this way.

Liu Mingqi was not pretentious and asked directly: "Lao Tian, ​​has the first batch of soap I made last month not yet formed?"

"I'm going to tell you these two days." Tian Rong retracted his mind and replied, "I had already pinched it with my hands five days ago without any trace. I squeezed it again yesterday, and it didn't show any trace with a little force, and it looked very hard. The first batch should have been done."

"Go and get a piece of water, and then bring a basin of water." Liu Mingqi ordered.

"OK."

Tian Rong hurried out and walked in with a basin of water for a while. After putting it on the ground, he took out a piece of earthy yellow solid half the size of a palm from his pocket.

Liu Mingqi took it and pinched it with her hands. The hardness was pretty good and the weight was about half a pound per piece.

When I took it to my nose, I immediately frowned.

As expected, the raw material technology is not up to standard, which will lead to a far difference from modern finished products!

At least from the point of view of this smell, it looks fishy.

As a doctoral student in physics and chemistry, it is quite embarrassing to create such soap even if you don’t have any experimental conditions.

But who said that the pigs in this world have never been cut, and the pork emits a fishy smell. Even the refined lard cannot completely eliminate the smell?

The same is true for lamb oil, with fishy smell even worse than lard, and the overall price and cost are more expensive than lard.

butter……

Well, in this era, killing cattle and making oil for soap, I'm afraid Lian Jing and Emperor will kick Liu Mingqi directly into the clan's mansion and be confined.

In addition, I rely too much on various modern raw materials.

Modern reaction of calcium hydroxide and sodium carbonate can obtain calcium carbonate precipitation and caustic soda solution. The caustic soda solution is then mixed with lard to obtain the so-called handmade soap sold on the market.

Well, to be more common, quicklime plus soda ash can precipitate caustic soda solution.

There are two modern labs with raw materials, and they are sold everywhere outside.

But this Dakang Dynasty could not be found for a while.

It’s easy to say about quicklime, but it’s difficult to find soda ash.

In the Ming and Qing dynasties in the previous life, a large amount of alkaline earth could be found by digging directly from the grassland. After purification, you can get soda ash - because the processing area is in Zhangjiakou and Gufengkou, it is also called moustalk.

In no way, the boy could only use wood ash to extract soda ash.

There are a lot of impurities in wood ash, and it takes a lot of effort to completely remove it. However, in order to conceal the effect of wood ash, Liu Mingqi still did the color precipitation and attachment process, making the soap like modern soap yellow, without any gray-black luster of wood ash.

He raised his head and Liu Mingqi handed the soap to Dazhu, "After wet his hands, apply it on his hands, then rub it for a longer time, then wash his hands and take a look!"

Dazhu grinned without realizing it, "Your Highness, is this pancreatic? I can use it once in a month if I take a bath."

While speaking, he still honestly followed Liu Mingqi's method.

Things like pancreas are actually ancient soap. They were made of pig pancreas and grind into paste with fat removed and grind them into a paste, then added wood ash and melted lard. When they solidify, they can wash oily pancreas.

But because the production process is too complicated and there are so many pig pancreas, it is usually only rich and nobles who can use it.

Princess Yu is already generous to be able to use Panzi once a month for the servants of Dazhu.

Normally, poor people should use some semi-solidified liquid made of soap beans to scrub their bodies, or soak them directly in water with wood ash and then scrub their bodies.

These two things will definitely leave a lot of residue, which is not very comfortable to wash and the stain removal effect is very average.

Pancreatic sap is much better, but its smell is not very good, and there is still a big gap in the decontamination effect compared to regular soap.

Even in 2020, no matter what other cleaning products were boasting about, just in terms of the decontamination effect, nothing can compare to soap.

The main reason why soap has good decontamination effect is that part of it is polar carboxylic groups that are easy to soluble in water, hydrophilic and repel oil-repellent, so it is called hydrophilic group; the other part is non-polar hydrocarbon group that is insoluble in water, so it is soluble in oil, and oil-repellent, so it is called hydrophilic group.

When washing hands or clothes, the hydrophobic foundation will be combined with oil and dirt, while the hydrophilic foundation will be integrated with water to tightly wrap the dirt. When repeated friction occurs, foam will form, bringing the dirt into the water.

This is all the principles.

But there is also one thing that people often say that if you wash soap too much, it is because there are many caustic soda ingredients in the soap. If you use too much, it will naturally damage the skin and mucous membranes.

But that was also a matter of the industrial age. Now, the soap made by Liu Mingqi is much worse than the one in the industrial age, and the effect is not as domineering as it is.

"Hey, Your Highness, why has the water become so dirty?" Dazhu is an honest man. When cleaning, he was shocked to see the water becoming dirty instantly.

When he took out his hand, he was even more shocked: "Wow, is this my hand? Why is it so white!?"

Tian Rong next to him kept staring at him. Seeing this, he grabbed his hand without saying a word and picked it up and compared it with his own hand.

As the steward of Prince Yu's mansion, Tian Rong lived a good life, so his family also had pancreas, which could be used every once in a while.

But compared with the hands of the two, Tian Rong's hands completely seemed like an old farmer, and he was so embarrassed to see.

...

Note: After searching for the information, unless it is a modern industrial production, it will take more than a month to produce handmade soap, or even two or three months.

Therefore, it does not exist to come up with a way to make soap tomorrow, and all you get is a piece of paste.

In addition, our country should have had a simple version of soap since the Eastern Han Dynasty, which was called bath beans at that time, and later became popular in the Wei and Jin Dynasties. In the strange book "Jin x Plum" of the Ming Dynasty, Ximen Daguanren mentioned that he used "jasmine soap". Of course, it is different from the modern ones.
