The so-called essential oil is actually a general term for volatile fragrance-containing substances processed and extracted from spice plants or fragrance-secreting animals.

And what Cheng Chubi had to do was not to dig out the eyes of the musk deer, but just to wear a small white coat very reservedly and stand in front of the steam distillation vessel.

With his hands in his small pockets, he quietly admired the dogs...... Phew, peppermint is slowly releasing their volatile fragrances......

Since the heating must be less than 100 degrees, the steam distillation method takes a lot of time, but Cheng Chubi only knows this method.

There is a way, which is far better than no way, time passes slowly, and Cheng Chubi rushes out from time to time to see the progress of the two brothers' surgery.

Then he had to go back and squat to guard his essential oil extraction, and after waiting patiently, Uncle Ping had already procured star anise, cinnamon, and fennel.

In almost an hour, nearly twenty catties of mint fresh leaves extracted only one or two more mint essential oils.

Cheng Chubi carefully put the more than one or two peppermint essential oil into the small dark glass bottle in his hand and placed it under his nose.

There is no need to take a deep breath, the strong mint fragrance can't help but lift people's spirits.

After Cheng Chubi quickly plugged the bottle tightly, he began to clean the utensils and prepare for the next essential oil extract of rosemary.

After glancing at the sky, the next pot of rosemary extraction project was still waiting for dinner before continuing.

Under the light, Cheng Chubi stretched out with a tired face,

At this moment, Cheng Fa and Cheng Da, who were also busy with Cheng Chubi until late at night, went to the ice kiln to get the soap that had been made.

Each of the three of them held a mold and tapped it carefully, so that the soap inside the mold would fall off without being damaged.

Today, a total of five molds of soap were made, one was a rosemary type, one was a mint type, and two pieces of each.

Both soaps are half milked and half non-milked, and both are experimental products.

The other three boards of soap are much less, after all, this is a small tool that Cheng Chubi used to take revenge on the housekeeper Uncle Fu and the housekeeper Uncle Ping.

So they only made two pieces of the same, and they really don't want to be ashamed of the smell of braised pork, so it's a big deal to make more for them next time.

Cheng Chubi picked up the rosemary and mint soap and sniffed the smell carefully.

Not to mention, both of these soaps do have their own unique fragrances, but the soaps mixed with a certain amount of goat's milk taste more mellow.

As for the other three kinds of soap, Cheng Chubi only smelled it once, and he almost knelt down, especially the octagonal soap, which smelled very strong.

made Cheng Chubi think that when he was cooking braised pork, he added more star anise ingredients, and it would exude such a taste.

As for fennel and cinnamon, they are also on a par with star anise soap, which really subverts Cheng Chubi's aesthetics for the fragrance of daily chemical products.

"What a strange taste, Third Prince, who dares to use these things? The villain thinks those two are more pleasant to smell."

It seems that Cheng Fa, who is also relatively normal for fragrance aesthetics, sat up straight with a little dark face, trying to stay away from the three strange-smelling soaps.

Cheng Da, on the other hand, picked up the cinnamon-flavored soap and took a deep breath. "I think this tastes pretty good, it's quite gluttonous."

Cheng Chubi's face darkened and looked at Cheng Da, who felt almost the same as Uncle Fu's fragrance, worthy of being born to Uncle Fu, although Cheng Fa was too, but he didn't like either.

Cheng Chubi hurriedly wrapped these three kinds of soap and oiled paper and put them in a lacquered box with chrysanthemum patterns.

"Don't worry, tomorrow I will give it to those who like this taste, as for you, if you want to follow me, you are not allowed to use these three flavors."

"Don't worry, San Gongzi, I just think it's okay, in fact, I prefer this one called mint scent, it smells very refreshing."

Cheng Da hurriedly smiled and affirmed that his aesthetics were actually relatively normal.

Of course, Cheng Chubi didn't have a reason to give the test samples to these two rough old men, and he had just given these two bars of soap before, but they hadn't used them up yet.

#####

In the early morning, the sky was clear, and the temperature was relatively cool, and Uncle Fu, the housekeeper, took the four lacquered wooden boxes handed over by Cheng Chubi.

Cheng Chubi looked at Uncle Fu, the housekeeper in front of him, suspiciously, and saw that he couldn't wait to open one of the boxes.

took out the cinnamon-flavored soap inside, and then put it on the lower side of his nose, and took a deep breath with a drunken face, which deeply made Cheng Chubi bow down.

"Well, this smells so good, hey, this octagonal smell is too, thank you so much for the gift of the third son."

Uncle Fu, the housekeeper, smells of anise in one hand and cinnamon in the other, and smells extraordinarily intoxicated.

Cheng Chubi thinks that the housekeeper Uncle Fu has a peculiarity? Neither is it right...... After all, star anise and cinnamon are also spices.

Seeing the housekeeper Uncle Fu leave with the two kinds of soap, Cheng Chubi raised a forty-five degree angle to look at the clear sky.

Let's go, this kind of personal habit is not a disease, why do you love it.

Cheng Chubi continued to devote himself to repeated experiments, and after many tests, he got the most suitable ratio of essential oil and goat milk.

At least the two soaps that are most in line with Cheng Chubi's preferences, and of course, he has not forgotten to make the same moisturizer.

Only then did he take the sample to the backyard to meet his mother. came to the backyard and asked the maid, not surprisingly, the mother really stayed in the study.

When I arrived outside the study, I saw my mother writing there energetically.

It wasn't until Cheng Chubi deliberately put down the footsteps and walked into the study that his mother-in-law Cui Shi seemed to notice Cheng Chubi's arrival.

"It's San Lang, you wait, my mother will copy this page before I talk to you......"

Cui, the mother, just raised her face and smiled perfunctorily, and continued to bury herself in copying books.

For his mother's behavior, Cheng Chubi had already seen it, and began to wander around in this study with an inner space almost comparable to the main house.

The abundance of books in it is that even Cheng Chubi, a well-informed traverser, is also smashing his tongue.

What he was struck by was not the number of books, but the fact that there were still quite a lot of bamboo slips on the shelves, and a roll of bamboo slips would not be too light.

Cheng Chubi remembered that he had seen a record in later generations, the historical record was about 500,000 words, and the content of 500,000 words, the bamboo cost was simply more than one ton.

It is no wonder that the ancients liked to use the weight of the car to describe a person's talent and knowledge, well, the main reason is that the knowledge is too heavy.

After walking around for a while, he finally heard the call of his mother-in-law Cui, and Cheng Chubi returned to the case.

Looking at the mother Cui Shi who was rubbing her sore wrists, Cheng Chubi couldn't help but feel distressed. "Mother, do you have to copy it yourself?"
