This is crude distillation, and after the first distillation, after the separation of oil and water, it will be distilled two or three times to obtain high-purity flower oil.

Dusk had seen a large pile of gold and silver beckoning to him.

Xu Miaojin thought thoughtfully, "You want to make spices?" ”

Spices are indeed expensive.

In particular, the tribute spices are far more expensive than those circulating in the private market, but the spices are generally in powder or granular form, and there is no liquid.

Dusk smiled, "Shower gel." ”

Xu Miaojin had a question mark on her face, and pouted dissatisfied with the flickering of the dusk, "You said you were going to make Chanel before." ”

Twilight laughed dryly, "I said casually. ”

Xu Miaojin: "......"

After all, it was the Huanghua girl, embarrassed to stay here for too long, and said softly: "I actually came today to tell you two things, one is to say, Zhu Di ascended the throne, and the proposed year name is Yongle, and the second thing, Zhu Di ordered in the morning that Fang Xiaoru will be executed in Jubaomen, and the ten clans will be punished." ”

Confirmed.

Dusk really didn't make up nonsense, he was really a time-traveler who could predict something in the future.

Dusk was gloomy.

failed to save this scholar, and felt a little guilty in my heart.

got up, bent down and bowed in the direction of the treasure gate in his heart, and sighed lightly: "Mr. Wucheng, let's go." ”

Fang Xiaoru, the word Xizhi, the word Xigu, the number Xunzhi, once named his study with "Xunzhi", because his hometown used to belong to the city, so called "Mr. Xucheng"; And because when he was a professor in Hanzhong Mansion, King Shu Xian gave his reading place "Zhengxue", also known as "Mr. Zhengxue".

He died on July 25, 1402, at the age of forty-five.

Follow-up text.

The only Confucian in history who was condemned to the Ten Clans.

Wu Youbi whispered: "Brother Dusk, the direction is wrong, over there, and it hasn't been executed yet." ”

Dusk is extremely awkward.

Xu Miaojin said again: "That day, when you talked to Zhu Di in the Jinshen Palace, I already knew that although you didn't save the filial piety below, you also tried, but the world is like this, you and I mortals can't resist the imperial power after all." Don't feel guilty and blame yourself, and you have saved Huang Guan, a three-yuan genius, who is worthy of being a scholar in the world. ”

Xu Huizu is now in trouble.

It does not mean that Xu Miaojin is in a bleak situation, with the support of Queen Xu, the Xu family is still a relative of the emperor after all, and there are many Jianwen old people in the palace, so Xu Miaojin can still know a little news in the palace now.

"I'm leaving."

Xu Miaojin left with Xu Yin.

Dusk sat down again, and out of the corner of his eye, he found that Wu and Bi were not in the right mood, and sighed secretly.

I'm afraid this is one of the reasons why Wu Youbi is reluctant to join the office.

Not reluctantly.

If Wu and Bi continue to grow savagely, if he forcibly makes up for his simple thoughts about his career, and really goes to participate in the imperial examination as an official in the future, then the Ming Dynasty will have one more Qing minister at most.

But there will be one less great Confucian and educator.

Time of day.

Dusk finally got the purified lotus oil, and the teacup-sized porcelain vase was half full.

Enough for now.

In the evening, Wu Pu returned, directly pulled Dusk into the study, and said sadly and shockedly: "You are indeed right, Fang Xiaoru will be executed in Jubaomen, the tenth clan, and his friend and protégé are the tenth clan." ”

is sad because of Fang Xiaoru's death.

Shocked, because dusk can really predict the future.

Dusk nodded, "Uncle Wu now believes that I am a traverser?" ”

Wu Pu retracted his desolate thoughts and said puzzledly: "What is a traverser?" ”

Dusk smiled: "The traverser, it's very simple, it's actually a profession, it's almost the same as the Xiangshi, but the traverser is stronger, because he is the chosen one, so he can truly predict the future, while the Xiangshi can only speculate." ”

These words also fooled Zhu Di.

It's just that I didn't dare to say the chosen son at that time, otherwise Zhu Di heard it, yo, I will be the son of heaven, you said that you are the chosen son again, and you want to rebel in your feelings?

Drag it out......

Then I probably won't be able to get out of the Forbidden City.

Wu Pu suddenly, "Can it be compared to "Push Back Picture"? ”

Dusk thought for a while, "In the past few hundred years, I am more accurate than "Tui Bei Tu", but six or seven hundred years later, then "Tui Bei Tu" is more accurate than me. ”

Hundreds of years?!

Wu Pu was stunned on the spot.

After a long time, after reacting, his eyes at dusk became much hotter, and he was like a god.

Dusk felt uncomfortable and said with a smile: "Uncle Wu doesn't have to be like this, I'm in your house now, you can treat me as your nephew, if you don't dislike it, we will be a family in the future." ”

Wu Pu smiled.

I didn't see anyone wrong, Dusk does have a maturity and stability different from his age.

Very good.

After determining the ability of the dusk traverser, Wu Pu didn't mind the tossing at home at dusk for the past few days, and it was still the old rule at night to check the knowledge of the two.

Wu and Bi passed the test smoothly.

At dusk was reluctant, and there were some words in the "Thousand Words Text" that I couldn't recognize.

Wu Pu is not in a hurry.

Just re-learning this speed at dusk, it will only take about a month or two, and you will probably be able to read the Four Books and the Five Classics.

Twilight continues to start a business.

Yesterday the lotus oil has been distilled, and today it is necessary to make caustic soda.

Caustic soda is sodium hydroxide.

The alum used in the fritters is also called alkali, but it contains impurities such as aluminum, so it is still made by chemical reaction of lime and shell powder.

Dusk picked up the mussel shells back to try.

If the mussel shell is not good, sodium hydroxide can also be extracted from the plant ash.

The mussel shell is put into the stone and crushed into powder, which is the original tool used to mash peanuts, sesame seeds and other crops to make rice cakes, similar to the crushing machine of later generations.

It's a physical job.

Wu Pu didn't have a stone at home, so he went to Hu Guang's house next door to borrow it.

After a busy morning, after getting a few kilograms of mussel shell powder, I returned home and found a large basin, mixed hydrated lime and mussel shell powder evenly, added water and stirred constantly.

It's still a physical job.

The calcium hydroxide in the hydrated lime and the sodium carbonate in the mussel shell powder must be fully reacted to obtain a calcium carbonate precipitate and a sodium hydroxide solution, and care must be taken.

Sodium hydroxide solution is alkali and easily burns the skin.

There is a thrilling finish.

The sodium hydroxide solution is put into a makeshift stove, heated and distilled to remove the excess gouache, and the sodium hydroxide precipitate is obtained, which is also the caustic soda of the Eight Classics.

It's just that because it contains a small amount of impurities, it does not show colorless crystals, and there are some white opaque crystals.

There should also be impurities such as potassium.

At dusk, I went to the kitchen to get salt, made saturated brine, and rinsed the sodium hydroxide repeatedly.

After that, pure caustic soda was finally obtained.

The principle is simple, because the saturated salt water is saturated with sodium ions, and all sodium hydroxide will not dissolve, while other impurities will dissolve into it.

Wine, lard, caustic soda, lotus oil.

All have been made.

Just wait for the last step and you're done!
