Put the petals in a container and compact, then put in some water, put in the petals again, compact again, put the petals again, put them in three layers in a row and start distillation and refining.

Extracting the essential oils from the petals is the most important step.

In the Middle Ages, vegetable oils and animal oils were also used as essential oils for perfumes.

It's too complicated to fix these things, and the technology of this era is not easy to achieve.

Besides, I don't want to be so heavy.

Nowadays, the sachets used are also put into the sachets with flowers or refreshing herbs, and the better ones will use incense.

While the oil is insoluble in water by compacting the petals in a boiling container, the essential oil can be extracted by separating it from a condenser tube.

Li Zheng was holding the book and still looking at the manufacturing method of cologne.

Cheng looked at a few clay pots and stills made of bamboo pipes, which at first glance looked quite like this.

It is rumored throughout Chang'an that Li Zheng is crazy, and some people feel that God is jealous of talents.

The five surnames breathed a sigh of relief, and it was very good news for them that Li Zheng was crazy.

How many people would believe the knowledge of a madman?

Li Tai also found Li Zheng, looked at Li Zheng's demeanor and said with a worried expression: "Li Zheng, I heard that the flowers in the radius of ten miles have been picked by you Jingyang?" ”

"Well, I'm going to pick all the flowers in a hurry, and in a few days, the flowering season will be completely over, and where will I pick any flowers."

Looking at Li Zheng's expression again, it didn't seem to be anything special, Li Tai asked again: "Li Zheng, even if you pick all these flowers, they won't wither, what's the use?" ”

Li Zheng shook his head and sighed, "What you see is that one plus one equals two, but what I see is different." ”

Li Tai hurriedly said: "Isn't one plus one two?" ”

"I sympathize with your intelligence, chickens and ducks talk in vain."

"I think you're really crazy."

Whereas, Li Tai did not receive formal knowledge of chemical physics.

Li Zheng didn't plan to deal with this fat man, after all, the fat man didn't have this knowledge.

Then he whispered to Li Tai: "Fatty, the so-called learning and living to old age, knowledge is always the most important, the more knowledge you have, the more choices you have." ”

Li Tai tugged at the corners of his mouth and smiled reluctantly, "Do you think I don't know?" Ever since I was a child, I have listened to the lectures of various famous scholars and Confucians. ”

With a long sigh of emotion, Li Zheng said, "Then what has His Royal Highness the King of Wei learned?" ”

"I've learned ......" Li Tai thought for a while and said: "I have learned the truth, the truth of being a courtier, and the truth of being a person." ”

"What else?"

"And ......"

Li Tai's face was anxious.

Seeing that he couldn't speak, in fact, the complacency of knowledge is a very terrible behavior.

It's strange that the direction of learning knowledge is different.

Li Zheng patted Li Tai on the shoulder and said, "To me, you are just mortals, and some of the knowledge I use is like a miracle to you. ”

"Miracles? It's like you used to send people to heaven? Isn't it just a large Kong Ming lantern? How stupid you are to me. Li Tai said.

"Did anyone do it before me?"

When Li Zheng said this, Li Tai thought back that it seemed that no one had really done it.

It's like in the era of sea voyages, when Columbus came to a land with a backward civilization and shot him with a musket a hundred meters away.

It was a miracle for the natives.

They even bow to the shrine.

Moreover, scientists have deduced that if there is a civilization that can use time as a weapon, then this civilization is a god to the backward earth.

You will be in awe, you will be afraid, and you will be even more afraid.

But when you have their knowledge, you also find that it is nothing more than that.

This is the knowledge gap.

By analogy, knowledge has been indispensable since the beginning of the wilderness.

Li Zheng sneered and said to Li Tai: "Whether you believe it or not, in short, I can keep the fragrance of flowers." ”

"Flowers will always wither, and the most unretained thing in this world is the fragrance of flowers." Li Tai sighed and said, "I think you are really crazy. ”

Li Zheng grinned, "This is knowledge." ”

Knowledge......

Li Tai muttered to himself: "Li Zheng, you have built a Jingyang Academy, what do you want the academy to become." ”

"I never thought about what it would look like, I just taught children knowledge, and I don't think I'm qualified enough to be a teacher."

Li Tai glanced at Li Zheng again, and felt that he was not crazy again.

"I remember when I was a child, the primary school in the village had all the students from the same village, and sometimes it was your relatives who taught or lived next door to your house."

"Or maybe when your mother chases you with a broom, you'll meet a few classmates."

"Or when you buy steamed buns on the side of the road, you can still see your classmates running for their lives on the street, and his mother is chasing and killing in the back, crying and howling wolves all the way, not to mention how exciting it is."

This guy has a wistful look on his face and a smile, as if he has really experienced it.

On the first day, the distilled sesame oil was only half a bowl.

Quickly poured it into the bottle and sniffed it carefully.

When making perfume, just add a little drop of two or three drops.

Such a small half bottle is enough for more than ten bottles of perfume.

After saving it, clean it up.

Go home for dinner tonight, today is the Mid-Autumn Festival.

At home, Li Daxiong personally cooked only a stewed pig's trotter.

Li Zheng went to the kitchen to add a few more dishes.

Di Renjie's father hadn't come back from the East Palace yet, so he called Di Renjie to eat together.

Pei Xingjian and Xue Rengui sat together.

Chu Suiliang and Shangguan Yi also sit.

Xu Jingzong and Li Yifu also came.

Obviously, these people were all invited by Li Daxiong.

The house was lively, and the village killed five pigs to celebrate the holiday.

They went to the house until late at night.

On the second day, Li Zheng, who got up early, continued to distill the floral essential oil.

Until noon, Empress Changsun came in a sedan chair, followed by Li Zhi and Li Lizhen.

Li Zheng calculated the hour, and it happened to be a meal.

Did the people from his Li Er's family come to visit with food?

It's terrifying.

Li Zheng immediately saluted when he saw the comer, "I've seen the queen, I've seen Her Royal Highness the princess, I've seen Her Royal Highness the King of Jin." ”

Empress Eldest Sun looked at Li Zheng and said, "They all say you're crazy. ”

Li Zheng shook his fan and said: "Others laugh at me for being too crazy, I laugh at others for not being able to see through it, and I don't know the tomb ......of Wuling Haojie."

"No flowers, no wine, hoe fields." Li Zhi said in a milky voice: "I have read your poems. ”

Seeing that Li Zheng's expression was normal, Empress Eldest Sun nodded reassuringly, "It's not as crazy as others say, it seems that you Li Zheng is quite normal in this palace." ”

"Humph!" Li Lizhi turned her head disdainfully, "Sure enough, I'm pretending to be crazy and stupid." ”

This little girl is still a little tsundere.

Visiting the horse rings here, Empress Changsun found that the place was surprisingly tidy, and the horse rings in other places were dirty and messy.

"Do you clean every day?" Empress Eldest Sun asked.
