Li Er didn't say what compensation he wanted, and Zhang Nan didn't ask anymore, Li Er saw that Zhang Nan agreed to his request, so he took Zhang Nan to Princess Changle's Fengyang Pavilion, but Princess Changle went to where Queen Changsun was, so Zhang Nan didn't see the face of the eldest princess of the Tang Dynasty.

Princess Changle was not there, and Li Er didn't want to make an assertion and pulled out the daffodils planted by his baby daughter, so he said: "Qingquan, since Lizhi is not here now, let's come back another day, anyway, this flower will not bloom now." ”

Zhang Nan nodded, after all, if the master is not there, it is not good to use other people's things privately, Zhang Nan still understands this truth. But since Li Er promised himself, it must be able to do it, and sure enough, at dinner, Liu Bing took a few little eunuchs and brought three sacks of daffodils to his house.

"Lord Zhang, you want this flower, our family still thinks who has such a big face, if it is Lord Zhang, our family will be able to understand." Liu Bing saw Zhang Nan and said with a smile.

"Oh? Why? Zhang Nan asked strangely.

"Princess Changle can't get these daffodil treasures, that is, you, Lord Zhang, have such a big face to pull out all these daffodils." Liu Bing said with a smile.

"Okay, okay, don't praise me, this is a matter approved by the emperor, and it has nothing to do with my face, don't talk nonsense." After Zhang Nan finished speaking, he deliberately looked around, and found that Cui Yue was still in the backyard and did not come, so Zhang Nan relieved his heart.

If Cui Yue misunderstands what he and Princess Changle have, it will be more than worth the loss, Zhang Nan said in his heart.

"But we still have to ask Master Zhang, what are you doing with so many daffodils." Liu Bing asked puzzled.

"What do you think those perfumes are made of, they are all made of flowers, and I make these daffodils just to make a daffodil-scented perfume." Zhang Nan said.

As soon as he heard that it was a perfume, Liu Bing immediately reminded: "Lord Zhang, after this daffodil-flavored perfume comes out, Lord Zhang must give us a bottle." Liu Bingsheng was afraid that Zhang Nan would forget about giving him a bottle of perfume.

"Don't worry, you go back and pay off, and when the first batch of narcissus-scented perfume comes out, I will definitely give you a bottle." Zhang Nan said. After receiving Zhang Nan's assurance, Liu Bing happily returned to the palace to recover his life, and Zhang Nan began the first step of his own homemade perfume manufacturing.

After replacing a complete set of distillation equipment from the system, Zhang Nan was ready to start making perfumes.

Cui Yue heard the movement in the backyard, so he ran out of the room to see what was going on, but Cui Yue was startled by the sudden appearance of the distillation equipment.

"Lang Jun, what are you doing?" Cui Yue came to Zhang Nan's side, knocked on the distillation equipment with his hand, and asked with a puzzled expression.

"Lang Jun is going to make perfume today." Zhang Nan said.

"Perfume? Aren't all the Red Makeup Pavilion for sale? Why does Lang Jun still make it himself? ”

"Hey, those perfumes are too expensive, Lang Jun decided to make them himself and reduce the cost, so that the price of perfumes will come down." Zhang Nan asked while operating the still.

"But the price of this perfume has come down, won't the queen make less money? Can this queen be willing? Cui Yue asked, although this Red Makeup Pavilion has been operated by several Duchess and Duchess looking for people, but Cui Yue knows that the big boss behind this Red Makeup Pavilion is the eldest grandson queen.

"Yue'er is so careful, Lang Jun asks you, do you know who is using these perfumes now." Zhang Nan asked.

Others don't know, Cui Yue knows that the consumer group for this Red Makeup Pavilion is for, because the cosmetics provided by Zhang Nan are all ready-made products that have been exchanged from the system, although most of them are domestic cheap brands, but the prices in the Red Makeup Pavilion are still expensive, so the sales of these high-end cosmetics in the Red Makeup Pavilion are not very good, and almost all of them have become supplied in the palace.

"This is naturally used by the eldest grandson, the queen and the ladies of the harem." Cui Yue said.

"Well, that's right, I reduced the manufacturing cost of perfume like this, although the price has come down, but the sales have gone up, these perfumes will not only be the emperor's harem at that time, the wives of those officials will be shy away from perfumes at this price before, but at my price, they will definitely pay for it, so don't worry." Zhang Nan said with a smile.

In the past, the perfume sold by the Red Makeup Pavilion was expensive, and the wives and concubines of some officials could afford it even though they gritted their teeth, but there were very few who could really buy it with all their hearts, and the fashion trend of the people was all looking at the palace, so this time the price of perfume came down, and those officials and wives who like to chase the trend will definitely pay for it.

And as long as the essential oil is refined, the perfume can be divided into several grades, so that the cost of the grade does not only depend on the brand of perfume, but also becomes the fragrance concentration of the perfume, and the retention time to divide.

According to Zhang Nan's idea, as long as this essential oil can be refined smoothly, even the most ordinary people in Datang can buy a bottle and go back to make it fresh.

"No matter how rich the concubines in this harem are, it is impossible for them to be richer than the common people, so ah, I am not letting the queen make less money, but helping her earn more." Zhang Nan said with a smile.

Cui Yue heard Zhang Nan say this, and after thinking about it for a while, he understood the reason, so he didn't say anything, but went to the side to watch Zhang Nan operate this still.

The principle of distilling essential oils in a still is very simple, fresh raw materials are put into the still, and the steam is sent by the lower heat to evaporate the essential oil of the plant. The water vapor containing the essential oil is collected and cooled through the duct, and the steam is cooled into a liquid, and then separated according to the difference in the specific gravity and density of the water and the essential oil, so that the essential oil is successfully manufactured.

Zhang Nan didn't doubt the effect of this still at all, so he handed over the still to the people with peace of mind, let them stare at the water flowing out of the conduit, and after collecting a basin, just separate the grease-like things on it from the water, and after a simple arrangement, Zhang Nan took Cui Yue back to the room to rest.

Feudalism is this good, as long as you have the right, then whatever you say is what, and the subordinates in Zhang Nan's mansion are loyal one by one, and they all work with a spirit to complete the things that Zhang Nan explains.

Early the next morning, Zhang Nan got a small jar of daffodil essential oil, so Zhang Nan asked Cui Yue to put away the small bottle and go to the court.

"Although the home-made perfume I make now is not as good as those foreign brands in the system, no matter how bad I do, it is also my own, if I rely on the system all my life, then when I burp, Datang is estimated to have to reverse history, so independent scientific research still has to be engaged." Zhang Nan thought of this, so he went to the court.
