The level of security in the chemical laboratory is very good, second only to the Gunpowder Research Institute of the Nanshan Annex.

Except for a group of alchemists who have obtained Chen Xu's permission and the students and professors of the College of Engineering who need to take experimental classes, ordinary people cannot enter here, because chemical experiments are full of all kinds of uncertain factors, and under such primitive conditions, exploding meals are simply commonplace.

Since the opening of this laboratory last year, although there has been no major accident, there have been several small accidents, once a monk secretly drank a sip of purified alcohol, drunk for a few days before waking up, but it is estimated that the stomach and intestines were burned by a high concentration of alcohol, and he almost hung up directly after not eating and drinking, and he was sent home by the engineering college and now he does not know whether he is alive or dead.

Another time was when the sulfuric acid was purified, the still suddenly exploded, and the sulfuric acid splashed out without knowing the concentration and burned the two Fangshi, although both of them were not worried about their lives, but they were injured to varying degrees, and their faces, hands, and arms were full of scars eroded by sulfuric acid, in fact, if Chen Xu was there at that time, the consequences would definitely not be so serious, because he learned in high school chemistry class, and he couldn't wash with water immediately after being splashed with sulfuric acid, but blotted it with a dry rag and then washed it with water, and then applied baking soda solution, But Chen Xu was not in the laboratory at that time, several alchemists were burned by the explosive sulfuric acid and the pain was unbearable, and the other alchemists hurriedly cleaned with water, but the consequences became very serious, and when Chen Xu arrived at the laboratory, the skin of the two alchemists who had washed turned red, and after two days, it turned black and cracked, and then left scars all over the body.

These two alchemists became the first pioneers of the Great Qin Empire's chemical experiments to be injured, and their scars also became a symbol of glory.

However, even if it is glorious, the two alchemists were later beaten by Chen Xu, and they formulated a stricter experimental discipline, all chemical experiments in the future must bring a full set of protective clothes, hats, masks, gowns, gloves and even glass glasses, and specially explained a simple treatment method, but it is not an egg, for these wild people who are used to being free, all the protection is just an obstacle that restricts them from pursuing the way of heaven and natural nature, and they can't hold on for a few days and start to do experiments with light ketones, After three or five times, Chen Xu didn't bother to say it, a group of fools deserved to die.

Under this nature of pursuing nature, there have been several accidents that are not too big one after another, and a few Fang Shi have also been injured, but fortunately, the problem is not big.

However, as time slowly passed, after a few accidents in the laboratory, a group of alchemists had a lot of experience in dealing with accidents in a timely manner, and have been calm in recent months.

But what makes Chen Xu depressed is that since the establishment of this laboratory for more than a year, basically no fart has been studied, and a few alchemists are fooling around in it every day with a good salary, and all kinds of ore powder and sulfate lime water are poured around, just like playing with a family, they have begun to become a little addicted.

A group of alchemists who were busy in the laboratory were overwhelmed by the sudden influx of guards and more than ten baskets of osmanthus chrysanthemum petals, so they could only stare around one by one to say hello and wait for Chen Xu's orders.

"Ben Hou is going to make a few perfumes, these petals are the raw materials, you wait to wash the still and set aside!"

Chen Xu was too lazy to talk, and commanded a group of alchemists to start cleaning the distillation equipment, while the remaining helpers selected some complete and clean flowers from the bamboo basket according to Chen Xu's requirements, and after half an hour of busy work, the distillers and flowers were ready.

Because of the experience of distilling alcohol and copper sulfate, a group of alchemists are very familiar with the process, Chen Xu briefly mentioned a few words, and soon some osmanthus was put into a distillation bottle, and the lower part began to be heated by a furnace fire, as the water in the still began to boil slowly, after more than ten minutes, it was already visible that fine grease-like particles began to appear on the wall of the distillation tube and began to gather, but it seemed that it would take half an hour to drip out.

Distillation is the easiest way to purify essential oils, but it is also the most complex method, simple because the principle is the simplest, complex because the operation is the most complicated, before there is no good extraction solvent and equipment to extract essential oils, the only successful is distillation.

And whether it is distilled with dried flowers or flowers Chen Xu doesn't know, but according to Chen Xu's idea, whether it is flowers or dried flowers, as long as there is a fragrance, it will definitely be able to steam out the essential oil, and the final result is just the amount of it, just like making small grinding sesame oil, it is not that fresh sesame seeds are not good, but the oil yield of fresh sesame seeds is relatively low.

With the passage of distillation time, the osmanthus in the distillation bottle continues to wilt under the action of steam, and a full jar becomes a large half jar, and the oil droplet particles gathered in the distillation tube are also more and more, densely began to flow downward, and the steam from the nozzle continued to emit out, and the whole laboratory was filled with a sweet smell of osmanthus that could not be dissolved.

"Hey, that's delicious!"

"It's really fragrant, it's estimated that it will be sweet to and pee tomorrow!"

Several alchemists stood by and discussed in a low voice.

Chen Xu's face was so dark that he couldn't see his eyes clearly.

Nima Laozi is used to wipe the face and body, a group of fools and rammers on dog days.

"Use saltpeter to make a basin of ice water, soak the linen cloth in ice water, and wrap the condenser tube to cool down!" Chen Xu felt that it was impossible to let the steam evaporate in vain, this essential oil is not like distilled copper sulfate, the distilled gas is directly passed into the water, but it must be naturally cooled and condensed, because the temperature of the air flow is too high, Chen Xu estimates that most of the distilled essential oils are actually emitted into the air with the water vapor.

"Yes, Master Hou!" A few alchemists hurried to prepare, and quickly prepared a basin of ice water with saltpeter, and then soaked a rag and wrapped it in the condenser tube, although the situation in the condenser pipe was not visible, but the water vapor coming out of the outlet was indeed much less.

Another seven or eight minutes passed, and finally a drop of pale yellow oil dripped from the mouth of the tube into the glass bottle below.

Looking at such a pitiful drop that took out for a long time, a group of Fang Shi stared at each other with big eyes.

"Master Hou, this is too slow, it is estimated that it will take several days to distill these more than ten baskets of flowers, and in the end, it is estimated that you can get up to three or five taels, and you can drink it all in one sip!" A Fang Shi said with a dry smile cautiously.

Chen Xu didn't bother to talk to this group of fools.

Essential oils and essential oils, naturally plant essence, I heard that a few tons of rose petals can finally refine a kilogram of rose essential oil, although Lao Tzu is not refining pure essential oil, the moisture content is large, but these more than ten baskets can be made out of three or five taels of impure essential oil, which is also a great success.

But what Fang Shi said is also quite reasonable, one still is too small and too slow, but there are still several sets of stills in the laboratory at the moment, so Chen Xu ordered everyone in the laboratory to help, clean all the stills and start distilling the petals, three of which are distilled osmanthus, two distilled chrysanthemums, and one distilled messy so-called vanilla.

However, even if all the stills come in handy, the speed is still very slow, but given that this is a laboratory distiller, Chen Xu can only use it first, if the perfume is successful, he can design a set of larger distillation equipment, and after the beginning of spring next year, he can collect roses, orange blossoms, grapefruit peels, jasmine, gardenias and other flowers and fruits with obvious fragrances to make perfumes with different flavors, and then he can open up another more luxurious way to make money.

Even Chen Xu instantly thought of the name of the perfume, which was called the Hundred Flowers Fairy, and he could also make up twelve different perfumes according to the twelve flower gods of later folklore, so as to seduce the wives of the princes and princes and the wealthy businessmen of the Jia family to buy ......

I'm rubbing, Lao Tzu is not a little shameless.

Chen Xu came back to his senses and despised himself a little, but today he was gently reminded by the water before he remembered to refine the excess flowers into essential oils, but he actually thought of making a fortune again.

Lao Tzu is a Shangqing and Zuo Xiang, the top nobles of Daqin with two marquises, and now there are groups of wives and concubines in the grain fields of 10,000 mu in Fuzhong, and many commercial properties are making money every day.

But...... That one...... It's a bastard if you don't make money, such a good opportunity to make a fortune is in front of you, and if you don't make a profit, I'm afraid you will be struck by thunder!

Chen Xu was very entangled, pinching his chin and keeping his eyes spinning around a few stills in the laboratory.

Distillation and refining essential oils is really slow, and soon half an hour passes, and only a few drops are extracted in each bottle, and the bottom of the bottle can't be covered, and it is estimated that all of them add up to half a tael, so Chen Xu told a group of alchemists to continue refining essential oils, and they must carefully seal the collected essential oils, so that they cannot be volatilized.

Next, Chen Xu went to the College of Engineering to inspect it, and then took a carriage to Zhongshu Province to inspect his one-acre and three-point land.

Recently, with the gradual pacification of Lingnan, and the Mid-Autumn Festival and the Autumn Market will start one after another, so the main task of the imperial court is to arrange festival celebrations and the world, the three provinces and six ministries are very busy, Qin Shi Huang has canceled the Wu Dynasty, every day the civil and military officials only need to go to the early dynasty, but even the early dynasty Chen Xu has almost never been to the recent past, has been at home to take care of his three big-bellied wives, and plans to arrange for people to go back to their hometown after the Mid-Autumn Festival to bring their father and mother and Han Tian and millet to Xianyang for the New Year, because as Lingnan settles down, maybe Han Xin will come back soon, so that the family that has been separated for more than two years can get together for a reunion.

So the court is busy, but the officials below are busy, and the busiest are the officials of the six ministries and the Inner History Mansion, Chen Xu is a little idle, because he is too idle, half a month ago, he also opened a baking shop near Qinghe Garden, specializing in selling egg rolls, bread and moon cakes, and continues to make shameless money. I heard that the sales of baking shops are hot, especially moon cakes, how much they make and sell every day, and they are completely in short supply, so Chen Xu wrote a detailed production method of moon cakes and published it in Daqin Metropolis Daily, so that people all over the world can eat this holiday food that he invented.

And today, in addition to the pain in the egg, he unexpectedly found a luxury product that was in line with the concept and purpose of his Qinghe store...... Perfume.

Later generations recognized that there are two kinds of best money-making groups, one is women, the other is children, from the portrait of consumer groups, as the pillar of the family and the main force of national construction, men are the lowest level of consumption, men live not as good as dogs, this is the famous Taobao according to the conclusion of big data, pets spend more money than men.

Although the current situation and consumption level are different from those of later generations for more than 2,000 years, women's beauty love has not changed in the slightest, which can be seen from the women who wear various colorful skirts on the streets.

Although Daqin is not rich in materials, but for the rich and powerful families in Xianyang, all kinds of consumption has always been at the forefront of popularity, and now the clothes and ornaments of pedestrians on the street are not the same as when Chen Xu first came to Xianyang six years ago, the women's college and Qinghe store designed a fusion of ancient and modern Chinese and foreign different history and ethnic characteristics of the clothing has become the latest trendy style, the noble lady on the carriage and the big daughter-in-law and little lady who laughed and swaggered on the street, wearing a fluttering skirt, a loose and fitting embroidered skirt, Slim-fitting cheongsam, short skirts with exposed snow-white thighs, etc., and men also have Confucian clothes with large sleeves, monk's clothes with short clothes and pants, narrow-sleeved and tight-fitting samurai clothes, and even small stand-up collars and straight-leg pants.

Through the acceptance of clothing by the people of Daqin, it seems that there are people in any era who are constantly interpreting and chasing the latest trends, especially princes and princes and a large number of wealthy people, and now the commercial law has been lifted for several years, and the status of businessmen has been greatly improved at the same time, they are also measuring the world with money, spending a lot of money to buy real estate and various luxury items that were not allowed to be worn and owned before, silk, porcelain, glass, red wine, jade, jewelry, are the objects of enthusiastic pursuit and rush to buy by wealthy businessmen.

Most of the luxury items on the market were basically purchased by the new merchants and aristocrats.

Among them, the women in the mansions of princes and princes and wealthy businessmen are also a huge consumer group, but because there are relatively few luxury items for women on the market, except for a few simple makeup accessories such as rouge, lipstick, hairpins, and jade pendants, all goods are pitiful.

Chen Xu first broke through the taboo in the Qinghe store to open a women's clothing monopoly, developed women's underwear, although it is an extremely private thing, but it quickly occupied almost all of the high-end market, the wife and daughter of the prince and even the concubine princess in the inner courtyard of the palace, to buy underwear must go to the Qinghe store, only the two red seal characters embroidered on the corner of the clothes are the genuine feeling of wearing on the body to enhance personal identity and charm of the item, naturally with the blessing of the Qinghe Marquis, you can make yourself more beautiful.

Of course, not to mention, when wearing the underwear and chic dresses purchased in Qinghe Villa, every time my husband's eyes will change to varying degrees, with a hint of heat in the surprise, and a trace of flesh pain in the heat.

And once the perfume that can increase the temptation of body fragrance is launched, Chen Xu can probably imagine the madness of these women in the aristocratic and rich mansions.

It is the bounden duty of every woman to seduce her husband, who likes to visit the garden, to come home.

This is not the next generation, the husband is unfaithful and can still fight a lawsuit to divorce and divide the family property, in this era, it is allowed for men to visit the kiln, and it is normal for rich and powerful men to take concubines, if it is a top marquis like Chen Xu, there is a fixed number of wives, but there is no restriction on concubines at all, so all the princes and princesses are almost all wives and concubines in the family, and the children are in charge of the property, and the concubines are also indispensable helpers to support the prosperity and growth of the family, so all the women in the families of the princes and princesses, Both wives and concubines hope to be able to firmly tie their men, get more favor, and their children can be firm with more identity and status.

And perfume is not destined to be a luxury item that those dusty women in Quyuan Cottage can afford.

According to Chen Xu, if he didn't know how to do it himself, it would probably hurt to buy it.

Because the output is really low outrageously, more than ten baskets of flowers and plants got today, and finally can get out a few taels of essential oils even if it is a bumper harvest, and finally it has to be diluted with high-purity alcohol, and then sealed with exquisite crystal bottles, when the time comes, a bottle even if it is the lightest fragrance and the worst quality perfume, it is estimated that it will cost thousands of dollars, if it is measured according to the pricing of Qinghe Liquor, it is simply sorry for the conscience of heaven and earth if you don't buy tens of thousands of dollars.

However, Chen Xu is still hesitant about the pricing of perfumes.

Although there are many princes and princes of Great Qin and wealthy businessmen, women still belong to the discriminated group after all, whether it is social status and family status is not high, so the money under control is also very small, and too high pricing will inevitably cause many adverse consequences.

The man invited guests to dinner in the hotel, and even slapped his swollen face and became fat for the sake of face, yelled at a bottle of Qinghe wine, and felt distressed at most after drinking, but if a woman secretly spends tens of thousands of dollars to buy a bottle of perfume, it is estimated that she will be beaten to death by her husband when she goes home, and the perfume will inevitably be cheaper in the end.

Therefore, the pricing of perfume should not be as black as Qinghe wine, and it still needs to be carefully considered and discussed, after all, this is not the era after women's emancipation.

But in any case, once the perfume is on the market, it will inevitably quickly arouse the crazy pursuit of all women, there is no doubt about it.

Chen Xu sat in the carriage and pinched his chin all the way to ponder about perfume, from branding to packaging to advertising to pricing, if you want to make a fortune, this one-stop business process is inevitable.
