Meng Yi refused, and Chen Xu once again hit a wall.

Back to the Zuo Prime Minister's Mansion in a bad mood, Chen Xu sat alone in the study and sighed in a daze. Several maids had never seen their marquis feel so depressed, and they were all so scared that they stood outside the door and didn't dare to go out.

It should not be difficult if you really want to investigate this matter, but after checking it out, it was a bit of shit and it couldn't be washed clean. The reason was naturally the concerns of Feng Quji and Meng Yi. No one in Wang could offend him, so if he wanted to investigate, he had to do it himself. Meng Yi and Feng Quji had already expressed that they would not get involved in this trouble.

But for Chen Xu, it was definitely a wrong decision to arrange someone to investigate in person, because he was in charge of the Secretariat, neither the Supervisory Province nor the Ministry of Justice and the Ministry of War, and had no right to investigate at all. Once the matter of his secret investigation was exposed, it would cause dissatisfaction among many people, and he had no intention of opposing himself and Wang. Such thankless things would naturally be the best for others to do.

Unfortunately, he chose two powerful and capable people not to accept the challenge.

But in Chen Xu's opinion, if this matter is not handled properly, it may really lead to a disaster.

Li Mu exists like the god in the minds of the people of Zhao. If this matter is not handled properly, the people of Zhao will hold grudges. Over time, not only will they not calm down slowly as Meng Yi and Feng Quji said, but they will accumulate more hatred and anger. Finally, they will count this tone on the emperor. Once more conflicts occur, more hatred and conflicts accumulate, it is not impossible to finally rebel.

With his continuous efforts, Daqin finally had the opportunity to develop rapidly. If there was another turmoil, many reforms that had just begun would be wasted, and wars after war will eventually slowly wipe out the little wealth that has been accumulated so hard.

Just attacking the Western Regions and Lingnan, the imperial court consumed more than five million stones of food and grass every year, and more than 100,000 prisoners and slaves were recruited. Now Lingnan is about to conquer, and the army cannot be quickly dismissed. Instead, it will be retained for at least several years to maintain peace in the Lingnan area. This consumption will be continuous. A Xiang rebellion, in the end, according to the court's estimate, the loss is at least three million stones. Two years later, the production and life of the local people has not recovered. Tens of thousands died of military disasters and hundreds of thousands were displaced. If there is another rebellion in the north, the turmoil will be even worse. A large army will be summoned to recruit soldiers, food, grass, chariots and horses. In a war, no matter the outcome, it will greatly damage the vitality of the Qin Dynasty, and countless people will destroy their families...

After sitting in the study for an hour, Chen Xu was depressed and temporarily put down this unthinkable problem and ordered the guards to prepare a carriage and horse to go to the Institute of Engineering.

The chemistry laboratory was filled with a strong fragrance of flowers.

Several glass stills are still continuing to distillate, and a group of alchemists are processing petals and collecting essential oils.

More than half of the petals in more than ten baskets have been used, and the rest are osmanthus and chrysanthemums. The petals have wilted very much, but it seems that there is no big problem with distilling essential oil, because the essential oil is still dripping from several distillation equipment.

"Mr. Marquis, these are the essential oils collected yesterday and today, a total of five bottles..."

Seeing Chen Xu come in, the laboratory manager, an old alchemist with white hair and fairy hair and fairy charm quickly came up and took Chen Xu to see the fruits of the labor that the group of people had worked hard for nearly two days.

Five small crystal glass bottles were used to hold reagents, and they were filled with transparent liquids of more or less different colors. They were tightly plugged with corks, and labels were also attached to the bottles. Three of them were golden-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-yellow-y

Vanilla does not actually refer to certain kinds of flowers and plants, but a general term for fragrant wild grasses. Many of them belong to herbs. Therefore, it was a material used by people to make medicine bags to repel mosquitoes. Therefore, the baskets of vanilla collected by the servants of the Hou Mansion of Qinghe was very complicated, including common mint, orchid, perilla, mugwort, and even many wild flowers, wild grasses and fruits that Chen Xu didn't know at all. However, these things were mixed together and several alchemists did not choose them. Instead, they chopped them together and put them in a distiller to refine them. Finally, they obtained a light brown essential oil of about one or two.

Chen Xu first opened the bottle of mixed vanilla essential oil and smelled it. He felt an extremely pleasant and comfortable smell rushing into his lungs. The smell was filled with the coolness of mint, the lightness of orchids, the lightness of perilla, and various rich spring seasons of mountain flowers. It seemed that he could see a field of blooming flowers in an instant.

"It's not bad, this vanilla is very good!" Chen Xu was amazed and quickly covered the vanilla essential oil, and then opened the osmanthus essential oil and chrysanthemum essential oil and sniffed it. It felt that the scent was not much different from the sachet smelled, but the taste was countless times pure and rich, as if he had sucked in a whole basket of petals, which was a bit fascinating.

"Mr. Marquis, you are really fantastic. You can actually think of using a distiller to extract the fragrance in the petals. But this bottle is too small, and it is not enough to mix water and drink it!" The Taoist priest like an old god stood beside Chen Xu and said with admiration.

"This is not something to drink, but it is used to spray it on your clothes to enhance the fragrance!" Chen Xu explained with a black line on his head.

"Uh!" The old Taoist priest was stunned for a long time and said stammeringly: "Marty, why do you spray it on your body to increase fragrance? Is it deodorizing?"

"Do you have a wife?" Chen Xu asked back.

"The old man pursues the way of immortality and refines medicine to seek immortality, but never marryes a wife!" The old Taoist priest said in confusion.

"That's right. You don't like women. You can't explain this clearly. Go and take the purified alcohol and distilled water, and then take the dropper and test tube. I will use it." Chen Xu curled his lips and refused to communicate with this old Taoist priest who pursues the way of heaven without a wife or a child.

When talking to a Taoist priest who doesn’t like women, it is obvious that he doesn’t have a pot of pee.

For the next half of the day, Chen Xu stayed in the chemistry laboratory.

By the afternoon, a group of alchemists had refined all the remaining baskets of petals, and obtained a total of five bottles of osmanthus essential oil, three bottles of chrysanthemum essential oil, and a bottle of vanilla essential oil. Each bottle was about one or two full, so all these essential oils were less than nine taels. At present, one pound of Daqin is sixteen taels, and one pound is only half a pound of later generations. In other words, more than ten baskets of petals were filled, and the total refined oil was less than one hundred and fifty grams.

Moreover, this is not purely essential oil, because the bottom of these essential oils is obviously divided into two layers, and some of them are water below. If they stand for a period of time, more water will probably be precipitated.

"Sure enough, there's so little essence!"

Chen Xu looked at the row of test tubes with different colors and light colors on the test tube rack and the large bottles of perfume that had been prepared on the table.

After most of the day of busy work and continuous tests with test tubes, Chen Xu made several bottles of perfumes that he felt could be used based on his own feelings.

It is natural to spray and apply essential oil directly, but it is too wasteful. Moreover, the essential oil evaporates very quickly and the fragrance is too strong, which can actually cause discomfort among some people. Moreover, after using alcohol to blend essential oils into perfume, the fragrance is light and it is easy to adhere to the surface of clothes and skin, forming a long-lasting light fragrance, which gives the kind of quiet elegance that Chinese people like, which is red sleeves and a faint fragrance.

After making a few bottles of perfume, there were some essential oils left. Chen Xu asked the laboratory manager to finish it.

"Mr. Marquis, do you still want the perfume in this test tube?" Several alchemists came up with a stubborn head.

"Why? Do you guys who don't want to marry and have children also want to go shopping in the garden and seduce the little ladies?" Chen Xu said with a smile.

"Hehe, there is no interesting thing in the garden to do experiments, it's just... it's just..." A middle-aged alchemist shrank his head and stopped talking.

"It's okay to say anything. If what you say is reasonable, I will give you these perfumes!" Chen Xu waved his hand.

"Mr. Marquis, we have been in the chemistry laboratory for more than half a year. Chemical experiments are indeed mysterious and interesting, but we have almost never studied anything in half a year. When chatting with a group of colleagues and drinking tea, we always feel embarrassed. These essential oils and perfumes are the first useful thing we have made with you. Although they are for women, they can at least be full of face. They can show off with many friends from the Taoist countries and let them see our research results..." A priest with black beard and black hair in his thirties mustered up the courage to speak out.

Chen Xu nodded after hearing this, "Yes, you do have to come up with some scientific research results for those Fang Daoists to see. Chemical experiments are not just a study that can only make bottles and jars all day, but also something that people cannot imagine. The process of refining essential oils to make perfume is a very classic chemical process, which can be used to process various different items. At present, it is essential oil for refining flowers, and then it can also study the essence of medicinal materials to make more effective and easy to drink preparations..."

"Hey, Master Hou's words make sense. This distilled preparation is similar to the ones we used to boil medicine and refine elixirs. We all need to get out the essence of the medicine!" A group of alchemists instantly showed a look of surprise as if they had discovered a new world.

"Well, you can conduct research on this matter on weekdays, such as extracting common drugs into potions or making them into powders with other items. You are all proficient in pharmacology, so it should not be difficult to understand. The difficult thing is how to take the essence and remove the dross and obtain the truly useful ingredients in the medicine. This matter is very important but also very complicated. So you can experiment slowly. Three years, five years or even eight years and ten years. As long as you can succeed, your name will be left in the history books that have been passed down for thousands of years in China in the future. As the pioneers of this new drug, you will definitely become a famous medical expert who will remember the inheritance of future generations and will be remembered forever..."

Chen Xu said a few words, and suddenly the stimulating eyes of a group of alchemists were red, and they all started to breathe with red faces and thick necks. They clenched their fists like bulls in heat and stared at each other. Chen Xu felt that if a red cloth was thrown out, these alchemists would instantly collapse the laboratory.

"By the way, you'd better go and communicate with Doctor Xu from the health center. They now have several pharmaceutical factories that make various pills and powders. As long as you develop them successfully, cooperation with the pharmaceutical factory will definitely be a big project to make money. The perfumes in the test tube will be given to you, which is a reward for you in the past two days. By the way, the production method must not be disclosed..."

Chen Xu put a few bottles of made perfume into his carry-on bag and said.
Chapter completed!
