Finding a napkin, and wiping the water stains from the corner of his mouth, Todd's expression was like swallowing a fly: "Wait!

The young man repeated: "We steal the manure from which we make nitrate to make perfume......

After careful questioning, Todd finally understood the cause and effect of the matter.

This young man, Cleaver, was one of the first students to escape from Taylor. During the time he lived in Twilight City, he had to study at the academy, go to the library to print books, and consider the cost of daily food and lodging. Over time, I am short on money, and the situation of eating the last meal but not the next meal has happened from time to time. So, he got a job in a nitrate factory run by the elder Aiden.

The young man is smart and diligent, and the hard work of the manure fermentation tank is avoided by others, but he takes the initiative to undertake it and does it in an orderly manner.

Seeing this, the elder Aiden took it to heart, and gradually promoted Clive to the position of supervisor, and gave him great authority. Unfortunately, it didn't take long for a subordinate to tell the old craftsman that Cleaver, together with the monk who kept accounts, had stolen the raw materials of the nitrate factory......

Todd glanced at the young man kneeling on the ground and asked, "What's going on with the perfume?"

Clive glanced at the trembling 'accomplice' beside him and sighed, "Your Majesty, that's the case. Once, after the manure was fermented, I accidentally spilled some of the leftovers while transporting them. I rinsed the floor with hot water a few times, and I didn't care about it. At noon the next day, under the sun, there were some crystals in the shape of pale yellow scales on the washed ground. I crouched down and sniffed it, and it was a strange smell. It's not a smell, it's a bit like the smell of spices after a long time......"

When Todd heard this, his stomach topped over, and he sneered: It's really a shame that you can do such a thing as smelling feces......

Later, with the idea of trying it out, I purified these light yellow crystals by evaporation filtration, and diluted them with ethanol at a ratio of one to one. Clive gestured with his hand and said, "I went to the market and looked, a bottle of flower essential oil from the Southern Empire, a bottle the size of a big finger, can be sold for 280 silver moons. And this perfume made from feces, the taste is a bit similar to flower essential oil, and the cost is not even 3 copper stars, so I secretly made a few bottles, saying that it was a perfume from the south, and sold it. ”

Todd's eyes grew brighter as he listened to Cleaver's story.

Using feces to make perfume is really a breakthrough in the world, but from the perspective of chemical principles and molecular chains, it is a completely reasonable thing.

Medieval flower essential oil is a substance called methyl dihydrojasmonate hedion. It is a colorless or light yellow transparent liquid that is a natural aromatic chemical that is mainly derived from large flowers such as jasmine or rosemary. It is cumbersome to produce and refine, and the product conversion rate is low, and the price is very expensive. In medieval Europe, the royal families of some small countries even passed down a small bottle of flower essential oil as a family heirloom from generation to generation, which is a historical record and not a fabrication at all. Even in modern society, methyl dihydrojasmonate is a fixed chemical in high-end perfumes, and it is often used to prepare formulas such as jasmine, lily of the valley, and wanxiang jade, which can make the fragrance produce an elegant, realistic natural floral fragrance.

After talking about high-end goods, let's talk about "big dung perfume".

There is a chemical in the feces called "skatole", and its chemical name is "3-methylindole" (English name: 3-methylindole). It is a white or slightly brown crystal, sensitive to light, soluble in hot water (above 67 °C), ethanol, benzene, chloroform and ether. At high concentrations, this substance has a pungent odor similar to "foul odor", but when fully diluted, it has a fresh floral smell, which is an important raw material for the preparation of jasmine type. It can generate derivatives such as indole and quinoline, and is used as flavors such as beverages, candies, and chewing gum. (That's right, the drinks you drink and the gum you eat contain the chemicals in this...... ）

The most interesting thing is that as long as the "skatoxin" is diluted to a certain extent, and additives such as lemon, bergamo pear, citrus, lavender and other additives are added, the resulting product will indeed be very similar to flower essential oil. However, the production cost of the two is nearly 10,000 times different.

Thinking of this, Todd looked at the young student in front of him, and something flashed through his mind.

Artificial perfumes, scholar factions, financial crisis, scientific research and development...... There may be a way to connect these seemingly unrelated things together to alleviate or even solve a series of problems that the Twilight Kingdom is currently experiencing.

Todd motioned for the attendants to bring their chairs, and said that the three old Aidens should sit down and talk.

Looking at their anxious expressions, Todd turned to Cleaver and asked, "Tell me, are the students of the academy as lacking in living expenses as you are?" If I remember correctly, the Twilight Academy should have given some subsidies to all teachers and students. ”

The young student whispered, "Your Majesty, there are indeed some subsidies. But the food and lodging in Twilight City are getting more and more expensive, and in the past, ten Bronze Stars could buy a pound of wheat flour, but now they can only buy a pound of bran. Most of us who don't have financial resources share other people's houses, and with the demand of residents and the influx of immigrants, the rents of homes are getting higher and higher, and many people I know have had to leave their houses and sleep in classes at the academy or even on benches in the park. ”

Todd shook his head helplessly when he heard these words. At the beginning, he only ordered the payment of room and board subsidies according to the standard, but forgot about the rise in prices. But on second thought, this incident also gave him an opportunity, an opportunity to weaken the influence of the Jade Society from within.

"Because they live in poverty, they steal. I won't pursue the matter of nitrate making materials anymore. The king's promise made the three people sitting obviously relieved, and Todd's words changed: "But this is not the way to go on after all, I will take some funds from the 'Twilight Mutual Aid Society' to set up a workshop to produce this perfume." ”

"Cleaver. ”

Hearing the king's name be called, the young man's body shook and straightened his back.

Todd thought for a moment and said, "The funds and locations are prepared by the kingdom, and I plan to let you be in charge of manpower recruitment, technical research and operation management." In addition, for every bottle of perfume sold, 20% of the net profit generated will be paid to your team. ”

Clive was stunned, and the king not only did not punish himself, but also paid for the construction of a perfume workshop to be taken care of by himself, and promised to give up 20% of the profits from the product. In his opinion, all this is simply incredible, and it is really a godsend!

Seeing the young man's grateful expression, Todd took a sip of tea from his cup and continued, "The Kingdom of Twilight will soon introduce a law called 'Patent Law'. As long as the registration and filing of any person's invention or creation is completed, the royal family will grant the inventor a "royal patent certificate". Anyone who uses the patented technology for product production or research and development must pay a certain amount of coins as a "royalty". The inventor will enjoy 80% of this income, and the royal family will enjoy the remaining 20%. ”
