Lin Wanrong still cared a lot about Qin Xian 'er's words. Xiao Qingxuan was the closest person to him in this world. He didn't want her to be in any danger.
He had to think of a good solution. If it didn't work out, he would take advantage of the chaos to get rid of Qin Xian 'er. I don't believe that even if you have unparalleled martial arts, you can't defeat my two golden spears. Hehe.
After returning to the Xiao Family's nest, he couldn't fall asleep for a long time. Xiao Qingxuan's image kept appearing in his mind. Now it seemed that Xiao Qingxuan's family was either rich or respectable. In order to reduce the resistance between them, he had to further strengthen his own strength.
His martial arts were not bad. With the poison needles and the flintlock, even if he met Dongfang Bubai, he could still fight. At present, the Food for Immortals was doing very well. It was making money every day. The Xiao Family's underwear and perfume business were also very successful. Especially the perfume business, it was extremely profitable.
Unfortunately, due to production problems, the production of perfume could not increase for the time being. There was money to be spent, but he couldn't earn it. He was anxious. Moreover, the perfume business seemed to be too weak. He should find other related businesses and gradually improve the product line. With more varieties, there would be more opportunities to earn money.
In fact, when the perfume business was born, he had a plan in his heart. Since he was making perfume, why not make other daily necessities? With perfume, he could also make soap.
The raw materials for soap were very simple. He had learned about it in middle school chemistry textbooks. At that time, Lin Wanrong had even done a class experiment. Adding caustic soda to oil and heating it at high temperature, it was done. Moreover, the process was not complicated, which was conducive to mass production.
There were also two types of soap, laundry soap and scented soap. The process of laundry soap was rough. It could be extracted directly from animal fat and caustic soda. In order to save costs, one could also add 10% to 20% rosin. As for scented soap, the principle was the same. It was just that the process was more complicated. It needed to be made from vegetable fat and caustic soda. After purification, it was made with fragrance.
Essence was naturally not a problem. Anyway, there was a lot of braid residue left from brewing perfume, which could be reused.
With the experience of perfume, Lin Wanrong has gained a lot of confidence. As long as this soap is made, it will become a profiteering product comparable to perfume. Just the perfume and restaurant alone were enough, but with the soap industry, he suddenly had three golden roosters that could lay eggs, and two of them were his exclusive property. It would be hard for him not to prosper.
With this thought in mind, he became excited and his heart itched. These two skills of mine are purely exclusive inventions. If the Chinese Academy of Sciences existed in this era, I would have been the director long ago.
He also wanted to get some shampoo and facial cleanser, but unfortunately, he didn't know much about these things. What I regret even more is that I didn't research the ingredients of Viagra properly. If I had the patent for Viagra, I could make hundreds of small blue pills and sell them to the Emperor, nobles, and ministers. There would be no justice in the world if I didn't die from it.
That night, his heart was in an uproar, cheering for his great invention, and he did not sleep the whole night. The next morning, he got up early and hurried outside.
When he walked to the middle of the courtyard, he saw Grand Mistress gracefully coming in from outside. It turned out that she stayed with Second Miss at Xixia Temple yesterday. The two sisters talked all night and just came back this morning.
Seeing Lin San walk out with a smile on his face, without even looking at her, Xiao Yuruo stopped him and said, "Lin San, what are you going to do?"
Lin Wanrong stopped walking. When he saw who it was, he smiled and said, "Oh, it's Grand Mistress. I'm going to buy lard."
Xiao Yuruo looked at him and said, "You're not a chef, why do you want to buy lard?"
Lin Wanrong smiled and said, "I can't reveal the secrets of heaven."
Seeing his mysterious look, the Eldest Young Miss thought to herself, "This guy, I'm afraid he's up to something again." Having seen the power of the perfume, she was also very curious about him. She said, "I got up early in the morning and have nothing to do, so I'll go with you."
No way, Grand Mistress is going to buy lard with me? This is not a good thing to say. Lin Wanrong said with a bitter face, "Grand Mistress, don't make things difficult for me. You're an important person, how can you fool around with me? How's the progress of the perfume promotion? "
Xiao Yuruo nodded and said, "The promotion is very good. By the way, we're going to the Jinling Poetry Club the day after tomorrow. You should go with me and see more big scenes. Maybe it will be useful in the future. "
Lin Wanrong understood. This is Grand Mistress training me. She probably wants me to be the backbone and elite of the Xiao Family. Hehe, this is interesting.
He smiled humbly and said, "Since it's Grand Mistress's order, I will naturally do it. But what is the Jinling Poetry Club? "
Grand Mistress nodded and thought to herself, "If you have this humble attitude every day, I won't always look at you."
"The Jinling Poetry Club is the largest reading place in Jinling. There are many famous talents gathered there. If the perfume is successfully promoted among them, it will be a great success."
Lin Wanrong nodded. He understood this logic. Wasn't it just the effect of a celebrity? The talented women of this era were equivalent to the female celebrities in his previous life. If he found a beautiful and talented woman and told them that they would be healthier after washing, it would be hard not to become famous in China.
As he was fantasizing, he heard Grand Mistress continue, "The Jinling Poetry Club has the largest network of people in Jinling. Not only is there the number one talent of Jinling, Hou Yuebai, the number one talent of Yangzhou, Yu Wenpo, but also the number one talent of Jinling, Luo Ning, and many of her subordinates. If we can find an opportunity among them, our perfume will be completely established in Jinling."
The Eldest Miss seemed to be in a good mood today. She was no longer as impatient as she was in the past. She spared no effort in introducing the business to him. It seemed that she really wanted to cultivate him into the backbone of the Xiao family.
Lin Wanrong curled his lips in disdain. After all this talk, it turned out that the Jinling Poetry Club was supported by Luo Ning and her subordinates. However, Grand Mistress had chosen the route of the upper class very well. It was a gathering place for some talented young ladies from official families, so it should be the focus of the business.
After talking for a while, Grand Mistress saw that he looked relaxed. She didn't know how much he had listened, so she could only secretly snort and let him go.
Lin Wanrong was famous for being lazy. He didn't need to personally buy lard. He was now a high-ranking servant of the Xiao Family. He was the favorite of the ladies. Even the two stewards were inferior to him. Now that his value had skyrocketed, if he didn't know how to make use of it, he wouldn't be the omnipotent Brother Lin San in the Xiao Family.
He went to pick a young waiter. It was the one he and his Young Cousin went to the brothel and got a tael of silver as a reward for flattering the Young Master. His name was Sande.
"I said, Sande …" Lin Wanrong said.
The young waiter hurriedly cupped his hands and said, "Third Brother, you don't have to be so polite. You are Third Brother. How could I dare to use your name? From now on, I am called Si De. "
F * ck, look at this bootlicking. He even knew how to avoid taboo. Otherwise, how could he say that this kid had a bright future. This feeling of being a fox exploiting the tiger's might was very comfortable. He nodded and said, "I said, Si De, go to the butcher's shop and buy me four catties of lard. On the way, help me get some pure caustic soda. Then call Uncle Fu back. Tell him that I have something to discuss with him. "
Having someone to run errands was really cool. In one breath, he sent three tasks. Lin Wanrong only needed to move his mouth and Si De did it neatly. When Uncle Fu came back, he saw Lin Wanrong directing Si De to make a fierce fire in the stove. The white lard was rolling in the boiling water, and the air was filled with a faint fishy smell.
"Uncle Fu, you came back at just the right time." Seeing that there was labor joining in, Lin Wanrong was not going to be polite. It didn't matter if you were old or young, as long as you could do the work.
He took a large piece of fine sand cloth that had been prepared a long time ago and ordered in an orderly manner, "Uncle Fu, you are experienced. In a moment, after Si De cleans the surface of the dirt, you use this cloth to filter out the grease and then wash it."
Uncle Fu said strangely, "Lin San, what are you doing now?" It had to be said that Uncle Fu and Chang Bo really admired Lin San. Although this kid was only a dabbler in floral art and machinery, he often had some strange ideas that made the two of them slap the table and praise him.
Naturally, Lin Wanrong would not say it out loud. He laughed and said, "Uncle Fu, we are old friends. Don't you believe me?"
Uncle Fu snorted. You kid, you don't have the thought of respecting the old and loving the young. However, he still trusted Lin San very much. Seeing that Lin San did not seem to be joking, he did as he said.
Lin Wanrong took his special pencil and kept writing on the paper, but it was all symbols that the two of them could not understand. After a long time, he put down the pencil and said, "Dear chemistry teacher, I will always love you."
He was in high spirits. He let Uncle Fu pour all the washed fat into the pot and cooked it again.
The temperature of the fire was getting higher and higher. Si De followed Lin Wanrong's instructions and kept stirring. Lin Wanrong took the sodium carbonate that was one-third of the fat and threw it into the pot.
After boiling for about half an hour, he let Si De pour a large amount of coarse salt into the pot and stirred it evenly. Those who studied chemistry knew that this thing was called "salting out."
About half an hour later, Uncle Fu and Si De were surprised to see that in the pot that was boiling lard, a layer of light yellow ointment gradually floated on the surface.
Lin Wanrong was overjoyed. This is soap. I am really a genius. Dear chemistry teacher, you should be proud of me. I will always remember your teachings: if you learn mathematics, physics, and chemistry well, you will not be afraid to go anywhere in the world.
This was actually a very simple chemical experiment. Under high temperature conditions with the presence of alkali, oil was hydrolyzed to produce high-grade fatty acid salts and glycerin. Fatty acid salts were commonly used as soap. Things like glycerin, with nitric acid, could be made into trinitroglycerin vinegar, which was nitroammonia explosives. Because soap did not dissolve in thick salt water, and glycerin had a high solubility in salt water, the soap and glycerin could be separated by adding salt.
Lin Wanrong was happy for a while, then he let Si De use a scraper to scrape the light yellow ointment into a large wooden box. When it slowly cooled, it became a large piece of soap.
As for the by-product of glycerin, Lin Wanrong was still itching. With this thing, he could make a few bombs to play with. But he also knew the danger. This nitroammonia explosives were extremely unstable and could easily explode with a little vibration. He hesitated for a long time and temporarily gave up this plan. It was too dangerous. His little life was still more important.
Lin Wanrong looked at the large piece of soap, but his heart was calculating. Using this animal oil to make soap, how much would it cost?
This four catties of lard was about the cost of eight silver coins. This soap could be made into about thirty to forty pieces of soap the size of a small fist. A piece of soap would cost at least eight silver coins. That would be a profit of thirty to forty taels of silver. It was too f * cking impressive. Moreover, this lard was only an experimental product, so the cost was on the high side. He could also use other animal oil or vegetable oil to further reduce the cost.
After waiting for two hours, the soap finally cooled down. He let Si De bring a basin of water and threw the dirty clothes into the basin to soak. Then he dug out a small piece of soap and gently brushed the clothes a few times. After soaking in the water, the stains disappeared without a trace.
Uncle Fu was dumbfounded, "Lin San, what is this thing? So magical? "
Lin Wanrong laughed, "Uncle Fu, you have a feast for your eyes today. This thing is called soap. I invented it myself. "
Uncle Fu sighed, "Lin San, with this thing, it will save those young ladies a lot of effort. They really have to thank you."
Lin Wanrong laughed, "Uncle Fu, look at what you are saying. In fact, I have always wanted to benefit millions of women and set a new social trend. But every time I think about how far I have to go to achieve this goal, I feel guilty. "
Uncle Fu directly ignored his words. He carefully rubbed the newly formed soap. It was thin and smooth. He felt strange. How could this thing be so magical?
This soap was only the crudest kind of laundry soap. To make soap, the principle was exactly the same. It was just that the fat had to be replaced with vegetable oil, such as coconut oil or tung seed oil. After a few more steps of purification, some colors and spices were added, and then the soap could be made. Lin Wanrong had always felt that it was a waste to use the flower braid powder to make the perfume. Now, he could finally put it to good use.
He followed this method and did another experiment. This time, he used tung seed oil and sprinkled some squeezed flower braid powder. Lin Wancha valued the soap even more. She didn't let Side do it. She did it herself and put the paste into another box.
When the soap slowly cooled, Uncle Fu and Side's eyes were wide open. The soap powder had a light yellow tint to it, and the color was very beautiful. There was also a faint flower braid fragrance in the air. Just a sniff was enough to make people fall in love with it.
Success, he finally succeeded. Lin Wanrong's heart was filled with excitement. He couldn't help but look up to the sky and laugh. All the beauties in the world, just wait and use my, Brother Lin San's, great invention. I will definitely make you more beautiful, more fragrant, and more fragrant.
These two experiments took two whole days, but it was much easier and simpler than making the perfume that day. Uncle Fu and Side followed beside Lin Wanrong and watched the birth of the miracle with their own eyes.
If the perfume was unintentional by Lin Wanrong, then the soap was intentional. Benefit the people of the world? Lin Wanrong didn't have this kind of idea. Making money was the real thing.
Soap was a new product, so it naturally had to be of the upper class. The price had to be set high, and the profits would certainly not be lower than the perfume. With the monopoly of underwear, perfume, soap, and especially the latter two, wouldn't the world's money come rolling in? In the future, when I make more medicinal soap, I will make it into a chemical industry. Damn, let's see who dares to compete with me. At this moment, he had a feeling that he was successful and could look down on the world.
It was already time to light the lamp. Uncle Fu had really broadened his horizons these two days. He sighed for a long time before saying, "Lin San, do you want to let the Grand Mistress take a look at this thing?"
Lin Wanrong was also thinking about this problem. The perfume was handed over to the Xiao Family to manage. On one hand, it was because of Xiao Yushuang's face. On the other hand, it was because the Xiao Family had a very perfect marketing network. Although Lin Wanrong had the technology and products, marketing was what he lacked the most. If he had to spend energy to rebuild it, he didn't have that much money and energy. Letting the Xiao Family be the sole agent was also a good way. He had seen this kind of model many times in his previous life.
He thought about it and said to Uncle Fu, "You can let the Grand Mistress take a look. Alas, I'm such a failure. I'm always being exploited by her."
The Grand Mistress's footsteps were much faster than Lin Wanrong had imagined. Probably in her eyes, Uncle Fu was an honest man and wouldn't lie. Therefore, she didn't hesitate to believe the facts that Uncle Fu had seen with his own eyes. If Lin San went to report, it would be very good for the Grand Mistress to believe one out of ten of his words.
Xiao Yuruo entered the house and saw Lin Wanrong looking at her with a smile. Her face turned red and she said, "You, are you always so frivolous?" Lin Wanrong asked.
Lin Wanrong laughed and said, "Grand Mistress, I've never been so serious."
The Grand Mistress glanced at him and snorted softly. Her eyes fell on the things behind him.
Is this the thing called soap? Xiao Yuruo looked curiously at the two big pieces of soap in front of her. The workmanship wasn't very fine and was a little rough. However, it was smooth and smooth to the touch. Especially that fragrant soap. It was a light pink color with a hint of fragrance. She liked it a little at first sight.
"Lin San, did you really make this?" The Grand Mistress's excited voice was a little shaky.
