Li Yanqing was as if he had a treasure, so he hurriedly ran into the store with the box. Li Daqi was puzzled and followed behind and asked, "Yanqing, do you want to make balm too?"

The balm in the Song Dynasty was made into a ball with soap beans, rubbed with flour and spices, and made into a ball. The size of an orange is snow-white as white as fat, and looks very attractive. It is also called a balm ball. It is not expensive. It costs twenty cents per person and can be used to take a bath and wash your face.

But this kind of balm is not affordable for ordinary people. It is mainly because the flour is insoluble in water. A balm cannot be used several times, and it is only used by the imperial palace or powerful people. It is either a high-end place such as alum building. Ordinary people directly wash their faces with clean water, or mash the soapcorn and wash their faces and take a bath. It is more alkaline.

If you want to let balm enter ordinary people's homes, you should make soap. Li Yanqing would make soap when he was in middle school, then grind the soap more delicately, and add spices and colors to make soap of various colors.

Vegetable oil and animal oil are fine for making soap, but Li Yanqing decided to use animal oil because he wanted another by-product of soap, that is, glycerin, which is necessary for making good rouge.

Zhang Gu Lao Rouge has oil in the formula, because they can't extract glycerin yet. Rouge made with glycerin is much better than using oil directly, and their rouge will be next level.

"Yanqing, balm is relatively simple to make and the profit is not high. Just buy ready-made ones, and you don't have to make them yourself."

Li Yanqing shook his head, "The balm I want to make is not the same as the balm sold outside. Zhang Gu's balm is used at most twice. The balm I want to make can be used for at least ten days and half a month, or even longer, so every household can afford it."

“What should I do?”

Li Yanqing smiled mysteriously, "I have basically all the ingredients. I will make it for you tonight."

At night, in the room where the perfume was made, his father Li Daqi sat on a chair, and there were also magpie, shopkeeper Wu and Tiezhu. The four of them opened their eyes wide and watched Li Yanqing's operation.

The seaweed ash bought by Li Yanqing is just burned in a coarse manner and needs to be burned repeatedly to fully react with the air, and finally form some off-white ash, which is baking soda.

It is very important to use seaweed. If you use wood ash, you can also make it, but the soap made is much less water-soluble. You must use sea plants to burn it into baking soda.

The baking soda has been dissolved in water first, filtered repeatedly, and filtered the residue to form a milky white liquid. Li Yanqing poured the soda water into a large pottery jar.

At this time, the fish oil had been heated and turned into a transparent liquid. Li Yanqing slowly injected the fish oil into the pot. He handed a wooden stick to Tiezhu and smiled: "Stir constantly, stir for half an hour!"

"What will the little official become?" Xi Magpie couldn't help but ask in a low voice.

"It will become a kind of milk-like thing."

Li Daqi couldn't help but say, "The cost of doing this is greater than that of ordinary balm!"

"But it is also durable. I believe everyone will like our balm after using it."

In less than an hour, the saponification reaction was completed. A ball of condensed milk-like soap base appeared in the large jar. Li Yanqing filtered out the water and glycerin, added spices to the soap base and stirred well, then poured it into a bamboo tube and sealed it with a dry towel.

"It will naturally solidify slowly after two days. Take it out and put it in a ventilated place to hang it for a month, and the balm will be made."

"Is that simple?" Everyone was stunned.

Li Yanqing smiled and nodded, "It's actually that simple!"

He pointed to the filtered glycerine and waterway: "Distillate the water in it by distillation, and the remaining oil will be used to replace the oil used for rouge. The effect will be better. You can try it."

At this time, Li Daqi pulled his son aside and whispered: "Now, whether it is rouge or perfume, plus this balm, the sales volume is very high. It may not work if you only use two or three people to make it, but the technology and formula cannot be leaked. I discussed it with Manager Wu. We thought it could be divided into several links, and each link is made by different people, so that other rouge shops can't learn it. What do you think?"

Li Yanqing nodded, "This method is good, but I think the key is the brand of Baoyanzhai. You must keep it as your life. Baoyanzhai's things cannot be sold to other rouge shops, but can only be sold by Baoyanzhai's own rouge shops. In the future, if the business grows bigger, except for the capital, each other state can only open one at most, and it must be opened in the best place."

"Shopkeeper Wu's idea is the same as you. If Baoyanzhai does a good job this year, I will give him half of the part and let him continue to work with me with peace of mind."

At this time, Tiezhu asked, "All done, what should I do next?"

Li Yanqing walked up and smiled and said, "It's still early now. I'll give you another demonstration. Everyone should remember it well. In the future, you can add various flower juices, wine, green tea oil, and rice oil to make balsams of various colors and flavors. Then package them in Baoyanzhai's small nanmu box, and one box can be sold for fifty cents."

.........

Half a month has passed, and Bianjing has begun to get hotter day by day. It has been June. The red-colored Wang Family Rouge Shop on Yu Street has been still blocked, and there is no news about its new owner.

But many famous businesses have turned their attention to this one-acre shop, which is the best site in Yu Street. The famous Alum Tower is across the street. Except for a few shops, they basically make money every day.

The Bianjing style emphasizes luxury and fashion, and both men and women are proud of shopping on Yujie, which has led to Yujie becoming a synonym for the greatness of the Song Dynasty.

Li Yanqing also deeply understands this. For example, the products of Wangjia Rouge Shop dyed red, whether they are rouge or perfume, foundation or ink, are of medium quality.

But the rouge in this store can be sold at a high price and the business is booming. In just two years, it became the second largest rouge shop in Beijing after Zhang Gu. The fundamental reason is that it is located in Yujie. Its products are marked by Yujie's products and immediately become high-end products in people's eyes.

It was the unique commercial location of Yujie that caused a store to show signs of transfer, and countless merchants and backends began to compete fiercely behind the scenes.

Now that the Wang family's rouge shop has been sealed off, how can the powerful people in Bianjing not be eyeed?

In the afternoon, an unexpected guest came to Li Yanqing's dormitory. The guest was the fat man Zheng Rongtai. This was the first time Li Yanqing saw this fat brother after returning from Jiangnan. But to Li Yanqing's surprise, Zheng Rongtai really became thinner. Although he was still a fat man, his adjectives could already be used to replace fat. He lost at least thirty or forty kilograms.

"Old Li, how did my new robe come about?"

Zheng Rongtai turned around gracefully in front of Li Yanqing, with a bit of Zhu Bajie's demeanor of jumping into Swan Lake. Li Yanqing curled his lips. This is not to show off his clothes, but to show off his figure.

"Brother Fat seems to have lost a lot of weight!"

Zheng Rongtai's eyes were slit in a slit, "I used to have at least 220 kilograms, but now there are only 180 kilograms left. If I can lose another 20 kilograms, I can ride onto the battlefield."

"How did you lose the fat meat?" Li Yanqing a little forgot that he had given Zheng Rongtai the idea.

Zheng Rongtai blinked the green beans' eyes, "Did you forget it? You taught me that I slap in the water for two hours every day, drinking iced honey and winter melon juice, I will do it according to the method you taught, and I will lose weight like this."

Li Yanqing was both angry and funny. When did he make him and the beauty slap, he even added honey to the winter melon juice, and said it seriously.

"I've already appreciated your figure. Is there anything else?"

"Of course there is, I'll send you an invitation."

Zheng Rongtai handed an invitation to Li Yanqing and said, "My grandfather's 70th birthday is invited to invite thousands of celebrities in Bianjing. I have three indicators, and I will invite you one of them."

"Oh! When?"

"The afternoon after tomorrow, the location is Alum Tower, and our family will book Alum Tower for the rest of the day."

Li Yanqing suddenly had an enlightenment in his heart. The Zheng family has been acting low-key, and then he actually treated a guest at the Alum Tower. Isn’t it a sensation in the whole city? Does this mean that the Zheng family is going from behind the scenes to the front desk?

"How is it, no problem!"

Li Yanqing suddenly thought, isn’t this a great opportunity to promote soap? He immediately said with great interest: “Don’t worry! I will definitely arrive on time.”
