When Li Jian came back, Li Hao had already used toner to adsorb impurities in the oil. Although the oil at this time was not as translucent as normal oil, it looked like there was no big problem.

So I took the plant ash that Li Jian had given me, and added a tank of water, threw the plant ash in, boiled it, and stirred it. Of course, Li Jian was in charge of the stirring, and Li Hao was there to guide me. After stirring for a while, the

Screen out the impurities floating on the surface, and then wait for the impurities to settle, then remove the clean alkaline water.

Then put the pot back in to heat some of the alkaline water, and at the same time pour the oil with the impurities removed into the pot, and then ask Li Jian to start stirring thoroughly. At high temperature, the alkali reacts with the fat in a saponification reaction, allowing the fat to slowly condense into a viscous solution

.When you see that there is still grease floating, add alkaline water little by little and repeat several times until all the grease disappears.

At this time, there is only a translucent solution left in the pot. Add salt grains to the pot to perform the salting out reaction. At this time, the light yellow precipitate begins to slowly float to the top of the solution. At this time, the temperature is slowly lowered and the precipitation is solidified.

, they shoveled it down and put it into a prepared wooden box, pressed it into square blocks, and then put them out one by one to dry slowly in the shade.

At this time, looking at the formed soap, Li Hao felt proud, feeling that he could really change history and use technology to change destiny.

Just when Li Hao was still so proud, Li Jian was really tired. After all, he just kept stirring for more than an hour. If it wasn't so important as Li Hao said earlier, he would be afraid of missing something.

He had long wanted to ask Li Hao what he was doing and if he could stop. Mrs. Wei next to her felt sorry for her husband when she saw it. She quickly brought a bowl of water and gave it to Li Jian to drink, and asked him to sit down and rest. Then she pointed to the ground.

The soap asked Li Hao: "What are you doing? It's made of carbon, flour and salt."

In fact, when she was just making it, Mrs. Wei saw Li Hao throwing flour and salt into the pot and wanted to stop. This was a wasteful behavior. She only restrained herself when she saw that it was rare for a child to do something so seriously.

I didn’t ask until now, but I also made up my mind. If this little thing is unreliable, I won’t listen to Li Hao next time.

However, Li Hao didn't pay attention to anything else at this time. He just stared at the soap that was gradually drying, like looking at a sparkling gold ingot. However, he still replied: "Mom, don't you usually use soap locust for laundry? The soap on your clothes

Is it difficult to clean dirty things? This soap is different. You need to wet the soap and rub it twice, and then rub it gently. The dirty things on the clothes can be cleaned. It is easier to use than soap locust.

More than a hundred times."

After hearing this, Mr. Wei looked unbelieving and said, "It's really so good, and you've never used it. How do you know? And where did you learn this from? Did you read it from a book?"

Li Hao said: "Of course, a scholar can know the affairs of the world without going out." After saying this, he raised his head arrogantly. Then he continued: "After it is completely dry, mother will know if you try it directly. Come in then.

When we go to the city, we can take the soap with us and sell it in the market first. As long as we build a reputation in the front, sales will naturally be no problem later. Whether we make it ourselves and sell it or cooperate with others, as long as we put the formula

If you seize it, you will be rich for generations. And it is not just soap for washing clothes, but also soap for body cleansing. It is also an inheritance that can be passed down forever."

After hearing this, Mrs. Wei muttered: "It's a good saying that a scholar can know the affairs of the world without going out. I haven't heard anyone say it before. Maybe you just read it from the book."

After listening to this, Li Hao suddenly felt helpless and said: "Mother, have you misunderstood the point? The point is that everything here is money."

At this time, Mrs. Wei said with sincerity: "Since you have the ability to study and manage the world, you rely on fame and knowledge to settle down in the world. Although our family is poor, we have never starved you or frozen you. You

You can't put your mind on the skills of money merchants, scholars, farmers, industry and commerce, and simple merchants are just humble businesses after all. If you can really be named in the gold medal one day, then you will be the lintel of your family, and you will be the real family property, do you understand."

After hearing this, Li Hao actually didn't take it seriously, because he knew that whether he was taking the imperial examination or doing business, he just wanted to live a more comfortable life. Therefore, the imperial examination or doing business were only means after all. Now it is because the road to the imperial examination can bring

If there is a better prospect, he will naturally work hard. But if there is a businessman's skill that can make his life better, he will naturally do it. Of course, he will not argue with the Wei family, after all, this is a millionaire.

They are all of inferior quality, except for the era of high-level education.

So she pretended to be educated, and Mrs. Wei didn't say anything when she saw this.

After waiting for almost an hour, all the soap was basically dry. Li Hao touched it with his hands and found no problem, so he got up and got some clothes, put them somewhere and stepped on them a few times, and then deliberately put wet shoes on the clothes.

Rub it on for a few times. Then he brings the dirty clothes to Wei and asks Wei to try washing them with soap.

Wei took the clothes with a doubtful face, filled a wooden basin with some water, and put the clothes in. Then she picked up the soap, wiped it up, and rubbed it gently, and saw a lot of white bubbles popping up.

, put it in water and rubbed it, and the stain was gone. This shocked Ms. Wei. She had never thought that this soap was so easy to use. She immediately understood why her son said it was a huge wealth.

, if there is soap in the future, who will be willing to use soap locust?

Wei immediately began to calculate the cost of this item in her mind. If she really wanted to do it later, she would definitely not have to use oil, but would have to buy oil. Now a pound of oil costs 120 Wen. According to the big pot of oil just now, it is about 5 pounds.

About 260 pieces of soap were made. If other costs are added, even if the cost is 800 Wen, if each soap sells for 10 Wen, it is equivalent to a cost of 3 Wen, and each soap can earn 7 Wen. And this

Since the items were frequently used, they must have been sold in large quantities. Thinking about it, Mr. Wei couldn't help but laugh.

Li Jian also curiously came over from the side, took the soap from Wei's hand, and tried it. Then after trying it, he took it in his hand and looked through it, watching what he had made step by step, slowly starting from the oil.

He has become like this now, with doubts all over his face.

At this time, Mrs. Wei saw it, reached out and took it over. She said, "Don't waste things. These will be packed up later. One day, take a few pieces and go to the county town to try selling them." At this time, Mrs. Wei thought.

After thinking for a while, he asked Li Hao: "How can you price this soap appropriately?"

Li Hao had roughly made the calculation at this time and said: "I roughly estimated that the cost of the raw materials is roughly 3 cents, but the labor cost must also be considered. The initial quantity of this thing is small, so my father can make it himself. But if

If you want to do it in large quantities, you will have to recruit people, and the labor costs will have to be paid at that time. In addition, you can't just set up stalls to sell. If you really want to do it, you will have to rent shops in the city. All of these will have to be taken into consideration.

So the price cannot be set too low, otherwise it will always be troublesome to raise the price later.”

Of course, there is another reason. My family's soap business can only be sold in the city of Yangzhou. I want to take the imperial examination, so naturally I can't take care of the business myself. My parents have never been exposed to this since they were young. If they want to make it big then,

, you must cooperate with others. It is easier to set a higher price and give people a profit share later. You cannot let people know the cost all at once, so how can you make money?

Li Hao thought for a while and said: "After all, soap belongs to people from middle-class families and above. If the family is not rich, even if the soap is good, they probably won't change it. As for the price, it's better to order 20 yuan a piece and just press

Calculated as two yuan a month. For a middle-class family, as long as it is easy to use and spends an extra 40 yuan a month, they probably don’t care. When he goes back to the market next time, my father can bring the cloth and try it out for himself.

Show it to others and let others see the effect, and then people will naturally buy it. As long as the reputation spreads, and you find some people to sell it on the streets, you will naturally have no worries about not being able to sell it."

Li Hao suddenly thought about it and said: "By the way, we can also make a special mold and mark it, so that each piece of soap can have our special mark, so that everyone knows that this soap is

What we do as a family can only be done by us. As long as more people know about it, our reputation will be greater, and there will be no shortage of business in the future. However, it is best to find someone to cooperate with us. We don’t have the manpower to begin with.

, if we sell too much, it will be difficult to find production and sales manpower. Secondly, if we make it ourselves, no matter how good it is, it will be difficult to sell it in Yangzhou. Rather than letting others make the money, it is better to find someone we can trust.

People cooperate and make money together. As long as we keep the alkaline water and salt water in the formula secret, and we configure it every time and give as much as needed, then there will be no problem in terms of safety."

After hearing this, Wei and Li Jian looked at each other in confusion, as if they didn't know Li Hao. After the two looked at each other, Wei said: "How did you come up with these things? You should have never been exposed to such things as business."

It’s only right to pass.”

At this moment, Li Hao's heart skipped a beat, and he quickly said: "These principles are all in books. Tao Zhugong's Business Training and Guiguzi's Seven Strategies of Planning actually talked about these things. I just accidentally saw them and wrote them down."

After hearing this, Ms. Wei was confused, but she didn't say anything. She just asked Li Hao to calm down. She and Li Jian would do the next thing. She asked Li Hao to read the book carefully and ensure that there would be no problems in the exam seven days later.

, can enter school normally.

However, this also taught Li Hao a lesson. It is better to be cautious when doing things well. These are parents in this life, so it is not a big deal. For outsiders, it is better to have traces to follow.
