    Chen Laoshi¡¯s work today is very different from the past. He has so much strength that he can do the work of three people by himself.  Mrs. Chen Wang was similar to him. While working, she opened her mouth and laughed, as if she had been hit by an ingot from the sky.

    The two couples struggled so hard that Chen Wanrong was so tired that hot sweat broke out on his head and he couldn't keep up with the rhythm of the two of them.

    Until it got dark, a simple cowshed was set up and Xiao Hei was driven into the cowshed. Chen Wanrong thought that the matter was finally over and breathed a sigh of relief.  However, Chen Wanrong's idea was wrong. The two couples were busy making a nest. After making the nest, they were busy getting fodder and feeding water, waiting on Xiao Hei as if they were taking care of guests.

    Such thoughtful and enthusiastic care was so meticulous that Chen Wanrong even felt a little jealous.

    After all the busy work, the two couples looked at Xiao Hei with great joy. They used words of praise that they knew little about to praise Xiao Hei for being different. They didn't even know he was hungry.  Chen Wanrong originally wanted to finish setting up the cowshed and prepare to make soap. Seeing that he was not cooking and no one was in the kitchen, he had to give up this plan and go to work in the kitchen alone.

    Chen Wanrong thought that he had a cow today, and Chen Laoshi would definitely have a few drinks, so he cooked a special portion of sweet and sour pork ribs. The color was bright and the aroma was overflowing. It was delicious. He was ready to celebrate.  When the food was brought to the table, Chen Wanrong realized that his prediction was wrong, how wrong it was.

    Chen Laoshi and his wife were really happy, a little too happy, and didn't even think about eating. As for whether the ribs cooked by Chen Wanrong were good or bad, they didn't care at all. They ate indiscriminately, lit a candle and went to see the cows again. Chen Wanrong  The scene that Rong imagined of Chen Laoshi being drunk did not appear at all.

    I woke up very early today, didn't have enough sleep, and worked hard for another day. I was almost exhausted. Chen Wanrong wished he could go to bed early, but he didn't finish his work and couldn't sleep even if he wanted to. He had to drag his tired body to boil water and prepare tanning agent.  .

    Chen Wanrong knew how to make full use of his time. He boiled water in a pot, put some well water in a bucket, crushed the lime, and put about ten kilograms in it.  Then pour more than ten kilograms of soda ash into the lime water and stir evenly with a stick.

    Chen Laoshi and his wife finally calmed down from the excitement of owning a cow and came over to help holding candles.  Tonight, Chen Wanrong was busy alone, but he was hanging around Xiao Hei. He felt very sorry. Chen Laoshi brought the firewood and volunteered, "Wanrong, make some caustic soda before going to bed."

    Chen Wanrong became sleepy and his mind was groggy. He couldn't react for a moment. He asked him a confused question and said curiously: "Dad, I don't do caustic soda."

    "Wanrong, if you don't make caustic soda, how can you make lime?" Chen Wang pointed at the steaming wooden barrel.

    Chen Wanrong finally understood and explained: "Father, mother, I am not making caustic soda, I am making soap. If I don't prepare now, it will be too late tomorrow."

    "Soap? What good thing is that?" Although Chen Laoshi didn't understand what soap was, he had great confidence in Chen Wanrong. As long as it was something Chen Wanrong wanted to make, it would definitely be a good thing.

    These words reached Chen Wang's heart, and he echoed: "Yes, Wanrong."

    Soap has a wide range of uses. It can be used for washing clothes, cleansing faces, and washing hands. If they are explained one by one, they may not be able to understand it immediately. Chen Wanrong chose to say: "Mom, don't wash the clothes you soaked.  Wait until I make soap for you to wash your clothes tomorrow. No matter how dirty the clothes are, they will be clean once they are washed."

    Chen Laoshi was not convinced yet, so he touched his forehead: "Wanrong, is it true? The clothes at home are washed with ash. They don't get dirty and need to be washed after being worn for a few days. Hey, my family is too poor and can't afford it.  Honey locust powder.¡±

    In ancient China, three main types of detergents were used to wash clothes. One is plant ash.  The main component of plant ash is potassium carbonate, which has similar chemical properties to soda ash. It is a commonly used detergent for ordinary people to wash clothes.  Of course, soda ash can also be used, but the dosage must be controlled, otherwise a piece of clothing will be ruined after just a few washes.

    The second type of detergent is honey locust powder, which was the main detergent used in ancient times.  As Chinese, we all know that the Yellow River is the mother river. The Chinese nation developed from the Yellow River Basin and gradually developed from north to south to the Yangtze River Basin.  The prosperous Jiangnan was a place where Dongyi people were entrenched during the Shang and Zhou Dynasties, and was regarded as a barbaric land. The first monarch to launch a large-scale conquest in Jiangnan was King Zhou, who has been infamous for thousands of years.

    When our ancestors lived in the Yellow River Basin, they used honey locust to wash their clothes.  Later, when we arrived in the Yangtze River Basin, there was no honey locust, and problems arose.  Life has to go on, clothes have to be washed, what should I do?  After much effort, our ancestors discovered that there was a tree in the Yangtze River basin. Its fruit was thicker and more plump than the honey locust. It could be used to wash clothes, and the effect was no worse than that of the honey locust.

     Our ancestors named it Soapzi, also called Soapberry.  Later, artificial detergents appeared and still used this name, which we still use today. This is the origin of the word "soap".

    The third type of detergent is trypticum. The emergence of trypticum is of great significance. Our ancestors have taken a big step towards artificial detergents.

    The most effective one is pancreatic juice. However, pancreatic rice is difficult to popularize because of its complicated production and high cost. It is a luxury product and only those princes, nobles, members of the royal family and dignitaries can afford it.

    The cheapest is plant ash, which costs nothing. Who doesn¡¯t have some ash at home?  This is the perfect way to wash clothes in a poor family like Chen Laoshi.

    The most common one is soap locust powder, which is made into powder and sold in the market.  The stain removal ability is much better than that of plant ash. It is the first choice for laundry in moderately wealthy households.

    Chen Laoshi has trouble eating. He has no money left to buy honey locust powder. This is a big worry for him. Whenever he mentions this matter, he can't help but sigh.

    Chen Wang said angrily: "Old man, Wanrong, can you still not believe it? Wanrong said it is easy to use, and it is easy to use. Don't think too much. Wanrong, what are you doing making soap? My mother always uses ash to wash clothes, how many times?  It's been ten years since I came here, so don't worry about it." She thought a little wrong, thinking that Chen Wanrong felt sorry for her and made soap to reduce her burden of washing clothes.  It was so joyful that Chen Wanrong had such filial piety, and he smiled like a pistachio.

    "Mom, if soap is made, it will definitely be very popular. It will be easier to sell than caustic soda. With it, we can live a good life." Chen Wanrong explained confidently: "Soap is very rare. It is used for  It is not cost-effective to wash ordinary clothes, but the effect of washing silk fabrics is particularly good. Mother, you think that there are not many other things in Datang, but silk fabrics, otherwise the Silk Road would not be so busy. "

    In modern society, soap is very common and can be bought for a small amount of three taels.  In ancient times, it was a luxury product, and only wealthy businessmen, royalty, and nobles could afford it. One of the important reasons was that alkali was used in the production of soap.  Soda ash was first used. Since soda ash at that time was naturally formed, its output was limited, which inevitably limited the popularity of soap.

    It was not until the advent of artificial soda that this problem was solved.  The advent of artificial soda was a landmark event in the history of chemistry. Chemical industry has since entered the stage of history as an independent industry.

    Later, the emergence of the chlor-alkali industry, which produced caustic soda through the electrolysis of salt water, made soap manufacturing more convenient, and soap entered the homes of ordinary people.

    In the Tang Dynasty, there was not enough alkali, so the output of soap was necessarily small. It would be too wasteful to use it to wash linen clothes with big holes like Chen Wanrong's body.  If it is used to wash silk fabrics, it will be used properly. If it is sold, it will be very popular. Therefore, it is not a problem to get rich. Who calls China the "country of silk"?

    This was said with confidence, and Chen Laoshi was greatly encouraged: "Wanrong, soap is so profitable, so don't make caustic soda, otherwise it will tire you out."

    "Dad, I can't make soap without caustic soda." Chen Wanrong yawned, extremely tired.

    ??Caustic soda is a very good chemical raw material with a wide range of uses, and of course it can be sold for a lot of money.  For Chen Wanrong, it is a very good raw material. With caustic soda, Chen Wanrong is like a roc flying in the sky. He can fly as far as he wants. He can make as many chemical products as he wants.  Indispensable.

    Mrs. Chen Wang looked at Chen Wanrong's tired face and felt distressed. She rolled her eyes at Chen Laoshi and stopped him from asking any more questions. She advised: "Wanrong, you are sleepy, you go to bed first."

    "Mom, I also need to prepare tanning agent." Chen Wanrong did not forget about business.

    Mrs. Chen Wang made a big deal: "Wanrong, mother will match you. Mother will remember that you have been matched with Zai Rong. Just leave it to mother."

    Chen Wanrong was exhausted and sleepy today. He might fall asleep if he held on any longer. He said, "Thank you, mother." He dragged his exhausted body, washed his face, washed his feet, and went to bed.  .

    Soap is my most promising product at the moment. To say it is a gold medal product is not an exaggeration. With the hope of making a fortune, I must have a good rest and work hard tomorrow.  (Remember the website address: www.hlnovel.com
