    "No need to try. The effect of soap is better than that of soap." Wu Jing took the shirt from Chen Wanrong, looked at it carefully for a while, and concluded with certainty: "The effect of soap is much better than that of soap."  , this is the best washing product I have ever seen.¡±

    "I've seen it, I've seen it!" Huang Boming cupped his fists and apologized to Chen Wanrong, saying: "Brother Wanrong has this miraculous trick. Bo Ming's knowledge is shallow, his words are incomprehensible, and there are many offenses. Brother Wanrong, please  Forgive me."

    It is not easy to admit a mistake in person. Chen Wanrong had to admire the simplicity of the ancient style from the bottom of his heart and said with a smile: "Mr. Huang's words are serious, so why bother about trivial matters."

    Wu Jing clasped his fists and admitted his mistake and said, "Brother Wanrong, please forgive me." He took out a delicate sandalwood box from his arms and said, "Brother Wanrong, please look at this, this is the pancreatic juice." He opened the lid and a stream of water came out.  The fragrant scent of roses immediately filled the room.

    ¡°It smells so good, it smells so good!¡± Chen Laoshi touched his nose and praised.

    Chen Wanrong took a closer look and saw that the box contained a round pink solid. This was the crystallization of the wisdom of our ancestors. Chen Wanrong couldn't help but feel excited and said: "Mr. Wu, can you show it to me?"  "

    Now Wu Jing admires Chen Wanrong very much, and there is nothing he can't agree with. He smiled and said: "Brother Wanrong, please take a look." He handed the box to Chen Wanrong's hand.

    Chen Wanrong took it and put it to his nose to smell the fragrant rose scent, as if he was holding a bouquet of roses instead of soap.  The index finger of his right hand gently caressed the pancreas, and a smooth feeling similar to soap came from the fingertips, which made him feel refreshed.

    Chen Wanrong's technical attainments are extraordinary. Just by the smoothness, he knew that this product must be extraordinary. He praised: "Good stuff! May I ask Mr. Wu how to make this soap?"

    When Li Qingquan first mentioned pancake, Chen Wanrong wanted to know how to make it, but Li Qingquan didn't know it either, so he had to give up.  Chen Wanrong has a special hobby for technology, not to mention the value of this kind of thing. Chen Wanrong knows better than anyone else. He has been thinking about it, but he has no clue at all. When he meets a university scholar like Wu Jing, he doesn't ask.  I understand, wouldn¡¯t it be a pity?

    "Brother Wanrong inquired about it, and Wu Jing didn't dare to tell you the truth." Wu Jing said happily: "This pancake has two names, one is called bath bean and the other is called pancake. The reason why it is called bath bean is because it was originally called bath bean.  Soybean powder was used in the production. This thing appeared in the Northern and Southern Dynasties. Wash the blood from the pig pancreas, remove the oil layer, grind it into a paste, add soybean powder and spices, mix evenly, and dry it to get bath beans.  ¡±

    As soon as he finished speaking, Huang Boming tapped his hands lightly, making a crisp popping sound, and was full of admiration: "Wonderful ideas, wonderful ideas, wonderful craftsmanship! Who could have imagined that such an ordinary thing as pig pancreas could have such quality?"  What's the magical effect? ??I heard Brother Wu talk about this before, and now I have a different feeling when I hear it again. The person who invented it must be a very smart person!"

    Wu Jing nodded in agreement and said with regret: "It's a pity that the name of this ancestor can no longer be recorded! Such a wonderful thing should leave a mark in the history books, but there is no way to check it. Although I am ordered to write history, I cannot leave a mark for him.  Famous!"

    Even a leading historian like Wu Jing can¡¯t verify it, so who else can do anything?  Chen Wanrong smiled and said: "We can call this ancestor Wuming Doe, a very smart and anonymous Wuming Doe!"

    "Anonymous? Wonderful!" Wu Jing applauded.

    After hearing Wu Jing¡¯s explanation, Chen Wanrong was shocked. Of course, Chen Wanrong was not as shocked as Huang Boming by the whimsical ideas of his ancestors, but by the technical content.

    After this treatment, pig pancreas has a strong decontamination ability and can be used to cleanse the body, face and hands, or even wash fabrics. This is very scientific.  Pig pancreas is rich in enzymes, and grinding it facilitates the secretion of enzymes. This is a very good method.

    As for soybean flour, let alone it, it is rich in saponins and lecithin, and lecithin not only has a foaming effect, but also has an emulsifying effect.  Adding soybean powder not only strengthens the washing ability, but also moisturizes the skin, making it very suitable for cleansing the body, face and hands.

    As early as the Northern and Southern Dynasties, our ancestors had this understanding. Could Chen Wanrong not be shocked?

    After being shocked, Chen Wanrong quickly thought about it. Additives are added to the soap used in modern society to enhance its effect.  There were no such additives available in the Tang Dynasty. Soy flour, a convenient and easily available raw material, could be added to enhance the decontamination ability and maintain skin.

    Anyone who has taken a bath with soap knows that it will dry out the skin in a short period of time and even cause allergies. This is because an acid-base neutralization reaction occurs on the skin surface.  The skin is slightly acidic, with a pH value of about 6.5, while soap is about 10. After taking a bath, the pH value will rise and the skin will become dry.  About half an hour later, the pH of the skin will return to normal.

    It is impossible to avoid the acid-base neutralization reaction by adding soy flour, but it can reduce the harmfulness and facilitate skin care.  In this way, the performance of the soap is greatly improved, and the cost of the soap is slightly increased. It doesn't matter if the soap is not popular.  Chen Wanrong secretly made up his mind that this matter must be done quickly.

    Just when Chen Wanrong changed his mind, Wu Jing went on to explain: "Later, adding sugar when grinding pig pancreas had a better effect. Now, the craftsmen have found that adding soda ash is more effective than using soy flour.  Okay, that's why we have this pancake." He took the pancake from Chen Wanrong's hand and shook it lightly in his hand to attract attention: "Because it uses pig pancreas, it is also called pancake."

    (Note: As a side note, some friends are wondering whether soda ash existed in the Tang Dynasty. In fact, soda ash was used for a long time, even before the Tang Dynasty. This is a living example, and friends do not need to doubt it.  .)

    Huang Boming said with great regret: "Although this method is good, it is difficult to popularize. There are too few pig pancreas, and only a few people can afford it. Brother Wu is successful in making history, so the emperor will reward you with a box. Otherwise, you will be like me.  I can¡¯t even look at it.¡±

    ??Yezi was the highest-grade cleaning product in the Tang Dynasty. It was very precious and had been reserved exclusively for the imperial palace. It could not be seen by ordinary people. Even the ministers would not use it unless they were rewarded by the emperor.

    Wu Jing agreed with this from the bottom of his heart and said: "Yes, there are too few pig pancreas, and there is simply not enough. The emperor gave me this box, but I couldn't bear to use it, otherwise it would have been used up long ago. Now it's better, there is  After understanding Brother Wanrong's wonderful method, and lard is much more abundant than pancreas, soap will be popularized in the world."

    Whether soap can be popularized in the world does not depend on whether there is enough lard. Even if lard is not enough, vegetable oil can be used instead. Oil is not a problem. The problem is that insufficient alkali production will limit the popularity of soap.

    Chen Wanrong was about to change the topic when he heard Wu Jing continue, saying: "Brother Wanrong, this method is wonderful. If you sell the soap on the market, it will definitely be very popular and sell at a good price.  "

    This is the inevitable result. Chen Laoshi, his wife, and Chen Zairong can¡¯t help but be happy.

    Chen Wanrong heard what he said, and it seemed that he had something to say. Sure enough, Wu Jing changed the subject and said, "However, if Brother Wanrong can make slight improvements in a few aspects, he will be more popular."

    He clearly had an opinion but he expressed it in such a tactful way. He was indeed a very knowledgeable person. Chen Wanrong smiled and said, "If you have any shortcomings, please ask Mr. Wu for advice."

    ¡°I don¡¯t take advice seriously, I just have some opinions. If Brother Wanrong doesn¡¯t mind, I will speak out.¡± Wu Jing still said it tactfully.

    His tone was solemn, and it seemed that the problem was not small. Chen Wanrong couldn't help but feel a chill in his heart, and hurriedly said: "Mr. Wu, what's the problem?" (Remember the website address: www.hlnovel.com
