The school couldn't go, so Zhao Ping decided to simply set up a primary school in his study, and Zhao Ping studied by himself at home.

To the relief of the mother, Zhao Ping, who was accepted as a disciple by the gods, not only held the book himself, wrote while reading, and even learned to study with two Xiaolang and three little ladies when he had time, and he actually became their master.

While teaching them, Zhao Ping mixed in private goods from time to time, such as what to use pinyin to read without cutting sound, and what to use Arabic numerals instead of Chinese characters to capitalize numbers.

Zhao Ping found that in the study, Cuizhu came to learn after doing things most seriously, and was the most sensitive to arithmetic, and has learned to memorize the ninety-nine multiplication table is learning to add and subtract, Zhao Ping plans to let her learn multiplication and division after the one-dimensional quadratic equation.

And Lan'er may be too young, after being slapped by Zhao Ping, she can barely memorize numbers from one to one hundred with shallow eyes, but she likes poetry; The four Zhao siblings are somewhere in between.

At this time, Zhao Ping was writing carefully with Cuizhu and the two Xiaolang Books, and Lan'er jumped in. This girl ring is the most impatient, and she only has one pillar of incense time for each study, and she has to run out to play. She came in breathlessly and said, "Zhao Wengweng, they're back." ”

Before Zhao Ping arrived in the hall, the sound of Zhao Jie's laughter was already heard inside, as well as the crisp laughter of his three sons, the Hun family, and the Xi wife.

Seeing Zhao Ping coming in, Zhao Jie's loud voice was already echoing in the hall: "Mastermother, Xiao Langjun, the fairy soap in Zhaojiazhuang is so easy to sell, and all the two hundred yuan brought this time have been sold." Some people were disappointed when they saw that their own sales were finished, and asked when they would be able to supply them, and the old slave promised to deliver them tomorrow, and they were happy. ”

Speaking of this, he paused, and then said: "Now it is mainly the eldest mothers and sisters-in-law and the brothel women in the Qinglou, and a small number of merchants. Especially the women in the brothel of Qinglou especially like fairy soap, and their own families bought ten and got one free according to Lang Jun's instructions, and they bought thirty pieces of fairy soap at once. ”

Later, the sound of shoes hitting the ground came, and the voice of the mother also came: "It seems that fairy soap has gradually been accepted by the world." The reason why the brothel women in Qinglou are particularly fond of fairy soap may be related to their origins, and fairy soap may give them a fresh and pure feeling. ”

Zhao Ping stared at his mother, feeling how his mother, a young literary woman, had suddenly become a secular businessman.

Seeing everyone's puzzled eyes, especially Xizi's gaze, the mother smiled indifferently, glanced at everyone, and then said: "Ping'er, now my mother has finally put her mind at ease." I handed over twenty taels of silver to you for my mother, just with a kind of care, gambling to see if I could succeed, fortunately, the fairy soap succeeded. It seems that the immortal charcoal and immortal furnace should not be a big problem. ”

Zhao Ping's heart was very heavy, and under his own impulse, his mother was under heavy pressure in his heart, but fortunately, the fairy soap seemed to have seen the dawn.

Thinking of this, Zhao Ping nodded and said: "Immortal soap can now be assured of bold production, and strive to produce more than 1,000 pieces per day." ”

Zhao Jie was anxious, waved his hands straight, and said: "Lang Jun, the subordinates do their best, and the output is only about two hundred yuan a day at most, which is difficult to complete." ”

Zhao Ping thought for a while, then said: "For the sake of output, I have to hire personnel." ”

"No, resolutely not. This is the secret recipe of the immortal family, how can it be learned by outsiders. All the personnel, including the mother, spat at Zhao Ping together.

Zhao Ping walked back and forth in the room for a few steps, pondered for a while, and then said: "I naturally have a way to do this, which is to use the assembly line recipe to make it." ”

Seeing that everyone looked at him blankly, Zhao Ping had no choice but to explain: "The assembly line is to divide the production method into several steps, and each batch of people is only responsible for their own link, which not only speeds up the process, but also makes it more safe and confidential." ...... In this way, people are separated, the production process is completely separated, and the things are separated, they only know the process of their own link, and the other links do not know. Of course, the recipe and the time process are in their own hands. ”

Seeing everyone's thinking, Zhao Ping continued: "In order to further insure, you can turn the import of characters into twists and turns, so that they don't know where they have arrived at all. ”

Zhao Jie suddenly mentioned a question that everyone was thinking about in their hearts: "If they are connected together, sooner or later they will be able to figure out the production process, maybe the quality of their fairy soap is not as good as their own, but after all, they can also produce it." ”

Zhao Ping pondered for a while before saying: "This is indeed a problem, you might as well add some irrelevant links, or even the opposite link, such as adding a vinegar workshop next to it, so that your own people can not only produce vinegar, but also disturb their minds." By the way, they can even set up a soy sauce workshop at the same time. However, this increases the cost. Speaking of this, Zhao Ping looked back at his mother.

The mother pondered for a while, then gritted her teeth and said, "Since this is the case, then put all the copper coins and silver into it." By the way, you mentioned soy sauce, but is it the soy sauce that is only available in the legendary palace? ”

Zhao Ping nodded and said, "It's indeed soy sauce, not the sauce on the market." It has an incomparably delicious flavor and a moderately salty taste. ”

Zhao Jie took out a pen, ink, paper, and inkstone.

Zhao Ping said: "The soybeans are cooked, then fermented, dried and filtered, and the filtrate is soy sauce. Although the principle is simple, the process is not easy to master. The key control points are fermentation, yeast making, and drying of embryos. It takes only a long time to dry embryos, and it generally takes a year to be exposed to the open air, and the temperature is getting higher and higher, the better. Yeast is needed for fermentation, and this yeast is not easy to make. ”

Hearing this, everyone showed disappointed faces, and Zhao Di even rushed out: "Then what should I do?" Isn't it possible to keep the workshop going? After saying that, he regretted it and immediately covered his lips with it.

Zhao Ping took a sip of tea, and then continued: "Steamed bread fermentation is the use of yeast principle. Yeast is a tiny insect that is difficult to see with the naked eye. How do you make yeast? It is made from honey, flour, and urine. ”

When Zhao Ping said this, his mother frowned and stopped talking: "Ping'er, this is okay, the smell of urine is too strong, which is unacceptable." As she spoke, she fanned her tall nose with her hand, as if there was a smell of urine in front of her.

Zhao Ping glanced at everyone, saw that everyone had suspicious eyes, nodded, and said: "My mother's worry is quite reasonable, my recipe is for outsiders to see." Here's a way to get rid of the smell of urine. That is to mix the urine with charcoal powder, stir for half an hour, and then strain it with a white cloth. After two to three times of fine charcoal powder mixing, stirring and filtration, the smell of urine has been basically removed, and the substances in the urine are called urea. Even the faint smell of urine was swallowed up by the yeast worm. ”

The mother was puzzled and asked, "Yeast also eats urine?" ”
