At this moment, the body of the bandit and the body of the guards of the Drunken Immortal Building were all sent over by Bu Zhengqing and reported to the official, and then Yang Gong went over to deal with it. Although Cao Yi has made it clear to him in private, there is still a general judgment to supervise outside the prefect, so the process that should be done is still indispensable.

Cao Yi is neither a reporter nor a public official, so he cannot be a bystander. At this time, he said goodbye to Yang, and then took Red Sleeves to the Zuixian Building to have a look, as the actual controller of the Zuixian Building, except for the time when it was not open at the beginning, it took a lot of time and energy to prepare, but since the opening, Cao Yi rarely cared about the affairs of the Zuixian Building, even if the Zuixian Building in Yangzhou has begun to choose a good site and is under construction, Cao Yi also completely delegated power to Wang Zhiyuan and Red Sleeves, so that the two of them are fully responsible.

When I arrived at the Drunken Immortal Building, it was lunch time, and there were quite a few people dining in the restaurant. There was nothing to do, Cao Yi took a look at it casually, ate some melon and fruit cakes in the restaurant, and then went to the market with his red sleeves, he decided to make something good that was convenient for his life and sold by the Taibai Chamber of Commerce.

After arriving at the bazaar, Cao Yi bought all the lard in the bazaar, and this sudden operation made Red Sleeves stunned for a while, and he had the courage to sneak forward and wipe his son's forehead, and determined one thing, that is, there was no fever. Under Cao Yi's gaze, he smiled and slowly retreated. However, because they bought too much, one car would definitely not fit, and in the end, there was no way, so the two had to go home first, and then send their servants to the bazaar and all of them moved back to the Qingyun Pavilion of Caofu.

"Red Sleeves, you can wait and ask someone to go to the market and buy some cheese, honey and flower petals, a small jar of cheese and honey will do, buy more flower petals, buy a basin-sized one." At the same time, I instructed the house to collect all the ashes of the plants and trees and move them to the Qingyun Pavilion, and I have other uses. ”

The red sleeves flashed with good-looking eyes, and the bright eyes looked at Cao Yi, because he didn't know much about what the son was going to do, so his expression was a little coquettish at this time, but he still nodded and agreed.

After arriving at Qingyun Pavilion, Red Sleeves instructed different small servants according to the arrangement Cao Yi said, and let them act separately, after two sticks of incense, Red Sleeves came to Cao Yi, who was writing and painting in the Cultivating Heart Hall: "Childe, everything you said has been prepared in the courtyard outside." ”

"Okay, I'll go over right away, you let the two little guys stay in the yard and give me a hand." Cao Yi said without raising his head, still drawing on the drawings, when the red sleeves left, he glanced at the drawings a little, wanting to see what Gongzi was busy with, but found that there seemed to be a lot of Persian and Hu Wen written on it, staring at it for a while, I found that I couldn't understand it, and there were some lines and prismatic patterns, which looked a bit like Gewu, but according to Gongzi's painting skills, she couldn't understand it, so it should be normal. Thinking so, Red Sleeves left the Cultivating Heart Hall first.

Cao Yi finished writing, looked at the drawings, checked it, and it seemed that the steps were correct, so he went out after looking at it.

"You two pour the ashes into the bucket, and then add more than double the weight of the ashes, almost just a little more than the ashes, yes, that's it, and keep stirring." Cao Yi commanded the little guy to work on the side.

"Childe, what are you doing here?" Redsleeves asked in a whisper next to him.

"Make something for bathing and washing your hair," Cao Yi said with a smile.

“…… After making it...... Will be better than ...... Are soaphorn and bath beans still useful? Redsleeves asked suspiciously.

"Of course, otherwise why would I do this, the newly made one is called soap, and the cleaning effect will be much better than that of bath beans, not to mention soap horns." Cao Yi said with a sigh.

Red Sleeves stood beside Cao Yi, looking at Cao Yi sideways, the winter sun shone on Cao Yi in the afternoon, which seemed to make Cao Yi's image more brilliant, and Red Sleeves looked a little dazzling for a while.

"Red Sleeves...... Tea! Cao Yi screamed that Red Sleeves didn't respond and then screamed again, only to wake up Red Sleeves from his fascination.

"Ahh Childe, you say. Redsleeves blushed and said a little embarrassed.

"Oh, I'm asking you to pay attention to the production process, and you're responsible for making this project bigger." Cao Yi turned his head again and said to Red Sleeves.

Red Sleeves gathered his mind, nodded, and began to carefully observe how Cao Yi commanded the whole process, what steps were in between, and how the two little guys worked.

After the plant ash was mixed with water, Cao Yi asked one of the servants to take out a piece of cloth and cover it on an empty bucket, then fix it, and then pour the previously stirred plant ash mixture liquid into it, and filter it through the cloth to remove the impurities and gray matter in the mixture.

The filtered plant ash mixture is then heated. "This plant ash mixture is also called lye, and now I'm heating it to remove water and increase the concentration of alkali." Cao Yi said.

"To judge whether its concentration is enough, you put an egg in it, and if the egg floats, it means that the concentration of the lye has been improved." Cao Yi looked at the red sleeves and said carefully.

"At the same time, when we increase the concentration of the lye, we can also heat the grease of the lard, and then pour all the flower petals into the grease and keep it on medium heat, and keep the temperature up, not too high, not too low. The purpose is to burn out the aromatic essence of these petals, which are then slowly absorbed and fused by the oil. Then what we have to do is wait for the oil to cool down and then extract it by filtration. Cao Yi said to Red Sleeves while directing the little guy to work.

"When adding floral essence, you can also add a little cheese and honey at the same time, so that after the soap is made in the later stage, in addition to the floral fragrance, there is also a little honey and milk flavor." As Cao Yi spoke, he poured a piece of medium-sized cheese and a small jar of honey into it.

After the grease is saturated, let the small guy stop heating, and after a stick of incense time, after the grease has warmed up slightly, it is still the same as the previous plant ash mixture, filter with a cloth, remove the petals and other debris, and only retain the oil with the essence of the flowers.

"Oh yes, Red Sleeves, the lye water I said before, don't store it in iron containers, you must use porcelain to store it, remember!" Cao Yi suddenly turned his head and instructed Red Sleeves, with a serious face, and Red nodded heavily. "Knowing Childe, I will always remember it."

"Well, then add the oil infused with floral essence, cheese and honey to the concentrated alkaline water, and pour a little green lotus wine, a small bottle is enough, and then stir while heating, stirring all the time, until it is very thick and thick." Cao Yi continued to instruct the red sleeves.

"After it is very thick, we will stop heating, and then pour the soap liquid inside into the mold, because now the time is too rushed, so we also do not make a good mold, only round and square two, and so on time, you can arrange craftsmen to design a few good-looking molds, when the soap liquid is poured in, it is to form a variety of beautiful shapes, and then make it more delicate and you can also carve patterns or beautiful poems on it." Cao Yi instructed the little guy to pour it into the few round and square molds, and as for the remaining soap, it could only be poured into a large wooden barrel, and when the time came, it would be taken out and cut into pieces with a knife after it had completely cooled.

Cao Yi looked at the soap liquid poured into the mold and the big wooden barrel, with a happy smile on his face, clapped his hands and asked, "Red sleeves, are you familiar with the intermediate process steps and points to pay attention to?" ”

Red Sleeves nodded ignorantly, and said softly: "Childe, in the process of fusing floral essence, cheese and honey with oil in the middle, can you use other things instead, such as fragrant fruits, other flowers, or sandalwood, musk and the like?" ”

Cao Yi laughed heartily, "Of course you can, it's all called soap, it can be flower soap, grape soap, watermelon soap, sandalwood soap, musk soap, or milk soap with a single milk flavor, honey soap with a sweet taste, you can do it." In fact, it is the same as osmanthus wine, wine, and medicinal wine, and when you put different materials, you will have different aromas. ”

Red Sleeves nodded thoughtfully, and then asked, "Then Childe, how long will this last?" ”

"Well, it's so cold outside now, it is estimated that it will be fine in the mold in a while, and in the big barrel, it will at least wait for tomorrow, right?"

Red Sleeves approached the soap liquid in the mold, lowered his head and sniffed with his nose, a floral fragrance mixed with the milky aroma of cheese came to his nose, raised his head happily, and asked: "Childe, it's amazing that this can still have this kind of fragrance when so much lard and plant ash is put in, uh......" Red Sleeves couldn't help but shudder after saying that, mainly thinking that a person first poured ashes all over his body, and then was drenched in lard, thinking that he was a little afraid to think about it anymore.

Then he asked timidly, "Childe, can this really be used to wash your body and clean your hair?" ”

"Haha, of course, the wash can be clean, and there will be a very fragrant fragrance left on the body, and it is guaranteed that the white face will be like snow after ten days, and the skin will be like clotted fat after twenty days." Cao Yi laughed, of course, the last sentence was just his temporary nonsense advertising slogan.
