Chapter 705: 706

"Tread..."

A few minutes later……

Catherine came back with things in her arms, handed them to Liu Feng and said, "Are these things enough?"

"Enough." After Liu Feng took the hand, he started to carve patterns with a carving knife.

"Liu Feng, what are you going to do?" Lucy asked curiously.

"Make a mold for soap." Liu Feng responded without moving slowly, "You can also make a mold that you like, and you can use it when you make soap."

"Huh? You can have this." Lucy and Catherine's eyes lit up, and they immediately started to make it.

"Crack, click..."

half an hour later.

"Mina, don't stir it anymore, let him settle down." Liu Feng said to Mina.

"Okay." Mina breathed a sigh of relief and shook her sore arm.

"Crack, click..."

Another half an hour passed, Liu Feng put down the mold in his hand, turned his head and looked at the girls who were seriously carving with their heads down, and couldn't help grinning.

"It should have settled." Liu Feng turned his head and looked at the ceramic pot containing the plant ash water. He could clearly see two layers of plant ash water. The upper layer contained clean plant ash water, and the lower layer contained settled plant ash.

"Master, do you still want to stir?" Tess asked curiously, her purple eyes were eager to do something.

"I'll let you do it later." Liu Feng shook his head lightly, and used another ceramic pot to get out the relatively clean plant ash.

"Oh." Di Si's mold is a circular groove, and any pattern is useless, so she has time to stare at Liu Feng.

"Now we need to use the soil method to test the alkali content." Liu Feng took an egg and gently put it into the jar of plant ash water.

Finally, it was found that the eggs sank and floated in the water, but neither sank to the bottom nor floated on the top, which means that the alkali content in the plant ash water is still acceptable.

"Huh? This is so amazing." Tess was surprised.

"This is the charm of chemistry." Liu Feng responded casually, and then poured the clean lard into the ash water.

In the hot weather of summer, lard does not solidify at all. If it is winter, lard has to be heated and melted.

"Chemistry?" Tess was a little confused, what is this?

"Come on, stir at high speed." Liu Feng handed the ceramic jar to Niujiao.

"Okay." Tess took over the hand and started stirring immediately.

"Add some fragrant pollen." Liu Feng poured the freshly crushed petal powder into a ceramic jar.

"It's... a bit sticky..." Mina leaned her head over and shouted.

Ten minutes later.

"Okay, Tees, stop it." Liu Feng estimated that the materials could be fully fused.

"Huh..." Tess heaved a sigh of relief, her breathing was a little short.

"Here, bring all the molds here." Liu Feng took the ceramic jar, picked up the spoon on the side, scooped out the viscous liquid from the ceramic jar, and poured it into the prepared molds on the side.

"¨. Good." The women immediately pushed the strange-shaped mold over.

This jar of semi-finished soap was just enough to fill everyone's molds.

"Okay, it can be used after it solidifies." Liu Feng put down the spoon in his hand and smiled lightly.

"Master, is this all right?" An Li's brown eyes filled with astonishment. The making of this soap is much easier than I imagined.

But the materials used to make soap are beyond my imagination. They are lard, plant ash, water, and pollen.

"This..." Lucy was stunned.

It was only now that everyone realized that this soap would do just that.

"It's not that mysterious..." Catherine complained, thinking that such a high-end soap should be made of precious materials.

But...it's all simple things.

Nicole carefully picked up a mold, put it in front of her nose and smelled it, and suddenly there was a faint floral fragrance, which did not have the unique smell of wild boar oil at all, but it smelled very good.

"It turns out that soap is made like this, it's amazing." Mina marveled, and there was a look of surprise in her blue eyes (Qian Zhao).

"Master, what is the principle of this? Is it magic?" An Li was a little confused. How could this lard and plant ash be turned into soap?

"Soap, the main ingredients are alkali and oil, plant ash..." Liu Feng briefly talked about the ingredients and principle of soap. Just seeing the dazed and dazed expressions on everyone's faces after listening to it, I knew that I was talking for nothing.

Of course, most of the raw materials of soaps used on the earth are replaced by chemical substances.

"In a few hours, let's see if the soap can be successful. If possible, you can follow this method in the future." Liu Feng said softly.

He was thinking, if there is a lot of oil, he can open a soap shop, mainly because the raw materials are limited, especially alkali.

The alkali content obtained by the local method is still a bit low, and the cleaning effect is definitely worse than the soap on the other side of the earth.

"One update, (￣▽￣). It took a lot of time to check the information, please support."

After Liu Feng finished making the soap, he went back to the study, and the cat-eared lady followed behind, holding a mold that she had carved herself. Looking at the shape, it looked a bit like a kitten with crooked growth.

Wei Ya put away her soap mold and left. She has to go back to class, and the reading competition will start tomorrow, so she has to go back and make some preparations.

Now the stage is set up in the school's playground, and the poems and words to be recited are all prepared by the students themselves. Wei Ya just teaches them how to recite, what adjectives should be used and what intonation, and let the students practice in the past few days.

Tess also left, she came back just to grab a meal, and now she should go back and continue her inspections when she is full.

Nicole took a notebook and carefully wrote down the soap making process, planning to make some different soaps by herself if the soap was formed tomorrow.

"By the way, you can add a little pearl powder to it, which can maintain the skin, but the cost has increased, and it can be supplied to those nobles and businessmen..." Nicole said to herself, thinking about Liu After Feng's operation just now, he continued to write.

Princess Lucy went back to her room. She had a sudden inspiration just now and was about to start writing the second book of the "City of Miracles" series. She decided to write soap in it. Of course, the production process will not be described.

As for Frey, she still went back to practice at the air force base, and waited for her elder sister by the way. Although she knew that at the speed of Leya and others, she hadn't reached the valley yet, but even so, she still had to wait. .

This time Leya was going to kill the dragon, even with the military crossbow and anesthetic given by Liu Feng, she still felt worried to some extent.
