He Qiaowei watched the two of them play dumb riddles, believing in a book for a while, making himself dizzy, watching them interact, his heart ached.

Star fruit handed over the formula to He Qiaowei and asked him to go back to find someone to experiment slowly.

In fact, the formula she gave only used quicklime, although the process was complicated, but in order not to disappoint him, she felt that the raw materials she found could be used, so she used the soil method to make it.

First find a wooden barrel, fill it with water, throw a certain dose of quicklime into the water, only to hear a swish, and then tumble and become piping hot.

This is the reaction of quicklime and water to produce a calcium hydroxide solution, also known as hydrated lime.

Then in this bucket of hydrated lime, pour soda ash, the bucket of water boiled in an instant, and a large amount of water vapor came out, which would immediately evaporate one-third of the bucket of water, and at this time the bucket was already turbid, and the bottom of the bucket could not be seen clearly.

This is the reaction of hydrated lime, calcium hydroxide and soda ash sodium carbonate to produce calcium carbonate and sodium hydroxide. Calcium carbonate deposits clouded the bucket, and the large amount of heat released by the reaction dried up the water.

After letting the barrel sit for a while, the calcium carbonate will sink to the bottom of the barrel, and the transparent sodium hydroxide solution, that is, caustic soda, will float on top of the calcium carbonate.

The sodium hydroxide solution was spooned into another barrel with a spoon little by little, and then filtered with gauze again, so that the calcium carbonate was removed, and the useful one was the caustic soda.

Put the iron pot on the stove, heat the caustic soda solution, and at the same time pour the soybean oil into the pot little by little, after the soybean oil is poured in, and then stir continuously with a stick, the alkali and the oil undergo saponification reaction at high temperature, the oil gradually disappears, and a layer of viscous liquid grows on the top of the iron pot, which is the soapy liquid that star fruit wants.

However, at this time, the temperature of the soap is relatively high, or a semi-solidified state, at this time, this layer of soap can be fished out with a spatula, put it in a wooden box and squeeze it into a square, and then pour it out and put it on the ground to dry.

After an hour, when the liquid solidifies and dries, it will take on a dull yellow color, which is the soap after it has been formed. (Du Niang consulted, to be examined)

He Qiaowei got the formula, he was in a good mood, he forgot his worries when he came, as long as he could work with her and see her often, why not be by her side like this.

After sending He Qiaowei away, Lu Qiyu couldn't leave for a long time because he had to sit in the Rejuvenation Hall, so he was reluctant to go back.

Star fruit got the right to use the barren mountain, and began to recruit people to dig tree pits, Liu Yancheng to transport the peach trees are already on the way, although it has now entered May, the best time to plant should be in the beginning of spring, but this is the north, ten days and a half at night It doesn't matter much, but she wants to dig the tree pit before Liu Yancheng transports the saplings.

The people who work say that the peaches are rich, and they are tossing and turning, and the fruit trees planted in this barren mountain are all blind to the silver, and there is no water on the mountain, and they are dead when they are planted.

This reminds the star fruit that the lack of water in the fruit trees is a big deal, and now there is no time to think about it, the boat will naturally go straight to the bridge, and there will always be a way.

Within a few days, Liu Yancheng's convoy was really fast, it turned out that he had saved a lot of time to arrive, and it was already planting late, and he was afraid of delaying her time.

After two days of busy work, it took money to hire short-term workers to plant all the peach trees, and the star fruit was relieved and completed a major project.

Liu Yancheng specially congratulated her and Lu Qiyu on their marriage, and star fruit was a little embarrassed, after all, his sister wanted to marry Lu Qiyu alive or dead.

Liu Yancheng asked tentatively: "If Qiyu accepts another concubine, do you agree?" ”

Carambola listened, thinking that he was begging for his sister, she replied domineeringly: "Brother Liu, the person who made the idea of this matter is not me, if you ask my opinion, I will not stop it, but my life with him has come to an end, I am a person, there is a kind of temper, it is my man I will not share with others, if he has the heart to accept a concubine, it means that the heart is no longer in me alone, then I will make room for him, I don't care who he likes to go, and he doesn't want to appear in front of me." ”

Liu Yancheng listened, smiled slightly, and said, "Do you know how he drove my sister back to the capital?" ”

Carambola listened to it, a little curious, since he took over Piaoxiang Building, she hadn't asked what was going on.

"He said that he likes it in his life, and only loves Peaches, even if she is working hard, fighting, in the end it is in vain, he spent money to buy my sister's restaurant, and used his own power to make her have no place in the town, so I brought her back to the capital."

"He's so ruthless, but he's very handsome, I just like his cunning appearance, and his serious appearance, he deserves to be the man I like."

"Eh, it's okay to be a little sympathetic, my sister even knelt down and begged him, he didn't allow him not to be a concubine, he said that his woman didn't allow him to have other women around him."

"I asked today and believed it, he didn't lie, if you were really domineering, you won his heart and made him die for you."

"Are you complimenting me? Having said that, Brother Liu, why don't you marry a wife, you are about the same age as Brother Lu, why don't you see you tempted by girls. ”

When Liu Yancheng heard this, he suddenly felt a little emotionally lost, and said: "It's hard to say, there is a corner of my heart that has always been inhabited, and when she will automatically quit, I think it will be that time." ”

Star fruit thinks about everyone's sad past, and it is estimated that he also lives in his heart a princess who does not allow other girls to approach.

After sending Liu Yancheng away, star fruit could finally take a breath, which made her suddenly remember that she still had to develop soap.

In fact, when he gave He Qiaowei the formula, he already had the prototype of configuring soap.

First of all, find caustic soda and soybean oil, or refined lard, with these two things, the rest is easy to do.

Basically, it is the result of the saponification reaction of oil and lye, and after the curing and maturation process, a certain amount of spice is added, and then the soap that the peach wants is made.

It is said that it is simple, and the peaches have also been compared and blended countless times, cooled and hardened for a certain period of time, and then taken out of the mold, and finally made into a fragrant and foamy soap.

From the grease formula to a piece of soap in the hand to rub out a soft foam, the ecstatic sense of accomplishment is not experienced by people who have never made handmade soap, star fruit made a free soap, I really want to tell Lu Qiyu as soon as possible, but the ancient communication is backward, I really miss the modern telephone, and immediately tell him the good news.

At the same time, there was also good news from He Qiaowei's side, saying that he had made soap that could be disinfected and sterilized, and when he brought the sample to star fruit, the two were overjoyed.

He Qiaowei also discussed the specific details of the cooperation with Peach, because he was happy to have a few more drinks with Uncle Yang, but it caused a big disaster.
