In the blink of an eye, it was late February, and all the production activities in the valley were starting to operate.

As the temperature rises, the grassland begins to turn green, and all kinds of cattle, sheep and red deer are also scattered into the wild; After a winter of enclosure, the cattle began to rejoice all over the field.

Farmland has also begun to loosen the soil and fertilize, and a wheat field has been set aside to experiment with the effect of nitrogen fertilizer on increasing yields.

What made Abu happiest was that Liu Yuanlu made soap independently, except for the beginning when Abu explained the general process to him and successfully fooled him, he basically didn't ask Abu for advice after that.

When he came to Abu that day, he took out two objects very casually, put them in front of Abu's eyes, and said, "Let's see if this is the soap you said, I have already made it myself, and there is no difficulty." ”

When Abu looked closely, he found that there were indeed two bars of soap in front of him, one of which was yellow and white, and the other was a faint and transparent light yellow.

Looking at Liu Yuanlu again, although the expression on his face was light and light, his slightly upturned beard moved, as if to say, "I'm amazing, come and praise me, come and praise me." ”

Abu was indeed a little surprised, he just briefly described the process to Liu Yuanlu at that time, and the specific links in the middle had to be designed and tried little by little, but he didn't expect him to really complete it independently.

Then he washed his hands to test, and the decontamination effect was indeed not said, and the materials used were carefully selected, which was better than the soap of later generations.

Of course, Abu did not hesitate to praise, saying that the alchemy family is an alchemy family, the second brother's talent is superior, it is indeed unmatched, the younger brother is ashamed of himself, Liu Yuanlu's mustache has been proudly cocked, obviously enjoying Abu's slightly exaggerated flattery.

When Liu Yuanlu and Abu experimentally threw soap to the people in the valley to test, everyone had a very good impression of this unsightly gadget, whether it was bathing or washing clothes.

The delicate and smooth skin and slightly scented clothes made people irrepressibly flock to Liu Yuanlu's studio.

Everyone took out the beef and mutton fat that they were usually reluctant to use, and asked him to help make more soap.

In the end, Liu Yuanlu was annoyed and had no choice but to expand the venue, start from scratch, and teach everyone how to make soap hand in hand, after all, the process is less dangerous.

After successfully refining soap alone, everyone has a deeper understanding of the power of science and technology, and is more attentive to the learning of knowledge, after all, it has really changed everyone's life.

At the same time, Abu carried out philosophical education and popularization in a timely manner, so that the people in the valley gradually formed in their minds the concepts of seeking truth from facts in doing things and practice as the only criterion for testing the truth, and roughly established the simple materialist dialectical thinking.

In the process of making life, people are also consciously digesting and applying these ideas.

The most obvious phenomenon is that in the production process of soda ash, lime and other products in the past, everyone just mechanically followed Abu's guidance and implemented it at a glance, but now they often ask all kinds of whys, and sometimes it is difficult for Abu, who claims to be a top student, to answer.

Once, Li Zhengqi asked Abu why quartz sand turns into transparent glass when it melts.

Abu could only vaguely answer that after the light hits the glass, it will be refracted but it will become transparent because the refraction time is relatively short.

As for what happened and how it happened, he couldn't answer, after all, he was not an all-powerful being.

Li Zhengqi finally said to Abu, saying that Mr. does not have to blame himself, no one is perfect, and no one can do fault.

Although it sounds like a comforting word, it sounds awkward, and it seems that ignorance is a sin.

In terms of product manufacturing, the biggest consumption is table salt, and other raw materials are basically ready-made.

In addition to the reserves of salt, which is necessary for life, the remaining salt is invested in industrial production, which is then converted into soda ash, glass, paper and soap.

Children and young people are involved in all kinds of farm work and product manufacturing processes in their spare time, and there is no such thing as child labor. Being able to participate earlier, combined with the knowledge learned in the classroom, can be transformed into their own abilities earlier and faster.

After everyone was able to make soap, Liu Yuanlu took a step out of it and worked hard to build his working laboratory.

The renovated workshop is four or five times larger than before, and the various configurations inside are also at the forefront of the current state-of-the-art.

He has here all kinds of glass instruments with capacity scales that Li Baotian has carefully built for him, there are flameless alcohol lamps that specialize in burning alcohol, there are thermometers that accurately measure temperatures, high-quality white paper that records various data is used casually, and the corners of the room are filled with fine sand used to prevent fires.

Even according to strict standards, it can be regarded as a qualified chemical laboratory even in later generations.

Abu gave him the task of extracting as many individual elements as possible according to the periodic table, as well as collecting and sorting out the various methods of preparation.

According to the standards of later generations, Liu Yuanlu has thoroughly mastered the knowledge of chemistry at the junior and senior high school levels, and is exploring to a higher field.

Some displacement reactions and acid-base reactions have been played, and the work he has to do is to use various actual raw materials to purify and restore the essential elements of the world.

On the day the laboratory was built, this fanatical alchemist was so excited that he burst into tears, and sighed vigorously that he was really right to follow Abu here, this was the paradise he dreamed of.

One day Abu went to Liu Yuanlu's place to do a small experiment, Liu Yuanlu asked him what he wanted to do, Abu smiled and said: "Yunniang's birthday is about to be, I am going to make her a birthday gift." ”

Liu Yuanlu didn't say much, and watched Abu fiddling with interest, only to see Abu put a round flat glass in his hand on the table.

He first took some quicklime from the side, put it into the crucible, added water, and put some soda ash at the same time, and after standing for a while, poured the clear solution in the crucible into a test tube. While operating, he said: "Quicklime reacts with water to form calcium hydroxide, and then soda ash is added to produce a chemical reaction to obtain sodium hydroxide." ”

Abu turned his head and asked Liu Yuanlu: "Second brother, where is the nitric acid?" I can use a little. ”

Liu Yuanlu took half a tube of nitric acid from the back room and walked out, saying, "Be careful, this concentration is a bit high." ”

Abu responded, took it, and took out some loose silver from his pocket, added it to the test tube, slowly dissolved it under the stirring of the glass rod, and continued to explain: "Dissolve the silver into concentrated nitric acid, I guess you are more familiar with this chemical reaction process than me, haha." ”

Liu Yuanlu also laughed, remembering the scene when the two of them met, although it didn't take long, it was like a world away.

Then Abu took a handful of raisins out of his pocket, put them in a beaker, added a little water, and began to heat them.

Liu Yuanlu could understand when he watched Abu dissolve the silver with nitric acid, but why did he even use grapes at this time, and couldn't help asking: "Third brother, what are you doing, why do you still use grapes?" ”

"Haha, second brother take a closer look, I'll explain it to you later, but the general principle is to use the reducing ability of glucose solution to replace the silver."

After the raisins and water are heated and allowed to cool, a test tube is taken and the clarifying liquid is poured out.

"Okay, second brother, take a closer look, it's time to witness the miracle." Abu said to Liu Yuanlu with a smile on his face.

I saw that he placed the round glass on a stand, evenly coated the glass with the three solutions he had just obtained, and began to use an alcohol lamp to move underneath to heat it evenly.

When the liquid on it dried up, the top layer of the clear glass that had been cleaned just now was covered with a gray-brown coating.

After the glass cooled, Abu said to Liu Yuanlu: "Second brother, you can turn it over and take a look." ”

Liu Yuanlu picked up the glass on the stand, turned it over and looked at it, and was startled. Seeing that there was a person's head inside, wearing a scarf, a slightly thin face, and a lock of long hair, who else could it be if it wasn't him? The wrinkles and beard on the face are clearly visible.

"Mirrors?" Liu Yuanlu couldn't help but scream, this was the first time in his life that he saw his appearance so clearly.

"Haha, how's that? It's pretty clear! ”

"Third brother, tell me quickly, how did you do this?"

Abu didn't talk nonsense, took a piece of paper, wrote down a few formulas with a brush, and said to Liu Yuanlu: "You are familiar with some of the reaction formulas here, and you can study the rest slowly, and then talk about it after you have any questions, I still have to make a frame." ”

Liu Yuanlu looked at the formula on the paper, immersed in it, and didn't even pay attention to Abu's farewell greeting.

In the evening, Yun Niang was cooking at home, and Abu walked in from outside and said, "It's so fragrant, what's delicious?" ”

"Where there is, it's not the same as usual."

"You should have made something delicious, have you forgotten what day it is?"

"What day?"

"You fool, it's your birthday!"

"Really? It seems like today, I'm about to forget, it's been a long time. Yun Niang replied lightly.

"Alas!" Abu sighed, "I've spent nearly a day preparing a birthday present for someone, but some people don't seem to be able to lift their spirits. ”

"Huh? There's also a birthday present, so bring it to me. ”

"Forget it, looking at someone's appearance, I'm not very interested."

"Hurry up and bring it, do you still want to eat?" Yun Niang said angrily.

Abu took out a square box from behind his back and put it in front of Yun Niang with both hands: "Dangdangdang!" Happy birthday, little beauty! But be careful, don't break it. ”

Yun Niang put the box on the table and gently opened the lid, and inside was a piece of red silk.

The silk cloth was lifted, and a round object was quietly placed inside, covered with a red silk cloth base, surrounded by a smooth white wooden frame.

When I turned it over, it was a peerless beauty with a high bun, her eyebrows were like a moon, and her face was like a peach blossom.

Yun Niang's reaction was the same as Liu Yuanlu's, and she cried out in amazement: "Mirror! It was the first time she had seen herself so clearly.

Yun Niang turned to Abu, saw that he was looking at herself with a smile on his face, remembering that he had disappeared for nearly a day, and it turned out that he had made this birthday gift for himself with his own hands, and a tenderness suddenly surged in her heart.

She put down the mirror, threw herself into her arms, and kissed Abu, Abu hugged Yun Niang with her backhand, and for a while, she was in love with a concubine, and the room was full of spring.

I don't know how long it took, when Yun Niang's face was flushed, and she left Abu's arms like a bright Danxia, she suddenly called out with an "ah", and saw Wu Ye standing at the door, I don't know how long she had been standing.

Seeing that both of them looked over, Wu Ye asked weakly, "Master, sister, what were you doing just now?" ”
