A large number of industrial raw materials are used to make soda ash in the fairy world, even if it is the simplest method to produce a lot of poisonous gas, concentrated sulfuric acid is also used, concentrated sulfuric acid is more complicated to do, and it is a burning mineral and catalytic concentration, and it is extremely dangerous. ”

This method only requires the subordinates to go to the chamber of commerce to collect the grass Artemisia knotweed, take it back and soak it for a period of time, then dry it, burn it to ashes, and filter the ashes with water to get a mixture of soda ash, and the required things are in the filtered water.

Li Ruixiu flipped through the books prepared at home and found the source of this paragraph, which was written on the back of "two or three catties of flour per hundred, and it will be condensed like a stone for a long time, even the juice of the Quartet, and the face of the clothes will be very profitable".

Li Ruixiu felt that his eyes lit up, since the folk have used this method to manufacture flour laundry products in large quantities, then why should he go to produce it himself, there is no need to be so troublesome, Li Ruixiu directly asked Liu Fu to go to the mountain to find merchants again to buy the intermediate things of stone alkali, and the black semi-finished products before adding flour, that is, plant ash, took them back and filtered the crystallization by themselves. Li Zhan is not an honest person, the weather is freezing in the past two days, he can't bake the fire at home, and he has to run back and forth with Liu Fushan in the city, begging to go to the door and being rejected by merchants from all walks of life, the personal servant of the Sanpin Emperor went to the white eyes of the merchants with silver, and even the arrogant Chinese army dared to be angry and unspeakable at his own house, he really didn't understand why his adults wanted to buy those useless coke, ores, and rotten saltpeter at this stall, the mountain was already cold and dripping into ice, and his master still had to make ice!

Li Zhan had just gone up the mountain with a cold wind and returned to the ceremony, he didn't get the reward, and he had to be sent down the mountain early tomorrow morning to buy some plant ash, this thing didn't have to get those poor and remote mountains to find a workshop, Li Ruixiu was still in a hurry, and when he thought of something, he had to get it in his hand immediately, urging them to go early and return early.

Li Zhan simply had a heart, and went to the treasury to get a charcoal stove, tomorrow he will go down the mountain, what should Liu Fu do with that fool, he himself must be warm and lively, he complained in his heart, who is the little guy in front of him to do this, even if he runs errands diligently, it is also between the Gaomen compound, the strangest thing is that this horse master just puts the house in the city and does not live in the mountain, he lives spaciously, poor donkey at home, from one to three, and he can't breathe, and he has lost a lot of weight in vain.

Li Ruixiu naturally didn't know the complaints of inferior people, he was not a girl, he had never learned housekeeping, he used to just study hard, and now he was concentrating on his chemistry laboratory. Once he has soda ash, many of the problems that plagued him before have been solved, even the generator can be refined and modified, and the lampshade can be clearer and brighter.

Li Ruixiu asked people to go to the back mountain again and said that he wanted to open a kiln to refine the glaze, and asked those craftsmen which one had the skills to burn the kiln. When the craftsmen heard that Li Ruixiu wanted to employ people, they were very excited, although they could not leave the military affairs, they could contact people they knew, such a good opportunity, they could get in close contact with the immortals, and the remuneration was also rich, so they had to fight for their own family and village.

The smelting of steel and the high-temperature kiln are still different, Li Ruixiu directly planned the high-temperature kiln next to the steel workshop, and the courtyard on the mountain was three into the courtyard, but the third one could not be used, and the front yard was also full of people, so Li Ruixiu planned an area next to the workshop in the back mountain to build a few houses for the craftsmen to live.

It's another sum of money to spend out, and the steward who saw it was staggered, other adults love to buy antique powder, and they spent a lot of money for those things, and they were said to be losers, how can they compare to this adult, they spent a lot of money to buy these clay tiles and stones, and boxes of silver tickets were carried into the glaze factory, and they didn't hear a sound, but they were busy supporting people to buy grass and wood ash, which was to raise the price of soap, Liu Fu hadn't come down the mountain at this time, and it was rumored in the house that he was looking for a craftsman to build a house and a high-temperature kiln, and he looked like he was going to burn porcelain. I really don't know where this adult has come up with so many things in the room all day long, the big Dan furnace in the warehouse is pure copper, and now it is useless and just puts ashes......

Li Ruixiu saw that the sky was completely dark, so he stopped the design, ready to set the meal, was so noisy by the Chinese army, all his plans were stalled, but a little leisurely, after dinner, Li Ruixiu left three younger siblings, the charcoal fire in the house burned well, and he happened to communicate with a few children.

Li Rui said: "Mr. Nan has also started classes in recent days, which book did you learn today?" ”

Li Ruijie said first: "Mr. talked about "University" again, only the first paragraph, and talked about three outlines and eight eyes. ”

Li Ruixiu asked: "Why did you talk about the university chapter again, but there is something to gain?" ”

The university chapter is the first of the four books, in the past in the Li family, the first official study is the university, Li Ruixiu can't understand how Mr. Nan talked about the university again, and talked about the first paragraph for a whole day.

Li Ruixin said: "Although I re-studied the university, but after reading the four books, I also have some feelings, re-read the three outlines and eight goals, and the books learned in the past also have a feeling of being connected, although the eight eyes are classified, but now I still feel that there is a tendency to inherit, my brother thinks that it is based on 'righteousness', only righteousness, in order to 'self-cultivation', and righteousness, naturally can 'sincerity'. ”

Li Ruixiu thought for a while and said: "The eight purposes are indeed both internal and external, and self-cultivation is the most important, I think Mr. Nan also intends to re-point it for you, and then I will re-explain the four books in detail." ”

Li Ruijie said: "Mr. did say that he would re-teach the four books, this time not by bibliography, but by cross-teaching, so that the two of us could memorize the contents of the books in class." Li Ruixiu nodded yes, and then remembered the teaching content of the fairy world, which is based on "morality, intelligence, physical fitness, beauty and labor", and attaches great importance to mathematics, physics and chemistry. Li Ruixiu heard Li Yujiao's giggles, blindfolded and didn't know what was going on, but he thought of such a little girl, and it was really interesting to listen to Mr. Nan talk about big things in the study all day long.

He suddenly became interested and asked, "Let me ask a partial question, I know that the two of you are willing to read some miscellaneous books on weekdays, and you can memorize the ninety-nine multiplication songs." ”

Li Ruixin said with a smile: "I followed it when I was a child, but now I haven't seen it for a few years, but when Brother Xiu wants to ask, I suddenly think about it." After that, Li Ruixin memorized the song.

Li Ruijie can also memorize it, but he didn't answer, he looked at Li Ruixiu, he didn't see any expression on the other party's face, thinking that people were talking about King An's anger and leaving his mansion, and there was a conflict with the eldest brother, so the eldest brother is going to turn to business now? After all, he was still young, and he suddenly lost his parents and family, and he vaguely felt the crisis in his family, and he couldn't help but feel sad and depressed.
