Queen Mother's A Scientist

"Time is too tight. The queen has sent three consecutive instructions. I'm afraid your Majesty's time is running out. The imperial court needs the prince to go back and preside over the overall situation as soon as possible. We can find a way to take her out of the city after rescuing the prince. At that time, it's just a woman. We don't have to be afraid of hands and feet like now."

Old Qin nodded, "well... What elder brother said is reasonable. Now the most important thing for us is to send the prince out of the city... Hey, I don't know whether uncle Liu has taken care of it properly."

Fu tingye hears the speech, his eyes become erratic and looks out of the window——

The outside scenery is gray, with layers of snow and cold.

"At the beginning of the Liao army, Zhanxi, hehe and mozhou, from the state to the government, city, town and village... Whether it's judicial institutions or miscellaneous procedures, they need to be connected one by one. This layer sets up one by one... It's time-consuming and laborious to manage..."

Once he thought that the land under his feet was changing silently, Qin Laowu couldn't help being silent.

"I hope this trip will be smooth..." Qin Laowu said.

……

When it was slightly bright, Hua Qingxue got up.

Li Jingnan rubbed her eyes and watched Hua Qingxue climb out of the warm quilt.

God

The sun came out in the west?

When don't they get up every morning?

There's no way. It's too cold. Even if you wake up, you have to squeeze into the quilt and stare, and then wait until the sun shines on your ass, and then climb out to bask in the sun.

Hua Qingxue puts on clothes one by one.

She has been foolishly unable to distinguish the inner clothes from the outer clothes in ancient times. Li Jingnan has pointed out several times. Every time she doesn't get distracted. Finally, she only remembers that it's always right to wear light colors inside and dark colors outside.

It was too cold, and the clothes were cold. Only a single coat covered in the quilt in advance was warm.

"There were still some steamed stuffed buns left yesterday. You can bake them in the stove later. I requisitioned the pot." Hua Qingxue said to Li Jingnan in bed as she braided her hair.

There was only one person's quilt. It seemed that it was not as warm as before. Li Jingnan tilted her head on the Kang and asked her, "what are you doing?"

Hua Qingxue was in a good mood and smiled, "I went to make soap. Didn't I say it yesterday?"

Li Jingnan stared at Hua Qingxue like a madman, "do you say fragrant pancreas? Do you know what the pancreas does? "

Although Li Jingnan does not divide grains, he also knows that fragrant pancakes are not something that ordinary people can afford, just as not everyone can afford white rice.

Hua light snow smiled and shook his head. "I can't do it with incense. I don't have any spices and flavors on hand. I can only make plain ones, but it must be better than what you used to do, and I bought sulphur, so we can make sulphur soaping out, uh! I'll make more and sell them. I won't be afraid of starvation in the future! "

Hua Qingxue said, picked up the pot behind the door and some things purchased yesterday, and went to the yard happily.

Li Jingnan naturally stopped sleeping. He was very curious. He got up quickly, put on his clothes and shoes, and ran to the yard.

Hua Qingxue was pouring quicklime into the pot. Seeing Li Jingnan running out to join the fun, she smiled shyly, "I don't know if I can succeed... In principle, it shouldn't be a problem, but there's no measuring cup and measuring tools on hand, and the weight can only be estimated."

Li Jingnan looked at the things in the pot and asked, "is it time to start making pancakes?"

"Not yet. I need to get out the sodium hydroxide first..."

"Ah? What is that? "

"The ingredients of soap are sodium hydroxide and oil. As long as you get sodium hydroxide, the later things will be easy to do."

After listening, Li Jingnan just seemed to know something but didn't understand it. He urged, "then hurry up, I want to see it!"

Hua Qingxue was very patient. She explained while operating: "we first need to calcine quicklime, and then add water... You see, this will become lime slurry. The chemical composition of lime slurry is... Forget it, you can't remember. In short, mirabilite is added at this time. Um... This amount of mirabilite is probably needed for so many lime slurry..."

"Ah! Blistering! Bubble! " Li Jingnan saw a reaction in the pot and shouted!

"Don't get so close!"

Hua Qingxue pulled Li Jingnan aside. He still stretched his head into the pot and said, "Hua Qingxue, are you refining pills..."

Hua Qingxue: "

Well, in fact, she thought, ancient chemistry really began with those alchemy Taoists

"These two things are undergoing double decomposition reaction. Together, they will produce calcium carbonate precipitation and sodium hydroxide."

"Where? Where? "

"Well, now the precipitate in this pot is calcium carbonate and the other is sodium hydroxide. It's easy to divide. There's no need for secondary filtration."

Li Jingnan looked suspiciously at the unidentified object in the pot and Hua Qingxue. His expression was very puzzling, "can this make a pancreas?"

Hua Qingxue nodded definitely, "Hmm! I'll clean it up. You go inside and get the oil. "

"Good!" Li Jingnan excitedly went to the house and soon came out with an oil pot.

Hua Qingxue carefully separated the sodium hydroxide from the sediment in the pot, poured the sodium hydroxide back into the pot, scooped a spoonful of water from the bucket and slowly mixed it into the pot.

There was a violent reaction in the pot immediately, and layers of smoke came out of the pot!

Hua Qingxue had already prepared and immediately covered her mouth and nose. Li Jingnan also covered half of her face. In the end, it was difficult for the child to get rid of sex. She secretly opened her mouth and took a breath in the middle of the way. She was choked to runny nose and tears immediately!

Hua Qingxue can ignore him at this time. He wraps a thick cloth in both hands, holds his breath, grabs both sides of the pot, carries it up, and puts it into the prepared basin, which will submerge half of the bottom of the pot.

"Sodium hydroxide will produce high temperature and smoke when it meets with water, but it's only about a minute. Now let's cool it down."

"Then you can make a pancreas?" Li Jingnan wiped her nose and asked her.

Hua Qingxue shook her head. She waited quietly for a while, reached out and carefully touched the outer edge of the pot. Now in winter, the temperature is fast. With cold water, the pot is not so hot.

When it's about 40 degrees and warm, you can refuel.

"Huh? Where's the oil I asked you to take? "

Li Jingnan then pointed to the oil pot on the side.

Hua Qingxue immediately slapped him on the ass!

"This is our own oil! I asked you to take the waste oil that Aunt Yan gave us! "

Restaurants and restaurants always leave a lot of waste oil every day. After countless times of frying, these oil is mixed with the residue of many ingredients. The color is brown and black. It is no longer suitable for eating.

Waste oil doesn't cost a penny. It's most suitable for making soap.

Li Jingnan took a hit, frowned and muttered "I'm the Prince", then shrugged and trotted back to the house to pick up the waste oil Hua Qingxue said.

Hua Qingxue adds oil to the thoroughly dissolved sodium hydroxide, and takes long chopsticks to stir while adding it. When the stirring is tired, Li Jingnan will do it.

"Don't change direction, always follow one direction."

Two people, you change me for a while and I change you for a while. After stirring for about a quarter of an hour, the things in the pot have become like milk tea, and there are no oil filaments on the surface.

Hua Qingxue takes out several sea bowls, puts them in a row beside the pot, and pours the things in the pot into the bowl one by one. After all this, Hua Qingxue clapped her hands and said, "OK! Put it under the eaves where the sun can't shine. It can be dry tomorrow, and then it can be cut into small pieces. "

Li Jingnan looked forward, "can you become a pancreas tomorrow?"

Hua Qingxue smiled, "Hmm! But I have to wait a month before I can use it. The longer it is put, the harder it is, the better it can be used! "

Li Jingnan was stunned“ What are you doing! How could those Liao soldiers wait for you for a month?! "

Hua Qingxue turned to look at him and said, "I didn't intend to wash those military clothes with my pancreas..."

It takes a long time for soap to be easy to use. One month is the shortest time estimated by huaqingxue. Even in the era of modern industry, the best sales time of handmade soap is three to six months after it is made.

Of course, if the soap products are produced in batch by machines, there is no need to wait so long, and the price will be much lower than that of manual soap.

The price of goods is always closely related to two things, one is whether its materials are scarce, and the other is the time-consuming process.

Li Jingnan sometimes really feels a headache for the slow brain circuit of light snow in China!

He said anxiously, "since these things are not used to wash clothes... What are you doing with so much effort?! You are not afraid to wash your clothes. Will they give you a knife? "

He wanted to say: what time is it now! Why do you still have time to make pancreases? Ah?!

Hua Qingxue is not slow. She is very smart. She always has countless inexhaustible scientific knowledge in her mind, but the problem is - her thinking and cognition are different from Li Jingnan.

She must find a way to settle down here as soon as possible, so that she can live well after escaping with Li Jingnan.

Ren Qiu is too chaotic here. She hasn't had an accident so far. Except that she is very careful, she is more lucky.

Chaotic public security, erratic prices, and the tense and depressing atmosphere in the city all the time make her want to go out of the city all the time

Hua Qingxue began to clean up the pot and prepare another pot of soap mixed with sulfur. He replied to Li Jingnan: "they don't need this for their clothes. They just need to dip the potato powder with vinegar and apply it directly to the place with blood stains. When the potato powder is dry, rub it gently, and the blood stains will be rubbed off with the potato powder... If it's not clean, It's enough to rinse the rotten radish with boiling water. "

Li Jingnan stared, "is it so simple?"

Hua Qingxue reluctantly stood up, "otherwise how difficult do you think it can be?"
