After the prosperous Tang Dynasty

The sky outside the window gradually darkened, and after Xiao Yansui had dinner with her mother and two elder brothers, she got up and went back to her yard.

Mrs. Pei was still worried, and touched her daughter's damp hair, fearing that she would be left to dry in the yard, so she took a cloak with a hood and put it on her, while gently and meticulously arranging the skirts of her daughter's clothes, while still He still said softly with a bit of reluctance: "Are you really not going to stay here with A Niang?"

Even Xiao Heng and Xiao Wu looked at their sister with concern and worry.

As a key person who has attracted everyone's attention, Xiao Yansui only felt a lot of pressure, continued to shake his head firmly, and then showed a shallow smile, and said in a soft and coquettish voice: "Don't worry, Ma'am, I'm really fine .”

Mrs. Pei sighed softly, and warned again: "When I go back, the wound on my hand will need to be re-medicated, and even if I fall asleep, I should be careful, Axiu, pay more attention tonight. some."

A Xiu hurriedly nodded in agreement.

Even so, Pei Shi was still worried, so she simply called a maid named Yunxia beside her to take care of Xiao Yansui's courtyard first.

Axiu carried a lantern and walked in front to illuminate it. Xiao Yansui's figure fell in the shadow of the lantern. Playing together, she deliberately stepped on the shadow of the lantern and followed closely with brisk steps.

Seeing this, Yunxia froze for a moment. She wanted to speak out to dissuade her, but unexpectedly she was already behind, so she had to take a few steps in a hurry to catch up.

After returning to her courtyard, because Xiao Yansui had been dozing off before dinner, the first thing Axiu did after entering the house was to make the bed.

Yunxia paused for a while standing beside her, then immediately followed up to help.

Xiao Yansui sat on the low stool next to her, looked down at her hands wrapped in steamed buns, turned her eyes, looked at the various porcelain utensils and other things on the museum shelf in her room, and began to think, The feasibility of tinkering with a set of simple distillation equipment using only the things in one's own house.

——Although the medicine she is applying on her hands is good medicine for hemostasis and muscle growth in traditional Chinese medicine, but when she washed the wound with clean water before, just to be on the safe side, Xiao Yansui couldn't help but think that she should prepare Some daily necessities such as cleaner distilled water for removing impurities, and alcohol for disinfection...

Xiao Yansui got up, walked to the table, and took out a quill from the pen holder—this was a few goose feathers she had asked a carpenter to polish before, and then plucked them from the ingredients in the kitchen. It is fixed inside the hollow pen holder.

Although the overall design of this quill pen is very rough, it is still no problem to temporarily dip some ink to write a few calligraphy and paintings. Especially at this time in the Tang Dynasty, the quality of the paper is not comparable to that of later generations. In order to prevent the feather rod from clogging, Xiao The ink Yan Sui used was diluted with water, so that the handwriting would be more easily stained on the paper. However, her hand hurts now, and she can hardly hold anything, so she can only hold the pen holder. Lightly sketched two rough drafts of experimental equipment diagrams.

"Liu Niang?" After making the bed and putting down the veil beside the bed—actually it was a slightly thicker mosquito net, Axiu and Yunxia walked over, wanting to take care of Xiao Yansui to rest.

Xiao Yansui, who was halfway drawing the simple version of the alcohol distillation experimental device, paused for a moment, put away the drawing, and disassembled the experimental device into scattered equipment.

A casserole that can be heated by fire, and a teapot that is a circle smaller than the casserole and can be heated in a water bath, these two can be put together to replace the round bottom flask in the laboratory.

Then remove the bottle body and leave only a long strip, which is equivalent to a condenser. However, the narrow neck of the ampoule cannot be like a condenser. There is water between the double-layer glass to cool down. Xiao Yan Sui planned to directly wrap a layer of half-inch square ice cubes on the narrow-necked bottle with gauze bag, and then continue to add ice to it before all the ice cubes in the gauze bag completely melted. That's it.

As for the water outlet, there is no need to think about the vacuum connection tube or anything, just take a bottle and connect it to the neck of the ampoule.Although the alcohol itself is easy to volatilize, it is impossible to achieve a closed vacuum distillation, and the final alcohol content will be less.

And to be honest, shochu itself is a mixture, and the product directly distilled from shochu is still a high-concentration wine rather than alcohol, and the ethanol content will be far lower than 95% of industrial alcohol.

After all, all she can find at hand is simple equipment, not even a thermometer, so she can only rely on her senses, so she can't be too demanding on the experimental quality of this rough experiment, anyway, she needs to use it for disinfection The content of medical alcohol is 75%. Now there is no way to make an accurate ratio, and we can only make a rough estimate. Even if it is a high-concentration shochu, it can be disinfected better than nothing...

After Xiao Yansui drew the diagram of the equipment she needed, she handed it over to Axiu, and said: "Prepare these things tomorrow, I want to use them."

As she spoke, she was already so sleepy that she yawned, and soaked the quill in her hand in a cup filled with clear water beside her. The black ink stains instantly melted in the water, drifting apart like wisps of smoke. .

"I'm going to rest." Xiao Yansui blinked her eyes. After she pulled herself together and finished drawing the experimental equipment, she became sleepy now. She couldn't help but want to close her eyes while she was still sitting in front of the desk.

Axiu took the list, although she didn't know why, but she had been by Xiao Yansui's side all the time, and she also knew that Xiao Yansui liked to tinker with weird things on weekdays. The child's toy was gone, and he nodded and said: "The maidservant has recorded it."

Yunxia happened to catch a glimpse of the list in Axiu's hand, and frowned in confusion. Thinking that there were ice cubes, a casserole pot, and a ampule that had been specifically declared to be broken, she felt in her heart that it shouldn't be allowed to let a small The child was playing with these dangerous things, but Axiu, the maidservant beside Liuniang, didn't seem to think there was anything wrong with it. For a moment, looking at Xiao Yansui and Axiu, Yunxia opened her mouth, looking hesitant to speak. appearance.

Xiao Yansui turned around and was about to walk towards the bed. Axiu held the list in her hand and hurriedly said again: "Liu Niang, the wound on your hand needs another medicine."

"Oh, yes, and this matter, I forgot about it." Xiao Yansui muttered casually, stopped, sat back on the low stool, and obediently stretched out her hand.

Yunxia was still hesitating, because she was Pei's maid, so naturally Axiu would not order her around.After putting away the list that Xiao Yansui had just made, Axiu took the medicine and the bandaged gauze from the box by herself, then gently unwrapped the bandage on Xiao Yansui's hand, and re-wrapped it for her very carefully. Prescription.

Xiao Yansui looked at Axiu's meticulous movements, and was a little distracted. Thinking of what happened when he took a bath just now, he thought that tomorrow he could use shochu to distill out the less pure alcohol, just right, to make soap In fact, we can do it together.

After briefly reviewing the experimental principle of saponification reaction in chemistry and the experimental equipment needed, Xiao Yansui yawned lazily and continued: "By the way, help me prepare a few more bottles and cans tomorrow." Yes, it doesn’t need to be too big, and you need some lime or something—forget it, let’s talk about it tomorrow morning!”

She had just finished applying the medicine to her hand, so she didn't plan to touch paper and pen again tonight, and she had to recuperate and rest first.

"Yes," Axiu's movements were gentle and delicate, but she still obediently agreed in her mouth.

"...What does Liu Niang want those things for?" Yunxia, ​​who had been standing by the side, finally couldn't help persuading, "They are all rough things used by craftsmen in their work. They can't be used for much, and they are easy to accidentally hurt themselves. ..."

Xiao Yansui blinked, but said nothing.

A rough thing that can't be used much?Among other things, lime is definitely a milestone in the history of architecture, although in her eyes, lime is more often an object whose main component is calcium hydroxide. The main feature of calcium hydroxide is white, solid, difficult to It is a common chemical material that is soluble in water, the aqueous solution becomes alkaline, has water absorption and can be used as a desiccant, can absorb carbon dioxide in the air and then convert it into calcium carbonate...

Seeing that Axiu was about to bandage him up, Xiao Yansui said softly, "Axiu, take Yunxia to rest too!"

Axiu nodded in agreement, but Yunxia was slightly startled again.

When Pei asked her to come, she must be worried that her daughter would be injured. The only maidservant around was Axiu, so she asked her maidservant to help.Yunxia originally thought that she and Axiu would be the ones taking care of Xiao Yansui tonight, but no matter what she meant now, she was asked to go elsewhere...

After Xiao Yansui lay down on the bed and closed her eyes, and Axiu helped her put the veil back, she was about to go over and blow out the lamp, but seeing Yunxia standing there motionless, Axiu couldn't help but said, "Let's go, I'll take you to sleep outside."

Yunxia hesitated, and murmured in a low voice: "My lady asked me to take care of Liu Niang..."

Axiu turned her head away, rolled her eyes secretly, curled her lips, took Yunxia's hand flatly, and urged in a low voice: "Liu Niang doesn't like to have other people around when she sleeps, don't delay Liu Niang's rest here." .”

Immediately, Axiu turned off the lights in the room without any explanation, and took Yunxia out.

The light and shadow in Xiao Yansui's room dimmed instantly, and through the gauze window, one could vaguely see the cool moonlight outside.

Last night because of the nightmare, he didn't have a good rest, and today he was kidnapped again. Xiao Yansui was also exhausted physically and mentally. He lay on the bed and soon closed his eyes and fell into a deep sleep.

And in the main house, Mrs. Pei, her husband Xiao Hua, and Princess Xinchang sat aside, and Mr. Xu Xiao Song sat at the main seat. After listening to Mrs. Pei's account of what happened today, he slowly counted a string of beads in his hand , looking thoughtful.

"Ah Weng, Liu Niang, a child who doesn't like to go out and play with others, how could she provoke such hatred. The people behind the scenes obviously have other plans." Pei said softly.

Xiao Hua also said: "This matter is no small matter, I am afraid that someone is eyeing the Xiao family——"

"It's still too early to say anything at this time." Xiao Song looked at his eldest son and daughter-in-law calmly and gently, and said in an extraordinarily calm voice: "Check, this matter must be investigated to the end! Granddaughter, why have you ever been wronged like this! Tomorrow I will tell the saint that Ximing Temple is a pure place of Buddhism, how can you allow thieves to hide there and do such crazy things!"
