Priceless: A widow with a baby asks the prince to marry again

The second distillation was very fast and was completed in about quarter of an hour, producing more than three kilograms of liquid. At this time, the pungent smell of alcohol could already be smelled.

Before starting the third time, Liu Rusi took a little alcohol with a small spoon and placed the spoon in a basin filled with yellow mud. She asked Chu Shiyu to bring a lit twig.

"Try tapping it on the spoon." Liu Rusi instructed. She was too lazy to argue with him about such small steps. Let him do it if he wanted.

Chu Shiyu quickly lit the burning twig on the spoon, but the fire on the twig did not go out as he expected! Even when the twig left the spoon, he saw a light blue flame on the spoon!

"What's going on?" The fact that alcohol can burn was a little beyond Chu Shiyu's understanding.

Yes, after more than two hours of busy work, Chu Shiyu had his own guess about what was being made. The disinfectant that Liu Rusi mentioned should actually be a very strong liquor.

"Ethanol, the main ingredient of disinfectant, is a flammable substance that can be mixed with water. It can burn when the proportion of ethanol is slightly higher than that of water. The higher the proportion of ethanol, the more intense the combustion."

Liu Rusi began to perfect her theory that disinfectant water cannot be drunk: "Because of the properties of ethanol, if you drink disinfectant water, you will feel a strong burning sensation, which will harm the esophagus and stomach, and will spread to the blood. When people consume too much ethanol, it may cause poisoning and death."

Chu Shiyu nodded and took note. He still thought it was strong liquor, and it was unknown whether it was really what she said. However, even if it was just to reassure her, he would insist that it was disinfectant in the future, and emphasize like her that it could not be drunk.

When conducting the final distillation, Liu Rushi put out all the newly fired alcohol bottles, and this time the alcohol content was just right.

Compared to the first distillation, which had a light yellow tint, the last dripping liquid was almost as clear as water.

When the bamboo tube almost stopped dripping liquid, Liu Rusi gently fanned and smelled the large bottle that contained the liquid. In an instant, she was so irritated that she closed her eyes and quickly stepped back. The degree of stimulation was definitely too strong!

"Rusi! What's wrong?" Chu Shiyu hurriedly pulled her back a little.

"It's okay, I'm fine... the smell is just too strong." Liu Rusi blinked and recovered, then said, "Go and light up the fire and boil the water in the pot. I want to lower the ethanol concentration."

Chu Shiyu looked her up and down carefully, and seeing that she was really fine, he once again warned her seriously: "You know the dangers here better than I do, don't hurt yourself!"

"Don't worry, I'm not a fool."

Liu Rusi estimated that the alcohol now was about 90 degrees or more. There were two kilograms of alcohol in the bottle. The goal was to reduce it to 15 degrees, so she needed to calculate how much distilled water to add.

She wasn't that good at mental arithmetic, and there was no pen or paper in the kitchen, so she used a piece of charcoal near the stove to calculate the density of ethanol and the density of water, and then figured out the ratio of ethanol to water, and then calculated how much distilled water to add...

"What are these?" Chu Shiyu looked at the string of unfamiliar symbols on the ground in surprise.

Liu Rusi suddenly woke up. Was she drunk? She was actually writing Arabic numerals in front of Chu Shiyu! She used to make alcohol with Qin Lie, and she had taught Qin Lie numbers and symbols. She forgot to be on guard for a moment...

After pondering for a while, she came up with the calculation results and said as calmly as possible: "These are some simple symbols that are easy to calculate. I can teach you when I have time after the disinfectant is made."

Chu Shiyu nodded silently, hiding his inner surprise. When he heard her say "I don't belong to this world" that day, he now had a more real feeling...

The water in the pot began to boil, and soon the condensed bamboo tube dripped liquid again, but the difference was that some water vapor was still pouring out of the tube. This was because the water vapor temperature was higher and the condensation temperature of the bamboo tube was not low enough.

Liu Rusi immediately got several cold rags to wrap the bamboo tube to cool it down, and kept changing the cold rags. This was a temporary remedial measure.

Seeing Liu Rusi busy as a whim, Chu Shiyu just looked at her with concern and did not try to dissuade her.

Did she have any other pursuits besides raising Qin Hao? He had never noticed that there were any before, so he just wanted to put her in a safe and comfortable place, without suffering and enjoying glory.

But now that I think about it carefully, with her intelligence and character, is it really possible that she doesn't have any deep-seated ideals in her heart?

After a lot of hard work, I finally got a small bottle of distilled water... But that was enough. After mixing evenly, the production of disinfectant was finally completed!

"I'll put the disinfectant into the small bottle, and you put the cork on it." Liu Rusi had a relaxed smile on her face, and her tone when speaking to Chu Shiyu was much warmer.

The twelve small square bottles were all cleaned and disinfected with hot water, and then placed one by one. Liu Rusi put the small funnel into the mouth of the square bottle, picked up the large porcelain bottle filled with alcohol, and poured it in at a constant speed with great effort.

Chu Shiyu observed how full she needed to fill it, and quickly put the cork in. He stepped forward and took over and said, "The big bottle is quite heavy. Let's change it. We spent so much effort to make it, don't let it spill."

This made sense, so Liu Rusi changed jobs without hesitation.

His hands were really very steady. He could pour the alcohol just to the mouth of the bottle. Liu Rusi then deftly put the corks on and pressed them tightly one by one. These corks were provided by the porcelain factory, so naturally a set of things would fit perfectly.

When the twelve newly fired small porcelain bottles were all filled, Chu Shiyu picked up the large bottle, shook it and weighed it, and estimated that there was still enough for two small bottles left in the large bottle.

"Don't you want these anymore?" After all, these were the fruits of his labor in which he participated throughout the entire process. Chu Shiyu felt it would be a pity if they were thrown away.

Liu Rusi naturally felt it was a pity. There were three old bottles in the medical box, which still contained alcohol. However, the wax seal of one of the bottles was damaged. Normally, alcohol could be stored for a long time, but the bottles had been soaked in floods.

"Put the big bottle aside first, I'll ask you to look at something." Liu Rusi picked up an old bottle and gestured to Chu Shiyu. It would be a pity to pour out the old alcohol directly, so it would be better to give Chu Shiyu a safety education.

Chu Shiyu nodded with interest and watched Liu Rusi open the damaged old bottle of beeswax, then find a cotton rope and dip it into the bottle, leaving only a section of the cotton rope that was gradually soaked.

Before Liu Rusi took the burning branches to light the fire, Chu Shiyu asked speculatively: "Use disinfectant to make a lamp?"

"Well, but it should be called an ethanol lamp. It can be called disinfectant only when it has a certain concentration, and the higher the concentration of ethanol, the more suitable it is for lamp fuel." Normally it should be called an alcohol lamp, but Liu Ru thought of weakening its connection with wine. At least the people of Daxia who have not studied chemistry would definitely not think of ethanol as wine when they hear it.

The small branch easily lit the cotton rope wick. Now that the sky was dim, the flame of the ethanol lamp seemed bright.

"The flame is slightly blue and not as bright as a candle, but it seems to produce no smoke and feels much more refreshing." Chu Shiyu observed the flame.

"This is because the concentration of ethanol is low and the combustion temperature is also relatively low. However, the temperature of this flame is enough for disinfection. I sometimes use this method to remove dead air attached to utensils."

Liu Rusi took up a small knife and burned the flame of the lamp for a few breaths as if to demonstrate. In this era, it was too much to talk about bacteria, viruses or something like that. The idea of ​​death energy was in line with the characteristics of the times. Anyway, she currently had the right to interpret death energy.

"It seems good to use it as a night light." Chu Shiyu considered the practical value of the ethanol lamp.

"Um... so much wine was used and a lot of firewood wasted to make just a few bottles. Isn't the cost of making a night light too high..."

Just buying twenty kilograms of muddy wine cost Liu Rusi two taels of silver. If the lights were kept on at night, the alcohol made here would be used up in one night! How is this different from burning money?

Liu Rusi noticed that Chu Shiyu seemed a little unconvinced. She suppressed her sour tone, coughed lightly, and turned to the main topic, saying: "No matter what the purpose is, fire safety is the most important."

She pushed the burning alcohol lamp into the copper basin, and then the flame spread throughout the copper basin along with the alcohol! The temperature in front of her also rose sharply!

Chu Shiyu quickly pulled her away again and frowned, "What are you doing? Be careful or you'll get burned!"

Liu Rusi ignored his nervousness and continued to explain: "If ethanol catches fire, it cannot be put out directly with water."

Then she scooped a cup of water from the side and poured it into the burning copper basin. The flame was not affected at all. Instead, it seemed to become more intense because of the expanded area.

"Then how do we put it out?" Chu Shiyu sighed helplessly and cooperated with her teaching.

Liu Rusi nodded with satisfaction, and went to get half a basin of fire-proof sand that had been prepared long ago and poured it into the copper basin. Needless to say, the fire was completely out.

Then she explained seriously: "There are three principles for extinguishing fire: one is to remove and isolate the flammable materials; the second is to lower the temperature of the burning materials; the third is to isolate the air. Using sand to extinguish fire is to isolate the air."

"When using an ethanol lamp, you cannot blow it out like a candle, otherwise it may cause a fire! The correct way is to use a small airtight lid as a lamp cap, and then you can turn off the lamp by covering it."

Chu Shiyu listened humbly, and then asked: "Why didn't you prepare a lamp cap?"

"I forgot it at home..." Liu Rusi said expressionlessly. She did have it at home, but she rarely used it because she couldn't bear to spend it lavishly. She didn't even think of taking it when she packed her luggage...

After the safety education, Liu Rusi emptied two old bottles and used old alcohol to disinfect the three bottles several times. The outsides were contaminated by the flood.

The remaining disinfectant was just enough to fill two old bottles. This feeling made Liu Rusi happy.

"Are you done now? Dinner time has already passed half an hour." Chu Shiyu saw that it was already too dark outside the kitchen to see clearly.

"One last thing, seal the bottles with wax for long-term storage."

Liu Rusi felt a little apologetic for making him busy in the kitchen for three hours, and then suggested, "Sealing wax is very simple, why don't you go eat first, and I'll come over when I'm done."

"Since it's simple, let's finish it together." Chu Shiyu firmly rejected her proposal. He was indeed a little hungry, but even if he had been hungry for a whole night, he would never leave her to eat first.

"Okay, watch me make a bottle first." Liu Rusi instructed Chu Shiyu to take out the beeswax from the back pot.

Then she took a small bamboo tube and put it on the small porcelain bottle. She scooped a spoonful of beeswax that had already melted completely and poured it into the bamboo tube, submerging the bottle mouth and the wooden cork inside the bamboo tube.

Chu Shiyu quickly understood the key point and picked up other small bamboo tubes and started working.

All the bottles were sealed and the small bamboo tubes used as molds were removed, and this batch of disinfectant was finally ready!

When they hurried to the dining hall, Liu Rusi was suddenly overwhelmed with guilt.

The delicacies on the table were no longer hot, but they were neatly arranged and had not been touched at all. Xue Fei and Cai Yun were waiting, and little Qin Hao was even more so... He was curled up in a chair, holding a book in his little hands, reading leisurely in the candlelight beside him.

However, when Xiao Qinhao noticed her coming in, his first move was to quickly hide the book behind his buttocks...

Liu Rusi was at a loss whether to laugh or cry. She stepped forward and touched his little head, ignoring the fact that he was reading, and said gently, "Haohao, why don't you eat first? You should remember which dishes here don't have peanuts."

"I want to wait for mom to eat together." Little Qin Hao was not asked to read the book, and he was happy and behaved obediently.

Chu Shiyu was stunned and blurted out, "Peanuts?"

"I hate eating things with peanuts. My mother said it might be an allergy, so she told me to try not to eat peanuts." Little Qinhao took the initiative to answer for his adoptive father.

Isn't this just picky eating? Chu Shiyu asked in confusion, "What is an allergy?"

Liu Rusi paused. This was too much trouble to explain. As she sat down at the table, she said briefly, "Some common things are... incompatible with some people. The situations vary. Some people may develop rashes, while others may feel chest tightness... These reactions can be called allergies."

In fact, Xiao Qinhao did not have an obvious allergic reaction. The reason was that on New Year's Eve last year, she and Xiao Qinhao went to her uncle's house for a New Year's Eve dinner. The aunt made a big bowl of peanut pig's trotter soup for Xiao Qinhao, which is a big dish for farmers, and it is also a manifestation of the aunt's love. But Xiao Qinhao, who is usually obedient and sensible, took a sip and refused to drink it.

Since the family had eaten pork and lard before, Liu Rusi guessed that Xiao Qinhao was allergic to peanuts and had anorexia. That night, she drank Xiao Qinhao's bowl of soup herself, and from then on, she tried her best to help Xiao Qinhao avoid eating peanuts.

Other foods can also provide nutrition instead of peanuts, so she doesn't need Xiao Qinhao to use his body to verify whether he is really allergic.

As soon as the two came in, some servants came to replace the hot dishes, and they could enjoy the hot food directly after they sat down.

This extravagant lifestyle made Liu Rusi amazed, but she didn't say much. Most of the dishes that were taken away were what the servants wanted to eat, and they would not be wasted.

Chu Shiyu still didn't understand what allergies were, and was skeptical about it. But he was more concerned about something else, that is, she always tried dishes for Xiao Qinhao because of Xiao Qinhao's so-called peanut allergy?

It was their custom to not talk while eating or sleeping, so it was not until after the meal that Chu Shiyu asked Liu Rusi the question she wanted to know most.

"Then why can't you tell me? If I knew Qin Hao doesn't eat peanuts, I could have arranged for the servants not to cook dishes with peanuts."

"Well... there's no need to make a fuss about it. And we can't ask everyone not to eat peanuts just because Qin Hao doesn't eat them." Liu Rusi explained awkwardly.

In fact, she remembered a scene from a modern movie where the bad guy knew that a person was allergic to nuts, so he mixed nuts into that person's food, and then that person died after accidentally eating a large amount of nuts... So she thought there was no need to tell anyone about the allergy, as long as her family and doctors knew about it.

She had become accustomed to using her keen sense of smell to distinguish food. Moreover, she did not trust Chu Shiyu at the beginning, so she did not think of telling Chu Shiyu, and later she simply forgot about it...

Chu Shiyu was very skeptical about her explanation, but he always kept in mind that she discovered the poison in the soup by her sense of smell, and was glad that she had such a cautious habit.

"If there is anything taboo, you might as well tell me directly. Even if you don't need to interfere, I can have a general idea in my mind." Chu Shiyu looked at her deeply.

Liu Rusi avoided his gaze and nodded slightly.

The busy day quickly ended after dinner, and a new day woke up with a more lively Xingzhou city.

The walking team accompanying Prince Duan arrived at Xingzhou City. In addition to having more manpower for disaster relief work, the courtyard where Liu Rusi and her family lived had two more maids, Meihong and Zhuqing.

This brings up a problem. Yang Xuefei faces the same embarrassment as Caiyun did at the beginning: is she a maid?

Liu Rusi has not yet decided how to treat Yang Xuefei, because some people are completely different people when they are in adversity and difficulties, and she does not yet understand Yang Xuefei's character.

You have to know that the wealth and prosperity that she can enjoy now was actually brought by Chu Shiyu.

Liu Rusi's idea of ​​leaving Chu Shiyu and living independently has not changed. If there is such a day, will Yang Xuefei be blinded by wealth and become an obstacle to her? After all, it is easy to go from frugality to luxury, but it is extremely difficult to go the other way!

"Caiyun, can Xuefei stay in the same room with you? Ask someone to add a small bed for Xuefei." Liu Rusi asked Caiyun first.

Caiyun responded without hesitation: "Okay! I'm just feeling a little scared sleeping alone!"

Liu Rusi smiled warmly. Caiyun was a very optimistic girl. In fact, Liu Rusi had always envied her character. The hardships and poverty of her original family and her current luxurious life had not been able to change her innocence.

"Xue Fei, do you want to move in with Caiyun?" Liu Rusi turned around and asked.

Yang Xuefei observed Caiyun's expression, then looked at Liu Rusi's attitude, then nodded slightly in response.

After Chu Shiyu arranged the marching team and disaster relief matters, he hurried back to the yard and saw that two rooms were being adjusted.

"Why don't you let the maid sleep in your and Qin Hao's room? She can keep an eye on them at night." Chu Shiyu suggested.

"Godfather, I can do it myself. I don't need any care!" Little Qin Hao refused first. He didn't want to live in the same room with anyone except his mother.

Liu Rusi chuckled and said, "I like living alone in a room."

This hobby is not very good, Chu Shiyu thought secretly...
