After the prosperous Tang Dynasty

As A Xiu lit the fire under the casserole, Xiao Yansui's eyes became brighter and brighter.

The chemical composition of alcohol is actually ethanol. The boiling point is generally 78.4 degrees Celsius, while the boiling point of water is 100 degrees Celsius. The basic principle of distillation is nothing more than using the difference in boiling point of ethanol and water to try to control the temperature around 78.4 degrees Celsius, causing a large amount of ethanol to be distilled. Volatilizes into a gas, then liquefies when it meets cold at the condenser, and recondenses into a liquid that drops into the collection bottle.

Of course, it is inevitable in this process that some water vapor will still be distilled out, but the alcohol concentration can still be effectively increased.

Xiao Yansui doesn't have a thermometer at hand now, so naturally she can't ensure that the distillate is always around 78.4 degrees Celsius. However, fortunately, she has previous experience in the laboratory. The temperature of the liquid should not deviate too much.

What's more, it's okay if the temperature is a little lower. At most, the distillation speed is slower. She doesn't have any other experimental equipment now, which means she has the most abundant time.

——Speaking of it, the principle of the thermometer is actually quite simple, as long as there is a very thin glass tube, and then fill it with about one-third of colored kerosene, and then seal the glass tube.Put the glass tube in boiling water, the scale where the kerosene is marked is 100 degrees Celsius, and then put the glass tube in the ice-water mixture, the scale where the kerosene is marked is 0 degrees Celsius, and the scale between 0 and 100 is evenly divided.

However, the difficulty of making thermometers lies in the fact that the glass products of the Tang Dynasty were actually glazed glass, which was quite different from the bright and transparent glass of later generations in terms of composition and craftsmanship.Even though Xiao Yansui had several precious glass ornaments in his dowry, it was not easy to get the extremely thin glass tube itself.

Quickly retracting her wandering thoughts, Xiao Yansui reminded: "Axiu, please be careful, don't let the water in the casserole boil."

Xiao Yansui sat on a low stool, her hands wrapped in white steamed buns neatly placed on her knees, and she stared at the entire copycat alcohol distillation device without blinking, with an extremely serious and focused expression.

"Yes, maidservant made it down." Axiu and the other two nodded.

The entire distillation process is actually a rather monotonous waiting process. Except for the initial preparation stage, the rest is just maintaining the water temperature for a long time, and then collecting the liquid dripping from the condenser.However, for Xiao Yansui who really likes all kinds of experiments, this waiting process is full of the charm of technology and science she is passionate about, simple but never boring.

The only small problem is probably that the product distilled from shochu will actually still be wine, not alcohol.

However, Xiao Yansui was only preparing some alcohol for wound disinfection, not for a very delicate experiment. This small flaw is completely within the acceptable range.

About an hour later, there was only less than half of the shochu in the teapot, and there was already more than half a cup of distilled products in the collection bottles connected to the mouth of the flask.

Seeing that the ice cubes on the plate also melted into a puddle of water, Xiao Yansui took the distilled alcohol, moved a little closer to himself, and then gently fanned the mouth of the bottle with his hand, causing a very small amount of gas to float over, smelling After smelling the smell, he thought it was okay, and said with satisfaction, "Let's do this first! Put away all the things after the water is cold, and I can make more tomorrow."

Although Axiu was puzzled, she still complied softly.

Because alcohol is extremely volatile, and the windows were open in the house, after such a distillation, almost the entire courtyard of Xiao Yansui was filled with a strong aroma of alcohol.

Xiao Yansui put aside the bottle of high-strength shochu or impurity-containing alcohol that he just got, took wax pellets and melted it, and after sealing the bottle with wax, carefully placed it on the museum shelf.

Already got the alcohol she wanted, Xiao Yansui went to the yard and sat on the swing in the small garden, her eyes drooping slightly, she looked quiet and well-behaved, she swayed her feet twice, and couldn't help but He began to think about things over at Ximing Temple.

According to her own thoughts, the meditation room where she took a nap yesterday must be the most important thing to investigate, but she doesn't know what happened to her grandfather Xiao Song and Xuanzong at the Xingqing Palace, and what is the matter with her? No chance to go back and investigate...

·

But at the Xingqing Palace where Xuanzong lived, Xu Guogong Xiao Song cried out in public about what happened to his granddaughter in Ximing Temple, even Xuanzong was furious immediately, and immediately ordered Gao Lishi to investigate the matter thoroughly.

After Gao Lishi took the order, the expression on Xiao Song's face finally looked a little better, so he asked Xuanzong for an order to let Xiao Heng, the grandson of the Xiao family who was in Ximing Temple that day, also go to Ximing Temple to investigate the matter.

Xiao Yansui who met the villain, Zhang Dai who happened to help, the three Donggong people who showed up before, and Li Linfu who was hiding in the dark and the people behind the scenes. There was a surge of undercurrents, Prince Li Heng was full of worries, and his expression was even more restless.

When the matter got to this point, some people felt lingering fears, while others knew it well—since Xiao Song was going to reveal this matter in public, and the target was directed at Ximing Temple, it meant that this matter would not end for a day, and Xu Guogong Xiao Song refused to give up for a day...

After the court meeting, Xiao Song turned around and was about to leave, but before he could walk two steps away, his in-law Pei Yaoqing grabbed his sleeve.

Pei Yaoqing is the father of the Pei family, he is a minister in the same court as Xiao Song, and he is usually calm and slow-moving, but it is rare to see him like this.

Pei Yaoqing grabbed Xiao Song and asked: "You just said that my granddaughter was kidnapped by gangsters and was injured? Is the injury serious? I will go with your carriage later, I have to go and see her."

As he said that, Pei Yaoqing couldn't help repeating Xiao Song's words, "What happened in Ximing Temple yesterday? Why didn't you send someone over to give me a word, and directly made trouble at the court meeting, scaring me a lot Jumping, for no reason makes people worry. Oh, my good granddaughter is okay..."

Xiao Song tried to break free twice, but Pei Yaoqing held on tightly, so he couldn't break free.

Xiao Song curled his lips, grabbed his beautiful beard with the other hand, and said impatiently: "Let's go, Liu Niang is at home, you go directly to Xiao's house with me."

After leaving the Xingqing Palace, Pei Yaoqing recruited servants from home to send letters home first, and followed Xiao Song directly into the Xiao family's carriage to visit his daughter and granddaughter.

The actions of Xiao Song and Pei Yaoqing naturally caught everyone's attention.It's just that the two of them were in-laws, and it was Xiao Yansui who had the accident. Pei Yaoqing was worried about his daughter and granddaughter, and no one could find a reason.

On the other hand, Prince Li Heng, who had been besieged by Concubine Wu Hui and Li Linfu all this time, couldn't help but move slightly when he saw this.Whether it is Xiao Song or Pei Yaoqing, they are all important ministers in the court, and they do not favor him, but they have never favored the longevity king Li Mao.The three of Li Chu happened to be in Ximing Temple yesterday, if they can take this opportunity to form a good relationship with the Xiao family...

Thinking of this, Prince Li Heng hurried back to the East Palace, and directly ordered people to find Li Chu, Li Tan and Li Wenning.

Li Heng stood with his hands behind his back, looked at his eldest son, third son and third daughter, and found that the three of them were still as normal as anyone else, probably not knowing about Xiao Yansui, so he was naturally a little disappointed for a while, thinking of what happened in the court today The dark tide was raging, and I felt a splitting headache.

"The three of you, did you go to Ximing Temple yesterday?" Prince Li Heng was a little irritable, frowned slightly unconsciously, and asked knowingly.

If the three of Li Chu could provide some clues, they would naturally be able to sell it to the Xiao family. However, if the two parties had no intersection, the three of them appeared in Ximing Temple at the same time. I am afraid that when Gao Lishi investigated, even the East Palace will be involved...

Seeing his father's uneasy expression, Li Chu's heart skipped a beat, but his face didn't show at all. His words were full of respect and admiration, and he lowered his head and replied, "Yesterday I took my third younger brother and third sister to Ximing Temple for an outing. At noon, When I was about to leave from Ximing Temple after eating vegetarian food, my aunt Xinchang Princess and her party happened. My aunt hadn’t eaten yet, so I didn’t want to disturb her. After saying hello to my aunt, my third brother and sister and I left alone.”

Hearing what Li Chu said, Prince Li Heng's eyebrows finally relaxed a little bit, but he couldn't help but feel a little disappointed, thinking to himself, I'm afraid this time he missed someone who could sell favors to Xiao Song Chance.

After a pause, Prince Li Heng simply told what happened in the court today in detail.

"Xiao Liuniang was injured? When we saw her, she was fine!" Li Wenning blurted out.

However, before the words finished, Li Heng glanced at her, and Li Wenning covered his mouth on his own initiative.

"The sage has ordered Gao Lishi to cooperate with the Xiao family to thoroughly investigate this matter." Li Heng frowned slightly and said, "If the three of you noticed something that day, you might as well say it."

Although Xiao Song had never touched the matter of setting up a reserve, it was well known that he was deeply favored by Xuanzong.

Xuanzong's attitude is ambiguous, Prince Li Heng has always walked on thin ice, naturally he did not dare to make friends with important court officials like Xiao Song, but this time, the sixth mother of the Xiao family almost had an accident, Xiao Song was furious, and he must seek justice for his granddaughter came back.

In this way, it is said that Li Chu, Li Tan and others have indeed seen some clues, so "follow what they like", no matter whether it is useful or not, at least, Xu Guogong Xiao Song will always remember the prince's wish yes……

Moreover, Gao Lishi was ordered to investigate the matter first, and Li Chu and others from the East Palace provided clues, which could also get Xuanzong's eyes.Worst of all, at least Li Linfu's family would never dare to make a fuss about this kind of thing in private, and then refer to his book to make friends with important officials in the court...

Prince Li Heng's hands were hidden in his sleeves, and he clenched his fists unconsciously.
