When he got up the next day, Xu Ping first looked for Xu Chang and asked him to buy coal, which was mostly called charcoal at this time. When I asked, I found out that there was a boat transporting carbon in the Jinshui River, and in fact, Xujia Restaurant used it for frying wine. I asked someone to bring a letter to the restaurant and asked Liu Xiaoyi to send a car back.

Today is April Gengwu, thirteen, tomorrow is the emperor's birthday Tianchen Festival, remembering that he will continue to read after the festival, Xu Ping has a headache. It's not that he's bored with school, it's that he's not interested in what is taught, and he feels that he can't learn anything he needs from it, which is torture.

After breakfast, Xu Ping took Xu Chang and Gao Daquan around in the field, he wanted to see what crops could be used here, this world is a bit chaotic in terms of plant varieties.

Sure enough, a lot of alfalfa was found, and it was in full bloom, Xu Ping sighed: "This alfalfa is suitable for planting in the village, but unfortunately there are no seeds now." ”

Gao Daquan said: "Why should officials bother about this! This kind of alfalfa used to be collected by the horse supervisor, and it was all to be scattered in the grass, but now many group leaders and shepherds have it in their hands, so they just have to buy it. ”

Xu Pingxi said: "There is still such a thing? ”

"That's nature, this grass horse loves to eat the most, but the cattle and sheep will get sick if they eat too much, and the place where the cattle and sheep division takes over will not be planted. Strange to say, I've also traveled a lot of places, and this kind of alfalfa is only available in this place. There are several other kinds of plants and trees, which are not seen in other places, and even disappear from Zhongmu County. ”

When Xu Ping heard Gao Daquan say this, his heart moved, and he asked him: "What about the peanuts?" ”

Gao Daquan said with a smile: "Falling peanuts are only produced in this place, and there are no other places at all." If I hadn't gone to Chunze to supervise the herding of horses, I would never have imagined that there was such a thing in the world. There is another fruit, which I have not heard of what it is called, which is about the same size and color as persimmons, but it is grassy, and it is not so sweet, but it is also sour and delicious. ”

Xu Chang said on the side: "That's a grass persimmon." ”

Xu Ping glanced at Xu Chang and said in his heart, it turns out that you are called grass persimmons, which are obviously tomatoes or tomatoes, and the place of origin should be revealed. but the heart is settled. These things are only produced here, and they must be connected to the same place as themselves, and it seems that they are really the benefits of their own crossing.

After a while, in addition to the varieties I saw in the vegetable garden that day, I found a piece of sweet sorghum, and I couldn't help but be ecstatic and asked, "Is this also a human seed?" ”

Xu Chang said: "Lu Su? There are people who plant it, but there are very few of them, and they can only be used as children's snacks, and the food produced is not much, and the quality is poor, and the farmers don't like it. ”

Xu Ping stepped forward, looked left and right, and was almost about to look up to the sky and laugh. This is a breed from my previous life, even in that world, this is also a species that opens up, and its adaptability and economic value are unbelievable. The only pity is that the two advantages of this variety are useless to the current Xu Ping. One is that it can produce alcohol efficiently, which is more powerful than sweet potatoes or something, but at this time the wine is monopolized. The other is that this plant produces sugar, and the sugar content of this excellent variety is about to catch up with sugarcane, but Xu Ping does not know the specific process of extracting sugar from it, and it is impossible to study it. The only remaining use is as fodder, but for this purpose it can also be used to kill other crops except alfalfa.

After watching it for a while, Xu Ping kicked down a tree, broke off a piece and chewed it in his mouth, which was really sweet. remembered Xiuxiu, who was bored at home, so she got two more trees and brought them back to satisfy her hunger.

Finally, after the turn, Tamarix and Purple Locust were found, which can be planted in ditches and roadsides, which can not only prevent wind and sand, but also treat salinity.

By the time they returned to the courtyard, it was almost noon, so Xu Ping asked Xu Chang and the two to go to the courtyard separately and went back to the courtyard by themselves.

Xiuxiu sat under the tree doing needlework, and when she saw Xu Ping coming in, she hurriedly saluted.

Xu Ping gave her the sweet sorghum: "Taste it, is it sweet or not?" ”

Xiuxiu smiled: "I used to eat this as a sweet stalk, and it was sweet, but it was too difficult to chew, so I stopped eating it later." ”

Xu Ping looked at her strangely, the little girl in her previous life liked to eat these snacks the most, why didn't Xiuxiu like it? He said to her: "Teeth should be sharpened often, and the more they grind, the better." ”

Xiuxiu lowered her head and smiled: "The official said that I was laughing, and I am not a mouse." ”

Xu Ping shook his head, ignored her anymore, and found a jar of liquor steamed yesterday, and how to increase the alcohol concentration and make an alcohol lamp.

The liquor in the jar is about fifty or sixty degrees, and this is because the retort and the lees in the retort have a condensing effect, and it is possible to obtain a high degree of liquor without a condenser, but it is a little difficult to further increase the alcohol concentration. In the previous life, you don't need to think about any complicated tower distillation, you can only use the soil method.

It is difficult to say whether alcohol is soluble in water or water, which is fundamentally different from low-alcohol liquor, which is also the fundamental reason why traditional Chinese liquor is fifty or sixty degrees high. Once the alcohol content of liquor is reduced, impurities will precipitate out and become cloudy, and the unique aroma will quickly disappear and become undrinkable. As for the clear and transparent low-alcohol liquor in the previous life, it was a product obtained with a special process, and there is no need to think about it in this world.

There are two ways to increase the alcohol content with the local method. One is low-temperature distillation, the constant boiling point of the alcohol solution is about 80 degrees, and distillation at this temperature can get 95 degrees of alcohol, and there is no way to get higher. Another is to add water-absorbing substances, such as lime and anhydrous bilile alum, and the practical value is to add lime.

Xu Ping remembered that seventy or eighty degrees of alcohol had the best burning effect, so he didn't want to bother to distill, so he went out to find a bag of lime and came back.

Pouring the wine into a large bowl, Xu Ping put a large handful of lime into it.

Xiuxiu felt curious, came over and squatted to the side to watch, and asked Xu Ping: "Official, what are you doing?" ”

Xu Ping hadn't done this kind of thing either, and he didn't know the bottom in his heart, so he didn't answer Xiuxiu, just watched.

As soon as lime is added, the liquor becomes cloudy, and then, and then it is still cloudy.

Xu Ping remembered that he still had to filter, but what kind of filter? In this era, the tools are really a bit scarce, and there is nothing handy for a while. Is it just left to clarify slowly? Don't joke like that, alcohol will evaporate.

After thinking for a while, Xu Ping sighed and said to Xiuxiu: "Xiuxiu, let's steam the bar." ”

Xiuxiu smiled: "Didn't the officials let the Zhuang Ke finish steaming outside?" Why do you still want to steam? ”

Xu Ping smiled mysteriously: "This time is a little different. ”

Xiuxiu is also a child, so she followed Xu Ping to find a piece of slices, cut it and put it on the big bowl where the wine was poured, carefully covered it, and smeared it with mud. There was a large empty bowl next to it, still pasted with slices and mud.

Then I found two clay pots and put the bowls in them, and the two bowls were connected with bamboo pipes.

Xu Ping asked Xiuxiu to boil water, and poured cold water into the basin of the empty bowl.

After Xiuxiu boiled the water, she poured it into the basin containing the wine bowl, Xu Ping was afraid that the temperature would be too high, so he hurriedly added a bowl of cold water. I don't know how many degrees it is, as long as it doesn't reach the boiling point of water.

After everything was done, he squatted on the side with Xiuxiu to watch, and felt that the temperature of the hot water had dropped, so he asked Xiuxiu to add water.

After a while, there was a ticking sound coming from the empty bowl. Xu Ping was overjoyed, and found an empty bowl again, and removed the slices of the wine bowl, which contained a small half bowl of wine, emitting a strong smell of wine.

Xu Ping poured some empty bowls in his hand and said to Xiuxiu: "You go to the stove and bring a burning firewood with you." ”

Xiuxiu took the firewood, Xu Ping took it, pulled her back a few steps, the firewood in her hand reached far to the bottom of the bowl, and the wine suddenly ignited, emitting a blue flame.

Xiuxiu was startled and said strangely: "It turns out that this wine will burn!" Is this soju? ”

Xu Ping laughed: "Of course, of course, this is soju!" ”

I was overjoyed, and sure enough, I didn't know how many degrees of alcohol it was. Ignore these complex issues, as long as it can burn.

After waiting for a while, the fire in the bowl was extinguished, and when I looked over, there was not a drop left at the bottom of the bowl, not even water.

Seeing that the alcohol he made was to his liking, Xu Ping and Xiuxiu steamed for a while, and didn't stop until they had made up most of the bowl.

Still covered the half bowl of alcohol with slices and mud, this time without inserting a bamboo pipe, Xu Ping asked Xiuxiu to find a long wick, and used this bowl to make an alcohol lamp.

Lighting the lamp, Xu Ping looked at the sky, the bright sunlight sprinkled all over the sky, and he didn't know how bright the light of this lamp was. I had to wait until the evening to try again, God forbid it should be brighter than an oil lamp, otherwise it would be a bit embarrassing.

To put out the alcohol lamp, Xu Ping found that he had no way to start. It's an alcohol lamp, and it's filled with high-concentration alcohol, and it's amazing to blow sparks into it.

After thinking for a while, I found a bamboo tube, truncated it and put it on the flame, and then extinguished it after a while.

Seeing Xiuxiu's face full of curiosity on the side, Xu Ping said to her: "Xiuxiu, you can remember, this light can only be extinguished in this way, and you must not blow it with your mouth!" ”

Xiu Xiuqi said: "Why? What happens if you blow it? ”

Xu Ping raised his face and scared her: "Don't care why, if you blow it, there will be no Xiuxiu in the world." ”

Xiuxiu looked at Xu Ping, and after a while, she laughed out loud: "The officials saw that I was young, so they used this kind of thing to scare me." I'm not a kid anymore. ”

Xu Ping saw that she didn't believe it, and he was a little impatient, and he didn't let her see it, I was afraid that it would cause trouble in the future.

found a slender bamboo pipe, got through it, pulled Xiuxiu away from the lit alcohol lamp, aimed the bamboo pipe, and Xu Ping puffed up his mouth to blow.

This bamboo pipe is a bit long, and it can't be blown out at once.

Xiuxiu looked at Xu Ping's cheeks bulging high, felt a little funny, and said to him: "Don't coax me, the officials are tired like this." I'll blow it to you. ”

Xu Ping was in a hurry, stood on tiptoe, and the bamboo pipe was aimed at the flame from top to bottom, and blew it over in one breath.

I only heard a "bang", and the alcohol lamp exploded.

Fortunately, the coarse porcelain bowl has a rough skin and thick meat, and it is very strong, but it is only fried into a few large pieces.

Xiuxiu covered her mouth on the side, already frightened.
