The next day was a beautiful day, the wind was light, and the best time of the year began.

Tian Zhiyu walked on the way to the greenhouse, walked to the edge of his experimental field, and couldn't help but look at those seedlings carefully, compared with the surroundings, it seems that they are indeed stronger.

Tian Zhiyu didn't know if it was an illusion.

At this time, Lao Chen and Lao Li had already inspected the experimental field, and saw Tian Zhiyu lying on the ground, so he hurriedly walked over, and Lao Chen said: "Tian Gongzi, Lao Li and I go around every day, and pull out the weeds when we see them, so as to ensure that there are absolutely no fish that slip through the net in this field." ”

Tian Zhiyu looked at it, and sure enough, the experimental fields were full of wheat seedlings, without a single weed, and there were more or less various weeds in the surrounding fields.

"It's hard work, and when the wheat is harvested, I'll invite you two to drink and give you some reward," Tian Zhiyu said.

The two of them were overjoyed when they heard this, and hurriedly said: "It should be, it should be, the two of us will definitely help Tian Gongzi take care of this land, and there will never be a single grass or worm." ”

Tian Zhiyu was very satisfied, and then said: "There is also that fertilizer, we also need to prepare more, and when the wheat is tasseled, we will use it again, and the amount used is the same as the first time." ”

Lao Chen hurriedly said: "According to the instructions of the son, all the fertilizers are fermented in the vat, and according to the time, it will not delay the use of heading." ”

Tian Zhiyu nodded, leaving the two of them to continue their inspection, and walked towards the greenhouse by himself.

He went into the wooden house to take a look, and the wooden house was useless, and he thought it was a waste, so he asked the housekeeper to prepare some bedding and put it here, and bought a variety of daily necessities in case of emergency.

And the wine bought from Qiantang Village, there are a few jars in the wooden house, and a few jars in the greenhouse, and the experiment will still be in the greenhouse in the future.

He remembered that when he was in high school, the teacher talked about the purification method of low-concentration alcohol, and he still had ideas in his head, but he lacked the equipment for experiments, especially the lack of various glass tubes, which made Tian Zhiyu feel that it was difficult for a clever woman to cook without rice.

It is also unrealistic to make glass, even if you can refine glass, it is not easy to make perfect condenser pipes and the like, and even if you make it, you don't know what year and month it is.

Therefore, Tian Zhiyu still plans to make a set of copper equipment for the time being, make do with it first, and then optimize it after finding a way to make glass.

He took a pen and paper, drew a model of all the equipment, made a list of what he needed, and set out for the city.

He still found the old man He Xingzhi for this set of equipment, and the old man listened to his explanation, looked at the model he drew, and said with a smile: "This is much easier than those needles, the bigger the thing, the less the problem, the finer the test of craftsmanship." Don't worry about the rain, this thing will be made for you in two days. ”

Tian Zhiyu was very happy after hearing this, this time he gave the old man enough silver taels anyway, chatted with him a few more words, and then went to purchase.

Two days later, as soon as Tian Zhiyu got up in the morning, Yu Xiao came to him, but because Liu Ying'er had a lot of homework, she didn't follow this time.

Yu Xiao came to him for the problems encountered during the rehearsal of "The Peony Pavilion".

It turned out that after Yu Xiao went back, she read the script carefully and liked it very much, so she immediately found the shopkeeper and discussed with her to see if she could perform.

The shopkeeper was also very satisfied after reading it, and let Yu Xiao find someone by himself, and the entire Drunken Immortal Building could be picked at will.

So Yu Xiao found a few sisters who had a very good relationship, arranged roles for everyone, and had been rehearsing for two days.

"That's good, maybe it can cause a sensation when the performance is performed," Tian Zhiyu said.

Yu Xiao nodded and said, "The shopkeeper also said that if we can perform well, we should be able to attract a lot of audiences." In addition, she asked me to sing two extra songs, and Miss Chu Chu and I played the guzheng together, and together, we should be able to win. ”

Tian Zhiyu nodded.

"However, the shopkeeper said that it was better to have an ending to this play, and if it could only be performed halfway, I was afraid that the audience below would make a fuss," Yu Xiao finally said today's purpose.

Tian Zhiyu smiled and said: "This play is originally very long, not prepared for one day, and even if I want to write it, it will take several days, and now there are only three days before the Qingming Festival, and there is no time at all." ”

Yu Xiao also knew that it was unrealistic to let Tian Zhiyu finish writing all at once, so he said: "Yu Xiao knows, no matter what, I am still very grateful to my son, and the shopkeeper said that after the ring is over, I want to have a meal in private, like you to express my gratitude." ”

Tian Zhiyu looked up at her and said, "You have already told you my identity as the shopkeeper?"

Yu Xiao was a little embarrassed and said, "Actually, the shopkeeper didn't believe that I wrote the words and songs in front of me." I've been with her for years, and she knows me too well. But I don't want to say, and she doesn't force it. It's just this "Peony Pavilion", after the shopkeeper read it, he said that he had to know your identity no matter what, so Yu Xiao secretly told her about the son. ”

Tian Zhiyu sighed, his heart softened for a while, but he still exposed himself. If it goes on like this, it won't take long, and I'm afraid that I will still be famous in Yuhang City, so it will be inconvenient to go out in the future.

Seeing him sigh, Yu Xiao thought he was angry, and hurriedly explained: "I have already told the shopkeeper, saying that Gongzi you don't like high-profile, and you don't want anyone in Yuhang to know that you can write something, and the shopkeeper has also promised that he will never tell anyone in Yuhangcheng except her." ”

At this point, Tian Zhiyu could only accept it, he thought for a while and said: "I still have a lot of things to do in Yuhang, if I am too famous, I am afraid that there will be a lot of inconvenience, so you shopkeepers will be exempted from inviting me to dinner." ”

Yu Xiao smiled and said: "Childe, you are really too low-key, if the three deans, or any student in the three academies, have such a talent as Childe, I am afraid that it is not known to the world that has been hyped for a long time, only Childe, who has such a talent but would rather be unknown." ”

Tian Zhiyu can't tell her that he is afraid of the tree, after seeing crazy fans in Taiyuan, he just wants to be a swordsman in peace.

Besides, he has already set a goal for himself, and the poems and songs he can remember are only used to pick up girls as much as possible.

The reason why I tried my best to help you like this was just to pity Su Yijin, Tian Zhiyu thought.

When Yu Xiao was about to leave, Tian Zhiyu was also about to go to the old man He Xingzhi to pick up his things, so he sent her back by the way.

When he arrived at the old man and saw the finished equipment, Tian Zhiyu sincerely admired their craftsmanship. Everything they made was a handicraft, and Tian Zhiyu was a little embarrassed to use it for a while.

After returning to the greenhouse with these equipment, Tian Zhiyu couldn't wait to start his experiment.

He first opened a jar of wine, and without appreciating its aroma, he replaced the lid of the jar with a device with a long brass pipe, and then placed an iron basin on a stove, filled it with water, and put the jar of wine into the water.

Next, he attached one end of the long condenser tube to the copper tube, and the whole condenser tube was placed diagonally downward, and a large bowl was placed at the exit of the other end of the condenser tube.

He put dry wood in the stove and lit it, and began to observe the temperature of the water in the large iron basin.

He remembered that the boiling point of ethanol was more than 60 degrees, and the boiling point of water was 100 degrees, as long as the temperature was heated to about 70 degrees, the ethanol would volatilize back and volatilize out of the wine, and after passing through the long condenser tube, the volatile alcohol would condense into a liquid.

However, it is not easy to control the temperature of the water, and there is no thermometer in this world, so you can only rely on your feelings, and after a few minutes, you can reach into the iron basin and feel the temperature of the water with your own body.

When he felt that the water temperature was almost there, he quickly removed some dry firewood to let the fire burn more slowly, Rao was so, the water temperature was still rising rapidly, Tian Zhiyu simply extinguished all the firewood, leaving only the residual temperature for heating.

At this time, the wine in the jar was already very hot, and gas was constantly leaking out of the copper pipe, Tian Zhiyu touched the condenser tube, and the temperature of the condenser tube began to rise.

Slowly, from the other end of the condenser tube, the liquid began to drip out, the aroma of this liquid is stronger than that of the wine in the jar, more fragrant, even if it still contains water, the concentration of alcohol is much higher than the original rice wine.

Tian Zhiyu didn't bother to look at the wine in the big bowl, he was busy taking care of the stove. If the stove is about to go out completely, he quickly adds some firewood, and if he feels that the fire is too strong, he must quickly remove some of it.

After a while, Tian Zhiyu was sweating profusely.

Such hard labor always pays off, and slowly there is more and more wine in the big bowl, Tian Zhiyu ran over and looked at it carefully, although there were still impurities, it smelled like a spirit.

He dipped a little of his finger in his mouth and put it in his mouth, which was really much stronger than rice wine, but according to the estimation of so many liquors that Tian Zhiyu had drunk, the liquor that was distilled for the first time was about forty degrees.

It's already great, Tian Zhiyu comforted himself like this.

When the first jar of wine was almost distilled, he added some water to the large basin and exchanged it for another jar of wine. There was still most of the jar left in the used jar, and he took out a bowl and tasted it, and it still smelled of wine, but it was already very faint.

After distilling five jars in this way, he poured the liquor from the first distillation into an empty jar, and put the jar into the water for the second distillation.

After the condenser tube came out of the liquid again this time, Tian Zhiyu tasted it again, as if he had drunk the high number of Hengshui Lao Baigan, and for the first time there was a hot feeling in his throat.

Although his throat was burning and his stomach was also burning, Tian Zhiyu was very excited and couldn't help cheering.

However, distilled like this, the dozen jars of liquor, in the end, only one jar of highly counted liquor was distilled, Tian Zhiyu calculated the approximate proportion, if you want to extract enough alcohol for your own experiments, the twenty jars of liquor you bought last time are far from enough.

At this moment, Wu Lihan walked in from outside, saw Tian Zhiyu sitting by a pile of jars and pondering, so he stepped forward and said softly: "Zhiyu, what are you doing? It's time for dinner." ”

Tian Zhiyu woke up suddenly, looked outside, and sure enough, it was already dark/

"Have you been in this greenhouse all day? You didn't eat lunch or dinner, and that Feng Sigong sent someone to find you in the afternoon, what are you doing?" asked Wu Lihan.

Tian Zhiyu smiled proudly, took out half a bowl of wine from the last jar with a small bowl, handed it to Wu Lihan, and said, "Brother Wu Lihan, you taste this wine." ”

He saw that after Wu Lihan took it, he was about to drink it all as usual, and immediately called out to him: "Brother Wu Lihan, you drink slowly, this wine is very strong." ”

Wu Lihan looked puzzled, thinking to himself, isn't the wine you bought all ordinary rice wine? How can it be very strong?

But he took a careful sip, and as soon as the wine reached his mouth, he squirted out again.

Tian Zhiyu had long expected this effect, and couldn't help laughing.

Ulhan shook his head and took another sip carefully, this time with experience, he slowly swallowed into his stomach, and suddenly a painful expression appeared on his face.

"Brother Wulihan, how is it, this is strong enough, right?" Tian Zhiyu said proudly.

After a while, Wu Lihan smacked his mouth and said, "Enough, I have drunk the strongest wine in my life, my throat seems to be burning, and my stomach seems to be burning, causing rain, how did you get it?"

Tian Zhiyu showed him the distillation device and said, "It's just this guy, refined little by little." ”

Wu Lihan looked carefully around the distillation device, and after looking at it for a long time, he didn't understand how such a simple thing could refine gentle rice wine into such a strong liquor.

Tian Zhiyu looked at him with a puzzled face, and said: "In fact, the main ingredients in rice wine are water and alcohol, these two things, water becomes water vapor when the temperature is 100 degrees, and alcohol only needs less than 70 degrees to volatilize, so when I heat it, the temperature is controlled at 70 degrees to 80 degrees, so that the alcohol in the wine volatilizes, and the water is still liquid." After purifying it back and forth twice, it became the spirit it is now. ”

Wu Lihan heard it in a fog, but he still stretched out his thumb to Tian Zhiyu and said: "Zhiyu, there is no way you can't think of it, this spirit, I'm afraid that few people in the world can drink a big bowl." ”

"Of course, this big bowl has to be more than a pound, and few people are not drunk after drinking. Tian Zhiyu said.
