My life skills in Daming Liver

"You Dajian is refining lead?" Su Ze had just entered the silver mine when he saw little Eunuch You staring at a pot of lead water in a daze.

Little Eunuch You turned his head, saw Su Ze, and quickly said, "Mr. Su really offended me. I'm just a handyman in the palace. How can I be called the chief supervisor?"

Dajian is a respectful title for powerful eunuchs, and it is also called "Zhongguiren", which probably means noblemen in the palace.

Su Ze smiled and said, "There is no Xiangguo in this dynasty. Doesn't the chief supervisor also call me Xianggong?"

Little Eunuch You smiled lightly, but felt that Su Ze was getting closer.

Su Ze is different from other scholars and does not discriminate against their father and son.

Little Eunuch You followed Eunuch Hu out of the palace, but he was often scolded by these scholars, eunuchs are nice, and there are ugly things like adultery.

The superficial respect is nothing but fear of the power in the palace, which is completely different from Su Ze's attitude of equal treatment.

Su Ze is a capable scholar, so Eunuch You naturally thinks that Su Ze is extraordinary.

Su Ze continued to be polite without being pretentious, and directly addressed him as Eunuch You: "I don't know what Eunuch You is looking at?"

Eunuch Xiao You said: "Last time, Mr. Su said about the melting point. Gold, silver, copper, iron, and lead can all be melted when heated. There are high and low melting points. Isn't there a quantitative method?"

Eunuch Xiaoyou stared at Su Ze. He also asked his godfather about this question, but Eunuch Hu was also stunned by his question.

Doing chemical experiments naturally also involves temperature, but eunuch Hu's experiments only have vague temperature divisions such as cold, warm and hot, measuring temperature like a ruler? Can this temperature also be measured?

Su Ze looked at Eunuch Xiaoyou's eyes with more appreciation. This father and son are really talented!

Su Ze said, "Of course it's possible."

Eunuch Xiaoyou said happily: "Mr. Su really has a solution?"

Su Ze said: "I told my father-in-law about the technique of investigating things before, did you know about the expansion of heat and the contraction of cold?"

Eunuch Xiao You was really good at observation, he nodded and said: "That's true, when you heat wrought iron, the iron will expand, and when it's cold it will shrink, that's the way of the world."

Su Ze looked up to Eunuch Xiaoyou even more.

Being able to summarize the laws from life is already the basic quality of a scientist. I didn't expect the little eunuch in the palace to notice this phenomenon.

Su Ze simply sat on the ground, and said to eunuch Xiaoyou: "It expands with heat and contracts with cold, you can use this method to determine the value of the temperature, make a thermometer, and measure the temperature like a ruler measures length."

Eunuch Xiao You quickly said, "How to make this thermometer?"

Su Ze said: "Pour oil into a thin tube, take the water to freeze as zero, and take water to boil as a hundred. When it is hot, the oil column rises, and when it is cold, the oil column falls, and a thermometer can be made."

"Wonderful! I'll make it right away!"

Su Ze pulled Eunuch You and said, "Oil doesn't expand much when heated. If you want to make a thermometer, you need a very thin tube."

Eunuch Xiaoyou said: "My godfather has a slender piece of transparent colorless glass, I'll borrow it first, and punch holes in the glass and fill it with oil, is it okay?"

borrow? I'm afraid I'm not going to steal it?

Seeing Eunuch Xiaoyou eager to try, Su Ze also wondered if he could tinker with the thermometer.

Su Ze said again: "Actually, besides oil, there is something better."

"What?"

"Dan Mercury."

Pill mercury is mercury. Emperor Jiajing liked alchemy, and almost all the eunuchs in the palace knew a little bit of alchemy. This dan mercury is really too familiar.

Mercury is liquid at room temperature, but a metal with a much better coefficient of thermal expansion than oil.

Eunuch Xiaoyou said immediately: "I'll go find it right away! I can make mercury with cinnabar, I can do it!"

Su Ze quickly asked: "This mercury gas is poisonous, please be careful when the father-in-law refines it."

"Of course, mercury gas is poisonous, and it takes three turns to make an elixir. Everyone in the palace knows this."

So it turned out that Su Ze remembered that the emperor was not a fool, he had been poisoned to death by taking mercury directly, and what the emperor refined was actually a compound of mercury, other metals, and sulfur.

If he drank mercury directly, Emperor Jiajing would not live to be fifty-nine years old.

Looking at the little father-in-law You who was in a hurry to make a thermometer, Su Ze couldn't help but sigh with emotion. In fact, physics in this era is also a hot land waiting to be developed.

For scientists, this era is simply an era like heaven.

All kinds of results are at your fingertips, not like before the time travel, the PhDs in science and engineering lost all their hair, just to publish some papers in core journals and improve the parameters of a certain material a little bit.

Like the great geographical discovery, this is also an era of great discovery in the field of science.

The more he went into this era, Su Ze did not dare to underestimate the wisdom of the Ming people.

Eunuch Hu has made remarkable achievements in the research of dye technology, and he can even extract salicin from willow bark.

Chinese craftsmen were able to forge the Goujian Sword of the King of Yue during the Spring and Autumn Period and the Warring States Period, such a sharp sword that has not decayed for thousands of years.

But what is most lacking is quantitative analysis.

Metrology, an often overlooked discipline in the development of science and technology, is actually one of the most important disciplines.

Temperature, time, and these abstract things can be quantified into measurable indicators. Only in this way can there be a basis for further research on smelting and materials science.

Take steelmaking as an example, how many degrees Celsius should be quenched to austenitize the steel, and then quickly cooled to what degree can complete the transformation of martensite. The first step in these researches is to know the temperature.

It's not that ancient Chinese craftsmen were incapable of making swords, but these swords were made by accident through experience and coincidence, and there was even a legend about Ganjiang Moxie who was quenched with human sacrifice blood.

Therefore, in Su Ze’s view, Yangming’s philosophy of mind is not a scientific theory at all. Yangming’s philosophy of mind is just a summary of philosophy and methodology, and has nothing to do with modern science.

Scholars in the Qing Dynasty were even more addicted to this kind of "thinking game", and further turned the study of mind into the metaphysics of the Wei and Jin Dynasties, which was further idealistic.

Putting his mind away, Su Ze walked to Eunuch Hu's laboratory.

All I could see was that Eunuch Hu was busy mixing bottles and cans while recording something with charcoal on paper.

Ever since Su Ze proposed the idea of ​​using wine or oil to extract natural substances last time, Eunuch Hu has started experimenting.

Sure enough, oil was used to extract many substances that could not be extracted before, but when extracting with wine, eunuch Hu encountered problems.

If Su Ze was by the side, he would definitely tell Eunuch Hu that it was because the current wine contained too much water and was not pure alcohol, so more substances could not be extracted.

Although eunuch Hu didn't understand the principle of similarity and compatibility, nor what organic and inorganic solutions are, he also guessed that it was because of the water in the wine.

When Su Ze entered the laboratory, Eunuch Hu said in surprise, "Mr. Su!"

Eunuch Hu immediately led Su Ze to a laboratory table, looked at the table full of bottles and jars and said, "Mr. Su, this is the essence of plants and trees extracted from miscellaneous household oil!"

Eunuch Hu was like a child presenting treasures. After showing Su Ze his latest achievements, Eunuch Hu led Su Ze to the experimental platform where he had just written and drawn.

"Su Xianggong, look at this."

Su Ze saw a lot of connected bottles and cans, and he had to say that this Eunuch Hu's hands-on ability was still very strong.

There are no glass test tubes, but eunuch Hu fired ceramic jars himself.

Su Ze also saw a slender porcelain tube connected to a wooden stopper, and the whole experimental platform was full of a Chinese cyber sense.

"Boss Hu, what are you up to?"

Eunuch Hu carefully took out a small bottle, handed it to Su Ze and said, "Mr. Su, look at this."

When Su Ze took it, he smelled a strong smell of wine.

"Dajian Hu still likes to drink?"

Eunuch Hu immediately shook his head and said: "This is not wine, this small bottle is the essence of wine extracted from two cans of wine by the miscellaneous family!"

The essence of wine? Wait, isn't it high-purity alcohol?

Su Ze looked at the complex set of equipment on the test bench again. Isn't this the equipment for condensing and purifying high-concentration alcohol?

High-purity alcohol can not only be used as a fuel for alcohol blowtorch, but also an important chemical solvent.

Su Ze said with admiration: "Dajian Hu is able to extract the essence from wine, he is truly a god!"

Su Ze just explained some basic principles of dissolution and separation to Eunuch Hu, and he was able to come up with this method of heating and condensing to purify alcohol. Su Ze dared not underestimate the wisdom of people in this era.

Eunuch Hu stroked his beardless chin and said:

"The miscellaneous family was also inspired by Su Xianggong's theory of hybridization, and guessed that this wine is also a mixed solution, so they came up with a method to purify the essence of the wine."

After finishing speaking, Eunuch Hu immediately put the cork on the bottle and said: "Mr. Su, the essence of this wine is lively in nature. If the cork is not put on, it will soon dissipate between heaven and earth."

Well, the volatile properties of pure alcohol have been studied.

Eunuch Hu said: "This equipment can not only extract the essence of wine, but also extract the essence of flowers."

Eunuch Hu brought another jar, and after opening it, Su Ze smelled a strong fragrance of flowers.

Eunuch Hu said proudly: "This is the essence of the flower extracted by the same method. Does Mr. Su think the fragrance is strong?"

Isn't this essential oil? When Su Ze looked at Eunuch Hu again, he wished he could hold the old eunuch in his arms and kiss him, but he didn't expect this!

Rose essential oil, this ancient perfume has always been popular in the Middle East, a drop of fine Damask rose essential oil can be sold for the same volume of gold price.

In addition to directly selling essential oils, Su Ze quickly thought of other uses, such as perfume and soap!

Needless to say, perfume can also be mixed with essential oils in the powder.

Nowadays, except for some high-end rouges that are mixed with various medicinal materials and spices, the rouges of ordinary people have no fragrance.

It only needs a little fragrance of essential oils, and it can definitely attract the attention of women in the city. How can any woman refuse all kinds of flower-scented rouges?

Soap, this thing is not complicated to make, but the raw materials are troublesome.

Pigs, the main raw material of soap is the saponification reaction of pig fat and lye. The lye can be obtained by reacting plant ash with caustic soda. Eunuch Hu's laboratory can definitely make it.

But a large amount of pig fat is not easy to deal with. These days, people don’t have any fat in their stomachs. In the era of scarcity, fat meat is more expensive than lean meat. It is too extravagant to use it to make soap.

Let's start with rouge first. From the six vacant shops, you can choose one with a good location and open a makeup shop.

Whether it is high-end essential oil perfume or fragrant rouge, this is a big killer for women, and they can make money anywhere.

Su Ze was very satisfied with the results of Eunuch Hu's laboratory, and quickly said, "Supervisor Hu, can you make a larger device to extract these essences?"

Eunuch Hu thought for a while and said: "If it is mass-produced, it can be simplified."

"You can use a hollow bamboo tube as a conduit, and an iron pot instead of a copper pot, but it's not as pure as the one I made here."

Su Ze was even more pleasantly surprised. Eunuch Hu is an all-around player who is a master of industry, education and research, and he came up with an industrialized solution so quickly.

However, scientists these days seem to be both engineers, such as Galileo Newton, who cursed hundreds of millions of students in physics textbooks. They are not only theoretical physicists, but also experimental physics and top engineers.

This eunuch Hu seems to have both such qualities, with strong hands-on ability and practical ability, even the little Eunuch You who is obsessed with making swords.

Su Ze sighed once again that there is really no shortage of talents in this land of China.

It's just that under the only imperial examination system, many talents are buried in history books.

These people must not be buried again!

Su Ze secretly thought that a history book should not only record these emperors and generals, but also record the names of those who promoted the development of the times and brought innovations to the world.

Su Ze left some money to Eunuch Hu as research funds, and signed a contract with him again, agreeing on the dividends of the other party's technology shares.

Su Ze sat down in the laboratory again and wrote some simple acid-base reactions with a reed pen.

[Discover the location 'laboratory', discover skill chemistry. 】

[Assess the chemical skill level as Lv3]

[Discovery skill chemical industry, merged with chemical skill. 】

[Skill 'Chemistry', Lv3, 27/300]

Chemical skills merged into chemistry skills?

Still rated Lv3 according to the chemical level before time travel?

Su Ze quickly opened the panel, and sure enough, the chemical skills were replaced by chemical skills.

Su Ze picked up the pen again, wrote those vague reactions in more detail, and then handed it to Eunuch Hu and said:

"Superintendent, you can do these experiments. This is what my father once said, and I have never done it."

Eunuch Hu is like a treasure.

Su Ze added: "In some experiments, Supervisor Hu must pay attention to safety, such as this experiment of making acid, you must be careful."

Eunuch Hu nodded again and again, Su Ze didn't dare to write to him those experiments that might be explosive or poisonous, but just selected some simple experiments for Eunuch Hu to try.

It's hard to get this treasure, but it must not be lost in an experimental accident.

With chemistry skills at Lv3, Su Ze is also planning to build a gunpowder laboratory next to Changningwei to research and improve the current gunpowder.

After bidding farewell to Eunuch Hu, Su Ze continued to go to Changning Guard.

Going east along the Jianxi River, not far from the silver mine, Su Ze saw a huge wooden water wheel. He saw a familiar figure beside the water wheel. It was Lin Xianzong, the shipyard master of Changningwei.
