Royal Road

When Liang Feng came to Xishan Taoist Temple, Ge Hongzheng was immersed in his wet hands, holding a piece of thin ice. Liang Feng couldn't help but smile when he saw this: "Zhichuan, as it is cold today, be careful of frostbite your fingers."

"If it weren't for the cold, how to grind the ice." Ge Honghun didn't care, "I already know the magnification theory that the monarch said. I just don't know how many times the colorless glass can be magnified?"

"It depends on the ability of the ponderer, the stars and the moon can be seen in the big, and the dust can be seen in the small. As the saying goes, the Taoist is infinite, and the skills can also be close." Liang Feng replied.

Since the last Lucheng offensive and defensive battle, Liang Feng has come to Taoist temples more often. It always takes two days a week to discuss some scientific truths with Ge Hong. The more he contacts, the more Liang Feng finds that the other party has a wide range of interests, and his thinking is extremely keen, and he has a spirit of inquiring about everything.

Just like this ice cube. Originally, Liang Feng casually mentioned how to make fire with ice. If the experimental conditions are not met, of course the experiment cannot be successful. Ge Hong thought of the principle of yangsui making fire. Yangsui is a concave bronze mirror made of metal, as recorded in "Zhou Li". Grinding ice now is just turning a concave mirror into a convex mirror. This contrast between the positive and the negative immediately made Ge Hong interested.

And this extends to the problem of refraction and focusing at the optical level. Seeing the momentum, Liang Feng threw a magnifying glass, an indispensable prop for biology and astronomy. It's just that the technology is not up to the standard, and the colorless glass cannot be burnt for the time being. Ge Hong is not too cold to freeze his hands. He made ice experiment himself, and it didn't take long for him to study the focal length problem.

Liang Feng hasn't been exposed to these things for many years, and there are not many things that can help. He can only guide a few words from the side. However, this is considered unintentional. Even if colorless glass cannot be produced for the time being, crystal can be used as a substitute to grind into lenses. In this way, simple telescopes and microscopes should be possible. It will be of great help to military operations and biomedicine.

Hearing this, Ge Hong shook his flushed fingers, regardless of the ice, and led Liang Feng into the alchemy room. These days, they still try to study chemical agents, mainly for strong acids and bases. These two are important raw materials for industry, and they are essential elements for the development of yellow powder.

Alkali is actually easy to talk about. Ge Hong himself knew a recipe, taking white charcoal ash and di ash into equal parts, and decocting it like cream. Among them, the white charcoal ash is lime, and the ash is plant ash, that is, calcium oxide, sodium carbonate and potassium carbonate are mixed with water to obtain sodium hydroxide and potassium hydroxide. Although it cannot be purified, it is indeed an alkali. As for the pure caustic soda, that is, sodium hydroxide, it is estimated that it must be polished from Glauber's salt and lime water.

But sulfuric acid is difficult to handle. Liang Feng racked his brains before thinking of green vitriol. In the criminal case that he handled, some people used the local method to calcinate green vitriol to obtain sulfuric acid. However, how to calcine, and even where the green alum comes from, is really a problem.

Ge Hong is not very discouraged. For him, the thoughts he heard from Liang Feng are even more fascinating. Just like Liang Feng said the method of reunification, separation and replacement. When one thing intersects with one thing, new things can be created; one thing can separate the other two things; or one thing can be used to refine the other. This idea has the meaning of life two, two life three, three life all things, and it also coincides with the method of alchemy, which is extremely popular with Ge Hong.

Ge Hong took out a red pill from the medicine cauldron, and Ge Hong handed it over: "This is the lead pill that I only practiced the day before. The effect of combining lead and mercury changes from white to yellow and then red. There is also a pill on the tripod, this Is it related to the replacement method you mentioned?"

Unexpectedly, this Master Ge Tian practiced alchemy in addition to studying chemistry. It is this kind of red pill that is terrible. Liang Feng couldn't help but smile: "Hercury is fake gold, mixed with lead. I am afraid that if the bronze or red copper is changed, it will be treated as an alloy. Afterwards, it will be another decomposition, drawing the essence of the air, and then changing the color. This way. To become a pill is no different from swallowing gold, but it is not the way of longevity."

Mercury looks like a liquid, but it is actually a metal. Because of its ability to dissolve metal, it is very popular with alchemists. The legendary method of turning stones into gold is exactly what mercury does in it. Lead, mercury, and cinnabar are the most commonly used things in ancient alchemy, and they are all highly toxic. Liang Feng would eat this kind of stuff because he was too frustrated.

Ge Hong frowned: "Nine-turned Golden Pill is naturally more than lead and mercury. However, your deduction is indeed a bit mysterious. It's just that there are many things that are sexual, and it is difficult to exchange things with others."

"That's why catalysts are needed, conditions are needed, and thousands of refining methods are born." Liang Feng Chemical has forgotten about seven or eight, but still remember some of the most basic common sense. There are always conditions to be achieved in chemical reactions, high temperature and high heat, electricity and pressure , Or catalyst catalyst, can have all kinds of changes. The lofty status of the ancient alchemist is also because of this, it is indeed a bit tricky to turn one thing into another.

Ge Hong ate this set quite a bit, and did not continue to struggle, put on gloves made of fine Gebu, and a thick mask, and began to demonstrate to Liang Feng the experiments he had done these days. Danfang doesn't have any suitable tools now, and mostly uses porcelain as a container. However, in this way, methods such as distillation and condensation are much more difficult. It is also fortunate that Ge Hong is a genuine alchemist, with a lot of native methods, so he can barely do it.

Ge Hong is extremely reticent in nature, and Liang Feng himself has almost lost the basics of chemistry, for fear of misleading the direction of the experiment. The two are so quiet, but they have a tacit understanding. Occasionally, Ge Hong said something confused in the experiment. Liang Feng dug his thoughts to support him, which could also broaden his mind and let Ge Hong give birth to some new ideas.

In this way, Ge Hong did all the experiments on his hands in less than an hour.

After leaving the pill room, the two of them took off their protective equipment, cleaned their hands, and rinsed their mouths. They just sat aside drinking tea and chatting.

With a light sigh, Ge Hong said, "So groping, I always feel that the interlayer gauze mist. If the glassware you said can have a miraculous effect, you should think about its manufacturing method first."

This is what Liang Feng urgently needs. After thinking about it, he said: "It's better to go back to Liang Mansion with your teacher's appointment after a while. The kiln will not be closed this winter. You can try to purify the glass material to see if you can make something more suitable."

Ge Hong hesitated for a moment and asked, "Is it just Assistant Liu who is going back to the house?"

Both Liu Jian and Li Xin now have the title of teaching assistant and teach mathematics in Chongwen Museum. However, Li Xin is basically immersed in trigonometric functions and cannot extricate himself. Most of them are Liu Jian teaching and also serving as a consultant for the workshop. When the students are on vacation in winter, Liu Jian will go to Liang's Mansion to deal with some problems on the spot. You can go back with Ge Hong.

"Only the teacher makes an appointment..." Liang Feng suddenly reacted, "Is it true that Zhichuan is not happy with Zile?"

Li Xin is a baby bump if he doesn't speak, he becomes an irritant when he speaks, and he has offended countless people a long time ago. Liang Feng didn't expect that even Ge Hong could get in touch with this stuff.

Sure enough, Ge Hong's expression was a little uneasy: "Assistant Li and I have some conflicts in astronomy and geography, which is not a major issue.

It is really not an ordinary conflict to be able to provoke him like this. However, Liang Feng consciously didn't ask too much. These two are mainly engaged in mathematics, the other in chemistry, and astronomy and geography can only be regarded as hobbies at best, and entanglement is of little use.

With a gentle smile, Liang Feng persuaded: "Zi Le Lu is straightforward, there is nothing wrong with it, I don't need to take it to heart. It is the water cone that the teacher has appointed for trial production may replace the human blast and raise the furnace temperature. If it succeeds, it is also a thing. event."

The water cone uses water power to hull grains. It began in the Eastern Han Dynasty, and was later improved by Ma Jun and flourished in the Wei and Jin Dynasties. In Luoyang City, it is used to pound rice. Based on this idea, Liang Feng asked Liu Jian to cooperate with Mufang to develop more hydraulic machinery and equipment. The Liang Mansion is still short of manpower. It is certainly more convenient to have hydraulic power than to rely solely on manpower.

As a result, after using the waterwheel for pulp beating and porcelain clay grinding, Liu Jian came up with a hydraulic blast method. This time I went back to cooperate with Mufang's trial production and strive to achieve a breakthrough.

With this, if a blast furnace can be built again, whether it is glass-making or iron-making, it will be of great help.

Hearing Liang Feng's persuasion, Ge Hong nodded slightly and agreed.

After dealing with the Taoist temple, Liang Feng saw that it was still early and went to the library again. This library has just been built, but a corner of the Prefect’s Mansion has been renovated. There are currently only four rooms. One of them is an ordinary reading room with only book cases and pens for people to copy the slips. One is a guest reading room with a warm pavilion for those guests who provide books. There are also two stores where paper books and bamboo slips are stored, and entry and exit needs to be registered. A penthouse is attached to provide hot water. It's basically a simple library.

The official leader of the library is Cui Ji, but there is also a curator named Xu Xian. This son is also quite good. He studied under Jing Zhao Du Yu, specializing in "Spring and Autumn", "Zheng Shi Yi", etc., has extensive knowledge of books, is talented in writing, and is also proficient in laws and punishments. He is extremely talented.

Because of this library, he was willing to serve as an official in the prefect. Based on Liang Feng's points, a set of very effective regulations was formulated. Regardless of whether it is book storage or borrowing and copying, there are express regulations. At present, the library does not allow books to be borrowed, nor does it accept readers who do not copy or donate books. It is quite well managed.

Seeing that the leaders of the Shang Party came to inspect, Xu Xian also showed a flattery, only saluting respectfully: "Is the man here to read the book or check it?"

Liang Feng didn't hate him with his business-and-business attitude. He smiled and said, "Just take a look at it."

Sui Xian nodded, followed Liang Feng's side, and inspected the new library.

In the reading room, six scholars were desperately copying books, and they refused to lift their heads. There is a stove in the room, which is not too warm and will not cause people to freeze. The chimney is also well placed. Although it burns coal, it doesn't smell too much. There are earth dragons in the Nuan Pavilion, which is much warmer than the reading room. Only two people leaned against the window to read. There is a censer, a desk, and a maidservant in the room. Putting up the screen is no different from staying in your own study. The two library rooms have begun to take shape, and the bookshelves have begun to be sorted. Jing, history, mathematics, agriculture, law, and other geography, foreign objects are divided into categories. There are also military books, but they cannot be copied at will. Only those who have contributed to the military books can borrow and read them.

After reading the catalog and carefully checking the borrowing and copying records, Liang Feng nodded with satisfaction: "The curator is really careful in doing things. We still need to pay attention to fire prevention in the library and make more inspections. By the way, these days are cold, I will kill people. Serve hot soup, two meals a day, for the scholars to take."

Those who can copy books here are not rich people. In order to save time, most of them bring their own dry food and eat two bites. Providing hot water is quite intimate, not to mention the hot soup in winter. Sui Xian sighed: "The Lord's thoughts are really thorough, and the next official will make proper arrangements."

"Those who can come here are all devoted to learning. Don't neglect." Liang Feng asked again, "Can there be an increase in copycats recently?"

Xu Xian replied: "The library was first built, and not much has been heard. When the spring of next year, when more people come to take the test, I am afraid that there are not enough books in the library.

Now that the New Year's Eve is approaching and far away, even if I hear the news, I can't go out for a while. When the news spreads next year and the sky picks up again, it will be the time for the library to truly exert its influence. Even if you have to pick someone with outstanding calligraphy, a large number of scholars will come to copy the book. I am afraid that there is not enough space for the small borrowing room.

"If there is not enough space, just open up a few more. The government office will fully cooperate." It is still clear who is heavier and who is lighter than Liangfeng. Then Fang Jing. This museum is the foundation of the preface of the county, and the director of the museum should be cautious."

These words made a warm current rise in Xu Xian's heart. How many years has it been for an official, why has he ever thought about the importance of the preface? Whether it is the Chongwen Hall or the subordinate library, there is an extraordinary atmosphere. Such an official is the only person who can assist!

Deep in his thoughts, he continued to solemnly say: "The officials should do their best."
