Royal Road - Chapter 141

[Chapter 140 City.]

When Liang Feng came to the Xishan Taoist Temple, Ge Hongzheng was full of wet hands, holding a piece of thin ice and looking at it.

Seeing this, Liang Feng couldn’t help but smile bitterly: “Chichuan, it’s cold today, be careful of frostbitten fingers.”

“If it wasn’t for the cold weather, how would you grind ice.” Ge Honghun didn’t care, “I already know the magnification principle that Fu Jun said. I just don’t know how many times the colorless glass can be magnified?”

“It depends on the skill of the connoisseur. The stars and 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 skill can also be approached.” Liang Feng replied.

Since the last attack and defense of Lucheng, Liang Feng came to the Taoist temple more frequently.

It takes two days a week to discuss some scientific truths with Ge Hong.

The more contact, the more Liang Feng found out that the other party has a wide range of interests, and his thinking is extremely sharp, and he has a spirit of inquiring about everything.

Like this ice cube.

At first, Liang Feng casually mentioned the method of making fire with ice.

If the experimental conditions are not met, of course, the experiment cannot be successful.

However, Ge Hong thought of the principle of Yang Sui making fire.

Yang Sui is a concave bronze mirror made of metal, which is recorded in “Zhou Li”.

Now grinding ice is just turning a concave mirror into a convex mirror. This positive and negative contrast immediately aroused Ge Hong’s interest.

And this extends to the problem of refraction and focusing at the optical level.

Liang Feng threw out the magnifying glass, an essential prop in biology and astronomy.

It’s just that the technology is not up to the standard, and the colorless glass cannot be burned for the time being. Ge Hong doesn’t like to freeze his hands. He personally experimented with ice-making.

Liang Feng hadn’t been in contact with these things for many years, so there wasn’t much where he could be of help, so he could only guide him a few words from the side.

However, this is also considered unintentional planting. Even if colorless glass cannot be produced temporarily, you can find crystals as a substitute and grind them into lenses, so that simple telescopes and microscopes should be possible.

It will be of great help to both military operations and biomedicine.

Hearing this, Ge Hong shook his fingers that were red from the cold, regardless of the ice cube, and led Liang Feng into the pill room.

These days, they still try chemical research, mainly for strong acids and bases.

These two are important raw materials for industry, and they are also necessary elements for the development of yellow fire|medicine.

Alkali is actually good to say.

Ge Hong himself knew a recipe, take white charcoal ash and Di ash in equal parts and fry it like a paste.

Among them, white carbon ash is lime, and Digum 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 pure caustic soda, that is, sodium hydroxide, it is estimated that it will be pondered from mirabilite and lime water.

But sulfuric acid is difficult to do.

Liang Feng racked his brains to think of green alum. It turned out that in the criminal case he handled, someone used the local method to calcine green alum to obtain sulfuric acid.

However, how to calcine, and even where the green alum comes from, is really a problem.

Ge Hong was not very discouraged. For him, the thoughts he heard from Liang Feng were even more fascinating.

As Liang Feng said, the method of combining, separating and replacing.

When one thing meets another, new things can be born; one thing can be divided into two other things; or one thing can be used to make another thing.

This idea has the meaning of two in one life, two in three, and three in all things, and it also coincides with the method of alchemy and practice, which is very popular with Ge Hong.

He took out a red elixir from the medicine kettle, and Ge Hong handed it over: “This is the lead elixir that I just practiced the day before yesterday. The effect of combining lead and mercury can change from white to yellow, and then red. Does it have something to do with the replacement method you mentioned?” I

didn’t expect this Ge Tianshi to practice Dan in addition to studying chemistry.

It’s this red pill that is fatal.

Liang Feng couldn’t help laughing bitterly: “Mercury is fake gold, mixed with lead, I’m afraid it will be treated as an alloy if it changes from bronze or red copper. If it changes later, it will be another kind of decomposition, and it will only change its color by drawing on the energy in the air. Cheng Dan is no different from swallowing gold, and it is probably not the way of longevity.”

Mercury looks like a liquid, but it is actually a metal, because of its properties of dissolving metals, it is very popular among alchemists.

The legendary method of turning stone 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 poisonous.

Liang Feng would eat this kind of stuff because he thought he had a long life.

Ge Hong frowned: “Nine Zhuan Jindan is naturally more than lead and mercury. But your deduction method is indeed somewhat mysterious. It’s just that many things have nature, and it is difficult to exchange them with others.”

“That’s why catalysts are needed, conditions are needed, There are thousands of refining methods.” Liang Feng’s chemistry has been forgotten, but he still remembers the most basic common sense. There are always conditions to be achieved in chemical reactions. .

That’s why the ancient alchemist had a lofty status, and it was indeed a bit of a magic trick to turn one thing into another.

Ge Hong enjoyed this set quite a bit, and did not continue to entangle. He put on gloves made of fine Ge cloth, and a thick mask, and began to demonstrate to Liang Feng the experiments he had done these days.

There are no suitable tools for Danfang now, and most of them use porcelain as a container.

This makes things like distillation and condensation much more difficult.

It was also fortunate that Ge Hong was a genuine alchemist with a lot of earth techniques, so he was able to do it reluctantly.

Ge Hong is extremely reticent in nature, and Liang Feng himself has almost lost his chemical foundation, for fear of saying something wrong and misleading the direction of the experiment.

The two of them were so quiet, but they had a tacit understanding.

Occasionally Ge Hong talked about some confusion in the experiment, and Liang Feng devised a few words to support him. He could also broaden his mind and let Ge Hong come up with some new ideas.

After going back and forth like this, in less than an hour, Ge Hong had done all the experiments at hand.

After leaving the pill room, the two took off their protective equipment, washed their hands, rinsed their mouths, and just sat on the side drinking tea and chatting.

With a light sigh, Ge Hong said, “After groping like this, I always feel the layers of gauze mist. If the glassware you mentioned can have a miraculous effect, you should first think about how to make it.”

This is what Liang Feng urgently needs.

After thinking for a while, he said, “It’s better to go back to the Liang Mansion with the teacher’s appointment later. The kiln will not be closed this winter. You can try to purify the glass raw materials and see if you can make something more suitable.”

Ge Hong Instead, he hesitated for a moment and asked, “Is it only Assistant Teacher Liu returning to the manor?”

Liu Jian and Li Xin are now teaching assistants and teach math in the Chongwen Museum.

However, Li Xin is basically immersed in trigonometric functions, unable to extricate himself, mostly Liu Jian teaches, and also serves as a consultant for the craftsman.

When the students are on vacation in winter, Liu Jian will go to Liangfu to deal with some problems on the spot.

It is possible to go back with Ge Hong.

“There is only one teacher…” Liang Feng suddenly reacted, “Isn’t Zhichuan disliked Zi Le?”

Li Xin was a baby bump if he didn’t speak, and he became provocative as soon as he opened his mouth, and he had offended countless people for a long time.

Liang Feng didn’t expect that even Ge Hong could get involved with this guy.

Sure enough, Ge Hong looked a little worried: “Assistant Li and I have some conflicts in astronomy and geography, but it’s not a big deal.” To

provoke him like this, I’m afraid it really isn’t an ordinary conflict.

However, Liang Feng consciously didn’t ask too much. One of the two is mathematics, the other is chemistry, and astronomy and geography can only be regarded as hobbies at most, and entanglement is of little use.

With a gentle smile, Liang Feng persuaded: “Zile Luzhi has no bad intentions, and Chichuan doesn’t have to take it to heart. On the contrary, the water cone produced by the teacher may replace the human blower and increase the furnace temperature. If it is successful, it is also a It’s a

big deal.”

Water cones use water power to hustle 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.

According to this idea, Liang Feng asked Liu Jian to cooperate with Mufang to develop more hydraulic machinery equipment.

The Liang Mansion is still short of manpower. Of course, it is 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 method of hydraulic blasting.

Going back this time is to cooperate with Mufang’s trial production and strive for a breakthrough.

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

Hearing Liang Feng’s persuasion, Ge Hong also nodded slightly and responded.

After dealing with the Taoist stall, Liang Feng saw that it was still early and went to the library again.

This library has just been built, but it has renovated a corner of the prefect’s mansion. Currently, there are only four rooms.

One of them is an ordinary borrowing room, which only has books and inks for people to copy and write.

One is the VIP lending room, with a warm pavilion for those VIP guests who provide books.

There are also two rooms for storing paper books and bamboo slips, and registration is required for entry and exit.

A penthouse is attached to provide hot water.

Basically a simple library.

The official leader of the library is Cui Ji, but there is also a director named Xu Xian.

This son is also quite good. He studied under the tutelage of Jingzhao Du Yu, specializing in “Spring and Autumn”, “Zheng Shiyi”, etc., and has a wide range of books.

Because of this library, he was willing to serve as an official in the prefectural mansion.

According to Liang Feng’s suggestion, a set of very effective regulations was formulated.

Whether books are stored or borrowed and transcribed, 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, which is quite manageable.

Seeing that the top leaders of the Shang Party came to inspect, Xu Xian also showed a flattering attitude, but just saluted respectfully: “Do you want to read the book or check it?”

Liang Feng didn’t hate his business-like attitude, and laughed. : “Just take a look at random.”

Xu Xian nodded, followed Liang Feng’s side, and inspected the new library.

In the borrowing room, six scholars were desperately copying books, but they refused to lift their heads.

There is a stove in the room, which is not too warm and does not freeze people.

The chimney is also well placed, although coal is burned, but there is not much odor.

There are earth dragons in the warm pavilion, which is much warmer than the borrowing room. Only two people are leaning against the window to read.

There are incense burners, desks, and servant girls in the room.

Putting up the screen is no different from staying in your own study.

The two library rooms also began to take shape, and the bookshelves began to be classified.

Classics, history, arithmetic, agriculture, law, as well as other geographical records, foreign body records are classified into categories.

There are also military books, but you cannot transcribe them at will. Only those who have contributed the military books can borrow them and read them.

After reading the catalogue and carefully checking the borrowing and transcribing records, Liang Feng nodded with satisfaction: “The director of the extension is really careful. We still need to pay attention to fire prevention in the library and make more inspections. By the way, it is cold these days, and I will order someone to do it. Bring hot soup and two meals a day for scholars to use.”

Those who can come here to copy books are not rich people.

In order to save time, most of them bring their own dry food and eat two bites to finish the job.

It is quite considerate to provide hot water, let alone hot soup in winter.

Xu Xian sighed: “The government’s consideration is really comprehensive, and the lower officials will arrange it properly.”

“Those who can come here are all people who are dedicated to learning, and should not be neglected.” Liang Feng asked again, “Recently, the copywriters , can there be growth?”

Xu Xian replied: “The library was first built, and there is not much news. When more people come to take the test and borrow books in the spring of next year, I am afraid that there will be insufficient desks in the library.

” It’s far away, even if I hear the news, I can’t go out for a while.

When the news spreads next year and the weather warms up again, it will be the time when the library will truly exert its influence.

Even if you want to pick someone with outstanding calligraphy, a large number of scholars will come to copy the calligraphy.

A small borrowing room, I am afraid there is not enough space.

“If there’s not enough space, just open up a few more rooms. The government office will fully cooperate.” Liang Feng can still clearly tell which one is more important and which one is lighter. “There is also a collection of books, and there should be as many edition lists as possible. It should be large and complete. Then Fang Jing. This museum is the foundation of the preface in the county, and the director of the Xu library should be cautious.” These

words made Xu Xian feel a warm current in his heart.

How many years have you been an official, why have you ever thought about the importance of order?

Whether it is the Chongwen Museum or the library under it, there is an extraordinary atmosphere.

Such a Shangguan is the only person who can help!

With a deep bow, Xu Xian said solemnly, “Xiaguan should do his best.”
