Xian Sun of the Ning Mansion of the Red Chamber

Chapter 219 What is Science?

Since the fifth day of the first lunar month, Jia Ying has been busy again.

The tin stove was successfully built, the only drawback was that the chimney was a bit thicker and heavier, but that didn't hurt much.

The craftsmen were poached by Jia Ying from the Ministry of Industry at a high price, during which Jia Zheng contributed a lot.

Even though Jia Zheng doesn't care about the facts, his popularity in the Ministry of Industry is still very good.Of course, this has something to do with his identity as the father of the concubine, plus he himself does not fight or snatch, being a good guy, his contacts in the Ministry of Industry are naturally much wider.

Craftsman households are of humble origin, and craftsmen households in the Ministry of Industry are not only low-status, but also a high-risk occupation. What they fear most is getting involved with royal affairs, and losing their heads if they are not careful.

If it weren't for the craftsmanship, how many craftsmen would want to sharpen their heads and leave the craftsmanship.The ancient occupational bureaucracy was very strict, and there was an essential difference between a craftsman and a farmer.Farmers pay grain and taxes, and craftsmen have endless corvee.The hierarchical social status has long caused this phenomenon.

The phenomenon of fleeing soldiers and craftsmen is not uncommon in Dagan.

Jia Ying remembers that one of the powers and duties of the Army and Horse Division is that there is such a law: "For local military craftsmen, etc., the old regulations stipulate that each piece of furniture should be placed on the wall in front of the door. Dare to harbor fleeing soldiers, fugitive craftsmen, prisoners, thieves, etc., so that they can be prosecuted."

Jia Zheng recommended many lists of craftsmen for Jia Ying. Jia Ying used the authority of the military and horse department to select a few people from the list, and cleared up the relationship, and put these craftsmen under the name of the military and horse department.

Speaking of this, I have to mention that the status of admiral of the Wucheng Army and Horse Division has really brought Jia Ying a lot of convenience.

Unlike Patrol Battalion and Embroidery Guards, the powers and responsibilities are clear and single.

It can be said that the Bingma Division has official contacts with most of the yamen in central Beijing.

For example: "Every Ministry of Punishment is assigned to the procuratorate to carry out investigations, arrests, autopsies, and recovery of stolen goods."

"Where the capital should be in charge, the streets collapsed, the ditches were blocked, and the surrounding areas of the imperial city collapsed. The Water Division Administrative Committee of the Ministry of Industry is in charge of filling and dredging."

"Whoever chooses a concubine, each department of the Ritual System Department of the Ministry of Rites selects a good woman from a good family in the area they are in charge of, and sends it to the king's hall for selection."

"Where you go to the suburban altar and the country where the prince is out of the mansion, get married, set up a ceremony, set up a feast, send palace people, and lead the fire armor to make offerings."

The Ministry of Punishment, the Ministry of Industry, the Ministry of Rites, the Inspectorate, and the royal family are just some of them.

The trouble is that it is a little more troublesome, but the victory lies in the fact that the road is broad, and everything can be combined without violating the law.

Therefore, under the name of the Wucheng Bingma Si Yamen, you can also recruit your own craftsmen.

In Jia Ying's eyes, these craftsmen are the treasures of great work, so he recruited as many as possible, and divided them into categories, including blacksmiths, carpenters, and even craftsmen in charge of the military bureau.

After receiving the news, Jia Ying led a large group of craftsmen to test the results. In fact, with Daqian's current level of craftsmanship, it is still very easy to build a stove. Except for the bulkiness of the stove itself, there are no other problems. No.

The stove is made of pig iron, which can be cast but not forged, and has a high melting point, so it is most suitable for lighting fire.

Jia Ying, who showed a satisfied smile, ordered the craftsmen to make a few more sets.

There are at least three sets in my house, three sets in the East Mansion, one set, two sets, and three sets in the West Mansion. Well, in short, the more these things the better, it doesn’t matter if I don’t need them. It's all the rage.

The only downside is that it takes a little bit of iron.

Fortunately, I can be regarded as the ruling class, and the privileges that should be used are not hypocritical.

As for environmental pollution, energy conservation and emission reduction need not be considered at all.

How big is the population of Dagan? The registered population of the household department is more than 600 million people. There should be many black households and domestic slaves.

Sulfur dioxide and nitrogen monoxide can be purified naturally.

As for thousands of years later, people will become scum, and think about what those people will do.

However, the concepts that should be spread still need to be paved in advance, that is, the productivity is too backward, many things cannot be done, and it is impossible to change it all at once.

How about getting a radiator or something later?

Well, think about it later.

Jia Ying brought a large group of craftsmen into Jia's mansion.

"It's New Year's Eve, what are you bothering about?" The old lady was really tired, this nephew was really not at all reassuring.Compared with the past, Baoyu, her sweetheart, is better, gentle and quiet, making people look happy and don't have to worry about it.

Jia Ying invited the old lady and others to the newly built big flower hall in the backyard, and vacated the Rongqing hall. The female relatives were present, so craftsmen were not allowed to enter.

"My grandson had someone build a stove, which uses charcoal to make a fire for heating. I have already found someone to try it, and the effect is not bad. I want to install one in the old lady's house. You are old, and the winter in the north It's cold, and although the kang and charcoal stove can keep warm, it's not as convenient as the stove." Jia Ying said with a smile.

"Stove? It's the kind of adobe stove used for kilns? How can we install that at home." Jiamu asked doubtfully, whether this grandnephew is confused.

"It's an iron stove, not an adobe stove. Just wait and see, I'll definitely like it. I'll take a look at the front, so that those craftsmen don't install it in the wrong place." Jia Ying asked Yuanyang to exchange for a few maidservants to play with the old lady. To relieve boredom, he went to Rongqing Hall.

The layout of the rooms of the ancients was very particular. Take the Rongqing Hall as an example. Its architecture contains the ancients' philosophical concept of heaven, earth and nature, where light and shade are in harmony, and all directions are proportional.Where to place screens, where to set footrests, where to place porcelain ornaments for decoration, they are all very particular, and one more point is not beautiful.

As expected of the masters of the court, maybe they don’t have such complicated words to describe what interior design is, but this kind of concept is definitely no worse than those designers in Jia Ying’s previous life memory, which makes Jia Ying’s worry change. No way out.

There are five upper rooms in Rongqing Hall, and the space is very large, so the craftsmen installed two sets of stoves here, one in the east and one in the west. Marble screens are used to cover it so as not to affect the beauty of sight, and the chimney communicates with the outside from under the eaves.

The design of the chimney mouth also incorporates the elements of art, because it is not the thin iron tube of the previous life, the craftsmen carved carvings on the chimney mouth, and even welded some small decorations, and there is a round shape hanging under each chimney mouth. The small leak is used to prevent the coal tar from dripping.

Waist-high fences were erected around the stove to prevent people from accidentally approaching and causing burns.

After setting it up, Jia Ying ordered people to fill it with a kindling, and a layer of broken coals floated on it, and it burned. He also specially called the maids in the room to let the craftsmen tell them how to use it.

After all, the use of charcoal is rare. If you don't know how to knock on the door, if you need to re-ignite one day, the room will be filled with smoke.

After a while, heat came from the furnace wall, making the surroundings warm.

Jia Ying ordered someone to fill the newly built big iron wall teapot with water and put it on it, and nodded in satisfaction.

After the craftsmen retreated, Jia Ying ordered someone to invite Jia Mu back.

Jia Mu's Courtyard is the center of the female family members in the inner house. If there is any movement here, it has been heard by everyone early in the morning. When they heard that Jia Ying installed a charcoal stove here, they all rushed over to take a look.

"Old lady, how do you feel?" Jia Ying looked at Jia's mother and asked.

Jia Mu looked around the iron stove, nodded with a smile and said, "Well, it looks like it is indeed much easier to use than the charcoal stove, and it also has less smoke."

Pointing to the iron pot on it, he asked, "Can you still get hot water?"

Jia Ying nodded and said, "If you want to make tea in the future, you don't have to go to the stove to boil water."

After finishing speaking, he said to the servant girls in several rooms: "This stove doesn't need to be burned all day, it only needs to be heated once in the morning and evening. During the day and night, the fire needs to be suppressed to keep the fire alive, but it doesn't need to be fully heated." Combustion. To press the fire, you need to use coal dust to burn soil paste, how to do it, I will leave it to you later.”

The more Jia Mu looked at it, the more she liked it. She is old and afraid of the cold, but this stove is much warmer than a charcoal fire.

He also explained to Jia Ying: "But there are still a few more, and I will install one in each room later."

"Don't worry, old lady, we have prepared one for each room, but there is no extra right now, so we have to wait if we want to install more." Then, he looked at the two wives and asked: "Eldest lady and second wife, if you think it's good , I ordered the craftsmen to install one for both rooms."

Jia Ying didn't dress up Daiyu's room first, the elders and children were in order, if she bypassed the two wives and put them in Daiyu's room first, Daiyu might not agree.

"Ying'er has a heart." Mrs. Wang replied with a smile.

Jia Ying gave instructions to Xi'er who was waiting outside, telling the craftsmen to turn around and go to the courtyard of the second room of the big house first.

Then he turned to Daiyu Tanchun and said: "Not many stoves have been built, and we have to send one set to the palace and Feng's mansion first. After a while, I will install it in your room."

In Jia Ying's words, there was no particular preference for anyone, except for Daiyu Baochai, who were all blood relatives, so you still have to be careful when speaking, but when pretending, it must be Daiyu's house that takes priority.

On the Dongfu side, Jia Ying also brought two sets over there. Although there are only a few people here, Dongfu is their main line, so naturally they can't be left behind.

Jia Zhen is Jia Zhen, You Shi is You Shi, and there is also a nephew of the eldest son, all of which cannot be ignored.

Besides, as Jia Ying's status continued to rise, the quarrel between him and Jia Zhen was long gone.The two brothers seemed to have forgotten that there was such a thing, and they returned to the state of brothers and sisters again.

However, the relationship between him and Jia Zhen was not much better, and he had to beat him up from time to time, so as not to get carried away, which made Jia Zhen feel a lot of resentment.

But on Qing's side, with him in charge, Jia Zhen dared not mess around.

Everyone in Jia's family also noticed that Zhen and Ying would never be in the same room unless necessary, but with Jia Ying present, Jia Zhen became extremely well behaved.

Even Jia's mother said: "I don't care about it, but it's a good thing for my brother to take care of it."

Of course, this is only what Jia Mu can say in front of the crowd, and other things can be discussed in private at most.

Jia Ying didn't care what Jia Zhen thought of him, neither left nor right could pose a threat to him, and he didn't have the courage.

Between people, you don't have to use violence to gain the awe of others.

The nest is horizontal, not the wind that a family should have.

Of course, the difference in status is still extremely important, even touching the root.

Jia Ying didn't stay in the mansion for long, but took people to the palace, and it was going to be fifteen soon.

After the tenth day of the Lunar New Year, the palace gradually became quieter, and Jia De had some spare time to meet Jia Ying.

But Jia Ying still waited for a long time before seeing Jia De.

During the year, during the first month, Jiade would stay in the harem, but outsiders were not allowed to enter.

It was Jia Ying's first visit to the Qianqing Palace. Although the Qianqing Palace was not part of the harem, in a sense, it was already the real "home" of the emperor.The south of Qianqingmen, including the three main halls, belong to the imperial court, and the inside of Qianqingmen after that is the real "home" of the emperor.

After Qianqing Palace, there are Jiaotai Palace and Kunning Palace, known as the Housan Palace.On the east and west sides of the Sangong are the concubines' residences, which is not far from Fengzao Palace. Jia Ying passed by Fengzao Palace when he came here.

"During the first month of the lunar year, what are you doing here instead of staying in the mansion?" Jia De spoke in a very easy-going tone, not like the past monarchs and ministers, but more homely.

After all, the Jia family also wears the hat of relatives of the emperor, and they are relatives of the emperor.

Of course, the emperor had no relatives.

Jia Ying took care of it first, got Jiade's permission, then got up, and replied: "Your Majesty, the stove I mentioned before has been built. After I have tried it in the mansion, I will bring it to Your Majesty as soon as possible. Look, if Your Majesty is satisfied, you might as well install a few sets for the palace, especially for the concubine, as people are getting old and are afraid of the cold, this stove is a good thing to keep out the cold."

That's what happened.

Jia De asked with a straight face: "Is it really easy to use?"

Jia Ying replied: "The old lady in Chen's house is quite satisfied, and I'm going to install one in Feng Gong's house too. After his leg was injured, he was always afraid of the cold."

"Ah."

A smile appeared on Jia De's face, as if he was very satisfied with Jia Ying's words.

The old lady and Feng Hengshi are both his elders.Knowing that filial piety is good, and being filial to your relatives is the only way to be obedient to the king. If it is really heartless and ungrateful, even if it is useful, I am afraid it will be difficult for people to trust.

Furthermore, if a courtier has no weaknesses, he will cause trouble for the emperor.

"It's rare that you have filial piety, and you can still think of the concubine. I'm not mistaken about you. If that's the case, let someone try it in the palace first. If it's good, I'll send someone to the Palace of Compassion and Peace. You are right, the concubine is getting old, I should be filial and filial."

"I brought the craftsmen here, and I'm waiting outside the palace at the moment. Although this stove is good, there are still a few points that need to be paid attention to when using it."

Jia De also had nothing to do, and it was a novelty, but he was interested in it, and he said that he wanted to honor the concubine, so he didn't dare to be careless, and said immediately: "Let's listen to it."

Jia Ying repeated what she had told the maids in the mansion, and Dai Quan ordered someone to write it down.

However, since it is provided to the royal family, it is inevitable to list some more rules to avoid any trouble.

"What's more, after all, this stove is not like a charcoal stove. It has a chimney. If it is connected to the house, it will be awkward. The royal majesty should not be taken lightly. Therefore, this stove is not suitable for placement in the main hall, because it will hinder the beauty. .It is suitable to place one in the side hall, or the wing bedroom hall."

"Also pay attention to ventilation, so that the smoke does not harm people. The chimney must be checked regularly to ensure that it cannot be blocked. It is also necessary to clean the smoke and rust inside, once a year."

"Finally, it is necessary to guard against water leaks and fires. It is best to have a bucket of water by the side."

There is nothing else besides, and Jiade can understand it, except for the sentence "smoke is bad", which attracted Jiade's special attention.

"Smoke villain?"

Among Jia Ying's many words, this is the most important thing.

"Your Majesty, whether it is charcoal or coal, smoke will be produced. There may be slight differences in itself, but it is generally due to insufficient combustion. There is a way to go too far. Everything must be moderate, and Yin and Yang are in harmony. The way to longevity."

"Incomplete combustion?"

Jia Ying is thinking about how to explain this term to Jiade, as there are no two concepts of chemistry and physics.

But what should be said must be said.

It's one thing to hear or not understand, but another to speak or not.

"Uh, this involves two categories in a new branch of science, one is called physics and the other is called chemistry. Combustion includes physical combustion and chemical combustion. In most cases, it is chemical combustion, such as charcoal and coal. Etc. Physical combustion is relatively rare, as we know, such as kerosene. Under normal circumstances, most of the fuels in the world are difficult to burn fully, so they will produce thick smoke, even dry grass and firewood. Here it is not allowed Not mentioning the three elements of combustion: combustibles, combustion-supporting substances and ignition sources, combustion must meet these three conditions at the same time, the ignition source provides a suitable temperature for combustion, and the combustion-supporting substances are "

"stop!"

Jiade stroked his forehead, and said with a big head.

What did he hear just now?Is it going to be a fire soon?How come there are so many of them?

He also knows the collection of classics and history, and he also knows all kinds of medicine and music, but what is this physics and chemistry?
"Are you here to amuse me?" The emperor was unhappy, and the consequences would be serious.

Jia Ying said seriously: "Your Majesty, what I said is the truth."

Jia De frowned, and said: "Speak directly, I don't have the time to listen to your nagging so much."

"To put it bluntly, everything has its pros and cons, too much. It's like drinking boiled water for fear of scalding, lighting a fire for fear of running out of water, and walking for fear of spraining your feet. You need to pay attention to precautions, but you can't give up eating because of choking."

Now Jiade understood, and after co-authoring and talking for a long time, it was the last sentence.

Jia De had the urge not to continue chatting with Jia Ying.

"You are young, so don't neglect your job. All work is divided among subordinates. Don't put your mind on these things." Jiade could not help admonishing, after all, this courtier is still very satisfactory.

For Jiade's warning, Jia Ying didn't refute and argue that industry is the cornerstone of a country and science is the door to truth.

Empty words are the most exhausting, and the real benefits are in front of you, which is more effective than anything else.

"I would like to follow His Majesty's instruction." Jia Ying replied very politely.

"Well, is there anything else?" Garter asked.

"I also brought some fireworks, which are quite different from the usual ones. It will be the Lantern Festival soon, and it is the time to set off fireworks. I am here to present them to Your Majesty."

"What novelty did you come up with?" Jiade looked at the courtier in front of him, as if he didn't know him a little bit, how could he be so troublesome, look at other officials, it's the first lunar month, wouldn't it be good to drink and listen to music?But I was still curious: "What's the difference?"

"The fireworks made by the minister are more colorful, not like the usual monotony."

The firework technology of the ancients has been very superb. From being used in the entertainment industry in the Sui Dynasty to nearly a thousand years now, the technology has already matured. Many poems have written scenes of fire, trees and silver flowers.

"Dongfeng night blooms thousands of trees and blows down even more, stars like rain."

"One after another is as brilliant as falling stars, and as noisy as fire."

"Spring night in the city is priceless, shining on the bridge of stars, trees and silver flowers."

However, there are more exaggerated elements in the poems. The fireworks in ancient times were not as colorful as people imagined. Most of them were yellow sparks, or simply a little light, and the rest were all smoke and firecrackers. It is the current mainstream.

Although the production process of colorful fireworks is not difficult, the key is that both the color developer and the brightening agent need to be chemically refined, which requires high scientific knowledge.In fact, fireworks belong to Western fireworks, which were introduced from the East to the West and returned to the East after being developed.

There are many good things left by the ancestors, the key is that the descendants are not very good.

Jia Ying only benefited from the convenience of the memory of the two lifetimes, even so, it was difficult for him to realize the colorfulness.

It's just adding two or three colors.

Sodium can be extracted from salt, copper is more common, calcium is not too difficult, lapis lazuli is more common, and it takes a little more effort to get some strontium nitrate with low purity.

There are color developers such as magenta, brick red, verdigris, and sodium white.

However, it is easy to get out magnesium powder and aluminum powder for brightening.

Aluminum powder can be considered, but this kind of ore is rare, and it takes a lot of time to get aluminum ore.

As for magnesium powder, think about it or forget it, the chemical level is limited, especially for long hair, you need to pay more attention to maintenance.

"If you can't see it during the day, Your Majesty can have someone try it out at night, but not many are made, and the rest should be saved until the night of Shangyuan."

After hearing this, Jiade just gave a simple "hmm", seemed not very interested, and even frowned slightly.

Got it on a horseshoe?
Jia Ying couldn't help but wonder.

In fact, Jia De thought of something else. No matter how you look at it, Jia Ying seems a little out of order. No matter how great his ingenuity is put on these things, it won't work.

"Is it because I haven't given him anything to do recently, is it too free?"

Gard thought so.

"It will be Shangyuan soon. When the time comes, Concubine Yuan visits relatives. As the admiral of the army, don't relax."

It's finally here, and I've mentioned "Shangyuan" so many times in vain.

"Your Majesty, don't worry. Your Majesty's return to the province is an honor for the Jia family to honor the emperor's grace. I must be careful."

Jia De nodded: "It's good to know, don't do all kinds of ignorant tasks, don't let me live up to my expectations of you."

"My minister will always remember His Majesty's instruction."

"It's nothing, just kneel down."

Jia Ying kowtowed first, then straightened up again, a little hesitant.

"If you have anything else to say, say it quickly, hesitating, it's not pleasant at all." Jia De frowned.

Jia Ying put on an appearance of listening to the teachings, and said with a smile: "Your Majesty, I would like to ask. When will your empress be able to leave the palace and return to Shengrong Mansion."

"What I mean is that I should make preparations in advance and keep the streets quiet so as not to startle Feng Jia."

"Of course, I'd better go back to the old lady at home. Ever since I received the decree, everyone in the mansion has been sleepless. I only hope that this day will come sooner. The family-visiting villa has already been built. I just wait for the empress to come. You understand your majesty's mood."

Jia De also understands, but it is difficult to empathize with him, he is the son of heaven, and he does not suffer from the separation of his children and relatives, he is the only one in the world who can reward others, and no one can reward him.

However, this is normal.

Can courtiers not be flattered by the favor bestowed by the emperor?
"Concubine returns to the province and has its own court etiquette system. When the time comes, it will be handled by its own supervisor and the Ministry of Rites, and the inner court will also issue an order. You don't have to worry about these."

"I understand."

Anything goes as far as it goes, too much is too much.

It's good to mention it to impress the emperor, but if you talk too much, it will arouse disgust.

Furthermore, he is a minister, and Jiade is the king. This is his duty. How can a minister make demands against the king?

The reason for mentioning this sentence is because Jia Yingxiang let Yuan Chun stay in Jia's house for a little longer.

Don't say anything else, just say "You first entered the Daming Palace to receive a banquet and watch the lanterns to ask for an order", just this encounter will waste a lot of time.

Receiving the banquet and looking at the lights, this is the interaction between the emperor and the concubine's family in the harem, and it shows the emperor's favor for the concubine. This link is important but indispensable.

Whether it can be omitted is entirely up to the emperor.

There is also "worshiping Buddha in Baoling Palace". Buddhism is not a state religion, and it is not included in the ritual system of returning to the province.

Mrs. Wang is respectful to the Buddha, but Jia Ying met her a few times in Yuanchun, but she didn't see this.

Maybe it has something to do with the toffee empress.

The same goes for the upper and lower, and the harem is the same.

But it's a bit outrageous to have a meal at this time, and Xu Chu just left the palace.

It is clearly stated in the imperial decree that "Shangyuan Day returns to the province" and not "Shangyuan Night" returns to the province. This difference is still very big.

Not to mention these things, after all, as long as the emperor has an impression in his heart, there is a possibility that Fang Yuanchun will leave the palace a moment earlier.

Of course, it was only possible, after all, the emperor's will was not something that Jia Ying could control.

Yuan Chun is still very important in Jia Ying's plan. No matter what, Yuan Chun can have the same ending as his previous life. Otherwise, wouldn't it be a waste of time?
What Jia Ying wants is to change, even a little detail is very important.

When Jia Ying was leaving, Jiade suddenly stopped Jia Ying again and asked, "What's the name of the subject you're talking about?"

"Back to Your Majesty, it's called science."

"Well, you go down." Jade said calmly.

This reflex arc is a bit long.

After Jia Ying left, Jiade turned to Dai Quan who was at the side and asked, "Brother, have you heard of science?"

The birth of a new discipline means that a great talent descended from heaven, not a saint, but a celebrity, if such a thing really happened, as the emperor, it is impossible for him not to receive any news.

Dai Quan shook his head and said, "Your servant will send someone to investigate."

Jia De shook his head and said: "Forget it, I'm just curious, Concubine Yuan, please pay attention."

"The slave understands."
