Poor family mother and son

For crude oil, this is all Chu Qing knows: fractionating different products.

As for reducing the taste, Chu Qing couldn't do it.

But even if these things are fractionated, they don't seem to be of much use at present. For example, gasoline, Chu Qing currently only distributes it to workers to take back the crude oil for washing clothes.

I have been repeatedly told to use it outdoors and not around open flames.

But these alone can still make Xingfu County become a major tax payer in the near future.

If there is lamp oil, there must be lamps, and if there are lamps, there must be various parts.

Chuqing's glass factory started working overtime to produce glass lampshades.

Qiu Sheng also organized blacksmiths in the county to process iron lamp holders, lamp stands and other products.

Soon, all industries were affected.

Chu Qing even drew a drawing of the kerosene stove and asked it to be processed.

Canvas, wool felt, etc. are soaked with asphalt to make linoleum felt, which is used to cover the roof and become waterproof building materials.

A new, unpopular, and impoverished small county soon became a semi-industrial county integrating crude oil extraction, processing, and sales.

Chu Xinghai was a little unhappy that his adoptive mother would stay in the laboratory and not come out when she had nothing to do, because as soon as her adoptive mother entered the laboratory, she would lose track of time and would not know when to eat unless she was called.

"Father, it's time to eat!" Chu Xinghai shouted for the third time: "It's time to eat, it's time to eat!"

The little guy jumped up and shouted under the window.

Chu Qing leaned out of the window and slipped in directly for him: "Smell it, does it smell bad?"

Although the window was open, Chu Qing's tinkering with the kerosene stove still left a lot of smell in the house, but if he didn't smell the smell after being there for a long time, it would be better to let a child with a sensitive sense of smell judge it.

"It's okay, I can bear it," Chu Xinghai asked: "How much longer will my adoptive mother need? It's time to eat!"

Chu Qing hugged Chu Xinghai and walked out of the laboratory, locked the door, and said, "Let's go to dinner now. Tell your stepmother how you use the kerosene lamp?"

Chu Xinghai: "It's easy to use and bright! And my face is not as dirty as before."

Dirty faces and kerosene lamps, two seemingly unrelated concepts, are actually closely related.

Whether it is a candle or lamp oil, it will produce oily smoke. If you read next to the lamp for a while, your face will be covered with a light layer of carbon black.

If you stick a handkerchief into your nostrils, the handkerchief will be black.

This is one of the reasons why Chu Qing doesn't like to stay in this world.

As long as it gets late, everything will look dark.

For example, if you read a book at night, even if it is a palace with a lot of candles lit, there will inevitably be dark corners everywhere, and it will not be as bright as day.

In Kyoto, perhaps the brightest place indoors at night is the Blue House, because it not only has many lights, but also uses mirrors to reflect light.

In Daxuan, candlelight dinner is not romantic, but the norm.

The fumes from the candles blackened not only the face, but also the furniture and walls. Chu Qing had never seen anyone whose walls were as white as snow.

Kerosene lamps still produce fumes, but the Chu family's kerosene table lamp has a removable umbrella-shaped iron cap above the glass cover, which looks like a pavilion from a distance.

The oil fume will be smoked directly inside the top of the hat, reducing the chance of spreading on the wall.

The transparent glass shade not only does not affect the light, but also provides protection from the wind. The iron cap on the top of the lampshade prevents oil smoke from hitting the face. No wonder Chu Xinghai likes it. "Foster mother, what are you doing in there?" Chu Xinghai asked.

Chu Qing: "My stepmother is working on making a valve to control the flame of the oil lamp."

The mother and son walked towards the dining room as they talked.

Chu Xinghai kept asking questions: "Father, tell me, this kerosene lamp is obviously not very clever, so why did no one except you tinker with it?"

Ouch, this question suddenly brought back Chu Qing's memories.

When Meng Dong first went to school, he heard that printing was one of the four great inventions of the motherland, hundreds of years ahead of the world.

Meng Dao once asked: "Why did printing appear so late?"

Compared with other countries in the world, the printing technology of the motherland is considered to be the earliest, but at that time Meng Dong said:
"When your feet step on the mud, they will leave footprints. Isn't this just engraving?
If your feet are stained with mud and water and you step on clean ground, isn't it printing?

Does such a simple thing still count as an invention? "

At that time, Chu Qing was asked.

Yes, seals have been around for a long time. Why did printing not originate until the Han Dynasty, develop in the Tang Dynasty, and not flourish until the Song Dynasty? ?
After thinking about it, it is probably a matter of supply and demand.

Survival is the biggest problem facing the people. Reading and literacy are things that ordinary people don't think about at all. If there is no demand, naturally no one will study it.

When society developed to a certain level, some people developed the method of engraving and printing, but it was difficult to spread due to inconvenient transportation.

When it finally spread, it was of no great use to the people.

The level of production and the relationship between supply and demand are all inevitable factors that determine the sooner or later the emergence and popularity of an invention.

"You have to fill your stomach before you have the strength to think about things," Chu Qing replied to Chu Xinghai: "Just like your adoptive mother, it was hard to support your elder brother in the past, so how could you bother to study these things?

Besides, if it can’t be turned into money, why do it?
Also, even if it can be turned into money, but we don’t have the strength to protect it ourselves, and if someone takes it away, we won’t get anything. "

Chu Xinghai nodded: "What my foster mother said makes sense. Only when you don't have to worry about food and drink can you have the mind to study things. I heard from my eldest brother that Lu Ban, who invented the saw, was also a rich man?"

Chu Qing: "..."

Adults can never keep up with children’s brain circuits!

Chu Qing: "Your elder brother is right. Lu Ban is a rich man, and his family is a not-so-high-ranking noble. Their family is very well-off..."

"Boss!" Xiangzi ran over: "Master Huang and Master Li are back again!"

Since the last time Li Jin agreed to join Chu Qing's bookstore, he took Huang Zhaoxian back to Beijing. He left not long ago, why did he come back so soon?
Li Jin and Huang Zhaoxian did come back, and they brought an old man with them - Liu Ju, the Minister of Household Affairs.

"Mr. Yong'an, I'm rude to pay you a visit," Liu Ju said as soon as he saw Chu Qing.

"Hello, Mr. Liu. Thank you for your hard work, Mr. Liu. Please be safe, Mr. Liu!" Chu Qing hurriedly stepped forward to receive him: "Why are you here?"

Chu Qing was a little surprised. Even if the emperor agreed to cooperate with him, he wouldn't send someone as old as Liu Ju and with such a high official position to conduct business negotiations, right?
"Master, haven't you eaten yet? Come on, I'll treat you to a good meal," Chu Qing said.

Looking at the tired look on Liu Ju's face, you can tell that he hasn't had a good rest. It's dinner time now, so hurry up and treat him to dinner!
Li Jin and Huang Zhaoxian met Liu Ju on the way back to Beijing. Since both of them had dealt with Chu Qing for some time, Liu Ju simply asked them to return together so that they could talk to him about Chu Qing's temper on the way. .

Chu Qing now has the title of Duke, which is very different from the past, and I heard that even the emperor now dares to complain.

It can only be said that Chu Qing was not a good person before, but now he is not a good person!
Such a person who has experienced strife in the imperial court and retreated from the enemy on the battlefield is now in a high position, defying the heaven and the earth. Is it possible that his character has changed?

Otherwise, why did the emperor, with a helpless expression of constipation, send him, the minister, to come and discuss with Chu Qing in person?
