Blessed Dynasty

How much does oil do?

Just thinking about it, Li Xiaofu can name [-] or [-] kinds at will. No matter in terms of food, packaging, industry or construction, the role of oil cannot be underestimated.

But which of these are applicable to the present era?

Li Xiaofu scratched his head, thought for a long time, probably only a few.

And in this, what Li Xiaofu wants to change first, and what can play the most role, is not other things, but the lighting problem.

That's right, lighting!

Those who have never experienced it will never know how dark the lights are here, and what kind of experience it is to only sleep when it gets dark.

Li Xiaofu didn't feel much difference in the palace, but he felt the real difference when he went outside.

Because the oil lamps at this time are all lit with animal fat!

The visibility of Grease's lights was extremely low, and it was only at this time that Li Xiaofu really knew what a light like a bean was.

Because on the small lamp stand, after ignited with a wick soaked in oil, there is really only a bean-sized light, a small ball, and a trembling flame, which makes people worry about whether it trembles a little. will go out.

It's so weak it's outrageous!

But even this little flame, most people are not very willing to use it, and only ignite it when it is urgently needed.

In such an environment, even the moonlight outside is brighter than the indoor lights. It is no wonder that the ancients had the act of chiseling walls to steal light.

"But why is it so bright in the palace?"

Li Xiaofu was very puzzled, because the lights in the palace were very bright, and he had never been outside, so he only discovered this problem until now.

Xin Zhao couldn't help laughing and said, "Because the oil wicks used in the palace are very thick, and there are several on each lamp stand, so if they are lit together, they will naturally be much brighter."

Li Xiaofu's eyes widened. Is that so?

"It turns out that the reason why the palace is so bright is that more wicks are used!" Li Xiaofu frowned, "Can we make a brighter lamp?"

"A brighter lamp?" Xin Zhao shook his head. "The only brighter lamp is torches. Whether it's turpentine or animal fat torches, they are much brighter than lights."

Li Xiaofu was a little disappointed, but after being disappointed, he became more concerned about making the lamp, and as soon as he returned to the palace, he dragged You Daozi to start researching.

In the absence of electricity, what could be brighter than kerosene lamps and candles?

Of course not!

Both the kerosene needed to make kerosene lamps and the paraffin wax used to make candles can all be extracted from oil, which is why Li Xiaofu wanted to bring oil back no matter what.

The problem of lighting for the common people is here!

Li Xiaofu is particularly motivated when he thinks that he can really see the lights of thousands of houses at night instead of the darkness.

Master You Daozi was naturally a little curious about the black oil that the little apprentice had devoted all his attention to, so he couldn't help but ask, "What is this used for?"

burn?

It's not that You Daozi despises it. Although this burns really well, it is not easy to extinguish at the same time, and it always smells pungent. You Daozi always doubts whether this will be poisonous, so he gave it to Li Xiaofu before the experiment. Use a face towel each with yourself as a cover.

Li Xiaofu happily accepted Master's face scarf, although for the safety of himself and Master, Li Xiaofu had already found Xiao Wuyun to escort him, fearing that some harmful impurities and gases would harm Master, he added a face scarf at this time, Nature is prepared.

While wearing a face scarf, Li Xiaofu replied, "I want to make a kind of lamp oil."

"Lamp oil?" You Daozi became even more curious.

"Yes, the light outside is too dim now. I can't see anything clearly when I go out at night, but the lights inside the palace are very bright. I wonder if I can make a lamp that is bright enough without using many wicks. Get the oil out."

"Use this?" You Daozi looked at the unattractive black oil, although it was indeed oil, but You Daozi really didn't like him.

"Yes, that's it."

You Daozi relaxed his mood. The little apprentice has never failed in what he wanted to do. Although it looks ugly, it might be like what the little apprentice said, is it of great use?

Moreover, the black oil itself can be ignited, so if it is made into lamp oil, it should be taken for granted.

You Daozi thought that the little apprentice was directly using this thing as lamp oil, but he never expected that the little apprentice took out an iron kettle first, poured the black oil into it, and then covered it with a cover with holes ?

And there is another cover on the outside of the cover, so Daozi can't understand it now.

"What is this for?"

"I want to break it down and see."

In fact, in terms of academic name, it should be called fractionation.

The wide use of petroleum naturally has its basis. Just fractionation can fractionate many usable products. Different temperatures correspond to different products. Among them, kerosene is a product fractionated at low temperatures.

If the temperature is higher, paraffin and asphalt will be shunted out.

It's just that the temperature of paraffin and asphalt is difficult to control, and Li Xiaofu doesn't remember the specific temperature of the two, so Li Xiaofu decided to start with kerosene.

Just do what you want, You Daozi watched his obedient apprentice working on this strange container seriously, and stopped his sloppy apprentice from time to time when he was in danger of being injured, but more often, You Daozi In a hands-off situation.

"That's it, maintain this temperature."

For people who practice alchemy all the year round, it is very simple to control the heat, so after reaching the appropriate temperature, Li Xiaofu completely handed over the control of the fire to his master, until every drop of black liquid, Gradually flowing down the edge of the container, Li Xiaofu couldn't help but smile.

"It's done."

You Daozi also curiously sniffed the oil that had just appeared, which was much clearer than before, "Is this lamp oil?"

"Yes!" Li Xiaofu packed the kerosene, "Master, let's try it."

There is no specific kerosene lamp. This test is really just a simple test. Dip the wick with kerosene, blow out the lights in the room, and then light the new wick, and a small group of brilliance bursts out instantly. Compared with the lamps with many wicks added in the palace room, it is not far behind.

"It's really bright!"

You Daozi's eyes lit up instantly, and he looked at the kerosene eagerly. If this kind of kerosene was used instead of the original kerosene, the night would be much richer than it is now.

Li Xiaofu was also very happy, although he was still a little gloomy, but it was a world of difference compared to before, Li Xiaofu had nothing to worry about, it was just...

"It smells a bit big."

Li Xiaofu frowned, because he wanted to experiment with the wick, he didn't let Xiao Wuyun wrap it, so he could smell that bad smell.

"Maybe we can spice it up with something else?"

Many wicks also have the problem of smell, so some other spices, such as rosin, are added when making them, and mixed together, the unpleasant smell can be suppressed.

It's just that what Li Xiaofu was mainly worried about was not the smell, but the exhaust gas from the combustion that brought out the smell, which reminded him of the possible harm to the human body.

These exhaust gases are not completely harmless to the human body, and the particles in them may affect the human body. Li Xiaofu frowned and thought for a while, but he still wanted to make the lampshade of the kerosene lamp.

With the lampshade, these exhaust gases will be discharged from the bottom, and some more harmful particulate matter will adhere to the barrier of the lampshade. At that time, you only need to wipe the lampshade, and you don’t have to worry about getting black nostrils in the morning.

Just the lampshade...preferably glass.

"Master, let's make a glass lampshade and come out."

You Daozi has always been responsive to Li Xiaofu's requests, but it's just a glass lampshade, he is already very familiar with it, and within a long time, he made one. On the other hand, the lamp body that Li Xiaofu ordered the craftsmen to make was also finished. Together, with a wick soaked in kerosene, a kerosene lamp is ready!

"Try it, try it."

Li Xiaofu turned the button on the lampshade, and the wick was exposed, then lit it with a flint, and then turned the wick back, and the kerosene lamp started to work.

This kind of transparent lingering light looks extremely beautiful, and when the warm yellow light shines on the face, even the expression looks extraordinarily soft.

After a whole day of work, not only Li Xiaofu was tired, but You Daozi was also very tired from the stress. Now that the finished product came out, they naturally relaxed.

However, it wasn't until they looked up at this time that they realized that it was already dark outside.

The moonlight quietly climbed up the treetops, and the stars in the sky were dazzling and bright. At this time, they should have carried the palace lanterns, but the two of them looked at the freshly baked kerosene lamps and the strong windshield lampshade, but they chose by coincidence. Kerosene lamps to light the way ahead.

The small kerosene lamp flickered, but the light inside the lampshade was always stable. Li Xiaofu and You Daozi came to the Queen's Palace like this.

Well, at night, it's time for Dad to get off work, so it's okay to look for him here.

And just as Li Xiaofu expected, the emperor Li Wu was indeed with the queen.

Before, he had been worrying so much about the army in the north, and then he was worried about the outbreak of the epidemic in various places. The emperor was very haggard, he lost a lot of weight, okay?

Right now, the North is not to be pacified, there are only some aftermath issues that need to be wrought, and the epidemic situation in various places has been resolved, but after a false alarm, the emperor is naturally in a good mood, and he puts down his worries to see his wife!

Speaking of which, it's been a long time since I've done anything embarrassing with my daughter-in-law. Today's moonlight is so beautiful, it's just right!

The emperor's calculations are good, but there is still a cheating son and a cheating master!

So the emperor was chatting with the queen about the miracles of green clouds and green rain that appeared in various places in the memorial and the miracle of black clouds and black rain that appeared in the north, when he saw a baby appearing in his wife's bedroom.

Well, the emperor took a look, this baby looks so familiar, I really don't want to admit that it's my own.

At this time, he must want to ruin his wonderful nightlife!Especially when this kid went around the Northland, his daughter-in-law might feel sorry for him and planned to sleep with him. The emperor felt very threatened.

You can't let this little fat baby stay, maybe you should inform Xin Zhao quickly and ask him to take this little fat baby back quickly?

But before the emperor could act, he saw his master again.

Well, it seems that this is a group activity, and there is no way to throw the little fat baby out.

The emperor's face was very calm, Li Xiaofu and You Daozi were also very calm, Li Xiaofu who was walking in front put the kerosene lamp in his hand on the table, then he climbed up the chair twice, and poured two cups for his master and himself. A cup of tea, and a quick snack for Master.

Hmm, I haven't eaten well after a busy day, I need to eat more now!

When the queen saw that the little fat baby was eating cold snacks with tea, her heart ached immediately, and while ordering the palace servants to serve some hot snacks, she asked the kitchen to stew some milk so that Saburo could make up for it.

As for Master You Daozi?

Remember that Master likes to eat pigeon eggs?Immediately ordered to make a pigeon and come up.

The emperor looked at his daughter-in-law busy before and after, and felt a little bit stuffed. Daughter-in-law, he didn't eat well before he came, because he was anxious to have a good time with his daughter-in-law, so he just came over after eating something casually No, the daughter-in-law didn't take such good care of him.

Heartbroken, envious of her own baby.

Li Xiaofu and You Daozi have long been used to the ever-changing expression of their father/apprentice, and they are still calm at this time.

Naturally, Li Xiaofu and You Daozi didn't come here just to disturb his good business, just after eating snacks, Li Wu was taken to the Yizheng Hall by his own son and master together.

The queen's bedroom not far away is very beautiful and bright, but the emperor Li Wu can only get farther and farther away from here, what a sad thing this is!

so sad!

Li Xiaofu and You Daozi couldn't help but raise the corners of their mouths, but they put it down when the emperor turned around, well, they didn't smile just now, they really didn't!

When they arrived at the Yizheng Hall, the emperor also began to ask the two why they were looking for him.

How important is it that they dug him out of the queen's bedroom at such a late hour?

"That's it."

Li Xiaofu and You Daozi put the kerosene lamp on the table again.

Li Wu is no stranger to glass, not only the clairvoyance before, but You Daozi has trained a group of craftsmen to specialize in the production of glass. , methods such as blowing and pulling are still not proficient enough.

After all, You Daozi's control over himself is beyond the reach of these craftsmen.

But despite this, there are actually some glass vessels that have been handed down in the palace.

This kind of transparent and colored utensils, which are as bright as gemstones, has captured the hearts of many people from the very beginning, even the queen likes them very much, and many new functions have been developed in daily utensils.

Multicolored lampshades are one of them.

Especially when the light inside is bright enough, the colors reflected through the glass lampshade are so colorful and beautiful that even the emperor couldn't put it down for several days.

So for the glass lamp in front of him, Li Wu didn't feel anything wrong at first.

After all, this glass was handed down from Master, it's just a glass lampshade.

But when he observed the glass lamp carefully, Li Wu felt something was wrong.

Hey, this lamp has very little wick.

How did so few wicks shine so brightly?

And the black grease on this one is different from other wicks...

"Wick?"

Seeing that the emperor could see the problem at a glance, You Daozi couldn't help laughing, "Yes, when Xiaofu went out this time, he found that the lights of the common people were different from the lights in the palace, they were dark and small, so he found a new one. Dip the grease of the wick, and the light of this grease is much better than the previous grease."

"Well, there is a lot of smoke and dust, so you need a glass cover to wipe it from time to time. Otherwise, if you replace it with other sand lampshades or paper lampshades, it will easily turn black and cannot transmit light."

There was a thoughtful expression on Li Wu's face.

In fact, at first glance, this is not a big change, it is just lighting. With the current work and rest of the people, basically after sunset, they can rest in the yard for a while before falling asleep. Will get up and work, basically few people stay up late.

But few doesn't mean none, especially with these lights combining stabilization and luminosity.

Some scholars who stay up late to study hard, some embroiderers who stay up late to embroider, some watchmen who work at night, all of these need more stable and bright lights.

"What material is this made of?"

Li Wu couldn't help asking, if the material is not expensive, it is suitable for the common people to use.

"You have seen the materials of the lampshade and lampstand, they are glass and metal." You Daozi said, "But the most important part of this lamp is not this, but the lamp oil inside."

You Daozi opened the lampshade, and showed the emperor the small tank with kerosene underneath, "This is the main fuel for the lamp, and this lamp doesn't consume much wick. You only need to fill the black oil on time, and it can last for a long time." use."

The emperor's eyes suddenly brightened, "This black oil?"

"Although this is not recorded in the booklet, I have contacted you alone before. When I met the Di Ren Shaman, the Di Ren Shaman also used a new type of weapon, which is this kind of flammable black oil. After being brought back by me and Xiaofu, Xiaofu used that black oil to develop this kind of oil that can burn stably."

"As for the output of that black oil..." You Daozi paused and said, "With my skill, I still can't exhaust all of it."

"In other words, this kind of lamp can be mass-produced?"

"Of course." Li Xiaofu answered while listening to Master and Dad discussing while sitting on a chair in the Yizheng Hall.

If it can't be mass-produced, then what's the use of doing it?

The emperor immediately cheered up, and even the queen didn't think much about it. Now he finally knew that the ministers would rather disturb him in the middle of the night than enter the palace. Pulled out from the bed.

How can such a lamp that benefits the country and the people not vigorously promote it?

Seeing his father's excited look, Li Xiaofu couldn't help but said, "Dad, have you ever thought about how to price this lamp?"

The kerosene lamp used glass and metal, which was naturally worthless in his previous life, but now, glass seems to be very expensive, and metal is a forbidden product, which needs to be reported. Can anyone afford it?

The emperor's feverish mind also cooled down when he thought of this. Looking at the lamp on the table, it looks bright and expensive. How should the price be set so that the common people can afford it?

if low?

Whether it can be paid back is the question.

If high?

People can't afford it.

However, due to the scarcity of glass and the cost of metal, no matter what the price is, a considerable number of people will not be able to afford it.

Li Wu turned his head, saw Li Xiaofu's hesitant expression and said, "If you have an idea, why don't you tell me?"

Li Xiaofu pursed his lower lip, "Daddy, can we provide the lamps to the common people for free?"

"Free?" Li Wu's eyes widened, but he didn't interrupt Li Xiaofu's speech.

"Yes." Li Xiaofu continued after hesitating for a while without hesitation, "Provide lamps to the people for free, but we can sell lamp oil to them by the imperial court. This should be in the hands of the imperial court. After a long time, the cost of lamps and lanterns will definitely be able to rely on the price of lamp oil to earn back, and the common people will not be injured by lamps or insist on not buying them.”

Li Wu pondered, this method is simple to say, but in practice, there will definitely be various difficulties.

Free of course is good, but how can we be sure that these lamps are really in the hands of these people?Will someone impersonate?Will someone sell the lamp again?

This is the problem.

But this idea is good. With the current cost of lamps, people may not be willing to spend money on a lamp, but if we follow Xiaofu's idea, more people will benefit.

"And kerosene lamps can be used for a long, long time. If preserved properly, such a lamp can be used for decades without breaking."

Li Wu's heart suddenly became more inclined to this method.

It's just that they are the only ones discussing this issue now, so there must be some omissions, so Li Wu decided to wait until tomorrow morning to discuss this matter with Lin Xiang and Fang Rufang.

"Then now?" Li Xiaofu looked at his father who had made a decision instantly.

"Now? Of course I'm going to sleep. I'm going to your mother's place."

Li Wu took a few steps quickly, and before Li Xiaofu could catch up, he fled with a kerosene lamp.

Li Xiaofu seriously suspects that his father's passive sabotage is to get rid of him so that he can find his mother so quickly.

Just when Li Xiaofu was blaming his father, he didn't expect that as soon as he went out, he saw Zhao Xiaoxin standing in front of the palace gate.

"Trust brother?"

Li Xiaofu blinked, why is Zhao Xiaoxin here?

Xin Zhao saw the little chubby baby coming out of the palace gate, couldn't help but take two quick steps, stepped forward and picked him up, "The emperor told me to pick you up and go back to sleep."

<(－︿－)>Hmph, he said that his father had a conspiracy, and he even thought of a way to prevent him from going to A Niang.

But thinking about being squeezed together with his father and mother, and thinking about being able to do whatever he wants in Zhao Xiaoxin's bed, Li Xiaofu immediately calmed down.

Well, if you don't go, you don't go.

He slept well with Zhao Xiaoxin too!

So Li Xiaofu, who wanted to understand, was happily taken back to the dormitory by Zhao Xiaoxin, ready to sleep together!

Of course, before that, Zhao Xiaoxin had to rub his belly for him.

Going to bed right after eating is not very good for the body, it needs to be digested and digested~
