I am the cook, but I am Li Er's son-in-law

Besides, the success of one's own family is not called success.

The success of the entire market is the real success.

It's just that Huaizhenfang is the only city without a curfew, which is still a bit troublesome. Yin Xuan estimated that if the curfew in Chang'an is over, the passenger flow will at least increase by five or six times.

This is not the amount that a family of Tongfu Restaurant can eat.

Just make as much money as you can.

The shopkeeper happily left, telling the others the good news.

During the daytime of the next day, those who wanted to cook a barbecue would automatically come over with a contract, and asked the scholar to write it in triplicate in lower case, and come over and ask Yin Xuan to sign it.

If Yin Xuan doesn't sign this name, they dare not do this business.

Wait until evening.

Several restaurants have already moved out a stove, set it up at the door of their own restaurant, and lit lanterns, which is already ready for business.

The price is slightly cheaper than Tongfu Restaurant, but the taste and taste are much worse. Many diners who can't wait for Tongfu Restaurant will go to them.

In order to keep these customers, the shopkeepers of those restaurants even sent their buddies to buy beer for three pennies and sell it for three pennies.Not earning a penny.

Not only my own family has fireworks, but also fireworks in the distance.

It’s just that the lantern is an eyesore, it’s drowsy, and there are people hanging big white lanterns in the distance, oh… I misread it, it’s for the vigil of my deceased ancestors.

Huaizhen Square is more and more like a night market.

It's just that there are fewer people.

There are also boys and girls who come out for a tryst in the name of eating, and they are either accompanied by a maid, a book boy, or a father... Oh, that was discovered by the father of the daughter's family, and he was about to give the dog man's leg to him. interrupt.

The human touch is really bad.

Still have to get the lights out.

When Yin Xuan asked this question during the day.

Li Lizhi sighed: "It's done, but... the cost can't be kept down, and some delicate things have to be polished by hand."

As she spoke, she looked at Li Shu.

Li Shu nodded: "I've been calculating the cost. A steam engine costs about 27 guan, and we've been thinking about it for a long time these days, but we haven't thought of how to save some more money."

"The biggest expenditure is on metal smelting and parts processing."

"But the precision is not enough, or the strength of the material is not enough, the whole machine cannot run safely."

Speaking of this, the little girls all writhed.

Yin Xuan watched, and couldn't help but tugged at Li Shu's little face: "Why are you so cute?"

Suddenly, the faces of the little girls turned red instantly.

"This thing doesn't need to save costs." Yin Xuan shook his head, calming down softly, "It's good to make something that can be used, and saving costs is a matter for the future."

"It's not for sale, so the cost doesn't need to be considered."

Whether it can be produced, whether it can be used, and whether it can be developed are two different things.

Yin Xuan will not think about the last question now.

If you can do the second one, it's good enough.

Hearing Yin Xuan's comfort, the little girls felt better.

"Now that I've got this thing out, I'll assign you another task." Yin Xuan tapped the table lightly, and said softly, "Frictional electricity, you all know something about this thing."

"So...the task entrusted to you next is this, how to use the steam engine to generate electricity."

Electricity is the foundation of everything.

Of course, the steam engine can be used for many other things, but relatively speaking, power generation is the most important link.

"Of course, there is also the machine tool, which you need to think about."

machine tool?

The little girls froze for a moment, it was the first time they heard this word from Yin Xuan.

Seeing their blank faces, Yin Xuan explained: "The so-called machine tool is a tool machine. To manufacture a machine, set the precision, and then make parts without manual grinding. Once you put it on the machine, you can Successfully made."

"Businessmen who polish gold, silver and jade should be able to use this thing."

Precision is not a field that only machines can climb. Humans can also touch high precision.

The high-precision parts of the steam engine are calculated by a few young girls, and then handed over to the craftsmen to polish them bit by bit.

But...compared with humans and machines, the efficiency is really much worse.

With machine tools, parts can be processed in batches and batches, and one group after another can be formed in the blink of an eye.The charm of industry lies in this.

The little girls stopped worrying about the cost, and turned to discussing the idea of ​​generating electricity.

Li Shu wrote the thesis by the way.

This is an article to be published in a magazine. The steam engine has already been made. It is difficult to disclose the specific details and drawings, but the principle and some irrelevant data can be disclosed.

A few days later, this month's magazine was published smoothly.

Inside Yongyang Square.

This Fangshi, which is located in the most remote place in Chang'an, is hardly a place where people with self-paying status will set foot, but there are a group of scholars living there.

"The magazine has been published." A scholar came in from outside the house holding a book in his hand, "This issue of the magazine seems to be about steam engines."

"Is it the store's article?" When someone in the room heard it, their eyes lit up.

The scholar who came in shook his head: "No, it's... the articles of those ladies, they have already built the steam engine."

"They made it too?" Some people were surprised and widened their eyes.

The scholar nodded: "Yes."

"How?" Someone asked.

The scholar sighed: "The article did not describe what the steam engine they built looked like, but some principles and calculations coincided with our results."

"It's a pity that it's a step too late." Someone shook his head and sighed, "If I knew it earlier, I shouldn't have made the final adjustments, and I would have shown it to the county magistrate earlier."

"Being one step ahead of those little ladies."

The oldest scholar in the room was silent for a while, then stood up: "It doesn't matter if it's a step late, we still made it."

"But the next thing still needs to be done."

"The details should continue to be perfected, and I will show it to the county boss when it is finished."

Someone muttered in dissatisfaction: "The shopkeeper's wife has already been found out, why should we continue wasting time?"

"So what?" The scholar raised his voice, "Isn't our purpose to make this thing, and then get the appreciation of the county magistrate?"

"Although it's a step late, but as a county birder, you shouldn't look down on us."

Their purpose was never those coins, but to become Yin Xuan's subordinates.

This gave them some courage.

The house was busy again.
