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

This can be said to be a very generous treatment.

In addition, Yin Xuan is also famous—not that Yin Xuan is such a famous person. In the eyes of ordinary people who know Yin Xuan, besides the label of "capable", Yin Xuan also has a A very important label is "making money".

From a dilapidated small restaurant with no food to eat, to today's county uncle, a small two-story building, and a wealth of wealth.

Many merchants no longer worship Zhao Gongming.

Set up a memorial tablet of Yin Xuan at home and offer incense to him.

Yin Xuan didn't know about it, but Wang did.

Wang didn't think there was any problem with this at all, and she was even very active in promoting it. Sooner or later, her son would go back to heaven and become a fairy.

Now that everyone worships him as the God of Wealth, will the sky be justifiably the God of Wealth?
In the eyes of those ordinary people, what Yin Xuan does is to make money. Cotton is made by Yin Xuan, so it must be able to make money!

They don't have that big of a resistance—it's not so easy to change rice. After all, after decades of planting, suddenly change, no one will adapt, and there will be confusion about the future.

The imperial court is not so convincing enough to persuade the people.

But money is different.

Things like money are much more reliable than the imperial court. Moving Yin Xuan out is equivalent to making money, and telling them, "Go grow cotton."

"Is the imperial court promoting cotton planting?" Yin Xuan's eyes lit up.

The scholars are very relieved that the store is still the same store. Although they will not go to the court to be an official, they still care about this kind of improvement of people's livelihood.

What Yin Xuan thought about was not what this group of scholars thought.

Planting cotton means...the textile industry will be evolved—Yin Xuan has already prepared the materials needed for the evolution.

The textile machine has long been researched by a few little girls.

Wait until the cotton is mature next year, and then take advantage of the trend to make the loom, and then secretly trick Li Shimin to let go of some trade restrictions.

People will have money in their hands!Being rich is a good thing, which proves that the lower-level market has finally ushered in the opportunity to develop.

Prepare meals for the group at noon.

Yin Xuan wiped his hands, sat among several girls, squinted his eyes, and knocked on the table: "The bicycle is still being improved?"

"Yeah." Li Shu nodded and pulled out a piece of paper, "We found that adding something can make the bike more stable..."

"However, we calculated the results and even drew the blueprints, but we couldn't make them."

"Brother Zhengyang, take a look and see if I did something wrong."

On the paper, there is a two-layer iron ring drawn, inside is a bead, and there are some dense and complicated arithmetic formulas beside it.

Yin Xuan raised his eyebrows, a little surprised, a little surprised.

The thing Li Shu painted is a bearing, even a relatively mature bearing, which is of course difficult to manufacture with Datang's current technology.

The equation next to it shows some shadows of the Reynolds equation—very shallow shadows, and there is still a long way to go before it can be fully deduced.

But after all, it was a little sign that Li Shu figured out by herself.

If this is left to future generations, it will be no problem to win a gold medal in the International Olympiad.

"Amazing!" Yin Xuan rubbed Li Shu's head, "I can think of these things."

Li Shu tilted her head: "Brother Zhengyang already thought of it?"

"Well, it's a matter of craftsmanship if you can't make it, and your direction is right." Yin Xuan put down the paper in his hand, with a bright smile on his face, "This is a very, very powerful discovery."

"I won't teach you, I hope you can deduce this thing yourself."

As he spoke, he stretched out his hand, clicked on the line of mathematical formulas, and couldn't help pinching Li Shu's face.

The three little girls had some tastes.

It's not that they are jealous, it's just that they have a strange feeling in their hearts. They have never seen Yin Xuan praise someone so excitedly after getting along for so long.

Even for the things they made before, Yin Xuan praised them lightly.

The current compliment is too hot and strong, and it's all for Li Shu alone!
snort!
Isn't it just a formula?

The three little girls put their heads together, looked carefully again, and decided to use their sharp eyes to see what kind of charm these few lines of calculations have.

Yin Xuan patted Li Shu's head again: "Put this thing aside for now, this is not a problem that you can solve in one to two years, two to three years, or even five to six years."

"Next, I'm going to teach you a fun thing."

Li Shu tilted her head, she thought that brother Zhengyang praised her so much, and she would be able to get the result of this calculation in a short time, but... the result will take so long?
She hadn't had time to continue thinking.

Yin Xuan took the pen and paper and started to draw. After a while, a strange thing appeared on the paper.An airtight pot, like a roast sheep, with a small ball with a braid on it.

food?

It was hard for the little girls not to think of this.

"This thing is called a steam ball, and it's a very interesting gadget." Yin Xuan drew the parts needed to make it and how to assemble it. "After you go back, you can have someone build it."

"Just be careful, this thing might explode."

Yin Xuan paused, then continued: "After you get it out, you can think about why this thing reacts like that."

"Think carefully and come up with a result."

"When you get the results, I will teach you other more interesting things."

The little girls nodded, and after Yin Xuan finished the painting, after a few glances, Li Lizhi sent someone to send the thing back to the palace, and when they returned to the palace at night, the thing was already done.

There is not much requirement for precision, as long as the sealing is good enough.

Fill the lower pot with water, tighten the lid, and place the balls.The fire was raised, but this strange machine remained silent for a while.

The little girls were not in a hurry, and waited patiently for the water to boil. After a while, there was a whistling sound, and a puff of white gas was emitted from one of the ball's braids, and the ball was pushed, and the other braid , the white gas spewed out a step slower.

The ball started to spin slowly, faster and faster, faster and faster...

"Wow, this thing is going to explode." Li Lizhi stepped back a few steps, shrank her head, and hid behind a shield.

Li Shu nodded: "I think it's about to explode."

She also shrank her head and hid it behind another shield.

But... what the little girls were worried about didn't happen. The ball was spinning very fast and crazily, but it didn't explode until there was no more white gas coming out.
