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

Li Shimin silently looked at the increasingly weak motor.

energy?

The term is not difficult to understand, but it is novel.

Just like what Yin Xuan said yesterday, dry words cannot express the power contained in his knowledge.A simple motor has a huge impact on him.

With a bang, with the vibration brought by the rotation, the simple brackets were scattered, and the coil hit the wooden board, making a low sound.

Just like Li Shimin's world view, along with this sound, tiny cracks appeared.

What is the use of this thing?

If it's just such a motor, it's useless.

The four words "Kit Kat and Sexual Skills" are enough to describe it.

But the important thing is not the object itself, but the technology.

Without Yin Xuan's explanation, Li Shimin can imagine a water wheel that he can turn, a carriage that can run without a horse, and even in summer, this thing can also be used to blow the wind - this is what Cheng Yaojin said on the face The little windmill inspired him.

Especially the carriage.

If it is made into normal-sized wheels, even if this speed is not as fast as that of a horse, it is more expensive than long-lasting, and it is an excellent help for transporting grain and grass.

Sufficient food and strong soldiers, with such a thing, Li Shimin has almost foreseen what kind of huge changes will be ushered in in the allocation of food and grass for the Datang army.

"Shopkeeper, no, sir, if you can figure out such a great knowledge, why don't you serve the court?" Li Shimin said slowly, with a cautious tone, "With my master's knowledge, even if the court sets up another government office for you alone, I'm afraid it won't work. question."

Wei Zheng looked at Li Shimin in surprise.

He could tell that Li Shimin was tempted.

There is nothing false about these words.

But he calculated it in his heart, this is not a very exaggerated matter, he pursed his lips, and obediently did not speak.

Yin Xuan shook his head.

Li Shimin asked further: "Why did you refuse to serve the court? With the support of the court, wouldn't your knowledge be carried forward?"

Yin Xuan smiled, then shook his head again: "It's not that I don't want to."

"The current Datang cannot afford it."

Li Shimin was stunned, and raised his hand to pick his ears. He could accept any answer, but this answer made him a little unacceptable.

The Tang Dynasty was rich and prosperous, and all the people came to court. As a result, Yin Xuan said that he couldn't afford it?
"How could Datang not be able to support the store?" Wei Zheng shook his head, unable to deny it, "It's just a little copper and iron."

Yin Xuan raised his hand and knocked on the table, interrupting Wei Zheng's words: "I want to learn a little bit about my knowledge, just prepare a pen and paper like Li Shu did."

"If you want to get started, you have to talk a lot in less than a year."

"If you want to understand some basics, you can't do without [-] drills a year."

"If you want it to be useful, you need at least a million shots in that year."

After speaking, Yin Xuan paused.

"If you want it to be fully effective on this basis, ten million or hundreds of millions a year is just a few more opportunities for trial and error."

Li Shimin swallowed a mouthful of saliva: "Sir, aren't you joking?"

Yin Xuan nodded: "Of course not."

Scientific achievements are all tested one by one in thousands of failures, and these thousands of failures require a lot of resources to support.

Yin Xuan did not exaggerate in terms of the required financial resources.

Just like the motor I made myself, these copper wires and iron rods need to be connected three or four times.If you don't know how to make a motor yourself, if you want to research it, the cost will be at least a hundred times higher.

And these things... are not scientific research achievements, at most they are appetizers to cultivate interest.

Li Shimin didn't believe it all. He couldn't imagine how to do it. He could spend millions, tens of millions, or even hundreds of millions of copper coins a year.

But this is Yin Xuan's knowledge after all, and Yin Xuan's words are undoubtedly very convincing.

"The current Tang Dynasty is so poor!" Yin Xuan sighed and sighed.

He grabbed the tomato, pulled out the copper and iron rods, and took a hard bite towards the uncontaminated area: "Besides, I'm too tired to study those things. I'd better manage my restaurant well."

"After talking for a long time, what do the guests want to eat?"

A few of them didn't speak.

Yin Xuan raised his eyebrows, a little surprised: "Aren't you planning to eat today?"

Cheng Yaojin focused his head heavily: "Eat, why don't you eat!"

"Shop, please come to the Huoyan Mountain, Desert Wind and Sand, Gold Inlaid Jade, and Green Pepper Meat. Press our heads, and each of us will serve two bowls of rice."

"Another half catty of Yu Jingqiu."

Yin Xuan stood up with an innocent face: "The wine is gone."

Cheng Yaojin tilted his head back and looked at Yin Xuan in shock.

Such a good wine is gone!
Yin Xuan didn't expect to be able to sell so fast, even if he had set a limit, he couldn't bear the animals coming to drink every day, and on the night when Zhou Bu came, he didn't set a limit.

Zhou Bu alone drank more than half a catty.

The little that Li Shimin drank yesterday was the last to be sold. There were still more than two taels in the kitchen, but they were reserved for cooking.

Cheng Yaojin sighed in disappointment, took a bite, and bit off the stick in his mouth: "When will the store's new wine come out?"

Yin Xuan thought for a while: "Wait a year later."

"I've also invited some people recently, and when the time comes to build a wine shop, there will be no need to limit the wine in the future."

Draw a cake.

Cheng Yaojin felt that he was being scented, and the expression on his face gradually eased: "That's good, that's good."

"No wine today, no bar."

"Please trouble the shopkeeper."

Yin Xuan turned and went to the kitchen.

Li Shimin looked at the things on the table, waved to the maid, and asked her to reassemble the thing, and then carefully took it back.

Then he turned his head and looked at Li Shu: "What is the electromagnetic induction you just mentioned?"

Li Shu replied in a low voice: "Brother Zhengyang didn't teach us that thing, he just mentioned it casually once, saying that electricity is a natural phenomenon and a kind of energy source, and he casually said something about electromagnetic induction."

"I thought Brother Zhengyang was doing electromagnetic induction today."

Li Shimin nodded thoughtfully: "Then what skills have you learned from the store now?"

Li Shu replied: "It's still power and light. Besides that, it's arithmetic, and there are some knowledge about biology and geography."

biology?

"What is this creature?" Li Shimin asked curiously.

Li Shu blushed slightly: "It's a subject that studies animals and plants." Li Lizhi also blushed.

What are you blushing for?
day frozen?

Wei Zheng keenly noticed this strangeness, but he was obedient and knowledgeable and didn't ask any questions.

Li Shimin thought deeply and didn't notice.
