Li Yu looked at Li Xiuning and Li Xueyi's stunned appearance and knew that they were shocked. When they were about to pat their butts and leave, they were stopped by Li Xiuning who came to his senses.

"You! You were just talking about joking, or were talking nonsense!" Li Xiuning was a little disbelief, with a look of doubt on her face.

Li Yu curled his lips and said, "If you believe it or not, farmers in some areas have used this manure to increase their yields. Don't you know?"

When Li Xiuning heard strange words, she felt that these words sounded very noble, which made her interested.

"No, I'm asking what vitamin K, vitamin B, and what nitrogen, phosphorus and potassium are you talking about, and what are you doing?" Li Xiuning's face was filled with joy and a little confused.

"For example, can people survive by drinking water? You can't take it, and the same is true for plants. People eat food, vegetables, and meat, which are all nutrients for the human body. Nitrogen, phosphorus and potassium are actually necessary for plant growth. Forget it, you don't understand, just do what I want. When the crops are harvested, you will understand." Li Yu explained the importance of manure water. Later, he felt that they didn't understand, so he still asked them to see the autumn crop harvest.

"It's impossible to communicate with you scientific illiterate people." Li Yu sighed and said helplessly, then quickly patted his butt and left. This woman has been asking for trouble for herself these days. If she doesn't leave, she will be in trouble for her if she has nothing to do and then her own trouble.

"Li Xueyi, the bastard just now said what did we come from?"

Li Xiuning finished asking word by word with gritted teeth, her face was white, red and blue.

"That boy dares to say that we are scientific illiterate or something."

After Li Xueyi finished answering word by word, his face was dark, green, and green.

...

Three days later.

Under the three shifts of craftsmen, two water trucks were successfully built.

Farmers and craftsmen used simple lifting tools to lift the water truck, and then steadily installed the water truck in the slot in the middle of the boulder. The craftsmen skillfully fixed the water truck, so that another water truck would be installed again.

Li Yu stood on the shore and watched the busy scene of the rivers and canals. When he looked at the new technology he brought to the Tang Dynasty, he felt a sense of spiritual satisfaction. Last time, because of improving his strength, his not very stable mood has now become a little stable.

At this time, Li Xiuning came over, stood behind him, and suddenly spoke, "Li Yu, your field is a seed base, which is related to the lives of the people in the future. These water trucks will be used by your farmers first! It will definitely not affect the seed harvest this year. All the crops in my field, such as the 1,000 acres of seed base, will I water my field again!"

Li Yu turned around and smiled and said, "It's okay, the water truck I designed this time is very large, and the amount of water it extracts is twice that of the old water truck. According to the calculation that a water truck can water at least 50 acres of land a day and a night, I think the three water trucks will water all the farmland in a few days.

In fact, corn irrigation takes three to four times a year. Potatoes and sweet potatoes are not too drought, and they don’t delay your irrigation in the fields.

Now three waterwheels have been made in less than seven days. Nowadays, craftsmen are making waterwheels more and more convenient, and the speed will be faster in the future. Don’t worry, it will not affect your field watering!"

There are more than 100,000 acres of fields under Li Xiuning's name. The water trucks that were made to irrigate the land may not be enough. Li Yu knew that she cared about the lives of the farmers under her name. He said this on purpose, which was actually to comfort Li Xiuning.

When Li Yu saw Li Xiuning hear her words, the sad face disappeared, and then saw her shaking her head quickly. It seemed that she knew it was impossible to do it.

"I must find a way to try not to let the farmers be affected by this drought." Li Xiuning seemed to be saying to Li Yu, and seemed to be muttering to himself.

When Li Yu saw Li Xiuning's situation, he had an idea and said, "Actually, Xiuning, you can open a farm tool factory separately. First, you can increase your income, and second, you can also study new farm tools. In the future, I can design several types of advanced farm tools for you, so that new farm tools can be slowly released and a large number of various craftsmen can be cultivated."

When Li Xiuning heard this, her face suddenly showed joy and said, "Your idea is very good. You can develop new agricultural tools and cultivate talents. In the future, the other courtyards will no longer lack craftsmen, and there will be no situation like this year. It is really a wonderful beauty."

After saying happily, Li Xiuning looked gloomy on her face and said, "But this requires a lot of money, where does so much money come from?"

Li Yu immediately rolled his eyes to Li Xiuning and asked, "You saw such a strange thing in my house. Didn't you think of the way to make a fortune? What are you thinking about in your heart every day?"

"I'm a princess! How can I do business with merchants? No, no." Li Xiuning shook her head as she said.

"Oh, aren't soap and cauliflower sold well? You might as well stop, don't buy items on the street! How good is it to go back to the era of bartering." Li Yu didn't expect that Li Xiuning would discriminate against businessmen and said sarcastically.

Li Xiuning did not care about Li Yu's sarcastic words, but said with great righteousness: "There is only so much wealth in the world. I have made a lot of money. What should the country do if I make a lot of money? There are many things you use. If you use more, the court will use less. In the future, the country will build roads, water conservancy facilities, and military construction... All places need money, and I can't do this."

Li Yu was shocked after hearing this. He didn't expect that Li Xiuning would say such ridiculous words today, but at the same time he felt something was wrong. He hurriedly said: "Siu Ning is your idea or everyone's idea?"

"Of course it's everyone's idea." Li Xiuning finished speaking casually. She looked at Li Yu with her eyes wide open. She found such a simple question. Why didn't he know, is this still the same knowledge?

After hearing this, Li Yu carried his hands behind his back, looked up at the sky at 45 degrees, and felt a sense of loneliness all over his body.

Finally, he sighed heavily and said, "My God! How can I live like a smart person in the future? Am I the only one who understands me in the Tang Dynasty? Are you allowed to be alone for the rest of your life?"

Li Yu finally understood why the status of merchants in ancient times was so low? It was these people in power who did not understand what wealth was. They felt that merchants made the world's wealth, which made the country's finances not enough money, and became angry. This would restrict the activities of merchants everywhere and give merchants a low status.

Li Xiuning saw Li Yu standing there and sighing, showing off his appearance, ignored him. Instead, he was silent for a long time, with a strange expression, and said, "Isn't what I said right? Isn't the world rich? If you make more money, will the country's wealth be less?"

Li Yu sighed and said, "Xiu Ning, I ask you, did you have so much money in ancient times, during the Xia and Shang dynasties?"

Li Xiuning said with a brow and said, "That's definitely not as much as it is now. Isn't it very strange?"

Li Yu raised his face and said, "You know that it is not as much as it is now, but where did the extra wealth come from?"

"I don't know, how could I know." Li Xiuning couldn't explain it clearly, so she just started to play tricks.

Seeing her cheating look, Li Yu understood that she did not know the reason for wealth, and read out a small paragraph in the theory of wealth: "To create wealth, you must consume productivity. Or to put it simply, productivity is constantly working, and new wealth is constantly losing. It can be seen that the generation of new wealth is conditional on the consumption of productivity. Therefore, productivity creates wealth."

After Li Yu finished reading, he looked at Li Xiuning who was demented and ignored her, but said slowly: "In general, people create wealth in labor. Think carefully about it, we grow high-yield grains. Isn't the productive grains not wealth?"

Li Xiuning was silent for a while, her eyes lit up and she said, "I seem to understand a little now. What you mean, does it mean, clothes, food, and houses... are all kind of wealth, and coins are not the only wealth."

After hearing this, Li Yu felt that this girl was not too stupid. She used a simple Liezi to tell her what wealth is, and she quickly understood the types of wealth.

Li Yu felt that in this ancient era, everything was extremely backward, including thoughts. He sighed and said, "Yes! You produce more food in the field. You can raise pigs, cattle, and various livestock. These things can be exchanged for everything you need. Therefore, labor production creates wealth, because the land can grow wealth in circulation, so wealth is constantly increasing, not what you think is fixed."

After listening to the principle of wealth described by Li Yu, Li Xiuning immediately understood it. Her eyes showed her spirit and said, "If you say this, I understand. In fact, the greatest wealth is still people. Without people, wealth will not be formed, right!"
