"That's great. The water truck has finally been tested successfully. I will inform the court immediately and promote the water truck as soon as possible! I will quickly resolve the crisis of the severe drought in Guanzhong." Li Xiuning looked at the well-running water truck and shouted excitedly.

After saying excitedly, Li Xiuning took a long breath. She did not expect that the problem of severe drought in Guanzhong would be solved so easily.

"Sister, this new water truck is really good. It has a large water output, a simple structure, and saves manpower. I think I can report it to my father immediately and promote it as soon as possible! I believe that the father will let his father sleep peacefully for the severe drought in Guanzhong." Li Er watched the craftsmen and farmers happily step on the water truck, and was dancing happily.

"Hehe! Second brother, you don't have to be too anxious. Sit down and drink a little water before talking!" Li Xiuning couldn't help but smile when she saw Li Er's cheerful look, and poured Li Er a glass of water with her own hands.

Li Yu saw the cup of tea that Li Er came with actually contained mutton oil and various seasonings of Wuwei soup, which made him feel dry and vomited.

"Thank you, third sister." Li Er took the Wuwei Soup and drank it all, then sat down and smiled at Li Yu, "This kind of water truck can be promoted thanks to Mr. Li's efforts, which will be the first contribution in the future!"

Li Yu looked at Li Er in surprise and drank the Wuwei Soup with sheep oil. He felt nauseous and vomited. He took a few deep breaths to calm down the tummy in his stomach.

Li Yu waved his hand and said indifferently: "I don't need it. You three should take the credit for the water truck! It's useless for me to ask for so much credit, isn't it?"

Li Er and Li Xiuning looked at each other, but looked helpless. This man had no desires and no choice but to help.

However, there are also benefits. This time Li Yu did not receive the credit, which would make his father let go of his worries and say that he did not have the ambition to establish a family.

"You can come and try the new tea I just cooked." Li Xiuning knew in her heart what her father was worried about and was not asking about the credit. She immediately gave Li Yu a cup of cooked five-flavor soup and asked him to come and taste it.

"I can't enjoy your five-flavor soup. I've been ruined by you." Li Yu looked at the Wuwei Soup with sheep oil in the teacup. When he saw the feeling of Li Er drinking it just now, he shuddered and waved his hand to refuse.

"No, what's wrong with the tea I cook? Why are you wasting tea leaves? What do you mean?" Li Xiuning heard Li Yu say that he had ruined tea leaves, and stared at the apricot to get angry.

"When I have the chance, I will let you see what's going on in our Chinese tea culture." Li Yu didn't care about Li Xiuning's anger, but smiled maliciously.

"Just drinking tea, what kind of tea culture did you create? Is it the same as your distilled alcohol that day?" Li Xiuning asked in confusion when she saw Li Yu's malicious smile.

"I don't have time to explain to you now. When the water truck is finished, I will let you taste what the tea culture in China is." Li Yu did not explain. After a while, he let her taste dozens of tea cultivated in the space. She would know how to drink tea, so that she would not drink the five-flavor soup every day.

"Okay! Is the tea you made so magical?" Li Xiuning agreed. The main reason was that she had seen Li Yu's continuous means many times and had expectations for the tea culture he mentioned.

Uncle Zhang and Li Xueyi got off the waterwheel, and the craftsmen and farmers continued to experiment with the performance of the waterwheel.

One hour later!

Several craftsmen with experience in manufacturing water trucks came to report that the efficiency of new water trucks is definitely more than twice as efficient than the original old water trucks, and the production process is not complicated and it is easy to popularize.

After listening to the craftsmen's reports, Li Er stood up excitedly and said, "Sister, I'll go back now. This year, the severe drought in Guanzhong has caused my father to eat and sleep hard these days. Fortunately, the trial production of the water wheel is successful. I will go back to the palace and report to my father, and strive to let the court come up with a promotion method early!"

There is not no reason why Li Er is so concerned about promoting water trucks. Speaking of which, the reason why Li Er was able to fall at a disadvantage in every battle with Li Jiancheng was mainly because he made achievements in military affairs and did not show any talent in civil affairs.

In terms of civil affairs, this is exactly Li Jiancheng's strength. Now, under his own leadership, he has finally tried to produce a new water truck and solved the crisis of the severe drought in Guanzhong, so that those civil officials can also see that Li Er's ability to govern the world is not inferior to his elder brother.

Next, Li Er chatted with Li Xiuning and Li Yu for a while about the water wheel, and then hurriedly said goodbye and left.

Li Yu looked at the cheerful smiles of the craftsmen and farmers. The construction of water wheels was different from other things in the past. It was that the production of airplanes and cannons had nothing to do with these people, and it was only helpful to the country's defense and offense. However, water wheels were different. The direct benefit of the manufacturing and use of water wheels was that it could promote the leapfrog development of agriculture, and what the people care most about was whether they could eat enough!

In this era when production and living tools are extremely backward, what farmers in this era want is not material and spiritual enjoyment, but how to fill their stomachs and survive. The current situation is that the backward production tools and underdeveloped agricultural technology have always been a must-fill their stomachs. Sometimes, if the weather is not good, the harvest will decrease. It is common for them to go hungry every winter due to insufficient food.

The effect of the waterwheel not only increases the yield of crops, but also brings about the abundance of food but the growth of population. With the development of population, it will bring prosperity and technological progress. Everything that must be brought about is derived from human creation. If there is no human being, there will be no such thing. Therefore, people are the basis of everything. That is to say, only when you have people can you create everything. The more people, the larger the base, what you can create is more material.

Why did farmers and tenants burst into great joy after seeing the construction of the water trucks? It is because the manufacturing of the water trucks brings a real increase in agricultural output.

When Li Yu saw the cheers of the craftsmen and the people, he was sincerely happy for them. He had only come to this era and did something for this era. Of course, he also gained a lot of faith.

"Li Yu! Mr. Li!!" Li Yu was thinking about the changes brought about by the water truck, but was interrupted by Li Xiuning's intentional shouting.

Li Yu rolled her eyes and asked, "Western accent, what's wrong with you?"

"What a foreign accent, I haven't said you yet. You are so unwilling to do it. You asked the tenant to dig a big hole and get so much manure. Are you planning to stink the person to death?" Li Xiuning heard the stinky smell floating in front of him and kept slapping the smell with his hands.

"Of course it is for the high yield of crops in the seed bases to prepare for increased yields." Li Yu was angry because he interrupted his beautiful desire and said casually.

"Hmph! Is it useful? Just talking nonsense." Li Xiuning looked disbelief.

Li Xueyi, who was standing beside him, also looked confused, waiting for Li Yu to explain why feces can increase yield.

"If you don't understand, don't talk nonsense. Today I will popularize natural science knowledge for you. One quarter of feces is water, and most of the rest are protein, inorganic substances, fat, undigested food fiber, digestive juice residues that have been dehydrated, as well as cells and dead bacteria that fall out of the intestines, as well as vitamin K, vitamin B, etc.

"These components in manure water, after fermentation, become nitrogen, phosphorus, potassium and other elements required for plant growth, can not only provide comprehensive nutrition for crops, but also have a long fertilizer effect, which can increase and renew soil organic matter, promote microbial reproduction, and improve soil physical and chemical properties and biological activities. Of course, manure water must be fermented before it can be used as fertilizer for plants, otherwise many ingredients will not be converted and are not easily absorbed by plants. At the same time, the fermentation of manure water in the soil to a certain extent will produce methane, ammonia and heat, burn the roots of the plants, and cause plant death."

After Li Yu said the effect of the manure water, he smiled and said, "That's why I asked the tenants to dig a hole to let the manure water ferment. You understand."

"My not understand!" Li Xiuning replied casually with a look of surprise when she heard that the feces had such great knowledge.
Chapter completed!
