"Oh! Didn't I tell you just now? The material is not good, and the tin foil material can only be listened to a few times now. If you want to listen repeatedly, you must use resin material. And if the record is made of resin and well maintained, the sound on the record will be left for hundreds of years." Li Yu said helplessly.

"Ah! If you produce a resin material record you said, hundreds of years later, can my descendants hear my grandmother?" Li Xiuning asked in surprise. He stopped asking the phonograph, and asked about the record curiously again.

Li Yu shook his shoulders and said, "In theory, this is true. Have I tried it? Who knows?"

Seeing that they opened their mouths and were about to ask questions, Li Yu quickly changed the subject and asked, "Li Xueyi is waiting for us below to see the generator, are you going to see it?"

After hearing this, Li Xiuning said without hesitation: "Go, of course, I'll go. This phonograph is just something to play with, electricity, and will be something that will be of great use to the country and the people in the future."

Li Yu agreed with Li Xiuning's words very much. This woman can still distinguish between priorities.

Changsun also agreed: "What the third sister said is reasonable. What you said will benefit the country and the people after the electricity you said will be of great use."

In a tall house dozens of feet away from the villa, they saw a large machine made of steel. The machine spewed out steam from time to time. The three of them were shocked and saw the steam turbine driving the generator set to rotate tirelessly and quickly.

For those who have never seen mechanized equipment, the shocking scene shocked the three of them when they first saw the roar of machinery coming.

After being shocked for a long time, Li Xueyi came to his senses and shouted loudly: "Li Yu's machine is so powerful. Can you run by installing a wheel?"

Li Yu didn't expect that Li Xueyi, a rough guy, could think of a car when he saw the steam turbine generator, and looked at him with admiration.

Seeing that the two girls had come to their senses, he said, "Let's go back and talk, the sound here is a little noisy."

When we returned to the villa, several people sat on the sofa, silent, still shocked by the huge machine we just saw, and didn't know how to speak.

Li Yu did not disturb them and let them come back to their senses. It would be no longer too late to say that.

After waiting for a while, Li Xiuning came to her senses, and then asked in the generator room what Li Xueyi said, "Li Yu, I just heard you say that you should install the steam engine on the wheels and it can run automatically by itself, right!"

Li Yu looked at Li Xiuning proudly and said, "Of course it's OK. In addition, it can be loaded on a boat, which can be driven without wind, and the load capacity is huge. If a train is built and built into a train lane, it will carry 20,000 loads of goods at a time and can reach Luoyang in four hours."

"impossible!"

"impossible!"

"impossible!"

After hearing this, the three of them stood up at the same time and exclaimed in unison.

They never saw the power of machinery. They would never have imagined that the power of machinery had exceeded all their imaginations, so the three people were so shocked.

After the three of them exclaimed, Li Xiuning shook her head and said, "Impossible, are you kidding? Let's not talk about whether you can pull those things for now, but do you know how far Changan is from Luoyang? Are you simply talking nonsense and do you want to be domineering?"

Li Feier, who sat quietly and didn't speak, said a smile on her face after hearing what Li Xiuning couldn't believe. If Li Xiuning knew that the Dragon and Phoenix Empire was developing a high-speed railway and after success, she would be able to arrive in Luoyang in less than two hours, would she be excited to demolish this new villa?

Seeing Li Xiuning questioning her, Li Yu glared at her and said, "Isn't the whole journey from Chang'an to Luoyang only 800 miles? Do you believe it or not? If I tell you that you will arrive in half an hour with the plane, you will not believe it."

After saying that, Li Yu added: "If you haven't seen the power of machinery, don't answer the conversation in a hurry, okay?"

Li Xueyi knew that Li Yu and his master often quarreled, and no one allowed him to make any noise, so he was afraid that he would start. He asked quickly: "Airplane? What is an airplane? Why have I never heard of it?"

Li Yu shook his head and said calmly: "Without strong support for technology, you will never see what a plane looks like for a thousand years."

After saying that, Li Yu was afraid that they would ask questions again. He waved his hand and said again: "Don't ignore the topic of Feitian for the time being. That's not realistic. Even if you create a hot air balloon, the function will not be very useful."

Several people were considering the issue of trains, but no one paid attention to the hot air balloons mentioned by Li Yu.

Seeing Li Yu’s seriousness, Changsun thought about what he saw today, and believed Li Yu’s words very much, but it still exceeded her cognition. Finally, he couldn’t help asking: “If Li Yu built a train, can he really arrive in Luoyang in four hours?”

Li Yu said very simply: "Just use the steam engine you just saw to achieve it. If it can develop into an internal combustion engine, it will take less than two hours, and if the high-speed rail is less than one hour."

"Li Yu, stop talking, you are talking, you will fly to Luoyang in a while." Li Xiuning heard Li Yu say that he would be able to arrive in Luoyang in less than an hour, and couldn't believe it, so she raised the quarrel with Li Yu.

Li Yu was scolded by Li Xiuning, and he stood up and said unhappily: "It's not a bad idea. If you get married in the future, when you come to this home, I will let you see half a stick of incense in Luoyang and let you see it."

"Hey! You know I can't do it now, so I said this on purpose!" Li Xiuning's arrogant temper broke out and replied in discontently.

When Changsun saw the two of them quarreled, he was shocked and found that the two of them were actually quarreling for a small matter?

Li Feier and Li Chun who were pouring water on the side were laughing. It felt like they were quarreling, which was fun.

Li Xueyi looked up at the roof, knowing the virtue of the two of them being together, and he didn't persuade them.

When Li Yu saw the expressions of several people, he felt that he had made a big fuss. He smiled and said, "Forget it, don't you tell me, I'm just incapable of communicating with you as a scientific illiterate person?"

After hearing Li Xiuning said that she was scientifically illiterate, she was about to respond a few words, but thought about everything she saw today. Since he could get all these things, even if he made a train to Luoyang for a few hours, it might not be impossible? I calmed down for a while, and finally believed Li Yu's words, but she still had to make sure of it.

This time, Li Xiuning did not dare to be arrogant anymore, but asked softly, "Li Yu, can you really get to Luoyang in four hours if you build a train?"

Seeing Li Xiuning's eager look, Li Yu hurriedly said, "Yes! But if you want to build a railway, don't think about it for the time being."

Li Yu was really afraid that this woman would get angry and would force herself to help her build the railway.

Li Xiuning immediately asked, "Why don't you dare to think?"

Li Yu asked mockly: "Do you have so much high-performance steel now? Do you know how many thousand steels are needed to make from Chang'an to Luoyang? I tell you that it takes at least 48 million kilograms of steels, which is still a one-way railway. The steels used for bridges with more than 100 steels are not less than this number. In addition, bridge experts, surveying and mapping experts, steel experts, tunnel experts... Do you have so many talents? Finally, I would like to ask you, does the imperial court have that much money?"

As soon as Li Yu finished speaking, Li Xiuning opened her cherry mouth and was stunned and was stunned.

After a while, Li Xiuning sat on the sofa, and a sad look suddenly became silent.

Li Yu's words completely scared her.

The Tang Dynasty only had a national steel production in one year, only a few million kilograms, and most of it was still ordinary pig iron. Even if the weapons used by the army are not popular yet, let alone a thousand kilograms of steel making. What's more, the construction of railways requires steel making or more than kilograms of steel making. Think about 48 million kilograms of steel making and the same amount of steel making. It is beyond her imagination. In addition, there are all kinds of unknown experts and a huge amount of money...

When Li Xiuning thought of this, her scalp was numb.

After hearing Li Yu's words, Changsun and Li Xueyi were also shocked on the spot. The Tang Dynasty needed to use steel produced for many years to build this railway. I dare not imagine it? They no longer believed that the Tang Dynasty could build the train mentioned earlier.

Changsun turned around and looked at Li Yu's indifferent expression. She knew that Li Yu must have a way to solve all these problems, but he was just unwilling to do it. She was embarrassed to say anything, so she asked the maid who brought her to carry her daughter who was playing in the garden and said goodbye.

Li Xiuning looked at the departure of Changsun, and then saw where Li Yu was sitting like a master. A smile suddenly appeared on his pretty face.
