After the printing was completed, Ye Han picked up the two printed papers, turned them over and saw the contents. As expected, he exclaimed again.
"It's so realistic, it's exactly the same."
“The key is speed.”
Upon hearing this, Ye Han added, "This is color printing, so it's relatively slow. If you're just printing text, black and white would be faster."
"In that case, the books over there are very cheap."
"Yes, if books, paper and other learning materials are not cheap, it will be impossible to universalize nine years of compulsory education."
"Is this the improvement in productivity you mentioned?" When the emperor saw the efficiency of the printer, he suddenly thought of the previous improvement in productivity for some reason. Although Ye Han did not explain the word in detail, because the word was mentioned relatively frequently, the emperor noticed these three words very keenly.
Although I have never heard of it, the magic of Chinese characters lies here. After reading these three words repeatedly, I can understand what they mean. It’s just that this concept has always been very abstract to me before. Today, when I saw the printing speed, I suddenly understood what productivity improvement is.
“Yes, that’s a small part of it.”
"Can this be popularized in Da Yue? Or even manufactured?"
"No, it's OK for small-scale personal use, but not for large-scale deployment."
"Why? Even if you can't make it, why not just buy it?"
"Your Majesty, this isn't just a printer issue. We can buy a printer. With the royal family's financial resources, we can easily buy one that's large enough for daily use. But this isn't just a printer issue.
For this small machine to work properly, there needs to be a complete infrastructure behind it.
This requires a complete industrial system to support it. Most basically, printers and computers require electricity to start up. Electricity cannot be generated out of thin air, so power plants are needed. The most basic and simplest one is a thermal power plant, which requires a large amount of coal, which in turn requires the support of mining and surveying technologies.
Even if these are solved, there is still the issue of electricity transportation, which requires wires. A small wire is a whole industry chain, and finally there is the need to lay wires and cables across the country, and finally there is the issue of sockets, etc. So many things are needed to support the launch of this small machine.
The most important thing is that this is just turning on the phone, but turning it on doesn't mean it can be used. For example, just now my daughter-in-law transferred a picture from her phone to the computer. Have you ever thought about how it was transferred?"
"How did it get spread?"
"When it comes to the internet, the industries involved are even more numerous and complex than electricity, with each link interconnected. This is not something that can be developed overnight. It requires theory, technology, talent, and the establishment of a complete industrial system by the country, but building an industrial system is incredibly difficult."
"How difficult is it?" The emperor had already given up his idea when he heard about electricity. The thing is good, but it has to be usable. However, this did not prevent the emperor from being interested in Ye Han's words.
"Let's put it this way. Even in the world over there, among the more than 200 countries and regions in the world, there are only a handful of countries that possess a complete industrial system, or that have the ability to build their own industrial system. And they are all powerful countries over there, the kind that have a say in the world."
The others were silent after hearing this. Yes, even a country in that era could not be built, let alone Dai Viet, which was even more far behind.
"It seems that I have no choice but to give up with great pain." The emperor sighed.
Ye Han didn't respond, and it was not appropriate to continue the conversation.
"Father, Mother, don't you want to visit this house? Let's go and take a look together. I'm also quite interested. There are many things here that I don't recognize." The prince suggested.
"That's right, we have to take a look. I want to see how many amazing things the people over there can create."
"Then I'll be your tour guide." Ye Han took over.
“What is a tour guide?”
“I’m responsible for explaining.”
Everyone nodded in understanding. "We do need you as a guide," the emperor said, his mood having calmed down. He continued to smile. The others laughed too. The silence seemed to have vanished, and the relaxed atmosphere of dinner returned.
There is no way around it. The emperor's mood is the barometer. Whether it is cloudy, sunny, or stormy depends entirely on the emperor's mood.
"Where would you like to start?"
"Let's start in this study."
"Actually, most people don't know about this study, probably the only thing that's there is the computer and the printer. If you want to talk about anything else, it's only the water bar." Ye Han said as he came to the water bar in the study.
"There's a water purifier here. You can directly connect it to hot water and choose the temperature yourself, like this..."
“That’s quite convenient.”
"Well, when it was designed, it was made easy to make tea so that we wouldn't have to run outside all the time."
Yue Chengyu listened very carefully, because he didn't know how to use it before. Since moving here, Yue Chengyu felt that he needed to learn a lot. Fortunately, Yue Chengyu had a good memory and learned things quite quickly.
Ye Han brought the group to the kitchen, an open kitchen just behind the dining table.
"I just noticed this place while eating. Sister-in-law, what is this for?"
"This is the kitchen."
"Kitchen? Putting the kitchen inside the house? How do we deal with the cooking fumes? Won't it fill the whole house?"
"No, look at this. There's a range hood above the stove. Turn it on when you're cooking to suck out the fumes."
"I see."
"What about this?"
"This is a refrigerator, you can store food, this side is for keeping fresh, this side is for freezing... Ye Han finally finished the introduction after a long time."
"Isn't this just a small ice cellar?"
"Yes, that's understandable."
"And this, this is a dishwasher... a gas stove... That's about it."
"This is so convenient! It can save a lot of kitchen maids and servants." Of course, the Crown Princess only sighed. After all, these things were just to make life easier and reduce the burden on the family. But for the people present, it was completely dispensable. After all, even if they didn't have these things, they didn't have to do it themselves.
Just like Yue Chengyu's soul-searching question to Ye Han, if you buy all this, what will happen to the servants? Will they lose their jobs?
So, you can sigh, but you shouldn’t be envious. After all, it doesn’t make much difference whether it exists or not. You just think it’s magical.
