The night was already dark, and Lu Ren finally coaxed Cai Yan to sleep, and then he raised his hand and slapped himself a few times.

"Why do you have this mouth when you're full? In my time, there were music players, and cheaper MP3s could be bought for dozens of dollars, but in this era, ...... Alas, I have been mixed in this era for so many years, but sometimes I still subconsciously say some of my thoughts from that era. ”

Shaking his head and sighing, Lu Ren was ready to find a place to rest...... It's ridiculous to say that Lu Ren is now three wives, namely Cai Yan, Minchan and Mi Zhen. But Cai Yan's room was sleeping with two little babies who were just one year old, and Lu Ren was afraid that he would quarrel with these two little ancestors if he ran in, so he didn't dare to go in; Minchan was sent by Lu Ren to keep an eye on Sun Shangxiang, and she was not in the mansion at this time; As for Mi Zhen, according to the plan at that time, after the fleet set off from Wu County, it was assigned to Xuzhou, where he received some Mi clansmen. So at this time, Lu Ren can only be "sleepless" by himself.

After a short walk in the yard, I unexpectedly ran into Shirley. The pair of "senior brothers and sisters" chatted casually for a few words, and Lu Ren casually told him what he had just said in front of Cai Yan. Originally, Lu Ren just regarded this as a self-deprecating pleasure, but Shirley said to Lu Ren after thinking about it: "Master, in fact, with our current conditions, we can make the most basic audio player materials. ”

Lu Ren was immediately stunned, but immediately reacted, and said in surprise: "Shirley, what you said is ...... The earliest gramophone? Okay, huh? Do we have this condition now? I don't know much about anything else, though. But I know we can't make semiconductors or anything like that right now. ”

Shirley shook her head and explained to Lu Ren by the way. In fact, the earliest phonographs did not have high requirements for semiconductors. And with the current conditions here in Yizhou, it is relatively simple, or relatively simple, that semiconductor components are not impossible to get. After Shirley's analysis, Yizhou's existing conditions can actually produce the kind of record player in the early 20th century...... At that time, the records used were like rubber products, and Yizhou's like rubber industry has also begun to take off, thanks to the rapid growth of Yizhou's population last year, and many places have recruited corresponding people.

After hearing this, Lu Renke was really dumbfounded. Then he asked Shirley in a very uncertain tone, "I said, are you really sure we can figure out these things that have to do with electronic components now?" ”

Shirley nodded in response, "You can figure it out." In fact, I've been doing some preliminary preparations for a long time. I won't talk about things that are too long-term, only the master. Don't you want us to use electric lights at night? ”

Lu Ren raised his eyes to look at a few lampstands in the distance, and said with a wry smile: "Isn't this nonsense?" I've been thinking about it for years! After so many years, I used firelight when I read and write at night, and my eyes are still not short-sighted. It's already rare. It's just Shirley. I'm still saying the same thing, can these magneto-electric ones really be made under our current conditions? ”

Shirley smiled back with a charming smile: "Master, some things do seem difficult, but if we use some compromise or alternative methods, it can be achieved. For example, the generator set can generate large-scale hydropower or thermal power, which we can't get out yet. But with relatively small and light wind power, I dare say we could do it in three years. Its power generation capacity is not very large, though. However, one is that Yizhou is located in a geographical location with sufficient sea breeze resources, and the other is that there are not many places where we need to use electricity for the time being. I roughly calculated it, it is nothing more than the conventional daily electricity in lighting, cooling and heating, and then the communication electricity that we must use, these things are not very powerful. ”

Lu Ren was dumbfounded again for a long time, and finally shook his head and said with a dry smile: "You are an expert in these things, you can watch and do it, but pay attention to our corresponding financial budget...... Ay? We're just talking about gramophones, right? Is this really okay? ”

Shirley smiled again: "Master, if you still have the spirit now, come with me." ”

Lu Ren didn't say anything when he heard this, so he got up and followed Shirley, and came to Shirley's forbidden place in the mansion in a circle...... In fact, it's a laboratory. And this time when he walked in, Lu Ren felt as if he had entered a warehouse of miscellaneous goods from his original era, and there were a lot of messy things.

Looking at Shirley and finding a bunch of things, after assembling them, Lu Ren's facial muscles began to jump uncontrollably. Nima! Isn't this the kind of gramophone that was common in the twenties and thirties of the twentieth century to play a record with a few shakes? However, its volume is larger than those in Lu Ren's image, and it seems that some parts and other things in it are just like what Shirley said before, using a compromise or substitution method, so it will make the volume much larger.

His face twitched for a while, and Lu Rencai asked with a dry smile: "Shirley, do you still have time to fiddle with these?" ”

Shirley was still doing the work in her hands, and she replied, "Actually, this is just a handicap." I just wanted to get the telegraph out. Later, when I looked through the relevant materials, I found that the historical phonograph was Thomas? Edison accidentally came up with it while experimenting with the telegraph, so I used the materials I had at hand to get it. Host, don't you like to play music? and Cai Yan, their musical accomplishments are very good, and I like them all, so I thought that it would be good if I could find a way to spread all this music. ”

"Electricity, telegraph, machine!?"

Lu Ren didn't know how many times his cheeks twitched. To be honest, Lu Ren didn't think about this kind of thing, but he always felt that in the era he was in now, it was tantamount to a fool's dream to get these things out, but he didn't expect Shirley to really have a way to get these things out.

But if you can really figure it out, it is difficult to estimate how much convenience and advantages Lu Ren can get here. Not to mention how important the rapid transmission of information will be in the event of war, it is only said that in peacetime, if the small town of Yizhou in Luren can communicate with several other satellite ports by telegraph, it is very difficult to calculate the convenience and benefits that can be obtained.

Moreover, Lu Ren already has several fleets under his command at this point, and if he can have such a thing as a telegraph so that Lu Ren can keep in touch with these fleets at any time, then there is no need to say much about the benefits in all aspects. At this point, although Yizhou already has a population of 100,000, it is still a force that does not enter the stream. If something really happens, whether we can quickly gather manpower and resources is a very important question.

Lu Ren was stunned here, thinking about all the mess, but Shirley had already assembled the gramophone, which could be said to be the original version, and then took out a record made of rubber...... I have to say that this so-called rubber record can be made just by looking at it like this, but Lu Ren also knows that it is rare for Shirley to make such a thing at this time.

The record was set, and Shirley shook the knob again. And even if Lu Ren didn't know much about this, when he heard the slight clicking sound in the gramophone case, he knew that Shirley was using a clockwork drive mode. When Shirley released the knob and put the stylus away, the record began to rotate at a uniform speed, and the gramophone played a soft and melodious sound.

The sound of the piano made Lu Ren stunned for a moment, and then he was surprised: "Isn't this the "White River Cold Autumn" I taught Cai Yan?" Shirley, did you ask Cai Yan to record a record? Well...... The sound quality is a bit poor, but with the current conditions, it is quite good to be able to record to such a level. ”

Shirley waved her finger and said, "Master, when you are not in Yizhou, it is not difficult for me to find an excuse to invite Cai Yan to play piano music in the room." As for the sound quality, we will naturally improve it in the future. It is impossible to reach the standards of the master's time, but if our development of electric power and related semiconductor components can go smoothly, I think we can still barely reach the level of a record player in the mid-20th century. If it is combined with the corresponding recording studio, it should be able to have about 80% audio fidelity. ”

Lu Renle was happy: "What are you doing with these things?" Do we have to sell record players and records in the future? ”

Shirley responded seriously, "Why not? The profits that can be brought by the cultural industry are also very high, and compared with the general brokerage industry, the cultural industry can expand our cultural influence. As long as you control it properly, your influence will become greater and greater. And not only the Chinese continent, master, you should also take a more long-term view, you must know that the navigation strength you have now can actually go to the Indian Ocean and the Persian Gulf, but because we are limited by population and other aspects, we can't go to those areas for the time being. But if we really reach out at that time, with some goods like this, it will only be easier to open the local market. And it should be far more convenient to use things in the cultural industry to open the way than to use things in the brokerage industry to open the way. Like the music that comes with this gramophone...... What does that mean? Oh yes, music is the language of the world. ”

Lu Renxin said Okay, Shirley really thinks about these things much longer than herself. But I have to say that these analyses made by Shirley seem to have some truth...... (To be continued.) )

PS: (Yesterday's Qingming Festival, everyone can understand the reason why it was not updated, right?) Not much to say about the bottle. In addition, what was pulled out this time was somewhat nonsense, so please don't take it too seriously. ）
