Luo Yangxing had already set off to Zhangjiakou to investigate the matter of the big businessman Wang Dengku, so Xiao Mu handed over the matter of sending someone to the Daimyo's Mansion to verify the authenticity of what Lu Da said, and Wang Chengen's work efficiency was also very high, and he quickly arranged for two people to rush to the Daimyo's Mansion on fast horses - it was nothing more than the principle of "the emperor moved his mouth, and the lower ran to break his legs", since it was an errand that the emperor personally ordered to do, there was no way to not be inefficient in the execution below. Pen, fun, and www.biquge.info

Of course, the convenience of transportation in ancient times could not be compared with the highways and railways in later generations, so even if Xiao Mu, an errand ordered by the emperor, it would take two or three days to send the results back - including both the time of the people sent to hurry, and the time for them to visit and investigate in the Daimyo's mansion, it can be said that two or three days to complete this order was extremely efficient in the time and space of the Ming Dynasty.

Of course, Xiao Mu, who left the Beizhen Fusi Imperial Prison at this moment and got into the carriage back to the palace, didn't feel that it was efficient anyway, after all, there were countless ways to be much faster than now in the future generations, for example, you could make a phone call to the official government over there of the Daimyo's Mansion and let the people over there investigate, and then use the phone to report the results of the investigation to yourself.

"It seems that it is necessary to strengthen the level of scientific and technological development of the Ming Dynasty...... Xiao Mu pondered in his heart, and even had the idea of inventing the telephone for a while.

"The principle of the telephone is nothing more than a handset, a microphone." Xiao Mu recalled the knowledge he had learned in middle school physics class, "The principle of communication is also very simple: the sound of people speaking is transmitted to the microphone, which is equipped with magnets and coils, which can convert the vibration of sound into electrical signals, and then the electrical signals are transmitted through wires and cables. After arriving at the other party, they go through a reverse process on the same principle at the earpiece, which also has magnets and coils that can convert the electrical signal back into vibrating sound......"

Xiao Mu nodded involuntarily, he was very satisfied with his solid mastery of knowledge, as for why not do it in one step and directly invent a mobile phone or the Internet? Xiao Mu also knows that things have to be gradual, you can't just think about running before you learn to walk, right?

It's just that although Xiao Mu studied science in middle school, he studied the "pseudoscience" of economics after going to college - yes, Xiao Mu often lamented that economics is pseudoscience, after all, economic activities are dominated by "people", and "people" themselves are very complex and fickle animals, and it is simply impossible to summarize the laws of people's economic activities to form laws, so even in the era when Xiao Mu's economy was very developed, The various models and theories of economics have obvious limitations and can only be valid for a country in a particular period and situation.

Therefore, Xiao Mu only has such a superficial understanding of the basic principles of the telephone, and there are still countless gaps between being able to create a finished product.

"Magnets should have existed in the Ming Dynasty, and the coil is nothing more than a coil of metal wire wrapped around a magnet, which should have been made in the Ming Dynasty, but with a magnet and a coil, what should I do?" Xiao Mu found that relying only on the little knowledge he had in middle school was definitely not enough.

In fact, it is true that the coils on the magnets in later generations are indeed metal wires, but they are all enameled wires, that is, evenly wrapped with an insulating layer on the outside of very thin metal wires, which is almost impossible to do in the Ming Dynasty, of course, with Xiao Mu's half-hung knowledge level, this has long been forgotten.

"Maybe Lin Yi knows, ask her when you go back." Xiao Mu, who was sitting in the carriage and thinking wildly, quickly returned to the palace, and he didn't even feel the bumps brought by the ancient carriage with extremely poor shock absorption performance.

After returning to the palace, Xiao Mu came to Ringo's dormitory as soon as possible, and after briefly telling the story of Lu Da, he told Ringo about his great idea in the carriage.

"You think you're studying economics, so you don't know much about the specific structure of the phone, so that's why you came to ask me?" After listening to Xiao Mu's words, Lin Yi asked in a confirmed tone.

"yes." Xiao Mu gave an affirmative answer without thinking about it.

Then Xiao Mu's extremely affirmative answer helped him get a feather duster in the next second-the feather duster newly bought by Lin Ye in the Sunrise Palace before yesterday finally came into use, because after all, it was to discuss the invention of the telephone, so it was still the old rule at this time, and the palace maids and eunuchs who were waiting were all sent away, so Lin Ye could clean up Xiao Mu without any scruples.

"Wishful thinking! Are you mentally retarded? Lin Yi felt that he was going to be confused by Xiao Mu's anger, and corrected it again, "No, you are an idiot, but there is a limit to being stupid." You studied economics, so you don't understand the structure of the telephone, so why don't you use your brain to think, what am I studying? ”

Xiao Mu woke up like a dream at this time, "Yes, Lin Yi is a Chinese professional, studying all kinds of ancient literature, how can he understand the principle and structure of the telephone......

Moreover, Xiao Mu also thought of one point, that is, Ringo traveled in 2333, and in 2333, things like telephones would have been eliminated long ago, even in 2007, where Xiao Mu was located, the usage rate of mobile phones was already very high, and the number of people who used wired telephones in daily life has gradually decreased. Xiao Mu secretly pondered in his heart: "It is estimated that people in Lin Yi's era can already use 'telepathy' to communicate and communicate......

Lin Yi looked at Xiao Mu with a phenotype of hating iron but not steel, and asked again: "Moreover, you know that the telephone is about to be invented, so let me ask you, the telephone telephone, there is no electricity, how can you talk?" ”

Yes, if you want to invent the telephone, you must first have electricity, then you need to learn to generate electricity, Xiao Mu tried to recall the principle of power generation, such as "electromagnetic induction", "cutting magnetic field" and other things, and suddenly felt that one head and two big.

Xiao Mu thought in his heart, and smirked "hehe", trying to relieve his embarrassment, but the effect was really not good, Xiao Mu could clearly feel that his already irretrievable image in Lin Ye's mind was now more hopeless.

"Haha, I was all joking." Fortunately, the emperor lived up to his wishes, and Xiao Mu finally thought of a statement that could barely alleviate the embarrassment, "Actually, I remembered the matter of trying the bell sweet potato that I explained to Xu Guangqi before, after so many days, I don't know how it happened, why don't I call him over and ask about the situation, what do you think?" ”
