Daming Military Empire

Chapter 229 Draw a blueprint and the world becomes close at hand
Xu Fuyuan and Xia Yunyi carefully comprehended every word Zhu Cijiong said, and looked at the experimental equipment on the table from time to time, their eyes gradually showed excitement, a magical door was opening to them, and countless sparks of wisdom were in their minds flash.

If no one disturbs them, they may keep thinking and researching for an hour, two hours, half a day, a day, or even a few days. Too lazy to spend time trimming his appearance, he is unshaven, like a tramp, and Xu Fuyuan and Xia Yunyi seem to have this fanatical tendency.

Zhu Cijiong tried his best to demonstrate and explain the law of electromagnetic induction to them. Of course, it is not for them to do scientific research. Maybe they will completely understand the principle of electromagnetics in the future, and they can do scientific research after becoming experts in electromagnetics. Steam generators and wired telegraph sending and receiving devices are made.

If they are allowed to continue to think about it, they are afraid that they will go astray and think of other aspects. Zhu Cijiong coughed quickly and interrupted: "You can slowly ponder these principles in the future, but you have to remember, we will go astray." The study of the principles of heaven and earth is not for the sake of research, but for the application of them in practice. This time I let you understand the principle of mutual generation of electromagnetism in order to make something useful to Da Ming. Next, I will Let me show you, you have to watch carefully."

After finishing speaking, he winked at Cao Huachun again, and soon two eunuchs came up with two exquisite wooden trays.This time, two very delicate little things were served, both of which were made of thin iron sheets similar to flintlock springs. One was to fix a small iron sheet to a small wooden frame. One end of the iron piece is nailed to the wooden frame, the other end is slightly inclined upwards, and there is a copper bell under the iron piece; the other is fixed on a thick wooden board, one end is also nailed to the wooden board, and the other end Tilting up slightly, the top of the thin iron plate seems to have a small piece of wood tied to it, but there is a nail under the iron plate.

Naturally, Xu Fuyuan and Xia Yunyi didn't know what these two strange little things were used for, and Zhu Cijiong didn't explain, but operated them by himself. He first buckled the iron block wrapped with gold wire out of the thick wood, and stood it there , and then place the small wooden frame on top of the iron block, so that the iron block just faces the thin iron sheet on the small wooden frame.

After finishing all this, Zhu Cijiong pointed to the iron-plated wheel and said to Xu Fuyuan: "Fu Zhai, come and turn the wheel."

Hearing this, Xu Fuyuan hurried forward and grabbed the handle of the wheel and turned it vigorously. He had just turned two times when the thin iron piece on the wooden frame was sucked off with a soft 'ding' sound, hitting it right on the ground.

On the little bell.

At this moment, Zhu Cijiong raised his hand and said, "Stop."

Xu Fuyuan stopped quickly, and the thin iron piece bounced back.

Zhu Cijiong ordered again: "Turn around again."

Xu Fuyuan quickly turned again, but the thin iron piece was naturally sucked off again, and it hit the small bell with a soft sound.

Zhu Cijiong raised his hand again to make Xu Fuyuan stop, pointed to the small wooden frame and asked, "Think about the use of this thing."

This question really stumped Xu Fuyuan and Xia Yunyi, wouldn't they be able to ring the bell? If you want to ring the bell, just knock it with your hands, it's much easier than this.

Seeing that they were thinking hard and making no progress, Zhu Cijiong could only point to the golden thread and remind him: "What if the golden thread is very, very long?"

If it grows for several miles or tens of miles, it will naturally have many uses, and the number of times of each sound is different, and it can convey a lot of simple information, but Xu Fuyuan and Xia Yunyi fell into a misunderstanding. It's ten meters long, so it's better to just open your throat and yell faster.

Seeing that they still hadn't figured it out, Zhu Cijiong stopped embarrassing them, and reminded them directly: "For example, directly pull the silk thread from the beacon tower on the Great Wall to the nearby guard post or even the commander. Ring the bell, in that case, you don’t need to light a beacon, and you can even report the approximate number of enemies based on the number of times the bell rings.”

Xu Fuyuan and Xia Yunyi were dumbfounded when they heard the words. How long would it have to be stretched? They couldn't figure it out. How could such a thin silk thread be stretched so long without breaking?Moreover, is it worth the effort to deliver such a simple message?It's better to arrange a few more soldiers to use loud arrows or fireworks to remind them!
Zhu Cijiong saw the doubts in their hearts, but he did not explain immediately, but continued: "Let's not talk about this for now, I will show you again."

After that, he untied the joints of the gold wire, placed the thick wooden board nailed with the thin iron sheet in the middle of the joint, and then wound the gold wire around one end of the iron nail nailed with the thin iron sheet and the other end around the iron nail under the thin iron sheet. On the nails.

After finishing all this, Zhu Cijiong pointed to the iron-plated wheel and said to Xia Yunyi: "Yizhong, you come to turn the wheel this time."

Hearing this, Xia Yunyi hurried forward and grabbed the handle of the wheel and turned it vigorously. The loop of the gold wire was broken, and there was no electricity in the coil, so the thin iron piece naturally did not move at all. With the experience of the previous experiment, the results were different. , he was no longer so panicked, but thought carefully about what was going on while turning the wheel.

Zhu Cijiong didn't intend to test Xia Yunyi, but needed someone to keep turning the magnet to get electricity on the gold wire. He didn't care what Xia Yunyi was thinking there, but walked forward and gently pressed the button on the thick wooden board. The thin iron piece, as soon as the thin iron piece comes into contact with the iron nail below, the coil is energized, and the thin iron piece on the wooden frame is naturally sucked down again, and with a 'ding' sound, the small bell below is rang again .

He didn't stop there, but pressed it every two seconds, and the little bell of 'ding', 'ding', 'ding' rang rhythmically with his pressing.

Xu Fuyuan and Xia Yunyi had never heard of such a miraculous thing. Could it be that the emperor really has supernatural powers!They were stunned for a moment, staring at the simple button and the ringing bell in Zhu Cijiong's hands, completely losing their ability to think.

Zhu Cijiong didn't expect that a simple switch could shock Xu Fuyuan and Xia Yunyi to such a state, he quickly explained: "It's actually nothing, as I said just now, Jin
When the loop formed by metal does the movement of cutting the magnetic induction line, electricity will be generated in the metal loop. This loop must be connected. Once it is disconnected, it will not be a loop. What I am doing now is to connect the loop. It was disconnected, disconnected and connected again, the gold wire was powered up and down, and the thin iron piece naturally went up and down again. "

Xu Fuyuan and Xia Yunyi came back to their senses after hearing the words. They looked at the loop formed by the gold wires suspiciously, but still couldn't believe it.

Nothing is more intuitive than doing it yourself, Zhu Cijiong waved to Xu Fuyuan: "Fu Zhai, come and try."

After all, step aside.

Xu Fuyuan couldn't wait to come forward, imitating Zhu Cijiong's example and rhythmically pressing the simple switch, the little bell of 'ding', 'ding', 'ding' really rang again.

It turns out that it is really as the emperor said, the matter is so simple, there is electricity in the gold wire of the Unicom loop, and the thin iron sheet will be sucked down to ring the bell, and the gold wire will be out of electricity when the loop is disconnected, and the thin iron sheet will be sucked down again. It will bounce back automatically because of the elasticity. This is not because the emperor has any magical power, ordinary people can do it too.

Zhu Cijiong saw that they were suddenly enlightened, and then continued to guide: "Is this way to send a lot of information to the distance?"

Xu Fuyuan nodded involuntarily and said, "If the gold wire is long enough, it can indeed convey a lot of simple information to a long distance."

Zhu Cijiong shook his head when he heard the words: "No, not just simple information, any information can be transmitted!"

Xu Fuyuan and Xia Yunyi were shocked again when they heard the words, they even stopped their hands. How could this be possible? What a complicated message can be conveyed by a simple ringing of a bell!

Zhu Cijiong knew that they would not believe it, and then explained: "We can number all Chinese characters, for example, according to the order of thousands of characters, 1 represents Tianzi, 2 represents
Di characters, 3 for mysterious characters, and 4 for yellow characters. There are only two or three thousand commonly used Chinese characters, and the code can be coded up to more than 3000. Only the commonly used Chinese characters are added after the thousand-character text, and a book of Chinese character codes is compiled. , can't any information be passed on? "

It seems to be very reasonable, but there is a question that has to be considered. Xu Fuyuan mustered up the courage to ask: "Your Majesty, please forgive me for being bold, the number is no problem, the previous dozens
It’s easy to say one or even a hundred words, and at most you can press a hundred, but what about hundreds or even thousands of words in the future? How long will it take if you press hundreds or thousands of words continuously? How can you guarantee acceptance One does not fall all right! "

Hearing this, Zhu Cijiong rolled his eyes, and said angrily: "Who said you have to count hundreds or thousands? Have you forgotten the exam questions I gave you? Suppose the party who sent the report

Press the switch according to a certain rhythm, for example, every two seconds, if you press it, the bell rings, it means 1, if you don’t press the bell, it means 0, if you use all four-digit binary codes, nine thousand nine hundred and ninety-nine It takes sixteen intervals, 99 seconds, and only six snaps of the fingers. "

徐孚远和夏允彝闻言又是恍然大悟，皇上的意思他们完全明白了，用四位二进制码1就是0001，2就是0010，3就是0011，9就是1100，12就是0001、0010，123就是0001、0010、0011，3999也就是0011、1100、1100、1100，最多按十来下而已，这样的确不会出什么错。

Their gazes towards Zhu Cijiong couldn't help but become extremely reverent, the emperor is really a man of God, he can even think of such a way!

So far, the basic teaching of Xu Fuyuan and Xia Yunyi has been completed. With their ingenuity, as long as they study hard and work hard, they will definitely become experts in electromagnetism in the future. Simple models of steam generators and wired telegraph sending and receiving devices I have demonstrated them all, and it is only a matter of time before the finished product is produced, when the time comes...

Thinking of this, Zhu Cijiong couldn't help but feel very proud. He looked at the sky outside the window and said proudly: "With this set of tools, distance will no longer be a problem. I will replace the telegraph line
Covering the entire Ming Dynasty and even all the vassal states, when the time comes, what happens anywhere will be spread to the capital within an hour. In the future, there will be no need for postmen to run around to deliver information. No matter how wide the territory of the Ming Dynasty is, Everything is under control, with the telegram, even the end of the world will become within reach! "
