It must be said that the white crane succeeded. This is the first real thing to turn the knowledge in the later high school physics textbooks into real objects, the simplest and most primitive single-threaded wired telegraph, with a cable length of 2.15 kilometers and an actual straight-line distance of about 1.3 kilometers.

Pure DC, the most primitive and simplest telegraph.

Consumed two stones of fine copper, and five stones of stainless steel for the generator shell. There was not enough rubber, so the white crane wrapped the steel wire with lacquer and linen, then protected it with bamboo, and then wrapped it with a layer of linen. Just to test, to test whether the telegraph can be really practical.

In the high school classroom of later generations, a battery, a small lamp, a touch button, and a few meters of wires can solve the problem, but Bai Minghe finally succeeded after spending an unknown number of days and failing in Daming.

The biggest difficulty is not in the copper wire, nor in the contact buttons, but in the generator.

If you can't send a call, every qiē is in vain.

"Hahaha!" Shirona Crane laughed wildly, the excitement in his heart was indescribable.

Yu Qian didn't smile, but his face was very cold, cold and terrifying. He knew that once this kind of thing was available, it would definitely be more perfect, and that just a few miles now doesn't mean it will only be a few miles in the future. The white crane will invest a lot of money to make this thing more perfect.

Come to think of it, the white crane will definitely connect this thing from the White Horse Pavilion to the wharf, and then the Hangzhou wharf, Ningbo, and Suzhou. Even as far south as Fuzhou and Guangzhou, of course, the most likely thing is that Bai Minghe will not hesitate to pay a price to connect this thing with the capital, isn't it just some copper?

If tens of thousands of stones are not enough, then hundreds of thousands of stones.

"Reward, everybody's reward!" After the white crane was excited. The first thing is to reward these little eunuchs who have worked hard for a long time, they are only in their teens, and after being busy day and night, they finally succeeded in making the cable telegraph.

In fact, in the Hereafter. When I was in high school, Shirana Tsuru succeeded in making zuò by hand. Walkie-talkie that can talk a few hundred meters. But in that era, there were all kinds of originals, and you only needed to draw a circuit board by yourself and then work, and the battery was very convenient.

Here, all the qiē needs to start from scratch, and the mere pulling of the copper wire tortures the coppersmiths to the point of madness.

Hundreds of little eunuchs were gathered, most of them belonged to the working class, and only a few very clever belonged to the category of using their brains and hands. These people have an extra copper button on the collar of their clothes than others, which is the difference in status.

"Do you like gold?"

"I like it!" Hundreds of little eunuchs shouted in unison.

"So. Let's play the game again. This time we want to make a big one, stretch out the cement to make a small dam on the waterway, and then use the water conservancy to drive the runner, and then drive the larger machine. If this thing is lit up, then you know that there are some teenage female slaves in this Japanese trade, and this official will give you forty people. and ten thousand taels of silver. Of course, remember that this matter must not be disseminated. Anyone who is not a Ming dare to inquire about this. The white crane made a neck cut.

At this time, hundreds of little eunuchs raised their right hands to the sky at the same time, and shouted in unison: "We are the best!" ”

"Very well, let's do it." With a wave of his hand, the little eunuchs quickly retreated in a neat queue.

Completely militarized steward, a team of his own. A team of absolute loyalty.

"When can it be used to connect Nanjing with the capital?" Yu Qian asked on the side.

"This is just the beginning, two years, maybe three years. Many of the technologies are not mature and need to be re-researched in terms of materials. Such a long copper wire must be connected in sections, but how to connect. How to connect is a question. I have thought about going through the Beijing-Hangzhou Grand Canal from the bottom of the water, and I have also considered going directly to the sea, going around from the sea to Tianjin, and then thinking about erecting it and pulling it to the capital, no matter what I do, it will take a long process. ”

Shira-naka is not talking nonsense, it really takes a process.

Yu Qian asked again: "So, how fast can it be." Send it over today, how long will it take to receive it over there. ”

"How fast?" Bai Minghe smiled: "Lord Yu knows how fast lightning is?" ”

Yu Qian shook his head, he couldn't describe how fast the lightning was.

Bai Minghe raised his hand and snapped his fingers with his right hand: "It's so fast, it's 600,000 miles." So I sent it here, and I received it in an instant. My copper wire will not only be connected to the capital, but also to the Americas 40,000 miles away, as long as there is a place in the Ming Dynasty, there must be my line. ”

"Good line!" Yu Qian only said these two words.

How can it not be a good line, this line represents the control of the force, just like a kite, no matter how far there is a line in the hand, there is an absolute control of the force.

Even if this plan is worth ten years, twenty years, even fifty years.

The telegraph machine is definitely very simple for the parts that modern people can buy casually. But such an invention has undergone decades of changes in history, and Bai Minghe did not say how practical this thing is, because there is no need, and the transmission of information is always a constraint on development.

At this time, someone came to report that Takaya had arrived.

Bai Minghe got up: "Lord Yu, this room is going to be closed." ”

"Good!" Yu Qian understands that whether Bai Minghe can keep it a secret from himself is already a face-saving thing, and he may not need to let others know.

Takaya didn't come alone, and there was an old man with white hair and beard, at least sixty years old, dressed plainly, but it seemed that he was a Confucian from the turban Zafa, but he was not wearing a Confucian robe.

"The old man agreed and invited Mr. Wu to you."

Bai Minghe had forgotten about that bet, he just intended to prove to Takatani that a scholar who can only memorize books is definitely a waste of waste, and a truly good scholar should have a lot of knowledge.

"Yes!" Bai Minghe just gave a sigh of encouragement and didn't stand up at all.

Yu Qian has already stood up, you must know that Wu Hebi is also a celebrity in Daming, Yu Qian's status is high, but as a Confucian minister, he also has to give Wu Hebi some face. But the white crane sat upright, whether it was according to age or respect for the elderly, it was rude for the white crane not to get up.

Wu Youbi lowered his head slightly, turned around and prepared to leave.

"Go, you'll regret it for the rest of your life." Shira-chan Crane suddenly spoke.

Wu Youbi didn't look back, and asked calmly: "Is it like the political envoy of Guangdong Zuobu?" ”

"Nope! Like a dead dog on the side of the street, and the kind that was killed for stealing food. You should know that I, White-Named Crane, have the ability to make your reputation stink! ”

"Shameless ......" Wu and Bi were furious, and turned to point at the white crane.

Bai Minghe slowly lit a cigar: "Let me ask you a question, what kind of factors do you think are needed for the formation of leadership?" ”

"What is leadership?" After Wu and Bi got angry, they quickly calmed down. He knew that he was angered by the success of the white crane, but there was no need to provoke himself with the rumors of the white crane, let alone humiliate himself. Then a curiosity was aroused in his heart, that is, what did the white crane want to do?

"Leadership, in my language, refers to the full use of human and objective conditions within the scope of the jurisdiction, to do what is needed at the minimum cost, and to improve the efficiency of the whole group. In other words, there are many people who are willing to put their lives on the line and give it their all. ”

After listening to Bai Minghe's explanation, Wu Youbi asked unceremoniously: "Is that kneeling for people to see?" ”

"Is Wu Qi also showing the pus to the soldiers?" Bai Minghe also asked rhetorically.

Wu and Bi didn't answer, these two things don't seem to be comparable, but they are very closely related.

"It's a bit too much to say that the sparrow and the bird are a bit of a celebrity, after all, you are also a celebrity. Let's put it bluntly, this time I invite you to come over. I have two ideas, one is to make good use of you, make people wake up and introspect, and then do great things. The second is to make good use of you, if you can't wake up, then in turn I will hit you hard, and take advantage of the momentum to hit you to become my business, very direct. ”

Wu and Bi didn't answer, Gao Gu was a little unhappy, but was pulled aside by Yu Qian.

Yu Qian whispered to Gao Gu: "Listen to it, it must be different!" ”

Wu Youbi recycled the topic just now: "Leadership, just in this Nanjing City, repair the temple of King Yue, the heart of King Yue is leadership, and King Yue will not be destroyed in the Yue family's army." ”

"Leadership comes from fear, profit, and faith. If you don't explain, to explain this kind of detail to a great Confucian like you is to look down on you. However, to borrow a sentence from Confucianism: without examining its origin, it is impossible to understand the changes of the past and the present; If you don't know the gains and losses, you can't get in. ”

As soon as Bai Minghe finished speaking, Wu and Bi and Gao Gu asked in unison: "Whose remarks are these!" ”

"Is there anything wrong with that?"

"The remarks are correct, but such a big argument must come from Confucianism, but I haven't read it Yu Qian." Yu Qian gave Bai Minghe an explanation. Gao Gu also said: "The old man has never read it, he is a famous person in the world!" ”

Bai Minghe only read such a sentence when he was studying management in later generations.

But he doesn't know where it came from!

Historically, this sentence comes from the words of Qingpi Xirui in the "History of Scripture". The Qing Dynasty estimated that it was impossible to exist in this time and space, so it is very likely that this sentence will not appear again.

"Don't talk about this gossip...... Bai Minghe wanted to change the topic, but he couldn't. Gao Gu was a little more serious: "First tell me the source of this?" ”

"I said it. I also read poetry and books. After Bai Minghe replied angrily, he smiled: "It doesn't matter if you believe it or not, I don't explain anyway." I'm thick-skinned, so thick that I can't even grow a beard. So ......" Bai Minghe pointed to his face, looking like a scoundrel.

Yu Qian saw that he was accustomed to the white crane's style, but he believed that this might be the theory of the white crane.

Wu and Bi were completely blinded, what kind of person is this, people have living faces and living skins, and the white crane makes him incomprehensible. (To be continued......)
