It must be said that Bai Minghe succeeded. This is the first experiment to convert the knowledge in later high school physics textbooks into physical objects. The simplest and most primitive single-threaded wired telegraph machine, with a cable length of 2.15 kilometers, and the actual straight-line distance is about 1.3 kilometers.

Pure DC, the most primitive and simple telegraph machine.

After consuming the best copper, two stones, and five stones of fine steel are used as the generator shell. Without enough rubber, Bai Minghe wrapped the steel wire with paint and linen, then protected it with bamboo, and then wrapped a layer of linen. Just for the sake of testing, test whether the telegram function can be truly practical.

In the high school classroom in later generations, a battery, a small light, a contact button, and a few meters of wire could solve the problem. However, Bai Minghe finally succeeded in Daming for countless days and many times.

The biggest difficulty lies not in the copper wire, nor in the contact button, but in the generator.

If you can't send out the electricity, everything will be useless.

"Hahaha!" Bai Minghe laughed wildly, his excitement in his heart was indescribable.

Yu Qian did not laugh, but his face was very cold and terrifying. He knew that once this kind of thing was available, it would definitely be more perfect. There are only a few miles at the moment, which does not mean that there will be only a few miles in the future. Bai Minghe will invest huge amounts of money and make this thing more perfect at all costs.

I think that Baiminghe would definitely connect this thing to the wharf from Baima Pavilion, then Hangzhou wharf, Ningbo, Suzhou. Even to Fuzhou and Guangzhou, of course, the most likely thing is that Baiminghe would connect this thing to the capital at all costs. Isn’t it just copper?

Is it enough to be tens of thousands of stones?

"Everyone appreciates it!" Bai Minghe was excited. The first thing he did was to reward these young eunuchs who had worked hard for a long time. After being busy all day and night, the cable telegraph was finally successful.

In fact, in later generations, in high school, Bai Minghe successfully made the simplest walkie-talkie hand-made into the simplest walkie-talkie that could be called hundreds of meters. But in that era, there were all kinds of originals, and you just need to draw a circuit board and work by yourself. Batteries and other things were very convenient.

Here, everything needs to start from scratch. Just pulling copper wires will torture the coppersmiths torture madly.

Hundreds of eunuchs were gathered together, most of whom were of work grade, and only a few were very smart ones who were brain-on and hands-on. The collars of these people's clothes were one more copper button on their collars than others, which is the difference in identity.

"Do you like gold?"

"I like it!" hundreds of eunuchs shouted in unison.

"Then let's play again. This time we will make a big one, use cement to make a small dam on the waterway, and then use water conservancy to drive the wheel, and then drive a larger machine. If this thing is bright, then you know that in this Japanese transaction, some female slaves in their teens will be given to you forty people. Add 10,000 taels of silver. Of course, remember that this matter cannot be circulated. Anyone who is not the Ming Dynasty dares to inquire about this matter." Bai Minghe made a neck-cutting action.

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

"Very good, go and do it." Bai Minghe waved his hand, and the little eunuchs lined up in an orderly queue and quickly retreated.

Completely militarized management, Bai Minghe's own team, an absolutely loyal team.

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

"This is just the beginning, two years, or three years. Many technologies are not mature, and the materials need to be studied further. Such a long copper wire must be connected one after another, but how to connect it is a problem. I have considered going through the water from the bottom of the Beijing-Hangzhou Grand Canal, and also considered going directly to the sea, going around from the sea to Tianjin, and then thinking about raising it to the capital. No matter what, it will take a long process."

Bai Minghe did not speak nonsense, it really took a process.

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

"How fast?" Bai Minghe smiled: "Master 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 only six hundred thousand miles at a time. So I sent it here and received it in an instant. My copper wire will not only connect to the capital, but also to America 40,000 miles away. As long as there is a place in the Ming Dynasty, there will definitely be my wire."

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

How could it be a good line? This line represents control, just like a kite. No matter how far a line is in your hand, it has absolute control.

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

Telegram Express is definitely very simple for parts that modern people can buy casually. However, this invention has undergone decades of changes in history. Baiminghe has not talked about 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 the valley was here.

Bai Minghe stood up: "Sir Yu, this room is about to be closed."

"Okay!" Yu Qian understood that Bai Minghe was already giving face to not keep his secret from him, and it may not be necessary for others to know.

Gao Gu did not come alone. He also came with him with a man with a hair and beard that was completely white, at least sixty years old, and was wearing a simple old man. He only looked like a Confucian scholar from the way he tied his headscarf, but he did not wear a Confucian scholar robe.

"I have invited Mr. Wu to you as promised."

Bai Minghe had forgotten that bet. He just planned to prove to Gao Gu that scholars who only know how to memorize books are definitely waste among wastes. A truly excellent scholar should have a lot of knowledge.

"Yeah!" Bai Minghe just said kindness and didn't stand up at all.

Yu Qian had already stood up. You should know that Wu Yu Bi was a famous official in the Ming Dynasty. Yu Qian had a high status, but as a Confucian minister, he had to give Wu Yu Bi some face. But Bai Minghe couldn't sit upright. Whether it was due to age or the reason for respecting the elderly, Bai Minghe was rude.

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

"Let's go, you will regret it for a lifetime." Bai Minghe suddenly spoke.

Wu Yubi didn't look back and asked calmly: "Are you like the left governor of Guangdong?"

"No! It's like a dead dog on the street, and it's the kind that was beaten to death because of stealing food. You should know that my white-name crane has the ability to make your reputation inaudible!"

"Shameless..." Wu Yubi was furious and turned around and pointed at Bai Minghe.

But the white-famous crane slowly lit a cigar: "Ask you a question, what factors do you think are needed to form leadership?"

"What is leadership?" Wu Yubi quickly calmed down after getting angry. He knew that he was successfully angered by Bai Minghe, but there was no need to anger himself with the rumors about Bai Minghe, let alone humiliate himself. Then he was aroused a sense of curiosity in his heart, that is, what does Bai Minghe want to do?

"Leadership, in my language, means: it means making full use of manpower and objective conditions within the scope of jurisdiction to do what is needed at the minimum cost to improve the efficiency of the entire group's work. In other words, there are many people who are willing to sacrifice their lives and have to do their best."

After listening to Bai Minghe's explanation, Wu Yubi asked without hesitation: "Is that kneeling for people to see?"

"Is Wu Qi sucking pus for soldiers to show them?" Bai Minghe also asked back.

Wu and Bi did not answer. These two things seem to be incomparable, but they are closely related.

"The sparrow and swan are a bit too much. After all, you are also a famous official. Just say it straight, please come here this time. I will use two ideas, one is to make you awaken and reflect on yourself, and then do big things. The other is to use you well. If you cannot wake up, then I will hit you hard and use the power of hitting you to accomplish my business. It is very direct."

Wu Yubi didn't respond, Gao Gu was a little unhappy, but Yu Qian pulled him aside.

Yu Qian whispered to Gao Gu: "If you keep listening, it will definitely be different!"

Wu Yubi retracted the topic just now: "Leadership, just in Nanjing City, said that when you build the Yuewang Temple, the Yuewang's heart is leadership, and with Yuewang's army indestructible."

"Leadership comes from fear, interests, and belief. If you don't explain it, explaining such details to a great scholar like you is to look down on you. But to borrow a Confucian saying: If you don't examine its origins, you will not be able to understand the changes of ancient and modern times; if you don't understand the gains and losses, you will not be able to get the path to entry."

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

"Is this statement wrong?"

"The speech is right, but such a great speech must be from a great scholar, but I, Yu Qian, have never read it." Yu Qian gave Bai Minghe an explanation. Gao Gu also said: "I have never read it, it is a famous benevolent person in the world!"

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

But he doesn't know the source either!

In history, this sentence comes from the words of the Qing Pi Xirui in "History of Confucianism". The Qing Dynasty probably wouldn't have existed in this time and space, so this sentence is likely to not appear again.

"Don't talk about this gossip..." Bai Minghe wanted to start a topic, but it couldn't. Gao Gu was a little serious: "Let's explain the source of this first?"

"I said. I am well-read about poetry and books." Bai Minghe replied in anger and smiled: "It doesn't matter whether you believe it or not, I won'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 was used to the style of Baiminghe, but he believed that this might be the theory of Baiminghe.

Wu Yubi was completely confused. Who is this? He is living faces, trees and barks, and the white cranes are unable to understand. (To be continued, please search for astronomy, novels are better, updated and faster!
