The Weapon Tycoon Who Traveled to Great Qin

As it enters autumn, it gets darker and earlier. There is no use for the sunglasses just made. No one would wear sunglasses on the street in the dark.

"It's all you. You idiot. It's all you. Why didn't you finish it earlier. It's all dark. The sun is down." Yingyu said while looking at the setting sun.

"Then I can't help it. I can't hold the sun to prevent him from going down the mountain. He is that big." Shang Wen said helplessly.

"Oh! I thought of going there in the palace. Now. It's boring." Yingyu finished speaking and got on the bus. The two came in joy, and returned in defeat. But Shang Wen seems to have thought of an important thing. That is the telegraph machine. Shang Wen originally planned to invent the camera. But when I was doing some solution experiments, I felt that the timing of the telegraph was a bit ripe.

Battery, copper wire. Plus an electromagnetic sensor. Such a device only needs to be modified slightly. These conditions Shangwen suddenly felt a lot more mature.

The electromagnetic induction phenomenon has been done before. For example, the generator experiment is a typical electromagnetic induction phenomenon. However, Shang Wen himself did not elaborate too much in theory. But this does not mean that this phenomenon does not exist. No one found out.

"Pa" Yingyu saw Shang Wen thinking about things. He slapped Shang Wen's head with a palm of his hand. It's mainly because of some anger in my heart. I blame this nerd for his slowness.

"Oh!" Shang Wen screamed.

"Why hit me". Shang Wen called.

"It's all bad for you. Slowly. It's really anxious." Yingyu said.

"Is there still tomorrow?" Shang Wen said.

"Tomorrow, tomorrow. I can't wait anymore." Yingyu said.

"Do you know what I just thought?" Shang Wen said.

"What?" Yingyu asked.

"I'm thinking about the telegram. The telegram...". Shangwen hasn't finished speaking yet. Yingyu began to mutter.

"Telegram? Can the telegram be reported?" Yingyu asked. Yingyu knew about the existence of batteries. Also know what the electric looks like. She has been watching Shangwen doing strange experiments. The resulting electric spark Yingyu considers it to be electricity. It's still numb and painful. In her knowledge. Electricity is dangerous. Women's intuition is so sensitive. Shangwen is not yet in danger of popularizing electricity. Yingyu already knew.

"The telegraph is to transmit messages. I want to invent a machine composed of electricity and horizontal lines. Then, according to the transmission of these machines, it is enough to receive these signals. Isn't your train very slow? With the telegraph, it is very fast. It has arrived." Shangwen explained.

"Faster than a train?" Yingyu asked.

Shang Wen nodded.

"Yeah. Okay, I believe it. But I went back to the palace. I will see tomorrow morning. Do it yourself slowly!" Yingyu got off the car after speaking. The carriage has returned to Shangwen's office.

"Hurry up!" Yingyu urged after getting out of the car and turning around.

Shang Wen shrugged helplessly. One of his arms is still injured. Can it be fast? But it is also hurt. Many things are left to others. Such as document approval. Meng Yi took the overwhelming majority. In this way, Shang Wen is free a lot. Otherwise, he would never have time to do so many experiments.

Shangwen soon began to make telegrams. In fact, the telegraph made by Shangwen is a Morse telegraph, not a twenty-six key, a magnetic needle telegraph, and a five-pin telegraph that appeared before this telegraph. The principle of these telegraphs is simple. They all use electromagnetic induction. But his operability is very poor. Or not suitable for current requirements. such as. Twenty-six keys. The electromagnetic induction phenomenon is used to attract the small pieces of paper with letters written on the bottom with a small energized copper ball. This accuracy is very poor. And regardless of the pointers behind, the system established by five needles is based on twenty-six letters. Instead of the simplified code consisting of dots and horizontal lines later. This code can represent numbers. letter. Punctuation and so on. There are tens of thousands of Chinese characters. It can be simplified to represent with numbers.

Shang Wen jumped directly over a long distance of invention. Morse built a telegraph machine. Its sending device is very simple, is composed of electric keys and a set of batteries. Press the power button, and current will flow. Pressing for a short time indicates a point signal, and pressing for a longer time indicates a horizontal line signal. Its ticker device is more complicated and consists of an electromagnet and related accessories. When an electric current passes through, the electromagnet generates magnetism, so that the pen controlled by the electromagnet also records dots or horizontal lines on the paper. The effective working distance of this transmitter is 500 meters. This is the telegraph machine that Shangwen is going to do.

But it will cost a lot of money to be popularized on a large scale. The price of natural resin is definitely not cheap. The quantity is very scarce. And because of the geographical location. The latitudes are all above twenty. There is no subtropical, tropical climate area. No rubber at all. Can think of. The insulating material imposes too much electrical restriction on Qin State. Those scholars from the State of Qin who study electricity need to spend a lot of money to have insulated wires tens of feet wide.

"Call" on it. Shang Wen exhaled heavily. Shang Wen built a telegraph in the shape of a historical museum. Shang Wen watched for a while. It was already more than two o'clock in the middle of the night. Shangwen stayed up again to complete a new invention. But this invention is very worthwhile.

The appearance of the telegram. Let the world become small all at once. Information transmission has become extremely convenient. think about it. The train is getting bigger and bigger. The departure is getting faster and faster. Telegram can send messages from thousands of miles away in a short time by pressing the button. This is definitely a big advantage in the military.

The other party just dispatched. We know by telegram. The top level also knows. Via telegram. King Qin could convey the news to the commander on the front line as quickly as possible. Think of this as an advantage. However, insulated wires have become a problem. His price can be compared with gold. But it's not impossible. The use of coal will provide Shangwen with new insulating materials. There is no coal. There is also oil. The potential of these two industrial raw materials is huge.

The reason why Shangwen invented the telegraph may be subconsciously. The trigger may come from earthquakes in the region. The speed of information dissemination has caused many people to die because of untimely rescue. This makes Shang Wen hang in his heart. The telegram is also in the process of experimentation. Had a hazy feeling. But it's all right now. The telegram finally came out.

Because of the telegram. Shang Wen was very excited. He decided to work harder. The camera was also invented. Give Yingyu a big surprise. Things are all imagined. Some silver halide was not used in the morning. Shangwen decided to do more. Because there is also a large amount of silver halide that is needed to develop photos. And also temporarily remodel the room as a darkroom for developing photos.
