The weapon tycoon who traveled to Daqin

As the autumn is getting dark, it is getting earlier and earlier. The sunglasses that have just been done are not available. No one will wear sunglasses on the street in the night.

"It's all you. You are a nerd. It's all you. Why don't you finish it earlier. The sky is dark. The sun is going down the mountain." Yu Yu looked at the falling sun.

"Then I can't. I can't grab the sun to prevent him from going down the mountain. He is so big." Shang Wen said helplessly.

"Oh! I thought about going there in the palace. Now. It's boring." Yu Yu said in the car. The two came to have a prosperity and returned. However, Shang Wen seemed to think of an important thing. That is the telegram machine.

Shang Wen originally planned to invent a camera. However, when doing some solution experiments, he felt that the timing of the telegram was a bit mature.

Battery, copper wire. Coupled with electromagnetic sensors. Such devices can only be modified slightly. These conditions Suddenly, Shang Wen suddenly feels a lot of mature.

The electromagnetic induction phenomenon has been done before. For example, the experiment of the generator is a typical electromagnetic induction phenomenon. However, Shang Wen himself did not explain too much in theory.

People go to discover.

"Papa" Yuyu saw Shang Wen thinking about things. She slammed on Shang Wen's head with one hand. It was mainly angry in her heart. Blame this nerd slowly.

"Oh!" Shang Wen screamed.

"Why hit me". Shang Wen called.

"It's not good for you. Slowly and slowly. It's so anxious." Said Yu Yu.

"Isn't there any tomorrow?" Shang Wen said.

"Tomorrow, tomorrow. I can't wait." Yu Yu said.

"What do you know what I thought?" Shang Wen said.

"What?" Yu Yu asked.

"I'm thinking about the telegram. The telegram ..." The Shang Wen said before it was finished. Yu Yu began to mutter.

"Telegraph? Electric can also make reports?" Yu Yu asked. Yu Yu knew the existence of the battery. She also knew what the electric length was like. She has been watching Shangwen to do strange experiments.

. It was also very numb and painful. In her knowledge, electricity is dangerous. Women's intuition is so sensitive. Shang Wen has not yet popularized the danger of electricity.

"The telegram is transmitted. I want to invent a kind of electricity, the machine composed of horizontal lines. Then transmit it according to these machines, accept these signals. Isn't your train departing slowly? With the telegram speed is very fast, it is very fast.

It was passed to. "Shang Wen explained.

"Faster than the train?" Yu Yu asked.

Shang Wen nodded.

"Well. Okay, I believe it. But I went back to the palace. I will see it tomorrow morning. You can do it slowly!" After finishing talking, I got off the car. The carriage had returned to the place where Shangwen office.

"You hurry up!" Yu Yu turned around and urged.

Shang Wen's helpless shrugging shoulders. There is still injuries in his own arm. Can you be fast? But there are any injuries. Many things are given to others to do it. For example, the file is approved. Meng Yi assumes the vast majority.

A lot of free. Otherwise, he definitely has no time to do so much experiment.

Shangwen soon started to make a telegram. In fact, the telegram made by Shang Wen is the 26 -key, magnetic needle telegraph machine, and five -needle telegraph machines that Moos teleb not appeared before this telegram machine.

. They use electromagnetic induction. But his operability is very poor. Or it is not suitable for the current requirements. For example, the twenty -six keys. Use the electromagnetic induction phenomenon to use the small copper ball to adsorb the small paper below

This accuracy is very poor. And no matter whether it is the subsequent pointer, the system established by the five stitches is based on 26 letters. Instead of the code composed of later simplified points and horizontal lines. This code can represent numbers.

Letter. Punishment symbols, etc. There are tens of thousands of text in China. Use numbers can just simplify.

Shangwen jumped directly to a large number of invention distances. Momes created a telegram machine. Its reporting device is very simple. It is composed of electric bonds and a set of batteries. Press the electric key, and the current passes.

The short -term promotion of the point signal is expressed, and the long time indicates the horizontal signal. Its receiver device is more complicated, which is composed of an electromagnet and related attachments.

In this way, the pen -controlled pen is also recorded on the paper or horizontal line. The effective working distance of this reporting machine is 500 meters. This is the telegram to make by Shangwen.

However, it takes a lot of money to popularize a large scale. The price of natural resin is absolutely not cheap. The quantity is very scarce. And because the geographical location, latitude are more than 20 or more.

No. You can think of it. The insulation material is too large to the Qin Dynasty's electrical science. Those scholars who study electrical science need to spend heavy money to have dozens of insulating wires.

"Huh" just. Shang Wen exhaled heavily. Shang Wen created a telegram according to the appearance of the historical museum. Shang Wen read it for a while. At this time, it was already at two o'clock in the middle of the night. Shang Wen stayed up late to complete the new invention again.

However, this invention is very worth it.

The appearance of the telegram. The world suddenly becomes very small. The information transmission becomes extremely convenient. Think about it. The more and more the train is.

It is passed over. This is definitely a major advantage in military.

The other party just dispatched. We know through the telegram. The highest level also knows. Through the telegram. Qin Wang can convey the news to the commander of the front line at the fastest speed. Think about this is an advantage.

. His price can be compared with gold. But there is no way. The use of coal will provide new insulation materials for Shangwen. There is no coal. There is also oil. The potential of these two major industrial raw materials is very huge.

The reason why Shang Wen invented the telegram may be in the subconscious. The inducement may come from the earthquake. The speed of information caused many people to die because of the inadequate rescue. This made Shang Wen hang in his heart.

The hazy feeling. But now it's fine. The telegram finally came out.

Because of the telegram, Shang Wen was very excited. He decided to work harder. Invented the camera. Give a big surprise to Yuyu. Things are all wanted. In the morning

. Because there is also a rinse photo also requires a lot of silver, and it also needs to temporarily transform the room as a dark room for rinse photos.
