"It's over." Shang Wen said.

"Bring it, how about your camera?" Saying that, Yingyu was about to step forward and get the photo.

"Wait!" Shang Wen shouted.

"Now it's on the negative, and I'm going to have to develop it for a while. Once exposed. I can't wash it if I want to. Shang Wen used his hand to stop Yingyu from moving forward.

"What? Still need to wash, photos still need to wash? Yingyu couldn't believe her ears. Photography also requires washing.

"Forget it, I'm happy today, I'll wash it for you." Yingyu said that she was about to step forward.

"Wait. That's not going to work. This one can't see the light. Once you see the light, it's bad. Shang Wen said.

"Wash things, of course you have to see the light." Yingyu said that she was about to approach Shangwen.

"Wait a minute. This photo development is a chemical process. Print the scene on the photographic paper. If it breaks. I can't do it if I want to. Shang Wen said anxiously.

"Chemistry. You got it. When will I be able to see the photos? Yingyu asked.

"At the very least, I'll have to adjust some chemicals and make some photographic paper. At the very least, it will take an hour and a half. It also takes some time to dry. At the very least, you'll have to give me three hours. Shang Wen said.

"It's too long. For such a long time, the paintings were all done. You're a big liar. Yingyu was dissatisfied with the effect of the photo not being able to be seen immediately.

"Yu'er, don't be rude." King Qin stepped forward to help Shang Wen relieve the siege.

"Sir, don't care. The widow believes that this time can wait. Sir, you can do this telegram thing first. "King Qin doesn't care how the photo is. Since the photo takes a certain amount of time, it is okay to wait a little. But the telegram thing can't wait too long. Because of the speed of spreading the news, King Qin was also very dissatisfied. Now, all of a sudden, there is a machine that can deliver information. How did King Qin Wulu actually see with his own eyes how effective it was.

"I'll do it." Shang Wen said and packed up his camera and left. Especially the negatives. Shang Wen put it into the house. Specially placed in a makeshift darkroom.

"Zhao Gao, go and invite Wei Yi, Wang Jian and others to come. The widow wants them to see this miracle happen with the widow!" King Qin said.

"Whoa." As he spoke, Zhao Gao left quickly. Shangwen, on the other hand, was busy making a second transmitter. At the same time, he also called an attendant of the King of Qin and told him to teach him how to operate. A person clearly does not understand how to operate. The attendants are not stupid, they will teach them.

I heard that King Qin had invited everyone. Shangwen decided to demonstrate it within his own feasible range. He had the telegraph line stretched to the limit, and at the limit, another telegraph machine was set up.

Shang Wen's actions immediately attracted onlookers from passers-by, and reporters also heard the news and joined the crowd of onlookers. But when they heard that King Qin was here, they all knew that something big was going to happen. At this time, the military generals of the Qin State began to arrive one after another. They had seen King Qin one by one. And Shang Wen was so busy laying telegraph lines and other affairs that he didn't have time to communicate with them.

"What does this Mr. Qin have to show?" Wang Jian asked Wei Yi.

"How do I know, I also just arrived, but I heard from the CRRC government order (Zhao Gao's official position) that he invented a kind of kung fu that can spread the letter within the blink of an eye to thousands of miles, thousands of miles away." Wei Yu said.

"What? What did you say? Wang Jian asked with some excitement.

"What?" Wei Yi looked at Wang Qian, but then understood what Wang Jian meant. Then he said again.

"I remember. The CRRC government decreed to me, it seems to be called a telegram. In the blink of an eye, a message can be sent thousands of miles away. Wei Yu said.

"Oh." Wang Jian nodded. The news was a shock to him. The battlefield changes very quickly, especially the speed at which information is transmitted. Whoever learns the information about the enemy situation first will have the initiative. Wang Jian is very clear about this.

"Alright. Let's go. When Shang Wen laid out the line, he thought that the Qin State should build a power plant. In this way, electricity can be popularized, and telephones, electric lights, etc. can enter thousands of households.

However, Shang Wen thought that he must give priority to the development of telephones in the future. This eliminates the need for the hassle of tapping the telegram with your hands. As he spoke, Shang Wen began to "tick and tick" the buttons. King Qin, civil and military officials, and some reporters and civilians watched Shang Wen's performance together.

Shang Wen arranged the symbols of a few words in advance. Then start the experiment. Shang Wen tapped the telegram for a while, and then stopped. Then, Shang Wen's receiver began to work, and the receiver's pen began to draw dots and horizontal lines on the paper. These dots are divided into groups of five, with blank spaces in between. The telegraph Shangwen has a small note. This was made specifically for Telegram.

The telegram was still being accepted, but everyone didn't know how Shang Wen made the machine move. After turning for a while, the receiver stopped working, and Shang Wen took out a pencil and began to compare it with the pre-made codebook. The content is only four words: "Long live Great Qin." "The payment is received by the prime minister.

Shang Wen took the translated slip of paper and the code book and presented it to the King of Qin.

After seeing this, King Qin shouted loudly, "Okay." "And then hand it over to everybody to see.

"Mr. Qin, where is this person who sent the report?" King Qin asked.

"Your Majesty, the messenger is a mile away. It can be longer if needed. Shang Wen said.

"Oh, look at it." As he spoke, King Qin took the telescope handed over. Look at the squire who was a mile away.

King Qin nodded after looking at it. "Farther away, is this telegram okay?" King Qin asked.

"Absolutely." Shang Wen replied.

"Okay, this telegram, the widow will cover all the territory of the widow." King Qin shouted loudly.

"My king is wise." Several officials who had read the telegram said immediately.

King Qin nodded.

"What does General Wang think?" King Qin asked, Wang Qian.

"Chen thinks that my Daqin has a telegram, which is really a great help. The drama of my Great Qin's current territorial expansion has far exceeded the territory of several generations of previous kings. How to control it has always been a problem for ministers. Now there is this telegram. The minister was very relieved. "Wang Jian has been worried about transmitting information from such a distance. But now the advent of the telegram has given Wang Jian hope. The speed of transmission of the telegraph is incomparable to that of any means of transportation, especially the speed, which allows Wang Jian to see that the future combat mode of the Qin State will benefit from the emergence of the telegraph.

At this time, the onlookers and the public, after Zhao Guo's explanation, knew that they had invented a machine that could spread the news thousands of miles at once. All the people shouted for a miracle.
