Huguan County. A team of real craftsmen arrived here from Lijiazhuang, and there were more than 400 people in their group, accompanied by a large number of various equipment, design drawings and so on. They were going to build a new arsenal here. This is their task.

"Thank goodness. They finally arrived here safely. I don't really know what to say if they can't get here. Ma Heng looked at the team of craftsmen and said excitedly.

"Yes, sir, they arrived at a better time. If they don't come again, we can only worry about them except for the problem, but now, all the problems are solved. A staff officer said.

"Quick, get them some hot soup and blankets. They must have frozen. These are treasures, and they can bring us a military factory, and a lot of munitions. Ma Heng said.

"Yes, sir." The staff officer immediately went safely. Ma Heng welcomed the arrival of these craftsmen, and along the way, he sent many, many troops to protect them. Fortunately, they have a strong deterrent to the nearby bandits during this period of time. Otherwise, they will cause them too much, too much trouble.

"Great. That's great. Ma Heng said excitedly. The horse is lacking too much ammunition. If there was a military factory to help them produce enough ammunition, the problem would be solved. Their predicament can be completely changed.

Artisans came from afar. They came here for one purpose, to build a new munitions factory, in which a certain amount of shares were their own, and not only that, but every worker who came here would receive more than two hundred to five hundred land bonds. Arrived in the field. There will also be land to house them, and their children will also work in such factories. That is, their children and grandchildren have a stable income. Although it is difficult to leave their homeland, there may be better development there, and they think so, and they do so, so they came.

"The IRA here obviously welcomed us warmly, and they prepared us mutton soup. When I drank the mutton soup, I felt that the cold in my whole body was completely eliminated. I never thought the world would be so good. All in all, everything here is very much in line with our set of ideas. That's the best thing to do. Craftsman Wang Xiaodou said. He was just an ordinary worker, but here they were treated the best. The houses in the county are all those big houses. This was something they had never thought of before. They were also forced to come here, but they didn't expect to get so much stuff, which surprised them.

Lijiazhuang. Shang Wu's laboratory, he still doesn't know what happened in Huguan, but Shang Wu is constantly improving his telegraph system. The backward means of communication made Shang Wu decide to invent the telegraph first.

The first is the cable. A large number of wire drawing machines appeared, allowing him to also make cables. Although radio communication is mainly an important role of diodes, he is not yet able to build such a high-tech device, but for wired communication, he can still do it. In the early days, most of the cables were wrapped in linoleum paper, and in some places they were even bare, because the current demand for communication was not very large. It can be fully battery driven. Sangwu made several batteries. Of course, the cost is also very high, a lot of sulfur, sulfur coal is burned. There is no way, in the case that the technology cannot be upgraded, he can only use this way of consuming a lot of raw materials to do such a thing.

There is an electric current. Next up was the telegraph. The telegraph is very simple, Morse code is a bit and a crossbar to complete. He became less reminded of the early telegraphs, which used turntables or even small beads. And Shang Wu used a hole punch, which was the most mature way, and Shang Wu first asked a blacksmith to make such a small machine. In addition, he found a few magnets. Those were bear children's toys, but now, they have been requisitioned as military supplies. Of course. They also got other toys of their own. Model gun. Maybe the model gun is more useful than the iron sucker**. Make use of copper wire, magnet, and then cable. Generate an electric current. Then drive the punching machine. This way, they can scroll through the translation of a few simple passwords into the communications they need most. It's primitive, it's backward. But it works.

"What are you up to?" Jia Xu was used to coming in without knocking. He liked some of Shangwu's inventions.

"Don't move. I'm inventing a machine that can quickly relay information in a short amount of time. Shang Wu said.

"Oh. Is there anything like this in this world? Jia Xu asked Shang Wu curiously.

"Yes, we are getting more and more bases. For example, I can't grasp Ma Heng's situation in time, the reports he sent were half a month ago, in order to make such adjustments, our only way is to think in advance of the situation he may encounter, if this continues, it will be very unfavorable to us. Shang Wu said.

"Indeed, we have fewer and fewer cavalry. The supplement is also insufficient. If this continues, our communications will be extremely bad. Jia Xu said helplessly. The situation in the base area is not optimistic, for example, the most important point should be said is their communication situation, the communication of this era mainly depends on the rapid running of horses to achieve, the delivery of a message, may take a long time, such as Lijiazhuang to Huguan, the straight-line distance is only more than 200 kilometers, this is Shangwu's estimate. But that's the distance. It would take them seven days, the fastest of which was five, but it can be estimated that their time will become longer and longer, because they do not have enough horses for such a task, and there are less than a thousand horses in the whole army. A lot of important messages can't be delivered in time because they need to be accumulated before they can be sent out in one piece. In the information age, a piece of information will be worth millions, possibly more, and in this era, the severity of military communications will become even more serious, because there is not much information in the first place, and there will be many delays. It's for them. It doesn't get any worse than that.

"This machine of yours. What do you think? Jia Xu asked curiously.

"I'm doing experiments, you see." Shang Wu started the machine that had just been adjusted. Shang Wu then kept tapping on the small metal plate, and the current was invisibly cut off one by one. On the other side, Jia Xu looked at Shangwu's gadget in surprise. The punch keeps punching small round holes. Many people can come up with such a small invention, but how to use it. Only a monster like Shangwu can come up with it.

"Da-da-da-da. Da-da-da. As Shang Wu stopped tapping, the punch stopped working, and a series of small round holes appeared on it, but they were irregular, but they looked very neat.

"What is this?" Jia Xu asked Shangwu in confusion. He looked at the notes with small holes, and although Shang Wu had operated such a hole punch in another section and looked very angry, Shang Wu noticed. There's a wire connected to it. The secret is in what the martial arts call electricity. However, he didn't know how Shangwu controlled them.

"You see, these little holes are very regular. Here is a space, where there are small holes, it is a dot, and where there are no small holes, it is a horizontal bar. Four in a group, they form a number, for example, this one I typed is a set of numbers. Three. It's three dots and one kong. Two. It's two points, two bars. Shang Wu compared it to Jia Xu.

"You see, in this case, a password is formed, and he probably means, three-two-one." Shang Wu said.

"If we use communication, as long as the other person knows a book, I know a book, and then we send the page number, the number of lines, the first few digits, and we activate the numbers, we can complete the communication. However, this requires communication and relay. It may be that our cables still need to be laid for a long, long distance. Shang Wu said with a smile.

"In other words, this machine of yours, we send it here, and the other side can receive it immediately. It can be accepted from hundreds of miles away. See. And at the same time? Jia Xu asked Shangwu. It seems that Jia Xu is very excited.

"Hmm. Theoretically, it should be. Shang Wu said.

"Oh my God. I don't know how you have the brains to come up with something like this. That's a lot faster than horses, and if the various commands had such machines, oh my God. I can't believe it. Jia Xu looked at the telegraph system excitedly and said. He was excited. He felt that he had found the best way to communicate in the world. Jia Xu was naturally surprised.

"I think it's the best invention out there." Jia Xu looked at the telegraph system excitedly.

"Hmm. But this is a laboratory thing, and if we want to popularize it on a large scale, we need to conduct a series of experiments. You know that. Such things need to be laid out in time. Shang Wu said. But the problem is that he still lacks something necessary, and that is electricity. The telegraph could only be driven by batteries. In this way, the problem of electricity becomes prominent, he can't know so many batteries, right? And the battery is a consumable. Because he didn't have a generator yet, charging couldn't be done.
