"Don't bother looking at this. There is also a small invention. Shang Wu said to Jia Xu with a smile.

"Oh? What is it? I knew you must have some earth-shattering invention. Jia Xu said excitedly.

"Here you go." Shang Wu said and took Jia Xu to another laboratory, and Shang Wu found that his experimental projects became more and more numerous. In such a situation, he naturally has more things to do. But it wasn't much of a problem to him. Because most of these inventions were successful and suitable for historical development.

"It is. A big horn? Jia Xu asked Shangwu.

"Yes, you can call it that. But I call it a gramophone. Shang Wu said.

"Gramophone?" Jia Xu asked.

"Yes. It's about keeping your voice alive. Then you can play it repeatedly, and then you will have a lot of trouble left. Shang Wu said.

"This?" Jia Xu looked at Shang Wu. He felt a little unconvinced, you look at this. Shang Wu said, holding a piece of tin foil.

"I'll plug in from here, and you'll be able to hear what you want to hear." Shang Wu said.

"Mary •••••• sheep." Shang Wu rubbed the past and said.

"What is this?" Jia Xu asked puzzled. For he did not speak, and the sound of the loudspeaker came from the tin chaff. That is, the sound is of tin foil. Although in terms of timbre, this is a sound unique to Shangwu, it is definitely not produced by Shangwu.

"This is it. You listen slowly. Shang Wu said.

"Mary has a little sheep." Shang Wu rhythmically releases tin foil strips.

"It's amazing. How do you do it. This thing can make your voice heard. Jia Xu looked left and right. He thought it was amazing.

"Vibration, you can touch your throat, you can see that in such a situation, you can solve such a thing at once. This kind of thing for you. It's very advantageous. In such a situation, most things can actually be done. Shang Wu said.

"Shock?" Jia Xu began to tentatively touch his throat and nodded.

"You can see that this tin foil is uneven. through a contact head. Then the vibration causes the vibration of a piece of metal film paper, and then the vibration expands and expands, and then you hear this sound. Shang Wu said.

"Hmm. It sounds simple, and it's real. Jia Xu said.

"Hmm. So, a lot of things exist that we haven't discovered yet. Jia Xu said.

"Of course. There's many, many more, but it's all in the lab. If we want to have more inventions, we must encourage more people to make such inventions. This is the importance of enlightening the people. Shang Wu said.

"Can they really invent these things?" Jia Xu asked Shangwu with some uncertainty.

"If we can encourage them to do this, they will definitely be able to do this, but we also need an exemplary role, that is, to expand the set of military factories to the civilian sector, to more and more areas, so that many things can be promoted." Shang Wu said.

"Hmm. I agree with you to do so. Jia Xu agreed.

Just when Shang Wu and Jia Xu were discussing the specific details of encouragement. An invention in a garment factory caught the attention of the factory manager, as well as more workers.

"Da-da-da-da-da." With a woman turning the wooden wheel. Some of the early sewing machines using metal objects appeared on the workshops of garment factories. The workshop is actually a larger room. There were more than twenty-two people working inside. There is a charcoal basin at the door. You have to leave it there, because it's all fabric, and if it catches fire, it's very troublesome. This must also be watched by a special person, usually a female worker.

"Su Niang, is this something you invented?" The director looked at this early sewing machine. The principle of a sewing machine is simple. It's a thread that goes through, a lead that thread. If they sew clothes regularly, they will carry out a series of operations according to their manual work.

"Yes, because the daily workload is too much. Too big. My husband was still a carpenter, and he saw that I was tired and discussed with me. I made such a machine, this machine, it's okay, the sewing is stronger, but it can't be knotted. The speed is not well controlled, and you have to be proficient to use it. Otherwise, something will go wrong. A woman named Su Niang explained. But there are women all around, and they feel very comfortable with such machines. At the very least, much faster than they can sew by hand. Garment factories have too many orders. Too much. As a result, they have to do a lot of production every day, and they often have to stay up late to do it. This made Su Niang, a young couple who had just gotten married, very dissatisfied. So his husband, as a carpenter, began to work on his own head, whether he could relieve such a burden. After all, they make fifty of these ready-to-wear garments a day. This kind of work is quite tiring and is all done by hand. Those who are skilled may be able to do it, but those who are not skilled can do one or two things well.

Sewing machines are in great demand because they have too many production tasks. With such a heavy task, it is natural that such a thing is needed to solve such a problem as theirs. Obviously this is one of the best products.

The principle of this sewing machine is the same as that of today's sewing machines. But this sewing machine looks very rough. It's so rough that you think it can fall apart and it won't work. But it was such a sewing machine, which was of great significance, because it meant that the factory officially became a factory, because they began to use machinery as a new tool of labor. In this way, the value they generate will also become great.

Most sewing machines are made of woodwork, because of the special properties of carpenters, except for a few ironware, most of them are made of wood. Make it bigger, do it uglierly. But it is impossible to deny the significance of his appearance.

"It's definitely a great invention. In this way, let's quickly invite some carpenters to come over. Hit a few like this. In addition, I want to report this matter to the above and reward Su Niang's invention. If it's good, we can all use such a machine in the future. The director said. Everyone was very excited, after all, such a thing is very important to them, with a sewing machine, they can easily complete the workload of a day, or even more than a day's workload, and relatively speaking, their work is not very complicated, in this case, their situation will become extremely favorable. This is the most advantageous situation for them.

Outside the garment factory. Textile mills were also actively inventing, and women workers improved their looms with the advice of some carpenters, as well as their own. They started using a small-scale improvement like the shuttle to increase their own production. However, there are still some limitations to such improvements. But inventions and creations are already underway, which is important for the economic development of the entire base area. It is a small progress, and it is under such small progress that the entire base area continues to evolve and develop.

In Handan City, because there is no city wall, the road can be built larger. Because of the demolition of the city wall, people feel that the whole city seems to be much more empty, and it doesn't feel so aggrieved. Of course. They also find it difficult to guarantee a sense of security.

"Uncle. Doesn't this Handan city have a city wall? A teenager asked his second uncle. The second uncle is a businessman, and he has to go south and north every day to do things. Naturally, he went to a lot of places.

"Yes. Demolished. The second uncle replied.

"But the wall was torn down. What should I do if this official army comes over? These red turban soldiers, aren't they afraid? The child asked.

"Silly boy. You didn't notice. When you were in the wilderness, didn't you see some people walking on the high ground? That one has cannons on it. The officers and soldiers were discovered before they could be dispatched. And you can't get close to here because there's a cannon outside. Only a few cannons can stop tens of thousands of officers and soldiers, this Handan city has no city walls, but it is more powerful than having a city wall. The second uncle said. The kid was surprised. He really hadn't noticed anything like that.

"Let's go. There are a lot of things here that are different from us. We've got to see, get something back, and then we can do anything. The second uncle said.

The child nodded blankly. A lot of things here are different.

"Second uncle, what is that for? It seems like a lot of people. The child asked, puzzled.

"Hmm. I don't know. Let's take a look. The second uncle took the child over to see the situation, and they didn't know what it was.

"Hey. Big brother, what's written on this? Although the second uncle knows a few words, if he wants to know all the words, he can't do it. So the only way is to ask.

"Oh. You're from outside. This is our local securities trading center, where you can spend money to buy bonds, stocks and other investment financial products. If you want to sell, you can sell it here. Anyway, this is the place to make deals. A local explained.

"Oh. I see. This is similar to dental rowing. The second uncle said.

You can understand it that way, too. However, the fair trade here is reasonable for the fee. And. Most businesses can buy it here. Very cost-effective. There are also military-industrial stocks in it, which you can check out. Locals introduced.
