Dong Chen originally only planned to let Jade wear a women's ......

Ahem, he originally only planned to let Jade dress up as a Danjiao, and then restore the ancient art of the Earth Hua Kingdom here, just perform it on a small scale, but now he has changed his mind.

Shibel needs funds to develop the Black Rock City Truth Society, and Dong Chen also needs funds to develop his own plan, which is like a bottomless pit, so he needs to have a lot of money-making projects.

As for the bicycle factory, you should be able to get a lot of money when it is opened, but just one is not enough.

As for the manuscript that was taken by that guy Jin, Dong Chen didn't expect to make any money.

For the time being, he doesn't want to develop military equipment, which is very profitable, but it's also easy to get into trouble.

The Truth Society or other underground organizations of the Western barbarian camp are all interested in assassinating military equipment researchers, especially high-level scientific researchers, and even do not hesitate to lurk for a few years or more in order to kill an important military equipment researcher.

When the war starts again, with such a record, they will be able to reach the Western Continent and receive a reward there.

If Dong Chen started to invent weapons now, then he would definitely be harassed by many Western barbarian camp forces, and even cause damage to his environment, which he was very unwilling to see.

This will not only interfere with his progress, but also put the people around him in danger, so for the time being, let's get something that seems "harmless" to the Western barbarians.

When it comes to making money, Dong Chen, who is a Chinese, first thought of eating, and it just so happens that the Black Rock City Truth Club is located at the bottom of the True Taste Restaurant, and opposite the Black Rock City Science and Technology God Cult, which is just right.

He first provided Sheebel with a lot of recipes for new dishes, and he also gave her a lot of recipes for new spices, which he adapted to the tastes of the people here.

The "voluntary" experimenters included the barbarians they represented, and there was also a week of Terran experimental teams of all ages, that is, the caravan led by Mehya when he came out of the Terror Forest.

Then there is Xia Ya, a snack seller, she has been a "volunteer" experimenter for the longest time, and she is from the imperial capital, and she can be regarded as a master who has eaten and seen, and has provided a lot of data and suggestions for Dong Chen to adjust the taste of the formula.

After giving these things to Xibei, she can give Zhenwei Restaurant and a series of catering industries under her control a good opportunity to develop, and dominate the catering industry in Black Rock City is just around the corner.

If you can develop, you can increase your income, and when you expand in the future, or directly sell finished ingredients, all kinds of sauces, all kinds of canned food, it is a long-term way to make money.

As long as there are people who need to eat, there will be money.

This is also the reason why Dong Chen will go to Zhenwei Restaurant to eat, because the food there has indeed risen several levels, and it is already in line with his taste.

Originally, when Dong Chen was eating here, he said that he wanted to adjust the back kitchen, but he really planned to make the business here better, after all, this will be his own business in the future.

When he saw Jade at noon, he thought of another way to make money, that is, the entertainment industry.

At lunchtime, he asked Sheebel to visit his workshop in the afternoon, where he had a new invention to make money.

When Shibel came in the afternoon, he found that Dong Chen was fiddling with a strange piece of mechanical equipment, which looked quite rudimentary.

The machine looks like a makeshift patchwork of different models, with a metal barrel attached horizontally to a bracket, its surface engraved with fine threads, and connected to a small crank.

Next to the metal tube is a metal tube of the same size with no threads, and there is a needle in the center of its bottom membrane, and the needle is facing the groove of the metal cylinder, and on the other side of the metal tube is connected to a rough amplifier with a coil of iron sheets, which is the whole picture.

"So...... Boss, can this thing make money? Shibel looked at Dong Chen suspiciously.

"With all due respect, judging from the aesthetics of our elven race, this machine has no beauty at all, and it will not make people want to buy it."

Of course, Dong Chen knows that even if he doesn't look at the elves' picky aesthetics, in terms of human aesthetics, this is also an ugly guy.

So Dong Chen had no objection to Xibei's words that this thing was ugly, he just said, "Time is a little tight, so it can only be like this, although it is not good-looking, but it can basically show its effect." ”

"Its main selling point is not aesthetics, but the secondary part of knowledge, let you see the magic now."

As Dong Chen spoke, he took a neatly cut tin foil from the side, then removed the tin foil and carefully wrapped the tin foil on the cylinder, and after rolling it, he reset the tin foil, and finally looked at Xibert and smiled and started his own performance.

He shook the crank to turn the tinfoil-wrapped cylinder and said into the horn, "If I say I'm doing the magic of a sound, and I can record it and let the machine out, do you think it's going to be bought?" ”

After saying this, Dong Chen stopped shaking the crank, then closed his mouth and looked at Xibei, and his hand began to shake back.

“…… Will it be ...... to buy people under it?"

Listening to the other way around, Dong Chen noticed that he didn't reset the cylinder, and then quickly reset the cylinder to its original position, and then began to shake the crank, this time the sound was right, it was the sentence he just said.

It's just that the sound has noise, especially in the place where the tin foil is butted, and the speed of his shaking also affects the speed of the sound, for this, he is still a little dissatisfied, but this is a rough and rushed demonstration, so it is enough.

He was paying attention to his rough gramophone, completely oblivious to the surprise behind him.

If it were a modern earthling, they would be able to know that there were grooves on the metal cylinder under the tin foil, so with the ups and downs of Dong Chen's speaking voice, the stylus could carve different shades of grooves on the tin foil, and when the stylus vibrated repeatedly along the ripples, it emitted the original sound.

This is the most primitive phonograph, and it is a mechanical hand-cranked phonograph.

The main reason is that Dong Chen has nothing else here, and it is impossible for that kind of delicate gramophone to be made in such a short time.

The threaded metal cylinder comes from a metal pipe, Dong Chen sawed off the threaded part of the front section with a hacksaw, and the others are some leftovers, small iron frames, etc., and the iron horn is also found by himself to roll the iron sheet, which can be said to be extremely simple.

But it was the first time Sheebel had seen such a thing, and she was stunned that such a humble thing could do such an amazing thing.

When Dong Chen turned around and came back to look at Xibei, he realized her surprise, so he asked, "How is it, how do you feel about this machine?" ”

"I've never seen a machine like this," Hiebel said in shock, "and I'...... Can I try it? ”

"Of course."

Dong Chen happily agreed, and taught Xibel how to use it, and also gave her a new piece of tin foil, because the sawn down part of the threaded pipe is very short, and the record is not called a few words.

In this way, Dong Chen found that an elf children's song was sung quite well by Xibel.
