Chapter 549 Myopia Can Be Treated with a Thermos Bottle

When Li Yi lamented that the intelligence personnel were not professional enough, Yu Huaide and a group of people carried boxes and mysteriously entered every house.

All they can find are those with relatively high net worth, and at least both parties must know each other.

Entering a house and staying there for about a quarter of an hour, they were escorted to the front door when they came out.

Judging from the expressions on both sides, they were very happy.

The person following him couldn't figure out what was going on.

Until one family delivered it and said, "That mirror is really useful. It will take three days, right? I'll wait. No rush, no rush."

"Yes, three days. It's early for you, and if others try again, you have to continue to the back." This person, Yu Huaide, was in charge.

The stalker got one word, mirror.

Selling mirrors? Do you need help selling mirrors? Everyone knows that Lijiazhuang has a mirror.

It's called a glass mirror, it's easy to clean and lightweight.

Yu Huaide and the others are indeed selling mirrors, glasses, myopia glasses and flower glasses.

People who suffer from myopia are usually scholars. Myopia is more common in wealthy people who can afford to light oil lamps and candles.

If you can't adapt to that kind of light for a long time, you won't be nearsighted.

Dyeing eyes are more likely to occur with age.

Yu Huaide and the others first found a wealthy person to sell them to. There were lenses of various powers in the box. They tried them one by one. The left and right eyes may not be the same.

After you try it and write it down, they will give you money after the glasses are made and delivered to your door.

One lens is ten pieces, and the frame is given free of charge.

If you sell one, Yu Huaide and the others will get a commission.

Don't worry about people who don't have money, otherwise it will be cheaper, how can you make money from rich people.

"Brother Yi, are you selling the glass?" Li Chengqi came over at noon. After knowing the situation, he wanted to ask.

"Scholars are short-sighted. Being an official is hard work and affects their lives. Now that we can make it, let them use it.

In a few days, I will think about how to work on the frames, make them more beautiful, and sell them at a higher price.

Ordinary ones are cheap, and people with short-sightedness and vision problems can wear them if they pay a little money. "

Li Yi discovered that when there were 220 students in class, some students just couldn't see the writing on the blackboard. They put it in the first row and still couldn't see it.

Then I thought about the troubles of other scholars. The elderly are so dazzled that they are almost as blind as the blind.

"Don't two lenses form a telescope?" Li Chengqi tested it and it can be magnified.

"It's upside down, and what can you see with that kind of telescope? The lens is thin. Have you ever dismantled the telescope? It's different, right?"

Li Yi felt that he wanted to use flower glasses to assemble a telescope, but the effect was too poor.

"You are always willing to give cheap things that make money to the people." Li Chengqi said with emotion.

"In a few days, I will burn a tea set specially. The set will be similar to the one for you, Third Brother and the others. I will publicize it in the newspaper."

Li Yi gestured like making Kung Fu tea.

He wants to sell a batch of tea sets first, and then drinking Kung Fu tea becomes popular, so that tea sales will increase.

Of course, you can drink Kung Fu tea not only with green tea, but also with black tea.

As he spoke, Li Yi took out a teapot and two tea bowls, opened the tea can, took out some tea leaves and put them into the teapot.

Then he picked up something made of bamboo from the side, opened the stopper, and poured hot water into the teapot from inside.

"Brother Yi, what is this?" Li Chengqi saw that the water was still steaming and looked at Li Yi's things.

"A thermos bottle is blown from glass and placed in a mold. When there is air in the middle, the inside is blown and the outside expands.

Leave a hole in the back and paint the inside with silver like you would a mirror.

Just like making a light bulb, vacuum it and heat the remaining opening.

The kettle bladder made in this way can be kept warm. If you add a stopper, a pot of boiling water will still be hot after being left for a few hours. "

Li Yi said how to make the pot bladder, using the techniques of glass blowing, mirror making and light bulb making.

"Do you want to sell this thing?" Li Chengqi actually understood it. The process was simple, but in fact he couldn't do it.

"Sell it as a treasure. Two hundred pieces each, free replacement and maintenance, that is..." Li Yi said that he wanted high-priced services.

If it breaks, put the pieces together and take it to Zhuangzi, who will give you a new one.

If there is scale inside, take it to Zhuangzi and Zhuangzi will clean it out.

If the thermos stopper doesn't work anymore, go to Zhuangzi directly and ask for it instead of taking the original one.

For two hundred thousand dollars, you can enjoy this service. If you break it if you are unhappy, it will be replaced by you.

"You should be like this without lights, one in a hundred." Li Chengqi thought of something else.

"Yes, it will be said in the newspaper tomorrow. It is so expensive. What should I do if the glass breaks? Replace it." Li Yi followed suit.

"How many thermos bottles do you have now? I'll take them away and deliver them to His Majesty. I also want some at home to help you promote them."

Li Chengqi was not polite at all. He knew that the cost was very low, but he would not resell it.

"It has only been two days of work and everyone is still getting familiar with it. There are only 160 qualified people and more than 2,000 scraps."

When Li Yi talked about the difficulty of production, he shrugged.

In the mold, the inner bladder is blown against the outer bladder, and if it is not controlled well, they will stick together.

When vacuuming, the heat seal is also easy to leak from the side, causing it to explode with a bang.

"Okay, I've got one hundred and sixty, so I need to handle them with care." Li Chengqi didn't care how many were broken.

The craftsmen can gradually become more proficient, and it happens to be convenient to use in winter. Otherwise, someone would have to be there to watch the fire and be responsible for hot water.

In the afternoon, he sent someone to carry it with him. He padded it with straw and couldn't touch it, especially the mouth of the pot.

I took away a thousand stoppers and filled them with water to try the stoppers.

Carrying a thermos filled with hot soup in his hand, he entered the palace and went straight to Baifu Hall.

In less than a quarter of an hour, Queen Wang arrived with her child in her arms. After waiting for a while, Li Longji arrived.

Li Longji got the news that King Song should have come from Lijiazhuangzi and brought a lot of things.

When he arrived, the palace maid was carefully pouring boiling water into several thermos bottles.

Soak the stopper in water. After pouring the boiling water, put the stopper on.

"Third brother is here. Let me show you this. It's been an hour and a half since I drank the hot soup in Zhuangzi at noon."

Li Chengqi asked people to fetch five bowls. He pulled out the stoppers and poured soup from inside.

The soup is steaming when poured out.

"It's mushroom, fungus, egg and sleeve soup, as well as diced lean meat and carrots."

The focus of Queen Wang is so different.

Li Longji reached out to touch the bowl and blew into the soup again, the hot breath hitting his face.

"It's hot. I've been pretending for an hour and a half, but it's still so hot."

Li Longji said and started blowing, UU reading www.uukanshu.net, put his mouth to the edge of the bowl and sucked it, turned his head and spit it on the ground, it was hot.

The palace maid hurried over and wiped it with a rag, and the clever eunuch ran to get the spoon.

The spoons were taken and boiled with hot water, and everyone scooped out the soup and drank it.

"The soup at uncle's place is better than the one in the palace. If you want to drink soup in the future, just get it from Lijiazhuangzi."

Queen Wang discovered the correct use of the thermos flask, filling it with soup.

"The ladies and eunuchs in the palace don't have to look at the hot water anymore." Concubine Doulu was thinking of the people who were working.

"Yes, I need to prepare a few more in my palace, but you still have to check whether it is too hot. They will also heat things to eat and keep warm. Right, Huo'er?"

Queen Wang turned to ask her son.

"Ah, ah." The little guy stared at the soup bowl, as if I wanted to drink it too.
