When Li Yi lamented that the intelligence personnel were not professional enough, Yu Huaide and his group of people secretly brought boxes to each family's home.

All they can find are those with a lot of wealth, at least both sides should know each other.

When they entered a family, they stayed for about a quarter of an hour. When they came out, they kept delivering it to the gate.

I was very happy to see the expressions of both parties.

The person who followed him couldn't even think about what was going on.

Until a family gave it to me, he spoke: "That mirror is so easy to use, three days, right? I'll wait a moment, no hurry, no hurry."

"Yes, three days, you're early, if someone else tries again, you have to continue to line up back." Yu Huaide of this household was responsible.

The person who followed got a word, mirror.

Selling mirrors? Do you need help from selling mirrors? You know that there are mirrors in Lijiazhuang.

It is called a glass mirror, easy to wipe and lightweight.

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

Generally speaking, scholars are born in the world. Rich people have more myopia, so they can light oil lamps and candles.

If you are unable to adapt to that kind of light for a long time, you will not be myopic.

It is easier to get the blind eye as you grow older.

Yu Huaide and the others first went to rich people to sell them. The boxes contained lenses of various degrees. They tried them one by one, but the left and right eyes might not be the same.

After trying it, write it down, wait until the glasses are made and delivered to the door, and they will give it to the money.

One lens is ten, and the frame is free.

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

People who have no money don’t care about it, otherwise they will be cheaper and how can they make money from rich people?

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

"Scholars are myopic and have difficulty becoming an official, which also affects their lives. Since they can be made, they will use it.

After a few days, I think about how to work hard on frames, and sell more beautiful frames for higher prices.

Ordinary ones can be cheap, and those with myopia and vision can wear it after paying some money."

Li Yi found that when 220 students were in class, some of them couldn’t see the blackboard, and they were placed in the first row, but they still couldn’t see it.

Just thinking about the troubles of other scholars, the elderly are so dazzled that they are almost the same as blind people.

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

"That's upside down, and what can that kind of telescope look at? The lens is thin. Have you removed the telescope, it's different, right?"

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

"You are always willing to give the money to the people cheaper." Li Chengqi sighed.

"In a few days, I specially cooked tea sets, complete sets, which are similar to those for you, Brother San, and others, and will promote them in the newspaper."

Li Yi gestured to make Kung Fu tea.

He had to sell a batch of tea sets first, and then it became popular to drink Kung Fu tea, so that the sales of tea would increase.

Of course, Kung Fu tea can be made more than just green tea, but black tea can be brewed.

Li Yi said as he took a teapot and two tea bowls, opened the tea pot, grabbed some tea leaves and put them in the teapot.

Then pick up a bamboo woven thing from the side, open the plug, and pour hot water into the teapot from it.

"Brother Yi, what is this?" Li Chengqi saw that the water was still steaming and his eyes were on Li Yi's things.

"Which thermos is blown with glass and put in the mold. When there is air in the middle, blow the inside and the outside expands.

Leave a mouth behind and then paint silver inside like a mirror.

Then, like making a light bulb, it is vacuumed and heated.

The pot made in this way can keep it warm. Add a plug and a pot of boiling water will still be hot after a few hours."

Li Yi talked about how to make pot bulbs, using glass-blowing, mirror-making, and light bulb making.

"Want to sell this item?" Li Chengqi actually understood it. The process was simple, but in fact he couldn't make it.

"Sell it, just like a treasure. One is 200 pieces, and it can be replaced and maintained for free, just..." Li Yi said that he wanted high-priced service.

It broke, put the pieces together and took them to Zhuangzi, and Zhuangzi gave them a new one.

There is scale inside, so take it to Zhuangzi and clean it off.

The thermos plug is not easy to use, so I go directly to the farm to ask for it without having to take the original one.

200,000 yuan, all you can enjoy is this service. If you are unhappy, you will fall and change it for you.

"It should be the case if you don't have a lamp, one hundred pieces of fire." Li Chengqi thought of something else.

"Yes, I said in the newspaper tomorrow, what should I do if the glass is broken? Change it." Li Yi was so kind.

"How many thermos do you have now? I will take it away and send it to His Majesty. I will also have it at home to help you promote it."

Li Chengqi was not polite at all. He knew the cost was very low, so he didn't use it to resell it.

"I just worked for two days and everyone is still familiar with it. There are only 160 qualified ones, and there are more than 2,000 scraps."

Li Yi shrugged his shoulders when talking about the difficulty of production.

In the mold, the inner liner is blown against the outer liner, and if one is not controlled well, it will be put together.

When the vacuum is exhausted, it is easy to get hot and leak out, and it explodes with a bang.

"Okay, I'll hold all 160, I need to take it lightly." Li Chengqi didn't care how many of them were broken.

Craftsmen can gradually become proficient, which is convenient for use in winter, otherwise someone will have to watch the fire and be responsible for the hot water.

In the afternoon, he sent someone to carry it together and used straw mats, so he could not touch it, especially at the mouth of the pot.

I took away a thousand plugs and put them in water to try this plug.

He carried a thermos bottle filled with hot soup in his hand and entered the palace and headed straight to Baifu Palace.

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

Li Longji received news that King Song should have come from Li's village and brought a lot of things.

When he arrived at the place, the palace maid was carefully pouring boiling water into several thermoses.

Soak the plug in water, pour boiling water, and place the plug on it.

"The third brother is here. I'll show you this. The hot soup I poured in the farm at noon has been around for an hour and a half."

Li Chengqi asked someone to take five bowls, and he pulled out the plug and poured the soup from the inside and out.

The heat steams when the soup is poured out.

"It's mushroom, black fungus, egg-sleeved soup, and lean meat and carrots."

The focus of Queen Wang’s attention is so unique.

Li Longji reached out and touched the bowl, then blew a breath into the soup, and the heat hit his face.

"It's hot, it's still so hot after an hour and a half."

Li Longji said as he started blowing, putting his mouth against the edge of the bowl and sucking, turning his head to spit on the ground, and burning it.

The palace maid quickly came over to wipe it with a rag, and the clever eunuch ran to get the spoon.

Take the spoon and blanch it with hot water. Everyone scoops the soup and drink it one by one.

"The soup in my uncle's place is better than that in the palace. When I want to drink soup in the future, I will take it from Lijiazhuang."

Queen Wang discovered the correct use of thermos and filled soup.

"The palace maids and eunuchs in the palace don't have to be tired and watch the hot water." Concubine Dou Lu thought of the people who worked.

"Yes, I need to prepare more in the palace, but the fire still needs to be seen. They also heat up food and keep warm. Isn't it right?"

Queen Wang turned to ask her son.
