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

All they can find are those who are more wealthy, at least the two sides must know each other.

When they entered a house, they stayed for about a quarter of an hour, and when they came out, they were delivered to the gate.

Looking at the expressions of both sides, they were very happy.

The stalker can't figure out what's going on even if he wants to break his head.

Until a family sent it out: "That mirror is so easy to use, three days, right?" I'll wait, no hurry, no hurry. ”

"Yes, three days, you are early, if someone else tries again, you have to continue to the back row." This Yu Huaide is in charge.

The stalker got a word, mirror.

Selling mirrors? Need help selling mirrors? The Li family Zhuangzi knows all about the mirror.

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

Yu Huaide: They are indeed selling mirrors, glasses, myopia glasses and flower glasses.

Scholars are generally more likely to be nearsighted, and wealthy families are more likely to be nearsighted, and they can afford to light oil lamps and candles.

If you are in that kind of light for a long time, you can't adapt to it, so you won't be short-sighted.

Eyesight is easy to get with age.

Yu Huaide and they first found rich people to sell, and the box contained lenses of various powers, and tried them one by one, but the left and right eyes may not be the same.

Try it and write it down, and when the glasses are made and delivered to the door, they will give you the money.

One lens is ten and the frame is free.

Sell one, Yu Huaide and they get a commission.

People who don't have money don't care about it first, otherwise it's cheap, how can they make money from rich people.

"Brother Yi, are you going to let go of the glass for sale?" At noon, Li Chengqi came over, and after he knew the situation, he wanted to ask.

"Scholars are short-sighted, and it takes a lot of effort to be an official, and it also affects their lives, so since they can make it, they will use it.

After a while, I think about how to work on the frames, the more beautiful frames, the higher prices.

Ordinary ones can be cheap, and people with myopia and blindness can wear them for some money. ”

Li Yi found that when the two hundred and twenty students were in class, some of the students just couldn't see the board books, and they were all placed in the first row, but they still couldn't see them.

Thinking about the distress of other scholars, the old man is dazzled, and he is almost the same as a blind man.

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

"That's upside down, and what can that telescope see? Thin lenses. You've dismantled the binoculars, it's different, right? ”

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

"You're always willing to give things that make money to the people cheaply." Li Chengqi sighed.

"In a few days, I will burn a tea set, a complete set, similar to that of you and the third brother, and it will be publicized in the newspaper."

Li Yibi made a gesture of making 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 tea sales rose.

Of course, kung fu tea can not only be drunk with green tea, but also brewed like black tea.

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

Then pick up a bamboo object from the side, open the stopper, and pour hot water into the teapot from inside.

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

"A thermos, blow it with glass, put it in a mold, and when there is air in the middle, blow the inside, and the outside expands.

Make a hole in the back, and then apply silver to the inside as if you were making a mirror.

Like making a light bulb again, I vacuum, and heat the mouth that remains.

In this way, the pot can be kept warm, add a stopper, and after a pot of boiling water is placed for a few hours, it is still hot. ”

Li Yi said how to make the pot gall, using the process of blowing glass, making mirrors, and making light bulbs.

"This thing is for sale?" Li Chengqi actually understood, the process was simple, but in fact he couldn't do it.

"Sell it, sell it as a baby. Two hundred one, free replacement and maintenance, is ......" Li Yi said to a high-priced service.

If it is broken, the pieces will be roughly put together, and it will be taken to Zhuangzi, and Zhuangzi will give a new one.

There is limescale in it, take it to Zhuangzi, and Zhuangzi will wash it off.

The thermos stopper is not easy to use, so you can go directly to Zhuangzi to ask for it, and you don't need to take the original one.

200,000 yuan, what you enjoy is this service, if you are not happy to fall, you will change it.

"You should be the same if you don't have a lamp, one in a hundred." Li Chengji thought of something else.

"Yes, tomorrow in the newspaper, it's so expensive, what if the glass is broken? Change. "Li Yi is as good as a stream.

"How many thermos do you have now? I'll take it away and send it to Your Majesty, and I will have it at home to help you promote it. ”

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

"Just two days after doing it, 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 he talked about the difficulty of production.

In the mold, the inner tank blows against the outer tank, and one is not well controlled.

When vacuuming, the heat seal is also easy to burn and leak to the side, and it explodes with a bang.

"Okay, I'll hold all one hundred and sixty, and I need to handle them gently." Li Chengqi didn't care how many were broken.

Craftsmen can gradually become proficient, and it is convenient to use it in winter, otherwise someone will have to watch the fire there and take care of the hot water.

In the afternoon, he sent someone to carry it together, and it was mated with straw, but it could not be bumped, especially at the mouth of the pot.

A thousand plugs were taken, and they were poured with water to try the plugs.

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

In less than a quarter of an hour, Queen Wang arrived with the child in her arms, and after a while, Li Longji arrived.

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

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

Soak the plug in water, pour boiling water and put the stopper on.

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

Li Chengqi asked people to fetch five bowls, and he pulled out the stopper and poured the soup from the inside.

The soup is steaming hot when it is poured out.

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

That's what makes the Queen so special.

Li Longji reached out and touched the bowl, and blew on the soup again, and the heat hit his face.

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

Li Longji began to blow as he spoke, put his mouth on the edge of the bowl and sucked it, turned his head and spit on the ground, hot.

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

The spoon was taken, scalded with hot water, and everyone scooped the soup and drank it one by one.

"The soup in my uncle's place is better than the one in the palace, and if you want to drink soup in the future, you will take it from the Li family Zhuangzi."

The queen found the correct use of the thermos and filled the soup.

"The palace maids and eunuchs in the palace don't have to be tired of looking at the hot water." Doulu Guifei thought of the people who worked.

"Yes, I have to prepare a few more in the palace, but the fire still depends on it, and they themselves have hot things to eat and warm. Isn't that right? ”

The queen turned to her son and asked.

"Ahh The little guy stared at the soup bowl as if I was going to drink it too.
