If you can make ice at home, it will solve a big problem. In the hot summer, you can add a smoothie as a special feature in the shop, add fruit juice, dried nuts, and raisins for people to taste.

Although Daqi's law prohibits private ice-making business, she doesn't sell ice and enjoys it herself, so there is no problem.

If you have this condition, you can build a super large cold storage, open a separate cold storage according to the lease method of your own house and the ice shop, and rent it to the rest of the restaurants. I believe the other party is very willing.

This saves costs compared to back-and-forth transportation, and also ensures the quality of ingredients.

Kyoto is different from Daqibei. It rarely snows in winter, but after a winter rain, the leaves fall and the temperature drops sharply.

In October of the lunar calendar, there is first snow in the Northland, and Kyoto is still green.

Li Haitang calculated the time and decided to write a letter to Ji Qiu, telling him to go to the mountains to help burn the cages at home and dry the house.

No matter how good the yard is, it will be dilapidated if no one lives in it for a few years and is not popular. In the backyard of our house, there is a cold pond. From the cold pond, a black-skinned fish can be caught. It has few spines and the meat is very tender. The slices are boiled in hot water, and then poured with oil to make a big steaming pot of boiled fish. Sitting by the window at home enjoying the snow, quietly watching the cat

How comfortable it is in winter.

Li Haitang likes this kind of life, eating and waiting to die, eating too much and being lazy, spending a lot of time thinking about the sunrise and sunset instead of worrying about some inexplicable things.

Xiao Lingchuan heard the report from his subordinates and learned that his wife was at the restaurant, so he put down what he was busy with and hurried to Songhe Street.

"Husband."

Li Haitang stood up, her face flushed, she was still fooling the wild man last night, and she had a day off today, no, she was caught so soon.

The lie was exposed and her face was hot.

Xiao Lingchuan waved his hands indifferently, that's all, it's not easy for a lady to lie on the bed for two months, and he supports her if she wants to go out for a walk.

Xiao Lingchuan glanced at the plate on the table, and found that the food on it had hardly been touched. Obviously, Li Haitang's appetite was not good.

"I haven't had time to eat yet."

As soon as Xiao Lingchuan came, Wu Fu, who was about to sue, exited the door awkwardly, leaving space for the husband and wife.

I don't know what kind of private conversation these two had, anyway, every time, she was kicked out, wanting to gossip, no one gave her this chance.

"Husband, Cui Niang showed me the expense booklet, and I suddenly discovered that we can make ice by ourselves to save costs."

Li Haitang had a new idea, and told the wild man immediately, anyway, she couldn't get saltpeter, so she had to rely on Xiao Lingchuan in the end.

"Is it reliable?"

It is not difficult to find saltpeter, but there are not many high-purity ones. Besides, he has not heard of anyone who has mastered the skill of making ice.

There is a dedicated ice maker in the palace. It is not that there are no businessmen who want to touch it. After all, no one is stupid and can see huge profits from it. However, ideas are ideas, and they are not realistic after all.

First of all, technology is a major difficulty.

"Don't forget where your wife came from."

Li Haitang had a sullen look on her face, she has solved the most worrying problem today, she is in a good mood at the moment.

Mo Ruhai became her subordinate and managed the shop from now on. As the boss, she didn't have to do it herself, just wait for the money to be collected.

"Okay, I have some here."

Xiao Lingchuan's eyes were deep. What he didn't say was that he had saltpeter powder, because he had been researching and developing gunpowder recently.

When his brother went to the outer seas, he discovered that the gunpowder in the outer seas was extremely powerful, and he found many ways to purify the saltpeter.

"That's great, now, let's try it out."

Li Haitang raised his eyebrows, shut up wisely, and didn't ask the savage husband where the saltpeter came from.

The more she knows about these things, the more tiring she gets. She doesn't care.

With the saltpeter in place, Li Haitang first took some pure water and put it in a jar, and then asked someone to prepare a large basin.

She poured clean water into the wooden basin, placed the jar in the center of the wooden basin, and closed the lid.

Finally, a large amount of saltpeter was poured into the water.

The time to witness the miracle is coming. In order to show that this matter is not so easy, Li Haitang mysteriously recited a spell.

Xiao Lingchuan was helpless, no matter how you looked at it, the lady didn't seem to be making ice, but a great dancer.

After a while, Li Haitang slowly opened the lid of the jar. He held the jar in front of his savage husband.

"Husband, try the ice!"

Li Haitang felt the coolness and was very confident in making ice.

Xiao Lingchuan nodded, easily smashed the ice in the jar and poured it out.

The ice is very firm, and the taste is sweeter and more mellow than that in winter. The water with saltpeter added can be reused. As long as the water evaporates and recrystallizes into saltpeter, it can be reused.

Compared with repeatedly transporting food materials, it is simpler to use saltpeter to make ice. Not to mention saving a fortune, it can also benefit oneself.

Xiao Lingchuan was expressionless and numb, but he was quite surprised in his heart.

Daqi expressly forbids reselling ice cubes, but there are many prohibited things. Illegal salt sales are prohibited in the south. Has anyone listened? Otherwise, how could the Chen family accumulate a large amount of wealth?

"It's Yaohuazhai. It's a pity. I hired a good shopkeeper."

Li Haitang took the savage husband's arm and shook it, and the problem appeared before his eyes again.

If you don’t want to do rouge and gouache business, what should you do?

Such a good location, a tall shop, you can't buy some countertops that are not good.

She can see that those rich people are not afraid of expensive at all, but are afraid of being too cheap and falling in price.

Therefore, the exorbitantly expensive soy sauce bottles and sewing baskets were slaughtered with peace of mind when everyone knew that they should not be so expensive.

"Bookstore."

Xiao Lingchuan found a way for his wife.

On Songhe Street, there are more than a dozen bookstores, all of which sell books related to scientific research.

The boss was afraid of getting a bad reputation, so he resolutely refused to sell some vernacular and miscellaneous books, otherwise it would ruin his reputation if it spread out, and if a scholar came in, he would be said a word, and he would be willing to degenerate.

Selling books requires a lot of investment, but the later returns are high, and no one will come to the door to smash and touch the porcelain. The price is open and transparent, which virtually saves a lot of trouble.

"Husband, there are three floors in that area. Is it suitable for a bookstore?"

All Li Haitang thought about was how to make money from women, but he never thought about selling books.

"Suitable."

Xiao Lingchuan didn't explain too much, but left room for imagination to his wife.

Li Haitang lowered his head, pondering the feasibility, from the admiration these young ladies have for the man who wrote the storybook today, it can be seen how boring they are in the boudoir. Daqi does not have a computer, no internet, and the ladies of high families are all literate. When they have nothing to do, they just find someone to talk to, listen to operas, and their thirst for books should not be small.
