When I went down the mountain, I was still majestic, but when I got home, I wilted in an instant.

Then I realized that I was really just a momentary interest before, and I suddenly wanted to open a store or something, and I really didn't think about how to do it.

recalled the snack bar he had been to in his previous life, and it seemed quite simple, but Lin He knew very well that it was really just a look.

Especially when she thought of one thing, there is no refrigerator in this world, and in the summer, the pork in the morning will start to stink at night.

However, Lin He tried to recall it again, as if she had heard Yu'er say before, popsicles or something, but she didn't pay attention to it at that time.

hurriedly took two steps and caught up with Li Changhui, who was stopping to cut pigweed.

"Brother Hui, is ice expensive in summer?"

"Ice?" Li Changhui straightened his waist and thought for a while: "Ice to relieve the heat should not be expensive, and ordinary people can afford to use it, even if you eat ice drinks, you can basically buy one if you are a little more willing to do so." ”

Lin He was surprised: "It's so cheap, I'm talking about summer, alas, doesn't the ice melt quickly?" ”

She had the impression that ancient ice cubes should not be stored in ice cellars in the winter and used in the summer, and they were very expensive, and only the truly wealthy could afford to use them.

Isn't it?

Li Changhui looked at her even more unexpectedly: "Yes, it's because of summer, so it's cheap, and in autumn, the price will rise." ”

Lin He suddenly became interested: "Why is this?" ”

Li Changhui said: "Have you ever heard of saltpeter? ”

Lin He blinked, and before she could react otherwise, Li Changhui continued: "But I forgot, you rarely went to town before, you shouldn't know this."

"Saltpeter was originally a kind of ore powder commonly used in alchemy in Taoist temples, and later it was discovered that saltpeter added to water can actually condense into ice, so this method was soon promoted to the entire Da'an Dynasty."

"Saltpeter is not expensive, almost every household can afford it, and after the ice cubes melt and dry, saltpeter powder can be reused."

"However, saltpeter ice cannot be eaten directly, but saltpeter can be added to ice bottles to condense clean water into ice, but this is more time-consuming and labor-intensive, so ice drinks are slightly more expensive."

Li Changhui's explanation was a bit unexpected, Lin He really didn't expect that everyone would already know how to make ice chemically?

"So, everybody?"

Even though Li Changhui has said it very clearly, it still feels incredible.

However, this time, Li Changhui shook his head: "Not everyone knows, but there are many people who know." ”

So how do you know?

I almost blurted out these words, but fortunately I held back.

This time, she saw from Li Changhui's face that the matter of saltpeter ice making is common sense for some people, but for most people, it should still be unclear.

But how did Li Changhui know so much, did he learn it from the military camp when he was in the army?

First read and learn words, then medical herbs, and now it is a 'common sense' that ordinary people don't know.

I always feel that this is not something that can be learned by joining the army.

Thinking of this, Lin He suddenly blurted out: "By the way, Brother Hui, you haven't told me yet, do you recognize the herb that removes scars?" ”

When I talked about this yesterday, I was hooked all night by the other party's sentence that she came to the mountain alone, and I completely forgot about it.

Li Changhui also thought she had forgotten: "Didn't you say that it's not bad money?" ”

So it's really not necessary to grow medicinal herbs or something.

Just take care of the field, and the rest of the mess will delay time and energy.

However, Lin He shook his head vigorously: "Don't, I'll try to plant less, when the time comes, you show me a piece of land, you don't have to worry about anything, I'll take care of it by myself, you just need to help me buy some medicinal seeds." ”

Dig up the mountains and plant home?

That's really unnecessary, it's not like taking off your pants.

Or get some seeds back, with the blessing of her spiritual power, it will definitely be able to grow very well, and when the time comes, it will definitely sell well if you boil a pot of ointment that specializes in removing scars without leaving traces.

You must know that the parents of the body, regardless of men or women, as long as they have scars, I believe they will be willing to buy a little ointment to try.

Thinking about it, he glanced at Li Changhui again.

Of course, Li Changhui is not among ordinary people.

At this glance, I just caught a glimpse of Li Changhui also looking at him, and his eyes were full of helplessness.

But he still nodded: "Okay, go to the pharmacy tomorrow when you go to town, and if you don't, ask the owner of the grocery store to help you find it." ”

Lin He was instantly excited: "Thank you, Brother Hui, you are really good!" ”

Li Changhui shook his head, the little chef also had a lot of ideas, if he really did something, it still wouldn't work, even so, he also admitted it, who let this little chef bring it back personally.
