When Bai Jinli, who returned home, was thinking about whether to make something cool because it was too hot, she suddenly sneezed twice.

"Who's talking bad about me behind my back?" Bai Jinli couldn't help muttering.

"Sister-in-law, are you sick with a fever? I'll fan you the wind. ”

Bai Mo heard her muttering, and ran out of nowhere to take out a fan made of pu leaves to help her fan it.

With the artificial wind of white ink, Bai Jinli is really cooler, but this is not always a solution.

It seems that we have to find a way to cool down.

It's still modern, and this kind of stuffy weather has long been lying in the air-conditioned room covered with a quilt and munching on watermelon and ice cream.

In this backward ancient time, there was neither a fan nor an air conditioner, and it was not possible to wear shorts and short sleeves, so a few pieces of clothing were covered on the body, even if the material of the clothes was breathable, it would be hot.

Why don't you make some ice cubes?

In ancient times, if you wanted to cool down, you could only rely on ice cubes.

It's just that ice cubes are too expensive, they are all saved in the previous year, not to mention that ordinary people can't afford to use them, even if they are big families in the capital, ice cubes don't mean that you can use them if you want to.

Including the nobles in the palace, there are rules on how much ice can be used at this time of year.

Of course, none of this is difficult for Bai Jinli, because she knows how to make ice cubes.

"Bai Mo, I remember that there is a cellar in the backyard of the old mansion, right?" Bai Jinli asked.

"Yes, sister-in-law. A few days ago, the second fat brother also said that he wanted to put the fruits we recovered into the cellar. Bai Mo spoke.

"Well, that's good."

"Lin Shenyuan, do me a favor." Bai Jinli quickly ran into the house.

In the room, Lin Shenyuan was sitting on the side holding a cup of flower and fruit tea made by Bai Jinli himself, and he felt that it tasted very good.

"What's wrong?"

"Can you get me saltpeter? The more the merrier. ”

"Saltpeter? Well, you can. Lin Shenyuan nodded, didn't ask more, got up and walked out.

It wasn't long before he came back in and sat down, continuing to drink his tea.

"Lin Shenyuan, aren't you hot?" Bai Jinli couldn't help but ask curiously.

"It's not hot. The mind is calm and naturally cool. ”

“…… Otherwise, you're going to get angry! ”

“？？？” Lin Shenyuan.

"When you're angry, your whole body is cold, and it can cool down, but it's cool." Bai Jinli opened her mouth to explain.

“…… Scold. Lin Shenyuan finished his cup of tea, got up and walked past Bai Jinli.

As he passed by, he stretched out his finger and flicked it on her forehead, and then strode out.

"Hey, why did you leave?"

Bai Jinli didn't care about him, sat back at the table, and began to draw the summer version of the pajamas with a pen.

She had to ask Zhang to help her make a few pajamas for the summer, otherwise she would die of heat at night.

The weather has been unusually good lately, and it hasn't rained since she crossed over until now.

Especially in the past few days, the weather has become more and more sultry, and she roughly estimated that the maximum temperature would be almost thirty-seven or eight degrees.

After she finished drawing these, she went to the kitchen to try to make some beef jerky with the beef she bought from Erfat, and when she came out, she was even hotter and sweaty.

After resting for a while, I washed up briefly, and finally cooled down.

Lin Shenyuan's work efficiency is good in the end, Bai Jinli didn't wait long, and saw Chasing Feng with a few people coming to the door to send saltpeter to her.

With saltpeter, you can make ice cubes.

Bai Jinli filled a jar of water, found a larger container, and put water in the container.

Put the jar in the container and add a certain percentage of saltpeter to the container.

It didn't take long for the water in the jar to freeze.

Bai Mo and the others were dumbfounded.

The ice cubes were available, and she felt the need to make an ice bucket to use as a primitive freezer.

It's just that this matter is not urgent, and Bingjian needs to be made of bronze or wood, and the process is more complicated.

Bronze production is too cumbersome, time-consuming, and laborious.

For wood, you need some good quality and fine wood, such as mahogany, pear or cypress.

If she can draw the drawings of Bingjian, according to Carpenter Tan's craftsmanship, she should also be able to make them.

But the wood raw materials of Carpenter Tan's family are only average, and they are not as good as she expected.

It seems that she has to trouble Lin Shenyuan to help her get some good mahogany.

With the ice cubes, Bai Jinli instantly felt a lot cooler, and she wanted to make some simple ice cream.

The most primitive ice cream is easy to use without any fruit, as long as it has milk, sugar, ice, salt, etc.

The milk was the one she asked to get for her.

After mixing the milk and sugar together, Bai Jinli poured them into an airtight bucket.

The ice cubes were then placed in another bucket and some salt was poured into them.

Because the salt absorbs heat when it melts, it lowers the temperature of the ice cubes.

Once sealed, start shaking and stirring.

After a long time, her first bucket of ice cream was successfully baked.

I found a small bowl and dug some, she tasted it first, it was not bad, if she could add a little fruity flavor, I am afraid it would taste even better.

She dug up a few more bowls of the ice cream and gave it to everyone in the old house.

"Sister-in-law, what is this? It's sweet and refreshing, melts in your mouth, and it's delicious. ”

After Bai Mo finished eating, he felt that he was much cooler, and he couldn't help but speak very excitedly.

"It's called ice cream, and it's for the summer."

"Pear, you're too good, how did you come up with this kind of thing?" Tu Shi tasted two bites, and was so shocked that he was about to stare out of his eyes.

"I also listened to what others said, tried to do it, and I didn't expect it to succeed."

Not only was Tu quite shocked, but even Bai Jinli herself expressed her happiness.

She immediately instructed Chasing Feng to help her buy two cows to raise at home, and began to make yogurt, juice, popsicles and other things.

The ice cubes made Bai Jinli were put into the ice cellar first.

Saltpeter is recyclable, which means that with the right time and preparation, she can make as many ice cubes as she wants.

As for the ice cream, Bai Jinli tried it and felt that it tasted good, so she put some in a bowl, and put ice cubes below to cool, so that Bai Mo could send it home for Mrs. Li to taste.

She began to think about a problem.

Preserved fruit and pork are used to open a small storefront, and even many chain small stores are indeed good, but they can't make a lot of money.

This is the season when you want to sell ice cream, juice, yogurt, and so on.

Oh, and you can also make some milk tea and sell it together!

It's just that there is a problem, most of the people who like ice cream yogurt are women, or people who have more money in their hands, know how to enjoy, and like to hunt for curiosities.

Since she wants to start an ice cream business, she naturally has to do it perfectly.

In this way, the container for the ice cream was on her radar.

After thinking about it, Bai Jinli still felt that it was good to be able to fire the glass.

Nowadays, there are already glass products handed down from other countries.

It's just that it's more expensive, and ordinary people can't see it, and they can't afford it.

She could find a way to make glass, but if she wanted to use it in ancient times, she would need to think a little more about it.

If you can find a way to find out about the glass firing process of those people in the foreign countries, and then combine it with her glass firing process, it will definitely be successful.

If the glass can be fired, then the mirror that she has been dreaming of can see people very clearly will soon be available.

She decided to find Lin Shenyuan to do this.

After all, she is busy, and she has to go to school to write scripts, make ice cream and preserved fruits, and so on.

After Bai Jinli was busy finishing these, the sky was gradually getting dark.

As the sun goes down, so does the temperature.

The trees began to sway in the wind, and people who had been tired from the day came back from the fields.

Today's affairs in the old mansion have been busy, and Tu and Er Fat have also gone home to rest.

Bai Jinli locked the door of the old mansion and followed Bai Meng and Bai Mo to the house.

After eating, Bai Jinli gave the drawings she had drawn to Zhang, and asked Zhang to help her make summer pajamas.

When Zhang saw the drawing, his expression was indescribable.

Surprised, weird, blushing, red!

In the end, the ancient people were more conservative, and after seeing the sundress and short-sleeved shorts pajamas painted by Bai Jinli, they couldn't hold it anymore.

In addition to the summer pajamas she was going to wear, she also spent the men's version.

In addition, there is a relatively conservative underwear.

Presumably, Zhang's face turned red because he saw this very revealing underwear.

"Pear, this thing...... Why don't I sew a few more belly pockets for you? Zhang's face was red and his voice was low.

"No, no, sister-in-law, it's easy to sag your breasts when you wear that thing in your belly pocket, which is not good for your health. The thing I drew is called a bra, and wearing it shows off a woman's figure.

I'm sorry for you, so I'll sew one according to what I drew first, and when you put it on, you can see how good this thing is. Bai Jinli said stubbornly.

"That's fine, but you'll have to wait a couple of days." Zhang looked at Bai Jinli's expression and knew that this matter was not negotiable, so he had to nod and agree.

"Well, it's okay, I can wait." Bai Jinli didn't care about the length of time.

In fact, if she could, she would rather do it herself.

However, she herself is a handicap party, and she really can't do it, so she has to ask for help from the best sister-in-law Zhang who does the embroidery work by hand at home.

After solving this matter, Bai Jinli went out with Mrs. Li for two more laps to eat.

When she came back from eating, she stared at Mrs. Li and danced the square dance for a while, and then went back to the house to stop.

In the house, Lin Shenyuan helped her prepare the bath water as always.
