Before Qi Mo left, he had found a record of saltpeter in the book, but it was only a few sporadic strokes, probably saying that it would be used in the manufacture of gunpowder, and as for making ice, there were only a few strokes, but he did not say how to do it.

Qi Ruo didn't care about Qi Mo's instructions when he left, asking her to wait for him to come back, and there was nothing to do, so he just went to Jinzhou City to see a doctor and went directly to buy a few saltpeters.

She didn't know how to use this saltpeter ice, so when she went to buy saltpeter today, she tried to ask the shopkeeper, but the shopkeeper said that he had never heard of this method of making ice, so she had to move back and tinker with it herself.

She thought about it, first brought a basin of water, then put saltpeter in the water, and after a while, she wanted to reach in and try it, but she hesitated a little to think that this thing could be used as gunpowder.

"Since you can make ice and you can eat it, there should be no problem."

Qi Ruo gritted his teeth and put his left hand into it

The expression on her face softened, and then there was a bit of surprise: "The fruit is really cold." ”

It's just not to the point of freezing.

Qi Ruo looked at the saltpeter and fell into thought, could it be that it had to be completely melted to form ice?

Thinking like this, Qi Ruo was not in a hurry, so she let it go to the yard to pick up herbs, but when she came back to look at it, she felt that even if this saltpeter was purified, it would not freeze.

The water is just going to be colder again, but it's far from freezing.

She thought for a moment, put another saltpeter in it, and then found a wooden basin to cover it over the water-filled wooden basin.

When I came back in the evening, the water was still not frozen.

Qi Ruo glanced at the saltpeter placed on the side, and there were four pieces, and with a ruthless heart, he put another saltpeter into it.

She held her cheeks and looked at the wooden basin, her face full of grievances, as if the water in the wooden basin had bullied her.

Can you not be aggrieved? Not to mention that she spent a lot of money on these saltpeters, but they were also more expensive than ordinary objects, at least she felt that she was just a few clear stones, where could they be worth these silver? But if you want to make more money, you have to invest money in it first.

It was late now, and it was not a good idea to wait on the sidelines, so she simply went to wash up and go to bed. It's just that she is tossing and turning in her heart, where can she sleep well?

When she got up, she couldn't wait to uncover the wooden basin to see, the water was much colder, and the saltpeter had melted, but it had not frozen.

"Can't you just put it in the water?"

Qi Ruo simply took a large wooden basin, put a small wooden basin in the large wooden basin, and then put some water in the small wooden basin, and finally put the saltpeter in the large wooden basin with no water, next to the small wooden basin containing the water.

After waiting for a long time, the water did not move.

Maybe there is not enough time.

Thinking like this, she got up and went to look at the basin of water where saltpeter had been placed before.

She still has to see if the water that has been put into saltpeter can still be eaten, after all, when it freezes in the future, it is necessary to put vegetables and fruits, and it can also be made into ice products at that time, if it is harmful to the body, it is not good.

The basin of water was really cold to the touch.

Qi Ruo didn't dare to drink it directly to try it.

She first took a spoonful of water and watered the flowers in the courtyard, but the flowers did not change much, but she had to wait another day to see.

After thinking about it, she went outside to catch a small fish in the field, and took some water to keep the small fish inside, and the small fish was not very uncomfortable, so she waited to see if there would be any changes over time.

After doing these things, Qi Ruo looked at the water in the small wooden basin again, and it didn't change much at all, and it was much worse than the water directly put in saltpeter.

But if it is said that Fang Cai's method can be frozen, but it is not frozen because the saltpeter is not put enough, then there is no need to sell ice anymore.

Such expensive ice, not to mention whether anyone buys it, even if someone buys it and sells it with vegetables and fruits on ice to earn the money of wealthy families, it is not something that ordinary wealthy families can afford, and those wealthy families do not often buy it, just try it.

In the past, the number of ice merchants who needed it has also decreased sharply, and it has become a loss-making business.

But what if there is another way to freeze?

Qi Ruo looked at the three saltpeters in the big wooden basin, and had no clue for the time being, so he had to move all the saltpeter out, thinking that it was time to clean the house inside and out, and went to carry a bucket of water to pour it into the big wooden bucket.

After putting down the barrel, she saw the saltpeter that she had put aside, and thought that the owner of the saltpeter seller said that if she left the saltpeter directly outside, she was afraid that it would melt, so she hurriedly picked up the burlap bag and put them on one by one.

Just as he was about to put the last piece in, a villager suddenly came to the door.

"Doctor Qi, it's not good, Doctor Qi, my mother suddenly fell into the dam, come and take a look."

Before the words are finished, the people have arrived.

The villager stepped forward and grabbed Qi Ruo's wrist, Qi Ruo's hand was soft, and the saltpeter fell to the ground with a "plop" sound, falling into the big wooden basin, and the water splashed on the ground.

But Qi Ruo can't manage it so much, it's important to save people.

She immediately went to her pharmacy with the hem of her skirt and asked the man about his mother's symptoms as she went.

The man said it upside down, but fortunately, Qi Ruo was alert enough about the symptoms, and soon learned what he wanted to know from the man's mouth, and quickly put the things he needed into the medicine box and followed the person.

When Qi Ruo came back from a busy day, it was almost dinnertime, and Aunt Wang had already prepared the meal.

She was going to wash the dishes after eating, but she was robbed by Aunt Wang to do it, and she did feel a sore back, so she helped her waist back to the house.

But as soon as she sat down, she remembered the saltpeter she had fallen into the water, and hurried to the stove room to see, but as soon as she stepped into the stove room, she felt a little cold.

She moved the kerosene lamp and looked closely, only to see a piece of ice in the small wooden basin, from which the chill came from.

She was overjoyed, and couldn't help but call Qi Mo to come and see, but when the words came to her mouth, she remembered that Qi Mo was not there, and he was still out of the boat.

With a smile on her face, she picked up the small wooden basin in the big wooden basin and put it aside, and touched the ice with her hand, which was really chilling.

"I didn't think it would be a mistake." She couldn't help but say to herself, "It really didn't take any effort to get it." ”

If you put the ice here and melt quickly, you have to find a shady place to put it.

After thinking about it, Qi Ruo went to find Aunt Wang and Dr. Lin, and the family put the ice in the sweet potato nest at the back of the house, and then took the sweet potato nest again and covered it with a few shovels of soil.

The sweet potato nest is found in almost every household in the township, so a deep pit is dug and some shelf-stable things are put in it on weekdays, which does not see sunlight all year round, and it is very cool, so that the solid ice should be able to melt slowly.

Qi Ruo left good news for Qi Mo, and Qi Mo also brought back good news for Qi Ruo.

"Guess how much silver I sold for three buckets of vegetables?"

As soon as Qi Mo saw Qi Ruo, he picked up the person and turned around, and asked like this after putting the person down.

Qi Mo was so swaggering in front of the public, causing Qi Ruo's cheeks to turn crimson, and he hung his head and didn't want to look at him.

After a long while, she asked, "How ...... How much? ”

Qi Mo shook a finger in front of Qi Ruo.

Qi Ruo was a little incredulous: "Ten ...... Ten taels? ”

Qi Mo nodded affirmatively: "It's ten taels." ”

Qi Ruo has an account in his heart.

They only spent one penny of silver to buy ice, and only two pennies of silver for three large wooden barrels, and the vegetables they planted, the vegetable seedlings were not expensive, and they spent some effort on weekdays.

This time, there were only three buckets of vegetables, Qi Mo talked to the brother he partnered with, and the brother was also righteous, so he agreed in one bite and didn't pay the boat fare.

"That's really profitable."

Those dishes are just ordinary dishes, Qi Ruo thought that he could make some money by selling vegetables across the border, but he didn't expect to make so much money.

"Really, the lives of those wealthy families are really not ordinary luxury."

Qi Mo became more and more bold, and directly knocked Qi Ruo's forehead with his fingers: "If we also have a lot of silver in the future, then we have to eat it if we want to, why hold it back, do you say yes or no?" ”

Qi Ruo covered her mouth and squinted her eyes with a smile: "That's right." ”

"But ......" Qi Ruo's face was mysterious, with some pride in his eyes, and he deliberately lowered his voice, "Since you have gained, then I have to show you what I have gained." ”

Qi Ruo's appearance made Qi Mo's heart itch, he looked around, and when he saw that there was no one on the road, he went up and kissed Qi Ruo's eyes.

Before Qi Ruo became angry, he didn't forget to pat a sycophant: "You look good when you smile, and your eyes are even more beautiful, and there is light." ”

Who doesn't yearn for the light?

The same is true for Qi Ruo.

Hearing this, she couldn't help but look at Qi Mo's eyes fixedly, sword eyebrows and starry eyes, a pair of eyes were rare perseverance and clarity, as if the world could not make it a little dirty.

A person's eyes will gradually become cloudy with age and experience, and only when a person is smiling can he get a glimpse of his true face, but Qi Mo is different, as if all the sins and sufferings can't leave too many traces in his eyes.

Qi Ruo thought, maybe it didn't stay in his eyes, but it stayed in his heart, where few people could see it.

When she got to the outside of her house, Qi Ruo didn't go in, and Qi Mo didn't ask much, so he followed her to the back of the house and entered her sweet potato nest with her.

"Is it cold in our sweet potato nest? And what about sweet potatoes? ”

Qi Ruo smiled and blew the fire fold on fire, and Qi Mo saw the situation in the sweet potato nest clearly.

I saw that there was not a single sweet potato in the sweet potato nest, but there were several pieces of ice and some vegetables.

"Sweet potatoes can't be left in a place where there's too much moisture, so we just move to the other side, and we're going to use them for ice. And I've tried, and the hard ice made of saltpeter can be used, and it won't have any bad reaction to people. ”

"Daughter-in-law, you are amazing!" Qi Mo said that he was aggrieved again, "Daughter-in-law, I said that I would get it when I came back, and you didn't give me a chance to perform." ”

Qi Ruo couldn't stand Qi Mo like this, so he hurriedly reached out and covered his mouth.

Qi Mo's eyes widened, obviously he didn't cover it tightly, he wanted to make an appearance that he was coerced, shaking his head vigorously, and his eyes were even more aggrieved.

Qi Ruo glared at him, and wanted to withdraw his hand, but before he could withdraw it, he felt a burst of wetness in his palm, and a soft thing swept over.

Qi Ruo's face was flushed with shame, and he turned around and wanted to run, but he was hugged into Qi Mo's arms, and he grabbed his lips all of a sudden.
