The whole family traveled through the hidden mountains, and the general always came to get the wool

As the beginning of autumn approaches, the weather becomes hotter.

Su Weixi's family misses the air conditioner from their previous life very much.

Because people would come to the wooden house from time to time, it was not easy for the Su family to take ice directly from the space.

I can only secretly put ice cubes in the room to cool down at night.

At this time, Father Su remembered that he had asked Shen Jingzhou to bring a few bags of saltpeter back to the valley.

"My daughter, come here and see what this is." Dad Su threw four sacks in front of Su Weixi.

Now, thanks to his martial arts training and the effects of the spiritual spring water, Father Su is much stronger than others, and carrying four sacks is like a piece of cake for him.

"What the hell is this? It's so hot, I don't want to watch it." Su Weixi, who was lying on a recliner under a tree, was too lazy to get up.

It's just that the day is too hot, and I've been really bored recently.

Father Su looked at his lazy daughter and couldn't help but smile helplessly. He squatted down and untied the rope that tied the sack.

"Are you sure you don't want to take a look? It's something you've always wanted."

Su Weixi's father's words finally aroused a little curiosity. He stood up and took a look, and found that it was saltpeter.

“Ahhhhhh, Dad, where did you get that?”

"I asked Shen Jingzhou and the others to bring it here before, but I was too busy, so I threw it in the warehouse."

"Dad, go get some water and prepare a big bucket so we can make ice."

"Okay, it's up to you."

One of the people who came to build a house for Shen Jingzhou knew how to dig a well. In addition to digging a well for the wooden house, he also helped the Su family dig a well in the yard and near the chicken coop.

There are now four wells in the valley, and people no longer use river or lake water for domestic purposes.

Before, the water used by the Su family was either taken from the space or filtered and purified by themselves using river or lake water.

With these two wells, using water has become much more convenient.

After all, the easily consumable materials in the space are mainly used for emergency purposes.

Soon, Su Weixi used the saltpeter method to make ice and made several large buckets of ice.

There is a bucket of ice in every room of the house, the living room and the kitchen.

I watched as Su's father went to the warehouse and carried back a few bags of saltpeter.

Su Weixi thought of the old, young and sick people in the cabin and decided to make some ice for them to use.

Anyway, this saltpeter was obtained with the help of others, and it can be used repeatedly.

Father Su came out of the room and saw a few more buckets of ice. He looked at his daughter in confusion.

"Girl, we have enough ice at home, why are you still making it? Are you addicted?"

"Well, there are a bunch of old, weak and sick people in the cabin. They must be feeling uncomfortable in such a hot day. Dad, please send some to them." Su Weixi said awkwardly.

Because so far, she has not seen anyone except Nanny Sun and Songzi who follow Qing'er all day long.

There wasn't much interaction between the two sides, except that occasionally Songzi would come over to deliver some dishes made by the chef or pastries made by the cook.

Father Su also knew that his daughter was feeling awkward, so he didn't say anything. He just picked up a few buckets of ice and left.

I went there alone, and when I came back, there was a follower following me.

Shen Jingzhou: I'm not an annoying follower!

When they got closer, Shen Jingzhou spoke first: "Miss Shen, Uncle Su told me that you can make ice?"

"Yeah." Su Weixi answered indifferently. She still felt a little resentful towards Shen Jingzhou for repeatedly disturbing her family's life.

"I wonder if Mr. Shen can buy the ice-making recipe?" Shen Jingzhou asked with a smile.

"Oh? I wonder how much price Mr. Shen is willing to offer?" Su Weixi asked with a smile.

"Um, how about this, Miss Su, please name a price." Shen Jingzhou didn't know what the appropriate price would be for a moment.

In a sense, this recipe is priceless, especially since the Su family has done him a favor. He was afraid that if he said the price was too low, the Su family would think he did not respect them.

Father Su looked at his daughter who was playing tricks on others again and had no choice but to interrupt her.

"My daughter, Mr. Shen bought this recipe not only to make money, but also for the soldiers on the border." What Su's father meant was to hint that Su Weixi could sell this recipe to Shen Jingzhou.

"Yes, Miss Su. To be honest, the weather this year is unusually hot, and many soldiers in the Xiao family's military camp have fallen ill from heat stroke." Shen Jingzhou said with a slightly sad expression.

There is a reason why Shen Jingzhou cares so much about the soldiers of the Xiao family, because the mistress of the Xiao family is his aunt, and they are a natural community of interests.

In recent years, the old emperor withheld food and medicine from the Xiao family, and it was basically the Shen family who secretly raised food and medicine and sent them to the military camp.

"Since Mr. Shen is so caring about the soldiers, I will give you a lower price." After saying this, Su Weixi pretended to be in deep thought.

Shen Jingzhou, who was watching Su Weixi thinking, became a little nervous.

"Miss Su, just name your price." Shen Jingzhou said with pain.

"Then one hundred taels will do." Su Weixi said casually.

"What? One hundred taels? Miss Su, are you sure?" Shen Jingzhou was stunned.

"Yes, that's one hundred taels."

"You don't think about it anymore?"

"Why are you so long-winded? Do you still want to buy it?"

"Buy, buy, buy." After saying that, Shen Jingzhou took out a silver note from his pocket and handed it to Su Weixi.

Su Weixi took it and looked at it. Wow, it was actually a silver note for one thousand taels. He looked at Shen Jingzhou in confusion.

"The extra ones will be used as snacks for Miss Su. Miss Su, can you show me how to do it now?"

This snack costs a lot, many times more expensive than the recipe.

However, Su Weixi accepted it with peace of mind. He knew that Shen Jingzhou would not only use the recipe in the military camp, but also make ice and sell it to dignitaries.

By then you'll earn much more than this.

"We have run out of materials today. Please come tomorrow at noon."

"Okay, then I'll trouble Miss Su."

.......

"Okay, then we can dry the saltpeter and reuse it again."

"But you have to be careful. The ice mixed with saltpeter in the big barrel outside cannot be eaten. It can only be used to cool down. If you want to eat it, you have to use the ice in the small barrel inside."

"Wow, sister, you are so awesome."

"In addition to cooking, Miss Su is also very smart."

The two flattering voices came from Qing'er and Shitou.

This morning, after the two of them knew that Su Weixi could make ice, they followed Shen Jingzhou here.

At this moment, the two of them were leaning over the bucket and poking the ice cubes with their fingers. They still couldn't believe that making ice was so simple. Why hadn't they thought of it before?

"I never thought that saltpeter could be used to make ice. No one has discovered this before." Shen Jingzhou exclaimed as he looked at the ice cubes that had just formed in the bucket.

"Because saltpeter is usually only used in small amounts in medicine, it is naturally difficult to detect."

"I wonder where Miss Su learned this method from?" Shen Jingzhou knew that the Su family was very mysterious, but he didn't know they had such ability.

"I found it when I was bored and reading some books, but the book was lost when we moved to the valley." In order to avoid asking a hundred thousand whys, Su Weixi immediately said that the book was lost.

Then he changed the subject, "You'd better look for saltpeter mines everywhere if you want to make a lot of ice."

"Thank you Miss Su for the reminder."

Afterwards, the three of them had lunch at the Su family’s house before leaving.

Five days later, Shitou came over and said that the Su family no longer needed to prepare ice for the cabin, as the saltpeter that Shen Jingzhou had sent had already arrived.

Also left behind were ten bags of saltpeter for Su Jiaxin, as well as a large pile of cloth and some daily necessities.
