Seeing the water in the basin freeze, the man in shorts and a vest laughed out loud, "Hahahaha..." What's so difficult about this? It's just making ice. After all, he is a science student. He was one of the top three in chemistry, if not the first in the class. People

who don't know him think he is crazy.

It is the hottest month of the year. In previous years, the heat has never been so unbearable. This year, Cao Xiangnan feels that the heat is really unbearable.

Several children in the family have developed prickly heat to varying degrees. Xiaobao'er is in the worst condition. He has developed prickly heat all over his body in one night. It's not okay to make a fuss. I went to Dr. Luo to get some medicine and boiled a large pot of water for the children at home to soak. After taking the medicinal bath, they are feeling better now.

Only Lele didn't have prickly heat. He didn't even sweat much in this weather. Cao Xiangnan found this strange. He was so hot inside that his clothes were always wet. He wanted to take off all his clothes and run naked.

At this moment, Cao Xiangnan remembered about making ice. In this era, ice was not so common. Only the palace and the houses of the royal descendants, nobles and wealthy families had ice cellars to store ice. Ordinary people were satisfied with having a meal. They didn't want to go out and get these things. Even if they wanted to, they didn't have the spare money to do these things.

There were ice sellers outside, but the price was very expensive. Ordinary people couldn't afford ice at all, let alone spend money to buy ice.

Even with refrigerators, no one has thought of making ice. When Cao Xiangnan was in school and taking chemistry classes, he heard his chemistry teacher talk about making ice. All you need is saltpeter, which is as easy as drinking water.

When the ice was made, the children around him asked curiously, "Dad, what is this?"

"It's ice cubes, stored in the house to cool down, but you can't eat it, okay? If you want to eat smoothies, dad will make you something edible later, but you can't eat it if you store it in the house, okay? Remember what dad said?" Cao Xiangnan repeatedly emphasized that this ice was not edible, and frightened the children that if they ate the ice stored in the house, they would get intestinal problems.

"Dad, we'll remember it." The children nodded vigorously, afraid that their stomachs would really get holes and their intestines would rot after eating, so they covered their stomachs one by one, not even daring to reach out to touch.

Seeing that the threat worked, Cao Xiangnan smiled and nodded, very satisfied with the effect.

Seeing her husband scaring the kids, Qi Wanfeng just stood aside and laughed, knowing in his heart that there must be three-tenths of truth in what her husband said, and this ice must not be edible. It was such a hot day, and she didn't expect her husband to make ice with a few strange stones. Even he found it magical.

When he looked up, he saw the person standing there and laughing. Their eyes met. Cao Xiangnan grinned, revealing a mouthful of white teeth, and stood up to talk to his wife about the principle of ice making and the role of saltpeter.

Thinking about the function of saltpeter, he remembered that saltpeter has another function, which is to make explosives.

But that thing does not belong to this era, and it is too lethal and destructive. After thinking about it, Cao Xiangnan still shook off this idea in his mind.

"Hmm?" Qi Wanfeng saw that her husband had a look on his face, not knowing what he was thinking, and looked at him with confusion in his eyes.

"Nothing." Cao Xiangnan grinned, and seeing that the children were all looking at the ice and didn't notice them, he went over and kissed his wife.

Qi Wanfeng glared at her husband, with a smile on his lips, and he didn't seem angry.

Cao Xiangnan stretched out his fingers to hook his wife's fingers, and his heart was happy. Sure enough, life with a wife is different, and every day is sweet.

After dinner, the water in the jar also froze.

"Okay, I'll make you a red bean smoothie or a milk smoothie. What flavor do you like?" There were various small bowls on the table. Cao Xiangnan crushed the ice into smoothies, some with red bean flavor and some with milk flavor. He then washed some fresh fruits, cut them into granules, and scooped them on the smoothies. A cup of smoothies was ready.

The children gathered around and shouted and jumped, asking for some.

"Dad, I want some." "Daddy, I want some.

" "Okay, don't worry, don't worry, everyone will have some." Cups of smoothies were quickly made. Cao Xiangnan didn't dare to give the children too much, so each of them had a small bowl, which was only half full.

It happened that the family had finished dinner at this time, and Sun Bailian brought a few children from his family here.

Seeing the people coming over, Cao Xiangnan smiled and said, "You came at the right time."

"Xiangnan, what are you doing?" Sun Bailian saw the things on the table, and didn't know what Cao Xiangnan was doing, so she asked curiously. Jingbao ran over and asked, "Uncle Xiangnan, what is this?"

"I'm making delicious food. This one has red bean flavor, and this one has milk flavor. Jingbao, Kangkang, what flavor do you want?" Cao Xiangnan pointed at the food on the table and introduced them one by one, asking the two children who came later what flavor they wanted.

"Hmm..." Jingbao was thinking about it, and wanted all of them.

Kangkang took a look and said he wanted the red bean flavor, and Jingbao followed his brother and asked for the same.

Qi Wanfeng saw Sun Bailian holding the three children and clapped his hands. The children saw him and climbed over to him to hold them, and he took them. The two brothers stood together and talked. Sun Bailian asked Cao Xiangnan what he was doing.

"Well, that's it. My husband said it was smoothies. Do you want to try it?" Qi Wanfeng said.

Sun Bailian was also curious, nodded and said yes, and ordered a red bean flavor.

"Everyone go sit over there. Only those who sit well can eat." After the smoothies were ready, Cao Xiangnan asked the children who were gathered around to sit at the stone table over there. "Whoever sits down first will eat first." He shouted.

"Go and sit down."

"Go, go."

Several children screamed and rushed over there, each finding a seat to sit down. Xiao Baoer didn't even know what his brothers were running for, and followed them and made a noise.

Xiangzi carried little Adi to the chair, and then walked over to pull Lele over, and carried him to the seat. When everyone sat down, there was no seat left, so Xiangzi stood behind Xiaobaoer and watched Adi, afraid that Adi would not sit well.

Lele who was carried up: Brother is not a foodie, brother was just dragged here...

"Okay, everyone is seated, right?" Cao Xiangnan took a look and put all the bowls on the tray. Qi Wanfeng walked over and said, "Husband, I'll take it over." He asked his wife to take it over, and then made a few more bowls, and everyone in the family had one. It

was so comfortable to eat something cool and icy in this weather.

Later, Cao Xiangnan made a few more copies and asked Liu Yuan to send one copy to Yipinzhai and another copy to Luo's Clinic. Doctor Luo also had two grandchildren there, so when he came back, he picked up Aning and Xuanxuan to come over.

Cao Xiangnan would not forget to send any good things to Doctor Luo at home. After all, when someone in the family was not feeling well, they would often go to him to trouble him. They had a good relationship with him.

Luo Rongheng asked someone to find Tian Qi, and Doctor Luo made it into medicine powder. This thing was very useful.

Especially in this era, it was a good idea to have a good relationship with the doctor.

"Send it over quickly." Otherwise, the weather would melt quickly, Cao Xiangnan ordered.

"Yes, don't worry, sir, I'll send it over now." The two brothers of the Liu family got on the carriage, one drove the carriage, and the other carefully carried a basket to deliver food. When he came back, he not only brought back Aning and Xuanxuan, but also the two grandchildren from the Luo Family Clinic. As

soon as the boy went out, Luo Rongheng followed him.

Seeing the good things Cao Xiangnan had made, Luo Rongheng was moved. He grabbed the boy's neck and pulled him to a corner to show his affection, "You are really good, you made all these things."

Otherwise, he would not have followed Cao Xiangnan to this place as soon as he saw this thing. He also wanted to see how this boy made this smoothie. He didn't believe that Cao Xiangnan would have an ice cellar at home to store ice.

There is no ice cellar in his clinic. In the past, he was rarely at home. When he came back once a year, it was winter. Who would think of setting up this at home? But now he is not going out to do business, but staying at home. The weather is so hot that it is unbearable. In just a moment, the clothes on his back are soaked.

"Nowhere, nowhere, they are all small things." Cao Xiangnan laughed and said, "Brother Rong, when you go back later, bring some ice back and put it in the house to keep cool." It will be easier to sleep at night. Otherwise, there is not even an electric fan here, and it is impossible to sleep at all.

"Thank you, brother." Luo Rongheng was not polite either. He was very satisfied that this kid was so considerate without him asking.

But if it's just one day, what will we do in the future? He held the man tightly.

Their eyes met. He didn't know Luo Rongheng had body odor when he was being held together by two sweaty men. He almost fainted from the odor. Cao Xiangnan smiled foolishly while holding his breath, and said, "Brother, you can ask someone to come to my house at this time every day. I'll keep it for you."

But he didn't forget to remind him that this ice can't be eaten directly, and you have to prepare it separately if you want to eat it.

"I'll remember that." Luo Rongheng finally let go, patted Cao Xiangnan's shoulders twice, and said generously, "Brother, if there is anything you like here, just tell me and I'll have someone send it to you." "

Brother, we are brothers, why should we care about these things? Brother Rong, just tell me how much you want in advance, and I'll prepare it for you." Saltpeter can be recycled, just put a basin of water and throw the saltpeter in. Only making ice for eating requires an additional process, which is a bit more troublesome. Making ice for use is a piece of cake. It

is true that he and Luo Rongheng have a good relationship, otherwise he would not have let Luo Rongheng know that he can make ice. Cao Xiangnan also understands the principle that a man is innocent but guilty of possessing a jade.

After sending the guests away, it was dark.

When Luo Rongheng left, he took two large buckets of ice and went back with satisfaction. He ordered two buckets of ice every day. He didn't want to take advantage of his brother, so he asked someone to send a box of bird's nests.

Two buckets of ice in exchange for a box of bird's nests, this was definitely a bargain for him.

The next morning, Zhao the shopkeeper brought people to his house. Cao Xiangnan didn't think it was strange to see Zhao the shopkeeper come, because he knew what he was here for.

Without waiting for Zhao the shopkeeper to speak, he took out the recipe for making ice and gave it to Zhao the shopkeeper. He sternly reminded him that this ice was not edible, because he was afraid that someone would be poisoned if they ate it by mistake. As for the recipe for edible ice, he also gave it to him.

When Zhao the shopkeeper left, he left a banknote here. As for the profits in the future, he would get 50% of them later. This is a very profitable business. It is a steady profit. I believe that Fang Ziye has the ability to make money at this time. He can just sit and wait to collect the money.

"Goodbye, Brother Zhao!" Cao Xiangnan sent him out the door with a smile on his face. This is his God of Wealth.

The God of Wealth waved his hand.
