Dressed as cannon fodder and vowing to kick the heroine’s head off

But Xiao Chenyi didn't know that the temperature of the earth cannot be lowered just because you want it to.

The only way for humans to fight against high temperatures is to rely on their own wisdom to better protect themselves.

For example, building ventilated houses, using shading and insulation materials, and using courtyards and pools to increase air humidity and reduce temperature.

Wear light and breathable clothes, such as silk and linen. These fabrics are breathable, can make the body feel cooler, and can relieve the heat to a certain extent.

In terms of diet, try to choose light and cool foods such as fruits, vegetables and herbal tea to help cool down and relieve heat.

If the imperial court benefits from it, it will build water conservancy facilities, such as Yunhe, wells, etc., which will not only ensure the residents' living water to a great extent, but also reduce the temperature of the surrounding environment through the development of water resources.

In addition, fans are the most common and only tool for cooling off that everyone, from the poor to the rich, can own.

Rich people would use some "ice cubes". They would store ice cubes in winter and use them to make cold food in summer. If the weather was too hot and there was enough ice cubes, they would put some in the room to cool it down.

The ancient method of making ice could only come from nature.

"Storing ice in winter", "storing ice in deep wells" and "making ice in icehouses" were the most commonly used methods. Later, "making ice with saltpeter" also appeared.

Since the topic came to this, Yun Xi had a detailed discussion with Xiao Chenyi.

Xiao Chenyi didn't expect Yun Xi to know so much, and the more they talked, the more excited they became, and they even talked about how to dig wells and develop canals in a regular manner. This is what Shu lacks the most at present.

Yun Xi also learned from Xiao Chenyi that "saltpeter ice making" has not yet appeared.

"Chen Yi, I know a way to make ice. It can make ice cubes quickly without spending a lot of money to buy ice storage."

As soon as Yun Xi finished speaking, Xiao Chenyi was surprised: "Make ice? Ice can be made?"

In his memory, ice was knocked down from the snowy mountains, transported over long distances, and sold to the capital. Because the journey was long and difficult, and a lot of it would melt and be damaged during the journey, the ice that was transported to the capital was simply astronomical in price.

Even so, it will still be sold out.

The weather is hot and unbearable. Who among the rich wants to suffer? Especially those who have elderly and children at home cannot bear the heat. Even if you want to compete with each other, you can't be cold!

Not to mention the palace.

Xiao Chenyi's eyes lit up.

If we can make ice by ourselves, how many problems can we solve? Wouldn’t it solve many of the problems of the people in Shu who are suffering from the scorching heat?

"Don't be too happy." Yun Xi smiled and said, "The raw materials needed to make ice cubes are not so easy to obtain."

Xiao Chenyi: "..."

A basin of cold water poured down on him. Xiao Chenyi felt chilled to the bone in an instant.

I knew it!

It’s not that easy!

If it was that easy, wouldn't others have done it long ago? No, it was my wife who had done it long ago.

He couldn't help but let out a bitter smile: "Then what else did you tell me?"

Yun Xi slapped him on the head: "Look at you! Can't you have a little confidence?"

"What raw materials?" Xiao Chenyi asked dejectedly.

If he had to go to the ends of the earth to find it, then he might as well give up. Digging wells and rivers would be more reliable.

"Saltpeter." Yun Xi said calmly.

Xiao Chenyi lowered his head and waited.

Yun Xi didn't say anything else for a long time. He couldn't help but look up: "Anything else?"

“That’s all!” Yun Xi spread her hands.

"Nothing else? Just saltpeter?" Xiao Chenyi's voice was raised in surprise.

"Yes, it's saltpeter." Yun Xi smiled mischievously.

"You...then why do you say it's difficult?" Xiao Chenyi was so surprised that he was almost speechless.

This girl, it's just saltpeter, why is she making it so mysterious? He thought it would take a lot of effort to find it. Saltpeter, he knows! He has a place to get it!

Yun Xi leaned over, stared into his ecstatic eyes, and said with certainty: "You have it!"

Xiao Chenyi nodded frantically: "Yes, I do! I have a lot!"

Yun Xi didn't expect such a big surprise. She raised her hand and patted his shoulder heavily: "Give me strength, brother!"

Xiao Chenyi's face darkened: "Who is your brother?"

Yun Xi said it so many times that he also knew that "geili" means very strong.

"Hehe, Your Majesty is awesome." Yun Xi was not afraid of his dark face at all.

Only his subordinates are afraid of this dark face. In fact, he is very easy to appease.

"But Your Majesty, how did you get saltpeter?" she asked curiously.

Xiao Chenyi was still unhappy with her address.

He stopped calling me brother and started calling me Prince.

Is it good to say "Prince"? Not intimate at all.

Yun Xi looked at the other person's face which was still obviously dark, thought about it, and understood. He was dissatisfied with her for not being intimate enough!

Don’t you understand humor?

This arrogant man! She just won't pamper him!

"Bring the saltpeter tomorrow and I'll try it." She stood up with a stern face.

Eh? Why did she leave? Is it so difficult to make her say something nice? She has done that before!

Xiao Chenyi was full of curiosity about how to make ice with saltpeter, so he would never let Yun Xi leave. He stood up, grabbed her hand, and pulled her into his arms: "Don't go, don't go. Talk to your husband and tell him how you did it."

Yun Xi asked with a stern face: "How can I say anything when you have a gloomy face? How can I still be in the mood to say anything?"

Although calling someone "husband" is not a big deal, she didn't expect it at all. How could he still look at her with a gloomy face?

This is when I need her help.

"I'm sorry, I'm sorry, it's my husband's fault." Xiao Chenyi admitted his mistake quickly in front of Yun Xi.

"As a husband, I shouldn't ask too much of you."

"Ah? What did you say?" Yun Xi refused, "What do you mean by asking too much of me? Am I not better than other women?"

"I was wrong, what I wanted to say was that I shouldn't have too high expectations for the way you address me. You are certainly the best woman, the best mother among all the best." Xiao Chenyi smiled in a flattering manner.

Yun Xi snorted: "If you do it again next time, I will never forgive you."

Xiao Chenyi's face was bitter again: "Can't you just call me husband? Or Ayi?"

Yun Xi looked at him in surprise: "Are you mentally ill?"

Xiao Chenyi's face suddenly darkened: "I asked you to call me more affectionately, am I mentally ill?"

Yun Xi chuckled: "No, you asked me to call you Ayi, Auntie, it's Auntie..."

The more she thought about it, the funnier it got, and her stomach hurt from laughing: "Xiao Chenyi, you still have such a habit."

Xiao Chenyi's face darkened again.

As a man, I don't like being called a woman.

Is Yun Xi looking down on him?

snort!

He wants to show him whether he is a man or not!

The evolution of events was rapid and abrupt.

After a while of making love, Yun Xi opened her eyes in confusion: How could he do this to me?
