After the sick and weak beauty flirted, the king of war and God of War fell

But before she let him go, he and Luo Jingyao were quickly offered marriage, and they got married soon after.

He must be angry with her. He doesn't really have feelings for Luo Jingyao.

But now?Can't she give up yet?

However, she also wanted this kind of feeling, his love, care and cherishment.

"We will come out more in the future." Luo Jingyao wore furry gloves on her hands that looked like cat paws, with embroidered pink flesh pads. She personally pushed An Wang's wheelchair on the street and looked at Seeing the bustling crowd with smiles on their faces, she also smiled happily.

This prosperous scene is a symbol of whether a country is strong and wealthy.

"Okay, let's find a place to sit." In the cold winter months, he was afraid of freezing the little girl behind him.

"Are you cold? Let's go to the Zhixiao Building in front." Luo Jingyao took off her gloves, touched Wang An's hand, tested the temperature of Wang An, and felt the dry heat on Wang An's hand , she smiled mischievously.

Do not admit that you have eaten tofu.

King An gave her a doting look. This is what she should look like at her age. That mature and steady look is not suitable for a little girl.

"I'm not cold." When the Tatars were guarding the country at the border, in winter, their cattle and sheep had no grass to eat, and countless people starved to death and froze to death. This caused them to lose a lot of property, and it was a problem for them to have enough food. They can only rely on robbing our country's rich land and harassing the people on our border.

Winter is the coldest season every year, and it is also the season when they fight the most. Most of the time, they have no time to return to the city and lie in ambush on the ice and snow. The cold is so cold that it penetrates their bones, and their hands and feet are soaked in hot water. When he was pregnant, he always felt that it would explode accidentally. It was really painful and swollen, but it was bearable. The only thing that was unbearable was the pain and itching, but it couldn't be solved.

King An looked at the children not far away. They were laughing and joking so happily, but they were so cold that they couldn't hold their hands tightly and they were clasping each other in their sleeves. He lowered his eyes.

There is still a long way to go before the people have enough food and clothing...

"I didn't think of it before. Then it got cold and we burned the ground dragon again. We warmed up, so naturally we couldn't remember it. Now I think of it again, but now I can't do it. It's cold and the ground is frozen. I can only wait for spring to get warmer and make it as soon as possible. The people will have a better time in the winter next year." Seeing the pain in Wang An's eyes, Luo Jingyao decided to help.
"What is it?" Although he has been to that world, he is trapped in that world and cannot go out and walk around. Although the little girl is said to be in a high position in that hidden family, they usually go out to experience it. Naturally you will see more.

"Fire kang, coal." Luo Jingyao only had two words, but King An felt it was not simple.

Turn the wheelchair immediately.

"We are going back home. Please tell me in detail." There is no detailed statistics on how many people freeze to death every year, but he thinks it will be no less, especially in disaster years.

"Okay." The two of them, who had just left the mansion, turned around and returned to Prince An's Mansion. They sat in the study, which was as warm as ever. They could no longer wear their cotton-padded coats and sat at the desk in thin spring shirts.

Luo Jingyao explained while drawing.

"Let's talk about the fire kang first. The fire kang can replace the existence of the bed. Our bed is indeed cool to sleep in in the summer, but it is a bit cold in the winter. Even if we burn the earth dragon, the bed will not be warm. We usually still use it. Come to Yubozi to warm the bed, but the fire pit is different. It is hollow inside, and you can burn firewood and charcoal in it. Even grass roots and leaves from the mountains and fields on the roadside can be gathered and filled in the fire pit. Inside..." Luo Jingyao explained while drawing, writing and drawing on the paper the dimensions of the fire kang she had seen and the materials used on it.

After Wang An looked at it in detail, his eyes became brighter and brighter, and his heart was stirring in his chest.

If there is a fire kang, no one will freeze to death in winter in the future.This thing can not only be used by the common people, but also by most households in the capital.The troops stationed at the border can set up this kind of fire kang as long as they are in the house, in addition to their camps.

Luo Jingyao waited until King An had almost digested it before she started talking about coal.

"The coal is not the silver charcoal we use. The silver charcoal we use is made from a wood material. The coal I am talking about is the coal commonly used by servants of wealthy families. It is the black black I don’t know how common this kind of lump is. There is still a layer of residue in the ash left after it is burned. We don’t need to dump it. We can keep it and fill it in the fire kang in winter. Or mix water with a small amount of red soil to make mud blocks of the same size and thickness. After drying in the sun, they can be used again..."

"I know about coal, but few people use it. Even the servants of wealthy families will use the inferior charcoal, not coal."

Luo Jingyao was shocked, and the shock in her eyes made King An couldn't help laughing: "You probably don't use it very much, no matter in the past life or this life. When this thing could be ignited at first, everyone was happy, but it didn't take long for people to use this thing to light it." There are not a few people who have done it. In the end, although the court will not strictly prohibit the people from using it, the people spontaneously stop using it." Unless forced to do so.

"I know this. Carbon monoxide is produced when coal is burned. Carbon monoxide is a poisonous gas. If the coal is not fully burned, it may cause carbon monoxide poisoning. The accident you mentioned should be carbon monoxide poisoning caused by poor ventilation and the equipment used for it. It should be incorrect.”

Luo Jingyao said and started to draw a few pictures of stoves. These were the stoves she saw used by farmers when she traveled around with the masters in her previous life. She found them very novel and went to refer to them, and later bought them. Got one to study.

"The silver wire charcoal we use is fired high-quality wood charcoal. There is no smoke when placed in the stove. And I know that most people use a brazier, the kind that is open, right? In that case, In addition, if the carbon we use is not the kind of carbon we use, but coal, the smoke will be very strong and it will naturally be poisonous." Luo Jingyao said while Wang An nodded.

Luo Jingyao was so cute by Prince An.

She didn't know what this man was like on the battlefield. She had never seen him before, but now, she thought he was okay. He was not as cold as he was said to be. He was also a noble ordinary person.

"What is this?" Wang An asked, pointing to the arm-thick pipe connected to the stove.
