Wenshen really slept well after returning from Zuixianlou. The next morning, in the study, Wenshen used his laptop to watch the process and craftsmanship of steelmaking, while eating the breakfast made by Wang Xiu. The soothing music slowly flowed out of the computer speaker. Wang Xiu and Cecilia Cheung leaned against the door frame of the study, watching and listening. The comfort and tranquility that had never been before floated back and forth between the three of them.

"Wang Xiu, I haven't gone home some time ago to see your father." Wen Shenbai asked bored and lazy.

"I'm back. I gave my mother the bag of laundry detergent you gave me. My mother was so happy, saying that she had never washed her clothes so clean." Thinking of her mother's excitement, Wang Xiu said happily.

Cecilia Cheung continued: "No, sir, the piece of soap you gave me was taken away by my sister when I got home. My father said, sir, sir, sir, are so capable, and even told me to marry you." After that, Cecilia Cheung suddenly felt embarrassed and turned her head and ran to her room.

Wang Xiu looked at Wenshen, then lowered his head, played with the corners of his clothes with both hands, and asked softly: "Sir, are you going to marry Sister Zhang?"

"What do you mean by this?" Wenshen thought depressedly. Of course, Wenshen is not a fool. You can tell what the two of them mean, or what their father mean at a glance.

"You are all still young, let's talk about this later." Wen Shen responded.

"What a small one, it's the same age as me, and there are two kids in the village." After Wang Xiu said that, he felt as if he had said the wrong thing. He glanced at Wen Shen, turned his head and ran back to his room.

Wen Shen was stunned for a moment, shook his head, and thought to himself: "Does it really matter that I should find a wife? But why do I always feel unrealistic in the Song Dynasty? Forget it, I don't want this anymore."

In the afternoon, Manager Li brought a young man and a young man to Wen's house. After a greeting, the three of them sat down.

Wenshen looked at this young boy Li Deqing. He looked like he was sixteen or seventeen years old. If he were in modern times, he would look like a junior high school. He wore a whip hat on his head, a gray robe and a cloth strap around his waist. His face was a little dark, but his eyes were glancing around, looking very aura.

"Shopkeeper Li, this is your son Li Deqing."

"That's right, Deqing, I've come here to meet Mr. Wen."

"Hello Mr. Wen." Li Deqing gave Wen Shen a teacher's gift.

"Okay, Deqing, right? I have heard that you like to do strange things every day. Can you tell me about it?" Wenshen asked.

"Sir, I've made something very interesting recently." Li Deqing said, taking out two things from his sleeve. Then, Li Deqing put a bamboo piece with two holes in the middle on a wooden stick that looked like a small fork. It happened to be one hole and one fork, and then Li Deqing used both hands to squeeze the wooden sticks. Then he saw the bamboo piece flying into the air with a "whisper" one.

"Isn't this the bamboo dragonfly I often played with when I was a child?" Wen Shen curled his lips and thought to himself.

"Deqing, do you know why that bamboo piece flew into the air?" Wenshen asked.

"Uh... Well..., I think..., I don't know." Li Deqing held it in for a long time, and didn't know. Beside, Manager Li looked at his son with a look of regret.

"Do you know why the palm-leaf fan is windy in one fan?" Wenshen asked again.

"I don't know!" Li Deqing answered simply this time.

"Want to know?"

"think!"

"Because, there is air around us. Although the air cannot be seen or touched, it really exists. It is like there will be wind when fanning hard, and the wind is caused by the flow of air. Do you understand?" Wen Shen asked.

"Oh, I understand a little." Li Deqing scratched his head and whispered.

"We live in the air, just like fish living in the water. We cannot feel the air, just like fish cannot feel the water.

"A person can breathe in one breath, is the air here just air?" Li Deqing said.

"It can be said that people breathe because they need oxygen in the air." Wen Shen said.

"Oxygen, what is it?" Li Deqing asked to the end.

"Uh, you will know after reading this book." Wen Shen finished speaking, returned to the study, picked up the general primary school textbook "Nature", returned to the living room, and threw it to Liu Deqing.

After Li Deqing got the book, he slowly began to browse it. Then he gradually became fascinated and thought to himself: "So this is how it is. The world is so wonderful."

When Manager Li saw his son, he was fascinated by reading books. He asked, "Mr. Wen, when will the coking plant you mentioned yesterday go on?"

"Tomorrow, I'll invite Manager Li today to find a few kilnmakers. I'll start digging kilns and coking tomorrow." Wenshen replied.

"Okay, I'll make arrangements now. The child will be with Mr. Wen first. After reading the book, he will let him go home by himself." said Manager Li.

...

Since Li Deqing read the book "Nature", he often came to Wenshen to read it. It is said that Li Deqing is really smart. He learns everything quickly by learning from one example and is especially interested in chemistry and interest. Wenshen will explain it to him if he has time. Not many Wenshen can meet it. Fortunately, there are Baidu masters.

...

Manager Li quickly recruited three kiln workers and more than a dozen assistants. The next day, on a hillside near the cement plant, under the command of three kiln workers, dozens of cement workers and more than a dozen assistants quickly dug up all the kilns and reinforced them with cement and blue bricks.

Coking is actually very simple, it is to put the coal in a sealed space and heat it until it becomes coking. The most important thing about coking is to prevent air from entering the kiln.

The new kiln was first heated and removed from wet. Then, under Wenshen's command, the coal was filled into the kiln pit and sealed with cement and blue bricks.

After a night of refining and a morning of cooling, the next afternoon, Magistrate Lin and others came to the kiln early to see what Wenshen said about coke.

"Mr. Wen, are you here to promote the opening of the kiln?" County Magistrate Lin smiled.

"With Magistrate Lin here, how can I announce it? It's better for magistrate Lin to come." Wen Shen said politely.

"Yes, County Magistrate Lin is coming," everyone continued.

Seeing this, Lin was very happy and said, "Then, I will promote the opening of the kiln."

At the order of Magistrate Lin, several assistants standing at the kiln entrance smashed the blue bricks sealing the kiln with sledgehammers. Then, the assistants entered the kiln and lifted the coke out of the kiln in bamboo baskets.

When everyone saw the first basket of coke coming out, they surrounded them.

"This coke is very light." County Magistrate Lin picked up a piece of coke, weighed it, and said.

Wen Shen laughed without saying a word, and asked the helper to bring a brazier. He picked up a few pieces of coke and threw it into the brazier. After a while, the coke burned in the brazier.

Magistrate Lin walked around the brazier for a few times. Suddenly, he shouted loudly: "Okay, okay, okay!"

Then he said: "This coke is light, big, smokeless, and flammable, which is a bit better than the best charcoal. It is really a good thing. A small kiln turns almost useless coal into the best coke. Mr. Wen, I admire it very much."

"It's really a good thing, Mr. Wen is really talented. No, I also dug a kiln to make coke when I go back." Everyone thought.
