"Have you heard that Wangyou Bookstore has released a new book called "Practical Guide", which tells us how to make a stove for winter."

"I heard that I made one at my home yesterday, which is the honeycomb coal mentioned in the book. It is not sold in Chang'an City."

"You said, is this Practical Guide lying to us?"

"How is this "Practical Guide" written by His Highness the King of Han himself. How could he lie to us?"

"What..."

"There is news that the honeycomb coal mentioned by His Highness the King of Han has not yet entered the east and west cities of Chang'an."

"But before New Year's Eve, you should be able to buy it."

"Lunar New Year's eve?"

"How much does that cost?"

"I don't know this!"

On the afternoon of that day, on Chang'an Street, the emperor came out of plain clothes from the palace. When he walked here, he heard the people talking about the book "Practical Guide" of Wangyou Bookstore.

He had just finished watching Duan Lun and the craftsmen from the Ministry of Works were busy repairing the kang in the palace, and he thought about coming to Chang'an Street to take a look.

Unexpectedly, I heard people discussing the new books of Wangyou Bookstore.

Zhao Chen hasn't personally compiled a book for a long time, and this emperor knows it.

Suddenly, I heard that Zhao Chen compiled a new book called "Practical Guide", and the emperor was also very interested.

Fortunately, not far ahead, there is the location of Wangyou Bookstore.

Not long after the emperor left, he came to the door of Wangyou Bookstore.

This is the crowd at this door, which really makes the emperor not want to step forward.

This is crowded with people, just like going to the market.

Even in the east and west cities, there are not so many people!

"I have seen what many people look like." The emperor said to himself.

Turn around and go to Zhao Chen's mansion.

He had to ask Zhao Chen what the stoves and honeycomb coal that the people were talking about just now were.

It was already noon when I arrived at Zhao Chen's mansion.

The emperor felt that he had calculated the time and walked into Zhao's mansion and saw Zhao Chen's family having lunch.

The emperor is here, and he still needs to eat.

Even though Zhao Chen did not really welcome the emperor very much, he still did not show it in front of Ping An.

After eating and drinking, Li Ruoshuang took a safe nap, and Zhao Chen and the emperor were left in the living room.

"Boy Chen, how can you stop looking at me with such eyes!"

"I didn't come here to have a meal on purpose. I really want to ask you something." When the emperor said this, he felt that he had no confidence.

It was a coincidence that it was really a coincidence that it came when they were having dinner.

Zhao Chen didn't say anything, waiting for the emperor's eloquence.

"Today I asked the Ministry of Works to start repairing the kang. After leaving the court, I came out of the palace to take a look. On the way, I heard the people talking about you, "You wrote a book called "Practical Guide."

"I thought about buying one, but Wangyou Bookstore was overcrowded. I'm not here to come to you directly!" the emperor and Zhao Chen explained.

"If you want to read a book, just send someone to me to get it. You don't have to go there in person." Obviously, Zhao Chen didn't believe the emperor's explanation.

The emperor smiled awkwardly.

He looked at Zhao Chen and then said, "Actually, I am here, and I still want to ask you some things."

"For example, what kind of honeycomb coal is being discussed by the people of Chang'an? What is it?"

The emperor was very curious that what Zhao Chen wrote in the book "Practical Guide" was not sold in Chang'an.

Since you can't buy something, why did Zhao Chen write this thing?

Or, the thing I wrote will soon appear on the market.

The emperor has figured out the rules. As long as it is something Zhao Chen made, it will definitely have different responses.

It would be best for me to follow Zhao Chen's footsteps at the beginning.

This will bring more benefits.

"Look at that." Zhao Chen walked out of the living room and came to the corridor.

Pointing at the corner of the corridor, there was a row of black cylindrical things.

"What is this?" The emperor walked over and looked at it, and his face was full of confusion.

He saw this for the first time.

Not only is the darkness in the whole body, but there are holes the size of a little finger in the middle

It's really strange!

"Aren't you curious about what honeycomb coal is? That's it." Zhao Chen and the emperor explained.

“That’s it?”

"What's the purpose?" The emperor was still full of doubts.

Even if he knew that the strange thing in front of him was the legendary honeycomb coal, he didn't know what this thing was for.

"Next is the stove mentioned in the book, which is specially burning honeycomb coal."

"You can use this thing to cook."

"Although it can be roasted, it is not recommended, and it is prone to carbon dioxide poisoning."

"carbon dioxide?"

"Why is it another thing I have never heard of?" The emperor was confused.

I only learned yesterday that burning firewood caused death is carbon monoxide, but why did it become carbon dioxide again today?

"That doesn't matter. Please help me replace this honeycomb coal." Zhao Chen did not explain carbon dioxide to the emperor.

Instead, let the emperor help change the furnace

The emperor was also curious. Looking at the yellow flames in the stove, he didn't dare to reach out to try it directly.

Anyone who is not a fool knows that this stove can cook him directly.

"How do you do this?" the emperor hesitated for a moment before asking Zhao Chen.

He didn't want to ask Zhao Chen about it, but obviously if he didn't ask, he would have no idea how to do it.

"There are iron pliers next to it. They can be pinched into the hole and then come out." Zhao Chen stood aside and said leisurely.

It is a very comfortable thing to ask the emperor to help with his work.

Zhao Chen felt that he had to find an opportunity to enjoy it.

Otherwise, Old Li would come to him from time to time, which would be really annoying.

"Oh!" the emperor responded, and then carefully inserted the iron tongs into the stove.

The hot heat wave hit his face, fortunately it was far away, otherwise his beard would have been ignited.

After finally swapping out the coal balls in the stove, the emperor was covered in sweat.

"How long can such a honeycomb coal be burned?" The emperor sat aside, looking at the steaming coal balls on the ground.

"If it burns, of course it's very fast. There is a hole under the furnace that can control the inlet of air and the combustion time."

"Then what is this honeycomb coal made of, forest?" the emperor asked Zhao Chen again.

In fact, this is his most concerned issue.

In the morning, Wei Zheng said that he was worried that the people would go to the mountains and forests to cut down trees.

It not only embezzles the resources of the imperial court, but also may endanger the safety of the people.

The emperor was thinking at that time that he could not cut down trees or burn the kang for the winter.

Wouldn't it be even more wonderful?

It was not until just that when I saw the honeycomb coal, the emperor felt more anticipated.

How great would it be if this honeycomb coal was not made of forest trees?

"Actually, this thing was the predecessor of Lin Mu." Zhao Chen said, looking at the emperor.

When the emperor heard this, he was depressed.

You still have to use forests, so what is the difference between going up the mountain and chopping wood directly?

"But this forest, which was from hundreds of millions of years ago, was buried in the ground and turned into stone..."

"Hundreds of millions of years ago?"

"Buried in the ground?"

"It turned into a stone?"
