Indeed, Ying Zheng discovered a mystery of this furnace.

That is, the burning furnace does not seem to need to add any fuel to it.

For a while, Ying Zheng couldn't help but show a look of surprise, and he couldn't help but say with emotion.

"This stove is really good, but I don't know what the fuel in it is, it can be so durable, burn-resistant, and ......."

As he spoke, Ying Zheng stretched out his hand and tested the temperature near the stove.

Suddenly, Ying Zheng only felt a wave of hot air on his palm, seeing this situation, Ying Zheng couldn't help but sigh with emotion, and continued to face Li Si on the side, opening his mouth and saying.

"The fire in this furnace is quite hot, but I don't know what is burning in it......"

Ying Zheng said with emotion, but Li Si on the side gathered his eyes on the chimney on the side of the stove, and then said to Ying Zheng.

"Your Majesty, please look here, this stove, there is also a special feature, its chimney can be smoked, so that there is no smoke in the house, I have to say, this design, quite wonderful!"

"yes!"

Seeing this, Ying Zheng couldn't help but look towards the chimney.

This chimney is made of brass.

Seeing it, Ying Zheng couldn't help but say with emotion.

"If all the people in the world can have such a stove that can be used for heating, then no one in Daqin will die because of the cold......

"Your Majesty, it's not too difficult for the people to use this stove!"

When Li Si heard this, he looked at the copper furnace and said to Ying Zheng on the side.

"This stove is made of copper, I think it should be for aesthetic reasons, after all, black iron is placed indoors, it is not very elegant, if it is an ordinary people's stove at home, then there is no need to care about these things!"

"So, ordinary people can buy an iron stove for heating!"

"And the iron stove, naturally, the price will be quite cheap!"

Yes, iron stoves compared to copper stoves.

The price is definitely a lot cheaper.

After all, iron is such a thing.

How much and how much to have.

And on the other hand, the copper thing.

So far, there are not too many copper mines in China.

Huaxia itself is a copper-poor country.

For the present, the cost of using iron is definitely lower than that of copper.

I saw it, and Ying Zheng's eyes lit up.

But then.

Ying Zheng sighed again, smiled awkwardly at Li Si, and said.

"Li Si, you and I are confused!"

"Your Majesty, what are you?"

Li Si didn't know why, and looked at Ying Zheng in surprise.

I don't understand why Ying Zheng would say that he was confused with himself.

At this time.

Ying Zheng, but he sighed and said the reason, only to see that Ying Zheng pointed to the stove and asked Li Si with a heavy face.

"Li Si, I ask you, what is missing from this furnace in my Great Qin? Or is there fuel burning in the stove? ”

"This ......"

A word from Win Zheng.

In an instant, Li Si woke up.

Yes, at the moment of Daqin, it seems that there is no shortage of stoves at all.

Ordinary people's homes do not have stoves.

Light on the open space, light firewood, can also provide a family for heating.

But the current Great Qin.

Here's the problem.

There wasn't enough firewood to burn.

So, at this moment, he and Ying Zheng are here, arguing about the issue of the stove.

It's just the opposite of the actual problem.

For a moment, Li Si's face sank.

Just as Li Si was thinking about how to talk.

Outside, a sound of footsteps came in, and then, I only saw Xiao He, who strode in, and behind him, Xiao Er, who was holding hot pot and dishes on one side.

But I saw that after Xiao He came in.

First, he commanded Xiao Er to take out a tongs from a bamboo basket, and then opened the lid on the stove, revealing the burning things inside the stove.

I saw that inside the furnace, what was burning, was a round, round shape, with many holes on it.

At this time, when he saw Xiao Er, he hurriedly took out all the round black carbons burning in the stove, and put the bottom piece, which was already burning with white black charcoal, into the bamboo basket.

Then, with tongs, all the remaining coals are reloaded into the furnace in the original order.

At this time, this little two was in the surprised eyes of Ying Zheng and Li Si.

Take out a piece of new charcoal from the bamboo basket, and then put the coal on the hole in the honeycomb coal in the furnace.

This scene is the shock of Ying Zheng's face.

He didn't expect it.

In this world, there is such an exquisite design.

At this time, Xiao He was commanding people to put the hot pot on the stove, and then, Chao Yingzheng and Li Si were the two people.

"Your Majesty, Prime Minister, you two, please have dinner!"

"No hurry, no hurry!"

Ying Zheng shook his head again and again, with a look of curiosity on his face, he asked Xiao He in front of him.

"What is this burning?"

"How long can a piece burn?"

"What is the price of this piece of charcoal?"

"Your Majesty, are you interested in this?"

When Xiao He heard this, he couldn't help but show surprise, he pointed to the copper furnace, and then asked Ying Zheng.

I only saw Li Si, and said impatiently.

"Your Majesty is indeed a little curious about this, and you will tell what you know, one by one!"

"No!"

Hearing this, Xiao He didn't dare to be the slightest slack, and he said truthfully.

"Your Majesty, this furnace is actually the invention of the Nineteenth Prince, as for what is burning inside? I don't know, but it seems to have been dug out of the ground......"

"Then, after the mold is processed, this thing is formed!"

"But then again, this thing is very resistant to burning, one piece can burn for an hour or two, at the end of the day, at most five or six pieces of carbon, and at night the hole outside the furnace fire is sealed, replaced with two pieces of new carbon, can make this fire-resistant, not extinguished overnight!"

Xiao He won the government and talked eloquently.

Hear here.

I can't help but win the government, I feel that this honeycomb coal is a good thing.

Ethical, its light weight.

Secondly.

It is also used in saving.

At the end of the day, it's just a few pieces.

It's so easy to do.

You know, if it's firewood.

It takes a moment, someone is watching, and then going to add firewood.

And now, this honeycomb coal, there is no such thing.

I saw Ying Zheng continue to ask.

"And what about the price of this item?"

"The price, the minister is not very clear......"

Xiao He shook his head.

He didn't know anything about this matter, and when he heard this, Ying Zheng looked at Li Si on the side.

I saw it, Li Si muttered in a low voice.

"Since this thing is mined from the ground, it is probably a worthless thing, and the cost should not be too high, right?"
