Li Ke quickly replied.

"Father, Brother Chu Bi made a peat-burning stove and dedicated it to his father."

Li Ji, who was next to him, was immediately happy, with a surprised expression on his face, exaggerating in a low voice.

"Oh, this is the first time the old man has heard that there is a stove that can burn peat."

Li Shimin laughed out loud directly, holding his belly and pointing at Li Ji, a confidant who likes to joke with juniors the most.

"I said Li Qing, Hugh was so gibberish, where is there a stove that can't burn peat."

Seeing the hippie smiles of these three elders that were not at all straightforward, Cheng Chubi felt badly in his heart.

Do you dare to insult me ​​in this way, do you know that you don't know how to bully the young and poor?

Believe it or not, thirty years later, Lao Tzu will jump on the graves of the three of you.

Cheng Chubi, who was frantically complaining in his heart, could barely squeeze a smile.

"But the stove offered by my nephew can prevent the peat smoke from reaching the heating person."

"In addition, this kind of stove only needs one, which is enough to make such a big room warm like spring, and the price is very low."

When Li Shimin heard this, he finally put away his happy smile, and saw his own sons Li Ke and Fang Jun standing beside him to prove it.

I couldn't help being curious. After I came outside, I saw the iron stove, the ceramic pipes, and the two baskets of peat for trial burning.

Li Shimin couldn't help but subconsciously turned his head and glanced at the two huge copper-carbon furnaces in the house.

Compared with the two copper-based carbon furnaces, this very crudely shaped thing is not as big as the half-person tall copper-based carbon furnace.

Li Shimin glanced away, pointed to the house next to the sand table in Chang'an City and the surrounding area and ordered.

"Since you have all taken it into the palace, try it. Well, the room next to it just doesn't have a fire. You put this stove there."

The disapproving attitude of these three elders made Cheng Chubi, the inventor of the iron stove, very upset.

Under his command, the iron stove was quickly installed in that room.

Cheng Chubi personally punctured a window at that high place, allowing the ceramic pipe to reach outside.

#####

When the hearth of the iron stove began to faintly reddened, the kettle on the top still spit out white steam vigorously.

Li Shimin, Li Ji, and the Asnadul three surrounded the iron stove.

He looked at this simple and crude iron stove with wonder.

The billowing smoke was being drawn outside along the pipe, and there was no peculiar smell inside the house.

Li Shimin curiously wanted to reach out and touch the stretched edge of the iron stove, scared Cheng Chubi hurriedly stepped forward.

"Uncle don't want to do it, it's done, this thing is too hot."

"It's hot too far away?" Li Ji couldn't help being a little unbelieving when he looked at the iron slab that was almost a foot sticking out from the bottom of the kettle.

Cheng Chubi rolled his eyes, and simply moved his hands directly, picked up the kettle on the iron stove, and poured some water toward the edge.

Li Shimin couldn't help grinning when he heard a whistle and saw the white air surging up. He raised his head and wiped the fine sweat from his forehead.

"Nephew Chu Bi, how does this feel much warmer than carbon fire?"

Cheng Chubi, his Majesty the Emperor of the Tang Dynasty who had no physics foundation, explained it in the simplest language with restraint.

"That's because the heat of coal is two to three times that of firewood, and the maximum temperature at which they burn is almost doubled."

"In addition, this iron is a good conductor of heat, so the temperature generated by the burning of peat causes the iron stove to heat up.

In addition, there is water vapor in the room, which makes the air in the room warm..."

Li Shimin looked at Cheng Chubi who was eloquent. He was completely numb to the fact that this guy could understand so much knowledge.

But he was still very curious, why would this kid want to tinker with this stuff again?

"Nephew, why don't you get such a good thing out sooner?"

Li Ke happily, as an excellent spy who was placed next to Brother Chu Bi by his father and also a detailed work.

At this time, he needs to stand up bravely and expose Brother Chu Bi's diligent and thrifty housekeeping.

"Father, that's because Brother Chu Bi is worried about the heating problems of the teachers and students of Cheng University. Maybe you think charcoal is too expensive, so..."

When it came to this, Li Ke shut his mouth wittily when he saw the dangerous eyes from Brother Chu Bi.

But the leaked information was enough to make the three bigwigs look dumbfounded.

Li Ji, the bad elder who likes to mock and tease the younger generation the most, slapped Cheng Chubi's shoulder.

"Cheng Saburo, Cheng Saburo, what kind of poor is your kid? Chengri is so careful in his calculations. Aren't you tired?"

Cheng Chubi snorted unhappily, stubbing his neck and pointing inwardly.

"What should I do? Don't say that this year, the first half of next year will be gone. If you don't plan carefully, my nephew can't drink northwest wind to satisfy his hunger?

The sound of puffing in the room was one after another, and Cheng Chubi's seven orifices could be heard.

I really want to pick up the pot of boiling water and pour the conscience of these guys~lightnovelpub.net~ ask if their conscience hurts?

Li Ke was so happy that he wanted to clap his hands, but as a result he rubbed his fingers against the iron stove, causing the guy to make a strange cry and wave his hands repeatedly.

Seeing this scene, Cheng Chubi finally burst into laughter.

"Virtuous brother, you hear that Brother Yu, I am diligent and thrifty, and you can't commit such exaggeration to jump up and down with joy?"

"Brother Chubi, don't talk to me..." Li Ke blew on his burnt fingers and turned his head away with a black face.

Ashnadur on the side was observing everything in front of him secretly with a smile, he didn't have a long time in Tang Dynasty.

I only came to Datang last year, and later got the attention of his majesty, and even married a princess as his wife.

It can be considered that he has finally entered the noble circle of the Tang Dynasty. Although he is not familiar with Li Ke, who is jumping up and down, and Cheng Chubi, who is laughing and happy next to him.

But I have heard about it a long time ago, and heard a lot about Cheng Saburo.

Even his wife once told Ashnadur that it was best not to offend the Cheng family in the circle of officials in Datang.

That guy is notorious, but he is very favored by His Majesty, especially Cheng Saburo.

Li Shimin looked at it with a weird expression, and he was still pulling his face, until the defendant Ke'er burned his fingers to Cheng Saburo, who was in trouble.

He shook his head dumbfoundingly, this group of young people is really speechless.

But having said that, in order to save a little money, this kid actually came up with a good treasure that benefits the country and the people.

This made Li Shimin not knowing whether he should despise this kid for being too stingy, or whether he should be praised for his diligence and thrifty housekeeping.
