Seeing the expression of this eccentric sister, Li Yuan laughed and stroked his beard.

"Okay, it's because the brother is wrong, but little sister... That kid Cheng Sanlang is not a bad person, at most he has a bad temper, don't pay attention to him.

If there is any misunderstanding between you, let me know. Back to the old man personally shot, help you beat him severely. "

"..." The eldest princess Tong An looked at the smiling elder brother, and inside and outside the words, she clearly showed a posture of defending the kid. Li Ke hurriedly answered first.

"Father, Brother Chubi made a peat-burning stove and dedicated it to my father."

Li Ji next to him was immediately amused, with a surprised expression on his face, he exclaimed in a low voice.

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

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

"I said Li Qing, Hugh is talking nonsense. There is no stove that can't burn peat."

Seeing that these three elders had a hippie smile without the slightest bit of formality, Cheng Chubi felt terrified in his heart.

You dare to insult me ​​like this, do you know not to bully the poor, do you know Hedong in thirty years, and Hexi in thirty years.

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

Cheng Chubi, who was madly complaining in his heart, could only force a smile.

"But this stove presented by my little nephew can make the smoke from the peat no longer smoke to the person who is warming."

"In addition, only one such stove is needed to make such a large room as warm as spring, and the price is very low."

When Li Shimin heard this, he finally put away his scornful smile, and saw his own sons Li Ke and Fang Jun beside him.

I couldn't help being curious, and when I came out of the house, I saw the iron stove, the pottery smoke pipe, and the two baskets of peat used for trial combustion.

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

Compared with the two copper carbon stoves, this very rough-looking thing is not as big as the half-human-high copper carbon stove.

Li Shimin swept his gaze, pointed to the house next to Chang'an City and the surrounding area where the sand table was placed.

"Since you've all brought it into the palace, let's try it. Well, there is no fire in the room next to it. You should put the stove there."

The disapproval attitude of the three elders made Cheng Chubi, the inventor of the iron stove, very unhappy.

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

Cheng Chubi took it upon himself to puncture a high window so that the pottery pipe could be stretched out of the house.

#####

When the hearth of the iron stove began to glow faintly, the kettle on top of it was still spitting out white steam.

Li Shimin, Li Ji, and Ashnadul surrounded the iron stove.

Tsk tsk looked at this simple and rough iron stove in amazement.

The billowing thick 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, but Cheng Chubi quickly stepped forward in fright.

"Uncle, don't do it, just look at it, this thing is too hot."

Gu Xiu

"It's hot even if it's so far away?" Li Ji looked at the iron plate that protruded about a foot from the bottom of the kettle in all directions, and couldn't help but feel a little disbelieving.

Cheng Chubi rolled his eyes, and simply started directly, picked up the kettle above the iron stove, and poured some water towards the edge.

Hearing a chirp and seeing the white air churning, Li Shimin couldn't help grinning, raised his head, and wiped the fine sweat from his forehead.

"Nephew Chubi, why does this feel so much warmer than charcoal fire?"

Cheng Chubi left his Majesty the Emperor of the Tang Dynasty, who had no foundation in physics, and explained it in the most simple language.

"That's because the coal is two to three times as calorific as firewood, and they burn at nearly twice the maximum temperature."

"Plus 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 indoor air warm..."

Li Shimin looked at Cheng Chubi, who was talking about Kankan, and he was completely numb to how much knowledge this guy could know.

But he was still curious, how could this kid think about playing with this stuff again?

"Nephew, why didn't you get such a good thing out earlier?"

Li Ke, hey hey, is an excellent spy and meticulous work who was placed beside brother Chubi by his own father.

At this time, he needs to stand up bravely and expose brother Chubi's diligent and thrifty housekeeping.

"Father, that's because Brother Chubi is worried about the heating problems of the teachers and students of Cheng's University, maybe he thinks charcoal is too expensive, so..."

Having said that, UU reading www. uukanshu.com saw Brother Chubi's dangerous eyes staring at him, Li Ke shut his mouth very interestingly.

But the information that should be leaked is enough to make the three big bosses dumbfounded.

Li Ji, the delinquent elder who likes to mock and tease the younger generation the most, slapped Cheng Chubi on the shoulder.

"Cheng Saburo, Cheng Saburo, what kind of poverty is your kid? You are so careful all day long, aren't you tired?"

Cheng Chubi snorted unhappily, and raised his neck to mean something authentic.

"Then what should we do? Don't say that this year, the salary for the first half of next year is gone. If you don't plan carefully, you can't drink the northwest wind to satisfy your hunger, right?"

Instantly, the sound of puffs rose and fell in the house, and Cheng Chubi's seven orifices could be heard smoking.

I really want to pick up that pot of boiling water and pour it over the conscience of these guys, and ask them if their conscience will hurt?

Li Ke was so happy that he wanted to clap his hands, but his fingers rubbed against the iron stove, causing the guy to scream strangely and keep shaking his hands.

Seeing this scene, Cheng Chubi finally laughed out loud.

"Brother, you can't be so exaggerated when you hear that I'm diligent and thrifty in keeping the house, brother Yu?"

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

Ashnadur, who was on the side, observed everything in front of him secretly with a smile. He didn't enter the Tang Dynasty for a long time.

I only came to the Tang Dynasty last year, and after that, I got the attention of His Majesty, and even married a princess, His Royal Highness, 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 laughing.

But he had already heard about it, and heard a lot of things about this Cheng Saburo.

Even his wife once told Ashnadul that in the circle of officials in the Tang Dynasty, it is best not to offend the Cheng family.
