Datang: My identity as prince was exposed by Li Er

Du He and Cheng Chumo were shouting outside

"Iron bucket breathable detox fan……"

"Can remove charcoal poison……"

Ever since Du He saw from Li Yi, there was an exhaust pipe standing on the greenhouse.

He knew that an opportunity to make money had come.

Nowadays, every household in the Tang Dynasty burns charcoal.

But when burning charcoal, you have to open the window.

The autumn of the fourth year of Zhenguan was already filled with ice and snow. It goes without saying how cold the weather was.

So Du He first went to Cheng Chumo's house and easily swindled ten thousand dollars.

It's just a pity that the old gangster Cheng Yaojin defaulted on the bill.

But it doesn't matter.

If Du He and Cheng Chumo worked together, this business would still work, but there would definitely be fools who would fall for it.

So the two of them set their sights on the Xiao family's pair of fools.

Get ready for a big deal.

Xiao Rui and Xiao Kai walked out of Xiao Mansion with their hands behind their backs.

The two of them had righteous faces and shouted angrily:"In the important place of the capital, at the feet of the emperor, who dares to make such nonsense... Huh? Du He? Cheng Chumo?"

What happened to the son of the Duke?

Still fined!

Besides, the fathers of these two little things have never dealt with their own father, so they should be severely punished!

"You two disturbed the order of Chang'an, and you also resorted to fraud to fool the people. Do you think you are guilty?"

Xiao Rui said lightly.

Xiao Kai echoed:"That's right, do you know your guilt?

Du He chuckled and said,"Fake?"

Cheng Chumo scratched his head:"Why did we cheat?" Xiao

Rui pulled his neck and said:"Just now you were clearly shouting that the iron barrel is breathable and can expel carbon poison, right?" Du

He nodded:"Yes, Brother Xiao, does your home need to install an exhaust fan?""

Xiao Rui angrily yelled:"That's all nonsense! How to get rid of charcoal poison in the middle of winter? Do you want to open the window? Du

He shook his head firmly:"Isn't the heat gone when you open the window?" The thing we want to sell does not require opening the windows, it can provide warmth, and it can also emit charcoal gas."

Xiao Rui shook his head and listened, then squinted his eyes and shook his head lightly:"I don't believe it!

Xiao Kai agreed:"Yes!" Do not believe!

Du He shook his head and said,"If you don't believe it, forget it. Let's go find someone else."" He pulled Cheng Chumo to leave.

Xiao Rui still blocked the way with a righteous look on his face:"We are the official Jinwu Guards School Lieutenant. You have lied to others and you will have to pay a fine before you can leave! Even the son of the Duke needs to be fined! Otherwise, where would the vast world be at the feet of the emperor?"

Cheng Chumo rolled up his sleeves.

Xiao Rui and Xiao Kai glanced at each other:"Don't be afraid! If you dare, fight! Du

He smiled and rolled his eyes:"Believe it or not, let's try it. As long as what I just said can be achieved, will you buy it?"

Xiao Rui said:"Buy!" As long as you implement such a policy to benefit the people, it will be a contribution to all the people of the Tang Dynasty. We will buy it no matter how expensive it is! After all, the courageous hearts of us two brothers can still be seen by the sun and the moon.

Du He high-fived and said,"Okay!""

Obviously.

He and Cheng Chumo each performed their duties, one was a good guy and the other was a bad guy.

The two followed the Xiao brothers to the side room.

Xiao Kai followed Du He's request and made the iron skin.

Xiao Rui The craftsmen were called and a small round hole was opened in the roof.

Xiao Rui said angrily:"What are you doing? What to do if there is a hole in the roof and it rains and snows?"

Du He didn't explain.

Within a moment, Xiao Kai brought the iron sheet.

He molded it on the roof and then led it directly into the house.

The iron sheet was connected to the charcoal stove, and the smoke dispersed directly from the roof. Directly to the sky.

But the heat still radiated in the house.

The doors and windows were closed.

After a while, the room became warm.

Xiao Rui and Xiao Kai looked at Du He and Cheng Chumo in confusion, and said in confusion:"What next?

Du He spread his hands and said,"What else?" Oh, and then it's time for you to pay."

Xiao Rui was angry.

"What are you giving me? What are you doing to me?"

Xiao Rui looked at his second brother dissatisfied.

"Brother, smell it.

Xiao Rui said angrily:"What do you smell?""

"Charcoal poison is gone."Xiao Kai said.

Xiao Rui didn't react at first, but when Xiao Kai made such a point, he immediately sniffed and his expression brightened.

"Huh? It really doesn’t smell anymore. Xiao

Kai said with emotion:"That's more than that, brother, look at our doors and windows are closed, but it's still so warm in the house, and there's no charcoal poison, tsk tsk, this is a good thing!"

Xiao Rui nodded:"It is indeed a good thing!"

Cheng Chumo bared his teeth and said to Xiao Rui with a smile:"A total of one hundred coins.""

"What?!"Xiao Rui chuckled. Is this an insult to my IQ?"Why don't you go and grab it?

Cheng Chumo held up the mallet angrily,"Yes!" I'm just grabbing it!"

The expressions of the two brothers of the Xiao family changed, and they quickly took two steps back in fear.

Du He tried to smooth things over and said,"Brothers of the Xiao family, what did you say just now? As long as we can keep the house warm and eliminate carbon poisoning, you will buy it no matter how expensive it is. Why are you regretting it now? Didn’t the Duke of Song lose his face? Or is it that you, Mr. Song Guogong, are the kind of people who don’t mean what they say?"

The two brothers of the Xiao family blushed.

Buy it, one hundred guan! It hurts!

Don't buy it, it's just like Du He said, the Xiao family will lose their face. Fortunately, Du He gave him a step.

He smiled and said:"We also know that letting you spend so much money must make you feel aggrieved, and it will also affect the relationship between us brothers.

Xiao Rui nodded hurriedly:"Brother Du is right." Du

He thought for a moment and said:"Either this, we will no longer sell this kind of thing in the future. If we regret it, we will return the hundred hands."

Xiao Kai stared and said,"Then what?" Aren’t you still collecting money?"

Xiao Rui angrily slapped his second brother on the head:"Idiot! Go get the money and give it to Brother Du!"

"elder brother……"

"Go quickly!"

After the money was given, Du He and Cheng Chumo left happily.

Looking at the two people's retreating figures, Xiao Rui smiled:"These two fools. hey-hey."

Xiao Kai muttered with a resentful look on his face:"I don't know who is the fool who gave money to others in the end.……"

Xiao Rui slapped his second brother on the head:"Hey! Why did my father give birth to a fool like you? Why are we from the same mother with such a big gap in wisdom?"

"They have just said that they will no longer sell this thing, which means they will cut off their source of income."

"But we can sell it!"

"A family of 100 guan, how much will it cost to sell a 100-guan family?"

Xiao Kai, whose eyes were a little dim at first, gradually brightened up, his energy suddenly became brighter, and he shouted loudly:"Isn't it ten thousand strings?"

Xiao Rui smiled and said nothing, looking at the sky at a high forty-five degrees.

Xiao Kai murmured, then took a breath, full of admiration, and solemnly said:"Brother! You are really good at wisdom!"

"In your words? What nonsense? Go to the pit...go sell money, go!"

The two brothers thought for a moment, and then went out. The first stop was to find Changsun Chong.

His family is a relative of the emperor, so he definitely doesn't care about this little money.

Changsun Mansion.

Changsun Chong is still in confinement.

So the two were Changsun Wuji was caught

"Uncle eldest grandson, yes, my nephew can invent a thing that can remove charcoal poison without opening the window. It only requires a hundred strings.

Changsun Wuji stared:"Seriously?" Without opening the windows, you can still keep the room warm and there is no carbon poisoning? How can this be?"

Xiao Rui said firmly:"Our family is already like this. If the eldest grandson doesn't believe it, you can try it.

Changsun Wuji said:"Okay!" Let's go, I'll try it. If it's really so powerful, a hundred pierces will be a hundred pierces."

Now the weather in Chang'an has dropped sharply, and every household is freezing in their own homes.

Although you can bake a charcoal stove, you have to open the window, and the thermal insulation effect is very average.

If you can close the window, you can still keep warm... Hiss!

Changsun Wuji sucked in the cold air.

If His Majesty is informed of such a policy to benefit the people, it is unlikely that the emperor's pet who landed in the Changsun family some time ago will be recovered.

Within a moment,

Changsun Wuji followed the two brothers of the Xiao family to the wing.

The room was warm.

A little. There was no peculiar smell. Not to mention any charcoal poison.

Changsun Wuji's eyes became brighter and brighter. He looked left and right at the charcoal stove and the iron pipes leading to the top. After looking at it for a long time, he took a long breath and said with emotion:"Okay Something! Just such a small invention is so powerful. It's just a piece of iron sheet, but we never thought that these two good boys had contributed to the Tang Dynasty."

Xiao Rui was anxious.

Seeing that Changsun Wuji kept pushing but refused to pay, he quickly reminded:"Uncle Changsun, the money... is one hundred guan.

Changsun Wuji frowned and said,"Why do you need to give me money?" Isn’t this just a piece of iron? I don’t know how to do it myself?"

After that, they walked away.

The two brothers of the Xiao family looked at each other in surprise.

They seemed to see shock in each other's eyes.

Damn it!

That's right!

Others can do this at a glance, so how can they make money? Money?

Xiao Kai said with a sad face:"Brother...were we cheated?"

Xiao Rui:"…"_Feilu reminds you: three things about reading - collection,
