Datang: My identity as prince was exposed by Li Er

Du He suppressed his nausea, shook his head and chased after Li Yi

"What's wrong?"Li Yi looked weird.

"Take a shower...your two students are taking a shower together"

"Um."

Li Yi nodded, and then pulled Du He towards the greenhouse.

Du He smiled a little ugly, and slightly distanced himself from Li Yi.

Soon, the two came to the backyard vegetable garden.

The white plain cloth was stretched lengthwise They were spread neatly on the bamboo shelf, so symmetrical that it made people feel comfortable.

Du He squinted at it for a while, pointed at the white shed and said,"Brother Li, is this the greenhouse dish you mentioned? Can you really grow green vegetables in winter?

Li Yidao:"Wouldn't you know if you go in and take a look?" Du

He nodded, looked at the white cloth tent, and said a little awkwardly:"It's pale and white, like a funeral, not festive. I'll get you some red cloth tomorrow and change it to red." It looks pleasing to the eye."

Li Yi:"……"

Naturally, he couldn't explain the principle of photosynthesis to this guy.

Li Yidian opened the door of the greenhouse first, lifted up the cloth and walked in.

Du He followed closely behind.

After entering, I felt very warm and comfortable.

It's like being in another warm world.

Du He's expression became more and more curious.

As soon as I opened the curtain, I saw rows of green summer vegetables.

He was completely shocked.

He rubbed his eyes vigorously and stared at this scene in stunned silence.

It was as if the seasons had changed between heaven and earth.

He walked out of the greenhouse again uncertainly.

That’s right!

It's snowing outside.

Can you grow green vegetables on a snowy day?

Do you want to be so outrageous?

Du He stepped into the greenhouse again, and then stepped out.

After repeating this several times, I was sure that what I saw was not an illusion.

He shouted in astonishment:"Green vegetables! Mother! They are really green vegetables! Can you grow green vegetables in winter?!"

"Damn it! Brother Li, we still didn’t believe you when you said it last time! This, this, this……"

Du He was a little incoherent.

Pulling Li Yi, he patted his face again. it is true!

"Be good! Worlds, full of wonders! Du

He let out a long exclamation and asked Li Yi,"What kind of regulations is this?""

Without waiting for Li Yi to answer, his expression became more and more curious, and he hurriedly walked to the middle of the shed after saying something. A pair of dazzling little eyes looked back and forth in the shed. He was like a newborn baby, very curious about everything in this world.

No small detail is spared

"What is that?" Du He pointed to the small iron barrels standing around the shed and said

"The stove is for constant temperature, with a fire burning inside. It uses plant ash, sawdust, dead branches, charcoal, etc. The stove is completely enclosed. The greenhouse is actually a greenhouse. Green vegetables can sprout and grow because of these stoves."

Li Yi thought for a while and gave Du He some popular science, but even thinking about it, he didn't understand.

"What does a long pipe sticking out of the stove mean?"

I have to say that Du He is a shrewd man, and his eyes are very vicious. He can see the key points at a glance.

"That is the chimney. When charcoal and dead branches are burned, they will emit smoke. The smoke cannot be discharged inside the shed because it will kill the green vegetables, so use the chimney to discharge it outside.……"

"chimney?"Du He thought about it for a while, his eyes gradually brightened.

"Well, chimneys can actually be used in every household.

In a wealthy family like your Du family, every winter, the stove is lit in the house.

But when burning charcoal, the carbon monoxide emitted...cough, smoke poison, well, the smoke poison emitted can easily kill people.

It is said that many people die every winter in Chang'an because of burning charcoal. With this chimney, people in the Tang Dynasty will no longer have any casualties when keeping warm in winter."

Du He listened attentively, his eyes rolling around.

He had already made plans in his heart, and secretly kept Li Yi's words in mind.

"good! What a good thing! Du He's eyes lit up and he said,"Brother Li, are you interested in starting a business?""

Li Yi said with a smile:"The chimney is simple to make. It is just an iron pipe. A discerning person can tell the key at a glance. Almost everyone can make it. I'm afraid you won't make a lot of money in business.……"

Du He nodded, thought for a while and said:"Whether it's to make a quick buck or a one-shot deal, you can sell as much as you want. Brother, I don't want to make too much money. You have to trust me, brother. I will come and sell as much as you want." All the money belongs to you."

Li Yi smiled and shook his head:"How can you suffer any loss? Just look at the points and count them as much as you can make."

Du He clapped his hands and said:"Okay!"

"Brother Li, please let this green vegetable grow for a few more days. I'll go pit it first... well, sell it for a sum of money from the chimney.

Li Yi nodded and said," Sure.""

……

Wait until Du He leaves.

Li Yi went to see Shangguan Yi and Di Renjie.

Li Yi was pleased.

From this Di Renjie incident, he not only determined Di Renjie's character, but also Shangguan Yi's character.

Shangguan Yi is usually a mean-spirited person.

But he is really loyal to his family members.

Di Renjie also had a stubborn temper, and Li Yi also took this opportunity to see if he would betray his master and seek refuge under another big tree to enjoy the shade.

All turned out great.

Got two good apprentices.

Lao Du is right, I will rely on you two as my right-hand man from now on.

He said to the maid:"Put the two of them on the couch to rest. There is a small stove next to them to roast them. When they wake up, feed them some gruel." After everything was explained, Li Yi went to the greenhouse to prepare his food. The green vegetables are gone.

Or have hot pot tonight? good idea

"Someone come! Go kill a cow! Just say the cow committed suicide"

……

Xiao Rui and Xiao Kai were warming themselves by the fire in their house.

It's freezing cold, so there are many stoves in the house

"Brother, it's cold. Why don't you close the window?"Xiao Rui said weakly.

Xiao Kai suddenly felt that his IQ was being pressed hard to the ground and rubbed by his brother.

He glared at Xiao Kai.He slowly weighed the fruit wine while sipping it, and said angrily:

"How stupid! How stupid! What time is it now? It’s winter! If you tell me to open the window, do you just open the window? Do you know that when the window is closed, the room is filled with charcoal poison?

Hey, our Xiao family is not prosperous. Are you going to let everyone in our Xiao family die?"

Xiao Kai suddenly lowered his head in shame, wishing he could crawl into a crack in the ground.

While the two were talking, the disciple came in a hurry.

"Dalangjun, Erlangjun, someone is shouting outside, saying that they have invented a thing that can close the window to remove carbon poison; they say it can close the window to keep warm and safe. When Xiao

Kai heard this, his eyes lit up and he said,"Brother, it's too cold. I want to close the window to remove the charcoal poison. Let's go and have a look!""

Xiao Rui wanted to beat his chest.

Is this really my biological brother? Why is he so mentally retarded!

He said angrily:"You fool, he is seeking wealth and murder! This is false selling! This is disrupting the order of Chang'an!"

Xiao Rui sneered, with awe-inspiring righteousness and righteous words:"Such a profiteer is running rampant in Chang'an and yelling randomly, and it is inevitable that some ignorant people will be deceived. As the descendants of the Duke of the country, we are appointed as the Jinwu Guards School Lieutenant, and we must maintain the discipline. This is your responsibility. My duty! Go, go teach them a fine!"

Xiao Rui's dim eyes suddenly brightened up, so the two brothers did not stay in the house to keep warm and ran out quickly.
