Play is fun, play is fun.

Li Chengqian will never be left behind.

Since he promised Li Shimin to build him a farm in Mobei, he will naturally do what he says.

But before that, he had more important things to do.

That was to build a greenhouse where crops could be grown.

The technology of greenhouse actually existed in the royal family during the Qin Dynasty.

It's just that the greenhouses at that time were relatively backward, and they could only cultivate some out-of-season flowers for people to enjoy.

For example, the flower bones in the greenhouse, which can't withstand the wind and rain outside, come from above.

However, what Li Chengqian wants is not a simple greenhouse, he wants a real greenhouse.

Therefore, not long after talking with Li Shimin, Li Chengqian began to prepare.

He first asked the craftsmen to clear a large open space in front of the paper mill, and then built a greenhouse on the open space.

Although in this era, this thing has not yet appeared.

But in the era when Li Chengqian lived, it was already everywhere.

Even when he was a child, he built it with his parents.

The clay wall has not changed in any era.

Only the load-bearing keel was changed by Li Chengqian from a steel frame to a green bamboo frame.

Under the command of Li Chengqian, in just three or five days, the framework of a greenhouse with a length of more than 100 steps and a width of more than 20 steps was built.

Now, for Li Chengqian, the only problem is to solve the lighting of the greenhouse.

Originally, he planned to replace plastic with silk cloth dipped in resin to create something that is not breathable and does not easily dissipate heat when exposed to outside sunlight.

But later, he found out that this idea was simply fanciful.

Don't talk about it, just say that silk cloth is too expensive in this era.

A piece of silk cloth costs two hundred dollars.

If you want to cover the entire greenhouse with silk cloth, you need at least nearly 100 horses.

In this way, the money spent on silk cloth alone will cost 20,000 yuan.

If you add additional materials such as resin, you will go straight to 30,000 yuan.

And Li Chengqian, a stingy guy, is reluctant to spend so much money.

So, after two full days of struggle, he still chose to buy plastic sheeting at the grocery store in the system mall.

This piece of plastic cloth cost Li Chengqian 3,000 points.

Of course, this is just the beginning.

Next, Li Chengqian bought a series of crop seedlings suitable for planting in cold and arid areas and could not be obtained in this era, such as potatoes, sweet potatoes, peanuts, and corn, in the system store.

This time, he directly spent all the points he had saved up with great difficulty.

The flesh hurt so much that he didn't sleep that night.

It was only later that he was a little relieved to see that many seeds had successfully germinated and that the effect of the greenhouse was the same as that of later generations.

With so many points, it can be regarded as a waste of money......

Cheng Huailiang looked at the potato seedlings and corn seedlings on the ground, and couldn't help asking, "Your Highness, what is this thing?" ”

"It's called a potato, it's called a potato, and the other one is called corn."

Li Chengqian bent down and touched the leaves of the potato seedlings, and said with a smile: "If these things can be cultivated successfully, we Datang people will be able to solve the problem of food and clothing in the future." ”

"Huh?"

Cheng Huailiang said in disbelief: "With this small lump of vegetable leaves, how can it be possible to solve the problem of food and clothing......"

"Don't talk about it, just say that I Xiaocheng can eat one hundred and eighty trees in one meal."

Seeing this, Li Chengqian shook his head slightly and said: "This thing doesn't eat leaves, and when it grows out, you will naturally know." ”

Potatoes, like sweet potatoes, can be eaten as a vegetable or as a staple food.

Moreover, both ingredients have a long shelf life, and they can be stored even in the cold temperatures of the north for a winter.

And this thing is extremely prolific, if it can really be promoted nationwide.

Maybe it can really achieve the effect that Li Chengqian said.

If it weren't for that, the system store wouldn't have priced this thing for a thousand points per seedling.

Li Chengqian also made a lot of determination, so he bought two potato seedlings and two sweet potato seedlings.

It also starts from this day.

Li Chengqian took his eldest grandson Chong and Cheng Huailiang to soak in the greenhouse all day long.

Half a month later, Li Shimin took his eldest grandson Wuji and Cheng Yanjin to the Qin Palace.

I was almost frightened by the appearance of these three little ones and fell to the ground.

The three cubs in front of him, except for Li Chengqian, have not changed much, and the eldest grandson is like a black monkey.

And Cheng Huailiang is not to mention, if he wears a black dress and walks in the night, he will not know if he bares his teeth, and others will not know, there is a person standing in front of him.

The eldest grandson Wuji asked inexplicably: "I said, what are you guys doing here?" How did you get this virtue? ”

Hearing this, the eldest grandson Chong and Cheng Huai appeared and smiled bitterly.

They don't want to get tanned, either.

But what can they do?

Li Chengqian came to work in the greenhouse, can they not follow?

And the temperature and sunlight in the greenhouse are much stronger than outside.

If an ordinary person stays in it for a day, the color of his skin will be one degree darker.

Only Li Chengqian, who has the same kind of guy, will not be tanned in the greenhouse.

Cheng Yanjin said nonchalantly on the side: "Manly man, what's wrong with being darker?" ”

"So what's the use of being white, do you want to be a little white face?"

As soon as this statement came out.

Li Shimin and Li Chengqian's faces darkened at the same time.

They all felt offended.

Seeing this, Cheng Yanjin also reacted that he had said the wrong thing.

hurriedly smiled and said, "Your Majesty, I didn't say anything about you, let alone Your Highness......"

"Really?"

Li Shimin snorted coldly, raised his head and said: "I will go to get ten boards by myself in a while, and if I see you not limping when I go to court tomorrow, I will get ten boards again." ”

Hearing this, Cheng Yanjin suddenly wanted to hit the wall.

Why does your mouth owe it so much?

But what can he say?

Regarding Li Shimin's order, he could only bend down and say: "The minister obeys the order......

punished Cheng Biting Jin and took revenge.

Li Shimin turned his head to look at Li Chengqian: "Didn't you say that there was a surprise to show me?" What about things? ”

"Don't worry......"

Li Chengqian grabbed Li Shimin's arm and said, "Let's go, let's go out of the city to see." ”

What he wants to take Li Shimin to see is naturally a greenhouse.

But Li Shimin didn't know those things.

He only knew that Li Chengqian had been tinkering with something recently.

At this time, seeing Li Chengqian's mysterious appearance, he couldn't help but be aroused.

So, he took his eldest grandson Wuji and Cheng Yanjin, followed Li Chengqian out of the Qin Palace, and went straight to the greenhouse.

……

{Received Surprise +99......}

{Received Surprise +63......} from Eldest Sun Mowgli

{Received Surprise +67......}

After the three of them entered the greenhouse, their expressions were surprisingly unanimous.

All three of them opened their mouths wide and looked at the green scene in front of them in surprise.

Where has Li Shimin seen a greenhouse?

Where have you ever seen that transparent plastic sheet like a water curtain?

At this moment, he was shocked by the scene in front of him, and he couldn't say a word.

After a long time, Li Shimin came back to his senses, looked at Li Chengqian and asked, "Is this ...... You made it all up with this? ”
