Let’s go back to playing and go back to having fun.
Li Chengqian will never fall behind when it comes to business.
Since he promised Li Shimin to build him a farm in Mobei, he would naturally keep his word.
But before that, he had more important things to do.
That is to build a greenhouse that can grow crops.
Greenhouse technology actually existed in the royal family during the Qin Dynasty.
It’s just that the greenhouses at that time were relatively backward and could only cultivate some off-season flowers for people to watch.
For example, the flower bones in the greenhouse cannot withstand the wind and rain outside because they come from here.
But what Li Chengqian wanted was not just a simple greenhouse, he wanted a real greenhouse.
Therefore, soon after talking with Li Shimin, Li Chengqian began to prepare.
He first asked 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, they were already everywhere.
Even when he was a child, he built it with his parents.
Mud walls have never changed no matter what era.
Only the load-bearing keel was changed from a steel frame to a green bamboo frame by Li Chengqian.
Under the command of Li Chengqian, the frame of a greenhouse with a length of more than a hundred steps and a width of more than 20 steps was built in just three to five days.
Now, for Li Chengqian, the only problem is to solve the lighting problem in the greenhouse.
Originally, he planned to use silk cloth soaked with resin to form something that is airtight and difficult to dissipate heat after being exposed to external sunlight to replace plastic.
But later, he discovered that this idea was simply unreasonable.
Apart from other things, I just want to say that silk 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 will need at least nearly a hundred pieces.
Calculated this way, just spending money on The money on the silk cloth is 20,000 yuan.
If you add additional materials such as resin, it will cost you 30,000 yuan.
And Li Chengqian, a stingy and stingy guy, was not willing to spend so much money.
So, after struggling for two days, he still chose to buy plastic sheeting at the grocery store in the system mall.
This piece of plastic sheet cost Li Chengqian three thousand points.
Of course, this is just the beginning.
Next, Li Chengqian purchased potatoes, sweet potatoes, peanuts, corn and other crop seedlings in the system store that are suitable for planting in cold and arid areas and are not available in this era.
This time, he spent all the points he had finally saved up.
His flesh ached so much that he couldn't sleep that night.
Only later did he feel a little relieved when he saw that many seeds had successfully germinated and that the effect of the greenhouse was the same as before.
So many points are not wasted...
Cheng Huailiang looked at the potato seedlings and corn seedlings on the ground and couldn't help but ask: "Your Highness, what is this thing?"
"This one is called potato or 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 people in the Tang Dynasty will be able to have enough food and clothing in the future."
"ah?"
Cheng Huailiang said with some disbelief: "How can such a small ball of vegetable leaves provide enough food and clothing..."
"I won't say anything else, but I, Xiao Cheng, can eat a hundred and eighty trees in one meal."
Seeing this, Li Chengqian shook his head slightly and said, "This thing doesn't eat leaves. When it grows out, you will naturally know."
Potatoes, like sweet potatoes, can be eaten as a vegetable or as a staple food.
Moreover, the shelf life of these two ingredients is very long, even in the north.
It can be stored in cold temperatures for a whole winter without deterioration.
And the output of this thing is huge, if it can be promoted nationwide.
Maybe it can really achieve the effect Li Chengqian said.
If this were not the case, the system store would not price this thing at one thousand points per seedling.
Li Chengqian also made great determination and bought two potato seedlings and two sweet potato seedlings.
It also starts from this day.
Li Chengqian took Changsun Chong and Cheng Huailiang to soak in the greenhouse all day.
Half a month later, Li Shimin took Changsun Wuji and Cheng Yaojin to the Prince of Qin's Mansion for inspection.
I was almost frightened by the appearance of these three little ones and fell to the ground.
Among the three cubs in front of me, except for Li Chengqian, there was no change, and Changsun looked like a black monkey.
Let alone Cheng Huailiang, if he were wearing black clothes and walking in the dark, without baring his teeth, no one would know that there was someone standing in front of him.
Changsun Wuji asked with a puzzled look on his face: "I asked you, what are you doing? How did you become such a virtuous person?"
Hearing this, Chang Sun Chong and Cheng Huai looked at each other and smiled bitterly.
They don't want to get tanned either.
But what can they do?
Li Chengqian came to the greenhouse to do some work, could they not follow him?
The temperature and sunlight in the greenhouse are much stronger than those outside.
If an ordinary person stays there for a day, his skin color will turn one degree darker.
Only a guy like Li Chengqian, who drives and hangs the same clothes, will not get tanned in a greenhouse.
Cheng Yaojin said nonchalantly from the side: "A man, what's wrong with being darker?"
"Then what's the use of being white? How about being a pretty boy?"
As soon as this statement came out.
The faces of Li Shimin and Li Chengqian darkened at the same time.
They all felt they were offended.
Seeing this, Cheng Yaojin realized that he had said the wrong thing. He quickly smiled and said: "Your Majesty, I, Old Cheng, didn't talk about you, let alone His Highness..."
"Is it?"
Li Shimin snorted coldly, raised his head and said, "I'll go and get the ten pieces later. If I see you're not limping when you go to court tomorrow, I'll get another ten pieces."
Hearing this, Cheng Yaojin immediately wanted to hit a wall.
Why is my mouth so weak?
But what can he say?
Regarding Li Shimin's order, he could only bend down and say: "I obey..."
After punishing Cheng Yaojin and taking revenge.
Li Shimin turned to look at Li Chengqian: "Didn't you say you had a surprise for me? Where are the things?"
"Don't worry..."
Li Chengqian took Li Shimin's arm and said, "Let's go out of the city to see it."
What he wanted to show Li Shimin was naturally the 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 look, he couldn't help but be aroused in curiosity.
So, he took Changsun Wuji and Cheng Yaojin, followed Li Chengqian out of the Prince of Qin's Mansion, and went straight to the greenhouse.
…
{Received surprise value +99 from Li Shimin...}
{Received surprise value +63 from Changsun Wuji...}
{Received surprise value +67 from Cheng Yaojin...}
After the three people entered the greenhouse, their expressions were surprisingly consistent.
The three of them looked at the green scene in front of them with their mouths wide open.
Where has Li Shimin seen a greenhouse?
Where have you seen that plastic sheet that is as transparent as a water curtain?
At this moment, he was so shocked by the scene in front of him that he couldn't say a word.
After a long time, Li Shimin came back to his senses, looked at Li Chengqian and asked: "This... is this all caused by you?"
