The underworld signed in for a thousand years, reincarnated as an angry and crying empress

“Minnu, see His Royal Highness the Crown Prince Chitose.”

Seeing Li Chen, Liu Sichun and the others immediately put down what they were doing and came to see him.

Looking at a young man behind Liu Sichun with a respectful and excited expression, lowering his head and not daring to look at himself, Li Chen said, “Let’s all be disrespectful.”

“Your Highness, this is Liu Sida, the second brother of the people’s daughter, this time he went to Zhejiang Fujian to buy sweet potato seedlings, all of which is the credit of his hard work all the way.”

Under Liu Sichun’s introduction, Liu Sida came to Li Chen, respectfully saluted again, and said excitedly: “Caomin Liu Sida, I have seen His Royal Highness the Crown Prince, His Royal Highness the Crown Prince Chitose, Chitose, Chitose. ”

Excuse me.”

Li Chen glanced at Liu Sichun thoughtfully and said, “How many seedlings were purchased this time?”

Liu Sida hurriedly replied: “There are more than 400 seedlings in total, in addition to the losses along the way, there are still more than 380 plants alive now, and the grass people have also invited farmers with planting experience from the local area to sow the seeds themselves.”

Li Chen nodded in satisfaction and said, “Not bad.”

Although it was only two words, it had already made Liu Sida excited.

“It’s just that Your Highness, this cold and freezing day, can it really be planted?” Liu Sichun asked.

Li Chen smiled and said, “Naturally, you can, otherwise this palace asked you to prepare for such a thing.”

Saying that, Li Chen took Su Jinpa to the edge of the field.

Although it has been cleaned, this snow is muddy and the edge of the field, and the ground is naturally not clean.

Within two strokes, Li Chen’s boots and trouser legs were already stained with mud, and Su Jinpa beside him was no better.

It’s just that neither of them cares about these details.

Su Jinpa looked at the almost constructed greenhouse on the field quite curiously, and asked, “Your Highness, what does this mean?”

“This thing, the main palace named the greenhouse.”

Li Chen pointed to the newly erected frame on the field and said: “Use delicate soft but tough bamboo strips as skeletons, tie and connect each other, and then cover them with glass and copper mirrors that are hand-polished to transparency.

“In this way, it does not block the sunlight, but also isolates the internal and external temperatures, providing a good and suitable ambient temperature for the plants inside.”

“Therefore, as long as it is properly cared for, it is no longer impossible to eat watermelon in winter.”

The more Su Jinpa next to him listened, the more magical he felt.

Not only her, but even Li Keshou and Liu Sichun, who were in charge of construction, no one knew the true purpose of this thing.

Now Li Chen explained, everyone felt incredible.

Everyone knows that watermelon is a summer crop, it needs hot weather to grow, and it is impossible to eat watermelon in winter.

But this thing made by His Royal Highness the Crown Prince can actually grow vegetables and fruits against the season, and such a magical thing?

Originally, the best material for making greenhouses was plastic film, but in this era, plastic is impossible to produce, Li Chen is not a chemical talent, so think about it, can only use copper mirrors by manual polishing, although time-consuming and laborious and costly, but fortunately he is only temporarily reclaiming a test field, but it does not cost much.

Li Chen came to the greenhouse, and everyone followed, only feeling that the inside was a little stuffy, but he could clearly feel that the inside was much warmer than the outside.

Taking out a handful of seedlings, Li Chen turned his head and said to Su Jinpa: “This thing is called sweet potato, and because it is a thing from Fanbang, it is also called sweet potato, dozens of stones per acre, twenty times better than the planting valley.” Moist and edible, or boiled or ground into powder, raw food such as kudzu, cooked food like honey, taste like water chestnuts.

“It is originally an annual birth, but if it is properly fertilized and cared for, the harvest period can be shortened to half a year, plus it is extremely adaptable, and it can be planted in most places in the land of China, Jinpa, you say that if this thing is promoted on a large scale, but is it a blessing for Daqin?”
