In the blink of an eye, winter was approaching, and Li Xi looked at the seeds that had been packed into a few small boxes by himself a few years ago.

Although she said that she wanted to get greenhouse vegetables, the most important thing about greenhouse vegetables must be greenhouses, and the materials of greenhouses are plastic.

This is ancient times, there is neither oil nor plastic, so she can't use a few bamboos as a greenhouse.

Li Xi only felt a headache, and lay on the bed with a strange scream.

Yun, who was cooking in the kitchen, heard that his daughter's voice was wrong, so he quickly wiped his hands and ran into Li Xi's house: "What's the matter, Sanya?" ”

Li Xi just wanted to vent the helplessness in his heart, but he didn't expect to be able to lure the Yun family over.

She sat up with a "whew" and put away the bitter gourd face just now: "It's okay, mother." ”

"How can my mother not understand you."

Yun wiped his hands and sat in front of Li Xi, and gently stroked the broken hair around her ear: "What problems have you encountered?" ”

Li Xi sighed, knowing her daughter Mo Ruomu, even if her current body has changed, the Yun clan still knows Li Sanya best.

But......

Li Xi looked at the rows of rapeseed on the table, thinking to himself that farming was such a thing, after all, the Yun family and Li Erbi knew better, why didn't they ask them?

Thinking of this, Li Xi suddenly felt that he had strength again, and "Gollum" got up and came to Yun's side: "Mother, have you ever thought that one day we can eat fresh vegetables in winter?" ”

"What?"

Yun's made Li Xi stunned: "Can you eat fresh vegetables in winter?" ”

Isn't her daughter dreaming?

She reached out and touched Li Xi's forehead.

Li Xi was a little speechless, and gently took Yun's hand down: "I don't have a fever, mother, I mean seriously, now my daughter has a way for our family to eat fresh vegetables in winter, maybe we can sell them in the market." ”

"Really?"

The Yun clan looked at Li Xi suspiciously, still not believing what Li Xi said.

Li Xi had no choice but to sit upright and explain to Yun's the greenhouse vegetables in his impression:

"For example, if you have something transparent, you put it on the ground, and then the sunlight comes in through this transparent thing, and it stays here, and it becomes warm, and you can use the land to grow vegetables after a period of warmth."

Although Li Xi already felt that he had spoken in great detail, Yun still felt that he was listening to the clouds.

She scratched her head, not quite understanding Li Xi's concept.

Li Xi was a little helpless, thinking that maybe men would accept this kind of thing a little faster than women.

So she simply called Li Er over and explained the concept of greenhouse vegetables to these two people.

Fortunately, Li Er understood and accepted it faster than Yun's, and quickly understood what Li Xi meant.

Li Xi saw that Yun still didn't understand, so he had to take a piece of paper, roll it into a semicircle, and buckle it on the ground: "Mother, look." ”

She used a pen as sunlight: "This greenhouse is buckled on the ground, because this special material has a thermal insulation effect, especially in winter, there is a way to let the heat of the sun go in and out, so that the temperature in the greenhouse can be guaranteed, and because this material is transparent, so when the vegetables grow, there is sunshine and temperature, we can eat vegetables as much as in summer." ”

Maybe it's because Li Xi has repeated it too many times, or maybe it's because there is a physical explanation this time, Yun finally understands what Li Xi means: "In this case, we can also eat fresh vegetables in winter, which is quite good." ”

"yes, if there's any leftovers, it can be used to make money."

Li Er smiled happily, and kept praising their three girls for being smart.

Li Xi was a little embarrassed by the praise of this simple husband and wife, scratched his head and said the most realistic question: "It's a pity that this is just a daughter's idea, according to our current conditions, where should we find this transparent cloth-like material." ”

At this point, the three of them were silent at the same time.

Hey, it seems that technology is not only a ladder to promote human progress, but also something that can make human beings money.

In ancient times, Li Xi knew how much he didn't know how to cherish in modern times.

Looking at the father and daughter who were sighing face-to-face, Yun suddenly had an idea: "The cloth we use to make clothes on weekdays will be scorched with a fire, which can achieve the airtight effect that Sanya just said, if the cloth is big enough, it's okay." ”

As soon as this remark came out, it was immediately opposed by Li Er's father and daughter, and Li Er was a little worried: "No, old woman, you have said it, the cloth will be scorched as soon as it is baked, and how can it be transmitted when it is burnt." ”

"Yes, mother, and that cloth can't be used as a material for a greenhouse once it's hard."

Hearing their objections, Yun had no choice but to sigh and go back to the kitchen to cook again.

Seeing the lost eyes of the Yun family when she left, Li Xi suddenly felt a little unbearable, she turned her head to Li Er and said, "Dad, otherwise, let's try it with my mother's method, what if it happens?" ”

"But ......"

"Let's try, let's try first."

Li Xi knew that before he came, the family lived a poor life, and now that life has finally improved, he must be poor, for fear that he will have money if he doesn't get things right.

Hearing Li Xi say this, Li Er agreed to give it a try.

The two of them said they would do it, and immediately put on a thick coat and prepared to go to the nearby market to buy it.

Yun, who was cooking, heard the sound of the door, and poked his head out to see the father and daughter walking towards the door.

Her meal hasn't been cooked yet, what are these two people going to do?

"Sanya, her father, you two are going out?"

Li Xi turned around: "Mother, my father and I think we can try the method you just said, let's go to the nearby market to buy a white cloth first, and come back in a while." ”

"Okay, okay, let's go."

Hearing that Li Xi had adopted his own method, Yun's unhappy heart was fake, and he immediately waved his hand to let the father and daughter go.

Li Xi nodded, and followed Li Er's pace towards the nearest market.

Along the way, the father and daughter had their own thoughts, and neither spoke.

Because Li Xi didn't want his father and mother to worry about him, they didn't know about Li Biyun's framing of Li Xi until now, so they naturally didn't know about Li Xi's more than 200 taels of silver.

She is now worried, if the greenhouse is successfully developed, how should she explain to her parents where the cost of this greenhouse comes from.

Just as they were thinking, the father and daughter went to the nearest market to their home.

Li Er's eyes were sharp, and he was the first to see that the third stall in the east side market was a cloth stall, and he pulled Li Xi: "Sanya, you see that there seems to be a white cloth there." ”
