Hearing Li Er's words, Li Xi's eyes lit up, and he immediately looked in the direction that Li Er was pointing at, and found that there was really a piece of white cloth swaying in the wind.

She was overjoyed, and immediately pulled Li Er and ran over, stood in front of the stall, and pointed to the white cloth that was not too big or small: "How much is this cloth boss?" ”

The boss looked very honest, and scratched his head a little embarrassed after seeing that the person who came was a little girl: "That's the latest arrival, it takes twenty yuan a horse, you little girl ......"

Before he could finish speaking, Li Xi took out twenty yuan from his sleeve: "Get me one." ”

The boss was stunned, as if he didn't expect Li Xi's little girl to be so generous, and immediately took a new cloth from the cart for Li Xi: "Can you take it yourself?" ”

"There's my dad."

Li Xi grinned, pointed to Li Er, who was as honest and honest as the boss behind him, and took the white cloth from the boss and handed it to Li Er.

rushed home, just in time for Yun to put the dishes on the table.

Seeing their father and daughter coming back with a piece of cloth, the Yun clan immediately beckoned: "Come and eat, and then make a greenhouse after eating." ”

Li Xi, who had walked all the way, was already hungry, and he drooled when he smelled the aroma of the food, agreed and immediately went to wash his hands.

"It's so fragrant, mother."

"Hungry, let's eat."

The family sat happily together and discussed the problem of greenhouse vegetables.

"Mother, later my father and I thought we should try the method you said, so the two of us went to the market and bought a white cloth, and we will use a little bit of it later."

Li Xi stuffed a mouthful of rice into his mouth and said to Yun Shi, who was sandwiching vegetables for himself and Li Er.

Yun thought that his plan had been rejected, but he didn't expect that his daughter and husband would still be willing to give it a try for her.

She was happy in her heart, but she said, "I look at the material of that cloth, and it cost a lot of money, right?" ”

"Don't worry, mother, my daughter can still afford it with a little money in her hand now."

When it came to money, Li Xi's heart couldn't help but feel empty, after all, he didn't let Li Er and his wife know about Li Biyun's coming to her that day.

At this point, the family stopped talking, and after eating the lunch quietly, they went to light a fire and try to bake the cloth hard.

Whether it is in the previous life or in this life, Li Xi is the most flexible and hands-on person in the family.

So she didn't let Yun and Li Er interfere in the matter of hardening the fabric, but tried to do it herself.

She asked Yun to cut out a piece of cloth that was both long and wide, and then put it on the fire to roast.

originally thought that it should be a very simple thing, but in Li Xi's hands, either the fabric was directly burned out of a hole or turned black directly, and there was no way to be as airtight and light as Yun said.

Looking at the pile of ruins in front of him, Li Xi crossed his waist and sighed, muttering to himself: "It seems that the cloth of this era can't be compared with those fibers at all." ”

Li Er and Yun, who were sitting next to her, didn't hear what she said clearly, and only thought that Li Xi was a little sad because the experiment was not successful.

Yun Shi walked over and patted Li Xi on the shoulder: "Sanya, it's not your problem, it's because my mother didn't think about this matter thoroughly, and forgot that this fabric will turn black after baking, don't be sad." ”

She has always had a soft and weak personality, and she will only be tough when she encounters something unfavorable to Li Xi, otherwise she will always be this soft, weak, and empathetic look.

Li Xi knew that the Yun family was afraid that she would be disappointed, she was a little moved in her heart, and turned to smile at the Yun family: "Mother, my daughter is not discouraged, she is trying to find a way." ”

Although I was not discouraged, I was a little worried in my heart.

In fact, the method that the Yun clan thought of was already good in this era, maybe they couldn't operate it?

No, it's fabric.

Li Xi sighed in his heart again.

She looked up at the sky and saw that it was almost sunset.

She turned her head: "Dad, mother, you've been busy with your daughter all afternoon, are you tired?" ”

"Daddy isn't tired."

Li Er stepped forward: "It's just that this fabric doesn't work, what should I do?" ”

That's a good question.

Li Xi had no better way, so he had to be vague: "The solutions are all thought up by people, and no way now does not mean that there will be no way in the future, my daughter already has an idea in her heart, but I don't know if it will work, you don't have to worry." ”

Hearing Li Xi say this, Li Er was relieved.

He nodded and turned his head to look at the Yun family: "Mother, are you hungry?" ”

After all, the Yun clan was also busy all afternoon.

He didn't say that it was okay, but when he said that Yun did feel empty in his stomach: "Don't say it, it's really a little." ”

She got up: "You two continue to figure out a way here, I'll go cook." ”

"Okay."

Li Xi nodded, looking at Yun's back and continuing to worry.

Seeing his daughter holding her chin with a sad face, Li Er, who has never been very flexible, suddenly had a flash of inspiration: "Sanya, does this greenhouse still need regular ventilation?" ”

Li Xi didn't know why Li Er suddenly remembered to ask this, so he could only answer truthfully: "Although you don't need to ventilate every day, you do need regular ventilation when the temperature is too high." ”

"So what else should I pay attention to?"

Looking at the sparkling light in Li Er's eyes, Li Xi was embarrassed to say that he hadn't actually come up with anything.

She swallowed a mouthful of saliva and thought for a while before saying, "There must be the light needed for the growth of vegetables, such as the kind of day and night change, and the rest, it seems that there is nothing." ”

"Oh."

Li Er nodded thoughtfully and stopped talking, lying on the table as if thinking about something.

Li Xi felt strange in his heart, and asked Li Er: "Dad, what do you do?" Why did you suddenly ask your daughter like this? ”

Li Er has always been honest and honest, he is an out-and-out stuffy gourd, and he rarely asks so many questions at one time like this.

Today, he was suddenly able to say something about the issue of vegetables in the greenhouse, which made Li Xi feel a little incredible.

Hearing his daughter ask him, Li Er smiled and scratched his head: "Dad just suddenly thought, if there must be light and impermeable, how about using a house to replace the roof with transparent paper?" ”

"What about the temperature?"

"We can make a small kang that is not very high, put the vegetable seedlings on the kang, and go to the grove at the east end of the village to collect some firewood when we have nothing to do, and burn more all day and night, what do you think?"

Hearing Li Er's method, Li Xi's eyes couldn't help but light up.

Although the light transmitted by the bright paper is not as transparent as plastic, it is enough for the vegetables growing in the greenhouse in winter, and the temperature can indeed be like what Li Er said, put those vegetable seedlings on the kang and burn more!

She turned her head excitedly, feeling that she was about to cry out with joy: "Dad." You're so smart! ”
