"Brother Yan is so powerful, I want to be like him when I grow up. Then sister, why did solar energy become the moon? ”

“…… See? There are panels here, monocrystalline silicon solar cells, this thing is the core, it can convert solar radiation energy into electrical energy and store it, in addition to these, there must be a special controller, this is the switch, we need to turn it on when we need it, and turn it off when we don't need it. ”

"I know, like now we need it, we have to turn it on, it can control the moon to shine, and when we go to sleep later, we turn it off and the moon goes out."

“…… That's right, Xiao Ran's comprehension ability has improved again. Tonight's braised pork was not eaten in vain. ”

The little one was praised and was both excited and blushing.

"But how did Little Moon make it? Is this our window pane? ”

"This is not a window pane, this is an LED light, and you need to read a lot of books to make this out, and this is the lamp shell, and the inside of the lamp shell is your moon, and this lamp pole, everything needs the knowledge in your head to build technology."

One big and one small, one asked and one answered, the other people around held their breath and listened, their hearts were more shocked than Xiao Ran, unconsciously, the Jiang family's courtyard has been surrounded by three layers inside and three layers outside, and it is gradually making up for the outer circle, and there is a trend that the whole village is rushing here.

Although everyone didn't understand what Xiao Mingyue of the Jiang family said, they knew that it was very powerful, and they looked up to Yan Jinzhi more and more, and some parents with children immediately asked their children if they wanted to be a person like Comrade Yan when they grew up, without exception, they got a satisfactory answer, and they pondered in their hearts, and they had to hurry up to urge the village committee to build a school.

If this sentence used to be an abstract concept and they didn't understand it at all, now they who can't read and write can understand it.

Comrade Yan was not born to do so, he made himself a knowledgeable person step by step through study, their village must build a school, no matter how hard they work, they have to send the children to the school to study, in the future they will grow into such an amazing person as Comrade Yan, they have to go to the village committee to exchange some tickets, while they still need money in their hands, they have to hurry into the city to buy some school utensils to prepare, maybe soon the children in the family will be able to use it, their generation is too late, but the children can.

With this idea, they didn't even think about the next month's penny, the first thought was to build a school as soon as possible, which is the most important thing, and the villagers who gradually changed their concepts did not notice their own changes, anyway, they followed their hearts.

This night, the people in the village seemed to be not sleepy, and they kept asking questions around Yan Jinzhi, from the stumbling expression at the beginning, to the level of questions in the back, and Yan Jinzhi has been patiently answering, explaining to them with metaphors they can understand, if it wasn't too late, for fear of delaying Comrade Yan's rest, they could pull people to ask until dawn.

Some people also thought about it, and said that if they could get such a lamp in front of their house, it would be both convenient and convenient, so they counted the money in their hands and pondered to get one, but when they asked, not only was it expensive, but the materials were also very difficult to get together, and Comrade Yan could say that they had searched all over the country.

He also promised to install a free one in the center of the barn field, so that the grain can be seen at night when the harvest is harvested, and the children can also go to run and play at night, and the adults can also gather there to chat after dinner, which is comfortable, and the pain of farming is not so much to be taken to heart.

However, Yan Jinzhi exposed another piece of information, he can make a biogas digester, and also give a cost price, 30 yuan per mouth, he can also teach the technology to the village for free, so that the village committee organizes personnel to learn to do it door-to-door, and if they are willing, they can pay the cost price, and then match the stove and light bulbs to cook and illuminate.

This time, many people go back and think about the biogas digester, they don't think much about cooking with a stove, but they are hungry for lighting.

School, the biogas digester, this night, these two things went back and forth in their heads, like magic sounds until dawn.

And Yan Jinzhi and Jiang Mingyue here, because Jiang's mother had reserved a room before, Qiao Mingtang not only didn't have to go to Jiang Ming'an's place to live, but also had a separate room here, this time, Yan Jinzhi was not disturbed, closed the door and locked it, tacitly entered the space, and landed in the bamboo forest courtyard almost at the same time.

"Do you really want to make a lamp for free in the barn?" The reason why Jiang Mingyue asked this was not because she was reluctant, because she knew too well how precious this lamp was in this era, and of course, the cost was also very high, and she was worried that this person had no money.

But when the question came out, she didn't need him to answer, because she knew the answer.

"I have a lot of money in my coffer, and I'll give it to you."

Yan Jinzhi: "It's impossible not to be moved by the ......, but there are also some crying and laughing, Yan Jinzhi thought about it: "I am also a person with savings, and this money will not empty my wallet." ”

The implication: I have the money to marry a daughter-in-law, but you can ask for it from me.

"Wait, my wheat is ripe, I'll harvest it first."

Jiang Mingyue also remembered that the wheat had passed the ripening period.

Soon after the harvest, she began to plough the ground again, weeding and planting sweet potato vines, and this time she planted sweet potatoes wherever she could.

After planting, continue to chat with Yan Jinzhi.

Yan Jinzhi: "You try your spatial spiritual power, it should be upgraded again." ”

Although Jiang Mingyue didn't know what kind of changes the upgrade would bring, it didn't prevent her from bumping into it, such as turning the four major real estate yards in the city in seconds, and even the special place of Wuyun Mountain also turned around, she remembered that the last time she met Zhan Cailian's gang in the city, she wanted to go back to Qingshan Village in seconds when she entered the space, but not at that time, this time she wanted to try whether the upgrade was promoted here, but unfortunately, as long as she jumped out of the street outside the property and entered the space, she was still in the same place, and she couldn't come back to Qingshan Village at all.

I tried other places, and it was the same, nothing changed.

She returned to the Bamboo Forest Courtyard and looked at him very depressed: "Yan Jinzhi, this time you guessed wrong, there was no upgrade at all, it must be that I didn't donate enough, and I didn't stay for three days and four nights to save people like Cangxian." "It's not enough!

Yan Jinzhi lowered his eyes and thought for a moment, "I'll try." ”

In the next second, Yan Jin went up to Wuyun Mountain, went to the four properties of Xiaoyue in Nanxi City, and returned to Qingshan Village by himself.

Jiang Mingyue was shocked and tasted it too!

"Why do I benefit from upgrading?"

Yan Jinzhi: "......"

"Yan Jinzhi, you are a bug on my life path."

Yan Jinzhi: "......" is not enough.

In order to coax people, Yan Jinzhi decided to accompany her to make money, so she proposed: "Do you want to go to the city to sell your wine?" ”
