The crisp sound instantly reached everyone's ears, but what was more striking than the sound was the bright light source overhead.

"Ah!!h

"Success!!!"

"What's wrong? What's wrong? What is it? ”

The bedroom was instantly bright, which made Jiang Yan and the others scream excitedly, while Lu Lili, who was holding Kaka on the side, looked at the light bulb above her head with a frightened face.

The sudden appearance of the little sun made Lu Lili unable to understand at all, seeing the excited two people beside her, Lu Lili put down the Kaka in her arms, wanted to touch the light above her head, but stretched out her hand but touched the air.

"Sister, what is this?" The fingers fell into the air, Lu Lili turned her head and looked at the excited two people beside her, Lu Lili held down the latter's constantly jumping body, trying to calm the latter down.

"It's a lamp! Lamp! Lamp! We can stay up late in the future! ”

Hearing Lu Lili's doubts, Jiang Yan on the side turned his head, with an excited smile on his face, and explained with a smile.

Hearing Jiang Yan's words, Lu Lili vaguely understood, holding Kaka, Lu Lili sat on the kang and looked at the light bulb overhead, which was completely different from the darkness of the outside world, and the bedroom at the moment seemed to have a sun.

Hugged each other excitedly, Jiang Yan came to other rooms, and as the light bulbs lit one by one, Jiang Yan's excited voices came and went.

The light bulb in the courtyard lit up with the change of the switch, although it could not illuminate the entire courtyard, but it also illuminated the part of the door, Zhao Dabai, who was lying on the side, suddenly found that the door was lit up, and ran behind Jiang Yan in horror, raised his head and looked at the bulb above his head timidly.

"Hahahaha!"

Zhao Dabai's timid appearance made Jiang Yan laugh constantly, rubbing Zhao Dabai's head, Jiang Yan walked to the courtyard and admired everything about himself.

From the very unclothed at the beginning, to the current bright lights, Jiang Yan took half a year, and now, Jiang Yan finally saw some civilization.

This kind of life belongs to her, a person from a civilized world.

"I thought the books were all lies, but I didn't expect them to be true." Watching everything, Lu Linlin behind him smiled and spoke.

After working all day, Jiang Yan and the others didn't even eat, looking at the lights lit up in the courtyard, all kinds of moths gradually gathered over, which made Jiang Yan feel a little familiar, and the scene in front of him was exactly the same as when he was a child.

Vegetable garden, pond, night, moths.

The excited expression instantly became stiff, and scanning everything around him, Jiang Yan suddenly felt a little sour.

"When I was younger, I used to put tractors here." Looking at a position in the courtyard in a daze, Jiang Yan opened his mouth abruptly.

Lu Lili, who had not yet reacted on the side, noticed that Jiang Yan's mood was wrong, and sat on the side, supporting her chin with her hands.

"At that time, there were not many families in the village with tractors, so my father was able to make a little money from tractors at that time." Sitting on the bluestone, Jiang Yan stroked Zhao Dabai beside him and spoke quietly.

Lu Linlin on the side was no longer fanatical, sitting next to her sister, admiring the vegetable garden in front of her.

"When summer approached, my mother would often pick a cucumber and wash it at the well and eat it directly."

"At that time, we got out of school very early, and we came home at 3 p.m., and then we kids played together and the whole village ran."

"Sometimes they come to my house because I have waste tires, and when I was a kid, my mom would cut the tires into strips and play with them."

As if going back to the past, Jiang Yan quietly recounted what happened when he was a child, while Lu Linlin and Lu Lili on the side sat and listened as if they participated in Jiang Yan's childhood.

。。。。。

Jiang Yan and the three of them didn't know how long they chatted last night, and when they woke up this morning, the time displayed on the sundial had reached ten o'clock.

There is not much food left in the house, and the dark clouds have been entrenched since last night, and by this morning, the dark clouds have firmly covered the sun, which makes Jiang Yan, who is short of food, even more anxious.

With all kinds of fishing tools, Jiang Yan pulled up the three people who were still a little drowsy, and hurried to the Xinglong River, although the last time he ate fish for nearly a week, but this time there was really no way, if he wanted to go to Bailong Mountain to hunt, the efficiency was slower than fishing after all, and now Jiang Yan has not much time.

After four hours of busy work, Jiang Yan watched the dark clouds getting darker and darker, and hurriedly took the Lu family sisters back to the farm.

Half a minute later, the rain began to whistle.

"Hey! Hey, take a shower! ”

In the courtyard, a cucumber is perched on its back and enjoys the rain.

With the Lu sisters to cover the whole room with the lead cloth, Jiang Yan took out three sets of protective clothing from the storage room, and under the doubts of the Lu sisters, Jiang Yan assisted the two to put on the protective clothing, and then sat in front of the window, lifted the lead curtain and observed the situation outside.

Jiang Yan has seen a lot of news about the understanding of nuclear radiation, and the decay period of many nuclear wastes ranges from thousands of years to millions of years, and before that, human beings launched a large number of nuclear weapons in order to compete for oxygen, which made the entire earth basically in serious nuclear radiation.

Although Jiang Yan has done a lot of defensive measures, Jiang Yan also knows very well in his bones that nuclear radiation will not disappear because of a rain, but even so, Jiang Yan must do his best to resist radiation when it rains, not for anything else, just for peace of mind.

Rain in the north is not common, at most it will rain for three or two days in a row, and Jiang Yan will choose to go out three days after the rain every time, so that Jiang Yan can accept the outside world irrigated by radiation.

Maybe it's the reason why she was once burned to death by radiation.

The heavy rain lasted for a day and a night, lying on the kang, Jiang Yan looked at the ceiling boredly, at the beginning Jiang Yan also talked with the Lu sisters about nuclear radiation, and when he got to the back, Jiang Yan had already talked about everything he could talk about, and he didn't even have anything to say.

After four days, Jiang Yan finally removed the lead cloth and stepped out of the room.

The fierce sunlight made Jiang Yan in the dark very uncomfortable, looking at everything in the courtyard as usual, Jiang Yan hurriedly opened the door of the chicken coop, hungry for so long, these chickens are afraid that they are not going to jump to someone else's house.

After looking at everything around and finding that there was nothing unusual, Jiang Yan came to the neighboring garden with the pipe.

The paddy fields in the greenhouse need to store water, and Jiang Yan has not been left alone before, and after four days, the water level in the paddy fields has dropped a lot.

The water level of the well water rose by nearly ten meters due to the rain, and the ginger smoke released the water into the paddy fields by pulling the pipe.

After nearly an hour of busy work, all the care of the farm was handled by Jiang Yan, sitting on the chair and taking a sip of water, Jiang Yan thought about what to do next.

Without a mobile phone and nothing to do, Jiang Yan, who was suddenly idle, was a little uncomfortable, scanning everything around him, Jiang Yan wanted to find something to keep himself busy.

"Sister Yan, how are you going to use this generator?"

In the farmhouse, Lu Linlin walked out with the magnetic induction generator that Jiang Yan found in the school before.

Hearing this, Jiang Yan instantly turned his head, looked at the generator in Lu Linlin's arms, and instantly remembered his previous plan.

She wants to make a hydroelectric generator!
