Sure enough, I ran upstairs and downstairs all afternoon, and I didn't see them again, and I found out anything.

Before it was time to eat, the two children came back with their heads drooping.

Xu Dong pouted: "I can't find it." ”

"We even picked up the wet firewood in the firewood room, and there was nothing." Xu Xi spread his hands.

Ning Jin felt that it was normal to not find it.

The dean usually kept things she didn't use often in the attic, and the household and farm tools were piled up in the utility room behind the kitchen, and the food and important things were locked in the pantry and double-door cabinet in her room, which were the places where she used to put (hide) things.

Now there's another dormitory for employees.

But when did the dean go out and buy so much rice and come back?

Could it really be that I went to the supermarket to buy it on the first day of Yinyin's fever?

How did he remember that day when it rained so much, many rooms were either leaking or seeping, and the dean had been worrying about the children's accommodation and didn't have time to go out?

Ning Jin's little head kept pondering.

If Xu Yin knew that he had spent the afternoon pondering the origin of the pile of materials in the hired dormitory, he would have twitched the corners of his mouth—he was really a little worried.

……

Another ten days passed in the blink of an eye.

Due to the high terrain, the water in the yard has completely receded, but the river outside is still full and overflowing, and most of the streets and roads are still flooded.

The water level has dropped a lot, and you can go out for a walk in rain boots, but you are also afraid of stepping on thunder - such as falling into a manhole cover or slipping into a drainage ditch, or worrying about bacteria in the stagnant water.

The four children have nothing to do, chopping firewood, drying firewood, drying clothes and quilts in the morning, and listening to programs around the radio in the afternoon.

The TV can't be watched, the cable TV is out of order, and it's snowflakes when it's turned on.

They brought over the radio that the dean's mother used to listen to opera, put it on a stool, and each of the four of them sat around with a small bench, holding their cheeks and listening carefully.

“…… Dear listeners and friends, the following is a notice: according to the latest news from the Meteorological Observatory, in the coming week, the temperature will gradually drop, and after a week, most areas may drop to zero or even lower, and there will be snow and freezing. At the same time, low temperature, rain, snow and freezing weather will have varying degrees of impact on power, communications, agriculture, forestry, transportation and other industries, please relevant departments in advance maintenance, do a good job in scheduling ......"

The host broadcast it three times in a row.

Xu Dong scratched his head: "What is this aunt talking about?" Frozen snow? Are we going to snow here? But we're still wearing short sleeves! ”

At most, get up in the morning and put on a coat.

Strictly speaking, it was only the end of summer, and due to a rain that lasted for half a month, the temperature dropped to about the same level as early autumn, and you need to put on a coat in the morning and evening.

But it was still quite hot after noon, and Xu Dong, who had the strongest bones, took off his coat before lunch.

Xu Xi tilted his head and said in a glutinous voice: "Is this aunt talking about the Northeast?" The dean's mother said that the winter in the Northeast is getting long, and we are still wearing short sleeves, and they are going to wear padded jackets over there. ”

Ning Jin frowned and shook his head: "I don't think so." This is a local radio station, and the host said, 'I hope the citizens and friends will tell each other'. ”

Xu Dong and Xu Xi looked dazed, indicating that they didn't understand.

Ning Jin stood up with a serious face: "It means that it is going to snow here!" ”

Xu Dong's eyes lit up: "Really? Then we can play snowballs and have snowball fights! ”

“……”

Xu Yin suddenly felt a little sympathetic to Xiao Jin's classmates, one of the little friends was brainless, one was squeamish, and one was low-intelligence, so he couldn't take it.

Fortunately, his head is not as smart as Xiao Jin's, but his ability to follow the trend is still good.

Ning Jin said that he wanted to prepare for the sudden drop in low temperatures a week later, Xu Dong and Xu Xi were as diligent as little bees, running up and down to sweep the building and carry quilts.

They gathered together the mattresses, quilts, and thick winter clothes from all the rooms and pushed them to the middle of the courtyard to dry in small carts.

After drying it, they instinctively want to go to the cellar, because the cellar is warmest in winter, and they have experienced this first-hand.

In the cold winter months of previous years, they hid in the cellar in hide-and-seek, so warm that they didn't want to come out.

The dean's mother also often carried some food that was easily frozen into the cellar.

But this time, Xu Yin stopped them and pointed to the entrance to the bunker: "Go there." ”

"It's dark there, and I'm scared." Xu Xi hid behind Xu Dong.

Xu Dong was also afraid, but he was a man and couldn't show his timidity, so he puffed up his small chest: "Yin Yin, it's too dark and not fun there, let's go to the cellar!" ”

"It's not dark." Xu Yin said.

She waited for her friends to fall asleep last night and went down to see, although the robot has not been fully completed, but the main part has been completed, the transition area on the first floor, the drying, planting, breeding, monitoring area on the second floor, the residential living area on the third and fourth floors can be put into use, the robot is currently debugging the groundwater filtration system on the fifth floor, laying sewage pipes, and installing geothermal power generation equipment supplemented by coal.

In addition, she also quietly installed a set of concealed intelligent lighting system to prevent high temperature, freezing and blasting in the irrigation jungle behind the welfare home, which is the product that she invested in Aoxing Technology in the last small world after the "Wisdom Eye".

The lighting system, as the name suggests, is to use light pipe technology to collect sunlight and transport it to the basement, bringing natural light to the basement, which is as bright as day without turning on the lights during the day, which is not only energy-saving and environmentally friendly, but also enters the room with high-quality diffused light.

Moreover, the reason why this product of Aoxing is called intelligent lighting system is because it not only combines the fresh air system - it can purify the basement air while lighting it; It also automatically stores light energy, and the storage capacity is very large.

Even on rainy days, as long as the stored light energy is not depleted, the energy source continues to bring natural light to the basement.

In other words, the air in the underground castle is now fresh and bright as day.

Xu Yin didn't say much, and took the lead in drilling into the entrance and exit of the bunker.

When she designed the drawings, she carefully thought about three places to make the entrance, namely the back of the door of the stairwell, the jungle with the intelligent lighting system, and the corner of the utility room behind the kitchen.

After entering the three entrances, you need to go down a staircase, and then pass through a narrow ramp, and then the real entrance to the bunker - an iron-gray stone door.

Ning Jin saw Xu Yin entering, worried about her safety, and hurriedly followed.

Both of them went in, Xu Dong and Xu Xi were still hesitating, and they also went in.

"It's so dark! Yin Yin also said that it was not dark. Xu Dong muttered quietly, groping his way forward, "Brother Ning, you go slowly!" ”

Xu Xi tugged at the hem of Xu Dong's clothes: "Dongdong, I'm afraid." ”

Xu Dong: Actually, I'm scared too.

But before the two of them took a few steps cautiously, Xu Yin, who was running on her short legs, had already come to the stone door, stretched out her hand and pressed on the doorknob, the stone door slowly opened, and natural light poured out.

"Wow-"

The little radish heads behind her, including Ning Jin, all widened their eyes.

"It's so bright! It's as bright as the outside! ”

"Is there a sun growing here, too?"
