In a blink of an eye, the four children have been living part-time in Central City for half a year.

 In the first two months, because the floods had not receded, the three protective doors in the central city’s living area were always closed.

In the third month, the flood receded a little. After ensuring that surface water would not flow back, the government began to organize young and capable volunteers to follow the army in rescue and disaster relief operations.

 They need to move animals, salvage human or animal carcasses and burn them in time to avoid causing plague;

It is also necessary to salvage vehicles, furniture, and electrical appliances that have drifted out of residential buildings and factories. After repairing them, the usable ones will be transferred to the second-hand market, and the unusable ones will be scrapped and recycled. In particular, it is necessary to pay attention to whether there is food in these items.

It was nothing in extremely cold weather. Now that the temperature has risen suddenly, a large number of bacteria can easily breed after food spoils and rots.

Other people still live comfortably in underground cities with moderate temperatures.

Xu Yin once had the idea of ​​​​sneaking out to see what was going on outside, and by the way go back to the bunker of the orphanage to see how the little animals were living there.

However, to enter and leave, you need to swipe the wrist chip and face. Even if she uses stilts, wears a loose coat, and activates random skills to disguise herself as a strong man in his thirties, the first protective door will be able to stop her:

“Didi—warning! Warning! Xu Yin, female, eight years old, underage..."

 No idea at all.

We can only give up and hope for the day when the floods recede soon and people can freely enter and exit the central city.

 Happily, the adopted rutin chickens started laying eggs when the volunteers braved the scorching sun and heat to salvage supplies from the floods.

Although they are small, they can't bear to lay eggs every day. The two rutin chickens can harvest two eggs every day. The four children take turns to feed them and eat one every other day. In addition, the subsidies received from the logistics department and the hidden eggs in the mountain climbing bags when they come here The can of milk powder in the bag is quite nutritious. At least since I moved into Central City, my height has increased by a few centimeters.

 In the past six months, the vegetable plots cultivated by myself have been harvested twice in the short growing season, and the long growing season has also reached the harvest period. Therefore, it has been busier than usual recently, but I am very happy.

The Logistics Department’s recent subsidy to minors and the elderly included an extra tomato and a bunch of cowpeas, but it’s thanks to their efforts!

“Grandpa Liu said he would reward us!”

　　While eating in the canteen at noon, Xu Dong was very happy gnawing on the dry corn buns.

"What will we be rewarded with?" Xu Xi looked forward to it, "Something delicious or fun?"

At this time, the radio in the restaurant rang, and the announcer's voice trembled with excitement: "Listener friends! Here is a piece of good news: after half a year, the floods have finally fully receded. Volunteers and the army have completed three rounds of elimination. Central City The protective doors entering and exiting the ground will soon be opened to citizens across the city..."

"Wow-"

Diners cheered and expressed that they could no longer hold back and wanted to go outside for some fresh air.

 The four children looked at each other happily.

 “Can we go back to the orphanage?”

 “I miss Lao Bai, Marshmallow, and Little Cow so much!”

“Brother Ning, Yin Yin, why don’t we ask for leave in the afternoon and not go to school? Let’s go back to the orphanage!”

　　　…”

It is impossible to skip classes, not to mention that the temperature outside is already 40 degrees even late at night, and exceeds 50 degrees during the hottest part of the day. Who dares to go out without adequate preparation in advance?

Everyone said that they were suffocating and wanted to go to the ground to get some fresh air. However, before they could get out of the second protective door, they were forced back to the central city by the heat that hit their faces.

“It’s so hot! It’s going to bake us! It’s extremely cold at one moment and very hot at the other. Is there any way for humans to survive?”

 “How can you go out when it’s so hot? Don’t every household turn on the air conditioner and hide in the house so you can’t get out?”

"If you hide at home, you have to have a power plant that can provide electricity. How can you hide in the event of a power outage?" "Thinking about it this way, it seems that it is better to be extremely cold? At the worst, I can wear more down jackets and hide three or four floors underground. I can survive it no matter what." "

“What’s good! It’s only half a catty! When it’s extremely cold, the heating is also turned on on the third and fourth floors underground, otherwise what do you think?”

　　People gather together to chat when they have free time, and they no longer have the time to go to work or go to school.

　　Everyone was so happy when the temperature rose and the snow and ice melted, thinking that the extreme cold was over and the flowers were finally blooming.

Unexpectedly, the flowers bloomed, but failed again within a few days - how many flowers can withstand the scorching sun on this **** hot day?

“Did you hear that? The central city in the next province opened the protective door in advance due to the negligence of the personnel on duty, causing dirty water to backflow and causing infectious diseases. Now they are saying that some people who are not infected will be diverted to our place.”

“I’ve heard that too, but even if we can make room for them here, aren’t they afraid of dying on the road in such a hot day?”

“It seems that the Research Institute has invented a solar-powered ice pack. The stronger the sun, the more air-conditioned the ice pack will be. Carrying it is like carrying a refrigerator, so you are not afraid of dehydration, heatstroke, or heat stroke.”

“Really? Where can I buy one? I want one, I’m so suffocated in the dungeon!”

 The four children listened with great interest while having lunch in the cafeteria.

Since the floods have receded, everyone wants to go out but dare not go out because of the frighteningly high temperature. They often gather in the cafeteria to chat.

Let me ask you, who doesn’t like to hear gossip?

 Children are no exception.

No, Xu Dong was obsessed with it when he heard about ice packs: "How could there be such a dangerous thing?"

　　Xu Xi: "Is it made of ice? It must be cold when you carry it on your back, right?"

 “It won’t be cold when you go out! It’s very hot outside now.”

“That’s right! But such a good thing must have a lot of contribution value!”

As soon as Xu Xi finished speaking, an exclamation came from a few rows away: "You want five thousand contribution points? Who can afford it?"

Upon hearing the five thousand, Xu Xi happily blurted out: "We have enough!"

 After speaking, he quickly covered his mouth for fear that others would hear him.

As external vegetable farmers of the Planting Department, they work half a day every day and receive 600 contribution points every month. In addition, Professor Liu gave them a bonus a few days ago, which adds up to almost 6,000 contribution points.

Xu Dong lowered his voice and said excitedly: "Then we can buy ice packs!"

"Uh-huh!"

Xu Yin quietly drank the holy mung bean soup she received with her lunch coupon to relieve the heat, without daring to say a word.

She sent the drawings of the solar ice pack to Secretary Deng, for which she spent all her existing energy points.

If her friends are so angry that they put down their hoes and stop cultivating the ground and planting harvests, she will never get any energy points.

“Brother Ning, Yin Yin, we are back!”

 Xu Dong and Xu Xi were thinking about ice packs and ran to the logistics department to inquire about them as soon as school was over. They got home one step later than Xu Yin and the others.

"Aunt Liang from the Logistics Department said that there are no extra ice packs for sale right now because we have to catch up with the migrating troops first, but we can register first and have priority to buy when the goods are available. Xixi and I put the four of us together. Everyone’s name has been reported!” (End of Chapter)
