Apocalyptic natural disaster, stock up with billions of supplies to survive

"Are you testing me, little girl? This is a friction nanogenerator."

"Theoretically, any behavior that generates friction can generate electricity, such as the soles of shoes when walking, the tires of cars when driving, and other physical movements."

"In addition to physical motion, there are also natural motions, such as raindrops, hail, and snowflakes falling from the sky!"

"It is obviously unrealistic to generate electricity using physical motion, and the only natural motion with a lot of friction is snow, so this power generation device generates electricity using the friction of snowfall."

"In fact, this method of power generation was proposed before the end of the world, but it still has some problems."

"The reason why I said the person who built this generator is a genius is because he modified the circuit and some accessories of the traditional friction nanogenerator so that he could collect enough current normally."

"I don't have the ability to modify a generator like this genius, but give me 10 days, no, 7 days, and I can copy one!"

Tong Tianheng was not angry when he heard Han Ying's words, but patted his chest and made a promise.

"Okay, I'll wait for you for seven days. The deputy base commander has already gone back. I'll have someone send you back with the equipment. I'll try to see your results in seven days."

After saying that, Han Ying left the warehouse with Lu Yuan, and then called Liu Hefeng to ask him to arrange a car to take Tong Tianheng back.

After the two farmers left, Tong Tianheng touched his nose. Why did he feel that these two farmers didn't seem to like him very much?

Ever since he came here, this little girl has been testing his abilities.

But considering that these devices were brought back by these two people, it is normal to be hesitant to hand them over to him.

What I just said should make this girl feel more at ease, right?

It seems that I have to be more serious next time and try to copy it in less than 7 days.

Until Tong Tianheng left, Han Ying did not give Tong Tianheng the accessories diagram that Zheng Lin had given her.

Because Han Ying knew that he didn't seem to need it anymore.

After leaving the warehouse, the two went straight back to their igloo.

The snow houses of Qin Qinghai and Lei Minghu's families were about a hundred meters away from them.

The two of them went over to say hello to both families.

Qin Qinghai's house was the first to arrive and he found that there was no one in the snow house.

Han Ying guessed that the three members of Qin Qinghai's family should have visited Lei Minghu's home.

Sure enough, when the two of them walked along the passage of the snow house and knocked on the door and went in, they saw two families playing mahjong and chatting around the fireplace.

"Did you just get back? Have you eaten in such a cold day?"

Seeing Han Ying and Lu Yuan suddenly appear, everyone showed surprise on their faces, and He Xiu hurried to show concern for them.

"I've been back for a while. I talked to Captain Liu and the others about something. I was just about to go back to eat."

The two of them hadn't had dinner yet, but they weren't very hungry, so it would be very convenient to get some food from the space after returning.

"Why are you going back? I made a lot of dumplings a few days ago and froze them in the refrigerator outside. I'll cook some dumplings and you guys can just make do with them."

Upon learning that Han Ying and Lu Yuan had not eaten yet, Wu Tingfang immediately stood up and went out to get some dumplings.

Lei Minghu made a natural refrigerator with snow water. He dug a big pit outside the igloo and placed the natural refrigerator inside the pit.

He also made a lid for the refrigerator and covered it when it was not in use. Soon the snow covered it and people outside couldn't see it.

Qin Qinghai and his team also made such a refrigerator. During the days when Han Ying and Lu Yuan were away, Lei Minghu also made one for them, just outside Han Ying and their snow house.

"That's fine too. I'll trouble you, Sister Wu."

Han Ying did not refuse Wu Tingfang's kindness.

On weekdays, the two of them often gave good things to their two families. The two families had always been worried that they could not find a chance to give her and Lu Yuan something in return, so when they occasionally invited them to dinner, the two of them did not refuse.

Hearing that Han Ying did not refuse, Wu Tingfang happily went to the refrigerator outside and took out a large bag of dumplings.

Then everyone cooked dumplings in a pot while roasting a fire.

While cooking dumplings, Lei Minghu told the two about the farm's situation during the days they were away.

It wasn't a big deal, we just caught several groups of people who wanted to dig holes in the ground during the dark night to steal food.

Of course, there were also cases where they were not caught, and some potatoes and sweet potatoes that were not fully ripe were dug up.

Apart from these, there is nothing else major.

It seems that the previous act of burning the thugs alive worked, and there have been no home robberies in the base recently.

But everyone knows that this kind of peace will not last long.

So everyone became more careful, and every household was looking for steel everywhere to reinforce their doors and windows.

Those who are able are also looking for official funds to purchase steel bars and cement to build the wall.

Although the wall cannot completely stop thugs who attempt to break into people's homes and rob them, it will at least take them more time and energy to enter their homes.

Maybe the thugs thought it was troublesome and started robbing other people's houses instead.

And even if the thugs were determined to rob them, the wall could hold them off for a while longer.

In addition to steel and cement, people at the base were also looking for bells everywhere, hanging the bells on ropes and then tying them to walls, windows and doors.

This way, when thugs come in and accidentally touch it, it can send out a warning, giving people at home more time to react.

Those who couldn't find bells also ground some iron sheets and made simple bell-like things.

As long as it can issue a sound warning when it is accidentally touched, it will be fine.

In addition to these, the base is now calling on everyone to get their bodies moving.

You don't need any special moves. Just practice hitting with a wooden stick like a baseball bat, or chopping with a kitchen knife. Practice at least two or three hundred times a day.

Practice these moves well and become familiar with them, so that if thugs really break into your home and rob you, you will at least have some ability to deal with it.

Let everyone not worry about expending energy and becoming hungry.

Because only when you are alive can you feel hungry!

So now everyone in the base is as excited as if they had been injected with chicken blood.

Apart from going to work every day, everyone stopped bragging and chatting, but stayed at home, practicing by swinging a wooden stick with a big end and a small end.

A few people were chatting about what had happened at the base in the past few days, and the dumplings were soon cooked.

Wu Tingfang took out a stainless steel bowl used for dishes and served a large bowl to each of Han Ying and Lu Yuan.

The portion is quite large, equivalent to two and a half ordinary ceramic bowls, and two people can still finish it.
