Rebirth after the end of the world: I won by relying on the system

"Ha ha..."

Yundou twitched the corners of his mouth numbly, and frantically searched for the hair rope while looking around and giggling.

By North!

She finally knew why everyone here wore hats!

She also blamed herself, thinking that the hats of protective clothing and raincoats were too stuffy, so she took them off as soon as she came in.

There was a layer of black insulating stickers on the floor, mixed with her black hair rope, Yundou couldn't find it with sour eyes.

"Don't look for it, the ground is not safe."

Yun Kemin picked up his sister, took off the hat on her head, and put it on for her.

He took Yundou behind him, blocking the sight of the people around him, and his handsome short hair flew up silently.

"...Forget that I didn't treat you in vain..."

With her tall back covering Yundou's figure, she straightened her hair neatly and stuffed it all into the hat.

Smelling the scent of bath soap from his younger brother, Yundou suddenly got the point of Bailian's fascination with him.

"Cough cough."

Coughing twice tactically, Yundou looked at his brother who had fried his hair, and a trace of warmth flashed in his heart.

Trying to suppress her smile, she pointed to the big guy in the middle and said, "Is this the result of your research for half a month?"

Yun Kemin took a few steps forward, brushed his hair casually with his hands, and rested his arms on the railing.

With a clean and handsome face, it really looks good with any hairstyle.

With a certain confidence in his eyes, he said with some joy: "This is a lightning transformation machine."

"We have studied it for more than half a month. After the nationwide and global power outages, we have already begun to invest in manpower, financial resources, and material resources."

Yundou squinted his eyes halfway, and looked up at the lightning rod standing amidst the wind, rain, and lightning.

It is hard to find lightning rod materials that can resist the corrosion of acid rain, the invasion of high temperature, and the destructive fire.

The Nanquan government is spending its old capital to do big things secretly.

"In less than a year, such a powerful invention can be produced, which is also great."

Yundou looked at his younger brother's slightly tired eyes and patted him on the shoulder encouragingly.

But Yun Kemin shook his head, and touched Yundou's forehead with his knuckles.

"Sister, let you study more, you go to feed the pigs every day."

"After half a year and a year, how could it be possible to develop such a large and difficult device."

He has already filled out the mocking attribute of his sister.

"To be precise, scientists have been studying the technology of collecting lightning energy for daily use for decades, but now Nanquan Research Institute has made some small achievements."

"The most important thing is that this proposal is the last major material question written on the paper during my interview."

The original question is: In the absence of wind, fire, water and other power generation resources, is there any way to meet the normal electricity demand of human beings?

Lasted a whole day, nearly 200 people took the written test and interview, only he and another female doctor passed.

And his answer sheet is now presented in front of Yundou.

Electric sparks flickered in Yun Kemin's dark pupils, like a little hope in the endless darkness of the end times.

Yun Dou stared at the tiny lightning in the sky, and for the first time without any teasing tone, sighed: "It was also born by the same mother, why are you so awesome?"

Yun Kemin lowered his head and shrugged, slightly hooking the corners of his lips.

In his heart, the elder sister who is afraid of killing the enemy with a gun and crossbow is even better.

He was very happy to be praised by Yundou.

"After that, will Nanquan not be short of electricity?"

"Or, this electricity is also divided into blocks, divided into people, and divided into high prices?"

Yundou still cares about electricity. The solar power generation at home is really not very effective in polar nights.

If there is another source of electricity, a large electricity consumer like Yunjia can also relieve a lot of pressure

In the past, the villa area had been powered on for two or three hours at night, allowing her to get up in the middle of the night to recharge the battery box.

The electricity consumption at home can also maintain normal operation.

But after the magma raged, many power lines must have broken down.

Yundou was worried about how to plan the electricity consumption for the next polar night. He did not expect that the government would have such a big breakthrough in electricity production.

This is probably the wonderful feeling of giving a pillow when you doze off.

"This is just a low-level lightning conversion device. We can only convert 300% of the 50-degree electricity carried by a lightning bolt and then collect it."

"And, like just now, after being attracted by the local electric field here, it must be struck on the lightning rod."

Yun Kemin dragged his mandible with his left hand, frowned, and looked at the research institute's painstaking masterpiece with some dissatisfaction.

"For the time being, there is no way for all residents to use it."

His tone was a little frustrated, feeling deeply helpless.

"According to the probability of acid rain and lightning, we should be able to collect a lot."

Yundou reckoned the rainy days in his previous life, and the lightning and thunder that accompanied them almost all the time.

Moreover, in the case of snow, there is also thunder and lightning.

Even if it is 50%, the accumulation of less makes more, and that is not a lot.

The electricity needed to purify water and mine groundwater should be available.

Yundou swayed slightly, and bumped into Yun Kemin's shoulder sideways.

"I think, in addition to upgrading its conversion ratio, you should also consider other factors."

She cleared her throat, looked at the parts that were tightly stuck together, and reminded seemingly inadvertently: "If, due to some unexpected reasons, the defense area is hit again, or we have to move out of Nanquan."

"This device costs so much money, it must be able to be removed."

Yun Kemin was obviously stunned for a moment, the device research was in a hurry, and everyone really didn't have time to consider this issue.

"Sister, you are right!"

"If it reaches a detachable state, maybe some small devices can be made and placed in various residential areas."

"As long as there are enough molds, countless possibilities can be assumed!"

He turned his head, and suddenly looked at the glowing Yundou with his eyes burning.

"Sister! My dear eldest sister!"

Yun Kemin's sudden enthusiasm made Yundou take two steps back, tilting his head to express his doubts.

I saw his thin lips open and close, "Can you lend me some money?"

"Not much! Just a little money!"

...The smile at the corner of Yundou's mouth froze, and he tactically smoothed the broken hair by his ear.

"How much do you want to borrow?"

Yun Kemin's eyes lit up, and he stretched out two fingers.

"20?"

He glanced at Yundou in disgust.

"200?"

The corner of Yundou's mouth twitched twice, this child is really not in charge of the family, and he doesn't know how expensive oil and rice are.

However, as her younger brother, what is it to give 200 electronic coins...

"Of course not, it's 2000!"

What a big head ghost!

2000 electronic coins!

It's not a younger brother, it's a gold-swallowing beast!

Yun Kemin ignored Yundou's cracked expression, and began to mutter, "Sister, I need countless molds to disassemble such a large device."

"Now I have nothing to worry about, and the project funds are all spent on this thing. If we want to make changes, we need to advance money to make molds..."

"If you support me so much, you can definitely..."

Yun Dou raised his hand, stopping his sudden enthusiastic words.
