"In fact, the profits that big companies make on solar panels are not very high. The interest rate on the bank's loans is also not high. They just make a little bit of hidden maintenance and the difference in the price of electricity......"

"These solar panels can be regarded as a kind of folk welfare, and they are also a means of energy promotion."

"The main profit, of course, comes from ...... batteries and other derivative products. ”

The public network power supply at night is relatively expensive, so the battery has become a commonly used electrical appliance, and the price is a little higher, and ordinary families can afford it by gritting their teeth.

And the battery is also replaced more frequently, almost every five years, unlike solar panels, which can be used for one or two decades.

This phenomenon of every household using a battery will only appear in the post-oil era...... Without long-term energy stability, everything changes.

The Big Bang of Technology?

Life is getting better?

Inexistent.

Throughout the history of the Yufu civilization, the time when there was oil and coal, experienced several industrial revolutions, and the rapid development of science and technology, it was already the happiest. However, people at that time would never be satisfied, let alone cherished.

They look forward to the arrival of the singularity era, to eternal life, and to the future that can solve all problems. Even, some people want to freeze themselves and resurrect them in the future to solve the problem of longevity.

Unfortunately, the future is destined to disappoint them.

While the two were talking, they sang a small tune quite emotionally.

For them, it's just a passing passerby, and it doesn't matter if life is good or bad.

Even the races are different, and there will be no overflow of sympathy in the heart of the Virgin, only a few sighs because of some commonality.

The starry sky, the smell of earth, and the fragrant smell of vanilla seem to be memories of a long time ago.

"There's a feeling of running out and cheating when you're young."

"In some villages, the men and women of the village like to hide in the haystacks...... There are still ...... in our time on Earth That kind of story, all kinds of dog blood, what red apricots are out of the wall, sister-in-law and uncle. Yu Yifeng smiled, and at the same time another hand reached into her clothes.

"Oops!" Yuriko squealed in a low voice and clapped his hand again: "What are you doing?" ”

Yu Yifeng retracted his hand and said with a smile: "Sometimes, I feel that this place is okay." I miss it. ”

"But it's just a few momentary memories, what about you?"

"I don't feel anything...... Not as sentimental as you. ”

She said lightly: "It's not as interesting as the laboratory, and the food here is weird...... It's a little hard to get used to. ”

"Our memories have just been beautified by time, and now we feel so-so, because of a feeling that supports us. After staying a few more days and feeling down, I am guaranteed to feel quite bored......

"Remove the material condition...... Don't you think it's troublesome for people to be intrigued? It's still good for us to be there, relaxed, peaceful, free, and everyone is full of energy. ”

"I still like ...... Live simply. ”

Yu Yifeng nodded and said, "So...... Let those nostalgic old guys come and live for a while, and when they get bored, maybe they can change the subconscious thinking of the home planet. ”

"We are an interstellar civilization, not a low-level civilization that is willing to stay on one planet......"

It's a large expanse of farmland with a tall, unknown crop, a bit like sorghum, surrounded by dense stacks of haystacks.

There are also a variety of dense dwarf shrubs, called "lasso", which grow very quickly, are a good supply of firewood, and can also produce something similar to rubber.

Scientists are investigating whether the plant could be introduced into the Noah ecosystem, as new humans are also less organic.

The cries of various insects are unusually loud in the open field.

The two of them wander aimlessly along the road and enjoy the simple time of two.

Just walking like this, Yu Yifeng's ears suddenly moved, and he heard a strange sound, mixed with the sound of insects, which was not very clear.

He listened carefully for a while, and seemed to have found something remarkable, "Look, I guessed it! ”

He pulled the girl and walked gently, as if he was a thief, tiptoeing, and his palms were even a little sweaty.

Nervous, nervous.

Even the heartbeat is slightly faster.

The two of them didn't know why this was happening, but they did it subconsciously, and there seemed to be a hazy sense of stimulation.

"Do you hear that? Did you hear that? After walking a distance, Yu Yifeng attached to her ear and smiled with a strange expression: "This way, this side ......"

Yuriko listened intently, her face slowly turned red, and she only heard a very heavy gasp from a man and a woman, quite happy and quite depressed.

It's as if it's suppressed like this, and it's even faster to live.

She finally understood what that strange sound was......

It's really right, there are really people hiding in the grass! Sometimes I couldn't help but suppress it, and I screamed out directly, my voice was accompanied by trembling, and the people with four kidneys were really powerful.

The two of them listened quietly for two minutes, Yu Yifeng felt more and more sweat in his palms, and he had unconsciously attached it to her and hugged her.

And the other party's body seems to be very hot.

"Ahh Let's go, what's so good about this. Spooky fun ......"

"Low-grade fun." She regretted coming here a little, she was so hot that she wanted to go back with Yu Yifeng, but she stepped on something with a "click......

It's a twig.

Hearing this voice, the two passionate gasps immediately stopped, as if the rats in the cave were startled by the cats outside.

There was silence in the clearing, save for the whistles of various insects. It's just that most of these very loud-sounding insect calls are also courtship.

Yu Yifeng suddenly had a whim, coughed heavily, and then bent down and threw a piece of mud into the field with a clever stroke.

"Click", a woman couldn't help but scream, and immediately suppressed it. Immediately afterwards there was the sound of a man scolding, and all kinds of mud were thrown out indiscriminately, but he didn't dare to make a big deal about it, just tossing around in the field.

The girl next to her smiled like a red apple, but unfortunately under the faint moonlight, she couldn't see it very clearly. Even though her usual expression was quite cold, she was very happy at this time, and the two of them held hands and ran back quickly.

This kind of bullying fun, bringing a long-lost sweetness, will never exist in the Noah.

In his own civilization, how can Yu Yifeng bully others, he rarely even jokes...... There are also few facial expressions, and you have to do things at a glance.

They ran to their rooms in good understanding, laughing happily at each other for a while, and then fell silent again......

Yu Yifeng began to inspect the entire room suspiciously.

"What are you doing?" She asked with her legs pressed together, a little confused.

"It's always good to see if there's monitoring and be careful...... If we get photographed, the two of us will be out of luck! ”

He carefully searched the room, with a personal characteristic, even the sockets of electrical appliances and found nothing unusual.

Now it's finally easy.

Assume...... This rural family should not be able to afford such things as cameras.

Yu Yifeng couldn't wait to pick up the girl......

Counting the hibernation time, they are hundreds of years old couples, but they still look very young, and they have enough enthusiasm and vitality.

Yu Yifeng only felt that the other party was extremely hot today, the outside was like this, and the inside was the same, like a volcano full of magma.

I don't know if it's my own psychological reasons, or if that's the way it is.

In short, he feels good......

"Don't make a sound, it will be heard...... This kind of place is not very well insulated. He whispered.

This kind of depression in silence does seem to be quite happy......

Superhuman sensitivities are too strong, and there are actually pros and cons to some things, and some things will feel greater joy, which is more intense than ordinary people.

But too much joy also has certain negative effects, and sometimes it can be very quick to surrender, especially if you are inexperienced at first......

In order to avoid this embarrassing phenomenon, Yu Yifeng had to find some special methods.

For example, think about complex issues to distract yourself. In this way, you can solve the problem of being too sensitive......

I don't know how long it took, but he felt a little unbearable, and immediately began to calculate a calculus math problem in his mind.

Ever since he learned the technique, he's been enjoying it. Although I already know the answer to that math problem, the intermediate derivation process still requires a lot of mental effort.

Of course, the girl has no such troubles, so she will soon fall into a state of mental confusion......

After another while, Yuriko suddenly covered her eyes with her two hands, made a very strange movement, and trembled slightly...... This kind of physical feedback was quickly known to Yu Yifeng, and he breathed a long sigh of relief in his heart.

Okay, finally solve the other party, don't be stupid to do the math, but let's take a break first......

And so they held it.

"17,789 times, it's been so many years." After a while, she whispered.

"Ah...... What the? You even counted the times? Yu Yifeng was dumbfounded.

"So many times, I can support a ship, and I can't even give birth to a child......"

"How can you say this, it depends on luck......

Yu Yifeng did the math in his heart, counting such a long time, this frequency does not seem to be high.

Everybody's so busy.

However, the quantity is a little less, and it is good to make up for it with quality.

He suddenly thought of a serious question, and asked, "After the field investigation, I think that the integration of the two civilizations is impossible...... Originally, I wanted to solve the problem of our small population through this planet, but now I can't do it. ”

"After all, the quality of the population here is here, and it's hard to change. I can't bother to spend another few hundred years here educating an unrelated race. In such a long time, our own population has gone up. ”

"If our people get in, they're immediately scattered...... A civilization is difficult to go up, but it is easy to go down, and philosophical gravity exists after all...... The fall was spontaneous. ”

"Hmm...... Well, you're right. ”

"Therefore, if you want to travel here, you must at least have a more mature worldview, and children are not allowed. There are so many drug-addicted, movie-watching, and gambling people here...... It takes at least an adult over the age of forty to withstand the shock. The 40-year-old probably graduated from school...... Alas, I don't know if it's mature enough. ”

With the increase of knowledge and the increase of life expectancy, it is natural to extend the study, and the age of 40 is the normal time to leave the school gate.

"I wonder what else this planet is used for besides tourism, nostalgia, and life research value? I thought about it, it doesn't seem to have much development value......" Yu Yifeng took a heavy breath, not knowing whether he was depressed or quite satisfied.

It seems that the cultivation has reached the critical point, and he hurried ......

If you want to quickly transform the entire civilization, it is impossible, and the development of a civilization to this level cannot be promoted at all without relying on very, very strong external forces.

Do you go red? Racism? Please, these things have already appeared in this civilization, and even if they happen again, they will not bring a mental impact to the numb minds of ordinary people.

Unless...... Send them a large nuclear blaster.

"Hmm...... This planet can be used for social practice...... There are many ways to use it. "There was a warm heat in my ears, and it was a little itchy.

Yuriko thought for a while and said seriously: "Let us civilize, those disobedient and not very motivated children come here to endure hardships." I've heard that some children have lazy thoughts in their ideological evaluations, right......"

"It can also be used for military training, there are all kinds of neutral areas here, there are all kinds of drug lords and the like, let's send our soldiers there secretly to practice...... The actual combat on the frontal battlefield is the most experienced! ”

"It's a good idea, it can increase the actual combat experience! After passing the actual battle, at least it will not become a soft-footed shrimp on the battlefield. Yu Yifeng nodded.

"It's okay...... Let the energetic young people try to transform this society. This kind of social transformation can be regarded as a kind of fun in the era of great industry...... It is also possible to increase our sociological experience. Transforming a corrupt civilization into a dynamic civilization should also be a rewarding thing. It doesn't matter if it succeeds or not. ”

“…… Also, ah, look for the kind of crazy scientists who have no talents, and the kind of crazy scientists who have never met talents, the estimated probability is very low, but it is also possible. With so much use, how can it be said that it is useless? ”

Hearing her say this, Yu Yifeng was stunned for a moment, he agreed very much, but said in his mouth: "Are you thinking particularly active at this time?" Is it okay to focus a little bit? ”

……
