Han Yi spent half a month, experimenting back and forth more than a dozen times, making some major changes according to some characteristics of different time and space, and finally returned to the Norwegian town.

It was still drizzling here, and a drop of water had just fallen from the leaves in front of it. Looking down at the watch, there is no error in the time.

I took out the phone and dialed it, and asked carefully about the results of the changes I made?

The truth is that just like Evelyn, nothing has changed, business as usual.

Standing there in a daze, thinking about some of the most primordial things in the universe.

Since quantum theory allows time to travel backwards, i.e., time travel, on a microscopic scale, and he has proven this theory to be correct, a question arises that cannot be ignored - why have we never seen people from the future?

This is a paradox.

The explanation of this in the earth science community is that the past is fixed, and we look at the past and find that it does not allow for the kind of curl that is needed to travel back from the future, and that the future is unknown and open, so it has the required curvature, which means that any time travel is limited to the future.

The extraterrestrial civilization is suppressed by the level of planetary civilization, and the explanation for this is half a claw, but they mention the "end of time" in the theory of entropy.

Han Yi guessed that this should have something to do with the fact that the mechanical race could chase to the edge of the universe.

As for the facts, it remains to be seen that further development of science and technology will be achieved.

When his body felt slightly cold, Han Yi found that his coat had been soaked, positioned the atom to the New Zealand Satellite Launch Center, and then disappeared with a "whoosh".

......

Three days later, Orlando, Florida.

Orlando is a city in central Florida, located in a swampland, with dozens of lakes large and small in and around the city, and it is one of the best leisure cities in the world.

This year's World Kickboxing Championship was held at Park Lane in downtown Orlando.

Because the organizers of the conference are sponsored by "mystery people", they do not broadcast on TV, and in order to maintain order on the spot, there are no low-cost tickets for sale, and the grandstand tickets for 2,000 people have been sold to 150,000 US dollars.

VIP tickets are issued only for specific people and must be entered in person.

However, these are not important to Lu Menglin, she doesn't like to watch these fights and killings, if it weren't for Han Yi's possibility, she wouldn't have come.

She was now a hundred times more interested in the woman in front of her than in the Fighting Club.

"Hello, my name is Lu Menglin. ”

The corners of Evelyn's mouth were slightly hooked, revealing a very elegant smile, "My name is Evelyn Han." ”

The two women's delicate fingers touched, dipped and released, and then looked at each other, sparks splashing in their eyes.

One seemed to be sneering, "Han Evelyn...... It's really funny, why don't you just call Han Yi's family?"

And another one seems to say, "Better than you." Lu Menglin...... A strong local atmosphere came to the face. ”

After a pleasant greeting, the two quickly called each other "sister and sister".

Evelyn took the initiative to hug Lu Menglin's arm and said enthusiastically: "He has always told me that your sister is his right-hand man, and that you are smart and beautiful;

When we met today, I found out that he didn't even describe one-ten-thousandth of his sister!

My sister is not only beautiful and intelligent, she is simply a fairy, and any woman standing next to her sister will be eclipsed. ”

Lu Menglin said with a smile on her face: "Sister, you are too polite. If you want to say that I am beautiful, how can I catch up with you, sister, you have an innate graceful temperament, which dwarfs my sister and me;

Standing in front of you, I'm like that ugly duckling, lost in all my glory. ”

My sister laughed. ”

"My sister is too modest. ”

After complimenting each other, Evelyn glanced at the black suspender evening dress on Lu Menglin's body, and said with a look of pity: "My sister's dress seems to be adapted from the work of French designer Gavin Hozia, and it is an old work from last year, which is a little inconsistent with your overall glamorous and generous temperament!"

If my sister doesn't dislike it, I'll ask someone to help you redesign a new model. ”

Lu Menglin looked at Evelyn's "strong" arms, smiled and said, "Thank you, I really don't know much about clothing." But it doesn't matter, I'm usually busy with work, and I spend more time wearing professional clothes, and I'm not as delicate as my sister.

And I think it's a little bit more important to shape than clothes, so that the costume designer can be more comfortable with the design.

At this point, we can learn from each other in retrospect. ”

Evelyn smiled brightly, "Okay......"

......

Park Lane, Four Seasons Hotel.

Han Yi didn't know that the two women next door were about to "fight", and they were entertaining Wang Han and Kang Bicheng, who had just come from China, in the hanging garden of the hotel.

"Boss Han, how did I hear that you sponsored this game?"

"Hehe, almost. Han Yi laughed.

Kang Bicheng understands Han Yi's character, he said that it is almost the same, it must be a big difference, and even the opposite is true.

But I didn't get to the bottom of it.

After a few more laughs, Wang Han put down the teacup and asked seriously, "Boss Han, do you have any plans?"

"Why do you ask?"

"Well...... Wang Han said with a wry smile: "Last month, the relevant departments specially recruited me into the Office of the Global Strategic Situation Research Group as the deputy leader. ”

"Who's the team leader?"

"Boss of the Ministry of Defense. ”

Han Yi gave him a thumbs up and said, "Amazing!" and paused, "Why did you ask me that?"

Wang Han stroked two mustaches, which he had just stored.

After struggling for a while, he said, "I really don't want to go, I really can't help it." ”

Han Yi said: "Okay, don't sell miserably, say something quickly." ”

"Uh...... Boss Han, you also know that you are getting more and more weird now, and the relevant parties can't figure out what your situation is, and you refused to call and want to communicate with you, so send me to find out. ”

Han Yi asked Kang Bicheng, "What about you, what's your situation now?"

Kang Bicheng smiled and said: "I will hang up an identity and receive a salary of 10,000 yuan every month." Usually I am mainly busy with my accounting firm. ”

Han Yi raised his finger and shook it, and smiled at Wang Han and said, "This kind of empty salary should be fired as soon as possible." ”

Wang Han laughed and said, "Boss Kang, you heard it, don't look back and say that I'm not a buddy enough!"

Han Yi took a sip of the cup, put it down and leaned back on the upholstered chair, looked at the slanting sun on the horizon and said: "In my original plan, by 2023 at the latest, virtual reality technology will be realized in the world;

In 2025, new energy technology should be applied to all walks of life, and at the same time, biomedical technology should make great breakthroughs, overcome a series of diseases such as tumors, AIDS, diabetes, liver diseases, etc., and the average life expectancy should be significantly improved;

By 2030, the interstellar migration program ......"

With Han Yi's words, Wang Han and Kang Bicheng looked at each other, and they both saw the shocked looks on each other's faces.

"But then I found out that the plan couldn't keep up with the changes! No matter how good the plan is, when it comes to implementation, there will be all kinds of problems.

It's not that technology can't do it, but there are a lot of problems that go beyond technology. For example, entropy. ”

Han Yi briefly explained the entropy and continued: "The good things in the world are not strong, and the colorful clouds are easy to disperse and the glass is brittle!"

It takes energy to maintain a good state of affairs, and if there is no energy input, the good state will end.

After the Industrial Revolution, the development of human society has accelerated, becoming more advanced and orderly, but at the same time, the energy consumed has also increased exponentially:

If there is not enough hydropower, coal, oil, and nuclear energy. The greater the energy expended, the more entropy will be generated.

Therefore, human society has always been in a state of contradiction: while the whole society has become more orderly and tight, disorder and chaos are also growing in the shadows.

We just rely on a larger energy input to suppress the accumulation of entropy.

Increasing entropy is exploding in various ways: garbage pollution, global warming, desertification, PM2.5, species extinction, and so on!

We need energy to make the world orderly, but that comes at a cost.

With the current level of science and technology on the earth, there is no way to eliminate entropy and chaos, we just make some parts more orderly and transfer chaos to other areas. ”

Wang Han and the others understood half of it, but they didn't know what Han Yi wanted to express.

"Don't understand?" asked, Han Yi followed: "The more advanced science and technology, the more energy is needed, and when the contradictions accumulate to a certain point, war will break out."

Whether it's a local conflict or a third world war, it's not good for you or me. ”

Now Wang Han understood, hesitated and said, "But you can't stop developing because you are worried about the accumulation of entropy?"

"You're right. Of course, I can't afford to choke on food, so what I'm doing now is to shift the chaos to another realm......"
