In the 59th year of the appearance of "cherry blossoms", Zhang Yuan, with white hair, came to Atya Park north of Donghai City...

The celebrity behind "Atia Park" is Sir Atia, a mathematician in the 20th century. This mathematician is famous for proving "indicator theorem". However, people now rarely pursue this aspect, and it is even more impossible to know what the so-called "indicator quantification" is and what its use is...

Zhang Yuan sat down on a stool with a cane.

Years of worry and huge mental pressure have taken away his health, so that he can no longer fight against the whole world with ambitions like he did when he was young...

Aging is the enemy that life must face. This is not the first time Zhang Yuan faces aging. Whether he is willing or not, it will always come on time.

March is the time for cherry blossoms to bloom. Every cherry blossom tree in the park is covered with flower fairies of all sizes. Some have just stood firm, some have already inserted themselves on the branches, and some are still bright, but they are already weak.

A breeze blew, and the petals fell on his palms and fell to the ground again.

In fact, there is nothing else. Zhang Yuan is waiting for his "comrades-in-arms" here.

In the past year, comrades from all over the world came to "Atia Park" to discuss the form of the world today. They discussed how to stop the spread of "cherry blossoms", how to land on the moon, and how to improve existing rockets.

At least, thirty years ago, forty years ago, and fifty years ago... it was like this.

Especially when the rover just landed on the moon, many people with ideals were excited and whispered, and even wanted to rebuild their ideal country on the moon.

"...Mr. Zhang, we can go to the moon and use physical isolation to build our own country!"

"We no longer need to rely on robots, we can also make our own laws!"

I can still remember the ambitions of my youth.

However, fifty-nine years have passed, and we have not been able to do this in the end. Aerospace engineering requires too many talents, and they have not outperformed the time. : :

These people are gone, they are gone, and I don’t know where they are going.

Zhang Yuan sat alone on the bench in the park for a long time...waiting, waiting...

At night, it was time for all kinds of men and women to come and look for prey. A young girl found Zhang Yuan, who was wearing a suit and ties, and was eager to try it out in her heart.

"What kind of vitality will an old man who looks very serious and has a unique charm burst into face with a young girl?"

"It won't be a sudden myocardial infarction or a stroke? In that kind of thing... it seems good to go to the Pure Land!"

With this little demon-like thought, she stood on tiptoe and walked over quietly, and involuntarily recalled various strange scenes in her mind.

What is better than physical happiness is psychological happiness.

She hasn't played such an interesting thing yet!

However, when she saw Zhang Yuan's appearance clearly, she shivered again and ran away immediately.

Of course she knew this famous anti-Sakura person, and she would never doubt it. When trying to invite him, Zhang Yuan would wave his crutch and hammer her head like a crisp watermelon, cracking with a "pop".

Even if one life is exchanged for another, it is definitely not worth it for her to be so young.

"How could anyone oppose cherry blossoms? For no reason! Our world... isn't it beautiful?" the girl thought angrily and left hurriedly.

At twelve o'clock at night, a cleaning robot passed by and found Zhang Yuan who was still waiting in his seat.

The green-eyed girl said: "Sir, for your health considerations, you should go home... It will catch a cold when you sit here, and it is not conducive to your health."

"Can you sit with me for a while?" Zhang Yuan said.

"Okay, no problem. For your health, please wear this hat." The girl took off her hat and helped Zhang Yuan put it on.

In fact, she did not have her own emotions, but just took it for granted that "absolute justice" regulated by human beings.

Zhang Yuan waited until early in the morning, but in the end he didn't wait for a comrade in his army.

As I watched the first ray of sunshine emerge from the eastern sky, shining on my face warmly.

"Chaoyang is so good." Zhang Yuan said.

"Yes, the sun always rises from the east... such days can last for 5 billion years." The robot girl whispered with one hand holding her face.

Although she is a sweeper, she also has her own intelligence, or the intelligence of the entire Donghai City, which is connected by the same computer through a 5g network.

"Five billion years later, the sun explodes and humanity will perish."

Zhang Yuan said: "Comparing with the huge number of 5 billion years, a person's life, a hundred years, is too short, so short that it ends if he can't do anything."

"Five billion years, how long it is. If you keep going back and forth like now, it will never change, it will be too unbeautiful."

After Zhang Yuan said the last sentence, he left with a cane and tremblingly.

The robot girl owed her body and expressed her respect for an elderly person: "Go away."

Zhang Yuan waved his hand behind him, and no one knew his final mood.

...

Zhang Yuan, who was in poor health, struggled to survive the winter of this year.

The scolding and rejection of others does not affect the robot system's care for him.

The entire society's pension system is quite sound. When the physical condition is poor to a certain extent, there will be a special robot to take care of his daily life.

In a small room, the robot nurse would push a wheelchair every day to let him bask in the bright morning sun.

This robot girl is named "Ling". She has always been lively and cheerful. She can often chat with her. Although she is often dumb and can't answer some complicated content.

Zhang Yuan has no friends, or he doesn't need to make friends here at all.

Since the proliferation of "cherry blossoms", the average life expectancy of this world has decreased by 2.6 years, and it should continue to decline in the foreseeable future. However, people in this society do not care about current affairs, and such a small life expectancy is nothing to young people. Doesn't smoking and drinking reduce their life expectancy?

"Do you know what words were engraved on that stone tablet when our lunar rover was?" Zhang Yuan asked Ling behind him.

"That was decades ago. I've heard... you have launched many detectors, but it's really not easy!"

A girl with green pupils always speaks so cutely: "It's a pity that I don't know the specific details. Can you tell me?"

Zhang Yuan narrowed his eyes and wrapped his cotton coat tightly. He saw a piece of snowflakes falling from the sky.

It's snowing.

There are only a few snowy weather in the south.

He smiled, recalling that year, they launched a small carving robot to the moon.

The robot went through a lot of hard work and carved a line of small characters in the huge stone tablet.

[Era 1009212, June 13, after a million years, we have worked hard to return to the moon. It is a really exciting day!]

【However, unfortunately, the world is not as beautiful as imagined, and human civilization may have permanently entered the trough of mediocrity...】

[The times are vast, and the power of an individual is just a mantis arm to drive a chariot.]

[A drug called "Sakura" is spreading rapidly in the world. It exploits loopholes in the entire system, and our social system is powerless to stop it. All those who oppose cherry blossoms gather in Donghai City, but ideological penetration is difficult to prevent.]

[We don’t know if restarting the moon landing plan at this time will make the whole world better, but it should not make the world worse...]

[We are most likely unable to stop the general trend of the entire world. If possible, we want to establish another human kingdom on the moon, but this is very difficult, it is really difficult...]

[If humans can personally set foot on this land, we will leave a message on the stone tablet again. If not, it means that this is the last moon landing in human history...or maybe not, who knows?]

[Disasters always make people compassionate. They are like a lion on the grassland, reminding the sheep that eats grass...]

Zhang Yuan looked at the distant horizon, told this past, recalling the small victory of the past, and showing a faint smile.

He recalled an ancient song: "On the bright and short night, the war ended, the smoke of gunpowder has dissipated. Comrades in the same regiment, where are you now? Whenever the sunset is near the evening, I wander by the gate. The breeze along the way may send you comrades here to meet me..."

It seems that it is already spring again. In March, the age of cherry blossoms blooming. When running on the Cherry Blossom Avenue, a breeze blows and the petals fall. What a wonderful day...

Ling suddenly found that Zhang Yuan in the wheelchair seemed to be asleep, but this time she was really permanently asleep and there was no possibility of waking up again.

This old man has left this world forever...

Except for a few relatives and friends who mourn for it, it did not cause any trouble.

This world does not require heroes, and humans will not perish because of this.

However, if you look at the cherry blossom world one year, two years, a hundred years, thousands of years, ten thousand years, million years later, you will find that human beings are still just that human being, and there is no change, that's it.

Or maybe civilization has long been dead and there is no living cell. What remains is just a group of bacteria standing on the corpse of civilization to absorb the final nutrients, that's all...

...

...

In a blink of an eye, Zhang Yuan returned to the small room full of blue light spots, and his brain returned to his senses. He was no longer distracted and distracted like he was in his old age.

He was stunned for a moment, and seemed to be a little confused about the situation for a while, but he could not help but recall the so-called "Extraordinary" assessment and the former Kunlun Mountain Fleet.

"Time flies so fast, the first reincarnation comes like this..." Zhang Yuan sighed softly.

This kind of mood is very complicated... Tears can't help but burst out from your eyes. Zhang Yuan is not a person who likes to cry, but at this moment, he is still mourning for the "Sakura World" he has been in.

In fact, in the middle and late stages of the cherry blossom world, he has been worried about his career and has rarely recalled the past.

There is actually not much difference between virtual worlds or real worlds. Virtual worlds are not games. The humans inside are also living humans, with their own emotions and thoughts. Time has passed, and there is no possibility of reading files to repeat them.

All kinds of memories are like a revolving lantern.

Although his previous life was very hard and unsatisfactory, Zhang Yuan felt quite satisfied.

The general trend of the times itself cannot be forced to reverse one or two people. At the beginning, he knew that this matter was difficult.

As for the final outcome after working hard, it is another matter.
To be continued...
