In the fifty-ninth year of the appearance of "cherry blossoms", Zhang Yuan, who was full of white hair, came to Atia Park in the north of Donghai City......

The famous person behind "Atia Park" is the 20th-century mathematician Sir Attia, who is famous for proving the "indicator theorem", but nowadays people rarely investigate this aspect, let alone know what the so-called "indicator quantification" is and what it is for......

Zhang Yuan sat down on a stool on crutches.

Years of worry, as well as tremendous mental pressure, robbed him of his health, so much so that he could no longer fight the whole world with the ambition he did when he was younger......

Aging is the enemy that life must face. It is not the first time that Zhang Yuan has faced aging, whether he is willing or not, whether he wants it or not, it will always come on time.

March is the time when the cherry blossoms are in full bloom, and every cherry tree in the park is covered with flower fairies of all sizes, some of which have just stood firm, some of whom have already planted themselves in the branches, and some of which are still bright and weak.

A gust of wind blew, and the petals fluttered and fell on his palm, and then fell to the ground.

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

Every year today, comrades-in-arms from all over the world come to "Attia Park" to discuss the form of the world today, and they discuss how to stop the flood of "cherry blossoms", how to land on the moon, how to improve existing rockets, and other topics.

At least, thirty years ago, forty years ago, and fifty years ago...... It's all like this.

Especially when the rover had just landed on the moon, many people with ideals were enthusiastic about writing, scolding Fang Xuan, and even wanted to re-establish their own ideal country on the moon.

“…… Mr. Zhang, we can go to the moon and use physical isolation to build our own kingdom! ”

"We don't have to rely on robots anymore, we can make our own laws!"

I can still recall the ambitions of my youth.

However, 59 years have passed, and after all, it has not been possible to do this, and the aerospace project needs too many talents, and they have not outperformed the time.

These people are gone, gone, and don't know where they have gone.

Zhang Yuan sat alone on a park bench for a long time...... Wait, wait......

At night, it is the time when all kinds of men and women come out in search of prey. A young girl found Zhang Yuan, who was sitting upright in a suit and leather shoes, and couldn't help but jump in her heart.

"What kind of vitality will an old man who looks very serious and has a unique charm burst out in the face of a young girl?!"

"It's not going to have a sudden myocardial infarction, a stroke, right? In that kind of thing...... It seems like a good walk to Elysium! ”

With this little devil-like thought, she stood on tiptoe and quietly walked over, involuntarily conjuring up all kinds of strange scenes in her mind.

Even better than physical pleasure is psychological pleasure.

She hasn't played such a fun thing yet!

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

Of course she knew this well-known anti-cherry blossom person, and she would never doubt it, and when she tried to invite, Zhang Yuan would swing her crutches and blow her head - like hammering a crisp watermelon, it cracked with a "pop".

Even if she ends up exchanging her life for a life, she is definitely not worth it at such a young age.

"How can anyone object to cherry blossoms? Be all abroad! Our World...... Isn't it wonderful? The girl thought indignantly and hurried away.

At twelve o'clock in the evening, 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 reasons, you should go home...... Sitting here will catch a cold and will not be good for your health. ”

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

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

In fact, she has no emotions of her own, but only takes it for granted to maintain the "absolute justice" that human beings norm.

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

I watched the first rays of sunlight emerge from the eastern sky, shining warmly on my face.

"The morning sun is so good." Zhang Yuan said.

"Yes, the sun always rises in the east...... Such days can last for 5 billion years. The robot girl whispered with one hand on 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 the 5G network.

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

Zhang Yuan said: "Compared with the huge number of 5 billion years, a person's life, a hundred years, is too short, so short that it ends without doing anything. ”

"Five billion years, how long, if it keeps going back and forth like now, it will never change, it will be too bad."

After Zhang Yuan finished the last sentence, he walked away with a cane and trembling.

The robot girl owes a debt of respect to an elderly person: "You go. ”

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

……

Zhang Yuan, who was not in good physical condition, survived the winter of this year with difficulty.

The scolding and rejection of others does not affect the care of the robot system.

The pension system of the whole society is quite sound, and 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 pushes the wheelchair every day to bask him in the bright morning sun.

This robot girl's name is "Ling", and she has always been lively and cheerful, and she can often chat with him, although there are many times when she is dull, and some complicated content cannot be answered.

Zhang Yuan didn't have any friends, or he didn't need to make friends here at all.

The average life expectancy in this world has decreased by 2.6 years since the "cherry blossoms" flooded, and it should continue to decline for the foreseeable future. However, people in this society don't care about current affairs, so such a little life expectancy is nothing for young people, and won't smoking and drinking also reduce life expectancy?

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

"That was decades ago, I've heard of it...... You've launched a lot of probes, but it's not easy! ”

The girl with green eyes always speaks in such a flattering way: "It's a pity that I don't know the specific details, can you tell me about it?" ”

Zhang Yuan squinted his eyes and wrapped his cotton coat tightly, and he saw a snowflake floating down in the sky.

It's snowing.

Rare snowfall in the south.

He smiled, remembering that year they had launched a small sculpting robot to the moon.

The robot worked hard to carve a line of small letters into the huge stone tablet.

[Anpoch 1009212, June 13th, after a million years, we have gone through great efforts to return to the moon, what an exciting day! 】

[However, it is a pity that the world is not as beautiful as imagined, and human civilization is likely to permanently enter the trough of mediocrity......]

[The general trend of the times is vast, and the power of the individual is just a mantis arm as a car. 】

[A drug called "Sakura" is rapidly spreading in this world. It has drilled into the loopholes of the entire system, and our social system is powerless to stop it. All the people who oppose Sakura gather in Tokai City, but it is difficult to prevent ideological infiltration. 】

[We don't know if restarting the moon landing program at this time will make the whole world better, but it shouldn't make the world worse......]

[There is a high probability that we will not be able to stop the general trend of the whole world. If possible, we would like to establish another human kingdom on the moon, but it's difficult, really hard to ......]

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

[Disasters are always compassionate, it is like a lion on the grassland, reminding the sheep who blindly eat grass......]

Zhang Yuan looked at the distant horizon, told this period of the past, recalled the small victory in the past, and showed a faint smile.

He recalled an old song: "On a short and bright night, when the war is over, and the smoke has dissipated, where are you, comrades-in-arms?" Whenever the sun goes down and it is almost evening, I wander by the gate, and the breeze along the way may send my comrades here to meet me......"

It seems that it is spring again, that spring March, the age of cherry blossoms, when running on the cherry blossom avenue, a breeze blows, and the petals are scattered one after another, what a beautiful day......

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

The old man left this world forever......

Except for a few relatives and friends, who mourned for it, it did not cause any waves.

This world does not need heroes, and humanity will not perish because of it.

It's just that if you look at the cherry blossom world in a year, two years, a hundred years, a thousand years, ten thousand years, or a million years, you will find that human beings are still just the same human beings, and nothing has changed, and that's it.

Or, civilization is long dead, and there is not a single living cell left. All that's left is a swarm of bacteria, standing on the corpse of civilization and sucking the last nutrients, and that's it......

……

……

In the blink of an eye, Zhang Yuan returned to the small room full of blue points of light, and his brain was awake again, no longer like in old age, often wandering and distracted.

He was stunned, and seemed to be a little puzzled for a while, but he quickly couldn't help but recall the so-called "transcendental" assessment, as well as the former Kunlun Mountain fleet.

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

It's a complicated state of mind...... Tears couldn't help but gush out of his eyes, Zhang Yuan is not a person who likes to cry, but at this moment, he is still mourning for the "cherry blossom world" he has been in.

In fact, in the middle and late stages of the Sakura world, he has been worrying about his career and rarely recalls the past.

The virtual world is not a game, and the human beings in it are also living human beings, with their own emotions and thoughts. Time has passed, and there is no possibility of reading the file again.

Memories of all kinds are like marquees.

For his last life, although he had a hard time and was not satisfactory, Zhang Yuan felt quite satisfied.

The general trend of the times itself cannot be forcibly reversed by one or two people, and at the beginning, he knew that this matter was difficult.

As for the fact that after all the efforts, the final outcome has not changed in any way, that is another matter.

A voice seemed to come to mind: "Dear Mr. Zhang Yuan, you can rest here for a while, reminisce about the life you have experienced in the cherry blossom world, and when you are ready, you can start the next reincarnation." ”

A white point of light, sending a series of signals in his mind, is Pangu Brain's artificial intelligence "Sita".

Zhang Yuan slowly came back to his senses from the pain, and he said with a wry smile: "It's really painful, are you sure that the virtual world is to enjoy a good life?" ”

"You can choose pain, or you can choose happiness."

Zhang Yuan nodded, he had a physical presence in this small room, sitting on a chair and quietly reminiscing.

Leaving a familiar world, even if this world is extremely rotten, there is still a feeling of nostalgia.

But he really knows that it is difficult to get out of the quagmire by relying on his own strength when he has fallen into a mediocre civilization. In other words, unless there is a strong external interference, this "cherry blossom world" will continue like this forever.

It's a sad thing.

What is the source of sorrow?

Human civilization will not perish, and humanity will not perish because of it.

Nothing to be sad about.

Or perhaps, after he returns to the real world, he can try to interfere in the world of cherry blossoms, in fact, just a little interference, for example, the collapse of the robot system, the robot has no way to defend itself, and there is a mistake...... As long as the entire social system collapses, there will naturally be variables.

All in all, you have to pass the assessment of Pangu Brain's transcendental people......

Zhang Yuan didn't want to think about such complicated things for the time being, he just slept groggily to relieve the deep sadness.

(Sakura World ends!) ）
