In the 59th year of the appearance of "Cherry Blossom", Zhang Yuan, with white hair, came to Atia Park in the north of Donghai city

The celebrity behind the "Atia Park" is Sir Atia, a mathematician in the 20th century. This mathematician is famous for proving the "index theorem", but now people rarely investigate this aspect, let alone know what the so-called "index quantification" is and what its use is

Zhang Yuan, leaning on a crutch, sat down on a stool.

Years of worry and great mental pressure have taken away his health, so that he can't fight the whole world with ambition like when he was young

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

In March, when cherry blossoms are in full bloom, every cherry tree in the park is covered with flower fairies, large and small. Some have just stood firm, some have inserted themselves into the branches, and some are still bright, but they are weak.

A breeze blew, and the petals fell on his palm and on the ground.

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

Every year in the past, comrades in arms from all over the world came to "Atia Park" to discuss the form of today's world. They discussed how to stop the proliferation of "cherry blossoms", how to land on the moon, how to improve existing rockets and other topics.

At least, 30 years ago, 40 years ago, and 50 years ago.

Especially in the period when the rover just landed on the moon, many people with ideals were passionate 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 establish our own country!"

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

I can still recall the ambition of my youth.

However, fifty-nine years have passed, and they have not been able to do this after all. Aerospace engineering needs too many talents. They do not have time to win.

These people are gone, disappeared, do not know where to go.

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

At night, it is time for all kinds of men and women to come and go looking for prey. A young girl, who found Zhang Yuan in a suit and shoes and sitting upright, was involuntarily eager to try.

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

"You won't have a sudden myocardial infarction or stroke? In that kind of thing... It seems good to go to paradise! "

With this little devil like mind, she stood on tiptoe and quietly walked past, involuntarily thinking of all kinds of strange scenes in her mind.

Compared with physical happiness, psychological happiness is better.

She hasn't played such an interesting thing yet!

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

Of course she knows the famous anti Cherry Blossom person. She will never doubt that when she tries to invite, Zhang Yuan will wave a crutch and smash her head - just like hammering a crisp watermelon.

Even if she eventually changed her life, it must not be worth it if she was so young.

"How could anyone object to cherry blossoms? be rather baffling! Our world... Isn't it beautiful? " The girl thought angrily and left in a hurry.

At twelve o'clock in the evening, a cleaning robot passed by and found Zhang Yuan still waiting in his seat.

The green eyed girl said, "Sir, due to your health considerations, you should go home... Sitting here will catch a cold, which is not conducive to your health."

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

"OK, no problem. Please put on this hat for your health. " The girl took off her hat and helped Zhang Yuan put it on.

In fact, she does not have her own emotions, but naturally maintains the "absolute justice" regulated by human beings.

Zhang Yuan waited until early in the morning and finally didn't wait for a comrade in arms.

Seeing the first ray of sunshine coming out of the eastern sky, it was warm on my face.

"Chaoyang is so nice." Zhang Yuan said.

"Yes, the sun always rises in the East... Such days can last for five billion years." The robot girl held her face in one hand and whispered.

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

"Five billion years later, the sun exploded and mankind perished."

Zhang Yuan said: "compared with the huge figure of 5 billion years, people's life, 100 years, is too short. It's too short to do anything."

"Five billion years, how long it is. If it keeps going back and forth like now, it will never change. It's too bad."

Zhang Yuan finished his last sentence and left with a crutch.

The robot girl owes her body and shows her due respect to an old man: "you go well."

Zhang Yuan waved behind his back. No one knew his final mood.

……

Zhang Yuan, who was not in good health, struggled through the winter of the year.

The spitting and exclusion of others does not affect the care of the robot system.

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

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

The robot girl's name is "Ling". She has always been lively and cheerful. She can often chat with him, although she is dull and can't answer some complex contents.

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

Since the spread of cherry blossoms, the average life expectancy in the world has decreased by 2.6 years, which should continue to decline in the foreseeable future. However, people in this society do not care about current politics. Such a little life expectancy is nothing for young people. Won't smoking and drinking also reduce life expectancy?

"Do you know what words were engraved on that stone tablet by our original Lunar Rover?" Zhang Yuan asked Ling behind him.

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

The girl with green pupils always likes her way of speaking: "unfortunately, 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 snowflake floating down in the sky.

It's snowing.

Snow is rare in the south.

He smiled and recalled that year, they launched a small carving robot onto the moon.

The robot worked hard to carve a line of small characters in that huge stone tablet.

[on June 13, 1009212, after a million years, we tried our best to return to the moon. It was an exciting day!]

[however, unfortunately, the world is not as beautiful as expected. Human civilization is likely to permanently enter the trough of mediocrity...]

[the general trend of the times is vast, and individual strength is only a mantis arm in the cart.]

[a drug called "Cherry Blossom" is spreading rapidly in the world. It has drilled the loopholes of the whole system, and our social system is unable to stop it. All those who opposed cherry blossoms gathered in Donghai City, but it was 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 should not make the world worse...]

[we probably can't stop the general trend of the whole world. If possible, we want to build another human country on the moon, but it's difficult, really difficult...]

[if human beings can 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?]

[disaster is always compassionate. It is like a lion on the grassland, reminding sheep who are always eating grass...]

Zhang Yuan looked to the distant horizon and told the past. He recalled his little victory and showed a faint smile.

He recalled an old song: "on a bright and short night, the war is over and the smoke of gunpowder has dissipated. My comrades in arms of the same regiment, where are you now. Whenever the sun sets, I wander around the gate near the evening. The breeze along the way may send my comrades in arms here to meet me... "

It seems that it is spring again. In March, when the cherry blossoms are in full bloom, when running on the Cherry Avenue, a breeze blows, and the petals fall in succession. What a beautiful day

Ling suddenly found that Zhang Yuan in the wheelchair seemed to be asleep, but this time it was a real permanent sleep, and there was no possibility of waking up.

The old man left the world forever

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

The world does not need heroes, and mankind will not perish.

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

Or, civilization has long been dead and there is no living cell. The rest is just a group of bacteria, standing on the corpse of civilization and absorbing the last nutrition, that's all

……

……

In the twinkling of an eye, Zhang Yuan returned to the small room full of blue light spots. His brain regained consciousness. He was no longer distracted and distracted as in old age.

He was stunned. It seemed that he couldn't figure out the situation for a moment and a half, but soon he couldn't help recalling the so-called "extraordinary" assessment and the once Kunlun Mountain fleet.

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

This mood is very complicated... Tears can't help pouring 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 stayed in.

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

In fact, there is not much difference between the virtual world and the real world. The virtual world is not a game. The human beings inside are also living human beings, with their own emotions and thoughts. As time goes by, there is no possibility of reading files again.

All kinds of memories are like walking a lantern.

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 can not be forcibly reversed by one or two people. At the beginning, he knew it was difficult.

As for the effort, the final outcome has not changed, that is another matter.

It seems that a voice came to mind: "Dear Mr. Zhang Yuan, you can rest here for a while and recall your whole life in the cherry world. When you are ready, you can start the next reincarnation."

A white light spot sent a series of signals in his mind. It was Pangu's artificial intelligence "West Tower".

Zhang Yuan slowly recovered from the pain. He smiled bitterly and said, "it's really painful. Are you sure that the virtual world is to enjoy a better life?"

"You can choose pain or happiness."

Zhang Yuan nodded. He had an entity in this small room and sat in his chair quietly remembering.

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

But he really knew that it was difficult to get out of the quagmire with his own strength when he fell into a mediocre civilization. In other words, unless there is strong external interference, the "Cherry Blossom world" will continue like this.

What a sad thing.

What is the source of sorrow?

Human civilization will not perish, and mankind will not perish.

There's nothing to be sad about.

Or maybe, after he returns to the real world, he can try to intervene in the cherry blossom world. In fact, just a little intervention. For example, with the collapse of the robot system, robots can't protect themselves and make mistakes... As long as the whole social system collapses, variables will naturally occur.

In a word, we should pass the examination of Pangu's extraordinary

Zhang Yuan didn't want to think about such a complicated thing for the time being. He just slept a long sleep to ease the deep sadness.

(Sakura world is over!)
