Su Xia felt that she was getting stranger and stranger.

I don't know if it's because he has lived too long that he has become indifferent.

Long ago, he could no longer be touched by death.

He saw the demise of life, the destruction of civilization, the collapse of the universe, etc., but there was no fluctuation in his heart.

Like an emotionless observer, he stood coldly in the middle of time, witnessing the ups and downs of civilization.

Now he can create a life at will, or destroy a life at will.

He couldn't remember how many cosmic civilizations he had experienced.

The nature of the universe has been understood by him.

He felt as if he already had the ability to turn back time and space.

As long as he wants, he can go back to the years and let everything go back to the original way.

But, for some reason, he didn't want to do that.

Over the years, he seems to have lost not only his emotions, but also his memories.

Many years later, he was alone, drifting through the icy universe, silently pondering questions that he felt were important.

"Who am I?"

"Why am I obsessed with going back in time?"

"Am I the Creator?"

"If so, who created me?"

“……”

He pondered these questions for a long time.

In this way, he drifted through the universe for countless years.

He felt that perhaps it was because of the lack of affection that he had been unable to figure out these issues.

Before he knew it, he had drifted outside of a blue planet.

Su Xia looked at it silently, he felt that this planet was very familiar, as if he had been tied to this planet before.

But he was well aware that this planet was a product of the nascent universe and could not have anything to do with him.

"Let's go check it out."

Su Xia muttered to herself.

This planet has given birth to a civilization, a human civilization, which has not yet entered the interstellar age.

71% of the planet's surface is covered by seawater, and the other 29% is on land with more than 100 large and small countries.

Susha entered one of the countries, walked into one of the country's inland cities, paced slowly through the city, and rubbed shoulders with countless people.

He walked aimlessly around the city for a long time, like a wandering spirit who couldn't find a home.

The city was lively, but he couldn't empathize with it, all the laughter and laughter flowed away from him, and in the end all that was left was cold and lonely.

Su Xia was going to leave.

He wanted to find a quiet place and continue to think about those questions.

But, just before he was about to leave, a girl's laughter suddenly broke into his mind.

That laughter was familiar to him, as if he had heard it somewhere.

So, he turned to look back.

His gaze passed through the surging crowds, through the long streets, and finally in the distant square, he saw a bright girl smiling and smiling.

Beside the girl, there is also a boy with outstanding temperament.

The two are a couple, holding hands, talking and laughing, with sweet smiles on their faces.

The girl pointed to the movie poster in the square, smiled into a pair of crescent moons with big eyes, and said sweetly: "Su Xia, let's go see the Wandering Earth, the second part is out!" ”

"Good!"

Beside her, the boy named Su Xia agreed with a smile, his eyes full of tenderness.

The two held hands, their fingers clasped.

They walked into the cinema together and watched the sci-fi movie called The Wandering Earth.

After the film, they left the screening room and wrote a line on the message wall of the movie theater with a smile:

【Su Xia and Wang Xiaofan came here for a visit】

Behind this line of text is followed by a heart painted in red.

The two looked at the line with satisfaction, turned their heads to look at each other and smiled, and then walked out of the cinema together holding hands.

Su Xia stood in the distance, silently watching all this.

"Susha? What a familiar name......"

He slowly stepped back, sat down in a chair, and muttered under his breath.

At this moment, his heart was suddenly touched.

In the depths of my mind, it was as if something had been loosened by the dust for a long time.

"Why is it so familiar?"

"Where did I hear that?"

"Is it the return of people and things from the past before my eyes......

According to Poincaré regression, if the span of time is long enough, any particle will move to an area infinitely close to its initial position.

Although this span of time is far beyond the imagination of ordinary life, it is bound to come true.

A man dies.

Countless years later, a similar person will reappear.

A flower withers.

Countless years later, a similar flower will bloom.

It is said that many people will suddenly feel that someone, something, or something is familiar, as if they have met somewhere before, and it is because of this regression.

It's like reincarnation in some religions.

Whether it is a single life, or a planet, a civilization, or even an entire universe, it will reappear after a long time.

If a monkey is given enough time, it can also make a Hamlet.

The elementary particles that make up each person will reconstitute that person after a long time.

The two who fell in love in this life will finally be reunited in the next return of Poincaré.

In the history of philosophy, many people have made similar views.

For example, Nietzsche's eternal reincarnation.

Susha, a creature who has endured endless years, has witnessed a return and seen familiar people and things reappear.

"Susha...... My name seems to be Su Xia ......"

"Wang Xiaofan ......"

"Is that the girl who always sends me flowers?"

He pressed his head lightly, and more and more memories surfaced, gradually becoming clear from vagueness.

He remembered.

"This is the earth, it's Jincheng, it's the place where I lived......"

"I'm obsessed with going back in time and space in order to resurrect them, to recreate the ...... past"

Su Xia muttered to himself, everything in the past became clearer and clearer, flashing through his mind one by one.

Those who have passed, those familiar words, those unforgettable experiences, across a long river of time, returned to his mind again.

This time, he won't forget it again.

He slowly got up.

Looking at the couple who were drifting apart, a smile slowly appeared on his face.

Su Xia couldn't remember how long it had been since she had smiled.

Since the destruction of the Earth and the Blue Star, it was as if he had an extra cold mask on his face, and he had become a weirdo who would never laugh.

"I will raise you all."

Su Xia withdrew her gaze and returned to the starry sky, away from the planet.

After that, he silently stayed in an independent small space, observing the ups and downs of this cosmic civilization.

Ten billion years later, this time the cosmic civilization has come to an end.

All things return to darkness and silence.

Su Xia got up at this moment and took a step forward.

With his actions, the elementary particles that make up the entire world begin to move in reverse, and everything begins to flow backwards.

He is a lonely retrograde, with the determination of endless years, retrograde for hundreds of millions of years, step by step towards the world of memory.
