In a university biology laboratory, Yuan Chu was busy sitting in front of the computer.

The light and shadow on the monitor naturally spilled onto the lenses of his glasses, and flickered with the sound of keyboard tapping.

In addition to being busy, Yuan Chu felt a trace of fatigue in his heart.

He once dreamed of becoming a scientist, but when he really got in touch with the field of scientific research, he realized that this work was also boring and repetitive.

Looking at the work summary that was about to be written in front of him, he seemed to have seen the end of his entire scientific research career.

Just as he was feeling a little lost in his heart, a voice diverted his attention.

"Senior brother, do you believe that there is reincarnation in this world?"

The person who spoke was a girl in a white lab coat, and she was leaning against the incubator at this time, looking a little lonely.

Others are expected to be full of question marks when they hear this question, but Yuan Chu knew that the cat in her sister's house went to the cat not long ago, and she has always been difficult to let go of it.

After a moment's silence, he replied earnestly:

"Well, the order in which energy, matter, and information are arranged is finite, no matter how small the probability is, after an infinite number of exhaustive actions, there will definitely be one time that is closest to the initial position, which should be regarded as reincarnation in a sense.

Since there is a Poincaré conjecture to support this view, I choose to believe it. ”

"Poof!"

Hearing Yuan Chu's thoughtful answer, the senior sister was amused by him.

"Haha, it's really hard for you to come up with such a reason, junior brother, I thought you would say you don't believe it."

Yuan Chu shrugged his shoulders helplessly when he heard this, it is not false that he is a standard straight man in science and engineering, but he still has basic emotional intelligence.

"Okay, count you as if you pass the test, it's not in vain, senior sister, that I'm busy with your affairs.

Here, this is something you asked me to borrow for you. ”

As she spoke, Senior Sister took out a petri dish from the incubator next to her, and she handed it to Yuan Chu and did not forget to advise:

"Although I borrowed something for you, others are only allowed to borrow it for one day, and I need to return it tomorrow.

After all, this is a fungus recently discovered by the scientific expedition team in the polar ice, and it is said to be able to push the formation age of eukaryotes back hundreds of millions of years, which is very valuable for research. ”

"Well, I understand, I borrowed this thing just to water two papers.

Don't worry, I'm in the lab all night today, and I won't delay tomorrow. ”

"And what I said before, when this thing is done, you have to invite me to dinner, don't try to fool me with the school cafeteria, you have to invite me to a big meal."

Under Yuan Chu's assurance, the senior sister left satisfied, and he was the only one left in the huge laboratory for a while, looking at the petri dish in his hand, the original confusion was dispelled a lot.

"If I can publish two valuable papers, maybe my work will take a turn for the better."

Yuan Chu finished summarizing the work as quickly as possible, and then prepared to observe the borrowed fungal samples.

When everything was ready, he brought his eyes to the biomicroscope to get a glimpse of the primitive microbes of eons ago.

However, the moment he saw the fungal entity through the glassware, something strange erupted.

Everything around him disappeared in front of Yuan Chu's eyes one after another, and the only thing he could see was the fungus except for himself.

didn't have time to delve into the reason, and the next moment his feet were empty, and the whole person fell towards the bottomless void.

Time and space lost their meaning in the endless void, and Yuan Chu felt that he was caught in a cycle with no end in sight.

Just blinked, and when he opened his eyes, he found that he was on the verge of death, and after a moment of astonishment, he had become a baby in swaddling clothes.

There is no life experience, only life and death in the void with no end in sight.

Recovering from his initial uneasiness, Yuan Chu forced himself to calm down and began to look for the reason.

Looking at the fungal samples in the void that were also undergoing the cycle of life and death, he felt that he might be caught in the midst of a partial Poincaré return.

Normally, a deck of cards will be shuffled more and more chaotic, but as long as you keep shuffling, there is a chance that the order of the cards will be shuffled to the original state.

And Poincaré regression roughly means that when all the elementary particles in the universe move to their starting position, then everything will reset.

No one knows how long it will take to complete a round of returns, though.

After all, that's a lot of cards, but what if there's only two cards in the deck.

Yuan Chu and the fungus were such an isolated combination that unexpectedly constituted a return to Poincaré involving only the two.

The reset switch was pressed the moment he observed the fungal sample, but could never be stopped.

Getting such an answer, Yuan Chu couldn't help but feel a little desperate.

Poincaré's regression is difficult to break, and even if he and the fungus are isolated from the physical world due to an accident, the small partial regressions are still repeated among them.

However, in the endless cycle of life and death, he still found a glimmer of opportunity.

If the essence of regression is a law of material circulation, then the amount of matter must determine the strength of the cycle.

The fact that he is now able to retain consciousness while repeating between life and death shows that only he and the fungus are involved in the small return, which is not perfect because the material basis is too poor.

So, he seized the node of life and death, and tried to inject his consciousness into the fungal samples on the side again and again, in a vain attempt to break the current fragile cycle with position changes.

…………

The next day, when the senior sister came to the laboratory, she suddenly heard the bad news that Yuan Chu died suddenly in the laboratory due to overwork.

"Obviously, there were still jokes yesterday, but if I hadn't stayed up all night studying fungal samples, this tragedy wouldn't have happened."

The senior sister who fell into self-blame sincerely prayed that the so-called reincarnation was indeed a thing, and she hoped that whether it was a dead cat or Yuan Chu, they could reappear at some point in the future.

It's a pity that my sister's wish is destined to fail.

The partial return of Poincaré was finally broken by Yuan Chu, and only his body was reaccepted by the world.

His consciousness was exiled, and this was the price to pay for breaking the cycle.

At the moment, he is shuttling through the corridor of light formed by the inverse Doppler effect, and even time cannot catch up with him.

Cenozoic, Jurassic, Cambrian, Proterozoic, Medieval, Archean......

He is like a fish swimming back, swimming upstreams along the path of light.

When Yuan Chu came back to his senses, he was already in a scorching heat, looking at the back of his round body, dragging a constantly swinging flagella, he was a little speechless for a while.

That's right, the polar fungus, as a carrier of consciousness, also followed him here, to the earth 4.57 billion years ago.

He tried to break his consciousness out of the fungal shell, but the next moment, everything around him came to a complete standstill.

No, it's not static but eternal.

As a detached man who broke Poincaré's return, the place of his consciousness is eternal.

Even if one day the universe is restarted due to his return, he will remain in place forever......
