In the 500,000th year of prehistory, vertebrates became the overlords of the oceans, and species in the form of fish roamed freely in small puddles and multiplied wildly.

But compared to the fish on the earth, they are much smaller, and the largest adult is the size of a fry.

However, the frenzied reproduction of any species will inevitably be accompanied by a lack of living space.

In the 510,000th year, the petri dish species climbed the ladder again, along the glass wall of the petri dish, in an attempt to reach the sky.

Yang Shou mentioned the boiling water that had already been boiled, and he was extremely skilled in carrying out mass extinctions, becoming the mastermind behind the era.

In the 540,000th year, this era gave birth to more vertebrate species, and Yang Shou could even feel the messages and emotions they sent through their body language for interracial communication.

"Again?"

There was no need for a microscope, and Yang Shou could see creatures the size of small ants marching towards the glass wall.

Picking up boiling water, splashing it, turning into a black hand that covers the sky for eternity, the fourth mass extinction began.

"It's even heat-resistant!"

Life is really magical, Yang Shou found that after the extinction of the species four times, some creatures actually swam happily in the petri dish!

"You're having a great time!"

Yang Shou took a packet of salt from the kitchen and poured it into a petri dish.

The salt dissolved in the water, and the creatures that were jumping around kicked their legs and burped all at once.

"Gollum!

Yang Shou swallowed a mouthful of saliva, the fish soup in this petri dish is too fragrant, with salt, it must taste good, it would be better if it was sprinkled with some chicken essence or something.

These are all prehistoric fish, although they are only a little big, but they must be rich in nutrients!

In the end, Yang Shou still held back his appetite, these fish soups were used as food for the evolution of species in the next era, and he didn't want to waste his efforts.

"In prehistoric times, there was a fourth mass extinction of life, and the sea water became salty for unknown reasons, and from then on marine life was divided into freshwater and saltwater. ”

Yang Shou recorded in his notebook that this creation notebook, he planned to name it "Genesis", which was specially used to record major events such as species evolution and biological extinction.

Ten minutes later, 570,000 years before history, the fifth mass extinction began.

600,000 years ago, the sixth mass extinction began.

After six mass extinctions, species diversity has become richer, and small-body genes have been written into the body of new species.

At 610,000 years, all species are very small, and even the largest animals are no bigger than normal ants.

"Now I can rest assured, the petri dish can hold a hundred ants, and I need to survive the fittest and accelerate the birth of intelligent species. ”

Because of the uncontrollable nature of the species, Yang Shou was originally worried about the evolution of some terrifying species, but now that the body size is controlled, this worry is basically zero.

Unless they give birth to extraordinary powers, or technological civilization has developed to a certain extent, it is just a matter of pouring one basin of boiling water for him, and if not, then pouring two basins.

If you want to accelerate the birth of species, you need to find the genes of intelligent species.

The intelligent species on the earth, in addition to humans, are ancient species such as monkeys and dolphins.

"The remaining life is 89 days, 5 hours and 25 minutes, the current balance is insufficient, please recharge in time. ”

Looking at the time on the watch, Yang Shou gritted his teeth, chose to cut his finger, and dropped three drops of blood into the sea of petri dishes.

He didn't have that much time to work on monkey and dolphin blood, so he had to start the test directly with the blood that he had taken the cancer cells with.

Watch as the blood gradually melts, and as time accelerates, the fish in the ocean ...... at a rate visible to the naked eye Perish.

"it, my blood...... Is it so poisonous?"

The seventh mass extinction began, because of three drops of blood.

Yang Shou had a sentence in his heart, and scolded directly at the petri dish.

In 610,000 years of prehistory, the cycle of mass extinction, which occurs once every 30,000 years, was advanced.

By the time of 620,000 years of prehistory, after 10,000 years of recuperation, the species flourished again.

In the ocean, a new type of fish has successfully fused with Yang Shouyou cells, and the fins have begun to evolve into hands, legs, and tails, and they are trying to go to land.

"Finally it worked!"

Yang Shou was very excited, although the lifespan of this new species was only one second, which is equivalent to five years of petri dishes, it was already a great improvement.

"Noisy...... Noisy...... Noisy ......"

They made an unknown voice, probably hearing the sentence that Yang Shou said at the beginning of their birth, and accidentally remembered it in their genes.

They walked onto the land, and one by one, little ants and more than a hundred people lived together, and began to hunt for a living.

"You evolved from fish, so let's call them fish apes. ”

But the corresponding problem also came, more than a hundred fish apes developed wildly, and in a few minutes, even if they died extremely quickly, but as a species that gave birth to crude intelligence, they swept all land species in an instant, and occupied the entire land.

Because of the limitations of the genetic lock, the largest species in the petri dish is a shark-like fish that is the size of a small finger and still lives in the ocean.

Without natural predators, the entire land is densely packed with villains.

"I'm suffering from a phobia, it's time to find them a new home and create a world. ”

The previous petri dish was too small to support a race to develop a civilization.

The two main elements of reproduction and evolution of species are resources and space, both of which now limit their development.

Sure enough, it didn't take long for the original race of more than a hundred fish apes to start a fierce competition because of space and food, fighting, the number plummeted, and in the blink of an eye, only more than ten died.

In the next second, it continued to breed to hundreds, and then, the environment reached the upper limit of the race, and they fought again, sharply decreasing.

"Noisy ......"

They roared, holding homemade stone spears, fighting fiercely for resources, and Yang Shou was in pain when they watched. These are all intelligent species that have evolved with great difficulty by absorbing his blood cells, and he is reluctant to lose any of them.

"What should I do?"

Yang Shou frowned, and suddenly remembered that he still had a basement in his house, which was used to refrigerate vegetables. However, because both parents went out to work, it was abandoned.

Yang Shou hurriedly ran to the basement, fortunately, there were not a lot of debris piled up in the basement, and it took him an hour to clean up all the useless things.

The large basement of 80 square meters is enough for these species to evolve for a long time, anyway, their genetic locks limit the size, as long as the offspring of the species born in a petri dish will not grow to a large size.

In the basement, it is common to see darkness, no sun, but there are lights......

Yang Shou checked the tungsten light bulb and wiring, it can be used, this is the sun of the fish ape family in the future, although it is a little old, but it will be used, and it will be replaced by a new sun for you in the future.

I tested the fan of the exhaust outlet, well, the air is circulating, it will not suffocate, fix the first gear, and if the fish ape family is disobedient in the future, it will be turned on to the fifth gear......

In terms of water, Yang Shou smashed a big pit of four or five square meters in the middle of the basement, and regarded it as the ocean, the place where life originated.

When Yang Shou found the bottle and tweezers, and was about to grab the fish apes one by one, he found that they actually made a "whine" sound, like resistance and fear.

"They are killing each other, survival of the fittest from generation to generation, and in just an hour, they can already utter simple tone words, and they should not be far from simple communication. ”

As if taking care of children, Yang Shou put them in bottles one by one and took them to the basement.

"Go ahead, I hope you can surprise me. ”

Seeing more than a hundred fish apes crawling slowly on the ground, Yang Shou twisted the handle of the watch, adjusted the time speed, and after thinking carefully, he decided to reduce the time flow rate ratio to three hundred years a day, and the time flow rate of the petri dish remained unchanged, and continued to evolve species, and the high-quality species were selected and put in the basement.

Three hundred years a day, one hour is more than ten years, enough for him to observe the evolution of the fish ape civilization.

He still expects the fish and ape clan to take the transcendent route, and if he can develop the immortal system in Eastern mythology, he may really be able to solve the cancer in his body.

Thinking of the legendary sword qi spanning 100,000 miles, and the various magical powers between the sky and the earth, maybe it may really be realized from the time turner in the future?

The evolution of civilization is diverse, and the legendary gods may not be impossible to achieve through the evolution of species, after all, there are always one or two species that have evolved over hundreds of millions of years with incredible abilities.

Taking a deep breath, Yang Shou silently looked at these fish apes, full of anticipation.

Now his time is three times as consumed, and if he wants to maintain the flow of time in the petri dish and the basement, he must continue to consume life, leaving him with little time.

At this time, in the petri dish, after the disappearance of the fish ape family, after 200,000 years of evolution, a new species of giant beasts evolved on land.

Their bodies are covered with a thick layer of scales, and their teeth are sharp, but they are slow-moving, four centimeters tall, but they are extremely difficult to reproduce, and they only number a few dozen in 200,000 years.

"A race without natural predators is a race without hope, and it's time to bring a crisis to the fish ape race. ”

Yang Shou also threw these giant beasts into the basement, which was only four centimeters to him, but to the fish ape, it was like a giant beast of more than ten meters, an absolute world hegemon.

Not only the giant beast, but also the other animals and plants that bred in the petri dish, he also put them into the basement, otherwise with the flow rate of the basement, animals and plants need to be reborn, and before that, the giant beast and the fish ape will have to starve to death.

"Starving, eat. ”

Stretching, Yang Shou walked out of the basement and prepared to go downstairs to eat a bowl of noodles.

He has made all the preparations that should be made, and the next thing is to see the development of the fish ape clan itself.

"Xiao Yang, what's the matter with your hair, why did you become bald?"

The proprietress of the noodle restaurant grew up watching Yang Shou since she was a child, looking at Yang Shou's miserable white face and bald head shaved due to chemotherapy, she probably guessed something.

"It's okay, I just like bald heads all of a sudden. ”

Yang Shou smiled kindly, and let out a little panic, he didn't dare to tell the truth, you know, only his ex-girlfriend knew about his illness, and he didn't even tell his parents.

If the proprietress knows, it's no different from the whole community knowing.

The proprietress sighed, but her tone was still full of regret and regret, and she brought Yang Shou a bowl of beef noodles quite sympathetically, "It's rare for you to come back after graduating from work, I won't charge you money for this noodle, so I have a good taste of my childhood." ”

"Good. ”

Yang Shou was not hypocritical, "Aunt Zhao, your shop is still old-fashioned, and you can't eat it if you want to eat it outside." ”

"Is that okay, my mother's noodles are still bad?"

A crisp voice came, and Yang Shou followed the voice to look over, it was the daughter of the proprietress who was now studying biological sciences at Yenching University.
