"Plankton in the sea has appeared...... The mother nest has begun to set up genetic locks to limit the size of spore organisms!"

Xu Shi frowned and silently gave instructions.

The orchards are so big that it is impossible for them to evolve too big.

In the memories of the previous generation of Mother Emperors, it also showed that the way the huge body evolved was wrong.

There is no need to deliberately expand the size of the Zerg, maintaining the small size of the original Zerg is the correct way to evolve, the smaller the size, the easier it is to give birth to the qualitative change of energy.

They no longer expand in size.

Since then, the size of the normal species in the sand table is smaller than that of ordinary ants, which is the real bug, the Zerg. And the largest species, even if it evolves to the level of a dinosaur, will not be bigger than a cat.

A worm, the size of a cat, is already an exaggeration, and a hundred acres of sand table is equivalent to the size of a small province for a miniature ecological creature with the size of a small ant.

On the afternoon of the sixth day, the Paleozoic ocean, which had experienced the previous five days, finally changed dramatically, and multicellular organisms began to appear in the seawater.

In a matter of minutes, Xu Paper is like an accelerated piece of ecological discipline, and on the artificial ocean of this pond, new plankton species are constantly born in a matter of seconds, and then die, giving birth to the next generation...

Soon, in the pond in the orchard, patches of all kinds of exotic aquatic plants floated.

Xu Zhi originally wanted to give it a try and cast a single cell to evolve species in the ocean, but he didn't expect it to be so fierce.

"10,000 years accelerated into one day, only six days, 60,000 years of species evolution, the single-celled organisms in the ocean, evolved into plankton in the sea, forming a super Paleozoic ocean similar to the end of the earth's 'Phanerozoic', 500 million years ago in the Cambrian explosion, this zerg spores are so powerful that they explo.......de."

Xu Zhi does not understand these evolutionary histories of the earth.

But he can naturally go back to his room, open his laptop, search on the Internet, and make up for the evolutionary history of the earth, the birth and origin of species, the Cambrian, Silurian period, Devonian...

After all, the earth can be used as a reference.

"But it's getting dark soon, and my biggest fear begins, the world of the sand table is going to be destroyed..."

He looked at the man-made ocean in the courtyard and looked up at the gloomy sky, where dusk cast the last afterglow in the corner of the wall.

The evolution of cell division is accelerated by 10,000 times, and he condenses and accelerates 10,000 years into one day, which is equivalent to 5,000 years being day and 5,000 years of night.

Now that it's dark, it's equivalent to the long 5,000-year-long day has passed, and the 5,000-year-long endless night is about to usher.

Sunlight is the source of all things, and these aquatic plants that have just been born in the ocean will lose their photosynthesis and will die directly.

Sure enough, just after nightfall, the moment the sun was lost, there was a drastic change in the sea.

Large swaths of aquatic plants withered, sank to the bottom of the sea, and lost their lives, like the Dead Sea, lifeless in the night.

"In my evolutionary era, the first mass extinction began... Didn't expect it to be so fast. ”

Xu Zhi took a deep breath.

He looked up the information on the Internet.

In the long era of evolution, the earth has experienced five tragic mass extinctions from the birth of single cells, multicellular evolution, and the reproduction of various Paleozoic species!

Historically, the most famous natural is the mass extinction at the end of the Cretaceous period, 65 million years ago, the destruction of the earth's former overlord, the age of dinosaurs, when 80% of animals died.

And the first mass extinction on Earth was actually a mass extinction at the end of the Ordovician period more than 400 million years ago.

That's because the temperature plummeted and the sea level dropped, which led to the destruction of the earth's marine ecosystem, directly extincting 85% of marine species at that time.

Now, unlike the Earth Era, this sand table under his command is because night came, and suddenly the endless darkness of five thousand years fell, and the sun suddenly disappeared, causing his first mass extinction.

The earth is a huge planet, in which billions of species, the survival of the fittest, has huge compatibility, even if the mass extinction of organisms can survive.

And he is different here, the environment is too small.

Logically speaking, even if the ponds and oceans are filled, there are only tens of millions of races, and according to Darwin's theory of evolution, a very small number of organisms is not enough to evolve a new organism that adapts to the environment.

"But this is an extremely adaptable Zerg single cell, a spor, that can survive on a barren planet, and there's no reason why it can't be here..."

Xu Zhi took a deep breath, inevitably a little excited and uneasy.

He waited silently, and the moonlight poured down from the courtyard, and the sea of lifeless, plant corpses passed, and after half an hour, suddenly another faint blue came to the surface.

It was a blue plant the size of an ant with delicate shapes of leaves.

Losing direct sunlight from the sun, the plant chose to point the source of photosynthesis at the moon, which had extremely little light, and survived.

After successfully surviving the first round of mass extinction, the plant grows, develops, and dies in a matter of seconds, like an accelerated movie video.

It began to evolve rapidly from generation to generation, natural selection, and frantically adapted to the night environment, and water chestnuts and discs appeared, like lotus leaves tiled on the sea surface, in order to be able to absorb the moonlight in the courtyard sky on a large scale.

Another hour passed.

As the only marine species in the sand table, the aquatic plant named "Blue Moon Grass" by Xu Paper has undergone tens of thousands of generations of species evolution and began to form various branches.

There are angular, elongated, oval, deep-sea, shallow-sea..... At this time, it even developed two divergent species.

A part of the Blue Moon Grass continues to absorb moonlight in its evolution, enhancing the transformation efficiency of moonlight.

Some of the Blue Moon Grass actually began to turn to carnivorous, preying on other Blue Moon Grasses, and they also absorbed the moonlight, so as to attract other Blue Moon Grasses to float over and then swallow them.

Seeing this, Xu Zhi admired the tenacity and wonder of life, the survival of the fittest, "survived the first mass extinction of life, the only living aquatic plant, and developed its own diverse civilization in the dark night ocean." ”

He took out a black notebook, picked up a pen, and recorded the evolution of this sand table.

"Or, according to the epochal calendar of the earth, record the countless epochs of the evolution of my sand table?

In the Cambrian period on the earth, there was a biological explosion, which was the origin era of all life on earth, and there were dinosaurs, humans, and all kinds of beasts..... And the biological explosion here is facing five thousand years of darkness.... Let's call it Dark Takeki. ”

He was so excited that in this black notebook, he turned the first page of the founding century and wrote the first row on it:

[Dark Martial Era, the heavens and the earth changed suddenly, the sun set and the moon rose, the world fell into a long darkness of five thousand years, 99% of the marine life was extinct, only the Blue Moon Grass absorbed the moonlight to survive, becoming the only surviving species, extremely prosperous in this dark ocean, Blue Moon Grass, became the overlord of the era]

He looked at the pond called the Ocean of Life, silently expecting,

"According to the history of biological evolution on the earth, the ocean is the origin of all life, and marine plants appear first, and then continue to reproduce, that is, marine animals, Zerg cells, what marine animals will evolve....."

He didn't sleep all night until dawn.

Day 7 has finally begun!

However, instead of starting to evolve animals on the seventh day, as Xu Shi thought, another terrifying mass extinction was ushered in!

Because the sun rises.

As the sun rises, all kinds of blue moon grasses in the sea that flourish in the middle of the night quickly wither.

They had received the weak moonlight at night, but now they suddenly received such strong direct sunlight that they sank to the bottom of the sea as if they had been burned.

In an instant, the Blue Moon Grass began to be extinct on a large scale again.

"The second mass extinction, which broke out so soon, and it didn't take long to survive, it was simply miserable...."

This is the death of life.

In the long evolutionary era of species, in hundreds of millions of years, countless species were born and extinct, which was a vast planetary epic.

The process of spore evolution and life is long and rotten, but at this time, in just a few hours, countless prosperity and rise and fall are displayed in front of him, and the shock brought to Xu Paper is powerful and inexplicable.

By the afternoon, a splash of blue was gradually coming back to life from the dead plants.

It was a five-star shaped Blue Moon Grass, which also ushered in its own mutation and evolution, successfully escaping this mass extinction, transforming in the scorching sun, and being reborn from the fire.

In order to be more accustomed to the intense sunlight, it began to reproduce from generation to generation.

In just a few minutes, it died, was reborn, and multiplied for countless generations, and began to gradually change from blue to dark, and gradually to purple and black... Eventually, a mystical black-blue pentagram seaweed was formed.

It has a five-pointed star with beautiful mystical balanced leaves, which can expand and open.

At night, the five corners are spread flat on the surface of the sea to increase the area that absorbs moonlight, and during the day, in order to prevent strong sunlight, it shrinks by more than half and becomes a flower bone.

A bit of a mimosa pattern.

The mass extinction of species is an extinction, but also an opportunity for the rise of weak and small species.

In the whole ocean, no species compete with it for the living environment, and it begins to multiply rapidly, multiplying all kinds of side branches, and the whole ocean is full of vitality.

"Survive 5,000 years of scorching sun and 5,000 years of dark night. ”

"Five thousand years of the sun and the moon in the sky, as the only living person of countless species, you have experienced the scorching sun and darkness, you are the real hero, just call it Purple Grass. Xu Paper laughed, silently picked up the pen, and turned the second page of the black diary.

Continue to record the second mass extinction event in the evolutionary history of his biological epoch:

[In the Guangwu Period, the heavens and the earth changed suddenly, the moon set and the sun rose, and the scorching sun hung in the sky for 5,000 years, and the overlord of the Blue Moon Grass, who had survived the Dark Martial Era, began to extinct a wide range of species, among which the purple grass in the weak vein of the Blue Moon Grass actually rose into the sky and became the protagonist of the era that dominated the era]
