"Planktonic organisms in the sea have emerged... Mother nests have begun to set up gene locks to limit the size of spore organisms!"

　　Xu Zhi frowned and silently gave instructions.

　　The orchard is just so big, it's impossible for them to evolve too big.

　　In the memory of the previous mother emperor, it was also shown that the evolution of the huge body was incorrect.

　　There is no need to deliberately expand the size of the insect race. Maintaining the original small size of the insect is the correct way of evolution. The smaller the size, the easier it is to produce a qualitative change in energy.

　　They no longer expand in size.

　　From then on, the normal size of sand table species is slightly smaller than that of ordinary ants, which is the true insect, the Zerg tribe. And the largest species, even if evolved to the level of dinosaurs, would not be larger than a cat.

　　A worm, the size of a cat, is already an exaggeration, and a sand table of 100 acres is equivalent to a small province for a tiny ecological organism with the size of a small ant.

　　On the afternoon of the sixth day, after experiencing the single-cell Paleozoic ocean of the previous five days, there was finally a dramatic change, and multicellular organisms began to appear in the seawater.

　　In just a few minutes, Xu Zhi felt like an accelerating ecological discipline film. In the artificial ocean of this pond, new planktonic species kept emerging and disappearing in just a few seconds, giving birth to the next generation

　　Quickly, in the pond of the orchard, various peculiar aquatic plants floated.

　　Xu Zhi originally wanted to give it a try, throwing single cells into the ocean to evolve species, but he didn't expect it to be so fierce,

　　"Ten thousand years have accelerated into one day, and this is only six days. The species evolution that lasted for sixty thousand years has evolved from single celled organisms in the ocean to planktonic organisms in the sea, forming a super Paleozoic ocean similar to the end of the Phanerozoic era and the Cambrian explosion five hundred million years ago. This insect spore is incredibly powerful..."

　　Xu Zhi doesn't understand the history of Earth's evolution.

　　But he could naturally go back to his room, open his laptop, search the internet, and frantically study the evolution history of the Earth, the origins of species, the Cambrian, Silurian, and Devonian periods

　　After all, the Earth can serve as a reference.

　　"But the sky has turned dark, and my biggest concern has begun. The world of the sandbox is about to be destroyed..."

　　He looked at the artificial ocean in the yard, looked up at the gloomy sky, and the last afterglow fell in the corner of the wall at dusk.

　　The evolution of cell division accelerates ten thousand times, and he condenses ten thousand years into one day, which is equivalent to five thousand years of daytime and five thousand years of nighttime.

　　Now it is dark, which is equivalent to the long five thousand years of daylight having passed and about to usher in an endless five thousand year long night.

　　Sunshine is the source of all things, and these newly born aquatic plants in the ocean will lose their photosynthesis and die directly.

　　As expected, just as night fell and the sunlight was lost, there was a drastic change in the seawater.

　　Large areas of aquatic plants wither, sink to the bottom of the sea, lose their life, like a dead sea, lifeless under the night.

　　"In my evolutionary era, the first mass extinction of organisms began... I didn't expect it to happen so quickly."

　　Xu Zhi took a deep breath.

　　He has searched for information online.

　　In the long era of evolution, the Earth has gone through five devastating mass extinctions, including the birth of single cells, the evolution of multicellular organisms, and the proliferation of various Paleozoic species!

　　In history, the most famous natural event was the mass extinction of organisms at the end of the Cretaceous period. 65 million years ago, the Earth's former hegemon, the destruction of the dinosaur era, resulted in the death of 80% of animals.

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

　　That was because of the sudden drop in temperature and sea level, which led to the destruction of the Earth's marine ecosystem and directly wiped out 85 marine species at that time.

　　Now, unlike the Earth Age, the sand table under his command suddenly fell due to the arrival of night, which lasted for five thousand years of endless darkness. The sun suddenly disappeared, causing his first species extinction.

　　The Earth is a huge planet, with billions of species, undergoing survival and selection, and has great compatibility, even if it can survive a mass extinction.

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

　　In theory, even if a pond is filled with oceans, there are only tens of millions of species. According to Dall's theory of evolution, a very small biological population is not enough to evolve a new organism that can adapt to its environment.

　　"But this is a highly adaptable single celled spore of the Zerg race, which can survive on a barren planet. There is no reason not to..."

　　Xu Zhi took a deep breath, feeling somewhat excited and uneasy.

　　He waited quietly as the moonlight fell from the yard, creating a lifeless ocean full of plant corpses. After half an hour, a faint blue light suddenly surfaced on the surface of the water.

　　That is a blue plant the size of an ant with exquisitely shaped leaves.

　　Losing direct sunlight from the sun, this plant chose to focus its photosynthesis source on the extremely dim light of the moon, allowing it to barely survive.

　　This plant successfully survived the first round of species extinction, growing, developing, and dying in just a few seconds, like an accelerated movie recording.

　　It began to evolve rapidly from generation to generation, competing for natural selection, and adapting frantically to the dark night environment. It appeared with water chestnuts, discs, and lotus leaves laid flat on the sea surface, in order to better absorb moonlight from the courtyard sky on a large scale.

　　Another hour has passed.

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

　　Some have long edges, some are slender, some are elliptical, some are deep-sea, some are shallow At this point, it even developed two differentiated species.

　　Part of the blue moongrass continues to absorb moonlight during evolution, enhancing its conversion efficiency.

　　A portion of the blue moongrass actually began to carnivore, preying on other blue moongrass. They also absorbed moonlight, emitting a faint fluorescence to attract other blue moongrass to float and then swallow it.

　　Xu Zhi saw this and praised the tenacity and wonder of life, survival and survival. "Having survived the first extinction of life, this only surviving aquatic plant surprisingly developed its own diversity in the dark ocean."

　　He found a black notebook, picked up a pen, and recorded the evolution process of this sandbox,

　　How about recording the countless epochs of my sandbox evolution according to the Earth's epoch calendar?

　　The Cambrian period on Earth witnessed the Big Bang of life, which marked the origin of all life on Earth, with dinosaurs, humans, and various fierce beasts And the creatures here have exploded, yet they face five thousand years of darkness Let's call it "Dark Martial Chronicles"

　　He was full of enthusiasm and flipped through the first page of the founding century on this black notebook, writing the first line of words on it:

　　During the Dark Wuji period, the heavens and earth suddenly changed, the sun and moon rose, and the world fell into a long darkness that lasted for five thousand years. The 99 marine creatures went extinct, leaving only the Blue Moon Grass to absorb moonlight and survive, becoming the only species that survived. In this dark ocean, the Blue Moon Grass thrived extremely, becoming the hegemon of that era

　　He looked at the pond called the Ocean of Life, silently anticipating it,

　　"According to the history of Earth's biological evolution, the ocean is the origin of all life. Marine plants emerged first and continued to reproduce, which are marine animals, insect cells, and what kind of marine animals will evolve..."

　　He stayed up all night until dawn.

　　The seventh day has finally begun!

　　However, it was not as paper had imagined that animals began to evolve on the seventh day, but rather that another terrifying mass extinction occurred!

　　Because the sun rises.

　　At the moment of sunrise, various blue moongrass in the bustling ocean at night quickly withered.

　　They used to receive weak moonlight at night, but now they suddenly receive such strong sunlight, as if burned, and sink into the sea.

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

　　"The second mass extinction of organisms broke out so quickly, and they just survived for a short time. It was truly devastating..."

　　This is the demise of life.

　　In the long evolutionary era of species, countless species have emerged and become extinct over billions of years, which is a vast planetary epic.

　　The process of spore evolution and life is long and decaying, but in just a few hours, it presents countless prosperity and decline before our eyes, bringing a powerful and inexplicable shock to Xu Zhi.

　　In the afternoon, a touch of blue gradually regained vitality from the dead plants.

　　That is a five star shaped blue moongrass, which has also undergone its own mutation and evolution, successfully escaping this mass extinction, transforming in the scorching sun, and reborn from the ashes.

　　In order to better adapt to the strong sunlight environment, it has started to reproduce for generations.

　　In just a few minutes, countless generations passed away, reborn, and multiplied, gradually turning from blue to dark and purple black In the end, a mysterious black and blue five pointed star seaweed was formed.

　　It has beautiful, mysterious, and balanced pentagonal leaves that can stretch and unfold.

　　At night, open the five corners and flatten them on the sea surface, increasing the area for absorbing moonlight. During the day, to prevent strong sunlight, they shrink by more than half and become flower like flowers.

　　A bit of a mimosa like pattern.

　　The mass extinction of species is both extinction and an opportunity for the rise of vulnerable species.

　　In the entire ocean, there is no species competing with it for a living environment, and it has started to rapidly reproduce, giving rise to various branches and thriving throughout the entire ocean.

　　"Survive five thousand years of scorching sun and five thousand years of darkness."

　　"Five thousand years of sun and moon in the sky, as the only one of countless species, experiencing the scorching sun and darkness, you are the true hero, just call yourself Zizhao Grass." Xu Zhi laughed and silently picked up his pen, turning to the second page of his black diary.

　　Continue to record the second major extinction event that occurred in his biological epoch evolution history:

　　During the Guangwu period, there was a sudden change in heaven and earth, with the moon setting and the sun rising, and a scorching sun hanging in the air for five thousand years. The dominant Blue Moon Grass, who had survived the Dark Wu period, began a large-scale extinction of species. Among them, the weak branch of Blue Moon Grass, the Purple Zhao Grass, unexpectedly rose from the sky and became the protagonist of the era that dominated the era
