Shepherding Humanity

　　The long-term pain, the torture of chemotherapy, the death of his parents, let Xu Zhi feel physically and mentally exhausted, and even began to wonder why his boring life was for. Now, before he died, he suddenly had curiosity.

　　The evolution and progress of living things.

　　 "They are all near death, this big brother has already hung up, then I stepped into the footsteps of her death, use this ability, in the orchard, to make an evolutionary sandbox to play?"

　　 He smiled, "It feels like a sandbox game, Minecraft."

　　 turned out the dusty tricycle in the corner, panting like a bald old man, and his body hollowed out by chemotherapy struggled to drive outside the town. He spent his 30,000 or 40,000 savings, and pulled back a bunch of farmyards to sort out the equipment and instruments, and returned to the courtyard.

　　 The place of the selected sand table is not big, it is a place of 100 square meters.

　　 He picked up the **** and pulled up the water pipe, like a farmer digging a pit, shaping small soil mountains, fresh water rivers, caves, and various barren terrain.

　　 took out the purchased high-temperature ejector, an inch-inch high-temperature grilled whole sand table, to clean up potential plants and animals, so that the existing earth creatures do not affect the evolution of spore species...

　　 And the microorganisms do not need to pay attention, it is difficult to understand, they will be swallowed by Zerg genes, and evolved into a new earth species.

The origin of the species is the ocean.

　　Finally, in the middle of the sand table, he built a 40-square-meter man-made huge pond, poured in the salt he bought, and made the ocean according to the proportion of salt water.

　　 However, a difficult problem appeared.

　　 This is not a round planet, but a square flat sand table of 100 square meters. The structure of this land is the topographic structure in ancient mythology:

　　 The place where the sky is round.

　　 "Is the land in mythology?" Xu Zhi scratched his head, his body was not as good as before, and he had a difficult time to organize it for a week before he prepared the entire huge sand table of 100 square meters. This morning, he controlled the parasite of the worm nest, and began to produce large pieces of single cells that belonged to the Zerg initial evolution: spores, which were injected into the sand table he shaped, in the central ocean.

　　Evolution started.

　　He gave instructions to the mother nest:

　　 "Acceleration of cell division: ten thousand times!"

　　According to the counting unit of Zerg, it is doubled to one year.

　　 10,000 times faster, the day of these creatures is equivalent to 10,000 years...but it is not yet known whether new species can be born in the small courtyard sand table to achieve the Cambrian explosion of the year.

　　 After all, time is different.

　　 This sand table world is located in the yard, and on the sky of the yard, the alternation of the sun and the moon cannot be changed, and one day accelerates into 10,000 years.

　　Long night and sunlight, day and night of 5,000 years each alternate, what kind of species will be born in this special harsh living environment?

　　 On the first day, there was no change in the clear pond in the center, no change.

　　 The next day, the whole sand table was quiet.

　　 The third day.

　　 The fourth day.

　　 Finally arrived on the fifth day, the whole central ocean he designed began to appear with some plankton, and the water began to be cloudy with the naked eye.

　　 On the sixth day, to a visible degree, those species began to evolve into plankton-like green creatures the size of fleas, the green symbol of life, and began to spread throughout the artificial ocean, full of vitality.

　　 "Mother's nest, began to set a genetic lock to limit the size of spore organisms!"

　　 Xu Zhi frowned, and quietly gave orders, the yard was so big, it was impossible to let them evolve too much.

　　Although according to the long evolutionary history of the earth’s biology, it is impossible for large species to appear in the early stage, everyone is plankton and microbial body type, but it must be limited in advance and prepared.

　　 And the memory of the previous mother worm also showed a huge body evolution, which was wrong.

　　 There is no need to deliberately expand the Zerg's body size. Maintaining the original worm's young body size is the correct way of evolution. The smaller the body size, the easier it is to produce qualitative changes in energy.

　　 Their size no longer expands.

　　 Since then, the zerg size of the normal species in the sand table is the size of ants, which is the real worm, zerg. The largest species, even if it evolved to the level of a dinosaur, would not be bigger than a cat.

　　 A worm, the size of a cat, is already an exaggerated thing, and a sand table of 100 square meters is the size of a small province for ant-shaped micro-ecological creatures.

　　 On the sixth day, the upheaval finally began.

　　The long accumulated evolutionary history of 3.8 billion years ago was condensed in the first five days, the sunrise on the sixth day, the Earth-like Cambrian biological explosion, began! !

　　A large number of various plankton grow and reproduce in the ocean, begin to occupy the entire ocean in large quantities, and then fight each other to compete for survival space.

In just one day, Xu Zhi seemed to be watching an accelerated ecological disciplinary film. On this land, continuous creatures were born in a few seconds, from childhood, growth period, aging period, and then perished, giving birth to the next generation... .

　　 The seawater also began to become cloudy.

　　 Pieces of various aquatic plants float.

　　 "But it's getting dark, and my biggest worry is that the world of sand table will be destroyed..."

　　 He looked at the artificial sand table in the yard, and looked up to the dark sky. At dusk, afterglow under the corner of the wall, the world gradually fell, as if the end came.

　　 Cell division evolution is accelerated 10,000 times, after all, it is not a natural evolution of years. He condensed 10,000 years into a day in reality, which is equivalent to 5,000 years in the day and 5,000 nights.

　　 For five thousand years of night, these newly born aquatic plants will lose photosynthesis and will die directly.

　　 Unless, these aquatic plants evolved plants that can photosynthesize at night.

　　 just got into the night.

　　 There have been drastic changes in the sea water. The plants did not receive sunlight during their growth. Within a few seconds, they withered, ashed, sunk to the bottom of the sea, and lost their lives.

　　Widely sinking into the seabed.

　　Like the Dead Sea, there is no life under the night.

"The first biological extinction, UU reading www.uukanshu.com began...I didn't expect it to be so fast." Xu Zhi took a deep breath. During the long era of evolution, the earth has experienced five species extinctions, the most famous nature. It was the mass extinction of the Cretaceous creatures, the destruction of the dinosaur era, when 80% of the animals died.

　　 The first biological extinction of the earth was actually the end of the Ordovician.

　　 That was because of the sudden drop in temperature and the decrease in sea level, which caused the destruction of the earth’s marine ecosystem and directly exterminated 85% of the marine species at that time.

　　 What is different from the Earth Age is that the sand table under his hands suddenly fell into darkness for five thousand years at night and lost direct sunlight, which caused the first extinction of the sand table species.

　　 "Hold on, my spores!!"

　　 Xu Zhi sat quietly beside the yard and looked at the ocean in front of him, "My world, don't just evolve aquatic plants, because they are directly extinct because there is no direct sunlight..."

　　Earth is a huge planet, among which billions of species have survived and eliminated, and it has huge compatibility, even if the biological extinction can survive.

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

According to the truth, even if it fills the pond, there are only hundreds of thousands. According to Darwin’s theory of evolution, very few biological bases are not enough to evolve a new creature that adapts to the environment. The paper may be full of expectations. That's the evolutionary species evolved from the Zerg cells with terrible adaptability!

　　 He waited quietly.

　　The moonlight spilled from the yard, and the lifeless ocean full of plant corpses passed half an hour. Suddenly a touch of light blue surfaced.

　　 A new species was born...

　　Start photosynthesis of moonlight!
