After surviving the scorching sun of the day, the night of the seventh day began to fall.

The purple grass still lives in the ocean with peace of mind, and it has been able to withstand the alternating sun and moon for 5,000 years.

At the same time, along with its mass reproduction, the photosynthesis of these aquatic plants has led to a significant increase in the oxygen content of seawater, and the conditions suitable for the birth of marine animals have been met.

In nature, if there are no aquatic plants in the water, and it cannot flow, it is difficult for the oxygen in the air to integrate into the water, so that the stagnant water cannot produce a suitable aquatic animal environment.

Soon, the spores and single-celled organisms in the oceans of the sand table world began to evolve, and the first to appear was a group of black beetles, similar in shape to the ancient Paleozoic marine species of the earth, horseshoe crabs.

At this point, marine animals have entered the historical stage of the evolutionary era.

"Minecraft Sandbox...... Marine animals, finally evolved from a single cell, I have been waiting for you for a long time, waiting for two mass extinctions. ”

The moment he saw the animal appear, Xu Zhi showed a relieved smile, and his tired body after staying up for a day and a night finally couldn't bear it, so he went back to the room directly, lay down and fell asleep.

When he woke up, it was already the eighth day of the creation of the spores' evolutionary sandbox.

Anyone who has studied biology knows that the ocean is the origin of life, but Xu Zhi found that there were already marine animals, which began to be dissatisfied with the fierce competition in the ocean, and gradually evolved toes, skin scales, and evolved into amphibians, living on the barren coast.

Seeing this, he recorded the back page of the Guangwu era with beautiful handwriting.

This evolutionary third epoch should be completely reborn after the mass extinction, and Xu Shi named it the Cenozoic:

[Cenozoic, the era ushered in a new life, all kinds of animals exploded, the first batch of marine animals appeared, the species was prosperous, the group competed, invertebrates relied on the carapace, dominated the sea for a while, became the overlord of the era, but never dominated for too long, vertebrates were born, with the advantage of dexterity, they were defeated, vertebrates became the overlords of the Cenozoic period, climbed out of the ocean, and will rule a long era!]

Xu Shi finished writing everything and silently closed the book.

The epochs on Earth are the Cambrian, Ordovician, Silurian periods...

And the epochs of Xu Paper are the Dark Martial Era, the Guangwu Era, and the New Era...

"It's so fast, I slept all night, the spores, I'm about to go out of the ocean and evolve terrestrial species..."

Xu Zhi suddenly frowned, "However, to evolve intelligent creatures, I don't know how many long epochs it will take, since the ecosystem has appeared, it is better for me..."

"Something?"

He looked at his fingers, and wanted to cut his hand and drip blood into it, so that some species could absorb genes and quickly evolve humanoid intelligent creatures...

In the sand table ocean in the courtyard of the orchard, there is a beautiful mermaid Naga?

On the sand table mountains and rivers in the orchard yard, there is a strong Zhi Ape Taishan clan?

"It's exciting to think about, a miniature sand table world in the yard. ”

However, he vetoed it again, and some resisted using humans as experiments to evolve intelligent species, "I remember that there is a zoo in the urban area outside, secretly get a few orangutan fur, get some genetic templates, and do something......"

He went straight out the door.

A few hours later, Xu Zhi entered the zoo, and a couple of couples around him showed their affection in pairs, or a family of three, and their parents showed their affection while bringing their children to the zoo to play.

He's a single dog, and he's very eye-catching.

After all, who comes to the zoo alone to see the monkeys? It's easy to be seen as a monkey.

A family of three whispered secretly.

"Daddy, look at this uncle... Bald, he looks, so strong!"

"Don't talk about people like that, he's bald, he doesn't look strong, he probably has a disease, otherwise he is not so old, a seriously ill patient comes to the zoo alone, no matter how you think about it, he is a poor person, no one accompanies him..."

Xu Zhi, a young man in his early twenties, has obvious strong side effects from chemotherapy, is too old, and his hair is thinning, but he is pitiful....

He used to be quite pitiful, but now he's having a good time, and it's cool to evolve the species.

"Hehe, believe it or not, I, a bald young man, evolved a long black hair the next day, modified the evolutionary genes, cured cancer, and regained his youth?"

"But I don't believe it myself, evolution is too slow, my orchard is still in the Paleozoic era of the sea and land. He studied in the orangutan garden for a while, took a fancy to a male gorilla with the best physique, went directly to the administrator, and simply and rudely said that he was a medical student at a nearby university, had a research topic given by his supervisor, needed orangutan blood, and wrote a graduate thesis.

"The young man said that you are an assistant to the professor in the laboratory, a top student, and a very knowledgeable person.... I believe. The uncle looked at Xu Paper's sparse hair, and also sighed and pity, "But it's impossible to ask for the orangutan blood I raised, it was raised by me, and I treat it like a son, even if you threaten me, stuff me with money, and bribe my leader, I can't..."

"A tube of blood. ”

Xu took out 3,000 pieces of paper and placed them on the table.

Uncle Administrator's eyes were bright, this was his salary for a month, and he couldn't help but jump up and say, "Just take a tube of blood? I can take a few more tubes." ”

"Big brother, I just need to take care of it. ”

Xu Zhi said with a smile.

He stroked the scarce hair on his head with his palm, and smiled like a demon who induces people to fall, "Don't worry, I won't tell your leader, if possible, we will cooperate in the future, for example, I am very interested in the blood of peacocks and white cranes in your zoo." ”

"Yes, yes. The uncle rubbed his palms excitedly, "It is a very meaningful thing to support college students in researching biology topics. ”

After a while, Xu Zhi left very calmly.

After taking care of the orchard by himself, he will not enjoy the remaining hundreds of thousands of savings, and as long as he is not generous in a short time, he will not be able to use it up.

He has a lot of money, and his baldness has become stronger! He already has the ability to make money, but he is so arrogant!

Then he thought about it, and on the side of the road, he got a little bit of termites that he just saw, after all, ant genes are infinitely powerful, and they are still free....

At about five o'clock in the afternoon, when he returned to the front of the courtyard, Xu Zhi was suddenly stopped:

"Hey, you're Xu Paper??"

Xu Paper turned his head and looked at the roadside in the countryside, and a beautiful girl riding a battery car looked at herself.

"I'm Chen Xi, the one who used to come to your house when I was a child, I recently saw that the lights in your yard were on at night, and I really came back?" The girl couldn't help but be surprised, "How did you become like this?

Chen Xi?

Xu Zhi remembered a little, "It's because of stomach cancer, hair loss, mental malaise, and chemotherapy." ”

"You have cancer, how could it be..."She stared at Xu Shi with wide eyes, and was speechless for a while.

She suddenly said: I was also admitted to university last year, and it is also your one...

"Bless you. ”

Xu Zhi nodded, and now she remembered that it should be summer vacation, and she was here when she went back to her hometown for the holiday.

As soon as the thought passed, Xu Zhi was in a hurry to go back, after all, he was not there for half a day, and he didn't know, those Zerg species with extremely terrifying reproduction power, what the hell they evolved into!

He was desperate before.

Silently waiting for death, now the boring life has become unknown and interesting.

He's too excited now!

Reproducing species and creating life is like taking medicine, and you can entertain yourself.

"You're leaving. Chen Xi didn't stop either, it was a little complicated.

Pursing her lips, she looked at the idol she had been trying to catch up with back then, obviously running away, and now she is optimistic, all pretending.

After all, bald!

He's bald!!

This rare amount of hair makes me feel distressed when I think about it!

Chen Xi suddenly felt that the dream he had been chasing had collapsed, but he could still be friends, so he shouted loudly from afar, "Hey, if you have time to come to my house to play, if you have anything, you can also come and discuss with us." ”

.....

Xu Paper's braincase hurts.

Why did everyone stare at my head and make a sad expression of remembrance, I said, the sequelae of chemotherapy, is it a normal operation?

Even if the cancer is not cured, now that the chemotherapy has stopped and gradually recovered, the hair will still grow back!

"Hehe, it's time to evolve a powerful species that doesn't grow hair, and let them taste the terrifying power of baldness!" Xu Paper scratched his head, returned to the courtyard, and looked at the pond.

At this moment, another half a day has passed.

After the species climbed onto the land, the extremely terrifying rate of reproduction covered almost the entire 100-acre miniature sand table, the mountains and rivers were full of greenery, the plains were also overgrown with strange-shaped trees, and there were animals swimming in the rivers.

"There are fish in freshwater, and marine fish have left saltwater and developed into freshwater rivers. ”

"It only took them 10 days to evolve from a single cell to this complex multicellular level, achieving biodiversity and evolving into an ecological world, which is simply a terrible rate of reproduction and evolution. ”

This is already a small sand table ecological world, if it weren't for the fact that the insect nest limited the breeding range and could not go out, it was afraid that it would cause species invasion on the earth.

"So, let me start picking a lucky one at random now, carry out the mass extinction treatment, add the genes of orangutans and ants, and be born after passing it, and become my ancient insect ape family in the Paleozoic era in the sand table in the yard..."

Wearing the blue plastic shoe covers he bought, Xu Zhi walked into this huge 100-acre experimental field, and along the way, he didn't know how many ant-sized green trees and animals he trampled to death.

He didn't care.

"This is natural selection, survival of the fittest, and being trampled to death by me can only mean that you are unlucky and eliminated by nature. He crouched down and silently looked at each species, "Screen one of the most promising ones and evolve into a wise ape." ”

He thought for a moment and added.

"Well, it's better to be bald. ”
