Becoming a creator in prehistory

Chapter 4 Reshaping the original ecology

At the time of the outbreak of microorganisms, Yuan Chu took Luka away from the ocean and returned to the land.

At this time, the earth is still barren of grass, not even soil, and the only thing that can be seen is the granite crust that has been baptized by lava and has become as hard as iron.

The evolution of life needs the support of the external environment. In such a barren land, it takes a long time to see plants, animals, and even humans appear.

Instead of being bored and bored, it is better to actively transform the original ecology of the earth to make it more suitable for the reproduction of life.

And as an eternal immortal who transcended everything, Yuan Chu also has the ability to do this.

"Luca, don't run around."

The first time she stepped on the ground, Luca was full of curiosity about everything around her, but after hearing the call, she ran back obediently with two "braids" swinging, and rubbed on Yuan Chu affectionately.

Since the fungal core was transplanted, her body size has ushered in a second growth, and at this time it is already half the size of the fungal shell.

Not only that, she also gained special abilities because of it.

At this time, Yuan Chu wrapped up a bacterium with a flagellum, and then handed it to Luka.

"Luka, I want you to turn it into a structure that can absorb light and heat."

Upon hearing this, Luca stretched out two flagella on her body and took the bacteria over.

She swallowed the bacteria into her body like eating jelly beans, and after a couple of chomps, she spit them out again.

At this time, the physiological structure of this bacterium has undergone major changes.

That's right, Luca's ability can reorganize life. Her body is a melting pot of life, and she can change the structure of the target at will.

However, so far, this ability is not as easy to use as imagined.

"Luka, you're mistaken. What I want is chloroplasts that can carry out photosynthesis, not melanin."

When Luca heard this, she "looked" suspiciously at the dark bacteria on the ground, and her two flagella almost curled into question marks.

Seeing this, Yuan Chu secretly sighed. Although Luca's intelligence level has improved, it is still only at the level of an infant. She can't understand the difference between chloroplast and melanin at all.

Yuan Chu had no choice but to conduct a temporary teaching of seeing pictures and objects, dragging Luca to talk to the sun in the sky, and it took a long time for her to understand his general intentions.

Then, after several failures, Luca finally synthesized the bacterial sample he needed.

The synthetic bacteria are blue-green in color and shaped like pearls on a string.

That's right, this kind of bacteria is the famous blue-green algae.

Historically, it used to rely on photosynthesis to bring the earth from an anaerobic state to an aerobic state.

Since we choose to actively improve the earth's ecology, blue-green algae are naturally indispensable.

It has to be said that Luca's ability saved him a lot of effort.

Place the cyanobacteria in a well-lit place and let it reproduce.

Then, Yuan Chu wrapped Luca with a fungal shell, and then drilled in through a crack in the granite ground.

As he entered the gap, a large area of ​​cracks unexpectedly appeared on the entire granite ground.

At this time, Yuan Chu, who had gone deep into the ground, had changed drastically.

I saw that the flagella behind him turned into hyphae, and it stretched and expanded underground. The granite structure would break at the touch of a touch, and it could not hinder the growth of mycelium at all.

Mycelium is the true form of fungi. Fungal mycelium in nature can produce up to ten times the tire pressure, and can completely crush solid rocks independently.

Not to mention that the fungal shell is inherently immortal, and no matter how hard the stratum is, it is still bean curd in front of its mycelium.

As long as Yuan Chu wanted to do it, it would be easy to use mycelium to penetrate the center of the earth.

Of course, he is not that boring yet. All he is doing now is just to reshape the surface and rock layers, paving the way for reshaping the earth's ecology.

And the microorganisms that are all over the earth have become the nourishment for his mycelium growth.

From ancient times to the present, there have been many behemoths on the earth, but the biggest one is not a whale or a dinosaur, but the most inconspicuous fungus.

The largest fungus in the world has a hyphae area of ​​900 million square meters, which is equivalent to 1300 football fields. No creature can compare with fungi.

At this time, under Yuan Chu's control, the infinitely growing mycelium was like an earth dragon, and he almost turned the entire earth's crust over.

At the same time, the enzymes and decomposing enzymes secreted by the mycelia decompose and refine the hard geology.

The mountains were pushed down, the ravines were filled, and the surface of the earth ushered in a great change that was countless times more violent than the crustal movement.

However, during this process, Yuan Chu also encountered a little trouble.

He originally thought that when the microorganisms were consumed by him as nutrients, the number would decrease to a certain extent, and then give the blue-green algae, the latecomers, more space to reproduce.

Still, he somewhat underestimated how quickly bacterial colonies could reproduce.

Assuming that a bacterium has a 100% survival rate of division and reproduction, it only takes about a day to cover the surface of the earth.

Even if the division survival rate is cut to 50%, it will only take less than 5 days to achieve the above goal.

With such a strong reproductive ability, Yuan Chu's plans naturally came to nothing.

When more than half of the "plowing" work on his side has been completed, the number of blue-green algae is still not improving.

Seeing this situation, Yuan Chu could only choose to enlarge his moves.

With the help of Luca, he created several viruses targeting mainstream bacteria.

The microbial community generally follows a rule, that is, the simpler the structure, the faster the reproduction speed.

Therefore, fungi are inferior to bacteria, and bacteria are inferior to viruses.

The reproduction speed of viruses is several orders of magnitude higher than that of bacteria, and due to the particularity of life and non-life, viruses will not actively seize the living space, so it is perfect to use it to solve this problem.

Sure enough, under the precise strike of the phage, the number of bacteria suddenly dropped, and the reproduction speed of cyanobacteria began to rise linearly.

At the same time, under the photosynthesis of cyanobacteria, the oxygen content on the earth also began to soar.

As a kind of anaerobic bacteria, cyanobacteria will die on a large scale when the oxygen content of the earth reaches the threshold.

However, Yuan Chu had no intention of letting them withdraw from the stage of history.

Bacteria were suppressed by phages, resulting in a sudden drop in the number, and he needed to replace his meal ticket again, and Spirulina was the prostitute he identified.

Therefore, he controlled the mycelium of fungi and began to parasite cyanobacteria on a large scale. He provided shelter for cyanobacteria so that they would not burp in an oxygen-rich environment.

In this way, a wonderful symbiont called lichen appeared.

They attach to the surface of rock and gravel, and promote soil production with special acidic substances.

In order to make the composition of the atmosphere more uniform and layered, Yuan Chu controlled the hyphae to roll up and part of the lichen to rise up from the ground, forming a tree-like shape.

…………

After [-] million years of careful carving, the earth is no longer what it used to be.

Different from the later generations with luxuriant grass and green trees, the earth at this time is more wild and mysterious under the background of the fungal trees and various huge fungi piercing into the sky.

In order to transform the earth, the fungal shell has been completely transformed into mycelium, which means that Yuan Chu can no longer move freely with his flagella like before.

However, he didn't pay much attention to it.

After all, the hyphae of fungi are almost all over the world. These hyphae are like Avatar's braids, which have made him everywhere, and it doesn't make much sense to him whether he can move it.

Today, various indicators such as air, soil, and temperature have met the basic requirements for biological reproduction.

The transformation of the earth's ecology can temporarily come to an end, and he is ready to personally unveil the curtain of the emergence of life...
