As the planet cools dramatically, the conversion of heat into melanin becomes less efficient.

Next is the age of the stars, and the frequency of planets, comets, and meteorites visiting the Earth will skyrocket.

Although Yuan Chu will not be stoned to death by meteorites, he is also disturbed from time to time.

After much consideration, he decided to move on to the primordial ocean for the time being.

After some tossing, he landed on the surface of the sea.

At this time, the sea water is mixed with a large number of minerals, and there is no sign of life.

There was nothing to pay attention to in such a pool of stagnant water, and Yuan Chu immediately shook the flagella behind him and swam towards the depths of the water body.

The further downstream, the warmer the water becomes, and as you go deeper, rows and rows of black chimneys appear on the ocean floor.

Although the collision of the planet Theia has caused the temperature of the earth to drop a lot, the geological activity has never stopped, but in a relatively mild way.

The chimney-like hydrothermal vents slowly release sulfides that spread through the water like real smoke, creating a wonderful chemical reaction with the alkaline seawater.

Substances called amino acids were born in this environment.

Yuan Chu was overjoyed to see these hot springs under the sea, this was the place he had planned to settle down, and it was also the canteen he had found for himself.

I saw that he shook his flagella vigorously and swam all the way over.

Then a smoke exhaust pore of about the same size was selected on the chimney and the fungal shell was directly blocked.

Amino acids passed him in a steady stream of smoke and water, and they could be easily captured.

His former scientific knowledge came into play again, using amino acids to synthesize proteins in the body like building blocks, which can be absorbed by the fungal body.

If it used to be a rationed fast food in the sky, now it's an all-you-can-eat buffet.

The disadvantage is that the food is a semi-finished product and needs to be processed by yourself.

However, even if there is an additional process to convert proteins, it is more efficient than absorbing heat before.

After settling down, Yuan Chu not only "cooked" for himself every day, but also paid attention to the changes in the surrounding environment in his spare time.

Amino acids are the building blocks of life, and these primordial oceans are the easiest places to give birth to life.

As a former researcher, he is curious about the process of the birth of life from nothing.

It's like a bottle of amino acid facial cleanser, no matter how long it is left out, it won't come back to life.

In addition to the necessary material conditions, a hidden element is also needed to sublimate matter into life, and then complete the breakthrough from zero to one.

Yuan Chu wanted to see what the hidden elements of the primitive soup in front of him were stirring up and constituting life.

As time passed, everything in the water remained the same, with amino acids and minerals still suspended lifelessly.

On the contrary, the inner wall of the pores where Yuan Chu lived was gradually covered by a layer of oil film.

Looking at this special substance, Yuan Chu's mood was a little complicated for a while.

He knew that it was the most critical lipid that made up the cell membrane, formed by protein residues excreted by the fungal shell combined with other substances in the water.

The agent of life he wanted to observe was none other than himself.

Although life has its own way to flourish, according to the course of history, no matter how you think about it, the first life should not burst out under his influence.

At this moment, Yuan Chu realized the change he had made to the world.

Even if he had walked 4.5 billion years in time, future generations might have been unrecognizable.

What's more, the influence of the ancestors of life on earth may lead to the complete disappearance of the human species from the source.

As soon as he thought of this possibility, and then looked at the new life next to him that was gradually taking shape with the pores of the rock as the womb, his heart suddenly cooled.

Feeling the fungal shell inside him, he also acted at the same time.

I saw that the cell membrane on the surface of the fungus began to concave inward, like a big open mouth, constantly approaching the little life.

Yuan Chu wanted to eat it as a way to erase the influence he might have on future generations.

At the last minute, however, he hesitated.

Looking at the cell membrane struggling to spread on the inner wall of the pores, and the translucent cytoplasm beating like a heart, Yuan Chu could feel that it was trying to be born into this world.

Especially when he saw it sticking out its unformed flagella and groping towards him like a curious child, he finally put away his "fangs".

"Well, what if we go back in time to the old era?

As far as the eternal and immortal me is concerned, the future is just a flash in the pan, and since I am just a passerby, then why care. ”

After figuring it out, Yuan Chu no longer had any scruples about changing the future, he not only took the initiative to provide protein as nutrients for the little life, but also used the captured amino acids to assist it in building the core.

Watching a new life grow under his care, he actually had the joy of being a parent at this moment.

The little one is not very large, about one-tenth the size of a fungal shell.

And as the most primitive life, its internal structure is also very simple, far from being comparable to the fungal body.

However, there is one thing that the shell has to bow to, and that is that it has two flagella.

When swimming in the water, it shakes like a pair of small pigtails, and it looks ugly and funny.

However, Yuan Chu has been watching it for a long time, but he feels that the ugliness reveals a bit of cuteness.

"Since the ancestor of life on earth is called Luca, then I will also name you Luca."

With Luca's intelligence, it was naturally impossible to understand what the name was.

Although she didn't understand anything, she still swam to Yuan Chu's side and rubbed the fungal shell with her body, showing great attachment.

However, life comes to the world with a mission, and instinct drives them to reproduce, and as the origin of life on Earth, Luca is no exception.

Not long after she was born, she spontaneously split her core and began to reproduce in the form of replication.

For a rudimentary single-celled organism, this way of reproducing is undoubtedly suicidal.

In less than a day, the ribosomes in Luka's body were missing to varying degrees due to errors in replication.

Looking at Luca's tattered body, Yuan Chu couldn't help but feel a little distressed.

"That's enough, Luca.

You've done what you're supposed to do, and let your children do the work for you. ”

Then, using his consciousness, Yuan Chu forcibly scraped a small piece of tissue from the core of the fungal shell, and then implanted it into Luca's body to help her repair the broken core.

With his help, Luca's body has regained and her intelligence has improved visibly, at least she can remember her name for now.

What made Yuan Chu even more relieved was that the process of reproduction of life on earth was not broken by Luca's withdrawal.

Once the wheel of life turns, it will not stop because of a single goal, but will turn faster and faster under the inertia of life's desire for rebirth.

In less than a year, the water of the primeval ocean where Yuan Chu lived was full of microorganisms.

There are offspring that are identical to Luca, but there are also individuals whose structure has changed dramatically due to errors in replication.

The diversity of life begins with these mutated individuals, and among them the most primitive bacteria and viruses have emerged.

In the coming months, they will sweep the globe and unleash a microbial frenzy no less than the Cambrian explosion of life.

However, Yuan Chu felt that these were not enough.

What is most missing is often what the heart desires the most.

He had been lonely for too long, desperate to bring the earth to life.

Now that you've accepted the changes that may happen in the future, you might as well go a little more thoroughly......
