The arrival of darkness has plunged everything into a dead silence.

It was a terrible disaster.

For hundreds of thousands of years, since the first scavengers appeared, life in this world has been bathed in warm sunlight.

They evolved eyes to discern enemies and food through the reflection of light.

They have evolved thermothermal systems that rely on the temperature of sunlight to raise their body temperature.

They evolved photosynthetic systems that use light energy and carbon dioxide to synthesize organic matter and release oxygen.

Oxygen, on the other hand, provides a suitable living environment for a variety of other living forms.

But without sunlight, these evolutions lose their meaning.

So when the eternal night came, a large number of creatures began to become extinct.

First and foremost is cyanobacteria.

This creature, which can be called the cornerstone of the entire small courtyard world, died in a large area after losing the energy supply of sunlight.

The water, which used to glow with blue light, has become turbid and dull.

However, there is one place where this is not the case.

In the eternal night, in addition to the moon and stars in the sky, there is also a heavenly fire, burning on the south shore of the endless sea.

If you look at it from a bird's-eye angle, you will see that it is above the small dragon pit in the summoner's canyon.

And on the "C" shaped mountain range that surrounds Xiaolongkeng, a ghostly figure is tirelessly busy.

Xiaolongkeng, or Penglai Bay in Hongjun's diary, now gathers the hope of this world.

When the sun has not yet set, a little light of the heavenly fire is of little importance to this world.

But when night comes, this light of heavenly fire is the key to the survival of cyanobacteria.

As early as thousands of years ago, Hongjun has been raising blue-green algae in Penglai Bay one after another.

To be precise, it's not just breeding, it's keeping seeds.

Cyanobacteria have been around for tens of thousands of years.

In this long period of time, they have already differentiated into many subspecies.

Hongjun wasn't sure which subspecies was better suited to the relatively faint glow of the Skyfire.

In order to fulfill the entrustment of the true god, he spent hundreds of years traveling on both sides of the endless sea, and preserved some strains of various cyanobacteria in Penglai Bay.

It's not that Hongjun is far-sighted and intelligent.

It is true that it took two hundred and fifty years to cultivate the consummation realm in the Nether Realm, and finally ascended.

Hongjun is certainly not a stupid person.

But even if you are not a smart person, if you have been thinking about something for thousands of years, you will definitely be able to plan ahead.

......

Another 10,000 years have passed.

In the Pangu Temple, the faint lights flickered.

Hongjun sat in front of the desk, recording in detail the performance of various cyanobacteria in the face of the catastrophe, and at the same time drawing a map of the two sides of the endless sea.

He writes in the leather of a sea beast that went extinct three thousand years ago.

Although they adapted to the darkness, they evolved to devour plankton.

But because their leather was tough and soft, long-lasting and not rotten, they became extinct.

Died in the hunt of Hongjun.

They became extinct and became the bearers of the history of the eternal night.

For burying a species with his own hands, Hongjun has no sorrow, no joy, and no guilt.

Raising and breeding these sea beasts will involve too much experience in this eternal night.

And the Lord God did not say that he would protect them.

Then they must also serve to fulfill the instructions of the true God.

So, Hongjun mercilessly turned them into his own manuscript paper.

......

Thirty thousand years have passed.

There is still no light in the sky.

The length of the eternal night was longer than Hongjun had expected.

But he was not discouraged.

Because the fire above his head was still bright.

This shows that everything was expected by the true God.

In Penglai Bay, 80 percent of the blue-green algae has died.

The remaining cyanobacteria all belong to the same subspecies.

Hongjun calls it a legacy species.

This subspecies of cyanobacteria has a special variation that allows them to make better use of light energy.

Hongjun found that these cyanobacteria still did not stop evolving.

Vaguely, they seem to be becoming different from each other again.

......

Sixty thousand years have passed.

The sky fire is still bright.

But the lights in the Pangu Temple have not been lit for a long time.

Even after thousands of years of storage, the grease used to light the lamps in the Pangu Temple has dried up.

Hongjun sat on the stone sill, recording the recent changes in Penglai Bay by the light of the heavenly fire.

This "recent" has been going on for more than two thousand years.

The remaining species of cyanobacteria have diverged greatly, becoming two separate species, and have embarked on completely different forks in the road.

A type of cyanobacteria has further strengthened its ability to harness light energy, and the number is increasing.

Another species of cyanobacteria, which evolved roots, stems and leaves, changed the way they lived with the tide and began to take root along the shores of the bay.

Hongjun recorded every drop of this on the animal skin.

His handwriting is small.

Because the hides are running out.

He stroked one stroke at a time, with great neatness and great piety.

Hongjun seems to be praying to the true God, expressing his pious heart to the omnipotent God.

He believed that although the True God was asleep, his divine thoughts would be able to feel his own sincerity.

Suddenly, Hongjun frowned.

He put down his pen and disappeared in place.

......

In Penglai Bay, a slender red figure is making waves.

It voraciously gulped all kinds of food in the water, which was an abundance of food that could not be enjoyed elsewhere in the Endless Sea.

"Evil beast!"

Hongjun snorted coldly, and as soon as his palm flipped over, a small snail rose in the wind, and in a blink of an eye, it had become the size of a mountain.

This snail is the one that Zhang Zifan threw in casually that day...... The little snail inside.

When the breeding season of snails arrives, it is normal for a large snail to have a few small snails.

The one Zhang Zifan lost, there was a poor cub in it.

This cub had already died of red burning, but the snail shell it left behind before its death was refined by Hongjun for tens of thousands of years and became his natal magic weapon.
