They always believe in their own theories.

Therefore they are always in the midst of war.

They can't end themselves.

There can only be external forces to stop this endless war.

This external force is the 'recession virus'.

A virus that does not know why it exists on ancient land.

Because of the curiosity and exploration of the land, a group of dark algae infects the virus and passes them to the entire ocean.

Like a plague, the virus has a devastating force.

Although the dark algae group has dealt with countless viruses and archaea in the sea, they are not resistant to this virus.

These viruses will not kill them, they will only make them...recession.

Although dark algae are not even multi-cellular organisms, they have extremely developed nervous systems, which is why they can make a lot of complicated thinking.

But under the infection of this virus, their nervous system began to decline rapidly.

Their nervous system is like the reverse evolution, becoming more and more simple and more primitive from complexity.

Initially, algae could notice its own decline, and then slowly...not even enough intelligence to notice that it was declining.

There are a lot of dark algae groups who noticed the decline of other groups. They didn't know the reason at first. They thought it was a good opportunity to attack immediately. As a result, they were also infected... and entered the recession stage.

Some dark algae that know the cause try to stay away from all kinds of similarities and look for ways to fight the virus and study these viruses.

And they also created a set of theories to analyze the characteristics of these viruses and how they appear.

Many uninfected algae are trying to study the virus, but the war at this time has not stopped.

Because when the uninfected groups of dark algae encounter each other, they often feel that the other side's theory of the virus is wrong.

Then these two groups will fight, and each group believes that their theory is correct and they can deal with the virus.

They have no idea of ​​cooperation... never.

At the moment when this species was born, it seemed that there was no peace at all between different consciousnesses.

Even if there have been some bad algae in history, they want to use their own theories to convince the same kind, rather than complement each other's mistakes.

As a result, these small numbers survived, and the uninfected group also died in the battle.

As for those infected groups... they are still alive.

There is not enough intelligence to think about various theories, and of course there will be no more fighting.

The complex neural structure degenerates into a simple ganglion, and the large dark algae community cannot sustain the previous group consciousness and slowly disappears.

Only a few dark algae survived.

They are those in the 'biological weapons' they make.

A lot of dark algae have ever produced a variety of biological weapons, these creatures are generally made with suitable fungi, while the dark algae is to be in the center to act as a conductor.

After their nerves began to decline, these dark algae survived in the weapon, and their nerves did not completely disappear. They could still send simple instructions to direct the biological weapons to find food.

As a result, they survived. In the long life, the dark algae have been mixed with the biological weapons they are riding and become...the same species.

According to speculation, these biological weapons later became the oldest... multicellular organisms with neural structures.

Then slowly evolved into some of the later creatures on Ershi, such as... octopus.

There are also many Ershi people who have said this: In ancient times, the ‘brain’ was the parasite of the ‘body’, slowly controlling the body and eventually co-evolving into a creature.

However, this is only a guess, and the real situation has not been recorded.

After all, after the recession, there is no dark algae to keep the wisdom to live on Ershi.

So is the story of dark algae so over?

It is not over.

Although they did not continue to live on Ershi, they lived in some other places.

The dark algae did not completely die. In the recession, some groups started to travel around the world in order to escape the virus and find a way out.

In order to find a safe place, there is no militant area with no virus.

Dark algae usually live in waters above 100 meters deep, so this group of dark algae begins to move deep into the water, trying to find a place where there is no danger.

They believe in some of the theories and legends that they have imagined, and they believe that there must be a place for them to live.

They have gone through deep oceans in the search process, and they have created some 'armor' to allow them to access various environments that are not suitable for them.

Finally, they found light in the deep sea...

Through that light, they went to a mysterious place, this place... also like the ocean, but nothing.

Accurately speaking, there is no living thing... there is no other kind, and there are no common archaea, it is an empty place.

But there are a lot of nutrients that can make them live for a long, long time.

They think they have realized their ideas, so they stayed here and lived.

They began to imagine that, as in the past, these dark algae continued their previous imagination after they had been idle.

Give theory to the various phenomena of this new world, think about the meaning of life, and ponder over the militant characteristics of their species.

This place seems to have unlimited space and time to give them unlimited imagination.

But this time they are not just imagination.

For some ideas, they will start to experiment and experiment, and begin to try to make tools... and experiment with various things.

In this world without war, they carry out countless imaginations and experiments.

Although there were no other creatures, some trials could not be completed, so they took ... to test themselves.

But this is a wrong decision.

After all, dark algae is a species that will consciously divide.

If a group is divided into two halves, their consciousness will be divided into two halves.

It may be nothing at first, because their theories are the same and they can coexist peacefully for a while.

But after a long time, the theoretical thinking of these two consciousness will be biased, and then they will blame each other's mistakes, and...

Fight again.

Even if they were originally a bad group, they would have a different sense of personality after they split.

Some of the experiments they did... led to the separation of the population.

It also led to the emergence of new consciousness.

Only this time the war was carried out in a very interesting environment.

A world that can easily reach the 'rules'.
