Chapter 47: Cambrian period, the explosion of life! [Seventh Update]

Green began to spread on the land.

Under the acceleration of time.

Qin Mu witnessed with his own eyes the scene of it from birth, to growth, and then to prosperity.

In just an instant...

These moss, gymnosperm, and angiosperm plants crawled all over the land.

This desolate planet, after 250 million years of evolution, finally saw the appearance of a large number of plants!

"The source has already been consumed by half..."

Qin Mu looked up.

He looked at the source burning fiercely in space.

One portion of the source could accelerate the world for 500 million years.

According to the current situation.

There were still 250 million years remaining.

According to the system's deduction, it should be enough to evolve intelligent organisms.

He took a deep breath.

Qin Mu continued to observe.

The 260 millionth year.

Plant species became increasingly diverse, freely evolving into tens of thousands of varieties.

And.

Their volume, from the initial shortness, became increasingly tall.

In order to absorb enough sunlight.

They grew vigorously.

During this process, flowers, grass, and trees were thus generated.

The entire land, from the initial green, changed into colorful hues.

The 270 millionth year.

Because of the large appearance of plants.

All gases harmful to the existence of life in the atmosphere were completely purified.

The climatic environment also became increasingly suitable for life to survive.

It could be said that the appearance of plants made a great contribution to the later appearance of life forms.

The 300 millionth year.

The ocean filled with blue-green algae finally experienced a large-scale extinction phenomenon because of the eutrophication of seawater!

Algae died on a large scale.

The ocean became a forbidden zone for plants.

But...

This was also a huge opportunity.

The death of algae itself provided the ocean with rich nutrients.

Thereby causing...

Single-celled organisms to evolve again!

A brand-new, tiny arthropod appeared!

It swam freely in the ocean, proliferating crazily.

Because there were no natural enemies, plus sufficient food...

Its speed of proliferation was very astonishing.

This type of arthropod soon became the new round of hegemons in the ocean.

The 320 millionth year.

Arthropods still hadn't finished eating the rich nutrients left behind by the extinction of algae.

Based on the legacy of their predecessors, they continued to evolve.

Categorized, there appeared protozoa, echinoderms, mollusks, flatworms, annelids, coelenterates, etc.

The species became increasingly prosperous.

And their body size, the largest, was no bigger than a little finger.

At the same time.

They had a common characteristic: no spine.

So they were also called invertebrates!

Qin Mu stood on the coast, looking at the ocean where one generation of newcomers replaced the old.

His expression was joyful.

The large-scale prosperity of invertebrate organisms...

Meant that vertebrate organisms were not far away!

This would be a qualitative leap!

The 350 millionth year.

Invertebrate organisms had occupied the entire ocean.

Because food was becoming less and less.

Therefore, they were forced to attack each other, using other species as food.

The battle began.

And weak species were destined to not get food or become someone else's meal.

Evolution, under these circumstances, was forced to happen again.

They began to actively arm their body surfaces.

Making their shells increasingly hard.

While protecting themselves, they could also hunt better.

Therefore, more and more crustacean organisms appeared.

They...

Became the new round of hegemons.

The 370 millionth year.

Crustacean organisms became more and more numerous, ruling the ocean.

Similarly.

Internal competition began again.

Other species had all become strong.

They couldn't get food again...

Therefore.

Evolution was forced to occur again.

They no longer strengthened their own shells, but strengthened the interior of their bodies.

A spine quietly generated!

Possessing a spine, they would gain faster speed, stronger digestive ability, and more terrifying bite force.

Among this type of organism, primitive fish led the tide of the era.

Among them.

Placoderms and acanthodians became the new hegemons of marine life because of their strong defense and attack.

The 360 millionth year.

Qin Mu stood before the endless coastline.

He saw the most spectacular scene since evolution had begun for so long.

This period of time.

Was also the period of accumulation and development for all species on Blue Star.

Because of the combined effect of many factors.

In these ten million years.

Vertebrate organisms underwent earth-shaking changes.

Categorized, tens of thousands of different vertebrate organisms were born.

They filled every part of the ocean, showing different biological potential.

A portion of them...

Even came directly to the coastline, walking toward the land.

Evolving into amphibious reptiles!

Qin Mu stood beside the coastline.

Every moment he could see a large number of organisms crawling out of the ocean and entering the land.

Like light and shadow.

"This... could perhaps be equated to the Cambrian explosion of life."

Qin Mu took a deep breath and couldn't help but mutter.

Indeed.

The explosion of species diversity during this period had already exceeded all the periods he had evolved before.

Reptiles appeared, active everywhere on land.

Birds flying in the sky also appeared during this period!

They flapped their wings and flew high, soaring in the sky.

Enjoying the blue sky that belonged to them to their heart's content.

The 380 millionth year.

After a period of reproduction.

Land organisms became the hegemons of Blue Star.

Birds and reptiles began to rule the very top of the food chain.

The representative of this was large organisms like dinosaurs.

The 390 millionth year.

Dinosaurs were still the hegemons on Blue Star.

The 400 millionth year.

Dinosaurs still occupied the very top of the land organism food chain.

The 410 millionth year.

Qin Mu discovered...

The status of the dinosaur hegemon was very stable.

They reproduced rapidly, crazily eating other species.

Causing biological reproduction and evolution to become slower and slower.

Qin Mu, seeing this, couldn't help but frown.

If this continued...

His 500 million years of acceleration would be used up, and he still wouldn't have evolved intelligent organisms.

Therefore.

He took a deep breath.

With a single thought.

Imitating the scene that had once happened on Earth before he transmigrated, he summoned a large number of meteorites from outside the sky!

Those meteorites drifting in cosmic space.

Transformed into meteors.

Falling ruthlessly onto the land.

Forming a terrifying extinction disaster.
