Chapter 138: 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 its scene from birth, to growth, and then to prosperity.

In just an instant...

These mosses, gymnosperms, and angiosperms 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 glanced at the source that was burning fiercely in space.

One portion of the source can 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.

Moreover.

Their volume changed from being short and small at the beginning to becoming increasingly tall.

In order to absorb enough sunlight.

They grew vigorously.

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

The entire land changed from the green it had at the beginning to colorful hues.

The 270 millionth year.

Because of the massive appearance of plants.

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

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

It can 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 due to 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, reproducing crazily.

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

Its speed of reproduction was very astonishing.

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

The 320 millionth year.

The arthropods still hadn't finished eating the rich nutrients left behind by the death of the algae.

Based on the legacy of their predecessors, they continued to evolve. ===== CHAPTER 140 =====
