While crushing rocks to create soil, Guo Sen did not forget to observe the small creatures in the saltwater lake.

They have multiplied in a considerable number during this time.

At the beginning, it was less than 10 square meters in size by the lake, but now it has grown to control nearly 100 square meters of territory, and it is still expanding.

As for the seaweeds, which are super reproductive, they even extend their tentacles close to the center of the lake, and their presence on the surface of the water even gradually dyes the blue water of the lake green.

At the bottom of the lake near the shore, some aquatic plants as thick as needles also grow, fluttering with the waves, Guo Sen even saw that there were also some multicellular organisms inhabiting here, which was a phenomenon that did not exist before.

In the vicinity of the middle of the lake, Guo Sen also found a considerable number of single-celled organisms constantly swimming, just like the original Little Green and Little Red, but there seemed to be a greater variety of species.

Guo Sen was pleased to see that this small ecosystem seemed to be constantly repairing and growing under the baptism of time.

Gradually, the entire saltwater lake is full of life.

He wasted so much energy, and that's the reward.

With a sense of relief, Guo Sen looked carefully at his main targets, the multicellular organisms.

There were enough of them, and he could start experimenting again, so that the little ones could start the process of accelerating their evolution again!

Surprisingly, it seems that a greater variety of multicellular organisms have appeared in the lake.

Guo Sen counted, compared to before, there are more than 20 kinds of carnivorous multicellular organisms, and there are nearly 100 kinds of herbivorous multicellular organisms, even if you don't count them in detail!

He was excited, and life seemed to be striding in a more prosperous direction!

However, this also caused some difficulties for the experiments he was going to do.

Should a small number be selected for the experiment, or should all of them be included?

Guo Sen hesitated for a moment, and decided to include all the multicellular organisms together.

Collective co-evolution is more balanced than individual evolution.

He quickly selected two lucky ones, from the carnivorous multicellular creatures selected a strange guy with six tentacles and two spikes on the side of his mouth, Guo Sen called it "Six-legged Monster", as for the herbivorous side, Guo Sen still pursued the advantage of speed this time, and found a guy with a head like a blue sphere, and the rest of the body like a ruler, it is worth noting that it also has a strange bulge on its tail, and its name is naturally a ruler monster.

"Alright, the experiment will start right away, if it goes well......"

Guo Sen suppressed his excitement and immediately started the operation.

His idea is the same as last time, that is, to use the spirit of agitation to make both parties begin to have a sense of crisis, and then each of them will start to evolve wildly!

However, what Guo Sen didn't expect was that he soon encountered an accident.

The ruler monster came to a gathering place of little red under his control, and provoked it, and when the little red people surrounded him and was just about to swim away, its tail suddenly flashed automatically!

Immediately afterward, the group of little reds seemed to be dead, completely unmoving!

"?"

Before Guo Sen could react, the other Xiaohongs who came around began to tear up the bodies of Xiaohong, who looked like they were dead......

Guo Sen looked at the ruler monster and controlled it to get closer to a few little reds, and when it was about to be caught......

Its tail flashed again, and the little reds stood still as if they were dead.

Now, Guo Sen can see it.

The tail of the ruler monster will automatically discharge in times of crisis!

When did this evolve? There is no reason for such a thing as being electrified, right?

He looked at the greens again, looked at each species carefully, and after examining a large circle, he found something very remarkable.

These guys seem to have evolved a variety of cattle batch characteristics!

Hidden in the seaweed, the protective color is hidden, a bunch of flagella grows to make it extremely fast, and the guy with an extremely hard appearance is stiff with the little reds......

Looking closely at Xiaohong's community, he even noticed the existence of a guy with fangs almost all over his body......

Guo Sen looked at these and suddenly felt that there didn't seem to be much to do that he wanted to do.

Obviously he didn't interfere, these guys have evolved so fast, far beyond their imagination.

Before the evolution of single-celled organisms to multicellular organisms, they were all simple-looking organisms with a single repeating feature. After the arrival of multicellular organisms, it ushered in a great explosion of evolution!

It continues to evolve in a more complex and practical direction.

Guo Sen thought for a while and decided not to do experiments to promote modernization, but chose another route.

Expand the number of their groups even further!

It is not enough for these multicellular organisms to thrive in saltwater lakes, and the entire area of the ocean on his sphere is tens of thousands of times larger than this saltwater lake!

The birth of life is never enough by the evolution of a small group.

Only by constantly expanding the group can we further promote the evolution of these little creatures.

Guo Sen made up his mind and began to carefully select the types of these small creatures and find a new habitat.

His sphere area is unusually large, and the ocean accounts for a considerable proportion, relying on the fact that these multicellular organisms generally live near the sea, Guo Sen first put some of them near the coast.

He observed for a while, and the difference in the height of the waves here was not too obvious, and there should be no tsunami or anything like that.

Guo Sen began to move.

When the creatures in the area had multiplied, he moved some of them to another place.

This process lasted quite a long time.

When almost all the water suitable for survival was inhabited by these little creatures, Guo Sen even discovered that some of them even evolved something similar to bones......

He felt that he really didn't need to do anything more when it came to evolution.

What should be done is to give them a suitable environment for survival.

As a planet, this is what Guo Sen does best.

Looking up at the global environment, he suddenly found something that he had completely ignored!

That's the temperature of the whole planet, it seems to have dropped too much than before!

It used to be at a uniform temperature of 40 or 50 degrees, but now it is less than 20 degrees......

The culprit, Guo Sen also found it immediately.

The ice sheet, which was supposed to be located at the north and south poles, is now growing in opposite directions, even extending to a distance from the center of the sphere......

"Ice age? That's what it's called, right? Guo Sen quickly remembered the term.

The Ice Age was accompanied by the extinction of life populations!

Those plants that rely on temperature to survive will definitely not survive the invasion of low temperatures, and even more so for the little ones in the ocean.

A response must be made.

"Volcanoes, erupt again!"

Hellfire erupted from Guo Sen's land and sea in an instant, and began to reheat his planet, which had become cold!
