While constantly shattering the rocks and making soil, Guo Sen did not forget to observe the small creatures in the salt water lake.

They have reproduced a considerable number of populations during this period.

The point that was placed at the lake was less than ten square meters in size, but now it has grown to control the territory of nearly 100 square meters, and is still expanding.

As for the seaweeds with super reproductive ability, they even extended their tentacles to a position close to the center of the lake. Their existence floating on the water surface even gradually dyed the blue lake water green.

At the bottom of the lake, some aquatic plants as thick as needles grew, dancing with the waves. Guo Sen even saw that some multicellular organisms were living here, which was not the case before.

Near the center of the lake, Guo Sen also found a considerable number of single-celled organisms swimming constantly, just like the Little Green and Little Red, but the species seemed to be more diverse.

Guo Sen was delighted 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 vitality.

He has squandered so much energy, and this is the reward.

With a sense of relief, Guo Sen carefully looked at his main target - those multicellular creatures.

The number is enough, and he can start experimenting again to allow these little guys to accelerate the evolution process again!

Surprisingly, more species of multicellular organisms appear in the lake.

Guo Sen counted and found that compared with before, there were more than 20 carnivorous multicellular organisms, while there were nearly 100 herbivorous multicellular organisms, even if they were not counted in detail, there were nearly 100!

He was very excited, and life seemed to be moving forward in a more prosperous direction!

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

Should we choose a small part to do the experiment, or all of them are included?

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

Collective co-evolution can make the entire ecosystem more balanced than individual evolutions.

He quickly selected two lucky people and selected a strange guy with six tentacles and two spikes on his mouth from the carnivorous multicellular creatures. Guo Sen called it a "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 like a ruler. It is worth noting that there is a strange bulge at the tail, and its name is naturally the ruler monster.

"Okay, the experiment begins soon, if it goes well..."

Guo Sen suppressed his excitement and immediately started the operation.

His thoughts were exactly the same as last time, which was to use the spirit of stirring up trouble, so that both parties began to have a sense of crisis, and then they began to evolve wildly!

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

The ruler monster swam to a gathering place of Xiaohong under his control and provoked it. When the little reds and the others surrounded him and were about to wander, its tail suddenly flashed automatically!

Immediately afterwards, the group of little red people seemed to be dead and stopped moving at all!

"Damn?"

Before Guo Sen could react, the other little reds who surrounded him began to tear up the bodies of these dead little reds...

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

Its tail flashed again, and the little reds stopped moving as if they were dead.

Now, Guo Sen understood.

The tail of the ruler monster will be automatically discharged in a crisis!

When did this evolve? It makes no sense to be charged?

He looked at the little greens again, looked at each type carefully, and after checking a lot, he found something extraordinary.

These guys seem to have evolved various characteristics of bull batches!

The protective color hidden in the seaweed is hidden, and a bunch of flagella grows to make the speed very fast, and the guy with an extremely hard appearance is fighting with the little reds...

After looking at Xiaohong's community carefully, he even found 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 too much of what he wanted to do.

Obviously he did not intervene, these guys have evolved so quickly, far beyond his imagination.

Before they evolved from single-cell organisms to multicellular organisms, they all had single repetitive characteristics and seemed simple creatures. After they arrived at multi-cell organisms, they ushered in a big explosion of evolution!

It is more complex and practical.

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

Expand their population in a further way!

This group of multicellular organisms only reproduce and survive in the saltwater lake. The overall area of ​​Guo Sen's sphere is tens of thousands of times larger than that of this saltwater lake!

The birth of life is absolutely not enough by the evolution of a small group.

Only by constantly expanding the group can the evolution of these small lives be further promoted.

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

His sphere is extremely large in size and the ocean accounts for a considerable proportion. Relying on the characteristic that these multicellular organisms generally live near the seashore, Guo Sen first placed part of it near the coast not far away.

He observed for a while and found that the difference in the waves here was not very obvious, so there shouldn't be any tsunami or something like that.

Guo Sen started moving.

After the creatures in this area grew, he moved part of this place to another place.

This process lasted for quite a long time.

When these little guys lived in almost all the waters suitable for survival, Guo Sen even discovered that some of them had even evolved into bone-like things...

He felt that there was no need to do anything else in evolution.

What you should do is to give them a suitable environment for survival.

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

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

That is, the temperature of the entire planet seems to have dropped too much than before!

It had been maintained at a uniform temperature of 40 degrees or 50 degrees before, but now it is less than 20 degrees...

Guo Sen was also found the culprit immediately.

It was an ice field that should be located at the north and south poles. Now it is gradually developing in the opposite direction, and even extending to a location near the center of the sphere...

"Ice Age? That's what it is called?" Guo Sen quickly remembered this term.

What is accompanied by the ice age is the extinction of life populations!

The plants that have finally landed on temperature will definitely not survive the invasion of low temperatures, and the little guys in the ocean are even more so.

A countermeasure must be made.

"Volcanoes, let's erupt again!"
Chapter completed!
