Qiao Hua didn't expect that he could run so fast, like a raging wind, driving the yellow leaves on the ground to fly up one after another, at first glance, it looks quite like the style of a hero in a martial arts movie.

Thinking about it in hindsight, Qiao Hua felt that this must also be because of the strength of his limbs. The dwarf tyrannosaurus now leaps almost twice as far as it used to, and its legs run faster and faster, and if it had had been carrying a glider behind it, it would have been flying long ago.

"Bang dang dang!"

The big monster watched as the dwarf tyrannosaurus not far away suddenly ran towards it at a speed of more than a hundred kilometers per hour after less than two seconds of lifting, faster than any animal it had ever seen.

it!

Too fast and the weight of his body produced a huge inertia forward, and the guide Qiao Hua couldn't stop for a while, and watched his huge body jump up suddenly, and stepped on the monster's body at once.

"Poof!"

The poor monster was about to open its mouth when the dwarf tyrannosaurus jumped behind it, and then a terrible pain came from its back.

“%*#a&……”

The monster made a high-frequency sound and wanted to turn its head, but it found that its body was completely out of control. And Qiao Hua, who finally stopped, looked back and knew that this monster was no longer saved.

The other party's flat body has been bent into an incredible arc, and the back has sunken a large piece, and it seems that the spine should be broken.

In fact, it is quite normal for this to happen - a matter weighing several tons is stepped on its body, and I am afraid that no animal will escape the fate of crushing bones to pieces. However, Qiao Hua felt that this victory was too fucking dramatic, and he was still a little confused.

Several mouthfuls of blood spat out of the monster's mouth, and then its body gradually curled up into a ball. Qiao Hua slowly moved over and stabbed the spear in his hand hard at the neck before finally ending its life.

It wasn't until this time that Qiao Hua finally had the opportunity to take a good look at the monster in front of him. On the whole, the creature in front of him is more like a mammal, but his habits are very similar to that of amphibians, not only can he hold his breath underwater for a long time, but the salty sea water seems to have no effect on him.

Thinking of this, Qiao Hua vaguely felt that a kind of ancient creature he had heard of before seemed to meet such conditions.

Whale walking.

As the name suggests, this creature is actually a walking whale, which is the appearance of the whale's limbs before it is completely degenerate, not only able to swim in the water, but also to go ashore to hunt small birds and beasts, and is the sea 6 overlord of the early Cenozoic era and the same name as the crocodile.

Could this be the legendary whale walker?

Qiao Hua looked around the corpse and looked at it, but still felt that this thing was far from the whale he imagined. The thing in front of him is really too different from the whales of later generations, both in terms of size and appearance.

After thinking about it carefully, many of the large animals after the emergence of Qiao Hua's current human beings seem to have evolved from very small animals in the early Cenozoic Era, and as for these large creatures living on the earth now, except for a very few that can survive for tens of millions of years, most of the rest have become extinct with climate changes.

Looking at it this way, Qiao Hua showed a pattern that shocked him.

From an evolutionary point of view, the evolution of living things is to better adapt to the needs of the environment, and only in continuous evolution can we adapt to the development of nature. However, the fact is that after many species have evolved to a certain level of size and ability, they have reached a bottleneck, flourishing and declining, and gradually going extinct.

Reptiles evolved into dinosaurs and became extinct; Small mammals evolved into large animals such as meso-clawed beasts and crown-toothed beasts, which became extinct; The feline evolved into a saber-toothed tiger and became extinct......

According to the theory of evolution, animals will become more adaptable to the needs of the environment in the process of evolution, but many animals that have evolved more perfectly have been abandoned by nature again and again, while weak animals have survived the survival of the fittest again and again, and entered the next round of "evolution-extinction" cycle.

Qiao Hua had always thought that Gaia's consciousness was an exhibition to protect the earth, but now it is unreasonable: when a species evolves to a very high level, it will inevitably become the dominant force on the earth, posing a huge threat to other species. Gaia consciousness that in order to maintain the balance of species on Earth, after a certain amount of evolution of a species will not only inhibit its evolution, but even use the forces of nature to cause it to perish.

So there's a strange cycle in which nature keeps species evolving, killing them after a certain amount of evolution, and then supporting another wave of weaker species to evolve.

Qiao Hua thought it was a big joke. All animals are vying to be at the top of the food chain, but they don't know that when they reach the top, extinction awaits them.

"Ahh

"Squeak-"

While Qiao Huawu was thinking to himself, the bean paste and the fruit pit had already run from under the tree. Although the two little ones stood by and watched the fight between the dwarf tyrannosaurus, they all became very excited when they saw the fight, because it proved that they could eat fresh meat again. Especially the kernel, seeing that the skin of this walking whale is so delicate, it is natural to guess that its flesh must also be excellent.

Qiao Hua didn't have much interest in this walking whale, because from time to time the scene of this guy eating carrion would appear in his mind, and his stomach would churn. So the dwarf tyrannosaurus walked to the river with his spear in his hand, stirring it up in the river, using the power of the water to wash away the half-dried blood on the spear.

The water of the river looks very clear. Qiao Hua looked at the broken starlight inside, and suddenly became interested, and suddenly buried his head in the deep river water, and used the starlight to see the large and small fish swimming in the water.

Under the starlight, the crystal clear river water radiates a variety of magnificent colors; Large and small fish swim around, some with beautiful patterns; A sea snake with black and white rings snaked past Qiao Hua, wriggling towards the opposite shore like an accordion.

Qiao Hua felt very comfortable looking at such a scene, the cool river water made his whole body cool down quickly, and the nervous and troubled mood just now gradually disappeared.

But just as he lifted his head out of the water, he suddenly saw a very small red dot appear on the surface of the river, and then gradually spread.
