Qiao Hua didn't expect that he could run at such a fast speed, like a violent wind, causing the yellow leaves on the ground to fly up. At first glance, he looked like a hero in a martial arts movie. Thinking about it afterwards, Qiao Hua felt that this must also be because his body strength had become stronger. The distance the dwarf tyrannosaurus can now take a step forward is almost twice as long as before, and the running frequency of its legs has become faster. If it had been carrying a glider behind it, it would have already been flying by now. "Bang, bang, bang, bang, bang!" The big monster watched helplessly as the dwarf tyrannosaurus not far away suddenly ran towards him at a speed of more than 100 kilometers per hour after gaining speed for less than two seconds, faster than it had ever done before. It runs faster than any animal I have ever seen. Damn it! The excessive speed and heavy body weight created a huge forward inertia, causing Qiao Hua to be unable to stop for a moment. He watched as his huge body jumped up and stepped over the monster. . "Pfft!" Just as the poor monster was about to open its mouth, the dwarf tyrannosaurus had already jumped behind it, and then a horrible pain came from its back. "%*#@&" The monster made a high-frequency sound and wanted to turn its head, but found that its body was completely out of control. Qiao Hua, who finally stopped, looked back and knew that this monster was hopeless. The opponent¡¯s flat body has been bent into an incredible arc, and a large piece of his back is dented. It looks like his spine should be broken. In fact, this situation is completely normal - if something weighing several tons steps over the body, I am afraid that no animal can escape the fate of having its bones crushed into pieces. However, Qiao Hua felt that this victory was too damn dramatic, and he was still a little confused. The monster spit out a few mouthfuls of blood from its mouth, and then its body gradually curled up into a ball. Qiao Hua slowly moved over and stabbed its neck hard with the spear in his hand, finally ending its life. It was only at this time that Qiao Hua finally had the opportunity to take a good look at the appearance of the monster in front of him. On the whole, the guy in front of him is more like a mammal, but his habits are very similar to amphibians. Not only can he hold his breath underwater for a long time, but it seems that the salty seawater has no effect on him. Thinking of this, Qiao Hua vaguely felt that an ancient creature he had heard of before seemed to meet such conditions. ??Walking. As the name suggests, this creature is actually a walking whale. It is what the whale's limbs looked like before they were completely degenerated. Not only can it swim in the water, but it can also go ashore to hunt small birds and beasts. It is the overlord of the sea and land as famous as the crocodile in the early Cenozoic Era. . Is this the legendary walking whale? Qiao Hua looked around the body again and again, still feeling that this thing was far from the walking whale he imagined. The thing in front of me, both in terms of size and appearance, is really very different from the whales of later generations. After thinking about it carefully, Qiao Hua discovered that many large animals after the emergence of humans seemed to have evolved from very small animals in the early Cenozoic Era. As for the large creatures currently living on the earth, except for a few that can exist in the tens of millions. Years later, most of the remaining species became extinct due to climate change. Looking at it this way, Qiao Hua discovered a pattern that shocked him. From an evolutionary perspective, organisms evolve to better adapt to the needs of the environment. Only through continuous evolution can they adapt to the development of nature. However, the fact is that after the body size and abilities of many species have evolved to a certain level, they have reached a bottleneck, flourishing and declining, and gradually dying out. Reptiles evolved into dinosaurs through layers of evolution and became extinct; small mammals evolved into large animals such as mesonychus and crown-toothed animals and became extinct; cats evolved into saber-toothed tigers and became extinct According to the theory of evolution, animals are evolving In the process, they will become more adaptable to the needs of the environment. However, many well-evolved animals have been abandoned by nature again and again, while smaller animals have survived the survival of the fittest time and time again and entered the next round of "evolution - ¡ªin the cycle of destruction. Qiao Hua used to think that Gaia consciousness was protecting the development of the earth, but now he discovered its irrationality: when a species evolves to a very high level, it will inevitably become the dominant force on the earth and exert influence on other species. pose a huge threat. In order to maintain the balance of species on earth, Gaia's consciousness will not only inhibit the evolution of a species after it evolves to a certain level, but will even use the power of nature to destroy it. So it appeared.Such a strange cycle: nature allows species to continuously evolve, kills them after they evolve to a certain level, and then supports another wave of vulnerable species to evolve. Qiao Hua thinks this is a big joke. All animals are vying to be at the top of the food chain, but little do they know that when they reach the top, extinction will be waiting for them. "Ah wu¡ª¡ª" "Zhijijiji¡ª¡ª" While Qiao Hua was thinking to himself, the bean paste and fruit core had already ran over from under the tree. Although these two little guys stood by and watched the fight between the dwarf tyrannosaurs, they all became very excited when the fight was over, because it proved that they could eat fresh meat again. Especially the core. Seeing that the skin of this walking whale is so delicate, it is natural to guess that its meat must also be of excellent quality. Qiao Hua, however, had no 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 also churn. So the dwarf tyrannosaurus carried the spear to the river, stirred it up in the river, and used the power of the current to wash away the half-dried blood on the spear. The river water looks very clear. Qiao Hua looked at the broken stars inside and suddenly became interested. He buried his head in the deep river water and used the starlight to see the large and small fish swimming underwater. Under the starlight, the crystal clear river exudes various magnificent colors; large and small fish swim around, some with beautiful patterns on their bodies; a sea snake covered with black and white rings winds its way from Qiao Hua swam past, squirming towards the other side like an accordion. Qiao Hua felt very comfortable looking at this scene. The cool river water quickly cooled down his whole body, and the nervous and upset mood just now gradually disappeared. But just after he raised his head from the water, he suddenly saw a very small red dot appear on the river, and then gradually spread.
