Qiao Hua immediately continued to watch with bated breath. Sure enough, after waiting for about a minute, a gray body about three meters long slowly climbed to the shore. As usual, the whale in front of him was in a completely crazy state. After landing, he looked around and then crawled straight towards Qiao Hua. This dwarf tyrannosaurus is very interested in this. It might be understandable if these walking whales had a head-to-head fight with the bear, because after all, they are all about three meters in length, so the walking whales still have some chance of winning. But now this walking whale is running towards his dwarf tyrannosaurus so confidently, and it looks menacing and full of confidence. This made him really confused. This is not seeking death - it is simply committing suicide. Qiao Hua really didn't have the patience to wait for it to climb here, so he simply ran two steps directly to the shore and attacked it from the side. Although the walking whale wanted to bite Qiao Hua, due to the limitations of its body, it tried several times but could not even touch the skin of the dwarf tyrannosaurus. In the end, Qiao Hua's sharp teeth bit his head, killing him quickly. But Qiao Hua, who won the victory, did not feel any joy. With his current ability, it is too easy to deal with an animal of this size and attack power. What surprised Qiao Hua was the whale's frantic reaction. Before Qiao Hua became a dinosaur, he once fed a white mouse hallucinogenic drugs for biological experiments. Looking back now, he found that the current reaction of the walking whale was exactly the same as that of the white mouse back then. It was crazy and highly aggressive, and it didn't even have any fear of its natural enemies. But why did these walking whales become like this? And the time they climb ashore every time is also very interesting, it seems to be at low tide. Qiao Hua thought, it couldn¡¯t be that these walking whales had eaten marijuana before landing, so they became so crazy. Just when the dwarf tyrannosaurus was carefully looking at the body of the walking whale on the ground with a puzzled look, a strong wind suddenly rolled over quickly from behind. Qiao Hua suddenly felt a chill on his head. When he looked up, he saw that the turtle shell hat on his head had been blown several meters away by the strong wind, and drifted towards the center of the sea with the receding tide. Hold! Qiao Hua cherishes his hat very much. It can protect you from the sun when you are hot, hold water when you are thirsty, and can also protect against falling objects. It is not easy to find such a multi-functional hat in the new generation. You should know that turtle shells are easy to find, but turtle shells of this size are difficult to find. So the dwarf tyrannosaurus immediately dived into the sea water. Now that he has the ability to breathe underwater, Qiao Hua feels that he should learn to adapt to living underwater in the future, and he can also take this opportunity to learn more about marine life. Just when Qiao Hua was having such a beautiful imagination, and using the power in his body to force the respiratory tract on the surface of his body to open to receive oxygen from the water, he suddenly realized that something was wrong. The originally cool mind suddenly became very dull, like a machine bearing that has not been used for many years. A very low-pitched sound came from his ears, like a huge hammer hitting his big head. This low-frequency sound wave made Qiao Hua feel dizzy almost instantly, and his whole head felt like it was going to explode. But in order to pick up his turtle shell hat, he could only endure the extreme discomfort in his body and continue swimming towards the cluster of green in front of him. Finally, after chasing for twenty or thirty meters, Qiao Hua finally put the big turtle shell on his head again. However, at this time, his consciousness had become extremely confused, and he even felt that the light in front of him was gradually fading away just like the last time he was in deep water. The ground twisted into a ball, like various paints mixed together. This dwarf tyrannosaurus felt like the monkey subdued by Guanyin, being tortured to death by the tight curse. Fortunately for him, even under such circumstances, he still did not lose his sense of direction and mobility, which allowed him to endure the pain and quickly return to the shore. On the beach, Qiao Hua ran wildly. It seemed that only such a release could make him feel better. After about five minutes, the dwarf tyrannosaurus gradually woke up from the chaos, and the powerful roar like a tractor in its head also disappeared. What happened just now? Qiao Hua came back to his senses and felt surprised in his heart. He recalled it carefully. It seems that I was fine before I used the ability to breathe underwater, but after opening the airway located all over the skin, I couldn't. Could it have happened in between?What happened? In order to find out the truth of the matter, this dwarf tyrannosaurus actually chose to dive into the sea again. He first held his breath and stayed inside as usual, and found that there was nothing special. Immediately, when Qiao Hua tried to open the skin's airway, his head roared again. "Poof!" Qiao Hua quickly returned to the water and let out a long breath. After a while, my mind became clear again. After figuring out the conditions that triggered this feeling, the whole thing made Qiao Hua even more confused. ??Looking at it just like that, the condition for producing this feeling is to open the skin and respiratory tract. But Qiao Hua remembered that he had opened this respiratory tract for a long time in the sea in the afternoon, and he didn't feel any discomfort at that time. Why couldn't he do it now? Qiao Hua suddenly felt vaguely that the whale coming ashore to commit suicide for no reason might have something to do with what he was going through now. Based on the sounds he heard in his ears and the feelings reflected on his body, combined with the strange behavior of the walking whales, Qiao Hua guessed that this thing underwater was probably a kind of infrasound wave. And this kind of sound wave should only occur when the tide is low. But this has created a series of problems. Since it is an infrasound wave that animals can feel, why haven¡¯t I felt it before, and why haven¡¯t the underwater fish had any abnormal reactions to it? Qiao Hua found that he only felt the existence of this sound wave after opening the skin respiratory system. Before that, he didn't feel anything. Judging from the behavior of walking whales, it is obvious that they can also feel the existence of this infrasound wave in the water. The part of the dwarf tyrannosaur's mind responsible for reasoning quickly agitated. Since neither terrestrial animals nor aquatic animals can feel the existence of this kind of sound wave, they can feel it after opening their respiratory tract in the water, and whales can also feel it. This shows that this kind of infrasound wave is only special to themselves and whales. "Amphibian" works.
