Completely opposite to the fiery color just now, all the big mushrooms suddenly turned light yellow, just like the yellow canopy above the emperor's head when traveling. Qiao Hua's heart was full of confusion. He had heard that plant leaves would rotate in the direction of the sun, but this was the first time he had seen a plant that could change color. And the change from fiery red to golden yellow is too obvious. The interest in this dwarf tyrannosaurus was immediately aroused, and he observed it curiously for a long time. During this period, these huge mushrooms changed from yellow to light green, and the color gradually deepened. Qiao Hua guessed that the color change of this big mushroom is likely to follow the order of the spectrum, and the change is based on the difference in absorbed heat. As for why it had such an effect, he only had a few conjectures and was not sure. Qiao Hua originally wanted to observe it for a while, but found that he had no chance this time, because the waves rising on the sea reminded him that it was high tide time, and now he was still more than 20 miles away from the shore. Swimming this way is not an easy task, so he must try his best to catch this ride. In the surging waves, Qiao Hua swam up and down. The forward rolling tide and its strong body make this dwarf tyrannosaurus move extremely fast, giving it the appearance of a good swimmer. It¡¯s just that the sea breeze kept pouring into his nose and mouth, which really made him feel a little uncomfortable. After Qiao Hua roughly determined his position, he simply buried his entire body in the sea water and moved forward quickly in a diving posture. The swimming fish that kept advancing along with the rolling waves were left behind by this uninvited guest in the sea. Finally, a guy who looked like a swordfish at the front was also caught up by Qiao Hua. The latter flicked his head and knocked the proud underwater formula car aside, because the unlucky fish blocked it. His way. But after about half an hour of sneaking underwater, Qiao Hua suddenly felt that something strange had happened to his body. This feeling is amazing. Qiao Hua felt as if he was absorbing something from the water, and the cells on his skin seemed to have changed into another state in an instant. They were no longer closed to the outside world, but became a channel for contact between the inside of the body and the outside world. Although this change is not very obvious, the body of this dwarf tyrannosaurus has excellent perception, and it has captured the information conveyed by the body immediately. He could conclude that this was not caused by interference from external factors. Qiao Hua couldn't help but lower his head and look under him. What he saw seemed to be nothing different from usual. But the changes he could perceive became more and more intense as time went by. The originally tense lungs gradually relaxed for some unknown reason, as if they had lost their effectiveness in this space. A light flashed in the dwarf tyrannosaur's mind. Are you relying on your skin to breathe underwater? Qiao Hua suddenly felt that his heart began to beat wildly. Darling, this is what I have dreamed of! "If it were normal times, being in such an excited mood would inevitably cause him to consume oxygen extremely quickly. However, at this time, all Qiao Hua could feel was the regular and small contraction of the surface tissues. If you didn't feel it very keenly, you wouldn't even be able to notice it at all. Moreover, after another period of time, the dwarf tyrannosaurus couldn't help but open its mouth and spit out some waste gas circulating in the body. If it were normal times, he would never give up until he squeezed out every last drop of oxygen. After a period of adaptation, Qiao Hua roughly guessed the principle of the breathing mechanism he was currently using based on his physical feelings. If you guessed correctly, your skin, stimulated by strong water pressure and guided by certain aquatic animal genes in your body, can filter out water molecules while allowing oxygen to pass through. Oxygen enters tissue cells from channels everywhere, and then enters capillaries distributed throughout the body. After merging with blood, it participates in the circulation of the entire body. This dwarf tyrannosaurus experimented many times and found that this skin breathing mechanism could not be turned on at any time. The prerequisite is that you must be underwater and be under a certain amount of pressure, whether it is external pressure or pressure from yourself. To explain it vividly, these breathing channels on the skin can be compared to a kind of pressure valve. When the pressure is high enough, it will automatically open and close automatically when the pressure is lost. And this kind of channel is one-way, you can only enter but not exit. " In this way, Qiao Hua quickly thought that the reason why he sheds his skin these days may be because he wants to open this skin after the skin is replaced.Because of the suction channel. It was not until this moment that the dwarf tyrannosaurus finally noticed a problem that he had ignored today. ¡°I plunged into the seawater in the morning and didn¡¯t wake up until noon and emerged from the water. The whole process took half a day. My longest record of holding my breath before this was only about an hour, and there had been no major breakthroughs. If you guessed correctly, you should have unlocked the genetic lock for underwater breathing after molting, but after sleeping in the water for such a long time today, you still didn't notice this. "I'm so stupid, really" At this time, only Sister Xianglin's famous quotation could express Qiao Hua's speechless mood. With the push of the tide and the crazy speed, it took only two hours for the dwarf tyrannosaurus to return to the shore from the island. Fortunately, the current only carried it vertically away from the coast. After Qiao Hua swam to the surface, he found his base on the shore without much effort. What makes this dwarf tyrannosaurus strange is that a group of small figures actually appeared under the tree where the fruit core was. When he got closer, Qiao Hua realized that it was a group of small bears. Doujiang was among them, playing and teasing with one of the big dogs and bears. "Ouch¡ª¡ª" There are also a few little bears who are obviously very interested in the little squirrels on the tree, and they keep raising their heads and roaring. ¡°Zhijijiji¡ª¡ª¡± The core was lying tightly on the tree, and it seemed that he was very afraid of the group of little things with sharp canine teeth below. However, when he looked up unintentionally, the little squirrel suddenly caught a glimpse of a green figure with a turtle shell floating on its head in the sea. His eyes suddenly lit up, and he changed his previous depressed look and started jumping up and down between the branches of the tree.
