After about a month, the sun's altitude angle gradually decreases, and late autumn in the northern hemisphere begins to change to early winter. At the same time, the carbon dioxide content outside the earth's protective shield was also decreasing. As a result of the interaction, the area where Qiao Hua was located began to feel slightly chilly. Along with this change, the long hairs on the bodies of the fruit core and bean paste have gradually grown shiny. Qiao Hua's body didn't change much on the surface, but because he was a cold-blooded animal, his body temperature increased a lot as the outside temperature dropped. As for Crick, this big dog often shivered with cold in the beginning and clamored to use the space teleportation device to go to a warmer place every day. But later, Crick stopped making noises, and instead behaved calmly and contentedly every day. "Don't you feel cold anymore?" Qiao Hua asked. Creek lay on the ground and replied lazily: "My clothes can also activate the heating and cooling function. With the protective cover wrapped around my body, it is like a small heater now, and it is no longer cold." Qiao Hua couldn't help feeling a little helpless. Only then did he realize that it was troublesome for him to carry an intelligent creature around every day. Non-intelligent creatures like fruit cores and bean paste will never complain about changes in temperature, but generally adapt to the environment through their own adjustment mechanisms. "But Crick is different. Once he is dissatisfied with the surrounding living environment or the food he eats, this big dog will be picky. It seems that this alien pet was spoiled by Ada, so it couldn't bear any hardships. Fortunately, this big dog has now found a way to keep itself warm, otherwise we don¡¯t know how long it would have been. "Completely different from Crick's performance, Qiao Hua has been trying to break through his two abilities in this increasingly cold weather. After some hard work, the memory of this dwarf tyrannosaurus allowed it to copy something quickly. And never forget. ¡° Moreover, the two forelimbs finally stretched to a certain length through continuous breakthroughs, only a little shorter than the two hind limbs. Because the growth of the forelimbs causes the original body balance to be broken. Qiao Hua had to raise his upper body a little and shift his center of gravity back. And this approach. It is undoubtedly evolving towards walking upright! Qiao Hua suddenly felt that he seemed to be becoming more and more nondescript. Now his body has grown surprisingly large, and he seems to be becoming a humanoid creature. Although he had predicted such changes a long time ago, he still felt a little worried about the future direction of evolution. This feeling is like that of an insect that is about to emerge from its cocoon and become a butterfly, looking forward to and worrying about the fate of becoming a butterfly. ¡ As time went by, the vegetation began to turn yellow and wither, and the surrounding animals became less and less active. Qiao Hua sometimes had to run away for several miles. Only one or two large animals can be seen, and they are usually skinny and skinny. "Compared with this dwarf tyrannosaurus, Creek can gain a lot every time. Although Qiao Hua has never asked how the big dog captured so many prey, he can guess with a little thought that it must have used the high technology of their planet. Unlike the big dogs who are active every day, the bears and the little squirrels have become less and less active during this period, and sometimes even sleep for more than ten hours, except for eating and being in a daze. The big dog was baffled by this, but Qiao Hua knew it very well and thought, isn't this just hibernation? It¡¯s freezing cold. There was an animal carcass of about the same size in Crick's mouth. He ran quickly towards Qiao Hua. When stepping over a huge stone, the big dog's foot slipped and its center of gravity became unstable. There was a dog gnawing mud on the ground. "Woof!" The big dog staggered up from the ground, gasping for breath for a few times. Just as he was about to pick up the prey on the ground again, he suddenly noticed several streaks of light passing quickly across the sky. ¡°Swish, swish!¡± These lights disappeared almost in the blink of an eye, but it was difficult to escape from the eyes of this big dog. He suddenly had a bad premonition in his heart. "Did you see a few stars streaking across the sky just now?" Crick suddenly asked after bringing the prey to Qiao Hua. Qiao Hua scratched his two front paws at each other: "I didn't see it - it's daytime now, how could there be stars?" After saying this, Qiao Hua was stunned for a moment, and suddenly understood what the big dog really meant: "You mean, there was a spaceship passing by in the sky just now?" Only Ada's flashing eyes were extremelyA dazzling aircraft. Only then can it be captured by the naked eye during the day. However, judging from what Crick meant, the spaceship did not belong to Ada. And there's more than one. Qiao Hua couldn't help but said with some self-comfort: "Did you see it wrong? Maybe it was a meteorite falling from the sky." After saying this, the dwarf tyrannosaurus found that he was undoubtedly You are deceiving yourself. If it was really a meteorite falling from the sky. There will definitely be a very loud sound when it lands, and in such cold weather, the collision of hot and cold will definitely cause fog to appear in the sky. But now it seems like there is nothing. Just when Qiao Hua looked to the sky with doubt, a sight suddenly shocked him. A ray of silver-white light fell from the sky and rushed straight into the protective cover. Immediately, at the topmost position of this thin protective cover, white light collided with the protective cover, emitting an extremely terrifying light. Damn it! Qiao Hua only felt a blur in front of his eyes, and then heard a loud "boom", and the earth's protective shield was instantly made a big hole by the huge impact. And the spacecraft had already disappeared without a trace in the collision before it showed its appearance to the creatures on earth. "Why is it gone?" Qiao Hua came back to his senses and asked in surprise. The big dog looked very nervous at this time, and naturally thought of something. But it quickly diverted Qiao Hua's attention and said hurriedly: "Let's quickly check the damage to the earth's protective shield." In fact, before the big dog could say anything, Qiao Hua had already taken the turtle shell hat away from himself with his backhand. plucked it off his head. Since the forelimbs have grown to a certain extent, it becomes much easier to do these things. "Fortunately, I didn't suffer much damage." Qiao Hua said, fiddling with the holographic image panel in front of him. The protective cover has a certain self-healing ability. As long as the damaged area is not large, there is no problem. Crick naturally knew this truth, but what really confused and frightened him was another thing. (To be continued)
