After a month or so, the sun's altitude angle gradually decreases, and late autumn in the Northern Hemisphere begins to shift to early winter. At the same time, the carbon dioxide content outside the earth's protective cover is also decreasing, and under the interaction, the area where Qiao Hua is located begins to have a slight chill.

With this change, the long hairs on the pits and bean paste have gradually grown shiny. Qiao Hua's body did not change on the surface, but because he was an ectothermic animal, his body temperature increased a lot with the decrease in the outside temperature.

As for Crick, the big dog often shivered from the cold at first, and clamored every day to use the space teleporter to go to a warmer place. Later, however, Crick stopped arguing and remained at ease every day.

"Don't you feel cold?" Qiao Hua asked.

Creek lay on the ground and replied lazily: "My clothes can also turn on the heating and cooling function, and with the protective cover wrapped around my body, it is like a small stove now, and it is no longer cold." ”

Qiao Hua couldn't help but feel a little helpless. He realized that it was also a troublesome thing for him to carry a sapient creature around every day. Non-sapient creatures, such as fruit pits and bean paste, will never complain about changes in temperature, but generally adapt to the environment through their own regulatory mechanisms.

But Creek is different. Once there is something dissatisfied with the surrounding living environment or the food eaten, this big dog will be picky. It seems that this alien pet has been spoiled by Ada, so he can't suffer a little. Fortunately, now this big dog has found a way to keep himself warm, otherwise I don't know how long it will be tossed.

Completely different from Crick's cousin, Qiao Hua has been trying to break through his two abilities in this increasingly cold weather.

After a bit of effort, the dwarf tyrannosaurus's memory allowed it to quickly replicate something. And never forget it.

Moreover, the two forelimbs finally stretched to a certain length in the continuous breakthrough, which was only a little shorter than the two hind limbs. Because the growth of the forelimbs leads to the original balance of the body is broken. Qiao Hua had to raise his upper body a little to shift his center of gravity back.

And such a practice. It is undoubtedly evolving itself in the direction of walking upright!

Qiao Hua suddenly felt that he seemed to be becoming more and more nondescript. Now he's constantly getting bigger, and he seems to be on the way to becoming a humanoid. Although he had predicted such a change for a long time, he still felt a little worried about the future direction of evolution. This feeling is like a small insect that is facing a butterfly from its cocoon, and is worried about the fate of becoming a butterfly.

……

As time passed, the vegetation began to turn yellow and wither, and the animals around him became less and less active, and Qiao Hua sometimes had to run for miles. Only one or two large animals can be seen, and they are generally skinny and skinny.

Compared to this dwarf tyrannosaurus, Creek was able to reap a lot of rewards every time. Although Qiao Hua had never asked the big dog how he had caught so much prey, he could guess with a little use of his brain that he must have used the high technology of their planet.

Unlike big dogs, dogs, bears, and little squirrels become more and more inactive during this period of time, and even sometimes sleep for more than ten hours, except for eating and being in a daze.

The big dog was puzzled by this, but Qiao Hua was very clear about it, thinking that this was not hibernation?

Cold.

Crick had a carcass of an animal about his size in his mouth. ran quickly towards Qiao Hua. As he stepped over a huge rock, the big dog slipped and his center of gravity was unstable. A dog gnawed mud on the ground.

"Whew!"

The big dog staggered to his feet from the ground, gasping for air in his mouth. I just wanted to pick up the prey on the ground again, but suddenly found that several streamers in the sky were quickly passing by.

"Whoosh!"

The light was gone almost in the blink of an eye, but it was hard to escape from the big dog's eyes. He suddenly had a bad premonition in his heart.

"Did you see a few stars in the sky just now?" When Crick brought his prey to Qiao Hua's side, he suddenly asked.

Qiao Hua scratched his two front paws at each other: "I didn't see it - it's daytime, how can 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 flying machine that shone extremely brightly. to be able to be caught by the naked eye during the day. However, depending on Crick's meaning, the ship is not Ada's. And there's more than one.

Qiao Hua couldn't help but say with some self-comfort: "Could it be that you are mistaken?" Maybe it's a meteorite falling from the sky. ”

After this dwarf tyrannosaurus said this, it realized that it was undoubtedly deceiving itself. If it's really a meteorite falling from the sky. There will be a very loud sound when it lands, and in such a cold weather, the collision of hot and cold will definitely lead to fog in the sky. But now, it seems like nothing.

Just when Qiao Hua looked at the sky suspiciously, a sight suddenly shocked him.

A silvery-white light fell from the sky and rushed straight into the protective cover. Immediately, at the top of this thin protective cover, the white light collided with the protective cover, emitting an extremely terrifying light.

it!

Qiao Hua only felt a flower in front of him, and then heard a loud "boom", and the earth protection cover was instantly made a big hole by the huge impact. And before the spaceship could show itself in front of the creatures of Earth, it had already disappeared without a trace in the collision.

"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 hurriedly diverted Qiao Hua's attention and said hurriedly: "Let's quickly check the damage of the Earth Protective Cover." ”

In fact, without waiting for the big dog to say, Qiao Hua had already taken off the turtle shell hat from his head with his own backhand. Since the forelimbs have grown to a certain extent, it seems much easier to do these things.

"It's okay, I didn't get too hurt." Qiao Hua fiddled with the hologram 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 knew this, of course, but what really made it wonder and fear was something else. (To be continued)
