Throughout the history of human development, it seems to be a long time, with a short period of millions of years.

Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, and then the Cretaceous in which Linye is currently located. And these epochs add up to the Paleozoic and Mesozoic epochs of the earth, not including the Archean and Cenozoic eras.

Each epoch lasts for hundreds of millions of years, and tens of millions of years, and the Cambrian, the first major development of the biological world, is 570 million years ago.

One percent of 500 million years is five million, and the survival time of human beings, when converted into the progress of the entire history of the biological world, is less than 1%, which is just a drop in the ocean in the long river of time.

Why did not any higher intelligent beings appear in the long river for 99% of the time before this?

At the end of the Triassic, mammals appeared, and their brain capacity was no different from that of the present world, but they were suppressed by the dinosaurs for hundreds of millions of years.

Fate, or is it a coincidence?

——————————

It's already afternoon, and the icy breeze in the shallow water brings a touch of coolness to the dry earth.

The hairy rat's intelligence exceeded Lin Ye's expectations, and with the hard work of the hairy rat, Lin Ye's course progress was also much easier, starting with simple numbers. If there is something he doesn't understand, Lin Ye will use body language to supplement the explanation.

When teaching the hairy mouse to learn Chinese characters, Lin Ye's eyes swept and found that a black mole appeared on the hairy mouse's abdomen. Under Lin Ye's keen eyesight, this black mole expanded in just five minutes. And the hairy rat himself doesn't seem to know at all.

Lin Ye narrowed his eyes, he activated the flame feather cloak, ordered the hairy mouse not to move, and then the black flames immediately pounced on the black mole.

The hairy rat squeaked, its stomach burned with flames, its fur rolled up, and even the smell of burnt.

Lin Ye's method was very effective, the black flame covered the black mole, and in less than a second, the black mole was burned and destroyed by the flames. Lin Ye vaguely heard a scream from the soul, which was the black mole that came out before it was burned out.

The symptoms of a mutated caveman also appeared on the body of the hairy rat!

After the lesson, the hairy mouse felt that he had grown a lot, and he looked up, his eyes full of thirst for knowledge. And the mole on its body did not recur.

The pilot was a success, and Lin Ye thought that he could call the egg-stealing dragons and the red-backed to learn Chinese characters.

But it's a little late today, and although the hairy rat is diligent and studious, his spirit is also sluggish.

After instructing the hairy rat to take care of the rice fields, Lin Ye set off alone and came to the Qinggu District, which was blocked by the canyon, where there were some stupid Qingdao dragons, and there was a path on the opposite side of the canyon that was the only access to the Qinggu District except for the underground waterway.

Jumping on a stupid Qingdao dragon, Lin Ye tried to communicate with the Qingdao dragon. They just chewed on the blades of grass for themselves, completely ignoring Lin Ye.

Sure enough, it's not smart enough. These Qingdao dragons are like a group of natives, and Lin Ye tries to civilize them. He stood in front of the Qingdao dragon and opened his mouth to sing, and after finding that it didn't work, he danced in front of the Qingdao dragon, which was completely useless.

No matter how eye-catching Lin Ye made in front of Qingdao Dragon. Qingdao Long also has an indifferent attitude, and will only take care of Lin Ye when it is related to his own safety.

Lin Ye was so angry that he kicked this behemoth, and the Qingdao dragon immediately let out a sad roar, stepped out of all fours and fled.

The reaction after the beating was quite quick. Lin Ye was speechless, it seemed that this group of Qingdao dragons was completely unteachable.

As the saying goes, curiosity kills cats. But if you don't have the spirit of exploration, you will end up being swallowed up by the dangers that spread from the outside world.

After the ancient crocodile was killed, there seemed to be no more creatures that threatened them. These Qingdao dragons live very freely. But this is an illusion.

On the edge of the only road leading to Aoya District, the river that nurtures silver-scaled fish spreads all the way, and it is unknown where it will end. Lin Ye found three or two vague footprints on the side of the road, which were twice as large as the footprints left by the Qingdao dragon. In the form of three petals, this footprint is only a wanderer around the entrance of the canyon, and does not enter the green valley.

The inside of the footprints is deeply embedded in the earth and appears to have sharp claws, a large carnivorous dinosaur. This carnivorous dinosaur is now in the west of Qingdao District, but also in the southwest of the Cordyceps Field, directly south of the area where the pterosaur that was killed by Lin Ye lived.

It's still unknown. Since the carnivorous dinosaur didn't come to provoke Lin Ye, Lin Ye naturally wouldn't attack it with any interest in himself.

However, it is still necessary to do a good job of prevention, thinking of the previous attack of the pterodactyl, you can't make this kind of mistake again.

Lin Ye followed the river to the exit of the canyon in Qingdao District and looked into the distance.

It's a green grassland, with undulating butterflies fluttering and sucking the nectar of the colorful flowers nearby. The change of seasons doesn't seem to have a very serious effect on them.

Huge fern-leaved forests are scattered across the grasslands like pine trees, and at the foot of these fern-leaf forests hide small brown-fur animals. They shivered, as if they were hiding from predators.

As soon as Lin Ye looked up, he saw a group of beautiful jawed dragons two heads larger than him in the distance, and they passed through a ground ravine in pairs. The ravine was formed by an earthquake a long time ago and split three kilometers long from north to south.

These jawed dragons, not sparing any place to prey, searched for fern trees, and in less than a moment dragged out a small animal and swarmed up.

Is it a social creature?" Lin Ye muttered to himself in confusion. He remembered the beautiful jawed dragon that had dominated the shallow waters (former swamps) before, and had always fought alone, without companions. Now it looks like this jaw-dwelling dragon should have come from here.

As for how it got to the shallow waters, it seems that it will have to be carefully figured out.

The creature that was brutally torn apart let out a scream, its limbs were torn by the jaw-dwarn as if it had been torn apart by five horses, its limbs were broken, and flesh and blood flew sideways, and the mutilated dragons raised their heads proudly and screamed in the sky. But in the next second, their chirps were rapid, and they immediately abandoned the small animals that had been dismembered and ran away quickly.

There was silence for a while, and the beautiful jaw dragon disappeared out of Lin Ye's sight in the blink of an eye. Lin Ye held his breath as he saw the head of a giant dinosaur peeking out of the high slope of the grassland. The giant dinosaur didn't look like it was going to go over the high slopes, but to the south.

It has a hideous scar on its head and dry skin. The mouth opened and closed slightly, and saliva flowed, and if it was opened, it was enough to swallow a whole Qingdao dragon.

With each step, the earth shook violently, and the giant dinosaur turned its back to Lin Ye, who was thousands of meters away, its nose sniffed, as if it smelled something, and ran quickly towards the west, and disappeared from Lin Ye's sight.
