In the midst of Yun Lei's sigh, a group of dinosaurs about two meters long, about one meter tall, and weighing about dozens of kilograms, which looked similar to humans and had feathers all over their bodies, walked out of the depths of this forest.

According to the research and classification of dinosaurs unearthed by scientists according to archaeology, dinosaurs of the family Traumatodontosauridae are group-type, small to medium-sized, theropod dinosaurs.

Because it is related to Archaeopteryx and some other dinosaurs, which are probably the ancestors of birds, it is light and does not look like a dinosaur, but like an ostrich with a strange shape and coat color.

And proof of this is the arm of the odontosaurus. The pair of forelimbs of this odontosaurus are more like a pair of wings than the forelimbs of a dinosaur. The arms of this odontosaurus were extremely flexible, not only could they be folded back like birds, but also had thumbs on the hands that could make relative movements.

At the same time, there are slender hairy feathers on this arm, similar to the roosters of later generations.

It seems to be a mixture of chicken feet and chicken wings, which is quite peculiar. But it looks much weaker than a human arm.

The hind limbs, that is, the feet, of these wounded dragons that came out of the forest were extremely powerful. The second toe on both feet has large, curved claws that retract, similar to the sickle-like claws of the Chironidae family.

If you are kicked in such a leg, you will definitely be seriously injured.

The number of this group of odontosaurs was about 100 or ten. After coming out of this fern forest, he surrounded Yunlei and Rao Ya, but he did not attack rashly. Instead, he looked at Yun Lei and Rao Ya with a probe in his head.

When their eyes came into contact with Yun Lei, Yun Lei and Rao Ya could actually see the feeling of agility and wisdom in their eyes!

The eyes of the odontosaurus were quite large, similar to those of humans, and they were all oriented forward. So, the vision of this tooth-wounded dragon is three-dimensional, and it is very good. Far better than the existence of 2.0 vision in humans. Yun Lei was very sure that these tooth-wounded dragons could see every detail of him and Rao Ya in detail.

According to scientists' research on Odontosaurus, this carnivorous omnivorous dinosaur will not have color vision because of its nocturnal habits. However, the ability to recognize faint light is far better than that of humans!

Humans, on the other hand, have evolved the ability to see in color because their ancestral primates ate fruits in the forest.

If visually, the Wounded Tooth Dragon and humans are still good at each other, then, in terms of hearing, the Wounded Tooth Dragon can completely explode humans. The ears of the odontosaurus shook off the eight streets of other types of dinosaurs. In its body structure, there is an unusually large space in the middle ear, so it can hear with extreme precision.

Moreover, because the middle ear space of the odontosaurus is close to the eardrum, the odontosaurus can easily hear low-frequency sounds.

In addition, because the position of the ears is not symmetrical, the ears on both sides of the skull are located at different heights, so the sound will be more three-dimensional. Just like the owls of the Hereafter. At night, you can use your hearing to accurately locate the location of your prey or enemy.

Yun Lei looked at the group of tooth-wounded dragons who were curiously looking at him and Rao Ya, laughed, and said, "Hello!"

Rao Ya rolled her eyes, feeling that Yun Lei was really boring, and she actually tried to communicate with this group of tooth-hurting dragons in human language.

What surprised Rao Ya was that after Yun Lei said the "hello", the attitude of the one hundred and ten toothed dragons surrounding them seemed to ease up a bit.

Rao Ya was very surprised, and asked Yun Lei, "How can they understand what you are saying?"

Yun Lei said: "The communication between living beings depends not only on language, but also on the posture, tone, emotion, and other details that are revealed. What's more, I'm pretty sure that there are more advanced beings among these Toothless Dragons?"

"A more advanced being, a Tyrannosaurus rex?"

"What is the strength of the body compared to wisdom? I am not talking about Tyrannosaurus rex, but the legendary existence - dinosaurus!"

Rao Ya was a little surprised: "Terrible, you mean...... That's what you're talking about, primitive intelligent life and primitive civilization that are possible on the island?"

Yun Lei nodded, remained silent, and quietly looked at the group of tooth-wounded dragons surrounding them. He didn't make any temptations, and he didn't take the initiative to attack! Anyway, these tooth-wounded dragons couldn't hurt him at all.

Half an hour later, deep in the jungle, a bird's cry sounded!

Once intelligent life has evolved to a certain extent, it will become cherished its own life, not that it does not have the determination to fight to the death, but that it will not seek death for some meaningless things.

Desperate and senseless attacks are simply a waste of life.

And from the path that these toothless dragons got out of, more than a dozen unusual toothless dragons appeared from this path.

It's just that the posture of these tooth-wounded dragons is already different from these similar people next to them. The heads of these odontosaurs are no longer long strips. Instead, it becomes round. It's obvious. The brain volume of these odontosaurs has increased. It's just that the mouth full of sharp teeth is still there.

Moreover, these odontosaurs are no longer the same as they used to be, leaning forward and being longer than they were. The upper bodies of these odontosaurs are visibly erect. As the upper body straightens up, the balance changes, and the tail behind these odontodontosaurs becomes significantly shorter.

What surprised Yun Lei and Rao Ya the most was that the forearms of these tooth-wounded dragons had become stronger and more slender than those of their kind. Although the hands are still in the shape of chicken paws. The nails are extremely tough, but they each hold a wooden spear in their hands!

Of course, there is no spearhead made of stone tools on the spear. Only when a branch breaks, it naturally breaks off sharply. Only one of the head of the toothed dragon carries a weapon similar to a bow.

These odontosaurs, obviously, have broken away from the category of beasts and ordinary dinosaurs, learned to use tools, and become a member of intelligent life! And they are a completely different kind of intelligent life from humans.

Rao Ya almost dropped her jaw in shock, and sighed: "This, how is this possible? These people are all dinosaurs! Dinosaurs! Dinosaurs......

And these dozen tooth-wounded dragons, after carefully looking at and observing Yun Lei and Rao Ya, the tooth-wounded dragon dinosaur with a bow in one hand and a spear in the other, screamed at this cloud thunder!

The voice was stern, and it seemed to ask—who are you? What are you doing here?
