Zhang Jun didn't give up easily, because there was suddenly one more thing in his hand, which was a sharp branch, about two meters long, as thick as a human arm, which he had chopped off and left on the ground before, and he struggled to throw the branch in his claws and threw it towards the monster's claws.

Soon, Zhang Jun saw that the branch shot under the monster's wings and hit its feet, and then saw that the monster's claws suddenly shook, and the bald head that it grabbed immediately fell down.

Looking down at a blood hole in the paws of his feet, and the blood dripping down, the monster immediately let out a terrible hiss, it never thought that Zhang Jun could shoot out a certain part of his body, it was really incredible, so that it could eat chicken instead of a handful of rice.

With great indignation, the monster glanced back at Zhang Jun with blood-red eyes, and then flapped its wings and flew out towards the night sky without hesitation, obviously it had lost part of its combat effectiveness and needed to go back to recuperate its injuries, and it may not survive the infection of the wound and survive.

Due to the darkness of the night sky, Zhang Jun did not see the full picture of the monster clearly, but the general outline was very clear, and he found that the monster looked like an enlarged version of the pterosaur, but the size of the pterosaur in this period was far from so huge.

Zhang Jun didn't know how these creatures that were not mentioned in books and science and education films suddenly appeared in this era, which had subverted the scope of knowledge he once mastered, and he wondered if these prehistoric creatures had existed, but later generations of scientists did not find their fossils.

But Zhang Jun thought about it carefully, according to Darwin's theory of evolution, animal evolution requires a long historical process to complete, a giant beast that can fly in the sky must have evolved from a small flying dragon, and the intermediate process must exist, so according to archaeological findings, it seems impossible to appear this kind of giant flying monster in this era, because this evolution process seems too fast, and it is obviously not in line with the laws of science to evolve such a huge volume monster directly from the pterosaur, unless Darwin's theory of evolution itself is problematic.

Just now, the bald head fell on the grass and was almost blinded, but fortunately, the height of the monster dropped it was only a few meters, and there was a layer of dead leaves on the ground, which could be used as a buffer, so the bald head was not injured when it fell, but the brain felt a little dizzy.

Big Al and Little Al immediately rushed through a gap and came to the bald man's side, looking at their good buddy to see if it was hurt, and Big Al stretched out his paw and rubbed it on the bald man's back a few times to show his condolences.

The bald head then shook again, walked to Zhang Jun's side not far away, and then rubbed Zhang Jun's belly with his head, and let out a screaming sound in his mouth, expressing infinite gratitude to Zhang Jun.

"Bald, I brought you to this dangerous area, and I will protect you well." Zhang Jun immediately stretched out his paw to pat his bald head, and let out a few strange tones with concern.

Although the bald head can't understand Zhang Jun's strange language, but it understands the leader's intentions very well, the bald head has regarded the leader as his close big brother, every time as long as he is by his brother's side, it feels full of security, this time, its choice is right again, the leader's brother really lived up to expectations, with extraordinary ability, drove away the invaders, and saved himself.

Then several small dragons gathered together and hid in a corner, not daring to come out again, while several other big male dragons protected them in a branch.

Zhang Jun had just realized the great benefits of hand tools, so he thought of getting one or two of these tools in hand. Trees and rocks and animal bones can be used to make weapons, but stones are too easy to break, and only weapons made of wood and bones are relatively durable.

Then Zhang Jun began to walk around the dragon's nest again, looking for a suitable wooden pole, and after looking for a long time, he found a straight branch, about three meters long, as thick as a human forearm, which was more suitable for making a spear.

Then Zhang Jun found a sharp stone and began to use it to sharpen the head of the branch, sharpening it like a pencil, slowly cutting out a pointed end, Zhang Jing's hand claws are not flexible, relatively hard, so the posture of using hand tools is also clumsy, but long-term cultivation of the Yi Jin Sutra, and deliberately exercise the flexibility of the fingers, so that he has basically been able to bend the claws to the point that other Allosaurus can't do.

Zhang Jun is now like a dinosaur who has practiced yoga, the flexibility of the body bones is much stronger than that of ordinary dinosaurs, and the flexibility of his fingers has also been greatly improved.
