Zhang Jun was squinting his eyes and looking up at the bright moon and looking down at his hometown, but he was suddenly disturbed by a violent cry, he looked up and saw that on the branches dozens of meters away, there were two small animals fighting fiercely, tearing each other apart. Although the light was dim and he couldn't see clearly, judging by the sound and general size, it should be a ornithosaurus and a color-headed beast that suddenly broke out.

The two animals were about the same number in the jungle, so they often fought, and this time they began to bite violently for the nest of a bird in a tree. Ornithophosaurus and Colorhead's teeth are very sharp, Ornithophobia's claws are a little more powerful, and Ornithophosaurus has a pair of small wings that can glide, and can retreat at any time if it can't win, but Colorhead's kung fu climbing trees is first-class, very flexible, and it beats between branches is also very neat, and the two seem to be evenly matched.

Zhang Jun was bored, Suo began to carefully observe how they dealt with their opponents, watching them quickly claw and bite, and soon, the bird-loving dragon and the color-headed beast were both defeated, and finally the bird-loving dragon was slightly inferior, unable to hold back and turned around and ran away, the color-headed beast was also injured, and several parts of its body were bleeding.

After winning the battle, the beast did not rush to reach the bird's nest at the top of the tree, but suddenly climbed down the trunk from the branch to the grass, and then kicked the ground on all fours, and ran to a dirt slope near the dragon's nest, and then crouched there without moving.

Zhang Jun felt a little strange, he didn't know what the Color-headed Beast was doing, so he suddenly stood up, tiptoed towards the location of the Color-headed Beast, and when he was ten meters away, he began to peep at the Color-headed Beast.

At this time, the color-headed beast was lying on the ground, biting down a plant with its mouth, it was a kind of green grass, which grew like a sword, and was more than a foot high and about three inches wide.

The Colorhead kept biting off a small piece of the sword grass, then chewed vigorously in its mouth for a while, and then spit it out on its own wound along with its saliva, and licked the wound with its tongue from time to time.

"Nima, could it be that this color-headed beast knows how to heal itself and heals itself?" Zhang Jun was a little surprised, and suddenly froze in place.

Zhang Jun suspected that this kind of color-headed beast was using sword grass to heal its wounds, otherwise this kind of action would not have appeared, and he was amazed that this mammal could have such a clever method, which was a huge leap for humans who might just be pediatrics, but for savage beasts.

The color-headed beast tossed around in this area for a while before leaving, more than a dozen sword grasses were used up by it, and only the roots remained, Zhang Jun stared at the color-headed beast carefully, to see where its nest was, and he saw that the color-headed beast returned to a small cave dozens of meters away.

The wound of this color-headed beast is deep, and you can see the white bones inside, if the wound is allowed to become infected, it is likely to die, Zhang Jun wants to see if this guy can recover.

Early the next morning, Zhang Jun began to follow the color-headed beast, and then he found that it did not come out of the hole for several days, and it did not come out of the hole until the fifth day, and when it came out, Zhang Jun saw that the deepest wound on its leg had healed, and there was no sign of infection and swelling.

"It seems that this sword grass really has a healing effect, and the color-headed beast really deserves to be a clever mammal ancestor!" Zhang Jun's heart immediately amazed.

Zhang Jun immediately began to study the effect of this sword grass, the sword grass is a special variety on this giant island, which has not been found in his previous territory, and there is a medicinal herb that can treat external injuries, which is the biggest blessing for the dragons who have been fighting for a long time and are easily injured.

In terms of using tools, Zhang Jun's expectations for the little dragons are too high, their positive surnames are far less high than they imagined, many little dragons are just playing, and it is still very difficult for them to have the idea of killing animals with tools.

But Zhang Jun has seen monkey tricks, many little monkeys can imitate human movements, such as smoking, drinking, somersaults, and can also learn to ride bicycles and unicycles, etc., these are the skills that animal trainers have long trained to teach animals, although these animals are just to get food, and do these actions, they do not understand the essential meaning of the actions, but after all, they can be learned. So Zhang Jun was not discouraged, he decided to slowly make a little more effort.

Regarding the necessary surname for using tools, Zhang Jun also thought that although Allosaurus had sharp teeth and claws, which was more convenient than killing prey with a spear, the prey they faced was usually huge guys, and many Allosaurus would be injured during the fight.

Imagine if Allosaurus is facing the Seismosaurus, then the possibility of being injured is even greater, but at this time, if the Allosaurus uses a spear to shoot the Seismosaurus, it can launch an attack at a long distance, adding a new means of hunting, and the spear can also be used to deal with animals in the water, which is also a new option, of course, the natural claws and teeth of the Allosaurus, these conditions will also be used to the greatest extent.

If it weren't for the fact that Allosaurus was too stupid, Zhang Jun wouldn't mind teaching qigong to them, but this requires too much wisdom, and it is impossible for them to learn such a complex internal strength method, so there is no possibility of development in this area.

There have been no injuries to Allosaurus recently, so Zhang Jun can't find a suitable object to study the healing effect of Sword Grass, but he estimates that it will come in handy soon, because he is also observing the movements of another animal these days, that is, the evil dragon.

Zhang Jun found that in the past two days, there have been evil dragons running over here, and it seems that they have sent spy dragons. These evil dragons have a very strong social surname, and all the evil dragons obey the orders of the leader, and the leader tells them to die, and they will not blink an eye, which Allosaurus can't do.

If one day Zhang Jun is defeated by a strong enemy, before dying, he estimates that most of the Allosaurus will leave him, and only a few Allosaurus will stay and fight side by side with him, this is the difference between the Allosaurus and the evil dragon, Zhang Jun admires the unity and bravery of the evil dragon society very much.

Because several evil dragons have frequently approached the dragon's nest these days, Zhang Jun has become very vigilant, and he also began to go to the jungle to observe the movements of the evil dragon, he has not found the evil dragon's nest within a few kilometers in the surrounding area in the past few days, so there is no direction for a while, but the appearance of several evil dragons has given Zhang Jun a chance.

Zhang Jun began to look for an opportunity, taking Bald and five other male dragons, to follow these evil dragons who ran to the vicinity of the dragon's den, to see where they would return to their nests, as long as they could find the dragon's lair, and then make the next decision.
