"Run!" Heipi raised an arm, then suddenly pulled the arm down, and let out a short whistle from his mouth, the voice was rapid and short, this was the method of giving orders that Zhang Jun had taught him.

Then I saw a group of flying dragons on the grass, and began to run forward frantically, and there was a row of javelins in a clearing in front of them, and the javelins were in the same straight line, and whoever got his javelin first would be considered a victory.

As soon as the voice fell, I saw that several flying dragons had already jumped high, their bounce power was amazing, they could jump out a few meters at a time, and then I saw them running as they jumped, and soon ran towards the javelin two hundred meters away.

At first, he couldn't tell the winner, but by the end of the line, the mountain was significantly faster than the other flying dragons, and he finally won, and then returned to the place with a grin.

Then the multicolored wyvern continued to race, after Fei Ge ordered, they all ran in one direction, and finally needed to reach the top of a big tree, this time there was no suspense, Nanxiong in the prime of life won the victory, throwing the other multicolored wyverns dozens of meters away.

At this time, there was no concept of sports competition, and Zhang Jun made this matter out in advance in order to improve the physical fitness of the dragon group, so that they usually pay attention to the exercise of these skills.

Each competition ended quickly, and in addition to Dashan and Nanxiong, several outstanding flying dragons and flying dragons were arranged by Zhang Jun to be small leaders and let them become the leaders of the hunt.

When the game was over, the dragons were waiting for Zhang Jun to order them to set off and go hunting by the river, but this time Zhang Jun was not in a hurry to let them go, and he suddenly took out a strange object from under a turf.

It was a huge bow and arrow, the string was two meters long, this is a big bow and arrow that only Allosaurus would use, it was specially made by Zhang Jun for Allosaurus, and he also prepared several small bows and arrows, suitable for the use of the Flying Dragon, and the string of the bow and arrow prepared for the Flying Dragon was only one meter long.

The arrows are made of wood and bamboo, the head is sharpened, and the tail is also tied with bird feathers, although Zhang Jun has not made a bow and arrow by himself, but the memory of his previous life allowed him to quickly master the production skills, and the bow and arrow can be made quite well.

When Zhang Jun stepped forward with a huge bow and arrow, most of the dinosaurs and flying dragons were very surprised, they had never seen this kind of tool before, its structure looked complicated, they didn't know how to use it, they tilted their heads and began to think.

"What is the thing that the ancestral god is holding in his hand, it looks mysterious, what is it for?" The Flying Dragon and the Colorful Flying Dragon, which I had never seen, were very surprised, and when I was competing before, Zhang Jun had never taken out this thing, which felt very strange.

This kind of bow and arrow has only been seen by a few ancestors, Zhang Jun has made bows and arrows with similar materials, and several ancestors have also learned to use them, but because of their huge size, they are invincible in the new generation, so this kind of bow and arrow that was used for a period of time in the Jurassic was not widely used by the dragons after that.

However, in the Jurassic plants, there is no bamboo such a strong species, so the bow and arrow made at that time can only shoot a distance of more than ten meters, and the power is not great, this distance Allosaurus only needs a jump to do, and the bow and arrow at that time did not have metal arrows, the strength is weak, for the huge prey, it is tantamount to scratching the boot, so the bow and arrow was not popularized by the dragon group in the Jurassic.

Nowadays, the dragon group is no longer the only overlord on land, the reduction in size makes them dependent on bows and arrows, and becomes an option when fighting, of course, melee combat is still the mainstream of the wild world, bows and arrows can only play an auxiliary role, and today's bow and arrow production materials are much better than in ancient times, in addition to bamboo, you can also use mulberry and elm to make bows, their bullet surnames are not bad, bowstrings can be made of cowhide, cow tendons and other materials, these materials are also very easy to take, so bows and arrows are suitable for mass production.

"Bow and arrow, the leader has a bow and arrow in his hand, I haven't seen this thing in a long time, we haven't used it for a long time." The bald man immediately saw it, pointed to the bow and arrow in Zhang Jun's hand, and said to the black skin beside him.

Heipi nodded and said, "I knew that there were so many monsters in Central Asia, and we should have made a batch of bows and arrows before we set off to deal with aliens like Sword and Tiger." ”

Da Al still had doubts about the bow and arrow in Zhang Jun's hand, and he continued: "We have used this thing before, I don't think it is very useful, the impact of the arrows it shoots is too weak, and the animals with slightly thicker skin can't pierce at all, far less powerful than holding spears and sharp claws, I don't know why the leader suddenly remembered it?" ”

Several people have their own opinions, some think that Zhang Jun takes out a bow and arrow to display, it must have a use, and some have great doubts about it, but they don't know that the production materials used by Zhang Jun have changed a lot.

At this time, the bow and arrow, the shooting distance and the ejection power have long been incomparable, not comparable to those of the year, and the enemies they faced at this time are not comparable to the earthquake dragon, the Tyrannosaurus rex and other huge dragons, and the use of bows and arrows to deal with creatures like sword tigers can play a certain killing role.

Zhang Jun took a few steps to the center of the grass with a hint of mystery, and then he waved his hand to signal the other dinosaurs to withdraw from the sides for a distance, and then two leaping dragons carried a large round wooden plank to the front, this is a target made by Zhang Jun, this target is very thick, full of twenty centimeters thick, the diameter is also more than one meter, made of relatively hard sandalwood.

The arrow in Zhang Jun's hand is made of bamboo, this time only for demonstration, if it can be shot into sandalwood or other harder wood, to a certain depth, it is enough to prove that it can pierce the thick skin of animals and shoot into their vital parts.

Zhang Jun didn't speak, he wanted to let the dragons see the effect of his archery more intuitively, and then introduce them to the meaning of bows and arrows, and then it would be much easier for them to understand.

When the two flying dragons were fifty meters away and set up the target with a bracket, Zhang Jun began to stand in place, posed, slowly pulled the bowstring in his hand, aimed the arrow at the bull's-eye, and prepared to shoot.

"What is this going to do, Chief, his posture is strange?" The leaping dragons on both sides began to chatter, and they wanted to see what kind of medicine was sold in the ancestral god's gourd.

All the Flying Dragons and Flying Dragons focused their attention on Zhang Jun's hand, Zhang Jun's arrow was very long, more than one meter and a half, thinner than the wooden spear they held in their hands, and the shape was different, but they could only guess the purpose, probably used as a weapon.

Zhang Jun held his breath and concentrated, aimed at the target fifty meters away, and slowly released the string in his hand, and then saw that the arrow in his hand immediately broke away from the bow and arrow, flew out, and flew towards the target in front of him.

In the surprised eyes of everyone, the arrow flew out at a very fast speed, which was many times faster than the projection spear they usually use, many dinosaurs did not see how the arrow was shot, only to see it shot into the distance at once, and then after a light sound, the arrow of the arrow pierced directly into the wooden target, but because the arrow of this arrow is not made of metal, it did not achieve the effect of entering the wood for three points, but it was just inserted into the target, about three centimeters or so, but it was also firmly inserted into it, Didn't fall off.

Zhang Jun's shooting skills are not so good, and the materials he chooses for bows and arrows are not the best, if he uses bone arrows, or other harder materials, which are harder than wood, the effect will be better, and these will make some improvements in the materials in the future.

Although the performance of this arrow was not satisfactory, he made these dragon descendants feel the unprecedented technological progress and revolution, this is the first time they have seen this creative and potential weapon, its speed, accuracy, and lethality are more powerful than the spear projected, and the long-range attack is absolutely incomparable.
