Still alive 200 million years ago

The area under Xu Dong is a mountainous forest area with lush trees, which is very unfavorable for hunting red-scaled flying dragons. It is difficult for large flying units with a wingspan of three meters to move in the woods.

But this group of red-scaled flying dragons has grown to more than fifty. The reason is that there is a big river at the foot of the mountain. As long as they fly along the river once a day, they can always find prey to fill their stomachs.

Xu Dong now wants to clean up the large creatures on both sides of the river along their hunting routes, dyeing the entire river red.

It was morning, not yet the hottest time, and not many dinosaurs came to drink water. However, Yimen Caiyunlong dragged his family over to drink water.

Yimen Caiyunosaurus belongs to the sauropod suborder Plateosaurus, with a body length of five meters and its weight? ? , looks almost the same as Plateosaurus more than 10 million years ago.

There are five of them in the family, two big and three small. The adult Caiyunlong is more vigilant. After looking around for no danger, he brought the little dragon to the shore.

When they arrived at the shore, they were not allowed to drink water. Instead, they carefully observed the movement of the water. The little dragons were more lively and loved to play and play. From time to time, they would use their tails to stir up stones on the ground, sending them flying everywhere.

Xu Dong originally didn't want to attack these five-meter-long vegetarian dragons. If he wanted to do it, he would attack large predators. He was not happy with soft persimmons like vegetarian dragons.

But when he saw a piece of wood floating on the water, Xu Dong changed his mind. The previous three Chinese dragons had not been defeated, and now he would try the strength of this group of second-generation crocodiles who had inherited the legacy of the previous dynasty.

Sure enough, before long, the wood on the water eagerly pounced on Yimen Caiyunlong who was drinking water.

The crocodile's target was not the three little dragons, which were only over one meter in size. They were not big enough for it to fit between its teeth. Instead, its target was one of the adult Caiyunosaurus.

Logically speaking, the Angled Scale Crocodile Cocassoia was not that big at this time. After all, its ancestor was a pseudocrocodile the size of a dog. It seemed difficult to grow into a seven-meter giant beast after more than 10 million years.

Even the cheating dinosaurs took it one step at a time, starting from less than one meter and slowly climbing in size. As of now, the largest predator is only 7 meters, and the vegetarian dragon is only about ten meters. Of course, we must exclude people like Sauropods are special species with super-giant cells.

But regardless of whether it was a crocodile or a plant dragon, Xu Dong was ready to take advantage of it.

Among the more than 40 red-scaled flying dragons collected by Xu Dong, there are only about ten adults, which is smaller than the Xu Dong group.

Because of the last turf war, nearly half of the adult flying dragons were unwilling to follow Xu Dong and chose to leave. Most of the remaining ones were female dragons and young dragons.

In order to avoid losses this time, he asked the local flying dragons to watch from the sky and learn how they carried out swarm attacks.

Flying to a high altitude, Xu Dong predicted the position and quickly flew down. The dozen or so adult red-scaled flying dragons behind him also followed him downwards.

After several days of experiments, Xu Dong adjusted the tactics of swarming dives. Because the claws of the red-scaled flying dragon are different from those of later generations of birds. The claws of birds are sharp and good at piercing, while the claws of the red-scaled flying dragon are long and flat and good at chopping. Therefore, It needs to be adjusted to an action more suitable for the Red Scale Flying Dragon's attacks.

The crocodile in the river had successfully hunted it. It dragged the 5-meter-long Caiyunlong into the river and started a death roll in the shallow water, splashing water everywhere.

Xu Dong did not expect that the crocodile would be attacked first before he could attack him. Although the speed had slowed down at this time, the water droplets hitting his body were still very painful.

But soon the pain turned to the crocodile.

Xu Dong slowed down and drew a beautiful arc. When he passed the crocodile's head, his claws stretched out, and with the help of inertia, he was able to make a large gash on the prey.

This move is very effective against dinosaurs, and its lethality is astonishing. Dinosaurs often cannot withstand a few blows before being cut into combs, and die in humiliation on the ground, with no room for resistance.

However, it was not easy to use against a crocodile with subcutaneous bone. Xu Dong felt as if his claws were scraping against an iron block, making a harsh scream and almost breaking Xu Dong's claws.

It seems that we will have to use piercing method to deal with them in the future.

Of course, the crocodile didn't feel well either. The death roll hurt it even more, as if it was rolling its body to face its claws.

Although there is a defense of subcutaneous bone formation, the pain is real, and the skin will still be scratched. As long as it bleeds, the red scale flying dragon's toxin can be injected into the crocodile's body.

The poison of one red-scaled flying dragon is nothing, but what about ten of them?

The following flying dragons perfectly copied the trajectory drawn by Xu Dong, and each one passed through the crocodile.

A dozen claws came one after another, causing the big crocodile to bleed all over its body. The death roll caused the blood in the body to flow rapidly throughout the body. Finally, it couldn't bear it anymore.

The bleeding all over the body couldn't be stopped, and all kinds of hallucinations appeared in the head. It staggered onto the body of Caiyunlong, and under the attempted attack of the local dragon, it fought with the freshly killed prey under it. died together.

Tasting crocodile meat again, it was still so unpalatable that Xu Dong didn't want to eat it after a few bites. The size difference between this guy and him was only twice that of him. He was given less source of essence and didn't need to think about the components.

[Acquired component: Belly skin of aquatic crocodile]

Huh? What species is this? Never heard of it.

In a flash, Xu Dong thought of the value of this component. The belly skin of a crocodile would definitely be priceless in future generations. It could easily be sold for hundreds of thousands when made into bags, belts, and leather shoes.

But for the current Xu Dong, although the crocodile belly skin has good defense, it is not flexible enough and is too rigid, which is not conducive to him changing directions and turning in the air. His original equipment is more suitable for air operations.

The meat of one crocodile is definitely not enough for more than seventy red-scale flying dragons, even if the dead Caiyun dragon is included, it is far from enough.

Fortunately, the local dragons who have tried the air attack tactic can also become a viable force in hunting. They do not need to be limited to one creature, and multiple dragons can attack together.

At noon, the sun was shining brightly, and it was time for the creatures to gather together to drink water. Countless creatures, large and small, came to the river to drink water, even the overlord Sandie Chinese Dragon was no exception.

After this silly dragon with a double crown drank water to quench his thirst, he naturally turned his attention to the vegetarian dragon drinking water in the distance. Looking at this moving mountain of meat, tears flowed from his mouth unsatisfactorily. come out.

While it was looking around for suitable prey, the whistling wind sounded in the sky. The idiot didn't even have time to raise his head to see what it was, and his body was scratched with blood marks that were deep enough to see the bones.

The three-tiered Chinese dragon fell to the ground in pain. The pain and toxins made its whole body weak. It reluctantly opened its amber dragon eyes and saw a group of red figures passing by.

The place it passed was like a wheat field driven through by a lawn mower, with corpses lying all over the place.
