Still alive 200 million years ago

Raising dinosaurs in captivity may seem unthinkable and impractical, but it is not impossible.

Dinosaurs are animals too. Cows, horses, pigs and sheep can be kept in captivity, so why not dinosaurs?

This wilderness is a natural pasture. As long as the few roads that can leave are sealed, these dinosaurs will have to stay here obediently before the dry season comes.

Xu Dong's idea is to divide it into three steps. The first step is to make this wilderness into an island, and let the fence take shape. The dinosaurs inside cannot leave, and they will become pigs for the red-scaled flying dragons to be raised in captivity.

The second step is to hunt carnivores and omnivores, and kill all large, medium and small predators. Without the threat of predators, the growth rate of the vegetarian baby dragons will increase, and the number of vegetarian dragons in the dragon circle will increase. It will definitely increase dramatically.

The third step is to catch the big ones and let go the small ones. The red-scaled flying dragons only eat adult vegetarian dragons, so that the developing vegetarian dragons can grow up to become the next generation of pigs.

It still feels promising. Of course, Xu Dong still doesn't know what problems will be encountered in actual operation, but at least the prospects of this plan are worth looking forward to and it is worth his time to promote it.

Then let the island take shape first.

Xudong started looking at the confluence of the rivers in the east and followed the big river in the south all the way to the west to see if there was any low-lying place where he could cross the river.

Although this big river in the south is slightly narrower than the one in the north, it is still as wide as ten kilometers. Even the largest dinosaur of the Early Jurassic, the 18-meter-long Faris Patagonia, could not cross it. .

However, rivers always have shoals. Not long after the river went deep into the forest, Xu Dong saw a shallow river channel. The water flow was very slow, and you could even see small rocks protruding from the bottom of the river.

This shoal is located in a dense forest, and large vegetarian dinosaurs such as Lufengosaurus, Yunnanosaurus, and Kunmingosaurus could not enter the forest.

However, their baby dragons born in the forest can walk there, causing the loss of Xudong's assets. It is necessary to find a way to stop these small and medium-sized dinosaurs and baby dragons.

So what to do?

Looking at the dense trees around him, Xu Dong had an idea. He pushed down the trees to form an artificial embankment. Wouldn't that be able to stop the dragons from crossing the river?

With this location in mind, Xu Dong continued to fly westward along the Nanda River. After that, except for a river channel that was only a few hundred meters wide, there was no obvious crossing.

Flying out of the forest and into the mountains, what you see is the dangerous terrain and rugged rivers. If the dinosaurs could get out of this kind of terrain, Xu Dong would dare to take off their heads.

However, mountainous areas are not all dead ends. There are three or four naturally formed small mountain roads. Large dinosaurs will definitely not be able to pass through, but they are afraid that the young dragons will leave from here. The young dragons are little piglets in a pig pen, but they are very difficult to pass. valuable.

Xu Dong flew to the top of the mountain road and found that the rocks and soil were not very stable, which could be used.

When the time comes, let the red-scaled flying dragons work together to push down the rocks and create a man-made mudslide to block the road.

There are few trees in this mountainous area and the rocks are not stable. Several mountain roads can be blocked using this method.

After taking note of this place, Xu Dong continued to fly north, and soon flew over the river in the north of the wilderness.

This big river is different from the docile Southern River. The river surface is wide and the current is fast. The yellow river water is turbulent, roaring and roaring towards the east.

Such a big river is definitely a nightmare for dinosaurs.

Okay, now the main gaps have been identified, and these two can be solved artificially.

Xu Dong returned to the habitat to rest for a night, and the next day he flew to the southern woods with dozens of red-scaled flying dragons.

Arriving at this shoal, Xu Dong had already thought about what to do next.

The pine trees in this forest are very wide and hard. With the sharpness of the claws of the red-scaled flying dragon, the claws were useless after cutting down a few trees.

So Xu Dong, a pseudo-legend that transcends ordinary creatures, needs to be killed.

The tribe is responsible for pushing the felled trees in the designated direction, and the specific direction of dumping is planned in advance.

“Chop chop chop”

"Duoduoduo"

“Chop chop chop”

Xu Dong's claws kept chopping at the roots of the pine tree, making a sound similar to that of a woodpecker.

This pine tree grew very big and thick, with a diameter of four to five meters. In later generations, a tree so thick that even a chainsaw would be blunt.

But in this era, it is very common, at least it is surrounded by pine trees about the same size.

Xu Dong's body had been strengthened, and his claws were sharper than ordinary iron swords. Even so, the tree chopped down almost made his whole body twitch.

Even when he stopped after cutting, every part of his body was shaking involuntarily, the picture in front of him was shaking and trembling, his eyelids closed unconsciously, his head felt dizzy, and he wanted to sleep.

The reason why the woodpecker can keep pecking at trees without causing a concussion is because its tongue is very long and forms a shock-proof belt in the brain, so it is fine.

But Xu Dong didn't have this structure, so he could only rely on his strong physical fitness to resist.

As the red-scaled flying dragons continued to collide, the pine tree that had been cut in half finally fell down.

boom!

Pebbles were flying and water was splashing.

An unlucky red-scale flying dragon was hit by a stone. It screamed in pain, ran around and hit a big pine tree, and slid down.

Just wait and see

A large fallen pine tree lay across the river, successfully covering a large section of the river.

With its diameter of five meters, ordinary small and medium-sized creatures would definitely not be able to climb over it.

The low-lying shoal of the southern river is three hundred meters long, and a large pine tree can only block it for forty to fifty meters. At least six or seven more large trees must be cut down to completely block it.

This workload. . . Go ahead, what else can you do?

After all, Xu Dong is not an immortal species of 70 to 80 meters, and he has not loaded the super-giant components of sauropods, so he can only use this stupid method.

It took five days to finally build the pine tree embankment beside the shoal.

Maybe there are still some small dinosaurs that can climb trees that can climb out, but at least those sauropods, bigospondylsaurids, and true sauropod baby dragons will definitely not be able to get out.

As long as these little piggies can't get out, it doesn't matter if some free-range chickens escape.

The next step is to trigger mudslides and fill up those mountain roads. It would be great if it rained, and it would save the red-scaled flying dragon from hitting the rocks and cutting the dirt.

But unfortunately, it is not the rainy season now. The dry season has just come to an end, and it is difficult for the weather to change.

This is good news. If the dry season is coming, all the arrangements in Xudong will be in vain. The dry season will cause the two major rivers in the north and south to dry up.

Ferns in the wilderness will also become scarce, and dinosaurs will migrate across rivers to places with ample food to survive the dry season.

Come back here during the next rainy season to eat, reproduce, and recuperate.

Fortunately, the earth and rocks on these cliffs are relatively loose, and the earth and rocks are not solidly condensed. Xu Dong found some supporting positions.

Cutting on the joints of the earth and rocks on these mountain walls is like cutting on the load-bearing walls of a house. The rocks and soil on them will collapse with a rumble.

However, what Xu Dong didn't expect was that this time the mountain was demolished and a big guy was revealed.
