A few hours later, Zhang Jun caught five fish more than half a meter long, dozens of small shrimp, and several incomprehensible mollusks and hard-shells, some of which looked like snails, and some of which looked like crabs with carapaces.

Zhang Jun's diet has never been so messy, usually eat a single dinosaur meat more, at most eat a little lizard and a little thicker snakes, occasionally lucky can catch a few birds and pterodactyls drinking water by the river, today I ate more than a dozen kinds of seafood, it can be said that all kinds of nutrients are complete.

Zhang Jun survived the lack of food by eating seafood along the way, and after about ten days, the dragons gradually entered a bright green jungle, where there was no poisonous gas, there was a flourishing vegetation everywhere, and the cries of animals could gradually be heard, and all kinds of birds began to be seen on the trees, and reptiles and flying insects appeared on the ground, but they did not see too many small lizards and snakes.

At this time, the long-awaited mountain peak was already more than a hundred kilometers away from here, Zhang Jun had already circled to the back of the peak, and then he did not hesitate to take the dragon group and detour forward, gradually approaching the mountain peak.

There are more and more animals in the jungle, Zhang Jun's familiar snakes and lizards are gradually revealed, birds in the sky are flying around, colorful, and occasionally one or two pterosaurs fly over from the coast to find some food in the jungle, which is full of life.

The environment of the giant island does not seem to be much different from the outside of the island, except for the huge area of poison gas, the rest of the place seems to be normal.

Zhang Jun was walking forward, a pile of wild grass in the grass suddenly moved, other Allosaurus may not have noticed, but Zhang Jun's vision was extremely keen, he immediately saw a long tail exposed, it was a big gray tail covered with fluff, and the weasel's tail looked a little similar, but slightly longer.

Before the tail could continue to flutter forward, a tall figure suddenly descended in mid-air, followed by a sharp mouth full of fangs, and bit the tail in one bite.

The owner of the tail was suddenly frightened and jumped in place, but it had been pressed down on the back by a huge claw, and then it stayed on the ground honestly, no longer struggling, because it knew that it was facing a group of huge dinosaurs, and there was no way to run.

Zhang Jun pressed this guy on the grass, he was not in a hurry to eat it, but was studying the body of this guy, he found that this guy had a long gray hair, and the whole looked like a mouse, but basically he couldn't see the big outer ears, the eyes were small, but the body was quite fat, and the claws were also very short, so it didn't look sharp.

Zhang Jun immediately judged that this was a multi-lodonted beast similar to a rice possum, which was very common in this world, but they had been oppressed by dinosaurs and could only hide in the burrow to survive.

This guy's body is a little large, about one meter and a half meters long, and about half a meter high, which is several times the size of the multi-tumor tooth beast that Zhang Jun has seen, which looks a little unbelievable.

Zhang Jun has always suspected one thing, that is, some animals in this area are too large, and the only way to do this is evolution and genetic mutation, and evolution takes hundreds of millions of years to complete, and only genetic mutation will make the size of animals larger in a short period of time.

Zhang Jun was not sure, he always felt that there must be some kind of extraordinary energy in the vicinity, which caused the size of the animal to change dramatically, and it could be seen from the appearance of the five-pointed star blades that there seemed to be something unusual here, and he wanted to find out the reason.

This mammal is the ancestor of humans, but Zhang Jun was a little hungry at this time, so he didn't care so much, and quickly ate this guy alive and filled his stomach.

The forest was originally quite quiet, after the dragon group entered, it caused a huge riot everywhere, the small animals ran around, hidden, after walking a few kilometers, there were no other dinosaurs active here, Zhang Jun has always felt that this island does not belong to the control of dinosaurs, maybe there are other species here to dominate.

If there are no large animals here, just eating these small animals, the dragons will not be able to fill their stomachs, and sooner or later they will have to go to the beach to catch fish and shrimp to eat.

After continuing to go deeper, I finally saw a few large lizards, crawling around, and were decisively killed by Zhang Jun.

Along the way, the dragons caught hundreds of small animals, and on average, each Allosaurus ate more than a dozen small snakes, small lizards, and some even insects, and even disgusting cockroaches.

The terrain here is not too undulating, except for the mountain peak in the distance is still standing, Zhang Jun did not see other tall obstacles blocking the way, and he advanced smoothly all the way, until he was about ten kilometers away from the peak, Zhang Jun was immediately stunned by the scene in front of him.

Zhang Jun found that this vibrant jungle was gradually coming to an end, and what appeared in front of him was a huge pit, which seemed to be more than a kilometer in diameter, and a large area around it was occupied by this pit, and inside the pit was a blue-gray rock and soil, without any plants in it.

The pit is circular, with some low bryophytes growing on the edges around it, and along a slope of about thirty degrees, you can walk to the bottom of the pit, the bottom of which is about twenty or thirty meters deep from the ground, and you need to walk dozens of meters to reach it.

The dragons stood in front of this huge pit, all at a loss, and of course the other Allosaurus did not have the slightest interest in the giant pit, because it was impossible to find a little food in it, only Zhang Jun decided to go to the pit to have a look.

At the other end of the pit is the peak, which stands on the edge of the crater, and looks a bit vicissitudes, and from here you can see the high cliffs on the peak, where there is a pitch black cliff, which is a little different from the cliffs in other places, as if it had been burned by fire.

Zhang Jun walked down to the bottom of the pit with the dragon group without hesitation, the ground on the slope was relatively hard, there had been no rain in the past few days, and there were no obstacles to block it, so the walking speed was faster, and soon Zhang Jun walked to the bottom of the pit.

Zhang Jun found that the rock and soil in this pit seemed to be very different from other places, and the color was dark, and according to his knowledge, he thought that this would not be a crater.

If such a huge meteorite falls on the earth, then I am afraid that the earth will not be able to withstand it for a long time, and at least it will lead to the extinction of a large part of life.

Zhang Jun knows that in ancient times, there were four mass extinction events on the earth, the most recent of which was 185 million years ago, and in that event, it was very prosperous, and more than 80% of reptiles were extinct all over the world.
