After a few days of observation, Zhang Jun was able to figure out the environment around him, and only a few smaller animals could be found in the area, which could burrow into the dense forest and look for reptiles and polydonts hiding in the grass.

In the grass, in addition to snakes, there are lizards, and there are also animals that transition between lizards and snakes, earthworms, earthworms look like earthworms, but they are as long as snakes, and there are traces of limbs on their bodies, indicating that their limbs have degenerated, from lizards to snakes.

Polydontas are early mammals, they are generally very small, look like rodent mice, but they are not rodents, they have not evolved large ears, they are also insects and plants as their main food, and they are omnivores.

In the past few days, Zhang Jun has seen that around his big hole, there are several litters of multi-tumor tooth beasts living in several small holes, which are larger than the mice of later generations, smaller than domestic cats, and look fat. None of them found themselves a dangerous neighbor, because dinosaurs didn't burrow under the surface.

Zhang Jun plans to find a time to take a nest of multi-tumor tooth beasts, which should be able to catch several fat guys, enough for him to eat a full meal, and then go without food for a few weeks.

In addition to Zhang Jun, there are four or five small allosaurs that look exactly like him moving around, they all live in darker places, take shelter with the help of terrain, come out to forage during the day, as long as the animals smaller than their size, they eat almost everything.

Zhang Jun, these Allosaurus brothers, are not skilled enough in hunting, but they run at a good speed, and are good at turning and jumping to chase prey, but sometimes there is no good way to encounter animals that can drill holes.

Zhang Jun is playing another set, completely taking the ambush way to hunt, waiting for the rabbit, and when the prey passes from the door, suddenly attack, lightning attack, and lightning back to the nest, in order to reduce their own danger, this hunting method requires extreme patience, the success rate is higher than wandering around, but sometimes several days can not wait for good prey.

However, Zhang Jun estimated that it would not be long before the small animals around him might be eaten by him, and he would have to venture a little farther away to hunt for food, but his plan was that it would be best not to get out of this dense forest in the near future.

Zhang Jun also found that in a distant place, there will occasionally be large dinosaurs passing by, and often make fierce roars, which seem to be the sound of animals fighting, perhaps the carnivorous dinosaurs are hunting large prey, judging from the size of their voices, the volume of those dinosaurs must be very large, and they belong to the kind that can trample on small dinosaurs with one foot.

Recently, Zhang Jun took a nest of polyodonts and caught four fat big guys, because they looked like mice, Zhang Jun named them Mickey Mouse, he had not seen this animal prototype on the science and education channel, only knew that their genus was polymadont.

In the following months, Zhang Jun found that there were several Allosaurus with a body size of more than three meters, entering this area to feed, fortunately he was very cautious and very familiar with the surrounding environment, so he did not meet those big guys, although he had the ability to fight with it at this time, but he did not want to be injured because of this, and it was useless to sacrifice, which was very troublesome for himself.

The rainfall here is abundant, and Zhang Jun found a few stones as containers to collect rainwater and store it in the cave for drinking, which is enough to run far away to venturize.

Zhang Jun found that two or three of his brothers had never returned to his den after they had walked out of the jungle, and two of his brothers had returned bleeding and wounded, one of whom died not long after.

Its corpse was eaten by several Archaeopteryx, Zhang Jun didn't make a move, he didn't plan to nibble on his own kind for the time being, and human consciousness still had a great impact on him.

In this way, Zhang Jun carefully lived in this palm-sized jungle, did not go out once, and a year later, his size more than doubled unconsciously, his body exceeded 1.5 meters, and his weight exceeded 100 kilograms.

And Zhang Jun's brothers, none of them survived, and the last one was suddenly broken in by a dinosaur more than three meters long two months ago, bitten to death and dragged away.

The intruder was also an Allosaurus, and so far, several Allosaurus brothers who were born at the same time as Zhang Jun have all disappeared in the jungle one after another, leaving him alone in this jungle.

As Zhang Jun's size gradually increased, his food intake had increased by two or three times, and he needed to drink a lot of water, and gradually he found that the food around him did not make him feel as full as before, and after a while, he had to go a little farther to forage for food.

Zhang Jun does not intend to give up this cave, in the past year, he has not only expanded the nest, has been more than ten meters away in the hidden place, digging another escape hole, and placed some sharp grass thorns in the hole, even if an animal breaks in, can not pass through the sharp thorns, deep into the cave to chase him, the role of wisdom has been well played by him.

And Zhang Jun's Yi Jin Jing and Iron Cloth Shirt Kung Fu have made great progress, the blood in the body is smooth, the true qi is full, and it has become lighter and more flexible, and the bounce power is more than twice as good as that of dinosaurs of the same size, and after a year of iron sand palm practice, the force of his claw is more than three times greater than that of ordinary dinosaurs, which can be described as full of strength.

When Zhang Jun was fine, he slammed the cave wall with his claws in the cave, one was to dig the hole, and the other was to practice iron sand palms and fists, killing two birds with one stone, and his strength grew rapidly.

"It's suffocating to stay in the cave, and now I can finally go out and bask in the sun!" Zhang Jun walked out of the cave and stretched, ready to go to a farther place to move.

According to Zhang Jun's observation for a year, large dinosaurs often pass by in the northwest direction, and sometimes go back and forth, so he judged that there may be a water source in the northwest direction, and he is ready to go over to see what is going on, so as to open the way for solving his drinking water problem in the future.

Before leaving, Zhang Jun made a full camouflage around his cave entrance, and then went to a Mickey Mouse's nest dozens of meters away, ate a full meal, and began to move towards the northwest.

After getting bigger, Zhang Jun also became more generous when he walked, no longer looking shrunken and sneaky, he strode through the dense grass, and gradually walked out to the vicinity of the place where he was born before.

This place is very open to allow large dinosaurs to pass through, and the jungle has left huge footprints of large dinosaurs like footbaths, so Zhang Jun must be careful, he knows that his kind is very good at ambushes, and pays special attention to the hidden places in the grass, and tries not to go to places where the line of sight is not clear.
