The little dragon has not been eliminated by nature, and the problem brought about by this is food shortage, just like human beings in the 21st century, due to the role of scientific and technological civilization in life support, the population has skyrocketed from more than 1 billion in the 19th century to 7 billion, and the food problem has become more and more important.

With the expansion of the dragon group, Zhang Jun's encounter with this problem will become more and more obvious, and it is impossible for him to teach the breeding techniques he knows to Allosaurus, otherwise the problem will be solved, and he will have to keep looking for more food resources.

After eating, Zhang Jun began to take the dragons to the east, which is the most likely place to have a water source, as long as the water source is found, the footprints of those large animals will be revealed, these days the dragons are relying on the rain gathered in the low-lying areas of the jungle to survive, now the water on the ground has dried up, and there is no more water to quote.

Fortunately, the dragon group can not eat for a week, and can always look for a water source, in a week, the dragon group can go out more than a hundred kilometers, and should be able to find a water source in the distance, otherwise those local residents, evil dragons and pythons will not live for so long.

The jungle in the east was even denser, and the results of the search did not discourage Zhang Jun, and the dragon group did not go too far, but after walking out for about ten kilometers, he found a huge lake, which was located behind a hill.

When Zhang Jun saw the lake, his eyes immediately widened with excitement, it was a large lake with a width of more than five thousand meters, the water of the lake was very clear, and the riverbed at the bottom of the water could be seen in some places, and there were occasionally some green plants floating in the lake, and the shore was covered with big trees and wild grasses.

Smelling the fresh smell of the lake, the dragons were excited, Zhang Jun didn't see other animals on the lake, so he immediately chose a lake shore and stopped, he began to observe the nearby situation, and needed to find a safe place to drink.

This lake is supposed to be the largest source of water in the vicinity, and it doesn't mean that there are no animals drinking water around it, and because it is surrounded by dense forests and tall plants, you can't see too far from the left and right sides.

Fortunately, this lake is not too far from the dragon's den, and you can walk back and forth a day, so the dragon group can use this place as the main hunting ground, and large animals will definitely appear here.

Zhang Jun found a water meadow submerged in the lake, the water grass here is only a foot long, and it rises out of the lake, wafting in the wind, emitting bursts of grass fragrance, and it is safe to drink water in this place.

Zhang Jun didn't know if the lake was connected to the sea, but if it did, the water here would be salty, so he immediately tried to smell it and didn't find the smell of the sea.

Zhang Jun judged that there should be no sea creatures such as plesiosaurs and ichthyosaurs, only animals such as crocodiles, and he asked the dragons to line up to drink water, so that everyone would not be crowded together, so that it was easy for predators to find and choose suitable targets.

Zhang Jun put his mouth into the lake and drank for a while, and then withdrew from the water meadow, allowing other dinosaurs to continue drinking, when the little dragon drank, Zhang Jun was with him, once he found any movement in the lake, he would immediately drink the little dragons back to ensure their safety.

There were a few unruly Allosaurus who ran to the side of the deep water, hooked their necks to drink the water in the lake, and were immediately roared back by Zhang Jun, Zhang Jun did not allow the dragons to take such a risk, with his wisdom dragon, he did not allow any unnecessary non-combat attrition.

Seeing that the leader was really angry, the Allosaurus retreated a little reluctantly, and honestly stayed behind the other Allosaurus and lined up, waiting for drinking water, which was very rare in the Jurassic, and almost no animal would form an order when drinking.

During the dragon group drinking water, Zhang Jun saw that there were some ripples in the lake, and there seemed to be some kind of creature lurking in it, but the shallow water area he chose was obviously not suitable for large creatures in the water to swim, in order to ensure safety, Zhang Jun broke a branch and crossed the edge of the lake, so that once an animal appeared, it was necessary to cross this branch first in order to continue to move forward, and when the time came, the dragon group would have enough time to find the enemy, so as to react as soon as possible.

During the drinking of other Allosaurus, Zhang Jun has been observing the nearby jungle to see if there are any large dinosaur footprints, and after looking for a while, he still found that in the jungle a few hundred meters away on the left, several tall figures suddenly appeared. It was a dinosaur with armor on its body, and it looked like a samurai in armor, with armor on its body covering the skin surface of its entire back, and even its scalp was made up of armor, and the blue-gray armor extended to the tail, almost fully armed.

Zhang Jun guessed that this should be an early ankylosaurus, this kind of ankylosaurus is covered in armor, once attacked, it is possible to lie on the ground like a turtle, and the teeth of ordinary carnivores will be broken when they touch its armor, so they are not afraid of the bite of ordinary animals, armor is their best weapon for self-defense, and their tails look very stout, which seems to have some weight, and once attacked, they will launch a ruthless attack on their opponents.

Zhang Jun has already eaten enough, this time these ankylosaurs are lucky, they can still get away with a group of tough meat eaters, and next time I am afraid they will become Zhang Jun's meal. However, Zhang Jun wanted to see if the armor on the ankylosaurus's body could not bite with his teeth as in the legend.

The body size of those Ankylosaurus is not small, the body length is more than seven or eight meters, and the body is very thick, although it is shorter than the body length of Allosaurus, but the weight is estimated to have already surpassed Allosaurus, and it is a group of fat big guys.

At first, it thought that Zhang Jun was a group of herbivorous dinosaurs, and they were here to drink water like themselves, but after careful observation, its keen vision saw the sharp teeth of an Allosaurus when it opened its mouth.

Immediately, the ankylosaurus let out a high-pitched cry, as if to alert several other accomplices who were drinking water, that they had been targeted by a group of carnivores, and after the ankylosaurus screamed, the five or six ankylosaurs immediately gave up drinking water, turned around and ran frantically into the jungle.

"My brother has no appetite today, so he doesn't have to run so fast." Zhang Jun shook his head and sighed in his heart.
