There is only one way to ensure that the food can meet the needs, that is, the number of allosaurs in an area cannot exceed the limit, which requires Zhang Jun to deliberately control the number of dragons, and the only way is to control the number of dragons born, which is also a bit similar to human family planning.

"Is there a need for this?" Zhang Jun began to be confused, and he still had a lot of unknown areas to explore in this world.

Zhang Jun thought about it, and finally decided that he could not rely on the method of controlling the number of dragons to solve this problem, he felt that the best way was that after the young dragons in the dragon group grew up, they must stay in other areas, and then drive them out, let them survive independently, and form a new dragon group, so that the number of allosaurs can be expanded without limit, and the dragon group under his command will not lack food.

If Zhang Jun continues to work hard for a long time in millions of years, countless new Allosaurus groups will be born in his hands, and these differentiated Allosaurus groups will definitely continue to expand in various regions of the earth, becoming the only carnivorous animal with absolute dominance, and other animals will survive in the cracks of Allosaurus, just like the fate of other animals when humans ruled the earth, and letting people slaughter has become the fate of the vast majority of animals.

Zhang Jun then determined the number of his ideal dragon group, about 30 large dinosaurs, about 50 small dinosaurs, and when the small dinosaurs grow up, Zhang Jun will expel the excess number of dinosaurs from the dragon group and let them fend for themselves, and the dinosaurs that remain in the dragon group, he will try his best to pass on his wisdom to them, so that they can learn some intelligent creatures after long-term imitation, such as using fire, using tools to build dragon nests, etc.

These are long-term goals, which may not be accomplished in a million years, but perhaps Zhang Jun's wisdom can make the evolution of dragons much faster than the evolution of apes to humans.

If after millions of years, perhaps tens of millions of years later, in the Fifth Mass Extinction Era, Allosaurus really succeeded in evolving into an intelligent species, then the mass extinction at that time would also make civilization disappear again, so we can only use the Time and Space Temple to preserve part of the civilization achievements, and let some of the more intelligent Allosaurus survive in the Time and Space Temple.

Time is still far away, this is just a plan and an idea, Zhang Jun does not know what kind of results his efforts will achieve, everything is still unknown, and he must go through countless practices before he can draw conclusions.

"The days are so long, how can Brother Brother?" After Zhang Jun's life extension was extended, he felt even more lonely and bored, and this loneliness would last for millions, if not billions of years.

Zhang Jun then took the dragons to stay on this huge island, and soon he finished inspecting the entire island, and found that this island was an astonishing 500,000 square kilometers, with a diameter of about 700 kilometers.

Among them is a huge pterosaur that attacked Zhang Jun on Chinese New Year's Eve, its habitat is on the reef in the east of the island, and a large area in the east is its sphere of influence, Zhang Jun's sphere of influence is in the central and western regions, and one-third of the area of the giant island is occupied by him.

Due to the abundant food in their respective territories, Zhang Jun did not plan to provoke this pterosaur before leaving the giant island, there is another fierce python giant, in addition to Zhang Jun and the territory of the pterosaur, several other areas are occupied by several huge pythons, and there may be unknown creatures that have not been discovered.

In order to achieve his goal as soon as possible, Zhang Jun did a thing to force good people to become prostitutes, he let male dragons and female dragons mate frequently during the estrus period, and one female dragon has mated with at least three or more male dragons. The end result is that at least three female dragons become pregnant and lay eggs every year.

On average, the number of dragons will increase by twenty or thirty every year, and after five years, the original dozen or so dragons have grown more than five meters, and they all weigh more than one ton.

In five years, the number of dragons has expanded to one hundred and six, of which there are only more than 20 dinosaurs that are more than five meters long, and most of the dinosaurs are small dragons less than four meters long.

The number of dragons slightly exceeded his predetermined goal, but a few more dragons did not change much of a food need, so Zhang Jun decided to take them on the road and prepare to travel west.

If the number of dragons will be reduced, Zhang Jun will take away the hatchlings hatched by the eggs laid by the female dragon, and if there are too many of them, Zhang Jun will only drive some dinosaurs out of the group, including the possibility of abandoning the dinosaur eggs directly.

For more than five years, Zhang Jun has been very familiar with this territory, the evil dragons that escaped back then seem to have grown again in another area, Zhang Jun after several encirclements and suppressions, but failed to make this little dinosaur who is good at hiding completely extinct, their number has expanded to more than fifty, but most of them are young dragons.

If it weren't for Zhang Jun's early plan to leave the island, he would definitely not let the evil dragon breed again, but it doesn't matter at this time, it is estimated that as soon as he leaves, the evil dragon group will make a comeback, and this jungle will return to its original appearance five years ago, as if Zhang Jun has never been here.

Before each long migration, Zhang Jun will do the same thing, that is, try his best to hunt more animals and store more energy in his body to ensure that he can survive hunger for a longer time on the way.

Now in the more than a dozen caves on the top of the mountain, almost all of them have the figure of Allosaurus, and the little dragon is concentrated in the middle of the cave, as long as Zhang Jun summons, nearly eighty little dragons will come out of the cave and follow him out to hunt.

Among the dragons, only one was over thirty years old and looked like an old dragon clock, and the rest of the dinosaurs were still young, and the old dragon walked at the front of the group, and it was responsible for leading the way, because it was the most experienced.

The little dragons all followed behind Zhang Jun and the old dragon with a lot of wrinkled skin, and began to descend the mountain in a mighty way, and this time, they will never come back, there are some experienced allosaurs, from Zhang Jun's long cry, he has heard that he is going to lead the dragon group to migrate.

Because before each migration, Zhang Jun will make this trombone-like sound, this special sound is remembered by some Allosaurus, they are the third time to follow Zhang Jun to change maps, it is estimated that they have long been used to it.

Most of the dragons thought it was just a routine hunt, that they had a stronger attachment to the dragon's nest and that they were in awe of the world full of dangers, and that if it weren't for Zhang Jun forcing them to migrate, they would have stayed here until they were more than five meters long before they gradually moved away from the dragon's nest.
