As early as millions of years ago, Zhang Jun also carefully observed whether primates appeared upright walking, and he found that primates appeared earlier than in history, because of the threat of dinosaurs, which caused them to think faster, but they failed to defeat dinosaurs, but chose to migrate north.

As a result of this change, humans did not first appear in Africa, but in fact, human ancestors appeared in ancient China and Europe, where primitive humans with higher intelligence had evolved, and Zhang Jun did not know this very well, because his expeditions to Eurasia were infrequent, and only occasionally went to Eurasia after a million years to explore where the animal evolution was.

Zhang Jun has not entered the northern hemisphere for the past million years, and at this time he needs to go out again to the north to see how much has changed there, which will have a great impact on his future plan of action.

For tens of millions of years, Zhang Jun has been trying to make the alien dragon clan reproduce with the greatest ability, and even did not hesitate to go into battle himself to complete the process of dragon love, Qili has become Zhang Jun's wife, giving birth to many generations of descendants for him, but after hearing that the descendants were separated, many did not escape the fate of extinction, and only a few remained.

"Chief, we went to the north this time, I don't know what changes we can see, a million years have passed unconsciously, I really miss the north a little, I really want to go over and see." Qili lay beside Zhang Jun, looked at Zhang Jun gently, and said in a low voice.

Zhang Jun and Qili already live in a new dragon's nest, which is a courtyard-shaped dragon's nest, spacious and bright, which is the architectural form that Zhang Jun taught to the immortal six dragons before, and their current dragon's nest is no longer a pure cave, or a cave, but a separate and independent dragon nest, each allosaurus couple, will have a separate room, do not interfere with each other.

In addition to Zhang Jun and Qili, who have been a stable couple for thousands of years, the wives of Bald Head and Black Skin, Big El, Little El, and Feigo have been replaced by thousands of them, because their lifespans are too long, and those ladies will die of old age sooner or later, and they will only be replaced by new wives.

After Zhang Jun heard this, he immediately turned his head and responded: "I feel that there seems to be some special changes in the north, we must go over and take a look, otherwise once there are creatures that evolve advanced intelligence, when the time comes, we can only let them ravage, which is very important for the reproduction of the dragon group, although it is still a little dangerous, but we must complete this task." ”

There has always been an important part of Zhang Jun's plan, that is, once there are other intelligent creatures on the earth, then he only has two choices, one is to eliminate them to ensure the absolute powerhouse status of Allosaurus, and the other is to co-opt them and let them be controlled and led by himself and become part of the dragon group, he can't let other intelligent creatures surpass him freely, which is a very dangerous thing.

In history, there have been many massacres of civilization against barbarism, and the Indians of the Americas have been slaughtered by the latecomers, the number of whites, more than 50 million people, and the historical lessons of blood have made Zhang Jun have to monitor the evolution of other animals and make corresponding countermeasures in time.

Coincidentally, Zhang Jun found that in the entire evolutionary history of organisms, except for a few more dinosaur populations, there has not changed much, especially the animal species are basically the same as in history. In addition to the evolution of human beings out of Africa, the evolutionary process has not changed much, and the time nodes of evolution are similar, which may be the result of God's deliberate arrangement.

If according to the original history of the earth's evolution, the first 10,000 years of history is a very important node, and at this time, human beings will slowly appear tribal civilizations with a higher degree of aggregation, so this is the focus of Zhang Jun's northward investigation, he does not want human beings to be so strong that they cannot be defeated, so that they will not be able to gain a foothold.

Before leaving, Zhang Jun explained to several big female dragons according to his previous practice, asked them to take good care of the little dragons, and then went north with the six immortal dragons. At this time, Fei Ge's wyvern only left him and a female dragon, as well as four or five baby dragons, and the number of populations of this size has always been a more suitable combination, too many of them, food supply will be problematic.

The courtyard-style dragon nest where the dragons live today was excavated on a mountain near the original dragon's nest, it has a solid stone exterior wall, in this era, no large carnivorous animal can break into the dragon's nest, and the allosaurus has always been invincible around, so Zhang Jun is not worried about the safety of the population.

After everything was ready, Zhang Jun took the six dragons and some necessary tools and walked towards the northern jungle, in the last few thousand years, Zhang Jun rarely set foot in the realm more than a thousand kilometers away, this time he needed to go out of the area even farther away.

Fei Ge is still free to soar in the sky, it often falls into the jungle to rest, waiting for Zhang Jun to come over, it is the most powerful sentinel and reconnaissance force of the dragon group, often deep into the front of the longer distance detection, and the large flying dragon that can fly in the sky, there is only one kind of colorful flying dragon left, the other flying dragons have become several times smaller, generally only a few times larger than the eagle, some are much smaller, and they look similar to birds.

Fei Ge is invincible in the sky, so it has always been the absolute sky overlord, no one can shake its position, when Zhang Jun and the dragon walked below, Fei Ge shouted a few times below: "Brothers, I went to the front to observe those monsters, you talk slowly, I'm leaving." ”

Zhang Jun glanced up at Fei Ge's extremely bright multicolored feathers, nodded and said, "Go ahead, try to figure out the surrounding situation, the animals in northern Africa may change a lot in the past few thousand years, and transmit information to us in time." ”

Fei Ge nodded in response, then made a beautiful flying gesture and flew forward, its eyes sharp enough to see farther than an eagle, and it was able to catch small rabbit-sized targets on the ground, and then flew slowly towards a jungle ahead.

Along the way, Zhang Jun took the six dragons to walk and rest, every time they went out, they were considered to go out for a trip, after all, in this kind of wild era, living for hundreds of millions of years, itself is a very boring thing, from time to time to go out for a walk, find some freshness, you can also relax your mood.

Unconsciously, they walked out of a distance of more than 1,000 kilometers to the northern region of Africa, at this time, Africa, there are already the Sahara Desert and other desert areas, they deliberately avoided the hot desert areas, walking in the jungle, every time they arrived at a familiar water source, they would carry enough drinking water for a few days, stored in bamboo tubes, and carried on their backs.
