For words, several other people don't understand much, they only know vulgar language, use simple words to express a certain meaning, the meaning of words has not yet been reflected in front of them, let alone any words and sentences, poems and songs and other advanced text expressions.

Zhang Jun will follow the example of the ancients of the year, and record the text on some bamboo pieces, which directly skipped the oracle bone era, of course, he also wants to make a paper to record the text, but papermaking requires a lot of equipment and technology, and it also takes a long time to study in order to have certain achievements, after all, it is an ancient and modern invention, not a simple few tinkering can be made.

As for the printing technology used in conjunction with papermaking, it is a very difficult invention, Zhang Jun does not have Bi Sheng's technical information back then, so he has no way to start, and he can't complete these things alone, and more people with advanced wisdom in the dragon clan are needed to work together to complete.

Nowadays, the cultural level of the dragon clan has not produced such a high-level thinking at all, and it can complete a great invention and creation, and the low-level tribal society does not need those things at all, they have not even learned to plant, as long as they can hunt, they can meet all the needs of life.

After returning to Africa this time, Zhang Jun will begin to study the relationship between writing and language pronunciation, and strive to slowly form a script that matches the dragon language to promote the development of the dragon society.

"There are no giants and other giant beasts ahead, and it is safe to move forward, but how can that human tribe solve it?" Fei Ge went out to reconnoiter for a while, then flew back and reported to Zhang Jun.

Zhang Jun stood up, stretched his waist, and then said after a little thought: "Destroy their dwellings and drive out the remaining humans, lest we run into these nasty guys when we come back." ”

"Yes!" Fei Ge immediately nodded in response, then turned to Dashan and shouted, "Dashan, take someone with me to destroy those human caves." ”

The mountain immediately began to gather his men and horses, and ran towards a jungle with Feigo, and then the big and small El also shouted and followed, with the help of the two big men, things would be done faster.

Then Zhang Jun and the bald people also began to set off, walking towards the location of the human tribe, and when they arrived at the place where the tribe was, they found that they had stored a lot of stone tools and weapons, as well as fruit food, animal skins and animal bones and other materials.

Fei Ge took the leaping dragon of the mountain, and together with the two uncles of the big and small El, they smashed the human tribe into a mess, and smashed part of their cave with tools, it is estimated that these humans do not dare to live here anymore, because they have lost the protection of the giants, they have been completely exposed, and it is very unsafe to live here, even if the dragons do not clean them up, the surrounding beasts will slowly solve them.

"Let's go!" Finally, under Zhang Jun's order, the dragon group continued to move northeast, and the route they were going to take was from the Middle East to Central Asia.

The current situation is much more complicated than Zhang Jun imagined before, he did not expect that in addition to humans, there are also different races such as Homo erectus and giants, so he previously thought that the journey should be very safe, but now the situation has changed greatly.

Along the way, Zhang Jun may encounter more intelligent creatures and monsters, including those difficult to deal with behemoths, and maybe more powerful tribes, so everything needs to be determined according to the actual situation, if the danger ahead is too huge, then Zhang Jun can only give up part of the original plan, return to Africa as soon as possible, take root in Africa, slowly develop his own population, and then gradually return to Eurasia when the dragon clan is strong enough.

Unconsciously, the dragon herd has passed through Iraq, Iran, and arrived in the north of northern Iran, probably the southern region of Kazakhstan, which already belongs to a typical Central Asia, and then walk more than a thousand kilometers to the east, you can enter western China, of course, at this time it is still barren land.

Along the way, Zhang Jun only found two or three human tribes, all of them were very few in number, only a few dozen people, and the level of civilization varied, some tribes only used the simplest tools, and some were using more advanced tools.

These humans were already frightened to avoid the dragons when they saw them, and they were powerless to compete with the dragons, and there were many kinds of wild beasts living in this area, such as Asian tigers, elephants, cows, horses, and steppe wolves.

And Zhang Jun also found that among these populations, there are generally the shadows of intelligent creatures, at least he once saw a few upright walking cattle running on the grass, they have evolved their palms, and they were chasing a group of steppe wolves, at this time the status of steppe wolves and cattle was reversed, and the original predators became food for cattle.

All this is the result of wisdom, some of the cattle are no longer pure herbivores, their ancestors at a certain historical moment, have gradually adapted to meat, and the large amount of protein in meat will also promote the expansion of their brain capacity, thus further producing higher wisdom.

But Zhang Jun's overall feeling is that the number of intelligent creatures is too small compared to wild beasts, and the sporadic tribal civilizations are far from forming a climate, so he also roughly understands the evolution of creatures in Asia, at least human beings are not yet prosperous, and other intelligent creatures are the same, they are still only in the primitive society stage, and the number is small.

Along the way, they experienced a lot of scenery, the dragon group ate a lot of game, what tiger meat, leopard meat, everything tasted, and then after passing through a large desert edge area, the dragon group entered the jungle again, this is a vast jungle area, usually under this geographical environment, there will be all kinds of wild beasts, Zhang Jun hopes to see a different face.

When the dragons came to a dense forest, they found that the beasts here were gradually increasing, and their huge bodies were enough for all the beasts to avoid themselves, and naturally they did not encounter resistance, but as they gradually penetrated hundreds of kilometers into this jungle, the situation changed.

"It's so quiet here, it seems that there aren't as many beasts as there were a few days ago." Qili walked beside Zhang Jun, she felt the silence in the jungle, and said immediately.

Zhang Jun has long been aware of this, usually a relatively quiet jungle may be inhabited by a certain type of beast, because other animals will avoid the habitat of the beast and migrate to other areas.

Fei Ge flapped his wings and flew ahead, trying to scout if there were any other animals in front of him, so he flew out for several miles before finally flying back.

From Fei Ge's eyes, Zhang Jun seemed to see that he had made a discovery, and after Fei Ge came down, he really said to Zhang Jun: "Chief, we need to go around to a mountain ridge on the left to observe, there is a discovery ahead." ”

"Feige, what do you see?" Blackskin didn't speak, but he also saw the surprise written on Feigo's face and immediately asked.

"There are a few monsters in front, all of them are very large, and the largest one is not much different from us, I don't know what kind it is?" Fei Ge said with a look of surprise in his eyes.

Zhang Jun was slightly stunned, this is another large animal found by the dragon group after the giants, which indicates that the large creatures on the earth have evolved a new batch of huge species since the extinction of the dinosaurs, which is somewhat different from the previous history of earth evolution, and the history of biological evolution seems to have been rewritten.

"Do those guys look like dinosaurs?" Zhang Jun is concerned about whether these monsters are their own kind, although this possible surname is not large, but it does not exclude a small number of Allosaurus, which retains the characteristics of huge size and continues to this day, and still survives in other regions.

Fei Ge immediately shook his head and said, "These guys are not dinosaurs at all, they are mammals, and I saw a monster gnawing on the roots of a big tree, it seems that it is some kind of omnivore, not an ordinary carnivore." ”

Zhang Junguang listened to Fei Ge's description and couldn't see anything famous, so he nodded and said, "Then let's go and see clearly, if we find that they are not too threatening, these unlucky guys can just fill our stomachs." ”

The dragons haven't eaten for a long time, and recently they have been eating some small animals along the road, killing one by one, so that they can barely fill their stomachs, and if there is a large prey belly, they don't have to work so hard, they can keep them for several days without eating at a time.

"Let's go to the left, without further ado, or the monsters will slip away!" Zhang Jun then pointed to a mountain ridge on the left, and then ordered.

Then the dragons changed the direction they had intended to go, and began to move to the left, and after gradually walking a few miles, they climbed up a mountain, where Feige had been waiting, he had been lying behind a rock, observing an animal below the mountain for a long time.

When Zhang Jun climbed up, he found a favorable terrain to hide, and began to observe the monsters below, at this time, several faintly visible shadows were moving in the jungle, there were about three or five of them, and the size was indeed very large, one of them was more than four meters tall, and the weight seemed to be about two or three tons, and the rest of the bodies were also three meters taller.

Zhang Jun took a closer look and found that they looked very much like enlarged versions of mice, their appearance was similar to that of voles, with gray fur, two big ears erected, small eyes, and pointed beaks, which were not much different from the shape of mice, but they were ten million times larger.

The giant rats were digging the roots of several large trees nearby, and then digging out their tender roots and eating them, while some of the giant rats were gnawing on the wild fruits and leaves around them, and it seemed that they had a wide range of food, but it was not known whether they were carnivores or not.

Zhang Jun's mind felt a little shocked again, if the Homo erectus and giants encountered before were just accidental, today's encounter further proves one point, that is, the biological diversity on the earth, far beyond the original appearance of the original history, after hundreds of millions of years of evolution, the era of giant beasts seems to be reappearing, but they are not dinosaurs, but emerging giant mammals, which Zhang Jun did not expect, it can be said that he thought that this is the result from far away.
