And Zhang Jun can still only concentrate on the ability to integrate hydrophilic ability within hundreds of thousands, and the other energy fusions are in the blank stage.

In the past hundreds of thousands of years, Zhang Jun is still doing another thing, that is, to express some simple words to his companions, such as leaving, he will use two tones to express, and when sleeping, he will use two snapping sounds, and slowly the six immortal dragons gradually understand what Zhang Jun means, and then they will also use the same language to talk.

In hundreds of thousands of years, Zhang Jun only taught Long Qun about a hundred words, most of the commonly used words they know, most of them are survival-related words, such as threatening, ambushing, forward, backward, attacking, asking for help, these battle-related languages, or sleeping, eating meat, drinking water, peeing, poop, these life-related words.

Zhang Jun refers to the six dragons, including Bald Head and Qili, as the Immortal Six Dragons, the most intelligent dinosaurs in the population, who have lived for hundreds of thousands of years and are already familiar with the use of these languages.

And some of the smart Allosaurus in the dragon group will slowly learn some simple words, but most of them only know a few to a dozen words, just like a person teaches a dog some passwords, but they slowly teach these words to their descendants, but there are very few descendants who have the ability to learn these words.

In the first 10,000 years or so, Zhang Jun's professors played a very small role, but as time went on, Zhang Jun had discovered that there was a group of Allosaurus separated from him, and when hunting, they could use two or three simple words to communicate with their companions, apparently those words were invented by themselves, and taught to their parents, who then taught them by their parents.

However, obviously, most of the words that Zhang Jun taught their parents were not inherited by their juniors, so the evolution of language was slower than the body, but Zhang Jun's patience was very sufficient, in addition to these, he also taught Allosaurus the method of making fire, and the experience of building a safer dragon nest, only a small part of the dragon group learned some skills, and drilling wood for fire, basically no Allosaurus would use, because they didn't seem to be very interested.

Of course, the six immortal dragons who follow them all the time have already learned this simple skill, and their wisdom has also been greatly improved, and they know how to use their claws to pluck branches and carry stones, which are much stronger than other Allosaurus.

Then nearly a million years gradually passed, Zhang Jun and the Immortal Six Dragons were still so young, they didn't seem to have changed much, in this million years, their body size has not changed much, because the oversized body is not easy to eat, so it is not that the bigger the body, the better, Zhang Jun deliberately controlled the amount of food.

But millions of years of fighting have made their teeth and claws sharper, their bodies stronger, and the strength of the Immortal Six Dragons is now more than three times that of before.

The speed has also been more than doubled, and they can hold their breath underwater for more than half an hour at a time, and only need to surface once to breathe before continuing their dive.

In addition, their body's ability to resist blows is increased by more than five times, and their recovery ability after injury is increased by more than ten times, and they can basically recover on their own without the need for medicine, which is also an ability that has evolved in long-term battles.

With the fusion with the Star Spirit Crown, Zhang Jun gradually found that his skin began to produce the ability to absorb oxygen every time he dived into the water, this ability changed very slowly, but after a million years, it finally expanded to the ability to allow him to stay underwater indefinitely, and his skin could already absorb oxygen underwater and enter the internal circulation.

Up to now, Zhang Jun already has diving ability comparable to that of fish, and he does not need to surface for ventilation at all, and after a long time of diving practice, his swimming speed is getting faster and faster, and gradually there is no difference between him and fish.

The evolution of the population is still the same as before, and now the dragons in the population have gradually inherited the language of their parents, and they can understand at least a few dozen simple words, all of which are done in simple tones.

Moreover, most of the dinosaurs inherited Zhang Jun's skills in building dragon nests, they learned to pluck tree branches, carry stones, dig pits in the ground and walls to build dragon nests, and learned to block stones at the entrance of the cave to prevent wild beasts from breaking into the hole.

And after the dragon group learned some more skills, their wisdom also began to evolve unconsciously, the brain capacity expanded by one-third, and there is a tendency to continue to expand, of course, some of the differentiated dragon groups will soon forget the wisdom that Zhang Jun taught them, this wisdom is only in the Allosaurus that is closer to Zhang Jun, and it spreads deeper.

"Bald, we're leaving." Zhang Jun walked out of the cave, stretched, and then turned his head to the bald head standing near the entrance of the cave and muttered a few times.

The bald man immediately understood that Zhang Jun was going to take them out of the dragon's den, and in a million years, they had changed their residences dozens of times, because the increase and decrease in the amount of food would make them migrate frequently, and this time Zhang Jun decided to walk east.

The bald man cuckled at the strange dragons in the cave a few times, and soon saw Qili and Blackskin each coming out of different cave entrances with a batch of Allosaurus, and the big El and the little El appeared outside the other cave entrances with another batch of Allosaurus, and they all called out, as if asking where the leader was going this time.

Zhang Jun clucked twice towards the east, and all the Allosaurus understood that the leader was going to take them to the far east to hunt, and they were going to go far away.

"Qili, take my gray cloth bag and don't leave anything behind." Zhang Jun shouted a few more times towards Qili, who was walking towards him with elegant steps.

Qili nodded a few times, then turned the gray cloth bag on her back and let Zhang Jun take a few looks, letting him understand that he had always been a cautious dragon and would never leave any valuables behind.

Since the death of the camel dragon, Qili has taken on the task of managing Zhang Jun's personal belongings, and for millions of years, it has been loyal and dutiful, and has not once disappointed Zhang Jun.

"Chief, we're ready to go." Heipi came over again and whispered twice at Zhang Jun.

Zhang Jing immediately understood the meaning of the black skin, although most of the other Allosaurus only mastered about a hundred words, but the Immortal Six Dragons had almost mastered thousands of words after a million years of training, in fact, it took an average of a thousand years for them to remember one word, which was not too fast.

The Immortal Six Dragons have now evolved to the age when human ancestors began to use stone tools, and their wisdom is also much ahead of other Allosaurus, and they have already possessed a mind that other Allosaurus does not have.

Of course, this is only a crude language, an advanced language has not yet been formed, and writing is a long time ago, and it is impossible to talk about it, and they have not yet reached the point of learning words.
